A vented closure is provided for use on a liquid container. The body of the closure (16) includes a dispensing port and a vent (28) extending therethrough with the vent adjacent the dispensing port (26). The tube (32) extends through the dispensing port (26) and has a flange (38) extending laterally therefrom, engaging the outer surface (20) of the closure body. A flexible seal (40) member is positioned on the tube (32), spaced from the inner surface (28) and having a frusto-conical shape where the inner end (40a) of the member is formed at the tube (32). The outer end (40b) is spaced away from the tube (32) and engages the inner surface (28) of the closure body (16), forming a hollow area (41) between the member (40) and the tube (32). The flexible seal member (40) is movable radially away from the tube (32) and away from the inner surface (28) to the inflow of air through the vent and over the flexible seal member (40).
