Abstract

A waste storage device is provided including a waste storage cassette receiving chamber for receiving a cassette rotatable within the chamber and containing tubing for enveloping waste. The device further includes a waste inlet and a throat area therebetween, wherein a releasable gripping assembly is provided in the throat area and arranged for actuation between a released configuration defining an aperture for passage of waste therethrough and a gripping configuration defining a restriction in the throat area.

Claims

1. A waste package storage device comprising a storage space closable at each of an inlet and outlet end and arranged such that when the inlet end is open for receiving a waste package, the outlet end is closed, further including an actuator operable when the inlet end is closed to actuate opening of the outlet end.

2. A device as claimed in claim 1 comprising a further storage space at the outlet end.

3. A device as claimed in claim 1 in which the actuator is one of manually or automatically operable.

4. A device as claimed in claim 3 further comprising a constrictor operable between a non constriction and a constriction position to create a constriction in the storage space upon operation of the actuator.

5. A device as claimed in claim 1 in which the actuator comprises an actuator lever.

6. A device as claimed in claim 5 in which the actuator level comprises an L-shaped foot operated lever.

7. A device as claimed in claim 5 comprising first and second closure embers relatively moveable between an open, spaced position and a closed, abutting position by operation of the actuator.

8. A device as claimed in claim 7 in which the actuator is spring loaded to revert to the open, spaced position.

9. A device as claimed in claim 7 in which at least one closure member is moveable relative to the other.

10. A device as claimed in claim 9 in which one of the closure members comprises a fixed formation.

11. A waste package storage device comprising an inlet and an outlet closure mechanism at respective inlet and outlet ends of a storage space, each closure mechanism comprising first and second closure members relatively moveable between an open, spaced position and a closed, abutting position and an actuator operable to simultaneously move the first and second closure members at the inlet end to an open position and the first and second closure members of the outlet end to a closed position, and vice versa.

12. A device as claimed in claim 11 in which the closure mechanisms are arranged to close waste storage tubing.

13. A device as claimed in claim 11 comprising a further storage space for receiving waste packages from the outlet end.

14. A device as claimed in claim 11 in which at least one of the closure members is moveable relative to the other.

15. A device as claimed in claim 11 in which one of the closure members is fixed.

16. A device as claimed in claim 15 in which the fixed closure member comprises a formation on a waste package storage device housing.

17. A device as claimed in claim 11 in which, in an intermediate position, both of the inlet and outlet closure mechanisms are in an open or partially open configuration.

18. A device as claimed in claim 11 in which the first and second closure members are biased towards the closed position.

19. A device as claimed in claim 11 further comprising a dosing formation for drawing waste package storage tubing from a waste package storage tubing cassette.

20. A device as claimed in claim 11 in which the actuator comprises a lever.

21. A device as claimed in claim 20 in which the inlet and outlet closure mechanisms are biased to a closed position and operation of the actuator overcomes the bias in relation to one of the inlet and outlet closure mechanisms and allows the other of the inlet and outlet closure mechanisms to be biased closed.

22. A device as claimed in claim 11 further comprising a device inlet rotatable about the storage space between an inlet open position in which the first and second closure members of the inlet and are in the open position and an inlet closed position in which the first and second members of the inlet end are in the closed position.

23. A device as claimed in claim 22 in which, in use, the inlet is tilted relative to the vertical above the storage space in at least one of the open and closed position.
