Detailed Description of the Invention

[0001]

[Field of the Invention]

The present invention relates to a male genital sheath, and more particularly to a male genital sheath having means for physically stimulating a partner during intercourse. The present invention also relates to a prophylactic male genital sheath having means for physically stimulating the partner during intercourse.

[0002]

BACKGROUND OF THE INVENTION

Harmony, pleasure and joy in sex play an important role in the satisfaction of a couple. However, because of race, growth, heredity, or other factors, the reproductive organs of a man's population may achieve the desired physical stimuli needed by the other person to obtain such pleasure and joy. It does not have a suitable transverse thickness or circumference. On the other hand, such shortcomings are tightened due to a large transverse gap or overgrowth in the vagina of the other person due to the other person, for example due to race, heredity, or other congenital factors, or elongation resulting from childbirth. Due to no vagina. Sometimes the drawback may be the result of a combination of the above factors.

To alleviate the despair and misery associated with such shortcomings, by producing a greater physical stimulation or arousal during sexual intercourse by significantly expanding the effective transverse extent or circumference of the male genitals. There are many available appliances (commonly known as "sexual aids") designed to be worn by a man in order to be able to. Sexual aids fall into two general types: substantially rigid "armour" types and "thin flexible" types. The armor type allows the user to wear a relatively rigid structure. Due to the rigidity of the structure, physical stimulation or excitement to the opponent is likely to be achieved with good certainty. However, while armor-type aids do not offer a reasonable solution to the deficiencies due to incompatibility of genital size, those who wear aids are not They are substantially shielded by a hard and usually thick accessory so that they cannot enjoy pleasure and excitement. A typical example of a thin flexible type is a condom in which a contoured texture is distributed on the contact surface. With this type of aid,
The person wearing the aid is sensitive because the condom is typically made of a very thin elastomeric material. However, due to the condom's unique requirements, which are somewhat related to the method of making the condom, the shape of the protruding tissue is 0.03
Limited to, and equivalent to, the thickness of a condom that is as thin as mm. Such aids provide only a very limited amount of physical irritation to the person wearing the aid and produce pleasure and irritation for those with relatively serious problems of the type described above. May not be appropriate for you. Therefore, it is desirable for a condom-assisted device having a very thin body to be provided with physically protruding stimulation means to achieve the desired physical stimulation. On the other hand, it is known that condom-like aids with physically protruding stimulation means are easily and quickly captured and removed by the sexual organs of the partner during intercourse. Therefore, it is desirable that the improved assisting device having a physically distinctive feature is provided with a means for preventing easiness of displacement. In addition, it is highly desirable that such improved aids provide complementary preventive functions as well as desirable physical irritation.

[0004]

[Object of the Invention]

Therefore, it is an object of the present invention to have a very thin main body to accept male genitals and to physically stimulate the opponent to be in a position to enjoy sexual pleasure, joy and excitement. An object is to provide an improved male genital sheath having prominent features. It is also an object of the present invention to provide an improved aid of the above character which has means for preventing the aid from slipping away from the male genitalia wearing the aid. Moreover, it is also an object of the present invention to provide the general public with a useful selection of male genital sheaths with physical stimulation means for sexual life.

Detailed Description of the Preferred Embodiments

Embodiments of the present invention will now be described by way of example with reference to the accompanying drawings. 1-4B, there is shown an embodiment of a male genital sheath of the present invention. As shown, the sheath 1 includes a main body 11, a closed tip with a semen receiving portion 12, and an open end 13 with a first collar member 14. The sheath 1 is capable of providing an acceptable level of tactile stimulus to the wearer and is highly durable, such as natural rubber latex, polyurethane or other synthetic elastomeric material, so that the sheath may remain stretched and taut during intercourse. It is preferably made of a very thin and strong elastomeric material. Latex membranes 15 having a thickness of 0.02 mm to 0.12 mm are known to be used in prophylactic condoms that provide high sensitivity without significant safety trade-offs.

The sheath is made by traditional methods of manufacturing prophylactic condoms using “dip” or “dip and dry” techniques. Thus, in this method, a penis-shaped mandrel (not shown) made of, for example, glass, ceramic or metal is immersed in a bath of elastomeric material. A bulbous extension is formed at the lower tip of the mandrel to form the semen receptacle 12. The first collar member 14 is formed by rolling the open end of the latex coating toward the bulbous tip until a collar of a predetermined thickness is formed. The latex coating is then dried or cured at elevated temperature to have a predetermined thickness of a substantially solid flexible collar and a latex film thickness of as much as 0.02 mm using modern technology. Main body part 11
And a finished sheath with a semen receiver 12. In use, the first collar member 14 is preferably inserted inside the genitals of the person who is wearing the sheath, after the forward movement of the penis.

Although the thickness (d) of the first collar member 14 varies with the length of the latex coating that is rolled up, the preferred range of thicknesses is to accommodate different incompatible couples of the genitals. In the area of 2 to 5 mm. In most circumstances, a thickness of 3 mm is considered adequate, but a collar thickness of 1 mm produces discernible results for couples with less serious problems.

The preferred effective length (L) of the sheath, ie, the distance between the tip of the sheath and the base of the collar, is 4 to 4 in contrast to typical lengths of conventional condoms, which are usually greater than 17 cm. It is preferably 10 cm. Such a short length is chosen because it is preferably inserted into the first collar member or the mating genitals during use. In order to improve the compression grip of the first collar member 14 on the penis 20 and to minimize undesired or premature displacement during coitus.
Is made smaller than the opening (ψ) in the main sheath body by reducing the diameter of the penile mandrel at a distance or position from the tip, corresponding to the first base, for example. In order to improve the overall grip of the sheath, the main body 11 is designed so that in use the main body is a close fit on the penis.

Referring to FIGS. 4A and 4B, which show a sheath in normal use, the sheath is inserted into the penis prior to intercourse when penis 20 is in an erected state. When the sheath is properly applied, the first collar member 14 may allow the user to position the collar member closer to or further away from the free end 22 of the penis, but the middle portion of the penis 20. It is preferably located close to. Since the thickness of the first collar member increases the effective perimeter of the penis at the location of the collar 14, the opponent
It is likely that they will enjoy the additional pleasure and excitement that greatly arises from physical stimulation.
In addition, compression of the penis 20 by the first collar member 14 helps slow backflow of blood from the erected penis, thereby prolonging erection and prolonging sexual pleasure and pleasure.

In order to prevent the sheath 1 from prematurely disengaging from the penis 20 due to normal reciprocating motion during sexual intercourse, it is highly preferred to wear a preventive condom on top of the sheath 1 in addition to it. In addition to providing extra protection against pregnancy and sexually transmitted disease, the additional condom 4 can also provide extra benefits. First
In particular, if the condom 4 has a close compressible penis envelope, the compression tension helps keep the collar in place and helps reduce the chance of premature slippage. Secondly, the overlap of the condom envelope around the collar member smoothes and provides cushioning for the abrupt transition between the main body of the sheath and the collar, thereby reducing the risk of injury to the opponent. Third, the condom helps to retrieve the sheath and prevents it from coming off if the sheath is actually displaced from the penis. This is especially useful when the penis becomes sluggish during intercourse.

Referring now to FIGS. 5A and 5B, there is shown a sheath 1 of the present invention in combination with a first aspect restrictor, which in this embodiment is a second in the form of a compression ring 50. It is composed of a collar member 50. As shown, the compression ring 50 is the tip 1 of the sheath.
2 and the first collar member 14, and the twelfth collar member 14
Located near the base of the.

The compression ring 50 (ie, the second collar member) is made of an elastomeric material having a thickness that is significantly less than the thickness of the first collar member 14 for the following reasons. Preferably, the elastomeric second collar member 50 is made with an inner circumference that is less than the circumference of the erected penis, so that additional grip on the sheath is made to further reduce the risk of premature slippage. You can In addition, the second collar member also provides an additional synergistic effect. Referring to FIGS. 6 and 7A, a sheath is shown in combination with a compression ring 50 on an erect penis 20. Referring to FIG. 7B, the penis
It is shown pulled out of the vagina as part of the reciprocating motion associated with sexual intercourse. During withdrawal, the contact pressure between the vagina (not shown) and the penis 20 causes the first collar member 14
Tend to be pushed toward the head 22 of the penis 20. However, the second
This contact pressure causes the first collar member to be carried over the ring 50 for the other collar member 50. At the moment of being carried, the effective perimeter or transverse thickness of the penis increases instantaneously, thereby producing extraordinary physical irritation and excitement. The first collar member 14 to be used in this embodiment may have less compression so that it is more easily carried around the second collar ring, which is the compression ring 50. Next, penis 20
When the invades into the vagina, the first collar member 14 is returned to its original position as shown in FIG. 7A. A conventional prophylactic condom 4 may be worn over the sheath and ring combination to obtain similar benefits as described above.

Instead of using a separate outer ring 50 as the second collar member, the second collar member 50 may be formed integrally with the sheath. This can be done by first forming a sheath with a collar of small thickness by the method of making a condom described above. After formation of the collar of relatively small thickness (which becomes the second collar member), the mandrel is re-immersed in the latex bath and the latex coating is rolled up and immediately adjacent to and immediately above the compression ring, the thick first collar. The member can be formed.

Referring to FIGS. 8A, 8B and 9, there is shown the sheath 1 described above in combination with a second collar member 60 or restriction of the second embodiment. The restrictor 60 includes a compression ring 62 and a plurality of tongue members 64 extend from the ring member 60. The tongue is provided to enhance the retention of the ring and is preferably made of a thin flexible material and the side of the tongue facing the penis in use is coated with adhesive. During use, the tongue is fully extended and the adhesive surface is applied to the penis, holding the ring in place in addition to or instead of the inherent compressive force of the elastomeric ring. In addition, the tongues are used as a means for adjusting the inner clearance of the ring members, which enhances compression retention by wrapping the tongues around the ring as shown in Figure 8B.

Referring to FIGS. 10A-11B, there is shown the sheath 1 described above in combination with the second collar of the restrictor of the third embodiment. The third embodiment 70 includes a ring 72 similar to the ring described above, and a plurality of strap members 76 allows the second compression ring 7 to be included.
4 is connected. In use, the ring 72 is inserted over the sheath at its proximal location with the phosphor imaging region at the base of the collar member 13. The other ring 74 is inserted at the distal end of the penis and the sheath is usually held firmly in place. Similar to the second embodiment, the strap member can be tightened in a manner as shown in FIG.
Wrapped around the ring. As a modified example, the ring 72 of the third embodiment is shown in FIG.
As shown in B, it may be put in the sheath immediately near the base of the collar member 13. Obviously, the restrictor of the embodiment may be formed integrally with the sheath or may be formed separately.

While the preferred embodiment of the invention has been described for purposes of illustration, various modifications, additions, variations and permutations are possible without departing from the scope and spirit of the invention described herein. As will be understood by. Although the present invention has been described primarily with regard to enhancing physical pleasure and irritation during intercourse, the design of the sheath has certain demanding aspects for the design of the sheath and the use of an impermeable latex membrane. You will notice.

It should be understood that the features of the invention, which have been described in separate embodiments for clarity, may be combined in a single embodiment. On the contrary, the features described in a single embodiment may be provided separately or in any suitable subcombination.
