Abstract: This relates to a mold for forming closure caps and like cap-like members having a peripheral body with internal threads. The mold is constructed to have an irregular parting line with the result that a major part of the body of the closure cap may be externally defined by that mold member which is moved to an out-of-the-way position when the mold is opened, leaving the injection molded closure cap body free for radial expansion and thus permissible stripping of the closure cap from the core about which it is molded. This construction eliminates the customary ejector sleeve and permits the base mold member to function as an ejector block for directly stripping the molded closure cap from the core. This construction permits mating tapered surfaces on the base mold member and the core which form a seal and do not have relative sliding contact, thereby eliminating previous undesired wear surfaces.

Abstract: This relates to the provision of latch mechanisms for a dispensing closure of the type having a well formed in the top wall thereof with the well being of a stepped bottom construction and there being a closure member which includes a hinge strap and a cover panel with the cover panel having an outline generally corresponding to that of the well and being divided by a transverse hinge line into a cover element and an opener. when the opener is depressed, the cover element automatically swings to an upstanding position uncovering a dispensing opening or openings. Latch mechanisms are provided to retain the opener within the well and to retain the cover element in an upstanding out-of-the-way dispensing position. This abstract is not to be construed as limiting the claims of the application.
