the radius of curvature, acting to limit the extent of permanent deformation of the corresponding projection during removal of the male mold portion so the projection can elastically return to substantially its xe2x80x9cas moldedxe2x80x9d configuration.
In a variation of the disclosed embodiment, the male mold portion comprises an inner core member, a skirt member and an outer core member. The resilient flexible projections of the closure are formed between a molding surface disposed on the outer core member and a molding surface disposed on the skirt member. Prior to the step of removing the male mold portion from the molded tamper-indicating closure, the method further includes the step of separating the molding surface disposed on the outer core member from the bottom surface of the closure projections.
In another variationof the disclosed embodiment, following the step of separating the molding surface of the outer core member from the bottom surface of the closure projections, the method further includes the step of separating the female mold portion from the molded tamper-indicating closure.
In another variation of the disclosed embodiment, the inner surface of the closure includes an integrally molded internal screw thread arranged for engagement with an external screw thread disposed on the inner core member. The mold assembly includes a stripper ring arranged to be positioned against the closure to resist rotational movement of the closure during removal of the male mold portion. Under this variation, the step of removing the male mold portion from the closure includes the sub-step of rotating the inner core member while utilizing
