Blister pack

Abstract

A blister pack comprises a bottom film and a top film for forming a plurality of film containers ( 1 ) that can be separated from one another by perforations ( 10 ), each having one accommodating chamber ( 2 ) for a filling, particularly a pharmaceutical active substance formulation, the accommodating chambers ( 2 ) being arranged around the peripheral boundary of the blister pack ( 7 ). The centre of the blister pack ( 7 ) is formed by a detachable film section ( 4 ), after the removal of which an opening region ( 5 ) is available for opening the accommodating chamber ( 2 ).
