The lid consists of two unitary parts both of which are molded from a soft rubbery substance. The body of the lid butts against the mouth of a container and includes a vacuum release valve and a check valve through which air may be evacuated from the container. The second part is a bellows pump that sealingly engages the body of the lid. As the bellows pump is worked manually, air is drawn from the container into the pump through the check valve on the body of the lid and the air is then discharged into the atmosphere through a second check valve that is an integral portion of the removable bellows pump. Because of its simplicity and lack of small parts, the lid is easy to clean effectively, and reuse is contemplated. The actuators for the pump and for the vacuum release valve extend to the periphery of the lid thereby making it easy for use by handicapped persons.
