PROBLEM TO BE SOLVED: To provide a container which holds hot frying oil directly while preventing temperature of its outer wall from rising, can be folded when holding no fry oil to eliminate a need of a large stock space, is easy to dispose of and inexpensive, and can be used to deliver frying oil as a product and to recover waste frying oil. SOLUTION: A three-layer coextrusion tubular blown film consisting of a nylon 6, a polyethylene, and the nylon 6 is pinched and cut into a doubled laminated film having a prescribed length. One end of the doubled film is sealed by heat and made into a bottom to form a flat inner bag 21 with a top open end. The inner bag 21 is bonded with an adhesive 30 partially to the interior of a cardboard box 31 and is folded flatly. When animal frying oil is stored in the cardboard box 31, the inner bag 21 is given a solid shape along the cardboard box 31, and the frying oil is put in the inner bag 21. After the frying oil held in the inner bag 21 is cooled down and solidified, the top of the inner bag 21 is folded and the top board of the cardboard box 31 is closed. COPYRIGHT: (C)2005,JPO&NCIPI
