A baby diaper

Abstract

The invention relates to the field of toilet articles, particularly to a paper diaper for babies. The paper diaper comprises an outer cover, an absorption body, anti-leakage stop walls, leg elastic rubber bands and rear connection waistbands; the inner end of a fixed part of each anti-leakage stop wall is fixedly connected with the outer cover in an ultrasonic welding manner, and weld lines are regularly arranged along the length direction to form a first ultrasonic weld area; weld lines on an overlapped layer are arranged along the length direction to form a second ultrasonic weld area, a front ventilation passage running through along the length direction is formed between the first ultrasonic weld area and the second ultrasonic weld area of a front waist area, and a rear ventilation passage running through along the length direction is formed between the first ultrasonic weld area and the second ultrasonic weld area of a rear waist area. The paper diaper for the babies has advantages of low production cost, good application comfort and good ventilation performance along the length direction of the outer cover.

Description

technical field [0001] The invention relates to the field of hygienic products, in particular to a baby diaper. Background technique [0002] At present, the structure of baby diapers on the market mainly includes an outer cover, an absorber, a leak-proof retaining wall, elastic elastic bands on the legs and a rear connecting waistband. The outer cover includes a non-water-permeable outer layer and a water-permeable inner layer. The outer layer and the water-permeable inner layer are fixed by glue bonding along the edge of the absorber. The leak-proof retaining wall, the elastic elastic bands of the legs and the rear connection belt are all fixed on the outer cover by glue bonding. There is a magic buckle, and when in use, it is connected to the waistband to fit the diapers on the body. Such as figure 1 As shown, the leak-proof retaining wall is divided into a movable part b and a fixed part a from inside to outside. The middle part of the direction is separated from the ...

AI Technical Summary

Problems solved by technology

The deficiencies in existing baby diapers are: 1. When the diapers are used, there are only such figure 1 The position c between the two leak-proof retaining walls shown can be ventilated. Due to the fixed structure at the middle of the movable part b, the air passage of the diaper along the length direction is narrowed from bottom to top, so there is length direction ventilation The problem of poor performance; 2. The rear connection belt and the leak-proof retaining wall are all bonded to the outer cover by glue. In order to ensure the firmness of the connection, a large amount of glue is used. Too much glue can not only increase the production cost, but also Increased weight affects the comfort of use; 3. On the front and rear ends of the outer cover in the length direction, the non-water-permeable outer layer and the water-permeable inner layer are bonded by glue. In the actual assembly line production process, the impervious outer layer and the water-permeable inner layer The water-permeable inner layer enters the cutting process soon after the glue bonding process, that is, the glue between the impermeable outer layer and the water-permeable inner layer has not yet Complete cooling realizes the fixation of the two, so most diapers have partial separation between the impermeable outer layer and the water-permeable inner layer at the front and rear ends. Although it does not affect the use, the separated impermeable outer layer and water-permeable The protective inner layer is equivalent to openings at the front and rear ends of diapers, which may scratch the baby's skin and affect the comfort of use
