Description

Description Female Wearable Condom Technical Field

The present invention relates to a condom worn by a woman, which ensures a natural feeling without impairing the feeling when worn, improves safety related to contraception, is easy to use, and has an effect of preventing contact communicable diseases. This is related to raising women's wearing condoms.

Technical background

The condom worn by conventional women is a ring made of a rigid elastic body attached along the cut surface of the opening of the bag made of a thin film of synthetic resin, and is used to fix the inside of the vagina made of an elastic body inside the bag. It has a ring and is made of a thicker material with poor elasticity compared to general male wearing condoms.

The characteristics of the material are those required to maintain a certain strength in the fixing method using a ring.The female-worn condom using this material has poor elasticity and is thick. The unnatural feeling was reduced.

In addition, a large ring for reinforcement and prevention of depression is formed at the opening of the bag around the entrance of the penis. Or the shape required to prevent the condom from being pushed into the vagina during use. there were. Patents and utility model applications related to the above were filed for Japanese patents and utility models: 1) 50-94 790, 2) 52-9696 97, 3) 59 — 1 37 7 1 4, ④ 開 0 60 3 302 13 、, 6 開 63 6 154 0 19, ⑥ 開開 4-4 ⑦ ⑦ ⑦ 57, ⑧Japanese Patent Laid-Open No. 4-5202710, ⑨Actual Japanese Patent Application Laid-Open No. 4-1338381, ⑩Japanese Patent Laid-Open No. 9-19544, ⑪Japanese Patent Laid-open No. Hei 10-2439456.

The application cited here does not mention the relationship between condom shape and material and the feeling of use. If the material and the thickness of the material specified by the shape are stiff or thick, the usability will be unnatural and uncomfortable.

One of the features that distinguishes these applications from the conventional women's wear condoms that are generally commercially available is in the way they are worn. A: The condom is attached to non-woven cloth or rubber pants. B: tie the strap to the thigh or waist and fix it. C: spread the condom exposed outside from the vagina into an adhesive strip and fix it with adhesive etc. Can be

For female condoms with adhesive strips listed as C, it is necessary to join them with another material 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. Since the adhesive strip is attached to the body, the feeling of use is unnatural.

It is difficult to say that it is a reasonable method because it requires operations such as applying lubricant and pasting glue and release paper. Adhering to the abdomen and buttocks is also troublesome.

In the case of using the band or strap as mentioned in B, it is difficult to keep the direction of tension and the force evenly 360 degrees outward from the vaginal opening. And tend to be biased. Also, since a force is applied to the joint between the string or the band and the condom, the material must have a certain degree of hardness, the part to be joined to the string and the band must be formed quite thick, or part of the material must be made of another material. Needs to be replaced. In addition, the position fixing ability during use is low, and the position cannot be fixed stably.

In the method of attaching to the pants mentioned as A, the size of the pants varies greatly from individual to individual, so it is necessary to prepare multiple sizes, and it also costs money to produce the pants themselves. Also, it is the same as sexual intercourse while wearing pants, and the feeling of use is poor. It is not enough to cope with the relative positional difference in the body of the vaginal opening depending on the body type of the wearer.

Depending on the body type of the wearer, the position of the vaginal opening varies in relative position throughout the body, but nothing has been mentioned about this. If the pants are made of rubber, the size will be flexible, but if the pants have a general shape, the cost will increase. Also, it is not possible to cope with the difference in the position of the vaginal opening depending on the body shape, as with fabric pants.

There has been an application for a condom attached to rubber pants, but there has been no application where the opening of the condom has been greatly stretched to make it wearable. Stretching the condom so that it can be worn reduces manufacturing costs and makes it possible to create a female-worn condom with excellent usability.

The above problem can be solved by using small rubber pants that are joined to a condom and stretched, but no application has been made assuming that the pants should be stretched greatly and worn.

In order to stretch, the material must have great elasticity. In other words, the tubular body inserted into the vagina also has great elasticity.

When the tubular body is a rubbery thin film with large elasticity, it separates from the vagina due to the secretion of vaginal secretions during sexual intercourse, and the tubular body sticks to the penis and coexists with the insertion movement. In addition, the condom tube moves in the vagina while expanding and contracting, which is no different from the feeling of using a condom worn by men. In addition, there is a risk of damage due to exercise.

How to reduce the thickness of a female condom and how to maintain the strength of the material when the thickness is reduced, and to prevent the condom from shifting in the vagina when the thickness is reduced However, it is important to keep the shape while preventing deformation, but nothing has been mentioned about this. For the above reasons, female condoms are not widely used. Disclosure of the invention

The present invention is a bag-like body formed of a thin film of a flexible material having high elasticity and provided with an opening at an upper part, and a hole at two places is formed on a side surface near the opening, and a lower part of the bag-like body is formed. Is a cylindrical body that can be inserted into the vagina and a female-worn condom with a vaginal fixture.

As a result, the condom opening is pushed open and both legs are inserted, the legs are pulled out of each of the two holes provided on the side and lifted up to the waist, and the cylindrical body is inverted, into the vagina together with the vaginal fixing device. Buy. This prevents the condom from sticking to the body outside the vagina and preventing foreign matter from hanging around the vaginal opening.

Reinforcing means for suppressing expansion and contraction is provided on the whole or a part of the cylindrical body. Because the elasticity of the cylindrical body is suppressed by this, even if secretion fluid is secreted into the vagina and slippage is improved, the condom moves away from the vagina and sticks to the penis and moves inside the vagina while expanding and contracting Is lost. The reinforcing means for suppressing the expansion and contraction is a cloth-like thin film. During the manufacturing process, it is easy to attach a cloth-like thin film to a part of the condom. In addition, female-worn condoms with reduced elasticity at the vaginal opening can be easily manufactured.

In addition, at least the vicinity of the cylindrical body located at the vaginal opening when the condom is attached is formed in a mouth shape. As a result, even when the condom opening is greatly stretched and worn, the stretching force does not reach the vicinity of the vaginal opening, and no excessive force is applied from the vaginal opening to the inside of the vagina. A winding device for winding the bag is disposed at the opening of the bag. By winding the front or rear part of the bag from the end with a winder, it is possible to adjust the position of the vaginal opening of the body and the position of the penis insertion opening of the condom, making it easy to use. It can be a condom.

In the next embodiment, a thread, a string or a band made of a flexible material is spirally or meshed on the body of a cylindrical body to be inserted into a vagina. The cord or band increases the frictional resistance with the inner wall of the vagina and suppresses the movement of the condom in the vagina.

A cut is made in the longitudinal direction of the cord or band to form a thin groove. The narrow groove absorbs the secretion fluid in the vagina and pushes it out of the vagina, thereby increasing the frictional resistance between the string or band and the inner wall of the vagina and suppressing the movement of the condom in the vagina.

The present invention will be described in more detail with reference to the accompanying drawings. Fig. 1 shows a bag-like body 1 made of a thin film of a flexible material with high elasticity and provided with an opening 2 at the top, and holes 3 1-3 2 at two places on the side near the opening 2 FIG. 2 is a perspective view of a whole of a female-woman-type condom in which a lower part of the bag-like body 1 is a cylindrical body 4 that can be inserted into the vagina and a position fixing device 5 in the vagina is arranged.

The entire shape of the bag-like body 1 is formed in a funnel shape, the upper part is a cone 6, and the reinforcing means 41 arranged inside the lower cylindrical body 4 to suppress expansion and contraction is a cloth-like thin film 4 1 1 It shows the configuration in the case.

The bag-shaped body 1 as a main body is formed of a rubber-like thin film having a high elasticity, and is mainly constituted by a cone 6 and a cylindrical body 4. Holes 31.32 are made at two places on the side of the cone 6, and the tip 4 2 of the cylindrical body 4 extending at the bottom is closed.

A flexible and elastic rubber-like reinforcing material 21 is formed around the bag-shaped body opening 2 and a similar elastic and flexible material is formed around the hole 3 1.3 2 on the side of the cone. Reinforcement material 3 1 1-3 1 with a flexible rubber ring is provided. The position of the condom located at the vaginal opening of the body at the time of wearing is the penis insertion port 4 3, and the position fixing tool 5 for the condom inside the vagina within the vagina is located at the tip 42 of the cylindrical body 4 Arrange the rings 5 1.

The position fixing device 5 is inserted into the vagina in the inside of the tubular body 4, is arranged so as to cover the uterus, and is pressed against the inner wall at the back of the vagina. In the embodiment, the position fixing tool 5 is the position fixing ring 51. However, the same effect can be obtained even if the position fixing tool 5 is an arm. On the side of the torso of the tubular body 4 inserted into the vagina, a cloth-like thin film 4 1 1 1, which is a reinforcing means 4 1, that suppresses expansion and contraction, is arranged in a band shape, and the tubular body 4 is used to friction with the penis and the base. Prevents stretching and deformation that can occur as a result of sticking and sliding in the vagina.

The reinforcing means 41 for suppressing expansion and contraction is formed outside the condom in use, in the inside of the tubular body 4 in FIG. It is possible to attach the reinforcing means 41 for suppressing expansion and contraction to the side surface of the cylindrical body 4 as the cloth-like thin film 4 1 1 without any difficulty in the manufacturing process, and it can be realized at a relatively low cost. It is also possible to form a thick part of the cylindrical body 4 as the reinforcing means 41 for suppressing expansion and contraction.

By providing the reinforcing means 41 for suppressing expansion and contraction, it is possible to use a flexible material having high elasticity as the material of the bag-like body 1 and to improve the feeling of use. The reinforcing means 41 for suppressing expansion and contraction increases the strength of the tubular body 4 and can prevent deformation caused by friction with the penis and sticking to the penis. Since the expansion and contraction of the cylindrical body 4 can be suppressed, the cone 6 can be used as a position fixing device outside the vagina.

The cone 6 can be distorted in consideration of the size of the wearing and the shape of the body.

FIG. 2 is a perspective view showing a side surface of the entire embodiment 1 shown in FIG. The length L 1 at the front of the cone 6 when fitted, the distance from the penis 揷 inlet 4 3 to the front 2 11 1 of the reinforcement 21, is The length L 2, that is, the distance from the penis 揷 inlet 4 3 to the rear part 2 1 2 of the reinforcing member 21 is formed.

Reinforcing material 21 at the opening 2 of the bag-like body has a front part 2 1 1 and a rear part 2 1 2 at the time of mounting. 7 1 and rear take-up device 7 2 are provided.

By winding the front part (L 1) or the rear part (L 2) of the cone 6 at the time of wearing, it is possible to make the position of the vaginal opening of the body coincide with the position of the penis 揷 entrance 43 of the condom, After adjusting the position, the cylindrical body 4 that hits the penis insertion part is pushed into the vagina together with the position fixing ring 51 and is attached, so the difference in the relative positional relationship in the body of the vaginal opening due to the difference in body shape Can respond.

By rotating both the front take-up device 71 and the rear take-up device 72, the size is increased by winding up the front (L1) and rear (L2) of the cone 6 at the same time. It can be adjusted, further expanding the range of size adaptability.

FIG. 3 is an imaginary view showing a shape at the time of mounting in a perspective view. In use, the opening 2 of the bag 1 is stretched and a leg is inserted, and the leg is taken out of each of the two holes 3 1.3 2 provided on the side surface of the bag 1 to open the bag. Pull up the stiffener 21 in part 2 to the waist. The cylindrical body 4 is inserted into the vagina together with the position fixing ring 51. By stretching and attaching the cone 6 which is a part of the bag-like body 1, foreign matter at the opening of the vagina at the time of attachment is eliminated. In addition, since the area around the vaginal opening is covered with a condom, the possibility of transmission of contact infection is extremely low.

If the bag 1 is funneled or the area around the penis 3 inlet 4 3 is funnel-shaped, the bag 1 is stretched and pulled up to the waist. Since it is successively stretched from 1 to the direction of the cylindrical body 4, it is pulled near the site corresponding to the vaginal opening, that is, near the penis 掙 entrance 43. It is not stretched and does not apply excessive force to the vaginal opening and the inside of the vagina when worn. As a result, a natural feeling of wearing and use can be obtained.

FIG. 4 is an imaginary perspective view showing how to insert the tubular body into the vagina. While holding and holding the position fixing ring 51 with your finger, push it into the vagina so that the tubular body 4 is turned upside down. The position fixing ring 51 regains its shape inside the condom inside the vagina, is positioned so as to wrap around the uterus, and is pressed against the inner wall of the vagina. Thus, the position of the condom inside the vagina is fixed, and the cone 6 wraps around the buttocks and fixes the position outside the vagina.

From the above, it is possible to use a flexible and thinner material that is rich in elasticity, and a female-worn condom with a natural feel can be realized.

FIG. 5 is an enlarged view of a perspective view including a partial cross section of the tubular body according to the first embodiment. This is an example of arrangement. The figure is based on the assumption of use, and the cylindrical body 4 is a state in which the state of FIG. 1 is reversed. The cutting position is on the line X-X in FIG. The reinforcing means 41 is made of cloth-like reinforcing material 4 1 1, and is applied to about half of the tip of the cylindrical body 4, that is, to the majority around the position fixing ring 51, and to the other half. Arrange them in thin strips to minimize the area. Attachment of the cloth-like reinforcing material 4 11 to the side surface of the tubular body 4 during the manufacturing process can be realized at a relatively low cost without any difficulty in the manufacturing process. Although the cloth-like reinforcing material 4 11 can be applied to the entire surface of the tubular body 4, it is desirable that the area be as small as possible in order to ensure good usability. The same effect can be obtained by forming the tubular body 4 thick without using a reinforcing material, or by replacing the whole or a part of the tubular body 4 with a material having poor elasticity.

FIG. 6 is a cross-sectional view showing a structure of a cut surface when the tubular body 4 is used. The cloth reinforcing material 4 1 1 is located on the outside, that is, on the vagina side in use. It is. As a result, a natural tactile condom can be realized.

FIG. 7 is an enlarged view of a perspective view including a partial cross section of the tubular body 4 in the second embodiment. This is an example in which reinforcing means 41 for suppressing expansion and contraction provided on the body of the tubular body 4 inserted into the vagina is a string 4 12 made of a flexible material and arranged in a mesh form. The cutting position is the same as on the X-ray in FIG. Even if the string 4 12 is replaced with a thread or a band 4 13, the shape is almost the same.

A thread or string made of a flexible material is laid on the torso vagina side of the tubular body 4 to be inserted into the vagina, and the strap 4 1 2 or the band 4 13 is arranged spirally or in a mesh to reinforce the cylinder and the thread. The string 4 1 2 or the band 4 13 increases the frictional resistance with the inner wall of the vagina and can prevent the condom from being displaced with respect to the vagina.

Also, when used, the string 4 12 and the band 4 13 also rise inside the tubular body 4, so that the contact area between the penis and the condom is reduced, and the condom is not stuck to the penis. With the above, the displacement and deformation of the condom with respect to the vagina can be suppressed.

FIG. 8 is an enlarged cross-sectional view of the tubular body 4 in Example 2 in which a cord 4 12 made of a flexible material is arranged on the body of the tubular body 4 and is cut perpendicular to the longitudinal direction. . The cords 4 1 2 increase the frictional resistance between the inner wall of the vagina and prevent the vagina from displacing the cylindrical body. In addition, since the cords 4 1 and 2 also form a convex portion inside the cylindrical body 4, the contact surface between the cylindrical body 4 and the penis is reduced, and the rubber-like thin film that forms the cylindrical body 4 on the penis is formed. Prevent sticking.

A gap 414 is formed between the rubber thin film forming the cylindrical body 4 and the string 412 to absorb vaginal secretions. The vaginal secretion is pushed out of the vagina by the penis insertion movement.

FIG. 9 is an enlarged cross-sectional view of the cylindrical body 4 in Example 3 in which a band 4 13 made of a flexible material is disposed on the body of the cylindrical body 4 and is cut perpendicular to the longitudinal direction. . The cutting position is the same as on the line XX in FIG. Obi 4 13 increases the frictional resistance with the vagina and prevents the vagina from displacing the cylindrical body. There is no significant difference in the effect when the band 4 13 is replaced with the band 4 13 instead of the string 4 1 2, but the shape of the cylindrical body 4 is stabilized, and the rubber thin film and the veneer forming the cylindrical body 4 stick together. Increase the effect of preventing.

Threads and cords 4 1 2 or obi 4 13 increase the frictional resistance between the inner wall of the vagina, suppress the displacement of the vagina and the cylindrical body, prevent deformation of the condom and damage caused by it, and reinforce Because of the effect, the product can be made thinner and the usability can be improved.

Fig. 10 shows a case in which the string 4 12 made of a flexible material having a narrow groove 4 15 is arranged on the body of the tube 4 and the tube 4 in Example 4 is cut perpendicular to the longitudinal direction. It is the expanded sectional view shown. The cutting position is the same as on the X-ray in FIG.

The narrow groove 4 15 cut in the string 4 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 condom's displacement with respect to the vagina, and preventing the condom from deforming. Fig. 11 shows a fifth embodiment in which a band 4 13 made of a flexible material having a narrow groove 4 1 5 and a narrow groove 4 16 and a narrow groove 4 17 is arranged on the body of the cylindrical body 4. FIG. 4 is a cross-sectional view of a tubular body 4 cut perpendicularly to a longitudinal direction. The cutting position is the same as that on the X-ray in FIG.

Although there is no significant difference in the effect when the band 4 13 is replaced with the band 4 13, the vagina because the narrow groove 4 16 and the narrow groove 4 17 can be carved and the number of grooves can be increased. Increases endocrine fluid absorption and increases frictional resistance.

Condoms and vagina because the narrow groove 4 15 cut in the string 4 12 and the narrow groove 4 15 and the thin groove 4 16 cut in the obi 4 13 have the effect of absorbing vaginal secretions This increases the frictional resistance of the condom and suppresses the misalignment of the condom with respect to the vagina, thus preventing the condom from being deformed and causing damage.
