ABSTRACT:
A reservoir for use with a spray gun has a body and a flexible diaphragm that define a chamber for liquid to be supplied to the spray gun. The body has an outlet opening leading to a spout connectable to the spray gun and the diaphragm deflects to reduce the volume of the chamber as liquid is withdrawn from the reservoir. The diaphragm gradually conforms to the internal surface of the body as the liquid is withdrawn to prevent pockets forming in which the liquid may be trapped so that substantially all the liquid can be dispensed. The reservoir may be supplied pre-filled with the liquid.
