A cap opening machine for a film seal cap, includes a hollow punch with a depressurizable space defined in a hollow portion thereof; a pressure regulating device for regulating pressure in the depressurizable space; and a punching-action causing mechanism for moving the punch and the cap relative to each other, whereby a punched-out piece, punched out by the punch, is processed by the action of a differential pressure between atmospheric pressure and the pressure in the depressurizable space. With the design, this cap opening machine can eliminate manual work of an operator that may cause infection, hardly contaminates the contents of containers, and shows high performance.
