Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sanitary napkins, in particular to a sanitary napkin for night use with anti-back leakage performance. Background Art
[0002] Sanitary napkins are a type of care product used by women during menstruation. They not only absorb menstrual blood discharged from the body, but also help women keep their genitals clean and reduce the risk of infection by bacteria and other microorganisms.
[0003] The sanitary napkin is attached to the inside of the underwear by the adhesive on the side wings to absorb the menstrual blood flowing out of the vagina. However, when sleeping at night, the body is in a lying position, and the menstrual blood is very likely to flow from the gluteal groove to the back of the buttocks, causing back leakage of the menstrual blood. In response to this problem, patent CN219207724U discloses a detachable sanitary napkin with anti-back leakage, but its arc-shaped protrusion block for guiding menstrual blood is completely fixed to the sanitary napkin body and does not have the function of free movement. Therefore, it cannot fully contact the genitals, affecting the drainage effect. In addition, when the body turns over, the arc-shaped protrusion is easy to separate from the gluteal groove, so that the function of preventing back leakage cannot be achieved. Therefore, it is necessary to propose a night-time sanitary napkin with anti-back leakage performance to solve the above-mentioned problems. Utility Model Content
[0004] The utility model aims to provide a nighttime sanitary napkin with anti-back leakage performance, which makes the drainage column fit more closely with the genitals, avoids the drainage column from falling off due to body tossing during sleep, increases the sufficient contact area between the sanitary napkin and the genitals, thereby improving the sanitary napkin's absorption effect on menstrual blood and avoiding the risk of back leakage.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sanitary napkin for night use with anti-back leakage performance, comprising a sanitary napkin body, a drainage column and a connecting pad, wherein the upper end surface of the sanitary napkin body is provided with a contact surface, the left end of the drainage column is a free movable end, and is connected to the sanitary napkin body through the connecting pad at the right end, the connecting pad is fixed to the right end of the drainage column, and the connecting pad is bonded to the contact surface of the sanitary napkin body;
[0006] The drainage column has a multi-layer structure, including a surface layer, a permeable layer and a drainage core.
[0007] In order to stably connect with the connection pad, as a preferred nighttime sanitary napkin with anti-back leakage performance of the utility model, the contact surface has a flat surface structure.
[0008] In order to complete the assembly of the drainage column and the connecting pad, as a preferred night-time sanitary napkin with anti-back leakage performance of the utility model, the outer layer of the right end of the drainage column is provided with an adhesive surface, and an adhesive is bonded between the adhesive surface and the connecting pad.
[0009] In order to transport the menstrual blood drained by the drainage column to the sanitary napkin body through the connecting pad, as a preferred night-time sanitary napkin with anti-back leakage performance of the utility model, the connecting pad is composed of an outer layer and a permeable surface.
[0010] In order to facilitate the installation of the drainage column, as a preferred night-time sanitary napkin with anti-back leakage performance of the utility model, the middle part of the connecting pad has a cylindrical pit matching the diameter of the drainage column.
[0011] In order to be used for assembling the connection pad and the contact surface, as a preferred night-time sanitary napkin with anti-back leakage performance of the utility model, an adhesive is provided on the lower surface of the connection pad to adhere the connection pad to the surface of the contact surface.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] The utility model increases the sufficient contact area between the sanitary napkin and the genitals by arranging the drainage column, thereby improving the absorption effect of the sanitary napkin on menstrual blood and avoiding the risk of post-leakage.
[0014] One end of the drainage column has the function of being able to move freely, so that the drainage column and the genitals can be fitted more closely, thereby avoiding the problem of the drainage column falling off due to body tossing during sleep.
[0015] The good filling effect of the drainage column on the pubic area and gluteal groove can reduce the contamination of the pubic area, gluteal groove and other parts by menstrual blood and prevent the invasion of bacteria and other microorganisms. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figures 1 to 6 A sanitary napkin for night use with anti-back leakage performance comprises a sanitary napkin body 1, a drainage column 2 and a connecting pad 3, wherein the upper end surface of the sanitary napkin body 1 is provided with a contact surface 101, the left end of the drainage column 2 is a free end, and is connected to the sanitary napkin body 1 through the connecting pad 3 at the right end, the connecting pad 3 is fixed to the right end of the drainage column 2, and the connecting pad 3 is bonded to the contact surface 101 of the sanitary napkin body 1;
[0024] The drainage column 2 has a multi-layer structure, including a surface layer 201 , a permeable layer 202 and a drainage core 203 .
[0025] In this embodiment: the connecting pad 3 is adhered to the contact surface 101 by the adhesive 302 on the lower surface, and finally the sanitary napkin body 1, the drainage column 2 and the connecting pad 3 are assembled. By setting the drainage column 2, the sufficient contact area between the sanitary napkin body 1 and the pubic region can be increased, thereby improving the sanitary napkin's absorption effect on menstrual blood and avoiding the risk of back leakage. By making the left end of the drainage column 2 a free movable end, the drainage column 2 and the pubic region fit more closely, thereby avoiding the problem of the drainage column 2 falling off due to the body turning over during sleep, and the drainage column 2 has a good filling effect on the pubic region and the gluteal groove, which can reduce the contamination of the pubic region, the gluteal groove and other parts by menstrual blood and prevent the invasion of microorganisms such as bacteria.
[0026] As a technical optimization solution of the present invention, the contact surface 101 has a flat surface structure.
[0027] In this embodiment, the contact surface 101 has a flat surface structure, so that it can be stably connected to the connection pad 3 .
[0028] As a technical optimization solution of the utility model, the outer layer of the right end of the drainage column 2 is provided with an adhesive surface 204 , and an adhesive 205 is bonded between the adhesive surface 204 and the connection pad 3 .
[0029] In this embodiment, the adhesive surface 204 can be bonded to the connection pad 3 by the adhesive 205 , thereby completing the assembly of the drainage column 2 and the connection pad 3 .
[0030] As a technical optimization solution of the present invention, the connection pad 3 is composed of an outer layer and a permeable surface.
[0031] In this embodiment, the menstrual blood drained by the drainage column 2 is transported to the sanitary napkin body 1 through the outer layer and the permeable surface via the connecting pad 3 .
[0032] As a technical optimization solution of the utility model, the middle part of the connection pad 3 has a cylindrical pit 301 that matches the diameter of the drainage column 2.
[0033] In this embodiment: a cylindrical recess 301 is provided to facilitate installation of the drainage column 2 .
