  • Publication number: 20040016825
    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.

  • Publication number: 20030209568
    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to a spout connectable to the spray gun and the diaphragm deflects to reduce the volume of the chamber as liquid is withdrawn from the reservoir. The diaphragm gradually conforms to the internal surface of the body as the liquid is withdrawn to prevent pockets forming in which the liquid may be trapped so that substantially all the liquid can be dispensed.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.

  • Patent number: 6596376
    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.
