Technical Field
[0001] The utility model relates to the technical field of anti-leakage breast pads, in particular to a twin-spun ultra-thin core anti-leakage breast pad. Background Art
[0002] Anti-leakage breast pads are breast care products used by women, usually for absorbing breast milk overflow. They are usually round, with a diameter of three to five inches, and are made of absorbent materials such as cotton, superabsorbent polymers or cellulose materials.
[0003] The main function of the anti-leakage breast pad is to be worn inside the bra during breastfeeding to prevent breast milk from seeping into the clothes, keeping the breasts and clothes dry and clean. The anti-leakage breast pad generally has an adhesive strip or a fixing band to fix it inside the bra and prevent it from moving or falling off during activities. In addition to the basic absorption function, some high-end anti-leakage breast pads may also include a leak-proof layer or a non-slip design to improve the comfort and safety of use.
[0004] Currently, the anti-leakage breast pad is mainly composed of a surface layer, a wood pulp mixed polymer core wrapped with toilet paper, and a bottom film through gluing. This structure has five layers and has the defect of insufficient air permeability, resulting in the user feeling stuffy and uncomfortable; after the wood pulp polymer mixed core absorbs, the product will expand due to the expansion of the polymer, affecting the body feeling. Summary of the Utility Model
[0005] In order to make up for the above deficiencies, the utility model provides a twin-spun ultra-thin core anti-leakage breast pad, aiming to improve the problem that the product will expand due to the expansion of the polymer after the wood pulp polymer mixed core absorbs in the prior art.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a twin-spun ultra-thin core anti-leakage breast pad, including a twin-spun core, a plurality of rubber bands are equidistantly installed around the outer wall of the twin-spun core, a circumferential seal is installed inside the twin-spun core, a core opening is arranged on the inner wall of the twin-spun core, a surface layer is arranged outside the twin-spun core, a core bottom layer sizing is installed inside the twin-spun core, and a bottom water-repellent non-woven fabric is arranged on the inner side of the outer wall of the twin-spun core.
[0007] As a further description of the above technical scheme:
[0008] A core bottom layer sizing is installed inside the twin-spun core.
[0009] As a further description of the above technical scheme:
[0010] A bottom water-repellent non-woven fabric is arranged on the inner side of the outer wall of the twin-spun core.
[0011] The utility model has the following beneficial effects:
[0012] 1. In the present utility model, a three-layer structure breast pad can be obtained by using a twin-spun core, which is thinner and lighter than the traditional five-layer structure breast pad. After absorbing breast milk leakage, the liquid can be diverted to other positions of the product, effectively avoiding local expansion of the product caused by local absorption and preventing discomfort. The core can be made thinner and lighter. By using the twin-spun core, the product is thinner and lighter, avoiding the sense of heaviness during use and reducing the burden on the user.
[0013] 2. In the present utility model, hot melt adhesive is not used for bonding between the breast pad surface layer and the core. The surface layer and the core are bonded by hot pressing and embossing, which has better liquid permeability and can avoid the allergic swelling problem caused by hot melt adhesive. The soft and skin-friendly surface layer and bottom layer materials are bonded by hot melt adhesive and embossing to prevent the leakage of medium and high molecules in the core.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Refer to Figure 1 、 Figure 2 and Figure 3, an embodiment provided by the present utility model: a twin-spun ultra-thin core anti-leak breast pad, including a twin-spun core 1. A plurality of elastics 4 are evenly installed around the outer wall of the twin-spun core 1. A peripheral seal 2 is installed inside the twin-spun core 1. A core opening 3 is provided on the inner wall of the twin-spun core 1. A surface layer 5 is arranged on the outer side of the twin-spun core 1. A core bottom sizing 7 is installed inside the twin-spun core 1. A bottom water-repellent non-woven fabric 6 is arranged on the inner side of the outer wall of the twin-spun core 1;
[0021] Specifically, using the twin-spun core 1 can obtain a thinner anti-leak breast pad product, and after absorbing the leaked milk, it can divert the liquid to other positions of the product, effectively avoiding local expansion of the product caused by local absorption and avoiding causing discomfort in the body feeling; it has good softness and strong air permeability, can fit the human body better, and can avoid the allergy and airtightness problems caused by hot melt adhesive. The breast pad surface layer 5 and the core are not bonded with hot melt adhesive, and the surface layer 5 and the core are bonded by hot pressing and embossing, which has better liquid permeability and can avoid the allergy and swelling problems caused by hot melt adhesive. The bottom material uses spunbond meltblown water-repellent non-woven fabric, which can effectively ventilate while preventing leakage, solving the stuffy phenomenon of using pe film as the bottom layer. There are openings on all four sides of the core. When in use, the openings on the four sides of the anti-leak breast pad can avoid the accumulation of the cotton core and fit the human body better; the openings on the four sides can effectively accommodate the expansion of the core volume and avoid the core squeezing the peripheral seal 2 and causing the peripheral seal 2 to rupture.
[0022] Working principle: Using the twin-spun core 1, the twin-spun core 1 is composed of meltblown raw materials such as PP, PE, PLA, etc., wood pulp and SAP. In the twin-spun process, wood pulp fibers are combined with meltblown, and the materials are consolidated by heat sealing. And SAP or functional fibers can be added during the production process. This process can produce an absorption core thinner than the wood pulp + SAP core. Using the twin-spun core 1 can obtain a three-layer structure anti-leak breast pad, which is thinner than the traditional five-layer structure anti-leak breast pad. And after absorbing the leaked milk, it can divert the liquid to other positions of the product, effectively avoiding local expansion of the product caused by local absorption and avoiding causing discomfort in the body feeling. The twin-spun core 1 is not fixed and formed by hot melt adhesive, has good softness and strong air permeability, can fit the human body better, and can avoid the allergy and airtightness problems caused by hot melt adhesive; this core can be made thinner. Using the twin-spun core 1, the product is thinner, avoiding the heavy feeling during use and reducing the use burden of the user. The breast pad surface layer 5 and the core are not bonded with hot melt adhesive, and the surface layer 5 and the core are bonded by hot pressing and embossing, which has better liquid permeability and can avoid the allergy and swelling problems caused by hot melt adhesive. The soft and skin-friendly surface layer 5 and the bottom material are bonded by hot melt adhesive and embossing to avoid the leakage of medium and high molecules in the core. There are openings on all four sides of the core. When in use, the anti-leak breast pad bends naturally, and the openings on the four sides can avoid the accumulation of the core, and the product forms a bowl-shaped structure, which fits the human body better; after absorbing the milk liquid, the core expands, and the openings on the four sides can effectively accommodate the expansion of the core volume and avoid the core squeezing the peripheral seal 2 and causing the peripheral seal 2 to rupture.
[0023] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
