  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The embodiment of the pack (for cigarettes) described in the drawings relates to a hinged box. This type of pack comprises an inner wrapping member 10 that encloses the pack contents, ie, a group of cigarettes 11 in which a plurality of cigarettes 12 are arranged. The inner packaging member 10 is formed of a thin packaging material such as tin foil, aluminum foil, or paper (printed or coated). The tobacco group 11 is completely surrounded by the inner packaging member 11 so as to form a tobacco block 13.

  The tobacco block 13 basically formed in a rectangular parallelepiped shape is accommodated in an outer pack (in this embodiment, a box 14 with a hinge lid) as a pack unit. In addition, the cigarette block 13 is usually formed of thin cardboard, and forms a lower box portion 15 and a lid 16. Here, the box portion 15 and the lid 16 are integrally coupled to each other at a linear coupling portion (hinge-like portion) 17 on the back side.

  Further, the box part 15 forms a box front part 18, a box rear part 19 and a box side part 20. Similarly, the lid 16 also has a lid front part 21, a lid rear part 22, a lid side part 23 and a lid side part 23. A lid upper surface portion 24 is formed. Further, a collar 25 is provided in the box portion 15, and the collar 25 is coupled to the box portion 15 on the inner side at the box front surface portion 18 and / or the box side surface portion 20. A part of the collar 25 protruding from the box portion 15 is surrounded by the lid 16 in the closed state of the pack. Further, the collar 25 is provided with a concave portion 26 on the front side thereof, and the concave portion 26 makes it easy to take out the pack contents.

  Thus, the pack includes a take-out assisting mechanism for the cigarette 12, and this take-out assisting mechanism is a lifting means for lifting at least one cigarette 12, and specifically, a plurality (three in this case) of cigarettes. A lifting strip 27 arranged and formed to allow 12 to be raised and gripped.

  The lifting strip 27 is a part of the inner enclosure member or the inner packaging member 10 and forms an inner front surface portion 28, an inner bottom surface portion 29, and an inner rear surface portion 30, as shown in FIGS. Here, flaps constituting the inner upper surface portion 31 are formed in the free end regions of the inner front surface portion 28 and the inner rear surface portion 30, and the flaps partially overlap each other on the inner upper surface portion 31 (trapezoidal shape). ) Longitudinal flap portions 32 and 33 are formed.

  The lifting strip 27 extends in the longitudinal direction of the inner packaging member 10, particularly at the center of the inner packaging member 10, and is laterally delimited by at least two particularly parallel broken lines 34, 35. . These broken lines 34 and 35 are formed such that when the end of the lifting strip 27 is gripped, the connection with the inner packaging member 10 is released and the lifting strip 27 functions as an automatic operating mechanism.

  In addition, the width | variety of the lifting strip 27 can be set variously, and is set here so that the three cigarettes 12 juxtaposed on the front side may be lifted. Further, as shown in FIGS. 7 and 9, the broken line portions 34 and 35 extend over the entire length or the entire height of the inner front surface portion 28 and the inner bottom surface portion 29 and a part of the inner rear surface portion 30.

  The lifting strip 27 formed of the material of the inner wrapping member 10 is provided with a reinforcing portion particularly against a tensile load, and in the present embodiment, this reinforcing portion is at least the entire length of the inner wrapping member 10 in the range of the lifting strip 27. It consists of a reinforcing strip 36 extending over. The reinforcing strip 36 is made of synthetic resin, and is fixed to the inner packaging member 10 by adhesion (or heat welding). Here, it is desirable to fix the reinforcing strip 36 to the outside of the inner wrapping member 10 so as not to come into contact with tobacco that is easily damaged. The reinforcing strip 36 is semi-permanently coupled to the inner packaging member 10 over the entire length of the inner packaging member 10 in a self-adhesive manner.

  The take-out assisting mechanism constituted by the reinforced lifting strip 27 is provided on the front side or rear side (back side) of the cigarette block 13, but in FIG. 1 to FIG. 3, FIG. 7 and FIG. The unit 28 is provided. The take-out assist mechanism further includes a known pull-out flap or flap 37. The flap 37 is divided into an upper portion of the inner front surface portion 28 and an adjacent side flap portion by a broken line portion 38 extending in the lateral direction. Has been. And by grasping | ascertaining the front side longitudinal direction flap part 32, the flap 37 will be pulled out at the time of opening | closing of the cover 16 (FIG. 2), and the upper part of the front side tobacco 12 will be open | released.

  The lifting strip 27 extends to the flap 37, and the lower portion of the inner upper surface portion 31 is the end (FIG. 7). Further, the end portion of the lifting strip 27 is partitioned by the flap 37 by the separating portion 39. In order to form the end of the lifting strip 27 as a tongue-like grip end 40, the separating part 39 is here formed in an arcuate shape. Further, the reinforcing strip 36 provided over the entire length is separated by the separating portion 39 so that a portion of the reinforcing strip 36 located in the longitudinal direction flap portion 32 is separated together with the flap 37. Therefore, the grip end 40 is exposed to the recess 26 in the collar 25 (FIG. 2).

  Alternatively (or in addition), lifting means may be provided on the back side of the pack. In the embodiment shown in FIGS. 4 to 6, the lifting strip 27 extends over the entire length of the longitudinal flap portion 33 in the inner back surface portion 30 and the inner upper surface portion 31 connected thereto. Further, a part of the grip end 40 defined by the arcuate separation part 39 protrudes from the longitudinal flap part 33 based on the separation part showing only the outline when the inner packaging member 10 is separated from the material strip. . Thereby, in the other side, ie, the longitudinal direction flap part 32, the recessed part 41 is formed. The broken line portions 34 and 35 that delimit the lifting strip 27 extend over part of the longitudinal flap portion 33, the inner back surface portion 30, the inner bottom surface portion 29, and the inner front surface portion 28. Further, the reinforcing strip 36 extends from the tongue-shaped grip end 40 to the recess 42.

  In order to operate the take-out assist mechanism according to such an embodiment, the flap 37 is removed (FIG. 4). Thereby, the longitudinal direction flap part 33 of the back side is exposed in an upper surface part. Then, it becomes possible to grip the lifting strip 27 at the grip end 40 and pull it upward.

  In the simplest embodiment, the front lifting strip 27 has an arcuate separation 39 and broken lines 34, 35 to form a residual connection 42 of material, as shown in FIG. It is formed so that a gap is generated between them. This residual connection 42 is separated when the flap 37 is pulled apart to form a tongue-like end or grip end 40 of the lifting strip 27 as shown in FIG. 7 or 2 or 3. ing.

  FIG. 10 shows another embodiment in which the lifting strip 27 shown in FIG. 8 is provided on the back side. Here, the end of the lifting strip 27 in the longitudinal flap portion 33 is formed linearly. Has been. The flap or longitudinal flap 33 of the inner top surface 31 shows the marked end of the lifting strip 27 or the marked grip end 40 in this embodiment after the flap has been removed.

  The lifting strip 27 or the reinforcing strip 36 is marked with a marker that indicates the direction of tension to the consumer. In the present embodiment, this marker is indicated by an arrow 43 on the reinforcing strip 36. Moreover, since the broken line portions 34 and 35 have a cut extending in the longitudinal direction as the residual connection portion 44, a large force is not required to separate the lifting strip 27. Further, the separating portion 39 extending in the lateral direction forms an intersecting portion at the end portions of the broken line portions 34 and 35 as in the embodiment shown in FIGS.

  When the inner packaging member 10 having the lifting strip 27 and the reinforcing strip 36 are processed, the reinforcing strip 36 as the material strip to be connected is first attached to the material web 45 of each pack material, and then the broken line indicating the lifting strip 27. A part is formed, and finally a separation part for separating the inner packaging member 10 is formed.

  Such processing steps are integrated into the operation process of the packaging machine shown in FIGS. This packaging machine is used here for the production of hinged boxes.

  In the packaging station 46, a color reel 47 for manufacturing the collar 26, that is, a web of thin cardboard is wound, which is arranged below the packaging station 46. The color reel 47 includes the tobacco group 11 and the tobacco. It is provided below the tobacco conveyance path 48 that conveys the block 13. Further, an inner reel 49 is disposed above the cigarette transport path 48, and the material web 45 is drawn out from the inner reel 49. This material web 45 passes through the joining device 50 and then to a bonding station 51 for bonding to the strip web 52 to form a reinforcing strip. Here, the strip web 52 is pulled out from the strip reel 53.

  Further, the bonding station 51 is constituted by a guide roller 54 for the material web 45, and the material web 45 can be turned about 180 °. The strip web 52 comes into contact with the outside of the material web 45 by suitable guides of the strip web 52 by the guide rollers 55 arranged alternately at this turning point.

  The unit consisting of the material web 45 and the strip web 52 is fed to a pressing device having at least two opposingly arranged pressing rollers 56, 57. This pressing device presses the material web 45 during conveyance and connects it to the strip web 52. Further, it is conceivable that the pressing roller 56, which is one of the pressing rollers, is an embossing roller for embossing the material web 45 particularly in the case of a tin foil or an aluminum foil. This embossing is also applied to the strip web 52.

  The webs 45, 52 thus treated reach the cutting station 58, and first, the broken line portions 34, 35 extending in the longitudinal direction of the material web 45 for defining the longitudinal direction of the lifting strip 27 cooperate with the cutter roller 60. It is formed by a working longitudinal cutter 59. Thereafter, a flap 37 including a broken line part for defining the grip end 40, that is, a horizontal separating part for defining the broken line part 38, that is, a separating part 39 is formed by a vertical cutter 61 appropriately formed. . Finally, in order to separate the treated inner packaging member 10 from the material web 45 from the material web 45 by the cutter 62, a transverse separation is formed across the material web 45. And the inner packaging member 10 is prepared for the subsequent rotating suction disk 63 for the tobacco group 11 conveyed perpendicularly to the surface of the inner packaging member 10.
