Abstract
A vented closure for closing and venting a container with threaded engagement to a neck portion of the container for dispensing fluid from the container includes a unitary, molded plastic cap constructed and arranged for threaded engagement to the container. The threaded cap defines a septum orifice that is sized and arranged to receive a siphon tube. A gasket is assembled into the threaded cap for sealing the interfit between the vented closure and the container. An elastomeric venting valve is assembled into the threaded cap and the venting valve includes a septum with a slit therein for receiving in a self-sealing manner the siphon tube. A retainer ring is used to capture the venting valve within the threaded cap and a safety ring in unitary combination with the threaded cap retains the vented closure on the container.
