Abstract
Abstract Fluted coffee or other beverage filters, generally formed of paper, or paperboard, are so stacked in containers in which they are sold that it is not easy to lift off and remove a single filter paper for application. The practice has been to transfer the filters to a dispenser therefor, but generally such dispensers are fabricated of a polymer material, are reasonably expensive, and are not for disposable usage, or ease of application. Herein, the container and beverage filter dispenser of this invention may be solid and marketed with a supply of filters, and thrown away after application and usage. In addition, the invention contemplates a blank from which the container, and spring for biasing the filters upwardly within the container, may be fabricated.
