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.

[0040] FIG. 5a: Sectional view of urinary condom 13 duly deployed onto penis 5 with the aid of adhesive condom 1, which adhered to both the condom 1 and penis 5 to give a leak proof seal.
[0041] FIG. 6: Sectional view of a preferred embodiment of adhesive abbreviated condom deployed onto penis 5. The abbreviated condom only comprises a seminal receptacle 4a and an adhesive flange 1b that covers solely the distal part of penis 5a. The adhesive abbreviated condom may simply be a shortened version of said non-rolled adhesive condom.
[0042] FIG. 7: Perspective view of a shortened version of said no rolled adhesive condom 1 with opposing side wall opened, while leaving the closed end 4 and seminal receptacle 4a intact, thereby creating two adhesive flanges 1b supported by releasing strips 3.
[0043] FIG. 8: Perspective view of the abbreviated condom as in FIG. 7, wherein the external adhesive coating 2 is partially exposed as the condom is opened up for deployment. In this configuration, the two flanges 1b are jointed at the closed end 4 and at the dome of seminal receptacle 4a. Loose ends 3a of the releasing strips 3 are used as pulling tags to deploy the condom.
[0044] FIG. 8a: Perspective view of the abbreviated condom as in FIG. 8 duly deployed onto glans penis 5a. The seminal receptacle 4a is inverted during deployment. Note that the area immediately surrounding the open end of seminal receptacle 4a, demarcated by adhesive margin 2a, is adhesive-free to accommodate external urethral meatus 5b.
[0045] FIG. 9: Perspective view of a preferred embodiment of abbreviated condom comprising two ultra thin membranes 1a adhere 2 together, with a substantially centrally located adhesive-free area demarcated by adhesive margin 2a, to form seminal receptacle 4a at the upper portion, and two adhesive flanges 1b supported by releasing strips 3 at the lower portion. The two releasing strips 3 are folded near the junction 2b between the upper and the lower portions of abbreviated condom to create two respective loose ends 3a that serve as pulling tags.
[0046] FIG. 9a: Perspective view of the abbreviated condom as in FIG. 9 duly deployed onto glans penis 5a. Deployment of the abbreviated condom thereof consists of expelling the air in the seminal receptacle 4a, placing the open end 4c of seminal receptacle 4a over the external urethral meatus 5b, and removing releasing strips 3 by pulling off their respective loose ends 3a. The exposed adhesive coating on the flanges 1b will, on smoothing against the distal end of penis, adhere to each other as well as glans penis 5a to form a leak proof seal. Note that said junctions 2b have now elongated and shifted into the said lower portion as the membranes 1a at said upper portion merge with flanges 1b to conform to the shape of glans penis 5a.
[0047] FIG. 10: Perspective view of another preferred embodiment of abbreviated condom. It is constructed by sealing two ultra thin flexile membranes in an omega or similar shape wherein the omega dome 6 contains the seminal receptacle 4a, and the omega base 6a together with two extended flanges 1b become the body of said abbreviated condom, thus resembling a configuration of a shortened non-rolled adhesive condom with opposing sides of the lateral wall being cut open as above mentioned. The internal surfaces of the flanges 1b are coated with adhesive 2 with the support of two releasing strips 3, both of which are folded near the omega base 6a with loose ends 3a serving as pulling tags for easy deployment of said abbreviated condom. The arrows denote the direction of pulling of loose ends 3a of releasing strips 3 during deployment. The open end 4c of the seminal receptacle 4a and its immediate surrounding area demarcated by adhesive margin 2a, which are adhesive free, are to be placed at external urethral meatus during deployment.
[0048] FIG. 10a: Perspective view of the abbreviated condom as in FIG. 10 duly deployed onto glans penis 5a. The air in the seminal receptacle 4a is expelled and with the removal of releasing strips 3 by pulling off the loose ends 3a, both flanges 1b are adhered onto glans penis 5a. The omega base 6a that connects the two flanges 1b thereof becomes part of the adhesive abbreviated condom. The adhesive-free open end 4c of the seminal receptacle 4a and its immediate adhesive-free surrounding area join up with external urethral meatus 5b to form a continuous passage for seminal fluid to be collected in the seminal receptacle 4a during ejaculation.
[0049] FIG. 11: Perspective view of an abbreviate condom prepared by folding. It comprises an elongated thin membrane, underpinned by a supporting film, which is coated with adhesive solely on its outer edges, with a releasing strip (backing membrane) disposed at each adhesive end of said membrane. Prior to deployment, the assembly is folded 8 with both releasing strips 3 partially pulled off towards each respective end to line 2b, where a portion of adhesive free area is still covered by releasing strip 3, to expose a segment of adhesive edges 1a near the fold 8 so that the edges 1a adhere to each other at folding, and thereby creating a seminal receptacle 4a. The folded configuration now resembles the abbreviated condom as shown in FIG. 9 ready for deployment. Note that the external supporting film(s) which are to be removed after deployment of said abbreviated condom are not shown in the figure.
