Vacuum Food Processor Canister Closure Valve

摘要

A vacuum food processor canister vacuum coupling assembly includes a canister closure defining a recess in a top portion of the closure. A valve stud within the recess defines an upper rim and a vacuum port extending through the closure. A vacuum valve plunger includes a valve stem extending through the vacuum port and defines a pliable upper peripheral flange to engage the rim of the valve stud to form a releasable seal. A vacuum coupler fitting is constructed to be manually press-fitted onto the valve stud to provide a press-fit seal therebetween to enable evacuation of air from a canister through the vacuum port. The press-fit seal can be maintained without manual support. The valve plunger can be displaced to release the vacuum. The valve plunger is positioned within the recess and the vacuum coupler fitting has sufficient clearance to avoid displacing the valve plunger during fitting removal.
