Definitions

  • the invention relates to a push-in valve for dispensing in the sprayed form a liquid contained in a flexible bag, itself arranged inside a container maintained under gas pressure.
  • the valve, object of the invention is of the type which includes a valve body intended to be fixed in a cup, closing the container, with the interposition of a sealing washer between an open front end of the valve body. and the cup, and a control rod capable of sliding in the valve body between a rest position and an open position, the valve body forming a chamber which is isolated from the outside when the rod is at rest and cooperates with the sealing washer so as to close said chamber, the rod being held in this rest position by elastic return means, an additional gas intake orifice being provided in the side wall of the valve body, the body being provided, at its lower part, with a means for fixing the flexible bag containing the liquid.
  • FR-A-2 415 250 shows a valve of this kind for the dispensing, with mixing, of two products contained respectively in a flexible bag and in a container surrounding the bag.
  • the mixing of the products to be dispensed takes place in a chamber which is located in a push button above the valve.
  • the design is relatively complex.
  • a valve for dispensing in spray form a liquid contained in a flexible bag as defined above, which, while making it possible to mix the liquid and the propellant gas in the chamber of the valve body, avoids the entry of pressurized gas from the container into the flexible bag containing the liquid, as well as the flow of liquid to the container ;
  • the arrangement of such a valve has the advantage of allowing the use of the container which it equips in all positions but, unfortunately, it does not allow the chamber to be purged from the valve body, before and after each distribution of '' a dose of a liquid / gas mixture.
  • the object of the present invention is to propose a valve which does not have these drawbacks.
  • a valve for the dispensing in sprayed form of a liquid contained in a flexible bag itself disposed inside a container maintained under gas pressure comprises valve means able to put the flexible bag into communication with the chamber when the rod is pressed in, and to isolate said pocket from said chamber when the valve is in the rest state, these valve means being controlled by the displacement of the rod, and being able to establish said communication between the pocket and the chamber only after a stroke of a determined distance from the control rod, so that before and after each distribution of a dose of a liquid / gas mixture the chamber is purged by a breath of gas only.
  • the valve stem protrudes through an opening in the cup and is capable of sliding in leaktight manner in the sealing washer, this stem comprising a blind bore opening to its end remote from the valve body, while a transverse orifice is provided in the wall of the rod to open into the blind bore and, outside, at the sealing washer when the rod is in position rest, said transverse orifice then being closed by this sealing washer;
  • the end of the rod located in the valve body is provided with an extension suitable for cooperating with a passage between the chamber of the valve body and the flexible bag so that in the rest position of the valve stem, the passage is closed by the extension, while when the valve stem is when pressed, communication is established between the valve body chamber and the flexible bag.
  • the extension may consist of a pin, while a second sealing washer is provided in the bottom of the valve body, the aforesaid passage being constituted by the central opening of the washer leaktightly crossed by the pin, which comprises a longitudinal channel which communicates, at its lower end, with a transverse channel opening onto the external surface of the pin and, at its other end, with a passage provided in the valve stem and opening into the chamber of the valve body, the outlet of the lower transverse channel located to the right of the second sealing washer and being closed by this washer when the rod is in the rest position, the pin and the sealing washer constituting said valve means.
  • the thickness of the second sealing washer is chosen so that when the rod is pushed in for opening, the orifice located towards the lower end of the blind channel of the rod between in communication with the valve body chamber before the transverse channel located in the lower part of the pin comes into communication with a nozzle and the flexible bag, which makes it possible to purge the valve body chamber in a intermediate insertion position of the valve stem.
  • the pin is fitted into a recess provided at the end of the rod located in the valve body.
  • the passage for communication between the chamber of the valve body and the flexible bag is provided in the valve body, while the extension of the valve stem has an intermediate zone of diameter smaller than that of the passage and an end zone of sufficient diameter to close the passage, the assembly being such that when the valve stem is pressed, the intermediate zone is at the level of the passage and establishes communication between the flexible bag and the chamber of the valve, while when the valve stem is in the rest position, the end zone is at the passage and cuts off all communication.
  • the extension may consist of a coaxial cylindrical element fixed at the end of the valve stem and the end of which faces the flexible bag is provided with an overmolding of elastomeric material constituting the said end zone.
  • extension and the valve stem form a single piece.
  • the end zone of the extension can advantageously have a bell shape, with a relatively thin and flexible wall, the concavity of which faces the flexible pocket.
  • valve means of the valve comprise a valve preventing any communication at rest between the pocket and the chamber of the valve body, the opening of this valve being controlled by the valve stem when it is pressed.
  • the valve can be independent of the valve stem and rest against a seat, formed by a second sealing washer, under the action of a return spring, the seat being provided with a central passage, and the valve being located on the side of the seat opposite the valve stem, the latter comprising a clean extension finger to pass through the central passage and to move the valve away from its seat when the valve stem is pressed.
  • the stroke of the rod necessary for the opening of the valve is advantageously greater than that necessary to bring the orifice of the blind bore of the valve rod into communication with the chamber located inside the valve body.
  • the invention also relates to a container containing a flexible bag in which there is liquid to be sprayed, maintained under gas pressure contained in the container, the latter being characterized in that it comprises a dispensing valve as defined previously.
  • Figure 1 of these drawings shows, in partial vertical section, a gas pressure container, equipped with a valve according to the invention, in the rest or closed position.
  • Figure 2 shows the valve of Figure 1 in the intermediate purge position of the valve body chamber.
  • Figure 3 shows the valve of Figure 1 in the open position.
  • Figure 4 illustrates an alternative embodiment of the valve with valve independent of the rod.
  • Figure 5 shows, in axial section, a variant of the valve of Figures 1 to 3, in the closed or rest position.
  • Figure 6 shows, in axial section, another variant of the valve of Figures 1 to 3, at the start of opening.

  • the container consists of a metal can, of cylindrical shape, the bottom of which is provided with a hole fitted with a valve making it possible to fill and recharge the container with pressurized gas, in particular with compressed air.
  • the container may also consist of walls of hard thermoplastic and have any shape and be manufactured, for example, by extrusion blow molding or injection.
  • a valve 8 is fixed in the cup 6.
  • This valve 8 comprises a valve body 9 of generally cylindrical shape, around which is crimped a kind of sleeve 10 provided in the center of the cup, the upper end of the sleeve 10 having an opening central 11 provided in a cap 12 of the sleeve.
  • a sealing washer 13 is interposed between the open front end of the valve body 9 and the internal surface of the cap 12 of the sleeve 10.
  • the valve 8 can also be fixed by any other means, for example by screwing, snap or bonding through an intermediate piece.
  • the valve 8 also includes a control rod 14 capable of sliding in the valve body 9 between a rest position shown in FIG. 1 and an open position shown in FIG. 2.
  • valve stem 14 projects, through the opening 11, through a part 15 surmounted by a push button 16, which comprises channels and a dispensing nozzle 17.
  • the part 15 of the rod has a blind bore 18 opening at its end remote from the valve body 9.
  • a transverse orifice 19 is provided in the wall of the rod 14. This orifice 19 opens into the blind bore 18 and, outside, at the sealing washer 13 when the rod 14 is in the rest position.
  • Elastic means formed by a helical compression spring 20 are provided between a stop zone of the valve body 9 and a stop zone of the rod 14 to maintain this rod in the rest position illustrated in FIG. 1.
  • the spring 20 bears against a second sealing washer 21 which is applied against a shoulder 22 constituting the bottom of the body 9.
  • the central opening of the washer 21 constitutes a passage p between the chamber C and the pocket 2.
  • a nozzle 23 extends the body 9 towards the bottom 3 of the container.
  • the flexible pocket 2 is tightly engaged around this nozzle 23, which constitutes a means of fixing said pocket.
  • the nozzle 23 communicates with the interior chamber C of the body 9.
  • the valve stem 14 has a base 24, of larger diameter than the part 15, located in the body 9.
  • This base 24 has a diameter less than the internal diameter of the body 9 so that a sufficient radial clearance exists between the cylindrical outline of this base 24 and the internal surface of the body 9 for the passage of the gas and the liquid to be sprayed.
  • the end 25, located in the valve body 9, of the rod 14 is arranged in the form of a cylindrical projection of diameter smaller than the base 24, and around which is engaged one end of the spring 20.
  • This end 25 has a bent passage 26 opening, at one end, on its outer surface and, at its other end, substantially in the axial direction, in a recess 27 provided in the bottom of the projection 25 and open in the direction of the nozzle 23.
  • the end 25 of the rod 14 is provided with an extension pin 28, coaxial, in the direction of the nozzle 23.
  • the pin 28 sealingly passes through the central passage p, of the washer 21, when the valve is at rest ( Figure 1).
  • the pin 28 has a longitudinal channel 29 opening axially at its upper end so as to communicate with the channel 26.
  • the channel 29 does not open axially at its lower end but communicates with a transverse channel 30 opening on the outer surface of the pin.
  • the pin 28 can be force-fitted into the recess 27.
  • the fixing of the pin 28 to the rod 14 can be completed by welding or by bonding.
  • the assembly is such that when the rod 14 is in the rest position, for example when the shoulder formed by the base 24 is in abutment against the sealing washer 13, the transverse channel 30 is located in line with the washer seal 21, and is therefore closed.
  • the pin 28 and the sealing washer 21 form valve means.
  • An orifice 31 constituting an additional gas intake is provided in the side wall of the body 9.
  • the assembly is further provided so that, when the rod 14 is pushed in, under the effect of a pressure exerted on the button 16, the transverse orifice 19 escapes from the washer 13 and opens into the chamber C limited by the body 9 before the transverse channel 30 opens in the nozzle 23.
  • the container being, for example, held head up.
  • the transverse orifice 19 communicates with the chamber C of the valve body, while the transverse channel 30 opens in the nozzle 23.
  • Liquid from the bag 2 can pass through the channels 30, 29 and 26 to reach the chamber C which constitutes a mixing chamber between the liquid, and the gas which arrives through the orifice 31.
  • the mixture thus formed escapes through the orifice 19 towards the nozzle 17 and is sprayed into the atmosphere.
  • the liquid contained in the bag 2 is isolated from the gas of the container, the latter can be used in any position and not only head up as indicated above.
  • the fact that in the rest position the liquid in the bag 2 cannot pass into the container makes it possible to avoid spraying a jet of liquid at the nozzle 17, at the place of a fog.
  • it is possible, during a spraying to pass from one position to another, in particular by passing horizontally, and to guarantee a constant quality of spray.
  • the thickness of the sealing washer 21 is chosen such that during part of the driving stroke of the rod 14, the transverse channel 30 remains closed by the washer 21 while the transverse orifice 19 communicates with the chamber C. Under these conditions, during this intermediate phase illustrated in FIG. 2, pressurized gas coming from the container and passing through the orifice 31 can escape through the transverse orifice 19 by purging the chamber C.
  • the transverse channel 30 When the insertion of the rod 14 is sufficient to reach the position illustrated in FIG. 3, the transverse channel 30 then opens into the nozzle 23 and allows the liquid contained in the pocket 2 to flow into the chamber C to be driven by the propellant and be sprayed through the nozzle 17.
  • the thickness of the washer 21 combined with the judicious arrangement of the different channels and dimensions of the elements, makes it possible to obtain a sequencing of the respective opening of the orifices with a purging effect for an intermediate position (FIG. 2) between the closed position ( Figure 1) and the fully open position ( Figure 3).
  • this arrangement allows purging of the chamber C before and after each distribution of a dose of a liquid / gas mixture.

  • a central passage p is defined by orifices provided in the bottom of the body 209 and in the washer 221, orifices which are superimposed.
  • the valve stem 214 is extended, in the direction of the plate forming the valve 232, by a finger 236 of sufficiently small diameter to cross, with sufficient clearance, the passage p.
  • the distance d between the lower edge of the orifice 219 and the lower face of the washer 213 is less than the distance D between the lower end of the finger 236 and the plate of the valve 232 in the closed position (d ⁇ D).
  • the valve 232 closes the passage p and cuts off all communication between the pocket 202 and the chamber C, which is in communication through the orifice 231 with the container containing the gas under pressure.
  • the gas under pressure cannot penetrate into the bag 202 and, conversely, liquid from the bag 202 cannot flow towards the chamber C and, through the orifice 231, into the container containing the gas.
  • the liquid in the bag 202 can then pass into the chamber C, mix with the gas to form a mist which escapes through the orifice 219 and the channel 218 for spraying.
