Description

Technical Field

[0001] The utility model relates to the technical field of disposable absorbent articles, and particularly relates to a disposable absorbent pant with a double-layer three-dimensional side edge. Background Art

[0002] Disposable absorbent pants include diapers, pull-up pants, and menstrual pants. There is a problem that the three-dimensional side edges rub the thighs during wearing. The current three-dimensional side edges are composed of water-repellent non-woven fabric and elastic filaments. The lower edge of the water-repellent non-woven fabric is fixed on the absorbent pant. The upper edge of the water-repellent non-woven fabric is folded and the elastic filaments are wrapped inside the fold. The elastic force of the elastic filaments makes the water-repellent non-woven fabric stand up to prevent liquid side leakage. Since the elastic filaments are arranged along the upper edge of the three-dimensional side edge, the elastic filaments will directly rub and even press on the root of the thigh, causing the root of the thigh to turn red and itchy, affecting the wearing comfort.

[0003] To solve the above problems, this case is thus generated. Summary of the Utility Model

[0004] Therefore, in view of the above problems, the utility model provides a disposable absorbent pant with a double-layer three-dimensional side edge.

[0005] To solve the above technical problems, the solution adopted by the utility model is: a disposable absorbent pant with a double-layer three-dimensional side edge, including a liquid-permeable surface layer, an absorbent layer, an elastic layer, and an impermeable bottom layer. The liquid-permeable surface layer is provided with three-dimensional side edges on both left and right sides of the absorbent layer.

[0006] The three-dimensional side edge includes a water-repellent layer and elastic filaments. The lower edge of the water-repellent layer is arranged on the liquid-permeable surface layer in the front-back direction. The upper edge of the water-repellent layer is first folded inward to form a first folded part for wrapping the elastic filaments, and then folded outward along the outer contour of the first folded part to the outside of the water-repellent layer to form a second folded part. The elastic filaments are adhesively arranged in the front-back direction in the first folded part. A first hollow part is formed by setting a distance between the elastic filaments and the top of the first folded part. The distance between the elastic filaments and the top of the first folded part is 2-5 mm. A second hollow part is formed by setting a distance between the top of the second folded part and the top of the first folded part.

[0007] Further improvement is: a flexible strip adapted to the shape deformation of the root of the thigh and fitting the skin is movably arranged in the first hollow part and / or the second hollow part, and the length of the flexible strip is not longer than the length after the elastic filaments are contracted.

[0008] Further improvement is: the outer diameter of the flexible strip is 2-4 mm.

[0009] Further improvement is: the flexible strip is a cotton rope or a sponge strip or a non-woven fabric roll strip.

[0010] Further improvement: The lower edge of the water-repellent layer extends and turns over along the side edge of the liquid-permeable surface layer towards the liquid-impermeable bottom layer and is arranged on the outer surface of the liquid-impermeable bottom layer.

[0011] Further improvement: The number of the elastic wires is one, two or three.

[0012] Further improvement: The distance between the elastic wire and the top of the first folding part is 4 mm.

[0013] Further improvement: The water-repellent layer is a water-repellent non-woven fabric, or a plastic water-repellent film layer, or a composite layer of non-woven fabric and plastic water-repellent film.

[0014] Further improvement: The elastic wire is a rubber band.

[0015] By adopting the foregoing technical solutions, the beneficial effects of the utility model are as follows:

[0016] In this case, the upper end of the three-dimensional spacer edge is a double-layer structure. By lowering the rubber band, the distance between the rubber band and the upper edge of the spacer is increased, avoiding the direct strangulation and friction between the rubber band and the thigh skin. The first hollow part and the second hollow part are used to increase the standing height of the three-dimensional spacer edge, ensuring the anti-side leakage effect of the three-dimensional spacer edge. At the same time, the rubber band and the skin are separated by two layers, avoiding the rubber band from strangling and rubbing the skin, and improving the wearing comfort of the disposable absorbent pants.

[0017] Further beneficial effects are: The flexible strips filled in the first hollow part and / or the second hollow part can well conform to the shape of the thigh root and deform under the extrusion of the thigh root, conform to the skin, provide a soft feeling for the skin, and at the same time prevent the strangulation and friction of the rubber band, greatly improving the wearing comfort of the absorbent pants, and can also make the three-dimensional spacer edge stand upright and enhance the anti-side leakage effect.

[0018] Further beneficial effects are: The flexible strips can directly use finished cotton strips or sponge strips, or can use non-woven fabric roll strips rolled from non-woven fabric scraps generated during the processing of disposable absorbent pants, so as to realize the reuse of waste materials and reduce the material cost.

[0019] Further beneficial effects are: The lower edge of the water-repellent layer turns over to the outer surface of the liquid-impermeable bottom layer and is glued and fixed on the outer surface of the liquid-impermeable bottom layer. The water-repellent layer wraps and seals the side edges of the liquid-impermeable bottom layer and the liquid-permeable surface layer, improving the anti-side leakage effect of the disposable absorbent pants.
