Definitions

  • An aerosol valve assembly is provided for mounting to an aerosol container holding a fluid under pressure.
  • the assembly comprises a hollow cap having a flexible top portion and a downwardly extending continuous wall terminating into a peripheral attaching means, the cap having a nozzle associated therewith.
  • the cap has an aerosol-receiving chamber within it communicating with the nozzle and with a centrally located sleeve depending downwardly therefrom through which a vertically movable stem passes with clearance.
  • the cap has associated with it an annular cup which forms the bottom thereof and which has a fluidcoupling means extending therefrom, the cup being connected and sealed to the bottom ofthe cap.
  • a valve is provided at the opening of the fluid-coupling means of said cup in sealing contact with the end of said sleeve such that when the flexible portion of the cap is depressed to move the stem downward against the valve, the valve is caused to move out of sealing contact with the sleeve, whereby aerosol fluid under pressure is caused to enter the space between the sleeve and the stem and into the aerosol-receiving chamber for expulsion through said nozzle.
  • ROBERT L WEBERM BY a g A TTORNEYS' Patented Nov. 24, 1970 Sheet @J VVWVM FIGII INVENTOR.
  • ROBERT L WEBER IF A 'r'ronusys FIG. l3
  • This invention relates to a low force aerosol valve and, in particular, to a low force aerosol valve capable of providing predetermined metered quantities of aerosol fluid.
  • Aerosol valve assemblies for dispensing pressurized fluids, particularly metered quantities of fluids are well known in the art.
  • nonmetering valve assemblies comprise a housing with a finger-actuated cap and orifice coupled to a valve stem associated therewith, said housing having an aerosolreceiving chamber therein including a valve member capable of being actuated by the stem when finger pressure is applied to a cap.
  • two serially related valve means on either side of the chamber are employed. Finger pressure on the cap and hence on the valve stem causes the upper valve to open to dispense the product while closing the lower valve. Release of finger pressure closes the upper valve and opens the lower valve to refill the chamber.
  • the chamber is therefore normally under the same pressure as th the-product container.
  • the pressure in the product container is generally high, for example, as high as 40 lbs/in and higher, leakage is apt to occur through the upper valve of the chamber due to the continually acting high pressure, whereby the pressure may eventually spend itself.
  • biasing means such as a spring
  • FIG. 1 is an exploded view in elevation of one embodiment of a low force nonmetering valve provided by the invention showing the parts making up the valve assembly;
  • FIG. 1A is a cross section of the valve stem taken along line A-A of FIG. 1;
  • FIG. 2 shows the parts of FIG. 1 in the assembled state, including a portion of an aerosol container
  • FIG. 3 is an enlarged cross section of the valve assembly of FIGS. 1 and 2 showing the actuation of the valve on the downstroke;
  • FIG. 4 is an exploded view similar to FIG. 1 of a metering valve assembly provided by the invention.
  • FIG. 4A is a cross section ofthe valve stem taken along line 8-3 of FIG. 4;
  • FIG. 5 shows the parts of FIG. 4 in the assembled state, including a portion of an aerosol container
  • FIG. 6 is an enlarged cross section of the valve assembly of FIGS. 4 and 5 showing actuation of the valve on the downstroke;
  • FIGS. 7 and 8 are illustrative of additional embodiments of a nonmetering valve assembly showing various forms of valve stems
  • FIGS. 9 and 10 are other embodiments of metering valve assemblies utilizing forms of valve stems similar to FIGS. 7 and 8;
  • FIG. 11 is an embodiment similar to FIG. 8 illustrating theuse of an annular rigidizing means for the cap
  • FIG. 12 is an embodiment ofa metering valve portion showing in enlarged cross section one means of assuring low force actuation.
  • valve means on either side of a chamber, such that on depressing a retractable, valve-actuating discharge member, the lower high pressure valve, which is spring biased in the closed position, is opened to allow the product to enter the chamber while the upper valve is closed.
  • the retractable valve-actuating discharge element releases itself from the lower valve which is immediately closed by its biasing spring, following which the retractable element on'returning to its home position causes the upper valve to open and release the metered quantity of l the product.
  • the metering chamber is at atmospheric pressure except for the brief moment during actuation.
  • the lower valve is spring biased
  • a disadvantage of most conventional valve assemblies is that a plurality of elements or parts are usually employed. As the parts are generally very small, they must be precise in size in order to insure cooperation of the parts in the finally assembled structure. This adds to the cost of the item. It would be desirable in providing a low force aerosol valve assembly to employ a minimum number of parts to assure foolproof performance and to provide a means of easily filling the aerosol vessel or container.
  • Another object is to provide a low force aerosol metering valve in which leaking isgreatly minimized, which is simple in construction and which is economical.
  • a still further object of the invention is to provide an improved metering valve assembly having a high pressure valve that does not require the use of biasing means to maintain it in sealing engagement on the high pressure side of the metering chamber.
  • FIG. 13 is an embodiment similar to FIG. 3 except that the top of the cap is tapered to assure low force actuation.
  • an aerosol valve assembly comprising a hollow cap having a flexible top portion and a downwardly extending continuous wall terminating into a peripheral attaching means or collar, a nozzle associated with the cap and an aerosol-receiving chamber associated with the inner surface of the cap, the chamber communicating with the nozzle.

  • Forming the bottom of the cap is an annular thinwalled cup having fluid coupling means extending therefrom, the cup being mechanically joined and sealed to the bottom of the cap.
  • a valve is provided supported at the opening of the fluid-coupling means of said cup in sealing con tact with the end of the sleeve such that when the flexible portion of the cap is depressed to move the stem downward against the valve, the valve is caused to move out of sealing contact with the sleeve, whereby aerosol fluid under pressure is caused to enter the space between the sleeve and the stem and into said aerosol-receiving chamber for expulsion through the nozzle.
  • an aerosol valve assembly comprising a hollow cap having a flexible top portion and a downwardly extending continuous wall terminating into aperipheral attaching means, a nozzle associated with the cap, and a thin-walled annular chamber nesting within the cap and forming a housing therewith.

  • FIG. 11 which is substantially the same as FIG. 8, the same numerals being employed to designate the same parts, shows an annular reinforcement 40 of metal encompassing a portion of top 14b of the cap. The purpose of the reinforcement is to stiffen that portion of the cap against bending during applied finger pressure so that only the thin portion 14:! of the cap flexes downwardly. This limits the area of applied pressure and hence the amount of actuation force.

  • Annular chamber 42 of sheet metal is fitted snugly within the cap and is configurated at 43 to abut and support thickened portion l4e while leaving an annular space 44 beneath thin portion 41 of the cap.
