[Problem that the invention attempts to solve]

However, with the above structure, the locking device 6 is troublesome to operate, and the lid 5 cannot be removed from the container body 2, which may be a hindrance during cleaning, etc.
In addition, since the hinge 4 and locking device 6 generally protrude from the outside of the heat insulating container, they not only touch your body and get in the way when you carry it around, they can tear your clothes if you tie it around, and the lock may come off by mistake. There were times when I ended up doing something wrong. Moreover, the container body 2 and the lid 5
Since the flat edge of the lid 5 is brought into close contact with the flat edge of the container body 2, either directly or with a gasket attached to the edge of the lid 5, atmospheric heat does not enter into the cooler box 1. It was difficult to maintain the heat retention function for a long time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a heat-retaining container in which the locking device does not protrude from the lid or the main body, the locking device can be easily operated and the lid can be opened and closed, and the container has an excellent heat-retaining function.

[Means for solving problems]

In order to achieve the above objective, the present invention has a lid that has a heat insulating layer between the double walls made of the inner and outer walls at the mouth edge of the container body, which has a heat insulating layer between the double walls made of the inner and outer walls. In the heat-insulating container that is arranged to cover the opening of the container body, a plurality of stepped portions rising toward the outer wall are formed on the mouth edge of the container body, and the lid has a plurality of stepped portions formed on the edge of the lid. A plurality of steps that engage with a plurality of steps formed on the mouth edge are formed in a step shape, and the innermost step of the plurality of steps is provided with the innermost step of the plurality of steps formed on the mouth edge. A gasket is attached to the inner part of the lid and the outer wall corner of the container body, which corresponds to the upper part of the heat-insulating container. A locking member having a claw portion forms a concave portion that is arranged substantially flush with the outer wall of the lid and the container body when the lid is locked, and the locking member is rotated toward either the lid or the container body. It is characterized in that an engaging stepped portion is formed on the container body or lid to engage the hooking claw portion of the locking member.

[Effect]

Therefore, the locking member is placed within the recess when latched and is substantially flush with the outer wall of the lid and container body. In addition, at the joint between the lid and the container body, the innermost part of the multiple tiers is tightly sealed with a gasket, and the multiple tiers form a labyrinth toward the outside, so the heat retention function can be maintained for a long time. Can be maintained.
