Abstract
Abstract A pouring spout removably mounted on a container, as a paint can, having an upwardly directed circular lip surrounding the open top of the container. The spout is a one piece pliable plastic member having a base with an arcuate groove with a radius of curvature larger than the radius of curvature of the container lip and a sheet chute member attached to the base. The chute member is flexed to a generally U shaped trough configuration when the base is mounted on the lip of the container.
