Ventilated lid for insulated container

An insulated container assembly, comprising:

• a container body, including an inner wall and an outer wall coupled at a top of the container body and separated by a vacuum gap;
• and
• a lid that is reversibly attachable to the container body, the lid including:
• a flexible gasket configured to facilitate a seal between the lid and an inner wall of the insulated container, and further configured to expand into an interior compartment of the insulated container responsive to a vacuum developing in the interior compartment;
• a diaphragm chamber situated opposite the flexible gasket from the interior compartment when the lid is fully engaged with the insulated container, the diaphragm chamber located on an interior of a mating sleeve configured to couple the lid to the insulated container;
• and
• one or more air channels coupling the diaphragm chamber to an exterior of the lid.

An insulated container assembly, comprising:

• a container body, including an inner wall and an outer wall coupled at a top of the container body and separated by a vacuum gap, the inner wall including a plurality of mating protrusions;
• and
• a lid that is reversibly attachable to the container body, the lid including:
• a flexible gasket configured to facilitate a seal between the lid and an inner wall of the insulated container;
• and
• a mating sleeve coupled to the flexible gasket via a coupling ring, such that the flexible gasket is fixed in position relative to coupling ring, such that the coupling ring rotates freely around the mating sleeve, and such that the flexible gasket does not rotate relative to the inner wall when the lid is being removed from the container body.
