Claim 14:
15. An insulated container, comprising:
a bottom;
a peripheral wall extending up from the bottom such that the bottom and the peripheral wall define an interior space of the container;
a lid pivotally attached to the peripheral wall and pivotable to a closed position engaging the peripheral wall to close the interior space such that a difference of temperature is generally maintained between the interior space of the container and an exterior of the container;
a vent passage extending through the peripheral wall or the lid, the vent passage communicating the interior space with the exterior of the container to prevent formation of a suction seal between the lid and the peripheral wall when the lid is engaging the peripheral wall in the closed position;
a retaining frame attached to the peripheral wall or the lid at a location on the peripheral wall or the lid corresponding to a location of the vent passage; and
an air permeable-water impermeable material layer blocking the vent passage to allow air flow through the vent passage while preventing water from leaking out of the vent passage, the material layer positioned between the retaining frame and the interior space of the container;
wherein the vent passage extending through the peripheral wall or the lid defines a length beginning from an exterior surface of the peripheral wall or the lid and ending at an interior surface of the peripheral wall or the lid; and
wherein the material layer is disposed within the vent passage length.
