Definitions

  • the invention relates to a metering valve for liquid products, operating as a pump.
  • a double valve system allows the expulsion of the contents of this chamber when the user pushes the pusher - the first lower valve is then closed and the second valve open, then the filling by suction of this chamber when the pusher is released and qu 'it rises under the action of a spring - the first lower valve then being open and the second valve closed.
  • Document EP-0 189 549 provides, in a metering pump, for placing in the container a filter for bacterial germs. But on the one hand such a filter has no action against the oxygen of the ambient air, on the other hand it is arranged inside the container and it can be wetted by the liquid contained in the container .
  • the second valve has a lip of a floating piston displaceable in front of an axial piston hole linked to the pusher, the seal is ensured when the pump is at rest, even if the container is laid down or turned over.
  • the valve When the second valve is constituted by a ball, the valve is not likely to remain open during the operation of filling the chamber. But if the container is lying, the valve opens and no longer seals at the pusher. As a result, the liquid may leak.
  • document FR-2 048 263 has in the pusher, at the level of the pipe, liquid outlet, an additional ball and spring valve, the implementation of which requires a certain number of additional parts, the cost of which is not negligible.
  • a first object of the invention is to provide a metering valve which avoids the risks of deterioration of the liquid product by atmospheric pollution.
  • Another object of the invention is to propose a metering valve which does not exhibit any defect in the metering of the product or in sealing in the event of a change in the position of the container.
  • FIG. 1 shows the body 15 of a rigid container containing the liquid to be dispensed.
  • the neck of this container is capped by a cup 4, with the interposition of a seal 42.
  • the cup 4 has a central passage in which freely slides a substantially cylindrical axial piston 3 and having a bulged part 31 capable of coming in stop under a narrowing 41 of the central passage of the cup 4.
  • the axial piston 3 Near its upper end, the axial piston 3 has an annular widening 32 capable of coming into abutment on the narrowing 41.
  • the axial piston 3 has a central bore 17 opening only at its upper end in the form of a valve seat 20 intended to receive a ball 19 acting as an upper valve, that is to say a second valve for the control of the dose of liquid delivered.
  • the upper end of the axial piston 3 is capped by a pusher 2 having a blind central bore 22 facing the valve seat 20, and a channel 18 for outlet from the liquid to be dispensed.
  • This pusher has a skirt capable of sliding freely in a cylindrical part of the cup 4, or around this cylindrical part.
  • a sheath 16 is snapped onto the cup at the seal 42.
  • This sheath consists of three cylindrical parts and a nozzle, also cylindrical, which are of decreasing diameters.
  • the first part 43 of the sleeve 16 extends a little below the cup 4 and defines between its bottom 44 and the cup 4 a space in which is housed a filter 5 of annular shape.
  • the bottom 44 is pierced with holes 12 which communicate the outside and the inside of the container 15.
  • the second part 45 of the sleeve 16 defines a metering chamber 13.
  • the third part 46 of the sleeve 16 guides a spring 8 and its bottom comprises a valve seat 21 for a ball 9 playing the role of a lower valve, c that is to say a valve for admitting the liquid into the metering chamber 13.
  • the sleeve ends in a nozzle 47 on which is fixed a dip tube 14 whose free end is found at the bottom of container 15.
  • the spring 8 the lower end of which is guided by the sleeve 16, has its upper end applied under the lower end of the axial piston 3. It is compressed when a user presses the plunger 2, and returns the axial piston 3 and pusher 2 up when the pressure on the pusher is released.
  • a diametral hole 6 which passes through the central bore 17 and can thus establish a communication between this bore 17 and the chamber 13.
  • the diametral hole 6 crosses the axial piston 49 of reduced diameter, between the bulged part 31 and a lower annular widening 48 which serves as a support stop for the spring 8.
  • a floating piston 1 which slides on the one hand on the zone 49 of the axial piston 3, on the other hand on the second part 45 of the sleeve 16.
  • the floating piston 1 has a cylindrical ring 50 capable of being applied under the cup 4.
  • the floating piston 1 On the zone 49 of the axial piston, the floating piston 1 carries a lip 7 capable of closing off the two ends of the diametrical hole 6.
  • the operation of the metering valve according to the invention is as follows, starting from the rest position of FIG. 1.
  • the swollen part 31 of the axial piston 3 arrives at the floating piston 1 and drives it downwards, driving the liquid from the chamber 13 through the hole 6, the bore 17 and the channel 18.
  • outside air is admitted into the chamber 13, above the floating piston 1, passing between the skirt of the pusher 2 and the cylindrical part of the cup 4, then between the axial piston 3 and the cup 4.
  • the widening 32 of the axial piston 3 reaches the narrowing 41 of the cup 4, a dose of liquid has been delivered through the channel 18.
  • the ball 19 drops back onto its seat 20.
  • the filter 5 passed through by the air which enters the container can be sterilizing to stop bacteria and keep the product sterile. It can also be designed to capture oxygen from the air in case the liquid product of the container must be protected from oxidation. Finally, it may, in general, be able to stop any external pollution and allow only perfectly pure air to enter the container.
  • This filter can be made of paper, fabric, plastic, a material impregnated with a liquid, and generally, any material capable of stopping the undesirable component (s) contained in the air.
  • FIGS. 4 and 5 there is shown a metering valve according to a second embodiment of the invention.
  • This valve generally has the same elements as the valve described with reference to FIGS. 1 to 3.
  • the neck of the container 115 containing the liquid to be dispensed is capped by the cup 104 with the interposition of an O-ring seal 160.
  • This cup 104 carries on its face external to the container 115 a cylindrical part 140 and on its side facing the inside the container 115 a skirt 141 disposed against the internal face of the neck of said container.
  • the cup 104 also has on its external face a wall 142 forming a housing for the installation of a filter 105. Holes 143 drilled in the cup 104 at the bottom of the housing for the filter 105 allow the communication of the external space in the cup with the inside of the container 115.
  • the cup 104 carries, snapped inside the skirt 141 shaped for this purpose, a sheath 116.
  • this sheath has three cylindrical parts and a nozzle which are of decreasing diameter.
  • the first part 144 is shaped externally to snap into the skirt 141 and internally with a shoulder for the establishment of a plate 150. Holes 148 pass through the first part 144 below said shoulder.
  • the second part 145 of the sleeve 116 defines the metering chamber 113.
  • the third part 146 guides the spring 108 and has at its bottom the lower valve for admitting the liquid into the metering chamber formed by the valve seat 121 and ball 109.
  • the dip tube 114 is fixed inside the end piece 147 present below the lower valve.
  • the plate 150 carried by the first part 144 of the sleeve 116 is crossed axially by a cylindrical end piece 151 disposed in the axis of the cylindrical part 140 of the cup 104.
  • the axial piston 103 is disposed inside said cylindrical part 140 of the cup 104 and said end piece 151 of the plate 150.
  • the axial piston 103 has an annular widening 132 against which an O-ring seal 133 is arranged intended to be pressed against the internal surface of the cylindrical part 140 in order to close the upper end of the cup 104.
  • the axial piston 103 has an extension by which it is fixed by snap-fastening between two axial cylindrical walls 134 and 135 of the pusher 102.
  • the internal cylindrical wall 135 is shaped to form a valve seat 120 intended to receive the ball 119 forming the upper valve or second valve of the metering valve.
  • the plunger 102 has a blind axial bore 122 opposite the valve seat 120 and a channel 118 for output of the liquid to be dispensed.
  • the axial piston 103 In the vicinity of its lower end, the axial piston 103 has a reduced diameter zone 149 arranged between two bulges.
  • a floating piston 101 is mounted on this zone 149 of reduced piston diameter in order to slide on said zone 149 and on the internal face of the second part 145 of the sleeve 116.
  • This floating piston has a cylindrical ring 152 capable of being applied against the lower end of the end piece 151 of the plate 150 and a lip 107 capable of closing off the diametrical hole 106.
  • the spring 108 is applied to the axial piston 103 under the lower shoulder delimiting said zone 149 of reduced diameter.
  • FIGS. 4 and 5 The valve of FIGS. 4 and 5 is completed by a plug 170 held on the pusher by a ring 172 to which it is connected by a link 171.
  • This plug 170 is capable of adapting to the dispensing end piece of the pusher 102 in order to preserve the latter from any pollution when the valve is not used.
  • the plug 170 also closes the outlet channel 118 avoiding defusing the valve between two uses.
  • Figure 5 shows the valve of Figure 4 during liquid distribution.
  • the plug 170 no longer closes the dispensing end piece of the pusher 102 and the latter has been moved downwards.
  • the movement of the pusher 102 downwards drives the axial piston 103 as previously, which in a first step causes the diametrical hole of the lip 107 to exit the floating piston 101 and in a second step drives said floating piston 101 towards the bottom of the room 113.
  • the blind bore 122 comprises a shoulder 123 at a level lower than that where the outlet channel 118 opens.
  • the axial piston 103 is free to go back up in order to return to the rest position of FIG. 4.
  • the ball 109 is lifted from its seat 121 and the liquid in the container 115 is allowed to enter the chamber 113 which creates a vacuum in the container tending to suck outside air through the orifices 148.
  • the filtered outside air which is located above the floating piston 101 then passes into the container 115.
  • the metering valve of FIGS. 4 and 5 has two important advantages over that of the preceding figures: the presence of the O-rings 160 and 133 ensures total tightness; positioning the filter 105 outside the container and the tray 150 in the sheath 116 makes it possible to avoid any contact between the liquid and the filter, which protects the latter and increases its effective life, especially when the liquid is sugar.
  • the valve according to the invention in addition to filtering the outside air, has the advantage of having a system of valves preventing leaks of liquid product when the container is coated, for example. Indeed, with a ball 19, 119 on a valve seat 20, 120 and a floating piston 1, 101 whose lip 7, 107 closes the diametrical hole 6, 106 of the axial piston 3, 103 the risk of seeing the outside air entering through the axial bore 17 is removed.
