ABSTRACT:
This invention describes a cap for use with a poppet valve of the type having a movable poppet plunger for controlling the dispensing of liquids from a bottle. The cap is a unitary molded member having a centrally located cylindrical opening at only one end. The inside diameter is adapted to contact a top portion of the movable poppet plunger whereby inserting or removing the cap over the poppet valve opens or closes the poppet plunger respectively. A circular ring attached to the top of the cap at a position located over the closed end of the cylindrical opening allows the user to remove the cap and open the poppet valve with a single movement. Similarly, replacing the cap on the poppet valve automatically closes the poppet valve in a single motion.
