Waste disposal device adapted to receive a waste-containing member includes a container defining a waste-receiving compartment having an opening, a lid connected to the container and having a first, closed position covering the opening of the container and a second, open position in which the opening is exposed, and a rotation mechanism arranged in the container to rotate the waste-containing member when present in the container. The rotation mechanism is arranged to rotate the waste-containing member upon closure of the lid. A switch mechanism enables opening movement of the lid to cause the rotation mechanism to rotate the waste-containing member or prevent the rotation mechanism from rotating the waste-containing member depending on a setting of the switch mechanism.

1. A waste disposal device adapted to receive a waste-containing member, comprising: a container defining a waste-receiving compartment having an opening;a lid connected to said container, said lid having a first, closed position covering said opening of said container and a second, open position in which said opening is exposed;a rotation mechanism arranged in said container to rotate the waste-containing member when present in said container, said rotation mechanism being arranged to rotate the waste-containing member upon closure of said lid; anda switch mechanism that is set to one of two different positions to regulate rotation of the waste-containing members based on opening movement of said lid such that when said switch mechanism is in one position, the opening movement of said lid causes said rotation mechanism to rotate the waste-containing member and when said switch mechanism is in the other position, the opening movement of said lid does not cause said rotation mechanism to rotate the waste-containing member. 2. The device of claim 1, wherein said switch mechanism includes a knob accessible from an exterior of said container and a lever mechanism controlled by said knob. 3. The device of claim 2, wherein said rotation mechanism includes at least one gear, said lever mechanism includes a lever mechanism shaft and at least one locking member fixed thereto, each of said at least one locking member including a slot designed to receive a gear shaft about which said at least one gear rotates and retain said gear shaft to thereby prevent radial movement of said gear shaft and thus said at least one gear. 4. The device of claim 3, wherein said rotation mechanism further comprises a rack gear attached to said lid, said at least one gear being motively interposed between said rack gear and a gear rim on the waste-containing member such that when said gear shaft of said at least one gear is retained by said at least one locking member, motive force is transferred from said rack gear to the gear rim and when said gear shaft of said at least on gear is not retained by said at least one locking member, motive force is not transferred from said rack gear to the gear rim. 5. The device of claim 3, wherein said at least one locking member consists of a single locking member arranged at an end of said lever mechanism shaft opposite an end of said lever mechanism shaft attached to said knob. 6. The device of claim 3, wherein said at least one locking member consists of two locking members arranged on opposite sides of said at least one gear. 7. The device of claim 1, wherein said switch mechanism comprises a slide lock with a single engagement on one side of a gear shaft about which said at least one gear rotates to thereby retain said gear shaft and prevent radial movement of said gear shaft and thus radial movement of said at least one gear. 8. The device of claim 1, wherein said switch mechanism comprises a slide lock with a double engagement on two parts of a gear shaft about which said at least one gear rotates to thereby retain said gear shaft and prevent radial movement of said gear shaft and thus radial movement of said at least one gear. 9. The device of claim 1, wherein said switch mechanism comprises a manually accessible and movable slide and at least one trapping portion that is moved upon movement of said slide in one direction to cause said at least one trapping portion to trap a gear shaft about which said at least one gear rotates and moved upon movement of said slide in an opposite direction to cause said at least one trapping portion to move away from said gear shaft and thereby allow radial movement of said gear shaft. 10. The device of claim 1, wherein said rotation mechanism comprises: at least one rack gear coupled to said lid;a gear assembly having a first gear in meshing engagement with said at least one rack gear, and a second, drive gear in meshing engagement with the waste-containing member and which is rotationally coupled to said first gear; anda U-shaped frame pivotally coupled to the lid at an upper end region thereof, said at least one rack gear being arranged on an inside surface of a respective leg of said U-shaped frame. 11. The device of claim 1, further comprising a foot pedal assembly which causes both opening of said lid when depressed and closure of said lid when a pressing force on said foot pedal assembly is removed. 12. The device of claim 11, wherein said switch mechanism and said rotation mechanism are arranged alongside a vertically extending side of said container, and said foot pedal assembly is arranged at a different location and at a bottom of said container. 13. The device of claim 1, wherein said rotation mechanism comprises a first member coupled to said lid, and a force transmission mechanism having a second member engaging with said first member coupled to said lid and a third member engaging with the waste-containing member and which is motively coupled to said second member. 14. The device of claim 13, wherein said first member comprises a rack gear, and said second and third members comprise gears rotationally coupled together. 15. The device of claim 1, further comprising a twisting member that retains the waste-containing member, and comprises a membrane, said membrane being substantially circular and including a plurality of slots extending to a common central aperture, whereby a size of said slots and said central aperture is variable depending on a type of waste for which the waste disposal device is being used. 16. The device of claim 1, wherein said container comprises a transparent window that extends along substantially the entire height of said container to enable viewing of an interior of said container and thus whether the waste-containing member in the interior of said container is full or not. 17. The device of claim 16, wherein said container further comprises an access door that opens to enable access to the interior of said container, said window being formed in said access door. 18. The device of claim 1, wherein said switch mechanism comprises a lever mechanism shaft and at least one locking member fixed to said lever mechanism shaft, andsaid rotation mechanism includes at least one gear,each of said at least one locking member including a slot designed to receive a gear shaft about which said at least one gear rotates and retain said gear shaft to thereby prevent radial movement of said gear shaft and thus said at least one gear. 19. The device of claim 18, wherein said rotation mechanism further comprises a rack gear attached to said lid. 20. The device of claim 19, wherein said at least one gear is motively interposed between said rack gear and a gear rim on the waste-containing member such that when said gear shaft of said at least one gear is retained by said at least one locking member, motive force is transferred from said rack gear to the gear rim and when said gear shaft of said at least one gear is not retained by said at least one locking member, motive force is not transferred from said rack gear to the gear rim. 21. The device of claim 18, wherein said at least one locking member consists of a single locking member arranged at an end of said lever mechanism shaft. 22. The device of claim 18, wherein said at least one locking member consists of two locking members arranged on opposite sides of said at least one gear. 23. The device of claim 1, wherein said switch mechanism comprises a knob extending beyond an outer surface of said container to enable manual access thereto. 24. The device of claim 1, wherein said switch mechanism is configured to be pivotable about an axis defined by a shaft to the two different positions.
