Abstract

To simply carry out packing in a constant-temperature transport package, a constant-temperature transport container includes a housing part that is provided on an outer side of a heat insulating container. The housing part is for housing a heat storage material in at least one surface selected from the group consisting of short-side surface parts, long-side surface parts, and a bottom surface part.

First claim

The invention claimed is:

1. A constant-temperature transport container comprising:
a heat insulating container; and
a heat storage material,
the heat insulating container having a luggage formed therein and being in a shape of a cuboid box,
the heat insulating container having side surface parts, a top surface part, and a bottom surface part, and
the constant-temperature transport container comprising a housing part that is provided on an outer side of the heat insulating container for housing the heat storage material in at least one surface selected from the group consisting of the side surface parts and the bottom surface part.

2. The constant-temperature transport container according to claim 1 , wherein the heat insulating container has a fitting recess-and-projection part which is formed on at least one surface selected from the group consisting of the side surface parts, the top surface part, and the bottom surface part so as to enable connection with another heat insulating container.

3. The constant-temperature transport container according to claim 2 , wherein
when the heat insulating container is connected to the another heat insulating container, the housing part is located in a part where the connection is provided between the heat insulating container and the another heat insulating container, and
the another heat insulating container is configured so as to be a heat insulating part for covering the heat storage material housed in the housing part.

4. The constant-temperature transport container according to claim 1 , wherein a plurality of heat storage materials having different melting temperature ranges are housed in the housing part.

5. The constant-temperature transport container according to claim 1 , wherein the housing part has a recess that is fitted to a shape of a luggage-side of one heat storage material or a collective body of a plurality of heat storage materials.

6. The constant-temperature transport container according to claim 5 , comprising a first fitting part that is fitted into the recess so as to be flush with at least an outer surface of the heat insulating container in which the housing part is provided, and that is constituted by at least one member selected from the group consisting of the one heat storage material, the plurality of heat storage materials, and a heat insulating material.

7. The constant-temperature transport container according to claim 1 , further comprising a heat storage material in the luggage inside the heat insulating container.

8. The constant-temperature transport container according to claim 1 , wherein
the housing part is formed in any of the side surface parts, and
the constant-temperature transport container comprises a second fitting part that is fitted into the housing part by a fit, the second fitting part having a cutout part formed therein.

9. The constant-temperature transport container according to claim 8 , wherein the heat insulating container is an assembly type container that includes four side wall panels which serve as the side surface parts, a ceiling panel which serves as the top surface part, and a bottom panel which serves as the bottom surface part.

10. The constant-temperature transport container according to claim 9 , wherein the housing part comprises a plurality of housing parts which are provided in each one of the side wall panels.

11. The constant-temperature transport container according to claim 8 , wherein
the second fitting part is provided with a fitting projection for being fitted into the housing part, and
the housing part is provided with a fitting recess into which the fitting projection is fitted.

12. The constant-temperature transport container according to claim 8 , wherein the second fitting part includes a mounting part in which the heat storage material is mounted.

13. A constant-temperature transport container assembly comprising:
a plurality of the constant-temperature transport containers according to claim 1 ; and
a pallet in which the plurality of the constant-temperature transport containers is loaded, wherein the plurality of the constant-temperature transport containers are fitted and connected to each other.
