Abstract
A waste storage device includes an inlet aperture and a length of flexible tubing passing through the inlet aperture from a cassette. The flexible tubing is pinched by a pair of rollers which can have continuous surfaces or multiple paddles. The waste product is placed into the aperture and the rollers rotate drawing the waste product down into the device and pinching the storage bag above it. The operation can be manually or motor driven.
