Problems solved by technology

[0002] The surface of existing sanitary napkins is flat. During use, they are often deformed due to external forces, and liquid leakage occurs, which stains clothes and brings great troubles to women.
In order to prevent side leakage, the common sanitary napkins on the market generally use more absorbent absorbent materials, and set a number of longitudinal diversion grooves on the surface of the sanitary napkin to guide the liquid, although these anti-side leakage settings play a certain role. function, but it is only better than when it is still

Embodiment 1

[0027] See figure 1 The present invention discloses a sanitary napkin, which includes a back sheet 1, an absorbent core 2, a leak-proof portion 3, a top sheet 4 and an absorbent covering layer 5. Among them, the bottom end of the backsheet 1 is provided with an adhesive layer for bonding, so that the sanitary napkin can be bonded to the required position through the adhesive layer. In order to better absorb liquid, the sanitary napkin is designed to be a long strip. . In order to prevent the side leakage of the liquid absorbed in the absorbent core 2, the leakage preventing part 3 is wrapped on both sides of the absorbent core 2, and the material used for the leakage preventing part 3 can prevent the liquid from spreading. The top sheet 4 and the bottom sheet 1 are connected to form a cavity covering the absorbent core 2 and the leak-proof part 3. The entire absorbent core 2 and the leak-proof part 3 are completely covered with the top sheet 4 and the bottom sheet 1, so that th...

Embodiment 2

[0032] See figure 2 In another embodiment provided by the present invention, the structure of the sanitary napkin in this embodiment is similar to that of the sanitary napkin in the first embodiment, and the similarities are not repeated here, and only the differences are introduced.

[0033] In this embodiment, it is also specifically disclosed that the leakage preventing part 3 is provided between the top sheet 4 and the absorbent body coating layer 5. That is, the top sheet 4 is directly attached to the leak-proof part 3, the leak-proof part is attached to the absorbent body covering layer 5, and the absorbent body covering layer 5 is attached to the absorbent core 2 directly.

[0034] Furthermore, the present invention discloses that the leakproof part 3 includes a first leakproof part 31 and a second leakproof part 32; the first leakproof part 31 and the second leakproof part 32 are respectively arranged on both sides of the absorbent core 2 , And can cover both sides of the ...

Embodiment 3

[0042] See image 3 In the third embodiment of the present invention, the structure of the sanitary napkin in this embodiment is similar to that of the sanitary napkin in the second embodiment, and the similarities are not repeated here, and only the differences are introduced.

[0043] In this embodiment, it is specifically disclosed that the leakage preventing part 3 is provided between the absorbent body coating layer 5 and the absorbent core 2. That is, the inner side of the leakage prevention part 3 is directly bonded to the absorbent core 2, and the outer side of the leakage prevention part 3 is directly bonded to the absorbent body coating layer 5.

[0044] When using the sanitary napkin provided by the present invention, the sanitary napkin is fixed to a desired position through the adhesive layer of the backsheet 1. Since the sanitary napkin is provided with the first leakproof part 31 and the second leakproof part 32 on both sides of the absorbent core 2 to block the diff...

Abstract

The invention discloses a sanitary towel which comprises a base piece and an absorption core. The bottom end of the base piece is provided with an adhesion layer having an adhesion effect. The sanitary towel further comprises anti-leaking parts capable of preventing liquid from diffusing, a top piece and an absorber coating layer, wherein the anti-leaking parts wrap the two sides of the absorption core; the top piece is connected with the base piece to form a cavity wrapping the absorption core and the anti-leaking parts; and the absorber coating layer is arranged in the cavity formed by the top piece and the base piece and wraps the absorption core. When the sanitary towel is used, the sanitary towel is fixed to a required position through the adhesion layer of the base piece. Since the anti-leaking parts capable of preventing the liquid from diffusing are arranged on the two sides of the absorption core, liquid side leakage can be effectively avoided; the top piece and the base piece wrap the whole absorption core and the anti-leaking parts, so that the top piece is in direct contact with the human body, and use comfort of the sanitary towel is improved. In addition, through the arrangement of the absorber coating layer, the absorption core can be effectively fixed.

Description

Technical field [0001] The invention relates to the technical field of menstrual supplies, in particular to a sanitary napkin.
