Abstract: A spray gun has a fluid reservoir that contains a removable liner. The liner, which may be thermo/vacuum-formed from a plastics material, is a close fit within the interior of the reservoir and collapses as fluid is withdrawn from within the liner during operation of the gun. Preferably, the liner has a comparatively-rigid base and is capable of standing, unsupported, outside the reservoir. The side walls of the liner are preferably thin in comparison to the base and can be collapsed for disposal of the liner. The reservoir has a removable lid and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid also functions to secure the liner in the reservoir and, at the end of a spraying operation, the lid and the liner are removed together from the reservoir and discarded, thereby simplifying the cleaning of the spray gun.

Abstract: A masking material (28) comprising an elongate strip (8, 30) at least partially coated with a layer of a pressure-sensitive adhesive (4, 22), the strip having a curved surface which is convex when the strip is viewed in cross-section and is positioned such that when the strip is adhered to a substrate by the layer of pressure-sensitive adhesive a portion of the curved surface overhangs the substrate, characterized in that the masking material comprises a removable edge portion (10, 32) comprising said portion of the curved surface detachably secured to a remainder of the strip which may be removed to expose a second curved surface on the remainder of the strip which is convex when viewed in cross-section and which is positioned to overhang the substrate, said removable portion (10, 32) and remainder of the strip (8, 30) having different dimensions.

Abstract: A spray gun and a detachable liquid reservoir releasably attached to the spray gun by engagement of mateable, non-threaded formations provided on the spray gun and the reservoir. The spray gun has an integral connector boss with a socket for reception of a connector tube of the reservoir. The boss has an external flange at the distal end and the reservoir has hook members separate from the connector tube. The hook members are co-operable with the flange when the connector tube is received in the socket to secure releasably the reservoir to the spray gun. In another arrangement, the connector tube is an interference friction-fit in the socket to secure releasably the reservoir to the spray gun. In yet another arrangement, the connector tube has bayonet lugs co-operable with bayonet grooves in the wall of the socket when the connector tube is received in the socket to secure releasably the reservoir to the spray gun.

Abstract: An assembly for feeding liquid to the inlet port of a gravity feed sprayer. The assembly includes (1) a mixing cup of a known type commonly used to mix paint with solvent that is of stiff polymeric material and bears indicia on its side wall indicating the levels to which a plurality of different liquids should be sequentially poured into the cup to achieve a predetermined ratio between the liquids; (2) a first adapter comprising a central portion having a through opening and a transverse portion including a peripheral part defining a groove along its inner surface adapted for sealing engagement with a top end of the mixing cup; and (3) a second adapter having a through opening, a first end portion of which second adapter is adapted to releasably engage the inlet port of a gravity feed paint sprayer.

Abstract: A masking material comprises an elongate strip at least partially coated with a layer of a pressure-sensitive adhesive, die strip having a curved surface which is convex when the strip is viewed in cross-section and is positioned such that when the strip is adhered to a substrate by the layer of pressure-sensitive adhesive a portion of the curved surface overhangs the substrate. The masking material comprises a removable edge portion comprising said portion of the curved surface detachably secured to a remainder of the strip and which may be removed to expose a second curved surface on the remainder of the strip which is convex when viewed in cross-section and which is positioned to overhang the substrate. The removable portion and remainder of the strip have different dimensions. Methods for making such masking material are also described.
