subject: We Dedicate To Cap Mould [print this page] A cap mould for forming by injection molding a closure cap including an end panel and a cylindrical body, said cylindrical body having a free end and an integral interrupted internalthread about a major portion of said body; said mold comprising a core for defining internal surfaces of the closure cap and including thread forming means for forming said integral thread, said core having an end and a circumferential portion free ofthread forming means defining an interruption of the thread forming means, opposing first and second mold members having an irregular parting line, said first mold member having received therein said core for relative movement axially of said core, saidcore projecting above a portion of said parting line with said first mold member along said parting line portion defining said free end of the closure cap body, said first cap mould member also having one wall portion opposing that circumferential portion ofsaid core free of thread forming means defining said interruption of the thread forming means aand further defining a part of an exterior wall of the closure cap body, and said second mold member having a wall opposing said core and forming the remainderof the exterior wall of the closure cap body and a wall opposing said core end to form the end panel of the closure cap; said first and second mold members being separable along said parting line to separate said second mold member from a molded cap tofree that portion of a molded closure cap having an internal thread, and said first mold member thereafter being movable relative to said core to strip the molded closure cap from said core with the separation of the molded cap from the first mold memberbeing automatic. With the above and other objects in view that will hereinafter appear, the nature of the cap mould will be more clearly understood by reference to the following detailed description, the appended claims, and the several views illustrated in theaccompanying drawings.
Although only a preferred embodiment of the cap mould has been specifically illustrated and described herein, it is to be understood that minor variations may be made in the mold and more particularly the closure cap defining cavity of the moldwithout departing from the spirit and scope of the invention as defined by the appended claims.
