Abstract: An apparatus for spraying lawn products adapted for use with a fluid supply source and a reservoir includes a housing defining a mixing chamber therein and a reservoir coupled to the housing. A process for use of the apparatus is also disclosed. The housing includes a substantially cylindrically shaped cap portion having discontinuous internal threads forming flats therein, a lip portion, and an open end portion. The reservoir includes a generally cylindrically shaped neck portion having a partial exterior shoulder, external threads thereon, and an end portion. Internal threads of the neck portion of the reservoir interengage the discontinuous internal threads having flats therein of the cap portion. The partial exterior shoulder of the reservoir interengages the open end portion of the cap portion such that the end portion of the neck of the reservoir does not engage the lip portion of the cap portion aspirating of the reservoir and housing.

Abstract: A spray nozzle for spreading soluble and non-soluble substances contained within a canister. An inputted fluid flow is divided into a first partial flow to create a slurry within the canister, and a second partial flow which enters a mixing chamber to, in turn, create a venturi effect drawing into the mixing chamber portions of the slurry. An outlet channel deflector reflects the second partial fluid flow against the bottom surface of a flared nose at an exhaust end of the spray nozzle. A combination of two removable discs provides for conversion between use with soluble and non-soluble particles including grass seed, fertilizer, or the like.
