Abstract
Abstract A container, such as a rubbish container, is adapted to secure a flexible plastic liner in an open position conforming to the shape of the container's interior. The securing of the flexible plastic liner is accomplished by the cooperation of the rim of the container about the periphery of which the edge of the flexible plastic liner is tightened forming an ear in the holder's hand and a notched member into which the ear is inserted to hold the flexible plastic liner securely in the proper position in the container.
