Claims

1. A device adapted to be worn on a human finger to relieve the wearer of the urge to smoke, the device comprising:a first portion and a second portion that cooperate to define an opening having an axis and sized to receive a human finger;a cylindrical-shaped feature at the second portion, the cylindrical-shaped feature being oriented so that an axis thereof is perpendicular to the axis of the opening, the cylindrical-shaped feature being configured so as not to be capable of securing a cigarette.

2. The device according to claim 1, wherein the opening has an arcuate boundary portion defined by the first portion and a straight boundary portion defined by the cylindrical-shaped feature.

3. The device according to claim 1, wherein the cylindrical-shaped feature is immovable on the second portion.

4. The device according to claim 1, wherein the cylindrical-shaped feature is a solid cylinder.

5. The device according to claim 1, wherein the cylindrical-shaped feature comprises a tube surrounding the second portion such that a portion of the cylindrical-shaped feature defines a straight boundary portion of the opening.

6. The device according to claim 1, wherein the cylindrical-shaped feature has a cross-sectional diameter larger than the maximum cross-sectional thickness of the first portion of the device and smaller than the maximum width of the opening.

7. The device according to claim 1, wherein the cylindrical-shaped feature has oppositely-disposed first and second ends that define a length therebetween, and the length of the cylindrical-shaped feature is longer than a maximum outer diameter of the first portion.

8. The device according to claim 7, wherein the first end of the cylindrical-shaped feature defines a protrusion that extends beyond an outer boundary of the first portion.

9. The device according to claim 1, wherein the first portion defines a partial toroid adjoining the second portion at first and second locations.

10. The device according to claim 9, wherein the second portion is arcuate and entirely enclosed by the cylindrical-shaped feature.

11. The device according to claim 9, wherein the second portion is entirely defined by the cylindrical-shaped feature.

12. The device according to claim 11, wherein the cylindrical-shaped feature has oppositely-disposed first and second ends and a midportion therebetween, and the partial toroid adjoins the second end and the midportion of the cylindrical-shaped feature.

13. The device according to claim 1, wherein the first portion is defined at least in part by an axis of curvature that coincides with the axis of the opening.

14. The device according to claim 1, wherein the device has a d-shaped cross-section in a plane perpendicular to the axis of the opening.

15. A device adapted to be worn on a human finger to relieve the wearer of the urge to smoke, the device comprising:an arcuate portion; anda solid cylindrical portion immovable relative to the arcuate portion and cooperating with the arcuate portion to define an opening having an axis and sized to receive a human finger, the cylindrical portion being oriented so that an axis thereof is perpendicular to the axis of the opening, the cylindrical portion having oppositely-disposed first and second ends that define a length therebetween, the length of the cylindrical portion being longer than a maximum outer diameter of the arcuate portion such that the first end of the cylindrical portion defines a protrusion that extends beyond an outer boundary of the arcuate portion;wherein the cylindrical portion is configured so as not to be capable of securing a cigarette.

16. The device according to claim 15, wherein the opening has an arcuate boundary portion defined by the arcuate portion and a straight boundary portion defined by the cylindrical portion.

17. The device according to claim 15, wherein the cylindrical portion has a cross-sectional diameter larger than the maximum cross-sectional thickness of the arcuate portion and smaller than the maximum width of the opening.

18. The device according to claim 15, wherein the arcuate portion defines a partial toroid adjoining the second end of the cylindrical portion and adjoining a midportion of the cylindrical portion between the first and second ends thereof.

19. The device according to claim 15, wherein the arcuate portion is defined at least in part by an axis of curvature that coincides with the axis of the opening.

20. The device according to claim 15, wherein the device has a d-shaped cross-section in a plane perpendicular to the axis of the opening.
