Definitions

  • the invention relates to valves of the type known in the perfumery and cosmetic industries for the distribution under pressure of a liquid product.
  • the invention applies improvements to these valves which considerably extend the possibilities for their utilisation.
  • valves of the above type distributed through the industry are applied to control the emission in the form of an aerosol, or more or less in the form of very minute droplets of a liquid product (such as eau de cologne, toilet water, perfume, skin softening preparations, etc.
  • a liquid product such as eau de cologne, toilet water, perfume, skin softening preparations, etc.
  • This product is contained in a receptacle, onto which the valve is crimped, in a mixture with a propellant which is often a liquefied gas such as butane or one of the gases known under such names as freon, etc.
  • a satisfactory atomization is only obtained when the product and the propelling agent are mutually compatible and, further, are miscible one with the other in the utilization conditions in order to form a stable homogenous mixture.
  • the principal object of the invention is to improve a valve of the known type defined above in order to be able to make use of them likewise for the ejection under pressure of a product not mixed with a liquid propelling agent, the propellant being shut off, within the receptacle, in a separate capacity.
  • the valves so improved have greater possibilities for application in perfumery, in cosmetics, with drugs, etc.
  • Another object of the invention is to improve a valve of the known type simply by the addition of the smallest possible number of parts which can be made economically on a quantity production basis.
  • a supplementary object of the invention is to attain a valve of the known type improved by the addition of fining with said wall an enclosed chamber intended to contain a liquified fluid propellant, a sealed joint con necting said wall to an' upper part of said body. and flap valve means provided on said wall which is openable to permit propellant to pass from the enclosed chamber to the interior of said receptacle.
  • FIGS. 3 to 6 are enlarged detail views of four examples of a flap element forming part of an improved valve according to the invention.
  • FIGS. 7, 8 and 9 are part section views of three other examples of valves improved according to the inven- DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • This valve 1 is incorporated in a capsule 2 crimped onto a receptacle 3.
  • the valve 1 comprises generally tubular body 4, and a plunger tube 5 pressed into the lower part of the body 4 and extending to the bottom of the receptacle 3. I
  • a plunger 6 loaded upwards by a spring 7.
  • a longitudinal channel. 8 which communicates with a radial hole 9.
  • the hole 9 is blocked by a rubber seal 10 located at the bottom of the capsule 2 and gripping flexibly around the plunger 6.
  • the product contained in the receptacle 3 e.g. perfume plus a propellant, is displaced by the pressure which prevails in the receptacle, rises up through the tube 5, passes through the tubular body 4, and passes through the radial hole 9 into the duct 8 from which it is discharged.
  • a wall 11 extends around the greater part of the body 4 and defines an enclosed volume 12 about the body 4.
  • this wall is comprised by a tubular part making a sealed joint with the upper part of the body 4'by virtue of an external annular flange 13 passed into the capsule 2 and trapped between capsule 2 and the upper edge of the receptacle 3.
  • the flange l3 is joined in a manner forming a seal to the upper part of the body, by virtue of the capsule 2and theusual joints.
  • the wall 11 makes a sealing joint with the lower part of the body 4 or, more precisely, with the plunger tube 5 which can be integral with the body 4.
  • the wall 11 is provided with a base 14 pierced by an aperture through which the tube 5 is passed with an interference which is adequate to make this a sealed assembly.
  • the plunger tube 5 is an extension of the body 4 and that the wall 11 can also extend in part around the tube 5 as can be seen in the FIG. 1. It is easily appreciated that the wall 11 can be produced in the form ofa tubular part having an outer flange 13 and a pierced base 14, moulded as one piece in a plastics material.
  • the wall 11 is provided with a flap valve arrangement, identified with the general reference 15, which is displaceable outwardly relative to the wall 11 in order to bring the enclosed volume 12 into communication with the interior of the receptacle 3.
  • the flap valve arrangement 15 includes a transfer passage 16 pierced through the wall 11 and a ring. 17 in an elastic material, such as rubber for example, fitted around the tubular wall 11 on a level with the hole 16.
  • the ring 17 has at its upper end an external annular flange 18 which is passed into the capsule 2.
  • This flange l8 rests directly on the upper edge of the receptacle 3. It supports in its turn the flange 13 of the tubular wall 11 on which is laid a rubber sealing joint.
  • the wall 11 is intended to contain in the enclosed volume 12 a propelling agent constituted by the liquid phase of a suitable liquified gas.
  • This liquefied gas becomes partially vaporized and its vapor displaces out wardly the ring 17 of the flap valve 15. Passing through the hole 16, the vapor expands within the receptacle 3 until the pressures are balanced.
  • the plunger ti is depressed, the product contained in the receptacle 3 is set in motion by the pressure; at the same time a fresh vaporization of liquid occurs in the volume 12 which passes through the flap valve 15.
  • the product is propelled by the propulsive agent through tube 5, body 4, hole 9, and channel 8, but it is not in contact with the liquid phase of the propellant.
  • the propelling agent is in fact kept in the liquid state inside the wall 11, it only occupies a small volume; and it is vaporized as it is needed.
  • liquid propellant and the product should be two substances capable of forming a stable homogenous mixture. It is only necessary that the gaseous phase of the propellant does not readily dissolve in the product, as in this case all the liquid phase would vaporized rapidly at the speed of the solution of the gaseous phase in the product.
  • the known part of the valve 1 as described above can be used for the discharge under pressure of an homogenous mixture of product and liquified propellant. It sufficies to bring in just at the time of use, the tubular part 11 provided with the flap valve arrangement 15 for the improved valve 1 to be able to serve for the projection of a product which always remains separated from the liquid phase of the propellant. No change is made so far as the receptacle 3 is concerned. Further, no alteration is made to the known part of the valve 1, so that if the tubular part 11 and valve arrangement 15 are removed, it can'again serve for its initial use.
  • FIG. 2 shows another example of a valve 1A, improved in accordance with the invention, which is of the type filled under pressure.
  • the component parts which are identical to, or similar to those of the valve 1 are identified by the same references.
  • the upper part of the piston 6 carries an actuating push-rod 22.
  • the stroke of this latter in relation to the capsule 2 is fixed at a value 1 less than L in such a way that in normal use the piston 6 cannot block the orifice 19.
  • valve 1A is of a classic type known as a pressure charging metering valve to which the improvements in accordance with the invention add new possibilities for application.
  • a tubular part 11 furnished with a flap valve arrangement 15, the whole being suitable for introduction through the opening of a receptacle 3.
  • FIGS. 7, 8, 9 show variations of the embodiment of the tubular part 11 and of the means for its fitting on the body of a valve.
  • FIGS. 7 and 8 there is, starting from this base, an internal sleeve 30 having a duct 31 passing through it from end to end.
  • the free end of the sleeve 30 has a reduced diameter so that it adapts itself exactly in the lower aperture of the body 4.
  • FIG. 8 of the free end of the sleeve 39 has an enlarged bore in order that the lower part of the body 4 can fit exactly into the sleeve.
  • the plunger tube 5 is introduced into the duct 31, which is slightly expanded at its lower end.
  • the sleeve 30 has a considerably reduced height; it constitutes rather a reinforcement of the base 14.
  • This reinforcement of the base has an opening passing through it in such a way that the lower part of the body 4 fits exactly therein and protrudes beyond the tubular part 11. The plunger tube 5 is then pushed into the body 4.
  • FIGS. 7, 8, 9 contribute supplementary advantages.
  • the plunger tube 5 passes completely through the base 14.
  • This tube often has an irregular outer surface, carrying longitudinal striations caused during its extrusion.
  • the striations can be a cause of escape of the liquid phase of the propellant contained in the tubular part 11.
  • the plunger tube 5 passes through the base 14 and is fitted into the lower part of the body 4. This double assembly of the tube is far from easy to achieve on an automatic assembly machine; a single assembly is preferable for an assembly machine,
  • the part 11 is assembled with the body 4 and the plunger 5 is assembled either with the part 11 (FIGS. 7 and 8) or with the body 4 (FIG. 9).
  • the double assembly is eliminated and replaced by a single assembly.
  • valves which up to the present could only serve for the distribution of liquid products miscible with a liquified propellant can be rapdily modified to serve for the distribution of products which cannot be mixed with a liquid propellant.
  • This product can be a liquid, a foam, a paste, etc.
  • FIGS. 3 to 6 Variations in the form of the flap valve arrangement are shown in FIGS. 3 to 6.
  • therubber ring 17 has in front of the hole 16 a protrusion 23 of hemispherical shape which seats perfectly on the edges of this hole.
  • a circular groove 24 is cut in the wall 11; and the hole 16 is pierced through to the bottom of the groove 24.
  • Thering 17 has an internal bulge 25 suitable to come into contact with the edges of the groove 24.
  • a metal collar 26 is fitted on the outer face of the wall 11.
  • This collar 26 is equipped with a flexible bar 27 which extends longitudinally in front of the hole 16, where its free end is equipped with a protruberance 28 acting as an obturator for the hole 16.
  • the hole 16 pierced in the wall 11 is surrounded externally by a raised conical zone 29 which is terminated by a very narrow annular face.
  • the lower flexible part of a rubber ring 17 combines with that an-' nular face to play the part of a flap valve.
