Collapsible menstrual cup
View Patent ↗The collapsible menstrual cup prevents spillage by absorbing menstrual fluids. Separating the absorbent elements into discrete pieces allows for a nested, collapsed, flat state, and an expanded, separated state. Discrete pieces being individual elements able to move with respect to each other, in contrast to a unified layer of material that would fold when moved from a flat shape to a cupped shape. Thus, storing multiple devices on one's person is simplified without compromising functionality. The absorbent elements are shaped like flower petals, radiating outward from a central point. At the center is an optional central absorbent element. In the collapsed position the absorbent elements take positions in close proximity, nesting next to each other. In the expanded position for use, the absorbent elements spread out, allowing the reservoir to expand, preparing for use.
1. A menstrual cup comprising:
an exterior barrier;
an interior barrier;
a plurality of absorbent elements placed between the exterior barrier and the interior barrier;
the exterior barrier affixed to the interior barrier where not separated by the plurality of absorbent elements;
a rim affixed to the exterior barrier;
whereby the plurality of absorbent elements absorbs menstrual fluid.
2. The menstrual cup of claim 1 , wherein the interior barrier is an impermeable material with openings to allow menstrual fluid to pass through to the plurality of absorbent elements.
3. The menstrual cup of claim 1 , wherein the absorbent elements are discrete and unattached to each other.
4. The menstrual cup of claim 1 , further comprising:
a central absorbent element.
5. The menstrual cup of claim 1 , wherein the menstrual cup has a first position and a second position:
the first position being substantially flat, with the interior barrier, exterior barrier, and plurality of absorbent elements fitting substantially within a thickness of the rim; and
the second position forming a substantially cup-shaped reservoir, with the interior barrier and exterior barrier extending out a bottom of the rim to catch menstrual fluid.
6. A menstrual cup with a collapsed state and an expanded state, the menstrual cup comprising:
two or more disconnected absorbent elements;
the two or more disconnected absorbent elements held in position with respect to each other by being sandwiched between an exterior barrier and an interior barrier;
the collapsed state where the two or more disconnected absorbent elements are in a first position;
the expanded state where the two or more disconnected absorbent elements are in a second position;
whereby the disconnected absorbent elements absorb menstrual fluid.
7. The menstrual cup of claim 6 , wherein the interior barrier is an impermeable material with openings to allow menstrual fluid to pass through to the disconnected absorbent elements.
8. The menstrual cup of claim 6 , further comprising:
a central absorbent element.
9. The menstrual cup of claim 6 , wherein:
when in the first position, the menstrual cup is substantially flat, with the interior barrier, exterior barrier, and the disconnected of absorbent elements fitting substantially within a thickness of the rim; and
when in the second position, the menstrual cup is a substantially cup-shaped reservoir, with the interior barrier and exterior barrier extending out a bottom of the rim to catch menstrual fluid.
10. A collapsible menstrual cup comprising:
an absorbent material;
the absorbent material divided into two or more discrete and separate elements;
the absorbent material between an external layer and an internal layer;
the external layer being impermeable to liquids;
the interior layer allowing liquids to pass through from an interior to the absorbent material;
whereby separation of the absorbent material into two or more discrete and separate elements creates a flexible menstrual cup that can be configured into a small collapsed shape.
11. The menstrual cup of claim 10 , wherein the internal layer is an impermeable material with openings to allow menstrual fluid to pass through to the discrete absorbent elements.
12. The menstrual cup of claim 10 , wherein the two or more discrete and separate elements of absorbent material are unattached to each other.
13. The menstrual cup of claim 10 , further comprising:
a central absorbent element.
14. The menstrual cup of claim 10 , wherein the menstrual cup has a first position and a second position:
the first position being substantially flat, with the internal layer, external layer, and the absorbent material fitting substantially within a thickness of a rim; and
the second position forming a substantially cup-shaped reservoir, with the internal layer and external layer extending out a bottom of the rim to catch menstrual fluid.
