Title: Method for manufacturing vacuum double container of metal
Inventor: FUJIYAMA MAMORU
IPC: A47J41/02
Filed: 1987-11-20
Abstract: PURPOSE: To produce a metallic vacuum double-container excellent in heat- insulation and productivity, at a low-cost, by heating and deaerating the space between the inner and outer containers to seal it in the vacuum condition, after an oxidized film has been formed on the external surface of the inner container. CONSTITUTION: Metallic inner and outer containers 1, 3 are connected at the respective mouths to form a double-wall structure, and the external surface of the inner container 1 is covered with a copper or aluminum thin plate 2, and the space between the inner and outer containers is evacuated to produce a metallic vacuum double-container. In this time, after an oxidized film M2 has been formed on the external surface of the inner container 1, the space between the inner and outer containers 1, 3 is heated and deaerated and sealed in the vacuum condition. As a result, the container can be produced at a high productivity and in a low cost. And further, the heat-insulation property can be remarkably improved.
