Abstract: An apparatus for feeding glass batch materials into a pool of molten glass within a furnace comprises a base disposed at a batch-feeding end of the furnace above the pool of molten glass. A hopper for dispensing glass batch materials is mounted on the base and includes an outlet disposed above the molten glass. A plunger assembly is mounted on the base and includes a reciprocable plunger and an actuator for reciprocating the plunger in a linear direction past the hopper outlet into and from the pool of molten glass at the location where batch materials are deposited thereon. The plunger includes a pusher face for pushing dispensed batch materials beneath the surface of the pool of molten glass. A barrier is disposed on a side of the hopper outlet opposite the plunger. The barrier extends into the pool of molten material to the lowermost extent of the pusher face so that batch materials submerged by the plunger travel beneath the barrier and are isolated from the batch depositing location.

Abstract: A cap for a molded plastic container has a cover section and a seating section which are provided with a tear strip for obtaining drinking or pouring access to the contents of the container without removal of the cap. The cover section has a centrally raised portion and a portion which slopes downwardly and radially outward from the centrally raised portion and terminates in a circumferentially extending seating portion. The latter includes an outer, downwardly extending skirt which embraces the upper end of the container. Two parallel slots extend part way up from the edge of the skirt and terminate in a groove which extends to the edge of the cover section and then follows the surface of the cover section in a generally radial direction to form a tear strip having a continuous, wedge-shaped configuration. The two parallel slots form a tab for grasping the tear strip with the fingers.
