Description

Blank for a cigarette pack

The invention relates to a blank for a cigarette pack.

Numerous blanks for cigarette packs are already known, for example for so-called cap folding boxes, in which a flat blank made of cardboard is provided with fold lines and incisions and is erected into a rectangular block shape in use.

It is an object of the invention to provide a blank for a novel cigarette pack which has a shape deviating from the rectangular cuboid shape with rounded side edges.

To achieve this object, the blank according to claim 1 and a method for its production according to claim 6 are used.

Advantageous embodiments of the invention are the subject of the dependent claims.

In the method according to the invention, the packaging is produced from two blanks, namely an inner part blank and a jacket blank. First, the inner part from the relatively simply shaped inner part blank is placed around a format body, then folded or shaped into an inner part and then glued together, one end of the inner part remaining open in order to remove the format body again in a later step. Preferably, the inner part is pulled off the format body immediately after the gluing and pushed into a format hollow body, so that the inner part can now be filled with its contents, for example with cigarettes. The inner part is then completely closed and pulled out of the format hollow body again. This possibility offers the advantage that the content or the product, which is now in the closed inner part, functions of a format body takes over. Now the very simply shaped jacket blank is placed around the inner part and glued. The preferred method step of removing the inner part from the format body at an early stage and replacing it with the product to be packaged has the advantage that the inner part can already be closed, which is not the case when the format body is used further, and that the packaged product together with the inner part forms a stable format body around which the jacket blank can be formed. Since the method according to the invention requires much less kinking and gluing, the packaging can be manufactured much more quickly. Finally, the required production facilities are also less complicated and therefore cheaper and less prone to failure.

This process is suitable for a variety of different forms of packaging. However, this method is particularly advantageous in the case of packaging with rounded or semicircular long sides. In order to facilitate the production of the curves, the inner part blank and / or the jacket blank can be provided with a plurality of parallel, pre-grooved fold lines on the curve regions. In this way, packaging with different cross-sectional shapes can be produced.

The invention is explained in more detail below on the basis of exemplary embodiments; show it:

Figure 15 is a schematic plan view of an apparatus for producing cigarette boxes.

In the figures, the same parts are provided with the same reference numerals throughout, while an apostrophe (') or a quotation mark (") is added to similar or corresponding parts. The blanks are also shown at about 1: 1 scale.

FIG. 1 shows the inner part 2 of a first embodiment of a blank for a cigarette packet, which is made from left to right from a substantially rectangular strip which initially forms a rear side 14 ', to which a first side section 18' with pre-grooved fold lines 17 connects, which extend across the entire width of the blank. On the first side section 18 'provided with fold lines 17 connects the front side 12 ', which merges into the second side section 16', which, like the first side section 18 ', is provided with pre-grooved fold lines 17 which extend over the entire width of the blank. A second adhesive flap 19 adjoins the second side section 16 'and does not extend over the entire width of the blank.

A U-shaped collar cutout 21 with rounded corners 22 is provided at the upper edge of the front side 12 ′, which serves to facilitate access to the cigarettes. At the lower edge of the front side 12 'there is a second adhesive flap 23, which approximately has the shape of a not yet mentioned soil 6 ha. The bottom 6 has the basic shape of a rectangle, which adjoins the lower edge of the back 14 'and whose length corresponds to the width of the back 14'. A semicircular surface is formed on each of the two short sides of the rectangle, so that the base 6 has an approximately oval shape.

On the other side of the blank opposite the base 6, a cover 8 adjoins the rear side 14 ′, the shape of which is congruent with the shape of the base 6. At a distance from the edge 28 of the base 8 adjacent to the rear side 14 ', a fold line 31 runs parallel to the edge 28 of the cover 8 and ends at an incision 30 which runs at right angles to the fold line 31 up to the upper edge of the blank. As a result, a cap section 34 is formed, through which the lid 8 can be opened to the rear in the finished cigarette pack.

A third adhesive flap 32 adjoins the front edge 29 of the cover 8 opposite the rear edge 28 and is later glued to the front part of a jacket 4. The third adhesive flap 32 is also followed by an insertion flap 33 which serves to lock the packaging which has been broken open again. Figure 2 shows the jacket 4, which later envelops the glued inner part 2 and is only visible except for the bottom 6 and lid 8 in the finished packaging according to Figure 11. For this purpose, the jacket 4 is rectangular except for a fourth adhesive tab 40, which adjoins a short side of the jacket 4, for example the left side section 18. A curved opening edge 10 runs over the upper half of the jacket 4, which is in the fully extended part is designed as a section line 10 'and in the part indicated by dashed lines as a hinge line 10 ". The hinge line 10" thus runs over the rear side 14 of the casing 4, while the section line 10' of the opening edge 10 extends over the front side 12 and the subsequent side sections 16 and 18 .

Figure 3 shows the jacket 4 'of a second embodiment, which corresponds essentially to the jacket 4 of Figure 2. The difference is that in the area of the front 12 the bottom 6 and the top 8 are formed on the bottom. Furthermore, a fifth adhesive tab 42 is formed on top of the back 14, which is approximately congruent with the lid 8.

Figure 4 shows the inner part 2 ', which together with the jacket 4' forms the cigarette pack shown in Figure 11. The inner part 2 'has essentially the shape of the front 12' from FIG. 1 with the adjoining side sections 16 'and 18' which are each provided with the fold lines 17. In addition, the second adhesive flap 23 for the inside of the base 8 connects to the front 12 ′ at the bottom, while the collar cutout 21 with the rounded corners 22 is provided at the top.

It is pointed out that the adhesive tab 23 for the base 8 can also be arranged on the jacket 4 'according to FIG. 3, which would correspond to an embodiment according to FIG. 5. In this case, the inner part 2 'of FIG. 4 would have an approximately rectangular shape with a straight lower edge, while in the upper edge the collar cutout 21 with the rounded corners 22 remains.

FIG. 5 shows a further embodiment for the jacket 4 ″, essentially in accordance with FIG. 3, but with a third adhesive tab 23 for the bottom 6 attached to the bottom 14 at the bottom, while the fifth adhesive tab 42 for the bottom 14 on the top edge of the back Lid 8 connects.

The jacket 4 "is expediently used with an inner part which essentially consists of a collar 25. The collar 25 in turn has the collar cutout 21 with rounded corners 22, as can be seen in the area of the front side 12 'of FIG However, collar 25 does not extend over the entire height of the blank, but has a height reduced by approximately 2/3 and a lower edge 27, the shape of which roughly corresponds to the shape of the collar cutout 21. Wings 26 adjoin the collar cutout 21 on the right and left, which are again provided with pre-grooved fold lines 17 as in the embodiment according to Figure 1. The pre-grooved fold lines 17 extend over the entire height of the collar 25.

Figure 7 shows a fourth embodiment of the invention, in which the jacket 4 '' 'corresponds essentially to the jacket 4' of Figure 3, but with the modification that the bottom 6 is not part of the jacket 4 '' ', but to the inner part 2 "shown in FIG. 8 connects.

FIG. 8 shows the inner part 2 ″, which can expediently be used in conjunction with the jacket 4 ″ ″ for producing a cigarette pack according to FIG. 11. The inner part 2 ″ has essentially the shape of the inner part 2 according to the embodiment from FIG. 1, only the cover 8 with the adhesive tab 32, the insertion tab 33 and the cap section 34 is omitted.

Figure 9 shows the inner part 2 '''of a fifth embodiment of a blank for a cigarette pack, in which again same parts as in the first embodiment shown in Figure 1 are provided with the same reference numerals. The two inner parts 2 and 2 '''differ on the one hand in that the fifth adhesive tab 42' instead of the cover 8 connects to the back 14 'and on the other hand in that in the collar cutout 21 a tongue 24 is seated which is in contact with the collar cutout 21st hangs at a few points 44 and can thus be broken away from the collar cutout 21 when the package is opened. At the upper end of the tongue 24 there is a first tab 35, the length of which corresponds approximately to the width of the collar cutout 21 and the width of which corresponds to approximately half the width of the cover 8 or the fifth adhesive tab 42 '.

On the opposite side, at the point at which the second adhesive tab 23 hangs in the embodiment according to FIG. 1, there is a second tab 36, the length of which is approximately the length of the base 6 and the width of which is approximately half Width of the bottom 6 corresponds. Furthermore, the second adhesive tab 23 'hangs at the lower end of the rear side 14'.

During assembly, the inner part 2 '' 'is first bent around a format body until the first adhesive tab 19 can be glued to the inside of the back 14', so that a closed jacket is formed. The first and second flaps 35 and 36 are then folded inwards, while the second and fifth adhesive flaps 23 'and 42' are then folded over the first and second flaps 35 and 36 and glued to them.

It is pointed out that this means only the folding of the inner part to explain the structure of the cap box produced therewith, while in the above explanation no consideration was initially given to the insertion of the cigarette block. This will be explained later.

In the side sections 16 'and 18' there are also a C-shaped each in the vicinity of the upper edge of the inner part 2 '''and thus at the edge which will later be adjacent to the cover 8 Notch 38 is provided with the openings of the C-shapes facing each other. When the inner part 2 '''is closed, this results in two lugs projecting outwards in the opposite direction, by means of which the cap of the pack is kept closed.

FIG. 10 shows the jacket 4 "" belonging to the inner part 2 "" of the fifth embodiment, which differs from the jacket 4 according to FIG. 2 only in that at the front wall 12 of the jacket 4 "" bottom 6 and top cover 8 connect. In addition, a third tab 37 connects to the rear wall 14 at the top and a fourth tab 39 at the bottom. The third and fourth tabs 37 and 39 each have the same length as the width of the front wall 14, while their width is approximately half the width of the bottom 6 and corresponds to the cover 8.

In addition, in the fifth embodiment, four triangular adhesive tongues 41 each adjoin the side sections 16 and 18 at the top and bottom, the tips of which point outward and which are also provided for bonding to the base 6 and the lid 8, respectively. Due to the triangular shape of the adhesive tongues 41, it is possible that the side sections 16 and 18 can be bent semicircular.

It is clear that the various elements can be combined with one another in another way so that a cigarette packet according to FIG. 11 can always be produced, even if the arrangement of the individual wall sections is chosen differently.

FIG. 12 shows a sequence of method steps for producing the inner part 2 for a cigarette pack, which has an approximately oval-shaped cross section. For this purpose, in a first step A, a flat inner blank 2 is sucked out of a blank magazine with the aid of negative pressure. Then, in a second step B, a format body 1 is placed over this blank 2. Then, in step C, the inner part rear and the inner part side part, which are made of the inner part Blank 2 are formed, erected.

Subsequently, the first adhesive flap of the inner part side part is glued and formed in step D around the format body 1. The back of the inner part blank 2 is then also shaped around the format body 1, pressed onto the glued tab of the inner part and thus glued to the inner part. Then one of the bottom covers of the inner part blank 2, which were previously also referred to as adhesive tabs, is glued and folded around the format body 1. Then the other bottom cover of the inner part blank 2 is folded onto the already glued bottom cover and glued to it.

In step E, the glued inner part 2, which is open on its head side, is finally pulled off the format body 1.

FIG. 13 shows a sequence of process steps, in which the filling of the previously produced inner part 2 is shown. For this purpose, in step F, the inner part 2, which is open on its head side, is pushed into a format hollow body 3.

In step G, a cigarette block 5 wrapped with, for example, aluminum foil is inserted into the hollow body of the format

3 located inner part 2 pushed.

In step H, the cover flap is folded on the head side of the inner part 2 and inserted into the format hollow body 3.

In step J, the closed inner part 2 filled with cigarettes is finally pushed out of the format hollow body 3.

FIGS. 14A and 14B show a sequence of process steps in which the application of a jacket blank

4 is shown around the filled inner part 2 up to the ready-made cigarette pack. First, in step K, the flat jacket blank 4 is sucked out of a blank magazine with the aid of negative pressure, then it is glued over the entire surface and then in step L it is brought over a format pocket 7. The filled inner part 2, which now has the function of a format body, is then placed on the jacket blank 4 in step M and pressed into the format pocket 7 with the aid of a stamp 9 (step N), as a result of which the side sections 16, 18 and the rear side 14 of the jacket blank 4, through which the back of the cigarette pack is later formed, are bent upwards and the side section 18 is then pressed around the inner part 2 with the help of the format cheek 11. At the same time, the stamp 9 is moved back to the starting position (step 0).

The rear part of the jacket blank 4 is formed in step P by the format cheek 11 '. The stamp 9 then presses against the rear part from above in order to glue it to the inner part 2.

In step Q, the format cheeks 11 and 11 'are opened again and the stamp 9 moves up into the basic position. The ready-made cigarette pack 13 is then pushed out of the format pocket 7.

FIG. 15 shows a schematic plan view of a device for producing the cigarette packs 13. First, the inner part blanks 2 held in a blanking magazine at the head end of the device are transported by means of negative pressure into associated positions on a first turntable 15. There, the inner part blanks 2 are processed into inner parts in accordance with method steps A to E. These inner parts are then transferred to a second turntable 20, on which the inner parts are filled with cigarettes in accordance with method steps F to J. The cigarette blocks 5 wrapped in aluminum foil, for example, are fed via a conveyor belt. The filled inner parts are then transferred to a third rotary table 43, on which process steps K to Q are carried out. The finished cigarette packs 13 are then removed from the device via a conveyor belt.
