1,148,147. Valves. ZOLATONE PROCESS Inc. 27 Nov., 1967, No. 53791/67. Heading F2V. [Also in Divisions C3, C4 and F1] The valve of a pressurized container comprises a resilient washer K positioned within a boss G, and which slidably and sealingly engages a rigid tube L that has one or more slots M extending upwardly therein from the bottom. A resilient plug N is affixed to, and closes the lower end of tube L, but does not close the upper portions of slots M. A compressed helical spring S at all times tends to move plug N upwardly and maintain its upper surface in pressure-sealing contact with the lower surface of washer K. Tube L is provided with an actuating handle O having a passage P therein. The container may contain a dispersion type multicolour paint based on methyl cellulose and synthetic resins as film-formers (see Division C3). |
