Abstract

The flip pack of thin card or suchlike, especially for cigarettes, has the longitudinal edges (29,30) and transverse edges (31-34) constructed by forming of the packing material as an outwards orientated protrusion (35), which is round in cross section, or as an inwards orientated recess which is also round in cross section. The edges constructed as a protrusion have a part circle form cross section, approximately in the form of a three quarter circle, and the edges constructed as a recess have a part circle form cross section, approximately in the form of a quarter circle.

Description

The invention relates to a folding box made of thin cardboard or similar packaging material for receiving a group of cigarettes, consisting of box part, lid and collar with upright packing edges, namely longitudinal edges and transverse to these transverse edges.

Folding cartons for cigarettes have been known for many decades. More recently, upright packaging edges have been bevelled to create an overall octagonal shape of the package ( DE 100 47 447 ). The parallel individual edges in the region of the chamfers are determined by different deformation of the packaging material, namely a blank for the folding box. The grooves formed in the thin board of the blanks are formed with different sizes and / or shapes. As a result, a packing contour is created in which the parallel edges in the area of the chamfers have no significant protrusions or recesses.

Furthermore, the treatment of cardboard material is known, namely the folding of double-glued and glued cardboard material ( DE 1 017 013 ). In this case, the procedure is such that the two layers are provided with different imprints in the region of a right-angled folding edge to be produced. One of the layers has a stamping groove, while the other layer is provided with two parallel grooves with an oppositely directed groove therebetween. During the folding of the two bonded-together material layers, a bead-like material thickening arises on the inside of the folded edge.

The invention has for its object to form a folding box for cigarettes so that is given by the design of increased dimensional stability to mechanical loads.

1. a) die Längskanten und/oder die Querkanten sind durch Verformen bzw. Prägen des Verpackungsmaterials als nach außen gerichteter, runder Vorsprung ausgebildet,
2. b) der Vorsprung weist eine Querschnittsform etwa eines Dreiviertelkreises auf,
3. c) der Vorsprung schließt mit jeweils einer Zwischenkante an angrenzende Packungswände bzw. Faltlappen an.

To solve this problem, the folding box according to the invention is characterized according to a first embodiment by the following features:

1. a) the longitudinal edges and / or the transverse edges are formed by deforming or embossing the packaging material as an outwardly directed, round projection,
2. b) the projection has a cross-sectional shape of about a three-quarter circle,
3. c) the projection adjoins adjacent packing walls or folding flaps, each with an intermediate edge.

1. a) die Längskanten und/oder Querkanten sind durch Verformen bzw. Prägen des Verpackungsmaterials als nach innen gerichteter, im Querschnitt runder Rücksprung ausgebildet,
2. b) der Rücksprung weist eine Querschnittsform etwa eines Viertelkreises auf,
3. c) der Rücksprung schließt mit jeweils einer Zwischenkante an angrenzende Packungswandungen bzw. Faltlappen an.

According to an alternative, the folding box according to the invention is characterized by the following features:

1. a) the longitudinal edges and / or transverse edges are formed by deforming or embossing the packaging material as inwardly directed, in cross-section round recess,
2. b) the recess has a cross-sectional shape of about a quarter circle,
3. c) the recess adjoins adjacent packing walls or folding flaps, each with an intermediate edge.

In the folding box according to the invention, therefore, strips of material are deformed in a circular arc such that alternatively an outwardly directed thickening with the cross-sectional shape of a three-quarter circle or an inward projection with the cross-sectional shape of a quarter circle is formed. In both cases, strips of material bounded by intermediate edges are deformed in a circular arc. This gives the pack a significant improvement in stability.

Features of the dependent claims relate to the design of a usual folding boxes collar and the design of side walls.

By default, folding boxes consist of a (lower) box part 10 and a (top) cover 11. Furthermore, a collar 12 is part of the folding box. Box part 10 and lid 11 are pivotally connected to each other via a rear hinge line 13. Box part 10 and lid 11 are therefore from a common blank (eg. Fig. 6 ) educated. Package contents in the present case is a cigarette group 48 which is surrounded by an inner blank 49.

The blank for the folding box is designed in the embodiments shown that delimited areas to form a box front wall 14, bottom wall 15, box rear wall 16, lid rear wall 17, end wall 18 and lid front wall 19 consecutively. At the free edge of the lid front wall 19, a lid inner tab 20 is attached, which is folded in the finished folding box against the inside of the lid front wall 19.

For forming box side walls 21 and lid side walls 22, folding flaps are attached laterally to the described walls, namely inner box side flaps 23 and outer box side flaps 24. Correspondingly, in the area of the lid, inner lid side flaps 25 and outer lid flaps 25 are provided. Side tabs 26 are provided. The box side flaps 23 and 24 overlap one another to form the box side walls 21. Accordingly, the lid side flaps 25, 26 are made to overlap and interconnect to form the lid side panels 22.

At the inner box side tabs 23 and the inner lid side flap 25 more folding flaps are mounted, namely bottom corner tabs 27 on the one hand and end-corner tabs on the other. These folding flaps are in the finished folding box on the inside of the bottom wall 15 and on the inside of the end wall 18 at.

The lateral folding tabs 23, 24, 25, 26 are delimited from the walls 14, 16, 17, 19 by fold lines, namely by longitudinal fold lines, which in the finished cuboid pack (eg. Fig. 1 form upright edges of the package, namely longitudinal edges 29, 30. These extend in the region of the box part 10 and lid 11th

The box front wall 14 on the one hand and the box rear wall 16 on the other hand are delimited from the bottom wall 15 by transverse folding lines, which form in the finished package horizontally extending, at least transverse to the longitudinal edges 29, 30 directed transverse edges 31, 32. Correspondingly, in the region of the cover 11, transverse edges 33, 34 are formed to delimit the end wall 18 relative to the cover rear wall 17 on the one hand and the cover front wall 19 on the other hand.

The longitudinal edges 29, 30 on the one hand and the transverse edges 31..34 on the other hand are formed by material deformation or embossing in a special way. According to embodiment of the Fig. 1 and Fig. 2 the upright longitudinal edges 29, 30 are formed as outwardly directed, cross-sectionally round projections 35. In the particular embodiment shown are part-circular projections 36 in cross-section, namely approximately in the form of a three-quarter circle. The projection 35 in each case adjoins the adjoining walls or folding flaps with an intermediate edge 36, 37. The formed as a part-circular projection 35 longitudinal edges 29, 30 extend in the region of the box part 10 and then in the region of the lid 11 continuously, in the region of all four longitudinal edges 29, 30th

The cut ( Fig. 6 ) is for the production of a folding box according to Fig. 1 and Fig. 2 prepared. Conveniently, in the production of the blank in the region of the longitudinal edges 29, 30, a deformation is made, in the present embodiment, a semi-circular embossing 46 (FIG. Fig. 8 ). Furthermore, the blank in the area of the bottom corner tabs 27 and the end corner tabs 28 is designed in a special way ( Fig. 7 ). The respective corner tabs 27, 28 are shortened by a punching 38, which forms a distance of the respective corner flap 27, 28 from the subsequent folding flap. Furthermore, the indentations 46 for forming the protrusions 35 are bounded at the ends by a transverse separating cut 39 which extends beyond the width of the protrusion 35 and thus stress-free deformation of the protrusion 35 during the folding process relative to the bottom wall 15 or End wall 18 allows.

The folding flaps of the box sidewalls 21 and lid sidewalls are dimensioned to overlap one another in an area between the associated projections 35, ie to extend from intermediate edge 36 to intermediate edge 37.

In the embodiment according to Fig. 3 the upright longitudinal edges 29, 30 of the folding box are formed as a recess 40. Also, this is arcuate in cross section or circular, with the dimensions of a quarter circle. Between edges 36, 37 are directed outward here.

A special feature is that for the packaging according to Fig. 1, Fig. 2 on the one hand and Fig. 3 on the other hand almost matching blanks in the form according to Fig. 6 can be used. In any case, are in the range of produced Projections 35 or recesses 40 provided the molded, groovelike embossments 46, in the production of protrusions 35 with a bulge to the printed side of the blank and in the production of recesses 40 with a curvature to the unprinted inside.

The preparation of the projections 35 or recesses 40 is in a special, simple manner vonstatten. The semi-circular (approximately) semi-circular embossment 46 is formed by folding a folding tab, specifically by folding the box side tabs 23, 24 and lid side tabs 25, 26 into a position transverse to the adjacent package walls to form tab 35 or Return 40 deformed. According to Fig. 9 results from an imprint 46 of the Fig. 8 a quarter circle-shaped recess 40 whose dimension (radius) is slightly larger than the corresponding dimension of the embossing 46. The folding of said folding tabs to form projections 35 results in a reduction in the dimensions of the three-quarter circle thus created (FIG. Fig. 10 ). Regarding Fig. 8 applies that the embossment 45 is directed to one or the other side of the blank depending on the shape of the packaging edge to be produced.

The dimensions of the embossments 46 on the one hand and the projections 35 or recesses 40 on the other hand can be selected depending on the design goal. Advantageously, dimensions of the projections 35 and recesses 40 with a radius r of 1.5mm to 4mm.

The collar 12 may be designed for one or the other embodiment of the folding box with appropriate adaptation to the contour. The collar 12 consists, as usual, of collar front wall 41 and lateral, cross-folded collar flap 42. In between are upright collar edges 43, 44 are formed, which are associated with the front longitudinal edges 29, 30. As in Fig. 11 , shown on the left, the collar 12 for a folding box according to Fig. 1 and Fig. 2 Collar edges 43 which are formed as a projection having the cross-sectional shape of a three-quarter circle. The dimensions of the collar edges 43 and the projections are adapted to the dimensions of the projections 35 of the longitudinal edges 29, 30.

In an analogous manner, the collar 12 is according to Fig. 11 , right for a package of execution according to Fig. 3 formed, namely with collar edges 44, which are designed as a quarter-circle recesses. Because of the geometric interrelationships in this pack ( Fig. 3 ) an adapted configuration of the collar edges 44 important. In the package according to Fig. 1 and Fig. 2 is also a conventional collar with rectangular cross-section collar edges used.

Alternatively or additionally, individual or all transverse edges 31... 34 may be formed with a deformation, either to form a projection 35 of the embodiment described or with a recess 40. FIGS. 12 to 15 show details of a folding box, in which all four transverse edges 31..34 of the box part 10 and the lid 11 are formed with projections 35 which extend over the entire width of the folding box.

The cut ( Fig. 13 ) is formed so that the Querfaltlinien or transverse edges 31..34 are formed with a formed by deformation or embossing, (approximately) semicircular bead 47. This forms in the folding of box front wall 14 and box rear wall 16 relative to the bottom wall 15 and in the folding of lid front wall 19 and lid rear wall 17 relative to the end wall 15 round projections 35 with a cross section of a three-quarter circle ( Fig. 14 ). Alternatively, the transverse edges 31..34 of the folding box may be formed as recesses, analogous to the recesses according to Fig. 9 , However, this design assumes that the package contents are adapted to the reduced internal dimensions of the folding box.

A special feature is the formation of the bottom corner tabs 27 and end corner tabs 28. These are due to a punching 45 and due to reduced width compared to the adjacent box side tabs 23 and lid side tabs 26 formed so that in the folded package the Corresponding corner tabs suitably, at least centrally between the shaped transverse edges 31..34 lie. In this embodiment ( Fig. 13 ) of the blank, the inner folding tabs 23, 25, 27, 28 are formed with the same continuous, compared to the folding tabs 24, 26 reduced width.
