Abstract
Description
Technical Field
[0001] This utility model relates to the field of nursing pad technology, specifically to an antibacterial nursing pad that prevents side leakage. Background Technology
[0002] In daily life, the demand for feminine hygiene products such as panty liners is enormous. However, traditional panty liners are significantly inadequate in preventing side leakage and inhibiting bacteria. Traditional panty liners typically use a single absorbent layer and a simple edge-sealing design, making it difficult to effectively prevent side leakage, especially when large amounts of fluid are introduced. Furthermore, traditional sanitary napkins have weak antibacterial properties, making them prone to bacterial growth and affecting the user's health. These shortcomings not only affect user comfort but may also cause skin problems such as rashes and infections. Utility Model Content
[0003] The purpose of this invention is to provide an antibacterial nursing pad that prevents side leakage, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof antibacterial nursing pad, comprising a nursing pad body, the nursing pad body comprising a memory support skeleton arranged in a ring on the outer side, PE plastic strips evenly arranged on the top of both sides of the memory support skeleton, and a support mesh arranged in a ring on the inner side of the memory support skeleton, with hydrophilic polyurethane foam evenly arranged between the support mesh and the memory support skeleton, a core absorbent layer arranged in the middle of the nursing pad body inside the support mesh, a hexagonal honeycomb skeleton arranged inside the core absorbent layer, each of the hexagonal honeycomb skeletons being evenly filled with SAP and aerogel composite particles, a diffusing and diffusion layer arranged above the core absorbent layer, a skin-friendly antibacterial layer arranged on top of the diffusing and diffusion layer, and a support layer and a breathable PE film backing fixing layer arranged below the core absorbent layer.
[0005] Preferably, the skin-friendly antibacterial layer is provided with silk protein fibers, polyester fibers and nano silver particles inside, and the nano silver particles are embedded in the silk protein fibers and polyester fibers through blend spinning.
[0006] Preferably, the surface of the skin-friendly antibacterial layer is uniformly provided with raised cotton balls.
[0007] Preferably, the interior of the flow-guiding and diffusion layer is provided with a biomimetic leaf vein-shaped groove, and the biomimetic leaf vein-shaped groove includes a main groove provided along the length direction of the nursing pad body, and secondary grooves are evenly provided on both sides of the main groove.
[0008] Preferably, the secondary channels on both sides of the main channel are symmetrically arranged along the main channel, and the secondary channels are distributed at an inclined angle to the main channel.
[0009] Preferably, the multiple PE plastic strips are connected end to end to form a wavy structure.
[0010] Preferably, a connecting edge one and a connecting edge two are respectively provided at the middle position on both sides of the nursing pad body, and an adhesive layer is provided at the bottom of both the connecting edge one and the connecting edge two, and a release paper is detachably provided on the outside of the adhesive layer.
[0011] This invention provides a leak-proof, antibacterial nursing pad, which has significant advantages over existing technologies, as detailed below: 1. By creating a ring-shaped memory support frame on the outer side of the pad and evenly placing PE plastic strips on both sides and top, a stable support structure is formed, effectively preventing liquid leakage. In particular, the wavy structure formed by the end-to-end connection of the PE plastic strips further enhances the edge sealing and improves the anti-leakage effect. Hydrophilic polyurethane foam is evenly placed between the support mesh and the memory support frame; the foam expands upon contact with liquid, further enhancing the sealing effect.
[0012] 2. The hexagonal honeycomb framework within the core absorbent layer, uniformly filled with SAP and aerogel composite particles, significantly improves the absorption rate and capacity of the liquid. The hexagonal structure helps to evenly disperse the liquid and avoid local saturation. The biomimetic leaf vein-like groove design within the flow-guiding and diffusion layer, including the main groove and symmetrically arranged secondary grooves, can quickly guide the liquid to diffuse in all directions, ensuring uniform liquid distribution and preventing concentrated penetration.
[0013] 3. The skin-friendly antibacterial layer is embedded with silk protein fibers, polyester fibers, and nano-silver particles. Through blending and spinning technology, the nano-silver particles are evenly distributed, effectively inhibiting bacterial growth and protecting the user's health. The evenly distributed raised cotton balls on the surface of the skin-friendly antibacterial layer reduce the contact area with the skin, decreasing the damp and sticky feeling and improving comfort during use, while also helping to keep the skin dry.
[0014] 4. The combination of the memory foam support frame and the support mesh provides excellent support, ensuring that the nursing pad does not easily deform during use and maintains a stable structure. The breathable PE film backing layer at the bottom further enhances overall breathability, ensuring that the user's skin can breathe smoothly. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0018] Please see Figure 1-5 This utility model provides an embodiment of an anti-leakage antibacterial nursing pad, comprising a nursing pad body 2, the nursing pad body 2 including a memory support frame 16 arranged in a ring on the outer side, and PE plastic strips 10 evenly arranged on the top of both sides of the memory support frame 16. Multiple PE plastic strips are connected end to end to form a wave-shaped structure.
[0019] The outer side of the nursing pad body 2 is provided with a memory support frame 16. The memory support frame 16 is made of memory alloy material, which has excellent elasticity and memory function, and can restore its original shape after being subjected to external force, thereby providing a stable support effect.
[0020] Multiple PE plastic strips 10 are evenly distributed on both sides of the top of the memory support frame 16. The length and width of each PE plastic strip 10 are designed according to the size of the pad body to ensure its even distribution on the pad body. The multiple PE plastic strips 10 are connected end to end to form a wave-shaped structure. This wave-shaped structure not only enhances the lateral support of the pad but also effectively prevents liquid leakage.
[0021] The inner side of the memory support frame 16 is provided with a ring-shaped support net 23, and hydrophilic polyurethane foam 9 is uniformly disposed between the support net 23 and the memory support frame 16.
[0022] A support mesh 23 is provided in a ring around the inner side of the memory support frame 16. The support mesh 23 is made of high-strength nylon material, which has good breathability and durability. The mesh size of the support mesh 23 is moderate, which can ensure rapid liquid penetration while effectively preventing bacterial growth.
[0023] The support mesh 23 and the memory support frame 16 are tightly bonded together by a hot pressing process to ensure that the two will not shift or separate during long-term use.
[0024] Hydrophilic polyurethane foam 9 is uniformly disposed between the support net 23 and the memory support frame 16. The hydrophilic polyurethane foam 9 has excellent water absorption and air permeability, and can quickly absorb and lock in liquid to prevent back seepage and side leakage.
[0025] The inner side of the support mesh 23 contains a core absorbent layer 3 in the middle of the nursing pad body 2. The core absorbent layer 3 contains a hexagonal honeycomb skeleton 20. Each hexagonal honeycomb skeleton 20 is uniformly filled with SAP and aerogel composite particles 21.
[0026] The core absorbent layer 3 is a key component of this invention, located in the middle of the pad body 2. The main function of the core absorbent layer 3 is to efficiently absorb and lock in liquid, preventing backflow.
[0027] The core absorbent layer 3 contains multiple hexagonal honeycomb skeletons 20. Each hexagonal honeycomb skeleton 20 has a side length of 5mm and a thickness of 2mm, forming a stable three-dimensional structure. The hexagonal honeycomb skeleton 20 is made of a composite material of superabsorbent polymer (SAP) and aerogel. This material not only has excellent water absorption properties but also good air permeability and antibacterial properties.
[0028] Inside each hexagonal honeycomb skeleton 20, SAP and aerogel composite particles 21 are uniformly filled. The main function of the SAP particles is to rapidly absorb liquid, while the aerogel particles act as water-locking and breathable agents. The composite particles 21 have a diameter of 0.5-1 mm, ensuring that they are evenly distributed inside the hexagonal honeycomb skeleton 20 to maximize absorption and water-locking effects.
[0029] A flow-guiding and diffusion layer 4 is provided above the core absorption layer 3, and a skin-friendly and antibacterial layer 8 is provided on the top of the flow-guiding and diffusion layer 4. Raised cotton balls 5 are evenly distributed on the surface of the skin-friendly and antibacterial layer 8.
[0030] The skin-friendly antibacterial layer 8 is internally provided with silk protein fiber 17, polyester fiber 18 and nano silver particles 19, and the nano silver particles 19 are embedded in the silk protein fiber 17 and polyester fiber 18 through blend spinning.
[0031] Below the core absorbent layer 3, there is a support layer 12 and a breathable PE film backing fixing layer 13.
[0032] A flow-guiding and diffusion layer 4 is disposed above the core absorbent layer 3, and a skin-friendly and antibacterial layer 8 is disposed on top of the flow-guiding and diffusion layer 4. The surface of the skin-friendly and antibacterial layer 8 is evenly distributed with raised cotton balls 5 to reduce the contact area with the skin and reduce the feeling of dampness and stickiness.
[0033] The internal structure of the skin-friendly antibacterial layer 8 includes silk protein fibers 17, polyester fibers 18, and nano silver particles 19. The nano silver particles 19 are embedded in the silk protein fibers 17 and polyester fibers 18 through a blending spinning technology to form a composite fiber with antibacterial function.
[0034] Below the core absorbent layer 3, there is a support layer 12 and a breathable PE membrane backing fixing layer 13. The support layer 12 provides structural stability, while the breathable PE membrane backing fixing layer 13 ensures the breathability and fixation of the entire structure.
[0035] The support layer 12 is made of high-strength non-woven fabric with a thickness of 1-2 mm, providing good structural support and preventing the entire structure from deforming during use.
[0036] The breathable PE membrane backing fixing layer 13 is made of polyethylene (PE) material with a microporous structure on the surface to ensure good breathability.
[0037] Its thickness is 0.1-0.2 mm, making it lightweight and not affecting the overall flexibility of the structure.
[0038] The interior of the flow-guiding and diffusion layer 4 is provided with a biomimetic leaf vein-shaped groove 22, and the biomimetic leaf vein-shaped groove 22 includes a main groove 6 arranged along the length direction of the nursing pad body 2, and secondary grooves 7 evenly arranged on both sides of the main groove 6.
[0039] The secondary channels 7 on both sides of the main channel 6 are symmetrically arranged along the main channel 6, and the secondary channels 7 and the main channel 6 are distributed at an inclined angle.
[0040] The nursing pad body 2 of this invention includes a flow-guiding and diffusion layer 4. The interior of the flow-guiding and diffusion layer 4 is provided with biomimetic leaf vein-shaped grooves 22, which are designed to improve the flow and diffusion efficiency of liquids.
[0041] Main channel 6: A main channel 6 is provided along the length of the nursing pad body 2. The length of the main channel 6 is basically the same as the length of the nursing pad body 2, and its width is moderate to ensure that the liquid can flow smoothly along the main channel 6.
[0042] Sub-channels 7: Several sub-channels 7 are evenly arranged on both sides of the main channel 6. The number and spacing of the sub-channels 7 are designed according to actual needs to ensure that the liquid can be evenly diffused throughout the entire flow-guiding diffusion layer 4.
[0043] The main groove 6 is located at the center of the flow diffusion layer 4, and its length direction is consistent with the length direction of the nursing pad body 2.
[0044] The secondary tank 7 is symmetrically arranged on both sides of the main tank 6 to ensure that the liquid maintains symmetry during the diffusion process.
[0045] The secondary tank 7 and the main tank 6 are distributed at an inclined angle. This inclined angle is designed to increase the flow path of the liquid and prolong the residence time of the liquid in the flow-guiding diffusion layer 4, thereby improving the diffusion effect of the liquid.
[0046] The nursing pad body 2 has a connecting edge 1 and a connecting edge 2 11 respectively located at the middle of both sides. Both connecting edge 1 and connecting edge 2 11 have an adhesive layer 14 at their bottom. The outer side of the adhesive layer 14 is detachably provided with release paper 15.
[0047] When the user needs to change the nursing pad, simply peel off the release paper 15 and connect it to the underwear through the adhesive layer 14 at the bottom of connecting edge 1 and connecting edge 2 11.
[0048] In this embodiment, when using the product, remove the release paper 15 from the bottom of connecting edge 1 and connecting edge 2 11, align the adhesive layer 14 with the middle of the inner side of the underwear, and stick it on, ensuring that the connecting edge is parallel to the edge of the underwear. Apply even pressure (it is recommended to press with your palm for 5 seconds to ensure that the adhesive layer is fully bonded to the underwear fibers). This allows the frame to automatically conform to the hip curve, ensuring that the wavy PE plastic strip 10 fits tightly against the root of the thigh, forming a three-dimensional leak-proof edge. The raised cotton balls 5 of the skin-friendly antibacterial layer 8 contact the skin evenly, avoiding wrinkle accumulation. During use, the skin-friendly antibacterial layer 8 has antibacterial function, effectively inhibiting bacterial growth and protecting the user's health. After the liquid comes into contact with the diffusing layer 4, it diffuses to the entire diffusing layer 4 through the biomimetic leaf vein-shaped grooves 22. The leaf vein network formed by the main groove 6 and the secondary groove 7 should not have any local aggregation. The main function of the SAP particles inside the core absorption layer 3 is to quickly absorb liquid, while the aerogel particles play a role in water locking and breathability. The composite particles 21 ensure that they are evenly distributed inside the hexagonal honeycomb frame 20, maximizing the absorption and water locking effect.
