ABSTRACT:
The instant moveable valve assembly mainly comprises a piston body and a moveable valve body associated with the piston body. The moveable valve has at its middle portion a sleeve which is provided with a flattened shoulder. The outer edge of the flattened shoulder is formed with a projection while the lower end of the sleeve is furnished with an outward projection having an inverted triangular shape. In use, the pressure generated by the pressurized liquid perfume in a perfume bottle can be efficiently applied to the flattened shoulder and the outward projection of the sleeve in order to facilitate the downward movement of the sleeve.
