An insulating container can be configured to retain a volume of liquid, and include a canister having a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a spout adapter, the spout adapter having a spout channel extending between the internal reservoir and a spout opening, smaller than the opening of the canister. The spout opening may be sealed with a cap having a magnetic top surface, and the spout adapter may be further removably coupled to a lid that may be used as a cup into which a volume of the liquid can be poured.

Disclosed is a cover body structure and a bottle thereof. The cover body structure includes: a rotary cover, a dust-proof cap, a driving assembly, and a toggle member. The rotary cover is provided with a straw and the dust-proof cap is rotatably connected to the rotary cover, to enable the dust-proof cap and the rotary cover to have a buckled state and a flip state. By connecting one end of the driving assembly to the dust-proof cap, rotatably disposing the toggle member on the rotary cover, and rotatably connecting the other end of the driving assembly to the toggle member, the toggle member can be driven to enable the toggle member to rotate to a liquid path blocked state in which the straw is bent in the buckled state and rotate to a liquid path conducted state in which the straw is rebounded and restored in the flip state.
