RELATED APPLICATIONS
[0001] This application is a continuation in part of, and claims the benefit of,
U.S. Patent Application No. 14/141,224, entitled "Plastic Container with Strapped Base," filed on December 26, 2013, which
claims the benefit of
U.S. Provisional Application No. 61/746,535, filed on December 27, 2012.
FIELD
[0002] The present application generally relates to plastic containers, particularly to
plastic containers designed to hold liquids while resisting deformation.
BACKGROUND
[0003] Plastic containers have been used as a replacement for glass or metal containers
in the packaging of beverages for several decades. The most common plastic used in
making beverage containers today is polyethylene terephthalate (PET). Containers made
of PET are transparent, thin-walled, and have the ability to maintain their shape
by withstanding the force exerted on the walls of the container by their contents.
PET resins are also reasonably priced and easy to process. PET bottles are generally
made by a process that includes the blow-molding of plastic preforms which have been
made by injection molding of the PET resin.
[0004] Advantages of plastic packaging include lighter weight and decreased breakage as
compared to glass, and lower costs overall when taking both production and transportation
into account. Although plastic packaging is lighter in weight than glass, there is
still great interest in creating the lightest possible plastic packaging so as to
maximize the cost savings in both transportation and manufacturing by making and using
containers that contain less plastic, while still exhibiting good mechanical properties.
SUMMARY
[0005] The bottling industry is moving in the direction of removing auxiliary packaging
from cases or pallets. A case of bottles with film only and no paperboard is called
a "film only conversion" or "lightweighting" of auxiliary packaging. The removal of
supporting elements such as paperboard places additional stress on a bottle, which
increases the structural demands on the bottle. In certain embodiments, a bottle design
can provide one or more of the benefits of reducing bending and point loading failures.
The disclosed design embodiments can alleviate the stresses during shipping and handling
(including film only packaging) while maintaining ease of blow molding. In certain
embodiments, a bottle design uses less resin for the same or similar mechanical performance,
resulting in a lightweight product.
[0006] Embodiments of the bottle disclosed herein may use polyethylene terephthalate (PET),
which has viscoelastic properties of creep and relaxation. As a plastic, PET and other
resins tend to relax at temperatures normally seen during use. This relaxation is
a time dependent stress relieving response to strain. Bending can provide exaggerated
strains over what would be seen in tensile loading. Due to exaggerated strains, the
relaxation in bending can be much more severe. Bending happens at multiple length
scales. Bending can happen at the length scale of the bottle or on a small length
scale. An example of the bottle length scale bending is a person bending the bottle
in his/her hands, or bending experienced during packing in a case on a pallet. An
example of the small scale is the flexing or folding of ribs or other small features
on the wall of the bottle. In response to loads at the first, larger length scale,
ribs flex at the local, smaller length scale. When they are held in this position
with time, the ribs will permanently deform through relaxation.
[0007] Further, embodiments of the bottles disclosed herein may undergo pressurization.
Pressure inside a bottle can be due to the bottle containing a carbonated beverage.
Pressure inside a bottle can be due to pressurization procedures or processes performed
during bottling and packaging. For example, a bottle can be pressurized to help the
bottle retain its shape. As another example, the bottle can be pressurized with certain
gases to help preserve a beverage contained in the bottle.
[0008] Embodiments of the bottles disclosed herein have varying depth ribs that achieve
a balance of strength and rigidity to resist the bending described above while maintaining
hoop strength, such as, for example, when pressure is not used or relieved. A collection
of flattened and/or shallow depth ribs act as recessed columns in the body of the
bottle that distribute bending and top load forces along the wall to resist leaning,
stretching, and crumbling. The collection of flattened and/or shallow depth ribs can
help the bottle retain its shape during pressurization, such as, for example, help
inhibit stretching of the bottle when pressurized. Inhibiting stretching of the bottle
helps retain desired bottle shape to aid in packaging of the bottles as discussed
herein by, for example, maintaining a substantially constant height of the bottle.
Inhibiting stretching of the bottle can help with applying a label to a label portion
of the bottle. For example, with a label applied to a bottle, inhibiting stretching
of the bottle helps retain a constant length or height of the bottle at the label
panel portion, which can help prevent tearing of the label and/or prevent the label
from at least partially separating from the bottle (i.e., failure of the adhesive
between the bottle and the label). Further details on the features and functions of
varying depth ribs are disclosed in
U.S. Patent Application Serial No. 13/705,040, entitled "Plastic Container with Varying Depth Ribs," filed on December 4, 2012,
now
U.S. Patent No. 8,556,098, entitled "Plastic Container Having Sidewall Ribs with Varying Depth," which claims
benefit to
U.S. Provisional Patent Application Serial No. 61/567,086, entitled "Plastic Container with Varying Depth Ribs," filed on December 5, 2011.
[0009] A balance may be achieved between flattened and/or shallow ribs and deep ribs to
attain a desired resistance to bending, leaning, and/or stretching while maintaining
stiffness in a lightweight bottle. In some embodiments, at least some of the aforementioned
desired qualities may be further achieved through a steeper bell portion of a bottle.
A steeper bell portion can increase top load performance in a lightweight bell. A
lightweight bottle body and bell leaves more resin for a thicker base of the bottle,
which can increase stability. A thicker base may better resist bending and top load
forces and benefits designs with a larger base diameter with respect to the bottle
diameter for tolerance even when the base is damaged during packaging, shipping, and/or
handling.
[0010] Embodiments disclosed herein have a base rib that can function as a strap from a
base to a sidewall of the bottle to the help further achieve resistance to bending,
leaning, stretching and/or flexing while maintaining stiffness. A strap rib on a base
helps the base resist deformation under pressure without necessitating the base being
overly heavy in weight relative to the lightweight bottle (i.e., relative to wall
thickness of flat foot base that does not resist pressure as well). The strap base
rib can be incorporated into a flat foot base. A flat foot base helps retain base
foot thickness. Retaining base foot thickness helps retain bottle integrity during
packaging and handling using lightweight packaging, such as, for example, film only
packaging that requires the base to directly resist forces, including bending and
point loading, during packaging, shipping, and/or handling. A flat foot base performs
well with or without internal pressure due to, for example, the ability to maintain
relative foot thickness in the base in a lightweight bottle. Without strap ribs, the
base may have little internal pressure resistance and may rollout (pop out and create
a rocker bottom). The strapped base rib helps resist damage and deformation as discussed
herein without requiring a relatively heavy footed base. Without requiring a relatively
heavy footed base, less material is needed for the lightweight bottle. Further, the
strapped base design may allow for a relatively easier blowing process than other
known pressure bases. Thus, a base with a strap rib as disclosed herein provides for
a material efficient, pressure optional bottle base.
[0011] Incorporating a strap base rib into the base with column formations in the sidewall
of the bottle as discussed herein offers pressure resistance for internally pressurized
bottles while maintaining strength and performance (i.e., resistance to bending and
leaning) when without internal pressure (i.e., pressure release by a user opening
a closure of a bottle). The strap base rib can act with the column formation on the
sidewall of the bottle to form straps around the bottle to communicate stresses along
the height of the bottle.
[0012] The base with a strap base rib helps maintain strength and performance of the column
formations for internally pressurized bottles. With a strap base rib, the resistance
to bending, leaning, and/or stretching while maintaining stiffness and hoop strength
is maintained without pressure while enhancing these characteristics when the bottle
is pressurized. For example, a strap base rib allows the utilization of a flat foot
base for better base strength during processing at a plant (i.e., adding beverage
contents), while preventing rollout or popping out of the base during pressurization.
Rollout of the base bottle leads to what may be called a "rocker bottom." Preventing
rollout of the base helps the bottle stay level when resting on a surface and maintains
the flat feet as the contact points on the surface. Further, base rollout can also
occur without pressurization or low pressurization of the bottle, such as, for example,
during shipping and handling or filling at high speed. A strap base rib also helps
prevent base rollout without or low internal pressurization. While the specification
herein may discuss preventing or inhibiting deformation under external/internal pressures
and/or forces, it is to be understood that some deformation of a bottle may occur
without straying outside of the scope of this disclosure. Some deformation of the
bottle under external/internal pressures and/or forces may occur while retaining excellent
structural properties of the features and functions disclosed herein.
[0013] Embodiments disclosed herein can be utilized for bottle pressures of a wide range.
The strap base rib can help resist pressurization pressures in the bottle of up to
3 bars (3 x 10
5 Pa), including up to 2.5, up to 2, up to 1.5, up to 1, up to 0.5 bars (2.5 x 10
5, 2 x 10
5, 1.5 x 10
5, 1 x 10
5, 0.5 x 10
5 Pa), and up to 0.3 bars (6.3 x 10
5 Pa), including ranges bordered and including the foregoing values. The preform design
also plays a role in resisting pressures such that much higher pressures than already
demonstrated can be resisted with greater strap thickness available from the preform.
The strap design provides a more efficient way of resisting the pressure in a bottle
that also performs well without pressure.
[0014] Embodiments disclosed herein can be utilized in bottle volumes of a wide range. For
example, features and functions disclosed herein can be utilized with a 3 ounce (0.085
liter) bottle up to a multiple gallon bottle. As another example, features and functions
disclosed herein can be utilized with an 8 ounce (0.24 liter/0.15 liter) bottle up
to a 3 liter bottle, including 12 ounces (0.35 liters) to 2 liters, 16 (0.47 liters)
ounces to 1 liter, 18 ounces (0.53 liters) to 0.75 liters, and 0.5 liters, including
ranges bordered and including the foregoing values.

[0033] While the present invention is subject to various modifications and alternative forms,
specific embodiments thereof have been shown by way of example in the drawings and
will herein be described in detail. The invention should be understood to not be limited
to the particular forms disclosed, but on the contrary, the intention is to cover
all modifications, equivalents, and alternatives falling within the scope of the present
invention which is defined by the claims.
DETAILED DISCUSSION
[0034] In the following detailed description, reference is made to the accompanying drawings,
which form a part hereof. In the drawings, similar symbols typically identify similar
components, unless context dictates otherwise. The illustrative embodiments described
in the detailed description and drawings are not meant to be limiting. Other embodiments
may be utilized, and other changes may be made, without departing from the scope of
the invention defined by the claims. It will be readily understood that the aspects
of the present disclosure, as generally discussed herein, and illustrated in the Figures,
may be arranged, substituted, combined, and designed in a wide variety of different
configurations, all of which are explicitly contemplated and made part of this disclosure.
[0035] In particular, disclosed herein are articles, including preforms and containers,
which utilize less plastic in their construction while maintaining or surpassing the
ease of processing and excellent structural properties associated with current commercial
designs.
[0036] Figure 1 illustrates a side view of an embodiment of the bottle 1. The bottle 1 has
a base 24a that extends up into a base rib 22. Connected to the base 24a, the grip
portion 8 comprises a plurality of grip portion ribs 3a (i.e., sidewall ribs). As
illustrated in Figure 1, grip portion ribs 3a (positioned in the grip portion 8) may
vary in depth by separating or transitioning the rib from a deep rib 2a to a flattened
and/or shallow rib 6a to be discussed in further detail below. In the illustrated
embodiment, the grip portion ribs 3a swirl or angulate around the grip portion 8.
[0037] Referring to Figure 1, a label portion 10 is connected to the grip portion 8 and
comprises one or more label panel ribs 20a (i.e., sidewall ribs). The label panel
portion 10 transitions into a shoulder 18, which connects to a bell 16. The bell 16
may include scallops (including as illustrated) or other design features or it may
be smooth and generally unornamented. The bell 16 connects to a neck 14, which connects
to a finish 12. From the label portion 10, the bell 16 leads upward and radially inward,
relative to a central axis 25, to the neck 14 and finish 12. The finish 12 can be
adapted to receive a closure to seal contents in the bottle 1. The finish 12 defines
an opening 11 that leads to an interior of the bottle 1 for containing a beverage
and/or other contents. The interior can be defined as at least one of the finish 12,
the neck 14, the bell 16, the shoulder 18, the label portion 10, the grip portion
8, or the base 24a.
[0038] A substantially vertical wall comprising the grip portion 8 and label portion 10
between the base 24a and bell 16, extending substantially along the central axis 25
to define at least part of the interior of the bottle 1, can be considered a sidewall
of the bottle 1. In some embodiments, the sidewall may include the bell 16, shoulder
18, and/or base 24a. The perimeter (i.e., periphery) of the sidewall is substantially
perpendicular to the central axis 25 of the interior. The sidewall defines at least
part of the interior of the bottle 1. The finish 12, the neck 14, the bell 16, the
shoulder 18, the label portion 10, the grip portion 8, and the base 24a can each define
a respective perimeter or circumference (i.e., periphery) (substantially perpendicular
to the central axis 25) corresponding to that portion. For example, the label portion
10 has a label portion perimeter. As another example, the grip portion 8 has a grip
portion perimeter.
[0039] In the embodiment illustrated in Figure 1, each of the grip portion ribs 3a comprises
a deep rib 2a section transitioning to a middle section 4a then to a flattened and/or
shallow rib 6a sections. As Figure 1 illustrates, each of the label panel ribs 20a
may comprise a deep rib 2b section transitioning to a middle section 4b then to a
flattened and/or shallow rib 6b sections. The deep, middle, and shallow rib sections
may also be called deep, middle, and shallow ribs as shorthand, but it is to be understood
that these terms are meant to define sections of a rib in the grip portion 8, label
portion 10, and base rib 22. A varying depth grip portion rib 3a transitions from
a deep rib 2a section to a middle rib/section 4a then to a flattened and/or shallow
rib 6a section. A varying depth label panel rib 20a transitions from a deep rib 2b
to a middle rib/section 4b then to a flattened and/or shallow rib 6b. The one or more
flattened and/or shallow ribs 6a,b form an equivalent of recessed columns 7a at portions
where a plurality flattened and/or shallow ribs 6a,b substantially vertically line
up along the vertical or central axis 25 of the bottle 1 as illustrated in Figure
1. A plurality of deep ribs 2a,b substantially vertically line up along the vertical
or central axis 25 of the bottle 1 as illustrated in Figure 1.
[0040] In some embodiments, the flattened and/or shallow ribs 6b of the label panel ribs
20a are vertically misaligned with the flattened and/or shallow ribs 6a of the grip
portion ribs 3a such that the label portion 10 has a set of recessed columns and the
grip portion 8 has another set of recessed columns. Thus, the recessed column of the
label portion 10 can be vertically misaligned from the recessed columns of the grip
portion 8. In some embodiments, the bottle 1 can have recessed columns in just the
grip portion 8 or just the label panel portion 10.
[0041] In the illustrated embodiments with three lined-up flattened and/or shallow ribs
6a,b, the bottle respectively has three recessed columns 7a. The three recessed columns
7a may be equally spaced apart around the circumference of the bottle 1 and located
on the opposite side of the bottle circumference from the deep rib 2a,b portions.
With three equally spaced recessed columns 7a, the recessed columns 7a are spaced
every 120 degrees around the bottle 1 circumference. Any number of recessed columns
7a may be incorporated into a design of the bottle 1 by increasing or decreasing the
number of flattened and/or shallow ribs 6a,b that substantially vertically line up
along the vertical or central axis 25. For instance, the bottle may have as few as
1 or up to 10 recessed columns 7a, including 2, 3, 4, 5, 6, 7, 8, or 9 recessed columns
7a, including ranges bordered and including the foregoing values. The collections
of flattened and/or shallow ribs 6a,b that form recessed columns 7a provide resistance
to leaning, load crushing, and/or stretching. Leaning can occur when during and/or
after bottle packaging, a bottle experiences top load forces (tangential forces or
otherwise) from other bottles and/or other objects stacked on top of the bottle. Similarly,
top load crushing can occur due to vertical compression (or otherwise) forces from
bottles and/or other objects stacked on top. Stretching can occur when a bottle is
pressurized. The recessed columns 7a transfer the resulting forces along the wall
to the base 24a and increase bottle 1 rigidity. Deep ribs 2a,b of the grip portion
ribs 3a and label panel ribs 20a provide the hoop strength that can be equivalent
to the hoop strength of normal or non-varying depth ribs. The number of ribs, including
base ribs 22, grip portion ribs 3a, and/or label panel ribs 20a may vary from 1 to
30 ribs every 10 centimeters of any rib containing portion of the bottle, such as,
but not limited to the grip portion 8 and/or label panel portion 10, including 1,
2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18,19, 20, 21, 22, 23, 24,
25, 26, 27, 28, or 29 ribs every 10 centimeters, including ranges bordered and including
the foregoing values. The aforementioned 10 centimeter section that is used to measure
the number of ribs need not be actually 10 centimeters in length. Rather, 10 centimeters
is used illustratively to provide a ratio for the number of ribs.
[0042] While discussed above in reference to Figure 1, as will be apparent, recessed column
features, functions, and variations thereof may be applied to any of the embodiments
discussed in reference to Figures 2-28. For a further discussion of the recessed columns,
refer to
U.S. Patent No. 8,556,098, entitled "Plastic Container Having Sidewall Ribs with Varying Depth".
[0043] With continued reference to Figure 1, the base 24a has a strap rib 40a. The strap
rib 40a has a sidewall end 42a that terminates along the sidewall of the bottle 1
as discussed herein. The base has 24a has a load rib 44a. As illustrated in Figure
1, the base 24a can have two load ribs 44a between two strap ribs 40a. In some embodiments,
the base 24a can have 1, 3, 4, and 5 load ribs 44a between two strap ribs 40a. The
load rib 44a has a sidewall end 43a that terminates along the base 24a near or at
a transition from the base 24a to the sidewall of the bottle 1. As illustrated in
Figure 1, the sidewall end 43a of the load rib 44a may be vertically lower than the
sidewall end 42a of the strap rib 40a along the central axis 25. In some embodiments,
the sidewall end 43a of the load rib 44a may terminate along the sidewall of the bottle
1 at a same height as to the sidewall end 42a of the strap rib 40a. The base 24a has
feet 45a formed between the strap ribs 40a and the load ribs 44a.
[0044] The strap rib 40a is relatively larger and deeper than the load rib 44a as discussed
herein. As illustrated in Figure 1, the strap base rib 40a may vertically align with
the recessed columns 7a. Where a bottle 1 has three recessed columns 7a, the base
24a can have three strap ribs 40a. The strap ribs 40a are spaced equally around the
circumference of the bottle 1. With three equally spaced strap ribs 40a, the strap
ribs 40a are positioned every 120 degrees around the bottle circumference. The load
ribs 44a can vertically align with the grip portion rib 3a sections between the recessed
columns 7a. In some embodiments, the strap ribs 40a may be vertically misaligned with
the recessed columns 7a. In some embodiments, the strap ribs 40a may be spaced unequally
around the bottle circumference. In some embodiments, the base 24a may have more or
less strap ribs 40a than the number of recessed columns 7a.
[0045] Figure 2 illustrates a side view of the embodiment shown in Figure 1 rotated 60 degrees.
The sidewall end 42a of the strap rib 40a vertically aligns or points to substantially
the center of the recessed columns 7a (center point of the shallow and/or flattened
ribs 2a,b). As illustrated in Figure 2, the strap rib 40a forms a recess 46a from
a side view perspective. The recess 46a is relatively a small area in comparison to
feet 45a contact area with a resting surface. A small recess 46a aids in distributing
more resin toward the feet 45a during the blowing process. More resin at the feet
45a increases the abrasion resistance and strength of the feet 45a. Thus, strap ribs
40a can function to provide internal pressure resistance while leaving enough resin
for the feet 45a to achieve the benefits of a flat foot base (i.e., thicker resin
feet 45a for greater abrasion, deformation, and/or stress resistance; and/or greater
foot contact area for stability and load distribution).
[0046] The strap rib 40a can extend substantially from a central portion of the base 24a
(from the central axis 25) as discussed herein. The strap rib 40a can act as a strap
between the recessed columns 7a of the sidewall to the central portion of the base
24a. As shown in Figure 2, the strap rib 40a provides a more direct and shorter path
to the center of the base 24a from the sidewall of the bottle 1 without proceeding
to the vertical level of the feet 45a. As discussed herein, the strap ribs 40a thus
provide a relatively more pressure resistant base 24a. The strap rib 40a provides
a link for forces and stresses between the sidewall, including the recessed column
7a, and the central portion of the base 24a.
[0047] Figure 3 illustrates a side view of an embodiment of a base 24c having six strap
ribs 40c. Three strap ribs 40c can vertically align with recessed columns 7a. The
other three strap ribs 40c can vertically align along the central axis substantially
at the deep ribs 2a,b of the grip portion ribs 3a and the label panel ribs 20a. The
strap ribs 40c are equally spaced around the circumference of the bottle 1. With equally
spaced strap ribs 40c, the strap ribs 40c are positioned every 60 degrees around the
bottle circumference. Under pressure, the deep rib 2a,b sections may flex out, triangulating
the bottle 1. Triangulation of the bottle 1 can occur in the grip portion 8 and/or
label portion 10. The strap ribs 40a vertically aligned with the deep rib 2a,b sections
can at least partially prevent the flexing out of the deep ribs 2a,b. The strap ribs
40a vertically aligned with the deep ribs 2a,b resist outward radial expansion, which
in turn can help prevent outward radial expansion at the grip portion 8 and/or the
label portion 10. Preventing outward radial expansion at the grip portion 8 and/or
the label portion 10 helps prevent triangulation of the bottle 1. Preventing triangulation
helps retain bottle roundness for consumer appeal. Further, maintaining bottle roundness
aids in ensuring a labeler during the bottling process correctly labels the bottle.
The labeler may not be able to properly label a triangulated bottle.
[0048] Figure 4 illustrates a top perspective view of an embodiment of a strap rib 40a.
As shown in Figure 4, the strap rib 40a has a sidewall end 42a that terminates at
substantially the edge or boundary of the base rib 22. The illustrated sidewall end
42a terminating at or near the base rib 22 still allows for the strap rib 40a to communicate
with the recessed column 7a through the base rib 22 as discussed herein. By the strap
rib 40a not proceeding beyond the base rib 22, the base rib 22 is maintained as an
unbroken rib around the perimeter of the bottle 1. As discussed herein, the base rib
22 can act as a contact point with other bottles during packaging, shipping, and/or
handling. An unbroken base rib 22 can better resist stresses and deformation placed
on the bottle when contacted by or bumped against other bottles or structures. Thus,
where retaining contact point integrity is desired, such as for example unpressurized
or relatively low pressurized bottle applications, the base rib 22 can remain unbroken
with the sidewall end 42a of the strap rib 40a terminating at or near the base rib
22.
[0049] Figure 5 illustrates a side view of an embodiment of a base 24b with a strap rib
40b leading into the sidewall of the bottle 1 beyond the base rib 22. As shown in
Figure 5, the sidewall end 42b of the strap rib 40b may terminate in the grip portion
8, such as at a first flattened and/or shallow rib 6a (first from the base 24b) when
the strap rib 40b vertically aligns with the recessed column 7a. In some embodiments,
the strap rib 40b may vertically align with the deep ribs 2a,b and may terminate into
a first deep rib 2a (first from the base 24b). In some embodiments, the strap rib
40b may have a sidewall end 42a that terminates past the first shallow rib 6a and/or
the first deep rib 2a, such as for example at the second, third, and/or third fourth
grip portion ribs 3a.
[0050] Figure 5A illustrates a side view of another embodiment of the bottle 1 comprising
a base 24d, three strap ribs 40d, and six load ribs 44d. The base 24d has feet 45d
formed between the strap ribs 40d and the load ribs 44d. Each of the strap ribs 40d
extends substantially from a central portion of the base 24d and terminates at a sidewall
end 42d in the grip portion 8, as discussed in connection with embodiments illustrated
in Figures 1-2. The strap ribs 40d cooperate with the recessed columns 7a of the sidewall
to resist bending, leaning, crumbling, or stretching along the sidewall and the central
portion of the base 24d. In the embodiment illustrated in Figure 5A, two load ribs
44d are spaced equally between two of the strap ribs 40d. In other embodiments, the
base 24d may have more or less than two of the load ribs 44d positioned between two
of the strap ribs 40d. Each of the load ribs 44d has a sidewall end 43d which terminates
along the base 24d near or at a transition from the base 24d to the sidewall of the
bottle 1. As illustrated in Figure 5A, each of the sidewall ends 43d is vertically
lower than the sidewall ends 42d along the central axis 25. In other embodiments,
however, the sidewall ends 43d of the load rib 44d may terminate along the sidewall
of the bottle 1 at a height along the central axis 25 which is equal to the sidewall
ends 42d of the strap ribs 40d.
[0051] Figure 6 illustrates a side view of an embodiment of a label portion 10 with six
recessed columns 7b. As shown in Figure 6, the label portion 10 may have six shallow
ribs 6b that align vertically. Each vertical alignment of the shallow ribs 6b forms
a recessed column 7b. The recessed columns 7b are equally spaced around the circumference
of the bottle 1. With six equally spaced recessed columns 7b around the bottle circumference,
the recessed column 7b are positioned every 60 degrees around the bottle circumference.
More recessed columns 7b can help prevent triangulation of the bottle 1, including
in the label portion 10, as discussed herein. Shallow ribs 6a,b and/or recessed columns
7a,b better resist radially outward flexing, at least partially because shallower
ribs have less radial depth to provide a range for flexing. Correspondingly, shallow
ribs 6a,b and/or recessed columns 7a,b have better resistance to internal pressure
relative to the deep ribs 2a,b. Thus, more frequent shallow ribs 6a,b and/or recessed
columns 7a,b around the bottle circumference helps inhibit triangulation of the bottle
1. In some embodiments, the six recessed column 7b may be combined with embodiments
illustrated in Figure 3 with six strap ribs 40c. Accordingly, such embodiments may
better resist triangulation in both label portion 10 and the grip portion 8 as discussed
herein. As shown in Figure 6, having three recessed columns 7a in the grip portion
8 with six recessed column 7b in the grip portion 10 helps achieve rigidity in the
grip portion 8 with the three regions of deep ribs 2a providing hoop strength while
avoiding triangulation in the label portion 10 with six recessed columns 7b inhibiting
flexing out of the sidewalls, particularly at the label portion 10.
[0052] Figure 6A illustrates a side view of another embodiment of the bottle 1 comprising
a label portion 10 with six recessed columns 7b equally spaced around the circumference
of the bottle 1. It will be appreciated by those skilled in the art that three of
the recessed columns 7b are aligned with the recessed columns 7a in the grip portion
8 of the bottle 1, and thereby function as extensions of the columns 7a. Furthermore,
the embodiment of the bottle 1 illustrated in Figure 6A is substantially similar to
the embodiment illustrated in Figure 5A, with the exception that the bottle 1 illustrated
in Figure 6A further comprises a base rib 22. Each of the three strap ribs 40d extends
into the sidewall of the bottle 1 beyond the base rib 22, thereby breaking the base
rib 22 into 120-degree segments. It will be apparent to those of ordinary skill that
the numbers of the recessed columns 7a,b, the strap ribs 40d, and the load ribs 44d,
as well as the specific implementation of the base rib 22, may be varied from those
shown herein without deviating from the spirit and scope of the present invention.
[0053] Figure 7 illustrates a top perspective view of an embodiment of a strap rib 40b.
As shown in Figure 7, the strap rib 40b has a sidewall end 42b that terminates substantially
at or in the first shallow rib 6a (first from the base 24b) via a straight portion
45 as discussed herein, and in particular, as discussed in reference to Figure 19.
A sidewall end 42b that proceeds into the grip portion 8 of the bottle, such as into
the grip portion ribs 3a, allows the strap rib 40b to directly connect or communicate
with a recessed column 7a. The direct communication of the strap rib 40b and the recessed
column 7a can help achieve resistance to internal pressure as discussed herein. The
direct communication between the strap rib 40b and the recessed column 7a can help
achieve better transfer and resistance to stresses placed on a bottle as discussed
herein.
[0054] Figure 7A illustrates a top perspective view of an embodiment of the strap rib 40d,
as illustrated in Figure 5A. In the illustrated embodiment of Figure 7A, the strap
rib 40d comprises the straight portion 45 and a sidewall end 42d which terminates
substantially at or in the first shallow rib 6a. As discussed herein, extending the
sidewall ends 42d into the grip portion 8 of the bottle 1, such as into the grip portion
ribs 3a, enables the strap ribs 40d to operate in conjunction with the recessed columns
7a to achieve resistance to internal pressure as discussed herein. The direct communication
between the strap ribs 40d and the recessed columns 7a achieves a better transfer
of, and resistance to, stresses placed on a bottle as discussed herein.
[0055] Figures 8A and 8B illustrate a bottom perspective view of embodiments of the bottle
1 with columns in the sidewalls. As shown in Figure 8A, the bottle 1 may have a protruding
column 47a,b. A protruding column may be considered a column that radially protrudes
outward from an immediately surrounding surface formed by, for example, the sidewall
of the bottle 1. The protruding column has a grip portion 8 (including the base rib
22) protruding column 47a and a label portion 10 protruding column 47b. The protruding
column 47a,b can resist bending, leaning, and/or stretching as discussed herein. The
protruding column 47a,b can also resist radially outward flexing at and near the protruding
column 47a,b. The protruding column 47a,b is formed substantially along the entire
length or height of the bottle sidewall without breaking the continuity of other bottle
contact points of the bottle as discussed herein, such as, for example, at or near
the base rib 22. As shown in Figure 8A, the base 24a has a strap rib 40a that substantially
vertically aligns with the protruding column 47a,b. The alignment of the protruding
column 47a,b with the strap rib 40a achieves substantially the same resistance to
bending, leaning, stretching, and/or base rollout as discussed herein in reference
to the base rib 40a vertically aligning with a recessed column 7a.
[0056] As shown in Figure 8B, the bottle 1 may have an indented column 49. An indented column
may be considered a column that radially indents inwardly from an immediately surrounding
surface formed by, for example, the sidewall of the bottle 1. The indented column
40 is positioned in the grip portion 8 (including the base rib 22). The indented column
49 can resist bending, leaning, and/or stretching as discussed herein. The indented
column 49 can also resist radially outward flexing at and near the indented column
49. The indented column 49 can achieve the desired function discussed herein while
avoiding protruding from a perimeter of the sidewall of the bottle 1. The indented
column 49 can project through, for example, the base rib 22, making the base rib 22
discontinuous. A discontinuous rib 22 can be utilized in pressurized bottle applications
where at least some of the contact point resistance as discussed herein is provided
due the bottle being pressurized. As shown in Figure 8A, the base 24b has a strap
rib 40b that substantially vertically aligns with the intended column 49. The strap
rib 40b transitions into the indented column 49 continuously for potentially better
functionality. The strap rib 40b can directly communicate with the indented column
49 by the strap rib 40b directly transitioning into the indented column 49, through,
for example, the base rib 22 as illustrated in Figure 8B. The alignment and direct
communication of the strap rib 40b with the indented column 49 helps form a pressure
resistance strap as discussed herein, and in particular, in reference to Figures 16,
17, and 25. The alignment and direct communication of the indented column 49 with
the strap rib 40b achieves substantially the same resistance to bending, leaning,
stretching, and/or base rollout as discussed herein in reference to the base rib 40b
vertically aligning with a recessed column 7a.
[0057] Figure 9 illustrates a bottom perspective view of an embodiment of the base 24a.
The base 24a has a strap rib 40a and a load rib 44a as discussed herein. The base
24a has a gate 52. As shown in Figure 9, the base 24a may have a dome 54. The dome
54 may be considered the area generally or immediately around the gate 52. The dome
54 may be termed as a push up of the base 24a. For example, the dome 54 is a wall
of the base 24a that slopes more steeply toward a resting surface when the bottle
is vertically placed on the resting surface relative to the rest of the wall of the
base 24a leading to legs the 45a of the base 24a.
[0058] The strap rib 40a has a base end 56a that terminates near, at, or in the dome 54.
In some embodiments, the base end 56a for a strap rib 40a can be positioned outside
of the dome 54 region similarly to base ends 58a for load ribs 44a. The strap rib
40a has a petal side wall (i.e., rib side or valley wall) 48a that connects that strap
rib 40a to portions of the base 24a and the feet 45a of the base 24a. The rib side
wall 48a smoothly and gradually transitions into the base 24a and the feet 45a. The
smooth and gradual transition provides internal pressure resistance at and near the
rib side wall 48a since more spherical features of the bottle 1 can better accommodate
internal pressure. The strap rib 40a is relatively deeper in the base 24a than the
load rib 58a to provide stress transfer and pressure resistance as discussed herein.
[0059] The load rib 44a has a base end 58a that terminates at, near, or at the dome 54.
As shown in Figure 9, the base end 58a of the load rib 44a may terminate before the
base end 56a of the strap rib 40a. The load rib 44a is shallow relative to the strap
rib 40a. As show in Figure 9, the load rib 44a may not have or may have a smaller
rib side wall 48a feature as discussed herein reference to the strap rib 40a. The
transition from the load rib 44a to the base 24a and the feet 45a is more abrupt or
sharper. The sharper transition provides external stress resistance relative to a
shallow rib side 48a. When the bottle 1 is top loaded during packaging, shipping,
and/or handling, sharper transitions of the load ribs 44a help resist bending and/or
leaning as discussed herein by, for example, maintaining the integrity and shape of
the base 24a.
[0060] The sharper transitions provide for faster transitions into the feet 45a of the base
24a. Faster transitions lead to more area of the base 24a being available for relatively
larger feet 45a. Larger feet 45a of a flat foot base 24a as discussed herein and as
illustrated in Figure 9 provide more resin contact area with a resting surface. More
resin contacting the resting surface provides better abrasion resistance and stability
of the base 24a.
[0061] As shown in Figure 9, the rib side wall 48a may transition into the strap rib 40a
itself more abruptly or sharply relative to the transition from the wall 48a to the
feet 45a. The sharper transitions at the strap rib 40a itself may provide more rigidity
to the strap rib 40a to resist or inhibit flexing due to internal pressures as discussed
herein.
[0062] Figure 10 illustrates a bottom perspective view of an embodiment of the base 24b.
The base 24b has a strap rib 40b and a load rib 44b as discussed herein. The strap
rib 40b has a base end 56b that terminates near, at, or in the dome 54. As shown in
Figure 10, the base end 56b of the strap rib 40b may terminate substantially near
or at the gate 52. The load rib 44b has a base end 58b that terminates near, at, or
in the dome 54. As shown in Figure 10, the base end 58b of the load rib 44b may terminate
before the base end 56b of the strap rib 40b. Terminating the base ends 56b of the
strap rib 40b and/or the base end 58b of the load rib 44b substantially near or at
the gate 52 can provide more internal pressure resistance to the base 24b as discussed
herein, helping prevent, for example, base 24b rollout. Terminating the base ends
56b of the strap rib 40b substantially near or at the gate 52 provides a strap rib
40b that is continuous from (or near) the gate 52 to the sidewall end 42b. As shown
in Figure 7 and Figure 10, the sidewall end 42b may terminate at the first shallow
rib 6a and communicate directly with a recessed column 7a. The continuity from the
recessed column 7a to the gate 52 provides a substantially continuous pressure resistance
band or strap from a top of the label portion 10 to the gate 52. A pressure resistance
strap 9a,b (Figures 16 and 17) that is substantially continuous can provide greater
resistance to internal pressure as discussed herein.
[0063] Figure 11 illustrates a bottom perspective view of an embodiment of the base 24c.
The base 24c has a strap rib 40c and a load rib 44c as discussed herein. As shown
in Figure 11, the base 24c does not have a dome. The walls of the base 24c radially
extend directly from the gate 52. Not having a dome helps prevent puddle formation
of resin near the gate 52. Avoiding puddle formation can reduce wasted resin. As shown
in Figure 11, without a dome 54, the strap rib 40c can extend directly or nearly continuously
to the gate 52. The strap rib 40c can terminate near or at the gate 52 with a smooth
transition into the wall near the gate 52 or the gate itself 52. The smooth transitions
from the gate 52, the wall around the gate 52, the base end 43c, and/or strap rib
40c create a more uniform wall or surface of the base 24c, particularly around the
gate 52 where a majority of the flexing due to base rollout occurs. The more uniform
wall feature is better able to resist internal pressure as discussed herein, and in
particular, resistance to bottle stretching and base rollout. The resistance to internal
pressure is further enhanced by providing six strap ribs 43c that inhibit base 24c
rollout. With more strap ribs 40c resisting internal pressure, the less likely the
base 24c is to rollout under increased pressure. Further, more of the base 24c is
formed by the rib side walls 48c, which increases internal pressure resistance due
to an increased surface area being provided by a spherical surface of the rib side
walls 48c as discussed herein.
[0064] Figure 11A illustrates a bottom perspective view of an embodiment of the base 24d,
as illustrated in Figure 5A. The base 24d comprises the strap ribs 40d and the load
ribs 44d as discussed herein. The base 24d shown in Figure 11A further comprises the
gate 52 and the dome 54. The walls of the base 24d radially extend directly from the
gate 52. Each of the strap ribs 40d has a base end 56d which terminates in the dome
54, near the periphery of the gate 52. In other embodiments, the base ends 56d may
terminate near or at the periphery of the dome 54. In still other embodiments, the
base ends 56d may be positioned outside of the dome 54 region, similarly to base ends
58d of the load ribs 44d. Each of the strap ribs 40d has two rib side walls (i.e.,
valley walls) 48d that connect the strap rib 40d to portions of the base 24d and the
feet 45d. Each of the rib side walls 48d smoothly and gradually transitions into the
base 24d and the feet 45d. The smooth and gradual transitions provide internal pressure
resistance at and near the rib side walls 48d since more spherical features of the
bottle 1 can better accommodate internal pressure. The strap ribs 40d are relatively
deeper in the base 24d than the load ribs 44d to provide stress transfer and pressure
resistance as discussed herein.
[0065] As mentioned above, each of the load ribs 44d comprises a base end 58d which terminates
at, near, or within the dome 54. As shown in the embodiment of Figure 11A, the base
ends 58d of the load ribs 44d terminate before the base ends 56d of the strap ribs
40d. The load ribs 44d are shallow relative to the strap ribs 40d. As further shown
in Figure 11A, the load ribs 44d have a smaller rib side wall 48d feature as discussed
with reference to the strap ribs 40d. Thus, the transition from each of the load ribs
44d to the feet 45d of the base 24d is more abrupt or sharper, thereby providing greater
external stress resistance than possible with a larger rib side wall 48d feature.
As will be appreciated by those skilled in the art, sharper transitions of the load
ribs 44d helps resist bending and/or leaning as discussed herein by, for example,
maintaining the integrity and shape of the base 24d when the bottle 1 is top loaded
during packaging, shipping, and/or handling.
[0066] Figures 12-15 illustrate bottom views of embodiments of the various bases discussed
herein. Figures 12-14 show a series of bases that illustrate a gradual progression
of some of the base ends 56a-d, 58a-d closer toward the gate 52. For example, as discussed
herein, the base end 56b of the load rib 40b is closer to the gate 52 in the dome
54 than the base end 56a of the load rib 40a. As another example, as discussed herein,
the base end 58b of the load rib 44b is closer to the gate 52 in the dome 54 than
the base end 58a of the load rib 44a. As shown, in Figure 12 and 13, the base ends
58a,b of the load ribs 44a,b may be radially further away from the gate 52 than the
base ends 56a,b of the strap ribs 40a,b. As shown in Figure 14, the base ends 58d
of the load ribs 44d may be radially equidistant from the gate 52 with the base ends
56d of the strap ribs 40d. In some embodiments, a closer proximity of the base ends
56a,b,c,d of the strap ribs 40a,b,c,d to the gate 52 may provide better internal pressure
resistance, as discussed herein. In some embodiments, a closer proximity of the base
ends 58a,b,c,d of the load ribs 44a,b,c,d to the gate 52 may provide further better
internal pressure resistance as discussed herein, although the primary internal pressure
resistance is still provided by the strap ribs 40a,b,c,d. The base ends 58a,b,c,d
of the load ribs 44a,b,c,d extending closer to the gate 52 with the base ends 56a,b,c,d
of the strap ribs 40a,b,c,d may complement the pressure resistance provided by the
strap ribs 40a,b,c,d.
[0067] As shown in Figure 15, an embodiment of the base 24c without a dome 54c forms a more
uniform wall around the gate 52. The strap ribs 40c can be a more smooth or continuous
extension from or around the gate 52. The continuous extension from or around the
gate 52 helps form a pressure resistance strap 9c (Figure 17) that extends from the
gate 52 to a top of the label portion 10. The continuous pressure resistance strap
9c is better able to resist internal pressure as discussed herein, and in particular,
resistance to bottle stretching and base rollout.
[0068] Figure 16A illustrates a cross-section along the central axis 25 of an embodiment
of the bottle 1 as illustrated in Figure 2. As shown in Figure 16A, the flat rib or
recessed column 7a is located on the opposite side of the bottle circumference of
the deep rib 2a,b portions (with, for example, an embodiment having three recessed
columns 7a). In the illustrated embodiment, the base rib 22 has a constant cross-section
throughout the circumference of the bottle 1. In some embodiments, the diameter Ld
of the base 24 is larger by 0.5 to 2 millimeters, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2,
1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9 millimeters, including ranges bordered and including
the foregoing values, than any other diameter of the bottle 1. In an embodiment with
the largest diameter of the bottle 1 being Ld, the bottle 1 has a single point of
contact at just the base 24a with other substantially similar bottles in a production
line and/or packaging. Further, a larger base 24a diameter Ld may improve stability
when there is any damage to the base 24a. As shown in Figure 16A, the diameter Ls
at the shoulder 18 may be equal to the diameter Ld, which provides for two points
of contact, at the shoulder 18 and base 24a, with other substantially similar bottles
in a production line and/or packaging. In some embodiments, the diameter(s) in any
portion of the bottle 1 varies, where the largest diameters create points of contact
in a production line and/or packaging. The bottles may have either a single point
of contact or multiple points of contact.
[0069] As shown in Figure 16A, a strap rib 40a may vertically align with a recessed column
7a. The strap rib 40a and recessed column 7a in combination can form a pressure resistance
band 9a that substantially extends from the gate 52 to a top portion of the label
portion 10 or a top portion of the recessed column 7a. The pressure resistance band
9a provides resistance against internal pressure substantially for the base 24a and
sidewall of the bottle 1 to, for example, inhibit stretching and/or base rollout as
discussed herein.
[0070] Figure 16B and 16C illustrate embodiments where the deep rib 2a,b is a depth that
is larger than a depth of the middle rib 4a,b which is larger than a depth of the
flattened and/or shallow rib 6a,b. The transition between the varying depths is smooth
as depicted in Figures 1A. In some embodiments, the transition may be some other form
such as a step change connecting the varying depth portions or sections. In the illustrated
embodiments, a grip portion rib 3a (i.e., sidewall ribs) has three deep rib 2a portions,
six middle rib 4a portions, and three flattened and/or shallow rib 6a portions. As
disclosed herein, the term "portions" can be equivalent to the term "sections" in
reference to varying depth ribs.
[0071] Referring to Figure 16B, an embodiment showing a cross-section of the bottle 1, looking
down the vertical or central axis 25, illustrates a cross-section of a grip portion
rib 3a. As disclosed herein, the term "vertical axis" can be equivalent of the term
"central axis". The depth of the grip portion rib 3a varies from deep ribs 2a to flattened
and/or shallow ribs 6a. The one or more flattened and/or shallow ribs 6a form an equivalent
of recessed columns 7a at portions where a plurality flattened and/or shallow ribs
6a substantially vertically line up along the vertical or central axis 25 of the bottle
1 as illustrated in Figures 1 and 2. A plurality of deep ribs 2a substantially vertically
line up along the vertical or central axis 25 of the bottle 1 as illustrated in Figures
1 and 2. A plurality of middle ribs 4a substantially vertically line up along the
vertical or central axis 25 of the bottle 1 as illustrated in Figures 1 and 2.
[0072] In the illustrated embodiment with three lined-up flattened and/or shallow rib 6a
portion, the bottle 1 respectively has three recessed columns 7a. The three recessed
columns 7a are equally spaced apart around the circumference of the bottle and located
on the opposite side of the bottle circumference from the deep rib 2a portions. However,
the flattened and/or shallow ribs 6a may be unequally spaced apart around the circumference
of the bottle 1. Further, any number of recessed columns 7a may be incorporated into
a design of the bottle 1 by increasing or decreasing the number of flattened and/or
shallow ribs 6a that substantially vertically line up along the vertical or central
axis 25. For instance, the bottle may have as few as 1 or up to 10 recessed columns
7a, including 2, 3, 4, 5, 6, 7, 8, or 9 recessed columns 7, including ranges bordered
and including the foregoing values. In the illustrated embodiment, the collections
of flattened and/or shallow ribs 6a that form recessed columns 7a provide resistance
to leaning, and/or load crushing, and/or stretching. Leaning can occur when during
and/or after bottle packaging, a bottle experiences top load forces (tangential forces
or otherwise) from other bottles and/or other objects stacked on top of the bottle.
Similarly, top load crushing can occur due to vertical compression (or otherwise)
forces from bottles and/or other objects stacked on top. Stretching can occur when
a bottle is pressurized. In the illustrated embodiment, the recessed columns 7a transfer
the resulting tangential or compression forces along the wall to the base 24a and
increase bottle 1 rigidity. Deep ribs 2a of the grip label rib 3a provide the hoop
strength that can be equivalent to the hoop strength of normal depth ribs. As with
the flattened and/or shallow rib 6a portions, the deep rib 2a portions may vary from
1 to 10 in number on the grip panel ribs 3a, including 2, 3, 4, 5, 6, 7, 8, or 9 deep
rib 2 portions, including ranges bordered and including the foregoing values.
[0073] As Figure 16B illustrates, certain embodiments may minimize the triangle-shaped or
flattened and/or shallow ribs 6a to 20-30%, including 21, 22, 23, 24, 25, 26, 27,
28, or 29%, of the bottle circumference, resulting in a respective 70-80%, including
71, 72, 73, 74, 75, 76, 77, 78, or 79%, of the bottle circumference being trapezoid-shaped
or deep ribs 2a and middle ribs 4a, including ranges bordered and including the foregoing
values. However, any ratio of triangle-shaped to trapezoidal ribs, or other shapes
known in the art, may be utilized.
[0074] Referring to Figure 16B, an embodiment showing a cross-section of the bottle 1, looking
down the vertical or central axis 25, illustrates a cross-section of a label panel
rib 20a (i.e., sidewall ribs). The depth of the label panel rib 20a varies from deep
ribs 2b to flattened and/or shallow ribs 6b. The one or more flattened and/or shallow
ribs 6b form an equivalent of recessed columns 7a at portions where a plurality flattened
and/or shallow ribs 6b substantially vertically line up along the vertical or central
axis 25 of the bottle 1 as illustrated in Figures 1 and 2. The recessed columns 7a
can include one or more flattened and/or shallow ribs 6a of the grip portion 8 as
discussed herein. A plurality of deep ribs 2b substantially vertically line up along
the vertical or central axis 25 of the bottle 1 as illustrated in Figures 1 and 2.
A plurality of middle ribs 4b substantially vertically line up along the vertical
or central axis 25 of the bottle 1 as illustrated in Figures 1 and 2.
[0075] In the illustrated embodiment, with three lined-up flattened and/or shallow rib 6b
portions, the bottle 1 respectively has three recessed columns 7a. The flattened and/or
shallow ribs 6b of the label panel ribs 20a can vertically line up along the vertical
or central axis 25 with the flattened and/or shallow ribs 6a of the grip portion ribs
3a to form the three recessed columns 7a. Thus, in some embodiments, the recessed
columns 7a can extend along a majority or substantial entirety of the sidewall (e.g.,
height and/or length) of the bottle 1 as, for example, illustrated in Figure 1.
[0076] In some embodiments, the flattened and/or shallow ribs 6b of the label panel ribs
20a are vertically misaligned with the flattened and/or shallow ribs 6a of the grip
portion ribs 3a such that the label portion 10 has a set of recessed columns and the
grip portion 8 has another set of recessed columns. Thus, the recessed column of the
label portion 10 can be vertically misaligned from the recessed columns of the grip
portion 8.
[0077] The plurality of deep ribs 2b of the label portion 10 can substantially vertically
line up along the vertical or central axis 25 with the plurality of deep ribs 2a of
the grip portion 8 as illustrated in Figures 1 and 2. In some embodiments, the plurality
of deep ribs 2b of the label portion 10 can be vertically misaligned with the plurality
of deep ribs 2a of the grip portion 8. The plurality of middle ribs 4b label portion
10 can substantially vertically line up along the vertical or central axis 25 with
the middle ribs 4a of the grip portion 8 as illustrated in Figures 1 and 2. In some
embodiments, the plurality of middle ribs 4b label portion 10 can be vertically misaligned
with the middle ribs 4a of the grip portion 8.
[0078] In the illustrated embodiment, the three recessed columns 7a are equally spaced apart
around the circumference of the bottle and located on the opposite side of the bottle
circumference from the deep rib 2b portions. However, the flattened and/or shallow
ribs 6a,b may be unequally spaced apart around the circumference of the bottle 1.
Further, any number of recessed columns 7a may be incorporated into a design of the
bottle 1 by increasing or decreasing the number of flattened and/or shallow ribs 6a,b
that substantially vertically line up along the vertical or central axis 25. For instance,
the bottle 1 may have as few as 1 or up to 10 recessed columns 7a, including 2, 3,
4, 5, 6, 7, 8, or 9 recessed columns 7a, including ranges bordered and including the
foregoing values. In the illustrated embodiment, the collections of flattened and/or
shallow ribs 6b that form recessed columns 7a provide resistance to leaning, load
crushing, and/or stretching as discussed herein. In the illustrated embodiment, the
recessed columns 7a transfer the resulting tangential or compression forces along
the wall to the base 24a and increase bottle 1 rigidity. Deep ribs 2b of the label
panel rib 20a provide the hoop strength that can be equivalent to the hoop strength
of normal depth ribs. As with the flattened and/or shallow rib 6b portions, the deep
rib 2b portions may vary from 1 to 10 in number on the label panel rib 20a, including
2, 3, 4, 5, 6, 7, 8, or 9 deep rib 2b portions, including ranges bordered and including
the foregoing values.
[0079] A depth Dd of a deep rib 2a may vary from 1 to 10 millimeters, including 1.1, 1.2,
1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, or 2.9
millimeters, or 1 to 9, 1 to 7, 1 to 5, or 1 to 3 millimeters, including ranges bordered
and including the foregoing values.
[0080] A depth DL of label panel rib 20a (i.e., deep rib 2b) may vary from 0.5 to 10 millimeters,
including 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1,
2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.9,
4, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, or 4.9 millimeters, 0.5 to 9, 0.5 to 7,
0.5 to 5, or 0.5 to 3 millimeters, including ranges bordered and including the foregoing
values.
[0081] A depth Dm of a middle rib 4a may vary from 0 to 5 millimeters, including 0.1, 0.2,
0.3, 0.4,0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9,
2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7,
3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, or 4.9 millimeters, including
ranges bordered and including the foregoing values. The ratio of Dd of the deep ribs
2a to the Dm of middle ribs 4a may vary from 1:1 to 20:1, including 2:1, 3:1, 4:1,
5:1, 6:1, 7:1, 8:1, 9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1, 18:1, or
19:1, including ranges bordered and including the foregoing values.
[0082] A depth Df of a shallow rib 6a may vary from 0 to 2.5 millimeters, including 0.1,
0.2, 0. 3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8,
1.9, 2, 2.1, 2.2, 2.3, or 2.4 millimeters, including ranges bordered and including
the foregoing values. The ratio of Dd of the deep ribs 2a to the Df of the flattened
and/or shallow ribs 6a may vary from 1:1 to 100:1, including 2:1, 3:1, 4:1, 5:1, 6:1,
7:1, 8:1, 9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1, 18:1, 19:1, 20:1, 21:1,
22:1, 23:1, 24:1, 25:1, 26:1,27:1,28:1, or 29:1, or 1:1 to 90:1, 1:1 to 80:1, 1:1
to 70:1, 1:1 to 60:1, 1:1 to 50:1, 1:1 to 40:1, 1:1 to 30:1 or 1:1 to 20:1, including
ranges bordered and including the foregoing values, including where Df is zero, resulting
in an infinite ratio. The ratio of Dm of the middle ribs 4a to the Df of the flattened
and/or shallow ribs 6a may vary from 1:1 to 50:1, including 2:1, 3:1, 4:1, 5:1, 6:1,
7:1, 8:1, 9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1, 18:1, 19:1, 20:1, 21:1,
22:1, 23:1, or 24:1 or 1:1 to 40:1, 1:1 to 30:1, or 1:1 to 20:1, including ranges
bordered and including the foregoing values, including where Df is zero, resulting
in an infinite ratio.
[0083] A depth Ds of a flattened and/or shallow rib 6b may vary from 0 to 2.5 millimeters,
including 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5,
1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, or 2.4 millimeters, including ranges bordered
and including the foregoing values. The ratio of Dd of the deep ribs 2a to the Ds
of the flattened and/or shallow ribs 6b may vary from 1:1 to 100:1, including 2:1,
3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1,
18:1, 19:1, 20:1, 21:1, 22:1, 23:1, 24:1, 25:1, 26:1, 27:1, 28:1, or 29:1, or 1:1
to 90:1, 1:1 to 80:1, 1:1 to 70:1, 1:1 to 60:1, 1:1 to 50:1, 1:1 to 40:1, 1:1 to 30:1
or 1:1 to 20:1, including ranges bordered and including the foregoing values, including
where Ds is zero, resulting in an infinite ratio. The ratio of DL of the deep ribs
2b to the Ds of the flattened and/or shallow ribs 6b may vary from 1:1 to 100:1, including

values, including where Ds is zero, resulting in an infinite ratio. The ratio of DL
of the deep ribs 2b to the Ds of the flattened and/or shallow ribs 6b may vary from
1:1 to 100:1, including 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, 11:1, 12:1,

[0084] Figure 17 illustrates a cross-section along the central axis 25 of an embodiment
of the bottle 1 as illustrated in Figure 3. As shown in Figure 17, the flat rib or
recessed column 7a is located on the opposite side of the bottle circumference of
the deep rib 2a portions (with, for example, an embodiment having three recessed columns
7a). In the illustrated embodiment, the base rib 22 has a constant cross-section throughout
the circumference of the bottle 1. The features and function of various diameters,
including Ld and Ls, can be utilized as discussed herein.
[0085] As shown in Figure 17, a strap rib 40c may vertically align with a recessed column
7a. Another strap rib 40c may vertically align with the deep rib 2a,b portions. In
the illustrated embodiment, the two strap ribs 40c and recessed column 7a in combination
can form a pressure resistance band 9c that substantially extends from the base rib
22 near the deep ribs 2a, through the gate 52, and to a top portion of the label portion
10 or a top portion of the recessed column 7a. The pressure resistance band 9c provides
resistance against internal pressure substantially continuously through the base 24c
to the sidewall of the bottle 1 to, for example, inhibit stretching and base rollout
as discussed herein. In some embodiments, the other strap rib 40c may vertically align
another recessed column 7a where, for example, the bottle 1 has six recessed columns
7a. A pressure resistance band may be formed by the combination of two recessed columns
and two strap ribs. The pressure resistance band may extend from a top portion of
the label portion 10 on one side of the bottle 1, down the sidewall on the one side
of the bottle 1 and through the gate 52, up the sidewall on the other side of the
bottle 1 to a top portion of the label portion 10 on the other side of the bottle
1 to provide pressure resistance as discussed here and substantially continuously
through a longitudinal perimeter of the bottle 1 (along the central axis 25 at the
sidewalls and through the central axis at the base 24c). For example, Figure 25 illustrates
such an embodiment.
[0086] Figure 18 illustrates a cross-section along the central axis 25 of an embodiment
of the base 24a as illustrated in Figure 16A. As shown in Figure 18, the base 24a
has a strap rib 40a that begins from the base end 56a with a positive slope upward
(relative to a resting surface of the base 24a of the bottle 1) at an angle θ1a toward
the sidewall of the bottle 1. Stated differently, the strap rib 40a does not proceed
toward or get closer to the resting surface from the base end 56a surface before proceeding
upwardly to connect to the sidewall of the bottle 1. The immediate or near immediate
upward/positive slope at the angle θ1a of the strap rib 40a relative to the resting
surface toward the sidewall of the bottle 1 helps inhibit flexing of the gate 52 and
dome 54 due to internal pressures. The upward/positive slope at the angle θ1a combined
with a connection to a sidewall of the bottle 1 at the sidewall end 42a as discussed
herein further helps inhibit flexing of the gate 52 and dome 54 due to internal pressures.
In some embodiments, the angle θ1a may initially be zero and positively increase along
radius R1a as the strap rib proceeds away from the base end 56a toward the sidewall
end 42a. In some embodiments, the larger the angle θ1a is starting from the base end
56a, the larger the pressure resistance will be. In some embodiments, angle θ1a may
vary from 0 to 60 degrees, including 5 to 50, 10 to 55, 15 to 50, 20 to 45, 25 to
35, 20 to 30, including up to 45, up to 40, up to 35, up to 30, up to 25, and up to
20, including ranges bordered and including the foregoing values. In some embodiments,
the angle θ1a may initially be negative from the base end 56a with a radius (curve)
of the strap rib 40a curving the strap rib 40a toward the sidewall end 42a as discussed
herein without departing from the scope of the features and functions disclosed herein.
[0087] The strap rib 40a extends from the base end 56a to the sidewall end 42a along one
or more radii. As shown in Figure 18, the strap rib 40a may extend from the base end
56a with a radius R1a and transition to a radius R2a to terminate at the sidewall
end 42a near or at the base rib 22. In some embodiments, the radius R1a may vary from
20 to 80 millimeters, including 25 to 75, 30 to 65, 35 to 60, 40 to 55, and including
50 millimeters, including ranges bordered and including the foregoing values, where
for example, the diameter (Ld and/or Ls) of the bottle 1 may vary from 30 to 200 millimeters,
including 30 to 40, 30 to 50, 40 to 60, 50 to 70, 60 to 80, 40 to 190, 50 to 180,
60 to 170, 70 to 160, 80 to 150, 90 to 140, 100 to 130, and 110 to 120 millimeters,
including ranges bordered and including the foregoing values. The ratio of radius
R1 a to bottle diameter can vary from 8:1 to 1:10, including 7:1, 6:1, 5:1, 4:1, 3:1,
2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8 and 1:9, including ranges bordered and
including the foregoing values. In some embodiments, the radius R2a may vary from
1 to 25 millimeters, including 5 to 10, 5 to 20, 5 to 10, 1 to 10, 1 to 5, and 10
to 20 millimeters, including ranges bordered and including the foregoing values, where
for example, the diameter (Ld and/or Ls) of the bottle 1 may vary from 30 to 200 millimeters,
including 30 to 40, 30 to 50, 40 to 60, 50 to 70, 60 to 80, 40 to 190, 50 to 180,
60 to 170, 70 to 160, 80 to 150, 90 to 140, 100 to 130, and 110 to 120 millimeters,
including ranges bordered and including the foregoing values. The ratio of radius
R2a to bottle diameter can vary from 1:1 to 1:200, including 1:10, 1:20, 1:30, 1:40,
1:50, 1:60, 1:70, 1:80, 1:90, 1:100, 1:120, 1:130, 1:140, 1:150, 1:160, 1:170, 1:180,
1:190, including ranges bordered and including the foregoing values. The above ranges
and/or ratios are provided as examples. In some embodiments, the radii of the strap
rib 40a and/or diameter of the bottle or other types of containers may exceed the
above stated ranges and/or ratios, such as, for example, in barrel-type containers.
[0088] In some embodiments, the radius R1a and/or radius R2a are relatively large or infinite.
Stated differently, the strap rib 40a can be straight or nearly straight from the
base end 56a to the sidewall end 42a. A straight strap rib can resist more pressure.
Providing a curvature with one or more radii to the strap rib can improve the blowing
process to help prevent poorly blown bottles, which may reduce pressure resistance.
In some embodiments, the strap rib 40a is a combination of curved and straight portions,
such as, for example, as discussed in reference to Figure 19.
[0089] In some embodiments, a transition 41a from radius R1a to radius R2a (or more than
one transition with a strap rib having more than two radii) can occur anywhere along
the strap rib 40a. As show in Figure 18, the transition 41a from radius R1a to radius
R2a may occur at height H1a. In some embodiments, the height H1a may vary from 5 to
30 millimeters, including 10 to 25 and 15 to 20, including ranges bordered and including
the foregoing values, where for example, the height of the bottle 1 may vary from
65 to 300 millimeters, including 80 to 290, 90 to 270, 100 to 260, 110 to 250, 120
to 240, 130 to 230, 140 to 220, 150 to 210, 160 to 200, 170 to 190, including ranges
bordered and including the foregoing values. The ratio of height H1a to bottle height
can vary from 1:3 to 1:60, including 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, 1:11, 1:12,
1:13, 1:14, 1:15, 1:20, 1:25, 1:30, 1:40, 1:45, 1:50, and 1:55, including ranges bordered
and including the foregoing values. The above ranges and/or ratios are provided as
examples. In some embodiments, height H1a and/or height of the bottle or other types
of containers may exceed the above stated ranges and/or ratios, such as, for example,
in barrel-type containers.
[0090] Figure 19 illustrates a cross-section along the central axis 25 of an embodiment
of the base 24b as illustrated in Figure 17. As shown in Figure 19, the base 24b has
a strap rib 40b that begins from the sidewall end 56b with a positive slope upward
(relative to a resting surface of the base 24a of the bottle 1) at an angle θ1b toward
the sidewall of the bottle 1. Stated differently, the strap rib 40a does not proceed
toward or get closer to the resting surface before proceeding upwardly to connect
to the sidewall of the bottle 1. The immediate or near immediate upward/positive slope
at the angle θ1b of the strap rib 40a relative to the resting surface toward the sidewall
of the bottle 1 helps inhibit flexing of the gate 52 and dome 54 due to internal pressures.
The upward/positive slope at the angle θ1b combined with a connection to a sidewall
of the bottle 1 at the sidewall end 42b as discussed herein further helps inhibit
flexing of the gate 52 and dome 54 due to internal pressures. In some embodiments,
the angle θ1b may initially be zero and positively increase along radius R1b as the
strap rib proceeds away from the base end 56b toward the sidewall end 42b. In some
embodiments, the larger the angle θ1b is starting from the base end 56b, the larger
the pressure resistance will be. In some embodiments, angle θ1b may vary from 0 to
60 degrees, including 5 to 50, 10 to 55, 15 to 50, 20 to 45, 25 to 35, 20 to 30, including
up to 45, up to 40, up to 35, up to 30, up to 25, and up to 20, including ranges bordered
and including the foregoing values. In some embodiments, the angle θ1b may initially
be negative from the base end 56b with a radius (curve) of the strap rib 40b curving
the strap rib 40b toward the sidewall end as discussed herein without departing from
the scope of the features and functions disclosed herein.
[0091] The strap rib 40b extends from the base end 56b to the sidewall end 42b along one
or more radii. As shown in Figure 19, the strap rib 40b may extend from the base end
56b with a radius R1b and a transition 41b to a radius R2b through the base rib 22,
followed by a transition to a straight portion 45 to terminate at the sidewall end
42b near, at, in the first shallow rib 6a as discussed herein . In some embodiments,
the radius R1b may vary from 20 to 85 millimeters, including 25 to 80, 30 to 70, 35
to 65, 40 to 60, 45 to 55 and including 50 millimeters, including ranges bordered
and including the foregoing values, where for example, the diameter (Ld and/or Ls)
of the bottle 1 may vary from 30 to 200 millimeters, including 30 to 40, 30 to 50,
40 to 60, 50 to 70, 60 to 80, 40 to 190, 50 to 180, 60 to 170, 70 to 160, 80 to 150,
90 to 140, 100 to 130, and 110 to 120 millimeters, including ranges bordered and including
the foregoing values. The ratio of radius R1b to bottle diameter can vary from 9:1
to 1:10, including 8:1, 7:1, 6:1, 5:1, 4:1, 3:1, 2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6,
1:7, 1:8 and 1:9, including ranges bordered and including the foregoing values. In
some embodiments, the radius R2b may vary from 0 to 30 millimeters, including 5 to
25, 5 to 20, 5 to 10, 1 to 10, and 10 to 20 millimeters, including ranges bordered
and including the foregoing values, where for example, the diameter (Ld and/or Ls)
of the bottle 1 may vary from 30 to 200 millimeters, including 30 to 40, 30 to 50,
40 to 60, 50 to 70, 60 to 80, 40 to 190, 50 to 180, 60 to 170, 70 to 160, 80 to 150,
90 to 140, 100 to 130, and 110 to 120 millimeters, including ranges bordered and including
the foregoing values. The ratio of radius R2b to bottle diameter can vary from 1:1
to 1:200, including 1:10, 1:20, 1:30, 1:40, 1:50, 1:60, 1:70, 1:80, 1:90, 1:100, 1:120,
1:130, 1:140, 1:150, 1:160, 1:170, 1:180, 1:190, including ranges bordered and including
the foregoing values, or infinite with a radius R2b that is zero. The above ranges
are provided as examples. In some embodiments, the radii of the strap rib and/or diameter
of the bottle or other types of containers may exceed the above stated ranges and/or
ratios, such as, for example, in barrel-type containers.
[0092] In some embodiments, the radius R1b and/or radius R2b are relatively large or infinite.
Stated differently, the strap rib 40b can be straight or nearly straight from the
base end 56b to the sidewall end 42b. A straight strap rib can resist more pressure.
Providing a curvature with one or more radii to the strap rib can improve the blowing
process to help prevent poorly blown bottles, which may reduce pressure resistance.
In some embodiments, the strap rib 40b has more than one straight portion 45 as discussed
herein positioned anywhere along the strap rib 40b from the base sidewall end 42b
to the base end 56b. The straight portions 45 can be positioned to connect with curved
portions and/or other straight portions of the strap rib 40b. The straight portions
45 can be any length, including substantially an entire length of the strap rib 40b
from the sidewall end 42b to the base end 56b.
[0093] In some embodiments, the transition 41b from radius R1b to radius R2b (or more than
one transition within a strap rib having more than two radii) may be positioned anywhere
along the strap rib 40b. As shown in Figure 19, the transition 41b from radius R1b
to radius R2b occurs at height H1b. In some embodiments, the height H1b may vary from
5 to 35 millimeters, including 10 to 30, 15 to 25, and 15 to 20, including ranges
bordered and including the foregoing values, where for example, the height of the
bottle 1 may vary from 65 to 300 millimeters, including 80 to 290, 90 to 270, 100
to 260, 110 to 250, 120 to 240, 130 to 230, 140 to 220, 150 to 210, 160 to 200, 170
to 190, including ranges bordered and including the foregoing values. The ratio of
height H1b to bottle height can vary from 1:2 to 1:60, including 1:3, 1:4, 1:5, 1:6,
1:7, 1:8, 1:9, 1:10, 1:11, 1:12, 1:13, 1:14, 1:15, 1:20, 1:25, 1:30, 1:40, 1:45, 1:50,
and 1:55, including ranges bordered and including the foregoing values. The above
ranges and/or ratios are provided as examples. In some embodiments, height H1b and/or
height of the bottle or other types of containers may exceed the above stated ranges
and/or ratios, such as, for example, in barrel-type containers.
[0094] In some embodiments, the transition from radius R2b (or R1b in some embodiments)
to the straight portion 45 may be positioned anywhere along the strap rib 40b. As
shown in Figure 19, the transition from the straight portion 45 (or R2b in some embodiments)
to the sidewall end 42b occurs at height H2b. In some embodiments, the height H2b
may vary from 10 to 60 millimeters, including 15 to 55, 20 to 50, 25 to 45, and 30
to 40, including ranges bordered and including the foregoing values, where for example,
the height of the bottle 1 may vary from 65 to 300 millimeters, including 80 to 290,
90 to 270, 100 to 260, 110 to 250, 120 to 240, 130 to 230, 140 to 220, 150 to 210,
160 to 200, 170 to 190, including ranges bordered and including the foregoing values.
The ratio of height H2b to bottle height can vary from 1:2 to 1:60, including 1:3,
1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, 1:11, 1:12, 1:13, 1:14, 1:15, 1:20, 1:25, 1:30,
1:40, 1:45, 1:50, and 1:55, including ranges bordered and including the foregoing
values. In some embodiments, the straight portion 45 may extend into the sidewall
of the bottle 1 straight from radius R2b at an angle θ2b relative to the bottle sidewall
(or central axis). The angle θ2b may vary from 0 to 15 degrees, including 1, 2, 3,
4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14 degrees, including ranges bordered and including
the foregoing values. The above ranges and/or ratios are provided as examples. In
some embodiments, height H2b and/or height of the bottle or other types of containers
may exceed the above stated ranges and/or ratios, such as, for example, in barrel-type
containers.
[0095] Figure 19A illustrates a cross-section along the central axis 25 of an embodiment
of the base 24d as illustrated in Figure 5A. As shown in Figure 19A, the strap rib
40d of the base 24d begins at the base end 56d substantially parallel to a resting
surface of the base 24d and then extends along a curved path, having a first radius
R1d, with an increasingly positive slope. At a height H1d, the radius of the curved
path of the strap rib 40d changes to a second radius R2d with an increasingly positive
slope before extending into the straight portion 45. At a height H2d, the straight
portion 45 connects to the sidewall end 42d as discussed herein. The first and second
radii R1d, R2d, as well as the corresponding positive slopes, may have dimensional
values falling within any of the appropriate foregoing ranges of values. Preferably,
however, the combination of the radii R1d and R2d cooperate to give the strap rib
40d, and thus the base 24d, a smooth and gradual, spherical configuration. As discussed
herein, spherical features of the bottle 1 better accommodate internal pressure. Experimentation
has demonstrated that the spherical configuration of the base 24d depicted in Figures
5A and 19A is capable of withstanding an internal pressure at least twice the internal
pressure tolerable by the configuration shown in Figure 6A.
[0096] It will be recognized that the strap rib 40d illustrated in Figure 19A does not include
a transition curve between the first radius R1d and the second radius R2d, nor between
the second radius R2d and the straight portion 45. In other embodiments, however,
a transition curve having a radius other than R1d and R2d may be positioned between
the curved portions of the strap rib 40d having radii R1d and R2d. In still other
embodiments, a transition curve may be positioned between the curved portion of the
strap rib 40d having the second radius R2d and the straight portion 45. It is envisioned
that the transition curves may have dimensional values falling within any of the appropriate
foregoing ranges of values that further produce a spherical configuration of the strap
rib 40d, and thus the base 24d.
[0097] Figure 20 illustrates cross-sections along the central axis 25 of embodiments of
overlaid bases 24a,b as illustrated in Figures 18 and 19. As discussed herein, and
in particular, in reference to Figure 18 and 19, both strap ribs 40a,b extend from
the dome 54 and/or gate 52 from base end 56a,b at a positive angle sloping upwards
toward the sidewall of the bottle 1. As shown in Figure 20, the strap rib 40b that
extends further up the bottle sidewall may extend from the base end 56a,b at a more
positive angle upward toward the bottle sidewall to the sidewall end 42b relative
to the positive angle upward of the strap rib 40a. The strap rib 40b has a greater
radius of curvature R1b than the radius of curvature of R1a of the strap rib 40a to
extend further up the bottle sidewall as discussed herein.
[0098] Figure 21 illustrates a top perspective view of an embodiment of a bottle 3. The
bottle 3 is a substantially square bottle with four walls. The four corners of the
bottle 3 are rounded for ease of usability and ease of blowing. The bottle 3 has a
base 24e that extends to a grip portion 8. The grip portion 8 comprises a plurality
of grip portion ribs 3b (i.e., sidewall ribs). As illustrated in Figure 21, grip portion
ribs 3b (positioned in the grip portion 8) may vary in depth by separating or transitioning
from the rib a deep rib 2c to a flattened and/or shallow rib 6c to be discussed in
further detail below.
[0099] Referring to Figure 21, a label portion 10 is connected to the grip portion 8 and
comprises one or more label panel ribs 20b (i.e., sidewall ribs). The label panel
portion 10 transitions into a shoulder 18, which connects to a bell 16. The bell 16
may include scallops (including as illustrated) or other design features or it may
be smooth and generally unornamented. The bell 16 connects to a neck 14, which connects
to a finish 12. From the label portion 10, the bell 16 leads upward and radially inward,
relative to a central axis 25, to the neck 14 and finish 12. The finish 12 can be
adapted to receive a closure to seal contents in the bottle 3. The finish 12 defines
an opening 11 that leads to an interior of the bottle 3 for containing a beverage
and/or other contents. The interior can be defined as at least one of the finish 12,
the neck 14, the bell 16, the shoulder 18, the label portion 10, the grip portion
8, or the base 24e.
[0100] A substantially vertical wall (or sidewall) comprising the grip portion 8 and label
portion 10 between the base 24e and the bell 16, extending substantially along the
central axis 25 to define at least part of the interior of the bottle 3, can be considered
a sidewall of the bottle 3. In some embodiments, the sidewall may include the bell
16, shoulder 18, and/or base 24e. The perimeter of the sidewall is substantially perpendicular
to the central axis 25 of the interior. The sidewall defines at least part of the
interior of the bottle 3. The finish 12, the neck 14, the bell 16, the shoulder 18,
the label portion 10, the grip portion 8, and the base 24e can each define a respective
perimeter or circumference (substantially perpendicular to the central axis 25) corresponding
to that portion. For example, the label portion 10 has a label portion perimeter.
As another example, the grip portion 8 has a grip portion perimeter.
[0101] In the embodiment illustrated in Figure 21, each of the grip portion ribs 3b comprises
a deep rib 2c section transitioning to a middle section then to a flattened and/or
shallow rib 6c sections. As Figure 21 illustrates, each of the label panel ribs 20b
can comprise a deep rib 2d section transitioning to a middle section then to a flattened
and/or shallow rib 6d sections. A varying depth grip portion rib 3b transitions from
a deep rib 2c section to a middle rib/section then to a flattened and/or shallow rib
6b section. A varying depth label panel rib 20b transitions from a deep rib 2d to
a middle rib/section then to a flattened and/or shallow rib 6d. The one or more flattened
and/or shallow ribs 6c,d form an equivalent of recessed columns 7c at portions where
a plurality flattened and/or shallow ribs 6c,d substantially vertically line up along
the vertical or central axis 25 of the bottle 3 as illustrated in Figure 21. A plurality
of deep ribs 2c,d substantially vertically line up along the vertical or central axis
25 of the bottle 3 as illustrated in Figure 21.
[0102] In some embodiments, the flattened and/or shallow ribs 6d of the label panel ribs
20b are vertically misaligned with the flattened and/or shallow ribs 6a of the grip
portion ribs 3b such that the label portion 10 has a set of recessed columns and the
grip portion 8 has another set of recessed columns. Thus, the recessed column of the
label portion 10 can be vertically misaligned from the recessed columns of the grip
portion 8. In some embodiments, the bottle 3 can have recessed columns in just the
grip portion 8 or just the label panel portion 10.
[0103] In the illustrated embodiment with four lined-up flattened and/or shallow ribs 6a,b,
the bottle respectively has four recessed columns 7c on each flat wall of the square
bottle. The four recessed columns 7c may be equally spaced apart around the perimeter
of the bottle 3 and located on the opposite sides of the bottle 3 with respect to
each other. With four equally spaced recessed columns 7c, the recessed columns 7c
are spaced every 90 degrees around the bottle 3 perimeter. The four recessed columns
7c are positioned on the flat portions of the sidewalls of the bottle 3. Any number
of recessed columns 7c may be incorporated into a design of the bottle 3 by increasing
or decreasing the number of flattened and/or shallow ribs 6c,d that substantially
vertically line up along the vertical or central axis 25. For instance, the bottle
may have as few as 1 or up to 10 recessed columns 7c, including 2, 3, 4, 5, 6, 7,
8, or 9 recessed columns 7c, including ranges bordered and including the foregoing
values. The collections of flattened and/or shallow ribs 6c,d that form recessed columns
7c provide resistance to leaning, load crushing, and/or stretching as discussed herein.
The recessed columns 7c transfer the resulting tangential or compression forces along
the wall to the base 24e and increase bottle 3 rigidity.
[0104] The shape of the square bottle adds hoop strength to the bottle 3 by having four
corners. The deep ribs 2c,d of the grip portion ribs 3b and label panel ribs 20b can
complement the hoop strength by providing additional hoop strength. As shown in Figure
22, the deep ribs 2c,d may be positioned on the corners of the sidewall of the bottle
3. At the corners, the deep ribs 2c,d can inhibit flexing of the flat sidewall portions
of the bottle 3. The flat sidewall portions may act as membranes and flex radially
outwardly under internal pressurization of the bottle 3. The deep ribs 2c,d positioned
at the corners of the bottle 3 function as horizontal strap ribs as discussed herein
to inhibit deformation due to internal pressure. The deep ribs 2c,d positioned at
the corners can also inhibit inward radial flexing of the flat portions of the wall
from external stresses and/or forces, such as, for example, from a user gripping the
bottle. The deep ribs 2c,d can inhibit the inward flexing of the flat sidewall portions
with or without internal pressurization of the bottle 3. Thus, the deep ribs 2c,d
can help prevent rounding of the square bottle 3.
[0105] The number of ribs, including base ribs 22, grip portion ribs 3b, and/or label panel
ribs 20b may vary from 1 to 30 ribs every 10 centimeters of any rib containing portion
of the bottle, such as, but not limited to the grip portion 8 and/or label panel portion
10, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18,19, 20,
21, 22, 23, 24, 25, 26, 27, 28, or 29 ribs every 10 centimeters, including ranges
bordered and including the foregoing values. The aforementioned 10 centimeter section
that is used to measure the number of ribs need not be actually 10 centimeters in
length. Rather, 10 centimeters is used illustratively to provide a ratio for the number
of ribs.
[0106] Figure 22 illustrates a side view of an embodiment of the bottle 3. As shown in Figure
22, the grip portion ribs 3b may angulate around the perimeter of the bottle 3. The
label panel ribs 20b may be straight around the perimeter of the bottle 3. The base
24e has a strap rib 40e. The strap rib 40e has a sidewall end 42e that terminates
along the sidewall of the bottle 3 as discussed herein or near or at a transition
from the base 24e to the sidewall of the bottle 3. The base has 24e has a load rib
44e. As illustrated in Figure 22, the base 24e can have one load rib 44a for every
one strap ribs 40a. In some embodiments, the base 24e can have 2, 3, 4, and 5 load
ribs 44a between two strap ribs 40a. The load rib 44e has a sidewall end 43e that
terminates in the base 24e or near or at a transition from the base 24e to the sidewall
of the bottle 3. As illustrated in Figure 22, the sidewall end 43e of the load rib
44e may be vertically lower than the sidewall end 42e of the strap rib 40e along the
central axis 25. In some embodiments, the sidewall end 43e of the load rib 44e may
terminate along the sidewall of the bottle 3 at a same height as to the sidewall end
42e of the strap rib 40e. The base 24e has feet 45e formed between the strap ribs
40e and the load ribs 44e.
[0107] The strap rib 40e is relatively larger and deeper than the strap rib 44e as discussed
herein. As illustrated in Figure 22, the strap base rib 40e may vertically align with
the recessed columns 7c. Where a bottle 3 has four recessed columns 7c, the base 24e
can have four strap ribs 40e. The strap ribs 40e are space equally around the circumference
of the bottle 1. With four equally spaced strap ribs 40e, the strap ribs 40e are positioned
every 90 degrees around the bottle circumference. The load ribs 44e can vertically
align with the grip portion ribs 3b between the recessed columns 7c. As shown in Figure
22, the load ribs 44e may vertically align with the deep ribs 6c,d. In some embodiments,
the strap ribs 40e may be vertically misaligned with the recessed columns 7c. In some
embodiments, the strap ribs 40e may be spaced unequally around the bottle circumference.
In some embodiments, the base 24a may have more or less strap ribs 40a than the number
of recessed columns 7e.
[0108] The sidewall end 42e of the strap rib 40e vertically aligns or points to substantially
the center of the recessed columns 7c (center point of the shallow and/or flattened
ribs 2c,d). As illustrated in Figure 22, the strap rib 40e forms a recess 46e from
a side view perspective. The strap rib 40e can extend substantially from a central
portion of the base 24e (from the central axis 25) as discussed herein. The strap
rib 40e can act as a strap between the recessed columns 7c of the sidewall to the
central portion of the base 24e. As shown in Figure 22, the strap rib 40e provides
a more direct and shorter path to the center of the base 24a from the sidewall of
the bottle 3 without proceeding to the vertical level of the feet 45e. As discussed
herein, strap rib 40e thus provides relatively more pressure resistant base 24e. The
strap rib 40e provides a link for forces and stresses between the sidewall, including
the recessed column 7c, and the central portion of the base 24e.
[0109] Figure 23 illustrates a bottom perspective view of an embodiment of the base 24e.
The base 24e has a strap rib 40e and a load rib 44e as discussed herein. The base
24e has a gate 52. As shown in Figure 22, the base 24e may have a dome 54. The strap
rib 40e has a base end 56e that terminates near, at, or in the dome 54. The strap
rib 40e has a rib side wall (i.e., valley wall) 48e that connects that strap rib 40e
to portions of the base 24e and the feet 45e of the base 24a. The rib side wall 48a
smoothly and gradually transitions into the base 24e and the feet 45e. The smooth
and gradual transition provides internal pressure resistance at and near the rib side
wall 48e since more spherical features of the bottle 1 can better accommodate internal
pressure. The strap rib 40a is relatively deeper in the base 24e than the load rib
58e to provide stress transfer and pressure resistance as discussed herein.
[0110] The load rib 44e has a base end 58e that terminates at near or at the dome 54. As
shown in Figure 22, the base end 58e of the load rib 44e may terminate before the
base end 56e of the strap rib 40e. The base end 58e of the load rib 44e may terminate
at wall portion of the base 24e before reaching the dome 54. The load rib 44e is shallow
relative to the strap rib 40e. As shown in Figure 22, the load rib 44e may have a
rib side 51e feature similar as discussed herein with reference to the strap rib 40a.
The rib side 51e of the load rib 44e may be relatively smaller than the rib side 48e
of the strap rib 40e as the strap rib 40e is designed to mostly resist internal pressure
while the load rib 44e is designed to resist mostly external pressure or forces. The
transition from load rib 44e to the base 24e and the feet 45e is more abrupt or sharper
in comparison with the strap rib 44e and in particular, the rib side 48e. The sharper
transition provides external stress resistance. When the bottle 3 is top loaded during
packaging, shipping, and/or handling, sharper transitions of the load ribs 44e help
resist bending and/or leaning as discussed herein by, for example, maintaining the
integrity and shape of the base 24e.
[0111] The sharper transitions provide for faster transitions into the feet 45e of the base
24e. Faster transitions lead to more area of the base 24e being available for relatively
larger feet 45e. Larger feet 45e of a flat foot base 24e as discussed herein and as
illustrated in Figure 22 provide more resin contact area with a resting surface. More
resin contacting the resting surface provides better abrasion resistance and stability
of the base 24e.
[0112] As shown in Figure 22, the rib side wall 48e may transition into the strap rib 40e
more abruptly or sharply relative to the transition from the rib side 48e to the feet
45e. The sharper transitions at the strap rib 40e itself may provide more rigidity
to the strap rib 40e to resist or inhibit flexing due to internal pressures as discussed
herein.
[0113] Figure 24 illustrates a bottom view of an embodiment of the base 24e. As shown in
Figure 22, the strap ribs 44e may align to provide a resistance strap or band 9e (Figure
25) substantially along middle portions of the flat sidewall segments of the square
bottle 3 as discussed herein. The four strap ribs 44e complement the deep ribs 2c,d
at the sidewall corners to help prevent the square bottle 3 from rounding along the
flat portions of the sidewalls.
[0114] Figure 25 illustrates a cross-section along the central axis 25 of an embodiment
of the bottle 3 as illustrated in Figure 22. As shown in Figure 25, a flat rib or
recessed column 7e is located on an opposite side of the bottle perimeter of another
recessed column 7e. In some embodiments, the diameter Ld of the base 24 is larger
by 0.5 to 2 millimeters, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7,
1.8, or 1.9 millimeters, including ranges bordered and including the foregoing values,
than any other diameter of the bottle 3. In an embodiment with the largest diameter
of the bottle 3 being Ld, the bottle 3 has a single point of contact at just the base
24e with other substantially similar bottles in a production line and/or packaging.
Further, a larger base 24e diameter Ld may improve stability when there is any damage
to the base 24e. As shown in Figure 22, the diameter Ls at the shoulder 18 may be
equal to the diameter Ld, which provides for two points of contact, at the shoulder
18 and base 24e, with other substantially similar bottles in a production line and/or
packaging. In some embodiments, the diameter(s) in any portion of the bottle 3 varies,
where the largest diameters create points of contact in a production line and/or packaging.
The bottles may have either a single point of contact or multiple points of contact.
[0115] As shown in Figure 22, the strap ribs 40e may vertically align with the recessed
columns 7e. The strap ribs 40e and recessed column 7e in combination can form a pressure
resistance band 9e that substantially extends from a top portion of the label portion
10 or the top portion of the recessed column 7e on one side of the bottle 3 to the
base 24e and through the gate 52 along the base 24e to a top portion of the label
portion 10 or the top portion of the recessed column 7e on the other side of the bottle
3. The pressure resistance band 9e provides resistance against internal pressure substantially
for the base 24e and sidewalls of the bottle 3 such as, for example, inhibit stretching,
sidewall flexing, and/or base rollout as discussed herein. Stated differently, the
pressure resistance band 9e extends from a top portion of the label portion 10 on
one side of the bottle 3, down the sidewall on the one side of the bottle 3 and through
the gate 52, up the sidewall on the other side of the bottle 3 to a top portion of
the label portion 10 on the other side of the bottle 3 to provide pressure resistance
as discussed here and substantially continuously through a longitudinal perimeter
of the bottle 3 (along the central axis 25 at the sidewalls and through the central
axis at the base 24e).
[0116] Figure 26 is a table and graph showing an increase in top load resistance in lbf.
with increased pressure in a bottle 1,3. The maximum top load increased by 13% for
certain bottles, and the minimum top load increases by 11% for certain bottles, with
an average increase of 6%. The y-axis of the graph shows top load pressure applied
to the bottle in lbf. The x-axis of the graph shows the displacement performance of
the bottle under the corresponding top load pressure. Curve 60 shows top load performance
of the bottle under typical pressure or pressurization inside the bottle. Curve 62
shows top load performance of the bottle under typical flat pressure or no pressurization
inside the bottle. The graph illustrates a stiffer initial performance of the bottles
(up to about 50, 40, and 30 lbf. (222, 178, 133 newtons, respectively)) and a delayed
reversible failure of some bottle embodiments (at about 50, 40, and 30 lbf. (222,
178, 133 newtons, respectively)) disclosed herein. Performance improvements can be
greater with some embodiments. At the forces and/or pressures illustrated in the graph,
the bottles show minimal or no permanent deformation. The bottles rebound to a desired
shape after a deforming force is released. This is beneficial for rough handling during
packaging, shipping, and/or handling, such as, for example, in the warehouse or shipping
lane.
[0117] Referring to Figure 27, the bell 16 may have various bell angles 26 as measured from
the vertical wall of the finish 12 to the downward sloping wall of the bell 16. The
bell angle 26 may be obtuse, varying from 120 to 175 degrees, including 122, 125,
127, 130, 132, 135, 137, 140, 142, 145, 147, 150, 152, 155, 157, 160, 162, 165, 167,
170, or 172 degrees, including ranges bordered and including the foregoing values.
The bell angle 26 represented by 02 is larger than the bell angle 26 represented by
01. The wall of bell 16 with 02 bell angle 26 is steeper than the wall of bell 16
with 01 bell angle 26. A steeper wall of bell 16 can increase the top load capacity
of the bottle 1 while maintaining the same or even decreasing bell 16 wall thickness.
A steeper bell angle 26 aids in resin of a preform to touch the preform mold more
quickly (relative to a less steep angle) during the blow molding process. When the
resin touches the preform mold more quickly, more of resin is quenched earlier to
remain in the sidewalls of the bottle, leading to thicker sidewalls. Thicker sidewalls
can help increase top load and pressure resistance performance as discussed herein.
[0118] Referring to Figure 28, an embodiment of the bottle 1 may use a preform 38 with a
thin wall finish 12 and a thin wall neck 14 to form a lightweight bottle. A thin wall
neck 14 improves the ability to blow efficient, lightweight bottles. A thin wall neck
14 is a feature that aids in protecting critical dimensions of the bottle and stabilizing
the production blowing process. A thin wall neck 14 can also utilize less resin while
achieving the desired mechanical performance resulting in a reduction in the use of
petroleum products by the industry. A thin wall neck 14 of preform 38 can aid in forming
bottles 1 with larger bell angles 26 and/or steeper bell 16 walls as discussed above.
As also discussed above, steeper, but relatively thinner, bell 16 walls can support
greater top load forces, which can be transferred to the base 24 via the recessed
columns. Thus, embodiments disclosed herein may incorporate thicker base 24 designs
and/or thicker sidewall designs to withstand greater top load forces even when damaged,
while using the same or less amount of resin. Achieving a thicker base 24 and/or thicker
sidewalls is aided by a thin wall neck 14 and thin bell 16 walls.
[0119] It is contemplated that various combinations or subcombinations of the specific features
and aspects of the embodiments disclosed above may be made and still fall within one
or more of the inventions. Further, the disclosure herein of any particular feature,
aspect, method, property, characteristic, quality, attribute, element, or the like
in connection with an embodiment can be used in all other embodiments set forth herein.
Accordingly, it should be understood that various features and aspects of the disclosed
embodiments can be combined with or substituted for one another in order to form varying
modes of the disclosed inventions. Thus, it is intended that the scope of the present
inventions herein disclosed should not be limited by the particular disclosed embodiments
described above. Moreover, while the invention is susceptible to various modifications,
and alternative forms, specific examples thereof have been shown in the drawings and
are herein described in detail. It should be understood, however, that the invention
is not to be limited to the particular forms or methods disclosed, but to the contrary,
the invention is to cover all modifications, equivalents, and alternatives falling
within the spirit and scope of the various embodiments described and the appended
claims. Any methods disclosed herein need not be performed in the order recited. The
methods disclosed herein include certain actions taken by a practitioner; however,
they can also include any third-party instruction of those actions, either expressly
or by implication. For example, actions such as "passing a suspension line through
the base of the tongue" include "instructing the passing of a suspension line through
the base of the tongue." It is to be understood that such depicted architectures are
merely examples, and that in fact many other architectures can be implemented which
achieve the same functionality. In a conceptual sense, any arrangement of components
to achieve the same functionality is effectively "associated" such that the desired
functionality is achieved. Hence, any two components herein combined to achieve a
particular functionality can be seen as "associated with" each other such that the
desired functionality is achieved, irrespective of architectures or intermedial components.
The ranges disclosed herein also encompass any and all overlap, sub-ranges, and combinations
thereof Language such as "up to," "at least," "greater than," "less than," "between,"
and the like includes the number recited. Numbers preceded by a term such as "approximately",
"about", and "substantially" as used herein include the recited numbers, and also
represent an amount close to the stated amount that still performs a desired function
or achieves a desired result. For example, the terms "approximately", "about", and
"substantially" may refer to an amount that is within less than 10% of, within less
than 5% of, within less than 1% of, within less than 0.1% of, and within less than
0.01% of the stated amount.
[0120] With respect to the use of substantially any plural and/or singular terms herein,
those having skill in the art can translate from the plural to the singular and/or
from the singular to the plural as is appropriate to the context and/or application.
The various singular/plural permutations may be expressly set forth herein for sake
of clarity.
[0121] It will be understood by those within the art that, in general, terms used herein
are generally intended as "open" terms (e.g., the term "including" should be interpreted
as "including but not limited to," the term "having" should be interpreted as "having
at least," the term "includes" should be interpreted as "includes but is not limited
to," etc.). It will be further understood by those within the art that if a specific
number of an introduced embodiment recitation is intended, such an intent will be
explicitly recited in the embodiment, and in the absence of such recitation no such
intent is present. For example, as an aid to understanding, the following disclosure
may contain usage of the introductory phrases "at least one" and "one or more" to
introduce embodiment recitations. However, the use of such phrases should not be construed
to imply that the introduction of an embodiment recitation by the indefinite articles
"a" or "an" limits any particular embodiment containing such introduced embodiment
recitation to embodiments containing only one such recitation, even when the same
embodiment includes the introductory phrases "one or more" or "at least one" and indefinite
articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted
to mean "at least one" or "one or more"); the same holds true for the use of definite
articles used to introduce embodiment recitations. In addition, even if a specific
number of an introduced embodiment recitation is explicitly recited, those skilled
in the art will recognize that such recitation should typically be interpreted to
mean at least the recited number (e.g., the bare recitation of "two recitations,"
without other modifiers, typically means at least two recitations, or two or more
recitations). Furthermore, in those instances where a convention analogous to "at
least one of A, B, and C" or "one of the A, B, or C," etc. is used, in general such
a construction is intended in the sense one having skill in the art would understand
the convention (e.g., "a system having at least one of A, B, and C (or one of the
A, B, or C)" would include but not be limited to systems that have A alone, B alone,
C alone, A and B together, A and C together, B and C together, and/or A, B, and C
together, etc.). In those instances where a convention analogous to "at least one
of A, B, or C, etc." is used, in general such a construction is intended in the sense
one having skill in the art would understand the convention (e.g., "a system having
at least one of A, B, or C" would include but not be limited to systems that have
A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or
A, B, and C together, etc.). It will be further understood by those within the art
that virtually any disjunctive word and/or phrase presenting two or more alternative
terms, whether in the description, embodiments, or drawings, should be understood
to contemplate the possibilities of including one of the terms, either of the terms,
or both terms. For example, the phrase "A or B" will be understood to include the
possibilities of "A" or "B" or "A and B."
[0122] While various aspects and embodiments have been disclosed herein, other aspects and
embodiments will be apparent to those skilled in the art. The various aspects and
embodiments disclosed herein are for purposes of illustration and are not intended
to be limiting.
