AI Technical Summary
Existing diapers are prone to leakage from the front and back when the baby is lying on their stomach or back, especially when the baby defecates. The absorption efficiency of the absorbent core is affected by compression, causing urine and feces to easily leak from the front and back of the diaper.
Leak-proof layers are set at the front and rear ends of the absorbent core to form a leak-proof pocket with the opening facing the middle of the absorbent core. Elastic strips are set on the sides of the leak-proof pocket. The elastic leg circumference is used to stretch the opening of the leak-proof pocket to prevent urine and feces from leaking out from the front and back.
It effectively prevents urine and feces from leaking from the front and back of the diaper, improves absorption efficiency, reduces stuffiness, simplifies production and processing, and reduces costs.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to one -time absorption trousers technical field, especially in kind of pull -up pants with prevent before and after leak function. BACKGROUND
[0002] Current urine pants all pay attention to prevent crotch part side leak, but when baby is on the stomach or lies, urine and excrement not only will side leak but also easily leak out along the front end or rear end of urine pants. When baby is on the stomach, the belly presses the front end of urine pants and influences the absorption efficiency of the front end of the absorption core, and when lies, the buttocks press the rear end of urine pants and influence the absorption efficiency of the rear end of the absorption core, so that urine and excrement will appear before leak or after leak. Especially when baby defecates, excrement is easy to be squeezed out of urine pants along the front and rear direction of the absorption core.
[0003] In order to solve the above problem, the case is generated. CONTENT OF THE UTILITY MODEL
[0004] Therefore, in view of the above problems, the utility model provides a kind of pull -up pants with prevent before and after leak function for solving urine pants front and rear leak problem.
[0005] To solve the above technical problems, the utility model takes the following solution: a kind of pull -up pants with prevent before and after leak function, including outer surface layer, inner surface layer, absorption core, elastic leg, the inner surface layer is covered and is arranged on the absorption core, the absorption core with the inner surface layer is arranged on the inner surface of the outer surface layer, the elastic leg is vertically arranged in the left and right sides of the absorption core and lower edge is glued between the absorption core and the outer surface layer, the front end and / or rear end of the absorption core is covered and is arranged with leakage prevention layer, three sides of the leakage prevention layer are glued on the outer surface layer, form the leakage prevention pocket with the opening towards the middle part of the absorption core, the elastic leg end is covered in the leakage prevention pocket, the leakage prevention layer is adapted to the left and right stretching or contraction of the outer surface layer.
[0006] Further improvement is that: at least one elastic strip perpendicular to the elastic leg is arranged on the edge of the side of the opening of the leakage prevention layer.
[0007] Further improvement is that: the leakage prevention layer is lengthened by the front end and / or rear end of the outer surface layer and is fixed on the inner surface of the outer surface layer by folding.
[0008] Further improvement is that: the outer surface layer includes outer layer and inner layer, and the leakage prevention layer is lengthened by the front end and / or rear end of the outer layer or inner layer and is formed by being fixed on the inner layer by folding.
[0009] Further improvement is that: the front end or rear end of the leakage prevention layer exceeds the front end or rear end of the outer surface layer and is fixed on the outer surface of the outer surface layer by folding.
[0010] Further improvement is that the material of the leakage-proof layer is water-repellent non-woven fabric.
[0011] Further improvement is that the elastic strip is spandex filament.
[0012] By adopting the foregoing technical scheme, the utility model has the beneficial effects that:
[0013] In the case, the leakage-proof pocket with the opening facing the middle part of the absorbent core is formed by fixing the leakage-proof layer on the front and rear ends of the absorbent core, and the leakage-proof pocket hinders the front and rear leakage of urine or feces. The elastic leg bands on the left and right sides of the leakage-proof pocket are covered by the leakage-proof pocket, and when the pull-ups are worn, the spandex filaments on the elastic leg bands are stretched, the elastic leg bands are erected, the opening of the leakage-proof pocket is lifted, and the gap for liquid is reserved between the opening of the leakage-proof pocket and the absorbent core, so that the urine and feces can enter the leakage-proof pocket.
[0014] Further beneficial effect is that the elastic strip on the opening side of the leakage-proof pocket is stretched horizontally when the pull-ups are worn, and the opening of the leakage-proof pocket is further opened, which is beneficial to improve the leakage-proof effect of the leakage-proof pocket.
[0015] Further beneficial effect is that the leakage-proof pocket can be formed in various ways, and the leakage-proof layer can be additionally provided or directly made of the outer layer.
[0016] The forming mode of directly lengthening and folding the outer layer or the inner layer of the outer layer of the outer layer can only need to widen the raw material and set the folding plate on both sides of the conveying line, without the need to change the existing processing equipment, so as to simplify the production and optimize the processing cost.
[0017] Only the outer layer or the inner layer of the outer layer is used to form the leakage-proof pocket, which can reduce the thickness of the front and rear waist parts and reduce the stuffy feeling. BRIEF DESCRIPTION OF DRAWINGS
[0018] Figure 1 is a three-dimensional structure schematic diagram of the pull-ups with the front and rear leakage-proof function according to an embodiment of the utility model. DETAILED DESCRIPTION
[0019] The utility model will be further described in combination with the drawings and specific embodiments. Embodiment one:
[0020] Reference Figure 1This utility model discloses a pull-up pant with anti-leakage function, including an outer layer 10, an inner layer 11, an absorbent core, and elastic leg wraps 13. The inner layer 11 is made of hydrophilic non-woven fabric. The absorbent core and elastic leg wraps 13 are existing technologies and will not be described in detail here. The inner layer 11 covers the upper and lower surfaces of the absorbent core on both sides. The absorbent core and the inner layer 11 are bonded to the inner surface of the outer layer 10. The elastic leg wraps 13 are erected on the left and right sides of the absorbent core and their lower edges are bonded between the absorbent core and the outer layer 10. A plurality of elastic threads 14, which are spandex threads, are provided on the front waist and back waist of the outer layer 10. The left and right sides of the front waist and the left and right sides of the back waist of the outer layer 10 are ultrasonically welded. The outer layer 10 includes an outer layer 101 and an inner layer 102. Both the outer layer 101 and the inner layer 102 are made of water-repellent non-woven fabric.
