Description

  The present invention relates to a three-dimensional structure of paper, cardboard, or plastic, in particular, a blank for producing a packaging or the like, and the blank is a region of a rounded edge of the three-dimensional structure with the blank folded. At least one fold surface, the fold surface being bounded by fold lines on two side surfaces extending parallel to each other. Furthermore, the invention relates to a method for producing a three-dimensional structure of paper, cardboard or plastic, a folding box for storing goods, in particular a folding box for cardboard, paper or the like, and a blank.

  Such blanks, three-dimensional structures and folding boxes are very well known. Among these, these blanks, or the three-dimensional structure and the folding box are each a flip-type pack that is a typical packaging form widely used for cigarettes and the like. Thus, German Patent Application Publication No. 431568 (A1), European Patent Application Publication No. 2141090 (A1), German Patent Application Publication No. 10106547 (A1), US Pat. No. 6,276,600 (B1), and German Patent Application No. 60028078 ( No. T2) describes a prism-shaped packaging in which a lid is connected to a container-like storage area in a hinged manner, and a main body follows a longitudinal axis. From WO 2012/123189 (A1) a folding box with a rounded edge region is known. Rounded edge regions are created by multiple cuts in these regions. A plurality of individual faces are created by the cuts and can be folded entirely to form rounded areas.

German Patent Application Publication No. 10 2008 061661 (A1) International Publication No. 2012/123189 (A1)

  However, this known packaging is disadvantageous in that multiple cuts are required to form a rounded area. The preparation of the corresponding punching tool is very time consuming and thereby expensive. Due to the need for a plurality of cut lines, generation by laser energy is also relatively time consuming and requires a lot of energy.

  Thus, a general blank to produce a three-dimensional structure of paper, cardboard or plastic, corresponding three-dimensional structure, paper, which can be manufactured and implemented easily, quickly and inexpensively, respectively It is an object of the present invention to provide a corresponding folding box of cardboard or plastic and a method for manufacturing said blank.

  A blank having the features of claim 1, a three-dimensional structure having the features of claim 9, a folding box having the features of claim 12, and a method having the features of claim 15 to solve these objectives. used. Advantageous developments of the advantageous development of the invention are specified in the respective dependent claims. Here, the advantageous configuration of the blank is regarded as the advantageous configuration of each of the three-dimensional structure according to the invention and the folding box according to the invention, and the advantageous configuration of the method according to the invention, and vice versa.

  A first aspect of the present invention relates to a three-dimensional structure of paper, cardboard, or plastic, in particular, a blank for producing a package or the like. The blank is rounded in a state in which the blank is folded. It includes at least one fold surface to form a banded edge region, the fold surface being bounded by two side fold lines extending parallel to each other. According to the present invention, at least one crease line extending at an angle with respect to the side fold line is formed in the fold line. Surprisingly, it can be seen that such a creased line can already generate a rounded region of the three-dimensional structure in a state in which the blank is bent accordingly. Thereby, the time consumption for preparing the corresponding punching or crease tool for constructing the crease line can be considerably reduced. Furthermore, compared to known blanks, the laser that generates the creases according to the invention and thereby must be consumed to construct a rounded area of an exemplary package, in particular a cigarette package. The energy is quite low. For example, known blanks have 5 to 7 fold lines extending parallel to the fold line that is the boundary of the side of the fold surface. By constructing the crease lines according to the invention in the folding plane, the number of crease lines can be considerably reduced. Thus, besides the corresponding cost savings, the production rate can also be 25 to 75% faster than conventional blanks. Here, the crease line for generating the rounded edge region is a cut line, i.e. a cut completely penetrating the blank or blank substrate, or a blank or blank substrate completely. It can be formed as a linear recess that does not penetrate, so-called “half cut”. Furthermore, the crease lines can be arranged inside the blank or in the folded state, ie inside and / or outside the resulting folding box. Here, the crease line and / or the side fold line are formed, for example, inside or outside the blank. However, different crease lines and / or side fold lines can be arranged on different sides, i.e. on the front side and / or on the back side of the blank, thereby providing particular features for the folding box with the blank folded It is also possible to attach various patterns.

  In a further advantageous configuration of the blank according to the invention, the side fold lines and crease lines are generated by laser energy and / or punching. By limited or at least partial use of laser energy to produce a blank, the corresponding blank element can be produced very accurately and quickly. Furthermore, the configuration of the individual elements can be changed particularly simply and quickly, for example, without having to create new punching or embossing tools. Furthermore, the present invention provides the advantage that less powerful or slower lasers can be used to generate the creases according to the present invention, which is a considerable cost advantage for blank manufacturing. Manufacturing and production speeds are much higher due to the fact that much less creases are required compared to known blanks for forming the rounded edge regions of the three-dimensional structure produced from the blank.

  In a further advantageous configuration of the blank according to the invention, the crease line formed in the folding surface opposes the first end and / or corner region of the folding surface and the first end and / or corner region. It extends between the second end and / or corner area of the folding surface. However, the crease line is formed between the first end and / or corner region of the folding surface and the second end and / or corner region opposite to the first end and / or corner region. It is also possible to extend between them. Further, the crease line may be outside the first end and / or corner region of the folding surface, and at the second end and / or corner region of the folding surface opposite the first end and / or corner region. It can be formed in the outer folding surface. With the configuration of the crease lines according to the invention, it is also conceivable that the crease lines extend very differently in the folding plane with respect to the final configuration of the rounded edge region of the three-dimensional structure. Thereby, the corresponding design specifications can also be easily satisfied.

  In a further advantageous configuration of the blank according to the invention, at least one end of the crease line intersects or is adjacent to the fold line on the side of the corresponding fold surface. Again, the configuration of the crease lines in the folding plane can satisfy the corresponding manufacturing and / or design specifications.

  In a further advantageous configuration of the blank according to the invention, the folding surface is divided into at least two partial areas by at least one crease line, each partial area being formed in a triangular shape. Due to the triangular shape of the partial area, the roundness is particularly conveniently constructed in the folded state of the blank. Here, further crease lines can be formed in at least one of the partial areas so that a particularly clean rounded structure can be formed in these areas.

  In a further advantageous configuration of the blank according to the invention, the crease lines are formed in a straight line, folded, wavy, winding, stepped or a corresponding combination thereof. Further, the crease lines can be formed as continuous or discontinuous crease lines between the side fold lines. Thereby, also in this case, a plurality of design requirements can be conveniently satisfied.

  A second aspect of the invention relates to a three-dimensional structure of paper, cardboard or plastic produced by folding and / or adhering a blank as described above. The possible configuration and advantages of the three-dimensional structure thus generated arises from the possible configuration and advantages of the blank according to the invention according to the first aspect of the invention. Here, the three-dimensional structure can be configured as a package, particularly a package for storing cigarettes.

  The third aspect of the present invention relates to a folding box for storing items, and more particularly to a folding box such as cardboard or paper. Here, the folding box has at least one front wall, at least one rear wall, and at least one first and second side walls for connecting the front wall and the rear wall, and a bottom side of the folding box. A bottom structure for closing and a plurality of folding surfaces for forming a rounded edge region, each one of the folding box. Here, according to the present invention, the at least one folding surface is bounded by the side folding line, and at least one folding line extending at an angle with respect to the side folding line is formed in the folding surface. . Such a folding box is known because it only needs to have one or at least one crease line in each corresponding folding plane in order to constitute the rounded edge region of the folding box. Compared to a folding box having a rounded edge region, it can be manufactured at a much lower cost. Significant time and cost advantages arise both when mechanically generated by punching, crease and embossing, and when using laser energy to generate creases.

  In a further advantageous configuration of the folding box according to the invention, at least one end of the crease line intersects or is adjacent to the folding line on the side of the corresponding folding surface. Further, the crease lines can be formed as continuous or discontinuous crease lines between the side fold lines. These configurations of the crease lines in the folding plane can also easily and inexpensively generate the rounded edge region of the folding box. Furthermore, very different design requirements for these areas of the folding box can be easily met. Furthermore, the crease lines can be arranged inside and / or outside the folding box. Here, all of the crease lines and / or the side fold lines are formed inside or outside the folding box, for example. However, different crease lines and / or side fold lines can be arranged on different sides, i.e. inside and / or behind the folding box, thereby giving the folding box a specific characteristic pattern Is also possible.

  Further features and advantages of the present invention are apparent from the description of the first and second aspects of the invention, and the advantageous configuration of the first and second aspects of the invention is the advantageous configuration of the third aspect of the invention. As vice versa, and vice versa.

  A fourth aspect of the present invention relates to a method for producing a blank as described above. Here, the outer contour of the blank and / or the fold line and / or the cutting line and / or the inner contour and / or the crease of the blank can be generated by laser energy according to the invention. By limited or at least partial use of laser energy to produce a blank, the corresponding blank element can be produced very accurately and quickly. Furthermore, the configuration of the individual elements can be changed particularly simply and quickly, for example, without having to create new punching or embossing tools.

  Further advantages, features, and details of the present invention will be apparent from the description of the following two embodiments and the description based on the drawings. The features and combinations of features described above in this description, and the following features and combinations of features shown only in the description of the drawings and / or in the drawings, are used only for each specific combination without departing from the scope of the invention. Can be used as well as other combinations or alone.

1 is a schematic view of a blank according to the present invention according to a first embodiment. FIG. 3 is a schematic view of a blank according to the present invention according to a second embodiment.

  FIG. 1 is a schematic view of a blank 10 for generating a three-dimensional structure of cardboard. Here, the three-dimensional structure is a package, in particular a folding box. Here, in a state where the blank 10 is folded (not shown), the blank includes folding surfaces 50, 52, 54, 56 and folding lines 82, 84 in order to form at least one container-like storage area. Wall and bottom elements 12, 14, 16, 26, 28, 30, 32 connected via each other. Further, in order to form the closing lid 92 in a state where the blank 10 is folded (not shown), the rear wall 16 is connected to the first lid wall 22 via the folding line 86, and the first lid wall 22 is formed. It will be appreciated that is connected to the second lid wall 18 via a fold line 88, and the second lid wall 18 is connected to the third lid wall 20 via a third fold line 90. . Further, the first lid wall 22 is connected to the lid side walls 34 and 36 via the bent surfaces 54 and 56. The third lid wall 20 is connected to further lid side walls 38, 40 via folding edges 58, 58 '. Further, the adhesive flaps 46 and 48 are formed on the lid side walls 34 and 36 via the folding lines 94 and 96, and are bonded in contact with the inside of the second lid wall 18 when the blank 10 is folded. The third lid wall 20 further has a fold line 92 ′ on the opposite side of the second lid wall 18 and is connected to a further adhesive flap 24 via the fold line 92 ′.

  It will be appreciated that the folding surfaces 50, 52 are bounded by side fold lines 60, 62, 64, 66. Here, the two crease lines 70 and 72 are formed in the folding surface 50 and extend at an angle with respect to the side folding lines 60 and 62, respectively. Here, the crease line 70 includes the first end and / or corner region 120 of the bending surface 50 and the second end and / or corner region 122 facing the first end and / or corner region 120. It extends between the areas away from. This region is located on the side fold line 60. Here, the crease line 70 intersects or is adjacent to the fold line 60. In contrast, the second crease line 72 formed on the fold surface 50 is from the second end and / or corner region 122 toward the intersection of the first crease line 70 and the side fold line 60. It extends and is adjacent to the end of the corresponding first crease line 70. Due to the configuration of the crease lines 70 and 72, three partial regions 106, 108 and 110 are generated in the bending surface 50. Each of these partial areas is formed in a triangular shape, and as a result, the folded blank 10 has a rounded edge area. Similarly, only one crease line 68 is formed on the folding surface 52 adjacent to the front wall 12. This extends between the first end and / or corner region 120 of the folding surface 52 and the second end and / or corner region 122 of the folding surface 52 opposed thereto. This configuration results in two partial areas 102, 104 that are also formed in a triangular shape in the folding surface 52. These triangular partial regions 102, 104 again form a rounded edge region between the front wall 12 and the side wall 28 when the blank 10 is folded.

  Furthermore, the further folding surfaces 54, 56, 58, 58 ′ are also rounded edge regions when the blank 10 is folded, but the corresponding side fold lines 112, 114, 116, 118. It will be appreciated that it is formed by a plurality of crease lines 74, 76, 78, 80 that extend in parallel to each other. Such a configuration of the folding surfaces 54, 56, 58, 58 'is known from the prior art. It will be appreciated that the configuration of the folded and rounded surfaces 54, 56, 58, 58 'is significantly different from the configuration of the folded surfaces 50, 52, respectively.

  Furthermore, it will be appreciated that the crease lines 68, 70, 72 are formed in a straight line and are formed as a continuous straight line between the side fold lines 60, 62, 64, 66. However, other possibilities for the construction of the crease lines 68, 70, 72 are also conceivable.

  Furthermore, the folding surfaces 50, 52, 54, 56, 58, 58 ′ have side walls 26, 28, 30, 32, which contact the respective wall and bottom elements 12, 16, 22, 20 and the blank 10 when folded. It will be appreciated that a rounded fold region is formed between each and the lid sidewalls 34, 36, 38, 40. Further, the corners of the bottom element 14 and the second lid wall 18 are rounded so that these two elements match the shape of the folded surface when the blank 10 is folded.

  Further, the side walls 30 and 32 have adhesive flaps 46 and 48 that are hingedly connected via corresponding folding lines 98 and 100, and the adhesive flaps 46 and 48 are in a state in which the blank 10 is bent (not shown). It will be clear that it is adhered to the inner surface of the bottom element 14. At the end of the side walls 30, 32 opposite the adhesive flaps 46, 48, they are separated from the lid side walls 34, 36 by corresponding cutting lines. Here, the cutting line extends to each starting point of a folding line 86 formed between the rear wall 16 and the first lid wall 22. The adhesive flaps 46, 48 serve to form the bottom structure 90 in cooperation with the bottom element 14 when the blank 10 is folded.

  FIG. 2 is a schematic view of a second embodiment of the blank 10. It will be appreciated that the shape of this second configuration is substantially the same as the first embodiment shown in FIG. Therefore, in the description of the figure, the description of FIG. 1 is referred to. In contrast to the first embodiment, the blank 10 according to the second embodiment has folding surfaces 50, 52 of different configurations. The folding surfaces 50, 52 also form a rounded edge region in the folded state of the blank 10, but first at an angle with respect to the side folding lines 60, 62, 64, 66. It will be appreciated that it has two crease lines 70, 72 that extend within the folding surfaces 50, 52. Here, the crease lines 70 and 72 intersect at points located on the side fold lines 60 and 64. This intersection point is arranged in the central region of the folding surfaces 50 and 52. Due to the arrangement of the crease lines 70 and 72, three partial regions 106, 108, and 110 are generated in the folding surfaces 50 and 52 in this case as well. Here, the partial regions 106, 108, and 110 are formed in a triangular shape. In contrast to the embodiment shown in FIG. 1, further creases 124 are formed in the two partial areas 106, 110. Here, the crease line 124 extends parallel to the side fold lines 60, 62, 64, 66. The configuration of these further creases 124 results in a particularly clear and clean rounded structure. In contrast, the additional partial area 108 has no further creases, so that this embodiment is also cheaper and faster to produce than blanks with known rounded edge areas. can do.

Each of the described blanks 10 for generating a three-dimensional structure and a folding box is typically composed of cardboard, paper, or plastic. Other suitable materials are also contemplated. The blank 10 can be manufactured by punching and / or laser energy. Other suitable manufacturing methods are also conceivable.
