Description

Technical Field

[0001] The utility model relates to the technical field of anti-breast leakage pads, and more particularly to an anti-wrinkle anti-breast leakage pad. Background Art

[0002] Nursing pads, an indispensable companion for modern breastfeeding mothers, have earned widespread acclaim for their exceptional functionality and comfort. These compact and sophisticated hygiene products are specifically designed to address the common problem of breast milk leakage during breastfeeding. They quickly and effectively absorb excess milk, preventing it from seeping into clothing, keeping clothes pristine and new, and avoiding the embarrassment and inconvenience caused by breast milk leakage.

[0003] Nursing pads are made of high-quality, soft, breathable materials, such as pure cotton and non-woven fabrics. These materials are not only skin-friendly and comfortable, reducing irritation and friction on sensitive breast skin, but also have good moisture absorption and breathability, ensuring that the area around the breasts remains dry, reducing the risk of bacterial growth, and effectively maintaining breast health. Furthermore, the design of nursing pads also fully considers practicality and convenience. They are generally thin and form-fitting, fitting closely to the contours of the breasts and not prone to slipping or shifting, allowing mothers to breastfeed more freely. At the same time, many nursing pads are also equipped with an adhesive backing design, allowing mothers to stick them directly to their underwear and use them whenever they want, saving time and effort.

[0004] In short, nursing pads have become a must-have item for breastfeeding mothers due to their unique advantages. They can not only solve the troubles caused by milk leakage, but also improve the breastfeeding experience of mothers, allowing them to maintain confidence and elegance while enjoying intimate time with their babies.

[0005] Most existing nursing pads have spandex threads at the creases. The elastic force of the spandex threads pulls the nursing pads on both sides of the crease, creating a three-dimensional effect. However, the spandex threads at the creases are usually thin, and the elastic force of the spandex threads causes wrinkles in the nursing pads around the threads, resulting in a poor three-dimensional effect and poor comfort. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention aims to provide a wrinkle-resistant breast pad.

[0007] To achieve the above object, the utility model provides the following technical solution: a wrinkle-proof breast pad, comprising an outer layer and an inner layer, wherein PU foam is respectively adhered to both ends of the fold on the outer layer;

[0008] The inner layer includes a skin-friendly layer, a guide layer, a water-absorbing layer and a color-changing layer. One side of the skin-friendly layer is fixedly connected to the guide layer, the side of the guide layer away from the skin-friendly layer is fixedly connected to the water-absorbing layer, the side of the water-absorbing layer away from the guide layer is fixedly connected to the color-changing layer, and the color-changing layer is fixedly connected to the outer layer;

[0009] The color-changing layer is printed with a print made of a moisture-sensitive color-changing dye;

[0010] Hygrochromic dyes are primarily based on the effect of humidity in the air on the structure of the dye itself. When the ambient humidity changes, the dye can absorb or release water molecules, causing the structure or arrangement of the dye molecules to change. This structural change further affects the dye's absorption spectrum for the visible light portion of sunlight, thereby triggering a reversible change in color. Specifically, hygrochromic dyes usually contain one or more humidity-sensitive pigment molecules. These molecules may appear one color in a dry state and change to another color in a wet state. In order to make the color change effect more sensitive and vivid, auxiliary ingredients such as sensitizers and color enhancers are often added to hygrochromic dyes to enhance the dye's response speed to humidity changes and color expression.

[0011] When the water-absorbing layer absorbs breast milk, the moisture in the breast milk will seep into the color-changing layer, thereby changing the color of the print on the color-changing layer; and the depth of the print color is affected by the amount of breast milk absorbed by the water-absorbing layer. The depth of the print color can remind the wearer to replace the nursing pad in time.

[0012] Preferably, the skin-friendly layer is made of soft non-woven fabric.

[0013] Preferably, the guide layer is made of hot air non-woven fabric.

[0014] Preferably, the water-absorbing layer is composed of wood pulp and high-molecular water-absorbing resin.

[0015] Preferably, the color-changing layer is made of pure cotton.

[0016] Preferably, the outer layer is a breathable and waterproof composite membrane.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Use PU foam instead of spandex. PU foam is wider and has better three-dimensional molding effect. The wider PU foam will not cause wrinkles in the breast pad and is more comfortable.

[0019] 2. When the water-absorbing layer absorbs breast milk, the moisture in the breast milk will penetrate into the color-changing layer, thereby changing the color of the print on the color-changing layer; and the depth of the print color is affected by the amount of breast milk absorbed by the water-absorbing layer. The depth of the print color can remind the wearer to replace the nursing pad in time.

For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] Reference Figure 1 and Figure 2 The utility model provides a technical solution: a wrinkle-proof anti-breast leakage pad, comprising an outer layer 1 and an inner layer 2, wherein PU foam 3 is pasted on both ends of the fold on the outer layer 1, such as Figure 1 , using PU foam 3 instead of spandex yarn, PU foam 3 is wider, and the three-dimensional molding effect is better. The wider PU foam 3 will not cause wrinkles in the anti-nursing pad, and the comfort is also better;

[0029] like Figure 2 The inner layer 2 includes a skin-friendly layer 201, a guide layer 202, a water-absorbing layer 203 and a color-changing layer 204. The skin-friendly layer 201 is in contact with the human body and is more comfortable. One side of the skin-friendly layer 201 is fixedly connected to the guide layer 202, and the side of the guide layer 202 away from the skin-friendly layer 201 is fixedly connected to the water-absorbing layer 203. The side of the water-absorbing layer 203 away from the guide layer 202 is fixedly connected to the color-changing layer 204, and the color-changing layer 204 is fixedly connected to the outer layer 1;

[0030] The color-changing layer 204 is printed with a print made of a moisture-sensitive color-changing dye;

[0031] Hygrochromic dyes are primarily based on the effect of humidity in the air on the structure of the dye itself. When the ambient humidity changes, the dye can absorb or release water molecules, causing the structure or arrangement of the dye molecules to change. This structural change further affects the dye's absorption spectrum for the visible light portion of sunlight, thereby triggering a reversible change in color. Specifically, hygrochromic dyes usually contain one or more humidity-sensitive pigment molecules. These molecules may appear one color in a dry state and change to another color in a wet state. In order to make the color change effect more sensitive and vivid, auxiliary ingredients such as sensitizers and color enhancers are often added to hygrochromic dyes to enhance the dye's response speed to humidity changes and color expression.

[0032] like Figure 2When the water-absorbing layer 203 absorbs breast milk, the moisture in the breast milk will penetrate into the color-changing layer 204, thereby changing the color of the print on the color-changing layer 204; and the depth of the print color is affected by the amount of breast milk absorbed by the water-absorbing layer 203. The depth of the print color can remind the wearer to replace the anti-nursing pad in time.

[0033] Specifically, the skin-friendly layer 201 is made of soft non-woven fabric.

[0034] Specifically, the guide layer 202 is made of hot air non-woven fabric.

[0035] Specifically, the water-absorbing layer 203 is composed of wood pulp and high-molecular water-absorbing resin, and has a better water-absorbing effect.

[0036] Specifically, the color-changing layer 204 is made of pure cotton.

[0037] Specifically, the outer layer 1 is a breathable and waterproof composite membrane, which can be lighter in color or translucent, so that the color of the printing on the color-changing layer 204 can be easily observed;

[0038] With advances in materials science, PE membranes have emerged on the market, using specialized processing techniques or composite materials with other materials. These membranes can achieve a balance between waterproofness and breathability. For example, microporous membrane technology can create tiny pores in PE membranes that are large enough to allow the passage of small molecules such as water vapor, while effectively preventing the penetration of larger molecules such as water droplets, thereby achieving dual waterproof and breathable properties. Furthermore, composite membranes, created by combining them with other breathable materials (such as nonwoven fabrics and polyurethane), can also improve breathability while maintaining waterproof properties.

[0039] Working principle: When the water-absorbing layer 203 absorbs breast milk, the moisture in the breast milk will penetrate into the color-changing layer 204, thereby changing the color of the print on the color-changing layer 204; and the depth of the print color is affected by the amount of breast milk absorbed by the water-absorbing layer 203. The depth of the print color can remind the wearer to replace the anti-nursing pad in time.

[0040] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
