Description
[0001] The invention relates to an inlay for a secondary packaging
with a rectangular base area for holding edge-stable, rectangular
products.
[0002] DE 299 10 815 U1 discloses unipartite blanks which can also
be made of corrugated cardboard and used for encapsulating
products, i.e. for producing what are known as dividers. What is
involved here is cushioning products, such as bottles, on all sides
and packaging them in a shockproof manner. For this purpose, the
blank is provided with adhesive tabs and adhesive-bonding
faces.
[0003] JP 2008-081147 A discloses a unipartite blank which, when
correspondingly folded, is intended to serve for holding products.
The position of the products is predetermined by punched-out
portions in the blank. The number of punched-out portions gives the
maximum number of products held.
[0004] It is intended to develop a transport-stable secondary
packaging for a plurality of products packaged in primary
packaging, in particular for products from the pharmaceutical
sector. Here, it is assumed that a secondary packaging with a
rectangular base area, for example a standard folding-box
structure, is the secondary packaging and edge-stable, rectangular
products are the products packaged in primary packaging. In order
to secure the products packaged in primary packaging in a stable
manner against slipping and possible resultant damage, an inlay is
required. The inlay is intended to be suitable for the purpose of
holding and protecting the products packaged in primary packaging
and furthermore to be removal-friendly and easily produced and to
adapt flexibly to slight variations in the size and quantity of the
secondary packaging.
[0005] An essential constituent part of the inlay is a rectangular
blank which consists of a material with a corrugation profile. The
blank has a width B parallel to the corrugation profile and a
length L at a right angle to the corrugation profile, that is to
say substantially along a constant position in the corrugation
profile. The blank has at least four fold marks, which are parallel
to the corrugation profile. In order to mount the inlay, the blank
is bent at the fold marks such that the face between the two inner
fold marks forms a base and the respectively adjoining faces form
side faces which are arranged substantially perpendicular to the
base, with the result that a U-shaped structure is produced. The
faces which are arranged on the outside at the outer fold marks of
the blank, the clamping faces, are either both bent over in the
direction of the interior of the U-shaped structure or both bent
over in the direction of the exterior of the U-shaped structure.
The angle between the clamping faces and side faces of the U-shaped
structure, whether it is inwards or outwards, varies in the range
of from 5 degrees to 90 degrees. The blank which is folded or bent
at the fold marks in this way forms the inlay.
[0006] The outer faces which are bent down outwardly at an angle in
the range of from 5 degrees to 90 degrees, preferably 5 degrees to
70 degrees, particularly preferably 5 degrees to 30 degrees, with
respect to the respective side wall serve as clamping devices
which, when the inlay is being inserted in the secondary packaging,
serve to resiliently support the substantially perpendicular side
walls of the inlay against the wall of the secondary packaging. An
edge-stable, rectangular product which is inserted perpendicular to
the corrugation profile in the inlay and has a width which
corresponds substantially to the width of the base and/or the
spacing between the side walls of the inlay brings about a
counterforce with respect to the clamping device, with the result
that the side walls of the inlay are stabilized on both sides in
the secondary packaging.
[0007] As an alternative, the outer faces are bent down inwardly at
an angle in the range of from 5 degrees to 90 degrees, preferably 5
degrees to 45 degrees, particularly preferably 5 degrees to 15
degrees, with respect to the respective side wall. They serve as
clamping devices which, when the inlay is being inserted in the
secondary packaging, in combination with the edge-stable,
rectangular product press the substantially perpendicular side
walls of the inlay resiliently against the wall of the secondary
packaging. For this purpose, it is necessary that an edge-stable,
rectangular product which has a width corresponding substantially
to the width of the base and/or the spacing between the side walls
of the inlay is inserted perpendicular to the corrugation profile
in the inlay. The inwardly bent-down outer faces are supported
resiliently against the product and press the side walls outwards
against the wall of the secondary packaging. This can have the
effect that the side walls of the inlay are no longer oriented
precisely perpendicular to the base, but rather the angle between
the base and the side wall is enlarged by a few degrees beyond 90
degrees, e.g. to up to 95 degrees. In this embodiment, the
edge-stable, rectangular products are mounted in a particularly
stable manner in the inlay when, in addition to the corrugation
profile present, the edge at the ends of the blank that come into
contact with the edge-stable, rectangular products is also
corrugated and has a similar, preferably the same, corrugation
length as the corrugation profile of the blank. Thus, the
edge-stable, rectangular products are also fixed on the third side
in a certain position, predefined by a corrugation trough. As an
alternative, the edge at the end of the blank can also contain
slots, preferably at a spacing which corresponds to the spacing
between the corrugation troughs in the corrugation profile. The
edge-stable, rectangular product can engage into the slots and thus
additionally be fixed in a predefined position.
[0008] The spacing of the two outer fold marks from the edge of the
blank is smaller than the spacing between the fold marks between
which the side walls are formed, and therefore the clamping devices
can be inserted in an effective and space-saving manner.
[0009] In an alternative embodiment, the two outer fold marks of
the blank do not extend over the entire width B of the blank, but
rather only over a central partial region of the width B of the
blank. In addition, the blank has cuts or perforations in the
longitudinal direction of the blank between the ends of the outer
fold marks and the respectively closest fold marks. In this
embodiment, the side walls of the inlay after bending/folding are
formed between the first or second end of the blank and the second
fold mark numbered from the respective end of the blank. The faces
for the clamping devices are disposed in the manner of a window in
the side walls and can be folded out towards the interior or
exterior of the U-shaped structure. The function of stabilizing the
side wall of the inlay between the edge-stable, rectangular product
and the wall of the secondary packaging is the same as in the
embodiments described above.
[0010] One or more edge-stable, rectangular products can be
inserted in the U-shaped region of the inlay between the base and
the side walls. Advantageously, an inlay has a plurality of
U-shaped regions that lie next to one another for receiving one or
more edge-stable, rectangular products. For this purpose, the blank
from which the inlay is folded has, for example, seven fold marks
for two U-shaped regions that lie next to one another or ten fold
marks for three U-shaped regions that lie next to one another. By
means of in each case three further fold marks with corresponding
spacings from one another and the existing fold marks in the blank,
the inlay can in each case be enlarged around a U-shaped
region.
[0011] From seven fold marks and/or two U-shaped regions that lie
next to one another, using the fourth (sixth, tenth . . . ) fold
marks from one end of the blank, a centre wall is formed by bending
being performed at these fold marks of the blank by 180 degrees.
The faces which lie against these folding edges/bending edges thus
come to lie parallel to one another, and the result is a
double-layer centre wall. The height of this centre wall depends on
the spacing between the two fold marks which lie closest to the
fourth (seventh, tenth . . . ) fold marks. This spacing should be
in the range of from 50% to 100% of the spacing of the respectively
two outermost fold marks between which the side walls are
formed.
[0012] The fold marks are produced by scoring, grooving or
perforation of the blank. At the fold marks, the blank is folded
(mechanically) or bent (manually) so that bent edges form and the
blank regions which adjoin the fold marks are at a new, predefined
angle with respect to one another.
[0013] Plastic with a corrugation profile or paper or corrugated
cardboard comes into consideration as a material for the blank from
which the inlay is bent or folded. The corrugation profile is
important because it makes it possible to hold the edge-stable,
rectangular products perpendicularly in the inlay. For this
purpose, the individual edge-stable, rectangular products are
positioned in the U-shaped regions such that with their edges they
come into contact with a corrugation trough of the corrugation
profile on three sides. The minimum spacing between the
edge-stable, rectangular products is thus predefined by the
configuration of the corrugation profile.
[0014] In order to keep the edge-stable, rectangular products
stable even during transport and when being individually removed,
the inlay has the clamping devices described above. The restoring
forces at the outside bending edges and the material strength
result in the tension required to keep the edge-stable, rectangular
products in the desired position.
[0015] Polystyrene, foam or air-bubble sheet, for example, can be
used as a plastic with a corrugation profile.
[0016] An open corrugated cardboard having a material strength in
the range of from 40 g/m.sup.2 to 200 g/m.sup.2, preferably in the
range of from 60 g/m.sup.2 to 150 g/m.sup.2, particularly
preferably in the range of from 80 g/m.sup.2 to 120 g/m.sup.2, and
having a corrugation size or corrugation type in the range of from
F-flute to C-flute in accordance with DIN 55468-1:2015-06, can be
used as corrugated cardboard.
[0017] A padded paper with air pockets can be used as paper with a
corrugation profile.
[0018] The inlay is suitable for use in a secondary packaging
having a rectangular base area which in a first dimension is not
less than the width of the blank B. With respect to the second
dimension of the base area, the inlay and secondary packaging
should be matched to one another such that the size of the base
area of the secondary packaging in the second dimension is greater
than the length which results from the sum of the longitudinal
extent of the base areas of the inlay, and less than the length
which results from the sum of the longitudinal extent of the base
areas of the inlay plus the longitudinal extent of the outer faces
forming the clamping device. Only in this way can it be ensured
that the inlay with the edge-stable, rectangular products is
mounted stably in the secondary packaging.
[0019] Edge-stable, rectangular products are, for example, sachets,
blister packs, four-edge sealed pouches or tubular pouches.
[0020] The secondary packaging having a rectangular base area can
be a box of wood, plastic, metal or cardboard, and in particular a
folding box.
[0021] The inlay according to the invention makes it possible to
stably position edge-stable, rectangular products in a secondary
packaging having a rectangular base area. It is removal-friendly,
easy to produce and, within certain limits, can be adapted flexibly
to the size of the secondary packaging.

[0053] FIG. 1 shows a rectangular blank 10 for an inlay 20 with 2
U-shaped regions. The blank 10 has a width B parallel to the
corrugation profile 22 and a length L at a right angle to the
corrugation profile, i.e. along a constant position in the
corrugation profile. The length L extends along a first axis x from
the first end 11 of the blank 10 to the second end 12 of the blank
10. The width B extends along a second axis y which is
perpendicular to the first axis x. The embodiment, shown in FIG. 1,
of the blank 10 has seven fold marks 14a, 14b, 14c, 14d which are
parallel to the second axis y. The spacing of the two outer fold
marks 14a from the first and second end (11, 12) of the blank 10 is
smaller than the spacing between the fold marks 14c and 14a.
[0054] In order to mount the inlay 20, the blank 10 is bent at the
fold marks 14c and 14d by 90 degrees such that the faces between
the two inner fold marks 14c and 14d form a base 15 in each case
and the respectively adjoining faces form side walls 16 and/or
centre walls 18 which are arranged substantially perpendicular to
the base 15 (see FIGS. 2-4), with the result that two U-shaped
structures that lie next to one another are produced. The faces
which are arranged on the outside at the outer fold marks 14a of
the blank 10, the clamping faces 17, are either both bent over in
the direction of the interior of the U-shaped structure (FIG. 3) or
both bent over in the direction of the exterior of the U-shaped
structure (FIG. 2).
[0055] The angle .alpha. between the clamping faces 17 and side
walls 16 of the U-shaped structure, in the case of the clamping
faces 17 which are bent over in the direction of the exterior of
the U-shaped structure, in FIG. 2 is approximately 60 degrees.
[0056] The angle .beta. between the clamping faces 17 and side
walls 16 of the U-shaped structure, in the case of the clamping
faces 17 which are bent over in the direction of the interior of
the U-shaped structure, in FIG. 3 is approximately 35 degrees.
[0057] In the case of the inwardly bent-over clamping faces 17 in
FIG. 3, in the perspective view, the corrugated edge at the outer
end 11, 12 of the clamping face 17 can be clearly seen. The
corrugated edge can additionally fix an edge-stable, rectangular
product 40.
[0058] In the alternative embodiment, shown in FIG. 4, of the inlay
20, the two outer fold marks 14a of the blank do not extend over
the entire width B of the blank 10, but rather only over a central
partial region of the width B of the blank 10. In addition, the
blank 10 has cuts or perforations in the longitudinal direction of
the blank 10 between the ends of the outer fold marks 14a and the
respectively closest fold mark 14c. In this embodiment, the side
walls 16 of the inlay 20 after bending/folding have been formed
between the first or second end 11, 12 of the blank 10 and the
second fold mark 14c numbered from the respective end 11, 12 of the
blank 10. The faces for the clamping devices 17 are disposed in the
manner of a window in the side walls 16 and can be folded out
towards the exterior of the U-shaped structure.
[0059] FIG. 5, in a front view, and FIG. 6, in a perspective view,
show an inlay 20 with 2 U-shaped regions which are located in a
secondary packaging 30. In each U-shaped region, an edge-stable,
rectangular product 40 has been inserted. The edge-stable,
rectangular product 40 has been inserted in the inlay 20
perpendicular to the corrugation profile 13 into a corrugation
trough of the blank 10. The edge-stable, rectangular product 40 has
a width which corresponds substantially to the width of the base 15
and/or the spacing between the side wall 16 and the centre wall 18
of the inlay 20. The edge-stable, rectangular product 40 brings
about a counterforce with respect to the outwardly bent clamping
devices 17, with the result that the side walls 16 of the inlay 20
are stabilized in the secondary packaging 30 from both sides. The
two centre walls 18 are also held in position by the edge-stable,
rectangular product 40. Since the length of the secondary packaging
30 is only a little greater than the length of the two bases 15,
the pressure between the walls of the secondary packaging 30 and
the clamping devices 17 is strong enough that the clamping devices
17 form a very small angle with the side walls of the inlay 20. The
pressure between the walls of the secondary packaging 30 and the
clamping devices 17 makes it more difficult for the inlay 20 to
slip in the secondary packaging 30.
[0060] At the top edge of the centre wall 18, which has been formed
at the fold mark 14b, the corrugation profile 13 extending over the
width of the blank can be clearly seen.
[0061] FIG. 7, in a front view, and FIG. 8, in a perspective view,
show an inlay 20 with 2 U-shaped regions that is located in a
secondary packaging 30. In each U-shaped region, as in the example
in FIGS. 5 and 6, an edge-stable, rectangular product 40 has been
inserted. The clamping devices 17, bent down inwardly here, are
supported resiliently against the edge-stable, rectangular product
40 and press the side walls 16 outwards against the wall of the
secondary packaging 30. As a result, the side walls 16 of the inlay
20 are no longer oriented precisely perpendicular to the base 16,
but rather are tilted by a few degrees outwardly against the wall
of the secondary packaging 30. A slipping of the inlay 20 in the
secondary packaging 30 is made more difficult by the friction
between the inlay 20 and the secondary packaging 30.
[0062] For the inlays in FIGS. 5 to 8, a corrugated cardboard
having a material strength of 90 g/m.sup.2 and an E-flute is used.
For the inlays according to the invention, corrugated cardboards
having corrugation sizes in the range of C-flutes, D-flutes,
E-flutes or F-flutes are particularly suitable. The dimensions of
these corrugation sizes are defined in DIN 55468-1:2015-06. The
corresponding overview is shown in FIG. 9.
