Abstract
A cassette shell consisting of a pair of shell halves, upper and lower, molded from resin. The cassette shell is disassembled to take out the exposed film for development. When the cassette shell is molded, molten resin is injected so as to form a weld line to encircle the circumferential surface of the cassette shell, along which line the cassette shell is broken by spreading a port portion with a jig. In a preferred embodiment, a groove is formed inside the cassette shell and serves for breaking the cassette shell. In another preferred embodiment, receiving recesses are formed on a juncture between the shell halves for receiving a disassembling jig.
