CONFORMABLE POUCH RESERVOIR FOR SPRAY GUN

摘要

A reservoir 51 for use with a spray gun has a body 52 and a flexible diaphragm 53 that define a chamber 54 for liquid 57 to be supplied to the spray gun. The body 52 has an outlet opening 55 leading to a spout 56 connectable to the spray gun and the diaphragm 53 deflects to reduce the volume of the chamber 54 as liquid 57 is withdrawn from the reservoir 51. The diaphragm 53 gradually conforms to the internal surface of the body 52 as the liquid 57 is withdrawn to prevent pockets forming in which the liquid 57 may be trapped so that substantially all the liquid 57 can be dispensed. The reservoir 51 may be supplied pre-filled with the liquid 57.
