Abstract

A folding menstrual cup comprising an outer cup body with a top accommodating cavity formed therein and a round opening provided on the top thereof and the bottom thereof being connected with a flow guiding pipe via a folding part at the side opposite to the opening; a flow guiding pipe providing with a pipe orifice communicating with the top accommodating cavity and a valve controlling communication to the pipe orifice; and a folding part being capable of protruding upward and enabling the top end of the flow guiding pipe to extend into the top accommodating cavity along with the folding part, and capable of straightening downward thereby a bottom accommodating cavity is formed inside the folding part. When in use, the folding part extends into the top accommodating cavity of the outer cup body and is placed in a body.

Claims

1. A folding menstrual cup comprising:

an outer cup body with a top and a bottom, wherein a top accommodating cavity is formed inside the outer cup body and a round opening is provided at the top of the outer cup body;

at a side opposite to the opening, the bottom of the outer cup body is connected to a flow guiding pipe via a folding part;

the flow guiding pipe with a pipe orifice in communication with the top accommodating cavity of the outer cup body, where a valve controlling communication to the pipe orifice is arranged on the flow guiding pipe; and

the folding part being capable of protruding upward and enabling the top end of the flow guiding pipe to extend into the top accommodating cavity of the outer cup body along with the folding part;

wherein the folding part is capable of straightening downward and a bottom accommodating cavity is formed inside the folding part.

2. The folding menstrual cup according to claim 1, wherein the folding part comprises a cup body end connected to the bottom edge of the outer cup body, and a catheter end connected to a top pipe orifice of the flow guiding pipe, and the aperture of the cup body end is greater than that of the catheter end.

3. The folding menstrual cup according to claim 1, wherein a plurality of ring-shaped bulges arranged closely one another are formed along an inner wall of the folding part, and a fold deformable by folding is formed between each two adjacent ring-shaped bulges.

4. The folding menstrual cup according to claim 3, wherein each of the ring-shaped bulges is provided with an arc surface which is raised toward the inside of the folding part.

5. The folding menstrual cup according to claim 1, wherein convex rings are provided respectively outside the top edge of the outer cup body and outside the bottom edge of the outer cup body.

6. The folding menstrual cup according to claim 1, wherein the valve comprises two flexible valve plates which extend out of a side wall of the pipe orifice in a directly-facing manner, and the two flexible valve plates are closely abutted.

7. The folding menstrual cup according to claim 6, wherein bosses which are bulged upward and are closely abutted are respectively formed at the tops of the two flexible valve plates, the abutting face of each flexible valve plate is a plane, and the outer side surfaces of the bosses are inclined planes which are inclined toward the abutting face.

8. The folding menstrual cup according to claim 1, wherein tactile bumps are arranged, outside to the valve position, on the outer wall of the flow guiding pipe.

9. The folding menstrual cup according to claim 1, wherein the outer cup body, the flow guiding pipe, the folding part and the valve are integrally formed into a silica gel product.
