Description

Disposable absorbent articles with reusable waist elastic belts including vents

The present invention relates to a disposable absorbent article, and relates to an absorbent article used by connecting a reusable waist elastic belt and a disposable absorbent body together. More specifically, the waist elastic belt has different edges spaced apart in the longitudinal direction and has both ends spaced in the longitudinal direction. It also has grooves spaced in the longitudinal direction at regular intervals from the edge portion inside the longitudinal edge portion, which grooves also have a constant interval inwardly with the longitudinal end portion. In addition, the longitudinal groove which is in contact with the respective longitudinal grooves in the longitudinal grooves are cut. The surface and the grooves in the longitudinal direction are formed on the inner side of the waist elastic belt to form a surface detachable from the waist elastic belt. Accordingly, when the surface formed by the longitudinal grooves is spread outwardly, a portion overlapping with the longitudinal end portion may be formed but longer than the longitudinal edge portion. Therefore, the waist elastic belt can be used to lengthen up to two times the length of the original elastic area by three minutes, it is possible to shape the waist belt with less material, and also the surface formed by the length and longitudinal grooves when worn In the wearer's belly, the part having the vent formed except the formed surface is fixed to the wearer's back so that the wearer secures the absorbent body by fixing the absorber by two sides having a predetermined area separated from each other on the back. The present invention also relates to a disposable absorbent article which is disposed of after use by fixing the disposable absorbent to the waist elastic belt to improve breathability by the formed vent.

Disposable absorbent article in the present invention consists of a reusable waist elastic belt and disposable absorbent body, and is applied to baby and children's disposable absorbent articles, women's sanitary ware and panty liner as absorbent means for absorbing and discarding body waste 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 leakage 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. A receiving or securing element of means for connecting and securing the disposable absorbent body to the reusable waist elastic belt is also attached to the liquid impermeable backsheet.

Known disposable diapers include re-adhesive tape systems or mechanical fastening hooks and loop systems on the side waist and fastening means on the front waist, and the front and rear waist areas. Waist elastics are applied to form a disposable diaper.

The waistband does not function as a waistband because the height of the waistband and the fastening means are not located 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.

In order to solve these problems, the present invention has formed a disposable absorbent article using a waist elastic belt and a disposable absorbent interconnected with a waistband and a fastening means.
