  • Patent number: 4759510
    Abstract: A scent-emitting toilet paper roller designed to fit into any rolled paper dispenser. The roller includes three components molded of thermoplastic material. Two of these components are identical vented hollow closed ended generally cylindrical roller halves, each half containing tongues and slots which permit the two roller halves to be axially slidably joined together. The third thermoplastic component is a helical coiled spring designed to fit inside the joined together roller halves and urge the two halves into their maximum axially extended position. A recessed truncated conical projection axially centered on the closed end of each roller half fits the assembled roller into any rolled paper dispenser. A quantity of scent-emitting pellets are contained within the hollow interior of the joined together roller halves to be tumbled about as the roller is rotated by the removal of paper, thus causing scent to be emitted into the atmosphere through vents in the roller.
