PROBLEM TO BE SOLVED: To provide posttreatment means which can fix an article in a discarded state while the article can be retained in a developed state by easy operation.SOLUTION: Pouched band insertion portions 81, 82 which have outlets 83, 84 to the outer surface of the article are disposed on an abdomen side portion F and on a back side part B in the center of the width direction of the article respectively. While extending from the front end part of the abdomen side portion F through the outlet 83 of the band insertion portion 81 of the abdomen side portion F and the outlet 84 of the band insertion portion 82 of the back side part B in this order to the rear end part of the back side part B, two or more elastic and stretchable bands 90 which have fixed portions for the article respectively are prepared on the front end part of the abdomen side portion F and on the rear end part of the back side part B. These two or more bands which intersect at a less than 90 degree angle mutually between respective outlets 83 and 84 are prepared in a radial fashion. A part between fixed portions 87 and 88 in the band 90 is organized so that it can be drawn from the outlets 83, 84 of the band insertion portions 81, 82 to the outside of the article with the stretch.
