In FIGS. 2A and 2B, the lid part 13 is made of resin, for example, and has a threaded part that threads into the container body 12 on the inside, and a heat insulating member 32 made of polyurethane resin or the like on the inside back surface. The heat insulating member 32 has a thickness (inward direction of the storage section 23) that seals and insulates the opening of the storage section 23.

A cable groove 32A from the lid part 13 to the storage part 23 is formed in the heat insulating member 32, and the cable 51 extending from the temperature sensor 51A located in the storage part 23 is connected to the cable groove 32A and the lid part 13 (lid The cable is led out from a cable hole provided in the body 31).

Further, on the lid body 31 of the lid part 13, cable engaging bodies 43A and 43B are formed at predetermined positions to engage on the wiring of the cable 51 to prevent movement or slippage, and a detachable part 44 is formed at a predetermined position. It is provided to detachably hold the temperature monitoring section 52. The temperature monitoring unit 52 is a so-called logger that displays and records the monitored temperature, and can communicate with a computer, a mobile terminal, etc. as appropriate.

Therefore, as shown in FIG. 3(A), at the position where the cable 51 is led out from the cable hole of the lid part 13, a cable lead-out adjustment part 41 is provided to adjust the position fixation or release of the cable 51. It will be done.

As shown in FIG. 3(B), the cable lead-out adjustment section 41 is composed of an adjustment section 61, a cylindrical elastic body 62, and a cable support section 63, and the adjustment section 61 and the cable support section 63 are made of resin. The cylindrical elastic body 62 is, for example, an elastic member such as resin rubber. The cable support part 63 is provided with a threaded part 63B that threads into the adjustment part 61 at the upper part of the support main body 63A, and a plurality of flexible bodies 63C are integrally formed above the threaded part 63B. . Furthermore, a threaded portion 63D that threads into the lid 31 is provided at the lower part of the support body 63A.

That is, the cable lead-out adjustment section 41 allows the flexible body 63C located inside the adjustment section 61 to pass through the cable 51 and rotate the adjustment section 61 toward the support body 63A from the released state of the cable 51. The cable 51 is fixed in position by being tightened inward by the built-in cylindrical elastic body 62, and thereby the position of the temperature sensor 51A in the storage portion 23 can be adjusted. Note that the structure of the cable lead-out adjustment section 41 shown in FIG. It is selected.

Further, as shown in FIG. 3(A), a cable bending suppressing part 42 is provided near the cable lead-out adjusting part 41 on the lid part 13 (lid body 31). As shown in FIG. 3(C), the cable bending suppressing section 42 is formed by screwing together a suppressing main body 71 and a suppressing main body supporting section 72. That is, the suppression main body 71 is a double-structured cylindrical member having an opening 71A, the top of which is formed in a circular arc shape that contacts the cable 51, and is screwed into the suppression main body support portion 72 on the outer inner surface. A threaded portion (not shown in FIG. 3C) is formed. By making it cylindrical, the cable 51 led out can be brought into contact with any part of the top.

The suppression main body support part 72 is provided with a support main body 72A on the upper surface of the lid part 13 having a fitting hole 72B that matches the support main body 63A of the cable lead-out adjustment part 41, and on the support main body 72A, a suppression main body 72A is provided. A threaded portion 72C that threads into the threaded portion of the main body 71 is formed.

By wiring the cable 51 in a circular shape from the cable lead-out adjustment section 41, the cable 51 can be bent at a non-acute angle when connected to the temperature monitoring section 52 (cable engagement bodies 43A, 43B). This can suppress wire breakage and prevent wire breakage.

In addition, in this embodiment, although the case where the cable bending suppression part 42 was attached on the lid part 13 was shown, it is good also as integrally molded and provided with the said lid part 13.

Therefore, FIG. 4 shows an explanatory diagram of the sensor position adjustment in FIG. 2. As a premise, the temperature monitoring container 11 has an internal space 21 filled with liquid nitrogen, which is a heat storage medium 22, and a cooled object 24, which is a temperature-maintained object, stored in a storage part 23, as shown in FIG. , the storage section 23 is in a thermally insulated state with the lid section 13 closed by the heat insulating member 32.

First, in FIG. 4(A), the adjusting part 61 of the cable lead-out adjusting part 41 is rotated in the loosening direction (counterclockwise), and the temperature sensor 51A is inserted through the cable through hole 61A. The inserted temperature sensor 51A is placed at a desired position in the storage portion 23 from the cable groove 32A of the heat insulating member 32, as shown in FIG. 4(B).

Inside the storage section 23, the temperature is -190°C at the bottom due to liquid nitrogen (thermal storage medium 22), and -150°C as you move upward.The position of the temperature sensor 51A inside the storage section 23 can be adjusted. Accordingly, it is possible to monitor the temperature range in which the cooling time is to be set, for example, depending on the type of the object to be temperature maintained (object to be cooled 24), and the degree of freedom as the temperature monitoring container 11 can be improved. be.

For example, position information is displayed on the cable 51, and when the position of the inserted temperature sensor 51A is determined as shown in FIG. 4(B), the adjustment part 61 is tightened as shown in FIG. 4(C). By rotating the cable 51 in the clockwise direction to fix the position of the cable 51, the temperature sensor 51A is arranged and fixed at a desired position within the storage section 23.

Then, when the temperature sensor 51A is positioned in the storage section 23 and the cable 51 is fixed, the cable 51 in the form led out from the lid section 13 is prevented from bending as shown in FIG. 3(A). By coming into contact with the top of the portion 42, the wiring forms a circular shape from the cable lead-out adjustment portion 41 to the cable engaging body 43A.

In this way, by wiring the cable 51 led out from the cable lead-out adjustment part 41 in a circular shape from the cable lead-out adjustment part 41, the cable 51 can be bent at a non-acute angle by the cable bending suppression part 42. This suppresses bending and reliably prevents wire breakage.

The temperature monitoring container of the present invention can be used in industrial fields such as manufacturing, selling, and using containers for maintaining temperature-maintained objects at a predetermined temperature.
