## 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.

## Claims

### Claim 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).

### Claim 2 (depends on 1)

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).

### Claim 3 (depends on 1)

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).

### Claim 4 (depends on 1)

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).

### Claim 5 (depends on 1)

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).

### Claim 6

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).

### Claim 7 (depends on 6)

A wrapping method according to claim 6 and comprising the further steps of:
folding a blank around to the sealed wrap (3) to form a rigid outer container (2) which is cup-shaped and houses the sealed wrap (3); and
mechanically coupling, by means of glueing or heat-sealing, at least a portion of the sealed wrap (3) to a corresponding portion of the outer container (2).

### Claim 8 (depends on 6)

A wrapping method according to claim 6 and comprising the further step of heating the sealed wrap (3) after having finished making the sealed wrap (3), so as to obtain a heat-shrinking of the sealed wrap (3).
