ABSTRACT:
TV bulbs are composed of funnels and panels, and the present invention sets forth a novel construction of a funnel for a TV bulb which not only incorporates thinner walls than a conventional funnel, but which also utilizes less total glass when formed into a bulb than a conventional TV bulb, while retaining the required strength and sealing surface area necessary to form an evacuated TV tube when sealed to a viewing panel.
