Isolating diseaseproof and contraceptive hygienic cover

An isolating diseaseproof and contraceptive hygienic cover including a cover body and a ring member. The cover body is substantially hoof-shaped and has an opening at a middle lower portion thereof. The ring member is coaxially fixedly connected to peripheral wall of the opening. The cover body has a wall radially extending from the opening and rearward inclined. The wall of the cover body has a thickness gradually reduced from the peripheral wall of the opening to outer edge of the cover body. The hygienic cover is sheet-like and has greatly reduced area and volume, so that the manufacturing cost and time thereof are decreased. In use, the present hygienic cover is able to provide more reliable contraceptive and diseaseproof effect and can be more conveniently and quickly put on/taken off in a-simple manner without affecting a sexual activity.

BACKGROUND OF THE INVENTION 
The present invention relates to a contraceptive and diseaseproof hygienic 
implement, and more particularly to an isolating diseaseproof 
contraceptive hygienic cover which prevents the peripheral portions around 
private parts or sexual organs of people from being infected due to skin 
contact in the process of sexual intercourse. 
In Chinese Utility Model No. 942249038, an isolating diseaseproof 
contraceptive hygienic pants disclosed, which includes a pants body and a 
separate contraceptive cap. The pants body is fixedly disposed with a 
fitting tube having a ring member, whereby the contraceptive cap can be 
fitted to the ring member to engage with the pants body. According to such 
arrangements, a user must first wear the pants body and then select a 
suitable contraceptive cap to fit with the pants body. While there are a 
number of disadvantages associated with such prior art, given as below: 
1. It is difficult in manufacture of such contraceptive implement, 
resulting in high cost of time and labor. 
2. It takes away the sensational thrills of sexual intercourse wearing such 
contraceptive. 
3. To put on such implement before sexual intercourse and take it off 
thereafter takes time, spoiling the moods of love making activities to 
most people in one aspect; the contraceptive cap is apt to separate from 
the pants body when suffering violent action force and fails to achieve 
the diseaseproof and contraceptive effects. 
Several other kinds of diseaseproof contraceptive implements are 
respectively disclosed in Chinese Utility Model No. 92230577.9, entitled 
"hygienic diseaseproof contraceptive pants", and No. 92227398.7, entitled 
"simple diseaseproof pants used in cooperation with phallus cap" and No. 
92208772.5, entitled "contraceptive and diseaseproof safety cap". Each of 
the above cited contraceptive implements is composed of a pants body or a 
so-called private parts protective film and a contraceptive cap which is 
integrally formed with the pants body or adhered thereto. Although such 
contraceptive implements are able to prevent the private parts from being 
contacted and infected during sexual intercourse. It is relatively 
inconvenient to make use of such implements. For example, the integrally 
formed pants and contraceptive cap must be worn simultaneously and 
continuously and once they are worn, in case the contraceptive cap does 
not suit the user, the cap can not be solely replaced. In addition, the 
pants body is apt to stick to a user's skin when put on or taken off, so 
the user can not easily put on/take off and comfortably wear such 
contraceptive implements. 
Furthermore, the aforesaid pants body has a unified thickness and is apt to 
be crimped in the process of use, rendering the user uncomfortable and 
resulting in the failure of diseaseproof and contraceptive effects. 
To simplify the above cited prior arts and make the users comfortable in 
wearing and to prevent users from being infected with either venereal 
diseases or particularly from being attacked by bugs hidden in pubic hairs 
of human being that can be transmitted during sexual intercourse, the 
present inventor designs an improved diseaseproof contraceptive. 
The present invention is safer than conventional condoms and is easier to 
put on or remove than pants-like contraceptive. The present invention has 
several advantages over a traditional condom in diseaseproof functions. 
The following situations can be effectively improved: 
1. It can prevent bugs of all kinds hidden in pubic hairs of human being 
from transmitting between each other. 
2. Venereal diseases caused by bacteria or viruses existing in the 
secretory liquid in female vagina or accumulated at the bottom end of a 
condom, still getting people infected, can be prevented. 
3. Taking off a condom after sexual intercourse carelessly can result in 
infection of venereal diseases even though it is very effective in 
contraceptive function. 
4. Infection of skin diseases of all kinds at the private parts of people 
can be prevented in the process of sexual intercourse. 
SUMMARY OF THE INVENTION 
It is therefore a primary object of the present invention to provide an 
isolating diseaseproof contraceptive hygienic cover which is manufactured 
at low cost and can be easily used while achieving reliable diseaseproof 
and contraceptive effect. 
It is a further object of the present invention to provide the above 
hygienic cover which includes a cover body and a ring member fixedly 
connected with the cover body and made of relatively stiff material 
whereby a contraceptive cap can be firmly fitted on the ring member 
without departing therefrom so as to ensure the diseaseproof and 
contraceptive effect. 
According to the above objects, the hygienic cover of the present invention 
includes a cover body and a ring member. The cover body is substantially 
hoof-shaped and has an opening at the middle lower portion thereof. The 
ring member is coaxially fixedly connected to peripheral wall of the 
opening. The cover body has a wall radially extending from the opening and 
rearward inclined. The wall of the cover body has a thickness gradually 
reduced from the peripheral wall of the opening to outer edge of the cover 
body. 
In a preferred embodiment, the width between two symmetric lateral arch 
edges of the cover body is equal to inguinals of human body. The upper 
arch portion of the cover body extends to a lower portion of human 
hypogastrium, while a lower portion of the cover body such downward 
extends as to cover or partially cover human scrotum. 
The cover body is made of resilient latex or foamed synthetic rubber 
material and the thickness of the wall of the cover body is reduced from 
the peripheral wall of the opening to the edge of the cover body, so that 
the cover body itself possesses a certain retaining strength and can keep 
standing upright without deforming even when suffering violent swinging 
force so as to achieve a reliable isolating effect. 
The hygienic cover of the present invention is sheet-like and has greatly 
reduced area and volume, so that the manufacturing cost and time thereof 
are decreased. In use, the present hygienic cover is able to provide more 
reliable contraceptive and diseaseproof effect and can be more 
conveniently and quickly put on/taken off in a simple manner without 
affecting sexual activity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Please refer to FIGS. 1 and 2. The contraceptive hygienic cover of the 
present invention includes a cover body 1 and a ring member 3. The cover 
body 1 is substantially hoof-shaped, having a wider upper end and a 
narrower lower end. That is, the cover body 1 has a tapered outline in 
general shape like an isosceles triangle having an acute included angle 
between the two equal sides, with well-rounded corners, and having 
indented equal sides. The cover body 1 is formed with an opening 6 at a 
middle or middle lower portion. The ring member 3 is integrally formed or 
fixedly connected to the peripheral wall of the opening 6. 
The width between two symmetric lateral arch edges of the cover body 1 is 
equal to or less than the distance between the corresponding points of the 
inguinals of the human body. The upper arch portion of the cover body 
extends to a lower portion of the hypogastrium of human body, while the 
lower portion of the cover body extends downward to cover or partially 
cover the scrotum of human body. 
The wall of the cover body 1 radially extends from the center of the 
opening 6 and is rearward inclined. 
Generally, the angle contained by the center line of the opening 6 and the 
wall is within 50-89 degrees. The thickness of the wall of the cover body 
1 is gradually reduced from the peripheral wall of the opening to the edge 
of the cover body 1. Therefore, the peripheral wall of the opening has a 
largest thickness within 8-2 millimeters, while the edge of the wall of 
the cover body has a smallest thickness within 2-0.01 millimeter. 
Alternatively, the thickness of the cover body can be substantially 
unified or slightly varied. 
The ring member 3 is coaxially fixedly connected to the peripheral wall of 
the opening of the cover body 1 and axially protrudes therefrom. As seen 
in FIG. 2, the ring member 3 includes a lip 4 which extends outwardly from 
the generally cylindrical outer surface of the ring member 3 at its 
outermost end. A cross section of the lip 4, taken on the plane A--A of 
FIG. 2, shows a generally triangular shape. Generally, the surface of the 
lip 4 facing the cover body 1 (the rear face, also referred to below as 
the vertical rear face) is a planar annulus, the inner surface is 
cylindrical, and the outer surface is conical. The facing surface and the 
inner surface are thus substantially at right angles along any cross 
section, like section A--A, which passes through the central axis of the 
ring member 3. The cross-section of the ring member 3 is right 
triangle-shaped or substantially right triangle-shaped and is made of 
relatively stiff material, whereby the contraceptive cap can be firmly 
fixed to the ring member without departing therefrom or falling off. The 
plane in which the vertical rear face of the ring member 3 resides is 
spaced from the plane of the opening 6 of the cover body 1 by a distance 
within 5-20 millimeters. 
The cover body 1 further has an arch convex portion 5 at the lower portion 
corresponding to the scrotum of human body, whereby when using the cover 
body 1, the convex portion 5 thereof can suitably receive the scrotum. 
The dimension and shape of the above isolating contraceptive cover are 
determined according to the statistic data of related portions of human 
body. Several preferred specifications of the contraceptive covers can be 
manufactured to suit various users and achieve a comfortable feeling. The 
user can easily quickly put on the cover body without trouble. In 
addition, because the cover body is made of resilient latex film or foamed 
synthetic rubber material and the thickness of the wall of the cover body 
is reduced from the peripheral wall of the opening to the edge of the 
cover body, the cover body itself possesses a certain retaining strength 
and can keep standing upright without deforming. Furthermore, by means of 
the resilience of the latex and rubber material, the cover body is always 
adapted to the profile of the related portions of human body so as to 
effectively isolate and protect the same from being contacted and 
infected. Moreover, the cover body serves to buffer external force exerted 
on the scrotum or testes so as to protect the same. 
The present invention has the following advantages over the prior arts: 
1. It can guard a person against various kinds of venereal diseases. 
2. It can prevent a condom from disengagement in the process of sexual 
intercourse. 
3. It can prevent a person from being infected when removing a condom from 
the body. 
4. It can get people relieved from a psychological burden of being infected 
by venereal diseases and help people fully enjoy the sentions of sexual 
intercourse. 
5. It has two separate portions and condoms of various sizes can be 
selectively secured firmly to the ring member 3. 
The above embodiment is only an example of the present invention and the 
scope of the present invention should not be limited to the example. Any 
modification or variation derived from the example should fall within the 
scope of the present invention.
