Description
[0001] The invention relates to a folding box for goods such as
glasses, bottles, jars or similar products, in particular for
cosmetics articles, having a rectangular pack casing, having a lid
part which is connected to the border side of said pack casing and
is provided with an insertion flap which engages in the pack
casing, and having a base offset to the inside of the box.
[0002] EP 0 699 588 A1 discloses a folding pack for goods such as
glasses, bottles, jars or similar products which has a rectangular
pack casing, a lid part which is connected to the border side of
said pack casing and is provided with an insertion flap which
engages in the pack casing, and a base part likewise provided with
an insertion flap.
[0003] Connected to the two walls of the pack casing which are
adjacent to the base part and/or the lid part is in each case one
deformable flap which has three folding lines which run parallel to
the connection border on the pack casing and subdivide the
deformable flap into four individual sections, the outer section
being adhesively bonded to the inside of the pack casing.
[0004] This forms two carriers for accommodating the product which
is to be protected in the pack, and of which the position is
further strengthened by the provision of cutouts in the carriers
which are adapted to the shape of the product.
[0005] In the embodiment selected here, the base of the folding
pack always terminates flush with the surface on which the folding
pack stands. Arranging the base to be offset in the direction of
the interior of the folding pack is not proposed, nor moreover, on
account of the arrangement of the flaps, is it possible.
[0006] The disadvantage with the folding pack is, on the one hand,
that the product located within the pack is not sufficiently
protected and, on the other hand, that the stability of the base is
not increased, precisely as is customary in the packaging
sector.
[0007] EP 0 642 977 A1 discloses a similar box, which has at least
one retaining and protective element for a glass. The box is formed
by four successive main walls. Provided both in the lid region and
in the base region are two conventional closure walls which can
close the box in the known manner.
[0008] Articulated, furthermore, in the lid region are two dust
flaps which, before the top closure wall is inserted into the pack
body, are swung in and thus make it difficult for dirt and dust to
penetrate.
[0009] Essential to the invention are two flaps which are provided
in the base region and are divided up into a multiplicity of
continuous individual sections. Folding said flaps produces within
the box, a double-layered two-part carrier which is made up of the
individual sections and is helpful for fixing the product and for
displaying the same. Provided in the two carrier halves are cutaway
portions, of which the shape and size are adapted to the product
which is to be accommodated.
[0010] The object of the invention is to provide a reclosable
cuboidal folding box which provides a reinforced base, which can be
stacked one upon the other and which provides sufficient protection
to the product located within the folding box, which has a high
level of stability with the smallest possible amount of material
being used, which can be produced cost-effectively using the
smallest possible amount of material, which can be easily and
quickly erected, filled and closed with the aid of machines, and of
which the folding blank is in a single piece.
[0011] This object on which the invention is based is achieved by
the teaching of the main claim. Advantageous configurations are
explained here in the subclaims. The invention also covers a
punched blank of the folding box according to the invention.
[0012] Accordingly, the invention describes a folding box for goods
such as glasses, bottles, jars or similar products, in particular
for cosmetics articles, having a rectangular pack casing, and
having a lid part which is connected to the border side of said
pack casing and is provided with an insertion flap which engages in
the pack casing.
[0013] In each case one intermediate flap is articulated, in the
base region of the folding box according to the invention, on each
of the four side walls which together form the pack casing, the
intermediate flaps all being of the same height. In each case one
base flap is articulated on each of the four intermediate flaps, in
each case two of the base flaps being adhesively bonded to one
another such that the base automatically closes as the folding box
is erected.
[0014] In a first preferred embodiment of the folding box,
connected in an articulated manner, in the lid region, to the two
walls of the pack casing which are adjacent to the lid part is in
each case one flap, said flap having three folding lines which run
parallel to the connection border on the pack casing and subdivide
the flap, as seen from the connection border, into a first spacer
crosspiece, into a supporting strip, into a second spacer
crosspiece and into an adhesive flap. The adhesive flap here is
adhesively bonded to the inside of the pack casing such that the
supporting strip and the second spacer crosspiece are aligned
essentially at right angles to one another.
[0015] The two spacer crosspieces are preferably of the same, or of
at least more or less the same, width.
[0016] The supporting strip and the second spacer crosspiece also
preferably have a cutout which is provided for accommodating the
product and is adapted to the shape of the latter.
[0017] For example, the cutout may be rectangular in the region of
the supporting strip and be circle-arc-shaped or trapezoidal in the
following, second spacer crosspiece.
[0018] Furthermore, the circle-arc-shaped or trapezoidal region of
the cutout may extend as far as the folding line of the adhesive
flap.
[0019] In a further preferred embodiment of the folding box, and in
particular of the flaps, in the case of the flaps, the adhesive
flap is followed in each case by a third spacer crosspiece, via a
folding line, and by a second adhesive flap, via a folding line.
This achieves the situation where the walls of the flaps are at
least partially of double-walled design, which further increases
the stability of the flaps. This is advantageous, in particular, in
the case of heavy products because bowing of the flaps is thus
reliably prevented.
[0020] In the region of the flap, there may be provided a surface
which has an increased coefficient of static and/or sliding
friction and against which the product inserted into the folding
box butts at least partially. In particular, the surface is formed,
in certain regions, by a folding unit which is connected integrally
to the adhesive flap and the supporting strip and has two folding
lines which are spaced apart by a distance corresponding
essentially to the width of the spacer crosspiece.
[0021] In order to improve the stacking capacity of the folding
boxes, it has proven advantageous if at least two side walls of the
folding box which form the pack casing taper slightly in the
direction of the lid region starting from the base region, in which
case the tapering side walls should be arranged opposite one
another.
[0022] The reduction in the side-wall width applies particularly
preferably to all four side walls.
[0023] In this way, the pack casing attains the form of a pyramid
which has a preferably square base surface and of which the vertex
has been removed, a so-called truncated pyramid. The inclination of
the side walls preferably does not exceed 10.degree., but can also
assume much higher values.
[0024] In a further preferred embodiment of the folding box,
provided in a, in particular the front, side wall is a cutout which
extends, in particular, into the adjacent side walls and is
covered, in particular, by a transparent film.
[0025] It is thus easy to see the product located within the pack,
with the result that an aesthetically pleasing product can attract
more potential buyers.
[0026] Furthermore, the film prevents the penetration of dust and,
at the same time, increases the stability, since the action of
punching out the window in the folding box reduces the rigidity of
the folding box. The adhesive bonding of the window film
compensates for the reduction in the rigidity of the folding
box.
[0027] Possible materials for the folding box are all suitable
flexible materials, but in particular cardboard and paperboard.
[0028] The invention also covers at least one punched blank for
producing a reclosable, cuboidal folding box with a front side
wall, a rear side wall, a right-hand side wall, which connects the
front side wall and the rear side wall, and a left-hand side wall,
a base closure, which is formed by four base-closure tabs, and a
top closure, which is formed by three closure tabs, it being the
case that
[0029] the folding box comprises a folding blank made of
paperboard, cardboard or some other suitable material,
[0030] the front side wall, the rear side wall, the right-hand side
wall, which connects the front side wall and the rear side wall,
and the left-hand side wall as well as the flap, each linked to one
another via folding lines, are arranged rectilinearly one behind
the other in a row,
[0031] articulated on the rear side wall, via the folding line, is
a rectangular lid part which terminates, via the folding line, in
an insertion flap which engages in the pack casing, and, on the
opposite side, an intermediate flap via a folding line, a base flap
being articulated on the intermediate flap via the folding
line,
[0032] the right-hand side wall has articulated on it, on the one
hand, a flap via a folding line and, on the other hand, on the
opposite side, an intermediate flap via a folding line, the flap
being divided up into five individual sections, to be precise,
starting from the folding line, into a first spacer crosspiece,
into a crosspiece, into a supporting strip, into a second spacer
crosspiece and into an adhesive flap, between which a total of four
folding lines which are arranged parallel to the pack border are
provided, a base flap being articulated on the intermediate flap
via the folding line,
[0033] an intermediate flap is articulated, via the folding line,
on the front side wall, in which there is provided, if appropriate,
a cutout which extends into the adjacent side walls, a base flap
being articulated on the intermediate flap via the folding
line,
[0034] the left-hand side wall has articulated on it, on the one
hand, a flap via a folding line and, on the other hand, on the
opposite side, an intermediate flap via a folding line, the flap
being divided up into five individual sections, to be precise,
starting from the folding line, into a first spacer crosspiece,
into a crosspiece, into a supporting strip, into a second spacer
crosspiece and into an adhesive flap, between which a total of four
folding lines which are arranged parallel to the pack border are
provided, a base flap being articulated on the intermediate flap
via the folding line.
[0035] The folding box according to the invention has an inwardly
drawn base, in a preferred embodiment flaps in the lid region
which, on the one hand, avoid the penetration of dust into the
folding box and, on the other hand, serve as fixing surfaces
(supports) for the product which is to be stored within the folding
box.
[0036] The fixing surfaces retain the product (in particular a jar
with a screw lid) in a centered manner in the center of the folding
box. These two supports incorporated in the flaps ensure that the
product is fixed well.
[0037] The flaps in the lid region may have additional step-like
recesses which are formed in accordance with the product.
[0038] These additional grips on the two lateral top regions of the
product fix the product in the viewing window of the folding box,
with the printing in a precise position, without subsequent
shifting and turning being possible.
[0039] These additional fixing, adhesively bonded folded sections
in the region of the supports may be adapted to the dimensions of
the product. The inwardly drawn base provides a platform-like
elevation in the interior of the folding box. By virtue of these
two prominent packaging components, the product is retained to good
effect even when subjected to pronounced pressure or vibration. In
conjunction with the cutaway window portion in the front bottom
region of the folding box, the product is displayed in a clearly
visible manner.
[0040] Flaps of straightforward configuration can also support the
product. If alignment, with the printing in a precise position, in
relation to the window of the folding box is to take place,
additional adhesive bonding may be carried out, either on the flaps
or on the base surface.
[0041] This type of adhesive bonding achieves a high crumpling
resistance. The product (in this case a jar) is thus reliably
retained on its tray-like insert. Deformation of the drawn-in base
can be ruled out.
[0042] Particularly advantageous configurations of the folding box
together with the punched blank will be explained in more detail
with reference to the figures described hereinbelow, without there
being any intention of restricting the invention unnecessarily. In
the figures:
[0043] FIG. 1 shows the flattened-out, non-adhesively-bonded
punched blank of an advantageously configured folding box,

box,
[0045] FIG. 3 shows the flattened-out, non-adhesively-bonded
punched blank of a further advantageously configured folding
box,
[0046] FIG. 4 shows the operation of assembling a flap within the
folding box according to FIG. 3,
[0047] FIGS. 5 & 6 show the first steps in the operation of
folding the folding box according to FIG. 2,
[0048] FIG. 7 shows the base closur e of an advantageously
configured folding box, and
[0049] FIG. 8 shows two c o mpleted folding boxes according to the
invention being stacked one upon the other.
[0050] FIG. 1 illustrates the folding blank 10 of the folding box
1, said blank comprising a single-piece cardboard blank. The
folding blank 10 may consist of paperboard, cardboard or some other
suitable material. The body of the erected folding box 1 is formed
by the front side wall 13, the rear side wall 11, the right-hand
side wall 12, which co nne cts the front side wall 13 and the rear
side wall 11, and the left-hand side wall 14, a flap 15 being
articulated laterally on the left-hand side wall 14, and being
adhesively bonded to the rear side wall 11, for the non-releasable
closure of the body.
[0051] All the side walls 11, 12, 13, 14 are rectangular and are
preferably of the same dimensions, with the result that, once
erected, the folding box 1 has a square base surface. The flap 15
tapers slightly trapezoidal in the direction of its free end and is
wide enough for reliable adhesive bonding to the rear side wall 11
to be possible. The flap 15 extends in this case--this being the
maximum space--over the entire length of the side wall 14.
[0052] The individual side walls 11, 12, 13, 14 and the flap 15 are
connected to one another in a row via corresponding folding lines
101, 102, 103, 104.
[0053] In the prominent embodiment of the folding box 1 which is
shown here, provided in the front side wall 13 is a cutout 131
which extends into the adjacent side walls 12, 14 and may be
covered by a transparent film, which is preferably adhesively
bonded correspondingly in the folding-box interior.
[0054] An intermediate flap 21, 22, 23, 24 is articulated, in each
case via a folding line 105, 106, 107, 108, on each of the four
side walls 11, 12, 13, 14 which together forms the pack casing of
the folding box 1, the intermediate flaps 21, 22, 23, 24 all being
of the same height.
[0055] Furthermore, the intermediate flaps 21, 22, 23, 24 are
preferably all of identical shape; they are particularly preferably
rectangular. The height of the intermediate flaps 21, 22, 23, 24
predetermines how far the base 30 of the folding box 1 is
ultimately displaced into the interior of the folding box 1.
[0056] For assembling the folding box 1, the intermediate flaps 21,
22, 23, 24 are swung into the interior of the box 1.
[0057] A base flap 31, 32, 33, 34 is articulated, in each case via
a folding line 112, 113, 114, 115, on each of the four intermediate
flaps 21, 22, 23, 24, in each case two of the base flaps 31, 32,
33, 34 being adhesively bonded to one another such that the base 30
automatically closes as the folding box 1 is erected.
[0058] The base flaps 31, 32, 33, 34 preferably form a base closure
30, as is known according to ECMA Code A 6101 or A 6120 (see "THE
ECMA CODE of FOLDING CARTON STYLES", published by ECMA (European
Carton Makers Association), Reprint January 2000), as a
folding-base closure with a fully covering base flap. Said base
closure 30 is erected automatically, as a result of the specific
shaping of the base flaps 31, 32, 33, 34, as the folding box 1 is
adhesively bonded.
[0059] If the folding box 1 is filled with contents, the base
closure 30 cannot be opened from the outside.
[0060] For assembling the base closure 30, the two adhesive
sections 321, 341, which are integrally formed on the flaps 32 and
34, are adhesively bonded to the flap 33 and 31, to be precise the
section 341 is adhesively bonded to the flap 33 and the section 321
is adhesively bonded to the flap 31.
[0061] As the folding box 1 is erected, the base closure 30 closes
such that the flap 33 becomes a base for the product which is to be
displayed within the folding box. The flap 33 is thus preferably
more or less the same size as the cross section of the folding box
1.
[0062] Articulated on the rear wall 11, at the folding line 109, is
a rectangular lid part 41 which terminates, via the folding line
411, in a insertion flap 45 which engages in the pack casing. The
lid part 41 in conjunction with the insertion flap 45 essentially
form the closure 40 of the folding box 1. The lid part 41 is
therefore preferably of a size which corresponds to the
cross-sectional surface area of the pack casing of the folding box
1, and the insertion flap 45 is rectangular, the free-standing
corners being rounded.
[0063] In each case one deformable flap 42, 44 is connected in an
articulated manner, via the folding lines 110 and 111, to the two
side walls 12 and 14 of the pack casing which are adjacent to the
lid part 41.
[0064] Since the deformable flaps 42 and 44, as is also shown here,
are preferably of identical configurations, the description of the
flaps 42 and 44 will be restricted to the flap 42.
[0065] The deformable flap 42 is divided up essentially into five
individual sections, to be precise, starting from the folding line
110, into a first spacer crosspiece 421, into a crosspiece 422,
into a supporting strip 423, into a second spacer crosspiece 424
and into an adhesive flap 425. A total of four folding lines 120,
121, 122, 123 which are arranged parallel to the pack border are
provided between the five sections comprising the spacer crosspiece
421, crosspiece 422, supporting strip 423, spacer crosspiece 424
and adhesive flap 425.
[0066] The first spacer crosspiece 421, the crosspiece 422, the
supporting strip 423, the second spacer crosspiece 424 and the
adhesive flap 425 are essentially rectangular. For accommodating
the insertion flap 45, however, clearances may be provided on the
corresponding sides of the spacer crosspiece 421, of the crosspiece
422, of the supporting strip 423, of the spacer crosspiece 424 and
of the adhesive flap 425.
[0067] In the exemplary embodiment illustrated, the sum of the
width of the crosspiece 422 and of the second spacer crosspiece 424
is equal to the width of the first spacer crosspiece 421.
[0068] For stabilizing the folding box 1, the first spacer
crosspiece 421 and the crosspiece 422 may be adhesively bonded to
one another.
[0069] The adhesive flap 425 is adhesively bonded to the inside of
the pack casing of the folding box 1 such that the supporting strip
423 and the second spacer crosspiece 424 are aligned essentially at
right angles to one another.
[0070] Together with the supporting strip 443, which is aligned in
parallel once the flap 44 has been folded, this forms a surface
which fixes the contents of the folding box 1 in position, with
result that any movement of the product within the box 1 is ruled
out.
[0071] In the preferred embodiment of the folding box 1 which is
shown here, the two flaps 42 and 44 have cutouts additionally
provided for accommodating the product, to be precise in the
supporting strip 43 and in the second spacer crosspiece 424 and
also in the supporting strip 443 and in the second spacer
crosspiece 444.
[0072] The cutout is rectangular in the region of the supporting
strip 423, whereas it then runs trapezoidally in the spacer
crosspiece 424. The rectilinear part of the cutout in the
supporting strip 424 supports the product, while the trapezoidal
region engages around the product in the lateral region. In this
case, the trapezoidal region of the cutout ends such that, with the
flap 42 folded, a spacing remains between the cutout and the side
wall 12. This makes it possible to engage around a lid of a product
which has a smaller diameter than the container of the product, and
thus to fix the entire product in position.
[0073] The cutout preferably does not extend over the entire
surface area; rather, it is also possible to leave behind, within
the cutout, a rectangular connecting crosspiece 426, which is
connected to the supporting strip 423 via the folding line 424, and
an adhesive extension 427, which is linked to the rectangular
connecting crosspiece 426 via the folding line 125 and to the
adhesive flap 425 via the folding line 123. The adhesive extension
427, which is trapezoidal in particular, the trapezium being
extended as far as the adhesive flap 425 by a rectangle on its
narrow side, is adhesively bonded to the adhesive flap 425. The
connecting crosspiece 426 supports, and also fixes, the product
within the box 1. Overall, the reduced amount of cutting out
increases the overall stability of the folded flap 42.
[0074] FIG. 2 shows a further flattened-out, non-adhesively-bonded
folding blank 10 of an advantageously configured folding box 1,
said folding blank comprising a single-piece cardboard blank.
[0075] The body of the erected folding box 1 is formed by the front
side wall 13, the rear side wall 11, the right-hand side wall 12,
which connects the front side wall 13 and the rear side wall 11,
and the left-hand side wall 14, a flap 15 being articulated
laterally on the left-hand side wall 14, and being adhesively
bonded to the rear side wall 11, for the non-releasable closure of
the body. In order to improve the stacking capacity of the
completed folding box 1, the four side walls 11, 12, 13, 14 taper
slightly in the direction of the lid region 40 starting from the
base region 30, this being illustrated in exaggerated form here for
the sake of clarity.
[0076] The base closure 30 corresponds to that known from the
folding box 1 according to FIG. 1. In each case one base flap 31,
32, 33, 34 is thus articulated on each of the four intermediate
flaps 21, 22, 23, 24, in each case two of the base flaps 31, 32,
33, 34 being adhesively bonded to one another such that the base 30
automatically closes as the folding box 1 is erected, this
producing the base closure 30, as is known according to ECMA Code A
6101 or A 6120 (see "THE ECMA CODE of FOLDING CARTON STYLES",
published by ECMA (European Carton Makers Association), Reprint
January 2000), as a folding-base closure with a fully covering base
flap.
[0077] The cutout 131 is provided in the front side wall 13.
[0078] The essential differences from the folding box according to
FIG. 1 can be found in the lid region 40. Articulated on the rear
wall 11, first of all, is a rectangular lid part 41 which
terminates, via the folding line 411, in an insertion flap 45 which
engages in the pack casing.
[0079] In each case one deformable flap 42, 44 is connected in an
articulated manner, via the folding lines 110 and 111, to the two
side walls 12 and 14 of the pack casing which are adjacent to the
lid part 41.
[0080] The deformable flap 42 is divided up essentially into four
individual sections, to be precise, starting from the folding line
110, into a first spacer crosspiece 421, into a supporting strip
423, into a second spacer crosspiece 424 and into an adhesive flap
425. A total of three folding lines 120, 122, 123 which are
arranged parallel to the pack border are provided between the four
sections comprising the spacer crosspiece 421, supporting strip
423, spacer crosspiece 424 and adhesive flap 425.
[0081] The first spacer crosspiece 421, the supporting strip 423,
the second spacer crosspiece 424 and the adhesive flap 425 are
essentially rectangular.
[0082] The adhesive flap 425 is adhesively bonded to the inside of
the pack casing of the folding box 1, such that the supporting
strip 423 and the second spacer crosspiece 424 are aligned
essentially at right angles to one another.
[0083] The two spacer crosspieces 421 and 424 are preferably of the
same width, but it is also possible for slightly different width to
be selected, as a result of which the supporting strip 423 deviates
slightly from the parallel alignment in relation to the wall of the
pack casing.
[0084] A further special feature is constituted by the so-called
"crowner" 43. Articulated on the side wall 13, via the folding line
401, is a first surface 431, which is followed by a second surface
432 via the folding line 402. A flap 433 is then articulated via
the folding line 403.
[0085] The second surface 432 is preferably of identical dimensions
to the first surface 431, and should not in any way be selected to
be smaller. The two preferably rectangular surfaces 431 and 432 are
adhesively bonded to one another and thus serve as an additional
surface which may provide information on the product contained
therein or an "eye-catcher". The crowner 43 extends vertically from
the folding box 1 in order thus to draw more attention to the box
1.
[0086] The folding line 403 may be configured as a weakened or
predetermined breaking line in order to allow the crowner 43 to be
severed easily from the folding box 1 without damaging the
latter.
[0087] FIG. 3 shows a further flattened-out, non-adhesively-bonded
folding blank 10 of an advantageously configured folding box 1
without a crowner, said folding blank comprising a single-piece
cardboard blank.
[0088] The folding box 1 from FIG. 3 differs from that from FIG. 1
merely by the configuration of the flaps 42 and 44.
[0089] According to FIG. 3, the deformable flap 42 is divided up
essentially into six individual sections, to be precise, starting
from the folding line 110, into a first spacer crosspiece 421, into
a supporting strip 423, into a second spacer crosspiece 424, into
an adhesive flap 425, into a third spacer crosspiece 428 and into a
second adhesive flap 429. A total of five folding lines 120, 122,
123, 126, 127 which are arranged parallel to the pack border are
provided between the six sections.
[0090] In the preferred embodiment of the folding box 1 which is
shown here, the two flaps 42 and 44 have cutouts additionally
provided for accommodating the product, to be precise in the
supporting strip 423 and in the second spacer crosspiece 424 and
also in the supporting strip 443 and in the second spacer
crosspiece 444.
[0091] The cutout is rectangular in the region of the supporting
strip 423, whereas it then runs trapezoidally in the spacer
crosspiece 424.
[0092] The cutout is completed here.
[0093] FIG. 4 discloses the operation of folding up the deformable
flap 42. The operation takes place such that the adhesive flap 425
can be adhesively bonded to the side wall 11, and the second
adhesive flap 429 can also be adhesively bonded to the supporting
strip 423.za
[0094] If the flap 42 is folded over through 90.degree. in relation
to the body of the folding box 1, the supporting strip 423 is
erected parallel to the side wall 11. The double adhesive bonding
considerably increases the fixing support of the product and the
stiffening of the flap 42.
[0095] The cutout is punched out in accordance with the product
contour.
[0096] FIGS. 5 and 6 shows the first steps in the operation of
folding the folding box 1 according to FIG. 2.
[0097] The intermediate flaps 21, 22, 23, 24, which are all of the
same height, are provided with an adhesive and folded over in the
direction of the box 1 such that the intermediate flaps 21, 22, 23,
24 are adhesively bonded to the interior of the side walls, 11,
12,13, 14 (see, in particular, intermediate flap 21 on side wall 11
in FIG. 6).
[0098] The base flaps 31, 32, 33, 34 are folded back through
90.degree. and, for assembling the base closure 30, the two
adhesive sections 321, 341, which are integrally formed on the
flaps 32 and 34, are then provided with an application of adhesive
and are correspondingly adhesively bonded to the flap 33 and
31.
[0099] FIG. 6 indicates the procedure with the flaps 42 and 44 as
well as the crowner 43. The flap 44 is folded, with result that the
supporting strip 443 is arranged parallel to the side surface 14
and the adhesive flap 425 is adhesively bonded to the side surface
14. The flap 42 is also folded accordingly.
[0100] The crowner 43 is produced by the second surface 432 being
folded back through 180.degree., being provided with an application
of adhesive and being pressed onto the first surface 431.
[0101] FIG. 7 shows the base closure 30 of an advantageously
configured folding box 1, to be precise with the base 30 offset to
be inside of the box. The height of the intermediate flaps 21, 22,
23, 24 predetermines the depth to which the base is displaced in
the direction of the box interior.
[0102] FIG. 8, finally, shows how two completed folding boxes 1 and
2 according to the invention are stacked one upon the other.
[0103] As a result of the preferred embodiment of the four side
walls 11, 12, 13, 14 tapering in the direction of the lid region 40
from the base region 30, the cross section of the surface area in
the lid region 40 is smaller than that in the base region 30, and
the top folding box 1--as a result of the base 30 being offset to
the inside of the box--can easily be stacked on the bottom folding
box 2, the two boxes undergoing a relatively fixed connection in
the process.
