Abstract

A lidded vessel assembly comprises a tubular vessel, a lid, and a latching device. The tubular vessel defines a vessel opening and comprises a vessel base, an inner wall, a sealing area and a parking area both defined on the inner wall and both positioned below the vessel opening. The lid comprises a lid base having an inside surface, and a plug projecting from the inside surface of the lid base. The plug is configured to be inserted through the vessel opening to engage the parking area to define a parking position, and configured to be further inserted through the vessel opening out of the parking area to bias against a portion of the sealing area to define a sealing position. The first latching device comprises a first latching element positioned on the inner wall of the vessel, and a second latching element positioned on the outside of the plug.
