Abstract

Blister pack for pharmaceuticals containing a base with a plurality of recesses which are surrounded by a shoulder. A lid foil is attached to the shoulders. Removable contents such as a tablet, capsules or ampoules reside in each of the recesses and may be removed therefrom by pressing the recess in question and penetrating the lid foil or by removing the lid foil over the recess. The blister pack features a movable lid or a clamping element which covers at least one recess, and the clamping element is arranged in such a manner that it can be slid over the lid foil, and the clamping element closes off again at least one recess, where the lid foil has been penetrated or peeled back, or closed again at least one recess which on filling was left unfilled and without lid.
