ABSTRACT:
A film cassette comprises a cassette shell and a film spool rotatably supported inside the shell. The spool has one end accessible from outside the shell for engagement to rotate the spool. An end cap is sized and shaped to cover the one end of the spool and can be removed from the shell to uncover the one end by pushing against a lip-like portion of the end cap that protrudes from the shell. A tamper-proof label is affixed to the shell and the end cap which is torn along a series of perforations when the end cap is separated from the shell.
