Abstract
A spray gun reservoir has an oversize central opening 130 at one end allowing liquid to be added to the reservoir for fast filling with reduced risk of spillage. A cap member 132 is connectable to the reservoir and has a spout 115 providing a fluid outlet of reduced size relative to the opening 130 for connection to the spray gun. The reservoir can be disconnected from the cap member 132 when it is desired to add liquid to the reservoir. In this way, the reservoir can be re-filled in use.
