Definitions

  • This invention relates to dispensing apparatus for use in connection with the distribution or dis- It is more specifically addressed to the provision of a lowcost valve for the formation of aerosols from liquids under ⁇ superatmospheric pressure. While ,our new valve is particularly suited to the application of insecticides, fumigants, hormones or the like, it is also adapted to the dispensing of other substances where dispersion in extremely small particles is desired, such as coatings, medicinals, nasal sprays, and the like.
  • a method suggested for effecting such a dispersion is to maintain a solution of the active agent or agents in a liquefied gas confined under high pressure in a'container and to release it into the atmosphere through an orifice, thereby obtaining rapid evaporation of the solvent and dispersion of the solution into small particles.
  • the advantages to be derived from extremely small particle size are such that they cannot be achieved to the fullest extent by using previously known devices for dispersing them.
  • the problems involved in the formation of the desired small particles, and especially of aerosols are increased when the dispersion is to be effected from a liquid maintained at a relatively low degree of superatmospheric pressure-for example, in the neighborhood of50 lbs. per square inch (gauge) or lower.
  • An object of this invention is an improved valve device for dispensing or dispersing insecticides, or
  • a further object is to provide such a device in a form which can be inexpensively and readily manufactured, and isl easily manipulated to dispense any desired part of the contents of the container to which it is affixed, at other times serving as a seal to prevent leakage and loss.
  • the device is suitable for permanent attachment to a container holding under pressure the uid to be dispensed, so that the charcoal and chamber sizes can be fixed by the manufacturer to correspond with the properties of the fluid and the particle size required, so as to assure uniformity of operation throughout the charge, with no adjustments to be made by the user.
  • Fig. 1 is a sectional view of one form of our valve device showing a preferred method of mounting it on a container;
  • Fig. 2 is the same device as shown in Fig. 1, but with the valve unseated, in the position it takes when the contents of the container are being dispersed;

  • the assembly constitutes a valve, shoulder 2Ia functioning as the valve member and the ring I9 as the valve seat.
  • the valve may be unseated either by inward movement of eyelet 23, which may be brought about by pressing it inwardly against the reaction of spring I8, thereby wholly disengaging the shoulder 2Ia from the sealing ring I9, or by tilting eyelet 23 by radially applied pressure, thereby rotating it about point A and disengaging the rim from the ring in that region of the seat toward which the eyelet is tilted, as shown at X in Fig. 2.
