Problems solved by technology

However, due to the use of adhesives to fix the elastic material between the two layers of sheets, the elastic folds formed will feel hard and not soft enough. Close fit, it is easy to draw red marks on the user's skin, especially the baby's skin can cause certain damage, and the use comfort is reduced
[0004] In addition, the production method of combining elastic materials with hot melt adhesives to endow materials with elasticity also has problems such as high manufacturing costs and low production efficiency.

Embodiment 1

[0028] Such as Figures 1 to 4 The absorbent article 1 shown has an outer cover layer 2 and an inner cover 3, and is divided into an abdominal region A and a back region C centering on a crotch B in a lateral region.

[0029] The absorbent article 1 has an outer cover 2 and an interior 3 .

[0030] The outer covering layer 2 is composed of a stretchable first sheet 21 and a stretchable second sheet 22, and is coated between the first sheet 21 and the second sheet 22 and extends at least laterally. The elastic adhesive 4 constitutes. The outer covering layer 2 is combined at the side edges of the abdomen area and the side edges of the back area to form the absorbent article 1 .

[0031] The interior 3 includes a liquid-permeable top sheet 31 , a liquid-impermeable back sheet 32 ​​, an absorber 33 interposed between the top sheet 31 and the back sheet 32 ​​, and leak-proof side panels 34 . Preferably, between the absorber 33 and the liquid-impermeable front sheet 31, a flow g...

Embodiment 2

[0036] Such as Figures 5 to 7 The absorbent article 1 shown has an outer cover layer 2 and an inner cover 3, and is divided into an abdominal region A and a back region C centering on a crotch B in a longitudinal region.

[0037] Waist elastic members 6 are provided on front and rear ends of the outer cover layer 2 with respect to the abdomen region A and the back region C, respectively. The waist elastic member 6 does not overlap with the side edges of the abdomen region A and the back region B in the lateral direction. Waist covering sheets 5 extending longitudinally toward the front and rear ends of the outer covering layer 2 are respectively provided at the front and rear ends of the interior 3 , and the waist covering sheets 5 cover the waist elastic member 6 and the front and rear ends of the interior 3 .

[0038] Others are the same as embodiment 1.

[0039] Such as Figure 8 As shown, the manufacturing method of the absorbent article shown in Embodiment 2 of the pr...

Abstract

The invention discloses an absorbent article and a manufacturing method thereof. The absorbent article is provided with an elastic outer coating layer and interior decoration; the elastic outer coating layer comprises a first stretchable sheet and a second stretchable sheet which are overlapped in an up and down mode and an elastic adhesive which is coated between the two sheets and at least extends in the longitudinal direction. The manufacturing method of the absorbent article comprises the steps that the outer coating layer is formed by applying the elastic adhesive between the first sheet and the second sheet and at least in the longitudinal direction, and the interior decoration and the outer coating layer are composited. According to the absorbent article and the manufacturing method thereof, by means of adhesion of the elastic adhesive at high temperature and an elastic stretching property at room temperature, bonding of the first sheet and the second sheet is achieved, no additional elastic material is needed between the first sheet and the second sheet, retraction of the two sheets can be achieved, a rubber band adding device and a steering device are omitted, therefore, the structure is simple, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of sanitary products, in particular to a disposable absorbent product and a manufacturing method thereof. Background technique [0002] A conventional disposable absorbent article is known to have a liquid-permeable front sheet, side sheets for preventing liquid leakage, an absorbent main body for absorbing and retaining liquid, and a back sheet for preventing liquid penetration. In order to enhance the fit of absorbent articles to the body, there has been an improved method of adding elastic waistlines to the front and rear ends of the product interior formed by the sheets on both sides, the absorbent main body, and the back sheet, that is, to form an underpants diaper . In addition, there is another method, which is to add elastic waist elastic members and leg arc elastic members between two layers of covering materials, and add the formed interior to the covering materials to form a panty-style underwear. Diapers...
