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.

First claim

The invention claimed is:

1. 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 ).

2. A pack according to claim 1 , wherein:
the inner wrap ( 3 ) comprises an “open & close” sealing panel ( 6 ), which is glued to the sheet ( 14 ) of wrapping material by interposing a pressure-sensitive repositionable adhesive ( 16 ), normally adheres to the part of the sealed wrap ( 3 ) that is arranged around the pull-out opening ( 5 ) so as to close the extraction opening ( 5 ), and can be temporarily raised to free the pull-out opening ( 5 ); and
the presence of the pressure-sensitive repositionable adhesive ( 16 ) between the sealing panel ( 6 ) and the sheet ( 14 ) of wrapping material causes the permanent glueing of the portion of the sheet ( 14 ) of wrapping material enclosed by the incision ( 15 ) to the sealing panel ( 6 ), and causes a temporary glueing between the portion of the sheet ( 14 ) of wrapping material surrounding the incision ( 15 ) and the sealing panel ( 6 ) so as to normally keep the sealing panel ( 6 ) in contact with the sheet of wrapping material ( 14 ) to close the pull-out opening ( 5 ).

3. A pack according to claim 1 wherein the reinforcement element ( 10 ) is “U”-shaped and comprises a front wall ( 11 ) and a pair of lateral walls ( 12 ).

4. A pack according to claim 1 , wherein the reinforcement element ( 10 ) has a tubular shape and comprises a front wall ( 11 ), a rear wall, and a pair of lateral walls ( 12 ).

5. A pack according to claim 1 and comprising a rigid outer container ( 2 ) which is cup-shaped and houses the sealed wrap ( 3 ); wherein 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 outer container ( 2 ).
