Abstract
For the molding of bottle caps having irregular lower boundaries, such as caps having depending tabs, the conventional mold has a core and a surrounding sleeve in which the core slides. This is modified by using a split sleeve which is maintained in close contact with the core during molding, but whose elements are freed to move outwardly away from the core when the mold begins to open. This solves the prior art problem of the galling of the contacting surfaces of sleeve and core.
