ABSORBENT ARTICLE HAVING TWO OR MORE ABSORBING CORES

摘要

An absorbent article has a lower absorbing core and an upper absorbing core. Each absorbing core includes a liquid-holding material and a liquid-permeable core-wrapping sheet. The liquid-holding material is covered by the liquid-permeable core-wrapping sheet, but it also has an exposed portion not covered by the liquid-permeable core-wrapping sheet. The exposed portions of the lower absorbing core and the upper absorbing core face each other and the liquid-holding materials are connected with each other at the exposed portion. Because the liquid-holding material of the upper absorbing core is in direct contact with the liquid-holding material of the lower absorbing core, the area provides a path through which liquid flows smoothly from the upper absorbing core to the lower absorbing core. Also, because the upper and lower liquid-holding materials are covered by the core-wrapping sheets, deformation of the liquid-holding materials is prevented.

1. An absorbent article, comprising:
a lower absorbing core comprising a lower liquid-holding material and a lower liquid-permeable core-wrapping sheet; and an upper absorbing core comprising an upper liquid-holding material and an upper liquid-permeable core-wrapping sheet, wherein the lower liquid-holding material is covered by the liquid-permeable lower core-wrapping sheet at least on a lower side, and on right and left sides, the lower liquid-holding material having a first exposed portion not covered by the liquid-permeable lower core-wrapping sheet on a side facing the upper absorbing core, wherein the upper liquid-holding material is covered by the liquid-permeable upper core-wrapping sheet at least on an upper side, and on right and left sides, the upper liquid-holding material having a second exposed portion not covered by the liquid-permeable upper core-wrapping sheet on a side facing the lower absorbing core; wherein the upper liquid-holding material and the lower liquid-holding material are connected with each other at a connecting area where the first exposed portion and the second exposed portion face each other.
