Description

A comfortable two-piece diaper

technical field

The utility model relates to the technical field of diapers, in particular to a comfortable two-piece diaper.

Background technique

With the increase of my country's per capita purchasing power and the change of the concept of parenting, the baby diaper market has maintained a momentum of rapid growth. With the continuous increase of the market share of diapers, the competition has become increasingly fierce. In the past few years, the product has changed from three-piece to two-piece, and the structure has been continuously upgraded.

Among them, the three-piece diaper is the product chosen by many manufacturers at the earliest stage. It is mainly composed of three parts: one part is a composite absorber, the other two parts are two pieces of elastic waist non-woven fabrics on the front and back, and the elastic waist on the front and the back. Elastic waist is split. Although the three-piece diaper has low cost, simple structure, and mature manufacturing technology, the lateral side of the elastic waist near the crotch is generally horizontal and straight, which is not suitable for the body's shape. When worn, it fits poorly with the human body and is comfortable. The sex is not very good, because the fit of the human body is not tight, it is easy to leak urine.

The two-piece diaper is mainly divided into two parts, one part is a composite absorbent body, the other part is bonded with the whole waist cloth inside and outside, and then the leg holes of different sizes are cut out by an O cutter, and the legs are bonded through the side. The stretching of the tendons is more in line with the leg structure of the human body, the fit is tighter, and the 360° surround fits better.

However, since the elastic waists at the front and back of the two-piece diaper are set as a whole, in order to ensure a tight fit with the waist and abdomen of the infant when worn, the waist is often provided with multiple elastic bands arranged in parallel. Such a structural setting It makes the feeling of tightness stronger when wearing, and long-term use will cause strangle marks or red marks on the abdomen of infants and young children. Not only is the comfort poor, but it will also have a certain impact on the digestive system in severe cases.

The prior art discloses a comfortable diaper, which consists of an elastic waist, an elastic leg and an absorbent trouser body. The elastic waist comprises a front elastic waist and a rear elastic waist. The bottom film, the front elastic waist and the back elastic waist are composed of the inner waist non-woven fabric and the outer waist non-woven fabric, which are bonded with elastic waist. It is made of bonded non-woven fabric on the outside, and the non-woven fabric is folded up and bonded to the absorbent core. There is an elastic band at the folded up part of the non-woven fabric. Although the elastic waist of the comfortable diaper depends on the degree of fit between the baby and the body when wearing it, It is ingeniously designed in a non-equidistant continuous arrangement, so that the loose part is loose and the tight part is tight, but the tight part of the elastic waist will still cause stretch marks or red marks on the abdomen of infants after long-term use, which will affect the wearing comfort.
