Abstract
The invention provides a sealed effusive material structure for angular orientation within a cathode ray tube. The effusive material, which is disposed in an annular channelized container, is protectively sealed by a metallic covering that melts at a temperature above that encountered during panel-funnel sealing, and below that used for activation of the effusive material. Receptacle means integral with the container is provided to collect and retain the gravity flow of the melted covering material.
