US Patent 11930944 Container and method of forming a container

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 an internal passageway extending between the internal reservoir and a spout opening, which may be smaller than the opening of the canister. The spout opening may be sealed with an upper cap that has a magnetic top surface. The upper cap may be selectively coupled to seal the spout opening, or may be magnetically coupled to a magnetic docking surface of a docking structure on the spout adapter.
