Abstract

The cap box type package has a flat container (11) made of base wall, container walls, namely side walls (12) and transverse walls (14), for receiving a group of elongated cigarettes, particularly cigarillos in an inner wrapper. The inner wrapper is made of foil or paper under formation of a block with cigarettes that are oriented parallel to the base wall of the container. An elastically deformable or compressible lifting element is arranged between cigarette block and base wall of the container. An independent claim is also included for a device for manufacturing or filling cap box with a cigarette block and a lifting element.

Description

The invention relates to a pack of the type cap box with the features of the preamble of claim 1. Furthermore, the invention relates to methods and apparatus for producing such cap boxes.

Capsule boxes are known worldwide as one of possible packaging forms for cigarettes, cigarillos or the like. The flat package contents, in particular a group of cigarettes or cigarillos with an envelope of an inner film, lie flat on a bottom wall of the container, the cigarettes are therefore directed parallel to the bottom wall.

For facilitated removal of the package contents, it is known to arrange a tab within the cap box through which the contents of the package - in particular a cigarette block - is brought into a raised inclination when the lid is opened ( EP 1 399 365 B1 ). The tab is fixed to the underside of the cigarette block and connected to a container facing the region of the lid, with the result that a lid facing the region of the tab is pulled out when opening the lid from the container with entrainment of the cigarette block.

Such a trained cap box with a removal aid for the contents of the package is complicated to manufacture, through the complex positioning and fixing the lever ashes.

The invention has for its object to provide an improved cap box with a removal aid for the contents of the package, which has a simple structure and can be produced on efficient packaging machines.

To solve this problem, the cap box according to the invention with the features of the characterizing part of claim 1 is formed.

According to the invention, an elastically compressible lifting member is thus arranged in the container of the cap box below the cigarette block, which preferably consists of a folded blank, which has an elastically deformable lifting part due to appropriate folding and the material property. This is compressed with closed cap box through the (cigarette) block and fixed under tension between the block and the bottom wall of the container. When opening the lid of the (cigarette) block is raised due to the relaxation of the lifting part, in particular in an inclined position.

The lifting member consists of a simple, in particular rectangular or strip-shaped blank made of (thin) cardboard, plastic or a multilayer composite material which can permanently generate tension by folding. In the simplest embodiment, the blank is folded in the transverse direction of the cap box or the cigarettes, such that a leg acts as an elastic lifting part, which rests against the inside or bottom of the (cigarette) block. In the closed position, the leg rests against a base leg. With the lid open, the block is moved to an inclined position, preferably such that the raised removal side of the block faces the lid.

The cap boxes with elastic lifting member is particularly advantageous used when the (cigarette) block is formed as a sealing block with a cigarette group the aroma and moisture-tight surrounding film, which preferably has a reusable opening tab.

In the manufacture or filling of a cap box designed according to the invention, the prefabricated packing is transported along a preferably rectilinear packing web, in particular by a pocket conveyor. In the area of a first station, the cap box is opened. Subsequently, the lifting member is fed transversely to the transport direction, folded and positioned in the container of the cap box. The folded lifting member is fixed by support means. In a subsequent station, the cigarette block is inserted into the container while compressing the lifting member.

It is about the formation of flat packaging containers for cigarettes 10 or other elongated smoking products, which lie flat due to the formation of the package, preferably in a double row, on a bottom wall. This is especially true for the cap shaft shown as the preferred application.

This type of package usually has a (lower) container 11, which is rectangular or square according to the format of the package contents. The container 11 consists of a bottom wall 25 and around running web-like walls, namely side walls 12, 13 and transverse walls 14, 15. The container 11 is closed by a lid 16 which is formed in a similar manner as the container 11. The lid 16 is in the region of a (rear) transverse wall 15 of the container 11 with this via a joint 17, in particular a continuous line joint, pivotally connected. Preferably container 11 and cover 16 consist of a common blank.

The package contents, here a group of the cigarettes 10 with an inner wrapper 18 to form a (cigarette) block 19, can be positioned directly in the container 11. In the present case, a preferably running around around inner frame 20 is disposed in the container 11, which rests against the inside of the container walls 12 ... 15 and consists of longitudinal webs 21, 22 and transverse webs 23, 24. The inner frame 20 limits the usable interior of the container 11. Conveniently, the inner frame 20 is dimensioned so that the longitudinal and transverse webs 21 ... 24 protrude beyond the boundary of the container 11. The package contents - cigarette block 19 - can find fitting in the limited by the inner frame 20 region of the container 11, so flush with a free edge of the inner frame 20.

The lid 16 is also box-shaped with top wall 42 and attached to this longitudinal lid walls 26, 27 and cover transverse walls 28, 29. The dimensions are chosen so that edges of the lid walls 26 ... 29 with the lid closed 16 suitable rest on corresponding edges of the container walls 12 ... 15 so that container 11 and lid 16 are flush in the closed position ( Fig. 1 . Fig. 3 ).

In order to facilitate the removal of the package contents, so in particular of the cigarettes 10, a lifting member 30 is disposed in the package, which lies within the container 11 under the cigarette block 19 and due to the automatic operation with the lid 16 open the cigarette block 19 in whole or in part the container 11 lifts out. Preferably, the lifting member 30 is configured and arranged so that the cigarette block 19 is brought into an inclined position ( Fig. 4 ), such that a removal side of the cigarette block 19 - the lid 16 swept - is increased, so that the individual cigarettes 10 are easily detected by the consumer.

The lifting member 30 has a resilient lifting part 43 which rests against the underside of the cigarette block 19. When the lid 16 is closed, the lifting part 43 is in a compressed position - by the pressed against the bottom wall 25 cigarette block 19. In this position, a voltage is built up, which is effective when opening the lid 16.

Lifting members 30 are preferably made of a deformed, in particular folded blank made of (thin) cardboard, plastic or a laminate. A simple embodiment of the lifting member 30 is in FIG. 3 and FIG. 4 shown. A substantially rectangular blank is folded along an approximately central transverse folding edge 31 to form two (approximately equal) legs. A bottom leg 31 is located on the bottom wall 25. A lifting leg 32 is relatively movable to the bottom leg 31 and is located on the bottom wall 25 facing the lower side of the cigarette block 19 at. The Hubschenkel 32 is deformable and elastically pivotable about the folding edge 31, and that from a folded or collapsed position according to Fig. 3 in a removal position according to Fig. 4 , The movement is effected by the inherent elasticity of the lifting leg 33 as a lifting part 43. The entire lifting member 30 and the lifting member 43 is adjacent to the hinge 17 of the lid 16 is arranged. The lifting member 30 is presently fixed in the container 11, by glue joints 34 between the bottom leg 32 and the bottom wall 25. When re-closing the lid 16 of the lifting leg 33 is moved back by lowering the cigarette block 19 in the starting position. The elastic clamping force is maintained.

A more complex variant of the lifting member 30 is in Fig. 5, Fig. 6 shown. The bottom leg 32 extends here over the full area of the bottom wall 25, so a positive positioning of the lifting member 30 is given without additional connecting means. A lifting part 43 is formed at an end portion of the (rectangular) blank. By zig-zag folding two Hubschenkel are formed, with a Hubschenkel 33 facing the cigarette block 19 and an intermediate leg 35 is connected via the folding edge 31 with the Hubschenkel 33 and a further folding edge 36 with the bottom leg 32. When lid 16 is closed ( Fig. 5 ) is composed of several legs lifting part 43 of the lifting member 30 is compressed, so that the legs 33, 35 to each other or on the bottom leg 32, with a corresponding clamping force, which is effective when opening the lid 16.

The embodiment according to Fig. 7, Fig. 8 corresponds in terms of the design of the lifting member 30 to the embodiment described above, however, is positioned yoodoch in the reverse position, so that the Hubschenkel 33 extends over the (approximately) full dimension of the bottom wall 25. Below the stroke limb 33 which acts as a full-surface covering, analogously to Fig. 5, Fig. 6 - An intermediate leg 35 attached. A relatively narrow bottom leg 32 is located on the bottom wall 25. The Hubschenkel 33 can, as shown, be firmly connected by a glue joint 34 with the bottom wall 25.

In the embodiment according to FIGS. 9 and 10 the lifting member 30 is formed with a lifting member 43 consisting of a plurality of cumulatively acting folds. A large-scale bottom leg 32, preferably in the dimensions of the bottom wall 25, is applied to this. By punching a tongue is exposed as part of the bottom leg 32. This tongue has a smaller width than the corresponding dimension of the bottom leg 32 (FIG. Fig. 12 ). The tongue is folded along a transverse main edge 37. The bottom leg 32 thereby has a recess 38, corresponding to the dimension of the tongue. This is folded so that it faces the cover 16 and the hinge 17. The tongue forms a main leg 39, which faces the underside of the cigarette block 19. By a further punching preferably only in the central region of the main leg 39 and the bottom leg 32, a corresponding portion of the main leg 39 can be folded again, forming at least two Z- or V-shaped auxiliary legs 40, 41. These are on the one hand the bottom leg 32 supported (auxiliary leg 40) and on the other hand pivotally connected to the main leg 39 (additional leg 41). The Accordingly, when the lid 16 is open, the lifting force acting on the cigarette block 19 is formed from a plurality of cooperating lifting parts, in this case with the main leg 39 and the additional legs 40, 41.

The execution according to Fig. 9, Fig. 10 is in perspective Fig. 12 shown. Fig. 11 shows a corresponding representation for the example according to Fig. 7, Fig. 8 ,

A fixation of the lid 16 in the closed position is advantageous. In the present case, the closed lid 16 is fixed on the container 11 via elastic coupling members, such that the lid 16 can be lifted during opening without any special application of force. Inner frame 20 on the one hand and cover walls 26..28 on the other hand are provided with projections or recesses, which come into mutual engagement in the closed position. In the illustrated embodiment, the front side, remote from the hinge 17 transverse web 23 of the inner frame 20 is provided with a projection, namely with a by U or. C-shaped punching 44 formed tongue 45. This is directed by appropriate deformation with an edge region to the outside or to the free side, thus forming a projection or hook.

The lid 16 is provided with a counter-organ. This is in the embodiment shown in an opening 46 formed by punching in the region of the front lid transverse wall 28. This is provided by folding with an inner leg 47, which preferably extends over the full width of the lid 16 and the lid transverse wall 28 , The inner leg 47 is provided with the opening 46, at the location of the tongue 45, preferably in the middle of the pack. In the closed position, the downwardly facing tongue 45 enters like a barb in the opening 46 and fixes the lid 16. To compensate for the wall thickness and the front transverse wall 14 of the container 11 is provided with an inwardly folded wall strip 48, so in the region of this front Walls container 11 and cover 16 double-layered lie together.

A special feature is the production or filling of the package with the introduction of the lifting member 30. The finished in principle Kappenschachteln be supplied to a packing conveyor 49 in the closed position. This is designed here as an endless conveyor, namely as a belt with upper conveying strand 50. The packing conveyor 46 is arranged with a plurality of spaced, in cross-section U-shaped Bags 51 are provided, which are open in the region of the conveying strand 50 upwards and transversely to the conveying direction, so that the cap boxes can be inserted via a transverse Zuförderbahn in each case 51 a pocket.

In the region of an opening station 52, the cap box is opened by suitable organs during the momentary standstill of the package conveyor 49. The container 11 remains in the pocket 51 while the lid 16 is pivoted to the free side. Fixed guide members, namely guide rails 53, 54, fix the cap box in the pocket 51 and the lid 16 in the open position.

In the area of a first filling station 55, the blank of the lifting member 30 is supplied and - after folding - transferred from above into the container 11, in compressed, so tense position. The folding of the blank can be done in a suitable manner. Above the respective cap box or the container 11, a cutting member 56 which can be moved up and down is arranged, which grasps the lifting member 30 and introduces it into the container 11 by lowering. The blanking member 56 is designed such that the respective lifting member 30 is detected in folded or tensioned formation ( Fig. 15 ).

The blanking member 56 has a plurality of - in the present case two - suction members 57, 58. These are arranged on a common carrier 59 and are acted upon by this controlled with suction. The suction members 57, 58 are provided with elastic suction cups, which receive at the top of the lifting member 30 conditioning and hold it by means of negative pressure. A special feature is that the suction member 57 in the region of the lifting part 43 of this fixed in the initial or folding position in which the legs 32, 33, 35 ( Fig. 7, Fig. 8 ) lie against each other. This position is effected by meaningfully positioned punched holes 60, 61 in the region of the legs, here in the region of the lifting leg 33 and the intermediate leg 35. The punched holes 60, 61 are arranged so that they overlap congruently with folded legs. The suction air of the suction member 57 can be transmitted via the congruent holes 60, 61 on the free leg 32.

After placing the lifting member 30 in the container 11, the lifting member 43 is fixed by a stationary hold-down 62 in further transport.

In the immediately following another filling station, namely a block station 63, the transversely supplied cigarette blocks 19 are lowered from above into the container 11 while compressing the lifting member 30. Thereafter, the lid 16 is pivoted in the usual manner from the opening to the closed position.

When the lifting member 30, namely its bottom leg 32, is adhesively attached to the bottom wall 25 of the container, the packing is produced or filled in such a way that glue areas or glue spots for the glue joints 34 are applied to the bottom wall 25, before the lifting member 30 is inserted in the filling station 55 in the container 11. In this case, the filling station 55 is preceded by a glue station 65 in which, when the lid 16 is open, glue spots or the like are applied to the bottom wall 25 via a stationary glue valve 66 arranged above the movement path of the packs. Immediately thereafter, the blank of the lifting member 30 is inserted into the container 11.

The present technique with respect to the configuration of the cap boxes and the filling thereof is particularly suitable for cigarette blocks 19 from a sealed inner casing 18 with a multiply operated opening tab 64, which on the lid 16 and the hinge 17 side facing a removal opening in the inner sheath 18th vacant. The opening tab 64 is provided at the edge with a permanent adhesive and so for reclosing on the inner sheath 18 in the region of the removal opening can be fixed.
