Description

Technical Field

[0001] This utility model belongs to the field of hygiene products, and specifically relates to a three-dimensional leak-proof sanitary napkin. Background Technology

[0002] Sanitary napkins are generally classified into basic sanitary napkins (wingless) and side-winged sanitary napkins according to their shape. The side wings, also known as protective wings, are an important component of sanitary napkins. Their main function is to secure the sanitary napkin in place during use and to prevent side leakage caused by heavy menstrual flow or daily activities. Currently, the material and structure of the side wings are mostly the same as the main body of the sanitary napkin, consisting of white ordinary SMS anti-stick water-repellent fabric or hot-air water-repellent fabric. While these two types of fabrics offer some water repellency, during heavy menstrual flow or strenuous activity, the relatively flat and low-profile leak-proof sides can still cause lateral leakage, resulting in blood stains on clothing and severely impacting the user experience. Furthermore, ordinary SMS anti-stick water-repellent fabric or hot-air water-repellent fabric can rub against the skin when in contact with the user's groin area, reducing comfort. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a three-dimensional leak-proof sanitary napkin. When menstrual flow is heavy or during strenuous activity, the leak-proof sides can block the flow and absorb it into the core, preventing staining of clothing.

[0004] This utility model is implemented as follows: a three-dimensional leak-proof sanitary napkin, comprising a sanitary napkin body and side wings;

[0005] The main body of the sanitary napkin, from top to bottom, consists of: a top layer, an absorbent core, a bottom film, and an adhesive backing.

[0006] The side wings are symmetrically attached to both sides of the sanitary napkin body, and the side wings include: a three-fold composite water-repellent fabric layer and a two-fold water-repellent fabric layer;

[0007] The three-fold composite water-repellent fabric layer and the two-fold water-repellent fabric layer contain folded structures. The three-fold composite water-repellent fabric layer has an "e"-shaped folded structure, with the tail of the "e" facing the outside of the sanitary napkin, forming three folds. The two-fold water-repellent fabric layer has a "c"-shaped folded structure, with both the head and tail of the "c" facing the outside of the sanitary napkin, forming two folds. The length of the head of the "c" is greater than the length of the tail, and the head of the "c" extends outward to the edge of the bottom film.

[0008] The "e"-shaped fold structure of the three-fold composite water-repellent fabric layer and the "c"-shaped fold structure of the two-fold water-repellent fabric layer form a three-dimensional leak-proof side; the three-dimensional leak-proof side includes a three-dimensional leak-proof side fixing part and a three-dimensional leak-proof side free part; the three-dimensional leak-proof side fixing part is fixed to the surface layer by a structural adhesive layer and is located outside the edge of the absorbent core; the three-dimensional leak-proof side free part is located above the inner side of the edge of the absorbent core;

[0009] The three-fold composite water-repellent fabric layer and the two-fold water-repellent fabric layer are connected and fixed at the three-dimensional leak-proof side fixing part.

[0010] Furthermore, the three-fold composite water-repellent fabric layer and the two-fold water-repellent fabric layer can also be completely connected and fixed at the three-dimensional leak-proof side fixing part plus the three-dimensional leak-proof side free part.

[0011] Furthermore, the three-fold composite water-repellent fabric layer is composed of an ES fiber water-repellent fabric layer and an air-permeable but liquid-impermeable PE membrane layer.

[0012] Furthermore, the width of the three-dimensional leak-proof side is 5mm-15mm.

[0013] Furthermore, the "e"-shaped fold structure of the three-fold composite water-repellent fabric layer is a completely composite and fixed whole with three folds.

[0014] Furthermore, the "C"-shaped fold structure of the two-fold water-repellent fabric layer is fixed using either ultrasonic technology or structural adhesive.

[0015] The beneficial effects of this utility model are: (1) When menstrual flow is large or when there is a surge during strenuous activity, the liquid can be blocked by the three-dimensional leak-proof side and absorbed into the core, which gives time for the liquid to spread longitudinally along the core and avoids soiling clothes; (2) The ES fiber water-repellent fabric is relatively soft and combined with the breathable and liquid-impermeable PE membrane, which is soft and comfortable and does not irritate the skin of the groin; (3) The breathable and liquid-impermeable PE membrane can achieve different color designs for the three-dimensional leak-proof side, meet the diverse aesthetic needs of users, and further enhance the user experience.

[0016] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description
