  • Patent number: 6334544
    Abstract: A napkin dispenser includes a housing having upright walls and a floor together forming a vertical compartment for the reception of a vertical stack of horizontal paper napkins. A horizontal slot is formed between the floor and a lower end of a front wall of the housing. That slot communicates with a lower portion of the compartment for facilitating the simultaneous removal of a bunch of napkins from the compartment. The positioning of a user's fingers above and beneath a selected number of napkins to be removed is facilitated by providing a vertical slot extending upwardly from the midpoint of the horizontal slot, and a finger notch formed about midway in a front edge of the floor.
