<p>A portable dispenser (10) with which lengths of a sheet material (12) may be manually dispensed from a supply roll (13) of the sheet material. The dispenser (10) has a frame (18) including a bridging portion (19) adapted to extend along a portion of the periphery of the roll (13) of sheet material, and end wall portions (22) fixed to the ends of the bridging portion (19) and adapted to extend along the opposite end surfaces of the roll (13) of sheet material on which the roll (13) of sheet material is rotatably journaled. A resiliently flexible cantilevered portion (24) of the frame (18) has a proximal edge (26) fixed to the bridging portion (19) and has a sharp cutting edge (30) along its opposite distal edge (28). A guard portion (32) of the frame (18) extends between its end wall portions (22) and has an inner surface extending along the side of the cutting edge (30) opposite the roll (13). The cantilevered portion (24) is normally positioned in a retracted position at which the cutting edge (30) is spaced from the roll (13) of sheet material and is positioned adjacent the inner surface of the guard portion (32) to restrict contact with the cutting edge (30) by a person handling the dispenser (10) such as to withdraw a length of sheet material (12) from the dispenser (10). The cantilevered portion (24) can be manually flexed by a person grasping the outer surface of the frame (18) to move the cutting edge (30) away from the inner surface of the guard portion (32) to a cutting position at which sheet material (12) being pulled from the roll (13) can be engaged with the cutting edge (30) to transversely sever the sheet material.</p> |
