The outer bag 3 is made of a material having waterproofness, weatherability, and abrasion resistance, and contains the inner bag 2, and has an upper opening 3a opened and closed freely via a fastener 5. A reinforcing margin 6 is formed on the opening 2a of the inner bag 2, while an overlapped parts 7 are formed on both sides of an upper part of the inner bag 2, respectively. The reinforcing margin 6 and the overlapped parts 7 facilitate the filling of the composite material into the inner bag 2. The outer bag 3 is provided with a holding belt 9. COPYRIGHT: (C)2004,JPO
