This spherical insulated container is constructed from a pair of concentric spheres between which is formed a chamber. Communication of liquids to be thermally insulated within the interior sphere is provided by adjacent openings in each sphere defining a mouth area. Either a thermally insulating cap or pump dispenser seals the mouth of the container. A pump dispenser provides a convenient mechanism for dispensing liquids from a spherically shaped insulated container.

Spherical vacuum insulated container

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.

Microwave safe vacuum insulated containers and method of manufacture

A vacuum bottle construction is disclosed in which the vacuum filler is formed from a pair of concentric thin wall metal cylinders. The cylinders are formed of a thin metallic material, such as mild steel, which is unable to withstand the pressure differential of atmospheric pressure on one side and a vacuum on the other side. To prevent collapse of the filler a rigid jacket is provided over the outer wall in intimate contact therewith to prevent collapse.
