Collapsible menstrual cup

Abstract

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.

DETAILED DESCRIPTION

[0029] Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.

[0030] Referring to FIG. 1, a first isometric view of the collapsible menstrual cup is shown.

[0031] The collapsible menstrual cup 1 includes a rim 10 formed from a rim inner surface 12 and rim outer surface 14, with optional rim outer projections 16.

[0032] The reservoir 20 is formed from an exterior barrier 22 and an interior barrier 24. The exterior barrier 22 and interior barrier 24 are affixed to each other with a layer weld 26, thus creating a unified interior/exterior barrier 22/24 in any location where the barriers 22/24 are not separated by absorbent material 30 (location of which is marked in FIG. 1 as would be seen behind the interior barrier 24, see also FIGS. 8 and 9).

[0033] Perforations 28 allow menstrual fluid to pass through the interior barrier 24 and into the absorbent material 30.

[0034] The absorbent material 30 includes central segment 32 (see FIG. 8) and discrete segments 34. The absorbent material sits within pockets 36 where the exterior barrier 22 and interior barrier 24 are separated. The layer welds 26 surround the pockets 36, holding the absorbent materials 30 in position.

[0035] Referring to FIGS. 2, 3, 4, and 5, multiple side views of the collapsible menstrual cup are shown.

[0036] The collapsible menstrual cup 1 includes a rim 10 affixed to a reservoir 20.

[0037] Referring to FIG. 6, a top view of the collapsible menstrual cup is shown.

[0038] Again shown is the reservoir 20, with the interior barrier 24 permitting passage of fluids through perforations 28 to the absorbent material 30 formed from central segment 32 and discrete segments 34.

[0039] Note that this figure shows the collapsible menstrual cup 1 in an expanded position, resulting in segment separation 38 between the discrete segments 34. In particular, the discrete segments 34 are separated near the central segment 32, where the most expansion is required to open the collapsible menstrual cup 1.

[0040] Referring to FIG. 7, a bottom view of the collapsible menstrual cup is shown.

[0041] The rim 10 and reservoir 20 are visible.

[0042] Referring to FIG. 8, a cross-sectional view of the collapsible menstrual cup is shown.

[0043] The reservoir 20 is shown formed from an exterior barrier 22 and an interior barrier 24, joined at layer welds 26.

[0044] The absorbent material 30 includes central segment 32 and discrete segments 34 within pockets 36.

[0045] Segment separation 38 is again visible between discrete segments 34, which separate when the menstrual cup is opened downward, as shown by the arrow.

[0046] Referring to FIG. 9, a second isometric view with the outside layer hidden of the collapsible menstrual cup is shown.

[0047] The interior barrier 24 is shown with pockets 36 formed to hold the absorbent material 30 comprising central segment 32 and discrete segments 34.

[0048] Referring to FIG. 10, a view of the absorbent elements of the collapsible menstrual cup is shown.

[0049] The absorbent material 30 of the central segment 32 and discrete segments 34 is shown in a collapsed position. Note the consistent segment separation 38.

[0050] Referring to FIG. 11, a view of the outer layer of the collapsible menstrual cup is shown.

[0051] Prior to the layer welds 26 (see FIG. 8), the interior barrier 24 has a simpler shape. It is the welds to create the pockets 36 (see FIG. 8) that create the more complex shape of the final design.

[0052] Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.

[0053] It is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction, and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
