Abstract: A vacuum canister includes a storage space and a removable lid. The lid includes a pump housing that defines a pumping chamber within which a sliding piston is disposed. The piston is connected to a handle via a piston rod and features a skirt-like piston valve that seals against the side wall of the pump housing when the piston travels downward but permits air to pass when the piston travels upward. Air is pumped from the canister storage space via the pump. A vacuum indicator and release valve are also positioned in the lid. A bellows communicates with the canister storage space and contracts when a vacuum is present. The bellows is connected to a lever which pivots to extend a button indicating the presence of the vacuum. Pushing the button causes the lever to engage a vacuum release valve.
