Vented closure

摘要

A vented closure (20) 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 (21) constructed and arranged for threaded engagement to the container. The threaded cap (21) defines a septum orifice (33) that is sized and arranged to receive a siphon tube. A gasket (22) is assembled into the threaded cap (21) for sealing the interfit between the vented closure (20) and the container. An elastomeric venting valve (23) is assembled into the threaded cap (21) and the venting valve (23) includes a septum (40) with a slit (40a) therein for receiving in a self-sealing manner the siphon tube. A retainer ring (24) is used to capture the venting valve (23) within the threaded cap (21) and a safety ring (32) in unitary combination with the threaded cap (21) retains the vented closure on the container. <IMAGE>
