Abstract

Menstrual cups and methods of use are described herein. An example menstrual cup may include a rim having at least one lip that extends about the rim and a receptacle defining a textured pattern. The textured pattern may include various lines and/or shapes. An example menstrual cup may be comprised of silicone or a similar material and can be worn during sexual intercourse.

First claim

What is claimed is:

1. A menstrual cup, comprising:
a rim having an upper portion, a lower portion, an exterior surface, a first end, a second end, a first side, and a second side, the rim defining a first lip adjacent the upper portion, the first lip extending along the exterior surface of the rim, the rim comprising silicone and having a substantially regular oval shape; and
a receptacle disposed adjacent and attached to the rim, the receptacle comprising silicone and defining an interior surface, the interior surface comprising a textured pattern defined solely by the interior surface, wherein a slope of a first end of the receptacle adjacent to the first end of the rim is less than a slope of a second end of the receptacle adjacent to the second end of the rim;
wherein the rim is integrally formed with the receptacle;
and wherein the first end of the rim extends away from the receptacle.

2. The menstrual cup of claim 1 , further comprising a second lip adjacent the lower portion, the second lip extending along the exterior surface of the rim.

3. The menstrual cup of claim 2 , wherein the rim defines a groove disposed between the first lip and the second lip.

4. The menstrual cup of claim 3 , wherein the first lip extends about the entire exterior surface of the rim.

5. The menstrual cup of claim 4 , wherein the second lip extends about the entire exterior surface of the rim.

6. The menstrual cup of claim 5 , wherein each of the first lip and the second lip is substantially semi-circular in cross-sectional shape.

7. The menstrual cup of claim 6 , wherein the first lip defines a first height and the second lip defines a second height; and
wherein the first height is substantially equal to the second height.

8. The menstrual cup of claim 7 , wherein the rim defines an interior surface that does not define a lip.

9. The menstrual cup of claim 3 , wherein the first side of the rim defines a first curved portion.

10. The menstrual cup of claim 9 , wherein the second side of the rim defines a second curved portion.

11. The menstrual cup of claim 10 , wherein the first end and the second end of the rim are configured to contact a flat surface when the rim is placed on said flat surface.

12. The menstrual cup of claim 11 , wherein neither the first curved portion nor the second curved portion is configured to contact said flat surface when the rim is placed on said flat surface.

13. The menstrual cup of claim 3 , wherein the rim defines a thickness extending from a top of the upper portion to a base of the lower portion; and
wherein the rim thickness is substantially uniform about the entirety of the rim.

14. The menstrual cup of claim 13 , wherein the rim further comprises a connecting portion that is integrally formed with the receptacle.

15. The menstrual cup of claim 14 , wherein the connecting portion defines a thickness; and
wherein the thickness is greater adjacent the second end than the first end.

16. The menstrual cup of claim 1 , wherein the receptacle extends from the first end to the second end of the rim.

17. A menstrual cup, comprising:
a rim having an upper portion, a lower portion, an exterior surface, a first end, a second end, a first side, a second side, and a curved portion, the rim defining a first lip adjacent the upper portion, the first lip extending along the exterior surface of the rim, the rim comprising silicone and having a substantially regular oval shape, the curved portion disposed adjacent said rim and tapering in side as it extends toward the first end from the second end; and
a receptacle disposed adjacent and attached to the rim, the receptacle comprising silicone and defining an interior surface, the interior surface comprising a textured pattern defined solely by the interior surface, wherein a slope of a first end of the receptacle adjacent to the first end of the rim is less than a slope of a second end of the receptacle adjacent to the second end of the rim;
wherein the rim is integrally formed with the receptacle;
and wherein the first end of the rim extends away from the receptacle.

18. The menstrual cup of claim 17 , wherein the receptacle extends from the first end to the second end of the rim.

19. The menstrual cup of claim 18 , further comprising a second lip adjacent the lower portion, the second lip extending along the exterior surface of the rim.

20. The menstrual cup of claim 19 , wherein the first lip defines a first height, the second lip defines a second height, and each of the first height and the second height is between 0.1 millimeters and 10 millimeters.
