Description

SUMMARY

The present disclosure is directed to a reusable cup for collecting catamenia having a base, outer and inner walls, apertures, ribs, and ridges. In some examples, the reusable cup includes a trimmable stem. In some further examples, the reusable cup includes a circumferential band.

BACKGROUND

The present disclosure relates generally to feminine hygiene products. In particular, reusable menstrual cups for collecting and disposing of catamenia are described.

Known menstrual cups are not entirely satisfactory for the range of applications in which they are employed. For example, existing menstrual cups can be difficult to use, are uncomfortable, and prone to leaking. They are also difficult to properly clean and sterilize and tend to become dislodged during exercise or other movement. Other cups can be painful to remove because they provide improper suction that does not break at the top of the cup where the seal is formed.

What is needed is a reusable cup for collecting catamenia that fits the needs of women without compromising comfort, health, or the environment. Ideally, such a cup is a comfortable, reusable alternative to disposables like pads and tampons. It should be made with FDA approved materials and have no hidden chemicals. In addition, it should offer extended leak-proof protection and stay positioned during mild to strenuous activities without causing any irritation at the base of the cup near the vaginal opening while activities are being performed. It should provide improved suction that may be broken more easily and more comfortably. It should be capable of being pinched at the base, have ribs and ridges on the inside that can work in tandem with apertures to break suction and improve comfort when being inserted, worn, and removed.

Thus, there exists a need for cups for collecting catamenia that improve upon and advance the design of known menstrual cups. Examples of new and useful menstrual cups relevant to the needs existing in the field are discussed below. The present invention includes features that improve leak protection, placement and retention, removal efficiency, storage, portability, and comfort.

The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.

With reference to FIG. 1, a first example of a reusable cup for collecting catamenia, cup 100, will now be described. Cup 100 is a menstrual cup that functions to collect catamenia during a woman's menstrual cycle. Cup 100 addresses many of the shortcomings existing with conventional menstrual cups. For example, it comprises a double seal for leak protection, ridges and ribs that aid and hold the expansion of the cup in situ, and a unique ergonomic grip and pinch feature at the base that allows it to be removed and in an efficient and comfortable way. It also includes a unique receptacle that houses a trimmable stem. Further, its overall shape aids in the securement of the cup while the user is active. The present invention further comprises collapsibility for easy insertion, removal, and storage and is designed specifically to minimize movement and irritable rubbing within the body of the user. Finally, in alternative embodiments (not shown) cup 100 may include a uniquely designed storage case for effective storage between uses.

Thus, from the following figures and their descriptions, the reader will appreciate that the present invention is an improved receptacle for collecting catamenia. The reader will appreciate that cup 100 substantially comprises a comfortable, durable, reusable, leak-proof receptacle in which catamenia is collected and transported to an appropriate waste receptacle. In order to use cup 100, the user will collapse cup 100 on the vertical plane and insert it into the vagina. Cup 100 will naturally expand and conform to the user's unique shape and stay in place via gentle suction between the vaginal wall and the outside of cup 100. When the user wishes to remove cup 100, she will collapse cup 100 and break the gentle suction between cup 100 and the vaginal wall and pull cup 100 downward and out of the vagina. She may then empty the contents, sterilize cup 100, and store it in a uniquely configured antimicrobial storage case where it will remain safe and sterile until its next use. POD

As shown in FIG. 1, cup 100 includes a top 101, a lip 102, a bottom 103, an outer wall having an outer wall base (110, 111, respectively), and an inner wall having an inner wall base (130, 131, respectively, with inner wall 130 being shown in more detail in FIG. 3 and inner wall base 131 being shown in more detail in FIG. 5). Cup 100 further comprises a plurality of ridges 132, a plurality of ribs 150, a plurality of apertures 140, and in some embodiments, a stem 160. Cup 100 also comprises a receptacle 165 (shown in better detail and described in FIG. 5). In some embodiments, lip 102 further comprises lip extension 104 (shown in FIG. 3), which comprises a slightly thinner structural width than lip 102 itself. The reader will appreciate that lip 102 comprises a portion of smooth, rounded protruding silicone that is thicker than outer wall and inner wall (110 and 130, respectively) to ensure that cup 100 will open after being folded and inserted and will retain insertion position. In this manner, cup 100 provides increased comfort by preventing rubbing near the opening of the vaginal cavity.

In the example shown in FIG. 1, outer wall base 111 is located on outer wall 110 on the cup bottom 103 and is a substantially rounded hourglass configuration. It should be understood that, in alternative embodiments, the configuration of cup 100, outer wall 110, and outer wall base 111 may comprise a cylindrical, conical, or other suitable shape sufficient to accomplish cup 100's purposes. In still further embodiments, the shape of outer body 100 may be custom-fitted to each individual user's unique biological measurements. In this manner, it is an object of the present invention to accommodate users of varying body types. Further, the reader will appreciate that outer wall 110 and inner wall 130 are substantially congruous whereby inner wall 130 is adjacent to the inside of cup 100. Thus, outer wall 110 and inner wall 130 form the body of the cup and work in concert such that inner wall 130 forms the inside of cup 100 and comprises a fillable void that is designed to collect catamenia during menses while outer wall 110 forms the outside of the cup in contact with the vaginal wall.

The reader will also appreciate that the components of cup 100 may comprise thin pliant material to aid in flexibility and movability of the cup within the vaginal cavity. In a preferred embodiment, cup 100 is made of a non-toxic, hypoallergenic, elastomeric material such as medical grade silicone. In this manner, cup 100 provides increased flexibility and movability that permits it to conform to the unique shape of each individual user without the need for customization. However, as mentioned above, the dimensions of cup 100 make it capable of being customized should the user's biology and/or body type require it. It should also be understood that it is an object of the present invention that the components of cup 100 are designed to conforms to the natural shape of an individual woman without caving or folding and retains enough structural integrity to remain open to prevent leakage, but pliant enough to conform and move with the user's body. Thus, the reader will appreciate that the components of cup 100 (described in the following figures) work in concert to prevent catamenia from leaking from the vagina during menses. Thus, cup 100 presents a substantial improvement over existing menstrual cups because it is pliant enough to be opened, firm enough to remain opened and prevent leakage, but soft enough to conform and move with the body of the user. Finally, in some embodiments, there may be a gradient decrease in thickness of material of the cup towards the horizontal center, while the lip and base portions remain thicker.

Referring now to FIG. 2, an alternative view of the cup 100 is shown depicting outer wall 110. As can be seen in FIG. 2, and as mentioned above, the components of the outside of cup 100 include outer wall 110, outer wall base 111, lip 102, the plurality of apertures 140 and stem 160. It should be understood that, in alternative embodiments (not shown), stem 160 is an optional feature and its presence or absence does not affect the overall effectiveness of cup. Finally, the outside of cup 100 further comprises a plurality on indentation 112 having indicia 113 and lip extension 104.

With respect to the plurality of aperture 140, FIG. 2 depicts two of the plurality of apertures 140, however it is an object of the present invention that more or less aperture 140 may be employed. In a preferred embodiment of cup 100, the plurality of aperture 140 comprises three apertures 140. As can be seen in the embodiment according to FIG. 2, each of said plurality of aperture 140 is positioned around the perimeter of top 101 and slightly below lip 102 on lip extension 104. Each of the said plurality of apertures 140 comprises a channel traversing outer wall 110 and inner wall 130 on the horizontal plane (shown in FIGS. 1 and 3). In a preferred embodiment, each aperture may be formed at an angle through the thickest part of outer wall 110 and inner wall 130 beneath lip 102. In this manner, each aperture 140, in combination with outer wall 110, inner wall 130, and rib 150 functions to provide improved suction and suction-release upon insertion and removal of cup 100 (discussed in further detail below).

FIG. 2 also illustrates a plurality of indentation 112. As can be seen, indention 112 may be positioned to substantially circle outer wall base 111 as shown By way of example, FIG. 2 shows the number of indentions to be three, which is the preferred embodiment, however it is an object of the present invention that more or less indentation 112 may be utilized according to the user's body type and needs. However, it should be understood that the number of indention is at least two in any embodiment of cup 100.

The reader will appreciate that it is an object of the present invention for each indentation to provide a suitable means for the user to grasp cup 100 for insertion and removal. Further, by way of example, FIG. 2 depicts indentation 112 to be substantially ovoid in shape, however it is an object of the present invention that indentation 112 may be of any shape (such as circular, rectangular, triangular etc.) sufficient to permit the user to properly grasp and collapse cup 100 in situ for effective suction break of aperture 140 and removal of cup 100. Thus, when the user wishes to remove cup 100, she will gently pinch a first indentation 112 against a second indentation 112, thus decreasing the inner volume of cup 100. In this manner, air enters aperture 140, suction is broken, and the cup may be removed. Thus, cup 100 functions to create a superior seal with the walls of the vagina when cup 100 is in use.

In a preferred embodiment, indentation 112 comprises a thickened area of elastomeric material on inner wall base 131 and comprises slightly thicker elastomeric material on outer wall base 111. As can be seen, each of the plurality of indentation 112 circles bottom 103. Further, indentation 112 may comprise a thickened area of elastomeric material that continues from bottom 103 upward to the approximate vertical center of the cup body to allow full expansion when in use.

Further, indentation 112 may comprise a plurality of indicia 113. In the embodiment according to FIG. 2, indicia 113 comprises three, semicircular raised portions that will make pinching, gripping and removing the cup more ergonomic for the fingers. In this manner, indentation 112 provides an ergonomic fit to facilitate insertion and removal of cup 100. The reader will appreciate that the current form of indicia 113 is by way of example only. In alternative embodiments (not shown), at least one of the plurality of indentation 112 may further comprise indicia 113 such as whorls, patterns, or other indicia that provide a graspable portion of indentation 112. The reader will also appreciate that the preferred embodiment of cup 100 does not require indicia 113 to be uniform with respect to each indentation 112. It is an object of the present invention that indicia 113 may comprise indentations, raised portions, or other suitable patterns that may or may not change from indentation to indention. In this manner, cup 100 allows the user to more easily pinch bottom 103 to break suction for removal of cup 100. In a preferred embodiment, bottom 103, outer wall base 110, and indentation 112 are rounded and smooth for comfort, but are structured such that indentation 112 is set off from outer wall base 111 such that a grip can be made with the users fingers.

Finally, in some embodiments, (not shown) outer wall 110 may further comprise textures, indentations, or other indicia that facilitate gripping and removal of cup 100 and prevent slipping. In still further embodiments, outer wall 110 and inner wall 130 may comprise a matte finish that is moderately transparent to enable the user to determine the amount of catamenia collected. In still further embodiments, outer wall 110 and inner wall 130 may comprise a thinner structural width than the remaining components of cup 100. In this manner outer wall 110 and inner wall 130 increase cup 100's flexibility and movability within the vaginal cavity. Thus, the user is better equipped to break the suction seal of cup 100 in situ and accomplish facilitated removal.

With reference to FIGS. 3 and 4, perspective (FIG. 3) and bisected (FIG. 4) views of cup 100 are shown, depicting inner wall 130. In a preferred embodiment, inner wall 130 and outer wall 110 comprise a thicker structural width than the remaining components of cup 100. As can be seen in FIG. 4, and as mentioned above, outer wall 110 and inner wall 130 are congruous such that the former comprises the outside of the cup and the latter comprises the inside of the cup.

As shown in FIGS. 3 and 4, cup 100 further comprises a plurality of ridge 132 and a plurality of rib 150 (also shown in FIG. 1). As can be seen, the plurality of rib 150 and the plurality of ridge 132 may be positioned around the perimeter of inner wall 130. In the present embodiment, each of the plurality of ridge 132 is located on inner wall 130 between indentation 112 as shown. Further, each ridge 132 extends from inner wall base 131 to approximately the vertical center of cup 100. In alternative embodiments (not shown), more or less of each of said plurality of ridge 132 may extend from inner wall base 131 to approximately the vertical center of cup 100, in still further embodiments (not shown), one or more of the plurality of ridge 132 may extend from inner wall base 131 to lip 102. The reader will appreciate that the plurality of ridge 132 functions to facilitate expansion of cup 100 and provide improved gripping means when the plurality of indentation 112 is depressed for cup 100 insertion.

By way of example, the figures depict the number of ridge 132 to be three, however more or less ridge 132 may be included within the present invention according to the user's needs. It should be understood that it is an object of the present invention that the number of ridges may vary according to the user's needs. In alternative embodiments (not shown) ridge 132 may be omitted from the device. In still alternative embodiments (not shown) a second plurality of ridge 132 may be positioned around the perimeter of outer body 110.

FIGS. 3 and 4 also depict a plurality of rib 150. As can be seen, each of the plurality of rib 150 is located on inner wall 130, positioned to intersect each of the said plurality of indentation 112 terminating at lip 102. By way of example, FIG. 3 shows the number of ridge 132 and rib 150 to be 3, however it is an object of the present invention that more or less ribs and ridges may be utilized according to the user's body type and needs. In a preferred embodiment, rib 150 comprises a raised portion a long raised piece thickened material traversing inner wall 130. By way of example, FIG. 3 shows the number of ridge 132 and rib 150 to be 3, however it is an object of the present invention that more or less ribs and ridges may be utilized according to the user's body type and needs. In a preferred embodiment, rib 150 comprises a raised portion a long raised piece thickened material traversing inner wall 130.

According to the embodiment in the present figures, each of plurality of rib 150 may substantially circle inner wall 130 and may be substantially adjacent to each of the plurality of ridge 132 as shown. In a preferred embodiment, the number of rib 150 is equal to the number of aperture 140 and ridge 132 and may be substantially perpendicular to and extend downward away from aperture 140. In this manner, rib 150 works in tandem with aperture 140 to redirect ventilation from the aperture to a substantially lower point on cup 100, thereby facilitating release of suction and removal of cup 100 within the user's body. The finger indentions on the outer base in concert with the vertical ribs aid in the suction release when the cup is pinched at the base by releasing suction at the apertures at the top of the cup. In this manner, the overall volume of cup 100 is not as compromised when suction is released. The user will appreciate that the gentle suction that keeps cup 100 in place in situ is improved and release of the same is improved.

Finally, cup 100 may further comprise stem 160. As can be seen, stem 160 be located within receptacle 165 substantially in the center of outer wall 110. In the present embodiment, stem 160 may comprise a flattened tab, however it is an object of the present invention that stem 160 and in other embodiments it may comprise a ring, a nub, or other configuration sufficient to facilitate grasping of outer wall base 111.

The reader will appreciate that stem 160 may used to locate the cup in situ and may be used in conjunction with outer wall base 111 to assist the user with breaking suction and removing the cup. Thus, stem 160 provides an additional means for cup 100 to be easy to reach and remove. Further, it should be understood that stem 160 comprises pliant material that is soft and flexible such that bruising, chafing, rubbing, or other irritation of the vaginal cavity is minimized. In some embodiments, stem 160 may further compromise indicia 161 that provide instructions to trim the stem for customization to the individual user's body or to provide increased gripping capabilities for removal of cup 100. In the present embodiment, stem indicia 161 comprise a plurality of slightly raised and rounded lip in increments on the stem to aid in grip-ability of the stem. In alternative embodiments (not shown) indicia 161 may comprise notches, nubs, markings, or any other indicia suitable for its intended purpose.

Referring now to FIG. 5, a plan view of cup 100 is shown depicting receptacle 165 and stem 160 is shown. As can be seen, receptacle 165 comprises a repository that is substantially located in the bottom center of cup 100 and whereby the recess is capable of housing stem 160. In the present embodiment, receptacle 165 functions to permit trimming stem 160 but maintain a smooth base for the comfort of the user. In this manner, if the user wishes to remove stem 160 completely, she may do so by safely trimming it to the inside of receptacle 165, thus preventing any harmful and/or uncomfortable jagged edges from coming in contact with the vaginal wall or opening.

Based on the preceding description, the reader will appreciate that, when in use, cup 100 is folded or compressed and is inserted into the user's vagina and functions to ensure cup 100 will expand back to the unfolded configuration. When in situ, cup 100 is placed in the vaginal canal such that it is substantially facing the cervix while lip 102 remains in contact with the vaginal walls via gentle suction.

Turning attention finally to FIGS. 6 and 7, a second example of a reusable cup for collecting catamenia, cup 200 will now be described. Cup 200 includes many similar or identical features to cup 100. Thus, for the sake of brevity, each feature of cup 200 will not be redundantly explained. Rather, key distinctions between cup 200 and cup 100 will be described in detail and the reader should reference the discussion above for features substantially similar between the two cups.

As can be seen in FIG. 6, cup 200 includes band 210. As can be seen, band 210 may be built into the inner wall 130 substantially near the horizontal center of cup 100. In this manner, band 210 facilitates the use of a thinner width of inner wall 130. In this manner, cup 100 may be collapsed for insertion, provides support for inner wall 130 and outer wall 110, and facilitates proper expansion of cup in situ. In a preferred embodiment, band 210 may be implemented in a cross section of inner wall 130 as shown. In alternative embodiments, band 210 may be positioned in other configurations before insertion, such as for example, vertically, accordion style, or any other folding configuration capable of collapsing cup 200 according to the user's body type and specific needs. It should be understood that it is an object of the present invention that band 210 acts as an additional means to help the cup fully expand once in situ. Band 210 also acts as an additional seal for leak protection.

As mentioned above, for the sake of brevity, each feature of cup 200 will not be redundantly explained. Rather, key distinctions between cup 200 and cup 100 will be described in detail and the reader should reference the discussion above for features substantially similar between the two cups. Thus, the reader will appreciate that cup 200 comprises a plurality of rib 150, ridge 132, and aperture 140. However, in the embodiment according to FIGS. 5 and 6, it can be seen that band 210 bisects cup 200. Thus, the plurality of ridge 132 extends from the base of cup 200 in a similar manner as cup 100, however, each of the plurality of ridge 132 terminates at band 210 as shown. In alternative embodiments (not shown) one or more of the said plurality may terminate near the vertical center of cup 100. In still further embodiments, one or more of said plurality may terminate at lip 102. Similarly, the plurality of rib 150 begins at the top of indentation 132 (as opposed to the base of cup 100 as discussed in the preceding figures) and terminates at the lip in the manner described above.
