Technical Examples

A collapsible container for retaining and disposing liquids is described. The container includes an expandable liquid retaining portion and an inflatable top ring. As liquid, such as used motor oil, pours into the expandable liquid retaining portion the inflated top ring floats on top of the liquid as the liquid retaining portion expands. A top cover, which may be formed by flexible flaps with zip lock closures, may be included to seal the container for transport. A drain hole may be provided through a bottom portion of the container to drain the liquid out of the container. A handle may be provided to facilitate carrying the container filled with oil.
