Abstract

A self-contained, self-closing toilet lid includes a water reservoir formed within an upper portion of the lid. When the lid is in its vertical closed position, water from the reservoir is allowed to trickle at a predetermined rate into an activation bucket positioned within a lower portion of the lid and pivotally coupled proximate an inner peripheral edge of the lid. When a sufficient volume of water has been gravitationally transferred from the upper water reservoir to the lower activation bucket, the weight of that transferred water causes the activation bucket to pivot, which in turn actuates a release mechanism that allows the lid to hingedly move to an off-center position, permitting it to fall to its horizonatal closed position. If both the toilet lid and the seat conventionally mounted behind it are in the open position, automatic closing of the lid will push the seat to the closed position also.
