Abstract

An absorbent article with a liquid barrier layer which lies nearest the user's body and which includes a first and a second pair of elastic members. The surface layer is used as the article's supporting unit in which other included parts, such as reverse layer and absorption body, are suspended. The surface layer also has an elongate opening which permits liquid communication from the user's genitals to the inside of the article.

Claims8

Dependent claims

An absorbent article extending in a longitudinal direction, and comprising:

an inner surface, which in use, is intended to be directed towards a user;
an outer surface, which in use, is intended to be directed away from the user;
an elongate absorption body comprising at least one layer of absorbent material;
a liquid-impermeable backing layer at the outer surface;
a liquid-permeable surface layer at the inner surface;
said absorption body being enclosed between the backing layer and the liquid-permeable surface layer;
a first pair of elastic members extending in a direction which coincides with the longitudinal direction;
a second pair of elastic members extending in a direction which coincides with the longitudinal direction;
a liquid barrier layer arranged on the inner surface of the absorbent article with the liquid-permeable surface layer placed between the liquid impermeable backing layer and the liquid barrier layer;
the first pair of elastic members and the second pair of elastic members being secured solely and directly to the liquid barrier layer;
said liquid barrier layer being connected in a liquid-tight manner with a seam between the liquid barrier layer and the backing layer within an edge portion which includes said liquid barrier layer and said backing layer;
said edge portion running around the article;
said liquid barrier layer having an elongate opening which permits unimpeded passage of bodily excretions from genitals of the user to the liquid-permeable surface layer;
said backing layer being essentially nonelastic, whereby during use, the liquid barrier layer alone constitutes supporting portions of the article and all portions bearing against the user;
said liquid barrier layer having parts which are designed to directly or indirectly carry means for securing the article on the user;
and
one elastic member of said first pair of elastic members being separated from an adjacent elastic member of said second pair of elastic members by a distance which is smallest in an area of the article, which in use, is intended to be arranged at a groin of the user, and diverges forwards and backwards from said area in the longitudinal direction.
