Abstract

The invention relates to a (cigarette) pack made of sealing film, which has an opening structure that can be used multiple times in the area of an inner front wall (26). By using a closure label (30) that can be used multiple times and is fixed by adhesive bonding, a removal opening in the pack film can be opened. The closure label (30) has lateral stabilization strips (32) which, as original parts of the closure label (30), are separated therefrom during the first use of the closure label (30). The stabilization strips (32) effect shaping reinforcement in the area of the inner front wall (26) Furthermore, (lateral) sealing seams – side seams (15, 16) – are arranged in a special way in order to ensure the box-like contour of the pack.

Description

Cigarette pack and method of making the same description

The invention relates to a cigarette packet having the features of the preamble of claim 1. Furthermore, the invention is concerned with methods for producing such packages. Cigarette packs made of a sealing film or with an inner packing made of sealing film are known in a variety of designs. The foil or inner pack is provided with stabilizing organs arranged inside the same - inner collar - or with an outer (partial) sheath made of appropriate packaging material (thin cardboard). The inner package has a removal opening which extends at least in the region of an end wall and which is provided with a reusable closure tab or a closure label. This is attached by means of permanent adhesive to the package and is fixed in Schlielistellung with an adhesive edge on a region surrounding the removal opening of the inner pack. In a known package (DE 10 2010 027 175 A1), the closure label extends (in one piece) over the full width of the inner wrapper.

The bag-shaped package of thermally sealable film preferably has two opposing closure seams and preferably a transverse or tubular seam, all seams in the design as a fin seam, so that the layers of the film are connected to each other by means of heat and pressure without affecting the contents of the package can. The closure seams are in the region of the front wall and bottom wall or in the region of upright side walls of the inner pack attached (DE 10 2011 119 344 A1).

CONFIRMATION COPY The invention is concerned with measures to provide or provide a substantially parallelepiped, precisely designed package with improved dimensional stability for the entire period of use by the consumer.

To solve this problem, the package according to the invention is characterized by the features of claim 1.

The measures according to the invention lead to an exact, dimensionally stable design of the inner pack made of foil in the face region. The extensions or stabilizing strips extend as lateral strips of material across the end wall into the adjacent inner front wall and the inner rear wall of the pack. When the closure label is opened for the first time, it is partially or completely detached from the extensions due to the dividing line. Preferably, the stabilizing strips are shortened or reset in the region of the (inner) front wall, so that only a short leg bears against the front wall of the pack.

The pack or inner pack is preferably arranged in an outer pack in the form of a folding box or hinge lid pack with a conventional collar. The stabilizing strips, in particular the shortened strips are at least partially in the region of webs, which are formed by a collar front wall of the outer package. Another measure for creating an exact, stable, cuboidal inner packing relates to sealing seams in the design as a fin seam. Preferably, these are - in the middle - arranged in the region of narrow inner side walls of the inner pack. The - initially due to two consecutively mounted - relatively wide sealing or fin seams are inventively reduced in terms of effective width, by separating a material or suture strip and / or by multilayer folding and applying to the inner side wall. A further improvement of the production of the package is the ventilation of the interior. The foil blank of the inner pack is provided with vents, preferably in the execution of U-shaped punches. These are arranged so that after attaching a first sealed seam by appropriate pressure air is largely removed from the interior of the pack. The second seal closes the vents so that no air can flow back into them inside the pack. Finally, measures according to the invention are made which bring about an exact formation of the inner end wall, namely corresponding, pack edges associated score lines of the film in conjunction with lines of weakness or perforation lines of the closure label along the packing edges of the inner end wall.

Further features of the package according to the invention and measures for producing the same are explained in more detail below with reference to the drawings. 1 shows a (cigarette) pack with a folding box as an outer pack in the open position, in a perspective view, FIG. 2 shows the pack according to FIG. 1 with (additionally) opened

Aromatic and moisture-proof (cigarette) packages are provided with an inner package 10 which consists of a dense (multi-layered) thermally sealable film. The inner pack 10 serves to receive a cigarette group 11, that is to say a number of cigarettes 12 formed or arranged in rows. The cigarette group 11 is surrounded on all sides by a foil blank 13 (FIG. 4). Closure seams create a hermetically sealed inner package 10. In the present embodiment, the film blank 13 is an elongated, rectangular portion of a continuous film web 14 with lateral sealing seams, ie side seams 15, 16 in the form of a fin seam. The side seams 15, 16 are in the range of opposing, narrow, upright inner side walls 17, 18 of the inner package 10. Another, transverse seam - transverse seam 19, also in the form of a fin seam - is located in the region of an inner rear wall 20. The transverse seam 19 is produced in the production of the inner package 10 in a first sealing step as a continuous tube seam of the tubular film web 14. The opposite side of the inner pack 10, namely an inner front wall 21, is presently free of sealing seams.

Within the substantially cuboidal inner pack 10, a support member is arranged, namely an inner collar 22. This forms a collar front wall or collar top wall 23, which faces the inner front wall 21 of the inner pack 10 and bears against this. On the collar top wall 23 lateral support tabs 24 are arranged. Furthermore, folding flaps 25 are provided to form a transverse to the collar top wall 23 directed collar bottom. The folded inner collar 22 is formed as a tray and extends substantially over the full height of the inner pack 10 and the cigarette group 11. A top or front side of the inner collar 22 is open. Furthermore, a recess 41 is formed at the upper edge of the inner collar 22, which facilitates the removal of the cigarettes 12. In cross section, the inner collar 22 extends or extend preferably the support tabs 24 over the full width (and height) of the inner side walls 17, 18 (Fig. 17 to Fig. 19).

The inner pack 10 is provided with a special, multiple-use opening and Schliedstruktur. The foil or the foil blank 13 has a removal opening 27 for the cigarettes 12 in the region of an inner end wall 26. This extends over the full depth of the inner end wall 26 and in an adjacent region of the inner front wall 21 on the one hand and the inner rear wall 20 on the other. In the region of the removal opening 27 there is an opening tab 28 as part of the film blank 13. The opening tab 28 is bounded by a U-shaped weakening line or perforation line 29. Along this, the opening tab 28 is cut out during the first opening of the inner package 10 from the connection with the film blank 13. The area of the removal opening 27 and the opening tab 28 is covered by an actuating tab or a closure label 30. The preferably consisting of plastic film or adhesive paper closure label 30 is provided over the entire surface with a (permanent) adhesive, which is used to open the inner pack 10 by detecting a Pull tab 31 of the inner pack 10 (partially) can be deducted with the opening tab 28 and release the removal opening 27 (Fig. 2). In order to close the removal opening 27, the closure label 30 is moved back into the starting position, with restoration of the adhesive connection with regions of the inner packaging 10 surrounding the removal opening 27.

The closure label 30 is formed in a special way, namely with preferably on both sides arranged widenings or attachment pieces, which act as stabilizing strip 32. These are lateral parts of the closure label 30, preferably of the same material. The (two) stabilizing strips 32 are delimited by a central actuating part of the closure label 30 by dividing lines, in the present case by perforation lines 33. The stabilizing strips 32 are preferably provided with adhesive over the entire surface, ie they are adhesive to the film blank 13 or the inner packaging 10 by applying the closure label 30 connected. Upon first actuation of the closure label 30, this is separated from the stabilizing strip 32 due to the perforation lines 33, so that during use of the package, so even with repeated opening and closing of the inner pack 10, the stabilizing strips 32 constantly, permanently in connection with the inner pack 10 remain ,

The stabilizing strips 32 are effective in the frontal region of the inner pack 10. The inner end wall 26 is covered at its full width or depth at the edge by the stabilizing strips 32. A (shorter) leg 34 extends in the region of the inner front wall 21. The shortened leg 34 is with respect to the contour of the complete closure label 30 is formed by a lateral cutout 62, so that the narrower peelable part of the closure label 30 remains free of lateral stabilization strips 32 in an area which is first actuated upon opening. The perforation lines 33 form a continuation of the free edge of the first actuated part of the closure label 30. Longer legs 35 of the stabilizing strips 32 extend over the full dimension of the closure label 30 into the region of the inner rear wall 20. The perforation lines 33 extend into the However, the inner rear wall 20 associated region of the closure label 30, but can advantageously at a distance from the free edge ends (Fig. 21, Fig. 23).

In the transverse direction, the stabilizing pieces 32 are preferably aligned exactly with the dimension of the inner pack 10. Free, lateral edges 36 of the strips 32 run along fold edges of the inner pack, in particular over the full length of an edge section in the region of the inner end wall 26. This creates a stable, precise shape of the inner pack 10 in the region of the opening structure. If, as shown in the exemplary embodiment, the closure label 30 is permanently fixed to the inner rear wall 20 in the area of the inner rear wall 20 with an end piece (FIG. 16), the stabilizing strips 32 also remain in connection with the closure label 30 in this area In the region of the inner front wall 21, this protrudes beyond the stabilizing strips 32 or is set back relative to the contour of the closure label 30, so that it can be better grasped for actuation.

Further measures relate to the dimensional stability of the inner pack 10 at least in the region of the inner end wall 26. Transverse packing edges 37 for the front and rear boundary of the inner end wall 26 are pre-stamped by treatment of material layers. The film of the inner package 10 is provided with preferably continuous, so over the full width of the inner blank 13 extending stamping lines 38, 39. These are creasing lines which are attached as continuous embossing in the area of the film web 14 (FIG. 3) by means of a corresponding embossing or creasing tool. The stamping lines 38, 39 are parallel to each other and at a distance according to the width of the inner end wall 26. In the folding of the inner blank 13 so exact packing edges 37 of the inner end wall 26 arise.

This effect is increased by measures in the area of the closure label 30, by creating lines along the embossing lines 38, 39. In the present case, the closure label 30 is provided with lines of weakness or perforation 40 which are congruent with the embossing lines 38, 39 and present extend in the area of the stabilizing strips 32. The opening process of the closure label 30 is not impaired by the perforation lines 40, because a continuous structure of the closure label 30 is created by the opening tab 28.

The film blanks 13 are separated from a prepared film web 14, after wrapping the cigarette block of cigarette group 11 and inner collar 22 (FIG. 12). The film web 14 has the exact position attached closure labels 30 which are adhesively attached over the entire surface of the film web 14, in the region of the previously prepared perforation lines 29 for the opening tab 28. The prefabricated closure labels 30 are preferably with the perforation lines 33 to delineate the stabilizing strips 32 provided. If the closure label 30 is also provided with the perforation lines 40 for marking the packaging edges 37, these are expediently also already attached during the production of the closure labels 30.

In the manufacture of the inner packs 10 with a cigarette block as the content, the film web 14 is folded around it in a tubular manner during the transport of successive groups of cigarettes 11, in particular with an inner collar resting against the cigarettes. The longitudinal edges are connected by a sealed seam (fin seam) with each other to form a film tube. The tube seam appears as a transverse seam 19 on each inner pack 10. The cigarette groups 11, which are transported within the film tube at a distance from one another, are separated from the tubular film web 14 (FIG. 12) to form the side seams 15, 16 (transverse to the film web), with the simultaneous production of a first sealed seam formed as a fin seam (FIG. 8, Fig. 9), ie a partial seam 42. This is located at a greater distance from the (cuboid) package contents. In the area between the successive groups of cigarettes (double-width) sealing members 49, 50 are used, which produce the part seams 42 on successive inner packs 10 and at the same time by means of separating knife 51 an inner pack 10 separated from the subsequent or subsequent film tube.

In order to create an accurately shaped inner package 10, a second sealing step is subsequently performed (FIG. 13) by sealing jaws 43, 44, which act in close proximity to the inner side wall 17, 18. By means of this, a second partial seam 45 is produced parallel to the first, outer or peripheral partial seam 42, so that the form of the inner lateral walls 17, 18 apparent from FIG. 10 is created. The now double-wide sealed seam, consisting of the part seams 42, 45, can be reduced in terms of the effective length. According to FIGS. 10 and 14, it is provided that a partial area of the laterally directed strip of material with the seams 42, 45 is separated by means of separating knife 46, in particular in the embodiment as rotating cutter disks, in conjunction with a fixed counter knife 47, namely in each case an edge strip 48. What remains is a side seam 15, 16, which is located directly on the inner side wall 17, 18 and is reduced in width, which is folded over against the inner side wall 17, 18 and fixed thereto (FIGS. 15, 16). The width of the side seams 15, 16 thus formed corresponds approximately to half the width of the inner side wall 17, 18. This results in a finished inner pack having an exactly cuboid contour (FIGS. 15, 16).

Different embodiments of completely finished (inner) packs 10 are shown in FIGS. 17 to 19. FIG. 17 is a cross section of FIG Mafigabe of Fig. 8 to Fig. 11 produced package. An alternative is shown in FIG. The effective width of the material strip created after the application of two (partial) seams 42, 45 can be reduced by appropriate folding. A U-fold 52 is formed so that the contours of the inner side walls 17, 18 are not exceeded with a free leg. According to Fig. 18, the U-fold 52 is directed upward - to the front of the inner pack 10 -. The alternative with the U-fold 52 facing towards the rear is shown in FIG. 19. The pieces of material formed by the fold 52 are expediently pressed against the inner side walls 17, 18 and connected to them, in particular by (light) sealing.

The cross sections according to FIGS. 17 to 19 also show a special embodiment of the inner collar 22. Collar edges 53 formed between the collar top wall 23 and the lateral support tabs 24 are designed as bevelled edges - octagonal. This special design of the inner collar 22 can be used in outer packages 54 with at least frontal beveled edges 59 (FIG. 7), but also in classic round edge packages.

Also for improving the shape of the (inner) packing 10 measures are provided for the venting of the package, so for the removal of excess air from cavities within the package. The film blanks 13 or the film web 14 are or is provided with ventilation openings 60, in the present case with two ventilation openings 60 arranged on opposite sides, in the region of the inner side walls 17, 18. Via the ventilation openings 60, pressure is applied to the inner package 10 Air dissipated. In particular, this measure is performed after attaching the first partial seam 42 (FIG. 8, FIG. 9). The ventilation openings 60 are designed as U-shaped punches with tongues directed toward the side or to the sealing seams 42, 45, preferably on the inner rear wall 20. The relative position of the ventilation openings 60 is selected such that they are closed by attaching the second partial seam 45 becomes (Fig. 10, Fig. 11). When separating the edge strip 48, at least part of the ventilation openings 60 or the U-punching is also separated due to appropriate positioning (FIG. 11). Parts of the ventilation openings 60 may lie in the region of the second partial seam 45 and are closed by them (FIG. 11).

In the present embodiment, the venting of the inner pack is effected or supported by a further air opening 61. This is created by interrupting the first sealing seam 42 (FIGS. 8 to 11). The air can escape here between the layers of the film blank 13 in the region of the sealed seam 42. Conveniently, the punched vent opening 60 is located adjacent the air vent 61 so that effective venting can take place. By separating the edge strip 48 and the air port 61 is eliminated.

The described inner pack 10 is preferably arranged in an outer pack 54 of thin cardboard. In the present embodiment (Fig. 1, Fig. 2), the outer package 54 is formed as a folding box with a lower box part 55 and pivotally connected thereto via a rear line joint cover 56. Within the folding box or the box part 55 is a conventional collar 57th attached to a recess 58 adjacent to the opening structure of the inner package 10. The recess 58 is formed so that when the lid 56 of the outer package 54, a free access to the closure label 30 and the grip tab 31 is ensured. Front-side packing edges 59 of the box part 55 and the lid 56 are formed as beveled edges, analogous to the collar edges 53. In the present structure of the inner package 10, the side seams 15, 16 are in the region of the side walls of the outer package 54 and sidewalls of the collar 57.

A packing which is particularly advantageous with regard to the design and arrangement of the closure label 30 is shown in FIGS. 20 to 23. The outer package 54 is provided with obliquely directed packing edges 59 at the front and at the back (octagonal packing). The arranged in the outer package 54 collar 57 is, for example in the embodiment of FIG. 6, also provided with bevelled edges 63, in coordination with the pack edges 59 of the folding box. Furthermore, also the inner collar 22 provided in this embodiment with obliquely directed collar edges 53. These are expediently also used when the outer package 54 is formed as a round edge packing (folding box with rounded packing edges).

The closure label 30 is adapted to the particular shape of the outer package 54 with regard to the contour (FIG. 23). The lateral stabilizing strips 32 are provided in the region of the end wall 26 with a (trapezoidal) projection 64. This corresponds in dimension and contour of the lateral region of the end wall 26 so that it is completely and positively covered by the closure label 30 with respect to the inclined edges 53, 59, 63.

Another special feature is that the stabilizing strips 32 or their legs 34 are at least partially covered in the region of the inner front wall 21 by the collar 57 of the outer package 54. Through the recess 58 in the region of a collar front wall 65 arise lateral collar webs 66 which partially overlap the stabilizing strip 32 and the leg 34 and thus fix it in its position. The separable by the perforation lines 33 central body of the closure label 30 is (completely) in the region of the recess 58, is therefore not detected by the collar webs 66.
