Abstract: A vent is described, more specifically a vent for the egress of fluid. The vent comprises a housing comprising an opening and at least one valve that extends through the housing. Additionally, the vent includes a plurality of baffles within the housing, where each baffle in the plurality of baffles comprises at least one aperture, and wherein the aperture or apertures of a first baffle within the plurality of baffles are offset from the aperture or apertures of a second baffle within the plurality of baffles. In this way, the egress of various fluids though the housing may be controlled.

Abstract: A system for shipping liquids is disclosed which comprises a container (12) which consists of two identical shells (16) the upper one of which is inverted with respect to the lower one. Toggles (32) and latches (34) are provided for pulling the two shells (16) together. The container rests on a frame, which includes pipework (44) for connecting to an inlet/outlet (26.1) in the base of the lower shell of the container. The equivalent inlet/outlet in the top of the upper shell of the container receives a gas escape vent (52). A flexible tank (46) is provided in the container (12) and the inlets/outlets communicate with the interior of the bag. The frame can, instead of accommodating just one container, be configured to support two, three or more containers in a side-by-side array.
