Claim:
A foil pocket ( 10 ) comprising at least one carrier foil ( 11 ), at least one covering foil ( 12 ), and a foil or sheet product ( 1 ) containing a pharmaceutically active substance, for adhering to a tissue surface, being enclosed in a gas-tight and moisture-tight manner by the carrier foil ( 11 ) and the covering foil ( 12 ), wherein: the contact between the carrier foil ( 11 ) and the covering foil ( 12 ) forms a joining zone ( 30 ), and the strength of the connection in the joining zone ( 30 ) being lower than the strength of the carrier foil ( 11 ) and covering foil ( 12 ) at least one joining-zone section ( 33 , 34 ; 43 , 44 ), which is not arranged transversely with respect to the tear-open peeling direction ( 9 ), is located laterally beside the product ( 1 ), narrows or widens transversely with respect to the tear-open peeling direction ( 9 ), at least in some sections, at least one additional joining zone ( 38 - 41 ) placed at a short distance from the corresponding joining-zone section ( 34 , 44 ) also counting as a widening, at least the first quarter of the joining-zone section ( 33 , 43 ) which is not arranged transversely with respect to the tear-open peeling direction ( 9 ) has no widening ( 35 - 41 ) or narrowing ( 55 - 58 ); and wherein when the at least one joining zone-section ( 33 , 34 ; 43 , 44 ) is torn open by a person in the tear-open peeling direction ( 9 ), the foil or sheet product ( 1 ) adheres to the tissue surface at an application point and does not contact the person outside the application point; and wherein the width of the joining zone ( 30 ) is narrowed and contains: i. a notch ( 55 ) which projects into the joining zone ( 30 ) from the outside of the foil pocket ( 10 ); or ii. a notch ( 56 ) which projects into the joining zone ( 30 ) from the inside of the foil pocket ( 10 ); or iii. a cutout ( 58 ) in the form of a slot which has a length which corresponds to the average width of the joining zone ( 30 ).
