Description

Blank and a three-dimensional structure made therefrom

The present invention relates to a blank for producing a three-dimensional structure of paper, cardboard or plastic, in particular a packing or the like, comprising at least one folding face for forming a rounded edge area of the three- wherein the folding surface is bounded by two lateral folding lines extending parallel to one another. The present invention also relates to a three-dimensional structure of paper, cardboard or plastic, a folding box for storing articles, in particular a folding box of cardboard, paper, and the like, and a method of manufacturing the blank.

Such blanks, three-dimensional structures and folding boxes are very well known. In particular, these blank or three-dimensional structures and folding boxes are each a flip-pack, which represents a wide range of packaging materials for cigarettes and the like. Thus, the references [DE 43 11 568 A1, EP 2 141 090 A1, DE 101 06 547 A1, US 6 276 600 B1 and DE 600 28 078 T2] are in the prismatic form along the longitudinal axis, Lt; RTI ID = 0.0 > hingedly < / RTI > From the reference [WO 2012/123189 A1], a folding box having a rounded edge area is known. A rounded edge area is achieved by cutting a plurality of these areas. A plurality of discrete surfaces are produced by cutting, which can be folded into a rounded edge area as a whole. However, these known packaging materials have a disadvantage in that a plurality of cuts are required to form a rounded edge region. The preparation of the punch tool is time consuming and expensive. Production by laser energy is also relatively time consuming and energy intensive due to the multiple required cutting lines.

Accordingly, it is an object of the present invention to provide a method and apparatus for producing a three-dimensional structure of paper, cardboard or plastic, a common blank, a corresponding three-dimensional structure, paper, A corresponding folding box of cardboard or plastic and a method of producing the mentioned 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 serve to accomplish this object. Advantageous constructions of the invention with its convenient development are specified in the respective subclaims and the advantageous construction of the blanks is not limited to the three-dimensional structure according to the invention and the folding box according to the invention as well as the advantageous configuration of the method according to the invention Respectively, and vice versa.

A first aspect of the present invention is a blank for producing a three-dimensional structure of paper, paperboard or plastic, in particular a packaging material, etc., comprising at least one folding line for forming a rounded edge region of the three- Wherein the folding surfaces are bordered by two lateral fold lines extending parallel to one another. According to the present invention, at least one creasing line extending obliquely to the lateral fold line is formed in the fold line. Surprisingly, it has been found that the rounded edge area of the three-dimensional structure can already be produced by these corrugated lines in the corresponding folded state of the blank. Thus, the time required to prepare the punching or creasing tool to construct the crease line can be significantly reduced. In addition, considerable less laser energy has to be consumed compared to known blanks in order to produce corrugated lines according to the invention and thereby to constitute, for example, the rounded edge areas of packaging materials, in particular tobacco packaging materials. For example, the known blanks have 5 to 7 bent lines parallel to the folding line that laterally bounds the folding surface. The number of corrugated lines can be considerably reduced by the configuration of the corrugated wire according to the present invention in the folding plane. Thus, in addition to corresponding cost savings, production rates can also be increased by 25% to 75% compared to conventional blank. Here, the corrugated lines for manufacturing the rounded edge region are so-called "half cuts ", which are line-shaped concave portions that do not completely penetrate the cutting line or the blank or blank substrate as a cut completely penetrating the substrate of the blank or blank. " The pleats can also be constructed on the inside and / or outside of the blank, or in the folded state, i.e. on the folding box thus induced. Here, the pleats and / or lateral fold lines are formed, for example, on the inside or outside of the blank. However, it is possible to form a particularly memorable pattern on the folding box in the folded state of the blank by allowing different fold lines and / or lateral fold lines to be constructed on different sides, i.e. on the front and / Can also be considered.

In another advantageous construction of the blank according to the invention, the lateral fold lines and crease lines are produced by laser energy and / or punching. By the exclusive or at least partial use of the laser energy to manufacture the blank, the corresponding element of the blank can be manufactured very accurately and quickly. In addition, configuration changes of individual elements can be performed particularly simply and quickly without the need to create a new punching or embossing tool. Further, according to the present invention, there is an advantage that a less powerful or slower laser can be used to produce the pleats according to the present invention, resulting in a significant cost advantage in the manufacture of the blank. Significantly higher manufacturing and production rates still occur, since significantly fewer corrugated lines are required than known blanks to form the rounded edge area of the three-dimensional structure produced from the blank.

In another advantageous configuration of the blank according to the present invention, the corrugation lines formed in the folding surface comprise a first end and / or an edge region of the folding surface and a second end of the folding surface opposite the first end and / And extends between the edge regions. However, it is also possible for the pleats to extend between the first end and / or the edge region of the folding surface and the second end and / or the edge region opposite the first end and / or edge region. It is also possible that the corrugation lines are likely to be formed on the first end of the folding surface and / or on the outside of the edge region and on the folding surface outside the second end and / or edge region of the folding surface opposite the first end and / have. Due to the configuration of the pleats according to the invention, a very different extension of the pleats in the fold plane can be conceived for the final configuration of the rounded edge area of the three-dimensional structure. Accordingly, corresponding design specifications can be easily satisfied.

In another advantageous configuration of the blank according to the invention, at least one end of the pleat intersects or is adjacent to the corresponding lateral fold line of the folding surface. In this case, the configuration of the corrugated lines in the folding plane can also meet the corresponding production and / or design specifications.

In another advantageous construction of the blank according to the invention, the folding surface is divided into at least two partial regions by at least one corrugation line, and the partial regions are each formed by a triangle. By the triangular shape of the partial area, a round formed particularly advantageously in the folded state of the blank occurs. Here, additional pleat lines can be formed in at least one of the partial regions, so that other, especially finer, round structures can be formed in these regions.

In another advantageous configuration of the blank according to the present invention, the corrugation lines are formed in a straight line, a bent line, a wavy line, a meandering line, a stepped line, or a combination thereof. Further, the crease lines may be formed as continuous or discontinuous crease lines between the lateral crease lines. Thereby, a plurality of design requirements can be satisfied again advantageously.

A second aspect of the invention relates to a three-dimensional structure of paper, paperboard or plastic made by folding and / or attaching blank as described above. The construction and advantageousness of the three-dimensional structure thus produced is also due to the construction and advantages of the blank described in accordance with the invention in accordance with the first aspect of the invention described above. Here, the three-dimensional structure may be composed of a packaging material, in particular, a packaging material for storing cigarettes.

A third aspect of the invention is a folding box for storing articles, in particular a cardboard, paper or the like, comprising at least one front wall, at least one rear wall, and at least one first And a second sidewall; And a plurality of folding surfaces for forming a bottom edge structure for closing the bottom surface of the folding box and a rounded edge area for each one of the folding box. Here, at least one folding surface is bounded by a lateral folding line in accordance with the present invention, and at least one folding line extending obliquely to the lateral folding line is formed in the folding surface. This folding box is considerably cheaper compared to known folding boxes with rounded edge areas because each folding box must have at least one or at least one fold line formed on the corresponding folding face to form the rounded edge area of the folding box . There are significant time and cost advantages in using laser energy for mechanical production and wrinkle production by punching, creasing or embossing.

In another advantageous configuration of the folding box according to the invention, at least one end of the pleats intersects or is adjacent to a corresponding lateral fold line of the folding surface. Further, the crease lines may be formed as continuous or discontinuous crease lines between the lateral crease lines. With this configuration of the fold lines in the folding plane, the rounded edge area of the folding box can be manufactured simply and inexpensively. In addition, very different design requirements for this area of the folding box can be easily met. Also, the pleats can be configured on the inside and / or outside of the folding box. Here, all pleats and / or lateral fold lines are formed, for example, on the inside or outside of the folding box. However, it is also contemplated that different pleats and / or side fold lines may be configured on different sides, i.e., the inner and / or rear side of the folding box, thereby forming a particularly memorable pattern on the folding box.

Further features and advantages of the present invention will be apparent from the description of the first and second aspects of the present invention, and advantageous configurations of the first and second aspects of the present invention are regarded as advantageous configurations of the third aspect of the present invention, The opposite is true.

A fourth aspect of the present invention relates to a method of manufacturing a blank as described above. Here, the outer contour of the blank and / or the contour of the fold line and / or the inner contour of the blank and / or the cut line and / or crease line can be produced by laser energy according to the present invention. By the exclusive or at least partial use of the laser energy to manufacture the blank, the corresponding element of the blank can be manufactured very accurately and quickly. In addition, configuration changes of individual elements can be performed particularly simply and quickly without the need to create a new punching or embossing tool.

Other advantages, features and details of the present invention will become apparent from the following description of the two embodiments as well as the drawings. It is to be understood that the features and combinations of features mentioned above in the description, as well as combinations of features and features mentioned below in the description of the drawings and / or shown in the drawings, may be combined in any combination, Can be used.

1 is a schematic view of a blank according to the invention according to a first embodiment;
2 is a schematic view of a blank according to the invention according to a second embodiment;

Figure 1 shows a schematic view of a blank 10 for producing a three-dimensional structure of cardboard. Here, the three-dimensional structure is a packaging material, particularly a folding box. Here, the blank is placed on the wall and floor elements 12, 14, 16, 26, 28, 30, 32 connected through the folding surfaces 50, 52, 54, 56 in the folded state of the blank 10 (not shown) And a fold line 82, 84 for forming at least one container-shaped receiving area. The rear wall 16 is also connected to the first lid wall 22 via the bent line 86 to form a closed cap 92 in the folded state of the blank 10, The lid wall 22 is connected to the second lid wall 18 via the bent line 88 and the second lid wall 18 is connected to the third lid wall 20 via the third bent line 90 . The first lid wall 22 is also connected to the lid side walls 34, 36 via the folding surfaces 54, 56. The third lid wall 20 is connected to additional lid side walls 38, 40 through folding edges 58, 58 '. The adhesive flaps 46 and 48 are also placed on the cover sidewalls 34 and 36 through bent lines 94 and 96 which are in contact with and adhered to the inside of the second lid wall 18 in the folded state of the blank 10 . The third lid wall 20 further has a bent line 92 'on the side opposite the second lid wall 18 and is connected thereto via a further adhesive flap 24. [

It can be seen here that the folding planes 50, 52 are bounded by the lateral fold lines 60, 62, 64, 66. The two pleats 70, 72 are formed in the folding surface 50, each extending obliquely to the lateral fold lines 60, 62. Here, the corrugation line 70 is formed by the first end and / or the edge region 120 of the folding surface 50 and the second end and / or the edge region (i.e., the first edge and / or the edge region 120) 122). ≪ / RTI > This region is located on the lateral fold line 60. Here, the corrugated lines 70 intersect or are adjacent to the fold lines 60. In contrast, the second corrugated line 72 formed on the folded surface 50 has an intersection with the second corrugated line 60 of the first corrugated line 70 from the second end and / or edge region 122 And is adjacent to the corresponding end of the first pleat line 70. As shown in Fig. With this configuration of the corrugated lines 70 and 72, three partial regions 106, 108 and 110 are generated in the folded surface 50. [ The partial regions are each formed as a triangle, and a rounded edge region of the folded blank 10 is formed. Also, at the folding surface 52 adjacent to the front wall 12, only one corrugated line 68 is formed. Which extends between the opposing second end and / or edge region 122 of the first end of the folding surface 52 and / or the edge region 120 and the folding surface 52. With this configuration, the partial surfaces 102 and 104 formed by two triangles also occur in the folded surface 52. [ By these triangular partial regions 102 and 104, a rounded edge region between the front wall 12 and the side wall 28 again occurs in the folded state of the blank 10.

It is also contemplated that additional folding surfaces 54,56, 58 and 58'which cause a round edge area in the folded state of the blank 10 extend parallel to the corresponding lateral fold lines 112,114, It is conceivable that a plurality of corrugated lines 74, 76, 78, and 80 are formed. This configuration of the folding surfaces 54, 56, 58, 58 'is known from the prior art. It can be seen that the configurations of the folding and round surfaces 54, 56, 58, 58 'are significantly different from the configurations of the folding surfaces 50, 52, respectively.

It can also be seen that the corrugated lines 68, 70 and 72 are formed as straight and continuous straight lines between the lateral fold lines 60, 62, 64 and 66. However, other possibilities of the configuration of the corrugated lines 68, 70 and 72 are also conceivable.

The folding surfaces 50,52,54,56,58 and 58'are not only the side walls 26,28,30,32 adjacent to the wall and bottom elements 12,16,22,20 but also the side walls A folded area is formed between the cover side walls 34, 36, 38, 40, respectively. The edges of the bottom element 14 and the second lid wall 18 are also rounded so that the shape of these two elements is adapted to the shape of the folded surface in the folded state of the blank 10.

The side walls 30 and 32 also have adhesive flaps 46 and 48 that are hingedly coupled through corresponding curved lines 98 and 100 and the adhesive flaps 46 and 48 are in the folded state of the blank 10 Not shown) to the inner surface of the bottom element. At the ends of the sidewalls 30 and 32 opposite the adhesive flaps 46 and 48 they are separated from the cover sidewalls 34 and 36 via corresponding cutting lines. Here, the cutting line extends to the starting point of each of the bent lines 86 formed between the rear wall 16 and the first lid wall 22. The adhesive flaps 46 and 48 serve to form the bottom structure 90 in cooperation with the bottom element 14 in the folded state of the blank 10.

Figure 2 shows a schematic view of a second embodiment of the blank 10. This second configuration is almost the same as the first embodiment shown in Fig. 1, so that it can be seen that the description of Fig. 1 is referred to in the description of the drawings. In contrast to the first embodiment, the blank 10 according to the second embodiment has different configurations of the folding surfaces 50, The folding surfaces 50 and 52 that re-form the rounded edge area in the folded state of the blank 10 first extend within the oblique folding faces 50 and 52 to the lateral fold lines 60, 62, 64 and 66 And has two corrugated lines 70, 72. Here, the corrugated lines 70, 72 intersect at points located on the lateral fold lines 60, 64. This intersection point is constituted in the central region of the folding surfaces 50, 52. With this configuration of the corrugated lines 70 and 72, the three partial regions 106, 108, and 110 again occur within the folding planes 50 and 52. Here, the partial regions 106, 108, and 110 are formed as triangles. Unlike the embodiment shown in FIG. 1, additional corrugations 124 are formed in the two partial regions 106, 110. Here, the corrugated lines 124 extend parallel to the lateral fold lines 60, 62, 64, 66. The construction of such an additional corrugation line 124 causes a particularly clear and precise round structure. In contrast, the additional subarea 108 does not have additional corrugations, so this embodiment can also be made cheaper and quicker compared to known blanks having rounded edge areas.

The blank 10 described for producing a three-dimensional structure and a folding box, respectively, is generally made of cardboard, paper or plastic. Other suitable materials may also be contemplated. The blank 10 may be manufactured by punching and / or laser energy. Other suitable manufacturing methods are also contemplated.
