An insulating container can be configured to retain a volume of at least 1800 cubic centimeters that includes an outer shell and an inner shell. The outer shell and inner shell may be integrally joined together to form an insulated double wall structure with a sealed vacuum cavity between the two shells. A compressible support member may be placed to between a bottom wall of the outer shell and a bottom wall of the inner shell to help form a planar bottom wall of the inner shell when the vacuum cavity is formed.

A thermal insulation canister includes a canister body and a thermal insulation cover. The thermal insulation cover is covered on the canister body. The thermal insulation cover includes an upper cover body, a sealing ring, an adjusting frame and a trigger, the upper cover body is configured to protect an internal structure of the thermal insulation cover. The adjusting frame is rotatably connected to the trigger through the upper cover body. The sealing ring is provided between the upper cover body and the adjusting frame. The adjusting frame is driven by the rotating trigger to compress the sealing ring, which deforms to the side and abuts against the canister body, the sealing ring deforms to the side of the canister body and abuts against the canister body.
