Problems solved by technology

However, since the condom is only wrapped around the skin of the erect penis, it does not form too much pressure, cannot generate greater friction, and cannot achieve the purpose of preventing sliding; in addition, different inner membrane materials will affect the high memory elasticity of the condom Performance and Security
[0010] Although researchers in this field have tried the above-mentioned different technical solutions, the actual application effect is not good, and the problem that the condom slides on the skin surface of the penis to form folds or even fall off during use cannot be solved.

Embodiment 1

[0069] In an embodiment of the condom of the present invention, the entire area of ​​the male side of the condom has a uniformly arranged cylindrical primary microstructure 8, such as Figure 4 shown. Where h is the height of the cylindrical structure, d is the diameter of a single cylindrical structure, and l is the average perimeter of a single cylindrical structure. Table 1 shows the male side area ratio of the condom calculated according to the structural parameters of the cylindrical structure.

[0072]

Embodiment 2

[0074] In an embodiment of the condom of the present invention, the entire region of the male side of the condom has closely arranged regular jagged primary microstructures 9, such as Figure 5 shown. The sawtooth structure is a regular regular pyramid, h is the height of a single sawtooth, w is the width of the bottom side of a single sawtooth, and α is the apex angle of the sawtooth cone. Table 2 shows the male lateral area ratio calculated from the structural parameters of the jagged microstructure.

[0075] Table 2 Area ratio when all areas on the male side have a regular jagged primary microstructure

[0076]

Embodiment 3

[0078] In an embodiment of the condom system of the present invention, the entire area of ​​the male side of the condom has closely-arranged irregular closely-arranged jagged primary microstructures 10, such as Figure 6 shown. The structural parameters of the irregular sawtooth microstructure are represented by average values, including: the average pitch L of the sawtooth, and the average height H of the sawtooth.

[0079] The average spacing L of the sawtooth and the average height H of the sawtooth include the two directions a and b that are orthogonal to each other on the test surface, which are respectively denoted as L a , L b and H a 、H b .

[0080] Using the micro-element method, the surface area of ​​the male side with irregular jagged microstructure is regarded as the area integral of the micro-element surface in the two directions a and b, and the area ratio of the male side is calculated by the following formula. The results are shown in Table 3 Show.

Abstract

The invention discloses an anti-slip condom. The anti-slip condom comprises a condom body, wherein the condom body is provided with an open end, a closed end, a male side and a female side, the part,which accounts for not less than 5% of the bottom surface of the male side, of the condom body is provided with a primary microstructure capable of increasing the surface area, and the area ratio of the total surface area including the primary microstructure on the unit area of the bottom surface of the male side to the unit area is 1.05-565.00. The condom can keep fit with a male penis during sexual intercourse, relative sliding between the condom and a penis skin can be relieved, wrinkles are not easy to form or the condom cannot fall off easily, mucosa damage is relieved, and unrealistic feeling is reduced; and the condom is beneficial to improving the condom using willingness of a consumer and preventing sexually transmitted diseases.

Description

technical field [0001] The invention relates to the technical field of condoms, in particular to an anti-slip condom that can better fit the skin of the penis; the condom provided by the invention can keep fit with the male penis during sexual intercourse, and can reduce the number of condoms and penis. Relative sliding between skins; easy to remove after sexual intercourse; this kind of condom is not easy to form wrinkles or fall off when used, which can reduce damage to mucous membranes and reduce unreality, and also help to improve consumers’ sexual experience and usage Condoms will, therefore, help prevent various sexually transmitted diseases. Background technique [0002] Condoms are widely used in human sexual life, and their routine functions include contraception and prevention of cross-infection of various sexually transmitted diseases (STDs), especially human immunodeficiency virus (HIV). When using a condom, the inner side of the mantle in contact with the male ...
