摘要：
A cassette for holding and dispensing a roll of web material that is provided with locking means for preventing rotation of the roll prior to initial withdrawal of material from the roll, the locking means being formed by a generally rigid locking member with one end portion frictionally engaged within the core of the roll, and the other end portion non-rotationally connected with a cassette end wall, and a weakened zone interconnecting those end portions, and adapted to rupture upon rotation of the core incidental to the initial withdrawal of material from the roll.
