Title:
WASTE DISPOSAL DEVICES
Document Type and Number:
WIPO Patent Application WO2002087795
Kind Code:
A3
Abstract:
Waste disposal device including a container (12) with a waste storage chamber (12a) and a cartridge (24) therein with contains a length of flexible tubing (34) for encapsulating waste packages (74). A retention mechanism (72) holds the waste package. A rotation mechanism causes relative rotation between the cartridge and the retention mechanism to form a twist above the waste package, thereby encapsulating the waste package in the tubing. Encapsulation of the waste package prevents the release of odors and provides a convenient and sanitary disposal of the waste. A series of encapsulated waste packages is created in the container, each package contained within a portion of tubing and sealed at each end by the twisting process. Once encapsulated, the waste package is urged further into the container upon subsequent insertion of another waste package or by a compacting mechanism (248) which rolls the encapsulated waste packages into a compacted roll.
