Abstract
A cap has a top wall and a skirt depending from the top wall. The skirt has two tabs depending therefrom. One tab may be employed to fracture the skirt along a circumferentially weakened first score of which the angle may be from 180.degree. to 250.degree. of the encircling expanse of the skirt. The other tab may be used to tear a portion of the skirt along a pair of radially weakened second scores and to bend the skirt at the inner end portions of those scores, and to introduce air into the container.
