ABSTRACT:
An injection-molded plastic container or closure has a sidewall extending from a base wall to a rim wall. An upper portion of a segment of the rim wall extends with both outward and inward directional components. A lower portion of the given segment extends with both downward and inward directional components; and at a given level of the lower portion, the given segment has an inner surface and an outer surface that each extend with downward and inward directional components. At the given level the inner surface and the outer surface of the lower portion are respectively formed by different mold components of one of the mold parts. Upon removal of the container or closure from the mold parts, the inner surface and the outer surface of the lower portion at the given level of the given segment are contemporaneously removed from one of the separated mold parts.
