Description

(1) Further features of the invention are apparent from the claims, the embodiment as well as based on the drawings. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the embodiments are usable not only in the respectively specified combination, but also in other combinations without departing from the scope of the invention. There shows:

(2) FIG. 1 a schematic lateral representation of a packaging according to the invention in closed state;

(3) FIG. 2 a schematic representation of the packaging according to FIG. 1 from the front;

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

(5) FIG. 4 a schematic detailed representation of the blank shown in FIG. 3.

(6) FIG. 1 shows a schematic representation of a packaging 10, which in particular serves for the storage and the transport of packaged or unpackaged pourable, powdery and free-flowing foods or detergents. However, liquids can also be stored in correspondingly liquid-tight intermediate packagings in the packaging 10. Therein, the packaging 10 comprises a front wall 12 and a rear wall 14, which are connected via each three sidewalls 22, 22′, 22″, 24, 24′, 24″ (see also FIGS. 2 and 3). The sidewalls 22, 22′, 22″, 24, 24′, 24″ constitute the end sides 16, 18 of the packaging 10. One recognizes that the packaging 10 is formed in the shape of a prismatic body along a longitudinal axis L extending parallel to the longitudinal extension of the front and rear walls 12, 14 and has an octagonal base surface 38. In addition, the packaging 10 comprises a bottom construction 20, which comprises each one bottom flap 26, 28 hinged to the front and rear walls 12, 14 for bottom-side closure of the packaging 10 (see also FIG. 3). Furthermore, the packaging 10 comprises a lid construction 30, wherein the lid construction 30 includes each one lid flap 32, 34 hinged to the front and rear walls 12, 14 for lid-side closure of the packaging.

(7) One recognizes that the lid flaps 32, 34 each include two sectional areas 32′, 32″, 34′, 34″, wherein a first sectional area 32″, 34″ respectively hinged to the front and rear walls 12, 14 is formed widening towards the adjoining second sectional area 32′ (not illustrated), 34′. The bottom flaps 26, 28 are correspondingly formed (not illustrated). Furthermore, one recognizes that the lid flaps 32, 34 are additionally formed such that they completely cover the area of a base surface 38 of the packaging 10 formed as a prismatic body formed by the sidewalls 22, 22′, 22″, 24, 24′, 24″ arranged on the end side in the closure position of the packaging 10. The same applies to the bottom flaps 26, 28 (not illustrated).

(8) In addition, it becomes clear that the bottom and lid flaps 26, 28, 32, 34 are formed such that they rest on the sidewalls 22, 22′, 22″, 24, 24′, 24″ connecting the front and rear walls 12, 14 at least in certain areas and protrude beyond at least one of the sidewalls 22, 22′, 22″, 24, 24′, 24″ in certain areas in the illustrated closure position of the packaging 10. Thereby, considerable increase of the shape stability of the packaging 10 arises. In addition, secure closure of the packaging 10 is ensured. In order to constructively achieve this, a width a of the lid flaps 32, 34 hinged to the front or rear wall 12, 14 as well as the corresponding bottom flaps 26, 28 is larger than a width b of the front and rear walls 12, 14 in the area of the respective hinge of the lid and bottom flaps 32, 34. Therein, the width b corresponds to the length of the bending lines 66, 70, which are formed between the front wall 12 and the lid flap 32 and the rear wall 14 and the lid flap 34, respectively. The same applies to the bending lines 74, 78, which are formed between the front wall 12 and the bottom flap 26 and the rear wall 14 and the bottom flap 28, respectively (see also FIG. 3).

(9) In addition, it becomes clear from FIG. 1 that the packaging 10 has an octagonal base shape 38. In order to achieve this, the front wall 12 is connected to respective sidewalls 22′, 24′ via corresponding bending lines 56, 60, wherein the sidewalls 22′, 24″ are in turn connected to the sidewalls 22, 24 via bending lines 54, 62 and they are connected to the sidewalls 22″, 24′ via the bending lines 52, 64 (compare also FIG. 2). The side walls 22″, 24′ are in turn connected to the rear wall 14 via corresponding bending lines 50, 82 (compare also FIG. 3). Therein, it is to be noted that the sidewall 24′ is also connected to an adhesive flap 58 via the bending line 64, wherein the adhesive flap 58 is adhered to an inner side of the side wall 24 for producing the packaging 10 (not illustrated).

(10) Furthermore, one recognizes that a grooving line 90 is formed in the sectional area 34″ of the lid flap 34. This grooving line 90 extending parallel to the front and rear walls 12, 14 serves for stability increase of the lid flap 34. In an area below the lid construction 30, a tear-off flap 44 is additionally formed. Therein, the tear-off flap 44 is formed by means of the perforation lines 92, 94 extending parallel to each other in the area illustrated in FIG. 1.

(11) FIG. 2 shows a further schematic representation of the packaging 10 according to FIG. 1 in a representation from the front. One again recognizes the overall octagonal configuration of the base surface 38 of the packaging 10. In addition, it becomes clear that the tear-off flap 44 terminates in a grip flap 96, wherein the grip flap 96 protrudes beyond the circumference of the packaging 10. The side surface 24 comprises a perforation 46 in the area and at the level of the tear-off flap 44, which detaches the lid construction 30 from the packaging 10 in this area after tearing the tear-off flap 44 and thus contributes to opening of the packaging 10. The perforation 46 transitions into a grooving line 84 on the rear side 14 (compare FIG. 3), which serves as a type of hinge for the lid construction 30. From FIG. 2, it again becomes clear that the bottom and lid flaps 26, 28, 32, 34 are formed such that they rest on the sidewalls 22, 22′, 22″, 24, 24′, 24″ connecting the front and rear walls 12, 14 in certain areas and protrude beyond them at least in certain areas.

(12) FIG. 3 shows a schematic representation of a blank 48 of the packaging 10 according to FIG. 1. The blank 48 includes front wall, rear wall and sidewall elements 12, 14, 22, 22′, 22″, 24, 24′, 24″ connected via bending lines 50, 52, 54, 56, 60, 62, 64, 82 for forming the packaging 10 as a prismatic shape body in the folded state of the blank 48 (see FIGS. 1 and 2). One recognizes that the blank 48 comprises each one lid and bottom flap 32, 34, 26, 28 hinged to the respective front and rear wall elements 12, 14. A central dust flap 36 and lateral dust flaps 40, 42 are respectively hinged to the respective ends of the sidewalls 22, 22′, 22″, 24, 24′, 24″ via corresponding bending lines 68, 72, 72′, 76, 80, 80′. The lid and bottom flaps 32, 34, 26, 28 are connected to the corresponding front and rear wall elements 12, 14 via corresponding bending lines 66, 70, 74, 78. In addition, an adhesive flap 58 is hinged to the sidewall element 24′ via the bending line 64.

(13) One recognizes that the bottom flap 26 hinged to the front wall element 12 as well as the lid flap 32 as well as also the bottom flap 28 hinged to the rear wall 14 and the corresponding lid flap 34 are respectively formed such that they rest on at least one of the sidewall elements 22, 22′, 22″, 24, 24′, 24″ connecting the front and rear wall elements 12, 14 at least in certain areas and protrude beyond at least one of these sidewall elements 22, 22′, 22″, 24, 24′, 24″, on which they rest, at least in certain areas in a closure position of the packaging 10 produced from the blank 48 (compare also FIGS. 1 and 2). In order to ensure this, the width a of the bottom flaps 26, 28 hinged to the front and rear wall elements 12, 14 and the lid flaps 32, 34 hinged to the front and rear wall elements 12, 14, respectively, is larger than the width b of the corresponding front and rear wall elements 12, 14 in the area of the respective hinge of the bottom and/or lid flaps 26, 28, 32, 34. In addition, it becomes clear that the bottom and lid flaps 26, 28, 32, 34 are each formed separated from the lateral dust flaps 40, 42 via corresponding cutting lines 86, 88, wherein the cutting lines 86, 88 are formed extending at an angle of circa 45 degrees or circa 135 degrees starting from the respective bending lines 68, 72, 72′, 78, 80, 80′ of the corresponding sidewall elements 22′, 22″, 24′, 24″.

(14) In addition, it becomes clear from FIG. 3, that the bottom and lid flaps 26, 28, 32, 34 each include two sectional areas 26′, 26″, 28′, 28″, 32′, 32″, 34′, 34″, wherein a first sectional area 26″, 28″, 32″, 34″ hinged to the front or rear wall element 12, 14 is formed widening towards the adjoining second sectional area 26′, 28′, 32′, 34′.

(15) In addition, the configuration of the tear-off flap 44 becomes clear from FIG. 3. The tear-off flap 44 is in particular defined by the two perforation lines 92, 94. The tear-off flap 44 transitions into the grooving line 84 in the area of the rear wall element 14, which in turn transitions into a perforation 46, which is formed in the sidewall element 24′ and the adhesive flap 58 in the illustrated embodiment. At the end opposing the perforation 46, the tear-off flap 44 terminates in the grip flap 96. From FIG. 3 too, the formation of the grooving lines 90 in the bottom flap 28 and the lid flap 34 is apparent. Further grooving lines 98 are formed in the central dust flaps 36 and herein too again serve for improving the stability of this element or this area of the blank 48 and the packaging 10, respectively.

(16) FIG. 4 shows a schematic detailed representation of the blank shown in FIG. 3. One recognizes that the end of the sectional area 32″ of the lid flap 32 only terminates in the area of the sidewall element 24″. Therefore, the cutting line 86 intersects the bending line 72, which in turn connects the sidewall element 24″ to the lateral dust flap 40. In addition, a slight offset of the bending line 70, via which the lid flap 32 is hinged to the front wall 12, to the bending line 72 is apparent.

(17) Thereby, a type of overhang of the lid flap 32 arises in this area, wherein this overhang serves to protrude beyond the corresponding sidewall element 24″ in the assembled state of the packaging 10. The same applies to the other end of the lid flap 32. The further lid flap 34 as well as the bottom flaps 26, 28 have constructions identical hereto.

(18) The embodiments of the packaging 10 and the blank 48, respectively, described in the preceding figures serve for clarifying the basic principle of the present invention. In particular, a plurality of differently formed packagings is conceivable. Thus, the base surfaces 38 of the packaging 10 formed as a prismatic body can be formed not only in octagonal, but also in tetra-, penta-, hexa-, hepta-, nona-, deca- or dodecagonal manner. However, other shapes are also possible.

(19) The above described packagings are formed as folding boxes. They are in particular composed of cardboard, paper, plastic or comparable materials like the associated blanks.
