Abstract:
1. A self-venting spout comprising: an elongated spout housing comprising: a slidable sleeve in said interior passageway that is slidable parallel to said longitudinal axis, said slidable sleeve comprising a generally tubular portion having an outer surface with a first annular seal and an inner surface defining a sleeve passageway and having a second annular seal; wherein, when said slidable sleeve is in a spout-closed position, said first annular seal contacts and seals against said sealing ridge of the spout housing, and said second annular seal contacts and seals against said stopper; wherein, said spout comprises partition walls dividing said interior passageway into an air-flow passageway portion and a liquid-flow passageway portion, and wherein, when the slidable sleeve is in the spout-closed position, said sealing of the first annular sleeve and the sealing ridge blocks said liquid-flow passageway portion and said sealing of the second annular seal and the stopper blocks said air-flow passageway portion; and wherein, when said slidable sleeve is slid longitudinally to a spout-open position, said first annular seal is distanced from the sealing ridge to open said liquid-flow passageway portion and said second annular seal is distanced from the stopper to open said air-flow passageway portion.
