Patent ID: 7823756

Claim:
A valve for use with a container and cap combination, the container having an outlet, the outlet including elongated sidewalls that extend from the container that form a passageway through which product passes when the container is being filled or emptied, the outlet having a mouth on the end opposite the point the sidewalls extend from the container, wherein a portion of the sidewalls proximate the mouth is threaded, the cap having mating threads on its interior surface removably securing said cap to the threaded sidewalls for closing the passageway, said valve comprising: a flexible, accordion-type bellows restrictor integrated into the sidewalls, said bellows restrictor being movable so that when an external force is applied to the sidewalls space between the bellows is reduced thereby closing the passageway to prevent product from leaving the container, and when the force is removed space is created between the bellows thereby opening the passageway, allowing product to enter or exit the container; and at least one pair of arms that can lockingly engage the cap, said at least one pair of arms communicating with the movement of the bellows so that the arms simultaneously disengage the cap when the external force is applied to the bellows.
