Description

Case with folding lid for cigarettes.

The invention concerns a lid pack folding made of thin cardboard or similar packaging material and destined to receive a group of cigarettes, which consists of a part of pack, a cover and a necklace, with package edges vertical, namely the longitudinal edges, and with edges transversal that run in a transverse direction to these.

Flip-up cigarette packs They have been known for many decades. In the last times, the vertical edges of the package are provided with a chamfer, with which results in an octagonal general form of the package (document DE 100 47 447). Individual parallel songs in the area of the chamfers are determined by a different deformation of the packaging material, specifically a die cut preform for the flip cover box. Stretch marks formed in the cardboard Thin die-cut preforms are configured with Different size and / or shape. As a result, an outline of package in which the parallel edges do not have protrusions or Significant entrees in the area of the chamfers.

Also, the material treatment is known of cardboard, namely the folding of cardboard material located in double layer and glued with itself (document DE 1 017 013). In this case, proceed so that the two layers are provided with different prints in the area of a folding edge rectangular to be produced. One of the layers presents a stamped stria, while the other layer is provided with two parallel stretch marks with a groove arranged between them and directed in the opposite direction. When folding the two layers of glued material with each other there is a thickening of the material by way of flange on the inner side of the folding edge.

The invention is based on the problem of set up a flip lid pack for cigarettes so that is provided through the configuration made a increased stability against mechanical loads.

To solve this problem, the pack of flip cover of the invention is characterized, according to a first embodiment, for the following particularities:

a) the longitudinal edges and / or the edges cross-sections have been configured, due to deformation or stamping of the packaging material, such as a round projection directed towards outside,

b) the projection has a sectional shape transverse corresponding to approximately three quadrants of circle,

c) the projection joins with a respective edge intermediate to pack walls or adjacent folding flaps.

Therefore, in the lid box folding strips according to the invention are deformed strips of material for give them the configuration of circle arcs, so that they alternatively obtain an outwardly directed thickening with the cross-sectional shape of three circle quadrants or a ledge directed inward with the sectional shape cross of a circle quadrant. In both cases, some strips of material limited by intermediate edges have been deformed to Give them the shape of circle arcs. The package thus gets a net improvement of its stability.

The characteristics of the claims subordinates refer to the configuration of a usual necklace in flip-top and wall configuration packs lateral.

Folding lid packs consist of typically in a box part (bottom) 10 and a lid (top) 11. In addition, a collar 12 is an integral part of the flip lid box. The pack part 10 and the cover 11 they are linked to each other in a tiltable way through a line of rear articulation 13. Therefore, the pack part 10 and the lid 11 has been made from a common die cut preform (for example, figure 6). The content of the package is the present case a group of cigarettes 48 that is surrounded by a preform die cut 49.

The die cut preform for the lid pack folding is configured in the examples of embodiment shown so that delimited areas intended for form a front wall 14 of the pack, a bottom wall 15, a rear wall 16 of the pack, a rear wall 17 of the  lid, a head wall 18 and a front wall 19 of the lid. On the free edge of the front wall 19 of the lid is applied an inner flap 20 of said lid which, in the lid pack Folding finished, is folded against the inner side of the front wall 19 of the lid.

To form the side walls 21 of the pack and the side walls 22 of the lid have been arranged laterally on the walls described folding flaps, to namely, inner side flaps 23 of the pack and some outer side flaps 24 of said pack. In the area of the flaps are provided correspondingly inner sides 25 of the lid and side flaps exterior 26 of said cover. The side flaps 23 and 24 of the pack overlap each other to form the walls sides 21 of said packet. The side flaps 25, 26 of the cap overlap correspondingly and join with another to form the side walls 22 of said cover.

In the inner side flaps 23 of the pack and on the inner side flaps 25 of the lid are arranged additional folding flaps, namely flaps corner 27 of the bottom, on the one hand, and corner flaps of The head, on the other. These folding flaps are applied in the folding lid box finished on the inner side of the wall bottom 15 and to the inner side of the head wall 18, respectively.

The folding side flaps 23, 24, 25, 26 are delimited with respect to walls 14, 16, 17, 19 by some folding lines, namely by folding lines Longitudinal, which in the package finished so parallelepipedic (for example, figure 1), form some songs verticals of said package, namely the longitudinal edges 29, 30. These extend in the area of the pack part 10 and the cover 11.

The front wall 14 of the pack, by a side, and the rear wall 16 of said packet, on the other, are delimited with respect to the bottom wall 15 by means of transverse folding lines that form in the finished package horizontal transverse edges 31, 32 oriented in any case in the transverse direction to the longitudinal edges 29, 30. In the area of the lid 11 they are formed so corresponding transverse edges 33, 34 to delimit the head wall 18 with respect to the rear wall 17 of the lid, on the one hand, and on the front wall 19 of said cover, on the other.

The longitudinal edges 29, 30, on the one hand and the transverse edges 31 ... 34, on the other, have been configured as a special way by deformation of the material or stamping of the same. According to the embodiment example of figure 1 and the Figure 2, the vertical longitudinal edges 29, 30 are configured in the form of protrusions 35 of cross section round directed out. In the example of special embodiment shown is about protrusions 36 of cross section in shape circle part, that is, approximately in the form of three circle quadrants. The projection 35 joins with a respective edge intermediate 36, 37 to the adjacent folding walls or flaps. The longitudinal edges 29, 30 configured as a projection 35 of circle part form extend continuously in the area of the part of pack 10 and then in the area of the lid 11, a know, in the area of the four longitudinal edges 29, 30.

The preform die cut (figure 6) is prepared for the manufacture of a folding lid box according to the Figure 1 and Figure 2. Conveniently, when producing the preform die cut is made in the area of longitudinal edges 29, 30 a deformation, which in the present embodiment is a stamped 46 semicircularly (figure 8). Also, the die cut preform is configured in a special way in the area of the corner flaps 27 at the bottom and on the flaps of corner 28 of the head (figure 7). Corner flaps corresponding 27, 28 have been shortened by means of a die cut 38 forming a distance from the corresponding corner flap 27, 28 to the adjacent folding flap. In addition, the deformations or prints 46 intended to form the protrusions 35 are limited at the ends by a cross-sectional cut 39 which extends beyond the width of the shoulder 35 and makes thus possible a deformation without stress of the projection 35 during the folding process in relation to the bottom wall 15 or the wall Headed 18.

The folding flaps of the side walls 21 of the pack and the side walls of the lid are dimensioned so that they overlap each other in an area between the associated projections 35, that is to say extend from intermediate edge 36 to intermediate edge 37.

In the exemplary embodiment according to figure 3 the vertical longitudinal edges 29, 30 of the lid pack Folding are configured in the form of an entrant 40. This is also arc-shaped or circular in section transversal, specifically with the dimensions of a quadrant of circle. The intermediate edges 36, 37 are directed here towards outside.

A peculiarity is that for package shapes according to figure 1 and figure 2, on the one hand, and Figure 3, on the other hand, almost pre-punched preforms can be used matching in the form according to figure 6. In any case, in the area of the projections 35 or the entrances 40 to be produce the 46 shaped shapes are provided of stretch marks, made specifically during the production of projections 35 with a bulge towards the printed side of the preform die cut and during the production of starters 40 with a bulging towards the inner side not printed.

The production of the projections 35 or Starters 40 takes place in a simple special way. The stamping 46 made (approximately) in the shape of a semicircle in cross section it is deformed by folding a flap folding, namely, especially by folding the flaps sides 23, 24 of the pack and side flaps 25, 26 from the lid to a position transverse to the adjacent walls of the package, thereby forming a protrusion 35 or a recess 40. According to figure 9, the result of a stamping 46 of the figure 8 is a circle quadrant shaped recess 40, whose dimension (radius) is somewhat larger than the corresponding dimension of the stamping 46. When folding the folding flaps mentioned to form projections 35 results in a reduction in the dimensions of the three circle quadrants thus created (figure 10). Regarding the Figure 8, it is fulfilled that, according to the shape of the package edge that is want to produce, stamping 45 is directed towards one or the other side of the preform die cut.

The dimensions of the prints 46, for a side, and outgoing 35 or incoming 40, on the other, can be chosen in accordance with the purpose of the configuration. They are advantageous dimensions of the projections 35 or the recesses 40 with a radius r of 1.5 mm to 4 mm.

The collar 12 may be configured with a corresponding adaptation to the contour for one or another embodiment of the folding lid box. As usual, collar 12 consists of a front wall 41 and side flaps 42 transversely folded. Between them some songs are formed vertical 43, 44 of the collar, which are associated with the longitudinal edges 29, 30 of the front side. As shown to the left in figure 11, collar 12 for a lid pack folding according to figure 1 and figure 2 has edges 43 that are configured as a projection with the sectional shape cross of three circle quadrants. The dimensions of the edges 43 of the collar or projections are adapted to the dimensions of the projections 35 of the longitudinal edges 29, 30

Similarly, collar 12 is configured according to figure 11 on the right for a container of the embodiment according to figure 2, specifically with edges 44 of said collar which They are set as incoming in the form of a circle quadrant. Because of the changing geometric relationships, in this package (figure 3) an adapted configuration of the edges is important 44 of the necklace. In the package according to figure 1 and figure 2, you can also insert a conventional collar whose edges form a right angle in cross section.

Alternatively or additionally, some or all transverse edges 31 ... 34 can be configured with a deformation, namely defining a projection 35 of the described embodiment or a recess 40. Figure 12 to Figure 15 show details of a flip lid box in which the four transverse edges 31 ... 34 of the pack part 10 and of the cover 11 are formed with protrusions 35 extending by the entire width of the flip lid box.

The die cut preform (figure 13) is configured so that the transverse folding lines or the transverse edges 31 ... 34 are provided with a groove 47 performed (approximately) semicircularly by deformation or stamping When folding the front wall 14 and the rear wall 16 of the pack in relation to the bottom wall 15, as well as the fold the front wall 19 and the rear wall 17 of the lid with in relation to the head wall 18, said groove forms protrusions round 35 with a cross section in the form of three quadrants circle (figure 14). As an alternative, the cross edges 31 ... 34 of the flip cover box can be configured in the form of starters analogous to the starters according to figure 9. However, this embodiment assumes that the contents of the package is adapted to the small interior dimensions of the flip lid box.

A particularity is the formation of corner flaps 27 of the bottom and corner flaps 28 of the head. Due to a die cut 45 and a reduced width in comparison with the adjacent side flaps 23 of the pack and adjacent side flaps 26 of the lid, said flaps of corner are configured so that, when the package is folded, the corresponding corner flaps are located so adequate and in any case in a centered position between the edges shaped cross-sections 31 ... 34. In this embodiment (figure 13) of the preform die cut the folding flaps interiors 23, 25, 27, 28 are configured with a width continuously equal reduced compared to that of the flaps folding 24, 26.
