ABSTRACT:
A can has two closed can ends, one of which is provided with a pull tab having a pull-up member connected to the pull tab. The pull tab can be torn away from the associated can end to form an opening by pulling up the pull-up member which is connected to the pull tab. The pull-up member includes a bottom portion and a tapered insert portion extending upwardly from the bottom portion. After the pull tab is detached from the can, the pull tab can be broken off from the pull-up member and the tapered insert portion can be used to snugly seal the opening in the can end.
