PURPOSE:To obtain a container sufficiently durable for use in terms of strength by a method wherein a lid body is molded in connection with a top plate part, a pour-out opening having an edge frame projecting therefrom is formed on the injection molded resin part of a container body, a thin wall part and a finger hold piece for use in opening the container are provided on the bottom surface of a pour-out opening and the lid body is provided on its inner surface with a projecting edge frame engageable with the edge frame of the pour-out opening. CONSTITUTION:At the time of injection molding of a container body A, the synthetic resin part 10b of its top face 10 is molded together with a lid body B. A pour-out opening part 66 is provided with a thin wall part 69 formed on the inner bottom surface 68 of an annularly-shaped edge frame 67 along the edge frame 67 and a finger hold piece 70 in the central part thereof and the lid body B is provided on its inner surface with an edge frame 71 engageable with the edge frame 67 of the pour-out opening part 66. To pour out the contents filled and sealed in the container, the lid body B is opened and the inner bottom surface 68 is separated from the thin wall part 69 by the finger hold piece 70 and, to cover the container, the lid body B is placed back thereon by engaging the edge frame 71 projecting inwardly with the edge frame 67. |
