  • Patent number: 4550856
    Abstract: A compact dispensing device, especially useful in conjunction with disposable face masks, is provided which serves to store such masks and to serially dispense the masks in response to user demand. The dispenser preferably includes an elongated container in which the masks are stored and an apertured retainer secured across one end of the container. The retainer preferably presents a depending, inwardly converging sidewall around the aperture and the masks are interfitted such that the strap of the mask adjacent the retainer is positioned through the retainer aperture. The retainer aperture presents the same irregular cross-sectional configuration as the mask cross-section, with the masks being serially dispensed by simply pulling on the strap of the mask presented through the retainer aperture. In preferred forms, the depending sidewall has an inwardly-extending lip with the wall and lip cooperating to allow the masks to be singularly dispensed while retaining the remaining masks within the container.
