SPARY GUN WITH PRESSURE ASSISTED LIQUID SUPPLY CUP COMPRISING AN INNER LINER

摘要

An assembly (10) for feeding liquid to the inlet port of a liquid spraying device or spray gun (11). The assembly includes a stiff container (12) and a flexible liner (20) positioned within the cavity in the container (12) having an outer surface generally corresponding in shape to the inner surface of the container and an annular lip along the top end of the side wall defining an opening into the cavity of the liner (20). An air supply assembly (90) connected to the container (12) supplies air at a relatively low pressure between the outer surface of the flexible liner (20) and the inner surface of the container (12) which improves the flow of liquids through the liquid spraying device or spray gun to which the assembly is attached, and allows that spraying device or spray gun (11) to be used in any orientation.
