Abstract: An apparatus for dispersing an active ingredient, such as a fumigant, fertilizer or room freshener in which the active ingredient is placed in a sample cylinder and a pressurized solvent/propellent is subsequently introduced from a source. The solvent/propellent expands to adopt a liquid phase and a gaseous phase. The liquid phase serves to absorb the active ingredient and the gaseous phase serves to propel the borne active ingredient out of the apparatus through a dispensing outlet where further expansion takes place and the active ingredient is dispersed in a fog or mist. Flow restrictors create a pressure differential between the sample cylinder outlet and a by-pass portion to enable total absorption of the active ingredient. The flow restrictors and conduits for the system are contained in a mixing head for the sample cylinder.

Abstract: An ampoule holder comprises a body part 1 and a head part 2 which are connected together by a pair of hinge strips 3 and a breakage link 4. A glass ampoule 7 is inserted, stem first, through an opening 6 in the base of the body portion 1. The body of the ampoule is forced past inwardly extending projections 8 until the lower end of the ampoule snaps past these projections and the shoulder at the top of the body of the ampoule 7 abuts against the curved hinge parts 3. The base of the ampoule will then be raised above the projections 8. The stem 10 of the ampoule is gripped within the head portion 2 of the holder by internal ribs or spines 11, so that the neck 9 of the ampoule is aligned with the breakage link 4.
