  • Patent number: 5072997
    Abstract: Dispensers for dispensing condiment packages and other articles. Such dispensers feature a front surface that contains a vertical succession of openings. Each opening dispenses a particular type of article, and is fed with articles that are supported by a curved floor that extends from adjacent the bottom of the opening upward and backward to the top area of the dispenser. The top surface of the dispensers may be positioned to open easily and thus allow easy access for loading and cleaning. The resulting dispensers economize on counter space, maintenance costs, and cleaning costs, and present condiment packages and other articles in an attractive, functional fashion.
