DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper including a removable absorbent.

[0002]

2. Description of the Related Art A disposable diaper is made of a surface material that comes into contact with the skin when worn, an absorbent body that absorbs and retains excrement, a leak-proof sheet that prevents excrement from penetrating into clothing, and an elastic member that imparts elasticity to a hot diaper. It is joined and integrated with a melt adhesive or the like, and worn using fastener means. Because of the integration, there is limited room for the user to select other than the size of several steps (for example, M, L, LL) and the fixing position of the fastener means, and the position of the absorber according to the sex and usage of the wearer. Adjustment has been difficult, and has impaired the comfort of the wearer. The same applies to the complete pants type.

[0003] Furthermore, the position of a flat or pad-type disposable diaper can be adjusted, but it is bulky when used with underwear or other disposable diapers, and it is not easy to fix the disposable diaper together. Therefore, a disposable diaper that can be easily used and is comfortable has been demanded. Also, in recent years, there has been a demand for reduction of materials and waste due to increasing environmental consciousness.
