1. Pressurized can comprising a body, a valve arranged in a dome, a base ( 16 ), an inner shell ( 1 ) with detachable, push-off type cover ( 8 ) arranged on the base ( 16 ) and a movable shaft ( 7 ) arranged in a fixing element ( 2 ) and extending through the base ( 16 ) into the inner shell ( 1 ) and serving as release element for the inner shell with said inner shell ( 1 ) being connected to the base ( 16 ) via the fixing element ( 2 ) characterized in that a piston element ( 3 ) movable in longitudinal direction of the inner shell ( 1 ) is arranged inside the inner shell ( 1 ), said piston element ( 3 ) yielding a sealing effect at the inner shell's ( 1 ) inner wall and interacting with the shaft ( 7 ) in such a manner that when the shaft ( 7 ) is moved into the inner shell ( 1 ) the piston element ( 3 ) causes a liquid present inside the inner shell ( 1 ) to be pressurized so that the cover ( 8 ) is forced off wherein the piston element ( 3 ) has a central recess ( 10 ) in which a can-side end ( 7 b ) of the shaft ( 7 ) is secured.
