Abstract
An air-suction nozzle for greatly improving the efficiency of waste disposal by compacting trash-filled bags. The air-suction nozzle has a hub member having an opening to communicate with an air-suction line, an outer tube air-tightly held by the hub member and having perforations, an inner tube held by the hub member concentrically with the outer tube and having at least one perforation at a position close to the hub member and communicating with the opening in the hub member, and a plug member sealing and holding the outer and inner tubes concentric at the respective ends remote from the hub member. The air inside a trash-filled plastic bag can be sucked out through the nozzle inserted into the bag without sucking of water even when the trash is wet.
