Description
[0001] The invention relates to a powder-tight packaging for a
product, in particular for a pulverulent product, preferably a
washing or cleaning powder, which packaging is formed from a
folding blank which comprises at least one rear face, one front
face and two end faces of the packaging that are attached to one
another and delimited by folding lines, which, in order to
construct the packaging, is closed to form a tubular shape and
which comprises at least one lid flap and at least one base flap
for closing the base and the lid and for forming the base surface
and the lid surface of the packaging, which surfaces respectively
adjoin lower and upper edges of the front face, the rear face
and/or the end faces via folding lines.
[0002] The invention also relates to a folding blank for the
abovementioned packaging.
[0003] Packagings of this type have been commercially available for
decades in a cuboidal form, in particular for detergent powders.
Packagings of this type are also used for pourable food products,
such as breadcrumbs, cornflakes or the like.
[0004] A packaging of this type is to be distinguished particularly
from packagings which are formed from a so-called "wrap-around
blank" which is used particularly for bulky products, for example
for detergent tablets. In this case, the tablets to be packed are
stacked, for example, on a base region of a folding blank and the
blank is then folded up and wrapped around the product in order to
close the packaging and to surround the bulky item, and the
packaging is closed. A packaging of this type does not particularly
have to be powder-tight.
[0005] In contrast, in the packaging of the generic type, a
packaging space is first formed which remains open on only one side
and then is filled with the
[0006] pourable product, after which the last side, and therefore
the entire packaging, is closed. To this end, a tubular shape may
initially be formed from the blank and the base may then be closed.
Filling would then be carried out and finally the lid would be
closed. In principle, however, it is also possible to lastly close,
for example, one end face after the filling operation.
[0007] The invention is based on the object of improving handling
of a packaging of the generic type mentioned in the
introduction.
[0008] According to the invention, this object is achieved in that
the base surface and the lid surface of the packaging are each of
quadrilateral, in particular rectangular, design and the folding
blank comprises additional side regions which are arranged in such
a way that, in the closed tubular shape, one of the additional side
regions in each case extends between the rear face and each end
face and between the front face and each end face, so that the
closed tubular shape has a cross section with more than four
corners, preferably eight corners, in its middle region, and in
that each of the additional regions tapers to form a point at its
lower and upper ends, with the lower point being involved in the
formation of one of the corners of the base surface and the upper
point being involved in the formation of one of the corners of the
lid surface.
[0009] As a result, the packaging according to the invention is
advantageously given a shape in which the lid and the base remain
rectangular but the body of the packaging has eight surfaces. In
contrast to a cuboidal shape, this preferably leads to it being
possible for the end surfaces to be narrower. This in turn
advantageously makes it easier to pick up the packaging according
to the invention because packagings of this type, in particular for
detergent or cleaning powder, are of a size which can be picked up
from the shelf from the side. However, this is easier with the
packaging according to the invention because, on account of its
angled design, the end-face region, which now comprises an end face
and two adjoining additional side regions, better matches the
rounded shape of the hand which is picking it up, is narrower in
the end-face region and, in particular, is more convenient to pick
up because the edges are less palpable. This is particularly
advantageous for women since their hands are, on average, somewhat
smaller than men's hands.
[0010] Secondly, the packaging may remain rectangular in the lid
region and in the base region as is customary, so that said
packaging can be opened and closed in the customary manner and, in
particular, the packaging according to the invention can be
produced, constructed and filled largely using conventional
machines.
[0011] However, the packaging according to the invention is also
easier to handle in a further regard. Since said packaging has
eight edges and surfaces, the packaging according to the invention
can be stacked, in particular palletized, in a much more stable
manner, with the size of the required standing area not being
increased. If an octagonal shape, whose edge regions are smaller
than those of a rectangular shape, is required to retain the same
volume, it is accordingly necessary to provide a greater volume
height. However, in reality, packagings of this type, in particular
for reasons of filling technology, are never filled right up to the
lid, with the result that it is readily possible to vary the
filling level within the packaging without having to change the
height of the packaging itself, that is to say its external
dimensions. In this regard, it is advantageously not necessary to
makes any changes in terms of storage of the packaging according to
the invention either. In Germany, the filling level shall be
provided in accordance with DIN 55540.
[0012] One preferred embodiment of the packaging according to the
invention provides for the additional side regions to be narrowed
in relation to the width of the end faces so as to form beveled
surfaces. This therefore means that, in relation to a cuboidal
shape, essentially actually only the edges are broken, that is to
say one vertical edge is in each case replaced by two edges which
are not very widely spaced apart from one another. This
particularly improves handleability and stackability of the
packaging according to the invention. The additional side regions
are preferably at angles of up to 135.degree. in relation to their
adjacent end faces and the rear face and the front face in the
closed tubular shape. Their corner regions and edge regions
therefore form a relatively large obtuse angle with these adjacent
faces. In contrast to the cuboidal shape of a conventional
packaging and in contrast to the rectangular shape of the lid
surface and the base surface, the additional side surfaces cut the
vertical edges, that is to say diagonally by an angle of
approximately 45.degree..
[0013] The folding blank is preferably adhesively bonded in a joint
region in order to form the tubular shape. To this end, an adhesive
flap may preferably be provided, which adhesive flap is arranged
particularly at an edge of the front face or rear face which is
free of an additional side region by means of a folding line. The
packaging according to the invention is then, that is to say before
it is filled, adhesively bonded at the side joints, preferably by
an adhesive flap and an additional side region partially
overlapping for adhesive bonding purposes. However, it is of course
possible to provide other adhesive-bonding means, in particular in
the region of the rear face. Adhesive bonding should, however,
preferably be performed such that the joint interferes with
handling of the packaging to the least possible extent.
[0014] Another development of the packaging according to the
invention provides for a tear-open strip to be incorporated in the
folding blank and to run substantially parallel to the lid. The
packaging may then also be provided in a filled and sealed manner
and then intentionally opened by a consumer, by said consumer
tearing off the tear-open thread and thus obviously unsealing the
packaging. It is also easy to grip beneath the lid, for example
using fingertips or fingernails, in the region of the torn-off
tear-open strip in order to open said lid. In order to facilitate
the tearing-open operation, the tear-open strip is preferably
delimited by material-weakening lines. A grip tab may be arranged
at one end of the tear-open strip for the purpose of grasping said
tear-open strip. This grip tab is preferably comfortably large
enough to enable it to be grasped in a reliable and simple manner.
In particular, the grip tab could be designed to be approximately
the size of a thumbnail. The user then does not particularly
require any distinct fine motor skills in order to grasp this grip
tab. This is particularly advantageous for elderly people. It is
therefore easier to visually identify the tear-open tap. In
addition, an embossed or punched-out area may be provided in the
grip tab in order to improve haptics.
[0015] A next development of the invention provides for a
swing-action hinge region, in which the lid remains connected to
the rear face, to be left by the tear-open strip. This therefore
produces a hinged lid which is easy to open and close again,
preferably with respect to a lid which can be lifted off entirely
and, in principle, is of course also possible.
[0016] The invention also provides for the packaging to have an
inner frame. This inner frame is substantially matched to the
tubular shape. An inner frame of this type further improves the
stability and powder-tightness of the packaging according to the
invention.
[0017] One development provides for the inner frame to protrude
beyond the extent of the tear-open strip in the direction of the
lid and remain undamaged by the tear-open strip. This also has two
advantages. Since the inner frame protrudes beyond the tear-open
strip and said tear-open strip runs at a certain distance from the
lid surface, the lid can be reclosed in a more reliable manner by
said lid being placed virtually over the protruding part of the
inner frame during the reclosing process. In order to not adversely
affect the swinging operation in the process, provision may be made
for the inner frame to be rounded in accordance with the pivot path
of a hinged lid. Since the inner frame additionally remains
unaffected by the tear-open strip, the inner frame also ensures
leak-tightness in this region too. In particular, said inner frame
forms a type of labyrinthine seal with the reclosed lid.
[0018] The inner frame may be a subregion of the folding blank of
the entire packaging, so that the packaging according to the
invention is formed virtually in two layers from a single folding
blank in substantial regions. However, the folding blank may also
be formed from two separate parts with their own folding blanks for
an outer casing and for an inner frame. In each of these two cases,
provision is preferably made for the inner frame to be adhesively
bonded to the tubular shape.
[0019] Another development of the invention proposes that a
snap-action latching connection may be provided in order to reclose
the lid, it being possible to arrange said snap-action latching
connection particularly in the region of the lid which is remote
from the swing-action hinge. The swing-action hinge could
preferably be arranged on the rear face of the packaging, while the
reclosing operation accordingly preferably takes place in the
region of the front face. However, in addition or as an
alternative, it would be entirely possible to provide closing
devices of this type in the side surface region too.
[0020] For transportation purposes, the packaging according to the
invention preferably has a carrying handle, preferably in the
region of the lid. This carrying handle could likewise be formed by
additional regions of the folding blank itself. However, provision
is preferably made for the ends of a strip-like carrying handle,
that is to say a type of lug, to be mounted in an articulated
fashion in the upper regions of the end faces. A carrying handle of
this type may be formed in a material-saving, cost-effective and
robust manner, for example from a plastic strip. This plastic strip
may, for example, be riveted to the end faces so as to be
powder-tight. It goes without saying that a wide variety of other
options for forming a carrying handle of this type are
feasible.
[0021] The packaging is preferably substantially produced from
paperboard and/or cardboard. In this case, at least part of the
packaging may be produced from corrugated board. In particular, an
inner frame is preferably produced from corrugated board, with the
corrugation peaks of the corrugated board preferably running
vertically when the packaging is assembled, so that this
corrugation additionally increases the stacking stability of the
packaging. One corrugation of this corrugated paper board may, for
example, have a corrugation height and/or a half-wave length of
approximately 1 mm. This leads to an extremely high degree of
stability on the one hand and on the other hand prevents excessive
material wear, in particular of an inner frame, which is done at
the cost of the internal volume of the packaging. However, it goes
without saying that other corrugations with different dimensions
are feasible in a variety of ways.
[0022] Within the scope of invention, it is possible for the
additional side regions to be deformed, it being possible for these
deformed edges to have a rolling shape, for example. According to
the invention, it is also feasible for the edges to have a shape
which is curved in any desired direction.
[0023] The folding box and the associated inner frame can be at
least partially adhesively bonded to one another. In this case,
said holding box and associated inner frame are adhesively bonded
to one another at the edge in the circumferential direction in such
a way that a tube which is open at the top and bottom is produced.
Since these blanks have to be transported, in order to be filled,
so that as much space as possible is saved, it is expedient to not
transport the tube in the assembled state but rather in a folded
together state. To this end, the assembled tube is bent across the
straight, uninterrupted longitudinal edges and thus folded flat in
known methods.
[0024] In the case of the packaging according to the present
invention, this is not possible, or is possible only to a limited
extent, when at least one of the vertical edges is at least
partially broken. Therefore, the invention additionally provides
for auxiliary folding lines to be provided which are arranged such
that, when the folding box is folded together, they, as a
replacement for or as a continuation of straight edges, allow the
folding box to be folded together. For filling purposes, a folding
box of this type is again assembled and then adhesively bonded at
the base. After the filling operation is complete, the lid can also
be adhesively bonded.
[0025] The auxiliary folding lines described here may be provided
both on the folding box and also on the inner frame. According to
the invention, it is also possible to provide these auxiliary
folding lines only on one of these two elements.
[0026] According to the invention, auxiliary folding lines of this
type may be provided on each desired face and in any desired
orientation. For example, said auxiliary folding lines may run on
the side walls in the longitudinal direction, that is to say from
the edge of the base to the edge of the lid. They may also be
provided centrally on the corresponding side wall.
[0027] According to the invention, the auxiliary folding lines may
be arranged such that they take over the original function of the
edges when the folding box is folded together in accordance with
the method according to the invention. This means that the tube
which is produced by the adhesive bonding operation can be folded
flat across these folding lines.
[0028] In the case of a packaging of this type, it may be
advantageous for said packaging to be of relockable design. To this
end, connection options may be provided between the lid and the
inner frame, these connection options holding said lid in its
closed position after the reclosing operation.
[0029] A connection option of this type could be formed as a
snap-action latching connection, with, for example, at least one
latching element and at least one snap-in lug being used. According
to the invention, it would be possible for the latching element to
be fitted to the inner face of the lid of the folding box and for
the snap-in lug to be fitted to the upper face of the inner
frame.
[0030] The number, shape or design of such connection options are
in no way restricted by the examples mentioned here. Instead, the
present invention covers all imaginable embodiments of a connection
option of this type.
[0031] In order to further facilitate the reclosing operation, it
may be advantageous to match the inner frame to the closing
movement of the lid. For example, the upper edges of the inner
frame could be equipped with a quarter-circle-like side termination
which sets and releases a pivot arc of the lid, so that it is
easier to close the packaging. Further possible design options for
an easier closing movement are also feasible.
[0032] The present invention is in no way restricted to the number
of individual parts of the packaging, or rather the folding box and
the inner frame. It may, for example for production reasons, be
advantageous to produce the inner frame and the folding box
integrally or from two separate blanks. In the last-mentioned
embodiment, the folding box and inner frame could be at least
partially adhesively bonded to one another during the production
process.
[0033] The invention also relates to blanks for a packaging
according to the invention and these blanks may be of both integral
or else multipartite design, for example the inner frame and
folding box may be formed as separate blanks.
[0034] Blanks of this type may be equipped with adhesive flaps in
order to improve adhesive bonding to a tube. Overlapping regions on
the walls of the folding box or the inner frame are also feasible
within the scope of the present invention.
[0035] Exemplary embodiments, which disclose further inventive
features but to which the scope of the invention is not restricted,
are illustrated in the drawing, in which:
[0036] FIG. 1 shows a blank for a first embodiment of an outer
carton of a packaging according to the invention,

[0046] FIG. 11 shows a view the packaging according to FIG. 7 from

[0047] FIG. 1 shows a first exemplary embodiment of a blank for an
outer carton of a packaging according to the invention. This blank
comprises the front face 1, the rear face 2 and the side surfaces 3
and 4 of the packaging. These four surfaces can be folded and
connected to one another to form a tubular shape, with an adhesive
flap 5 being provided for connection purposes. When the tubular
shape is closed, the vertical edge regions of the tubular shape are
formed by additional surface regions 6, of which in each case one
additional surface region 6 is arranged in the tubular shape
between two of the surfaces 1 to 4 in each case. Each of these
additional surface regions tapers to a point 7 at the top and at
the bottom, is therefore of substantially approximately pick-like,
elliptical or ship-like design.
[0048] Lid flaps 8 and base flaps 9 respectively adjoin the
surfaces 1 to 4 at the bottom and at the top.
[0049] The blank according to FIG. 1 can be folded up along
auxiliary folding lines 10 and in this way be stored or supplied to
a packaging machine. These auxiliary folding lines 10 are necessary
for this purpose since the contours of the additional surface
regions 6 run rectilinearly only in one portion but are of rounded
design in the vicinity of the points 7.
[0050] In addition to the blank for an outer carton, an inner frame
is also preferably provided for the packaging according to the
invention. This inner frame has not been illustrated in any detail
in the drawing because it can be formed in a substantially similar
manner to the blank according to FIG. 1, without the respective lid
flaps 8 and base flaps 9. The inner frame therefore substantially
has a rectangular contour. In this case, it is important with
regard to the additional surface regions 6 that the inner frame has
corresponding approximately congruent additional surface regions 6.
This inner frame may then be folded and connected to form an inner
casing tube which directly lines the outer carton and clings
tightly to this outer casing or outer carton. For improved
stability of the entire packaging, the inner frame and the outer
carton may additionally be adhesively bonded to one another in a
surface-connected or point-connected manner. The inner frame is
preferably formed from corrugated board.
[0051] A packaging whose exterior is illustrated in perspective
view in FIG. 2 can be formed from the blank according to FIG. 1.
Identical components are identified by the same reference numerals
as in FIG. 1.
[0052] FIG. 2 shows, in particular, that the lid which is formed
from the lid flaps 8 and the base which is formed from the base
flaps 9 are of quadrilateral, in particular rectangular, design
while the central body region of the packaging has an octagonal
cross section. For this purpose, the additional surface regions 6
are at angles of approximately 135.degree. in relation to the
respectively adjacent surface 1 to 4. On account of the pick-like
design of the additional surface regions 6, the edges of the
additional surface regions are bent and deformed. The respective
points 7 are involved in forming the corners of the packaging. The
packaging is easier to handle an account of the octagonal
cross-sectional shape in its middle region, in particular to be
grasped from the side surfaces 3 or 4.
[0053] FIG. 3 shows a front view of the packaging according to FIG.
2. FIGS. 4 and 5 respectively show a plan view of the packaging
according to FIG. 2 and a view of said packaging from beneath.
Identical components are again identified by the same reference
numerals as in FIG. 1.
[0054] FIGS. 4 and 5, in particular, show that the surface regions
1 to 4 are of approximately convex or outwardly curved design on
account of the deformation of the packaging in the additional
surface regions 6. In addition, FIGS. 4 and 5, as in the blank
according to FIG. 1, show that the packaging has a substantially
square lid 8 and base 9 in this exemplary embodiment.
[0055] FIG. 6 shows a second exemplary embodiment of a possible
blank for a packaging according to the invention. Identical
components are identified by the same reference numerals as in FIG.
1.
[0056] In comparison to the blank according to FIG. 1, the
additional surface regions 6 in the blank according to FIG. 6 in
particular are of very pronounced design, to be precise such that
virtually only rudiments of the side surfaces 2 remain,
specifically an actual end surface is no longer present in the
packaging produced from the blank according to FIG. 6. In the end
side regions, the additional surface regions 6 directly border one
another in this case, so that the packaging is acutely angled in
this region. This is clear in the perspective view according to
FIG. 7 which shows the packaging produced from the blank according
to FIG. 6. This packaging is therefore hexagonal in its middle
region, while small octagonal regions remain in the upper and lower
portions.
[0057] FIG. 8 shows a front view of the packaging according to FIG.
7.
[0058] FIG. 9 shows a view of the acutely angled end face 2 of the
packaging according to FIG. 7.
[0059] FIGS. 10 and 11 respectively show a plan view of the
packaging according to FIG. 7 and a view of said packaging from
beneath.
