ABSTRACT:
A fluid control valve which has a deformable valve member with a fluid passageway therethrough. The fluid passageway is closed by a pressure-exerting member. Initial actuation of the valve by pressure on an actuator assembly compresses a spring which moves the pressure-exerting member away from the deformable valve member, thus allowing the fluid passageway to open. The fluid control valve also having a base portion containing a tortuous path air channel. When the base portion is fitted against a neck plug of a reservoir, a vent opening in the neck plug opens into the air channel of the base, allowing air to enter the reservoir while preventing liquid from leaking out of the reservoir should the reservoir be tipped over.
