Abstract:
1. A dispensing closure for a vessel containing fluid comprising a base member engageable with the vessel and a spout member defining a flow channel, the spout member engaged with the base member and pivotable relative to the base member from a closed position to a flow position for dispensing fluid from the vessel through the flow channel, one of the base member and the spout member including a rupture membrane and the other of the base member and the spout member having an actuator for rupturing the rupture membrane during pivoting of the spout member to the flow position to define a flow opening in said one of the base member and the spout member in fluid communication with the flow channel and to permit fluid flow through the flow opening and into the flow channel, the spout member defining a vent channel; wherein the vent channel includes two openings defined by the spout member, one of the openings in communication with the flow opening when the spout member is pivoted to the flow position and the other one of the openings in communication with the atmosphere to permit air to pass through the vent channel when the spout member is pivoted to the flow position; and wherein the rupture member is positioned adjacent said other of the openings and is configured to function as a check valve to prevent fluid from passing into said one of the openings when the spout member is pivoted to the flow position.
