ABSTRACT:
Pouring devices for accurate blending of color tinters to a base paint are known, but are generally of metal construction including a spout covered by a movable cover plate, with accurate pouring being due mainly to the rigidity of the metal components providing a sharp flow cut-off upon closure of the plate. The invention provides an accurate pouring device including essentially two plastics components in which a sharp flow cut-off can be achieved irrespective of the natural resilience normally present in plastic material. The two components are a cover plate (3) with an integral operating lever (4), and a spout (10) integral with a support body (1). The support body base (5) is elongate and when fitted to a liquid container engages an extended area of the container wall (19) to provide a stable support and to absorb loads applied to the device during use. Connection means are provided for detachably connecting the device over an aperture (20) in the container, including a circular recess (6) in the support body. The recess has a screw thread (7) for engaging a threaded boss (25) upstanding around the aperture. The boss may be an integral part of the container, or a separate collar (21) snap fitted into the aperture.
