A dispenser for a roll 92 of sheet material of a pre-determined axial length. The dispenser having a body 12 and a mount 50 for mounting a roll within a region defined by the body, the mount comprising first and second mounting members pivotable relative to each other to define a loading position and an operative position. The mount is biased to the loading position. In the loading position, the first mounting member is angled to define a space between the first mounting member and a location corresponding to the position of the second mounting member larger than a pre-determined axial length. In the operative position, the first mounting member is angled to define a space between the mounting members of the preÂdetermined axial length. In use, insertion of a roll of a pre-determined length pivots the first mounting member from the loading position to the operative position so as to mount the roll in the dispenser. Preferably, the dispenser comprises a blocking mechanism 86, 88 for preventing a portion from moving into a position to enable the dispenser to function when a roll of the wrong length is positioned in the housing. A dispenser comprising a blocking mechanism and a dispenser comprising a formation which impedes rotation of the roll if a roll not of a predetermined configuration is incorrectly mounted are also disclosed. |
