Problems solved by technology

However, the use of the above-mentioned conventional absorbent articles cannot completely prevent leakage, especially the use state of the absorbent article in actual use does not always remain in the above-mentioned use state, for example, the excretion part of the user often deviates from the absorbent article during use. central part of the absorber
In addition, the absorbent article cannot adapt to the complex shape caused by the user's movement during use, and there is also a gap between the absorbent article and the user's use part.
Under these circumstances, the leakage preventing effect satisfactory to the user cannot be obtained using the above-mentioned conventional absorbent articles.
[0005] In addition, the front and rear ends of each folded flap of the above-mentioned conventional absorbent article are bonded to the front and rear portions of the absorbent article, so that the adaptability of the portion in contact with the user's excretion site during use is also insufficient, Leakage still occurs on both sides of the absorbent article

Abstract

An absorbent article having a central absorbent body comprising a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent member interposed between the topsheet and the backsheet, and a pair of flaps provided in the opposing longitudinal sides of the central absorbent body, is characterized in that: each of the flaps is connected with the surface of the absorbent article which, in use, does not contact the skin of the wearer, each of the flaps forms an antileakage wall along each edge of the opposing longitudinal sides of the central absorbent body, each of the flaps is folded outwardly from the central absorbent body to form an antileakage surface, and the antileakage surface in the portion which contacts the discharging portion of the wearer in use is a surface substantially parallel to the skin-contacting surface of the absorbent article.

Description

technical field [0001] The present invention relates to an absorbent article, such as a sanitary napkin, which is brought into contact with the skin of a user to absorb body fluids. The present invention particularly relates to an absorbent article having good leak-proof properties on both sides thereof. Background technique [0002] Various absorbent articles such as disposable diapers and sanitary napkins have been proposed and put into practical use so far. However, conventional absorbent articles have the disadvantage of making the user feel uncomfortable due to leakage on both sides of the absorbent article which often stains the user's clothing. Various attempts have therefore been made to overcome these disadvantages. [0003] For example, it is proposed to form leak-proof partitions on two opposite longitudinal sides of the absorbent article. In addition, it is also proposed to make the absorbent article itself into a shape corresponding to the part where the user ...
