A hose direct canister lid (10) includes a port (22) that accepts a hose connected to a source of vacuum in order to evacuate a canister to which the lid is connected. The hose direct canister lid includes a first valve (50) for exposing the canister to the source of vacuum when the vacuum hose is secured to the lid, and wherein the first valve closes when the source of vacuum is removed in order to seal the lid and canister from ambient. The hose direct canister includes a second valve (39) used to break the vacuum and expose the interior of the canister to ambient.
