Molten glass transporter, transport cup, endcap, and methods

Abstract

A molten glass transport cup includes a conduit having an inlet and an outlet, and an endcap to cover or close, and uncover or open, the conduit outlet. The cup also may include a fluid exhaust outlet between the conduit and the endcap, and one or more fluid supply passages having one or more interior inlets located radially inwardly of the exhaust outlet. A molten glass transporter may include the cup and a conduit carrier including a sleeve at least partially circumscribing the cup. A related method may include receiving a molten glass charge in the cup in contact with an inner surface of the conduit, supplying fluid into the cup to displace at least a portion of the glass charge away from the transport cup, controlling an amount of the fluid between the charge and the transport cup, and moving the endcap to permit the charge to exit the conduit.
