Definitions

  • the subject of the present invention is a liquid spray head intended to be connected to a source of compressed gas and to be fixed to an enclosure containing the liquid to be sprayed, comprising a distributor body in which a sliding and integral distribution member is mounted a control button actuated by pressure and provided with a spray nozzle connected to the outlet pipe of the member, said body having an outlet orifice intended to send the propellant gas into the enclosure and an inlet orifice intended to put the enclosure in communication with said outlet duct.
  • the dispensing body is constituted by a cylinder provided with lateral openings in which slides a hollow cylindrical rod also provided with lateral openings cooperating with the holes in the body to form a slide valve.
  • the lower end of the rod acts on the valve of a compressed gas tank screwed to the lower end of the cylinder.
  • the compressed gas tank is placed directly in communication with the liquid to be sprayed. It is therefore difficult to control the pressure in the liquid and impossible to maintain this pressure at a value slightly above atmospheric pressure.
  • the pressure in the enclosure must not exceed a critical value, relatively low, for example 1.1 bar.
  • the present invention aims to provide a spray head for maintaining a controlled low pressure in the enclosure containing the liquid to be sprayed.
  • the spray head according to the invention allows for example to use a compressed gas tank at 10 bars or more and to spray the liquid with a controlled and regulated pressure from 0 to 3 bars or moreover, this low pressure can be adjusted and maintained at a precise value by means of the pressure regulator.
  • the mechanical connection of the valves ensures the correct operation, without loss, of the head and makes it possible to accommodate all of the elements of this head in a cylindrical body of small volume capable of being mounted on an enclosure or bottle of current size.
  • the reservoir can be fixed under the head and introduced therewith into the enclosure when the head is fixed to the opening of the enclosure or fixed around the head outside the enclosure.
  • the body may also have means for plugging into an enclosure also housing a reservoir of compressed gas.
  • the enclosure can be made of both metal and glass.
  • the spray head according to the invention can be used for spraying any liquid.
  • the head comprises a cylindrical body 1 in which are mounted a set of valves 2, a pressure regulator pressure regulator 3 and a safety device 4.
  • the valve assembly is shown in FIG. 12. It consists of two identical valves, superimposed and controlled by a single press button 5. These two valves are of the type used in aerosol cans.
  • the upper valve comprises a valve body 6 provided with two O-ring seals 7 and 8 allowing it to slide in a bore 9 while guaranteeing a sufficient seal in the part of the bore situated below this body 6.
  • a joint press 10 holding a sealing package 11 made of synthetic material crossed by a valve stem 12 minie of a central duct 13 connected in its upper part to a spray nozzle 14 provided in the button 5 and with the inside of the valve body by a lateral hole 15 closed at rest by the package 11.
  • the rod 12 has in its lower part an enlargement 16 by which it abuts, at rest, against the package 11 under the effect of a spring 17 working in compression between the rod 12 and the bottom of the joint press 10.
  • the chamber 18 formed inside the hollow joint press 10 communicates with the inside of the valve body 6 through a hole 19
  • the interior of the body 6 communicates through a hole 20 with a e annular chamber 21 surrounding the body 6 between the 0-ring seals 7 and 8.
  • This annular chamber 21 communicates itself with a conduit 22 opening to the lower part of the body 1 through an inlet orifice 23.
  • the lower valve is identical to the upper valve and comprises, like it, a body 24 provided with two 0-ring seals 25 and 26, a hollow rod 27, a package 28, a press seal 29 and a spring 30. There are also three ports 31, 32 and 33 and an annular chamber 34 which communicates with a conduit 35 connected to a first inlet port 36. The inlet port 23 will be called subsequently the second inlet orifice.
  • a plate 37 provided with a central hole 38 communicating with the conduit 39 of the valve stem 27.
  • the plate 37 also has a radial milling 40 on its face upper forming a conduit communicating the hole 39 with the interior of the bore 9 which is itself connected to a conduit 41.
  • the various elements described can be made either of metal or of synthetic material.
  • the rod 12 is lowered, which, by means of its spring 17 drives the valve body 6 by pushing the valve rod 27 from the lower valve by compressing its spring 30.
  • the spring 30 that is to say work the lower valve, it is therefore necessary to overcome, by means of the spring 17, the frictional force of the body 6 in the bore 9 and the frictional force of the valve stem 27 in its package 28.
  • the springs 17 and 30 are identical, the upper valve opens with a slight advance on the lower valve.
  • the button 5 is released, the same friction causes the upper valve to close with a slight advance on the lower valve.
  • a slight offset has a favorable effect since it prevents untimely escape of the compressed gas.
  • the conduits are formed by drilling along perpendicular axes and plugging the orifices not used by plugs such as 42, 43 and 44.
  • the pressure-regulating pressure regulator comprises a fitted valve body 45 tightened in a bore 46 by means of three 0-ring seals 47, 48 and 49.
  • This valve body 45 itself comprises a bore 50 in which two pistons 51 are mounted and 52 rigidly connected together by a rod 53 and each provided with a segment constituted by an O-ring seal 54, respectively 55. At rest the double piston 51/52 is held in abutment against a screw 56 by a spring 57 s pressing against the bottom of the bore 46.
  • On the periphery of the valve body 45 are machined two annular chambers C3 and 59, the first between the seals 47 and 48 and the second between the seals 48 and 49.
  • the chamber 58 communicates with the space 50 by a nozzle 60 and is connected to the conduit 41 by a conduit 61.
  • the chamber 59 communicates with the part of the bore 50 situated below the pistons by a nozzle 62 and it is further connected to a conduit 63 leading to an outlet orifice 64 and to a conduit 65 leading to the availability safety device represented in FIG. 4.
  • This safety device is a valve made up of a rubber ball 66 held against its seat 67 by a spring 68 whose pressure can be adjusted by means of a screw 69 pierced with a axial hole 70.
  • the device is used for example as shown in FIG. 5. It is integral with a compressed gas tank 71 fixed under the head and communicating with the valves by the first inlet 36.
  • the second inlet 23 is connected to a dip tube in plastic material 72.
  • the head is fixed by means of a ring 73 set on the neck of a metal container 74 with the interposition of a seal 75.
  • the outlet orifice 64 opens freely inside the container.
  • the latter is provided with a removable cap 76.
  • the pressure regulator By means of the pressure regulator it is possible to maintain the pressure inside the container at a constant value, for example 1.1 bar when the pressure regulator is connected to the compressed gas tank, for example air or nitrous oxide, and this in a wide range ranging from at least 5 to 12 bars.
  • the stroke of the piston necessary to connect the chamber 50 and the nozzle 62 has been greatly exaggerated.
  • the double piston 51/52 appears in a state of perfect balance, it is possible to obtain a very slight displacement of this piston making it possible to ensure regulation.
  • the conduit 61 being connected to the compressed gas reservoir, the position of the double piston 51/52 is adjusted by means of the screw 56 so as to obtain the desired pressure in the container. The result obtained is surprising and unexpected.
  • valve body 45 of the pressure regulator could be omitted, the bore 50 then being made directly in the body 1.
  • Figures 6, and 8 illustrate, by way of example, three other possibilities of mounting the head and the reservoir on or in a container.
  • the container 77 is made of glass.
  • the reservoir 78 is of annular shape and surrounds the head 1 to which it is connected from the side. For this purpose, the lateral drilling is used, the plug 44 closing in this case the orifice 36.
  • the reservoir 78 has a projection 79 allowing it to be fixed to the notch in the neck 80 of the container. The whole is hidden by a cap 81 retained to the notch on the tank.
  • the container 82 is made of metal and it contains the compressed gas tank 83 fixed to a cylindrical cup 84 fixed by crimping 85 to the opening of the container.
  • the head 1 comprises, at its base, three nipples 86, 87 and 88 which extend each of the three original orifices and which have the dual function of holding the head on the container while ensuring the tightness necessary for this mounting and allow the head to be recovered on an empty container to be mounted on a new container.
  • the head 1 is provided with an annular compressed gas tank 89 extending below the head 1 by a ribbed central part 90 allowing the tank to be fixed on the neck 91 of a container metal or on the neck 92 of a glass container.
  • the reservoir 89 may be provided with a valve 93 allowing its recharging or the continuous use of the device by connection to a source of compressed gas or other suitable installation. In this case, the head, the tank and the container are recoverable.
  • the head is permanently fixed to a reservoir through which conduits connect the outlet orifice 64 and the inlet orifice 23 to orifices provided on the reservoir and minus of means of connection to an enclosure. In this case the head and the tank are recoverable.
