Technical field
[0001] The present invention relates to a reinforced bottle crate suitable for being kept
by the end user and having a second life as a general purpose storage box. More in
particular, the present invention relates to a plastic crate which comprises a bottom
part, side walls and a divider element wherein the divider element is removably mounted
in the box and in that the bottom wall of the box is entirely closed.
Background art
[0002] Rectangular bottle crates such as beer crates, provided with a surrounding wall with
recesses as carrying handles, are widely known. Said bottle crates are usually provided
for being returned with the empty bottles.
[0003] Moreover, known bottle crates usually have a plurality of holes through their bottom
wall for purposes of air circulation, removal of humidity, yeast process, etc.
[0004] Such bottle crates are for example described in particular in
EP 0 322 152.
[0005] EP 0 322 152 discloses a crate having a body with a cavity for receiving a plurality of containers
and a base with floor surfaces containing openings on which the containers can be
supported. A crate insert is located in the cavity to provide a spacer arrangement
above the base of the body for separating containers in the crate from one another.
The crate body is a relatively thin-walled body of plastics material and the crate
insert has reinforcements for providing the body with support against flexing. The
crate body and insert have complementary formations for securing the insert to the
body, locating the insert and further strengthening the crate. The base of the crate
body is designed to rest on the tops or necks of containers in a subjacent crate for
nesting a plurality of crates.
[0006] There is room for improvement in these crates which, in themselves have already been
known for some time, or for crates suitable for being kept by the end user and having
a second life as a general purpose storage box.
Disclosure of the invention
[0007] It is an aim of this invention to provide an alternative bottle crate which is optimized
for a dual purpose, namely for storing and transporting bottles as well as for being
kept by the end user and having a second life as a general purpose storage box.
[0008] According to the present invention, the aforementioned aim is achieved with the bottle
crate showing the technical characteristics of the first claim. In particular, the
bottle crate is optimized for its first use in that the plastic box is an injection-moulded
plastic box, formed by a pair of longitudinal side walls, a pair of transverse side
walls and a bottom wall, the side and bottom walls being connected to each other at
right angles, at least one of the pairs of side walls being provided with handles,
the injection-moulded plastic box comprising reinforcement structures at the inside
of the side walls such that the box is capable of supporting a predetermined weight,
in particular the weight of like (or other) bottle crates and full bottles stored
therein which are stacked on top of the box, and furthermore in that the bottle crate
comprises a divider element which is provided defining storage spaces in the box for
storing bottles of a predetermined type and preventing that adjacent bottles of this
type that are stored in the box can contact each other. The "bottle crate" of the
invention is optimized for its second use as a general purpose storage box in that
the divider element can be removed and in that the bottom wall is entirely closed,
i.e. no holes are provided at the bottom of the box.
[0009] Further embodiments of the invention can be found in the depending claims and in
the description of the drawings.
[0010] In order to optimize the box for its second use, the reinforcement structures, which
are provided for reinforcing the walls of the box and help to provide the capability
of supporting the predetermined weight, are preferably purposely designed so that
they form minimal obstructions during the second use of the box. For example, the
reinforcement structures preferably comprise a plurality of first upright ribs provided
at the inside of the longitudinal side walls and spaced at substantially equal distances
from each other, so that the reinforcing function is well spread over the side walls
and that their dimensions can be minimized. As another example, the handles are preferably
provided on the transverse sides and the reinforcement structures comprise a plurality
of second upright ribs provided at the inside or outside of the transverse side walls
on opposite sides of the handles. As another example, the box preferably comprises
a support flange at the top side for supporting other crates stacked on top of the
box, with the reinforcement structures preferably not projecting more than this support
flange or in other words, considering the volume defined by this support flange by
orthogonal projection onto a virtual plane drawn on the bottom wall of the box, the
reinforcement structures are preferably fully provided in this volume.
[0011] Incidentally, an in-mould label may be provided on at least one of the side walls
and different in-mould labels may be provided on different side walls. Alternatively,
other types of labels or decorations may be provided on the side walls, such as for
example stickers, inserts, relief structures, other labels, screen printing, etc.
[0012] In an embodiment, the box is made of plastic material and preferably made of high
density polyethylene (HDPE) and/or polypropylene (PP) and/or polyethylene (PE). The
wall thickness of the side and bottom walls is preferably not more than 2.3 mm, and
more preferably not more than 2.0 mm. Preferably the wall thickness of the side and
bottom walls is as low as possible and determined as a function of the load which
has to be carried by the box.
[0013] In an embodiment, the box comprises integrated support structures on the inside of
side walls, provided for supporting the divider element at a predetermined height.
[0014] In an embodiment, said integrated support structures and the divider element are
together provided with resilient connection members, so that the divider element can
be releasably locked into place on the support structures. In this embodiment, the
divider element also functions as an additional reinforcement of the plastic box.
[0015] In an embodiment, the divider element is made of plastic material and preferably
made of high density polyethylene (HDPE) and/or polypropylene (PP) and/or polyethylene
(PE).

Modes for carrying out the invention
[0017] The present invention will be described with respect to particular embodiments and
with reference to certain drawings but the invention is not limited thereto but only
by the claims. The drawings described are only schematic and are non-limiting. In
the drawings, the size of some of the elements may be exaggerated and not drawn on
scale for illustrative purposes. The dimensions and the relative dimensions do not
necessarily correspond to actual reductions to practice of the invention.
[0018] Furthermore, the terms first, second, third and the like in the description and in
the claims, are used for distinguishing between similar elements and not necessarily
for describing a sequential or chronological order. The terms are interchangeable
under appropriate circumstances and the embodiments of the invention can operate in
other sequences than described or illustrated herein.
[0019] Moreover, the terms top, bottom, over, under and the like in the description and
the claims are used for descriptive purposes and not necessarily for describing relative
positions. The terms so used are interchangeable under appropriate circumstances and
the embodiments of the invention described herein can operate in other orientations
than described or illustrated herein.
[0020] The term "comprising", used in the claims, should not be interpreted as being restricted
to the means listed thereafter; it does not exclude other elements or steps. It needs
to be interpreted as specifying the presence of the stated features, integers, steps
or components as referred to, but does not preclude the presence or addition of one
or more other features, integers, steps or components, or groups thereof. Thus, the
scope of the expression "a device comprising means A and B" should not be limited
to devices consisting only of components A and B. It means that with respect to the
present invention, the only relevant components of the device are A and B.
[0021] The bottle crate 1 shown merely by way of non-limiting example in Figures 1 to 6
comprises a one part injection-moulded plastic box 2 and a one part injection-moulded
plastic crate divider element 3.
[0022] The box 2 is formed by a pair of longitudinal side walls 4, a pair of transverse
side walls 5 and a bottom wall 6, the side 4,5 and bottom 6 walls being connected
to each other at right angles. The transverse side walls 5 are provided with handles
7 formed by handle openings 8. Said handle openings 8 have rectangular shape and are
suitably reinforced by a peripheral rim 9 protruding inwardly. Hence, the crate can
be lifted easily. It is obvious that handle openings 8 can have any appropriate shape
such as ovoid shape, for instance, since the handle openings have dimensions such
that a hand can be inserted therein.
[0023] The bottom wall 6 is entirely closed in such way that the bottle crate according
to the invention is suitable for being kept by the end user and having a second life
as a general purpose storage box, said storage box being suitable for storing any
material, even capable of receiving solids and/or powdery and/or liquids. The inner
side of the bottom wall 6 is flat and the outer side, i.e. the lower side, of the
bottom wall 6 comprises nesting elements 10, which function for positioning like bottle
crates on top of each other and on which the bottle crate can stand when it is not
nested on another bottle crate. Said nesting elements 10 are formed by rectangular
or squared ribs 11 aligned longitudinally and transversely and spaced at substantially
equal distances from each other, so that the wall or top flange of another crate,
onto which the crate is stacked, can fit in between the ribs 11. In this embodiment,
the lower side of the bottom wall 6 comprises three longitudinal rows of four squared
ribs 11. It should be noted that the nesting elements 10 can have any appropriate
shape without departing from the scope of the invention.
[0024] The pair of longitudinal side walls 4 and the pair of transverse side walls 5 are
connected to each other at right angles through rounded corners 12 of the bottle crate
1. As shown, the surfaces of the side walls 4 and 5 are recessed with respect to these
corners 12, a top flange 13 and a bottom part 14. This is to protect labels or decorations
(not shown) that may be provided on the side walls.
[0025] Furthermore, the top end of the longitudinal side walls 4 and of the transverse side
walls 5 comprises a peripheral flange 13 extending perpendicularly to the longitudinal
side walls 4 and to the transverse side walls 5 of both sides of said walls 4 and
5. Said peripheral flange 13 forms a support flange at the top side of the box 2 as
a support surface for other bottle crates stacked on the top of the box 2. A first
portion of the peripheral flange 13 extends inwardly and a second portion of the flange
13 extends outwardly. The width of the peripheral flange 13 preferably lies within
the range going from 8 to 14 mm The peripheral flange 13 may have a different width
on different sides of the box 2.
[0026] In this embodiment, for example, the peripheral flange 13 does not have the same
width around the box 2. The flange 13 has a width of 12 mm on the long sides, i.e.
on the top of the longitudinal side walls 4, and a width of 8 mm on the short sides,
i.e. on the top of the transverse side walls 5. In this embodiment, the first portion
of the flange 13 extending inwardly has a width of about 8 mm along the top of the
longitudinal side walls 4. As mentioned above, the box 2 comprises also the nesting
structures 10 at the bottom side, which cooperate with this top flange 13 for positioning
the crates on top of each other.
[0027] Hence, the side walls 4 and 5 are recessed on the outside for decoration purpose.
Said decorations, not shown on the figures, are preferably in-mould labels but these
can also be stickers, laser printed decorations, relief structures on the side walls,
screen printing or any known type of decorations.
[0028] Moreover, the inner face of the longitudinal side walls 4 comprises reinforcement
structures such that the box 2 is capable of supporting a predetermined weight, usually
at least 100 kg. Said reinforcement structures comprise a plurality of first upright
ribs 15 provided at the inside of the longitudinal side walls 4 and extending from
the bottom wall 6 up the peripheral flange 13. Preferably, the first upright ribs
15 have a thickness which is smaller than, preferably substantially equal to, and
more preferably equal to the width of the first portion of the peripheral flange 13
extending inwardly, such that the first upright ribs 15 do not protrude from the peripheral
flange 13 inside the box 2.
[0029] In this embodiment, for example, said first upright ribs 15 are spaced at substantially
equal distance from each other. Said first upright ribs 15 have a thickness of about
8 mm which is equal to the width of the first portion of the peripheral flange 13
extending inwardly. Thus, said first upright ribs 15 do not protrude from the peripheral
flange 13 inside the box 2.
[0030] In the same manner, the outer face of the transverse side walls 5 comprises reinforcement
structures. Said reinforcement structures comprise two second upright ribs 16 provided
at the outside of the transverse side walls 5 and extending from the handle openings
8 to the peripheral flange 13. Said second upright ribs 16 have a thickness equal
to the width of the second portion of the peripheral flange 13 extending outwardly.
Thus, said second upright ribs 16 do not protrude from the peripheral flange 13 outside
the box 2.
[0031] Referring to figures 1 and 3 to 6, the box 2 comprises integrated support structures
17 on the inside of the longitudinal side walls 4, provided for supporting the divider
element 3 at a predetermined height. In this embodiment, said integrated structures
17 are pillars 18 extending from the bottom wall 6 up to about the mid-height of the
box 2. The divider element 3, provided for defining storage spaces in the box 2 for
storing bottles of a predetermined type and preventing that adjacent bottles of this
type that are stored in the box 2 can contact each other, is designed to be located
in the cavity of the box 2 at "shoulder height" of the bottles and has complementary
formations 19 for engaging formations 20 on the top end of the pillars 18 to locate
and releasably secure the divider element 3 with respect to the box 2. The complementary
formations 19 are hollow downright formations extending downwardly from the divider
element 3 and are designed to fit around top edges of pillars 18. Thus, complementary
formations 19 and formations 20 form resilient connection members so that the divider
element 3 can be releasably locked into place on the support structures. It should
be noted that the box 2 without the divider element 3 can also be used for selling
bottle packs, i.e. bottles packaged together in cardboard, without departing from
the scope of the invention.
[0032] Hence, the bottle crate according to the invention can be firstly used for selling
bottles, with or without the removable divider element, and then be kept by the end
user for a second life as a general purpose storage box, said storage box being capable
of receiving solids and/or powdery and/or liquids since the bottom wall of the box
is entirely closed.
[0033] The bottle crate according to the invention is preferably integrally formed and may
be made of suitable plastic material, such as polypropylene (PP), polyethylene (PE)
or high density polyethylene (HDPE) for instance. In the same manner, the divider
element 3 is preferably integrally formed and may be made of suitable plastic material,
such as polypropylene (PP) and/or polyethylene (PE) and/ or high density polyethylene
(HDPE).
[0034] Moreover, the bottle crate is preferably a standard crate of size 300x400 mm but
the principle of the invention can also be applied on non-standard crates, such as
for example half-size crates of 200x300 mm.
[0035] Furthermore, the bottle crate according to the invention is preferably a so-called
"light-weight" crate wherein the side walls 4,5 and the bottom wall 6 have a thickness
less than 2.3 mm, preferably less than 2.0 mm. The term "light-weight" means that
the weight of the box and the divider element together is not more than 1.5 kg, preferably
not more than 1.3 kg, more preferably not more than 1.1 kg, for a regular crate of
size 300x400 mm.
