Definitions
- ABSTRACT Cl 251/333 A sealing system for pressurized container valves parllit. Cl. ticula -ly designed for the dispensing of solid products
- Aerosol dispensers commonly contain a supply of the product to be dispensed together with a quantity of propellant in liquid form, all held within a pressurized container.
- the valves in such devices are actuated by a movement of the valve body with respect to the pressurized container which movement uncovers an orifice completing a path from the container to a discharge nozzle.
- the product to be dispensed and the propellant are forced along the path by the pressure of the propellant within the container.
- valve sealing is accomplished primarily by radial force exerted on the valve body by its encircling gasket.
- the valve body typically includes a narrow cylindrical section including the valve orifice and encircled by the gasket.
- a conical tapered section above the cylindrical section is topped by an upstanding valve stem.
- the orifice in the narrow cylindrical section communicates with a hollow interior passage in the valve body leading to the discharge orifice.
- the narrow cylindrical section and at least a portion of the conical tapered section are encircled by the aperture of an annular resilient gasket when the valve is closed, but when the valve body is depressed, the conical tapered section causes the inner aperture or sealing surface of the gasket to peel away from the valve body, thereby opening the dispensing path through the orifice.
- a protruding annular ridge is provided about the narrow cylindrical section of the previously described valve body, and the valve orifice is located in a position above this ridge, in the upper region of the cylindrical section or in the conical tapered section of the valve body.
- the protruding ridge presses into the resilient gasket, providing a labyrinthine sealing contour less likely to leak than previous constructions.
- depression of the valve body for valve actuation results in some relative motion of the valve body with respect to the sealing surface of the gasket which moves the ridge with respect to the sealing gasket. This tends to dislodge accumulations of undispensed solid product.
- flow is terminated before the gasket is restored to its radially compressed engagement with the valve body thereby providing an opportunity for disentrained particulate matter in the sealing region to fall away from that region.
- FIG. 1 is an elevational view in partial section showing the valve of the present invention in the closed position
- FIG. 2 is an elevational view in partial section showing the same valve during actuation, with the valve orifice shown rotated laterally from its position in FIG. 1.
- Valve assembly 10 includes dip tube 12, dip tube receiving nipple 13, valve housing 14, coil spring 15, and valve body 16.
- a resilient annular gasket 17 encircles a section of valve body 16.
- Valve body 16 includes an upstanding hollow valve stem 19, below that a conical tapered section 20 containing an orifice 21, then a narrowed cylindrical section 22 having an encircling protruding annular ridge 23, and finally a lower portion 24 adapted to receive a coil spring 15. Shoulder 25 is formed by the intersection of the narrow portion 22 and the lower portion 24 of valve body 16.
- valve is actuated by applying sufficient down-. ward force on valve stem 19 to overcome the upward bia:v of spring 15.
- taper :d section 20 deflects downward the inner edge of gas Kt 17, causing it to peel away from orifice 21 and eventually expose the orifice 21 to the pressurized product within the container.
- shoulder 25 will leave contact with the underside of gasket 17 and the inner edge of gasket 17 will be partially peeled away from valve body 16.
- orifice 21 is located at a higher position on the valve body than in most valves of this type,
- valve body 16 simply moves downward, while points on the inner sealing surface of gasket 17 move both downward and radially away from the valve body and also undergo some compression.
- This deflection of the gasket results in motion of the inner sealing surface of the gasket with respect to the valve body 16 and its integral ridge 23.
- a given point on the gasket sealing surface moves downward a smaller distance during the opening operation than the adjacent point on valve body 16. Therefore, as ridge 23 moves downward, there will be relative vertical movement between the ridge and the surrounding inner sealing surface of gasket 17.
- This rel ative motion tends to dislodge product residues present on the valve body or the gasket sealing surfaces. If the product residue is in the form of agglomerations or clots, the ridge 23 will tend to pulverize the clots upon closure motion and tend to dislodge the clots from the sealing surface.
- a dispensing valve for a pressurized aerosol container comprising:
- valve body movable axially with respect to the housing between closed and open positions, the valve body having a discharge passage communicating with the exterior of the container, and a valve orifice extending radially into communication with said discharge passage,
- annular resilient sealing gasket having a central aperture defined by a sealing surface encompassing and sealing said valve orifice when the valve body is in the closed position
- annular ridge means encircling said valve body located interiorly of the container from the valve orifice on a portion of the valve body encompassed and sealed by the resilient sealing means when the valve body is in the closed position with said ridge means engaging the sealing surface of said annular gasket.
- valve body includes an upstanding hollow stem portion including said discharge passage, a cylindrical portion of smaller diameter than the stem portion, and an interposed conical portion tapering from the stem portion to the cylindrical portion, the radial valve orifice being located in said conical portion and the ridge means being located on said cylindrical portion.
- ridge means comprises at least one circumferential projection on the valve body in a plane substantially prependicular to the axis of the valve body.
