Closure usable for dispensing tear off lengths of rolled sheet materials, including plastic trash can liners. A 'roll top' door is included which incorporates in it a roller mechanism. The lower supporting body of the apparatus also has provided a roller mechanism. When the roll top door is closed, the roller on the door is brought into contact with the roller on the apparatus. When used, the door on the apparatus is opened and a store of sheet material to be dispensed is placed within the apparatus. An amount of sheet material to be dispensed is played out over the lower roller. When the door of the device is closed, the top roller is brought into contact with the upper surface of the sheet material to be dispensed. The friction between the upper and lower roller provides tension on the sheet material when sheet material is pulled from the apparatus.
