ABSTRACT:
A container such as a beverage can has a flat top. An opening formed in the top has an inwardly reverted flange which prevents a sharp edge. The closure comprises an inside disc of a diameter greater than the diameter of the opening, and an outside button also of a diameter greater than that of the opening. The button has a raised dome like top, and the button and disc are joined by a narrow stem of a length such that both the button and disc tightly press against the can top and flange, respectively.
