Abstract
The handheld spray receptor provides an apparatus which, when used with a supply of a liquid under pressure, dispenses a liquid material in a pattern that is controlled by an inexpensive and disposable actuator. Such actuators are employed as an industry standard part that would be found on any aerosol spray can, and feature small cylindrical actuators that may be easily interchanged, so as to provide varied spray patterns. A purging model provides for a quick and convenient method of purging liquid from the actuator, so as to prevent hardening of liquid material exposed to the atmosphere, and a subsequent clogging of the receptor. When used with a supply of liquid under pressure and access to a propellant, the handheld spray receptor significantly reduces the amount of hazardous waste, in the form of partially consumed aerosol cans, that would otherwise enter landfills or hazardous waste recycling facilities.
