  • Patent number: 12133617
    Abstract: A dispenser for rolled paper includes a shell mounted to a spindle assembly which is mounted to a wall for convenient access in a bathroom or other facility. The dispenser also includes a lid assembly mounted to the shell and spindle assembly for rotational or pivotal movement to and between closed and open configurations. When in the closed configuration, a free edge of the paper roll may be pulled from the roll and the roll rotates on the spindle assembly for dispensing the paper. The paper roll may be inspected and/or replaced by rotation of the lid assembly about a pivot pin to an open configuration. Cooperating cam and cam surfaces and the bias of a spring on the pivot pin urge the lid assembly away from the shell during rotation toward the open configuration to allow for proper clearance and positioning of the lid assembly relative to the shell.
