ABSTRACT:
An essentially straight walled, minimally tapered or non-tapered container is provided with a radially outwardly projecting chime or bead formation which enables gripping of such container when molded to facilitate removal of the container from an injection mold apparatus. The described molded part extraction technology allows the formation of a novel easy-open closure in which the easy-openable closure structure is injection molded and may be one piece with a container side wall. The disclosure also includes a description of two forms of molding method and apparatus suitable for accomplishment of the described technology. The novel easy openable closure structure includes a closure panel forming a side wall which is inwardly convergent from one end of the container. A weakened web connects the closure panel to the container. The closure panel is provided with other weakened webs and a pull ring which enables removal of the closure panel by a pulling force exerted on the pull ring.
