ABSTRACT:
A container for liquid is disclosed, wherein the container has an improved self draining means featuring a radially inclined ramp which slopes downward from the container pouring spout in the radially outward direction. Beneath the drain ramp is an annular channel which receives liquids gravity draining from any azimuthal location on the ramp, and routes the liquids to a drain hole, returning the liquids to the container reservoir. One or more projections may be disposed within the annular channel to partially block it. This arrangement prevents any plastic shavings or other debris within the channel from migrating or being washed by the draining liquid to a location visible to the user or to the drain hole where such debris may contaminate the contents of the container.
