Abstract
A food processing container includes a food processing chamber and a cover assembly with a latch mechanism operable between latched and unlatched positions. The latch mechanism includes a first magnetic member disposed therein. An interlock assembly is disposed outside of and adjacent to the food processing chamber and includes a sealed cavity with a plunger member moveable disposed within the sealed cavity. The plunger is operable between at-rest and actuated positions within the sealed cavity and includes upper and lower magnetic members disposed at opposite ends of the plunger member. The plunger member moves to the actuated position as the latch mechanism moves to the latched position due to a repulsion force between the first magnetic member and the upper magnetic member, and further wherein the lower magnetic member moves into the lower portion of the sealed cavity as the latch mechanism moves to the latched position.
