Abstract

The invention provides discrete means for temporarily covering a substantially annular U-shaped effusive material container for use in a cathode ray tube. The annular covering member is likewise substantially U-shaped and, being of smaller dimensioning, is telescopically fitted within the container to cover the effusive material disposed therein. The inner and outer walls of the channeled cover are contiguous with the respective walls of the container to form the two concentric laminated composite walls of the assembly. The laminated components comprising each wall are joined in an interlocking manner by a substantially continuous annular deformation of the respective composite wall structure thereby effecting positive securement of the cover to the container.
