Abstract: An anti-misuse system for a sheet dispenser having a roll of sheet material and a housing to receive the roll. The anti-misuse system includes an end portion of a roll incorporating a first projection and a corresponding end wall portion of the housing comprising a retracting portion incorporating an interacting mechanism. The retracting portion is movable between a deployed position in which the interacting mechanism affects the functionality of the sheet dispenser and a retracted position in which the interacting mechanism enables the sheet dispenser to be functional. The retracting portion further incorporates an abutment drivable by the projection upon insertion of the roll into the housing to move the retracting portion into the retracted position.

Abstract: A reel dispenser includes a housing, a coupling associated with a reel and a mounting for removably mounting the coupling to the housing so that the coupling is movable between a mounted and a dismounted condition. The coupling includes a key. The mounting includes a lock arrangement which is movable between a locked condition and a free condition. The reel dispenser is arranged so that when the coupling is moved from the dismounted condition to the mounted condition, the key moves the lock arrangement to the free condition, permitting rotation of the coupling relative to the housing.

Abstract: A dispenser for a roll of film material, comprising a cutting arrangement for cutting polyethylene having an upper portion and a lower portion, the upper portion being configured to move in relation to the lower portion between an open position and a cutting position. One of the upper portion and the lower portion comprises a blade, and the other of the lower portion and the upper portion comprises a cutting channel defined by a first pair of legs. The legs include at least one surface configured to reduce slip of film material across that surface.
