Complete Specification for the invention entitled: Modified Condom mesiA(following statement is a full description this invention, including the best method of performing it known The description is to be typed in double spacing, pica type fade in an area not exceeding 250 mm in depth and 160 mm in width, T W on tough white paper of good quality and it is to be inserted inside this form.

10/6-LC.J. Tttio~ir commonwealth Government Printer Canberra 1 MODIFIED CONDOM The said invention relates to condoms also called contraceptive sheaths.

The unique design of the said invention has been devised to provide an extra measure of effectiveness against conception and to overcome disadvantages in the prior art of condoms.

Contraceptive devices, such as condoms, being sheaths for, the insertion of the male sex organ, have long been used as a means of preventing conception.

Condoms are sheatlis typically made oi latex rubber, are generally tubular, having an inside surface and an outside surface and having a closed end and an open end.

It is the open end into which the penis is inerted P L o*e o 15 v while the closed end forms a nipple wherein semen is .o deposited after ejaculation.

o o. They may also incorporate the use of lubricants and 0 spermicides.

Contraception is achieved by the entrapment of sperm 20 within these sheaths thus preventing fertilization from occuring.

The said invention differs from the above description of conventional condoms by reason of its' actual design and I *superior performance.

25 The desgn features are hereafter detailed and: the /0 i4Z advantages of that design explained.

It has long been a problem of conventional condoms that they fail to prevent conception. 4 This can happen if the conventional condom is ±e4-~fi±t- d P~ A 30 If not fitted properly it has a tendancy to roll up during use and may come off the penis.

Also, if an erection is not maintsined whilst the penis is within the vagina, the same outcome may occur.

A more secure attachment is therefore required to overcome this problem.

-r V 0 T rr i i- rr 00 00 0 000 0000 000 0 Q 0 0 0 0 0 0 0 0 0 0 0 00 0 000 0 000:005 0*0 0 t t4 00 *04 -2- In the search for the most secure attachment possible even the use of adhesives has been put forward to be incorporated with the use of condoms.

However this concept is undesirable and unnecessary in its' application.

The superior design of the said invention makes use of the forces present in relation to itself and its' use that substantially overcomes the problem of insecure attachment found in the prior art of condoms.

The said invention is designed to enclose only the glans of the penis.

It grips the penis immediately below the ridge of the glans which is an area that provides greater resistance to dislodgement than at the base of the penis where a 15 conventional condom is attached.

This greater resistance is achieved in relation to the differing diameters of the glans and shaft of the penis and the forces applied by the said invention thereon.

The said invention has a small expandable open end which has a thickened rim incorporating a channel in its' inside surface designed to provide extra grip of the said invention to the penis.

This channel is wedge shaped at its' top becoming trdghed towards its' bottom and runs the entire length of 6 25 the inside surface of the openings' rim. Vhs For evd' i s-a 4J is erection of the penis occurs, the channel is stretched C'"O' to clamp down onto the penis. 5 0? Forward and backward thrusting forces also present on the said invention during copulation cause the channel to be 30 pulled open and closed. That is, to the extent that the stretching factor already acting upon the channel will allow; thus forcing the channel to bite more and more deeply onto the penile tissue.

These factors operating on the channel also tend to cause a suction to develop as penile tissue forces air out of the channel.

001l 3 Thus the said invention sustantially overcomes the problem of dislodgement found in conventional condoms.

Failure of conventional condoms to prevent conception frequently results from the rupture of the thin wall of the sheath,usually at the tip which is subjected to stresses such as stretching.

This stretching is related to the area covered by the conventional condom and the movement of the glans and shaft of the penis within it.

As the said invention covers a much smaller area and that area being only the glans of the penis; stretch factors are greatly reduced as is stretching and the risk of rupture.

The said invention is thus much less likely to rupture 15 than is a conventional condom.

Other disadvantages of conventional condoms are less extreme but are nevertheless significant in the appeal of its' use as a means of contraception.

The user of a conventional condom preferabley needs to 20 have an erection before putting it on.

However the said invention can be easily applied to a flacid penis.

The user is able to stretch the opening of the said invention into which he inserts his penis then releases it to grip immediately below the ridge of the glans of the penis.

The tter movement of the foreskin is not impeded and can roll up over the said invention after fitting.

As a conventional condom blankets the entire penis, there is no direct physical contact between the male and

P

female organs and the user exeriences a loss of sensitivity.

The said invention covers only the glans of the penis thus exposing the rest of the penis to normal stimulation.

Hence the senujitivity experienced is much greater than that obtained with a conventional condom.

i 1LI 4 While the said invention is susceptible of embodiment in many different forms, there is shown in the drawing and will herein be discribed in detail one specific embodiment, with the understanding that the present disclosure is to be concidered as an exemplification of the principles of the said invention and is not intended to limit the said invention to the embodiment illustrated.

Fig. 3 is an exploded cross section of the rim and opening of the same only.

The said invention shown in Fig. 1 -1 shows the outside surface which is a tubular envelope made of latex rubber material. Fig.l-2 shows the closed end which forms a nipple wherein semen is collected. Fig.l-3 shows the open end wherein the penis is inserted.

Fig.2-1 shows the inside surface. Fig.2-2 shows the inside area of the semenal nipple. Fig.2-3 shows the thickened rim of the opening. Fig.2-4 shos the opening itself. Fig.2-5 shcfs the channel which is wedge shaped P0 R4 15 at its' top and becomes troughed at its' bottom. The channel is shown to be situatedin the inside area of fS 43 th e rim andyrun around its' entire length. PS Fig. 3-1 shows the opening. Fig.3-2 shows in close up/ a profile the channel an its' shape which is wedged at 20 the top becoming troughed at its' bottom.

As the said invention is made of latex rubber material, this channel can be stretchsd an flexed in and out enabling it to perform as herebefore described in relation to its' attachement to the penis.
