  • Patent number: 12042099
    Abstract: A method for loading a stack of individual paper units into a dispenser includes inwardly pushing on a pair of oppositely disposed end portions of respective lateral walls of the dispenser, thereby releasing a drawer of the dispenser for sliding movement of that drawer relative to a remainder of the dispenser. The drawer includes first and second, oppositely disposed sidewalls, a bottom wall, and an arcuate front wall that has a dispensing aperture. The bottom wall of the drawer extends between the first and second sidewalls of the drawer, and the sidewalls of the drawer define an open end of the drawer opposite the bottom wall and, jointly with the bottom wall and arcuate front wall, defines a storage volume of the drawer. The drawer is slid outwardly relative to a remainder of the dispenser to thereby expose the first and second sidewalls and bottom wall of the drawer.
