Abstract

A blister package (1) with a bottom part (2) with at least one depression (3) and a cover film (6) that is fastened to the bottom part (2), covers the depressions (3) and can be forced through, the depressions (3) containing a product to be withdrawn. A cover layer (7) covers the cover film (6) and contains sections that can be forced through and others that cannot be forced through. The depression (3), in the rest position of the blister package (1), is located at least partially or completely above a section of the cover layer (7) that cannot be forced through. In order to expose the product to be withdrawn, the depression is displaced across a section (8) in the cover layer (7) that can be forced through by way of a lateral movement with respect to the cover layer (7). The product to be withdrawn can then be forced through the cover film (6) and the cover layer (7).
