Claim:
A dispenser usable with roll material, comprising: a base for facilitating connecting the dispenser to a mounting structure; first roll mounting structure disposed from a first side of the base, with the first roll mounting structure being capable of rotatably receiving a first end of a roll spindle; second roll mounting structure disposed from a second side of the base opposite the first side, with the second roll mounting structure being capable of rotatably receiving a second end of the roll spindle; roll spindle for receiving roll material to be dispensed from the dispenser, the roll spindle being rotatably disposed between the first and second roll mounting structures, with the roll spindle have a shape that is asymmetrical about a longitudinal rotational axis of the roll spindle; pressure member that has a proximal end rotatably connected to the base and a distal end extending over the roll material disposed on the roll spindle; at least one roll engagement member that extends from a surface of the pressure member toward the roll material disposed on the roll spindle, with the roll engagement member having a shape that will restrict a direction of rotation of the roll material such than in a first direction the roll material remains substantially undamaged and in a second opposite direction the roll material is subject to damage; and biasing member for biasing the pressure member toward the roll material on the roll spindle such that the roll engagement member remains in contact with the roll material at all points of rotation of the roll material on the roll spindle.
