Candida vulvovaginitis is one of the most frequent symptomatic infectious diseases of the lower genital tract in the world.1 Candida albicans is the most common infectious cause of vulvovaginitis. Though the most common cause of infections, C. albicans is diagnosed with a vaginal swab. Candida vaginitis typically involves the vagina and surrounding areas. However, Candida vulvitis is also a common problem. This condition involves the vulva with the vagina serving as a reservoir. Additionally, patients diagnosed with Candida vulvovaginitis (vulvitis) are typically also suffering from vaginitis.2 While the vulva is the area in which the symptoms are often expressed, the treatment must occur in the vaginal reservoir, i.e., the vaginal lumen, where the infection accumulates. Vulvovaginal candidiasis can be difficult to diagnose, and treatments may be ineffective. Approximately 75% of women suffer from the disease at least once in their lifetime.3 Some of these patients can be treated with a topical or oral antifungal drug, but others suffer from a chronic subtype, resulting in a moderate to severe disease which can inhibit their quality of life. 1Donders, Gilbert G.

The term a “breathable fabric” as used herein, refers to any fabric which allows the passage of air therethrough, including, but not limited to organic or non-organic cotton, spandex, jersey, mesh material, bamboo, or lace, among others, and may include, blends of various fabrics. The weight of the breathable fabric may include 7 oz per square yard weight or less in some areas. In some non-limiting embodiments, the weight of the fabric, at least in the genital region, may include 6 oz per square yard weight or less, and in some non-limiting embodiments, the weight of the fabric may include 5.4 oz per square yard weight. When the breathable fabric includes a mesh material or other knit material, it may include small apertures integrally knit within, in a non-limiting embodiment. The breathable fabric may include an absorbent material or a moisture wicking material. In other embodiments, no apertures may be included in the material or fabric.
The term “genital area” as used herein, includes but is not limited to an area of a user of the female gender, extending from the mons pubis to the sacrum, including the external genital organs, including specifically the mons pubis, labia majora, labia minora, the vaginal opening, and the vulva. In a user of the male gender, the genital area includes the external genital organs, including the penis, the male urethra and the scrotum. The male genital area also includes the rectum, and any external organs therebetween. Moreover, the male genital area also extends to the sacrum.
In view of the significant and pervasive problems caused by vaginitis and vulvitis, a treatment or prevention of these conditions is needed. Increased breathability and air to the vulva and vagina is necessary for good vulva and vaginal health. Consequently, in many of the embodiments discussed herein, at a minimum, a breathable fabric is used in the genital areas.
The fabrics described herein may include breathable or non-breathable fabrics in various regions of the undergarment as described. In some embodiments, the fabrics may include an absorbent material, a wicking material, or an elastic material. These materials may include natural and/or synthetic fibers, such as cotton, bamboo, hemp, silk, wool, rayon, polyester, cotton and polyester blend, elastane, rubber, nylon, nylon or polyester blends with or without elastane, polyethylene terephthalate, polypropylene, and other materials or combinations thereof. Various constructions of the materials may include various weaves, knits, including tricot, raschels, Milanese, powernets, ribs, meshes lockstitches, and single knits, doubleknits, ribs, jacquard, and plaited as well as spacer mesh (e.g., knit spacer mesh), among other constructions known to those skilled in the art.
Embodiments of the invention herein may include an undergarment having a single fabric layer (i.e., single-ply) in the genital region and may include other elements. Using a single fabric layer increases the breathability of the garment and allows enhanced airflow to the genital area. The embodiments may further include a lengthened genital region panel (i.e., a lower portion), which increases breathability to the forward genital area and rectal area. Specific manufacturing including stitching, such as a flat seam, in some embodiments, are required to attach a single fabric layer to the rest of the garment and to increase comfort, while maintaining support. The lower portion may include a breathable fabric, whether or not the other portions of the undergarment includes a breathable fabric. The embodiments differ from other undergarments at least in part by including a single panel in the genital area instead of the standard double layer panel design. The increased length of the genital panel may extend breathability to these sensitive areas. In addition to candida (yeast) vaginal infections as described above, as well as bacterial vaginosis, perirectal rashes are also very common. In postmenopausal women perineal rashes are common as a result of a decreased density of skin in this area. Garments with increased breathability in these areas are helpful in preventing or relieving these types of infections and rashes.
The lower portion 104 of the undergarment may be of the same material as the upper portion 102, or of another material as shown in
If the lower portion 104 and the upper portion 102 both include breathable material, the lower portion 104 may include a breathable material of a lower weight, or breathable material with a smaller denier (D) than the upper portion 102, for example. The lower portion 104 includes a breathable material and may include an open-weave mesh material, in a non-limiting embodiment. The material of the lower portion 104 and/or the upper portion 102 may include an absorbent material. Materials including lightweight, small denier, woven cotton, may be included to allow for adequate flow of air, but also distribution of moisture for evaporation in the lower portion 104 of the undergarment, and optionally, additionally, in the upper portion 102 of the undergarment.
In additional non-limiting embodiments, the lower portion 104, the upper portion 102, or both, may include an antimicrobially-treated fabric or material such as that described in U.S. Pat. No. 4,343,853, which is incorporated herein by reference, or a fabric or material with anti-microbial properties. In one non-limiting embodiment, the antimicrobial composition is a chlorinated phenoxy antimicrobial composition, and the fabric of at least the lower portion 104 of the undergarment 100 is pretreated with the composition by being subjected to the composition prior to being fabricated into the undergarment 100.
Several different embodiments for the waistband 120 secured to or formed of the top portion of the undergarment 100 may be provided. The waistband 120 is provided for holding the undergarment 100 on the user. In one embodiment, the waistband 120 may be constructed of a different fabric or material as the upper portion 102 and/or the lower portion 104, or of the same material of either of the upper portion 102 or the lower portion 104. In one non-limiting example, the waistband 120 may be formed of a lace material, in a further embodiment, the material may include a stretch lace. In another embodiment, the waistband 120 may include an elastic knit within the upper portion 102, in one example, wherein the elastic may include a loose elastic to provide for a comfort fit, while securing the undergarment 100 onto the user. Surrounding the openings 122, 124 for receiving the legs of a user may also include an elastic portion for securing the undergarment 100 onto the user in an embodiment. In a non-limiting embodiment, the elastic surrounding the openings 122, 124, and some of the elastic in other areas of the undergarment may include a thin elastic to enhance comfort of the user. In some embodiments, the elastic may include a rubber material. In a non-limiting example, the elastic includes a white natural elastic rubber tape, of dimension 0.15 in×¼ inch, product name PQW1514 sourced from State Narrow Fabrics, Inc. This elastic may be included in some particular embodiments for enhanced comfort of the user due to the light rubber in the elastic, resulting in decreased tensile strength.
Along the edges of the undergarment, and at the first seam 116 and second seam 118 joining the lower portion 104 to the upper portion 102 may include a flat seam to enhance the comfort of the undergarment 100, in an embodiment. In other embodiments, seams connecting various elements of the garment may be wide, narrow, loose, dense, bound seams, French seams, flat seams, top stitched seams, lapped seams, and superimposed seams. Flat seams may, for example, use a zig zag lock stitch, chain stitch, or covering stitch. Further, the seam may be any suitable width, such as 1 to 10 mm wide, generally 4 to 8 mm wide. The seam may be two separate seams (double seams) adjacent each other. Seams may be used that are not only functional but add a decorative or ornamental feature to the garment.
In at least one further embodiment, an undergarment may be included without the first and second seams, wherein the upper portion and lower portion of the device are formed of the same breathable fabric. In this embodiment, seams along the sides of the undergarment between the openings 122 and 124, and the top portion 110, respectively may be required to join the one piece of fabric together to form the undergarment 100.
In still another embodiment, only one of the first seam 116 or the second seam 118 may be required, wherein the lower portion 104 and a front side 106 are formed of one material, wherein only the second seam 118 connecting the upper portion 102, back side 108 to the remainder of the undergarment may be included, in addition to seams between the openings 122, 124 and the top portion 110, respectively. In yet another embodiment, only the first seam 116 may be required, wherein the lower portion 104 and a back side 108 are formed of one material, wherein only the second seam 118 connecting the upper portion 102, front side 106 to the remainder of the undergarment 100 may be included, in addition to seams between the openings 122, 124 and the top portion 110, respectively, for example.
The undergarment embodiments herein may include bikini, thong, full coverage underwear, or sports undergarments, for example, or may further include undergarment for males such as boxers, briefs, or unisex undergarments including base layers, compression garments, slider shorts, and/or swimwear.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art of molecular biology. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, suitable methods and materials are described herein.
