OG exemplary drawing
 
1. A pack (1) comprising:
at least one product (2);
a blister (3) provided with a pocket (4), which houses the at least one product (2) and has an open end surrounded by a flat edge (5), and provided with a closing tab (6), which is connected to the flat edge (5) of the pocket (4) in order to close the open end; and
a support body (7), which houses the blister (3) in a sliding manner so as to allow the blister (3) to move relative to the support body (7) between a closing position, in which the at least one product (2) cannot be removed from the pocket (4), and an extraction position, in which the at least one product (2) can be removed from the pocket (4);
wherein a connection end (8) of the closing tab (6) is fixed to the support body (7) in a permanent and inseparable manner so that the sliding movement of the blister (3) relative to the support body (7) from the closing position to the extraction position causes a progressive separation of the closing tab (6) from the flat edge (5) of the pocket (4);
wherein the support body (7) comprises an upper wall (13) and a lower wall (14) overlapping one another so as to define, between them, an inner space which is partially occupied by the edge (5) of the pocket (4);
wherein the upper wall (13) has a first through opening (15), which is engaged by the pocket (4) and has a larger size than the pocket (4) in a sliding direction, so as to allow the blister (3) to slide between the closing position and the extraction position.
 
12. A method to produce the pack (1) according to claim 1 and comprising the steps of:
manufacturing the blister (3) provided with the pocket (4) housing the at least one product (2) and with the closing tab (6);
providing a flat blank (20) to form the lower wall (14) and the upper wall (13), which are hinged to one another; applying an adhesive at least on the lower wall (14);
laying the blister (3) on the lower wall (14) causing the connection end (8) to adhere to the lower wall (14) by means of the adhesive; and
bending the upper wall (13) relative to the lower wall (14) so as to cause the upper wall (13) to come into contact with the lower wall (14), thus allowing the pocket (4) to go through the first through opening (15) of the upper wall (13).
