ABSTRACT:
An internal cover (10) is used for enclosing the contents of a straight walled container (38) which consists of a disc shaped rigid body (20) having a recess (22) in the top surface creating a depression with an outside rim (24) extending around the edge and at least one valve air vent opening (30) within the recess. The body also has a circumferential groove (26) with a lip seal (36) disposed within the groove for sealing the cover to a container's side walls. A bail handle (40) is rotatably affixed within the body recess and has least one valve bore (44) therethrough covering at least one air vent opening forming a valve. When the handle is rotated to a vertical position an air flow path is created permitting the cover to be inserted into a container. When the cover is resting on top of the contents the valve is sealed by rotating the handle to a horizontal position.
