Abstract

A method for the production of a form of packaging especially for gifts, advertising items and CDs comprising a cut-out of paperboard or some other flexible springy material that is cut on the flat with a base segment (115) side segments (119, 120, 121) and/or flaps (125, 126, 127) and which has cut or stamped into it slits (122, 123, 124) and parallel folds (116, 117, 118) and/or fold lines (128, 129, 130) where one slit is cut into each side segment parallel to neither the parallel fold nor the fold line in that segment. The cut-out is folded along the parallel and/or stamped fold lines and the tip of each flap in turn is inserted into the slit in the following side segment from outside. The resulting, folded cut-out then forms a stable and rigid package without the need for adhesives.

Description

Packaging, cutting therefor and processes for their production

The invention relates to a method for producing a packaging, in particular for gifts, promotional items and CDs, from a cardboard blank or a blank made of flexible, spring-elastic material, the blank and a packaging from this blank.

Cardboard packaging for compact discs (CDs) are known. Similar to book shipping packages, these packages are made from a cardboard blank. The cardboard packaging is already folded and glued by the manufacturer except for two or only one flap arranged on the outside. After inserting a CD, the tab or tabs are then inserted from the outside to close the packaging below the CD. In these outer packaging, the CDs can either be packed as a gift or can also be sent by post. The recipient usually destroys the packaging when opening, but the tabs tear off very soon even when the opening is opened very carefully.

The invention is based on the object of proposing a new method for producing a packaging, in particular for gifts, promotional items and CDs, from a cardboard blank or blank made of a flexible, resilient material and a new packaging and blank, the method, packaging and blanking open up the possibility of reuse after first use, so the packaging can be unfolded without damage and the folded packaging ensures stability and strength in itself without the use of adhesives.

This object is achieved in a method by a blank made of flexible, resilient material, in which an essentially flat blank is punched out or cut out with a base element, side parts and / or tab elements, incisions and parallel folds and / or folds, one in each case Incision made within the area of each of the side panels

ORIGINAL DOCUMENTS see, not parallel to the folds or parallel folds of this side part, that the blank is folded along the parallel folds and / or folds and all around the front area of each preceding tab element or side part is inserted into the cut of the subsequent side part from the outside, and that thus folded blank forms a stable and firm packaging without the use of adhesives.

A blank according to the invention is characterized in that a base element, side parts and / or large tab elements are formed with incisions, each tab element being connected by a fold to a side part or by a parallel fold to the base element so that the respective on The fold or parallel fold of the adjacent side length of the flap element corresponds to the respective side length of the side part or of the base element.

A packaging according to the invention is characterized, for example, by the fact that the packaging is pyramid-shaped or flat, that the side walls of a pyramid-shaped packaging consist at least partially or entirely of a double layer of material, that the side walls of a flat packaging are the areas between the two folds of a parallel fold, whereby no tab elements are provided, but the side parts with the incisions inside the side parts are inserted into each other all the way round, thereby forming the top of the flat packaging, and that the bottom surface of the packaging is rectangular, square, polygonal or triangular.

This not only creates a reusable packaging, but also an interesting wrapping which, in the first alternative, due to its pyramidal shape, does not immediately reveal from the outside that, for example, a CD or other flat object is contained in the packaging. In addition, no other fillers, such as wood wool, styrofoam chips or the like, which are undesirable for reasons of weight, cost and environmental protection, are required within the packaging to protect their contents. It is particularly advantageous that the packaging according to the invention can be gripped easily and without glue by a seller in a shop and folded up very quickly. After folding, neither an inside CD nor any other gift can be seen from the outside. The outer shape of the packaging is aesthetically pleasing as a gift packaging. As a promotional packaging, it remains in the customer's memory as a particularly striking appearance. In addition to advertising printing, packaging made of transparent material can develop its advertising appeal in combination with the internal product.

Due to the fact that the blank is only folded up when necessary and thus three-dimensional, the packaging can be stacked beforehand as carton blanks or blanks effortlessly and in a space-saving manner. The manufacturing costs are also low, since only the manufacturing steps of punching out and pre-punching the later folds, but not possible gluing, are required.

The possibility of frequent reuse after first use has also proven to be particularly advantageous.

For storage, the packaging can be unfolded again and stored again as a flat blank to save space. If the used packaging is finally thrown away one day, it is uncomplicated and can be composted or recycled without residues without residue, using cardboard blanks and other environmentally friendly materials. The blanks can also be made from recycled material.

Another pyramid-shaped packaging is known from DE 71 39 632 U1, but it is far from being as stable or even reusable as that according to the invention. Her floor element is square. Three of the side parts adjoining it by folds are essentially triangular. The fourth side part has a trapezoidal and a square partial area with a tab. The side part opposite this fourth side part has folds along its two edges with adjoining four trapezoidal tabs. Incisions are provided along the two folds, each assigned to one of the tabs. The two triangular side parts provided adjacent to the last side part each have two attached tabs on their outer edges facing this side part. The tabs are provided in the edge area in a hook-shaped, round, projecting manner with undercuts. As a result, they hold firmly within the incisions in the respective fold of the third side part.

Exactly these hook-shaped fastenings tear off automatically when such a package is opened. It is therefore not reusable.

The cut in DE 71 39 632 U1 is mirror-symmetrical. Only one side of the triangle or side of the finished packaging is provided with the tabs with incisions in the fold, whereas the other two adjoining side parts are provided on only one outer edge with the small projecting tabs attached. The tabs are therefore only inserted symmetrically from the other two side parts into the one middle intermediate side part provided with the incisions.

In the method according to the invention, large tab elements, which essentially correspond to the size of the side parts, are inserted into incisions within the side parts. These incisions are in no way provided, as in the prior art according to DE 71 39 632 U1, on the edge of the side parts, but in the middle of the surface of these side parts. The incisions are also not provided in the line of a fold or a folded edge, but rather removed from such a fold, not parallel to it. According to the invention, the incisions are always provided at an angle to such a fold.

The packaging known from EP 0 279 485 A1 is also constructed with mirror symmetry and is in some cases of a highly complicated structure; to the Small angular noses are again put together and tear off when the packaging is opened. In addition, due to the complicated structure of the blank, rapid assembly, for example “in the way” in the sales area of a CD store, is impossible. Despite the hooks, packaging according to EP 0 279 485 A1 is not particularly stable: if it is dropped onto a table from a height of a few cm, it opens automatically.

In contrast to the mirror-symmetrical design according to DE 71 39 632 U1 or EP 0 279 485 A1, a rotationally symmetrical arrangement of the side parts and tab elements around the base element is always selected according to the invention in all embodiments. When the blank according to the invention is folded into the packaging according to the invention, the tab element of a previous side part is therefore inserted into the incision within the subsequent side part with respect to this direction of rotation in each case in a selected direction of rotation.

Tests carried out by the applicant have shown that a practical variant of the packaging according to the invention, made from standard cardboard and standing on a table as a pyramid, can withstand a vertical load of up to 5 kg. This is an enormous value for packaging of this type made of cardboard. The reason for this stability of the packaging according to the invention is the ring composite, which is created by inserting the large tab elements into the incisions within the subsequent side parts in each direction from the outside.

On the other hand, when unfolding, the ring assembly can be broken up without any problems and without barbs, since the rotationally symmetrical arrangement simply breaks apart when one of the tabs is loosely inserted without undercut.

A tearing off of the tab elements, especially when opening, as is possible with the small projecting tabs, for example in the case of packaging according to DE 71 39 632 U1, can also be due to the transportation of the Packaging with content does not happen because a lower edge of the large tab elements according to the invention is supported on the fold of the side part, in the incision of which they are inserted, to form the base element. There is in each case a double layer of material through the stacking of the tab elements and side parts in the case of pyramidal packaging according to the invention.

Known flat packagings, for example according to US Pat. No. 1,794,153 or US Pat. No. 2,562,261, also have hook-shaped projections in order to hold one another and to avoid an automatic unintentional opening. Practically unavoidable, these hooks tear off when the packaging is opened, reuse is not possible. Another problem with the packs from US Pat. No. 1,794,153 and US Pat. No. 2,502,261 is also the formation of rosettes in the central region of the top of the pack. These rosettes tend to shear during transport because they open up a "third level" of the entire complex. A stacking of the filled packs, which is often desired for flat packs, is also not possible because of these rosettes.

The flat blank according to the invention is made from one piece. It has a base element and on all sides of the base element side parts and / or tab elements. These are folded out of the plane along all the folds. The tab elements and / or side parts overlap. They can be fastened to one another by pushing together corner areas of the tab elements into incisions within the adjacent side parts or tab elements. The incisions are advantageously provided in the overlap area of the side parts or the tab elements.

After the corner regions of the tab elements and the incisions have been inserted into one another, the tab elements lie firmly in the incisions due to static friction of the adjacent layers of rough material, for example cardboard, and the edge friction of the edges of the tab elements within the incisions. The tab elements are supported in themselves closed incisions with their edges. Preferably, one edge of a side part of a flat packaging with a triangular base element, after being folded, lies against the subsequent outer fold of the parallel fold. It optimally has half the length of a triangular side of the side part. With a greater length, more material is consumed than is necessary, with a shorter length, the durability or stability decreases, although the function is still performed.

In order to pull the tab elements out of the incisions again, they can advantageously be bent slightly. This requires manual access. This ensures the stability and inherently firm connection of the packaging. The use of adhesives is not necessary, since the packaging acquires complete strength when the tab elements are inserted into the incisions. Reopening is possible at any time without the risk of destroying the packaging or the (cardboard) cut. As with the pyramid-shaped packaging, the incisions in the flat packaging according to the invention are provided within the surface of the side parts. "Inside" here does not mean in the edge area, but preferably at a distance from it, at least approximately 2 cm from the edge or fold.

The packaging is preferably pyramidal or flat. The floor elements are therefore advantageously rectangular, square, pentagonal or triangular. They can also be polygonal. The side parts are preferably isosceles triangles and form the sides in a pyramid-shaped packaging. The tab elements either have the same shape as the side parts or they are flattened at the tips and / or obliquely trapezoidal. Regardless of this, the packaging can have different sizes, colors and shapes.

The side walls of a pyramid-shaped package according to the invention are preferably at least partially or entirely formed from a double layer of material which is produced by folding. The side walls of a flat packaging according to the invention are preferably formed by the areas between the two folds of a parallel fold, no tab elements being provided, but rather the side parts with the incisions inside the side parts are inserted into one another all the way round and thereby form the top of the flat packaging.

To explain the invention in more detail, several exemplary embodiments of packaging are described below with reference to the drawings.

These show in:

1 shows a plan view of a first embodiment of a packaging according to the invention,

2 shows a perspective side view of the folded packaging according to FIG. 1,

3 shows a plan view of a second embodiment of a packaging according to the invention,

4 shows a perspective view of the folded packaging according to FIG. 3,

5 shows a plan view of a third embodiment of a packaging according to the invention,

7 shows a plan view of a fourth embodiment of a packaging according to the invention, 8 is a perspective view of the folded packaging according to FIG. 7,

9 is a plan view of a fifth embodiment of a packaging according to the invention,

10 is a perspective view of the folded package according to FIG. 9,

11 is a plan view of a sixth embodiment of a packaging according to the invention and

12 is a perspective view of the folded packaging according to FIG. 11.

1 shows a plan view of a first embodiment of a packaging according to the invention in the form of a blank 1. The blank 1 has a square base element 2 and four side elements 3, 4, 5, 6. The four side elements 3, 4, 5, 6 are each arranged on one side of the base element. They are in one piece with the base element and separated from it by a fold 7, 8, 9, 10. The side elements essentially have the shape of an isosceles triangle in connection with an oblique trapezoid. Triangle and trapezoid are separated by folds 11, 12, 13, 14. The isosceles triangle created by a fold forms the respective side part 15, 16, 17, 18 of the packaging after folding the blank 1. The tab elements 19, 20, 21, 22, each separated from the triangular side parts by the folds 11, 12, 13, 14, have in principle the same shape as the side parts. The difference is that the front tips of the triangles of the tab elements are separated. This makes it easier to insert the tab elements into the incisions. The front edges 23, 24, 25, 26 of the tab elements run parallel to the respective folds 11, 12, 13, 14. The folds are thus, as it were, the lines of symmetry for the side elements 3, 4, 5, 6, if one of the separated tips which ignores tab elements. As a result, the angle ß between an outer Edge 32 and the fold 14 between the tab element 22 and the side part 18 are equal to the upper acute angle of the isosceles triangle of the side part 18. Likewise, the angle between the other outer edge 33 of the tab element 22 and the fold 14 is equal to one of the lower angles cc of the isosceles triangle of the side part 18.

The centers of the folds between a respective side element and bottom element and within the side element between the side part and the tab element are connected to one another by cuts 27, 28, 29, 30. The front edges 23, 24, 25, 26 of the tab elements 19, 20, 21, 22 are inserted into these incisions 27, 28, 29, 30 when the carton blank is folded for packaging.

After folding, the outer edges of the isosceles triangles of the side parts 15, 16, 17, 18 lie within the folds 1 1, 12, 13, 14. The inclination of the triangular side parts 15, 16, 17, 18 with respect to the base element 2 can one by the size of the side parts 15, 16, 17, 18 and the other by the height of the triangle.

FIG. 2 shows the already folded carton blank or blank according to FIG. 1 in a perspective view. To fold the blank 1, the side elements 3, 4, 5, 6 are first folded out along the folds 7, 8, 9, 10 from the image plane. The flap elements 19, 20, 21, 22 are then folded from the side parts 15, 16, 17, 18 along the folds 11, 12, 13, 14 to the respectively adjacent side part. The front edges 23, 24, 25, 26 are then successively inserted from the outside into the incisions 28, 29, 30, 27 of the adjacent side parts. In Figure 2, the tab element 21 is shown with its front edge 25 inserted into the incision 30 in the side part 18 in dashed lines. An arrow 31 indicates that the tab element 20 is to be inserted with its front edge 24 into the incision 29 from the outside of the side part 17. After all the tab elements and incisions have been plugged into one another, a pyramid-shaped packaging with a square base element, that is to say a tetrahedron, is produced from the blank according to FIG. 1. Gift items, groceries, promotional items or the like can be inserted into this packaging before sealing. Since no adhesive is used when assembling, cardboard, cardboard or food-safe cardboard or a similar flexible, foldable material can be used for cutting. It is also possible to use plastic for cutting. For example, this packaging is very well suited as a gift packaging for storing and giving away chocolates, candies or the like. But also perfumes can be packaged very decoratively, especially if a colorful or decorative colored material is used for the cardboard cutting or cutting.

The arrangement of the incisions 27, 28, 29, 30 has proven to be particularly decorative. These are each provided such that a small triangle is formed in the large triangle of the side parts 15, 16, 17, 18 after the tab elements have been inserted into the incisions. This creates a further spatial effect, since the material usually protrudes a little in the area of the tab elements inserted into the incisions. Depending on the incidence of light, this area results in a darker color due to the opening of the incisions. This makes the packaging look more interesting.

Instead of straight incisions, these can also be curved or provided in writing. This emphasizes the three-dimensional effect. The provision of a written form of the incisions is particularly suitable for advertising purposes, but also for congratulations. In the case of promotional items, the name of the producer or of the product can be provided in writing or with printing.

FIG. 3 shows a top view of a second embodiment of a packaging according to the invention from a cardboard blank or blank 1. The base element 2 is in contrast to that shown in Figure 1 pentagonal. A triangular side part 35, 36, 37, 38, 39 with a tab element 40, 41, 42, 43, 44 attached to it is arranged on each side of this pentagon of the base element 34. In contrast to the tab elements in FIG. 1, the tab elements 41 to 44 are not arranged on the left, but on the right respective triangular side of the side parts 35 to 39 in the plan view of the cardboard blank. The choice of the shape of the tab elements is determined according to the same criteria as in FIGS. 1 and 2, that is to say the correspondence with regard to the basic shape with the side parts. The tab elements are obliquely trapezoidal.

The incisions 45, 46, 47, 48, 49 are provided within the triangular side parts 35, 36, 37, 38, 39. They connect the respective centers between the folds 50, 51, 52, 53, 54 between each side part and the base element and the folds 55, 56, 57, 58, 59 between the triangular side part and its integrally attached tab element.

The upper tips of the side parts meet after folding the blank in the center of the pentagonal floor element 34 at a predetermined height above this center. This is shown in FIG. 4 in a perspective view. After the carton blank has been folded together, a pyramid is again formed which, in this second embodiment, has five side faces.

To fold the cardboard blank according to FIG. 3 into a pyramid-shaped packaging according to FIG. 4, the side parts are first folded upwards along the folds to the base element 34. The flap elements are then placed over the adjacent side parts and folded along the folds between the side part and the flap element. To close the packaging, the individual tab elements are then pushed into the respective incisions in the adjacent side parts, as illustrated by the arrow in FIG. 4. The tab element 44 is inserted with its front edge 64 into the incision 48 in the side part 38. After the entire packaging has been closed, the tab elements are again placed on the side parts. The plug connections hold to one another due to the static friction between the individual layers of the tab element and the side part and due to the edge friction of the tab element edges within the incisions. Both for inserting and especially for pulling the tab elements out of the incisions, the tab elements must be slightly bent outwards. This ensures that the plug connections do not come loose after filling with the contents of the packaging and that they can fall out of the packaging unintentionally.

FIG. 5 shows a third embodiment of a packaging according to the invention from a cardboard blank 1. Similar to FIG. 1, a square floor element 65 is provided. The bottom element 65 has parallel folds 70, 71, 72, 73 on all four sides, ie two folds running parallel to each other. Cantilever corner elements 66, 67, 68, 69 are formed in the corners. The corner elements are square. They have a height or width such as the distance between the two folds or parallel folds 70 to 73 running parallel to one another. The cantilevered corner elements serve as a rigid corner connection after folding the cardboard blank. In order to enable the folding, the projecting corner elements 66, 67, 68, 69 are separated on one side from the adjacent parallel fold. This is indicated in Figure 5 by the dashed arrows.

Cantilevered corner elements 66, 67, 68, 69 are thus provided between each two adjacent parallel folds 70, 71, 72, 73 in the overlap area of the parallel folds, which are separated from the other parallel fold towards one parallel fold and when the packaging is folded up inside stiffen the base of the packaging formed by the parallel folds in the corners and additionally secure internal objects against falling out of the packaging.

In contrast to the cardboard blank shown in FIG. 1, the tab elements 82, 83, 84, 85 shown in FIG. 5 have no front edges but a tip. So they are congruent to the triangular side parts 78, 79, 80, 81.

FIG. 6 shows a perspective view of the folded pyramid-shaped packaging from the cardboard blank according to FIG. 5. The cardboard blank is first folded along the parallel folds 70, 71, 72, 73. The flap elements 82, 83, 84, 85 are then folded along the folds 74, 75, 76, 77 to the adjacent side parts 78, 79, 80, 81. Before the tab elements are inserted with their tips into the incisions 86, 87, 88, 89 of the respective adjacent side parts 78, 79, 80, 81, the projecting corner elements 66, 67, 68, 69 become on the respective inner side of the parallel folds 70, 71 , 72, 73 folded against. This is indicated by an arrow in FIG. 6.

FIG. 7 shows a fourth embodiment of a packaging according to the invention from a blank 1. The blank 1 has a rectangular base element 90. Parallel folds 91, 92, 93, 94 are arranged on all four sides of the base element 90. In contrast to the blank according to FIG. 5, no overhanging corner elements are provided in the blank according to FIG. 7 in the four corners between the parallel folds 91, 92, 93, 94. After the carton blank has been folded up, the end edges of the parallel folds lie against one another without overlapping, cantilevered corner elements. The cantilevered corner elements prove to be particularly advantageous when the contents of the packaging are sprinkled. Otherwise, they can also be omitted.

Tab elements 95, 96, 97, 98 are provided directly after the four parallel folds 91, 92, 93, 94. In contrast to the blanks according to the previous figures, the packaging according to FIG. 7 is essentially flat after folding. Therefore, the side parts are omitted. Instead of this, the material areas provided between the two parallel folds or parallel folds 91, 92, 93, 94 are each provided as side parts. In the top view, the tab elements 95, 96, 97, 98 each have an edge length corresponding to half the width of an adjacent parallel fold on the right side. These edges 99, 100, 101, 102 are aligned with the first fold of the parallel folds directly attached to the base element 90. After the blank has been folded up, it lies above this first fold at a height determined by the distance between the two folds of a parallel fold.

The respective edges 103, 104, 105, 106 opposite the straight edges run obliquely towards them. In principle, the edges 103, 104, 105, 106 run in the direction of the diagonal to the bottom element 90. The tab elements 95, 96, 97, 98 correspond to the diagonally divided bottom element 90. For better insertion of the tab elements into incisions 107 provided within the adjacent tab elements , 108, 109, 1 10, however, the front tips are separated. As a result, the tab elements have front oblique edges 1 1 1, 1 12, 1 13, 1 14. These oblique edges 111, 112, 113, 114 have an angle of slightly more than 90 ° to the other edges 103, 104, 105, 106. The incisions 107, 108, 109, 1 10 are just arranged so that the front ends of the tab elements 95, 96, 97, 98 can hold well in them, that is to say they have optimal edge friction. The arrangement of the incisions can preferably be determined and optimized on the basis of the shape, size and dimensions of the tab elements with the aid of a computer.

The folded carton blank according to FIG. 7 is shown in FIG. To fold the parallel folds 91, 92, 93, 94 are first folded up out of the plane.

The tips of the tab elements 95, 96, 97, 98 are then inserted from above into the incisions 107, 108, 109, 110 provided within the adjacent tab element. This is indicated by the arrow shown in Figure 8. After folding, a rosette with a tiny opening in the middle is formed in the middle of the upper side of the flat packaging corresponding to the base element 90, consisting of the tab elements 95, 96, 97, 98 folded over one another. The flat packaging is also very aesthetically designed. In contrast to the prior art according to US Pat. No. 2,562,261, this rosette does not open up a third level with the disadvantages described above. The opening in the middle can also be omitted. The tab elements then meet directly.

FIG. 9 shows a plan view of a fifth embodiment of a packaging according to the invention from a cardboard blank 1. The cardboard blank 1 has a triangular base element 115 in FIG. Similar to FIG. 5, 15 parallel folds 1 16, 1 17, 1 18, 1 19 are arranged on all sides of the base element. As already shown in FIG. 7, however, no cantilever elements are provided at the corners between the parallel folds. After folding, the end edges of the parallel folds 1 16, 117, 1 18, 1 19 directly abut each other.

Exactly mirror images of the floor element are followed by triangular side parts 119, 120, 121 on all three sides of the size of the floor element 115. The side parts have incisions 122, 123, 124. The incisions connect the centers of the folds between the base element and the side part and the side part and the tab element. They are arranged parallel to one side of the triangle. The folds 128, 129, 130 provided between the triangular side parts and tab elements 125, 126, 127 form the center line for the mirror image of the side parts on the tab elements. This means that tab elements, side parts and bottom element each have essentially the same dimensions. All of them are preferably formed from equilateral triangles.

FIG. 10 shows the carton blank according to FIG. 9 in the folded state. After folding, the side parts 119, 120, 121 form the sides of a triangular pyramid. The tab elements 125, 126, 127 are in turn from the outside into the incisions 122, 123, 124 of the inserted adjacent side part. This is symbolized by the arrow in FIG. 10.

Due to the parallel folds 1 16, 1 17, 1 18, the pyramid rests on a base which connects it to the floor element 1 15 and into which a flat object can be fitted.

FIG. 11 shows a plan view of a sixth embodiment of a packaging according to the invention from a cardboard blank 1. The cardboard blank has an essentially triangular base element 131. As already in FIG. 9, parallel folds 132, 133, 134 are also arranged in FIG. 11 on all three sides of the triangular base element 131. As in FIG. 7, 131 tab elements 135, 136, 137 are arranged on all three sides of the triangular base element following the parallel folds 132, 133, 134. The tab elements 135, 136, 137 each have two edges that meet at a point. The respective first edge 138, 139, 140 lies against the respectively adjacent outer fold of the parallel fold and has a greater length than half of this triangle side. The respective second edge 141, 142, 143 connects the triangle corner opposite the first edge to the end of the first edge 138, 139, 140. The second edges therefore do not form the perpendicular to the triangular surface of the base element 131.

Starting from the respective outer fold of the parallel folds 132, 133, 134, incisions 144, 145, 146 run parallel to the second edges 141, 142, 143. The incisions have a length such that the tips of the tab elements 135, 136, 137 can be inserted so far that the tab elements lie flat against each other after folding.

The tab elements can taper to a point as shown in FIG. 11, but may also be rounded or flattened as shown in FIG.

A further incision 147 is provided in one tab element 137. Starting from the second edge 143 of the tab element 137, it is provided parallel to the first edge 140. Meet in an imaginary line the notch 146 provided in the surface of the tab element 137 with the notch 147 provided on the second edge 143. However, they end so far apart that tearing that connects the two notches does not occur at this point. The further incision proves to be particularly advantageous in the case of shipping packages, since it increases the stability of the packaging. The incision 147 can otherwise be omitted if the packaging is not to be shipped.

FIG. 12 shows the folded packaging from the cardboard blank according to FIG. 11 in a perspective view. After folding, an essentially flat packaging is produced which has a very decorative effect on its top side, that is to say on the viewing side, due to the interlocking tab elements and incisions.

For folding, the tab elements 135, 136, 137 are first tilted upwards along the parallel folds 132, 133, 134. Then the tab element 135 is inserted into the incision 146, the tab element 137 into the incision 145. At the same time, the tab element 136 is inserted into the incision 147. The tab element 136 is then pushed into the incision 144 for the final closing. This is illustrated by the three arrows in FIG. 12.

The tab elements can have lateral incisions in the region of their front ends, parallel to the incisions into which they are inserted. The incisions within the tab elements are then provided to be somewhat shorter than the width of the front end of the tab elements. The lateral incisions then cause the front ends of the tab elements to engage behind the incisions and hold there. This makes opening the packaging considerably more difficult. Such packaging is particularly suitable for mailing.

The cardboard blanks or blanks and packaging shown in the previous figures can be provided in different sizes, shapes and colors. The blanks can be offered as a sales unit in various sizes and / or shapes and / or colors in the trade. Cuts of the same shape with different sizes are preferably provided as an assortment or as a sales unit. The incisions within the side parts or the tab elements can either be provided parallel to an edge of the side part or tab element or obliquely within them. As described, they can be arranged centrally within the side parts or tab elements or in another position, for example close to an edge. The tab element inserted into the incision should only be able to hold in this.

The blank is made of a flexible, foldable, spring-elastic material that ensures static friction when the blank is joined. Cardboard is preferred, as well as cardboard coated or laminated with plastic, solid paper, thin plastic, thin metal or mixed materials made from these materials.

In addition to cardboard, plastic, metal and mixed materials, transparent variants can also be provided as materials for the cutting. These are particularly suitable as advertising packaging. The internal product works in combination with the packaging. In addition, all types of imprints and also embossments can be provided on the packaging. Otherwise, the blank can be single-colored, multi-colored, or can be perforated or reflective.
