PROBLEM TO BE SOLVED: To easily ensure the adhesion at a gluing section while improving the disposability by forming a paper container of a material wherein a polyester based film is affixed on the internal surface side of a paperboard, and bonding the paperboard on the material external surface and the polyester based film on the material internal surface, with an emulsion based adhesive on the gluing section of the material. SOLUTION: This container 10 is built up by bending a material 11 of which the major material is paper. In this case, at gluing sections 12 on the body affixing section and the bottom affixing section or the like, the internal surface of the material 11 is superposed on the external surface of a gluing flap 13 of the material 11, and both parts are bonded with an emulsion based adhesive 14. The material 11 is constituted in such a manner that on the internal surface side of a paperboard (coated corrugated fiberboard) 21, a polyethylene based film 22, a paperboard (liner) 23 and a laminate adhesive 24 are provided in order, and a polyester based film 25 is affixed on the innermost layer. Therefore, at the gluing section 12, the paperboard 21 on the external surface of the gluing flap 13 of the material 11, and the polyester based film 25 on the internal surface of the material 11 are bonded with the adhesive 14 applied on the paperboard 21.
