Abstract

A pants-type sanitary napkin or incontinence guard for women including a front part, a back part and an intermediate crotch part. An elastically stretchable waist border includes first and second side parts and central parts disposed therebetween. The opposing side edges of the front part and the back part are joined together by the first and second side parts of the waist border. The elasticized waist border has a greater resistance to stretch in the first and second side parts than in the central parts thereof, when no load is acting on the sanitary napkin or guard.
