Abstract
A cassette for holding and rotatably dispensing a roll of web material carried on a rotatable roll is provided with a locking member connecting between the rotatable roll and the cassette body and having a cross-sectionally reduced zone that may be ruptured by rotation of the roll incidental to the initial withdrawal of the web material from the cassette, the reduced zone having at least one inner sub-zone of lesser rupture resistance than the outer sub-zones on each side thereof, e.g., an aperture whereby the reduced zone ruptures upon rotation of the roll through a lesser angle than in the absence of the sub-zone.
