<p>PROBLEM TO BE SOLVED: To eliminate the need for a welding or other joining work for a bottom plate and a frame. SOLUTION: In an integrally molded container 10 comprising plastic sheets or plastic thin plates, a protruding strip 2 is formed on the outer circumferential surface of the container 10 and the central portion of the strip is made higher than the ends thereof. Thus the strength of the container itself can be maintained so that a container for food which can contain processed food can be obtained. And by setting the container 10 in a foam plastic frame 5 having a groove 8 on its inner circumferential surface so that the strip 2 is fitted in the groove 8, a simple container can be provided in place of a conventional container wherein a frame is welded to an inner container.</p> |
