Description

(1) Further features of the invention can be gathered from the claims, from the exemplary embodiments and with reference to the drawings. The features and combinations of features mentioned above in the description, and also the features and combinations of features mentioned hereinbelow in relation to the exemplary embodiments, can be used not only in the combination specified in each case, but also in other combinations, without there being any departure from the framework of the invention. In the drawings:

(2) FIG. 1 shows a schematic illustration of a packaging according to the invention;

(3) FIG. 2 shows a further schematic illustration of the packaging according to FIG. 1;

(4) FIG. 3 shows a schematic illustration of a blank according to the invention for the packaging according to FIG. 1; and

(5) FIG. 4 shows a schematic illustration of a detail of the blank shown in FIG. 3;

(6) FIG. 5 shows a schematic illustration of a blank according to the invention for the packaging according to a further embodiment; and

(7) FIG. 6 shows a schematic illustration of a detail of the blank shown in FIG. 5.

(8) FIG. 1 shows a schematic illustration of a packaging 10, which serves in particular for storing and transporting packaged or non-packaged free-flowing goods. The goods here can be, for example, cereals, cornflakes or other pourable and free-flowing foods, or also washing powder and the like. However, it is also possible to store liquids, in appropriately liquid-tight intermediate packagings, in the packaging 10. The packaging 10 here has a base wall 12 and a top wall 14, which are connected via in each case three connecting front and rear walls 22, 22′, 22″, 24, 24′, 24″. The front and rear walls 22, 22′, 22″, 24, 24′, 24″ here form a front end side 16 and a rear end side 18 of the packaging 10. It can be seen that the packaging 10 is designed in the form of a prismatic body along a longitudinal axis running parallel to the base wall and top wall 12, 14. The cross-sectional surface 78 of the packaging 10 is generally of octagonal design in a direction perpendicular to said transverse axis. In addition, the packaging 10 has in each case one side flap 26, 28, which is articulated on the base wall and the top wall 12, 14 and is intended for closing the packaging 10 laterally (see also FIG. 2). The packaging 10 also comprises a total of four dust flaps 36 (see FIG. 3), which are each articulated on the front walls 22, 24 via folding lines 74, 76. The dust flaps 36 serve to close the packaging 10 laterally in the region of the front and rear end sides 16, 18. Furthermore, the top wall 14 has a tear-open flap 20, which is delimited in the top wall 14 via corresponding perforation lines 38, 40. In the region of an adhesive-bonding flap 58, which is articulated on the top wall 14 via a folding line 52, the tear-open flap 20 merges into a grip flap 88, which is defined via perforation lines 84, 86 formed in the adhesive-bonding flap 58. For easier opening of the tear-open flap 20, a cut line 80 is formed adjacent to the folding line 52, and within the grip flap 88, and serves to form a pull tab 82. It can be seen that the pull tab 82 projects slightly beyond the outlines of the prismatic body of the packaging 10 and is thus easy to grip.

(9) It is also evident that the side flaps 26, 28 are designed such that, in the respective closed position, they rest, in part, on the front and rear walls 22′, 22″, 24′, 24″ connecting the bottom and top walls 12, 14 (also compare FIG. 3) and project beyond the same. For this, the side flaps 26, 28 have in their respective corner regions in each case an overhang 44, which in the closed position of the packaging 10 shown projects beyond said front and rear walls 22′, 22″, 24′, 24″, at least in part. It is evident that resting noses 30, 32 are respectively formed at the opposite ends of the respective overhangs 44. It is clear that the side flaps 26, 28 are designed such that, in the closed position of the packaging 10, they almost completely cover over the region of the cross-sectional surface 78 that is formed by the front and/or rear walls 22, 22′, 22″, 24, 24′, 24″ arranged at the end sides. It is also evident that the cross-sectional surface 78 is formed perpendicularly to the longitudinal axis L. According to further embodiments of the packaging 10, it is however also possible that two or more side flaps are respectively designed such that, in the closed position, they completely or at least partially cover over the region of the cross-sectional surface 78 that is formed by the front and rear walls 22, 22′, 22″, 24, 24′, 24″ arranged at the end sides.

(10) Furthermore, it is evident that a dust flap 36 is respectively articulated on the front wall 22 and also the rear wall 24 via the folding lines 76, 74. Via the folding line 54, the rear-wall element 24′ is articulated on the top wall 14 or the tear-open flap 20. The side flaps 26, 28 are respectively articulated on the base wall 12 via folding lines 70, 72 (see also FIG. 2). Arranged parallel to the folding lines 70, 72 are folding lines 34. Via the folding lines 34, an adhesive-bonding or insertion flap 26′, 28″, is respectively formed as a sub-region of the respective side flaps 26, 28. Furthermore, it is evident from FIG. 1 that the adhesive-bonding flap 58 comes to lie on the front wall 22″, and is adhesively bonded to said wall, at least in part.

(11) In the exemplary embodiment illustrated, the front end side 16 is formed by the front walls 22, 22′, 22″ (see also FIG. 3), which are connected to one another via corresponding folding lines 64, 66, 68. The front wall 22″ here is connected to the adhesive-bonding flap 58. The rear end side 18 is formed by the rear walls 24, 24′, 24″, which are connected to the top wall 14 and the base wall 12 via corresponding folding lines (see also FIG. 3).

(12) FIG. 2 shows a further schematic illustration of the packaging 10 according to FIG. 1. Evident once again is the overall octagonal configuration of the packaging 10, which lies horizontally on the base wall 12. It is also clear that the side flap 28 is connected to the base wall 12 via the folding line 22. The configuration of the overhangs 44 and of the resting noses 30, 32 means that there is a secure closure and a significant increase in stability of the packaging 10 in the regions of the front and rear end sides 16, 18 of the packaging 10. It is clear that even a deformation of the packaging 10 in these regions can be compensated to a certain degree without any problems. The overhang 44 or the resting noses 30, 32 can compensate for deformations in this region to some degree, and nevertheless still lie against the corresponding front or rear walls 22′, 22″, 24′, 24″.

(13) As far as the description of the rest of the features illustrated in FIG. 2 is concerned, reference is made to the description relating to FIG. 1.

(14) FIG. 3 shows a schematic illustration of a blank 50 of the packaging 10 according to FIG. 1 or FIG. 2. The blank 50 comprises base-wall, top-wall, front-wall and rear-wall elements 12, 14, 22, 22′, 22″, 24, 24′, 24″, which are connected via folding lines 52, 54, 56, 60, 62, 64, 66, 68 and are intended for forming the packaging 10 in the form of a prismatic body in the folded state of the blank 50 (see also FIGS. 1 and 2). It can be seen that the blank 50 comprises a respective dust flap 36, which is articulated at the ends of the front-wall element 22 and of the rear-wall element 24. The dust flaps 36 are each articulated the front-wall and rear-wall element 22, 24 via corresponding folding lines 74, 76. In addition, an adhesive-bonding flap 58 is articulated on the top-wall element 14 via the folding line 52.

(15) It can be seen that the side flaps 26, 28 are designed such that, in the folded state of the blank 50 and in a closed position of the packaging 10, rest on the front and rear walls or front-wall and rear-wall elements 22′, 22″, 24′, 24″ and project beyond the same. In order to achieve this, a width a of the side flaps 26, 28 in the region of their respective articulation on the base-wall and/or top-wall element 12, 14 is greater than a width b of the base-wall or top-wall element 12, 14 in said region. This results in a kind of overhang 44 in the non-articulated region of the side flaps 26. The respective overhangs 44 then project beyond the front and rear walls 22′, 22″, 24′, 24″ in the folded state of the blank 50 and in the closed position of the packaging 10. In the exemplary embodiment illustrated, the side flaps 26, 28 are designed such that the side region connecting the overhangs 44 merely rests on the respective front and rear walls 22, 24 and does not project beyond them.

(16) Furthermore, it is evident that the side flaps 26, 28 in the exemplary embodiment illustrated are altogether of an approximately octagonal design. Moreover, it is clear that the side flaps 26, 28 respectively have two sub-regions 26′, 26″, 28′, 28″. The first sub-regions 26′, 28′ are respectively connected here via folding lines 70, 72 to the base-wall element 12 of the blank 50. Via folding lines 34, which run parallel to the folding lines 70, 72, the respective second sub-region 26″, 28″ is articulated on the corresponding first sub-regions 26′, 28′. The second sub-regions 26″, 28″ here can be designed in the form of an insertion and/or adhesive-bonding flaps.

(17) In addition, the top-wall element 14 of the blank 50 has a tear-open flap 20, which is formed via the perforation lines 38, 40. In the region of the adhesive-bonding flap 58, the tear-open flap 20 is continued in a grip flap 88, which is formed via the perforation lines 84, 86. For easier opening of the tear-open flap 20, use is made of the pull tab 82, which is formed by means of the cut line 80.

(18) FIG. 4 shows a schematic illustration of a detail of the blank 50 shown in FIG. 3. It is evident that the side flap 28 respectively has in its corner regions the overhangs 44 and also the resting noses 30, 32. For forming the overhang 44, a cut line delimiting the resting noses 30, 32 and also the overhang 44 projects into the region of the rear-wall element 24″. This means that the said cut line does not cut the folding line 72, which connects the base wall element 12 to the side flap 28. Furthermore, it is evident that the dust flap 26 is articulated via the folding line 74 on the rear-wall element 24, which is connected to the further rear-wall element 24″ via the folding line 60.

(19) FIG. 5 shows a schematic illustration of a blank 50 of the packaging 10 according to a further embodiment. As a difference from the exemplary embodiment of the blank shown in FIG. 3, this exemplary embodiment shows a blank 50, in which the dust flaps 36 are not articulated on the front-wall or rear-wall element 22, 24 but on a non-articulated region of the side flaps 26, 28 via corresponding folding lines 42, 46. The dust flaps 36 may in this case also be used as insertion and/or adhesive-bonding flaps. It is clear that the side flaps 26, 28 nevertheless have the overhangs 44 with the corresponding resting noses 30, 32. For forming the overhangs 44, once again the width a of the side flaps 26, 28 in the region of their respective articulation on the base-wall or top-wall element 12, 14 is greater than the width b of the base-wall or top-wall element 12, 14 in said region. With respect to the description of the further features illustrated in FIG. 5, reference is made to the description relating to FIG. 3.

(20) FIG. 6 shows a schematic illustration of a detail of the blank 50 shown in FIG. 5. It is evident that, in the case of this exemplary embodiment, the dust flap 36 is connected to the side flap 26 via the folding line 42. For forming the overhang 44 and also the resting noses 30, 32, the side flap 26 is once again configured in its corner regions in such a way that a cut line delimiting the overhang 44 and also the resting noses 30, 32 does not cut the folding line 70, which connects the base wall element 12 to the side flap 26. Furthermore, it is clear that the front-wall element 22 in the exemplary embodiment illustrated does not have a side flap but is merely delimited by a cut line 48.

(21) Those exemplary embodiments of the packaging 10 and of the blanks 50 which are described in the figures above serve to clarify the basic principle of the present invention. In particular, a large number of differently designed packagings are conceivable. It is therefore possible for the cross-sectional surfaces 78 of the prismatic-body-design packaging 10 to be of not just octagonal design, but also of quadrilateral, pentagonal, hexagonal, heptagonal, nonagonal, decagonal, hendecagonal or dodecagonal design. However, other shapes, for example round shapes or combinations of round and polygonal shapes or triangular configurations, are also possible.

(22) The packagings described above are designed in the form of folding boxes. They, like the associated blanks, consist, in particular, of cardboard, paper, plastic or comparable materials.
