Abstract

An isothermal transportation container comprises an insulating container and a lid that can seal this insulating container. The insulating container has a plurality of insulating materials arranged overlapped on the inner peripheral face of the insulating container. A thermal conductive member is arranged in a space of the insulating container formed by the insulating materials. The thermal conductive member can accommodate a plurality of laminated packaging containers, each of which accommodates a thermal storage medium and a transported article. The heat in the thermal storage medium in one packaging container can be transmitted to the other packaging container through the thermal conductive member.

Claims

1. An isothermal transportation container comprising an insulating container and a lid that can seal the insulating container, wherein the insulating container has a plurality of insulating materials arranged overlapped on the inner peripheral face thereof, wherein a thermal conductive member is arranged in a space in the insulating container formed by the insulating materials, wherein the thermal conductive member can accommodate a plurality of laminated packaging containers, each of which accommodates a thermal storage medium and a transported article, and is arranged so as to be thermally in contact with the packaging containers, wherein the heat in the thermal storage medium in one packaging container can be transmitted to the other container through the thermal conductive member.

2. An isothermal transportation container according to claim 1, wherein the upper end section of the thermal conductive member is formed into a bent shape, wherein a user can take out the packaging containers by using the bent shape.

4. An isothermal transportation container according to any one of claims 1 to 3, wherein the outer surface of the transported article is covered with a second thermal conductive member.

11. An isothermal transportation container according to any one of claims 1, 3 and 10, wherein the inner shape of the insulating container is cylindrical, and the insulating material is composed of a plurality of mat-like vacuum insulating materials, wherein the vacuum insulating materials are laminated along the cylindrical face and the edge sections of the vacuum insulating materials are varied in the laminate direction.

12. An isothermal transportation container according to claim 11, wherein the end face at the lower side of the vacuum insulating material is lower than the inner bottom face of the insulating container.

13. An isothermal transportation container according to any one of claims 1, 3 and 10, wherein a temperature sensor is provided on the back face of the lid, and a display section for displaying the temperature detected by the temperature sensor is provided on the surface of the lid.

14. An isothermal transportation container according to claim 13, wherein the temperature sensor comes in contact with the thermal conductive member.

15. A carrier container for an isothermal transportation container that is an insulating container which can accommodate a plurality of isothermal transportation containers according to claim 1 or claim 3, and that is provided with temperature display means for displaying the temperature detected by the temperature sensor at each isothermal transportation container.

16. A carrier container for an isothermal transportation container according to claim 15, comprising means for giving an alarm in the case where the temperature in the isothermal transportation container deviates from a predetermined range.

3. An isothermal transportation container comprising an insulating container and a lid that can seal the insulating container, wherein the insulating container has a plurality of insulating materials arranged overlapped on the inner peripheral face thereof, wherein a thermal conductive member is arranged in a space in the insulating container formed by the insulating materials, wherein the thermal conductive member can accommodate a container, that has an insulating material for accommodating a transported article therein, and thermal storage medium as alternately laminated, and is arranged so as to be thermally in contact with the container and the thermal storage medium, wherein the heat in the thermal storage medium can be transmitted to the container through the thermal conductive member.

5. A packaging container used for an isothermal transportation container having an insulating container and a lid that can seal the insulating container and accommodating a thermal storage medium therein, comprising a lid section that can be opened and closed, a box section that forms a sealing container with the lid section, flexible films accommodating the thermal storage medium in the space formed by the lid section and the box section and formed on the mating face between the lid section and the box section for closing the respective spaces, wherein a space in which a transported article can be stored is formed on the center of each film, and a plurality of ribs are formed in the space formed by the lid section and the box section.

6. A packaging container according to claim 5, wherein the outer surface is covered with a thermal conductive member.

7. A packaging container according to claim 5 or claim 6, wherein the ribs are provided so as to project inwardly from the outer wall face of the thermal storage medium accommodating section.

8. A packaging container according to claim 6, wherein the height of each rib formed on the lid section is made higher than the height of each rib formed on the box section.

9. A packaging container according to claim 5, wherein the thermal storage medium is sealed in a container made at least partially of a transparent material.

10. An isothermal transportation container comprising an insulating container and a lid that can seal the insulating container, wherein the insulating container has a plurality of insulating materials arranged overlapped on the inner peripheral face thereof, wherein a thermal conductive member is arranged in a space in the insulating container formed by the insulating materials, and a thermal storage medium is arranged on the side of the inner face of the thermal conductive member, wherein the thermal storage medium can accommodate a subject to be transported that has a plurality of laminated packaging containers, each of which accommodates a transported article therein, and is covered with a second thermal conductive member.
