Description

sanitary napkin

technical field

The present invention relates to a kind of sanitary product for women, especially relates to a kind of sanitary napkin.

Background technique

Referring to Fig. 1, the sanitary napkin 1 disclosed in the Chinese Taiwan Announcement No. I272094 Patent of Invention, the sanitary napkin 1 includes an absorbent layer 11 and two leak-proof side edges 12, and also includes an absorbent layer 11 protruding from the absorbent layer 11. Auxiliary absorber 13 on top. The auxiliary absorbent body 13 can fit in the user's pudendum and groin more closely, and reduce the chance of menstrual blood flowing backward along the groin. However, if the user is in a lying position or has a change in posture, the auxiliary absorbent body 13 still cannot completely fit the user's pudendum, and it has no positioning effect, and it is easy to reduce the fit due to the change of the user's posture. degree, and the effect of the auxiliary absorber 13 is greatly reduced.

In order to overcome the above-mentioned shortcomings, the inventor of the present case has developed a sanitary napkin 1 as shown in Figure 2, which is disclosed in the Taiwan Patent No. I466663. This sanitary napkin 1 includes an absorbent layer 14, and a soft and water-absorbent material The flow guide layer 15 is made and arranged on the absorbing layer 14 . The flow guide layer 15 includes two side wall parts 151 extending from front to back and spaced apart from each other left and right, a central part 152 connected to the side wall parts 151 and spaced up and down from the absorbing layer 14, and a central part 152 formed by the central part. The rear pull portion 153 extending backward from the portion 152 .

Utilize the side wall portion 151 that gradually increases from front to back, so that the central portion 152 and the rear lifting portion 153 also gradually extend backward and upward, so as to improve the fitting degree with the user's genitals, and the matching part protrudes from the absorption The rear pull portion 153 outside the layer 14 can be clamped between the absorbent layer 14 and the user's body, which not only assists in positioning the absorbent layer 14 to prevent the flow guide layer 14 from shifting, but also absorbs backward spillage. Menstrual bleeding.

However, the flow guiding layer 15 has only one rear pulling portion 153 , so there is still room for improvement in the ability of the flow guiding layer 15 to absorb or guide menstrual blood overflowing backward.
