ABSTRACT:
A venting closure assembly extending across an access opening on the top part of a milk tank. There is a venting closure member having perimeter flange members which fit against a support ring of the milk tank to form one or more circumferential venting channels. A cover having a vent opening fits over the closure member and engages the peripheral portions thereof to form a circumferential seal against the support ring. The venting channel or channels connect to circumferentially spaced openings on the flanges to provide venting from inside the tank to the area outside the tank, while preventing both spilling of the milk and contamination from outside sources.
