The present invention relates to a disposable absorbent article, and relates to an absorbent article for use together by connecting a reusable elastic waist belt and a disposable absorbent body. More specifically, the waist belt is elastic and consists of two parts having a closed curved waistband and a flap partially formed on the waistband. The waistband includes elastic means, and the waistband rear portion relates to a disposable absorbent article that is disposed of after use by fixing the disposable absorbent to the waistbelt flap including a flap and connecting means for easy connection with the disposable absorbent.

Disposable absorbent article in the present invention is composed of a reusable waist belt and disposable absorbent body, and is adapted to disposable absorbent articles for baby and adult, women's sanitary ware and pantyliner as absorbent means for absorbing and discarding body excrement for a certain period of time.

In the present invention, the disposable absorbent body is formed by inserting an absorbent core between the liquid permeable top sheet and the liquid impermeable back sheet to mutually bond. The absorbent core is mainly made of fluffy pulp made by grinding pulp. In order to improve the performance of the absorbent core, a super absorbent material may be mixed with the fluffy pulp.

The disposable absorbent body may also form a leakage preventing pocket by disposing a leak band and leg elastics, which are leakage preventing means, outside the absorbent core in the longitudinal direction of the disposable absorbent body to prevent leakage of the absorbent core.

In addition, a means for connecting and securing the disposable absorbent body to the reusable elastic belt may also have the receiving or fixing element attached to the liquid impermeable backsheet.

Known disposable diapers are attached to the disposable absorbent body on both sides of the front or rear waist by a fastening means and attach a hook which is a re-adhesive tape system or a mechanical fastening means by a fastening system, and the front or rear waist as an area for accommodating the fastening system. A receiving area of constant size is formed in the. In addition, by applying a waist elastic body to the front waist region, to form a disposable diaper.

The waistband does not function as a waistband because the waistband and the fastening means are not positioned on the same line when the known disposable diaper is worn for a long time. Therefore, the waistband is folded inside or rolled out to impair the feeling of wearing, and during long-term wear, disposable diapers flow down to provide a cause of urination when urinating.

Another problem of the disposable diaper is that the edges adhered to the upper surface and the back sheet of the fastening means of the re-adhesive tape irritate the skin of the thighs, and in some cases, may cause skin scars.

Korean Patent Laid-Open Publication Nos. KP 91-2414 and KP 92-702983 provide an absorbent article having a fixing means at both ends of the waist belt with a belt-shaped waist belt and interconnecting disposable absorbents.

However, the present invention provides a closed curved reusable elastic waist belt having the function of the waistband and the fastening means of the known disposable diaper to solve the problems of the known disposable diaper, to the reusable closed curved elastic waist belt The present invention provides a disposable absorbent article for retaining a waist belt flap including an absorber connecting means at a rear side of a waistband so that the disposable absorbents can be interconnected and used for fixing and disposing of the disposable absorbents.

The configuration of the present invention in more detail as follows.
