Abstract
A pack provided with: a group of tobacco articles; and a sealed wrap, which encloses the group of tobacco articles, has a pull-out opening for the tobacco articles, has an inner pressure that is different from the atmospheric pressure, and consists of a heat-sealable sheet of wrapping material, which is folded around the group of tobacco articles and is stabilized by means of heat-sealing.
Claims8
Pack (1) comprising:
- a group (4) of tobacco articles;
- a sealed wrap (3), which has an inner pressure that is different from the atmospheric pressure, encloses the group (4) of tobacco articles, has a pull-out opening (5) for the tobacco articles and consists of a heat-sealable sheet (14) of wrapping material, which is folded around the group (4) of tobacco articles and is stabilized by means of heat-sealing;
- and
- a rigid reinforcement element (10), which is arranged on the inside of the sealed wrap (3) in contact with the group (4) of tobacco articles and embraces the group (4) of said tobacco articles;
- the pack (1) is characterized in that at least a portion of the sealed wrap (3) is mechanically coupled, by means of glueing or heat-sealing, to a corresponding portion of the reinforcement element (10).

A wrapping method to manufacture a pack (1) for tobacco articles comprising a sealed wrap (3);
- the wrapping method comprising the steps of:
- folding a heat-sealable sheet (14) of wrapping material around a group (4) of tobacco articles to obtain the wrap (3);
- heat-sealing overlapping portions of the sheet (14) of wrapping material to stabilize and seal the wrap (3);
- folding a reinforcement element (10) around the group (4) of tobacco articles before folding the sheet (14) of wrapping material around the group (4) of tobacco articles;
- and
- changing the inner pressure of the sealed wrap (3), in order to cause the sealed wrap (3) to have an inner pressure that is different from the atmospheric pressure;
- the wrapping method is characterized in that it comprises the further step of mechanically coupling, by means of glueing or heat-sealing, at least a portion of the sealed wrap (3) to a corresponding portion of the reinforcement element (10).
