  • ABSTRACT Regulators and adaptors for pressurized dispensing containers which permit the discharge of product in any position of the container and in a plurality of different discharge characteristics.

  • insects encountered about the home or the like and their habitat pose many difficult and sometimes opposing packaging and dispensing requirements in the use of insecticides.
  • Some types of insects are best controlled by applying the insecticide to surfaces in the vicinity of the insects habitat or in other places where insects alight or congregate.
  • This type of insect control relies in the main on the penetrating vapors and residual action of the insecticide; and thus, in order to obtain optimum insect control, the surfaces must be substantially wetted with the insecticide.
  • the infested'areas usually near baseboards and floors, are wetted with the insecticide.
  • a spray device such as an aerosol dispenser, having a relatively coarse or wet spray discharge characteristic whereby the insecticide spray remains on the surface to be wetted rather than bounces off, as would be the case if a relatively fine spray discharge characteristic is used.
  • insects such as garden pests and flying insects are best and safely controlled by filling the surrounding air or vicinity where the insects are or will be present with insecticide.
  • the insecticide In order, however, to avoid any harmful effects of the insecticide to persons or things, such as plants, in the vicinity and in order to properly fill the air, the insecticide must be dispensed in a very fine particle size. Typically, this is done by utilizing a spray device, such as an aerosol dispenser, having a fine spray discharge characteristic rather than a wet spray characteristic as is necessary for wetting surfaces.
  • a pressurized dispensing container such as an aerosol, which permits discharge of product, for example insecticide, in any position of the container and in a plurality of different discharge characteristics.
