Abstract
Abstract A holder for a paper towel roll or toilet paper roll. A stationary base member has an annular flat rim surrounding a central frustoconical projection. A rotatable member also has an annular flat rim surrounding a central hollow frustoconical projection that nests around the projection of the base member and is rotatable with respect thereto. The facing flat surfaces of the rim and the facing surfaces of the projections enable relative rotation with some resistance, to provide braking action. The outer surface of the frustoconical projection of the rotatable member includes means, such as splines, for firmly non-rotatably engaging the hollow core of a paper towel roll or toilet paper roll. The base member is secured horizontally, so that the rotatable member stands up vertically and holds the paper roll vertically.

Claim 1
Independent Claim
192 words
A paper towel roll holder, including in combination: a stationary base member having an annular horizontal rim surrounding a central frustoconical upwardly-extending protrusion, said rim having an upper surface on the same side as said protrusion and an adhesive-receptive surface on its other side, said protrusion having an outer surface, adhesive material adhered to said adhesive-receptive surface and able to adhere to a countertop, a rotatable member having an annular rim surrounding a central hollow frustoconical protrusion that nests around the protrusion of said base member and is rotatable with respect thereto, said rim having a surface facing the surface of said base member's rim, the outer surface of said frustoconical protrusion of said rotatable member acting as retention means for firmly non-rotatable engaging a hollow core of a paper towel roll, the facing surfaces of the two members being made low enough in mutual friction to enable relative rotation but having sufficient friction to result in a braking effect, whereby said base member can be adhesively adhered to a stationary horizontal supporting surface and wherein said rotatable member is removable from said base member and when installed is rotatable about it.
