A waste disposal device comprises a container having a top opening. The container provides access to an inner cavity that receives a bag with opened and closed ends. A pivoting lid closes/opens access to the opening. An actuation mechanism has a user-actuated interface. A linkage connected to the interface opens/closes the lid. A pair of jaws is connected to the linkage. The jaws move between a clamped position, in which the jaws close off a portion of the bag, and an opened position, in which the jaws are separated to allow waste to reach the closed end. The jaws and the lid are actuated concurrently by a single degree of actuation on the interface, allowing the lid to open and close while the jaws move from the clamped to the opened position, and back to the clamped position. A method for disposal of a waste object is also provided.

1. A waste disposal device comprising: a container having an opening at a top end, the container defining an inner cavity accessible through the opening, for receiving a bag opened at the opening of the container and having a closed end in the inner cavity;a lid pivotable to close/open access to the opening; andan actuation mechanism having an interface actuated by a user, the actuation mechanism comprising a linkage connected to the interface to open/close the lid, and a single pair of jaws connected to the linkage to move between a clamped position in which the jaws close off a portion of the bag passing therebetween, and an opened position in which the jaws are separated to allow waste to reach the closed end of the bag under the pair of jaws, the jaws and the lid being concurrently actuated by a single degree of actuation on the interface, by which the lid moves from opened to closed while the jaws move from the clamped position to the opened position and back to the clamped position. 2. The waste disposal device according to claim 1, wherein the interface is a pedal, and the single degree of actuation is a release of pressure on the pedal. 3. The waste disposal device according to claim 1, wherein the linkage has a portion translating in a generally vertical direction in the inner cavity, the linkage having a top pushing end contacting the lid to displace the lid to open access to the opening. 4. The waste disposal device according to claim 3, wherein the jaws are pivotally connected to a structure in the inner cavity of the container, and wherein a set of pins and guide slots is provided between the jaws and the linkage for the jaws to move between the clamped position and the opened position as a function of a translation of the linkage in the generally vertical direction. 5. The waste disposal device according to claim 4, wherein the guide slots each have straight portions with a bent portion therebetween, the jaws moving from the clamped position, to the opened position and back to the clamped position when each of the pins moves sequentially from one of the straight portions, to the bent portion, and to the other one of the straight portions. 6. The waste disposal device according to claim 4, wherein the guide slots each have a straight portion with a blocking unit therein, and a bent portion joined in parallel relation with the straight portion, the jaws moving from the clamped position, to the opened position and back to the clamped position when the pins each move into a corresponding one of the bent portion as a function of the single degree of actuation closing the lid, the jaws remaining in the clamped position when the pins move in the straight portion and by the blocking unit as a function of the single degree of actuation opening the lid, the pin being directed to the bent portion by the blocking unit. 7. The waste disposal device according to claim 6, wherein the blocking unit is a ramp in the straight portion with the pin passing over the ramp when the single degree of actuation opens the lid, the ramp directing the pin to the bent portion when the single degree of actuation closes the lid. 8. The waste disposal device according to claim 4, wherein the pins are integral with the jaws, and the guide slots are in the linkage. 9. The waste disposal device according to claim 4, further comprising a support arm connected to an interior of the container, and pivotally supporting at least one side of the jaws, the support arm being sandwiched between the jaws and the linkage and defining an opening for the operative connection between the pins and guide slots. 10. The waste disposal device according to claim 4, comprising meshing on a periphery of the jaws, whereby the jaws are intermeshed for concurrent rotation between the clamped position and the opened position. 11. The waste disposal device according to claim 4, further comprising a set of pins and seating slots provided between the jaws and the linkage, the pins received in the seating slots when the lid is closed and the jaws are in the clamped position to lock the jaws against one another with the bag passing therebetween. 12. The waste disposal device according to claim 4, further comprising a biasing unit biasing the jaws toward one another. 13. The waste disposal device according to claim 1, further comprising at least one biasing unit biasing the linkage to a downwardmost position to keep the jaws in the clamped position. 14. The waste disposal device according to claim 1, wherein the jaws have a wavy surface at an area of contact therebetween. 15. The waste disposal device according to claim 1, wherein the container comprises a top portion and a base portion, the top portion being pivotally connected to the base portion for access to the inner cavity of the container. 16. The waste disposal device according to claim 15, wherein the linkage comprises a first link member connected to the interface by a joint, and a second link member connected to a free end of the first link member by an other joint, the other joint allowing relative movement of the link members when the top portion is pivoted open with respect to the base portion. 17. A method for the disposal of a waste object in a waste disposal device comprising a container with an opening at a top end closed by a lid, a bag opened at the opening and having a closed end positioned inside the container, jaws closing off a portion of the bag passing therebetween, and a pedal mechanism for opening/closing the lid and actuating at least one of the jaws, the method comprising: opening the lid as a result of a pressure applied on the pedal;receiving a waste object in the bag on top of the jaws;closing the lid as a result of a release of the pressure applied on the pedal;separating the jaws for the waste object to fall under the jaws in the closed end of the bag during the release of the pressure; andbringing the jaws against one another with the bag therebetween and the waste object captive in the closed end of the bag below the jaws during the release of the pressure. 18. The method according to claim 17, wherein opening the lid comprises keeping the jaws against one another continuously while pressure is applied on the pedal. 19. The method according to claim 17, wherein separating the jaws and subsequently bringing the jaws against one another occur once the lid as reached a closed position.
