CONTAINER
Document Type and Number:
Japanese Patent JP2023025332
Kind Code:
A
Abstract:
To provide a container which can achieve both of suppression of heat release of a cold insulator into the container per unit time, and weight saving of the container, and suppress excessive cooling on a lower part of the content.SOLUTION: A container comprises: an inner container 5 and an outer container 2 which are connected in a state of being arranged at inside/outside; a bottomed cylindrical storage space part 6a formed between the inner and outer containers; a cold insulator 6 stored in the storage space part; and an independent foam heat insulation layer 7. The heat insulation layer comprises: a cylindrical heat insulation layer wall 71 covering a lower part of an outer peripheral face of an inner peripheral wall 51 of the inner container; and a heat insulation layer bottom 72 covering a bottom face of an inner bottom wall 52 of the inner container. The outer peripheral face of the inner peripheral wall has: a heat insulation region covered with the heat insulation layer wall; and a heat release region exposed to the cold insulator. The heat release region has a cylindrical main heat release region arranged on an upper side of the heat insulation layer wall, and a content is cooled in the upper main heat release region, and the content is hot insulated in the lower heat insulation region.SELECTED DRAWING: Figure 1
