  • Patent number: 10279997
    Abstract: Various trash can assembly embodiments are disclosed. In some embodiments, the trash can assembly includes a body and a lid assembly. The lid assembly can include a lid, and a multicomponent trim ring. The lid assembly can be rotatably connected with the body via a hinge unit. In certain embodiments, a flange of the trim ring is guided into and/or received into the hinge unit. A translating pin of the hinge unit can engage into the flange, thereby providing a rotatable connection between the trim ring and the body. In various embodiments, the translating pin is coupled with a handle to facilitate movement of the pin by a user during engagement of the trim ring and the hinge unit. A positioner can help to position the trash can against or adjacent to a wall or other structure. The movement of both the trim ring and the lid can be dampened.
