FIELD OF THE INVENTION
[0001] The present invention relates to the field of packaging oral care implements, and
specifically to a package of oral care implements having a moisture sensitive pre-applied
oral care material.
BACKGROUND OF THE INVENTION
[0002] The advantages of good dental hygiene are well known. Often, however, oral care implements
cannot be used due to a lack of a water source, such as when a user is driving in
a vehicle or on-the-go. Oral care implements that can be used without a water source
have recently been developed. For example, oral care implements have been developed
that provide an oral care material within the oral care implement itself, such as
through an integrated channel, for distribution through the oral care implement to
the bristles. Disposable waterless oral care implements that utilize a pre-applied
moisture sensitive capsule have also been introduced into the market.
[0003] Oral care implements, such as those described above, must be maintained in a sealed
environment prior to use in order to prevent moisture from prematurely degrading and/or
releasing the oral care material. As such, these oral care implements must be carefully
packaged. Furthermore, users of disposable oral care implements need a place to dispose
the oral care implements after use. Disposable oral care implements of the type discussed
above are currently packaged in plastic clamshell packages that are individually foil-sealed
for protection. If a user uses a disposable oral care implement in a vehicle or another
"on-the-go" location, the user must resort to either leaving the used disposable oral
care implement loose within the vehicle or holding onto it until a proper waste basket
can be located.
[0004] Hence, there is a need for a package that can contain oral care implements in a moisture-free
environment prior to use. Furthermore, there is a need for a package that can contain
a plurality of oral care implements such that one of the oral care implements can
be removed from the package for use while the remainder of the oral care implements
remain in a moisture protected environment.
[0005] A need also exists for a package of oral care implements that is designed to resemble
a cup that can be positioned within a vehicle cup holder. Furthermore, a need exists
for a package of oral care implements that provide a disposal cavity after use.

DETAILED DESCRIPTION OF THE INVENTION
[0013] The following description of the preferred embodiment(s) is merely exemplary in nature
and is in no way intended to limit the invention, its application, or uses.
[0014] The description of illustrative embodiments according to principles of the present
invention is intended to be read in connection with the accompanying drawings, which
are to be considered part of the entire written description. In the description of
the exemplary embodiments of the invention disclosed herein, any reference to direction
or orientation is merely intended for convenience of description and is not intended
in any way to limit the scope of the present invention. Relative terms such as "lower,"
"upper," "horizontal," "vertical," "above," "below," "up," "down," "left," "right,"
"top," "bottom," "front" and "rear" as well as derivatives thereof (e.g., "horizontally,"
"downwardly," "upwardly," etc.) should be construed to refer to the orientation as
then described or as shown in the drawing under discussion. These relative terms are
for convenience of description only and do not require that the apparatus be constructed
or operated in a particular orientation unless explicitly indicated as such. Terms
such as "attached," "affixed," "connected," "coupled," "interconnected," "secured"
and similar refer to a relationship wherein structures are secured or attached to
one another either directly or indirectly through intervening structures, as well
as both movable or rigid attachments or relationships, unless expressly described
otherwise. Moreover, the features and benefits of the invention are described by reference
to the exemplary embodiments illustrated herein. Accordingly, the invention expressly
should not be limited to such exemplary embodiments, even if indicated as being preferred.
The discussion herein describes and illustrates some possible non-limiting combinations
of features that may exist alone or in other combinations of features. The scope of
the invention is defined by the claims appended hereto.
[0015] Referring to FIGS. 1 and 2, one embodiment of an oral care implement
100 that is particularly suited for use with the present invention is exemplified. As
will become apparent from the discussion below, it is preferred that the oral care
implement
100 be packaged in a manner that protects the oral care implement
100 against moisture and/or humidity. The oral care implement
100 extends from a proximal end
101 to a distal end
102 and includes a head
112 and a handle
114. The oral care implement
100 includes a tail portion
103 located at the proximal end
101, and a head portion
104 located at the distal end
102. The head
112 may either be a refill head that is removably connected to the handle
114 or a structure that is permanently connected to the handle
114. The majority of the handle
114 and a portion of the head
112 may be molded from a variety of rigid materials, including without limitation plastics,
resins and the like. One suitable rigid material is polypropylene. However, other
rigid materials may be used as would be known to persons skilled in the art.
[0016] In the illustrated embodiment, the tail portion
103 of the oral care implement
100, which is opposite the head portion
104 to which the head
112 is located, comprises an oral care accessory, which in the exemplified embodiment
is a toothpick
116. The toothpick
116 is preferably formed of a resilient and soft thermoplastic elastomer. As with the
head
112, the toothpick
116 may be a refill toothpick that is removably connected to the handle
114 or may be permanently connected to the handle
114. The toothpick
116 provides a mechanism for spot cleaning between teeth. Forming the toothpick
116 of a soft thermoplastic elastomer provides a more comfortable interproximal cleaning
between the teeth. The toothpick
116 could, however, be made of a stiff, rigid material similar to the main portion of
the handle
114, or could simply be a rubber or elastomeric pick adhered or otherwise mounted to the
end of the handle
114. Alternatively, a different accessory, such as a strip of dental floss or a tongue
cleaning element, may be attached to the tail portion
103 of the oral care implement
100. Moreover, in certain embodiments of the invention, the oral care implement
100 may not include an accessory or may include multiple accessories.
[0017] The head
112 comprises a cleaning element block
122. The cleaning element block
122 comprises a plurality of bristles extending from the head
114. The bristles of the cleaning element block
122 may be of any desired shape. For example, the bristles could be of cylindrical shape
having a uniform diameter throughout their length. Alternatively, the bristles could
taper from the root where they extend from the head
122 to their outer cleaning ends. It is understood that the cleaning element block
122 may include other cleaning elements.
[0018] Furthermore, the dimensions of the various components of the oral care implement
100 are preferably small. Thus, for example, each bristle of the cleaning element block
122 may extend outwardly from the outer surface of the head
112 a distance no greater than 10mm and preferably no greater than 8mm and most preferably
no greater than 6mm. Where tapered cleaning elements are used, the root diameter should
be no greater than 1.5mm, more preferably between 0.5mm and 1mm, and most preferably
no greater than 0.3mm. The diameter could then decrease in size with distance from
the head
112. Preferably, the length of the entire oral care implement
100 is no greater than 12.7cm (5 inches), more preferably no greater than 10.16cm (4
inches) and most preferably in the range of 5.08cm to 10.16cm (2 to 4 inches).
[0019] A central portion of the head
112, which is surrounded by the cleaning element block
122, comprises a depression or cavity for retaining a rupturable gel capsule or bead
132. The gel capsule
132 is filled with an oral care material, such as a fluidic solution, for cleaning or
otherwise providing health benefits to a user's oral cavity. The oral care material
may be toothpowder, toothpaste, tooth cleaning gel, mouthwash or a similar dentifrice
or oral hygiene product, or a combination of the same. The gel capsule
132 is moisture-sensitive and should be protected against high humidity environments
in order to prevent premature rupture. In other words, the gel capsule
132, or at least a portion thereof, is susceptible to degradation when subjected to a
high humidity atmosphere as it has been discovered that moisture in the air in a high
humidity environment can degrade the integrity of the gel capsule
132. Therefore, it is desirable to package the oral care implement
100 in a manner that protects the gel capsule
132 from humidity and liquid moisture prior to use.
[0020] The gel capsule
132 holds and applies an oral care material onto the tooth cleaning elements
122 of the oral care implement head
112, and ultimately to a user's teeth and oral care surfaces. As mentioned above, the
oral care material may be toothpaste, a gel, a mouthwash, or a similar dentifrice
or oral hygiene product, or a combination of the same. Preferably, the gel capsule
132 is a liquid-filled gel capsule having a shell comprising frangible, thin walls that
easily rupture or burst when rubbed against the teeth. In a preferred embodiment,
the gel capsule
132 degrades when subjected to moisture and, thus, dissolves when mixed with the saliva
of a user. As the saliva of a user degrades and dissolves the walls of the gel capsule
132, the oral care solution held therein is excreted. While the degradation of the gel
capsule
132 is a desired characteristic for effectuating end use of the oral care implement
100 by the consumer, the moisture-driven degradation of the gel capsule
132 presents issues with respect to properly preserving the integrity of the gel capsule
132 during product manufacturing, packaging, shipping and display in retail stores.
[0021] The gel capsule
132, or at least a portion thereof, is susceptible to degradation when subjected not only
to direct contact with liquid water but also to prolonged exposure to atmospheres
having a high humidity level. It has been discovered that a high humidity environment
can degrade the integrity of the gel capsule
132 and prematurely expel the oral care material or cause the oral care material to dry
up. Of course, the exact humidity levels and exposure times that will result in the
degradation of the gel capsule
132 will be determined on a case-by-case basis, considering such factors as the type
of gel capsule
132 being used, the type of oral care material, and the thermal cycling to which the
oral care implement
100 is subjected. In view of the foregoing, it is desirable that the gel capsule
132 (and potentially the entire oral care implement
100) be placed in a package that forms a sealed cavity in which at least the gel capsule
132 of the oral care implement
100 is disposed, thereby protecting the gel capsule
132 from external moisture which can be in the form a high humidity atmosphere or liquid
water. In certain embodiments, the sealed cavity may be hermetically sealed.
[0022] In one preferred embodiment of the present invention, the entire structure of the
oral care implement
100, including the head
112, the handle
114, and the toothpick
116, is molded as one integral structure, using a conventional two-component injection
molding operation typically used in the manufacture of oral care implements. This
enables the oral care implement
100 to be economically and quickly manufactured. Although the oral care implement
100 may be constructed in a wide variety of sizes, shapes and relative dimensions, it
is preferred that the oral care implement
100 have a small profile so that it is easily portable and can be discreetly used. In
one embodiment, it is preferred that the head
112 be small enough to cover a single tooth at a time and that the handle
114 be substantially thinner than conventional, everyday oral care implement handles.
[0023] Since the oral care implement
100 is intended to be both small and lightweight, it is preferred that the oral care
implement
100 weigh no more than 3 grams in certain embodiments. The small size allows the oral
care implement
100 to be held completely within the palm of an adult user's hand. The head
112 is preferably sized to correspond to the size of an individual tooth or an individual
tooth and the interproximal areas. While the head
112 could be made in any suitable shape, it is preferably of circular or oval shape and
has a maximum lateral dimension or diameter of no greater than 13mm, preferably no
greater than 12mm and most preferably no greater than 11mm. Of course, the oral care
implement
100 is not limited to any specific dimensions or shapes.
[0024] It is to be understood that the present invention is not limited to the above-described
oral care implement
100. While the inventive package will be described in combination with a plurality of
the oral care implements
100, it is to be understood that other oral care implements can be packaged as discussed
below. In certain embodiments of the invention, the package is in no way limited to
the structure of the oral care implement
100 unless specifically stated in the claims. In the exemplary embodiment, the oral care
implement
100 disposed within the package is one which is disposable, has a pre-applied oral care
material, and must be protected against moisture. However, in certain other embodiments,
a conventional toothbrush or any other type of oral care implement may be disposed
within the package, irrespective of whether it must be protected against moisture
and/or contains a pre-applied oral care material. As used herein, pre-applied means
that the oral care material is associated with the oral care implement as-packaged
for sale.
[0025] Referring to FIGS. 3-5 concurrently, a package
300 containing a plurality of the oral care implements
100 according to a first comparative example is illustrated. The package
300 is designed to keep moisture out of the subcavities containing the oral care implements
100 so that the pre-applied oral care material, which is in the form of the gel capsule
132, is protected from degradation due to humidity and/or moisture. Of course, in arrangements
where the oral care implements contained within the package
300 do not need to be protected against moisture degradation, the package
300 need not be hermetically sealed.
[0026] The package
300 generally comprises a tubular body
301 having an annular wall
302 that forms a cavity
305. In the first comparative example, the annular wall
302 has a circular transverse cross-sectional profile. The circular transverse cross-sectional
profile shape is beneficial when the package
300 is designed for positioning in a cup holder of a vehicle. In such an embodiment,
the package
300 preferably has a diameter
D1 that is between 60-80mm. In certain other arrangements, the package
300 may take on a tapered shape (not shown) such that the diameter
D1 of the package
300 is larger at a top end
303 of the package
300 than at a bottom end
304 of the package
300 or vice versa. Of course, the invention is not so limited and in certain other embodiments,
the transverse cross-sectional profile of the annular wall
302 may be almost any shape, including without limitation rectangular, trapezoidal, oval,
triangular or otherwise polygonal.
[0027] The package
300 comprises a plurality of inner walls
310 positioned within the cavity 305. The inner walls
310 divide the cavity
305 into a plurality of subcavities
306. Each of the subcavities
306 comprises a top end
308 and a bottom end
309. In the first comparative example, the inner walls
310 form a rectilinear gridwork of walls. Of course, the invention is not so limited
and the inner walls
310 may take on any other form so long as the inner walls
310 divide the cavity
305 into a plurality of subcavities
306.
[0028] Referring solely to FIG. 4, the rectilinear gridwork is illustrated in greater detail.
The rectilinear gridwork is a preferable arrangement of the inner walls
310 because it maximizes the amount of cavity space that is being used when the annular
wall
302 has a circular transverse cross-sectional profile. In the exemplary arrangement in
which a circular transverse cross-sectional profile of the annular wall
302 is utilized, some of the subcavities
306 are empty because they are not large enough to contain one of the oral care implements
100 therein. However, as discussed above, the circular transverse cross-sectional profile
is preferable when the package
300 is being stored in a vehicle cup holder. In arrangements where the transverse cross-sectional
profile of the annular wall
302 is rectangular, the inner walls 310 may be in the form of a Cartesian gridwork in
order to maximize the used cavity space. Each of the subcavities
306 may be the same size or different sizes. For example, in arrangements where different
types of oral care implements are stored in the package
300, each of the subcavities
306 may be different sizes to store the different types of oral care implements. Stated
simply, the number and size of the subcavities
306 are in no way limiting of the present invention in all embodiments.
[0029] Referring again to FIGS. 3-5 concurrently, the bottom end
304 of the package
300 is enclosed by a floor
307. The floor
307 is coupled to the annular wall
302 and each of the inner walls
310 so as to seal the bottom end
309 of each of the plurality of subcavities
306. As will be described in more detail below, in certain arrangements, the floor
307 is a separate component from the annular wall
302 and the inner walls
310 and is attached to the annular wall
302 and the inner walls
310 at a later stage in the manufacturing process. Of course, the invention is not so
limited and in certain other embodiments the floor
307 may be formed integrally with the other components of the package
300.
[0030] In the first comparative example, exactly one oral care implement
100 is disposed within each of the subcavities
306. Thus, in such an arrangement the transverse cross-sectional dimensions of each of
the subcavities are approximately between 6-20mm, and more preferably between 10-15mm.
Of course, the size of the subcavities
306 may be larger or smaller than the ranges discussed herein in order to accommodate
larger or smaller oral care implements, or to accommodate more than a single one of
the oral care implements
100 therein.
[0031] The oral care implements
100 are arranged in the subcavities
306 so that the tail portions
103 of the oral care implements
100 are adjacent the top ends
308 of the subcavities
306 and the head portions
104 of the oral care implements
100 are adjacent the bottom ends
309 of the subcavities
306. Positioning the oral care implements
100 in the subcavities
306 in this manner provides for easier gripping of the oral care implements
100 by the user for removal from the subcavities
306 as will be described in more detail below. Of course, the invention is not to be
limited by the particular arrangement of the oral care implements
100 within the subcavities
306, unless specifically recited in the claims
[0032] The package
300 comprises a film
320 that seals the top ends
308 of each of the plurality of subcavities
306. More specifically, the film
320 is attached to a top edge
312 of the annular wall
302 and a top edge
311 of the inner walls
310. Thus, a combination of the annular wall
302, the inner walls
310, the floor
307 and the film
320 creates an environment within each of the plurality of subcavities
306 such that each subcavity
306 is sealed with respect to the other subcavities
306 and to an environment external to the package
300, such as the ambient atmosphere. Creating an environment within each of the plurality
of subcavities
306 that is sealed from each of the other subcavities
306 assists with maintaining a moisture-free environment within each of the subcavities
306 prior to use of the particular oral care implement 100 within that subcavity
306. In some arrangements, subcavity
306 is hermetically sealed.
[0033] The film
320 is preferably a thin sheet of material that encloses the entire top end
303 of the package
300, thereby also enclosing the top ends
308 of each of the subcavities
306. The film
320 can be, for example without limitation, a laminate, a foil, a wax paper or a plastic
sheet. The film
320 is preferably flexible, but may be rigid in certain arrangements. Furthermore, any
other materials that can seal the top ends
308 of each of the subcavities
306 as would be known to persons skilled in the art may also be used for the film
320. The film
320 can be attached to the top edges (or surfaces) of the tubular body
301 by any number of means, including adhesion, thermal bonding, static, friction, or
combinations thereof.
[0034] In one arrangement, the film
320 is a substantially transparent material. By creating the film
320 out of a transparent material, a user can easily see through the film
320 into each of the subcavities
306 to determine whether an oral care implement
100 is disposed therein. By allowing a user to see though the film
320 may also allow the user to choose the oral care implement
100 he or she wishes to retrieve in arrangements where different types of oral care implements
are stored in the package
300. However, the invention is not so limited and the film
320 may be translucent or opaque. Furthermore, the film
320 may be colored in any desired fashion including a solid color or a patterned coloring
arrangement. In some arrangements, a patterned coloring arrangement consisting of
different color film segments
321 may denote to the user the different type of oral care implements that are stored
in the package
300.
[0035] The film
320 is divided into a plurality of film segments
321 that are separable from each other. The film segments
321 are not limited to an arrangement comprising a single film that is subsequently divided
into segments but also includes arrangements where completely separate and distinct
segments of film
320 are separately applied. In one arrangement, the film segments
321 may be a single film covering the entire top end
303 of the package
300 that is subsequently separated into the film segments
321 by pre-weakening portions
322 on the film
320. Regardless of how the film segments
321 are created, the film segments
321 collectively form the film
320. Furthermore, it should be understood that the top end
308 of each one of the subcavities
306 is sealed by a corresponding one of the film segments
321.
[0036] The film
320 is coupled to the package
300 in a manner so that access can be obtained into a single one of the subcavities
306 while the other subcavities
306 remain sealed from each other and the external environment. In order to gain access
into a single one of the subcavities
306, the film segment
321 that is sealing that particular subcavity
306 must be removed, penetrated or otherwise opened so that the subcavity
306 is no longer covered or sealed by the film segment
321. In some arrangements, the film segment
321 hermetically seals the subcavity
306. In the first comparative example, the pre-weakened portions
322 that separate the film
320 into the film segments
321 are portions of the film
320 between adjacent film segments
321. Specifically, the pre-weakened portions
322 of the film
320 are the portions of the film
320 that overlie and are attached to the top edges
311 of the inner walls
310 between adjacent film segments
321. In the first comparative example, the film
320 also has a pre-weakened portion
322 overlying the top edge
312 of the annular wall
310. However, in certain other arrangements, the portion of the film
320 that overlies the top edge
312 of the annular wall
310 is not pre-weakened. The pre-weakened portions
322 can be perforated seams, heat-weakened seams or cut seams located between adjacent
film segments
321.
[0037] As discussed above, in order to gain access into one of the subcavities
306 for removal of the oral care implement
100 disposed therein, the film segment
321 that is sealing that particular subcavity
306 must be manipulated. Manipulating the film segment
321 includes removing or penetrating the film segment
321 or otherwise creating an opening in the film
320 in the area of the film segment
321 that is covering a particular subcavity
306 so that the subcavity
306 is no longer covered by the film segment
321. Due to the pre-weakened portions
322, the film segments
321 are easily penetrated or removed. Specifically, when a force
F is applied to a selected film segment
323 of the plurality of film segments
321 that is enclosing a selected subcavity
316 of the plurality of subcavities
306, the film
320 breaks along the pre-weakened portions
322 surrounding the selected film segment
323. As such, the selected film segment
323 becomes separated from the remainder of the film
320 and a passageway is formed from the external environment into the selected subcavity
316 that was sealed by the selected film segment
323. It should be understood that the force
F is preferably the force of a user's finger pressing down on the selected film segment
323. However, the invention is not so limited and the force
F can be obtained by an object being pressed against the selected film segment
323 or in any other manner as would be understood by persons skilled in the art.
[0038] In certain other arrangements not illustrated, each of the film segments
321 may have a corresponding tab that is able to be gripped by a user. In such an arrangement,
when the user desires to gain access into the selected subcavity
316, the user grips the tab and pulls the selected film segment
323 away from the subcavity in order to provide a passageway into the selected subcavity
316. Regardless of how the selected film segment
323 is manipulated to create a passageway into the selected subcavity
316, once the selected subcavity
316 is open, the oral care implement
100 disposed in the selected subcavity
316 will be exposed. As such, the user will be able to grip the oral care implement
100 and remove it from the selected subcavity
316 for use. As discussed above, it is preferable that the tail portion
103 of the oral care implement
100 be positioned adjacent the top ends
308 of the subcavities
306. This is because the tail portion
103 of the oral care implements
100 are smaller than the head portions
104, which will make it easier for a user to grip the oral care implement
100 and remove it from the subcavity
306.
[0039] After the user grips the oral care implement
100 and removes it from its corresponding subcavity
306, the user can use the oral care implement to cleanse his or her oral cavity. The gel
capsule
132 will rupture upon use either by dissolving in the user's saliva or being punctured
by the user's teeth, and the user's teeth and other oral surfaces will benefit from
the contents of the gel capsule
132. In certain embodiments as discussed above, the oral care implement
100 is intended for one-time use and is therefore disposable. Thus, after use, the user
can discard the oral care implement
100 by replacing the oral care implement
100 back into the selected subcavity
316 from which it came. As such, the package
300 can be used as a container for storing the oral care implements
100 prior to use and as a waste basket for discarding of the oral care implements
100 after use. If the package
300 is sized and configured to fit within the cup holder of a vehicle, this will prevent
users from leaving the used oral care implements
100 loose within the vehicle.
[0040] In certain embodiments, as will be described in more detail below with reference
to FIGS. 7 and 10, the film
320 is also re-sealable. A user may find it unattractive to have the used oral care implements
100 merely positioned uncovered in the subcavities
306. Thus, by re-sealing the film
320, the used oral care implements
100 can be blocked from view.
[0041] In certain embodiments, the package
300 also comprises a lid (not shown). One embodiment of a lid will be discussed in detail
below with reference to FIG. 9. However, the lid may take on any known lid embodiments.
Specifically, the lid may be a snap-fit, press-fit, interference fit or other type
of lid that covers the top ends
308 of the subcavities
306 above the film
320. More specifically, the lid will be coupled to the tubular body
301 so that the film
320 is located between a bottom surface of the lid and the tubular body
301. The lid will prevent the film
320 from being prematurely punctured, opened or removed during manufacturing, packaging,
shipping and display at a retail store for sale to an end user. The lid is preferably
made of the same materials as the other components of the package
300 as will be discussed below. However, the lid may be formed of any materials so long
as the lid protects the film
320 from premature puncture. Any of the embodiments discussed herein, whether illustrated
with a lid or not, may be manufactured, shipped, displayed and sold with a lid.
[0042] Referring solely to FIG. 5, an arrangement of the package
300 that comprises a desiccant
380 will be described. In certain arrangements, the desiccant
380 is positioned within the package
300 in order to remove any moisture that may seep into the subcavities
306 of the package
300. Thus, the package
300 further comprises a transverse plate
360 positioned within each of the subcavities
306 that separates each of the subcavities
306 into an upper chamber
362 and a lower chamber
363. Conceptually, the package
300 can be considered to include a single transverse plate
360 extending transversely across the entirety of the cavity
305 generally parallel to the floor
307. The upper chamber
362 extends between the film
320 and a top surface
364 of the transverse plate
360. Similarly, the lower chamber
363 extends between a bottom surface
365 of the transverse plate
360 and the top surface
312 of the floor
307. In the exemplified embodiment, the transverse plate
360 is integrally formed as a unitary part with the annular wall
302 and the inner walls
310. The manufacturing process involved in creating the package
300 with the desiccant
380 will be described in greater detail below.
[0043] In the exemplified arrangement, the transverse plate
360 comprises a plurality of openings
361, each of which provides a passageway between the upper and lower chambers
362, 363 of the subcavities
306. In other words, for each subcavity
306, air within the upper chamber
362 is able to flow downward into the lower chamber
363 through the openings
361 and vice versa. As will be better understood from the discussion below, it is preferable
that there is at least one opening
361 in a portion of the transverse plate
360 that is disposed within each of the plurality of subcavities
306. This will enable air to circulate between the upper and lower chambers
362, 363 in each of the subcavities
306. In the exemplified embodiment, there are three openings
361 in the transverse plate
360 in each of the subcavities
306. However, the invention is not so limited and there can be more or less openings
361 in the transverse plate
360 as desired. Furthermore, it should be understood that in certain other embodiments,
the transverse plate
360 can be omitted altogether.
[0044] In the exemplified arrangement, the desiccant
380 is disposed in the lower chamber
363. The desiccant
380 may be any material that is known to induce or sustain a state of dryness in its
local vicinity in a moderately well-sealed container. The desiccant
380 may be, for example without limitation, silica gel, calcium sulfate, calcium chloride,
montmorillonite clay, molecular sieves, rice, salt or the like. Other desiccants that
are now known or later discovered that can sustain a state of dryness within a sealed
container while not transmitting any toxins to the oral care implements
100 disposed within the subcavities
306 may be used.
[0045] The oral care implements
100 are disposed in the upper chamber
362. Thus, the entire package
300 only needs to be large enough in height to contain the oral care implements
100, which may be as small as 5.08cm to 10.16cm (2 to 4 inches), and the desiccant
380, which may simply be a layer of salt disposed in the lower chamber
363.
[0046] Due to the openings
361 in the transverse plate
360, the desiccant
380 will absorb any moisture within either of the upper and lower chambers
362, 363 because the air within the subcavities
306 will freely flow between the upper and lower chambers
362, 363 through the openings
361 in the transverse plate
360. Thus, the desiccant
380 will remove excess humidity that would otherwise degrade or potentially destroy the
oral care implements
100 within the upper chamber
362.
[0047] It is preferred that the oral care implements
100 be placed in the package
300 at a relative humidity level that is less than 70% at room temperature, preferably
less than 60% at room temperature, more preferably less than 50% at room temperature,
and most preferably less than 40% at room temperature in order to avoid degradation
of the gel capsules
132. However, in certain embodiments, even if an atmosphere having a higher humidity is
initially trapped within the subcavities
306, the desiccant
380 in the lower chamber
363 will be able to absorb the excess moisture without degrading the gel capsule
132 of the oral care implement
100. However, the subcavities
306 are air-tight as discussed above in order to prevent further exposure of the gel
capsule
132 of the oral care implement
100 to moisture, thereby keeping the gel capsule
132 intact.
[0048] The annular wall
302, the inner walls
310, the transverse plate
360 and the floor
307 can be formed of any type of material as would be known to persons skilled in the
art. Specifically, the material may be a metal or metal alloy, or a thermoplastic
such as for example polypropylene, polyethylene, polystyrene, or polyvinyl chloride.
Of course, the invention is not so limited and other materials as would be known to
persons skilled in the art can be used.
[0049] The package
300 can be formed in a multi-step process. Specifically, in one arrangement, the annular
wall
302, the inner walls
310 and the transverse plate
160 are formed in a single step injection molding process. After the annular walls
302, the inner walls
310 and the transverse plate
360 are formed, the lower chamber
363 is filled with the desiccant
380. Then, after the desiccant
380 is properly positioned, the floor
307, which is in the form of a plate, is connected to the annular wall
302 and the inner walls
310 so as to enclose the bottom ends of the annular walls
302 and the inner walls
310.
[0050] The floor
307 can be created in a second injection molding step and then attached or coupled to
the annular wall
302 and the inner walls
310 at a later stage of the manufacturing process. The coupling of the floor
307 to the annular wall
302 and the inner walls
310 can be achieved by any suitable technique known in the art, including without limitation
thermal welding, a tight-fit assembly, a coupling sleeve, adhesion, fasteners or the
like. It should be understood that the various components of the package
300 may be formed by methods other than molding, such as, for example, milling, machine,
or other suitable process.
[0051] It should be understood that the desiccant
380 may be omitted altogether in certain arrangements. In such arrangements, the floor
307 may be formed integrally with the annular wall
302 and the inner walls
310. The arrangements discussed below are not specifically discussed or illustrated as
having a desiccant. However, the structure of the package embodiments discussed below
may be manufactured as discussed above so that the desiccant
380 can be included in the package for moisture absorption. Furthermore, as discussed
above, the package
300 is preferably sized so that it can fit within a vehicle cup holder. Thus, a user
will have oral care implements
100 available for use when the user is driving in the vehicle. Of course, the invention
is not so limited and the package
300 can take on other shapes and sizes, such as those disclosed above herein.
[0052] Referring to FIG. 6, an alternative arrangement of a package
600 of oral care implements is illustrated. The package
600 is identical to the package
300 except that the configuration of the inner walls and the film are different. The
portions of the package
600 that are the same as portions of the package
300 will be described with the same reference numerals, except that the 600-series of
numbers will be used. Any portions of the package
600 not specifically described herein have the same structure, configuration and use
as the same portions of the package
300.
[0053] The package
600 comprises a tubular body
601 having an annular wall
602 that forms a cavity
605 with a longitudinal axis
A-A. The package
600 comprises a plurality of radial walls
610 that divide the cavity
605 into a plurality of subcavities
606. The radial walls
610 extend radially from the longitudinal axis
A-A to the annular wall
602 such that each subcavity
606 is sealed from the other subcavities
606. In the exemplary arrangement, the package
600 has twelve radial walls
610 that divide the cavity
605 into twelve equally sized subcavities
606. Of course, the invention is not so limited and more or less than twelve radial walls
610 may be provided to divide the cavity
605 into more or less than twelve subcavities
606. Furthermore, in certain arrangements the radial walls
610 may divide the cavity
605 into a plurality of subcavities
606 of different sizes. As described above with respect to the package
300, the plurality of subcavities
606 may be of different sizes in order to store different types of oral care implements
within a single package
600. The number and size of the subcavities
606 are in no way limiting of the present invention.
[0054] Similar to the package
300, the package
600 has a film
620 enclosing a top end
608 of each of the subcavities
606. The film
620 is connected to a top edge
611 of each of the radial walls
610 and to a top edge
612 of the annular wall
602. Furthermore, in the exemplary arrangement, a portion of the film
620 that overlies and is attached to the top edges
611 of the radial walls
610 and the top edge
612 of the annular wall
602 is a pre-weakened portion
622 of the film
620. Of course, in certain other arrangements, the pre-weakened portion
622 of the film
620 may only be the portion of the film
620 that overlies the top edges
611 of the radial walls
610. In certain other arrangements, the film
620 may not have any pre-weakened portions
622, but may instead be a plurality of separate film segments as discussed above with
reference to the package
300. Thus, the package
600 is the same as the package
300 in all respects except for the configuration of the inner/radial walls
310, 610, and thus, the size, shape and number of the subcavities
306, 606. It is preferable that only one oral care implement
100 is disposed within each of the subcavities
606. However, the subcavities
606 are generally larger than the subcavities
306 and it may be possible to dispose more than one oral care implement
100 within each of the subcavities
606.
[0055] The film
620 may be penetrated as discussed above by providing a force onto the top surface of
one of the films
620 so that the film
620 breaks along the pre-weakened portions
622 surrounding the film
620. Alternatively, each of the film segments of the film
620 may include a tab for gripping by a user so that the film
620 can be separated from the top edges
611 of the radial walls
610 and the top edge
612 of the annular wall
602. Thus, the process of removing an oral care implement
100 from one of the subcavities
606 of the package
600 is the same as the process of removing an oral care implement
100 from one of the subcavities
306 of the package
600 discussed above with references to FIG. 3.
[0056] Referring to FIGS. 7 and 8, another comparative example, package
700 of oral care implements, is illustrated. The portions of the package
700 that are the same as portions of the package
300 will be described with the same reference numerals, except that the 700-series of
numbers will be used. Any portions of the package
700 not specifically described herein have the same structure, configuration and use
as the same portions of the package
300.
[0057] The package
700 comprises a tubular body
701 having an annular wall
702 that forms a cavity
705. The package
700 further comprises an inner wall
710 that divides the cavity
705 into two subcavities
706. Although the package
700 is illustrated having only a single inner wall
710, the invention is not so limited. In other arrangements, the package
700 may have two inner walls that are perpendicular to each other, or more than two inner
walls. The number of inner walls included with the package
700 is dependent upon the desired number of subcavities
706. A bottom end
704 of the package
700 is enclosed by a floor (not shown), which seals each of the subcavities
706 as discussed above with reference to the package
300.
[0058] The package
700 has a plurality of the oral care implements
100 disposed within each of the subcavities
706. For example, in the illustrated arrangement, ten oral care implements
100 are disposed within each of the subcavities
706. Of course, the invention is not to be limited by the number of oral care implements
100 disposed within each of the subcavities
706.
[0059] Each of the subcavities
706 has a top end
708 that is sealed by a re-sealable film
720. The re-sealable film
720 is attached to a top edge
711 of the inner wall
710 and a top edge
712 of the annular wall
702. More specifically, the re-sealable film
720 comprises two separate film segments
721 that are attached to the top edge
711 of the inner wall
710 and the top edge
712 of the annular wall
702 with a gap or space
723 between each of the film segments
721 at the top edge
711 of the inner wall
710. Thus, each one of the film segments
721 encloses and seals one of the subcavities
706. Of course, the invention is not so limited and in certain other arrangements the
film
720 may be a single film sheet that encloses both of the subcavities
706 and the film
720 may be a pre-weakened area as discussed above.
[0060] The film
720 is attached to the package
700 so that a portion of the film
720 can be manipulated to provide access into a single one of the subcavities
706, while the other subcavities
706 remain sealed. More specifically, one of the film segments
721 can be separated from the package
700 to expose/open one of the subcavities
706 while the other one of the film segments
721 remains attached to the package
700 so as to seal the other one of the subcavities
706. Of course, in embodiments where there are more than two subcavities
706, any one of the subcavities
706 can be opened while the other of the subcavities
706 remain sealed.
[0061] Each of the film segments
721 comprises a pull tab
724. The pull tabs
724 enable a user to easily grip the film segments
721 to manipulate the film segments
721 and open the subcavities
706, thereby exposing the oral care implements
100 within the subcavities
706 to the external environment. The pull tabs
724 are sized and shaped to be easily grasped by a user's fingers and thumb. The pull
tabs
724 also facilitate re-sealing of the film segments
721 as will be discussed below. Although the pull tabs
724 are illustrated as being located on the portion of the film segments
721 adjacent the top edge
712 of the annular wall
702, in other arrangements the pull tabs
724 can be located on the portion of the film segments
721 adjacent the top edge
711 of the inner wall
710.
[0062] The top edge
712 of the annular wall
702 and a portion of the top edge
711 of the inner wall
710 are covered or layered with an adhesive. Specifically, the top edge
711 of the inner wall
710 is covered with an adhesive while leaving the gap
723 between adjacent film segments
721 free of the adhesive. Additionally or alternatively, the adhesive may be applied
along a perimeter of each of the film segments
721. The adhesive is not applied to the pull tab
724 so that the pull tab
724 is prevented from adhering to the top edge
712 of the annular wall
702. Thus, a user will be more easily able to grasp the pull tab
724 and pull the film segments
721 of the film
720 away from the package
700 to open the subcavities
706. Furthermore, by giving a consumer a specific portion of the film segments
721 to pull, the consumer is not drawn to touching the adhesive portion of the film segments
721. Touching the adhesive portion of the film segments
721 may cause the adhesive layer to lose its adhesiveness and not provide a proper reseal
of the top ends
708 of the subcavities
706. Any type of adhesive that is now known or later discovered for use with re-sealable
films as described above may be used as the adhesive as would be known to persons
skilled in the art.
[0063] In use, a user will grasp the pull tab
724 of one of the film segments
721 and pull the film segment
721 away from the package
700 to open the subcavity
706. The bonding strength of the adhesive is strong enough to maintain a hermetic seal
when the film
720 is positioned on the package
700, but weak enough so that the seal can be broken to open the subcavities
706 without tearing or otherwise destroying the film
720. Once the subcavity
706 is opened, a user will remove one of the oral care implements
100 from the subcavity for use
706. The user can replace the oral care implement
100 back into the subcavity
706 for disposal after use. Then, the user will re-seal the film segment
721 to enclose and seal the subcavity
706 by reattaching the film segment
721 to the top edge
712 of the annular wall
702. The user can apply pressure to the perimeter of the film segment 721 in order to
ensure that a sufficient seal is achieved between the film segment
721 and the top edge
712 of the annular wall
702.
[0064] When the film segment
721 is pulled back from the package
700, the oral care implements
100 disposed within the subcavity
706 that was covered by the film segment
721 will be exposed to the external environment and therefore also to any moisture contained
therein. As noted above, it is desirable to prevent the oral care implements
100 from exposure to moisture prior to use in order to prevent premature rupture of the
gel capsules
132. However, it is most preferable that the oral care implements
100 be sealed during the packaging, shipping and display stages until sale to the end
user. In some arrangements, the oral care implements
100 are sealed. Once the end user purchases the package
700, limited exposure to moisture will not damage the oral care implements
100 or the gel capsules 132 disposed thereon. Thus, opening the package
700 and exposing a plurality of the oral care implements
100 to the external environment temporarily is not harmful to the gel capsules
132 of the oral care implements
100. However, it is preferable that the film segments
721 be properly re-sealed onto the package
700 in order to prevent excessive exposure of the unused oral care implements
100 to moisture.
[0065] Furthermore, creating the package
700 so that a desiccant can be disposed therein can further protect the gel capsules
132 of the oral care implements
100 against moisture damage. As discussed above, the oral care implements
100 in the package
700 will be subjected to the external environment prior to use because a plurality of
the oral care implements
100 are positioned within a single subcavity
706. As such, in certain arrangements, the package
700 may have a desiccant disposed therein as discussed above with regard to FIG. 5 in
order to absorb moisture that may potentially enter into the subcavities
706 during removal of a single one of the oral care implements
100 from the subcavity
706.
[0066] As discussed above with regard to the package
300, it may be beneficial to provide a lid for the packages described herein in order
to protect the films from damage or rupture. Referring to FIG. 9, one arrangement
of a package
900 having a lid
910 is illustrated. The package
900 may be any of the packages
300, 600, 700 discussed herein. The package
900 is therefore generically illustrated as comprising a tubular body
901 having an annular wall
902 that forms a cavity (not shown). The lid
910 may be any type of lid that is known to persons skilled in the art. The lid
910 does not need to hermetically seal the top end of the cavity because the film achieves
the hermetic seal as discussed above. In the exemplary embodiment, the lid
910 comprises a top plate
911 and an annular skirt
912. The lid
910 may be coupled to the tubular body
910 in any manner as would be known to persons skilled in the art. Because the package
900 is already sealed by the film (not shown), the lid
910 helps to protect the film from rupture prior to the time a user desires to use an
oral care implement disposed in the cavity. In certain other embodiments, the lid
910 may provide an additional hermetic seal by including a gasket to prevent moisture
in the external environment from penetrating into the cavity. The lid
910 may be attachable to the tubular body
901 by a press-fit, snap-fit, interference fit, friction fit or any other type of attachment/connection
as would be known to persons skilled in the art.
[0067] Referring to FIGS. 10 and 11, an embodiment of a package
1000 of oral care implements is illustrated. The package
1000 comprises a tubular body
1001 having an annular wall
1002 that forms a cavity
1005. The package
1000 also comprises a plurality of inner walls
1010 in the cavity
1005 that divide the cavity
1005 into a plurality of subcavities
1006. In the exemplified embodiment, the inner walls
1010 extend radially from a longitudinal axis
B-B of the cavity 1005. More specifically, the inner walls
1010 extend from the longitudinal axis
B-B to an inner surface
1013 of the annular wall
1002.
[0068] The annular wall
1002 comprises a plurality of slots
1030. Each of the slots
1030 forms a passageway into one of the subcavities
1006 from an area external to the subcavities
1006. In other words, the annular wall
1002 is made up of a plurality of wall segments
1032 that are separated by a gap formed by the slots
1030. Each of the wall segments
1032 is connected to one of the inner walls
1010 to form a T-shape.
[0069] The package
1000 comprises a roof
1003 that seals a top end
1008 of each of the subcavities
1006 and a floor that seals a bottom end
1009 of each of the subcavities
1006. The floor and roof
1003 may be integrally formed with the annular wall
1002 and inner walls
1010 or the floor and the roof
1003 may be separately formed and later connected to the annular wall
1002 and inner walls
1010 as has been discussed herein above. In the exemplified embodiment, the floor and
the roof
1003 are plates that enclose the bottom and top ends
1009, 1008 of the package
1000, respectively. However, the floor and the roof
1003 of the package may take on other structural forms as would be known to persons skilled
in the art so long as the floor seals the bottom ends
1009 of the subcavities
1006 and the
roof 1003 seals the top ends
1008 of the subcavities
1006.
[0070] At least one oral care implement
100 is disposed within each of the plurality of subcavities
1006. In the illustrated embodiment, exactly one oral care implement
100 is disposed in each of the twelve illustrated subcavities
1006. However, in certain other embodiments, more than one oral care implement
100 may be disposed in each of the subcavities
1006. Furthermore, the package
1000 may comprise more or less than twelve subcavities
1006 in alternative embodiments. The oral care implements
100 may be retrieved from the package
1000 through the passageway that is formed by the slots
1030 in the annular wall
1002.
[0071] In the exemplified embodiment, each of the subcavities
1006 is an open space between the annular wall
1002 and adjacent inner walls
1010. However, in certain other embodiments, the subcavities
1006 may simply be depressions in the annular wall
1002 that are sized and shaped to snugly fit a single oral care implement
100 therein. In other words, the annular wall
1002 may have a depression in an outer surface
1014 that is sized and shaped to correspond with the size and shape of the oral care implements
100. In such an embodiment, the oral care implements
100 can fit within the depression and be covered by a film as will be described in more
detail below. Furthermore, in such an embodiment, the inner walls
1010 may be omitted altogether because they will not be necessary to create the plurality
of subcavities
1006. Rather, in such an embodiment, the plurality of subcavities
1006 are the depressions formed in the outer surface
1014 of the annular wall
1002.
[0072] Each of the slots
1030 is sealed by a film
1020. As such, each of the subcavities
1006 is sealed from the external environment. Furthermore, the combination of the annular
wall
1002, the inner walls
1010, the roof
1003 and the floor seal each of the subcavities
1006 from the other subcavities
1006. Thus, each subcavity
1006 is its own, isolated and separate sealed compartment. The film
1020 is configured as discussed below so that a portion of the film
1020 can be manipulated to provide access into a single one of the subcavities
1006 while the other subcavities
1006 remain sealed. Specifically, the film comprises a plurality of film segments
1021 that are separable from one another. The film segments
1021 are connected to each other to collectively form the film
1020. The film
1020 comprises pre-weakened portions between adjacent film segments
1021, the pre-weakened portions overlying and attached to the outer surface
1014 of the annular wall
1002 to enable the film segments
1021 to be easily separated from each other so that access to one subcavity
1006 at a time can be achieved.
[0073] The film
1020 is attached to the outer surface
1014 of the annular wall
1002. More specifically, each of the film segments
1021 is attached to the roof
1003, the floor and two adjacent wall segments
1032 of the annular wall
1002. Furthermore, each of the film segments
1021 comprises a tab
1024. The tab
1024 extends from the film segments
1021 beyond the roof
1003 of the package
1000 for easy gripping by a user. Of course, the invention is not so limited and the tab
1024 could be otherwise located on the film segments
1021. Furthermore, the film segments
1021 could be attached to the package
1000 in other ways that would be known to persons skilled in the art as long as each one
of the film segments
1021 seals one of the subcavities
1006.
[0074] An adhesive is applied to either a rear surface
1025 of the film segments
1021 around the perimeter of the film segments
1021 or the outer surface
1014 of the annular wall
1002, or both. Thus, the film segments
1021 are removably attached to the outer surface
1014 of the annular wall
1002. A user can grasp the tab
1024 and pull down on the film segments
1021 in order to remove the film segments
1021 from the annular wall
1002 and to expose the subcavities
1006. Furthermore, in certain embodiments the film segments
1021 are re-sealable such that the film segments
1021 can be re-attached to the annular wall
1002 after opening in order to enclose and seal the subcavity
1006.
