Abstract

A machine for automatic sealing of sterile bottles in a bottle filling plant is proved enabling high capacity. The machine has fluid powered means to axially displace a die forming means between a position above said bottle and a position surrounding a cap in the bottle mouth. Telescopically displaceable means are also provided to close said die forming means radially around the neck of said bottle and, after execution of said sealing, to open said die forming means radially. The machine also includes telescopically displaceable plunger means to apply axial pressure towards the top of the cap pressing it down into the die forming tool against the action of a resilient plug in the mouth of the bottle.
