Definitions

  • the present invention relates to a device for allowing the operation in any position of a vaporizer valve.
  • French Patent No. 1,463,819 describes a fairly simple device, but the operation of which is not satisfactory. In the upright position, it operates normally. But, in the inverted position, although it is said in this patent "there will be no losses of the propellant ", in fact, the losses are significant, the operation is defective, and the we may not be able to extract all of the product from the container.
  • the Applicant has sought to solve this problem, made hypotheses, then tests, and has managed to find that the functioning of devices of the kind in question can be decisively improved if certain dimensional ratios are taken into account.
  • the present invention therefore relates to a device for allowing the operation in any position of a vaporizer valve, adapted to be mounted in the opening of the neck of a container, and comprising inside the container a inlet conduit into the valve of the product to be vaporized, into which conduit opens, on the one hand, through a first orifice, a dip tube extending to the vicinity of the bottom of the container, opposite the neck, and on the other hand share, by a second orifice, a bypass opening into the upper part of the can, in the vicinity of the neck, said bypass comprising a valve closing the bypass when the can is in an upright position, the section of the second orifice being substantially larger than that of the first port.
  • the ratio of the sections of the second orifice to the first is between 1.5 and 4.
  • the two orifices are coaxial, with the axis of the valve, the bypass including a cylindrical chamber of the same axis, the valve being constituted by a ball housed with play in said chamber, and resting when the container is in an upright position, on a seat surrounding said second orifice, the inlet conduit in the valve bypassing said chamber, from one end to the other.
  • the valve shown in the figures comprises a valve body 1 intended to be mounted in the opening of the neck of a container (not shown) by a capsule 2.
  • a valve stem 3 emerges from the capsule, and from the container. Inside the container, the valve body ends in a nozzle 4 intended to receive a dip tube, in a conventional manner.
  • the valve has a chamber 5 which is filled with a liquid contained in the container, under the thrust of a propellant.
  • the valve can be of any type.
  • the valve stem is biased outwards, upwards, as a result of the deformation of flexible tabs 6 against a conical wall 7 limiting the volume of the chamber downwards.
  • the valve stem has a groove 8 in which engages a seal 9 wedged between the valve body and the capsule. By pushing the rod 3, the bottom of the groove is released, and discovers an orifice 10 putting the groove in communication with a blind axial channel 11 through which the liquid contained in the container can escape.
  • the valve chamber is filled through the conduit 12.
  • a bypass 17 provided with a valve 18, closed when the valve is in the straight position.
  • This bypass communicates with an opening 19, opening in the region of the upper part of the valve, that is to say in the region of the upper part of the container.
  • the valve is, in this example, constituted by a ball 18 resting on a seat 20 surrounding the orifice 16. In the normal upright position, the valve is therefore closed. If the valve is turned over, or lying down, the valve is open.
  • the two orifices 15 and 16 open out separately in the conduit 12 for filling the valve chamber, if necessary directly in the chamber, and the orifice 16 has a section substantially greater than that of the orifice 15 through which the dip tube opens.
  • the orifice 16 In the straight position, the orifice 16 is closed, and the valve operates as if the bypass did not exist.
  • the pressure of the propellant gas in the bypass 17 tends to apply the ball to its seat and keeps the valve closed, due to the vacuum prevailing in the conduit 12 when the valve is open (valve depressed).
  • the ratio of the sections, that of the orifice 16 of the branch 17 to that of the orifice 15 of the dip tube, can advantageously be of the order of 2, more generally between 1.5 and 4.
  • the branch 17, with the valve 18 can be placed axially, in the axis of the valve, and the two orifices 15, 16 can be placed opposite one of the other, coaxially.
  • the inlet conduit 12 in the valve laterally bypasses the bypass 17, which forms a second axial chamber, by a lateral passage 12 b.
  • the bypass chamber 17 can be delimited by a molded part 21 forming on one side the wall 7 conical delimiting the valve chamber 5.
  • the valve seat 20 is engaged in the molded part 21 and rests against a suitable shoulder 22.
  • the seat 20 and the molding 21 are provided with respectively 20 feet and 21 is to allow the wedging through the bottom of the valve body 1, leaving the conduit 12 a clear .
  • the assembly of the assembly does not require any orientation of the various component parts.
  • the valve can be mounted on bottles with an opening of less than 20 mm.
  • valve body In the bottom of the valve body, place the valve seat 20, then the ball 18, then the molded part 21, then the valve 3 with the seal 9, and the assembly is crimped with the capsule 2 until that it is itself crimped on the neck of a can, filled with a liquid to be atomized. After which, the propellant is introduced in a conventional manner.
