ABSTRACT:
The present invention discloses a waste disposal apparatus including a container having a first end and a second end. A tubing cassette for supplying tubing is mounted proximate the first end of the container. A first sealing member and a second sealing member are moveable between an open position, wherein tubing from the tubing cassette can pass between the first and second sealing members, and a closed position, wherein the first and second sealing members can be activated to create a seal in the tubing. The first and second sealing members are guided by guide pins that travel along stepped channels for moving the first and second sealing members between the open and closed positions, and for pulling the tubing and waste packages through the waste disposal apparatus.
