Abstract: The present invention provides for a dispensing apparatus which will successfully disperse a minute amount of fertilizer during each watering of gardens, lawns, or the like. The apparatus of the present invention includes an inner chamber which is housed within an outer chamber. The inner chamber maintains a water soluble fertilizer and also includes an inlet and an outlet. An inlet and outlet is also at the outer ends of the outer chamber. A gap or space is situated between the inner chamber and outer chamber. For utilizing the device of the present invention, the user attaches a conventional water source to the inlet of the outer chamber while a water discharge device is secured to the outlet of the device. Water enters the inlet of the outer chamber and flows into the space or gap as well as enters the inner chamber via the inlet. The water within the inner chamber causes the fertilizer to dissolve and form a solution. This solution exits the inner chamber via the outlet.

Abstract: The shower spa fixture is mounted between an inlet pipe and a shower head and includes a container for mixing a stream of water with additives. A portion of the stream of water passing from the inlet pipe to the shower head is diverted into the container. The container includes a replaceable cartridge which has a first additive in a first chamber and a second additive in a second chamber. The diverted stream of water mixes with the first additive in the first chamber, passes through a screen to the second chamber, and mixes with the second additive in the second chamber. The diverted stream containing additives is then returned to the main stream of water which exits the shower head. The amount of additives added to the main stream of water is controlled by a control valve. The present invention provides an improvement over known arrangements by providing two additives which are kept separate from one another preventing a chemical reaction between the additives which would cause a loss of potency.

Abstract: A method and apparatus for metering and dispensing an active ingredient, such as an insecticide, fumigant, fertilizer or room freshener. The active ingredient is placed in a container 6 and a pressurized propellant is subsequently introduced from a source 1 via conduits 3, 9. The propellant serves to absorb the active ingredient which is dispersed from the container via conduit 5 through a dispensing outlet 8 so that the active ingredient is dispersed in an airborne dispersion. In an ejector 4, a pressure differential is created across a propellant inlet port 4a which is sufficient to draw the active ingredient from the active ingredient container 6 but is less than the pressure differential required to cause a cooling effect in the mixing chamber 4 and is less than that pressure differential that gives rise to an erratic dispersion of the active ingredient from the dispensing outlet 8. The system is particularly suitable for the spraying of insecticides into large spaces such as warehouses and supermarkets.
