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.

Abstract: A mug (10), specifically a vessel (20) incorporating a plunger assembly (30), that includes a number of fingers (42), is improved by positioning the fingers downwardly to contact the side wall of the vessel. The improvement also includes the following; a minor diameter portion (58) of the vessel sized to fit a motor vehicle cup holder. An open distal ended liner (62) intimately embracing a storage container compartment (60) formed on an inside surface of the outer shell minor diameter portion of the vessel. A closure base (66) removably engages the liner and encloses the bottom of the vessels storage container compartment. The closure base includes a number of inwardly facing spacer legs (68) that removably retain a storage container (72) including a detachable lid (74). The storage container provides a receptacle for such items as coffee grinds, tea leaves, sugar and creamer etc. such that the items may be conveniently available with the mug.
