CONTAINER SEALING CAP AND ITS VACUUM SEALING DISK

摘要

FIELD: packing; reusable caps. SUBSTANCE: proposed cap has first film covering container opening. Metal foil, aluminium film in particular, also serve for tight sealing of first film on edge of hole together with removable cap. Removable adhesive insulating layers between first film and metal foil provides separation of metal foil from first film after removal of cap. Cap has flexible layer between removable cap 30 and metal foil. Separating layer between metal foil and flexible layer turns into liquid at evacuation temperatures. Vacuum layer is also found between metal foil and flexible layer. In process of evacuation, vacuum layer absorbs liquid substance separating layer. Adhesive insulating layer has no adjacent vacuum layer. Vacuum sealing disk made of composite material has all above mentioned layers. EFFECT: provision of repeated use of cap. 7 cl, 2 dwg
