Description
[0001] The present invention is related to a container carrier made
of cardboard.
[0002] Container carriers made of cardboard are used for storing
and transporting bottles or cans, in particular For this purpose,
the container carriers have a bottom wall, side walls standing up
from the longitudinal sides of the bottom wall and side walls
standing up from the transverse sides of the bottom wall.
Preferably, they have a handle for carrying in addition. For
instance, the latter is formed by several grip-in openings in side
walls or by one grip-in opening in an intermediate wall standing up
between the side walls. But it may also be a strip-shaped handle
portion, bridging the distance region between two side walls.
Further, there are container carriers which are closed at the top
by a top wall which is connected to side walls at its edge side.
The handle is formed by at least one grip-in opening in the top
wall, for instance. In known realisations, there are two grip-in
openings spaced apart from each other through which a strip-shaped
portion of the top wall arranged between them can be grasped.
Further, the handle may be formed by a portion that can be pulled
out, delimited by punching lines in the top wall and, as the case
may be, in adjacent regions of side walls. Further, container
carriers are known in which the bottom wall, two side walls and as
the case may be the top wall are connected by creasing lines on
their long sides and which are glued together in overlapping
regions. The pre-glued blank can be set upright to a wrapper with
openings at the transverse sides. Additional side walls are formed
by bottom wall flaps, which are articulated on the transverse sides
of the bottom wall, side wall flaps which are articulated on the
transverse sides of the side walls, and as the case may be top wall
flaps which are articulated on the transverse sides of the top
wall. The side wall flaps, bottom wall flaps and as the case may be
top wall flaps are collapsed into the openings of the container
carrier at the transverse sides and are glued together with each
other. It is known to fill in ice, in the form of ice cubes for
instance, when buying container carriers which are filled with beer
bottles or beer cans for instance, in order to cool the containers
on the way from the point of sale to the point of consumption. In
this, it is a disadvantage that the ice melts in the
transportation, at least partially, and melt water leaks out of
slits and other openings of the container carrier.
[0003] Departing from this, the present invention is based on the
objective to provide a container carrier made of cardboard which
prevents or at least reduces the leak-out of melt water.
[0004] The objective is resolved by a container carrier with the
features of claim 1. Advantageous embodiments of the container
carrier are indicated in the subclaims.
[0005] The container carrier according to the present invention has
[0006] a bottom wall, [0007] side walls, connected to the
longitudinal sides of the bottom wall via first creasing lines,
[0008] bottom wall flaps, connected to the transverse sides of the
bottom wall via second creasing lines, [0009] side wall flaps,
connected to the transverse sides of the side walls via third
creasing lines, corner connections between the second and third
creasing lines, comprising a layer split-off of at least one
cardboard layer of the bottom wall flaps and/or the side wall
flaps, wherein the layer split-offs are present between first
scribing lines, which are introduced from the outside between
adjacent regions of the side wall flaps and the bottom wall flaps
and which are extended up to the corners between the second
creasing lines and the third creasing lines, and second scribing
lines, which are introduced from the inside into the bottom wall
flaps and which are extended between the second creasing lines and
the sides of the bottom wall flaps neighbouring to the side wall
flaps, and/or third scribing lines, which are introduced from the
inside into the side wall flaps and which are extended between the
third creasing lines and the sides of the side wall flaps
neighbouring to the bottom wall flaps, and [0010] glue tracks,
which are extended departing from the corner connections away from
the second creasing lines and which end in a distance above the
second creasing lines.
[0011] The critical points of a container carrier made of cardboard
through which melt water can leak out are the corners between the
bottom wall, the side walls and the bottom wall flaps and the side
wall flaps of the additional side walls. As the side wall flaps and
the bottom wall flaps are collapsed one upon the other and are
glued together with each other, small openings remain at the
corners, through which melt water leaks out. These openings are
avoided through the corner connections of the container carrier
according to the present invention. As the corner connections are
unhinged from the bottom wall flaps and/or side wall flaps by layer
split-offs, the bottom wall and the side walls are connected to
each other above the corners connections without joining or gluing
spots, respectively. Further, the bottom wall flaps and the side
wall flaps are connected to each other and with the corners
connections via the glue tracks in a liquid-tight manner. As a
consequence, a tightness of the container carrier which corresponds
to the tightness of the cardboard material is also made sure at the
corners.
[0012] In principle, it is sufficient for realising the present
invention to perform the layer split-offs only at the bottom wall
flaps or only at the side wall flaps. When the corner connections
are split off from the bottom wall flap only, they are folded
between them when the bottom wall flaps are collapsed against the
side wall flaps When the corner connections are split off from the
side wall flaps only, they are folded between them when the side
wall flaps are collapsed at the outside against the bottom wall
flaps. Preferably, the corner connections are split off from the
bottom wall flaps and the side wall flaps. This makes it possible
to swivel the bottom wall flaps and the side wall flaps,
respectively, far to the outside, in order to facilitate thrusting
in a group of containers. In order to close the container carrier
at the transverse sides, the bottom wall flaps are swivelled
against the side wall flaps from the outside, a portion of the
corner connections interposing itself or vice versa. Through the
coiner connections and the glue tracks, the container carrier is
sealed at the corners in the vicinity of the bottom wall. The
height of the glue tracks is decisive for the amount of melt water
which can be retained by the container carrier. In principle, the
glue tracks can be realised as narrow strips. A broad or plane-like
realisation of the glue tracks, respectively, i.e. with significant
expansion parallel to the second creasing lines, is also
incorporated Preferably, the extension of the glue tracks away from
the second creasing lines is dimensioned such that the creasing
lines can receive the melt water of an amount of ice which is
typically filled in. As a consequence, openings of the container
carrier situated above them do not lead to any loss of water
[0013] According to one embodiment, the third creasing lines have
cutting lines at a greater distance from the second creasing lines
than the upper end of the glue tracks. As a consequence, the melt
water is retained in the container carrier, provided it does not
rise above the height of the glue tracks. The cutting lines
situated above them facilitate collapsing the side wall flaps when
setting upright the container carrier.
[0014] According to one embodiment, the container carrier has a
handle in its upper region. The handle is formed by grip-in
openings in side walls or by the grip-in opening on an intermediate
wall extended parallel to the side walls, for instance. According
to a further embodiment, the container carrier has a top wall
connecting several side walls with each other at the upside,
wherein a handle is realised completely in the top wall or partly
in the top wall and partly in side walls. According to a further
embodiment, the top wall has top wall flaps articulated on the
transverse sides, wherein top wall flaps, side wall flaps and, as
the case may be, bottom wall flaps are collapsed one upon the other
and connected with each other.
[0015] The handle is formed by grip-in openings in the top wall,
for instance. According to one embodiment, the top wall and
optionally two side walls or the top wall flaps, respectively, have
a pre-punched handle which can be pulled out. For carrying, the
handle is pulled out of the top wall. In doing so, any contact of
the carrying hand with the upper regions of the containers is
avoided.
[0016] According to one embodiment, the container carrier has at
least one opening region in the top wall, delimited by at least one
tear-up line and/or creasing line. After opening the opening region
by tearing up the tear-up line and/or collapsing off the opening
region, the container carrier is opened and ice can be filled in or
containers can be taken out, respectively.
[0017] The present invention is explained in more detail by means
of the attached drawings of an example of its realisation. In the
drawings show:
[0018] FIG. 1 a blank of the container carrier according to the
present invention, flatly spread, in a top view;
[0019] FIG. 2 the same container carrier, partially set upright and
filled with bottles, before closing the side wall and bottom wall
flaps, in an enlarged partial view;
[0020] FIG. 3 the same container carrier with closed side wall flap
and a glue track, in an enlarged side view;
[0021] FIG. 4 the same container carrier opened and with lifted
handle in a perspective side view.
[0022] According to FIG. 1, a blank 1 has a bottom wall 2, on which
side walls 5, 6 are articulated at the long side via first creasing
lines 3, 4.
[0023] Bottom wall flaps 9, 10 are articulated on the transverse
sides of the bottom wall 2 via second creasing lines 7, 8.
[0024] On the transverse sides of the side walls 5, 6 lower side
wall flaps 15, 16, 17, 18 and upper side wall flaps 19, 20, 21, 22
are articulated via third creasing lines 11, 12, 13 14, Outside of
the lower side wall flaps 15, 16, 17, 18 the side walls 5, 6 taper
towards the outside. Correspondingly, the third creasing lines 11
to 14 have a break between the lower side wall flaps 15 to 18 and
the upper side wall flaps 19 to 22.
[0025] Via fourth creasing lines 23, 24, a lower top wall 25 and an
upper top wall 26 are articulated on the outer longitudinal sides
of the side walls 5, 6. The top walls 25, 26 have lower top wall
flaps 31, 32 and upper top wall flaps 33, 34 which are articulated
on their transverse sides via fifth creasing lines 27, 28, 29,
30.
[0026] In the top walls 25, 26 and the top wall flaps 31, 32, 33,
34, lower and upper handles 35, 36 are delimited by punching lines,
The handles 35, 36 have strip-shaped central portions 37, 38 and
fork-shaped end portions 39, 40, 41, 42, which extend departing
from the top wall 25, 26 up to the top wall flaps 31, 32, 33,
34.
[0027] The handles 35, 36 are shaped to be substantially
coincident. Substantially inside the top wall flaps 31, 32, 33, 34,
the end portions 39, 40, 41, 42 have punching lines delimiting
tongues 43, 44, 45, 46 which can be collapsed down between the fork
arms.
[0028] On both sides of the handles 35, 36, there are lower
creasing lines 47, 48 and upper creasing lines 49, 50, which
substantially bridge the distance region between the end portions
39, 40 and 41, 42 of each handle 35, 36.
[0029] In addition, in the upper side wall 26 there are cutting
lines 52, 52 between the handle 36 and the upper creasing lines 49,
50, which also bridge the distance region between the end portions
41, 42.
[0030] The regions of the side walls 25, 26 on both sides of the
handles 35, 36 can be separated off and swivelled towards the side
along tear-up lines 53 to 60, which are arranged on the fifth
creasing lines 27 to 30.
[0031] The bottom wall flaps 9, 10 and the lower side wall flaps
15, 16, 17, 18 are originally connected to each other in the lower
region which is adjacent to the creasing lines 7, 8, 11, 12, 13,
14. By first scribing lines 61, 62, 63, 62 introduced from the
outside (with respect to the ready container carrier), which extend
up to the intersection points of the creasing lines 7 and 11, 7 and
13, 8 and 12, 8 and 14, they are separated from each other in an
outer layer.
[0032] Furthermore, there are second scribing lines 65, 66, 67, 68
in the bottom wall flaps, which departing from the second creasing
lines 7, 8 extend up to the neighbouring outer sides of the
respective bottom wall flaps 9, 10. The second creasing lines 65 to
68 ate introduced into the blank 1 from the inside (with respect to
the ready container carrier). The second creasing lines 65, 66, 67,
68 have two straight portions which hit each other in an obtuse
angle.
[0033] Furthermore, there are third scribing lines 69, 70, 71, 72
in the lower side wall flaps 15, 16, 17, 18, which are also
introduced into the blank 1 from the inside (with respect to the
ready container carrier). The third scribing lines 69 to 72 extend
between the third creasing lines 11, 12, 13, 14 and the sides of
the side wall flaps 15, 16, 17 18, which are facing the bottom wall
flaps 7, 10. Even the third scribing lines 69 to 72 have two
straight portions, which hit each other in an obtuse angle. The
second scribing lines 65 to 68 and the third scribing lines 69 to
72 are arranged symmetrically with respect to the first scribing
lines 61 to 64.
[0034] Before filling with bottles, the upper top wall 26 is
collapsed against the outer side of the lower top wall 25 and glued
together with it. The gluing takes place in the region of the
handles 35, 36 and outside the lower creasing lines 47, 48 and the
upper creasing lines 49 50 for instance, in the shape of a plane, a
line or a point, respectively, for instance.
[0035] In order to fill in bottles, the pre-glued blank 1 is set
upright and a group of bottles 73 is inserted via an opening at the
transverse sides. In doing so, the side wall flaps 15 to 22, the
bottom wall flaps 9, 10 and the top wall flaps 31 to 34 are
swivelled far to the outside. In this, cardboard layers separate
from the bottom wall flaps 9, 10 and the lower side wall flaps 15
to 18, which form corner connections 74, 75, 76, 77. The group of
bottles 73 can be easily inserted into the opening. This situation
is represented in FIG. 2.
[0036] According to FIG. 3, the side wall flaps 15 to 22 are
subsequently collapsed into the openings of the blank at the
transverse sides, and glue tracks 78, 79, 80, 81 are attached on
the lower side wall flaps 15, 16, 17, 18 at the outside, parallel
to the third creasing lines 11, 12, 13, 14, departing from the
corner connections 74, 75, 76, 77. With the glue tracks 78 to 81 it
is dealt with tracks of a hot melt glue. The glue tracks 78 to 81
extend on the corner connections 74 to 77 up to below the second
creasing lines 7, 8 when the bottom wall flaps 9, 10 are collapsed
somewhat below the plane of the bottom wall 6.
[0037] Thereafter, the bottom wall flaps 9, 10 are collapsed upward
and are glued together with the lower side wall flaps 15 to 18
along the glue tracks 78 to 81. Furthermore, the upper side wall
flaps 19 to 22 are also provided with glue tracks and also the
upper edge regions of the bottom wall flaps 9, 10. Thereafter, the
top wall flaps 31 to 34 are collapsed against the upper side wall
flaps 19 to 22 and the upper edge region of the bottom wall flaps
9, 10 and glued together with the same in doing so. Then, the
container carrier is ready.
[0038] According to FIG. 4, the handle 35, 36 is pulled out of the
top wall 25, 26 towards the upside for carrying the container
carrier 82. In this, the fork arms of the end portions 39 to 42
penetrate between the closures of neighbouring bottles 73. The
flaps present adjacent to the strip-shaped portion 37, 38 are
folded below the handle 35, 36 and prevent any cutting-in of the
handle edges into the hand of the carrying person, The legions of
the top wall 25, 26 on both sides of the handle 35, 36 are
separated away along the tearing lines 53 to 60 and are swivelled
to the side around the fourth creasing lines 23, 24. Thereafter,
ice can be filled in from the upside into the container
carrier.
[0039] The corner connections 74 to 77 and the glue tracks 78 to 81
prevent the melt water from dropping out of the corners (in FIG. 4,
the front corner is circled) of the container carrier 82. Undesired
penetration of moist is avoided through this. The user can dispose
the water into a sink as soon as he/she does no more need the
package.
