Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin technology, specifically to a multi-layered flow-guiding sanitary napkin. Background Technology

[0002] Sanitary napkins are personal hygiene products specifically designed for women during menstruation. They consist of several key parts, including a top layer, an absorbent layer, and a bottom layer. The top layer is usually made of soft and breathable material to ensure maximum comfort during use. The absorbent layer absorbs and locks in menstrual blood; it is typically made of highly absorbent polymers, which have extremely strong absorbency and can quickly absorb liquids. The bottom layer primarily serves to prevent leaks; it is generally made of waterproof material to prevent menstrual blood from seeping into clothing and to keep the user clean. In addition, sanitary napkins with a multi-layered diversion structure use a carefully designed diversion system to quickly guide menstrual blood to the absorbent layer and where it is efficiently absorbed. This not only keeps the surface of the sanitary napkin dry but also significantly reduces discomfort during use.

[0003] According to patent document CN206950279U, a sanitary napkin with a drainage channel is disclosed, including a sanitary napkin body, side wings, and a drainage channel. The sanitary napkin body is divided into a front and a back section, and the side wings are connected to the middle of the sanitary napkin body. The sanitary napkin body has a multi-layer composite structure, including a waterproof layer, a central absorbent layer, a medicated layer, an outer covering layer, and an antibacterial layer. A drainage channel is provided on the outer covering layer, extending from the front to the back of the sanitary napkin body. A parallel small side wing is also connected to one side of the drainage channel, and the small side wing also extends through and connects to the sanitary napkin body. Multiple stop buckles are fixed to the outer side of the small side wing, and these stop buckles connect each layer of the sanitary napkin body. The drainage channel can control lateral liquid flow and reduce lateral movement, while the small side wings can block large amounts of liquid at once, confining them to the vicinity of the drainage channel. This structure can effectively reduce the risk of side leakage and improve comfort.

[0004] When using sanitary napkins, we often encounter the problem of side leakage. This is mainly because the sanitary napkins are not absorbent enough. In order to improve absorbency, manufacturers usually increase the thickness of the sanitary napkins. However, the increase in thickness may bring another problem, namely, a decrease in comfort. In addition, the liquid absorbed by the sanitary napkin is usually first absorbed on the surface of the sanitary napkin and then gradually seeps into the interior of the sanitary napkin. This way of liquid absorption causes the liquid to easily spread on the surface of the sanitary napkin during use, thereby increasing the risk of side leakage. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-layered drainage structure sanitary napkin that effectively prevents side leakage while maintaining the thinness and comfort of the sanitary napkin.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sanitary napkin, wherein an absorbent layer is fixedly connected to the top of the sanitary napkin, and a storage layer is fixedly connected to the bottom of the sanitary napkin. Reinforcing wings are provided on both the left and right sides of the bottom of the sanitary napkin. These reinforcing wings further prevent side leakage during use, improving the sanitary napkin's performance. The absorbent layer is made of a highly absorbent resin material, possessing excellent absorbency and water-locking properties, enabling rapid absorption and locking of liquid, effectively preventing liquid from spreading on the surface of the sanitary napkin, thereby further reducing the risk of side leakage. The storage layer is made of a breathable and waterproof material, effectively storing absorbed liquid while maintaining the sanitary napkin's dryness and breathability, improving user comfort.

[0007] Preferably, the sanitary napkin includes a sanitary napkin body, with a sanitary napkin adhesive portion attached to both the front and back sides of the top of the sanitary napkin body, and a guide layer attached to the bottom of the inner wall of the sanitary napkin body. Through the setting of the guide layer, liquid can be guided to flow quickly to the storage layer, avoiding liquid accumulation inside the sanitary napkin body, and further improving the absorption efficiency and comfort of the sanitary napkin.

[0008] Preferably, protective wings are fixedly connected to the left and right sides of the sanitary napkin body, and the tops of the two protective wings, which are far apart from each other, are attached to the protective wing adhesive parts. By setting the protective wing adhesive parts, the protective wings can be pasted to both sides of the underwear to further fix the sanitary napkin and prevent it from shifting during use, thereby ensuring the stability and effectiveness of the sanitary napkin.

[0009] Preferably, the guide layer fixed to the bottom of the inner wall of the sanitary napkin body is attached to the top of the reservoir layer. This attachment ensures that the absorbed liquid flows quickly and smoothly into the reservoir layer, preventing liquid from stagnating between the guide layer and the reservoir layer, thereby further improving the absorbency and comfort of the sanitary napkin.

[0010] Preferably, the inner wall of the reservoir layer is made of superabsorbent polymer (SAP). By using SAP on the inner wall of the reservoir layer, the absorbency of the reservoir layer can be further enhanced, ensuring that the absorbed liquid can be firmly locked inside the reservoir layer and will not seep out again, thereby further reducing the risk of leakage. At the same time, the SAP also has good breathability, which can effectively keep the sanitary napkin dry and avoid discomfort caused by dampness. In addition, this material also has certain antibacterial properties, which can inhibit the growth of bacteria to a certain extent and protect the health of the user.

[0011] Preferably, the tops of the two wing reinforcement patches are respectively attached to the bottom of the two wings near the main body of the sanitary napkin. By setting the wing reinforcement patches, not only is the connection strength between the wings and the main body of the sanitary napkin enhanced, but an additional protective layer can also be formed between the wings and the underwear. Even when there is a lot of activity or changes in posture, it can effectively prevent side leakage and provide users with more comprehensive protection. In addition, the wing reinforcement patches are made of soft and skin-friendly materials to ensure that they will not cause discomfort to the user during use, further improving the comfort of the sanitary napkin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By incorporating a sanitary napkin, an absorbent layer, and a retention layer, the fit and comfort of the sanitary napkin are improved. It also effectively solves the problems of liquid accumulation and side leakage, providing female users with a safer and more convenient user experience. Its unique diversion layer design can quickly guide liquid, ensuring that the sanitary napkin always stays dry and reducing the discomfort caused by dampness.

[0014] 2. By incorporating wings and reinforced wing tabs, the stability of the sanitary napkin is further enhanced, eliminating the need for female users to frequently adjust its position during use, thereby improving overall user satisfaction. Attached Figure Description
