Description

Flow stopping sanitary towel

Technical Field

The invention relates to the field of sanitary products, in particular to a flow-stopping sanitary towel.

Background

Conventional sanitary napkins provide the necessary sanitary protection for women during menstruation, and their primary function is to absorb and lock menstrual blood to keep the user dry and comfortable. However, prior sanitary napkins typically employ a planar absorbent layer, which can cause menstrual blood to flow or leak across the surface of the sanitary napkin, particularly when a significant amount of blood is discharged, which can easily cause side leakage.

In order to solve the above-mentioned technical problems, for example, an authorized bulletin number CN1219499C discloses a sanitary napkin, which specifically discloses that the sanitary napkin is provided with an inner layer, a liquid-permeable surface layer, an absorbent layer having liquid absorbing ability and located between the inner layer and the surface layer, at least a part of the area provided with the absorbent layer is used as a liquid receiving area; the liquid receiving area is provided with a longitudinal bulge part formed by hydrophilic materials and continuous along the front-back direction, and the bulge part is provided with a front area connected with the vaginal opening and a rear area connected with the buttocks. In the above-mentioned scheme, the bulge part is arranged in the liquid receiving area, and the bulge part can be closely contacted with the natal cleft of a female when in use, so that the aims of guiding menstrual blood and preventing side leakage are achieved. However, the bulge is continuous and longitudinally arranged along the front-back direction of the liquid-receiving region, so that the whole contact surface of the bulge is always in close contact with the body when in use; when the bulge part and the body are in a close contact state, air cannot freely flow, and after menstrual blood flows into the bulge part, the menstrual blood which is sticky and moist cannot be quickly air-dried, so that the menstrual blood is stuck on the skin, bacteria are easy to grow, skin allergy is caused, and discomfort is caused.

For another example, the grant publication CN101234056a discloses a sanitary napkin capable of preventing backward flow, which specifically discloses that the sanitary napkin has a main body, a pressing edge is formed at the periphery of the main body, a composite absorbing layer is arranged in the main body, a backward extending and drawable flow stopping belt is arranged on the main body, wherein the flow stopping belt is formed with an embossed absorber, and the absorber specifically has an equidistant structure; although the flow stopping belt on the sanitary napkin can penetrate into the femoral canal for guiding, in actual use, one end of the flow stopping belt needs to be pulled up and contacted with the skin, however, when one end of the flow stopping belt is in a pulled-up state, the flow stopping belt at one end is not contacted with the body, so that menstrual blood cannot permeate into the body through the flow stopping belt, and a better leakage-proof effect cannot be achieved.

Accordingly, there is a need for further improvements over the prior art.
