Claims

[Claims for Utility Model Registration] (1) Forming a thick funnel that is sealed with fritted glass to the panel constituting the envelope;
A cathode ray tube configured such that the funnel accounts for 40% or more of the total weight of the panel and the funnel. (2) The part of the funnel that continues from the sealing surface with the panel is made thicker, and the outer surface of that part is formed into a flat curved surface that is approximately parallel to the tube axis, so that an explosion-proof band can be attached to the flat curved part. A cathode ray tube as set forth in claim (1) of the utility model registration claim.
