ABSTRACT:
Disclosed is a plastic injection molded container and closure assembly wherein the closure has a plug-like section and an outer skirt. The plug-like section includes a vertical cylindrical wall having upper and lower annular nesting surfaces for nesting closures in a stack. An annular top wall outwardly extends from the vertical cylindrical wall upper end and a skirt depends downwardly from the outer periphery of the outer top wall. The lower free end of the skirt includes a bead defining a thick cross-sectional area on the skirt for engaging the upper flange of a container when mated therewith. The container upper flange extends outwardly and downwardly from the open end of the container and has a free end engaging the bead on the closure skirt. The container has a sealing lip of increased cross-sectional thickness at the container rim projecting radially inwardly into sealing engagement with the vertical cylindrical wall on the plug-like section.
