PROBLEM TO BE SOLVED: To provide a rack for gas-phase type liquid nitrogen storage devices which is capable of repeatedly performing, on a stable and reliable basis over an extended period of time, a consignment storage operation of rapidly, stably, reliably storing cryobox transportation and storage containers and keeping them at extremely low temperature.SOLUTION: A storage port for a cryobox transportation and storage container is arranged on the front of a rack, a lid member is arranged on the right side surface portion of the storage port, a lid member is arranged on the right side surface portion of the storage port, and an upright gripping part is arranged on the upper part of the rack flat surface. In addition, among the rack wall surfaces. the wall surface where the rack front surface and the rack left side surface are in contact with each other, the corner portion of the wall surface where the rack front surface, the rack flat surface, and the rack left side surface are in contact with each other, the corner portion of the wall surface where the rack front surface, the rack bottom surface, and the rack left side surface are in contact with each other, and the corner portion of the wall surface where the rack front surface, the storage part bottom surface, and the rack left side surface are in contact with each other, are each lacked such that the cryobox transportation and storage containers stored in the storage part do not protrude.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】クライオボックス運搬および保管用容器を迅速安定確実に収納し、極低温下に保持する委託保管作業の運用を、長期的に繰り返しかつ安定確実な実施が可能な、気相式液体窒素保存機器用ラックの提供。【解決手段】ラック正面にクライオボックス運搬および保管用容器の格納口が配され、該格納口の右側面部には蓋部材が配され、格納口の右側面部には蓋部材が配され、ラックの平面の上部には立設された把持部が配され、さらに、ラック壁面のうち、ラック正面とラック左側面とが接する位置にある壁面とラック正面とラック平面とラック左側面とが接する位置にある壁面の角部分とラック正面とラック底面とラック左側面とが接する位置にある壁面の角部分とラック正面と格納部の底面とラック左側面とが接する位置にある壁面の角部分とが、それぞれ格納部に格納されたクライオボックス運搬および保管用容器が突出しないように欠いた状態とする。【選択図】図2
