Definitions

  • the present invention relates to an aerosol valve and to such valve for use in combination with a container for a pressurized fluid which is adapted to be dispensed in the form of a spray mist or as a foam depending upon the container contents.
  • the containers usually have an open top to which the aerosol valve is attached either prior to or after the propellant, usually a low boiling point fluid, is charged into the container.
  • the procedure is referred to as cold filling which requires the operation to be carried out under refrigeration i.e., at a temperature below the boiling point of the propellant.
  • the propellant is charged into the container after mounting the valve thereto, the propellant in fluid form under high pressure is forced into the container usually through and/ or around a hollow valve stem upon unseating the valve and this procedure is referred to as pressure filling. Due to the small dimensional limitations of the valve stem and the passages therein pressure filing has been heretofore relatively slow.
  • valves To increase the pressure filling rate special types of valves have been devised for charging the propellant into the container either through the valve chamber in which the valve is mounted or around said chamber housing through a space or passages between the valve chamber housing and the container closure or mounting cap member. These valves have not proved to be entirely satisfactory because either of their higher cost than conventional valves or of imperfect operation under commercial pressure filling conditions.
  • An object of the present invention is to provide an improved aerosol valve adapted for use in charging and discharging aerosol products from containers which obviates the objections to prior valves.
  • a further object of the invention is to provide an improved valve for aerosol containers in which the pressure fill passages are independent of the discharge passages.
  • a further object of the invention is to simplify the construction of valves for aerosol dispensing which can be completely assembled by the valve manufacturer and used as assembled for either cold filling or pressure filling of aerosol containers with the propellant medium.
  • a still further object of the invention is to provide a valve assembly as set forth in the preceding paragraph which will be simple in construction, efficient in operation and which can be manufactured and sold competitively with conventional cold filling valves.
  • H6. 1 shows an embodiment of the invention in elevation with the cap member and the container upon which it is mounted in diametrical section.
  • FIG. 2 shows a diametrical sectional view of the valve assembly of H6. 1 on a greatly enlarged scale.
  • FIG. 3 is a view similar to FIG. 2 showing the relationship of the valve assembly parts during pressure filling of the container with a fiuid propellant.
  • FIG. 4 shows a top plan View of the tubular housing or spring cup.
  • PEG. 5 shows a transverse section taken along the plane of the line 5-5 of FIG. 4.
  • FIG. 6 is a diametrical section through the sealing washer or valve seal.
  • the invention may be said to consist of an aerosol valve assembly ll? adapted to be mounted in the open end of a container 11 and provide a closure therefor.
  • the valve assembly in consists of a tubular housing or valve and spring cup 12 having a chamber 13, an elastomeric sealing Washer or valve seal 14, a discharge valve member 5, a spring 16, and a container closure or cap member 17.
  • the container ll may be of any desired shape and construction provided it has an open top adapted to be closed by the valve assembly 16.

Between the bore diameters l9 and 2% there is formed a shoulder 22 and the outer portion of the bore 19 is tapered outwardly to its top as shown at 23 whereas the housing is formed with circumferentially spaced radial slots, grooves or flutes 24 providing ribs 24' which communicate with longitudinal slots, grooves or flutes 25 providing ribs 25 formed in the peripheral flange 18.
  • the inner Wall of the housing 12 having the diameter Zll is formed with a plurality of circumferentially spaced longitudinally extending ribs 26 i which are of increasing radial thickness as they extend inwardly from a location below the shoulder 22 to the base of the chamber. Alternate ribs 26 at their inner ends continue across the base 27 of the chamber to a reentrant nipple 23 to provide a seating surface for the spring 16.
  • the tubular housing may be formed of any suitable material, preferably a synthetic resin which may be molded, such as nylon or the like, which is inert to substances intended to be discharged from the container.
  • the sealing washer or valve seal 14 is preferably flat and may be formed of any elastomeric material which is not adversely affected by the substances intended to be discharged from the container and preferably is formed with a central hole or perforation lda the wall or"- which tapers outwardly toward the top face of the washer and has an outer peripheral Wall l ib which is concave in radial section as best shown in HG. 6.
  • the outer diameter of the washer is such as to be normally supported on the tapered portion 23 of the bore portion l? to provide a fluid tight seal therewith and be moved inwardly into the bore portion 1? under fluid pressure applied externally to its outer surface to seat on the shoulder 22, as will be hereinafter more fully explained.
  • the valve member 15 has a solid or closed inner end 29 formed with an inwardly extending axial projection 2% and an outwardly extending hollow cylindrical stem 30 which is open at its top and is slidable in the opening 14a of the washer 14 with a fluid tight fit, said closed end of the valve having an outwardly extending annular flange 3i spaced radially from the lower end of the tubular stern and providing therewith an annular channel 32 and the inner end of the tubular stem 3% is formed with an orifice 359a communicating with said channel.
  • the valve member 15 may be formed of any suitable material, such as nylon or other synthetic resin, which is inert to the substances to be discharged from the container.
  • the container closure or cap member 17 is of cup shape form and has a centrally re-entrant tubular part or pedestal 33 and an outer peripheral bead or flange 34 for attachment or" the valve assembly to the container 11.
  • the tubular part of pedestal 33 surrounds the periphery of the flange 13 and has its upper end formed as an inwardly directed top flange 35 overlying the sealing washer l4 and terminating in axial spaced relation to the tubular stem as shown at 36.
  • the inner end of said tubular part or pedestal 33 is staked inwardly at circumferentially spaced locations to engage the lower corner 18 of the flange 13 as shown at 35:: to support the valve parts and to hold the washer and housing in fluid tight engagement.
  • the staking is preferably of less depth than the groves 25 or ribs 25 to insure maximum passage of fluid propellant when charging the container with the propellant during pressure filling the container.
  • an operating cap or button 37 of generally cylindrical form of smaller diameter than the pedestal 33 the button having a discharge opening 37a connecting with a passage 38 which in turn communicates with the bore in the hollow stem 30.
  • a dip tube 39 is attached to the inwardly extending nipple 21.
  • the tubular housing or spring cup 12 is formed at its upper or outer end with a flange having transverse groves or flutes 2- 4 which communicate with longitudinaily extending grooves or flutes 25 which flutes in conjunction with the contiguous parts of the cap member provide unobstructed passages which open into the container;
