Abstract

A paper cutting apparatus comprising a housing partially enclosing a roll of paper and a cutting member disclosed along an opening of the housing. A leading edge of a roll of paper is unrolled through the opening of the housing and is linearly severed along the cutting member.

Claims

1. An apparatus for use with a roll of paper, said apparatus comprising:

a housing having a cross-section including an internal shape and an external shape, said internal shape adapted to partially enclose an outer surface of said roll, said length of said housing having a length that is about equal to the length of the roll and said housing is substantially longer than a diameter of said roll, said housing having an opening extending longitudinally for the length of said housing to allow a leading edge of said paper to be unrolled through said opening; and

said internal shape of said housing terminating in a first cutting member disposed along a first side of the opening of said housing to linearly sever a section of paper from said roll in a first cutting operation, wherein a first end of said first cutting member is in direct contact with the outer surface of said roll before, during, and after said first cutting operation, and wherein a second end of said first cutting member extends outwardly from said opening of said housing;

and wherein said housing and said first cutting member are integrally formed with no relative movement between said housing and said first cutting member at any time, including before, during, or after said first cutting operation;

and wherein the internal shape of said housing has a diameter substantially equal to the diameter of said roll to maintain said roll in its initial tightly wound state.

2. The apparatus of claim 1 wherein the internal shape of said housing is at least partially circular.

3. The apparatus of claim 1 wherein the cross-section of said housing comprises a uniform thin wall.

4. The apparatus of claim 3 wherein said housing comprises extruded plastic material having a uniform cross-section.

5. The apparatus of claim 1 wherein said first cutting member outwardly extends from said first side of said opening of said housing.

6. The apparatus of claim 5 wherein said first cutting member comprises a straight thin-walled member.

7. The apparatus of claim 1 further including a cutting means outwardly extending from said housing for at least a portion of the length of said housing for further linearly severing said section of wrapping paper along an outermost edge of said cutting means in a second cutting operation.

8. The apparatus of claim 7 wherein said cutting means is generally disposed on a second side of said opening.

9. The apparatus of claim 7 wherein said cutting means outwardly extends from a second side of said opening of said housing for performing said second cutting operation when said section of wrapping paper is placed between a flat surface and said cutting means by linearly severing said section at a point at which said cutting means contacts said flat surface.

10. The apparatus of claim 1 wherein the external shape of said housing is at least partially flat to allow said housing to rest on a flat surface in a stable fashion.

11. The apparatus of claim 10 wherein said first cutting member outwardly extends from said housing for substantially the length of said housing, said first cutting member disposed generally opposite from the partially flat side of said external shape.

12. The apparatus of claim 11 wherein said extends from said first side of said opening of said housing, said first side of said opening generally disposed opposite from said partially flat side of said external shape.

13. An apparatus for use with a roll of paper, said apparatus comprising:

a housing made of extruded plastic material and having a uniform cross-section including an internal shape and an external shape, said internal shape adapted to partially enclose an outer surface of said roll of paper for substantially the length of said roll, said housing having a length that is about equal to the length of the roll and said length of said housing is substantially longer than a diameter of said roll, said housing having an opening extending longitudinally for the length of said housing to allow a leading edge of said paper to be unrolled through said opening, said internal shape of said housing terminating in a first cutting member disposed along a first side of the opening of said housing to linearly sever a section of paper from said roll in a first cutting operation, wherein a first end of said first cutting member is in direct contact with the outer surface of said roll before, during, and after said first cutting operation, and wherein a second end of said first cutting member extends outwardly from said opening of said housing;

and wherein said housing and said first cutting member are integrally formed as a one-piece plastic extrusion with no relative movement between said housing and said first cutting member at any time including, before, during or after said first cutting operation;

and wherein the internal shape of said housing has a diameter substantially equal to the diameter of said roll to maintain said roll in its initial tightly wound state.

14. The apparatus of claim 13 wherein said first cutting member comprises a thin-walled member.

15. The apparatus of claim 13 further including cutting means outwardly extending from said housing for at least a portion of the length of said housing for further linearly severing said section of wrapping paper along an outermost edge of said cutting means in a second cutting operation.

16. The apparatus of claim 15 wherein said cutting means is generally disposed on a second side of said opening.

17. The apparatus of claim 16 wherein said cutting means outwardly extends from said second side of said opening of said housing.

18. The apparatus of claim 16 wherein the external shape of said housing is at least partially flat to allow said housing to rest on a flat surface in a stable fashion.

19. The apparatus of claim 18 wherein said cutting means outwardly extends from said second side of said opening, and wherein an outermost edge of said cutting means terminates at a point about in contact with said flat surface when said housing is resting on said partially flat external shape of said housing, for performing said second cutting operation when said section of wrapping paper is placed between the flat surface and said cutting means by linearly severing said section at a point at which said cutting means contacts said flat surface.
