ABSTRACT:
Through a centrally placed ingot there is formed an injection moulded cover or end closure for a packaging container comprising at least an outer layer and an easy opening device formed therein, the device having a grip and a tearing denotation starting therefrom. The tearing device includes a first tearing denotation which merges into a circumferential tearing denotation extending inwardly adjacent the periphery of the outer layer and a second tearing denotation spaced from said first tearing denotation and spaced inwardly of said circumferential tearing denotation and extending in a generally spiral shaped path. These tearing denotations, together with a blind groove, define a wide material flow region and several material flow passages through which injected material will flow when exiting the centrally placed ingot. The injected material is channeled out of the material flow regions through the material flow passages in such a way as to form an easily openable container end closure with a tearing device having sharp, well-defined edges.
