Abstract
Container assemblies (100) that transition between a sealing state and a retained venting state are described. The container assemblies each include a body portion (110) having an open end (113), and a lid portion (120) adapted to cover the open end of the body portion to create an enclosed volume, e.g. reservoir, and additionally comprise a venting feature (140). When the fluid pressure within the enclosed volume is less than a threshold pressure, the lid portion is in a sealing state such that the lid portion and the body portion cooperate to maintain a substantially fluid-tight seal against fluid leaving the enclosed volume. When the fluid pressure is greater than or equal to the threshold pressure, the lid portion is in a retained venting state such that the excess fluid pressure from the enclosed volume vents through the venting feature while retaining the lid portion on the body portion.
