Claim 6:
7. An apparatus for modified atmosphere packaging comprising:
a vacuum pump interconnected to a port;
a receiver configured to interconnect to at least one gas-filled canister;
the receiver comprises a valve configured to control release of pressurized gas;
the valve interconnected with the port of the apparatus,
wherein interconnection of an outlet end of the at least one gas-filled canister to the receiver and actuation of the valve results in flow of the pressurized gas through the valve and through the port of the apparatus, wherein pulling of a vacuum with the vacuum pump results in pulling of the vacuum through the port of the apparatus;, the valve comprises a cam constrained to the valve by a pivot, the cam having an extension arm on a first side of the pivot, and a lobe on a second side of the pivot; and
the valve further comprises a spring-loaded follower adjacent to the lobe, wherein the spring-loaded follower is interconnected with the at least one gas-filled canister;
wherein rotation of the cam in a first direction results in the lobe depressing the spring-loaded follower, and
wherein the spring-loaded follower is configured to release the pressurized gas from the at least one gas-filled canister interconnected with the receiver when the spring-loaded follower is depressed.
