Description

Barrier ring condom

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a family planning article, and in particular to a barrier ring condom. BACKGROUND OF THE INVENTION With the development of society, people's pursuit of the quality of sexual life is getting higher and higher, and at the same time, in order to avoid unintended pregnancy in the sex life of men and women, condoms have become an indispensable family planning product in sexual life. The existing condom products are basically all-through structure. When the male ejaculates, it is easy to cause the semen to return to the back of the sleeve to cause discomfort; moreover, because the lubricating effect of the semen is also easy to cause the condom from the male penis Slip on the female vagina, not only endangers women's physical health, but also easily causes unwanted pregnancy. In principle, the existing contraceptive principle is to set up an artificial diaphragm between the penis and the vagina during sex life to block the semen from entering the female body to achieve the contraceptive effect. As a result, the true tactile feelings and sexual pleasures of both men and women in their sexual life are greatly reduced, resulting in many people who are extremely reluctant and even reject the psychology and feeling of using condoms, and other contraceptive methods are more or less It will have a negative impact on the user's body and is not conducive to the implementation and implementation of the family planning system in practice. Those skilled in the art are also constantly researching and wishing to use condom products with no toxic side effects as a contraceptive measure in the sex life of men and women, and at the same time, can improve the true tactile sensation and sexual pleasure of both men and women in sexual life. Based on the existing contraceptive principle, technicians are basically developing towards high-end materials and thinner and thicker sleeves in the research direction. However, due to the limitations of current scientific and technological development, high-end technology means higher costs. It is also very unfavorable for the promotion and application of products into the market. SUMMARY OF THE INVENTION The object of the present invention is to provide a barrier ring condom, which solves the problem that the current condom structure is unreasonable, which causes the semen to cause discomfort after male ejaculation and the accidental pregnancy caused by the sleeve slipping in the female vagina. The existing condom structure makes the real tactile sensation and sexual pleasure in male and female sexual life poor. In order to achieve the above object, the technical solution adopted by the present invention is as follows: a barrier ring condom comprising a sleeve made of an elastic material and having a closed end and an open end, and a seminal vesicle disposed at the top of the closed end of the sleeve, the sleeve The body is provided with a blocking ring which is close to the closed end and is integrally connected with the sleeve body. Wherein, the barrier ring is also made of an elastic material, usually, for convenience Manufacturing, the material of the barrier ring is the same as that of the sleeve material, and the integral molding process is adopted in the production method. As another option, different materials can also be used. In this case, the manufacturing method is to separately manufacture the sleeve body by using different materials. Block the two parts of the ring and connect the two together. Preferably, the elastic material is a natural latex or polyurethane. The two materials are conventional materials for making condoms, but the present invention is not limited thereto, and other materials capable of conforming to the national standard and capable of realizing the design principle of the present invention may be used. Specifically, the inner ring of the blocking ring is located on a side of the outer ring that is close to the closed end of the sleeve, and the angle between the wall of the closed end of the sleeve and the blocking ring is 5° to 90°. Further, the barrier ring is in the form of a diaphragm having a thickness of 0.01 to 5 mm, and the toroidal ring has a torus width of 3 to 20 mm, and the annular inner circle has a diameter of at least 2 mm. In order to better reflect the barrier effect, the number of the barrier rings is two or more. Wherein, the spacing between each two adjacent barrier rings is 3~6 mm. In order to ensure a good use effect, the distance between the barrier ring close to the seminal vesicle and the seminal vesicle is 10 to 35 mm. It is preferably 15 mm. In order to improve the real experience of both sexes in sex life, two solutions are designed in the present invention, as follows: One of the sleeves is provided with at least one connecting sleeve on the wall between the barrier ring and the open end of the sleeve body. Contact holes in the body and outside. The opening of the contact hole is performed on the basis of not affecting the overall connection structure of the sleeve body, and the condom is not damaged during normal use. Further, the contact holes are two or more, and all the contact holes are annularly distributed on the wall of the sleeve at least one turn. The shape of the contact hole is a combination of one or a combination of a circle, a circle, and a polygon, and may also be other shapes. Further, the distance between the contact hole closest to the barrier ring and the barrier ring is 3 to 45 mm, and if the distribution of the contact hole is more than two, the spacing between the contact holes of each ring is at least 3 mm, and the overall distribution does not exceed the sleeve. The open end of the body can be used. In addition, the distribution of the contact holes is not limited to the circular distribution, and can be specifically designed according to different nerve sensitive areas on the male penis. The second sleeve is cut between the barrier ring and the open end of the sleeve to form a front part of the sleeve with the closed end and The rear end of the sleeve body at the open end, the cut portion of the front portion of the sleeve body and the rear portion of the sleeve body are integrally connected by at least two connecting ribs, and an exposed hole is formed by the connecting rib and the edge of the cut portion. In order to increase the joint strength, the cut-off edge of the front section of the sleeve body or/and the rear section of the sleeve body is provided with an edge-sealing rib which is connected with the connecting ribs and has an integral structure. At the same time, the sleeve body wall of the front section of the sleeve body and/or the rear section of the sleeve body is provided with a thickening layer, and the thickness of the thickening layer is reduced by the cutting portion along the axial direction of the sleeve body. Among them, the setting of the edge banding and the thickening layer can be set at the same time or separately according to actual needs. Further, the distance between the front portion of the sleeve body and the cut portion of the rear portion of the sleeve body is 5 to 45 mm, and the distance between the contact hole closest to the cut portion of the rear portion of the sleeve body and the cut portion is 3 to 35 mm, but the barrier ring The setting shall not exceed the cut-off of the front section of the casing, and the distribution of the contact holes shall not exceed the total length of the rear section of the casing. Further, in order to increase more exposed positions, at least one contact hole inside and outside the connecting sleeve may be disposed on the sleeve wall of the rear section of the sleeve body. The arrangement of the contact holes is the same as in the previous scheme. The key point of the invention is that: by adding a barrier ring in the condom cover body, the defect of semen reflux leakage during use is effectively solved, and on the basis of this, by opening a hole in the condom cover body or by segmentation The design of the ribs and the connecting ribs form an exposed hole at the position near the front of the casing, so that the male penis site exposes a plurality of parts of the nerve sensitive area when using the condom, and exposes the nerve sensitive area to the female vagina during male sexual life. Really contact with friction, the two sides get more real sexual pleasure, breaking the conventional thinking in this technical field, without using high-end material technology or obtaining thinner film material molding technology or production technology, overcoming technical bias and proposing A new concept that allows people to gain more real tactile sensations and sexual pleasures in their sexual life, indicating a new direction in the development of technology in the field of condoms.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be further described below in conjunction with the accompanying drawings and embodiments, which include but not limited to the following embodiments. In the prior art, the condom usually adopts a through-body structure, that is, a sleeve body having a closed end and an open end, and a seminal vesicle provided at the top of the closed end of the sleeve body, which is mainly utilized in use. The contact between the head of the penis and the closed end of the sleeve seals the semen in the seminal vesicle, but when the male contracts after the ejaculation, the semen cannot be completely blocked, and the semen will flow back along the sleeve, especially when the seminal vesicle is When placed at a higher position than the case. On the one hand, the semen is reversed and surrounds the penis, which causes discomfort to the user and is also very unclean. On the other hand, the semen's lubrication effect on the penis makes the penis easily detach from the sleeve after ejaculation, and the sleeve is also slipped off. In women's vagina, it is very easy to cause unintended pregnancy, which not only causes serious psychological burden and economic burden to the parties, but also violates the family planning system. The present invention makes a special and ingenious design for the above situation, as shown in FIG. 1, that is, the existing sleeve body 1 and the seminal vesicle 2 are retained, and the barrier ring 3 is disposed near the closed end of the sleeve body, and Storage The wall of the capsule and the closed end of the sleeve together form a barrier space in which semen after male ejaculation is present. Due to the presence of the barrier ring, whether the male penis is in an expanded or contracted state, the penis head can be closely attached to the barrier ring to function as a closed barrier. Under this action, the semen is confined in the barrier space without backflow. Such a user's penis does not have the discomfort surrounding the semen, and the sleeve is also not easy to slip off in the female vagina causing an unwanted pregnancy. The specific arrangement for the barrier ring is as follows: Example 1 The barrier ring condom comprises a sleeve 1, a seminal vesicle 2 and a barrier ring 3. The barrier ring is in the form of a diaphragm ring. For ease of use, the thickness is usually equal to the thickness of the sleeve, and may be slightly smaller than the thickness of the sleeve. If the thickness of the barrier ring is slightly larger than the sleeve according to different actual needs. The thickness is not limited in the present invention. In the present embodiment, the thickness h of the barrier ring is 0.05 mm _. When manufacturing a condom product, according to the general standard, the diameter of the sleeve, that is, the outer diameter of the barrier ring is determined first. In this embodiment, the diameter of the sleeve is 52 mm, and the extension radius of the barrier ring from the sleeve wall to the center of the sleeve is 10 mm, that is, the torus width (ring width) t is 10 mm, and the inner diameter d of the barrier ring is 32 mm _; In order to make the barrier ring fit as much as possible to the head of the penis during use, the center of the barrier ring is slightly inclined toward the closed end of the sleeve, and the angle α between the one-side wide portion of the barrier ring and the sleeve wall of the closed end of the sleeve is 80. °, from its cross-sectional view, it constitutes a barb groove structure, refer to Figure 4 or Figure 6; in order to reserve sufficient barrier space, the distance between the barrier ring and the seminal vesicle L1 is 15mm. The sleeve, seminal vesicle and barrier ring are usually made of the same elastic material, preferably natural rubber or polyurethane, and are integrally molded by the existing manufacturing process, thereby ensuring excellent use effect. However, if it is made of different materials, it is sufficient to connect the two in the process. In use, the sleeve is placed on the male penis, and the barrier ring is naturally extended to the closed end of the sleeve by the pressure at the top of the penis. The elastic force of the barrier ring and the pressure at the top of the penis work together to ensure the barrier space. Closed; After the ejaculation, the penis contracts, and the barrier ring is retracted from the head of the penis by its own elasticity, keeping it close to the head of the penis, thus maintaining the closure of the barrier space until the end, effectively achieving the purpose of blocking semen reflux. In addition, the discomfort caused by semen surrounding the penis is avoided, the cleaning comfort of the male penis is improved, and the possibility that the semen is easily lubricated between the penis and the sleeve to avoid slipping easily, increases the safety of the contraceptive contraception. Embodiment 2 This embodiment differs from Embodiment 1 only in that the thickness h of the barrier ring is 0.01 mm. The design is to improve the comfort of use of the present invention and reduce the foreign body sensation of the penis head on the basis of ensuring the barrier effect. . Example 3 The difference between this embodiment and the embodiment 1 is that the thickness h of the barrier ring is 51Ώ1Τ1, and the invention is also slightly thick overall, but the possibility of damage of the condom during use is greatly reduced, and the contraceptive safety is increased. Sex. Embodiment 4 This embodiment differs from Embodiment 1 only in that the distance L1 between the barrier ring and the seminal vesicle is 35 mm, so that the barrier space is large, and more semen can be accommodated, thereby avoiding semen after the small space is squeezed. Break through the blockage. Embodiment 5 This embodiment differs from Embodiment 1 only in that the distance L1 between the barrier ring and the seminal vesicle is 10 mm, which can save the manufacturing material as a whole, and can also reduce the stacking of the penis head during use, thereby improving the men and women. Sexual experience. Embodiment 6 This embodiment differs from Embodiment 1 only in that the angle α between the barrier ring and the sleeve wall of the closed end of the sleeve is 90°, so that the space can be increased as much as possible while the distance L is fixed. Size, and can also effectively limit semen backflow. Embodiment 7 This embodiment differs from Embodiment 1 only in that the angle α between the barrier ring and the sleeve wall of the closed end of the sleeve is 5°, and the angle is designed to make the shape of the barrier ring and the shape of the penis head more In accordance with, it also reduces the foreign body sensation of the penis head during use. Embodiment 8 This embodiment differs from Embodiment 1 only in that the ring width t of the barrier ring is 3 inm, and correspondingly, the inner circle diameter is 46 mm. Therefore, although the barrier effect is not the best, it can also be reduced. Foreign body sensation at the head of the penis. Embodiment 9 This embodiment differs from Embodiment 1 only in that the ring width t of the barrier ring is 20 mm, and correspondingly, the inner circle diameter is 12 mm. The design is such that the penis head and the blocking ring are closely adhered to each other. Blocking the sealing effect of the space, thereby improving the effect of blocking semen backflow. Example 10 As shown in FIG. 2, the difference between this embodiment and the embodiment 1 is that the number of the barrier rings is two, and the spacing between the two barrier rings is 3 mm. The design is doubled by the two layers of the barrier ring. The barrier effect increases the effect of blocking semen backflow accordingly, and the spacing between the two layers of barrier rings is small, which does not have much effect on the experience of the actual experience. Embodiment U This embodiment differs from Embodiment 1 only in that the number of the barrier rings is two, and the spacing between the two barrier rings is 6 mm. The design improves the backflow semen by increasing the spacing of the two barrier rings. The buffer space is protected from squeezing and breaks through the barrier of the two layers. When the number of barrier rings is greater than two, the spacing can also be set according to the parameters in Embodiments 10 and 11. Several barrier rings can be set with the same parameters, but in order to better conform to the physiological characteristics of the penis, improve the comfort of use, It is better to use different parameters to form the barrier gradient. The preferred parameter selection can be set by one or more of the following parameters: the ring width of several blocking rings in the axial direction from the closed end to the open end The t gradually decreases (correspondingly, the inner diameter d gradually increases), the angle α gradually decreases, the thickness h gradually decreases, and the spacing of adjacent barrier rings gradually decreases. For example: Embodiment 12 The difference between this embodiment and Embodiment 1 is that the number of the barrier rings is three, the barrier ring near the seminal vesicle is the first one, and the second and third are sequentially along the central axis of the sleeve. The parameters of the three barrier rings are: the first barrier ring, the thickness h is 0.1mm, the ring width t is 12mm, the angle α is 85°, and the distance from the seminal vesicle is 15mm _{; the} second barrier ring, thickness h is 0.07mm, ring width t is 8mm, angle α is 70°, and the distance from the first barrier ring is 5mm _{; the} third barrier ring, thickness h is 0.05mm, ring width t is 5mm, angle α is 50 °, the distance from the second barrier ring is 3mm, thus forming a barrier gradient, which not only ensures the comfort of the front of the penis, but also improves the barrier effect by multiple layers of barrier. In the above embodiment, the arrangement of the barrier ring is mainly used to reverse the restriction of semen and prevent leakage. On the basis of this, the subsequent embodiments are further expanded, mainly aiming at the fact that the existing condom affects the real life of both men and women in the sexual life process. Feel the problem of experience and improve. Embodiment 13 As shown in FIG. 3 and FIG. 4, the difference between this embodiment and Embodiment 1 is that the nerve sensitivity of the penis is increased by opening the contact hole 4 on the wall of the sleeve between the barrier ring and the open end of the sleeve. Area, increase the real contact friction with the female vagina, get more real sexual pleasure. In this embodiment, the number of contact holes is three, centered on the central axis of the sleeve body, and is uniformly distributed in a ring shape on the wall of the sleeve body, and the distance L2 between the side edge of the barrier ring and the barrier ring is 10 mm; For the shape of a contact hole, it may be a circle, a circle, a combination of one or more of the polygons or other different shapes, and the shape may be the same or different for the three contact holes, and the size thereof is also The invention may be the same or different, and is not limited in the present invention. It is only required to ensure that the normal connection between the closed end and the open end of the sleeve is not affected after the contact hole is opened. The contact holes in this embodiment are three. An elliptical shape of the same size. In use, the closure of the barrier space is ensured on the basis of the embodiment 1, and the contact hole exposes the sensitive area of the penis nerve after the barrier ring, and this part of the area is blocked by the artificial diaphragm during the sex life of the male and female, male The penis and the female vagina can truly contact the friction, the two sides get more real sexual pleasure, and also reduce people's resistance to the use of condoms or rejection. Embodiment 14 The difference between this embodiment and the embodiment 13 is that the number of contact holes is seven, and four contact holes of the second ring are distributed on the basis of the arrangement of three contact holes of one turn of the embodiment 12, And the shape of the last four contact holes is square. As shown in Fig. 7, the distance between the two contact holes is 10mm. This design can expose more nerve sensitive areas on the penis, which can provide more real pleasure. . Embodiment 15 This embodiment differs from Embodiment 13 in that the number of contact holes is four, and the shape thereof is circular, and is divided into two rows of front and rear, two in a row, and is disposed on one side of the casing, such as As shown in Fig. 8, the distance between the front and rear rows of contact holes is 3 mm, and the design is aimed at a user who is more concentrated in the nerve sensitive area on the penis, so that the real pleasure is more intense. Embodiment 16 As shown in FIG. 5 and FIG. 6, this embodiment and all the foregoing embodiments are different in the casing structure. Based on Embodiment 1, the present embodiment cuts the casing 1 from the front part of the casing. 11 and the rear section 12 of the sleeve, the cut-off portion is located between the barrier ring and the open end of the sleeve body, and the cut-off portions of the front and rear sections of the sleeve body are integrally connected by the three connecting ribs 5, thereby exposing the joint ribs and the edge of the cut-off portion The hole exposes the nerve sensitive area on the penis, especially the front part of the penis, and maximizes the true contact between the male penis and the female vagina during the sexual life of men and women, so as to obtain the maximum degree of authenticity, greatly It reduces the male's resistance to the use of condoms, and it has the same effect as the design of the contact holes in Examples 13~15. For the setting of the connecting ribs, the sleeves are usually connected in a circumferentially uniform manner to the front and rear, so that the connection between the front and the back of the sleeve is evenly applied. In this embodiment, three connecting ribs with a length of 30 mm are used to form the central axis of the sleeve. The circumference is evenly distributed to connect the front and rear sections of the sleeve body, that is, the distance between the two sections of the front and rear of the sleeve body is 30 mm. For the number of connecting ribs, too little may result in insufficient joint strength, and too much may reduce the exposed area, so at least two are needed to ensure the stability of the connection, and preferably the number of connecting ribs is usually three to six. The most appropriate time. Further, in order to improve the joint strength, the edge of the cut portion of the front and rear portions of the sleeve body is provided with an edge seal rib 6 which is integrally connected with the connecting rib, and the joint frame formed by the joint rib and the edge rib is effectively enhanced. The connection between the two sections before and after the sleeve is firm. At the same time, a thickened layer 7 which is uniformly reduced along the axial direction of the sleeve wall by the edge of the sleeve is provided on the sleeve wall of the front and rear sections of the sleeve body, which further improves the connection firmness. Prevent damage to the two sections before and after the casing is in use. For the material of the connecting rib, the edge banding and the thickening layer, it is usually made of the same material as the casing. In actual production, the manufacturing mold can be designed accordingly, and the manufacturing method thereof is not described in the present invention. It should be noted that, according to actual needs, the setting of the edge banding and the thickening layer may be set at the same time or separately separately on the front part of the casing or/and the rear part of the casing, and the solutions included therein shall be protected in the invention. Within the scope. Embodiment 17 This embodiment differs from Embodiment 16 only in that the length of the connecting rib is 5 mm, that is, the distance between the two sections of the front and rear of the sleeve is 5 mm. The design is to increase the connection stability by shortening the connection distance. . Embodiment 18 This embodiment differs from Embodiment 16 only in that the length of the connecting rib is 45 mm, that is, the interval between the two sections of the front and rear of the sleeve is 45 mm, thereby increasing the area of the exposed hole and enabling the penis The nerve-sensitive area is exposed to a greater extent, further enhancing the user's authenticity experience. Embodiment 19 As shown in FIG. 5, the difference between this embodiment and the embodiment 16 is that, in combination with the design ideas of the embodiments 13-15, the contact hole 4 is disposed on the rear section of the sleeve, and the specific setting of the contact hole can be referred to. Embodiments 13 to 15 increase the exposed area of the corresponding part of the posterior part of the penis, so that the user can more realistically contact the friction during the sexual life process, thereby further improving the sexual life experience. Example 20 As shown in FIG. 9, the difference between this embodiment and the embodiment 16 is that the number of contact holes is seven, and the first ring is provided with three circumferentially uniform elliptical contact holes at the front of the rear portion of the sleeve, and Two ring-shaped contact holes of four squares, but the size of the four square contact holes is different, and the distance between the two contact holes is 10 nm, so that the penis can expose more nerve sensitive areas. Can provide more real pleasure. The above embodiments are only some of the embodiments of the present invention, and are not intended to limit the present invention, and the parameters of the barrier ring in the present invention can be arbitrarily selected and combined according to actual use effects. Based on the above structural design, in order to solve the same technical problem, even if some substantial changes or retouchings are made on the present invention, the essence of the technical solution adopted is still consistent with the present invention, and should also be in this Within the scope of protection of the invention.
