Valve for a pressurized receptacle

A valve for use with a pressurized receptacle containing a fluid to be dispensed therefrom, said valve comprising a housing having an axis, and including an orifice for dispensing said fluid, a shutter member disposed in said housing, said shutter member movable along said axis under the action of gravity between a closed position in which said shutter member substantially closes said orifice when said valve is in a predetermined orientation and a dispensing position in which said shutter member releases said orifice, and at least one surface adapted to inhibit the movement of said shutter member over at least a portion of the path between said closed position and said dispensing position;

• wherein said housing is not defined by a dip tube.

A valve for use with a pressurized receptacle containing a fluid to be at least partially dispensed therefrom, said valve comprising a housing and a dip tube said dip tube having a longitudinal axis, and said valve including an orifice for dispensing said fluid, a shutter member disposed in said housing, said shutter member movable under the action of gravity between a closed position in which said shutter member substantially closes said orifice when said valve is in a predetermined orientation and a dispensing position in which said shutter member releases said orifice, and at least one surface adapted to prevent movement of said shutter member parallel to said axis of said dip tube over at least a portion of the path between said closed position and said dispensing position.

A valve for use with a pressurized receptacle containing a fluid to be dispensed therefrom, said valve comprising a housing having an axis, and including an orifice for dispensing said fluid, a shutter member disposed in said housing, said shutter member movable along said axis under the action of gravity between a closed position in which said shutter member substantially closes said orifice when said valve is in a predetermined orientation and a dispensing position in which said shutter member releases said orifice, and at least one surface adapted to prevent movement of said shutter member parallel to said axis over at least a portion of the path between said closed position and said dispensing position, wherein said housing includes an inner wall, and said at least one surface comprises a threaded rod including at least one thread which cooperates with said inner wall of said housing to define a substantially helical passage constraining the movement of said shutter member between said closed position and said dispensing position.

A valve for use with a pressurized receptacle containing a fluid to be dispensed therefrom, said valve comprising a housing having an axis, and including an orifice for dispensing said fluid, a shutter member disposed in said housing, said shutter member movable along said axis under the action of gravity between a closed position in which said shutter member substantially closes said orifice when said valve is in a predetermined orientation and a dispensing position in which said shutter member releases said orifice, and at least one surface adapted to prevent movement of said shutter member parallel to said axis over at least a portion of the path between said closed position and said dispensing position, said valve including an absorber disposed downstream of said shutter member in the direction of flow of said fluid, said absorber adapted to absorb at least one propellant gas contained within said receptacle, whereby said absorber can release at least a portion of said at least one propellant gas upon a decrease in pressure in the area adjacent to said absorber.

A valve for use with a pressurized receptacle containing a fluid to be dispensed therefrom, said valve comprising a housing having an axis, and including an orifice for dispensing said fluid, a shutter member disposed in said housing, said shutter member movable along said axis under the action of gravity between a closed position in which said shutter member substantially closes said orifice when said valve is in a predetermined orientation and a dispensing position in which said shutter member releases said orifice, and at least one surface adapted to prevent movement of said shutter member parallel to said axis over at least a portion of the path between said closed position and said dispensing position, wherein said predetermined orientation comprises a head-up position for said valve, and wherein the position of normal use of said valve comprises a head-down position for said valve.
