Abstract
A cover device for a packaging container usable as a reclosable closure, comprising an outer layer provided with an easy opening device which has a grip and at least a tearing denotation extending circumferentially around the cover device. Additionally, the inner layer is attached to the outer layer at least at both sides of said tearing denotation. The inner layer is covered only partially by the outer layer, leaving a central portion of the inner layer exposed to the environment. A grip in the shape of a pull-ring is arranged in said central portion, and a strip-shaped connection portion connects the ring to a relatively narrow strip-shaped part of the outer layer, said part being removable together with the inner layer along a line defined by said circumferential tearing denotation. Of course, such tearing and removing facility necessitates that the tearing strength of the inner layer is lower than the weld strength and that the tearing denotation has a proper strength and is well-defined.
