  • 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.
