Heat insulating container

A heat-insulating container comprising:

• a straight cylindrical container having a heat-insulating vacuum layer disposed between a metal inner cylinder with a closed bottom end and a metal outer cylinder with a closed bottom end, said inner and outer cylinders being joined and sealed to each other and forming an open end of said straight sealed container;
• a synthetic resin inner case with a bottom at one end and a wide mouth at the other end and for insertion into said straight cylindrical container;
• and
• a cap for closing said open end of said straight cylindrical container, said cap having a heat-insulating plug member fitted into said mouth of said inner case and a ring for rotatably supporting said plug member, said bottom of said inner case having an engagement portion for abutting a lower peripheral edge of a large-diameter storage container positioned in said cylindrical container and a recess for receiving an end of a small-diameter storage container positioned in said cylindrical container and means on said ring member for engaging said plug member and for moving said plug member in a first axial direction axially of said heat-insulating container and away from said mouth of said inner case when said plug member is rotated in a first circumferential direction and for moving said plug member in a second axial direction axially of said heat-insulating container and toward said mouth of said inner case and into engagement with said mouth when said plug member is rotated in an opposite circumferential direction;
• said cap including a cap mounting member mounted on an upper end of said straight cylindrical container with a support shaft in a tangential direction of said cap mounting member, and a link portion on said ring for engagement with said support shaft, said link portion having a groove in which said cap is movable in an axial direction of said ring.
