Title: ULTRA-LOW TEMPERATURE FREEZER
Abstract:
Disclosed is an ultra-low temperature freezer equipped with: a housing which has a first peripheral edge along the periphery of an opening; a door which is mounted on the housing so as to be openable and closable, and which has a second peripheral edge that faces the first peripheral edge in a first direction when the door is closed; and a seal member which is brought into close contact with the first and second peripheral edges when the door is closed. The seal member has: hollow first and second air layer forming portions which are aligned in a row in a second direction between the first and second peripheral edges when the door is closed; and a first connection portion which is connected between the first and second air layer forming portions so as to form an air layer. The first connection portion has a shape that would overlap part of the first and second air layer forming portions if moved in parallel to the second direction. The outer peripheral surface of the first connection portion and the outer peripheral surfaces of the first and second air layer forming portions form first and second recessed portions extending in the first direction.
