1. A waste package storage device comprising a lid hingedly connected to the waste storage device, the lid moveable from an open position to a closed position, an inlet closure mechanism positioned below the lid 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 comprising a lever operable to simultaneously rotatably 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; wherein the first and second outlet closure members at the outlet end define a channel for receiving a waste package, and wherein the first and second outlet closure members at the outlet end are rotatable in order to release a received waste package from the outlet end of the waste package storage device, and wherein 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. 2. A device as claimed in claim 1 in which the closure mechanisms are arranged to close waste storage tubing. 3. A device as claimed in claim 1 comprising a further storage space for receiving waste packages from the outlet end. 4. A device as claimed in claim 1 in which at least one of the closure members is moveable relative to the other. 5. A device as claimed in claim 1 in which, in an intermediate position, both of the inlet and outlet closure mechanisms are in an open or partially open configuration. 6. A device as claimed in claim 1 in which the first and second closure members are biased towards the closed position. 7. A device as claimed in claim 1 further comprising a dosing formation for drawing waste package storage tubing from a waste package storage tubing cassette. 8. A waste package storage device comprising a lid hingedly connected to the waste storage device, the lid moveable from an open position to a closed position, an inlet closure mechanism positioned below the lid 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 comprising a lever operable to simultaneously rotatably 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; wherein the first and second outlet closure members at the outlet end define a channel for receiving a waste package, and wherein the first and second outlet closure members at the outlet end are rotatable in order to release a received waste package from the outlet end of the waste package storage device, and wherein 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. 9. A device as claimed in claim 8 wherein the first and second closure members in the inlet closure mechanism are movable between an open spaced position and a closed abutting position by operation of the actuator. 10. A device as claimed in claim 8 wherein the first and second closure members of the outlet closure mechanism are relatively movable between an open spaced position and a closed abutting position by operation of the actuator. 11. A device as claimed in claim 8 wherein the first and second closure members of the outlet closure mechanism each define a channel for receiving a waste package when in an open position. 12. A device as claimed in claim 8 wherein each of said first and second closure members of the outlet mechanism is rotatable in order to move a received waste package towards a storage space below the outlet closure mechanism. 13. A device as claimed in claim 8 further comprising a waste storage cassette housed therein. 14. A waste package storage device comprising a lid hingedly connected to the waste storage device, the lid moveable from an open position to a closed position, an inlet closure mechanism positioned below the lid 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 comprising a lever operable to simultaneously rotatably move the first and second closure members at the outlet end to an open position and the first and second closure members of the inlet end to a closed position; wherein the first and second outlet closure members at the outlet end define a channel for receiving a waste package, and wherein the first and second outlet closure members at the outlet end are rotatable in order to release a received waste package from the outlet end of the waste package storage device, and wherein 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. 15. A device as claimed in claim 14 wherein the first and second closure members in the inlet closure mechanism are movable between an open spaced position and a closed abutting position by operation of the actuator. 16. A device as claimed in claim 14 wherein the first and second closure members of the outlet closure mechanism are relatively movable between an open spaced position and a closed abutting position by operation of the actuator. 17. A device as claimed in claim 14 wherein the first and second closure members of the outlet closure mechanism each define a channel for receiving a waste package when in an open position. 18. A device as claimed in claim 14 wherein each of said first and second closure members of the outlet mechanism is rotatable in order to move a received waste package towards a storage space below the outlet closure mechanism. 19. A device as claimed in claim 14 further comprising a waste storage cassette housed therein.
