Disposable Pants-Type Wearing Article

January 8, 2008

A disposable pants-type wearing article was recently patented. The article includes a front waist region, a rear waist region and a crotch region. An inner sheet defines a surface adapted to come in contact with a wearer’s skin. An outer sheet defines a surface adapted to come in contact with a garment. An intermediate sheet is formed by a plurality of plastic film strips sandwiched between the inner and outer sheets. A plurality of band-like elastic members extends in a stretchable fashion in a waist-surrounding direction in at least one of the front and rear waist regions. A group of leg-surrounding elastic members extends in stretchable fashion in a leg-surrounding direction in the crotch region along peripheral edges of respective leg-openings. The intermediate sheet includes an overlapped region in which the plastic film strips overlap one another in a width of 10 to 100 mm as measured in a longitudinal direction of the wearing article. The overlapped region extends in a transverse direction to a vicinity of the leg-surrounding elastic members. The intermediate sheet includes two overlapped regions; a front one of the overlapped regions is closer to the front waist region than to the rear waist region and consists of a front and a middle plastic film strip. The front and middle plastic film strips overlap and bonded to each other in the front overlapped region by a bonding line that extends continuously in the transverse direction of the article from one end of the front overlapped region to an opposite end of the front overlapped region. A rear overlapped region is closer to the rear waist region than to the front waist region and consists of a rear and middle plastic film strip. The rear and middle plastic film strips overlap and bond to each other in the rear overlapped region.
