Description
[0001] The present invention relates to a cuboid collapsible box
comprising a front wall and a rear wall, comprising a first side
wall and a second side wall, the side walls respectively being
pivotably connected to the front wall and the rear wall to form an
annular main body, comprising a lid closure tab pivotably connected
to the rear wall, comprising a front bottom closure tab, which is
pivotably connected to the front wall, and a rear bottom closure
tab, which is pivotably connected to the rear wall, comprising a
first lateral bottom closure tab, which is pivotably connected to
the first side wall, and a second lateral bottom closure tab, which
is pivotably connected to the second side wall, the bottom closure
tabs forming a bottom closure which runs perpendicular to the first
side wall, to the front wall, to the second side wall and to the
rear wall, the first lateral bottom closure tab being pivotably
connected to the front bottom closure tab and the second lateral
bottom closure tab being pivotably connected to the rear bottom
closure tab, comprising two web surfaces, which form a center web
and are pivotably connected to those edges of two opposing bottom
closure tabs which are facing away from the side walls, and
comprising support surfaces, which extend in the plane of the
bottom closure and the side edges of which bear against the side
edges of the web surfaces. The invention additionally relates to a
collapsible box blank for the manufacture of a collapsible box of
this type.
[0002] Collapsible boxes are used in particular in the
pharmaceutical sector for the packaging of medicines or the like.
Since they contribute to the costs of the product contained in
them, they should comprise little material and be simple to
produce. It is additionally desirable that the collapsible boxes
should be supplied as already pre-glued blanks and that they should
be able to be unfolded, as automatically as possible, only directly
prior to the filling, so as to limit the volume of packaging
material in the transport thereof and, at the same time, minimize
the handling steps in the filling operation.
[0003] From ECMA Code 6020 (see "THE ECMA CODE of FOLDING CARTON
STYLES", published by the ECMA (European Carton Makers Association)
Reprint January 2000), a cuboid collapsible box having a lid
closure and a bottom closure formed out of four bottom closure tabs
is known. In a pre-glued blank of this type, two adjacent bottom
closure tabs are respectively pivotably connected to each other, so
that the bottom closure is oriented perpendicular to the side walls
when the blank is opened out. A drawback with this collapsible box
is, however, that the interior has just a single chamber and is not
divided into part-volumes. It is thus not possible to accommodate
two different products or two batches separate from each other in a
collapsible box of this type.
[0004] A dual-chamber collapsible box is known from ECMA Code
F1013, but it is very material-intensive and awkward to handle. In
particular, when the partly glued blank is unfolded, the bottom
closure is not automatically formed, so that further handling steps
are necessary.
[0005] The present invention is based on a cuboid collapsible box
as is known from DE 102 49 497 A1. The collapsible box which is
disclosed there comprises a front and a rear wall and two side
walls, which are pivotably connected to each other to form an
annular main body. Attached to the top edge of the rear wall is a
lid closure tab, which, together with lateral dust tabs, forms the
lid closure. A front and a rear, and two lateral bottom closure
tabs, form a bottom closure. To the front and rear bottom closure
tabs, a web surface is respectively pivotably connected, in the
unfolded state the web surfaces forming a center web, running
parallel to the front and rear walls, by which the box volume is
divided into two part-volumes. When a partly glued blank of such a
collapsible box is unfolded, both the bottom and the center web
automatically unfold, the front and rear bottom closure tabs
respectively having a support surface, the side edges of which bear
respectively against the side edges of the web surfaces.
[0006] A drawback with a collapsible box of this type is that the
bottom closure and the center web are inadequately secured after
the unfolding, so that, in particular, a pivoting of the center web
is not securely prevented. The center web should be prevented from
pivoting out of the vertical, however, as this would hinder a
reliable automatic filling of the part-chambers of the collapsible
box.
[0007] A further drawback of the collapsible box according to DE
102 49 497 A1 is that the center web runs parallel to the front and
rear walls, whereby the second, rear part-chamber is poorly
accessible for the user.
[0008] Starting from this prior art, the object of the present
invention is to provide a collapsible box, and a blank for the
latter, in which the center web is reliably secured against
pivoting.
[0009] This object is achieved by the fact that the web surfaces
and the support surfaces are connected to the lateral bottom
closure tabs, that on the lateral bottom closure tabs, at the ends
facing away from the side walls, retaining surfaces are provided,
that the front and rear bottom closure tabs have latching surfaces,
and that the latching surfaces bear from below against the
retaining surfaces and from above against the lateral bottom
closure tabs.
[0010] The latching surfaces bearing from below against the
retaining surfaces and from above against the lateral bottom
closure tabs have the effect, together with the retaining surfaces,
that the bottom closure as a whole is pretensioned in the upward
direction. Since a movement of the support surfaces in the
direction of the side edge of the opposite web surface is linked to
an upward movement of the bottom closure, the pretensioning leads
to a firmer engagement of the side edges of the support surfaces
with the side edges of the web surfaces. The web surfaces are thus
reliably secured against pivoting by the support surfaces.
Moreover, the latching surfaces rest on the respectively opposite
front and rear bottom closure tabs and thereby increase the
stability of the bottom.
[0011] A further advantage of the collapsible box according to the
invention lies in the fact that the center web runs perpendicular
to the front and rear walls. The products are hence, with the front
sides, visible to the user and are immediately removable in a
user-friendly manner. At the same time, the possibility exists of
placing different ranges of goods in the compartments.
[0012] Preferably, a recess which opens toward the front bottom
closure tab is provided between the first lateral bottom closure
tab and the retaining surface, and a recess which opens toward the
rear bottom closure tab is provided between the second lateral
bottom closure tab and the retaining surface. When the latching
surfaces, as the blank is unfolded, are slid into the recesses, the
latching surfaces and the lateral bottom closure tabs are
effectively prevented by the rigidity of the box material from
lying in one plane, thereby producing a sufficiently strong,
upwardly directed pretensioning of the bottom closure.
[0013] Furthermore, it is preferred that that edge of the latching
surface provided on the front bottom closure tab which is facing
away from the first side wall and that edge of the latching surface
provided on the rear bottom closure tab which is facing away from
the second side wall are beveled. The effect of this is that, as
the blank is unfolded, the respectively opposite front or rear
bottom closure tab is forced under the latching surface and the
bottom closure is automatically formed in the desired manner.
[0014] It is further preferred that the web surfaces bear one
against the other in an overlap region. Since the web surfaces are
connected by a fold to the lateral bottom closure tabs, they tend
in principle to pivot back out of the secured state into the plane
of the bottom closure. If the web surfaces bear one against the
other, they are mutually supporting, so that a vertical position of
the center web is additionally assured.
[0015] In a further preferred embodiment, the web surfaces have
rounded edges in order that, as the blank is unfolded, the web
surfaces running initially in one plane with the lateral bottom
closure tab do not become wedged.
[0016] Furthermore, the support surfaces can have rounded edges, so
that, as the blank is unfolded, these can push against the side
edges of the web surfaces without having to be strongly pivoted out
of the plane of the lateral bottom closure tabs. Additionally, this
facilitates the automatic unfolding.
[0017] Preferably, the support surfaces are formed by punch-outs in
the web surfaces, whereby a web surface extending, as far as
possible, over the entire width of the lateral bottom closure tab
can be realized in a simple manner.
[0018] For a high stability of the bottom closure, it is
additionally preferred that the first and second lateral bottom
closure tabs respectively have pivotable connecting tabs, which are
glued to the front and rear bottom closure tabs respectively.
[0019] In order that, in the unfolding operation, the bottom
closure straightens up without becoming wedged, it is additionally
preferred that that edge of the front bottom closure tab which is
facing toward the first lateral bottom closure tab forms an angle
of 45.degree. with the bottom edge of the front wall, and that that
edge of the rear bottom closure tab which is facing toward the
second lateral bottom closure tab forms an angle of 45.degree. with
the bottom edge of the rear wall.
[0020] The above object is achieved, moreover, by a collapsible box
blank as claimed in claim 10, preferred embodiments being described
in the following subclaims. With regard to the advantages
associated herewith, reference is made to that which has already
been stated with respect to the collapsible box.
[0021] The present invention is described below with reference to a
drawing representing merely one preferred illustrative embodiment.
In the drawing,
[0022] FIG. 1 shows a blank according to the invention of a cuboid
collapsible box,
[0023] FIG. 2 shows a collapsible box according to the invention in
perspective representation,
[0024] FIG. 3 shows the bottom closure tabs of a collapsible box
according to the invention separated from one another in
perspective representation,
[0025] FIG. 4 shows the bottom closure tabs of a collapsible box
according to the invention in partially connected and unfolded
setting, and
[0026] FIG. 5 shows the bottom closure tabs of a collapsible box
according to the invention in connected and unfolded setting, the
web surfaces not being represented.
[0027] FIG. 1 represents a collapsible box blank according to the
invention for a cuboid collapsible box shown in FIG. 2. The blank
comprises a first side wall 1, a front wall 2, a second side wall 3
and a rear wall 4. The walls are respectively pivotably connected
along their side edges to the adjacent walls. A tab 5 is pivotably
connected to that side edge of the first side wall 1 which lies
opposite the front wall 2.
[0028] To the respective bottom edges 6, 7, 8 and 9 of the first
side wall 1, the front wall 2, the second side wall 3 and the rear
wall 4 there are pivotably connected a first lateral bottom closure
tab 10, a front bottom closure tab 11, a second lateral bottom
closure tab 12 and a rear bottom closure tab 13.
[0029] The lateral bottom closure tabs 10, 12 have pivotable
connecting tabs 14, 15, via which the first lateral bottom closure
tab 10 can be glued to the front bottom closure tab 11, and the
second lateral bottom closure tab 12 to the rear bottom closure tab
13. In this, in this regard, preferred illustrative embodiment,
those edges 16, 17 of the front and rear bottom closure tabs 11, 13
which are facing toward the connecting tabs 14, 15 respectively
form an angle .alpha. of 45.degree. with the bottom edges 7, 9 of
the front wall 2 and rear wall 4.
[0030] On the lateral bottom closure tabs 10, 12 there are provided
retaining surfaces 18, 19, which are disposed at the ends facing
away from the side walls 1, 3 and run in the plane of the lateral
bottom closure surfaces 10, 12. The retaining surfaces 18, 19 are
shown in shaded representation, purely for the sake of clarity.
Apart from that, they are rigidly connected to the lateral bottom
closure tabs 10, 12.
[0031] On those edges of the lateral bottom closure tabs 10, 12
which are facing away from the side walls 1, 2 there are provided
pivotable web surfaces 20, 21. Likewise on those edges of the
lateral bottom closure tabs 10, 12 which are facing away from the
side walls 1, 2 there are disposed support surfaces 22, 23, which
are rigidly connected, however, to the bottom closure tabs 10, 12.
In the, in this regard, preferred illustrative embodiment, the web
surfaces 20, 21 and the support surfaces 22, 23 have rounded edges.
Furthermore, the support surfaces 22, 23 are formed by punch-outs
in the web surfaces 20, 21.
[0032] Between the connecting tab 14 and thus the first lateral
bottom closure tab 10 and the retaining surface 18, a recess 24 is
provided which opens in the direction of the front bottom closure
tab 11. In the same way, between the connecting tab 15 and thus the
second lateral bottom closure tab 12 and the retaining surface 19,
a recess 25 is provided, which opens in the direction of the rear
bottom closure tab 13. In the present case, the recesses 24, 25 are
configured as slits between the retaining surfaces 18, 19 and the
connecting tabs 14, 15.
[0033] On the edge lying opposite the front wall 2, the front
bottom closure tab 11 has a front latching surface 26. In the same
way, on that edge of the rear bottom closure tab 13 which lies
opposite the rear wall 4, a rear latching surface 27 is provided.
Here, the latching surfaces 26, 27 are respectively rigidly
connected to the bottom closure tabs 11, 13.
[0034] In the, in this regard, preferred illustrative embodiment,
that edge 28 of the front latching surface 26 which is facing away
from the first lateral bottom closure tab 10 is beveled. In
precisely the same way, that edge 29 of the rear latching surface
27 which is facing away from the second lateral bottom closure tab
11 is beveled.
[0035] A lid closure tab 30 is pivotably connected to the top edge
of the rear wall 4. Furthermore, on the top edges of the side walls
1, 3, pivotable dust tabs 31, 32 are provided.
[0036] In a collapsible box according to the invention produced
from the previously described blank, the tab 5 is glued to the rear
wall 4, so that the latter is pivotably connected to the first side
wall 1. As a result, the walls 1, 2, 3 and 4 form a
parallelogram-like, annular main body. Furthermore, the first
lateral bottom closure tab 10 and the front bottom closure tab 11
are pivotably connected to each other by the connecting tab 14, the
pivot axis running along the edge 16, which is angled at
45.degree.. Analogously, the second lateral bottom closure tab 12
and the rear bottom closure tab 13 are connected.
[0037] If the parallelogram-like main body is folded flat, the
bottom closure tabs 10, 11, 12 and 13 fold upward with the web
surfaces 20, 21 and come to bear against the walls 1, 2, 3 and 4.
In turn, in the opening-out operation, the bottom closure tabs 10,
11, 12 and 13 are pivoted downward. The web surfaces 20, 21
hereupon enter initially with their beveled edges into bearing
contact with each other and are pivoted upward relative to the
lateral bottom closure tabs 10, 12. If the walls 1, 2, 3 and 4 form
a rectangle in the opened-out state, the bottom closure tabs 10,
11, 12 and 13 run in a plane perpendicular to the walls 1, 2, 3 and
4. The web surfaces 20, 21 run, in turn, perpendicular to the
bottom closure tabs and form a center web, so that the box is
divided into two part-volumes, the center web running perpendicular
to the front and rear walls 2, 4. Furthermore, in an overlap region
35, the web surfaces 20, 21 bear one against the other and are thus
mutually supporting.
[0038] As can be seen from FIG. 2, in the opened-out state the side
edges 33, 34 of the web surfaces 20, 21 come into bearing contact
with the edges of the support surface 22, 23. Provided that the
bottom closure tabs 10, 11, 12 and 13 are pretensioned such that
they pivot upward, the edges 33, 34 of the web surfaces 20, 21 are
pressed against the edges of the support surfaces 22, 23. As a
result, the web surfaces 20, 21 are secured in their perpendicular
setting and the center web thus remains in the desired setting.
[0039] While FIG. 3 shows the bottom closure tabs 10, 11, 12 and 13
fully separated from one another, in FIG. 4 their setting relative
to one another in the opened-out state of the collapsible box is
represented. FIG. 5 shows the bottom closure formed by the bottom
closure tabs 10, 11, 12 and 13, the web surfaces 20, 21 having been
omitted for the sake of clarity. It can be seen from FIG. 5, in
particular, that the front latching surface 26 bears from below
against the retaining surface 18 and from above against the first
lateral bottom closure tab 10. In the same way, the rear latching
surface 27 bears from below against the retaining surface 19 and
from above against the second lateral bottom closure tab 12. Here,
the latching surfaces 26, 27 are respectively inserted in the
recesses 24, 25 formed in the lateral bottom closure tabs 10,
12.
[0040] The inserted latching surfaces 26, 27 produce an upward
pretensioning of the bottom closure tabs 10, 11, 12 and 13. As
already described, this pretensioning in turn brings about the
securement of the web surfaces 20, 21 by means of the support
surfaces 22, 23. Furthermore, the latching surfaces 26, 27 lead to
an increased stability of the bottom closure, since they
additionally prevent possible downward pivoting of the bottom
closure tabs 10, 11, 12 and 13.
[0041] Since, in the, in this regard, preferred illustrative
embodiment, the edges 28, 29 of the latching surfaces 26, 27 are
beveled, the latching surfaces 26, 27, in the opening-out
operation, cannot become wedged with the respectively opposite
front or rear bottom closure tab 11, 13. The effect of this,
moreover, is that, as the blank is unfolded, the respectively
opposite front or rear bottom closure tab 11, 13 is forced under
the respective latching surface 26, 27 and the bottom closure is
automatically formed in the desired manner.
[0042] It can additionally be seen from FIG. 5 that the first
support surface 22 rests partly on the retaining surface 19 of the
second lateral bottom closure tab 12 and partly on the rear bottom
closure tab 13. In the same way, the second support surface 23
rests on the retaining surface 18 of the first lateral bottom
closure tab 10 and on the front bottom closure tab 11.
[0043] The collapsible box according to the invention thus has a
firmly secured center web, which is disposed, moreover,
perpendicular to the front and rear walls 2, 4. Products contained
in the collapsible box are hence, with the front side, visible to
the user.
