Waste bin liners, such as rigid liners, methods of using waste bin liners, and combinations of waste bins with a liner, are disclosed. In one example hook parts of a waste bin liner are extended in sequence over and under a perimeter rim of a waste bin, and laterally inward of a part of the perimeter rim. In one example a rigid liner has multi-purpose hook parts that lock to the rim of a waste bin, and also form lifting handles for removing the liner from the bin.

1. A method comprising: inserting a rigid liner into a receptacle of a waste bin, the rigid liner conforming to an interior shape of the receptacle;extending a plurality of hook parts from the rigid liner in sequence over and under a perimeter rim of the waste bin to lock the rigid liner to the waste bin;in which each hook part connects to the rigid liner by a respective hinge; andin which each hinge has a hinge axis parallel to a part of a perimeter axis of the rigid liner that is adjacent the hinge, and extending further comprises rotating each hooking part in a downward direction into a locked position. 2. The method of claim 1 further comprising: unlocking the plurality of hook parts from the perimeter rim; andlifting the rigid liner from the waste bin by gripping the plurality of hook parts. 3. The method of claim 2 in which: the perimeter rim is formed by a bin ledge and a skirt, the bin ledge extended laterally outward from a top part of the waste bin, with the skirt depending from the bin ledge;each hook part has an arm with a hook tip that projects upward and laterally inward from the arm, and laterally inward of the skirt, when in the locked position; andeach hook tip and arm collectively define a finger receiving cavity that faces downward when in the lifting position. 4. The method of claim 3 in which each hook part has a range of motion about the respective hinge between the locked position and the lifting position, the range of motion being at least ninety degrees. 5. The method of claim 4 in which the range of motion is at least one hundred eighty degrees. 6. The method of claim 4 in which an end of each arm connects to the hinge axis, and the arm stands vertically upright when in the lifting position. 7. The method of claim 4 in which each finger receiving cavity comprises a plurality of finger receiving grooves. 8. The method of claim 4 in which rotation, past the lifting position in a direction away from the locked position, is limited by a stop associated with the respective hinge. 9. The method of claim 8 in which each stop comprises a projection from an exterior surface of the respective arm adjacent the hinge. 10. The method of claim 9 in which the projection has the shape of a triangle in a cross-sectional plane perpendicular to the hinge axis, in which an edge, of the triangle, that is closest to the hinge extends perpendicular to the exterior surface of the respective arm. 11. The method of claim 3 in which each hook tip has, in a cross-sectional plane perpendicular to the hinge axis, a curved exterior surface and a curved interior surface, the curved exterior surface and the curved interior surface converging together at a tip edge. 12. The method of claim 1 in which each hinge defines an outer lateral edge of a liner ledge, which is extended laterally over the perimeter rim. 13. The method of claim 1 in which a plurality of bags are nested within the rigid liner, each bag conforming to an interior shape of the rigid liner. 14. The method of claim 13 in which each bag forms first and second tabs that project out of a top part of the bag. 15. The method of claim 14 in which the first tabs of each bag are layered upon each other to form a first stack of tabs, the second tabs of each bag are layered upon each other to form a second stack of tabs and each bag forms third and fourth tabs that project out of the top part of the bag, the third tabs of each bag are layered upon each other to form a third stack of tabs, the fourth tabs of each bag are layered upon each other to form a fourth stack of tabs, and the first stack, second stack, third stack, and fourth stack are located adjacent respective top corners of the rigid liner. 16. The method of claim 13 in which the rigid liner contains a plurality of first parts, each being one of a male or female part and mounting a respective second part that is the other of a male or female part, and supporting one or more of the plurality of bags between the first part and the respective second part. 17. A combination comprising the rigid liner and waste bin of claim 1. 18. A method comprising: inserting a rigid liner into a receptacle of a waste bin, the rigid liner conforming to an interior shape of the receptacle;extending a plurality of hook parts from the rigid liner in sequence over and under a perimeter rim of the waste bin to lock the rigid liner to the waste bin, in which each hook part connects to the rigid liner by a respective hinge;unlocking the plurality of hook parts from the perimeter rim; andlifting the rigid liner from the waste bin by gripping the plurality of hook parts;in which: the perimeter rim is formed by a bin ledge and a skirt, the bin ledge extended laterally outward from a top part of the waste bin, with the skirt depending from the bin ledge;each hook part has an arm with a hook tip that projects upward and laterally inward from the arm, and laterally inward of the skirt, when in the locked position; andeach hook tip and arm collectively define a finger receiving cavity that faces downward when in the lifting position.
