[0018] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0019] Please refer to Figures 1-4, the present utility model provides a pull-up diaper with good leak-proof effect, which includes an intermediate layer 1, a front waist 2, a rear waist 3, an absorption layer 4, a lace 5, leak-proof side barriers 6, a leak-proof front barrier 7 and a leak-proof rear barrier 8. The front side of the intermediate layer 1 is stitched with the front waist 2, and the rear side of the intermediate layer 1 is stitched with the rear waist 3. The left and right sides of the front waist 2 and the rear waist 3 are bonded by hot melt adhesive. The front waist 2 and the rear waist 3 have folding areas, and the front waist 2 and the rear waist 3 can be horizontally stretched through the elastic rubber bands stitched inside, so as to be easily fitted to the waist of infants. An absorption layer 4 capable of absorbing liquid is arranged in the middle of the intermediate layer 1. Wave-shaped laces 5 are connected to both left and right sides of the intermediate layer 1, which can make the whole product more beautiful. Two groups of leak-proof side barriers 6 are symmetrically bonded to the surface of the intermediate layer 1 by hot melt adhesive. Both groups of leak-proof side barriers 6 have folding areas, and both groups of leak-proof side barriers 6 can be longitudinally stretched through the elastic rubber bands arranged inside. The elastic rubber bands can pull the two groups of leak-proof side barriers 6 to turn up and stand upright, and the absorption layer 4 is located between the two groups of leak-proof side barriers 6. The rear side of the front waist 2 is press-bonded with a leak-proof front barrier 7 by hot melt adhesive, and the front side of the rear waist 3 is press-bonded with a leak-proof rear barrier 8 by hot melt adhesive. The leak-proof front barrier 7 and the leak-proof rear barrier 8 are of the same size, and elastic ropes 9 are equally spaced and stitched inside the leak-proof front barrier 7 and the leak-proof rear barrier 8, which can make the leak-proof front barrier 7 and the leak-proof rear barrier 8 have stronger ductility, increase the storage space, and both the absorption layer 4 and the leak-proof side barriers 6 are located between the leak-proof front barrier 7 and the leak-proof rear barrier 8, so that the two groups of leak-proof side barriers 6, the leak-proof front barrier 7 and the leak-proof rear barrier 8 form an enclosed structure around the absorption layer 4, and a multi-directional leak-proof effect can be achieved. The leak-proof front barrier 7 and the leak-proof rear barrier 8 are integrally arranged in a split manner and are press-bonded by hot melt adhesive without stitching. The installation process is simple, the cost is saved, and both the two groups of leak-proof side barriers 6, the leak-proof front barrier 7 and the leak-proof rear barrier 8 are liquid-impermeable, which can effectively isolate liquid excrement and prevent the liquid excrement from seeping into the front waist 2 and the rear waist 3, causing discomfort to infants during wearing.

[0020] Among them, the middle part of the rear side of the leak-proof front barrier 7 has a non-adhesive area, and the middle part of the front side of the leak-proof rear barrier 8 has a non-adhesive area. Both the leak-proof front barrier 7 and the leak-proof rear barrier 8 can be turned up to form a blocking structure for preventing front and rear leakage, so as to prevent excrement from sliding down in the front and rear directions when taking off the product.

[0021] Among them, both inner sides of the two groups of leak-proof side barriers 6 have non-adhesive areas, and the two groups of leak-proof side barriers 6 can be turned to both sides to form a side leakage prevention blocking structure, so as to prevent excrement from sliding down in the left and right directions when taking off the product.

[0022] Specifically, first separate the front waist part 2 and the rear waist part 3, then insert the legs of the infant into the front waist part 2 and the rear waist part 3 and pull them out from both sides of the middle layer 1, so that the absorbent layer 4 is in contact with the crotch of the infant. The front waist part 2 and the rear waist part 3 can fasten the product to the waist of the infant through the elastic rubber bands arranged inside. The absorbent layer 4 can absorb urine. The leak-proof side flaps 6 will contract and stand up through the elastic rubber bands inside and be in contact with the legs of the infant, which can prevent side leakage of excrement. When taking off the product, the leak-proof front flap 7 and the leak-proof rear flap 8 can intercept the excrement remaining on the absorbent layer and prevent the excrement from slipping to the ground.
