ISOLIERENDE STRUKTUR.

摘要

The inner wall of this container is filled with plates of hard foam (14, 15, 17, 19, 21) and placed under vacuum. The foam acts as a spacer between the two inner (1) and outer (2) casings of the container and prevents their deformation through the action of pressure. Its adhesive bonding to the outer wall (16) makes it possible to render the structure self-supporting. Application to parallelepipedal vessels intended for the deep- freezing of food, by immersion in liquid nitrogen, and to covers for tunnels for deep-freezing food.
