A vacuum heat insulating layer (14) is formed between a thin plate-shaped outer wall (12) and an inner wall (13). Although not shown in detail, the container body 11 may have an opening / closing structure having a heat insulating lid or a completely closed structure having no lid. The container body 11 has an opening 15 penetrating its wall.
Are formed. The inner peripheral surface 16 of this opening is formed in a tapered shape that widens toward the outside of the container body 11.

密接する外周テーパ面18が形成されている。A plug 17 having a vacuum heat insulating structure is mounted in the opening 15 like the container body 11, and the opening 15 can be opened and closed. The plug body 17 is formed with an outer peripheral tapered surface 18 that comes into close contact with the tapered inner peripheral surface 16 of the opening 15 when the plug body 17 is closed.

連結部材19の他端側に支持されている。One end of a rod-shaped connecting member 19 extending toward the inside of the container body 11 is attached to the plug body 17.
At the other end of the connecting member 19, a pair of flanges 20 and 21 are provided at a distance in the axial direction. Reference numeral 22 denotes a bimetal, which is formed in a disc shape, and the other end side of the connecting member 19 penetrates through the central portion thereof. The peripheral edge of the penetrating portion is sandwiched between the flanges 20 and 21, and is supported on the other end side of the connecting member 19.

ものなどが用いられる。The bimetal 22 is formed in a convex shape protruding toward the inside of the container body 11, and the low expansion metal 23 is arranged on the outside of the convex shape, that is, on the inside side of the container body 11.
The high expansion metal 24 is arranged on the inner side of the convex shape, that is, on the side closer to the inner wall 13. Specifically, for example, a low-expansion metal 23 made of an iron-nickel alloy containing about 42% nickel and an high-expansion metal 24 made of an iron-nickel-chromium alloy are used as an electric bimetal plate equivalent to four kinds. Those having a convex shape are used.

に構成されている。すなわち、溝27の内径がバイメタル
22の外径よりも大きくなるように構成されている。A fixing member 25 is arranged inside the container body 11 such that it is fixed to the inner surface of the inner wall 13. The fixing member 25 has an inward annular groove 27 capable of accommodating the circumferential edge 26 of the bimetal 22, and the groove bottom portion 28 of the groove 27 has a radial gap between the circumferential edge 26 of the bimetal 22 and the circumferential edge 26. It is configured to hold 29. That is, the inner diameter of the groove 27 is bimetal.
It is configured to be larger than the outer diameter of 22.

外周テーパ面18が開口部15の内周面16に圧接し、それに
よって開口部15は栓体17によって確実に封止される。In such a structure, when the temperature in the container body 11 is low, there is a gap 29 between the circumferential edge 26 of the disc-shaped bimetal 22 and the groove bottom 28 as shown in the figure. Then, for example, when the circumferential edge 26 is engaged with the side surface of the groove 27, the convex elasticity of the bimetal 22 acts so that the outer peripheral tapered surface 18 of the plug 17 is pressed against the inner peripheral surface 16 of the opening 15. As a result, the opening 15 is reliably sealed by the plug 17.

部材19などの他の部材には何ら力を作用しない。When the temperature inside the container body 11 rises due to self-heating of the contents inside the container body 11, the bimetal 22 has its central portion supported by the other end of the connecting member 19 accordingly. Then, it thermally expands so as to expand its diameter.
And until the temperature reaches a predetermined temperature, the tip of the circumferential edge 26 approaches the groove bottom portion 28 due to this thermal expansion, and the gap 29 is gradually closed, but only free thermal deformation is performed, and the connecting member 19 and the like. No force is applied to the other members of the.

形状が反転するように熱変形し始める。At a predetermined temperature, as shown in FIG. 3, thermal expansion causes the tip of the circumferential edge 26 to contact the groove bottom 28, and free thermal deformation in the radial direction is no longer possible. Then bimetal
22 is now deformed in the thickness direction, and the low expansion metal 23 is arranged on the outer side of the convex shape and the high expansion metal 24 is arranged on the inner side thereof. Therefore, as shown in FIG. Begins to be deformed by heat.

戻される。Therefore, the plug 17 is pushed open through the connecting member 19 by this operation stroke at the time of reversing, and a gap is formed between the tapered outer peripheral surface 18 of the plug 17 and the inner peripheral surface 16 of the opening 15. 30 is generated, and low-temperature outside air 31 enters the container body 11 through the gap 30. As a result, the temperature inside the container body 11 is lowered, and the bimetal 22 is also cooled and returned to its original shape, whereby the plug body 17 is returned to the original closed position via the connecting member 19.

In addition, in the thing which has the above-mentioned heat insulation cover, the opening / closing structure shown in this figure can be provided in this heat insulation cover. In addition, the illustrated opening / closing structure can be provided at a plurality of locations in the container body 11, and by doing so, variations in temperature inside the container body 11 can be reduced.

あるため信頼性が高いという、すぐれた効果を有する。As described above, according to the present invention, the heat-deformable member is interlockingly connected to the plug body capable of sealing the opening formed through the wall portion of the container body having the hermetically sealed structure, Since the plug is opened and closed by the thermal deformation of the thermal deformation member according to the internal temperature of the container, the temperature inside the container body can be kept within a certain range without the need for equipment such as a blower. It has an excellent effect that the whole structure can be made compact, it does not require external energy such as electric power, and is highly reliable because it is self-contained.
