Definitions

  • the present invention relates to vaporizer valves of the type which are mounted in the opening of a container, such as a bottle or an aerosol can to extract the content and spray it while atomizing it; the word "valve” here comprising both hand-operated pump systems and systems using a propellant gas housed in the container, soluble or not in the liquid to be sprayed.
  • the invention relates to a device allowing the operation in all positions of a valve intended to operate in a single determined position (straight position), that is to say the use of the vaporizer both in the straight position as 'in reverse position.
  • the device is particularly suitable for valves intended to be mounted on containers with a narrow opening.
  • the device of the invention is particularly suitable for systems comprising a pump, actuated by the user's finger.
  • a device allowing the operation (both in inverted position and in upright position) of an aerosol valve intended to be crimped in the neck of a container, said device being intended to be interposed between the inlet end of the valve and a dip tube, this device comprising two chambers in series aligned on the axis of the valve, separated by a channel having a mouth in each chamber, said channel being in communication with the suction zone of the valve, each chamber comprising a valve controlled by gravity on the mouth of said channel, the valve being closed when the mouth is placed downwards, the chamber closest to the valve being elsewhere in communication by its end opposite to the mouth of the canal with an area outside the valve and close to the valve and the chamber furthest from the valve being moreover in communication by its end opposite to the mouth of the channel with said dip tube.
  • Such a device has interesting applications, but is difficult to manufacture and assemble.
  • the present invention relates to a simplified advantageous structure for the manufacture of such a device.
  • the device comprises three parts of generally tubular shape mounted concentrically, an outer sleeve which can receive the body of the valve, a tubular part which can engage on the inlet end of the valve and a socket defining the chambers with said tubular part and comprising said channel.
  • the sleeve comprises a part molded to a width greater than its width mounted in the device, this part being tightened during assembly of the device, by introduction into the tubular part, the tightening causing closing a room. This arrangement makes it possible to introduce a ball into the chamber, before closing this chamber by completely inserting the sleeve into the tubular part in its place.
  • the device is adapted to a valve 1 by means of a sleeve 2.
  • the valve is intended to be mounted in a conventional manner in the neck of a container, not shown, by means of a crimped capsule. on the edge 1a of the valve.
  • the valve can be of any type: pump, valve, metering or not. In this example, it is a valve of generally tubular shape, of small diameter, allowing it to be placed in the neck, or neck of bottles or narrow cans.
  • the invention applies to all types of valves, narrow or not, but it finds a particularly advantageous application in the case of narrow valves.
  • each chamber has another opening, opposite the mouth of the channel, l opening 14 for chamber 11 and opening 15 for chamber 12.
  • a small ball respectively 11a and 12a providing a valve function with the corresponding mouth 11b, 12b of the channel, these mouths forming valve seats.
  • small ball is meant here a ball with a diameter substantially less than 4 mm, for example of the order of 2 mm or less.
  • balls of diameter greater than or equal to 4 mm without which, the balls risk being entrained by the current of fluid, before being plated on their seats. This possibility of using small balls is offered by the shape of the chambers in accordance with the present invention, as explained below.
  • an orifice 16 communicating with the inlet 17 (or suction zone) of the valve 1.
  • the opening 14 of the chamber 11, the closest to the valve, is in communication with the interior zone 18 of the container close to the neck (at the top, when the container is in the standing position when not in use) and the opening 15 is in communication with the dip tube 3.
  • This region communicates with the chamber 11, but the latter is closed downwards by the valve formed by the ball 11a resting on the seat 11b. If the interior of the container is under pressure, thanks to a propellant fluid, this pressure is applied to the valve 11a, and keeps it closed. If the inside of the container is not under pressure, it is the suction of the valve which keeps the valve closed.
  • the device If the device is operated in the inverted position, it is then the region 18 which is immersed in the product to be expelled by the valve, while the end of the dip tube is in a gaseous atmosphere.
  • the valve being returned, it is the valve 12a, 12b which is closed while the valve 11a, 11b is open, and thus the device still functions as desired.
  • each chamber 11, 12 is formed with a bowl 11c, 12c opposite the entrance to the channel 13. Under these conditions, under the effect of gravity, one of the balls closes a valve and the other ball rests in the bottom of its bowl, away from the flow of fluid which could lift it and press it against the seat.
  • the invention relates to means for enabling industrial production under economically favorable conditions.
  • the device according to the invention consists, apart from the valve 1 and the dip tube 3, of the two balls and of three molded plastic parts.
  • a first part is constituted by the sleeve 2, in which one comes to engage the valve.
  • a circular chamber 21 At the height of the sleeve which corresponds to the base of the valve, there is provided a circular chamber 21, from which at least one internal groove 22 extends to the end of the sleeve to ensure communication with the interior space 18 of the can, but outside the valve.
  • two such grooves 22, 22 ′ have been provided.
  • a tubular part 4 is housed inside the sleeve 2, and is threaded onto the end piece 1a of the valve 1, in place of an external dip tube.
  • This part comprises a transverse partition 41, separating a volume comprising the valve from a volume comprising the valve chambers.
  • the partition 41 is located at a distance from the end of said tubular part 4, slightly greater than the length of the end piece 1a of the valve 1.
  • the partition 41 defines with the end of the end piece of the valve the zone inlet or suction 17 of the valve 1.
  • the tubular part 4 is formed, at this zone, with an opening 42 communicating the interior of the part, that is to say say zone 17, with the outside where a longitudinal groove 43 is formed extending to another opening 44 at the orifice 16 opening into the channel 13 between the two chambers.
  • the tubular part 4 also comprises a longitudinal groove 45 extending from the upper end of the part, up to the level of the chamber 11 with which it communicates by an opening 14.
  • a longitudinal groove 45 extending from the upper end of the part, up to the level of the chamber 11 with which it communicates by an opening 14.
  • a socket 5 completes the device. It comprises a main part defining the channel 13 and the two valve seats 11b and 12b.
  • the valve seat 11b and the partition 41 of the tubular part define the chamber 11.
  • the valve seat 12b and a secondary part 51 of the socket 5 define the chamber 12.
  • the main part is formed with a circular groove 49 into which opens out the orifice 16, as well as the opening 44. Thanks to this circular groove, the relative orientations of the sleeve 5 and of the tubular part 4 are indifferent.
  • the groove 43, with the opening 44, need not be in the same plane as the orifice 16. This has been shown only for the convenience of understanding the drawing.
  • the secondary part 51 of the sleeve comprises a bowl 12c attached to the main part by at least one arm 52.
  • the bowl consists of several pieces 53, 53 ′, at least two, advantageously three or four, made up and joining together in the manner of quarters, each held by an arm 52, 52 ′.
  • This part of the socket 5 is molded in the form shown in FIG. 3. It is by inserting the socket into the tube 4 that the arms 52 come together and the quarters 53, 53 ′ are pressed against each other to form the bowl 51 while letting the chamber 12 communicate with the dip tube 3 through the spaces left between the arms 52, 52 ′. It is sufficient, during assembly, to introduce the ball 12a at the right time, before the closure of the bowl 51.
  • the ends of the arms 52, 52 ′ extending beyond the quarters 53, 53 ′ serve as a stop for the tube plunger 3 to allow the passage of the fluid around the bowl 51.
  • the molding of the bowl in one piece, secured to a single arm 52 is possible, but this arrangement does not seem to favor the assembly and mounting operations of the device.
  • Figure 4 clearly shows the three parts of the bowl 51 with each corresponding arm 52.
  • the arms leave between them the passages 15, surrounded by the tubular part 4.
