This invention relates to self-contained self-storing opening means for hollow containers such as thin-walled metal beverage cans customarily provided with attached opening means therefor arranged to be or able to be pulled loose from the can and discarded hazardously underfoot and typically featuring an opening therethrough with a hazardous raw metal edge. This invention provides a can cover including a flap portion and a pull tab, respectively having first and second mating portions mutually fixedly interfitted and permanently interconnected, located either fixedly in the cover or together rotatable with the flap portion inwardly of the can as it is opened, the pull tab having an annular end portion encircling the opening formed by breaking open the flap portion and covering the raw edge of this opening in its final protective position. Accordingly, the present invention is useful on beverage cans and other hollow containers needing non-hazardous permanently attached opening means.
