Double-wall insulated container |
摘要 |
A double-wall insulated container has an internal wall and an external wall enclosing an intermediate space which is under partial vacuum. A foam glass granulate fills the intermediate space and supports the walls. The walls may be metal or plastic and sealed with a vapor barrier as necessary to make the space leak-proof. The container may be styled as a Dewar flask for food or beverages, or larger to make it suitable for a household appliance such as a refrigerator.
