Claims20
An adapter tool for paper rolls that do not have inner cardboard tubes, comprising:
- a hollow cylinder having a first end and a second end opposite the first end with a generally uniform diameter opening therebetween, wherein the first end has a chamfered edge uniformally about the first end, and the second end has an enlarged base having an outer diameter greater than the outer diameter of the hollow cylinder;
- and
- a spiral on the exterior surface of the hollow cylinder between the first end and the second end, and the spiral runs into the chamfered edge on the first end, wherein the first end is adapted to be pushed into a central opening of a paper roll that does not have an inner cardboard tube, and the hollow cylinder is able to be rotated by the second end until substantially all of the hollow insert is located inside the central opening of the paper roll.
A method of mounting paper towel rolls that do not have inner cardboard tubes, on paper dispensers, comprising the steps of:
- providing a paper roll with a central opening that does not have an inner cardboard tube, the roll being selected from a toilet paper roll and a paper towel roll;
- providing a cylinder having a tip end with a chamfered edge uniformally about the tip end, and an opposite end with an enlarged base;
- providing a spiral on an exterior surface of the cylinder between the tip end and the base, so that the spiral runs into the chamfered edge on the tip end;
- pushing and rotating the tip end of the base into the central opening of the paper roll with the enlarged base until the cylinder is substantially inside the central opening of the paper roll, and the enlarged base abuts against a side surface of the paper roll.
An adapter tool for paper rolls that do not have inner cardboard tubes, comprising:
- an elongated insert having a first end and a second end opposite the first end with a generally uniform diameter therebetween, wherein the first end has a chamfered edge uniformally about the first end, and the second end has an enlarged base having an outer diameter greater than the outer diameter of the elongated insert;
- and
- a spiral on the exterior surface of the elongated insert between the first end and the second end so that the spiral runs into the chamfered edge on the first end, wherein the first end is adapted to be pushed into a central opening of a paper roll that does not have an inner cardboard tube, and the elongated insert is able to be rotated by the second end until substantially all of the elongated insert is located inside the central opening of the paper roll.
