Description
[0001] The said invention involves a multiple cavity crate for
containers such as yoghurt cups or similar, in accordance with the
characterizing clause of claim 1.
[0002] Such multiple cavity crates are used for the securing as
well as for the transport of food containers such as yoghurt cups,
cream cups etc. For this, loaded multiple cavity crates are stacked
on palettes and transported shrink-wrapped or in another manner as
well as stored in the establishment. These multiple cavity crates
must therefore ensure a sufficient amount of stability both in its
own structure as well as when stacked in order to prevent damage to
the food containers during transport.
[0003] A blank of foldable material for a multiple cavity crate is
known in DE 34 23 091 C2. For this, securing struts are
punched-out, raised and their respective ends are stuck together
during the folding out of the wall areas. The struts resulting from
this possess only a very limited rigidity, which can result in
damage to the food containers during the stacking of the individual
crates and/or during transport. In addition, it is costly to
arrange advertising prints on the inside of the crate.
[0004] A stackable crate is known from G 85 07 721.6, with which
the strut located in the inner-area is constructed in a similar
fashion by means of folding the external border areas inwards at an
angle of approx. 90.degree., whereupon each individual strut is
connected with the rest of the material. This design also has the
disadvantage of very limited rigidity and of a costly commercial
expansion of the external side of the folded crate. In addition,
the material utilization ratio of the crates mentioned is not
spectacular in comparison.
[0005] This said invention addresses the task of creating a novel
multiple cavity crate generic in nature, which ensures a
significantly improved level of rigidity featuring a greater ratio
of material utilization (reduction in material). In addition, the
multiple cavity crate is to provide load-relief for the
containers.
[0006] The said invention concerning the generic multiple cavity
crate is created in that at least one stabilizing strut connecting
the base with the upper-part is designated between at least two
rows of at least partially delimited cavities. Hence, the
stabilizing strut runs between two rows of cavities (with
interruptions if necessary) through the multiple cavity crate,
connecting the struts with one another. This consequently
guarantees bend-resistant rigidity, torsion-resistant rigidity and
rigidity parallel to the base plane, which is significantly greater
than that of the multiple cavity crates known that provide
stabilization solely in the border areas. In essence, the
stabilizing strut can run between two rows of cavities. It can also
be interrupted, in which case, the necessary stabilization is still
ensured. The invention allows for material savings of up to 40% in
comparison to the conventional blanks.
[0007] For practical purposes, the stabilizing strut is formed by
folding two foldable panels together, which pass through the blank
extending parallel to one of its sides.
[0008] The two foldable panels mentioned are then stuck together
after being unfolded for practical purposes. The stabilizing strut
in turn deals with a double-layer construction, which likewise
connects the base and the upper-part.
[0009] For practical purposes, areas belonging together are
staggered due to the folding of the foldable panels for the
production of the stabilizing strut--in consideration of the
condition of panels--whereupon these areas are positioned together
first through the folding of the foldable panels, that is, through
the creation of the stabilizing strut.
[0010] According to a design of the multiple cavity crate
corresponding to this invention, the blank comprises three foldable
panels, for which, two foldable panels located on the sides can be
folded to a middle foldable panel. Here, the foldable panels
located on the sides are connected with the respective struts
aligning them in such a way that space is generated between them
and the base through the folding of the struts.
[0011] A stabilizing strut is advantageously designated between
each row of cavities, through which an optimal rigidity can be
achieved.
[0012] Insofar the stabilizing strut is, in accordance with the
possible design of this invention, aligned with the blank such that
it runs parallel to the row of cavities with the greatest number of
cavities, an optimal ratio of material utilization results. The
foldable panels are connected to one another via a fold-line, e.g.
a line comprising perforations or a line with limited material
strength.
[0013] Furthermore, support straps, in accordance with another
design of the invention, can be designated in the area of the
stabilizing strut. These are directed upwards, that is, only on top
of neighboring crates located at the top of the stack and absorb as
well as transfer the force to the struts. As a result, the total
integrity of the stacked crates is improved and subsequent damage
of the good to be transported is avoided.
[0014] Another design of this invention is characterized in that
two stabilizing struts are designated adjacent to one another. As a
result, the rigidity of the struts is further increased on the one
hand and on the other, a set partition line can also be designated
between the two stabilizing struts such that the struts can be
twisted into smaller struts by means of a few manual
manipulations.
[0015] For practical purposes, neighboring foldable panels for the
respective stabilizing struts that feature such a partition line
are not connected such that the strut can only be separated along
the set partition line. Alternatively, the two neighboring foldable
panels along the set partition line are to be connected via
removable adhesives. When needed, they can be separated into
individual components using the set partition line. Thus, the
division of such struts into smaller struts can be carried out at
any time during the use of the struts with the invention-pursuant
multiple cavity crate, for example, by the buyer, the retailer
or--if desired--by the manufacturer prior to dispatch into the
retail market.
[0016] Furthermore, folds are designated in the corner area for
practical purposes. For these folds, two panels can be folded
together and connected, preferably using an adhesive. An increase
of the stability of the corners is consequently ensured.
[0017] The blank features a border area, which faces out when
folded with its upside corresponding to the upside of the base.
This allows for the commercial printing of the upper-part of the
base and simultaneously of the side area, which is visible from the
outside. As a result, the highly visible upper-portion of the blank
can be labeled.
[0018] For practical purposes, the upper-portion of the flat blank
is labeled, the upper-portion of the base, that is.
[0019] For practical purposes, a strap is strapped towards the top
and the neighboring strap on the outside downwards on the side of
the strut running perpendicular to the respective stabilizing
strut. Then both straps are stuck together after the staggering
achieved by erecting the crate has been fully completed. This also
generates a special reinforcement of the crate.
[0020] A partial strut can be designated between at least two
neighboring cavities in a row generating a special advantage. This
strut extends over a partial area transverse to the row of
cavities. As a result, the cavities are only partially delimited.
This produces a particularly high twist-resistant rigidity since
the base is not transversely interrupted. This has also the
additional advantage that the uninterrupted base is available for
commercial printing.
[0021] The partial strut can be connected to the base via a support
strut for practical purpose such that the partial strut is provided
with a stable footing. In addition, a multiplicity of partial and
support struts results in an increase of the general stability of
the multiple cavity box.
[0022] In essence, the support strut can run parallel to the
stabilizing struts. As a result, the support strut essentially runs
perpendicularly between the upper-part and the base, which in turn
produces an increase in the torsion-resistant rigidity parallel to
the base's plane. However, it is also possible that the support
strut runs diagonal to the upper-part and the base.
[0023] Protrusions can be advantageously designated in the area of
the upside particularly for the lateral-securing of a container.
These protrusions can be especially designated in the area of the
partial struts, thereby enabling the partial struts to fulfill a
double-function, that is, the securing of a container on one hand
as well as increasing the rigidity of the struts on the other. It
is particularly practical, if the protrusions feature a deformed
contour so that the containers inserted can be particularly well
stabilized in their position.
[0024] A crate utilizing the previously described partial struts is
characterized by its increased material savings of some 28% in
comparison to conventional crates.
[0025] The partial as well as the support struts can be arranged
such that they are positioned directly opposite one another within
a row of cavities, particularly in a row located on the inside.
This is advantageous in that the protrusions described above that
are located in the area of the partial struts equally stabilize the
inserted container in its position on both sides. The stability of
the entire crate can be thereby increased.
[0026] In contrast, the partial as well as support struts can only
be designated on the side of the border areas for rows of cavities
located along the border.
[0027] Another advantageous layout of the crate exists in that at
least one transverse stabilizing strut is designated transverse to
the stabilizing struts. The transverse stabilizing strut is
positioned essentially at a right angle to the stabilizing strut
and similarly runs between two consecutive rows of cavities. This
additionally increases the twist-resistant rigidity as well as the
carrying capacity of the multiple cavity crate to an even greater
extent.
[0028] The transverse stabilizing strut can be advantageously
removed along a set partition line. As needed, the multiple cavity
crate can be divided into smaller creates along the partition line
with a few simple manipulations. The foldable panels next to the
set partition line can, for example, only be connected in their
lower-area via a line comprising a perforation. In addition or
alternatively, the two foldable panels can be bonded together using
a removable adhesive. Likewise, a separation of the transverse
stabilizing strut can be conducted in the same manner as with the
stabilizing struts described above.
[0029] The crate's areas positioned on both sides of the transverse
stabilizing strut can be pivoted together such that the multiple
cavity crates can be positioned on top of a roof-shaped holder or
the like such that the two areas of the multiple cavity crate are
positioned diagonal one another, each consequently pointing in a
different direction. This can be advantageous to the presentation
of the containers held by the multiple cavity crate.
[0030] Furthermore, support straps can be designated in the area of
at least one part of the transverse stabilizing strut. These
support bars, which are bent upwards when the multiple cavity crate
is folded-up--like the support straps on the stabilizing struts
that were already described above--ensure the bracing of the
multiple cavity crate to the multiple cavity crate above. As a
result, a sufficient distance is maintained between the crates
positioned on top and the containers designated for the crate
positioned below and the containers are not damaged by the weight
of the crates positioned overhead.
[0031] In yet another advantageous design variation, a partial
strut is designed in the area of the partially delimited cavities.
This partial strut extends over a partial area transverse to a row
of cavities. This is advantageous in that the containers inserted
are protected in a particularly effective manner from shifting
within the partially delimited cavities and/or the respective
punch-out. Therefore, the partial struts have a reinforcing effect
within the multiple cavity crate on the one hand and on the other,
generate proficient gripping force of the containers within the
openings.
[0032] The respective partial strut is advantageously connected to
the base via a support strut. The support strut also leads to the
improved gripping of the containers as well as an increased
stabilization and twist-resistant rigidity of the entire crate.
Crates stacked on top also contribute to an even better gripping of
the containers.
[0033] For practical purposes, the partial strut and/or the support
strut can each be positioned in the middle of a partially delimited
cavity. This is advantageous in that the inserted containers are
equally stabilized in their position on both sides.
[0034] The support strut can advantageously run diagonally from the
partial strut inwards to the base, providing even better gripping
of the inserted containers and optimal protection from
shifting.
[0035] Furthermore, the width of the support strut can increase in
the direction of the base and be, e.g. trapezoid-shaped. This
layout also ensures a particularly stable footing for the
containers.
[0036] It is possible that the partial as well as support struts
are positioned directly opposite one another in every second row of
partially delimited cavities. For example, the partial and support
struts are only positioned directly opposite one another in the
rows located on the outside of a crate in order to make for a
symmetrical layout of the crate and an even distribution of force
particularly for containers inserted in the crate.
[0037] Another advantageous layout variation exists in that the
stabilizing strut is interrupted in sections at least on one side.
For this, the stabilizing strut only consists of partial struts
and/or foldable panel sections, which is sufficient for the
stabilization of the multiple cavity crate and serves to increase
the rigidity. This layout variant is advantageous because less
material is need and the multiple cavity crate becomes lighter.
[0038] The stabilizing strut can be completely interrupted in some
sections or only on one side especially alternating with the
bordering side such that, on the whole, a continuous stabilizing
strut is nonetheless present.
[0039] The stabilizing strut can be advantageous interrupted by
struts designated between the containers. The struts are therefore
worked out of the stabilizing strut and as such, constitute a
component of the upper-part.
[0040] For practical purpose, struts can also be designated in the
border area, between which the containers can be positioned. In
this case, the struts can be shaped at least in some sections like
the struts designated at the stabilizing strut such that the
containers inserted are stabilized both in the middle area as well
as in the border area in the same manner. The border area can be
additionally covered by means of a strap located on the side of the
border, which is combined with the remaining areas between the
struts and as such, extends between the base and the
upper-part.
[0041] Every two neighboring struts can advantageously form an at
least partially delimited cavity for holding a container. As a
result, the containers experience direct support by the struts such
that particularly effective grip is guaranteed.
[0042] The struts on the stabilizing strut facing both sides are
staggered with respect to one another in this layout variant such
that they remain firmly connected to the stabilizing strut. The
asymmetry generated by the staggering of the struts results in an
increase of the twist-resistant rigidity of the multiple cavity
crate. For this, the struts can be only slightly or also completely
staggered such that their sides bordering one another no longer
overlap.
[0043] For practical purposes, the struts at the two neighboring
stabilizing struts, particularly those parallel to one another
and/or the struts positioned at the stabilizing strut and those
positioned along the adjacent border area can be positioned
directly opposite one another such that the free standing strut
ends can be connected to one another, thereby mutually stabilizing
one another.
[0044] The struts can, in particular, overlap at their free end
areas such that they are combinable in a stable manner. For
example, the struts can be bonded together at their free,
overlapping end areas.
[0045] The struts opposite the stabilizing struts and/or those
opposite a stabilizing strut and the opposing border area also
cannot overlap one another, whereupon their free ends can each be
connected with the base using a connecting strap.

multiple cavity crate according to FIGS. 11a and b with inserted
containers.
[0060] Reference numeral 1 in FIG. 1 A denotes the flat blank for
the production of a first layout of the invention-accordant crate.
For practical purpose, this deals with material, which is provided
with appropriate punch-outs and/or partial punch-outs. The thickly
drawn, continuous lines rendered in FIGS. 1-7 denote punch-outs,
whereas thickly drawn lines interrupted by a continuous fine line
depict partial punch-outs for the creation of foldable lines.
[0061] The packing material blank features a base 2, which can be
seen in the top view of FIG. 1. This base 2 is covered with a full
or partial area commercial print not shown in this case. Areas (in
a flat state) are designated for base 2, which are designated as
upper-part 3 and are positioned at a height different to that of
base 2's plane following the folding-up of the blank for the
production of the multiple cavity crate. This upper-part 3
comprises individual struts 4, whereupon every two neighboring
struts 4 form a cavity for holding a container such as a yoghurt
container.
[0062] In the respective border area 5 of the blank 1, crooked
areas are similarly designated, which are positioned staggered to
the corresponding inner struts 4 in the blank's flat state. The
blank according to FIG. 1 features two stabilizing struts 7, which,
as shown in the representation from FIG. 1, each cross from one
side to the other transversing the blank 1. Every stabilizing strut
7 is formed between the foldable panels 8 and 9, whereupon the
foldable panel between the foldable panels 8 and 9 is drawn upwards
when folding the multiple cavity crate together in according with
FIG. 1B such that the two foldable panels 8 and 9 come into an
adjacent position. Another foldable panel 10, which connects the
strut 4 with the foldable panel 9, is folded over such that, in
according with FIG. 1B, the foldable line is located between the
foldable panel 10 and the strut 4, in this case at the same height
as the foldable line between the foldable panels 8 and 9. A
component of the stabilizing strut 7 is a somewhat foldable panel
20 roughly half as high locating at the beginning of the strut 4,
which is folded against the foldable panel 8.
[0063] Furthermore, an affixed foldable panel 21 from the base 2 is
folded against the border area 11 and bonded, if necessary.
[0064] When folding up the multiple cavity case according in the
manner previously described, the crooked areas of each of the
struts 4 located on the border's side and the crooked areas of the
border area 5 achieve the correct position with the dissolution of
the staggering and mutually form a cavity 6 for holding a (not
shown) container. The areas of the base 2 are rendered dotted in
FIG. 1B, since they are not cut.
[0065] In addition, the limited side areas 11, which are located
parallel to the reinforcing struts 7, are folded downwards by
90.degree. such that the printed side is visible from the
outside.
[0066] Furthermore, at least one part of the border straps (compare
with border strap 17) is folded downwards and--following the
dissipation of the staggering--adhered to the border strap 18 that
is folded upwards. In addition, the corner strap 19 is folded
around by approx. 90.degree. and likewise bonded to the border
strap 18.
[0067] In the area of each stiffening strut 7, a support strap
created by a cut-out 13 is located, which is bent upwards when the
crate is in a folded-up state. Said cut-out 13 ensures the support
of the multiple cavity crate with the neighboring multiple cavity
crate in the stacked network.
[0068] According to the second layout of the multiple cavity crate
presented in FIG. 2 that corresponds to this invention, two
stabilizing struts 7 are each designated to run transversely (comp.
FIG. 2 A). For this layout, every stabilizing strut 7 consists of a
foldable panel 8 as well as a foldable panel 9 whose connecting
fold-line is, following the folding out of the stiffening strut
and/or the struts into a plane, is located above the base 2 and/or
above the respective strut 4. An identically arranged stabilizing
strut 7 is alongside. Both stabilizing struts 7 are separated from
one another by means of a set partition line, e.g. perforated line
in FIG. 2A. In this case as well, the stabilizing struts 7 run
between the individual neighboring rows of cavities 6 for the
cut-outs.
[0069] This layout makes it possible that individual rows of the
multiple cavity crate can be separated when needed. For the layout
according to FIG. 2A, the corner straps 19 are bonded to the border
straps 18 folded upwards. The border area 11 is likewise, in
accordance with the representation in FIG. 2B, folded downwards by
roughly 90.degree. during the folding out of the multiple cavity
crate such that the commercial print is be seen easily from
outside.
[0070] The strut 4 is--see FIG. 2B--pushed upwards by folding the
two-sided foldable panels 20. The foldable panels 20 additionally
stabilize the stabilizing strut 7 as well as the border area 11.
The areas of the base 2 are drawn with dotted lines in FIG. 2B
since they are not cut. Only the one half of the arrangement of the
foldable panels, which form the stabilizing strut, is marked with
reference numerals in FIG. 2B for reasons of clarity.
[0071] A strap 16, which is connected with the base 2 and is folded
inwards by 90.degree., is located in the area of the border strap
18.
[0072] FIG. 2C shows a small, divided crate with only one row of
punch-outs 6 after separation of this crate from the arrangement
shown in FIG. 2A. This layout also features corner protrusions 12
for the improvement of the stackability of the entire multiple
cavity crate and/or of a divided multiple cavity crate.
[0073] The third layout of an invention-accordant multiple cavity
crate represented in FIG. 3 similarly features stabilizing struts 7
located adjacent to one another. These struts are formed by means
of the foldable panels 8 and 9 as well as the fold-line connected
these two foldable panels, which is located on the upside of the
Multiple cavity crate in an erected state. In addition, a set
partition line, also in this layout, is located between the two
stabilizing struts 7, which are setup as a double set partition
line due to the outer cone of the struts (previously described).
The corners are bonded on top of one another and with one another
by means of the corner folds 15 of two triangle foldable panels,
which additionally stabilizes this multiple cavity crate.
Especially stable multiple cavity crates can be made in this way.
Furthermore, the border straps 17 are folded down and the border
straps 18 are folded up and bonded together as well in this case.
The border area 11 and/or the commercial print located on top of it
are easily visible from outside due to similar downward folding for
the erected multiple cavity crate.
[0074] A divided multiple cavity crate smaller in size to the
previously mentioned is also visible in FIG. 3B. In additional, a
double row of cavities is intended in this case in contrast to the
previously described struts in accordance with the first and second
layouts.
[0075] FIG. 4A shows a fourth layout of the invention-accordant
multiple cavity crate. Here, two stabilizing struts 7 (also compare
with FIG. 4B), each of which consists of foldable panels 8 and 9
folded on top of one another and which are separated by a set
partition line 14, are likewise intended to be part of the design.
This likewise deals with a multiple cavity create featuring double
cavity arrangement on both sides of the stabilizing struts 7. The
multiple cavity crate features struts 4, which must be bonded to
one another after the crate is folded out in area 22. The mounts
for the struts 4 are (compare with FIG. 4B) are staggered with one
another in the base. Increased protection from ripping is
associated with this construct and the bonding. Likewise, corner
folding 15 takes place by means of a corresponding folding up of
the foldable panels located in the corner area as well as, if
necessary, their adhesion. The bonding of the side areas, that is,
border straps 17, 18 occurs in the manner described with the third
layout.
[0076] For the blanks shown in FIGS. 5, 6 and 7, the coarsely
hatched area (from above right to bottom left) represents the base
2, while the finely hatched area (from above left to bottom right)
represents the upper-part 3 in a folded-up state. The
perpendicularly arranged panels in the multiple cavity crate in its
folded-up state feature no hatching. A partial strut 23 is
designated between two partially delimited cavities 6 neighboring
each other in a row in the two layout examples from FIGS. 5 and 6.
This partial strut 23 extends over a partial area transverse to the
row of cavities 6. The strut provided with the reference numeral 4
in the FIGS. 1 and 2 is consequently no longer shown as a
continuous strut, but rather only runs over a partial area in a
transverse direction. As a result, the base 2 is no longer
interrupted for the centering of the containers and a commercial
print can be applied over a large area. Apart from that, the
continuous base leads to an increased twist-resistant rigidity in
the multiple cavity crate.
[0077] Some partial struts 23 are each connected with the base 2
via a support strut 24. The support struts 24 similarly increase
the rigidity of the entire struts. For this, the support struts 24
essentially run parallel to the stabilizing struts 7. The support
struts 24 can, however, absolutely also run diagonal to the
stabilizing struts and consequently be arranged diagonal to the
upper-part respectively to the base.
[0078] In the area of the upper-part 3, protrusions 25 are
designated particularly for the side gripping of a container. These
protrusions 25 feature a distorted contour for adjusting to the
external contour of the inserted container. The protrusions 25 are
also designed for both sides of the partial strut 23.
[0079] As can be gathered from FIGS. 5 and 6, partial 23 as well as
support struts 24, which are directly opposite one another, are
designated in the row of partially delimited cavities located on
the inside. In the rows of cavities 6 on the side of the border
alongside, the partial 23 as well as support struts 24 are only
designated for the side of the border areas. The partial as well as
support struts suffice for generating a high level of rigidity for
the struts.
[0080] The layout according to FIG. 6 will now be discussed. A
transverse stabilizing strut 7' is designated transverse to the
stabilizing struts 7. This transverse stabilizing strut 7' leads to
a further increase in the stability, twist-resistant rigidity as
well as the carrying capacity of the crate.
[0081] For the blank depicted in FIG. 8a, the coarsely hatched area
represents the base 2, while the fine hatched area stands for the
upper-part 3 in a folded-up state.
[0082] The transverse stabilizing strut 7' can be separated along a
set partition line 26. The set partition line 26 is designed as
perforation such that the two areas of the multiple cavity crate
can be separated from one another easily. This facilitates above
all the division of the crates into smaller units.
[0083] The transverse stabilizing strut 7' is formed through the
folding together and bonding of each set of two transversely
running border areas 11 arranged on both sides of the transverse
stabilizing strut 7'. The transverse stabilizing strut 7' in
particular is kept intact by a connection of the neighboring border
regions 5 and/or border straps 17 and 18 as well as the corner
straps 19 of the areas arranged on both sides of the transverse
stabilizing strut 7'. The two areas on both sides of the transverse
stabilizing strut 7' can also only be connected with one another
such that they can be pivoted together. For this, the two areas
along the transverse stabilizing strut 7' are only connected with
one another in terms of lines. In the area of the transverse
stabilizing strut 7', support straps 27 are additionally
designated. These straps ensure that the necessary space to the
crate positioned overhead is maintained.
[0084] For the blank depicted in FIG. 7, the partial struts 23 are
designated in the area of the partially delimited cavities 6,
whereupon the partial struts 23 extend over a partial area
transversely to a row of cavities 6. In this case as well, the
partial strut is connected to the base 2 via a support strut 24.
The arrangement of the partial struts 23 as well as the support
struts 24 in the area of the cavities 6 results in the inserted
containers being effectively secured against shifting laterally. In
addition, the partial struts 23 in connection with the support
struts 24 also affect a stiffening of the multiple cavity
crate.
[0085] The partial struts 23 as well as the support struts 24 are
each positioned in the middle of a partially delimited cavity 6 in
order to stabilize the inserted containers equally on both
sides.
[0086] In the folded-up state, the support strut 24 runs inwards
diagonally from the partial strut 23 to the base 2, thereby
provided for even better gripping of the inserted containers on the
one hand, while on the other hand these containers can still be
easily removed from above.
[0087] The width of the support struts 24 increases in the
direction of the base 2, whereupon the support struts located on
the inside 24 exhibit the shape of an equilateral trapezoid. The
widening of the support struts 24 in the direction of the base 2
generates a further improvement in the gripping of the
containers.
[0088] As further gathered from FIG. 7, the partial 23 as well as
support struts 24 are positioned in each of the outward-facing rows
of partially delimited cavities 6, while no support struts 24 are
designed in the middle row in order not to weaken the stabilizing
strut 7 through excessive interruptions in its stability and/or
integrity.
[0089] The layout depicted in FIG. 8a and b will now be described.
For this multiple cavity crate, the stabilizing strut 7 is
interrupted in sections. This design, in contrast to the example
layout from FIG. 1A, enables the saving of even more material and
the reduction of the crate's weight.
[0090] The stabilizing strut 7 is formed by means of several and/or
two foldable panel sections 30 that are to be bonded together and
is interrupted by the struts 4 designated for between the
containers, which are located between the foldable panel sections
30. In addition, a particularly twist-resistant multiple cavity
create is produced through the connection of the individual
foldable panel sections 30 to the upper part 3 by means of the
neighboring struts 4. Apart from that, a particularly compact
design of the multiple cavity strut is consequently achieved.
[0091] Struts 4' are designated along the border area, between
which the containers can be positioned. In contrast, the border
strap 28 is designed without interruptions, thereby providing for a
stable border area.
[0092] Every two neighboring struts 4 respectively 4' form at least
one partially delimited cavity 6 for the reception of a container.
The containers consequently rest against the edge of the cavities
and are secured in this manner.
[0093] The struts 4 on the stabilizing strut 7 that point to both
sides are staggered with respect to one another such that they are
mounted on the stabilizing strut 7. The staggered arrangement of
the struts 4 results furthermore in a high twist-resistant rigidity
above all in the area of the stabilizing strut 7.
[0094] The struts 4 and 4' positioned opposite one another are
located on the one hand at the stabilizing strut 7 and on the other
at the adjacent border area such that their free end areas 29 can
be connected with one another. For this, the struts 4 and 4'
overlap at their free end areas 29 (see FIG. 8b) and are bonded
together in the overlapping area.
[0095] In the FIGS. 9 to 11b, the base 2 is represented by a
cross-hatched area, while the upper-part 3 is characterized by a
hatched area. The areas that essentially run perpendicularly, the
stabilizing strut 7, among others, are not hatched. The multiple
cavity crate featured in FIGS. 9 and 10 is designed to hold twelve
containers and/or cups, while the layout from FIG. 11 can be loaded
with twenty cups 33. (see FIG. 1c).
[0096] For the layout of the multiple cavity crate featured in FIG.
10, stacking corners 34 are designed in contrast to FIG. 9. These
stacking corners serve to improve the stackability of the multiple
cavity crate. For the layouts of the multiple cavity crate depicted
in FIGS. 9 to 11, the struts 4 are staggered with respect to one
another such that the stabilizing strut 7 is only interrupted on
one side by the upwards-folded struts 4. The foldable panel
sections 30 remaining between the struts 4 are bonded to one
another at the stabilizing strut 7. This design ensures a
significant savings of material as well as very good mechanical
integrity and/or twist-resistant rigidity. The struts 4 opposite to
one another at the stabilizing struts 7 as well as the struts 4, 4'
positioned on one hand at the stabilizing strut 7 and on the other
at the adjacent border area are not located directly opposite. The
end areas 31 of these struts 4, 4' are therefore connected with the
base 2 via a connecting strap 32.
[0097] In FIG. 9, a stabilizing strut 7 is designated, while two
stabilizing struts 7 positioned parallel to one another are
integrated in FIG. 10.
[0098] From a comparison of FIGS. 11a and 11b, the folding together
and/or the erection of the multiple cavity crate from the blank 1
are particularly well depicted.
[0099] It is noted that all features of the previously described
layouts can also be swapped among one another. The
invention-accordant multiple cavity crate features a significantly
improved rigidity on the one hand and on the other, an improved
ratio of material utilization. In addition, the production costs
(such as printing and punch-outs) can be reduced by up to 50%
because more uses (e.g. thus far three uses, now six uses) are
possible on the printed sheet. What's more, only limited punching
ejection falls into the outer area. The invention-accordant blank
is therefore particularly suited to rotational punching as well.
The invention therefore represents a fully decisive advance in the
applicable area.
