Abstract
In a blister pack comprising a base foil with chambers formed therein for receiving a product sealed into the chambers, a rupture foil disposed on the base foil to close and seal the chambers and a plastic foil disposed on the rupture foil for the protection of the rupture foil, wherein the plastic foil is attached to the rupture foil with a retaining force which is lower than the force with which the rupture foil is attached to the base foil, except for a limited edge area of the rupture foil which is delimited by a seal edge and a perforation extending along the seal edge, so that, upon removal of the plastic foil and the rupture foil from the base foil in the limited edge area where the rupture foil is not attached to the base foil, the rupture foil breaks away from the plastic foil when reaching the perforated seal edge so that the chamber remains reliably covered by the rupture foil while the plastic foil is peeled off the rupture foil.
