Description

  The present invention is a pack comprising two pack parts: an outer pack with at least one front wall, ie an outer front wall, and an inner part with at least one front wall, the inner wall of the inner part Are connected to the inside of the outer front wall by a connecting plate or a hinge plate provided on the inner wall, and the outer pack portion, i.e., the partial pack, is centered on the hinge on the bottom side to the open position and the closed position. The present invention relates to a pack that is relatively swingable.

  A cigarette pack comprising two partial packs that are pivotably coupled is known from US Pat. These two partial packs are connected to each other in a swingable manner in the common bottom wall region. In the open position, both partial packs are arranged in the expanded position. These partial packs together form an outer pack. The outer pack is connected to the inner part of the pack, i.e. the deformed collar, in the region of the outer front wall. The outer pack has a coupling plate or a hinge plate, which is formed on the lower edge of the collar as a part or extension of the collar front wall. In order to move the hinge plate to the operating position, it is necessary to fold this extension to the collar front wall. The edge band that faces upward when the hinge plate is in this position is bonded to the inside of the outer pack by adhesive.

  The object of the present invention is to further develop a pack of the above-described configuration, especially for cigarettes, so that it can be produced by widely used packaging machines. Therefore, the problem underlying the present invention is to configure the outer pack and / or inner part blanks to be compatible with the packaging machine.

  In order to solve this problem, in the pack according to the present invention, the hinge plate or the coupling plate is formed by a substantially U-shaped punched portion as a part of the inner pack or the inner wall (inner) front wall. The outer side of the free segment on the end side facing the upper surface or the upper end wall of the slab is fixed to the inner side of the outer front wall, in particular by adhesion.

  Thus, the present invention avoids folding this plate or portion as an intermediate step during the manufacture of the pack, based on the arrangement and configuration of the coupling plate or hinge plate. Instead, in the present invention, an inner pack or a separate inner part is manufactured in the first working step and attached to the contents of the pack, i.e. the cigarette block, or folded around it. This formed internal unit is encased in the second working step by an outer pack blank. These wrapping steps are advantageously carried out with folding turrets of substantially conventional construction, which are continuous or connected to each other. Coupling means, i.e., adhesive, is applied to the outer surface of the hinge plate so that when the blank for the outer pack is folded, the outer pack is coupled to the hinge plate without any additional work steps.

  Another unique feature of the present invention is that the inner pack surrounds the pack contents at least in the front region, the rear region and the bottom region, and preferably further has a side wall consisting of overlapping inner side tabs. The inner pack is substantially cup-shaped, and the inner front wall of the inner pack preferably functions as a (normal) collar portion of a box-type pack with a lid. The inner pack and the outer pack are coupled to each other in the region of the rear wall, that is, the region of the inner rear wall and the outer rear wall, and in particular, are coupled by bonding in the upper end surface side and the lower bottom surface region. Yes. A lateral ridge line on the rear wall side of the outer bottom wall forms a linear hinge for swinging the partial pack of the outer pack.

  Another unique feature of the present invention is that the inner part is configured in a collar shape, not an inner pack, and this inner part is preferably provided with two juxtaposed coupling plates or hinge plates. is there. A bridge is formed in the center between these coupling plates or hinge plates in order to stabilize the inner wall or the front wall of the collar.

  Other features and uniqueness of the present invention will be described in detail below with reference to the drawings.

It is the figure which expanded and showed the longitudinal direction cross section along the cut surface XV-XV of FIG. 13 about the pack shown by FIG. It is a figure similar to FIG. 15 which shows the various opening steps and closing steps of this pack. FIG. 11 is a perspective view showing an opened state of the pack having the configuration shown in FIGS. 1 to 10, and shows a cut surface corresponding to FIG. 8. FIG. 17 is a view similar to FIG. 17 regarding the embodiment according to FIGS. 11 to 16, and shows a cut surface corresponding to FIG. It is the perspective view which looked at the outer front wall in the open position.

  The rectangular parallelepiped pack shown as an Example is used in order to accommodate the cigarette 10 as a pack content. Typically, the cigarettes 10 are bundled as a cigarette group 11 and surrounded by an inner blank 12 made of paper, tin foil or the like to form a cigarette block 13.

  The pack for housing the cigarette block 13 is composed of at least two pack parts, that is, an inner part and an outer part. The external portion is configured as an outer pack 14 that widely surrounds the pack contents. In the case of the embodiment according to FIGS. 1 to 10, the inner part is configured as an inner pack 15 and is partly or entirely surrounded by the outer pack 14.

  FIG. 1 shows the blank for the outer pack 14 open, with the areas for the outer front wall 16, the adjacent outer bottom wall 17 and the outer rear wall 18 continuing in the longitudinal direction. An inner tab 19 is provided at the free end of the outer rear wall 18, and an upper end wall 20 is provided on the outer front wall 16 so as to face the inner tab 19. On both sides of the outer front wall 16 and the outer rear wall 18, folding tabs, that is, outer side tabs 22 and 23 are further provided. The outer wall 21 of the outer pack 14 is formed. However, the outer side tabs 22 and 23 assigned to each other are not bonded to each other by bonding, and can be freely moved relative to each other.

  Side edge tabs 24 are provided on the upper end wall 20. Oppositely, an upper end edge tab 25 is provided on an extended portion of the outer side tab 23. In addition, a bottom edge tab 26 is provided on the extension of the outer bottom wall 17.

  The outer pack 14 formed from the blank of FIG. 1 consists of two partial packs 27, 28. The front side partial pack 27 substantially contacts the outer front wall 16, the outer side tab 22 (folded laterally), the upper end wall 20 also folded laterally, and the inside of the outer side tab 22. Side edge tabs 24. These are connected to the outer side tab 22 when the box-shaped partial pack 27 is formed. Similarly, the bottom edge tab 26 is also coupled on the inside to the outer side tab 22 and is therefore part of the front side partial pack 27. Accordingly, the rear partial pack 28 comprises the outer rear wall 18, the bent outer site tab 23, the laterally facing inner tab 19, and the upper edge tab 25. The upper edge tab is bonded to the inner tab 19 on the inside by adhesive. The outer bottom wall 17 is connected to the partial pack 28 via a hinge, that is, via a lateral bottom end 29. Accordingly, the two partial packs 27 and 28 can swing with respect to each other about the bottom end portion 29 (FIG. 8).

  The outer pack 14, particularly the front side partial pack 27, cooperates with the inner portion. In the case of the embodiment according to FIGS. 1 to 10, this inner part is configured as an inner pack 15, for example, using the blank shown in FIG. 2. In this blank, the pack contents, that is, the cigarette group 11 or the cigarette block 13 are surrounded by the inner pack 15 in a wide range, that is, except for the area of the upper front surface and the upper end surface. The blank of the inner pack 15 includes an inner front wall 31, an inner bottom wall 32 adjacent in the longitudinal direction, and an inner rear wall 33 that follows the inner bottom wall 32. The inner side wall 34 of the inner pack 15 includes bending tabs provided on the sides of the inner front wall 31 and the inner rear wall 33, that is, an inner side tab 35 and an inner side tab 36. These side tabs overlap each other and are connected to each other when the inner wall 34 is formed. The side tab 35 of the front wall 31 is located outside.

  The inner pack 15 is configured as a cup-shaped pack (hard cup) based on the shape of the blank. The inner rear wall 33 extends (almost) the full height of the pack or the full height of the pack contents. The size and shape of the inner front wall 31 are configured in the same manner as the collar portion that is normal in the case of a box-type pack with a lid, including the inner side tabs 35. This includes a side collar end 37 that is receded downward. Furthermore, the inner side tab 35 is provided with a tapered projecting portion 38, and this projecting portion forms a transition portion from the inner front wall 31 to the inner rear wall 33 in the region of the inner wall 34. A concave portion 62 is provided at the end of the inner side tab 36 so as to face the protruding portion 38 defined by the corrugated end portion. The recess has a shape and size that match the protrusion 38. Further, the contour of the collar end portion 37 is also provided so as to coincide with the opposite side of the inner rear wall 33, so that the blank for the inner pack 15 is shown in FIG. 2 from the continuous material web. The entire width can be cut without cutting waste.

  The inner pack 15 becomes (block-shaped) pack contents for the outer pack 14 when the blanks shown in FIGS. 1 and 2 are fitted. The inner pack 15 is completely accommodated in the outer pack 14. Further, the two packs 14 and 15 are coupled to each other, and are coupled to each other through the adhesive coupling portion 39 between the rear pack region, that is, the outer rear wall 18 and the inner rear wall 33. The adhesive joint 39 is provided on the upper end surface side region on the one hand and in the lower bottom surface region on the other hand. In a state where the pack is opened, that is, in a state where the partial pack 27 is pulled up, the pack contents are exposed in the upper end face side and front side areas, and the cigarette 10 can be taken out (FIG. 8).

  The open position of the pack, that is, the expanded position of the partial packs 27 and 28 is defined, and is further defined by a holding plate or hinge plate 40 as a coupling member between the inner pack 15 and the outer pack 14. . The hinge plate 40 is provided in the region of the inner front wall 31 or a partial region of the inner front wall in the inner pack 15, and the inner side is coupled to the outer front wall 16.

  In the case of the embodiment according to FIGS. 1 to 10, a suitable U-shaped punching portion having a punching edge 41 in the region of the bent end portion or the pack end portion formed between the inner side tab 35 and the inner front wall 31 is used. On the basis, the hinge plate 40 extends over the entire width of the front wall 31. The punched side 41 extends substantially to the central region of the inner front wall 31 and ends with a space from the inner bottom wall 32. The transverse arc-shaped punched portion 42 extends from the boundary line of the upper end surface of the inner front wall 31 or from the collar end portion 37 at a clear interval to form a lateral bridge 43.

  The hinge plate 40 is divided into two segments 46 and 47 by two parallel hinge lines 44 and 45. The outer terminating segment 47 is coupled to the outer pack 14. The segment 47 is preferably bonded to the inside of the outer front wall 16 by bonding the entire surface (FIGS. 7 and 8). When opening and closing the pack, that is, when the partial pack 27 swings, the hinge plate 40 acts particularly effectively based on the dimensions and arrangement of the hinge plate. At the start of the opening movement, the hinge plate 40 is lifted from its initial position in the inner front wall 31, while the segments 46, 47 are swung relative to each other by the hinges 44, 45. In the intermediate position (the chain line in FIG. 8), the free segment 46 assumes an arcuate posture due to the geometrical relationship, whereby elastic tension is accumulated in the hinge plate 40. This elastic tension first acts in the closing position direction, and then acts in the opening direction when the “dead center position” is overcome. When this is achieved, the segment 46 is in an extended position (FIG. 8). In the case of the closing movement, the steps are performed in the reverse order.

  In order to facilitate the opening process, the outer pack 14 is preferably provided with a circular opening 48 in the region of the outer front wall 16. Through this opening, an operating force by a finger can be transmitted to the inner pack 15 (FIGS. 7 and 8). Printing or graphics can be applied to the area of the opening 48 of the inner pack 15, i.e. the inner front wall 31, which is applied to the circular contour area of the lateral bridge 43, Visible from the outside when the pack is closed.

  Another uniqueness is the punching details for the hinge plate 40. Preferably, the parallel side punched edges 41 extend beyond the lateral hinge line 44 (FIG. 3). Thereby, the hinge line 44 functions freely and reliably when the hinge plate 40 swings. The hinge lines 44 and 45 can be defined by stamping and / or punching portions.

  In addition, uniqueness is applied to the area on the back of the pack. The outer rear wall 18 has a flap 49 defined by a tear line. This flap may extend over a large area of the outer rear wall 18, where a straight linear hinge 50 for the swingable flap 49 is provided at the straight pack end at the back of the pack. Preferably it extends into the region. The flap 49 cooperates with the printing of the graphic 51 and / or information on the inner rear wall 33 of the inner pack 15. When the flap 49 is opened, the figure 51 is visible. When the flap 49 is closed again, the tongue 52 can be inserted into the slit 53 of the inner rear wall 33.

  The embodiment according to FIGS. 11 to 19 is constructed in principle, that is to say in particular with regard to the arrangement and operation of the hinge plates 54, 55, in the same way as the previous embodiment. The outer pack 14 is inherited almost unchanged, but there is no flap 49 in the region of the outer rear wall 18. In other respects, the blank shown in FIG. 1 corresponds to the outer pack 14 of the embodiment shown in FIGS.

  In this embodiment, instead of using a substantially overall inner pack, a special inner portion 56 shown in FIG. 11 is provided. This inner part can be regarded as a collar part of a box with a lid because of its shape and function, that is, it consists of a collar front wall 57 and a color side tab 58. The blank configured in this manner is placed on the pack contents, that is, on the front side of the cigarette block 13 (FIG. 12), and the color side tab 58 is in contact with the side surface of the cigarette block 13. The blank or collar side tab 58 of the inner portion 56 extends to the bottom of the pack and is therefore supported on the outer bottom wall 17 when the pack is closed. The color side tab 58 is provided with a suitable edge-side support protrusion 59. On the side facing the support protrusion 59, a recess 62 exists in the area of the color side tab 58 with the same shape and size as the support protrusion 59. Also, the laterally facing upper collar end 63 coincides with the lower boundary of the collar front wall 57 so that the collar front wall can be cut from the continuous material web without cutting debris.

  In the region of the collar front wall 57, a coupling member with the outer pack 14 is provided. This is two juxtaposed hinge plates 54, 55, which are formed by a U-shaped punched portion as in the case of the hinge plate 40, and as in the case of the hinge plate 40, 60 is fixed in the collar front wall 57. The residual joint 60 is disconnected when the pack is first opened. The hinge plates 54 and 55 are divided into segments 46 and 47 by hinge lines 44 and 45. The segments 47 on the end sides of the hinge plates 54 and 55 are joined (by bonding) to the inside of the outer front wall 16 (FIGS. 15 and 16). The color side tabs 58 are connected (by bonding) to the outer pack 14 in the area of the outer side tab 23, ie to the partial pack 28 on the back side.

  The opening / closing process is performed in the same manner as in the above-described embodiment. This is also true for the elastic action of the hinge plates 54, 55 or segment 46. Both hinge plates 54, 55 are separated from each other by a longitudinal bridge 61, preferably located in the center, which ensures the stability of the inner part 56 of a relatively small area, especially when opening and closing the pack. The Another uniqueness of this blank shape, particularly the blank shape shown in FIG. 11, is that the lateral bridge 64 adjacent to the hinge line 44 is stabilized by the longitudinal bridge 61 despite the relatively small width. That is. Accordingly, it is possible to produce a blank 56 having a relatively small longitudinal dimension, ie a blank having a relatively thin lateral bridge 64. Sufficient shape stability is still guaranteed by the structure described above.

  In producing the pack described above, in the first folding mechanism, in particular the folding turret, it is advantageous if the blank of the inner pack 15 is folded in principle around the pack contents, ie around the cigarette block 13, in the usual manner. This completes the unit shown in FIG. 4 as an intermediate product. Next, the outer pack 14 is mounted by folding the blank shown in FIG. 1 around the inner pack 15 in a second folding mechanism, particularly a folding turret. Before the outer pack 14 is manufactured, adhesive is supplied to the hinge plates 40 or 54, 55, ie their segments 47 and / or to the outer front wall 16. During the folding process, the outer front wall 16 abuts the bonded location of the segment 47 (or vice versa), so that no special measures are taken between the hinge plates 40, 54, 55 and the outer pack 14. This will result in a coupling. The pack or the blank of the pack part is advantageously made of thin paperboard, as is usually found in the case of lidded boxes.
