Abstract
The present invention provides in combination, a supply roll comprising an elongate liner, a multiplicity of electrodes, and a coating of moist adhesive on the electrodes that releasably adheres the electrodes in spaced relationship along the liner, and a refillable air-restricting dispenser comprising a plurality of walls forming a housing. The walls comprise a hollow tubular peripheral wall, and first and second opposite end walls, and define a central cavity within the housing. The peripheral wall has a slot communicating between inner and outer surfaces of the peripheral wall. The slot is adapted to afford passage of the liner with electrodes adhered thereto. A shield is present which covers the slot, and an element mounts the shield on the housing for movement between an open position spaced from at least a portion of the slot to afford withdrawing the end portion of the liner with the electrodes adhered thereto through the slot, and a closed position over at least the portion of the slot adjacent the liner to restrict entry of air into the cavity. One of the end walls is removable to afford replacement of a depleted supply roll.
