Abstract: An injection assembly for an injection molding machine in which an auger is disposed in a bore formed in the molding machine and defines therewith an annular passage for receiving the material to be injected. A valve assembly is operatively connected to the auger and includes internal passages communicating with the annular passage and adapted to communicate with the mold. A sealing ring extends around the valve with the outer diameter of the sealing ring being in a sealing relation to the bore downstream of the annular passage. The inner diameter of the ring is slightly greater than the outer diameter of the valve to permit rotation of the valve relative to the sealing ring. As a result, upon rotation of the auger and the valve, the material is advanced along the annular passage and the internal passages while the sealing ring remains stationary and provides the sealing function.

Abstract: A lid for a plastic trash can having interlocking structures therewith at diametrically opposite sides thereof, each said structure including an inverted rim on both lid and can, a handle spaced from the container but integral therewith, and a pair of spaced vertical walls for each handle, a slot in each wall, the rim of the lid being lodged in the slots with the lid in place to close the container.
