<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional paper-made or resin-made container has a single structure so that it is easy to break and unsuitable as a container for an object with a heavy weight and a large volume, heat inside and outside the container is easy to transmit, and a lid cannot be opened unless the container is largely rotated as the lid has only one knob. <P>SOLUTION: In order to prevent heat inside and outside the paper-made or resin-made container from mutually transmitting and to enable the object with a heavy weight and a large volume to be received, bulkheads 5 are provided along a periphery 1 of a container body, between an inner wall 3 and an outer wall 4 of a bottom 2, and between a surface layer 6 and an inner layer 7 of the top seal structured lid for coupling them. This improves heat insulation as the container and allows the heavy object or the large volume object to be accepted. An area of an upper surface of a bulkhead 5-1 increases a contact area with the lid, thereby preventing contents from leaking or a bacteria from entering from the outside. By providing a plurality of knobs of the lid, the lid can be easily opened by a small rotation of the container, so that the container is difficult to tumble. <P>COPYRIGHT: (C)2003,JPO |
