Disposable absorption object

Abstract

A disposable absorption object comprises an absorption body and a small coating material. The absorption body comprises a liquid-permeable face layer, a non-liquid-permeable bottom layer, and an absorption core located between the liquid-permeable face layer and the non-liquid-permeable bottom layer. A back adhesive layer is arranged on the side, close to a garment, of the non-liquid-permeable bottom layer of the absorption body. The small coating material temporarily protecting the back adhesive layer is arranged on the side, close to the garment, of the back adhesive layer. A longitudinal central protrusion is arranged on the surface, facing a body, in the longitudinal central area. A surface layer is formed by compositing non-liquid-permeable materials on the two sides of a liquid-permeable material. The non-liquid-permeable materials are of a C-shaped folding structure. Each non-liquid-permeable material comprises an upper folding edge, a lower folding edge and a folding mark edge. The folding mark edges are basically parallel to the longitudinal central line. Each folding mark edge is located on the transverse opposite inner sides and relative to the corresponding upper folding edge and the corresponding lower folding edge.

Description

technical field [0001] The present invention relates to a disposable absorbent article, in particular to a disposable absorbent article with improved leak-proof performance. Background technique [0002] Absorbent articles such as sanitary napkins, baby diapers, and adult incontinence products are all known products, and such disposable absorbent articles generally have a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent layer therebetween. core layer. The absorbent article is designed to absorb and retain the body wastes of the wearer, such as urine and menstrual blood, in the absorbent core. To prevent leakage of the wearer's body exudates from the absorbent article, the absorbent core must have sufficient absorbent capacity to contain and absorb body fluids. However, due to the different physiological characteristics of each person, and the limitations of the existing technology on disposable absorbent articles, when the excretion of the user i...

AI Technical Summary

Problems solved by technology

The leak-proof partition materials of the existing disposable absorbent articles generally adopt materials with hydrophobic properties (such as hydrophobic non-woven fabrics). In the use of disposable absorbent articles, the leak-proof partitions are generally in linear contact with the wearer's skin , the leak-proof partition will leave strangulation marks on the wearer

In addition, when the leak-proof partition is pressed down by the wearer's body when wearing it, the leak-proof partition cannot function normally, causing the leak-proof partition to fail, and body fluids leak from the disposable absorbent article and contaminate the wearer's clothing

In addition, bodily fluids often leak from the junction of the leak-resistant bulkhead and the liquid-permeable topsheet, contaminating the wearer's clothing and rendering the disposable absorbent article ineffective
