  • the reinforcement strip 8 is connected to the front wall 8 of the inner container 3 along a transverse folding line 62, it is folded by 180° (in the pack 1 for cigarettes) relative to the front wall 8 (i.e. relative to the panel 8’), and it lies and is glued against an inner surface of the front wall 8 of the inner container 3 (i.e. against the panel 8’).
  • the blank 52 comprises a pair of wings 11”, which are arranged on opposite sides of the panel 11’, are connected to the panel 11’ along the two longitudinal folding lines 61, and constitute part of the side walls 15 of the outer container 2.
  • the blank 52 comprises a pair of wings 15’, which are arranged on opposite sides of the panel 14’, are connected to the panel 14’ along the two longitudinal folding lines 61, constitute part of the side walls 15 of the outer container 2, and overlap and are glued to the corresponding wings 10’ to constitute the side walls 15 of the outer container 2.
  • Figure 18 shows each panel 15’ with a reinforcement panel already folded onto itself.
  • the blank 52 comprises a pair of wings 15”, which are arranged on opposite sides of the panel 12’, are connected to the panel 12’ along the two longitudinal folding lines 61, constitute part of the side walls 15 of the outer container 2, and overlap and are glued to the corresponding wings 15’ to constitute the side walls 15 of the outer container 2.
  • the blank 52 comprises a pair of wings 9’, which are arranged on opposite sides of the panel 8’, are connected to the panel 8’ along the two longitudinal folding lines 61, and constitute the side walls 9 of the inner container 3.
  • the wrap 4 is obtained by folding the heat- sealable wrap sheet 63, which is rectangular- shaped, is folded around the group 5 of smoking articles and once folded it is stabilized by heat-sealing (i.e., the overlapping portions of the wrap sheet 63 are stably connected to one another by heat- sealing).
  • the wrap sheet 63 has a “U”-shaped incision and defines the extraction opening 26 of the wrap 4.
  • the closing tab 27 completely covering the incision i.e. the extraction opening 26
  • the repositionable glue 28 that is pressure-sensitive (i.e. it does not dry) and that allows to separate the closing tab 27 from the wrap sheet 63 even after a long time and for several times, and consequently to join again the closing tab 27 to the wrap sheet 63 is interposed between the closing tab 27 and the wrap sheet 63.
  • the wrap 4 could be obtained by folding a sheet of paper material (for example a cardstock similar to that of the blank 52 of Figure 16).
  • the wrap 4 could be obtained by folding a foil sheet.
  • the pack 1 could comprise a stiffening element arranged fixed to the rear wall 21 of the wrap 4. This stiffening element has the function of providing a contrast to the user when moving the inner container 3 from the closed position to the open position by pressing in the area of the through opening 16 obtained on the rear wall 14 of the outer container 2.
  • the longitudinal and transverse corners are right; in alternative, the longitudinal and/or transverse comers may be rounded or bevelled.
  • the above described pack 1 for cigarettes has several advantages.
  • the pack 1 for cigarettes described above allows to obtain a simpler and easier management of the closing tab 27 during the entire process of making the pack 1.
  • the pack 1 described above allows to have the connection portion 30 already folded by 180° as an integral part of the closing tab 27, without incurring the previously described drawbacks. Therefore, it is necessary to coordinate a single element (i.e. the closing tab 27) that has no protruding/folded flaps to be managed, thus simplifying the structure of the machine.
  • connection portion 30 serves as an end flap necessary for applying the peeling force of the closing tab 27 to the opening of the inner container 3.
  • connection portion 30 is solely delimited by the separation line 40.
  • the presence of the separation line 40 with some (i.e., at least two) joining points allows the integrity of the closing tab 27 to be maintained throughout the manufacturing process, which is then broken (deliberately) when the inner container 3 is opened for the first time, thus defining the end flap and its functionality in a geometrically unambiguous manner.
  • the position of the glue 31A or 3 IB ensures that when the inner container 3 is opened to separate the two flaps 33 and 34, which slide one above the other to show the extraction opening 26 when the pack 1 is opened or to cover it when the pack 1 is covered.
  • the conformation of the folded closing tab 27 provides the advantage of having a constant thickness over at least 65% (i.e., about two-thirds) of the closing tab 27, ensuring a uniform wrapping of the tab reel and thus allowing its tensioning to be improved.
  • the percentage of constant thickness of the closing tab 27 up to 100%
  • the tensioning of the reel increases further.
  • the length of the folded closing tab 27 is the same as the width of its reel.
  • the stop member 46 allows the wrap 4 to be held stably in position in the inner container 3.
  • stop member 46 by making the stop member 46 with a blank 47 separated from the blank 52, it is possible to keep the latter blank 52 smaller and therefore easier to handle in the machine.
  • the stop member 46 being made separate from the outer container 2 and from the inner container 3 allows to adjust the height of application of the same on the wrap 4 so as to balance more the torque applied by the user through his/her finger by pressing against the inner container 3 of the pack 1.
