Description

Technical Field

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

[0002] Existing sanitary napkins generally include a liquid permeable surface layer, a liquid impermeable bottom layer and an absorbent layer located between the liquid permeable surface layer and the liquid impermeable bottom layer. The absorbent layer is usually formed of a fluff pulp polymer material and is folded in three or in half to form a small package. The sanitary napkin is thick and has poor air permeability, and is less comfortable to use.

[0003] Chinese patent application number: 202010807663.X discloses a portable sanitary napkin, comprising a skin-friendly surface layer, an absorbent core and a liquid-impermeable bottom layer arranged on the lower surface of the absorbent core, the absorbent core comprising an absorbent core body and a convex structure arranged in the middle of the upper surface of the absorbent core body, the convex structure having a width of 25mm-45mm, a length of 60mm-120mm, and a thickness of 2-5mm, the absorbent core body and the convex structure are both made of polyurethane foam, the lower surface of the liquid-impermeable bottom layer is provided with a transverse adhesive, the sanitary napkin is wrapped with a release film, the sanitary napkin wrapped with the release paper is flattened and curled upward along the length direction of the absorbent core to form a cylinder, and fixed with an easy-tear sticker. Made of polyurethane foam, the sanitary napkin has good compressibility and recovery properties. After being flattened and rolled up, it is cylindrical. Compared with the existing sheet-shaped ones, it has the characteristics of small size and strong concealment, which is convenient for users to carry. After being unfolded, it will not produce wrinkles, and it has good air permeability, no layers or lumps, and the comfort of use is greatly improved.

[0004] The absorption speed of the absorbent core made of polyurethane foam can be greatly improved, but the effect of extravasation diversion is reduced, making it easy for liquids such as menstrual fluid to gather in the middle, resulting in relatively poor comfort during long-term use.
