BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin container, and more specifically, it is possible to heat and cook contents such as foods in a microwave oven, and easily take out sticky contents without residue. The present invention relates to a container made of synthetic resin.

[0002]

2. Description of the Related Art A container made of a synthetic resin for storing ingredients such as egg-bin, parent-child bowl, and bowl, which are cooked in a microwave oven, is resistant to heating by a microwave oven and has a high degree of slipperiness on the inner surface. In addition, it is required that the contents, that is, ingredients and seasonings, can be taken out without remaining. As a conventional container made of synthetic resin, a tray having a conical side surface and a flat bottom surface is proposed in JP-A-63-36739 and JP-A-6-293366.
In Japanese Utility Model Publication No. 6-47829, a tray having a pyramidal side surface and a flat bottom surface is proposed. JP-A-4-36
Japanese Patent No. 7476 proposes a bag-shaped container having a spherical bottom surface.

[0003]

Regarding the above-mentioned conventional container made of synthetic resin, in a tray having a conical side surface and a flat bottom surface, a corner portion is formed at the boundary between the conical side surface and the flat bottom surface, and the container is provided here. There is a high risk that wood and seasonings will remain. In addition, since the side surface is formed into a conical shape, the ingredients that are highly cooked in the tray and arranged orderly to induce appetite collapse when pouring onto the rice through the side surface. There was also the problem of becoming dirty. In the tray having the pyramidal side surface and the flat bottom surface described above, it is relatively easy to pour the ingredients onto the rice while maintaining the state of being arranged in the tray by using the flat portion of the side surface. However, in this tray, in addition to the corners of the boundary between the pyramidal side surface and the flat bottom surface, corners are formed at the boundary portion of the flat surface of the side surface, and ingredients and seasonings remain in these corners. There is a problem that you may do. If the spherical shape of the bag-shaped container described above were adopted for the tray, there would be no corners, but it would be difficult not only to pour the ingredients onto the rice while maintaining the state of being placed on the tray. However, since the tray has a small capacity and the central portion is recessed, it is difficult to arrange the ingredients in the tray in an orderly manner, and there is a problem that the ingredients are increased in the portion where the central portion is depressed and the heating efficiency is lowered.
