Abstract
A photographic film cassette has a cassette shell which is constituted of a pair of resin molded shell halves joined together to enclose a roll of photographic filmstrip therein. A film passage slot is formed along an axial joint between the shell halves for allowing the photographic filmstrip to advance to the outside of the cassette shell. Two fasteners are disposed on opposite sides of the film passage port for fastening the axial joint. Each fastener is constituted of a hook and a retaining portion which are formed integrally with one and the other shell halves, respectively. The hook is resiliently engaged with the retaining portion, and secured to the retaining portion by ultrasonic welding. In the welded position, the hook presses the retaining portion in a direction to secure the shell halves to each other.
