Abstract (en)
[origin: EP1059129A2] The twin-chamber pressure package, where one chamber holds the filled contents and the other chamber has the pressurized propellant, has a sealed beaded edge between the inner and outer containers (1,2). The inner container (2) has nominal distortion zones (25) to give a targeted collapse and prevent the formation of sharp edges or folds. The nominal distortion zones (25) are formed by the insertion of a tool spindle (11) into the inner container (2) to develop a pressure difference between its interior (7) and the propellant zone (8) and take up the contour shape of the tool spindle (11) by pressure or suction.
