Open the CIPO recordAbstract From the Canadian patent
An end closure cap for a tape sealed assembly with a cylindrical shell. The closure cap is characterized by a deep dish construction having a high degree of dimensional adaptability making it particularly suited for use with composite shells manufactured with relatively wide dimensional tolerances. The cap includes flared and beveled surfaces which make it self-aligning to the shell and elements which, until completion of the application of a sealing shrink tape, allow escape of air from the shell to facilitate high speed automatic closing of the assembly.
