AI Technical Summary

Technical Problem

Existing absorbent materials are difficult to keep in a compact state after use, and the adhesive tape is prone to self-adhesion or breakage of the bonding surface due to repeated stretching and contraction, affecting the use effect.

Method used

An absorbent article has been designed in which the waste strip is configured in a three-fold state, the elongated part and the fixed part are stretchable in the length direction, and when contracted, they form a convex curved shape opposite to the main body, reducing the possibility of self-adhesion.

Benefits of technology

It effectively prevents the waste tape from self-adheding during shrinkage, ensuring that absorbent items can maintain their waste form smoothly and avoiding cracking and other adverse conditions at the adhesive surfaces.

Abstract

An absorbent article (1) is provided with a disposal belt (10) for maintaining a disposal form, which is arranged on an outer surface (5A) of an article main body portion (1A). A fixing portion (12) of the disposal belt (10), which is fixed to the outer surface of the article main body portion, an elongation portion (15), and a fixed portion (18) are arranged in a length direction (X1) of the disposal belt and are arranged in a folded state on the outer surface (5A). The elongation portion (15) is capable of being stretched and contracted in the length direction after the folded state is released. An adhesive surface (20) is formed on a main body opposite surface (19b) of the fixed portion (18), which faces the article main body portion in a state in which the folded state is released. The elongation portion is configured to generate a curved portion (22) by contracting after being stretched in the length direction. A cross-sectional shape of the curved portion (22) in a width direction (Y1) orthogonal to the length direction has a curved shape in which a side (u) opposite the main body opposite surface is convex.
