Description

Technical Field

[0001] The utility model relates to the technical field of disposable sanitary products, in particular to a flexible sanitary napkin. Background Art

[0002] Sanitary napkins are disposable sanitary products used in daily life. Female consumers have increasing requirements for the comfort of sanitary napkins. The front and back ends of traditional sanitary napkins are usually designed with embossed seals. Although they have a certain aesthetic effect, they may reduce the softness and comfort of the product, easily crush the product, resulting in rough seals, and easily cause the product to curl around, affecting the product appearance and wearing comfort. At the same time, existing sanitary napkins are also prone to leakage from the front and back and from the sides.

[0003] Chinese patent application number: CN201921408008.6 discloses a soft sanitary napkin, the body of which is a three-piece structure, formed by hot pressing two wing pieces at the left and right ends and a main body piece in the middle, and a side leakage blocking groove is formed at the pressing part, the body of which is sealed with a 360-degree embossed edge, and the main body piece includes a non-woven surface layer, a guide layer, a water-absorbing layer and a breathable bottom film stacked from top to bottom, the water-absorbing layer includes dust-free paper and polymer water-absorbing paper, the surface of the polymer water-absorbing paper is evenly provided with high-loft non-woven fabric, and the upper surface of the non-woven surface layer is provided with compression grooves by hot pressing. The patent design has embossing around the seal, which may reduce the softness and comfort of the sanitary napkin. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes a flexible sanitary napkin, which solves the technical problems of the existing sanitary napkins being poor in softness and prone to leakage.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A flexible sanitary napkin comprises a sanitary napkin body, with the length direction of the sanitary napkin body as the longitudinal direction and the width direction as the transverse direction. The sanitary napkin body comprises a surface layer, a liquid-absorbing layer, and a liquid-impermeable bottom layer which are stacked in sequence from top to bottom. The surface layer is made of pure cotton material and is provided with a plurality of tiny concave and convex portions formed by flexible embossing. An absorbent core is arranged in the liquid-absorbing layer, and the absorbent core comprises a high-loft non-woven fabric and a water-absorbing resin filled in the high-loft non-woven fabric. First transverse liquid-conducting grooves are arranged at the front and rear ends of the absorbent core, and second longitudinal liquid-conducting grooves are arranged between the first liquid-conducting grooves.

[0007] Further:

[0008] The first liquid-conducting groove and the second liquid-conducting groove are connected.

[0009] The first liquid-conducting groove and the second liquid-conducting groove are waist-shaped structures.

[0010] The absorbent core is provided with a third liquid guiding groove arranged along the edge of the absorbent core, the third liquid guiding groove surrounds the first liquid guiding groove and the second liquid guiding groove, and the third liquid guiding groove is a waist-shaped structure.

[0011] The liquid-absorbing layer further comprises a wrapping layer, and the wrapping layer wraps the absorbent core in a U shape.

[0012] The concave parts and convex parts are arranged transversely to form a multi-row structure, and the convex parts and concave parts in each row are arranged at intervals.

[0013] The liquid-impermeable bottom layer is a PE breathable film.

[0014] Protection wings are arranged on both sides of the surface layer.

[0015] The surface layer is provided with a plurality of air-permeable and liquid-conducting holes.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are:

[0017] The materials used for the surface layer and the absorbent core of the utility model make the sanitary napkin body feel delicate and soft, and are skin-friendly and non-irritating when used. The convex parts and concave parts can increase the friction between the surface layer and the skin to prevent the sanitary napkin body from sliding when used. The first liquid guide groove is arranged horizontally to guide the menstrual blood to flow horizontally when it flows to the front and rear ends of the sanitary napkin body, thereby preventing the menstrual blood from leaking forward and backward. The second liquid guide groove is arranged vertically to guide the menstrual blood to flow vertically when it flows to the middle of the sanitary napkin body, thereby preventing the menstrual blood from leaking sideways and enhancing the structural strength and stability of the sanitary napkin body. Furthermore, the first liquid guide groove and the second liquid guide groove are arranged horizontally to guide the menstrual blood to flow vertically when it flows to the middle of the sanitary napkin body, thereby preventing the menstrual blood from leaking sideways and enhancing the structural strength and stability of the sanitary napkin body. The liquid groove is conductive, which can speed up the diffusion of menstrual blood and help keep the surface layer dry; further, the waist-shaped liquid guide groove allows menstrual blood to flow faster and more evenly, thereby improving absorption efficiency; further, the third liquid guide groove increases the flow path of menstrual blood, which can enhance protection and prevent menstrual blood from leaking from the edge; further, the U-shaped wrapping layer can enhance the overall structural strength and stability, provide certain support and protection, help prevent the absorption core from shifting, and avoid side leakage of menstrual blood; further; the breathable liquid guide holes can speed up the infiltration of menstrual blood and make the surface layer softer and more breathable.
