  • Publication number: 20200054480
    Abstract: A condom comprises a distal non-adhesive tubular portion 1 and a proximal circumferentially outstretched adhesive flange 2. The tubular portion 1 covers the distal part of the penis, whereas the adhesive flange 2 wraps around and sticks onto the proximal part of the penis to prevent slippage and leakage of the condom. The folds created by the flange (2A and 2B) adhering to itself are used as holding tags to ease the condom's removal. The condom may be produced by sealing and cutting two thermoplastic films to create a pouch with a substantially hat shape seam, and two adhesive flanges (2A and 2B) extending from the seam to emulate the above configuration. The adhesive coating may be on the external surface of the flanges and the condom is inverted outside-in to emulate the above configuration.

  • Patent number: 10258497
    Abstract: The present invention is a female condom with an extended shield that can cover and seal the external genitalia to prevent sperm and disease transmissions during coitus. The construction of the present invention involves sealing of the double layered membranous films in an omega or similar shape to create a tubular and a shield portions, followed by applications of adhesive and releasing sheets onto the exterior of both shields before it is cut into the final product. The tubular portion will form the protective barrier for vagina (condom) while the shield portion, which adheres to the external genitalia, will prevent the seepage of body fluid. The tubular portion may be inverted to serve as a male condom. Double tubular portions are constructed for unconventional sexual activities. Transverse and longitudinal folds are created to enlarge the tubular portion. The female condom may be shaped, textured, colored and flavored according to the users' demand.

  • Publication number: 20170239077
    Abstract: The present invention is a non-rolled adhesive condom with adhesive coating on its external surface supported by one or more releasing strips, a configuration that allows easy manufacture and deployment of said condom. Deployment involves donning the external surface of the closed end of said condom onto penis and pulling the releasing strips proximally and away from said condom, thereby inverting the adhesive coated external surface outside-in to adhere to penis. The condom may be constructed by sealing two or more membranes, even with the supporting films on. The tip of the closed end of condom has an adhesive-free area to serve as seminal receptacle. It can be opened to aid deployment of urinary condom catheter. Based on the above principle, a number of shortened non-rolled adhesive condoms (abbreviated condoms) comprising a seminal receptacle and adhesive flange(s) that wrap around the distal part of penis are also presented.
