ABSTRACT:
Valves for use with a pressurized receptacle are disclosed comprising a housing including an orifice for dispensing a fluid, a shutter disposed in the housing and movable along the axis of the housing under the action of gravity between a closed position in which the shutter substantially closes the orifice when the valve is in a predetermined orientation and a dispensing position in which the shutter releases the orifice, and at least one surface adapted to prevent movement of the shutter parallel to the axis of the housing over at least a portion of the patch between the closed position and the dispensing position.
