ABSTRACT:
A liquid spray gun including (1) a reusable air gun portion including a manually operable valve for controlling air flow; and (2) a disposable container and spray nozzle assembly including a sheet of flexible material having portions attached together and to a central portion of a tube to form a chamber, a liquid in the chamber, and an aspirating nozzle connected to the tube and adapted to be releasably coupled to the air gun portion so that upon movement of air through the nozzle liquid in the chamber will be entrained in that air and sprayed from the nozzle. The assembly can include a coil comprising a strip disposed in a plurality of wraps about an axis and having a spring temper biasing the strip to an axially extended position to form a tube like structure, with an end portion of the coil positioned around an end portion of the tube within the bag so that during spraying the tube like structure will insure that most of the liquid can be dispensed from the chamber. The sheet of flexible material also includes edge segments that are not attached together to thereby form vents for communicating the chamber to the atmosphere.
