Abstract
A carton for foodstuff, in particular for pizzas or similar
foodstuffs, comprises a bottom part (2) and a lid part (3). Each of
these parts (2, 3) has a front wall (4, 5) and two side walls (6,
7, 8). Bottom part (2) and lid part (3) are joined together
pivotally by a rear wall (10) so that these parts (2, 3) are
pivotable for opening and closing the carton (1). To stack cartons
stably on top of one another in a simple manner and to prevent
jamming of cartons arranged one above the other, at least one front
wall (4, 5) of the bottom part (2) or lid part (3) runs obliquely
outwards corresponding to a free end edge (11, 12) of the at least
one front wall (4, 5).

Description
CROSS REFERENCE TO PRIOR APPLICATIONS
[0001] This is a U.S. National Phase application under 35 U.S.C.
.sctn.371 of International Patent Application No.
PCT/EP2011/005177, filed Oct. 14, 2011, and claims the priority of
German Patent Application No. 20 2010 014364.0, filed Oct. 15, 2010
both of which are incorporated by reference herein in their
entirety. The International Application published in English on
Apr. 19, 2012 as WO 2012/048898 under PCT Article 21(2).
[0002] The invention relates to a carton for the temporary storage
of a foodstuff, such as particularly a pizza or similar foodstuff.
A generic carton is known for example from U.S. Pat. No. 7,051,919.
The carton is folded from a blank and lies ready to accommodate,
for example, a pizza or similar foodstuff. The pizza in a hot state
is put into the carton which is then closed. Generally, a large
number of such cartons are needed into which pizzas are
continuously placed and, after closing the carton, for example,
transferred to the customer.
[0003] An appropriate carton has a bottom part and a lid part. Each
of these parts generally comprises a front wall and two side walls,
which protrude appropriately from a bottom wall or a lid wall. For
opening and closing the carton a bottom part and a lid part are
joined pivotably together. The appropriate pivot joint is realised
by a rear wall. In this way the bottom part and lid part can be
arranged both in an essentially horizontal arrangement adjacent to
one another, i.e. as an open carton, and one over the other, when
the carton is closed.
[0004] When baking appropriate pizzas generally a plurality of
pizzas are ready essentially simultaneously and must be placed into
appropriate cartons. To achieve this, these cartons are arranged
adjacently.
[0005] An arrangement of cartons of this nature next to one another
requires much space which is often not available in the vicinity of
an appropriate oven for pizzas. If open cartons are arranged one
above the other, the resulting stack is not very stable or leads to
the jamming of cartons stacked on top of one another.
[0006] The object of the invention is to stack cartons stably on
top of one another in a simple manner and also to prevent jamming
of cartons arranged one above the other.
[0007] The object is solved by the carton of the present invention.
According to the invention at least one front wall of the carton
runs from the bottom or lid part outwards to a free end edge of the
corresponding front wall.
[0008] It is sufficient if, for example, the front wall of the
bottom part runs obliquely outwards in an appropriate manner.
Through this simple measure, stacking of appropriate cartons is
possible in a stable manner without them becoming jammed.
[0009] Here, it is furthermore sufficient if only one appropriate
end section of the front wall runs outwards with a slope of this
nature.
[0010] It must be noted that generally the appropriate carton is
already partly appropriately folded only in the region of the front
walls of the bottom part and lid part, whereas the associated side
walls are already partly defined only in the region of these front
walls, whereas they can still be deflected elastically outwards in
the direction of the rear wall.
[0011] In this way appropriately opened cartons can be stacked in a
simple manner one on top of the other, whereby they are at least
partly stacked nested in one another and without jamming.
[0012] In this connection there is the possibility that both front
walls, both of the bottom part and of the lid part are sloped
outwards by the same angle. However, it is also conceivable that,
for example, one of the front walls is sloped outwards by a smaller
angle than the other front wall.
[0013] Since the pizza is placed on the corresponding bottom wall
of the carton, jamming of stacked cartons particularly in the
region of the bottom parts is to be more expected than in the
region of the lid parts. In order to be able to prevent jamming of
this nature in a simple manner an upper recess is formed at least
between upper end sections of the front wall of the bottom part and
the associated side walls. This recess facilitates a further and
particularly elastic outward pivoting of the appropriate front wall
at least in the upper end section, which simplifies stacking of the
cartons.
[0014] The upper recess can have different shapes, whereby it can
be favourable if the upper recess has a width which increases in a
direction towards the free end edges of the front wall and side
walls.
[0015] A recess of this nature can for example be formed
essentially V-shaped.
[0016] In order to obtain sufficient stability with a closed
carton, it may be regarded as advantageous if the front wall has a
two-part structure comprising a first front wall section and a
second front wall section. The first front wall section is joined
to the bottom or lid part. The second front wall section is joined
pivotably to the first front wall section. In this way there is the
possibility of folding the second front wall section relatively to
the first front wall section into the carton interior and
consequently obtaining a double-layered front wall.
[0017] In order to support the corresponding front walls in their
sloped position the side walls can have oblique first end edges
which are assigned to the corresponding front wall. A corresponding
oblique angle of these edges is essentially equal to the oblique
angle of the front wall. In this way the front wall is overall
arranged obliquely, whereby this slope is supported by the
corresponding oblique angles of the end edges of the side
walls.
[0018] In order to be able to join the side walls to the
double-layered front wall in a simple manner the corresponding end
edge of each side wall can be joined to an end lug folded
especially inwards. This end lug can abut an inner side of the
first front wall section.
[0019] This means that the corresponding end lug is arranged
between the first front wall section and the second front wall
section of the corresponding front wall, whereby it can be inserted
between them on folding the carton together.
[0020] The corresponding upper recesses are partly formed by the
first recesses between the upper end sections of the end lugs and
the side walls in order to provide an appropriate free space for
the stacking of cartons arranged one above the other.
[0021] A further second recess is formed between lateral edges of
the first and second front wall sections which on folding together
the two front wall sections combine with the corresponding first
recess to form the upper recess.
[0022] The corresponding oblique angles are in a range from
94.degree. to 110.degree. and advantageously can lie in a range
from 98.degree. to 104.degree..
[0023] When folding the second front wall section relative to the
first front wall section, folding is simplified if the two front
wall sections are joined together by means of an articulated strip.
The front wall sections can be pivoted relative to one another
about appropriate strip edges so that the second front wall section
can be folded down in a simple manner towards the carton interior
and relative to the first front wall section.
[0024] Lateral edges of the articulated strip can form a bottom of
the second recess which is visible especially on the appropriate
blank for the carton.
[0025] In the direction of the second recess the lateral edges of
the front wall sections run obliquely outwards.
[0026] A free longitudinal edge of the second front wall section
can have an appropriate protrusion which, with the second front
wall section folded inwards, can be inserted into a groove in the
bottom or lid part. In this way the arrangement of the second front
wall section folded inwards is secured and the second front wall
section essentially abuts the first front wall section from
inside.
[0027] The corresponding groove can extend along a fold line which
joins together the first front wall section and the bottom and lid
parts. In this way close abutment of the first and second front
wall sections is produced.
[0028] Good pivotability, for example, of the lid part relative to
the bottom part and simple closure of the carton can be produced in
this way if the bottom part and lid part are both pivotably joined
to the rear wall. In this way a good horizontal arrangement of the
open carton is produced in which essentially the rear wall can also
be arranged horizontally.
[0029] In order to stabilise the closed carton in the region of the
rear wall, the rear wall can have rear wall lugs which are
especially pivotably joined to appropriate sideward rear-wall end
edges.
[0030] The arrangement of the side walls of the bottom and lid
parts can occur in a manner such that they can be splayed out
elastically to the outer side of the carton especially during
stacking. This splaying out is especially produced along the side
walls in the direction of the rear wall with the carton open.
[0031] Through simple insertion of the appropriate end lugs, the
side walls can however also be splayed outwards in the region of
the front walls.
[0032] This splaying out of the side walls supports the
jamming-free stackability of appropriately opened cartons.
[0033] End edges of the side walls, especially in the region of the
rear wall, can be rounded to simplify closure of the carton.
[0034] It has already been pointed out that the second front wall
sections can be fixed in the folded position. In an analogous
manner the carton can also be at least partially secured in its
closed position in that the first front wall section of the bottom
or lid part has a locking extension which is appropriately aligned
to the lid or bottom part with the carton closed.
[0035] In order to accommodate the locking extension in this closed
position, the lid or bottom part appropriately can have a locking
groove for insertion of the locking extension.
[0036] In order to prevent the hot pizza losing its crispness due
to moisture that it produces and being detrimentally influenced in
its consistency for consumption, the first front wall section can,
for example, have two or more openings. Appropriate moisture can
emerge out of the closed carton through these openings. With the
carton closed the openings in the second front wall sections of the
bottom and lid parts are aligned to one another.
[0037] However, in order to prevent cooling of the pizza occurring
by means of these openings as well as the emergence of moisture,
the openings of the first front wall sections in the direction
towards the carton interior are covered by the second front wall
sections.
[0038] In this way an adequate emergence of moisture is ensured,
but excessive cooling of the pizza is prevented.
[0039] The invention also relates to a corresponding blank for the
manufacture of the carton described above.
[0040] In the following, an advantageous embodiment of the
invention is explained in more detail based on the figures enclosed
in the drawing.
[0041] The following are shown:
[0042] FIG. 1 a perspective plan view from diagonally above onto a
closed carton according to the invention;
[0043] FIG. 2 cartons stacked inside one another in the open
position and
[0044] FIG. 3 a plan view of a blank for a carton according to the
invention.
[0045] FIG. 1 shows a perspective view of a carton 1 according to
the invention. It is illustrated in the closed state. That is, a
locking extension 52, which--refer also to FIG. 2--protrudes from a
front wall 4 of a bottom part 2, is inserted into an appropriate
locking groove 53 in the lid part 3. To the side adjacent to the
locking groove 53 two further grooves 44 are arranged, into which
protrusions 43 are inserted which are used for fixing a second
front wall section 21 or 23--refer also to FIG. 3--in the folded
state relative to the associated first front wall section 20,
22.
[0046] The carton 1 according to FIG. 1 is essentially cuboid and
is used for the storage of a foodstuff, essentially a pizza or
similar foodstuff. The relatively flat foodstuff is placed into the
carton and can be transported by means of it.
[0047] Two openings 55 are formed in the first front wall section
20 of a front wall 5 of the lid part 3. They are covered from
inside, i.e. from the carton interior, by the associated second
front wall section 21, refer also to FIG. 3.
[0048] For further description of the carton according to FIG. 1
reference is made to the embodiment in FIGS. 2 and 3. The same
parts are in each case described using the same reference numerals
and are in part only explained in more detail in conjunction with
one of the figures.
[0049] FIG. 2 shows a perspective plan view from diagonally above
onto two open cartons 1 with one stacked inside the other.
[0050] Each of the cartons 1 has a bottom part 2 and a lid part 3.
They are pivotable relative to one another, whereby the
pivotability occurs by means of a rear wall 10. On this the bottom
part 2 and lid part 3 are pivotably supported and joined to one
another by it. On the ends at the side--refer also to end edges 48
and 49 in FIG. 3--rear wall lugs 46 and 47 are joined pivotably to
the rear wall 10.
[0051] The bottom part 2 has appropriate side walls 6 and 7 as well
as a front wall 4. The front wall 4 is formed from two front wall
sections, refer to the first front wall section 20 and second front
wall section 21. Analogously, the lid part 3 is formed from
appropriate side walls 8, 9 and the front wall 5 in each case with
the first front wall section 22 and the second front wall section
23. In addition the bottom part 2 and the lid part 3 also have
appropriately a bottom part 57 and a lid part 58.
[0052] The upper end sections 15 or 16 of the front wall 4 of the
bottom part 2 or of the associated side walls 6, 7 are separated
from one another by the upper recesses 14. They are essentially
V-shaped and in the direction towards the free end edges 18, 11
have increasing width 17. By means of this upper recess 14 at least
the upper end section 15 of the corresponding front wall 4 or also
of the analogous upper end section 16 of the side walls 6, 7 can be
splayed outwards.
[0053] The corresponding front wall sections 20, 21 or 22,
23--refer also to FIG. 3--are joined together using an articulated
strip 19. This forms an appropriately free end edge 11, 12 of the
front walls 4, 5. The articulated strip 19 is interrupted
approximately in the middle on the front wall 4 of the bottom part
2, whereby here the corresponding locking extension 52 protrudes
from the first front wall section 20.
[0054] Furthermore, the first front wall section 20 or also the
first front wall section 22 of the lid part 3 has two openings 54
respectively 55 which are spaced from one another. Towards the
carton interior they are covered in each case by the second front
wall section 21 respectively 23.
[0055] Along the side walls 6, 7 respectively 8, 9 it can be seen
that they are also outwardly elastically deflectable in the
direction of the rear wall 10. Together with the slope of the
corresponding front walls, this supports the stackability of the
opened cartons.
[0056] The stacked cartons 1 according to FIG. 2 are placed ready
for filling with pizzas, so that appropriately in each case a pizza
can be placed in position on the bottom wall 57 once it has been
produced. Then the filled carton 1 is removed from the carton stack
still in the open state and closed, refer also to FIG. 1. In the
closed state it can then be transported and in particular passed on
to a customer. The open carton with the pizza in place can be
easily removed from the carton stack without the stacked cartons
jamming together.
[0057] FIG. 3 shows a plan view of an appropriate blank 56 for the
manufacture of a carton according to FIGS. 1 and 2.
[0058] The blank for the bottom part 2 is shown appropriately in
the right half of FIG. 3 and the lid part 3 is shown in the left
half. The bottom part 2 comprises the bottom wall 57 with side
walls 6, 7 protruding from it and a first and second front wall
section 20, 21. Apart from the second recesses 32, 33 and the
locking extension 52, the front wall sections 22, 23 of the lid
part 3 are analogous to the first and second front wall sections
20, 21 of the bottom part 2. Two protrusions 43 are arranged--refer
also to the second front wall section 21--along a free longitudinal
edge 52 of the second front wall section 23. They can be inserted
into corresponding grooves 44 with the second front wall section 23
folded inwards. This can be seen for example also in FIG. 1. An
articulated strip 19 is arranged in each case between the two front
wall sections so that they are pivotable relative to one another.
Along appropriate strip edges 38, 39 the respective second front
wall section 21 or 23 can be folded over the first front wall
section 20 respectively 22 towards the carton interior.
[0059] Corresponding lateral edges 34, 35 of the front wall
sections run at an angle outwards towards one another and in
particular in the direction of the second recesses 32 and 33 on the
front wall sections 20, 21 of the bottom part 2. The appropriate
angle is for example 93.degree..
[0060] The respective first front wall section 20 or 22 can be
folded relative to the bottom wall 57 or lid wall 58 about an
appropriate bending or fold line 45, refer for example to FIGS. 1
and 2, whereby the grooves 44 or locking groove 53 appropriately
extend along this bending or fold line 45.
[0061] An angle between this bending or fold line 45 and an
appropriate bending line along the side walls is 90.degree..
[0062] The bottom wall 57 is joined to the lid wall 58 by the rear
wall 10. At its end edges 48, 49 it has foldable rear wall lugs 46
or 47. The associated side walls 6, 7, 8, 9 are bent in the region
of these rear wall lugs 46 and 47, refer to the corresponding end
edges 50 and 51.
[0063] Oppositely situated end edges 24 or 25 run forwards at an
angle in the direction towards end lugs 27 and 28. An appropriate
oblique angle 13, 26 can be, for example, 101.degree..
[0064] The end lugs 27, 28 can be folded inwards, refer to FIG. 2,
whereby they can be arranged between the front wall sections 20, 21
respectively 22, 23 and can be inserted into them, so that they
abut an inner side 29 of the front wall sections.
[0065] The first recesses 30 respectively 31 are formed between the
side walls 6, 7 and upper end sections 36, 37 of the associated end
lugs 27, 28. They are essentially V-shaped and extend outwards,
whereby the corresponding V tip is aligned to the end edges 24 or
25.
[0066] Between the first front wall section 20 and the second front
wall section 21 in the region of their lateral edges 34 and 35,
analogous second recesses 32 and 33 are arranged. They are also
essentially V-shaped, whereby an appropriate V tip is formed by the
end edges 40 or 41 of the articulated strip 19. In this way the
second recess 32 or 33 has a bottom 59.
[0067] The second front wall section 21 can be folded inwards,
refer to FIG. 2, by means of which appropriately the upper free end
edges 11 or also 12--refer again to FIG. 2--are formed by the
articulated strip 19. After the appropriate folding over or inwards
of the second front wall section 21 relative to the first front
wall section 20 the locking extension 52 protrudes, refer to FIGS.
1 and 2. With the carton closed, it can be inserted into the
locking groove 53.
[0068] An appropriate angle between the bending or fold line 45
between the bottom wall 57 and the first front wall section 20 and
the lateral edge 34 of the first front wall section 20 can be, for
example, 93.degree..
[0069] The corresponding first recesses 30, 31 are delimited by the
end edges 24, 25, which appropriately form the end section 16,
refer to FIG. 2. The further end section 15 according to FIG. 2 is
formed by the second recesses 32, 33 after folding the first front
wall section 20 and the second front wall section 21 together.
[0070] From FIG. 3 it can also be seen that with the front wall
sections 21 or 23 folded inwards they cover the corresponding
openings 54, 55 of the first front wall sections 20 or 22.
[0071] It can also be seen from FIG. 3 that the corresponding side
walls 6, 7 of the bottom part 2 are arranged offset inwards in the
direction of the bottom wall 57 relative to the side walls 8, 9 of
the lid part 3. The appropriate fold lines between the side walls
and associated bottom wall or lid wall are also arranged mutually
offset, whereby the side walls 8 and 9 of the lid part 3 protrude
slightly further outwards and are essentially flush with the free
end edges of the rear wall lugs 46 and 47.
[0072] Due to the corresponding slopes of the end edges 24 or 25,
the front walls 4, 5 are also sloped outwards, refer in particular
to FIGS. 1 and 2. Here, in particular in the region of the front
wall 4 of the bottom part 2, there is the possibility in particular
of widening the upper end sections 15 still further outwards. In
this way overall the stackability of the opened cartons 1 without
jamming is obtained, refer to FIG. 2. An analogous slope of the
front wall 5 of the lid part 3 is also provided.
[0073] Furthermore, the corresponding side walls 6, 7, 8 and 9 can
in particular be splayed elastically outwards in the direction
towards the rear wall 10, refer also to FIG. 2.
[0074] In the following the use of the carton according to the
invention is briefly described.
[0075] The cartons are kept stacked ready in an open position
analogous to FIG. 2. Due to the formation in particular of the
front walls stacking without jamming is provided which is supported
by the elastic splaying out of the side walls. In the arrangement
according to FIG. 2 a pizza is in each case placed on the
corresponding bottom wall. The open carton can then be removed from
the stack without jamming in the cartons located below and closed
by means of folding over the lid part, refer also to the engagement
of the locking extension 52 in the locking groove 53 according to
FIG. 1. In this way pizzas can be continuously placed into
appropriate cartons which can be removed from the stack of cartons
and then closed. Consequently, less space is required and jamming
of the stacked cartons does not occur.
