Abstract

<P>PROBLEM TO BE SOLVED: To solve problems of a conventional condom wherein there is a risk of sperm leaking out into vagina as a gap is formed between a penis and the condom when the penis atrophies after ejaculation, and wherein there is a risk of the condom being left inside the vagina when the atrophied penis is taken out of the vagina. <P>SOLUTION: The condom comprises a sperm storage part 2 at the distal end, a tubular part 3 capable of covering most of the length of the penis in the intermediate part, and an opening part 4 for insertion at the proximal end. Since an adhesive layer 5 to adhere to the outer surface of the penis 10 is attached at an appropriate location on the inner surface of the tubular part 3 of the condom, the condom can be securely positioned and held to the penis even when the penis atrophies, and the gap between the penis and the condom can be securely sealed with the adhesive layer 6 part. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a condom used by being attached to a male penis during sexual intercourse, and more particularly to an improved condom that can be prevented from falling off (dropping out) from the penis when attached to the penis.

  Condoms are the most popular device for contraception during sexual intercourse and for preventing sexually transmitted diseases. In addition, several types of condoms of this type are commercially available, and a condom of an appropriate size can be selected according to the size (thickness) at the time of penis erection. The size of the condom is selected based on the size (thickness) of the person's penis erection, and the condom can be mounted in a relatively fitted state in the penis erection state.

  By the way, after ejaculation from the erection state, the penis rapidly shrinks and becomes small (thin), and the condom that fits at the time of erection begins to rub against the penis at the time of penile atrophy. If the penis shrinks with the condom attached in this way and the condom is doubled, a gap is formed between the penis and the condom, and the ejaculated semen may leak into the woman's vagina (female On the other hand, if there is a pathogen in the vagina, there is a risk that the penis will have a sexually transmitted disease.

  Also, after ejaculation in the condom with the vagina inserted, if the penis shrinks and the condom is ducked, the condom often comes off the penis and remains in the vagina when the penis is extracted from the vagina. In that case, taking out the condom remaining in the vagina is troublesome, and semen in the condom may leak into the vagina.

  By the way, in order to prevent the condom from falling off (remaining in the vagina) from the penis after ejaculation as described above, there are conventionally known condoms provided with various dropping prevention means.

  For example, Japanese Patent Laid-Open No. 2000-83984 (Patent Document 1) discloses a condom in which the outer peripheral surface near the opening of the condom cylindrical portion can be tightened with a band-shaped fastener. Japanese Patent Laying-Open No. 2006-280622 (Patent Document 2) discloses a condom that has a bag shape that can cover only the vicinity of the head of the penis and that has an opening peripheral portion tied with a string. Yes. Further, Japanese Patent Application Laid-Open No. 2005-312849 (Patent Document 3) discloses a condom in which a stretchable mooring string for mooring (hooking) a testicle with the condom attached to the penis is attached to the opening edge of the condom. Is disclosed.

  However, the condoms of the above-mentioned patent documents have the following problems.

  First, in each condom of Patent Document 1 and Patent Document 2, it is necessary to bind the outer periphery of the condom with a fastener or a string after the condom is mounted on the penis. It gets very bad. In addition, if the penis contracts after ejaculation in the attached state, the above-mentioned fastener or string may not function sufficiently (the binding function will be lost), and the condom will come off when the penis is removed from the vagina. There is a risk of remaining.

  Moreover, in the condom of the said patent document 3, since a mooring string which can be expanded and contracted is used by being hooked on the testicle, the testicle is pulled by the mooring string, and the wearing feeling becomes very worse, and the penis atrophy after ejaculation. When this happens, the mooring string may come off the testicles, and the adverse effects caused by the condom being doubled (making a gap between the penis and the condom) cannot be eliminated.

  Therefore, the present invention has a simple configuration, can be easily mounted, has no sense of incongruity, and can reliably prevent semen leakage and dropout even if the penis contracts after ejaculation. It was made for the purpose of providing a condom.

  The present invention has the following configuration as means for solving the above problems.

  The present invention is directed to a condom having a semen reservoir at the distal end, a cylindrical portion capable of covering most of the penis length at the middle, and an insertion opening at the proximal end.

  The condom of the present application is formed into a thin film bag shape using a general elastic material such as latex, silicon, or polyurethane resin. In addition, the opening part of the condom is provided with a ring part having a small diameter.

  And the condom of this application is characterized by adhering the adhesive layer which can adhere to the outer peripheral surface of a penis in the inner surface appropriate place of the cylindrical part.

  The pressure-sensitive adhesive layer is preferably provided at an appropriate position near the opening on the inner surface of the cylindrical portion. The pressure-sensitive adhesive layer is preferably attached in an annular shape having a predetermined width (for example, but not limited to 5 to 20 mm) over the entire circumference of the inner circumferential surface of the cylindrical portion. It may be attached in the form of spots with small intervals around the circumference. The formation place of this adhesive layer may be one place or a plurality of places in the length direction of the cylindrical portion. The pressure-sensitive adhesive layer may also be applied annularly to the inner surface at a position corresponding to the outer peripheral surface of the penis glans near the tip of the cylindrical portion.

  As the material of the pressure-sensitive adhesive layer, for example, a rubber-based pressure-sensitive adhesive, an acrylic pressure-sensitive adhesive, a silicon pressure-sensitive adhesive or the like that does not adversely affect the skin is employed. The adhesive strength of the pressure-sensitive adhesive layer is such that it can be appropriately adhered to the penis skin surface. In addition, the thickness of this adhesive layer may be a film-like ultrathin.

  In addition, the condom is wrapped in an annular shape outward from the peripheral edge of the opening and wrapped in a flat state. At that time, the adhesive layer is in contact with the outer surface of the cylindrical portion of the condom, so that the adhesive layer faces A coating (for example, a release treatment agent such as a silicon-based resin or a fluorine-based resin) to which the pressure-sensitive adhesive layer hardly adheres is preferably applied (or pasted) to the outer surface of the cylindrical portion in the vicinity.

  The condom of the present application functions as follows. First, when this condom is normally put on an erect penis, the adhesive layer on the inner surface of the cylindrical part adheres to the outer peripheral surface of the penis, and the entire condom is securely held in a normal position with respect to the penis (moving) do not do). Therefore, even if a penis with a condom is inserted into the vagina and moved back and forth, the condom will not be displaced in the state where it is covered with the normal position of the penis. It is securely sealed.

  After ejaculation, the penis rapidly shrinks (smaller and thinner), but the adhesive layer part remains adhered to the outer peripheral surface of the penis, so even if the penis becomes thinner, the adhesive layer part of the condom Is reduced in diameter. Therefore, since the sealing function in the pressure-sensitive adhesive layer portion is not attenuated, semen ejaculated in the condom does not leak to the outside (in the vagina). Further, when the dwarfed penis is extracted from the vagina, the condom can be reliably extracted together with the penis because the adhesive layer remains adhered to the outer peripheral surface of the penis. The used condom may be extracted from the vagina with the penis and then removed from the penis.

  As described above, according to the condom of the present invention, the pressure-sensitive adhesive layer is attached to an appropriate position on the inner peripheral surface of the cylindrical portion. Therefore, when this condom is attached to the penis, the pressure-sensitive adhesive layer portion adheres to the outer peripheral surface of the penis. In addition, the condom can be reliably held in a state where it is covered with the normal position of the penis, and the penis and the condom can be sealed with the adhesive layer portion. In addition, even if the penis atrophy after ejaculation, the adhesive layer part remains adhered to the outer peripheral surface of the dwarf penis, so the semen ejaculated in the condom remains sealed before the adhesive layer part. It becomes.

  Therefore, the condom of the present application has a simple structure of attaching the adhesive layer to the inner peripheral surface of the cylindrical portion, so that the mounting work is not troublesome (generally it can be mounted in the same manner as the condom), and the feeling of use (sexuality) is There is an effect that the function as a condom (the function of blocking the penis and the vagina and the function of preventing semen leakage) can be reliably achieved without lowering.

  Hereinafter, the condom of the present embodiment will be described with reference to FIGS. 1 to 3. FIG. 1 shows a condom wearing state in which the penis 10 is in an erection state, and FIG. The state is shown, and FIG. 3 shows a form of the condom 1 during packaging.

  The condom 1 of this embodiment has an elongate portion having a semen reservoir 2 at the distal end, a cylindrical portion 3 that can cover most of the length of the penis at an intermediate portion, and an insertion opening 4 at the proximal end. It is formed into a thin film bag shape. A ring portion 5 having a small diameter is provided in the opening 4 of the condom 1.

  As a material for the condom 1, for example, a general-purpose material having elasticity such as latex, silicon, or polyurethane resin can be used.

  Further, the condom 1 has an adhesive layer 6 that adheres to the outer peripheral surface of the penis 10 at a suitable position on the inner surface of the cylindrical portion 3. The pressure-sensitive adhesive layer 6 is formed in an annular shape having a predetermined width W (for example, W = 5 to 20 mm width) over the entire circumference of the inner peripheral surface of the cylindrical portion 3 at a position near the opening 4 on the inner surface of the cylindrical portion 3. It is attached. The place where the pressure-sensitive adhesive layer 6 is formed may be one place or a plurality of places in the length direction of the tubular portion 3. This pressure-sensitive adhesive layer may also be applied annularly to the inner surface of the position corresponding to the outer peripheral surface of the penis glans near the tip of the cylindrical portion 3 (the reason will be described later).

  As the material of the pressure-sensitive adhesive layer 6, for example, a rubber-based pressure-sensitive adhesive, an acrylic pressure-sensitive adhesive, a silicon-based pressure-sensitive adhesive or the like that does not adversely affect the skin is employed. Moreover, the adhesive force of this adhesive layer 6 should just be a grade which adheres moderately with respect to a penis skin surface. In the illustrated examples of FIGS. 1 and 2, the thickness of the pressure-sensitive adhesive layer 6 is displayed as a considerable thickness in the drawing, but actually the thickness of the pressure-sensitive adhesive layer 6 is a film-like electrode. It is thin.

  By the way, this condom 1 is formed into a flat state by being wound outwardly from the ring portion 5 at the peripheral edge of the opening as shown in FIG. 3, but at this time, the adhesive layer 6 is formed into a condom cylindrical portion. In order to contact the outer surface 3, it is preferable to apply a film in which the pressure-sensitive adhesive layer 6 is difficult to adhere to the outer surface of the cylindrical portion (range L in FIG. 1) near the pressure-sensitive adhesive layer 6. As this film, for example, a release treatment agent such as a silicon resin or a fluorine resin can be used.

  The condom 1 of this embodiment functions as follows. The condom 1 is attached in the state shown in FIG. 3 while the center part is applied to the tip of the penis glans head and then the part to be wound is rewound along the outer surface of the penis. If a release treatment agent is applied to the outer surface of the corresponding cylindrical portion, the pressure-sensitive adhesive layer 6 portion can be rewound without difficulty.

  As shown in FIG. 1, when the condom 1 is normally covered with the penis 10 in an erected state, the adhesive layer 6 on the inner surface of the cylindrical portion 3 adheres to the outer peripheral surface of the penis 10, and the entire condom 1 is 10 is reliably held at the normal position. Therefore, even if the penis 10 with the condom 1 is inserted into the vagina and moved back and forth, the condom 1 is not displaced in the state where the penis 10 is covered with the normal position of the penis 10, and the penis 10, the condom 1 and Is securely sealed by the adhesive layer 6 portion.

  In addition, when the adhesive layer is applied to the portion near the tip of the cylindrical portion 3 (the portion corresponding to the outer peripheral surface of the penis glans head), the portion close to the tip of the cylindrical portion 3 is applied thereto in the mounted state. The adhesive layer is adhered to the outer peripheral surface of the penis glans head. Therefore, even if it is moved back and forth while inserted into the vagina, the portion near the tip of the condom 1 does not rub against the penis glans head. In addition, when an adhesive layer is also applied annularly on the inner surface near the tip of the cylindrical portion 3 in this way, prostate fluid secreted from the urethral orifice before ejaculation (lubricating) wraps around between the penis and the condom. As a result, slippage between the penis and the condom due to the secreted prostate fluid can be prevented. If the penis and the condom do not slide, it can be expected to prevent the condom from being broken by rubbing between the penis and the condom.

  After ejaculation, the penis 10 rapidly shrinks (smaller and thinner) as shown in FIG. 2, but the penis 10 is small because the adhesive layer 6 portion remains adhered to the outer peripheral surface of the penis. Even if it becomes (thinner), the pressure-sensitive adhesive layer 6 portion follows and is reduced in diameter. Therefore, since the sealing function in the adhesive layer 6 portion does not attenuate, the semen 7 ejaculated in the condom 1 does not leak out to the outside (in the vagina). Further, when the dwarfed penis 10 is extracted from the vagina, the condom 1 can be reliably extracted together with the penis 10 because the adhesive layer 6 remains adhered to the outer peripheral surface of the penis. The used condom 1 may be removed from the penis 10 after being extracted from the vagina together with the penis 10.

  Thus, in the condom 1 of this embodiment, when attached to the penis 10 as shown in FIG. 1, the adhesive layer 6 part adheres to the outer peripheral surface of the penis, and the condom 1 is put on the normal position of the penis 10. The position of the penis 10 and the condom 1 can be sealed with the adhesive layer 6 portion. Further, as shown in FIG. 2, even if the penis 10 is shrunken after ejaculation, the adhesive layer 6 portion remains adhered to the outer peripheral surface of the shrunken penis 10, so that the ejaculated semen 7 in the condom 1 is obtained. It remains sealed before the pressure-sensitive adhesive layer 6 portion.

  Therefore, the condom 1 has a simple configuration in which the pressure-sensitive adhesive layer 6 is attached to the inner peripheral surface of the cylindrical portion, so that the mounting operation is not troublesome (generally, it can be mounted in the same manner as the condom), and the feeling of use (sexuality). The function as a condom (blocking function between penis and vagina, and function of preventing semen leakage) can be reliably achieved.

It is a wearing figure in the penis erection state in the condom of this-application Example. It is a change figure from the state of FIG. 1 (mounting figure in penis atrophy state). It is a form figure at the time of packaging of the condom of FIG.
