Abstract:
1. A waste disposal system with flexible tubing comprising: a container defining a waste chamber for receiving waste; a lid connected to the container and movable between an open condition, in which access to the container is provided, and a closed condition, in which the container is covered; an iris comprising a first disk, a second disk and a web, wherein the first disk and the second disk are ring shaped, parallel and coaxial, wherein the web connects the first disk and the second disk, and wherein the iris is structured to rotate from an open position, in which waste can flow through the iris, to a closed position, in which flow of waste through the iris is hindered and wherein said iris is structured to move toward and away from the lid; a cartridge of flexible tubing removably situated in the container, wherein the flexible tubing extends from the cartridge through the iris into the waste chamber and is arranged to receive waste therein; and a guide for guiding and causing the iris to move from the open position to the closed position by generating a relative rotation between the first disk and the second disk, further causing the iris to twist and cinch the flexible tubing and to enclose the held waste, and still further causing the iris to move in a direction opposite to the lid and to carry the held waste into the waste chamber.
