  • Patent number: 12241676
    Abstract: This cooling box for storing reagents and the like in a cold state, becomes a cantilever structure where, when a slide rail is disposed outside a cooling space, an installation part is held only by a drawer door. When a heavy article is placed, the installation part is deformed and broken. This cooing box includes a sliding member holder provided with sliding members each including a compression coil spring, which is an elastic body inside a heat insulating box body. When a reagent container is installed in the installation part and drawn out, the installation part and the sliding members slide in contact with each other. When a load exceeding the weight of an installed article is applied to the installation part, the installation part and the sliding member holder come into surface contact with each other. Thus, deformation and breakage of the installation part can be prevented.
