Definitions

  • the valve comprises a hollow body, in
  • the valve comprises a second hollow extension communicating with a chamber connected to a further chamber by a duct which, under inoperative condi- 4 ml m3 0 0 5 .3 B9 u 0 H m m B "/"M mn M23 "m mmw "2 m 2 NO uflM 2 L02 d Ld h UN 55 ii 304 tions, is closed by a seal pressed by a flange projecting the valve stem on which a spring is operative.
  • two longitudinal conduits are provided, at the lower end of which in the stem two distinct small holes are provided and located above said seal.
  • This invention relates to a valve for dispensing two distinct liquids from an aerosol container, and more particularly a valve applicable to an aerosol container and capable of dispensing two different liquids which are kept separated from each other within the container.
  • Aerosol containers are known, in which two distinct liquids are introduced, one liquid being introduced directly into the container, and the other liquid being introduced into a deformable vessel accommodated in said container.
  • Dispensing valves are known as applicable to these containers and suitable to dispense simultaneously the two liquids therein, such valves suffering however from a number of disadvantages.
  • a disadvantage of the prior art valves is that the two liquids are intermixed in a chamber within said valves, which makes it impossible to use such valves in many instances, such as when on mixing the two liquids give rise to chemical reactions, such as of a polimerizing character.
  • the passage into the deformable vessel of some of the gas being introduced into the container is also promoted in that the gas pressure within the valve body is at least initially higher than in the container and deformable vessel during pressure filling.
  • the main object of the present invention is to provide a valve for dispensing two distinct liquids from an aerosol container and by which the two liquids are separately dispensed without mixing within the valve, so as to avoid in any manner the possibility for a flowback of some of the two liquids mixed in the rigid container and deformable vessel.
  • Another object of the invention is to provide a valve of the above character which, after being tightsealingly applied to the inlet of the above mentioned design of container, will allow to directly introduce into the container a high pressure propelling gas following the introduction into the container of the two liquids to be dispensed, preventing any possibility for this gas from entering the deformable vessel arranged in the container.
  • a still further object is to provide a valve for sealingly separate the two liquids in the container and preventing any leakage to the outside, so that the container can be pressurized and maintained at this condition.
  • a valve comprising a main body having an inner hollow open at one end of the body, from the other end of which a first hollow extension projects and on which the inlet of a deformable vessel containable within said container can be fitted, a shaped disc overlying the main body at the opening of the hollow thereof, a wall projecting outwardly of the main body and by which said disc defines a first chamber communicating with the hollow ofthe main body through at least one duct, a
  • a plunger having an enlarged head located within the hollow of the main body, a stem extending therefrom and being accommodated and movable within the bore of the first extension, this bore having a cross-section area larger than that of the plunger stem, a valve stem having an end thereof within the hollow of the main body and the other end thereof outward extending through a hole of said seal and a hole of said disc, and a second chamber provided between the outer surface of the valve stem, the seal and disc, an annular flange extending from the stem portion within the hollow of the main body, this flange being acted upon by a spring accommodated within the hollow of said main body and which, under valve inoperative conditions, urges the stem
  • FIG. 1 is a cross-section of a valve at inoperative conditions, as fitted on an aerosol container;
  • FIG. 2 is a sectional view showing the valve when introducing a propelling gas directly into the container, on which said valve is fitted;
  • FIG. 3 is a sectional view showing the valve at dispensing attitude.
  • the valve comprises a main body 1 having an inner hollow open at one end of said body and from the other end of which there projects a first hollow extension 2, on the lower end 3 of which the inlet 4 is fitted for a deformable vessel 5 containing a liquid and accommodated, in turn, within a container 6.
  • a shaped disc 7 overlies and with a wall outwardly projecting from the body 1 forms a first chamber 8 communicating with the hollow of body 1 through a number of ducts 9, only one of which being shown in the drawing.
  • a resilient seal 10 is located: said disc 7, seal 10 and body 1 are sealingly made integral to one another by a bottom 11 which is seamed or riveted below the free projecting edge of body I, as clearly shown in the drawing, and which can be fitted, in turn, on the inlet of an aerosol container 6, as shown in the drawing.
  • tubular extension 12 projects, one end of which opens on the first chamber 8, and the other end of which is free and carries a drawing tube 13 extending to the bottom of container 6.
  • the valve also comprises a plunger having an enlarged head 14 located within the hollow of body 1, a stem 15 extending therefrom and being accommodated and movable within the hollow of the first extension 2, the hollow of this extension 2 being of a cross-section area larger than that of said stem 15.
  • Disc 7 has a central hole, at which a cylindrical wall 16 extends and has its free edge inward bent, as shown in the drawing.
  • Seal 10 also has a hole and through this hole and that of disc 7 the valve stem extends which, in the embodiment shown, is made of two pieces fitted to each other, of which one piece comprises a tubular element 17 having an enlarged free end and the other piece having at the bottom an annular flange l8 and at its top portion 50 having a longitudinal seat, in which the tubular element 17 is inserted and the outer surface of which defines with the adjacent surface of the other piece 50 a longitudinal conduit 19 parallel to the conduit 20 defined within the element 17, this conduit 20 opening at the free end of the valve stem and conduit 19 opening on the side surface of said stem.
  • a small hole 21 is formed adjacent the lower end of the conduit 19 and a small hole 22 is also formed adjacent the lower end of conduit 20.
  • These small holes are both positioned above said flange 18 and are spaced apart from each other along the stem so that, under the conditions at which the valve stem is held upward urged by a spring 23, neither of them will open into the hollow of body 1; under these conditions, which are the inoperative conditions shown in FIG. 1, said spring 23 urges the stem flange 18 against the seal 10, pressing it against the disc 7, closing the duct 9 and separating the first chamber 8.
  • a second chamber 24 is formed which, under the inoperative conditions, is also separated due to seal 10 from the first chamber 8 and hollow of body 1.
  • annular groove On the outer surface of the valve stem an annular groove is provided, at which said small hole 22 is located and the seal 10 is positioned for a sealing effect on the stern surface, as shown in FIG. 1.
  • said disc 7 is preferably made of a softer material than that comprising said body 1. All of the elements comprising the valve are advantageously made of plastic material, except for the spring which is made of metal and the seal which is of rubber.
  • a dispensing cap On the end of the valve stem projecting from the aerosol container, a dispensing cap can be fitted, such as that shown in FIG. 1.
  • This cap comprises a body 25, in which a glass or socket type of element 26 defines a chamber 27 communicating with the conduit 20 through a hole 28 and communicating with the conduit 19 through a hole 29, this chamber 27 communicating in turn with the outside through a hole 30 on the bot tom of the glass or socket element.
  • the vessel 5 made of deformable plastic material, contains one liquid and a different liquid is in container 6, in which also a pressure gas is provided.
  • a pressure gas is provided.
  • the liquid in the deformable vessel 5 rises up a small tube 31 carried on the lower end 3 of the first extension, causes the plunger to raise as shown in said FIG. 3 and then, by flowing into the space between the stem and the adjacent surface of the first extension, enters the hollow of body 1, passes to the small hole 22 now not closed by seal 10, rises up along the stem conduit 20 and reaches the dispensing cap chamber 27 by passing through the hole 28.
  • the liquid in the container outside the vessel 5 rises up along the tube 13 and the hollow of extension 12, fills up the first chamber 8 and passes to the second chamber 24 through the duct 9, which is now not closed by the seal 10, the latter being downward deflected by the stem.
  • This liquid, from chamber 24 via the small hole 21, conduit 19 and hole 29 also reaches the cap chamber 27, where it intermixes with the liquid from the vessel 5, the so mixed up liquid exiting then from the hole 30 of element 26.
  • valve stem is lowered relative to the main body 1 attached to the bottom as shown in FIG. 1, and a high pressure gas stream is supplied; this gas enters the container through the conduit 20 and small hole 22, but is prevented from entering the vessel 5 through the hollow of extension 2 as the upper opening of said hollow is closed by the plunger head 14, the latter being firmly on the underside of body 1 by the gas pressure in the hollow of said body 1, this pressure being higher than that in said vessel 5.
  • the gas via conduit 19, small hole 21, chamber 24, duct 9, chamber 8 and hollows of extension 12 and small tube 13 enters the container 6 and pressurizes it.
  • the gas could also flow between the adjacent surfaces of the bent edge of wall 16 of disc 7 and the outer surface of the stem to reach the chamber 24 and therefrom through duct 9 again into the container.
  • some of the gas in chamber 24 could enter the hollow of body 1 downward deflecting said seal 10, but the gas therefrom cannot enter the vessel 5 according to the above statement.
  • a dispensing valve for two distinct liquids from an aerosol container comprising a main body having an inner hollow open at one end of the body, from the other end of which a first hollow extension projects and on which the inlet of a deformable vessel containable within said container can be fitted, a shaped disc overlying the main body at the opening of the hollow thereof, a wall projecting outwardly of the main body and by which said disc defines a first chamber communicating with the hollow of the main body through at least one duct, a resilient seal between the disc and the main body, a bottom capable of being secured to the inlet of an aerosol container and rigidly bonding the disc to the seal and main body, a second tubular extension projecting laterally of the main body and one end of which opens on said first chamber and on the other end of which a drawing tube insertable in said container is fitted, a plunger having an enlarged head located within the hollow of the main body, a stem extending therefrom and being accommodated and movable within the bore of the first extension, this bore
  • valve as claimed in claim 1, wherein on the outer surface of the valve stem an annular groove is provided, at which that small hole closer to the flange projecting from the stem is located and at which said seal is positioned under the inoperative conditions of the valve.
  • valve stem portion projecting externally of the main body hollow has a longitudinal seat in which a tubular element is inserted, the outer surface of this tubular element defining with the adjacent surface of said stem one of said longitudinal conduits, the other of which being defined by the hollow of the tubular element.
