Abstract
A container assembly includes a vessel and a lid removably coupled to the vessel. The lid includes a circumferential rim at an interface with the vessel, wherein the rim is separated from the vessel by a gap, wherein the gap is open to the atmosphere outside the container. The container includes a gasket disposed at a sealing position between the lid and the vessel to seal a reservoir of the vessel from the gap. The rim includes a recess extending circumferentially along a first portion of the rim. The recess forms a portion of the gap and defines a venting zone extending circumferentially along the first portion of the rim. In response to the internal reservoir of the vessel reaching a threshold pressure, a portion of the gasket moves from the sealing position through the gap such that fluid held in the reservoir is vented past the gasket through the venting zone to reduce the pressure of the reservoir.
