ABSTRACT:
A self-closing container top adapted to be used in conjunction with a container having an upper rim defining an opening. The invention includes two generally horizontal top panels supportively held for rotation about opposing coaxial mounting shafts each having a horizontal axis therethrough. These top panels are arranged in opposing side-by-side arrangement wherein their center margins form a common parting line. Each axis of top panel rotation is positioned between the center margin and the outer panel margin such that self-righting means returns the top panels to a generally horizontal closed position over the container opening and against stops. The stops prevent the panels from rotating beyond a point where the top panel center margins, moving upwardly, begin to diverge. The self-righting means may be a counterweight connected near or at each outer margin, or spring bias means mounted about at least one mounting shaft. The invention may be provided in various forms wherein the top panels are separate and removable, wherein the top panels are connected to the container rim, or wherein the top panels are mounted within a perimeter frame which, in turn, is removably supported atop the rim of a container.
