Abstract
Abstract A lid for beverage cans and the like is provided with a circular opening, the opening being formed so as to have an inwardly extending tapered peripheral wall, the innermost edge of which may be flared laterally to form a skirt. The diameter of the opening is less at the outermost than at the innermost edge of the wall. A similarly tapered plug is fitted tightly, from inward to outward in this opening, and may have an enlarged skirt portion which engages the skirt of the opening in a sealing relationship. The plug, therefore, has a maximum diameter which is greater than the diameter of the opening. The outer part of the plug has a raised table portion along part of its circumference to create leverage when the plug is dislodged by pushing inwardly on the table portion.
