Problems solved by technology

In addition, because the tension design of the free end of the double leak-proof partition of the inner and outer layers is not optimal, when wearing a disposable absorbent product, the double leak-proof partition will collapse due to the extrusion of the corresponding parts of the human body, which will lead to When the disposable absorbent product receives body fluid, the body fluid discharged on the surface layer of the disposable absorbent product will leak through the inner leak-proof partition to the outer leak-proof partition. This kind of leakage is relatively large, which is also undesirable. of
The main reasons for the above-mentioned large leakage are: fit problems, that is, the dimensions of disposable absorbent products such as the height of the leak-proof partition and the width of the crotch are unreasonably designed; the anti-deformation of the leak-proof partition is poor, that is, the leak-proof partition The reason why the free end elastic part cannot make the leak-proof partition stand up effectively, etc.
Moreover, the inner and outer leak-proof partitions of the prior art are either formed by folding the surface layer itself, or are formed on the surface layer by a hydrophilic fabric layer. In the area between the inner and outer leak-proof partitions, body fluids will leak from the front and back along the junction of the inner and outer leak-proof partitions, or leak outward through the outer leak-proof partition, so that the leakage cannot be effectively prevented

Embodiment 1

[0025] The disposable absorbent product provided by the present invention mainly comprises a liquid-permeable surface layer 2, a liquid-impermeable bottom layer 4, and an absorbent core 3 which absorbs and holds body fluids placed between the above-mentioned two. Left and right leak-proof partitions 5 extending in the longitudinal direction, wherein the leak-proof partition 5 includes an inner layer leak-proof partition 51 and an outer layer leak-proof partition 52, each leak-proof partition includes a base and is connected to the base and is located at the base. The upper part of the free section. Wherein the disposable absorbent article may also comprise other layers in the art, such as an acquisition layer above the absorbent core 3 and below the topsheet 2, a surge layer, a distribution layer, a diffusion layer, a formation layer at the bottom of the absorbent core, Diffusion layers, etc., and may also include fabric layers wrapping the absorbent core, superabsorbent parti...

Embodiment 2

[0031] Such as Image 6 As shown, the left and right leak-proof partition materials of the disposable absorbent product are first laid parallel to the surface layer 2, the bottom layer 4, and the absorbent core 3, and its longitudinal boundary can exceed the longitudinal boundary of the surface layer 2 or the absorbent core 3, and simultaneously The longitudinal boundary of the bottom layer 4 is even, and the material extends upwards and bends inwards to form an outer leakage-proof partition 52 with a completely overlapping part of the material, and then the material extends parallel to the surface layer 2, the bottom layer 4, and the absorbent core 3 , and then extend upwards and bend inwards to form a portion with overlapping materials to form the inner leakage-proof partition 51 . The base of the inner leak-proof partition 51 is bonded to the surface layer, and the base of the outer leak-proof partition 52 is bonded to the bottom layer 4 . Because the surface material has ...

Embodiment 3

[0034] Such as Figure 7 Shown is another embodiment of the left and right leak-proof partitions of the disposable absorbent product of the present invention. The leak-proof partition material of the disposable absorbent product is first laid flat parallel to the surface layer 2, the bottom layer 4, and the absorbent core 3, and its longitudinal The upper boundary can exceed the longitudinal boundary of the surface layer 2 or the absorbent core 3, and at the same time be flush with the longitudinal boundary of the bottom layer 4, and the material is extended upward and inwardly bent to form a part with materials completely overlapped to form an outer leak-proof partition 52, and then the material extends parallel to the surface layer 2, the bottom layer 4, and the absorbent core 3, and then extends upwards and bends inwards to form joints on the surface layer material to form an inner leak-proof partition 51.

Abstract

The invention discloses a disposable absorption product with double leakproof isolation boundary, which mainly comprises a liquid-permeability surface layer, a liquid-tight bottom layer and an absorption surface, wherein the two sides of the width direction of the absorption product are provided with leakproof isolation boundaries which are extended along lengthways direction, the leakproof isolation boundary at each side comprises an inner-layer leakproof isolation boundary and an outer-layer leakproof isolation boundary, each leakproof isolation boundary comprises a base part and a free part which is connected with the base part and is positioned at the upper end of the base part, the base parts of the outer-layer leakproof isolation boundaries can be connected with the surface layers or the bottom layers, and the base parts of the inner-layer leakproof isolation boundaries are connected with the surface layers. The inner-layer leakproof isolation boundaries and the outer-layer leakproof isolation boundaries are formed into a whole, the outer-layer leakproof isolation boundaries have completely-overlapped material parts, and the inner-layer leakproof isolation boundaries have partially-overlapped material parts. The base parts of the inner-layer leakproof isolation boundaries are distant from the base parts of the outer-layer leakproof isolation boundaries. The elastic expansion range of elastic expansion parts at the free parts of the leakproof isolation boundaries are adjusted, so that front leakproof isolation boundaries and back leakproof isolation boundaries are formed into an opening of a bag facing to a lengthways middle opening, and front leakage and back leakage can be reduced. The product also uses an external elastic waistline and left and right elastic magnetic paste.

Description

technical field [0001] The present invention relates to a disposable absorbent product with double leak-proof partitions, more specifically, the present invention relates to a disposable absorbent product with double leak-proof partitions that can stand up effectively to provide better leak-proof effect . Background technique [0002] The CN2162945Y utility model patent granted to Japan Youni Jiaomei Co., Ltd. discloses a disposable diaper, wherein the two sides of the diaper in the longitudinal direction are provided with corresponding first flaps and second flaps separated transversely. The first flap and the second flap form a double leak-proof bulkhead. However, the free ends of the above-mentioned flaps are not provided with elastic members or members that allow the flaps to stand up effectively, so they collapse under the weight of the body during use, and cannot effectively double leak-proof effects. [0003] The invention patent of CN1181004A submitted by Proctor a...
