Definitions

  • a resilient diaphragm is provided for a pressurized metering aerosol valve which comprises a thin sleeve portion surrounding the valve stem of said aerosol valve to cover a valve stem opening therein and control flow of aerosol formulation from the metering chamber through the valve stem opening.
  • the sleeve-like configuration of the diaphragm permits pressure within the metering chamber to compress the diaphragm about the valve stem at the opening thereby enhancing sealing and preventing leakage.
  • Aerosol containers are known to be a very convenient means for dispensing fluids or solids suspended in a fluid stream.
  • valves including those of the metering type tend to clog and inadvertantly limit or even cut off the fluidized stream of the dispensed material when such valves are in an open position. This clogging is invariably caused by caking and the tendency of the finely divided solids to agglomerate within the valve body and subsequently obstruct and hinder proper valve action.
  • FIGURE 1 is a sectional elevational view of the metering aerosol valve of the present invention
  • FIGURE 2 is a sectional view taken along the line 22 of FIGURE 1 and showing the lands of the valve in greater detail.
  • valve operations can be further enhanced by decreasing the coefiicient of friction of the moving parts within the valve assembly.
  • An additional benefit can be gained if the valve stem, selected portions thereof, or the stationary bearing surfaces of the valve assembly are coated with a permanent resilient coating of a halohydrocarbon polymer.
  • Typical illustrative halohydrocarbon polymers are homopolymers of tetrafluoroethylene, copolymers of tetrafluoroethylene and hexafiuoropropylene, and the like.
  • the coelficient of friction between the moving parts of the instant valve can be conveniently reduced by applying thereto a lubricant, which is relatively non-volatile under the normal service conditions of the aerosol valve and which is compatible with the materials of construction employed and with the components of the aerosol system.
  • the lubricant can be applied also over the coated portions of the valve stem.
  • Typical of such lubricants are hydrocarbon oils and greases, silicon oils and greases, and the like.
  • contemplated are the suspensions in the aforementioned oils and greases of solid lubricants such as graphite, molybdenum disulfide, boron nitride, powdered tetrafluoroethylene polymers, and the like.
  • Illustrative silicon oils and greases are organic-siloxane fluid polymers with or without a thickening agent such as reactive silica, silica admixed with reactive boric oxide, soaps, and the like.
  • FIGURES 1 and 2 of the drawing there is shown a valve body or housing 10, and a resilient flanged diaphragm 12 which seals off the upper end of the housing 10 and together with the housing 10 defines a metering chamber 14.
  • Suitable supporting means such as rigid washer 16 overlies the diaphragm 12 and serves to support suitable biasing means, such as compression spring 18, the latter of which is used to maintain the valve assembly in a closed position.
  • the valve stem 20 may be of plastic and is suitably tubular in form and closed at its lower hemisphericallyshaped end 21 (hereinafter described in greater detail).
  • the stem 20 is mounted in the housing 10 and is provided with a longitudinal conduit 22 and an upper lateral valve stem opening 24. If desired, the lower portion of the valve stem 20 below the opening 24 may be solid.
  • a plurality of lands 15 guide and center the valve stem 20 within the valve housing 10. Three lands are suitable in the practice of the invention although four lands are illustrated and described herein.
  • the upper lateral opening 24 is located adjacent to and covered by a depending sleeve portion 25 of the diaphragm 12.
  • the central portion of the valve stem 20 extends through and is slidable in the central bore 26 of the diaphragm 12 and the valve stem is sufficiently long so as to project beyond the top of an aerosol container (not shown) so as to accept an actuator button 28.
  • valve stem 20 Near the upper portion 30 of the valve stem 20 is a suitable protuberance or annular ridge 32 which functions 3 as a shoulder for the spring 18 and as a limit stop for the valve stem 20. If desired, the outside surface of the valve stem 20 may be coated with a halohydrocarbon polymer coating which provides a resilient mating surface with the diaphragm 12.
  • the lower hemisphen'cally-shaped valve means 21 of the valve stem 20 is in proximity to a lower tapered valve stem seat 34 provided in the bottom portion of the valve housing 10.
  • the valve means 21 serves to seal off the tapered opening 36 in valve housing 10 when the actuator button 28 is depressed and the metering valve of the invention is in the open position and expelling the metered charge residing in the metering chamber 14.
  • the seat 34 is noted to have extending tip portion 45 which is urged into sealing engagement with said lower valve means 21 'by the internal gas pressure of said aerosol container. This same gas pressure is noted to aid in sealing said upper valve stem opening 24 with the depending sleeve portion 25 of said diaphragm 12 (see arrows in FIG- URE l).
  • the compression spring 18 is situated externally about the valve stem 20 between the rigid washer 16 and the annular ridge 32 so as to urge the bottom portion 21 of the valve stem 20 away from being in sealing engagement with the conical opening 36 of the valve stem seat 34.
  • the valve assembly of the invention is held in place within an aerosol container by means of a conventional top cover or closure 37.
  • the flange portion 39 and the crimp 41 of the closure 37 provide the means by which the valve assembly is held together and fixedly disposed and suspended within an aerosol container (not shown).
  • the actuator button 28 has a longitudinal passage 40 provided with a discharge orifice 42 the effective diameter of which is greater than that of the stem opening 24 to prevent clogging.
  • the longitudinal pasage 40 communicates with the longitudinal conduit 22 of the valve stem 20 by means of the axial opening 43 at the upper end of the valve stem 20.
  • the valve stem 20 When the actuator button 28 is depressed the valve stem 20 is moved longitudinally to compress against the spring 18 and from a normal sealing or closed position to an open or discharge position.
  • the open or discharge position is reached when the longitudinal conduit 22 communicates with the chamber 14 of the valve housing 10 via the upper valve stem opening 24.
  • the spring 18 Upon release of pressure on the actuator button 28 the spring 18 returns and closes off the upper valve stem opening 24 of the valve stem 20 and opens the lower valve means 21 thus allowing the metering chamber 14 to be filled for the next metered charge.
  • the location of the upper valve stem opening 24 is critical in that is must be such that when the valve stem 20 is moved longitudinally to adischarge position, the upper opening 24 is moved away from its sealingrelationship with'the diaphragm 12 and into communication with the metering chamber 14. At the same time, the lower bottom valve 21 of the valve stem 20 seals off the metering chamber 14 whereby enabling only a predetermined metered quantity of aerosol formulation within the cavity 14 to be expelled from the aerosol container.
  • the tapered opening 36 is noted to be completely sealed before the opening 24 enters the chamber 14.
  • the chamber 14 is filled by the pressurized aerosol formulation with the material to be dispensed when the valve stem 20 is not depressed and the lower valve 21 is in an open position while the upper valve stem opening 24 is in the normally closed or sealing position.
  • the valve stem 20 is subsequently moved to the discharge position, the material contained in the chamber 14 is dispensed through the discharge orifice 42 by means of opening 24, longitudinal conduit 22 and opening 43.
  • the dosage to be dispensed is controlled by the capacity or volume of the chamber 14.
  • the compression spring 18 is externally mounted and does not come into contact with the material to be dispensed so that consequently it cannot be clogged and will essentially be jam-proof.
  • a metering aerosol valve for a pressurized aerosol container including a housing defining a metering chamber containing a pressurized predetermined quantity of aerosol formulation to be dispensed, lower valve means defined by said housing through which aerosol formulation may flow from said container to said metering chamber, a valve stem extending into said housing and defining internally thereof a passageway for dispensing aerosol formulation from said metering chamber, valve stem opening means defined by said valve stem between said passageway and said metering chamber, spring means mounted exterio rly of said valve stem biasing said stem to a closed-valve position and defiectable to permit displacement of said stem to an open-valve position, closure means surrounding said valve stem blocking flow through said valve stem opening means when said stem is in said closed-valve position and permitting exposure of said valve stem opening means to the aerosol formulation in said metering chamber when said stern is in said openvalve position, and means on said valve stem blocking flow through said lower valve means when said stem is in said open-valve position, the improvement
  • said lower valve means comprise a conically shaped opening defined by a conically shaped lip portion extending from said housing, with the end of said valve stem moving into said opening when in the open-valve position, said end of said stern being shaped to block aerosol formulation flow through said valve means, said valve stem end being completely disengaged and out of contact with said conically shaped lip portion when in the closed-valve position thereby penmitting com-pletely free flow of aerosol formulation therethrough.
  • a metering aerosol valve according 'to claim 2 wherein said conically shaped lip portion is configured to be compressed against said valve stem when in the open-valve positon by pressure within said aerosol container thereby enhancing the sealing engagement therebetween.
