Said cut (1) comprises a first side wall (3), a front wall (4), a second side wall (5), a rear wall (6), and a sidewall strip (20) which are disposed in said order and the free sides of which are connected to tabs (31, 32, 41, 42, 51, 52, 61, 62) that are used for gluing. The walls (3-6) are connected to each other by means of first folding lines (11, 11`, 11``, 11```) that extend transversely across the cut (1) while the tabs (31, 32, 41, 42, 51, 52, 61, 62) are connected to the walls (3-6) by means of second folding lines (12, 12') extending in the longitudinal direction of the cut (1). Two tearing lines (8, 9) extend across the walls (3-6) at a distance from each other. A third folding line (13) extends parallel to the second folding lines (12, 12') across the center of one of the walls (6) while the two tearing lines (8, 9) extend across all other walls (3-5).

Description

Cut for a prismatic container

The invention relates to a blank for a prism-shaped container after erection and closing, which is preferably used to hold cigarette packs, with a front wall, a second side wall, a rear wall and a side wall strip, which are arranged in the order given and on their free sides Connect each flap used for gluing, the walls being connected to the walls by first fold lines running across the cut and the flaps by second fold lines running in the longitudinal direction of the cut, and two tear lines running at a distance from one another across the walls.

Such a blank is known from DE 197 36 730 AI. It serves, for example, to take up cigarette packs as an outer carton 5 or containers and to make them visible after tearing open the tear lines and throwing away the resulting tear strip.

• The object of the invention is to further develop the known blank in such a way that the container can be opened after being torn open and still remains in one piece.

This object is achieved in that a third fold line runs centrally over one of the walls 5 and parallel to the second fold lines, and in that the two tear lines run over all other walls.

A cut line preferably adjoins the third fold line to and also ends at this, so that it does not form a closed curve. In one embodiment, the cutting line has the shape of a hook, in another embodiment that of an "S", as a result of which, after the container produced with the blank has been torn open and opened, a tab is formed on the connecting line between the two halves, which acts as a handle or flag can be used.

Further advantageous refinements of the invention are the subject of the claims.

The invention is explained below with reference to a drawing; show it:

Shape.

Figure 1 shows the simplest form of a first embodiment for a blank 1 for the manufacture of a container. Cardboard or rigid plastic can be used as the material. As a rule, the production will be made of cardboard, with the individual side parts being attached by gluing. The first embodiment for the blank 1 shown in FIG. 1 has the following parts in a continuous sequence from left to right: are each connected via first fold lines 11, 11 ^λ , 11 ", ll ^{λ Λ} : a first side wall 3, a front wall 4, a second side wall 5, a rear wall 6 and a side wall strip 20. All of the walls 3 to 6 mentioned are rectangular The two side walls 3 and 5 are narrower than the front wall 4 and the rear wall 6. The width of the side walls 3 and 5 and the front wall 4 and the rear wall 6 is at the discretion of the person skilled in the art The two side walls 3 and 5 are congruent and the front wall 4 is also congruent with the rear wall 6. To the right edge of the rear wall 6 a * side wall strip 20 closes over the first fold line II. The side wall strip 20 has the shape of a trapezoid and a smaller width than the first side wall 3, in order to more easily fit into the container on the inside Insert side wall 3. The side wall strip 20 is adhered to the first side wall 3 after erecting of the blank 1 in such a manner that the adhesive is applied to ^its' outside, so in Figure 1 of the drawing area. The first side wall 3 closes otherwise on the first fold line 11 to the front wall 4. The second side wall 5 is in turn connected to the north wall 4 via the first fold line 11 and to the rear wall 6 via the further first fold line 11 ^λX . If the blank 1 is thus 5 folded along the first fold lines 11-11 ^{λ λ} and erected to form a container, then a sleeve or a jacket is formed after the side wall strip 20 has been glued to the first side wall 3.

10 On the walls 3 to 6 there are also tabs 31, 32; 41, 42; 51, 52; and 61, 62, which are also connected to the blank 1 via second fold lines 12, 12 ^Λ . The two second fold lines 12, 12 ^Λ run in the longitudinal direction of the blank 1, while the first fold lines

1511-11 ^X at right angles to it and thus across the blank 1.

Specifically, first side wall tabs 31 and 32 adjoin the first side wall 3 at the top and bottom, the north side wall 4 has north side tabs 41, 42, the second side wall 5 has second side wall tabs 51, 52 and the rear wall 6 has rear wall tabs 61 and 62. The shape of the tabs 31, 32; 41, 42; 51, 52; 61 and 62 is freely selectable for the expert; it is only important that they do not interfere with the erection of the blank 1 into a container and 5 also form a decorative cover on the outside. In order to be able to provide this decorative cover, the front wall tabs 41, 42 are rectangular in shape, for which they have the width of the front wall 4 and a height which corresponds to the width of the side walls 3 and 5, respectively. The side wall tabs 31, 32; 0'51, 52 and the rear wall flaps 61, 62 each have the width of their associated walls, but a reduced height compared to the front wall flaps 41, 42 and bevelled side edges so that they are trapezoidal.

5 A third fold line 13 expediently runs centrally over one of the walls 3 to 6 between the two second fold lines 12, 12 ^λ and parallel thereto, which is 11 ^x from a first fold line to the neighboring other first fold line ll ^{λλ is} sufficient. At the left edge of the rear wall 6, which is formed by the first fold line 11 ^{λ Λ} , now at a distance from the third fold line 13 upwards and downwards at attachment points 18, 19 there is a tear line 58, 9, which extends over all other walls 3 to 5 and extend over the side wall strip 20. In an embodiment not shown, the two tear lines 8, 9 can run parallel to one another and form a rectangular strip, the width of which corresponds to the distance between the two attachment points 18, 19

10 corresponds to the first fold line 11 ^{λ Λ} . In the embodiment shown, however, the two tear lines 8, 9 diverge on the second side wall 5 in order to form a widened tear strip 22. The greatest width of the tear strip 22 is determined by the distance between the two

I5 tear lines 8, 9 formed in the front wall 4.

The tear lines 8, 9 run parallel to one another over the front wall 4. Other line shapes are also conceivable, which do not necessarily have to be parallel to one another. In the first 20 side wall 3, the tear lines 8, 9 continue over their entire width, but run again towards one another and end at a tongue 23, the width of which in one embodiment corresponds to the distance between the two attachment points 18, 19; the tongue 23 can have any shape.

25

Although in the exemplary embodiment shown the two tear lines 8, 9 run symmetrically to a center line which is congruent with the third fold line 13, it is clear that this is only an expedient course. It is also suitable for any other, also asymmetrical, course of the two tear lines 8, 9 to form the tear strip 22, provided that this extends only over all walls of the blank except for one.

35 In order to be able to actually tear off the tear strip 22 from the erected bundle after the side wall strip 20 has been glued to the first side wall 3, the tear strips Continue lines 8, 9 between attachment points 18 and 19 * along the first folding line 11 ^VΛ . Furthermore, they must also be provided in the side wall strip 20, namely congruent with the course in the first side wall 3, which is indicated by the reference numerals 8 ^Λ , 9. Tear lines 8 and 9 ^{Λ are also} provided in the side wall strip 20, which end at the first fold line 11 ^Λ and run there from the attachment point 18 ^λ to the attachment point 19 towards one another. 0

The cut 1 is now erected into a bundle in such a way that the side wall strip 20 is first glued to the first side wall 3. Simultaneously or shortly thereafter, the side wall strips 31 and 51 are folded inwards together with the rear wall strips 61 and provided with adhesive on their outside, which is the underside of the sheet with respect to the plane of the drawing. The front wall strip 41 is then folded over the tabs 31, 51, 61 and glued to them.

Now the container would have to be filled with the contents, for example with cigarette packs. Then the side wall flaps 32 and 52 and the rear wall flap 62 are folded up from the plane of the drawing and provided with adhesive on their outside or with respect to the drawing plane on their underside. When the front wall tab 42 has been folded over the tabs 32, 52 and 62 and glued to them, the container is closed.

To open the container, grasp the tongue 23 and tear the tear strip 22 along the tear lines 8, 9; 8, 9 ^Λ from. The inside of the tear strip becomes visible. This can be provided with information, for example about the product in printed form or about an insert which is fixed there but can be removed.

Then the container can be folded back along the third fold line 13, as is indicated in FIG. 3. you also sees that the content, for example cigarette packs 25, then becomes visible. In addition, two sections 24, 24 can be seen which, after the container has been fully opened in the manner shown in FIG. 4, form a carrying handle or a flag. Such a handle * can be prefabricated from thin material, preferably cardboard, and attached to the inside of the blank from FIG. 1 above the third fold line 13.

10 A more elegant method for producing the handle from the blank itself is explained with reference to FIGS. 2A to 2D.

Figure 2A shows a second embodiment for the blank 1 'of the side walls 3 and 5, the front wall 4, the

15 rear wall 6 and the tabs 31, 32; 41, 42; 51, 52; and 61, 62 corresponds to the embodiment according to FIG. 1. The main difference, however, is that in the rear wall 6 ^" a hook-shaped cutting line 14, 14 is arranged symmetrically to the third folding line 13, which at A on the third folding line

2013 starts and also ends at B at this. * With its connecting part 14, it cuts through the third fold line 13, while there is no cut along the third fold line 13. The connecting part is therefore designated by 14 in FIG. 2A. This creates the two sections 24 and 24, which consist of the drawing

25 plane can be bent out upwards and connected or glued to one another and in this state overlap one another in such a way that together they can result in a handle of the form shown in FIG. ^•

Since the vertical folding of the sections 24, 24 ^Λ creates an opening in the rear wall 6, the rear wall 6 is expediently covered by a rear wall strip 2, which in the embodiment shown connects to the free edge of the first side wall 3 via the first fold line n , The 5 rear wall strip 2 thus has the same length and width as the rear wall 6, so that it completely covers it. Since the rear wall strip 2 can be glued to the rear wall 6 and thus the sleeve or the casing ^'is formed, the side wall strip 20 provided in the first embodiment according to FIG. 1 can be omitted. However, it is necessary that 5 the tear lines 8, 9 continue over the entire width of the rear wall strip 2 and in turn end in the tongue 23 used for gripping.

It is clear to the skilled person that, the bonding of the rear wall 6 with blaze rear wall strip 2 takes place in such a way that the adhesive strips are applied on the inside of the rear wall strip 2, ^■ which corresponds with respect to the plane of the upper surface of the sheet. '

15 It is also clear that with this folding the perpendicular to the rear wall 6 sections 24, 24 ^Λ protrude into the interior of the container and only after opening and unfolding the container are directed upwards as in Figure 4, as a handle or as Flag to serve for attaching characters or 0 labels.

If the rear wall strip 2 is dispensed with in the embodiment according to FIG. 2A and the tongue 23 is formed on the converging parts of the tear lines 8, 9, then the blank 1 ^ΛΛ shown in FIG. 2B 5 is ^obtained , in which an opening is provided in the rear wall 6 which can be used as window 24f according to FIG. 6A. The latter is said. Indicate vertical hatching.

A further advantageous embodiment, which is not shown, arises if, starting from a blank according to FIG. 1, the third fold line 13 is designed as a perforation line. After opening the container by removing the tear-open tab 22, the packaging can be set up as shown above 5 by folding along the fold line 13 and separated into two partial containers by breaking the perforation. FIG. 2C shows a blank 1 ^{Λ Λ} similar to that in FIG. 2B, parts corresponding to one another being provided with the same reference symbols. This embodiment leads to a container with a triangular cross section, as shown in FIGS. 5D and 6D. In this embodiment, the first fold lines 11, 11 ^Λ and 11 ^{ΛΛΛ are formed} from a plurality of fold lines which run parallel and at a short distance from one another, so that rounded edges 110 are formed after the container has been erected. In addition, in the case of the cut 1 ^Λ, the front wall tabs 41, 42 are not rectangular, as before, but rather trapezoidal. Furthermore, the rear wall tabs 61 ^Λ , 62 are not designed trapezoidal, but triangular, as can be seen in the drawing. Finally get lost

15 also the tear lines 8, 9 ^X not parallel to one another over the front wall 4 ^Λ , but diverging in order to converge again over the side wall 3 towards the tongue 23. In this embodiment, the front wall 4 ^{Λ is} actually a side wall, so that it has the same width as the side wall 3. in case of a

20 Cross section of the package in the form of an equilateral triangle, of course, the side wall 3, the front wall and the rear wall 6 all have the same width.

Figure 2D shows another blank 1 ^λ for the preparation 5 of a hexagonal packing in FIG 5E bzw.6E. Again, those parts that correspond to the previous embodiments are provided with the same reference numerals. The drawing is understandable in itself. It is clear that the rear wall flaps 61, 62 ^Λ in this embodiment have a hexagonal cross section, while all other flaps 31, 31a, 32, 32a, 41, 42, 51, 51a, 52, 52a have the shape of isosceles trapezoids.

Figure 3 shows the opening of a rectangular container after 5 tearing and removing the tear strip 22 or 22 ^λ according to Figure 2A or 2B. Similarly, the containers produced with the ^' blanks 1, 1 ^{Λ Λ} and i ^{λ Λ} according to Figures 1, 2C and 2D are opened. In the case of a blank 1 according to FIG. 1, the sections 24, 24 ^{Λ are} not part of the rear wall 6, but are attached to it in a manner known per se, for example by gluing.

FIG. 4 shows the fully opened container according to FIG. 3, the cigarette packs 25 having been removed. For this you can see the rear wall 6 with integrated sections 24, 24 ^Λ , which form a flag or a handle when opened.

FIG. 5 shows five different shapes of the container that can be produced with the blank 1 ^{λ Λ} according to the invention, specifically in FIG. 5A with a rectangular cross section, in FIG. 5B with an octagonal cross section, in FIG. 5C with a rectangular cross section with rounded edges, in FIG. 5D with a triangular one Cross section with rounded edges and in Figure 5E with a hexagonal cross section.

Figure 6 shows the five containers of Figure 5 but from the rear, so that one can see the window 24f formed by the right angle inwardly folded portions 24, 24 ^Λ.
