초록 ▼

An apparatus for molding a tamper evident closure having a top, an annular skirt depending from the top, and a breakaway band secured to an underside of the skirt by a plurality of bridges includes a mold frame, a cavity portion releasably secured to the frame and configured for forming an outer surface of the closure, a core portion nestable into the cavity portion and mounted on the frame for reciprocal axial movement relative to the cavity portion, a slide portion mounted to the frame for reciprocal movement transverse to the axial movement of the core portion between a closed position and an open position, and a stripper device located on the frame for disengaging molded closures retained on the slide portion as the slide portion moves from the closed position to the open position.

An apparatus for molding a tamper evident closure having a top, an annular skirt depending from the top, and a breakaway band secured to an underside of the skirt by a plurality of bridges, said apparatus comprising: a mold frame; a cavity portion releasably secured to said frame, said cavity portion configured for forming an outer surface of the closure; a core portion nestable into said cavity portion and mounted on said frame for reciprocal axial movement relative to said cavity portion, said core portion configured for forming an inner surface and an underside of the top of the closure; a slide portion mounted to said frame for reciprocal movement transverse to said axial movement of said core portion between a closed position and an open position, said slide portion configured for forming a flange of the closure; said cavity portion, said core portion and said slide portion forming a molding cavity for forming the closure; said core portion, said cavity portion and said slide portion being oriented when said slide is in said closed position to form the closure as a molding substance is introduced thereto; said slide portion moves into said open position to allow the closure to disengage from said cavity portion and said core portion; and at least one stripper bar mounted to said frame in operational relationship to said slide portion and being substantially parallel with the direction of reciprocal travel of said slide portion, said stripper bar disengages molded closures retained on said slide portion as said slide portion moves from said closed position to said open position.
