    • PROBLEM TO BE SOLVED: To uniformly heat a center part of a container in a similar manner to a peripheral part by forming a bottom wall of the container to be a projected surface so as to be gradually higher from the peripheral part to the center part to facilitate transmission of the microwave in a microwave oven in the container having the bottom wall and the peripheral wall erected from a peripheral edge part. SOLUTION: A container 10 comprises a bottom wall 11, a peripheral wall 12 erected from a peripheral edge, and a flange 13 provided on an outer periphery of an upper edge, and the bottom wall 11 is formed spherical so as to be gradually higher on the whole from a peripheral part toward the center part. The spherical surface may be a true sphere, or an elliptical sphere, and the difference A in height between the center pat and the peripheral part is about 3-10mm. The container 10 is made of a synthetic resin with transmission property of the microwave and the heat, resistance such as polystyrene paper, and a crystalline polyester. The center part is heated more easily than other parts by reducing the thickness of the center part which is difficult for the microwave to transmit than the peripheral part, and the heating temperature is unified.

    • PROBLEM TO BE SOLVED: To attract attention by characters, patterns or the like appearing on a container when the container is at a high temperature to suppress direct touch of a hand to the container to prevent accidents by providing an indication by paint mainly containing juice of citrus which exhibits or changes a color with a high temperature on an appropriate part of a flange or a peripheral wall. SOLUTION: An indication 5 comprising characters, patterns or the like is provided on a flange 4 of a container 1 formed of a metallic foil, heat- resistant synthetic resin or their composite. The indication 5 is drawn with paint which changes or exhibits a color at a high temperature, for example a temperature at the time of cooking. For example, citrus juice such as a lemon or its mixture blended into appropriate binder such as starch paste is preferable as the paint. Alternatively the paint may be used to draw appropriate characters, patterns or the like on a heat-resistant film or a sheet, and this may be adhered to the container 1. The container has the indication 5 appearing when the container 1 is at a high temperature by cooking with heat, thereby attracting attention that touching with hands is dangerous.

    • PURPOSE: To smoothly unseal a cover, by providing notches at both sides of the tab base formed at the peripheral edge of a skirt and making thin the nearby position of the top of the notches and weakening the strength, in a container consisting of a shrink cover in which the skirt hung down from the top wall and the periphery thereof is wound in the flange of container body. CONSTITUTION: A shrink cover 1 is composed of the top wall 2, the skirt 3 hung down from the periphery thereof and a tab 4 is provided at the skirt 3 and notches 5, 5 are provided at both basesides of the tab 4. Nearly triangular cone type or semiconical protrusions 5a, 5a are formed in advance in the skirt 3 on forming the shrink cover 1 when the notches 5, 5 are formed. The shrink cover 1 is put on the base and a cylindrical blade having the same inner shape with the outer shape of the shrink cover 1 is lowered to the base to treat the protrusion 5a so as to cut off. In this time, since the blade hits on the top of notch with considerably strong shocks, the top is brought to a fragile and weak state in such an extent that it gets white a little.

    • PURPOSE:To facilitate ascending/descending motion by pivotally fitting a plurality of turning shafts to a side wall or stairway corner part, and by fixing a turning step to these turning shafts, so that the turning step can be withdrawn or the thickness thereof can be reduced at the time of housing. CONSTITUTION:The turning frame 15 of a turning step 1 (not shown) is fixed by a turning-frame-shaft fixing part 15A with regard to a turning shaft 10, and the turning shaft 10 is pivotally fitted to the bearings 11 that have been fixed to a side wall 3. Further, the turning shaft 10 is adapted to be turned by approximately 90deg. while synchromizing with the respective turning steps 1, and the difference in step between the upper surface of the turning step 1 and the upper surface of a stairway step 2 is made to be approximately 1/2 of the difference in step between stairway steps 2. When the stairway is developed, a turning step 1A is turned by approximately 90deg. in the direction of DOWN, and is drawn out in the direction of OUT, and when it is housed, the turning shaft 10 is turned in the direction of UP. Thus, when a walking handicapped person ascends or descends, the ascending/descending motion can be assisted.
