Description

Technical Field

[0001] This utility model relates to the field of maternal and child product technology, specifically to a moisture-absorbing material that prevents displacement and side leakage, as well as panty liners, sanitary napkins, and menstrual pants. Background Technology

[0002] Moisture-absorbing fabric is a widely used component in sanitary napkins, diapers, and other feminine hygiene products. It is typically placed directly on the moisture-absorbing area of ​​the product. When liquid passes over the fabric, it absorbs and locks in the liquid, preventing it from flowing out and staining clothing. Most existing moisture-absorbing fabrics are made of superabsorbent polymers combined with fluff pulp, which have excellent liquid absorption properties and effectively prevent leakage, allowing the wearer to maintain cleanliness and hygiene in special circumstances. They are also convenient to use and relatively inexpensive.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: While existing absorbent materials can effectively absorb menstrual blood and other fluids, if the wearer engages in vigorous exercise such as basketball or soccer, requiring running or lateral movements of the legs, the absorbent material can easily slide against the skin surface, causing it to deviate from its intended position. Consequently, menstrual blood may not drip onto the absorbent material, resulting in insufficient absorption and side leakage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a moisture-absorbing material with good skin adhesion and preventing displacement and side leakage, as well as panty liners, sanitary napkins, and menstrual underwear.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a moisture-absorbing material for preventing displacement and side leakage, comprising a superabsorbent polymer layer and a fluff pulp layer covering the superabsorbent polymer layer. The upper surface of the fluff pulp layer has an opening integrally formed, and a deformable groove integrally formed with the superabsorbent polymer layer is provided below the opening. The lower surface of the fluff pulp layer also has a weak groove integrally formed at the corresponding position of the deformable groove. Side guards made of sisal fiber are provided on both sides of the upper surface of the fluff pulp layer. When the moisture-absorbing material is inserted, the pressure of the clothing on the moisture-absorbing material causes the upper surface of the moisture-absorbing material to expand along the deformable groove, and the liquid flowing to both sides is absorbed through the side guards.

[0006] A further improvement is that silicone bumps are provided on the upper surface of the fluff pulp layer at the front and rear ends.

[0007] A further improvement is that the upper surface of the fluff pulp layer is provided with an arc-shaped leak-proof groove filled with sisal fibers on the inner side of the silicone bump.

[0008] A further improvement is that two V-shaped lateral resistance grooves are symmetrically distributed on the upper surface of the deformable groove.

[0009] To achieve the above objectives, the present invention may also adopt the following technical solution: a protective pad for preventing displacement and side leakage, comprising a protective pad sheet and a protective pad adhesive strip attached to the bottom side edge of the protective pad sheet, wherein the protective pad sheet is penetrated, embedded and fixed with the moisture-absorbing material as described above at its center position.

[0010] To achieve the above objectives, the present invention may also adopt the following technical solution: a sanitary napkin for preventing displacement and side leakage, comprising a sanitary napkin sheet and a sanitary napkin adhesive strip attached to the bottom side edge of the sanitary napkin sheet, wherein adhesive wings are sewn on both sides of the sanitary napkin sheet, and the absorbent material as described above is penetrated, embedded and fixed in the center of the sanitary napkin sheet.

[0011] To achieve the above objectives, the present invention may also adopt the following technical solution: a menstrual panty for preventing displacement and side leakage, comprising two waist-binding bodies and a covering sheet sewn between the two waist-binding bodies, wherein welding pieces are provided on both sides of the waist-binding bodies, and the covering sheet has a moisture-absorbing material as described above inserted and fixed in the center.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When this utility model is used, the pressure of the underwear causes the absorbent material to turn upward and the inner surface of the deformable groove to turn upward, thereby obtaining a larger area that fits the skin, thus increasing the contact area between the absorbent material and the skin. During exercise, the larger contact area prevents menstrual blood from flowing to other places without being absorbed. In conjunction with the side guards on both sides of the fluff pulp layer, some of the leaked liquid is blocked and efficiently absorbed, effectively preventing the absorbent material from shifting laterally during exercise and causing leakage.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] See Figure 1-5 As shown, the technical solution adopted in this specific embodiment is: a moisture-absorbing material for preventing displacement and side leakage, comprising a superabsorbent polymer layer 2 and a fluff pulp layer 1 covering the superabsorbent polymer layer 2. An opening is integrally formed on the upper surface of the fluff pulp layer 1, and a deformable groove 4 integrally formed with the superabsorbent polymer layer 2 is provided below the opening. A weak groove 11 is also integrally formed on the lower surface of the fluff pulp layer 1 at the corresponding position of the deformable groove 4. Sisal fiber material is provided on both sides of the upper surface of the fluff pulp layer 1. Side rail 3: When inserting absorbent material, the pressure of the clothing on the absorbent material causes its upper surface to expand along the deformation groove 4, absorbing liquid flowing to both sides. In use, the absorbent material is placed inside a panty liner, sanitary napkin, or menstrual panty. The superabsorbent polymer layer 2 of the absorbent material absorbs and preserves menstrual blood. When inserting, put on the panty liner, sanitary napkin, or menstrual panty with the absorbent material, ensuring it fits snugly against the skin of the lower body. Simultaneously, pull upwards during insertion. Underwear or menstrual pants use upward pressure to push the absorbent material upwards, causing the inner surface of the deformation groove 4 to turn up. Combined with the weak groove 11, this makes the entire absorbent material turn upwards and expand its upper surface area, thereby obtaining a larger area to fit the skin. This increases the contact area between the absorbent material and the skin, preventing menstrual blood from flowing to other areas without being absorbed during exercise. The side guards 3 on both sides of the fluff pulp layer 1 block and efficiently absorb some of the leaked liquid, effectively preventing leakage caused by lateral displacement of the absorbent material during exercise. Finally, the menstrual blood is guided into the absorbent resin layer 2 for absorption. If vigorous lateral movement occurs and the liquid tends to flow laterally, the sisal fiber side guards 3 can block the liquid from continuing to flow laterally. At the same time, the upward protrusion of the side guards 3 further increases the sliding resistance between the absorbent material and the skin, effectively preventing leakage caused by lateral displacement of the absorbent material during exercise.

[0021] On the upper surface of the fluff pulp layer 1, silicone bumps 5 are provided at the front and rear ends. The silicone bumps 5 are arranged in a semi-circular ring, which helps to greatly increase the friction resistance when the absorbent material is attached to the skin, further preventing the absorbent material from moving laterally. When arranged in a semi-circular ring, it can generate resistance to sliding in multiple directions, making the anti-sliding effect better, and thus making it less likely for the absorbent material to shift position.

[0022] The upper surface of the fluff pulp layer 1 is also provided with an arc-shaped anti-leakage groove 6 with an inner cavity filled with sisal fiber on the inner side of the silicone bump 5. This is beneficial for collecting and storing excess liquid when the liquid volume is large, thereby further improving the anti-leakage effect at both ends.

[0023] The upper surface of the deformable groove 4 also has two symmetrically distributed V-shaped lateral resistance grooves 7, which help to increase the frictional resistance between the positioning protrusion 4 and the skin at the contact point through the V-shaped resistance grooves 7, making it less likely to slip. At the same time, the V-shaped shape can provide resistance in multiple directions, thereby improving the anti-slip performance in various directions such as the lateral and longitudinal directions, so that the positioning protrusion 4 can be better and more accurately positioned after being inserted, preventing slippage that could lead to mispositioning.

[0024] This utility model also provides a protective pad for preventing displacement and side leakage, including a protective pad 101 and a protective pad adhesive strip 102 that is attached to the bottom side edge of the protective pad 101. The moisture-absorbing material 100 mentioned above is penetrated, embedded and fixed in the center of the protective pad 101.

[0025] This utility model also provides a sanitary napkin for preventing displacement and side leakage, including a sanitary napkin sheet 201 and a sanitary napkin adhesive strip 202 attached to the bottom side edge of the sanitary napkin sheet 201. Adhesive wings 203 are sewn on both sides of the sanitary napkin sheet 201, and the absorbent material 100 is penetrated, embedded and fixed in the center of the sanitary napkin sheet 201.

[0026] This utility model also provides a menstrual panty that prevents displacement and side leakage, including two waist-binding bodies 302 and a covering piece 301 sewn between the two waist-binding bodies 302. Welded pieces 303 are provided on both sides of the waist-binding bodies 302, and the moisture-absorbing material 100 is penetrated, embedded and fixed in the center of the covering piece 301.

[0027] The working principle of this invention is as follows: When using this invention, the absorbent material is inserted into a panty liner, sanitary napkin, or menstrual panty. The superabsorbent polymer layer 2 of the absorbent material absorbs and retains menstrual blood. When wearing the panty liner, sanitary napkin, or menstrual panty with the absorbent material, it is put on and placed against the skin of the lower body. Simultaneously, the panty liner or menstrual panty is pulled up, and the upward pressure from the panty liner or menstrual panty pushes the absorbent material upward, causing the inner surface of the deformation groove 4 to turn up. This, combined with the weak groove 11, causes the entire absorbent material to turn upward, increasing its upper surface area and thus obtaining a larger area in contact with the skin, thereby increasing the contact area between the absorbent material and the skin. The increased surface area during exercise prevents menstrual blood from flowing to other areas without being absorbed. Combined with side rails 3 on both sides of the fluff layer 1, this effectively blocks and efficiently absorbs any leaked liquid, preventing leakage caused by lateral shift of the absorbent during movement. Finally, the menstrual blood is guided into the absorbent resin layer 2 for absorption. If vigorous lateral movement occurs, causing a tendency for lateral flow, the sisal fiber side rails 3 can prevent further lateral flow. Simultaneously, the upward protrusion of the side rails 3 further increases the sliding resistance between the absorbent and the skin, effectively preventing leakage caused by lateral shift of the absorbent during movement.
