<p>The spool (12) of a cartridge or cassette (10) of web material is locked against rotation during shipping and handling by a "one-shot" locking member (20, 61) which has a fixed portion (25, 65) and a movable portion (24, 62) joined along a bendable connection (30, 66). The movable portion (34, 62) is in engagement with a locking gear (22, 60) on the spool (12) while the fixed portion (25, 65) is mounted on the body of the cartridge. The locking member is released by bending the movable portion about the connection (30, 66) and stressing the material of the connection beyond its elastic limit.</p> |
