Whirler Is Cup-like Insert With Tangential Inlets Patents (Class 239/492)
  • Patent number: 4071196
    Abstract: An aerosol valve tip and insert assembly adapted for use on aerosol dispensers. The tip includes a body having interconnecting channels and an integral actuator post defining an annular recess. An insert having arcuate shaped bosses defining radial feed channels and a swirl chamber on the rear face is received in the annular recess and abuts the post. The tip and insert assembly provides a substantially uniform aerosol spray pattern and droplet size for carbon dioxide, fluorocarbon, and other pressurized spray formulations over a broad range of pressures.

  • Patent number: 4018387
    Abstract: Pneumatic nebulizer for uniformly dispersing variable amounts of flowable liquid in a gas to form a stable dispersion having the appearance of a natural fog and consisting essentially of liquid particles having a maximum particle size below about 20 microns diameter and having an average particle size well below about 10 microns diameter suspended in said gas. The liquid is forced at a variable rate into a gas flow, at an angle thereto, through an orifice having a width which is variable under the effect of gradual changes in the force of said gas and/or of said liquid to stress the liquid prior to contact with the propellant gas, and is contacted with the propellant gas as it emerges from the orifice in stressed condition for conversion into a stable dispersion having the appearance of a natural fog.

  • Patent number: 3994442
    Abstract: This invention relates to a valve button structure of the type used with an aerosol container and including a terminal orifice insert mounted within the button in aligned, predetermined relation with a feed post. A plurality of feed passages and at least one central feed channel are disposed in predetermined relation to one another and relative to the feed post so as to concurrently direct fluid product issuing from the aerosol container into a fluid swirl chamber or fluid orienting chamber, through said terminal orifice insert so that the fluid product will exit from the valve body at a relatively high rate and in a predetermined pattern dependent upon the particular product being dispensed from the aerosol container.

  • Patent number: 3990639
    Abstract: An aerosol valve actuator, which can also be used for pump-type fluid product dispensing packages, is made from only two molded parts which are screwed together. By screwing and unscrewing the two parts, sprays ranging from a mist to a solid stream, as well as a positive shut-off, can be obtained.
