Description

Hinge-LID PACKET FOR CIGARETTES}

The present invention relates to a hinged lid box for cigarettes made of thin cardboard or similar packaging material comprising a box portion, a lid and a collar and having vertical longitudinal and transverse edges.

The hinged lid box is a cigarette pack known worldwide. But hinged lid boxes are also suitable packaging for use in other products such as chocolates and candies.

It is known that a hinged lid pack for cigarettes has a box portion and a rounded or inclined vertical longitudinal edge of the lid. By having a pack edge of this shape, the hinged lid pack matches the contents of the pack, ie the appearance of the tobacco group.

The present invention is based on the object of realizing improvements and developments of hinged lid boxes for tobacco and other products such that the finished box provides improved dimensional stability against mechanical loads.

To achieve this object, the hinged lid box according to the invention deforms the packaging material such as an outwardly directed projection with a rounded cross section or an inwardly recessed section with a rounded cross section with a longitudinal edge and / or a transverse edge. Or by embossing.

Preferably the protrusions and recesses are formed to have circular cross sections. The protrusion has a cross-sectional shape of 3/4 circle. The concave portion has a cross-sectional shape of 1/4 circle.

This contour of the four vertical longitudinal edges and / or the upper transverse edge and the lower transverse edge to border the end face and the base wall achieves a clear improvement in the dimensional stability of the pack against pressure loads. This also applies to longitudinal loads and transverse loads depending on the arrangement of the protrusions or recesses.

When a vertical longitudinal edge is formed with a protrusion, the collar can be formed and used with a conventional right angle collar edge. However, suitably the collar exhibits an appearance corresponding to the box portion and the lid in the region of the vertical collar edge.

The blank for the hinged lid box also features a special shape in the region of the base wall and the end face. This also applies to the manufacture of the hinged lid box by folding the blank. The blank has embossing in the region of the baler or in the region of the longitudinal and / or transverse edges which can be applied during the manufacture of the blank. The blank is processed to form or emboss a groove having a semicircular cross section. Depending on the shape of the pack edge to be produced, the folding tab is folded in one or the other to thereby create a circular protrusion with a radius reduced from the semi-circular reinforcement shim or a quarter circular recess with an enlarged radius. .

The features of the hinged lid box and the blank for producing the box are described in more detail below on the basis of the exemplary embodiment shown in the drawings.

The standard hinged lid pack includes a lower box portion 10 and an upper lid 11. In addition, the collar 12 constitutes a part of the hinged lid box. The box portion 10 and the lid 11 are connected to each other by a hinge line 13 on the rear side. Thus, the box portion 10 and the lid 11 are formed of a common blank (see FIG. 6). In the case of the present invention, the pack contents are tobacco groups 48 surrounded by an inner liner 49.

The blanks for the hinged lid packs are in the illustrated exemplary embodiment the box front wall 14, the base wall 15, the box rear wall 16, the lid back wall 17, the end wall 18 and the lid front. The bordered zones are formed to be continuous with each other to form the barrier 19. Attached to the free edge of the lid front wall 19 is a lid inner tab 20 that is folded against the inside of the lid front wall 19 in the finished hinged lid pack.

In order to form the box side wall 21 and the lid side wall 22, the side tabs are attached to the aforementioned wall, in particular the inner box side tab 23 and the outer box side tab 24. Corresponding inner lid side tabs 25 and outer lid side tabs 26 are provided in the region of the lid. The box side tabs 23, 24 overlap each other to form a box side wall 21. Correspondingly, the lid side tabs 25, 26 overlap and connect with one another to form the lid side wall 22.

Additional folding tabs are attached to the inner box side tab 23 and the inner lid side tab 25, ie on the base corner tab 27 on the one hand and on the end corner tab 28 on the other.

In the finished hinged lid pack this folding tab is placed against the inside of the base wall and the inside of the end wall 18 respectively.

The lateral folding tabs 23, 24, 25, 26 are formed by folding lines which form vertical pack edges, in particular longitudinal edges 29, 30, in the finished cuboid shaped pack (see FIG. 1), ie at the longitudinal edges. By walls 14, 16, 17, 19. It extends to the area of the box part 10 and the lid 11.

The box front wall 14 and the box back wall 16 are transverse folding lines that form horizontal transverse edges 31 and 32 which extend in any case to the longitudinal edges 29 and 30 in the finished pack. Is bound from the base wall 15. Correspondingly, the transverse edges 33, 34 are zones of the lid 11 for the purpose of bordering the end wall 18 from the lid back wall 17 on the one hand and the lid front wall 19 on the other hand. Is formed.

The longitudinal edges 29, 30 and the transverse edges 31, 32, 33, 34 are formed in a special way by material deformation or embossing. In accordance with the exemplary embodiment of FIGS. 1 and 2, the vertical longitudinal edges 29, 30 are formed as outwardly directed projections 35 with rounded cross sections. In the exemplary embodiment shown, this is a projection 35 having a cross-sectional shape of a pitch circle, ie in the form of a 3/4 circle. The protrusion 35 is attached to the adjacent wall and the folding tab by intermediate edges 36, 37. The longitudinal edges 29, 30 formed as protrusions 35 in the shape of the pitch circle extend in the region of the box portion 10 and in particular in the region of the lid 11 of all four longitudinal edges 29, 30. Continue without interruption in the area.

The blank (see FIG. 6) is prepared for the production of the hinged lid pack according to FIGS. 1 and 2. Suitably, deformation takes place in the region of the longitudinal edges 29, 30 during the manufacture of the blank, in this embodiment a semicircular embossing 46 (see FIG. 8). In addition, the blank has a special shape in the region of the base corner tab 27 and the end corner tab 28 (see FIG. 7). The corner tabs 27 and 28 are shortened by punching 38 which forms a space between the appropriate corner tabs 27 and 28 and the adjacent folding tabs. Moreover, the deformation or embossing 46 for forming the projection 35 is limited at its end by a transverse incision 39 which extends beyond the width of the projection, so that the base wall 15 or It allows for an unstressed deformation of the projection 35 with respect to the end wall 18.

The folding side tabs of the box side wall 21 and the lid side wall are dimensioned to overlap in the region between the associated protrusion 35, ie extending from the middle edge 36 to the middle edge 37.

In the exemplary embodiment according to FIG. 3, the vertical longitudinal edges 29, 30 of the hinged lid pack are formed as recesses 40. The cross section also has the form of a curved or circle, in particular having a dimension of 1/4 circle. The intermediate edges 36, 37 here are oriented outwards.

One feature is that substantially identical blanks of the form according to FIG. 6 can be used on the one hand for the pack form according to FIGS. 1 and 2 and on the other hand for the pack form according to FIG. 3. In each case, the embossing 46 is in particular a bulge 35 or a bulge of the printed side of the blank for making the projection 35 and a bulge of an unprinted inner side for making the recess 40. In the area of 40 is provided.

The protrusion 35 or the recess 40 is made in a particularly simple manner. An embossing 46 having a substantially semicircular cross-sectional shape is provided with the box side tabs 23 and 24 by folding the folding tabs, i.e., transverse to the adjacent pack wall to form the protrusions 35 or recesses 40. It is formed by folding the lid side tabs 25, 26. According to FIG. 9, the embossing 46 of FIG. 8 makes a quarter circle recess 40, the radial dimension of which is slightly larger than the corresponding dimension of the embossing 46. When the folding tab is folded to form the projection 35, the dimension of the three quarter circle produced thereby is reduced. With respect to FIG. 8, the embossing 46 is oriented towards one or the other side of the blank, depending on the shape of the pack edge to produce.

On the one hand the dimensions of the embossing 46 and on the other hand the protrusion 35 or the recess 40 can be selected according to the desired design. Advantages in this respect are the dimensions of the protrusions 35 or the recesses 40 having a radius of 1.5 mm to 4 mm.

The collar 12 may be formed to correspond to one embodiment or another embodiment of the hinged lid pack. In general, the collar 12 includes a collar flap 42 that is folded in the transverse direction of the collar front wall 41. Formed between them are the vertical collar edges 43, 44 associated with the longitudinal edges 29, 30 of the front side. As shown on the left in FIG. 11, the collar 12 for the hinged lid pack according to FIGS. 1 and 2 has a collar edge 43 formed as a protrusion having a 3/4 circle cross-sectional shape. The dimensions of the collar edge 43 or the protrusions coincide with the dimensions of the protrusion 35 of the longitudinal edges 29, 30.

Likewise, a collar 12 as shown on the right in FIG. 11 is formed for a pack embodiment according to FIG. 3, ie with a collar edge 44 designed as a quarter circle recess. Because of the geometric correlation, the proper design of the collar edge 44 is important for this pack (see Figure 3). For the pack according to FIGS. 1 and 2, it is possible to use a general collar with collar edges having a right angle cross section.

Alternatively or additionally, individual or all transverse edges 31, 32, 33, 34 may be formed to form one of the protrusions 35 or recesses 40 of the above-described embodiment. 12-15 show the box portion 10 and all four transverse edges 31, 32, 33, 34 of the lid 11 with recesses 35 extending across the full width of the hinged lid pack. The details of the hinged lid pack formed are shown.

The blank (see FIG. 13) is formed such that the transverse folding line or the transverse edges 31, 32, 33, 34 are provided with an approximately semi-circular reinforcement shim formed by molding or embossing. When the box front wall 14 and the box rear wall 16 are folded with respect to the base wall 15 and the lid front wall 19 and the lid back wall 17 are folded with respect to the end wall 18, the reinforcement Shim 47 forms a rounded projection 35 with a 3/4 circle cross section (see FIG. 14). Alternatively, the transverse edges 31, 32, 33, 34 of the hinged lid pack can be formed as recesses similar to the recesses according to FIG. 9. However, this embodiment requires adjusting the pack contents to fit the reduced inner dimensions of the hinged lid pack.

One unique feature is the shape of the base corner tab 27 and the end corner tab 28. Because of the reduced width and punching compared to adjacent box side tabs 23 and lid side tabs 26, the corner tabs are interposed between the transverse edges 31, 32, 33, 34 formed in any case in the finished pack. It is formed to be properly placed. In this exemplary embodiment of the blank (see FIG. 13), the inner folding tabs 23, 25, 27, 28 are formed continuously with the same width reduced with respect to the folding tabs 24, 26.
