Abstract:
1. A blister pack comprising a base foil ( 1 ) with at least one chamber ( 2 ) formed therein for receiving a product ( 2 a ), a rupture foil ( 3 ) disposed on said base foil ( 1 ) so as to close said at least one chamber ( 2 ), said rupture foil being firmly connected to the base foil ( 1 ) except for a limited area ( 5 ) which is delimited by a seal edge ( 6 ) along which the rupture foil is perforated, and a plastic foil ( 4 ) applied to the rupture foil ( 3 ) and being attached thereto with a retaining force which is smaller than the force with which the rupture foil ( 3 ) is attached to the base foil ( 1 ) so that, upon removal of the plastic foil and the rupture foil from the base foil in the area ( 5 ) where the rupture foil ( 3 ) is not attached to the base foil ( 1 ), the rupture foil breaks away when reaching the seal edge ( 6 ) whereby the chamber ( 2 ) remains securely covered by the rupture foil ( 3 ) while the plastic foil ( 4 ) is peeled off the rupture foil ( 3 ).
