Abstract
Vacuum insulated containers are disclosed in which the usual metallic coating applied to the vacuum filler is omitted. In its place an electrically nonconducting, nonadsorbent granular material, such as finely divided silica, is employed in the annular, evacuated space to reduce infrared radiation loss. The construction is safe for use in microwave ovens and has a relatively high insulating efficiency as compared with vacuum fillers without infra barriers and nonvacuum insulated containers.
