The invention relates to a thermally insulated container used for thermal insulation when storing food and the like. The thermally insulated container manufactured according to the technology of the invention is composed of the following structures: a thermally insulated outer cylinder; an inner cylinder disposed inside the thermally insulated outer cylinder; an inner cylinder cover used for covering the inner cylinder; and an outer cylinder cover used for covering the thermally insulated outer cylinder. In addition, the outer cylinder cover is provided with a locking ring and the thermally insulated outer cylinder is also provided with a hook used for hooking the locking ring so that in the state that the inner cylinder is disposed on the thermally insulated outer cylinder, the locking ring is hooked on the hook, thereby realizing the effect of locking the thermally insulated container. Since the thermally insulated container according to the technology of the invention is provided with the locking ring, the sealing state of the thermally insulated container can be easily maintained. Moreover, the thermally insulated outer cylinder is composed of an outer side cylinder, an inner side cylinder, and thermal insulation materials clamped between the outer side cylinder and the inner side cylinder, so that the thermal insulation performance of the thermally insulated container can be easily improved. |
