CONDOM WITH WRAPPING ADHESIVE FLANGES

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.

Claims

1. A condom that is divided into distal and proximal parts, wherein a. the distal part of the condom (towards closed end) comprises a tubular portion that covers the distal part of the penis; b. the proximal part of the condom (towards open end) comprises a circumferentially outstretched flange, wherein i. the said flange has adhesive coating on its internal or lower surface; ii. the said adhesive flange sticks onto the proximal part of the penis and onto itself to create a tubular covering, in continuum with the tubular portion, on the penis; iii. folds formed by the flange adhering onto itself are used as holding tags for the removal of the condom.

2. The condom as in claim 1, wherein the condom has a tubular portion and two adhesive flanges. It is made by sealing and cutting two thermoplastic films to create a pouch with a substantially hat shape seam, wherein there are two adhesive flanges extending from the said seam to emulate the configuration of claim 1.

3. The condom as in the claims above, wherein the adhesive coating is on the external or upper surface of the flanges, and the condom is inverted to turn the adhesive surfaces outside-in to emulate the configuration of claim 1.

4. The condom as in the claims above, wherein the closed end of the condom has a protrusion that serves as a seminal receptacle.

5. The condom as in the claims above, wherein the tubular portion and/or the adhesive flanges are supported by carrier films and/or releasing papers.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0019] In a preferred embodiment, the adhesive condom (FIG. 1) has a tubular portion 1 at the closed end and a circumferentially outstretched flange 2 (consists of anterior section 2A and posterior section 2B) at the open end. The flange 2 has adhesive coating, demarcated by adhesive margin 5, on the internal (or the lower) surface 6 (FIG. 2), and has an imaginary folding line 3 where the flange is folded into two halves (2A and 2B) at deployment. During deployment (FIG. 3), with or without the help of lubricant, the tubular portion 1 is donned over the distal part of the penis while both anterior flange 2A and posterior flange 2B are folded downward to adhere onto the proximal part of the penis 7 and onto each other (2A and 2B). The flange 2 now assumes a tubular shape in continuum with the tubular portion 1, with one or more protruding folds from the flange-to-flange adhesions (2A and 2B, FIG. 3). There are thus flange-to-flange (2a and 2B) and flange-to-penis (2 and 7) adhesions to provide a secure non-slip and non-spill deployment of the condom, even if the penis is not tumescent. Since the flange 2 is thin and flexible, the resultant protruding folds will not adversely interfere with sexual intercourse.

[0020] Because the tubular portion 1 is adhesive free, as demarcated by the adhesive coating margin 5 (FIG. 3), it spares the sensitive glans penis from possible painful removal of the adhesive flange 2 from the penis. In other words, the adhesive in the present embodiment is mainly in contact with the less sensitive skin of the penile shaft, not the sensitive glans penis.

[0021] The other benefit of the present invention is that the folds created by the flange-to-flange (2A and 2B) adhesions can be used as holding tags to enable easy removal of the condom.

[0022] In another embodiment, there is a seminal receptacle 4 at the closed end of the condom.

[0023] In yet another embodiment (FIG. 4), the condom is made by sealing and cutting two flexible thermoplastic films to create a pouch with a substantially inverted U shape seam 9 with extending seams 8 arising from both ends of the inverted U shape seam 9 (thus creating a substantially hat shape seam), and two flanges (2A and 2B) extending from the hat shape seam. The internal surfaces 6 of the two flanges (2A and 2B) are coated with adhesive. The U shape seam 9 forms the tubular portion 1 of the condom while its open end and the two extended seams 8 join the two adhesive flanges 2A and 2B to give an outstretched flanges' configuration similar to the embodiment as shown in FIG. 1. Likewise, at deployment (FIG. 5) the condom will have the similar configuration as described above (FIG. 3).

[0024] To ease manufacture processes, the adhesive may be coated on the external surfaces of the flanges 2A and 2B (FIG. 4). The tubular portion 1 is then inverted to turn the flanges (2A and 2B) outside-in to internalize the adhesive surfaces prior to deployment.

[0025] To make the flimsy tubular portion 1 and the adhesive flange 2 more manageable during production and deployment, both may be supported by more rigid carrier films and/or releasing paper, both of which are to be removed during the condom's deployment on the penis 7.
