Definitions

  • the present invention relates to a valve for a sprayer comprising a container capable of containing at least one product to be packaged and dispensed and a propellant gas, the valve comprising a control rod movable axially in a valve body between a closed position of the valve and an open position thereof, the rod comprising channels respectively intended for conveying the propellant gas and the product towards a spray nozzle, these channels each opening at one end outside the portion rod engaged in the valve body.
  • the control rod slides through two seals respectively intended to insulate said channels in said closed position of the valve.
  • Valves of this type are known in which the aforementioned channels open to the outside of the rod portion engaged in the valve body by radially oriented orifices closed by the thickness of the seals when the control rod is in its closed valve position.
  • a disadvantage of these known valves is the relatively large driving stroke of the driving rod which is necessary to disengage said orifices and reach the open position of the valve.
  • the object of the present invention is to provide a valve of the aforementioned type which can open at the end of a drive stroke of the control rod which is less than that of known valves.
  • the invention advantageously allows, by playing on the way in which said crowns are shaped, to act on the degree of depression of the latter in the joints so as to be able to sequentially close said orifices and lastly isolate the conveying channel propellant gas towards the nozzle, in order to carry out a purge of the latter.
  • the invention also relates to a sprayer equipped with a valve as mentioned above.
  • valve 1 according to a first embodiment of the invention.
  • This valve 1 comprises a valve body 2 and a control rod 3 mounted to slide inside the valve body 2 between a closed position, corresponding to FIG. 1, and an open position (not shown).
  • a spring 4 is housed in the valve body 2 to return the control rod 3 upwards in the closed position of the valve.
  • the control rod 3 is capped with a head sprayer or push button 5 provided with a spray nozzle 6.
  • the valve body 2 has at its upper end an external annular boss 7 for its retention by crimping in a housing 8a of a cup 8 to be fixed on a container not shown , capable of containing a liquid product to be packaged and dispensed and a propellant.
  • the cup 8 is crimped onto a container not shown at its periphery at 8a with the interposition of a sealing washer 33, in a manner known per se.
  • the product is contained in a flexible bag and the propellant gas is contained in the container outside the bag.
  • the interior of the pocket communicates with the interior of the valve body 2 by a flexible tube not shown, force fitted on a nozzle 9 extending below the valve body 2 and provided with an anchoring cone 10.
  • the using a flexible bag to contain the product allows compressed air to be used as a propellant.
  • the pocket protects the product from contact with air so that it can be stored inside the container in good conditions and is only mixed with the propellant when it is expelled. Without departing from the scope of the invention, a substance capable of keeping in contact with the propellant can be added to the propellant gas.
  • a seal or sealing washer 11 is disposed in the bottom of the housing 8a and the valve body 2 is applied by its upper end edge 14 against the lower front face 11a of said sealing washer 11.
  • the control rod 3 is formed at its upper part with an internal part 3a cylindrical of revolution and with a sleeve 12 coaxial with the part 3a.
  • the sleeve 12 is internally grooved as shown in FIG. 2.
  • the ribs 12a formed between two consecutive grooves serve as spacers for positioning the sleeve 12 on the control rod 3.
  • the sleeve 12 is integral with the push button 5 in the example described and it passes through the bottom wall of the housing 8a of the cup 8 by means of a bore 8b and slides in leaktight fashion in the opening 13 of the sealing washer 11.
  • the control rod has an enlarged lower part 3b, formed integrally with the part 3a and able to move in the valve body 2.
  • the part 3b has, over part of its length, an external cylindrical surface 15 of revolution around the X axis.
  • a ring 16 forms radially projecting from the cylindrical surface 15 at the lower end of the part 3b.
  • This crown 16 is centered on the axis X, tapered upwards and has, in section in an axial section plane, a triangular shape as shown in FIG. 1.
  • the ring 16 provides an annular clearance with the body 2 allowing a passage of product from the interior of the end piece 9 to its tapered edge 17.
  • the latter applies, when the control rod 3 is at rest, to a seal sealing ring 18.
  • This has, in the example described, a square section and is applied sealingly by its radially outermost surface on the internal surface of the valve body 2 and by its radially outermost surface. internal on the cylindrical surface 15.
  • a ring 19 forming a spacer is inserted axially between the face of the seal 18 opposite the ring 16 and the sealing washer 11.
  • the internal upper part 3a of the control rod 3 is connected to the lower part 3b by forming a shoulder 20 extending perpendicular to the axis X, terminated at its periphery by an annular ring 21 centered on the axis X, tapered upwards and having in section in a section plane containing the axis X a triangular shape as shown in FIG. 1.
  • the annular ring 21 is applied by its edge tapered on the sealing washer 11.
  • the control rod 3 is traversed, over almost its entire length, by a blind bore 22 opening at the upper end of the part 3a and centered on the axis X.
  • the bottom of this bore 22 communicates by a recess 23 extending radially with an annular space 24 formed between the cylindrical surface 15 and the tapered part of the crown 16.
  • This annular space 24 constitutes an orifice, axially oriented, through which the product conveying channel opens to the outside of the portion of control rod engaged in the valve body.
  • the lower end edge of the control rod 3 is hollowed out at 25 to accommodate a plate 26 serving as a guide at the upper end of the spring 4.
  • the radial recess 23 extends in contact with the plate 26.
  • An annular boss 27 protrudes from the bottom wall of the valve body 2 to serve as a guide for the lower end of spring 4.
  • the upper internal part 3a of the control rod 3 defines with the sleeve 12 a plurality of channels 28 extending parallel to the axis X, communicating at their upper end with a conduit 29 leading to the nozzle 6 and at their lower end , by radial bores 30, with an annular space 31 formed between the external surface of the part 3a and the crown 21.
  • the annular space 31 constitutes an orifice, axially oriented, through which the channels for transporting the propellant gas open out to the outside of the control rod portion 3 engaged in the valve body.
  • the blind bore 22 opens at its upper end on a conduit 32 communicating with the nozzle 6.
  • the conduits 29 and 32 jointly feed a discharge orifice 6a of the nozzle 6 to project a mixture of product and propellant in the form of a aerosol in the direction of a Z axis perpendicular to the X axis.
  • a recess 35 is formed in the boss 7 of the valve body 2 for the passage of propellant gas through the valve body.
  • a corresponding recess 36 is formed in the ring portion 19 adjacent to the recess 35 and allows the propellant having passed through the valve body through the recess 35 to reach the crown 21.
  • valve 1 The operation of valve 1 is as follows.
  • the tapered edges of the crowns 16 and 21 rest respectively against the annular seals 18 and 11 and isolate the annular chambers 24 and 31 from the interior of the container.
  • the sleeve 12 presses by its lower end edge on the shoulder 20 and pushes part 3b of the control rod 3 into the valve body.
  • the sleeve 12 and the part 3b slide through the seals 18 and 11 without moving the latter in displacement, which makes it possible to precisely define the degree of depression of the rod leading to the supply of the annular chambers 24 and 31 with product and propellant gas.
  • the product may flow, under the pressure of the propellant gas into the container, inside the valve body, through the annular gap formed between the crown 16 and the seal 18 to gain, via the recess 23 and the blind bore 22, the conduit 32.
  • Propellant gas can circulate, through the recess 35 of the body valve 2 and 36 of the ring 19 forming a spacer, of the annular gap formed between the tapered edge of the crown 21 and the sealing washer 11, through the holes 30 and the channels 28, to the conduit 29 to gain nozzle 6.
  • valve 101 differs from the previous one by the fact that the valve body 102 is no longer constituted by a single piece but by the assembly of an upper part 102a and a lower part 102b, and by the fact that the rod control is formed by the assembly of a radially inner part 103a and a radially outer part 103b.
  • the part 103a is traversed axially by a blind bore 122 identical to the bore 22 previously described.
  • Crowns 116 and 121 respectively identical to the crowns 16 and 21 previously described, came integrally with the part 103b which is in the example described in the form of a ring fitted on the part 103a.
  • the plate serving as a guide for the spring 4 is in this embodiment integrally formed with the part 103a and defines a shoulder 37 on which the part 103b bears axially at the end of its fitting on the part 103a.
  • the upper part of the part 103a corresponds substantially to the single-piece embodiment of the sleeve 12 and of the part 3a of the previous embodiment.
  • An annular recess 128 runs axially through the part 103a from the upper end edge thereof to radial bores 130 by which it communicates with an annular space 31 identical to that of the previous embodiment. In this embodiment, it will be noted on examining FIG. 4 the absence of radial ribs in the annular recess 128.
  • the elements common to this embodiment and to the previous embodiment have been given the same reference numbers.
  • the ring serving as a spacer 19 is replaced in the example described by an annular rib 119 made integrally with the part 102a and forming radially protruding on the internal surface thereof.
  • the upper part 102a is perforated as before, at 35, for the passage of propellant gas.
  • the parts 102a and 102b of the valve body 102 are assembled after having successively introduced the annular seal 18 and the control rod into the part 102a.
  • the operation of the valve 101 is identical to the operation of the valve 1 previously described.
  • FIG. 5 shows a valve 201 according to a third embodiment of the invention.
