Definitions

  • the present invention relates to a vaporizer pusher. It adapts to the stem of the valve, preferably a metering valve which, when at rest, closes the container from certain vaporizers and allows, by simple pressure of the finger, to push it back slightly so that the product contained in the container escapes ( hereinafter called the main product).
  • the pusher of the invention has the particularity of mixing a predetermined amount of another product (called below secondary product) and this , while the main product is being released. So we baptized this pusher "exomix”.
  • drugs to be vaporized consist of a basic product, possibly a solvent, and an additive, possibly a solute, for example two liquids or a liquid and a powder, which cannot not be contacted well in advance. Its use is also part of the present invention.
  • a pusher capable of carrying out such a mixing is in particular known in the prior art.
  • This is described in French patent FR-A-1 506 698 filed in 1966 by MARRAFFINO. It comprises a hollow cylinder terminated by a spout which, at the same time, serves as an emission channel and as an actuating member of the valve of the vaporizer.
  • the user releases for example his shaving foam which heats up by entraining and mixing with the water of the emission channel.
  • This series of chambers is arranged in a first room forming the pusher of the invention.
  • This first part is movable relative to a second part of said pusher containing the transmission channel.
  • the section of Figure 1 shows a support 1 surmounted by its barrel 2, according to a possible embodiment of the invention.
  • the axis of these cylindrical parts is arranged vertically.
  • the shape of the lower part of the support is adapted to the valve body of certain vaporizers.
  • the hollow stem of their valve (preferably of the metering type) then fits into the support 10. Its depth as well as the height of the lower crown 17 are calculated as a function of the stroke of the valve stem when the latter opens and closes.
  • the support 10 communicates with a transmission channel 11 which is arranged along a radius normal to the axis of the support 1. It opens at the periphery of the support 1 on a lateral emission orifice 13 which here corresponds to an enlargement of section. As shown in the variant form of FIG. 2, this arrangement is not systematic.
  • the orifice 13 can also admit a section identical to that of the channel 11, or even smaller.
  • a nozzle nozzle may possibly adapt to it.
  • cylindrical reserves 14 are provided on the upper part of the support 1. Their respective axes, also vertical, are equidistant from the axis of the support 1. The reserves are also regularly arranged on the circle thus defined, so that, for a given section, their number depends on the radius of this circle.
  • Figure 3 shows how they could be placed in a horizontal plane. Three possible configurations are shown: eight reserves on the inner circle, twelve on the intermediate circle and twenty-four on the outer circle.
  • the axis of one of the reserves intersects that of the transmission channel 11.
  • the corresponding reserve is deep enough to communicate with the channel.
  • a punch 12 is however embedded in the bottom of this reserve so that its point is located above the transmission channel. The passage of a liquid or a powder from the reserve to the channel is then ensured by means of several vertical slots made in the punch.
  • the horizontal section of Figure 4 specifies an embodiment of the intersection of channel 11 and the reserve.
  • a cylinder 15, of the same axis as the support 1, projects from the upper surface of said support. It ends with a cone with shoulder which gives it the appearance of a mushroom. As shown in Figure 2, it can be composed of two flexible plastic tabs which move horizontally from each other as soon as they are no longer pressed together. Thus, the cylinder 15 is able to snap into an opening of section smaller than that of its shoulder and having bevelled edges without any subsequent separation being possible. This property is used to irreversibly mount the barrel 2 on the support 1 by engaging the cylinder 15 in the cylindrical guide 25 of the barrel 2. It is clear that the same result would be obtained if the cylinder 15 was fixed to the barrel 2 and if the guide 25 belonged to the support 1. In addition to its role of connection between support and barrel, the cylinder 15 also allows the rotation of one part relative to the other about their vertical axis which is therefore common. This is why it is called below rotation shaft 15.
  • the upper face of the barrel 2 is flat, its lower face comprises, in addition to the cylindrical guide 25, several reservoir cylinders 21 with a vertical axis.
  • Their common section is slightly less than that of the reserves of the support 1 so that they can slide there without excessive friction while ensuring good sealing of the cylinder / reserve interface.
  • Their number and arrangement around the axis of barrel 2 is generally identical to the number and arrangement of reserves around the axis of the support 1. It is however possible in this configuration, that one or more reservoir cylinders are missing.
  • the reservoir cylinders are more or less hollowed out depending on the quantity of secondary product that the lower chamber 22 must contain.
  • Their base is closed by a slightly resistant cover 23. It is for example a plastic film welded to the wall of the reservoir cylinders 21.
  • the supports 1 and the barrels 2 of the present invention will preferably be molded each in one piece. Partitions 18 and 26 may remain on these parts, dividing their lower surface into parts of cake while reservoir-cylinders 21 and reserves 14 are halfway between the partitions.
  • the punch 12 is indifferently molded with the support 1 or else placed on the latter thereafter. In the latter case, a harder plastic material can be used.
  • a device can be provided so that only a full reservoir-cylinder is present opposite the punch during the emission and that any emission of main product becomes impossible after the emptying of all tank cylinders.
  • a notch disposed on the outer ring 24 of the barrel 2 is for example capable of circulating, in one direction only, on a rack fixed to the upper ring 16 of the support 1 and comprising a stop. The passage from the notch from a notch of the rack to the next would be done for example when the force F is released and the spring decompresses.
  • the pusher of the invention can also be advantageously mounted on a vaporizer containing an inert gas under pressure such as nitrogen, CO2 or freon .
  • an inert gas under pressure such as nitrogen, CO2 or freon .
  • the released gas makes it possible in this case to strongly entrain the liquid or the powder of the chamber 22. It is a way of obtaining the finely divided emission (particles of diameter of the order micron) which is necessary for the application of certain drugs such as those used to calm irritation of the bronchi.
