Description

Technical Field

[0001] The utility model relates to the field of sanitary products, in particular to a sanitary napkin with a leak-proof guard. Background Art

[0002] As an important sanitary product for women during menstruation, the performance and quality of sanitary napkins have a direct impact on women's quality of life and health. Side leakage is one of the common problems in the use of sanitary napkins, which not only brings inconvenience to users, but also may cause embarrassment and hygiene problems. Therefore, the anti-side leakage performance of sanitary napkins is one of the important indicators for evaluating its quality.

[0003] Currently, many sanitary napkin products on the market use a folded guard design. However, in actual use, consumers will press on the guard when wearing it, causing it to fold or collapse, making it easy for menstrual blood to leak sideways. In order to improve this problem, some sanitary napkins add elastic bands to the guard, so that the guard can be propped up with the support of the elastic band, forming a space that can accommodate menstrual blood, thereby reducing the risk of side leakage. However, this guard design will cause the elastic band to contact the inner thigh, which is easy to cause friction and cause discomfort to the user. The presence of the elastic band may also cause local blood accumulation, further increasing the discomfort. Utility Model Content
