ABSTRACT:
A paint container has a resiliently depressable lid. Depressing the lid actuates a piston to force paint into a rigid tube and the paint then flows into a connected flexible tube. Backward flow of paint in the tube is inhibited during the upward stroke of the lid so that a pumping action is achieved.
