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. 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 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 L running parallel to the base wall and top wall 12, 14 and to the front wall and rear wall 22, 24. The cross-sectional surface 38 of the packaging 10 is of octagonal design in a direction perpendicular to said longitudinal axis. The longitudinal axis L therefore runs parallel to a bearing surface of the packaging 10. In the case of the prior-art packagings mentioned in the introduction, the respective longitudinal axes run perpendicularly to the corresponding bearing surfaces.

(7) 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, 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 46, 48. 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, 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.

(8) It can also be seen that the dust flaps 36 are designed such that, in the respective closed position, they rest, at least in part, on the front and rear walls 22′, 22″, 24′, 24″ on which it is not articulated, and project beyond the same at least in part. It is also the case that the dust flaps 36 comprise in each case two opposite latching noses 44, which, in the closed position, each latch in corresponding recesses 30, 32 formed in the side flaps 26, 28. The recesses 30 here are formed in a transition region between the base wall 12 and the respective side flap 26, 28. The recesses 32 are formed in the transition region between the top wall 14 and the corresponding side flaps 26, 28. It can be seen that the recesses 30 are formed at the respective ends of a folding line 70, and the recesses 32 are formed at the respective ends of a folding line 34. The folding line 70 here forms the transition between the base wall 12 and the side flap 26; the bending line 34 connects a first portion 26′ of the side flap 26 to an insertion and/or adhesive-bonding flap 26″ (see also FIG. 3). It can also be seen that the latching noses 44 also each project beyond the actual prismatic body of the packaging 10.

(9) 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 54, 62 (see also FIG. 3).

(10) 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 clear that the dust flaps 36 are formed identically on four sides of the packaging. The dust flaps 36, once again, latch in the recesses 30, 32 by way of the latching noses 44. It can be seen that the side flap 28 has the corresponding recesses 30, 32, the latter being formed at the respective ends of the folding lines 72, 34. The folding line 72 here connects the base wall 12 to the side flap 28; the folding line 34 connects a first region 28″ of the side flap 28 to a second region 28″, which is designed in the form of an insertion and/or adhesive-bonding flap (see also FIG. 3). 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.

(11) 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 are each articulated on the front-wall and rear-wall elements 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.

(12) It can be seen that the dust flaps 36 comprise in each case two opposite latching noses 44, wherein the latching noses 44 are designed such that, in the folded state of the blank 50 and in the closed position of the dust flap 36, they butt against the front-wall and rear-wall elements 22′, 22″, 24′, 24″ and also sub-regions of the base-wall and of the top-wall elements 12, 14. In addition, it is clear that the length of the respective folding lines 74, 76 is smaller than the length and width of the respective dust flaps 36 in this region. This means that the respective dust flap 36 projects on either side beyond the articulation. The boundary lines of the respective first portions 40 of the dust flaps 36 here are designed to run at an angle of approximately 45°, or approximately 135°, starting from the respective folding line 74, 76 of the corresponding front-wall or rear-wall element 22, 24.

(13) In addition, it is clear from FIG. 3 that the dust flaps 36 comprise a respective first portion 40, wherein the first portion 40 is articulated on the corresponding front-wall or rear-wall element 22, 24, and is designed such that, in the folded state of the blank 50 and in the closed position of the dust flap 36, it covers over that region of the cross-sectional surface 38 prismatic-body-design packaging 10 which is formed by the front-wall and rear-wall elements 22, 22′, 22″, 24, 24′, 24″, which are arranged on the end sides. In addition, in the exemplary embodiment illustrated, the dust flaps 36 have a second portion 42, which adjoins the first portion 40, wherein the second portion 42 is designed such that, in the folded state of the blank 50 and in the closed position of the dust flap 36, it butts against the inner sides of the base-wall and top-wall elements 12, 14. However, it is also possible for further latching noses to be formed in the first portion 40 and/or the second portion 42.

(14) Furthermore, it is clear that the recesses 30, 32 are formed at the opposite ends of the respective folding lines 70, 72, 34. The folding line 34 here connects the first portion 26′, 28′ of the respective side flap 26, 28 to the corresponding second portion 26″, 28″ of the respective side flap 26, 28. The second portion 26″, 28″ here can be designed in the form of an insertion and/or adhesive-bonding flap.

(15) In addition, the top-wall element 14 of the blank 50 has a tear-open flap 20, which is formed via the perforation lines 46, 48. 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.

(16) FIG. 4 shows a schematic illustration of a detail of the blank 50 shown in FIG. 3. It can be seen that the dust flap 36 has its first portion 40 articulated on the front-wall element 22 via the folding line 74. The dust flap 36 here is designed to be wider and longer in this region than the folding line 74 and therefore projects into a region of the further front-wall element 22′. This results in something of an overhang of the dust flap 36 in this region, said overhang serving to project beyond the corresponding front-wall element 22′ when the packaging 10 is in the joined-together state. The same applies to the opposite end (not illustrated) of the dust flap 36 and to all other dust flaps 36 of the blank 50. The design of all other dust flaps is identical to this.

(17) 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 38 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, are also possible.

(18) 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.
