Abstract

Disclosed herein is a temperature controlled case. The temperature controlled case includes a base and a stepped portion protruding from an upper surface of the base, wherein the stepped portion has a rectangular shape having a major axis and a minor axis in top plan view, a height of the base is the same as a maximum height of the stepped portion protruding from the base, and maximum distances from an edge of the base to the stepped portion in the major axis and minor axis directions are the same as the height of the base or the maximum height of the stepped portion.

First claim

The invention claimed is:

1. A temperature controlled case, comprising:
a base having:
an outermost edge;
a first surface;
a second surface opposite to the first surface;
a first portion having a first height extending from the second surface to the first surface;
a stepped portion having a second height protruding from the first surface of the base and the stepped portion being spaced apart from the outermost edge of the base by a selected distance, the stepped portion having a major axis and a minor axis transverse to the major axis, the first height being the same as the second height of the stepped portion protruding from the first portion, and the selected distances from the outermost edge of the base to the stepped portion in a major axis direction and minor axis direction being the same as the first height of the first portion, the stepped portion also having a third surface opposite to the second surface, a first recessed portion disposed at a first edge of the stepped portion and a second recessed portion at a second edge of the stepped portion opposite to the first recessed portion, the recessed portions separated by the third surface, the recessed portions being disposed parallel to the minor axis direction, each of the recessed portions having a fourth surface opposite to the second surface;
first sidewalls extending from the second surface to the first surface, the first sidewalls having the first height;
second sidewalls extending from the fourth surfaces of the recessed portions, respectively, to the third surface, the second sidewalls being spaced apart from the first sidewalls by the first surface and the fourth surfaces of the recessed portions, respectively, the second sidewalls having a third height; and
third sidewalls extending from the first surface to the fourth surfaces of the recessed portions, respectively, the third sidewalls being between the first sidewalls and the second sidewalls, the third sidewalls having a fourth height that is a difference between the second height and the third height.

2. The temperature controlled case according to claim 1 , wherein a difference between a first length of the stepped portion in the major axis direction and a second length of the stepped portion in the minor axis direction is two times the first height of the base.

3. The temperature controlled case according to claim 2 , wherein a length of the base in the minor axis direction is the same as the first length of the stepped portion in the major axis direction.

4. The temperature controlled case according to claim 1 , wherein widths of the fourth surfaces of the recessed portions extending from the third sidewalls to the second sidewalls is the same as the second height of the stepped portion.

5. The temperature controlled case according to claim 1 , wherein the third height of the recessed portions is half or less the second height of the stepped portion.

6. The temperature controlled case according to claim 1 , wherein the stepped portion has an orientation mark formed on the surface to indicate the minor axis direction or the major axis direction.

7. The temperature controlled case according to claim 1 , wherein the temperature controlled case further includes an injection port coupled to the base.

8. The temperature controlled case according to claim 1 , wherein the stepped portion further includes a depressed portion in a surface of the stepped portion.

9. The temperature controlled case of claim 1 , wherein the recessed portions are configured to buffer volume expansion of a temperature regulating material in the base.

10. The temperature controlled case of claim 1 , further comprising fourth sidewalls transverse to the first sidewalls, the second sidewalls, and the third sidewalls, the fourth sidewalls having the second height of the stepped portion.

11. A temperature controlled package capable of storing a temperature sensitive object, comprising:
an external box having an interior space and capable of being open or closed at a side; and
a plurality of temperature controlled cases disposed corresponding to each facet of the external box, each of the temperature controlled cases being coupled to the interior surface of the external box, each one of the temperature controlled cases being coupled to another one of the temperature controlled cases, each one of the plurality of temperature controlled cases including:
a first surface;
a second surface opposite to the first surface;
a first sidewall extending from the first surface to the second surface, the first sidewall having a first height;
a third surface opposite to the first surface;
a second sidewall extending from the second surface to the third surface, the second sidewall having a second height that is less than the first height;
a fourth surface opposite to the first surface;
a third sidewall extending from the third surface to the fourth surface, the third sidewall having a third height that is less than the first height; and
a fourth sidewall extending from the second surface to the fourth surface, the fourth sidewall being transverse to the first sidewall, the second sidewall and the third sidewall, the fourth sidewall having a fourth height equal to a summation of the second height and the third height.

12. The temperature controlled package according to claim 11 , further comprising:
an insulator interposed between the temperature controlled cases and the external box.

13. The temperature controlled package of claim 11 , wherein the external box has a hexahedral shape.

14. The temperature controlled package according to claim 13 , wherein the stepped portions of at least two temperature controlled cases of the plurality of temperature controlled cases are disposed at opposite sides in the major axis direction of a first temperature controlled case of the plurality of temperature controlled cases that is disposed on a bottom surface of the external box, the at least two temperature controlled cases are placed on the stepped portion of the first temperature controlled case, and the stepped portions of another two temperature controlled cases of the plurality of temperature controlled cases are disposed at opposite sides in the minor axis direction of the first temperature controlled case, the at least another two temperature controlled cases are placed on a base portion of the first temperature controlled case, the first temperature controlled case is distinct from the at least two temperature controlled cases and the at least another two temperature controlled cases.

15. The temperature controlled package of claim 11 , wherein the temperature controlled cases further include an injection port.

16. The temperature controlled package of claim 11 , wherein the temperature controlled cases are filled with a temperature regulating material.

17. The temperature controlled package of claim 16 , wherein the third surface and the third sidewall are configured to serve to buffer volume expansion of the temperature regulating material and serve to guide assembly of the plurality of temperature controlled cases.
