Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condom worn by a woman, and secures a natural feeling without impairing feeling at the time of wearing, thereby improving safety regarding contraception. The present invention provides a female-worn condom that is easy to use and enhances the effect of preventing contact communicable diseases. 2. Description of the Related Art A conventional condom worn by a woman is provided with a ring formed of a hard elastic material along a cut surface of an opening of a bag made of a thin film of synthetic resin, and the elastic material is provided inside the bag. It has a molded ring for fixing the inside of the vagina, and is made of a thicker material with poor elasticity compared to a general male condom. The above-mentioned material is a characteristic required to maintain a certain strength in a fixing method using a ring, and there is an unnatural feeling of use due to poor elasticity and thickness. In addition, the formation of a large ring for reinforcement and prevention of depression at the opening of the bag body around the penis insertion opening is caused by accidental insertion of the penis out of the condom or in the use of the condom in the vagina during use. Although it is a shape required to avoid being pushed, the above-mentioned ring portion is exposed outside the vagina and hangs, and there is a feeling of foreign matter, which significantly impairs emotion.

-19454, k Japanese Patent Application Laid-Open No. 10-243965. [0006] The application cited herein does not mention the relationship between the shape and material of the condom and the feeling of use.
If the material defined by the shape and the thickness of the material are stiff or thick, the feeling of use is unnatural and uncomfortable. [0007] One of the features of these applications which are different from conventional women's wear condoms which are generally commercially available is in the method of wearing, and the condom is attached to pants made of A, non-woven fabric or rubber. Thing, B, string
A band that is tied to the thigh or waist and fixed, C,
The part of the condom exposed to the outside from the vagina is spread to form an adhesive piece, which is then fixed with an adhesive or the like. In the female condom having the above-mentioned adhesive strip, it is necessary to join it to another material in order to stabilize the shape of the adhesive strip. In the case of integral molding, it is necessary to give the material a certain degree of hardness or to mold the part to which the adhesive is applied to be considerably thick, and since the adhesive piece is stuck to the body, there is a problem in the usability. Since the work of applying the lubricant and the work of gluing and pasting of release paper overlap, it is hard to say that this is a reasonable method. Sticking to the abdomen and buttocks is also troublesome. In the fixing method using a band or a string, it is difficult to keep the direction of pulling outward from the vaginal opening uniformly at 360 degrees, and bias tends to occur. Also, since a force is applied to the joint between the string or band and the condom, the material should have a certain degree of hardness, the part to be joined to the string or band should be formed quite thick, or part of it should be made of another material. It needs to be replaced. There is also a problem with the position fixing ability during use. In the method of attaching the pants, the size of the pants varies greatly from person to person, so that it is necessary to prepare a plurality of sizes, and it is costly to produce the pants themselves.
Moreover, it is the same as the act of wearing the pants, which raises the question of the feeling of use. It is unlikely that it is possible to sufficiently cope with the difference in the position of the vaginal opening depending on the body type of the wearer. The position of the vaginal opening varies depending on the body type of the wearer, but there is no mention of this. If the pants are made of rubber, the size is flexible, but if the pants have a general shape, the cost increases. Further, it is the same as the cloth pants in that it cannot cope with the difference in the position of the vagina depending on the body shape. [0015] There are rubber pants with condoms attached, but no condoms have been stretched so much that they can be worn. Stretching the condom so that it can be worn saves manufacturing costs and makes it possible to create a female-worn condom with excellent usability. Although the above problem can be solved by using small pants that are integrally formed with the condom, the application can be made, but no application has been made assuming that the pants should be worn greatly extended. In order to stretch, the material must have great elasticity. That is, a large elasticity is given to the cylindrical body inserted into the vagina. In the case where the tubular body is a thin film having large elasticity, the tubular body sticks to the penis during intercourse, and the tubular body moves in the vagina while expanding and contracting with the insertion movement. It is no different from the feeling of using a condom. Also,
There is also a risk of breakage with exercise. In a female-worn condom, how to reduce the thickness, how to maintain the strength of the material by reducing the thickness, and prevent the condom from shifting in the vagina when the thickness is reduced There is no mention of how to keep the shape from deforming. [0019] At the time of mounting, there is no foreign matter around the penis insertion port, and a tactile sensation as close to natural as possible using a thin and flexible material that is rich in elasticity is used. Feeling) and maintaining the shape of the woman's body, and ensuring the safety of contraception even if the penis is inserted without confirming the condom insertion port visually or tactually,
To provide an easy-to-use female-worn condom that covers the local area of a woman with a condom and prevents contact communicable diseases. Means for Solving the Problems A thin film made of a flexible material having high elasticity is formed, and the upper side is reinforced by a reinforcing material. The upper portion of the bag-like body is stretched to be worn through both feet. A bag-like body provided with an opening, two holes are formed on the side surface near the opening for passing one foot whose edges are reinforced by a reinforcing material, and the bag-like body opening is passed through the foot. Pulled up toward the waist and attached, the lower part of the bag-shaped body is a cylindrical body that can be inserted into the vagina, and reinforcing means made of a flexible material for suppressing expansion and contraction is arranged on all or part of the cylindrical body, Provide a female-worn condom with a vaginal fixture. Embodiments of the present invention will be described based on examples with reference to the drawings. FIG. 1 is a perspective view of the entire first embodiment of the present invention showing a shape when the bag-like body 1 is formed into a funnel shape and the reinforcing means 9 for suppressing expansion and contraction is made of a reinforcing material made of a flexible material. The bag-like body 1 as a main body is formed of a rubber-like thin film having high elasticity, and is constituted by a conical body 2 and a cylindrical body 3. Holes 4 are made at two places on the side surface of the cone 2, and the tip 5 of the tubular body 3 extending at the bottom is closed. A reinforcing member 6A made of a rubber ring is formed around the bag-shaped body opening 10, and a reinforcing member 6B made of a rubber ring is provided around the hole 4 on the side surface of the cone. A portion located at the opening of the vagina at the time of wearing is defined as a penis insertion port 7, and an internal fixing tool 8 is provided at the tip 5 of the cylindrical body 3. The internal fixing device 8 is inserted into the vagina inside the cylindrical body, is arranged so as to cover the uterus, and is pressed against the vaginal wall. In the embodiment, the internal fixing tool 8 is a position fixing ring. Reinforcement means 9 for suppressing expansion and contraction is arranged on the side of the body of the cylindrical body 3 inserted into the vagina in a strip shape, and the cylindrical body 3 expands and contracts due to friction with the penis and sticking to the penis. prevent. Although the reinforcing means 9 for suppressing expansion and contraction can be applied to the entire surface of the tubular body 3, it is desirable that the area be as small as possible in order to ensure good usability. In the case where the reinforcing means 9 for suppressing expansion and contraction is formed in a belt shape and the area thereof is minimized, it is necessary to join the internal fixing tool 8 so as not to shift from the reinforcing means 9 for suppressing expansion and contraction. As in the first embodiment shown in FIG. 1, reinforcing means 9 for suppressing expansion and contraction is provided in the upper half of the cylindrical body 3 in a band shape, and the periphery of the inner fixing tool 8 is installed, that is, the cylindrical body. When the reinforcement means 9 for suppressing expansion and contraction is applied to a large part of the lower half of 3, there is no need for fixing. The same effect can be obtained by forming the cylindrical body thick without using a reinforcing material, or by replacing the whole or a part of the cylindrical body with a material having poor elasticity. Affixing the reinforcing means 9 for suppressing expansion and contraction to the side surface of the cylindrical body as a cloth-like thin film of nylon or the like can be realized at a relatively low cost without any difficulty in the manufacturing process. By providing the reinforcing means 9 for suppressing expansion and contraction, it is possible to use a flexible material having high elasticity and to improve a feeling of use. In addition, the small conical body 2 can be stretched and worn to be used as an external fixture. The conical body 2 can be provided with a distortion in consideration of ease of mounting and body shape. In use, the opening 10 of the bag-like body 1 is stretched and a foot is inserted, and the foot is taken out from each of the two holes 4 provided on the side surface of the bag-like body 1 to reinforce the opening 10 of the bag-like body. The material 6A is pulled up to the waist. By stretching and wearing the bag-shaped body 1, there is no foreign matter in the vaginal opening at the time of wearing. Further, since the area around the opening of the vagina is covered with a condom, the possibility of transmission of a contact infection is extremely reduced. The cone 2 serves for external fixation,
The distal end of the tubular body 3 inserted into the vagina is arranged so as to wrap the uterus together with the internal fixing tool 8 placed inside the tubular body 3 and is pressed against the wall of the vagina to fix the inside. From the above, it is possible to use a flexible and thin material that is rich in elasticity, and a female-worn condom with a natural feel can be realized. The reinforcing member 6A of the bag-shaped body opening 10 can be provided with a winder 11 for winding the bag-shaped body 1 at the front part and the rear part at the time of mounting. A front winder 11A and a rear winder 11B at the time of wearing are arranged on the reinforcing member 6A in order to wind the rubber-like curtain forming the cone 2. By winding the front part or the rear part of the cone 2 at the time of mounting, the position of the vaginal opening and the position of the penis insertion port 7 of the condom can be matched, and after adjusting the position, the cylinder hitting the penis insertion part The state body 3 is pushed into the vagina together with the internal fixing tool 8 to be mounted. The size can be adjusted by winding up both the front take-up device 11A and the rear take-up device 11B, so that the size response can be given a wide range. FIG. 2 is a perspective view showing a side surface of the overall shape of the first embodiment in FIG. The length L of the front part of the cone 2 when mounted
1, that is, the distance from the penis insertion opening 7 to the front of the reinforcing member 6A is shorter than the length L2 of the rear portion of the cone 2 at the time of mounting, that is, the distance from the penis insertion opening 7 to the rear of the reinforcing member 6A. I do. At the time of mounting, the take-up device 11A or take-up device 11B is rotated to take up the cone 2 and adjust the length, so that the penis insertion port 7 coincides with the vaginal opening. FIG. 3 is a perspective view showing a shape when the present invention is mounted. When the bag 1 is funnel-shaped or when the area around the penis insertion opening 7 is funnel-shaped, the cone is extended and pulled up to the waist. , So that it is not stretched in a portion corresponding to the vaginal opening, that is, in the vicinity of the penis insertion opening 7, and no excessive force is applied to the vaginal opening upon mounting. Thereby, a natural feeling of wearing and a feeling of use can be obtained. FIG. 4 is an image diagram in a perspective view when the tubular body 3 is inserted into the vagina. The cylindrical body 3 is inserted into the vagina by using the internal fixing tool 8.
While holding it with your finger, push it into the vagina so that the tubular body 3 is turned upside down. FIG. 5 is a partially enlarged view of a perspective view including a partial cross-section of the tubular body 3 according to the second embodiment. A string 12 made of a flexible material is attached to the body of the tubular body 3 to be inserted into the vagina. Are shown in a mesh form. Even if the string 12 is replaced with a thread or a band 13, the shape is almost the same. A thread, a cord 12 or a band 13 made of a flexible material is spirally or mesh-wise arranged on the torso vagina side of the tubular body 3 to be inserted into the vagina, thereby reinforcing the cylinder and the thread, the cord 12 or the belt. The band 13 cuts into the inner wall of the vagina, which can prevent the condom from being displaced with respect to the vagina. Further, since the string 12 and the band 13 are also raised inside the tubular body 3, the contact area between the penis and the condom is reduced, and sticking of the penis to the condom is prevented. As described above, the displacement and deformation of the condom with respect to the vagina can be suppressed. FIG. 6 is an enlarged cross-sectional view of the cylindrical body 3 according to the second embodiment in which a string 12 made of a flexible material is disposed on the body of the cylindrical body 3 and is cut perpendicularly to the longitudinal direction. . The cord 12 cuts into the inner wall of the vagina to prevent the vagina from being displaced from the cylindrical body. Further, since the cord 12 also forms a convex portion inside the cylindrical body 3, the contact surface between the cylindrical body 3 and the penis is reduced, and the rubber-like thin film forming the cylindrical body 3 on the penis is reduced. Prevent sticking. The rubber-like thin film forming the cylindrical body 3 and the string 12
To form a gap 14 to absorb vaginal fluid. The vaginal secretion is pushed out of the vagina by the penis insertion movement. FIG. 7 is an enlarged cross-sectional view of the cylindrical body 3 according to the third embodiment in which a band 13 made of a flexible material is disposed on the body of the cylindrical body 3 and is cut perpendicular to the longitudinal direction. . The belt 13 cuts into the inner wall of the vagina to prevent the vagina from being displaced from the cylindrical body. Even if the band 13 is replaced with the band 13, there is no significant difference in the effect, but the shape of the cylindrical body 3 is stabilized, and the contact area between the penis and the cylindrical body 3 is reduced.
The effect of preventing sticking of the penis and the rubber thin film that forms the rubber is enhanced. FIG. 8 shows the cylindrical body 3 according to the fourth embodiment in which a string 12 made of a flexible material having a notch and having a narrow groove 15A is arranged on the body of the cylindrical body 3 so as to be perpendicular to the longitudinal direction. It is the expanded sectional view cut and shown. The thin groove 15A cut in the cord 12 has the effect of absorbing vaginal secretions. This has the effect of increasing the frictional resistance between the condom and the vagina, suppressing the displacement of the condom with respect to the vagina, and preventing the condom from deforming. FIG. 9 shows notches 15A and 1
It is sectional drawing which cut | disconnected and showed the cylinder 3 in Embodiment 5 in which the belt | belt 13 of the flexible material which formed 5B was arrange | positioned at the trunk | drum of the cylinder 3. Although there is no significant difference in the effect when the band 13 is replaced with the band 13 in place of the string 12, it is possible to cut the narrow groove 15B, thereby increasing the frictional resistance and increasing the absorption of vaginal secretion. According to the present invention, there is provided an opening for extending the upper portion of the bag-like body and wearing it through both feet by molding a thin film of a flexible material having a high elasticity and reinforcing the edges at the upper portion. A bag-like body provided with a portion, two holes for passing one foot whose end side is reinforced by a reinforcing material are formed in a side surface near the opening, and the bag-like body opening is passed through the leg to form a waist. The lower part of the bag-like body is made into a cylindrical body that can be inserted into the vagina, and reinforcing means made of a flexible material for suppressing expansion and contraction is arranged on the whole or a part of the cylindrical body. Since it is a female-worn condom with an internal fixture, it has the following effects. Since there is no foreign matter around the opening of the vagina at the time of wearing and the shape of the woman's body is maintained, a natural feeling can be obtained without impairing emotion during use. Since the periphery of the vaginal opening is covered with the condom, the safety regarding contraception can be ensured even if the penis is inserted without confirming the condom insertion port visually or tactually. In addition, since the area around the vaginal opening is covered with a condom, the effect of preventing contact infectious diseases can be enhanced. By arranging the reinforcing means of a flexible material, the strength of the cylindrical body 3 is increased, and a material having a more flexible and elastic property can be used. A close tactile sensation (a tactile sensation that is not used) is obtained, and a consumable female-worn condom can be obtained. Since it is possible to mold with a material having a high elasticity, the product has flexibility in size, so that the product can be applied to a wide range of body types and a natural feeling of wearing can be obtained.
