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.

Claims

1. In combination:

a plurality of interfitted cuplike face masks, each mask having a certain cross-section presenting a generally parabolic nose-receiving region and a generally circular mouth-receiving region, and each mask including a strap secured adjacent opposite marginal edges of said mouth-receiving portion;

an elongated container for receiving said interfitted masks and comprising continuous sidewalls circumscribing said masks and defining a mask-receiving passageway; and

retaining means secured transversely across said passageway and including structure defining a mask-dispensing aperture of the same general cross-sectional configuration as said mask cross-section, said masks being disposed in said passageway adjacent said retaining means with the strap of the one mask adjoining said retaining means extending through said aperture such that said masks are serially dispensed by pulling on the strap of said one mask, said one mask being removed from said container with the remaining masks being retained in said container and the strap of the next mask exposed in said aperture.

2. An invention as set forth in claim 1, said retaining means including a depending inwardly converging wall defining said aperture.

3. An invention as set forth in claim 2, said depending wall having an inwardly extending lip adjacent the distal end thereof.

4. An invention as set forth in claim 1, said retaining means including a depending wall structure having an uppermost portion secured adjacent said aperture defining structure and a lowermost, inwardly converging portion.

5. An invention as set forth in claim 4, said uppermost portion of said depending wall structure defining a cross-section approximately equal to said certain cross-section of said mask and said lowermost portion defining a cross-section proportionately less than said certain cross-section of said mask.

6. An invention as set forth in claim 5, said depending wall structure including a continuous, inwardly-extending lip adjacent said lowermost portion.

7. An invention as set forth in claim 6, said certain cross-section of said mask presenting a first, generally circular mouth-receiving region and a second, generally parabolic, nose-receiving region adjoining said first region, said second region having a smaller cross-sectional area than said first region.

8. An invention as set forth in claim 7, the perimeter of said parabolic, nose-receiving region of said mask presenting an apex, bridge-of-the-nose section and a pair of converging side sections separated by said apex section, said lip extending inwardly a greater distance in the vicinity of said side sections and a lesser distance in the vicinity of said apex section for permitting ease of removal of a respective mask.

9. An invention as set forth in claim 1, said container comprising a box being rectangular in transverse cross-section.

10. An invention as set forth in claim 1, including means for hanging said container from a hook.

11. An invention as set forth in claim 1, said retaining means presenting a generally planar engagement surface.

12. In combination:

a stack of interfitted cuplike face masks, each mask having a certain cross-section presenting a generally parabolic nose-receiving region and a generally circular mouth-receiving region, and each mask including a strap secured adjacent opposite marginal edges of said mouth-receiving region;

an elongated container for receiving said stack of interfitted masks and defining a mask-receiving passageway; and

mask retaining means carried by the container and engaging the lowermost mask of said stack to releasably retain the lowermost mask of the stack and thereby the remainder of said stack in the container, said masks being disposed in said passageway adjacent said retaining means with the strap of said one lowermost mask adjoining said retaining means extending through said aperture, said retaining means being configured such that when a user pulls downwardly on the strap of said one mask, said one mask being removed from said container initially tilts as the nose-receiving region is pulled free of the remaining stack and any retaining means therefor and then the remainder of said one mask is freed from the retaining means to assure dispensing of said masks one at a time as the remaining masks are retained in said container and the strap of the next adjacent mask extends downwardly from the container below the retaining means for grasping by a user.
