Paper diaper with front and back leak-proof three-dimensional enclosure

Abstract

A paper diaper with front and back leak-proof three-dimensional shield comprises a hydrophilic surface layer (1), a waterproof bottom layer, and a water-absorbing cotton core layer (2) arranged therebetween. The two lateral sides of the paper diaper are respectively provided with a lateral leak-proof three-dimensional shield (3), in which elastic bands (5) capable of longitudinally shrinking are arranged. The two longitudinal ends of the three-dimensional shield (3) are stuck with the hydrophilic surface layer (1) at the outside of the two longitudinal ends of the water-absorbing cotton core layer (2). Preferably, the shrinking length of the elastic bands (5) is greater than the longitudinal length of the water-absorbing cotton core layer (2).When the paper diaper is used, the elastic bands (5) are stretched to lift the waterproof bottom layer to form a certain height, thus the front end and the back end of the paper diaper generate good leak-proof effect. In addition, a water-absorbing layer (6) additionally arranged on the longitudinal ends of the water-absorbing cotton core layer (2) can realize more obvious leak-proof effect. An elastic waistband (7) is adhered on the back surface of the waterproof bottom layer to ensure more comfortable and close-fitting to wear.

Description

technical field [0001] The invention relates to a paper diaper, in particular to a paper diaper with good leak-proof effect. Background technique [0002] Traditional diapers, see figure 1 , its structure is roughly: the top is a hydrophilic surface layer 1 (generally using Lycra hydrophilic material), the bottom is a waterproof bottom layer (that is, the back of the diaper, generally using impermeable polyethylene material), and the middle is the absorbent cotton core layer (The dotted line part indicated by the number 2 in the figure is generally a mixed layer of fluff pulp and superabsorbent resin); it is cut and pressed into one piece, and a three-dimensional guard 3 is provided on each side of the diaper to prevent the amount of excrement. Leak from the side; In addition, a pair of Velcro 4 is provided on both sides of the rear end of the trouser body, so that the front and rear ends of the trouser body are glued and worn on the human body. The position where the long...

AI Technical Summary

Problems solved by technology

The position where the longitudinal ends of the three-dimensional enclosure of traditional diapers are bonded to the hydrophilic surface layer is above the absorbent cotton core layer, and the shrinkage length of the elastic in the three-dimensional enclosure is also smaller than the length of the cotton core layer (the shaded part in the figure indicates the three-dimensional The position where the enclosure is bonded, that is, area A) urine sometimes leaks to both sides and front and back along this part of the hydrophilic surface layer, causing clothing contamination
