Abstract
Abstract A sponge disposal tray for use in conjunction with medical surgical procedures which comprises a plurality of containers which are normally closed by a thin sheet material access cover. The access cover includes a plurality of access openings with a single access opening connecting with a single container. Each access opening comprises a pair of crossed slits which is normally closed but openable upon insertion of a single sponge into a container. A removable sealing cover is to be adhesively secured to the frame and to completely cover said access cover. The frame may include a sponge storage compartment. Also the bottom surface of each of the containers may include an adhesive layer to facilitate frictional connection of the tray to a supportive surface.
