Abstract: In the case of a process for producing a two-chamber pressure-package (R) an inner body (2) of fold-forming, respectively crumplable, material is connected with an outer casing (1) in the area of an adhesive layer (3). Then outer casing (1), adhesive layer (3) and inner body (2) together form a bead (7) around an opening (13). However, a ring (14) is removed from the outer casing before the bead (7) is formed.
