Abstract
The present invention is a pocket cuspidor which is simple, sanitary and convenient for containerizing oral secretions. Tobacco juice, spitum and other oral secretions are expectorated through a mouthpiece into a small portable container. Pressing a thumb tab simultaneously opens a mouthpiece valve and a vent valve, allowing spitum to enter the container and air, displaced by spitum, to escape. Releasing the thumb tab closes both valves, sealing the container. The small sealed container may be carried conveniently in clothing and handbags. The apparatus includes a container and removable top.
