Abstract
Abstract The invention pertains to a perforating and sealing device for carbon dioxide capsules and suchlike, it comprises a capsule support; in this support is a bore for an axially movable piston, for the purpose of capping the collar of the capsule; the piston is provided with an axial passage; a perforating element extends partially into that passage and is movable toward the capsule until the latter is perforated, the piston being then firmly pressed against the capsule by the gas pressure in the bore.
