Description

Technical Field

[0001] The invention relates to a sanitary product, in particular to a sanitary napkin. Background Art

[0002] The applicant applied for a design patent for a non-woven fabric (wing surface layer) for sanitary napkins at an earlier time (application number: 2023302026843), which has two intertwined ink lines, and the ink lines are treated with water repellent. During the production process, it is necessary to use them as wing surface layers and fix them on both sides of the sanitary napkin by bonding. Because the ink lines have been specially treated, they are not adhered by the adhesive, that is, the ink lines and the surface of the sanitary napkin are in a separated state, resulting in the absorption of liquid reaching a certain level (especially in the early stage of women's menstrual period, the amount of menstrual blood When the ink line is larger, the sanitary napkin as a whole absorbs water and expands, resulting in a tear between the ink line and the surface of the sanitary napkin, so that menstrual blood directly penetrates to both sides and causes side leakage. The central blank position where the ink lines intersect will also form a sticking connection relationship with the surface of the sanitary napkin when sticking, but the ink line isolates this position from the outer sticking part to form a dot-shaped sticking point. The applicant found that the sticking point was not interconnected with the outer sticking part, resulting in the same when a certain amount of liquid is absorbed. The sticking point will be directly separated from the surface of the sanitary napkin because the sanitary napkin expands after absorbing water. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a side leakage-proof sanitary napkin.

[0004] The technical solution adopted by the present invention to solve its technical problem is: A side leakage prevention sanitary napkin comprises a sanitary napkin body, with wings symmetrically attached to both sides of the middle of the sanitary napkin body, the top surface of the wings being provided with a plurality of spaced-apart water-repellent patterns, a non-water-repellent portion being provided between two adjacent water-repellent patterns; a folded portion is folded at least once on one side of the wings close to the sanitary napkin body, the bottom surface of the folded portion being attached to the surface of the sanitary napkin body.

[0005] The width of the non-water-repellent portion is 2 mm to 10 mm.

[0006] The folding portion is composed of a first folding edge, a second folding edge and a third folding edge from top to bottom, the inner edge of the wing is folded 180° from bottom to outside to form the first folding edge, the outer edge of the first folding edge is folded 180° from bottom to inside to form the second folding edge, the inner edge of the second folding edge is folded 180° from bottom to outside to form the third folding edge, and the bottom surface of the third folding edge is adhered to the surface of the sanitary napkin body.

[0007] The width of the second folding edge is half of the width of the first folding edge, and the width of the third folding edge is the same as the width of the second folding edge.

[0008] The width of the third folded edge is 0.5 mm-2 mm.

[0009] The beneficial effects of the present invention are: 1. The present invention has wings symmetrically attached to both sides of the middle part of the sanitary napkin body, and the top surface of the wings is provided with a plurality of spaced water-repellent patterns, and a non-water-repellent portion is provided between two adjacent water-repellent patterns. During bonding, the non-water-repellent portion and the positions on both sides of the water-repellent pattern are bonded to the surface of the sanitary napkin body, so that the bonding parts of the wings form a whole, can cooperate with each other to increase the bonding strength between the wings and the surface of the sanitary napkin body, and avoid cracking, which leads to side leakage.

[0010] 2. The side of the wing close to the sanitary napkin body is folded with at least one folding portion, and the bottom surface of the folding portion is adhered to the surface of the sanitary napkin body. When the wing is folded outward and attached to the bottom surface of the crotch, the folding portion is naturally turned up to form a retaining wall, thereby improving the effect of preventing side leakage. At the same time, after folding, the edge of the folding portion is more comfortable to wear than the raw edge formed by direct cutting. BRIEF DESCRIPTION OF THE DRAWINGS
