Abstract: A rectangular cathode-ray-tube envelope including a funnel member, component or part formed with sidewalls which flare outwardly from a circular small end of the member or component through a transition region of the member near the small end thereof to a substantially rectangular large end of the component or member. The sidewalls in the transition region of the funnel member or part deviate somewhat from their usual circular crosssectional configuration and are formed with cylindrically curved portions thereon so that cross sections taken in the transition region in planes lying parallel with the ends of the member have generally oblate configurations with substantially straight line opposed sides.
