Abstract

ABSTRACT A mold for making a plastic pilfer-proof cap having frangible members connecting the pilfer-proof ring to the skirt of the cap and in axial alignment therewith and having sufficient strength to permit flexing under axial compression but to break when flexed while under tension. The mold includes inner male and outer female members for forming the mold therebetween. The female member includes radially movable rams for engaging the male member to define the mold space for forming the frangible members of the cap.
