Definitions

  • the present invention relates to a metering valve, of the type adaptable to a pressurized container, intended to contain a product to be sprayed, containing a propellant gas in solution under pressure, and allowing by pressing a button to release a determined quantity of product.
  • a valve of this type is described in particular in French patent 1 287 373 in the name of Mr. Lucien Guillou for "Improvements to metering valves " .
  • the valve described in this patent is intended to operate when the container is in the upright position, with the opening at the top.
  • the subject of the present invention is in particular a valve of the above type, operating in the inverted position, and making it possible to dispense more precise doses, without variation of the quantity delivered on each expulsion until the bottle is exhausted, and also to allow filling the bottle in better conditions.
  • Valves intended for operation with the container in the inverted position are described in documents US-A-3,394,851 (Gorman) and FR-A-2,403,833 (Glaxo).
  • the device of the American patent is intended for an insoluble gas, such as nitrogen, contrary to the present invention.
  • the return spring of this valve is placed towards the outside of the container, which lengthens the outlet path of the product to be sprayed, and imposes larger dimensions on the valve, which limits its applications.
  • FR-A-2 403 833 the return spring of the valve is located in the bottom of the valve, and it follows that the filling of the measurement chamber can be hampered.
  • the subject of the invention is a valve of the type in question, in which the return spring of the valve is placed at the bottom of the valve, but in which perfect filling of the measuring chamber is ensured during the entire use of the container. .
  • the invention particularly relates to an improvement to the valve described in document FR-A-2 403 833, that is to say a valve intended to be mounted in the opening of a pressurized container, to contain a product to be sprayed containing a propellant in solution under pressure, and to expel precise doses of product when the container is kept in the inverted position with the opening down.
  • the valve comprises a valve body of tubular shape, said body forming at its upper part a measurement chamber disposed near the opening of the container, delimited by a wall of generally cylindrical shape, two radial walls constituted by an annular seal greater than central opening and a lower ring seal with central opening, and an axial valve stem extending through the seals and having an upper extension extending outside the valve.
  • the rod has an extra thickness between the joints making it possible to close the opening of the lower joint, the rod extending downwards by a thin part passing through the opening of the lower joint and a guide part, the upper part of the rod comprising an axial channel communicating with the outside via a passage, the passage being able by displacement of the rod, to come from one or the other of the sides of the upper seal.
  • Said body further forms at its lower part a tubular housing for a return spring bearing on the one hand on the bottom of said housing and on the other hand on a shoulder formed on the rod.
  • the improvement consists in that the thin part of the rod is formed by substantially radial ribs which are angularly spaced in a substantially regular manner, said ribs extending in the direction of the bottom of the housing which receives the return spring, to constitute the formed shoulder. on the stem; the aforementioned housing has angularly spaced longitudinal openings in a substantially regular manner and extending over substantially the entire height separating the bottom of the aforementioned housing and the lower seal of the measurement chamber.
  • the improvement also consists in that the number of the above-mentioned longitudinal openings is less than that of the above-mentioned radial ribs.
  • the valve according to the invention intended to be fixed in the opening of a container such as a bottle or the like, comprises a valve body 1 fixed in a capsule 2 with the interposition of an annular seal 3.
  • the capsule 2 is itself crimped onto the neck of a container, not shown, with the interposition of another seal, in a well known manner.
  • a container is intended to contain a liquid product, with a pressurized gas (called propellant) soluble in the product.
  • propellant pressurized gas
  • the operating principle of such a metering valve is well known. It is described in the patents cited above.
  • the valve body forms at its upper part a measurement chamber 13 and at its lower part a housing 30 for a return spring.
  • the words upper, lower, upper or lower relate to the right position of the container, with the opening upwards.
  • valve stem 4 AT the inside of the valve body is arranged a valve stem 4 of which a part 5 extends to the outside, through the seal 3.
  • This stem has an axial or longitudinal channel 6 opening at the outer end of the stem and communicating with a radial passage 7.
  • the rod 4 is pushed upwards by a spring 8 and comes to bear against the seal 3 by a shoulder 9.
  • the passage 7 opens above the seal (possibly in the seal, but not below) so that the bottle is closed, and the product under pressure cannot exit.
  • the rod 4 is extended in the interior of the container by an enlarged part or piston 11, for example of the same diameter as the shoulder 9, and an annular seal 12 is disposed at a certain distance from the piston, the central opening 31 of the gasket 12 corresponding to the diameter of the piston 11.
  • the container is turned over, placing the opening with the valve at the bottom.
  • a closed volume, or chamber 13 which contains a dose, the volume of which is precisely determined, of the product to be sprayed loaded with propellant dissolved under pressure.
  • the opening of the passage 7 appears in the chamber 13, and the content thereof is then evacuated by the passage 7 and the channel 6, under the effect propellant which is released as a result of the drop in pressure.
  • the rod 4 is released which is returned to its initial position by the return spring 8.
  • the chamber 13 is then opened. To reload the dosing chamber, keep the container upside down.
  • the product reaches the chamber 13 through at least one opening provided in the bottom of the valve body, below the seal 12.
  • the rod 4 advantageously extends by a thinned part 14 having for example a shoulder 15 for the support of the spring.
  • the rod 4 ends with a barrel 16 engaged between the turns of the spring and used for guiding and centering the rod 4.
  • the thinned part 14 has dimensions such that in the rest position, the piston 11 being released from the seal 12 , the product can easily reach chamber 13.
  • the thinned part 14 consists of several radial ribs 17a, 17b, 17c, 17d etc, of constant section or not and extending from the piston 11 to the shoulder 15.
  • each rib has the shape clearly visible in Figure 1.
  • This arrangement has the advantage of leaving an important passage for the product both during the initial filling of the bottle and during normal use.
  • the ribs 17 also maintain the opening of the seal if it were to swell under the influence of the product put into circulation.
  • the bottom of the valve body forms a housing 30 for the spring, and this housing has openings 19 extending over the entire available height, that is to say from a neighboring point.
  • the number of openings 19 being different from the number of the ribs 17, so as to always have at least one continuous clear passage, avoiding that 'there is a rib opposite each opening.
  • the valve stem 4 is in two parts: a first upper part 32 constituted by the external part 5 and the piston 11, and a second part 33 constituted by the thinned part 14, the shoulder 15 and the barrel 16.
  • the two parts thus formed are easier to manufacture, with greater precision, by avoiding shell molding.
  • the two parts can be assembled by any means: force fitting, with or without glue (as indicated by the dotted line 29), screwing, welding, etc.
  • spikes 25 are provided on the valve body 1 and / or on the spacer 23.
  • valve body 1 may have radial ribs 26 (left half of Figure 1) which mechanically strengthen the chamber, especially when it is very hollow, to expel large doses.
  • the ribs also serve to hold the seal 12 in place. By eliminating the deformation of the chamber, the presence of the ribs makes it possible to have more precise doses.
