Definitions

  • the subject of the invention is a valve making it possible to dispense a measured quantity of a product in a liquid medium, from a container where this product is enclosed in solution or suspension in a liquid having a high vapor pressure, which allows to drive it outside and as a general rule to spray it in the form of an aerosol.
  • valves are well known: they take the form of a double valve. They thus comprise a hollow body mainly consisting of a cylindrical casing of rigid material, closed by a cup which, as a general rule, also makes it possible to fix it on the container, and provided, on the other hand, with an orifice admission.
  • the intake port carries a intake tube if it is desired that, to expel the product, the valve, for convenience, be used in the high position, above the container; on the contrary, it is placed immediately upstream of the previous threshold if, to increase the precision, it is preferred to use it in the low position, container turned upside down.
  • control rod carries an axial discharge channel; it thus forms with the distributor a nozzle, the tube of which supplies a spray nozzle mounted on the head.
  • Each of the two seals which equip the thresholds of the chamber is generally a simple sliding seal, flat or lip, inside which the nozzle passes, made of a rigid plastic material. But for the valve to have a perfect seal at rest, it is then necessary that the seal of the external or posterior threshold is made of elastomer, the distributor carrying a shoulder which comes to bear thereon.
  • the seal of the internal or anterior threshold ordinarily plays a role only during operation, that is to say for a limited time. It therefore does not require such perfect sealing; on the other hand, it is in permanent contact with the liquid: this is why it is sometimes an integral part of the casing, despite the rigidity of the material used to manufacture it.
  • the two seals are immobilized using a waterproof sleeve made of an inexpensive semi-rigid plastic material, the thickness of which can also be varied to modify the internal volume of the chamber without affecting a complex piece.
  • valves in question are filled by intrusion or break-in, that is to say that the tube is put in place on a pump which then injects the necessary quantity of product, in the liquid state, under strong pressure: the latter then discards at least one of the seals to find a channel which allows it to fill the container.
  • intrusion or break-in that is to say that the tube is put in place on a pump which then injects the necessary quantity of product, in the liquid state, under strong pressure: the latter then discards at least one of the seals to find a channel which allows it to fill the container.
  • the above threshold advantageously forms a guide bearing for the dispenser which is thus free from undercut therefore also from any lateral seam detrimental to the seal.
  • this front threshold and the socket will be made in one piece.
  • the body of the valve of FIG. 1 consists of a casing 1 carrying a socket 2 and closed by a cup 3 enclosing a seal 4.
  • the housing is made of a rigid resin, such as a polyacetal. At its lower part, its wall narrows by a conical bearing 1 a to form without undercut an anterior chamber 1 b carrying a pick-up tube 5.
  • the sleeve is formed of a semi-polyethylene rigid. Its side wall 2 a , provided with a flange 2 b , is extended at its lower part by a conical veil 2 c carrying a flange 2 d to form the front threshold 6. It is freely adjusted in the housing and, at the tolerances, its conical web 2 c comes along the span 1 a .
  • the elastomer seal 4 acts as a rear sill.
  • the cup 3, metallic, and set at 3 a on the casing, thus immobilizes it with the socket, taken by its flange 2 b in a housing provided at the upper part of the casing, defining an airlock chamber 7; its skirt, carrying a seal 8, will be crimped again, in 3 b , on the container 9.
  • a spring 10 is mounted, then the nozzle 11, formed in turn of polyacetal.
  • This comprises a plug 12, extended through the joint 4 by a tubular rod 13, the central channel 13 a of which , in the present case, opens at its lower part by a lateral orifice 13 b outside the valve, at its axial outlet through an orifice 13 c capable of supplying the spray nozzle of the push button nozzle, not shown, which adapts to it.
  • the plug 12 carries a flange 12 a , the upper shoulder of which bears in tight seal on the seal 4. Its lower part is cylindrical, except that grooves 12 b form a passage inside the threshold 6, and that its end serves as a support for the spring 10, without there being undercuts.
  • the passage open under the posterior seal closes in the first place, restoring the container sufficient tightness; then the anterior passage opens, allowing liquid to enter the chamber under the effect of the depression thus created.
  • valve of FIG. 2 is shown assembled and during filling, placed on the nozzle of a pump 14, nozzle pressed in.
  • the main difference is that, intended to be used upside down, it has no intake tube but at least one inlet 15 placed in the chamber 1b of the spring closest to the chamber 7 of the airlock.
  • the side wall 2a of the sleeve used is thicker, so that the volume of the chamber is lower, and devoid of flange but taken over its entire height and therefore may be in two parts, while the collar 2 d is replaced by a simple oblique lip.
  • the bearing surface 1 a is formed by a number of bosses 1 c bearing on the web 2 c , but which are separated from the internal grooves; these bosses allow the lip edge to play, so that the seal is obtained without tightening.
  • the wall of the casing bears on the external face of its reinforced upper part, a groove 1 d which opens on the one hand on the side of the joint 4, by slots, on the other hand on the upper face of the joint 8 for assembly on the container.
  • the valve For filling, once the valve has been adapted, by its tube 13, on the pump 14, the latter injects the liquid there.
  • the pumping pressure then has the effect of driving the nozzle back into a position identical to the spraying position, allowing the liquid to penetrate rather by the tube than along the joint 4 in the direction of the chamber 7 but also closing the passage along the threshold seal 6.
  • the rise in pressure in the chamber does not significantly deform this threshold because the bearing web 2 c rests on the surface 1 a .
  • the liquid can hardly flow along this seal but, deforming the seal 4, infiltrates in the direction of the groove 1 d to push the seal 8 inward, which allows it to penetrate quickly , according to the arrows, in container 9.
