A spout (20) for a lid (10), where the lid (10) is constructed and arranged to fit over and close an open top of a container (150). The spout (20) has an elongated fluid conduit (22) having two ends (24, 25) and lying along a conduit longitudinal axis (23). The conduit (22) has a pair of opposed convex curved sidewalls (61, 63) that meet at two opposed locations (64, 65) at an angle of less than 180 degrees to define a generally elliptical cross-sectional shape that has a major axis (51) that passes through the sidewall meeting locations (64, 65). |

1. A spout for a lid, where the lid is constructed and arranged to fit over and close an open top of a container, the spout comprising:
an elongated fluid conduit having two ends and lying along a conduit longitudinal axis, the conduit having a pair of opposed convex curved sidewalls that meet at two opposed locations at an angle of less than 180 degrees to define a generally elliptical cross-sectional shape that has a major axis that passes through the sidewall meeting locations; and a bite valve comprising a membrane located within the conduit and spaced from the ends of the conduit, the membrane coupled to both sidewalls so as to fully block the conduit, and a slit through the membrane, where the slit lies along a slit axis that is transverse to the major axis of the conduit. |
