Abstract

[Object] To provide a thermal insulation container with which the heat/cold insulation effect is kept for longer time without increasing the size and weight of the thermal insulation container. [Solving Means] The thermal insulation container includes an inner container, an outer container, and an overlap region. The inner container includes a first bottom portion, a first side wall portion that extends in a first direction from the first bottom portion and forms a first open end portion, and a first vacuum layer continuously formed inside the first bottom portion and the first side wall portion. The outer container includes a second bottom portion, a second side wall portion that extends in a second direction opposite to the first direction from the second bottom portion and forms a second open end portion, and a second vacuum layer continuously formed inside the second bottom portion and the second side wall portion. The outer container is fitted onto the inner container in such a manner that an inner surface of the second side wall portion and an outer surface of the first side wall portion face each other and forms a storage portion. The overlap region is formed in such a manner that the inner surface of the second side wall portion and the outer surface of the first side wall portion overlap each other.

Dependent claims

A thermal insulation container, comprising:

an inner container including
a first bottom portion,
a first side wall portion that extends in a first direction from the first bottom portion and forms a first open end portion, and
a first vacuum layer continuously formed inside the first bottom portion and the first side wall portion;
an outer container including
a second bottom portion whose inner surface is adjacent to the first open end portion,
a second side wall portion that extends in a second direction opposite to the first direction from the second bottom portion and forms a second open end portion adjacent to an inner surface of the first bottom portion, and
a second vacuum layer continuously formed inside the second bottom portion and the second side wall portion, the outer container being fitted onto the inner container in such a manner that an inner surface of the second side wall portion and an outer surface of the first side wall portion face each other and forming a storage portion;
an overlap region where the inner surface of the second side wall portion and the outer surface of the first side wall portion overlap each other, the overlap region having a length W in the first and second directions, the length W being larger than a length D of the thermal insulation container in a radial direction orthogonal to the first and second directions;
and
a sealing member disposed between the outer surface of the first side wall portion and the inner surface of the second side wall portion, the sealing member being disposed in at least a majority of the overlap region, and the sealing member being configured to suppress heat transfer caused by convection between the outer surface of the first side wall portion and the inner surface of the second side wall portion.

a first side wall portion that extends in a first direction from the first bottom portion and forms a first open end portion, and
a first vacuum layer continuously formed inside the first bottom portion and the first side wall portion;
an outer container including
a second bottom portion whose inner surface is adjacent to the first open end portion,
a second side wall portion that extends in a second direction opposite to the first direction from the second bottom portion and forms a second open end portion adjacent to an inner surface of the first bottom portion, and
a second vacuum layer continuously formed inside the second bottom portion and the second side wall portion, the outer container being fitted onto the inner container in such a manner that an inner surface of the second side wall portion and an outer surface of the first side wall portion face each other and forming a storage portion;
an overlap region where the inner surface of the second side wall portion and the outer surface of the first side wall portion overlap each other, the overlap region having a length W in the first and second directions, the length W being larger than a length D of the thermal insulation container in a radial direction orthogonal to the first and second directions;
a sealing member disposed between the outer surface of the first side wall portion and the inner surface of the second side wall portion, the sealing member being disposed in at least a majority of the overlap region, and the sealing member being configured to suppress heat transfer caused by convection between the outer surface of the first side wall portion and the inner surface of the second side wall portion;
a heat/cold insulation portion disposed inside the storage portion, an object to be heat-insulated or cold-insulated being disposed in the heat/cold insulation portion;
and
a thermal storage member disposed around the heat/cold insulation portion.

A heat/cold insulation apparatus, comprising:

an inner container including
a first bottom portion,
a first side wall portion that extends in a first direction from the first bottom portion and forms a first open end portion, and
a first vacuum layer continuously formed inside the first bottom portion and the first side wall portion;
an outer container including
a second bottom portion whose inner surface is adjacent to the first open end portion,
a second side wall portion that extends in a second direction opposite to the first direction from the second bottom portion and forms a second open end portion adjacent to an inner surface of the first bottom portion, and
a second vacuum layer continuously formed inside the second bottom portion and the second side wall portion, the outer container being fitted onto the inner container in such a manner that an inner surface of the second side wall portion and an outer surface of the first side wall portion face each other and forming a storage portion;
an overlap region where the inner surface of the second side wall portion and the outer surface of the first side wall portion overlap each other;
a heat/cold insulation portion disposed inside the storage portion, an object to be heat-insulated or cold-insulated being disposed in the heat/cold insulation portion;
and
a thermal storage member disposed inside the storage portion, the thermal storage member being disposed such that the heat/cold insulation portion is disposed at a position closer to the first bottom portion than it is to the first open end portion, so as to be closer to the first bottom portion than it is to a connection port of the thermal conduction path that provides thermal connection between the storage portion and external space.
