Definitions

  • the cup also comprises a central chamber having a substantially coaxial hole in its bottom.
  • a slidable sealing member is movable inside the central chamber in the cup along the axis thereof and is biased upward by a spring inside said central chamber.
  • This sealing member is annular and is provided with a preferably circular cylindrical seat at its upper end.
  • the device also comprises a spout which is open at its upper end and carries a preferably circular central external rib adapted to engage the seat in the lower part of the slidable sealing member.
  • the spout is provided with at least one radial hole near its lower end and another radial hole at a level just above the shoulder.
  • the device comprises a sealing ring encircling the spout and resting on the upper edges of the outer cup, the sliding sealing member and the circular rib on the spout.
  • valve described in my prior application it is sometimes necessary to use the valve described in my prior application to dispense at least one product which is capable of leaving a residue inside the valve, which eventually stops up the passages and orifices therein.
  • This valve is of the general type described in U.S. application, Ser. No. 839,842, now U.S. Pat. No. 3,593,886, and comprises an outer cylindrical cup, a sliding sealing member which may be moved inside a central chamber in said cylindrical cup, and a cylindrical spout axially mounted in said sliding sealing member, which valve is essentially characterized by the fact that, at the level of the lower radial hole in the spout, the sliding sealing member which grips this spout in a fluidtight manner has at least one notch or orifice in its lateral wall.
  • valve spout is provided with a marlt at its upper end lying on substantially the same generatrix as the center of the hole in the lower part of the spout, and means fixed to the valve which also carries a mark in the same axial plane as the notch in the sliding sealing member.
  • valve When the user sees fit to do so, independently of any dispensing operation, he may internally purge the valve according to the invention by turning the spout of the valve about its axis until the lower hole in the spout is opposite the notch or orifice in the lateral wall of the sliding sealing member.
  • the spout and the stationary components of the valve carry indicia such as those above described, it suffices to bring the marks carried by the spout and the stationary component of the valve into register. At this moment, the
  • propellant gas inside the outer container may escape through the central passageway in the spout by passing first into the central chamber in the cylindrical cup, which chamber is in communication with the inside of the outer container, as indicated in U.S. application, Ser. No. 839,842, now U.S. Pat. No. 3,593,886 issued July 20, 1971.
  • This fluid then travels through the notch in the lateral wall of the sliding sealing member and through the hole in the lower part of the spout, which hole is in aligtment with said notch.
  • the inner passageway in the dispensing spout of the valve is thus effectively cleaned.
  • the present invention also relates to a dispenser for at least one pressurized fluid essentially characterized by the fact that it comprises a dispensing valve of the type described.
  • FIG. 1 is an axial section taken through the valve according to the invention, showing it in cleaning position, in which position the products stored cannot be dispensed;
  • FIG. 2 is an axial section taken through the valve according to the invention showing it in the position in which the products stored are being dispensed and the pressurizing gas is nevertheless introduced into the spout a an additional propellant.
  • reference numeral 1 indicates the outer cup of the valve.
  • the ,cup I is generally cylindrical in shape and has an axial central hole 2.
  • Two diametrically opposed spouts are carried on its bottom and its upper edges are notched at 5 and 6.
  • the notches are in alignment with the spouts 3 and 4 respectively.
  • Passageways 7 and 8 in the wall of the cup connect the spouts to the notches.
  • the cup carries an outer shoulder 9 and the bottom of the cup is pierced by an axial hole la.
  • Sealing member 10 is essentially annular and carries an upper flange 11, the outer diameter of which is equal to the inner diameter of the chamber 2.
  • the lower face of the flange ll rests on a spring 12 inside the central chamber 2, which spring biases the sealing member 10 upward.
  • the sealing member 10 has an annular seat 13 at its upper end, and there is a notch 50 in the lateral wall of the slidable sealing member at its lower end.
  • a spout I4 is positioned in the center of sliding sealing member 10.
  • the spout 14 has a generally cylindrical shape. It carries a circular external rib 15, the outer diameter of which is equal to the inner diameter of the seat 13 at the top of the sliding sealing member 10. immediately above the rib IS the spout 14 is pierced by two diametrically opposed holes 16 and, near its lower end, by two diametrically opposed holes 17. At its upper end, in the axial plane containing the axes of the two holes 17, the spout 14 carries two marks 51 which are diametrically opposite each other.
  • a sealing ring 18 is positioned at the top of the valve. This ring has an external diameter equal to the external diameter of the shoulder 9 and an inner diameter equal to the external diameter of the spout 14. It rests on the upper edges of the outer cup I, the sliding sealing member 10 and the rib 15.
  • the spring 18 When the spring 18 is positioned inside the cup 1, the notches and 6 in the upper edge of this cup are converted into holes.
  • the sealing ring 18 is fastened to the cup 1 by a metallic cap 19 which grips the sealing ring and the shoulder 9 on the cup 1. it is obvious that the cap 19 has a central hole 20 in which the spout 14 is freely movable.
  • the cap 19 carries a mark 52 in the axial plane of the valve which contains the median plane of the notch 50.
  • the cap 19 is adapted to be crimped to the upper part of an outer jacket, which jacket may hold flexible inner containers, which in turn hold the two products to be simultaneously dispensed.
  • the outer jacket also holds the pressurizing fluid which is to place the products in the flexible containers under pressure. This fluid may be a conventional Freon.
  • the upper parts of the flexible containers which hold the products to be dispensed are in the form of tubes 21 and 22. These tubes are attached to the spigots 3 and 4.
  • the introduction of pressurizing gas into the outer jacket may be elfectuated through the passageway in the spout by deforming the lower part of the sliding sealing member 10. In the embodiment according to the present invention this method of introduction may be used. But it is also possible to bring the two marks 51 and 52 into registration and then introduce the pressurin'ng gas into the outer jacket to which the valve is attached.
  • the pressurizing gas passes through the spout, through one of the holes 17 and the notch 50 which is in alignment therewith, then through the central chamber and the hole In in the lower part of the central chamber. it will be seen that the outer jacket may thus be filled without having to deform the sliding sealing member.
  • the user exerts pressure on the spout 14 of the valve or on a suitable member mechanically connected to the upper end of this spout.
  • This movement of the sealing member clears the notches 5 and 6, thus permitting each of the products to be dispensed to escape through the passageways 21 and 7 on the one hand and 22 and 8 on the other hand.
  • the pressure exerted by the Freon in the outer jacket forces these products into the central passageway in the spout 14 through the holes 7, which are open because of previous movement of the spout 14.
  • the spring 12 returns the sliding sealing member upward until the upper surface of the sliding sealing member 10 and the rib 15 on the spout come into contact with the sealing ring 18. During this movement, the notches 5 and 6 through which the fluid is dispensed are blocked, and the holes 16 are also blocked since they are then covered by the sealing ring 18.
  • this spout is turned about its axis so as to bring one of the marks Sl into alignment with the mark 52 carried by the cup 19.
  • the pressurizing gas contained in the outer jacket may escape by passing through the notch 50 in the sliding sealing member, through the hole [7 in alignment therewith, and through the central passageway in the spout 14. This release of pressurizing gas cleans the dispensing passageways of the valve.
  • a dispensing valve for dispensing pressurized fluids from a plurality of flexible containers enclosed in an outer 0 jacket containing a pressurizing fluid comprising:
  • a cup having a peripheral wall and defining a central chamber, said cup having an opening in the lower part thereof for admitting pressurin'ng fluid from said jacket to said central chamber and said peripheral wall having a plurality of passageways therethrough, each for connection to an individual flexible container for holding a product to be dispersed and each terminating in the upper part of said chamber,
  • a manually movable spout projecting through said upper sealing ring into said chamber and defining a central dispensing passage, said spout being provided with first radial openings leading from said dispensing passage to the exterior of said spout and being movable between a first position in which said first radial openings are blocked by said upper sealing ring and a second position within said upper part of said chamber in which said first radial openings are in communication with the passageways in said cup, and
  • said lower sealing means is provided with at least one radial opening into said lower part of said chamber and said spout is provided with a lower radial opening, said spout being rotatable within said lower sealing means between a first radial position in which the lower radial opening therein is in alignment with the radial opening in said lower sealing means and a position in which it is not.
  • Valve as claimed in claim I mounted on a jacket top provided with indicia in alignment with the radial opening in said lower sealing ring, and said spout having a portion projecting upward from said container top and bearing indicia in alignment with the lower radial opening in said spout.
