Problems solved by technology

[0007] In addition, when pressure from the side is applied to the crotch of the underwear due to the compression of the thigh, the leak-proof wall is easily deformed due to the direct action of the above-mentioned pressure on the base of the leak-proof wall near the edge of the crotch of the underwear. A gap is easily formed between the leak-proof wall and the skin, and the above-mentioned pocket-shaped concave portion is more likely to be deformed, thereby easily reducing the liquid leak-proof effect

Embodiment Construction

[0025] Fig. 1 is a plan view showing the sanitary napkin of the present invention, showing the state when the leak-proof layer is removed from the left half of the sanitary napkin bordered by the central line O-O. Fig. 2 is a sectional view taken along line II-II of Fig. 1 . Fig. 3 is a partial sectional view when the sanitary napkin of the present invention is attached to underwear. Fig. 4 is a half sectional view showing another embodiment of the sanitary napkin of the present invention. The sanitary napkin shown in Fig. 1 and Fig. 2 is a sanitary napkin which is attached to the inner surface of the crotch of the panties (external mounting body) by women during menstruation.

[0026] The planar shape of the sanitary napkin has a substantially arc-shaped front edge portion 2 and a similarly arc-shaped rear edge portion 3, the left edge portion 4 and the right edge portion 5 are curved, and the left edge portion 4 and the right edge The distance between the portions 5, that ...

Abstract

The object of the present invention is to provide a sanitary napkin which is easily arranged in the center part of a crotch part in underwear without giving a deformation force to the base part of a leakage preventing part when a force is added from side parts. The solution of the present invention for realizing the object is that leakage preventing parts 15a and 16a are formed on the surface of a surface sheet 12 along joint parts 20, 20. Extending parts 15b and 16b are arranged at the outer sides of the leakage preventing parts 15a and 16a. A flexible area M is formed between internal reinforcing sheets 12c and 12d, internal reinforcing sheets 18a and 18b and reinforcing sheets 24 and 25 in the extending parts 15b and 16b so that wing parts 6 and 7 are easily bent from the flexible area M. Besides, a part with the arranged internal reinforcing sheets is made to be a buffering area D so that the force is not directly given from the side parts in the case of arrangement with respect to the leakage preventing parts 15a and 16a.

Description

technical field [0001] The present invention relates to a sanitary napkin, which is provided with a leak-proof portion extending in the longitudinal direction on both sides of the surface, and at least a part of the protruding portion extending outside the leak-proof portion is bent toward the back layer side. And fixed on the underwear. Background technique [0002] The liquid-absorbing layer of the sanitary napkin reliably absorbs menstrual blood during use and prevents menstrual blood from leaking out of the sanitary napkin. In the conventional sanitary napkins, the sanitary napkins are deformed by external force due to movement, and when the above-mentioned deformation occurs in a state where the absorbing capacity cannot be fully exerted, there is often a problem that the menstrual blood cannot be reliably absorbed and the liquid leaks to contaminate the clothes. Especially when the user is walking, standing up, sitting or exercising, the part of the leg between the th...
