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

Abstract

The invention relates to a paper diaper, in particular to a paper diaper with good leak-proof effect. The paper diaper comprises a hydrophilic surface layer and a waterproof bottom layer, an absorbent cotton core layer is arranged between the hydrophilic surface layer and the waterproof bottom layer, the hydrophilic surface layer and the waterproof bottom layer are bonded together at the outside of the two longitudinal ends of the absorbent cotton core layer, the two sides of the paper diaper are respectively provided with a lateral leak-proof three-dimensional enclosure in which a rubber string capable of longitudinally shrinking is arranged, the two longitudinal ends of the three-dimensional enclosure are bonded with the hydrophilic surface layer, and the bonding positions are arranged outside the two longitudinal ends of the absorbent cotton core layer. The preferential scheme of the invention is as follows: the shrinking length of the rubber string in the three-dimensional enclosure of the paper diaper is larger than the longitudinal length of the absorbent cotton core layer. When the paper diaper is used, the rubber string is 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, an absorbent layer additionally arranged on the longitudinal end of the absorbent cotton core layer can realize more obvious leak-proof effect, and an elastic waistline is bonded on the back surface of the waterproof bottom layer to ensure more comfortable and closed-fit wearing.

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...

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
