ABSTRACT:
A plunger-type paint roller cleaning device wherein such device is suitably constructed for forcing a solvent longitudinally and peripherally through the nap of a wet, previously-used paint roller. In one embodiment a one-way valve is employed in conjunction with a container suitably designed to receive a paint roller. The plunger of the invention serves to draw external solvent fluid inwardly within the container, whereas a reverse action of the plunger forces the charge of solvent so drawn in to proceed longitudinally and peripherally through the roller nap, such solvent thereby carrying wet paint or other painting medium from the nap for exit from the container. In another embodiment the container receives the roller and then is filled with a charge of solvent, the container later to be closed. The plunger employed swishes the solvent back and forth longitudinally and peripherally through the nap of a roller to be cleaned; subsequently, a portion of the container of the device is removed so that the charge of now paint-laden solvent can be removed. Open-ended cylinders are or may be used for constricting the space between the nap of the roller and exterior structure and also for supplying a smooth cylinder wall for the piston of the plunger.
