  • FIG 13 With the number 1 there is shown as a whole an internal wrapping for a rigid packet of cigarettes preferably being made of cardboard or rigid cardboard and being shaped as a cup with a reclosable lid.
  • the internal wrapping 1 encloses a bundle of cigarettes 10 having a parallelepiped shape and it has an opening for extracting the cigarettes frontally and on the top, being defined by a weakening line 2.
  • the internal wrapping 1 when it encloses the bundle of cigarettes 10, has a rectangular parallelepiped shape having a top wall 3 and a bottom wall 4 being parallel and opposite to each other, two major lateral walls 5 and 6 being parallel and opposite to each other, and two minor lateral walls 7 being parallel and opposite to each other.
  • the opening of the internal wrapping 1 is centrally arranged and it is closed by a reusable closing label 8, which affects a portion of the front wall 5 of the wrapping 1 and a portion of the top wall 3 of the wrapping 1 , as well as possibly a portion of the back wall 6 of the wrapping 1.
  • the closing label 8 is fixed to the wrapping 1 by means of a repositionable adhesive that does not dry, which is applied to the lower surface (the one contacting the wrapping 1) of the closing label 8 and it is arranged all around the extraction opening to allow the closing label 8 to be partially separated from the wrapping 1 and then fixed again to the wrapping 1 more than once.
  • the closing label 8 is provided with a lower grasping tongue 8a, which is free of repositionable adhesive, rests on the front wall 5 of the wrapping 1 and is suitable to facilitate grasping the closing label 8 when lifting the closing label 8 itself; in other words, in order to lift the closing label 8, an user can easily grasp the grasping tongue 8a, which is not by any means fixed to the front wall 5 of the wrapping 1.
  • the wrapping 1 is obtained by folding a wrapping sheet 1 1 , which has a rectangular shape, it is made of airtight and heat-sealable plastic material, and it is folded around the bundle of cigarettes 10 according to the procedures being described in the following.
