Abstract

A metered serving dispenser of cup-strength quantitites of granular material, having few parts, that may be erected as a free-standing device, or hung from an overhanging surface or mounted on a vertical surface, such as a wall, to dispense dried powders and granulated foods into a container, such as a cup, for mixing with water for ingestion.

Claims

1. A metered serving dispenser of cup-strength quantities of granular material comprising:

a) a granular material container comprising contiguous container walls and having a large, open end surrounded by an outwardly extending flat surface forming a flange;

b) a horizontally arranged dispenser housing including an upwardly-facing flat, support surface, for receipt of said container flange in sealing engagement therewith;

c) a support, including a C-shaped, curved member, for sliding engagement over a portion of said container flange and dispenser housing support surface, when in mutual sealed engagement, for retaining them in sandwich-like sealed engagement, and further including means extending from said curved member for mounting said dispenser in either a free-standing configuration, or under an overhanging surface, or against a vertical surface;

d) said housing having formed therein a shallow chamber bounded by a descending perimeter wall and a chamber closure plate mounted to said housing, below said chamber, said plate having a drop hole formed therein, opening from said chamber to below said housing;

e) a disk-shaped element removably retained in said chamber, for rotative movement therein, and having a plurality of vertically disposed measuring and dispensing apertures formed therethrough and arranged in a circle concentric with said element;

f) a plurality of short levers extending outward from said disk-shaped element into said chamber for manipulation, one at a time, through a slot formed in said descending perimeter wall, for advancing one of said measuring and dispensing apertures into registration with said drop hole; and

,

g) a feeder extending upward centrally from said housing, comprising;

i) an upwardly extending outer wall terminating at a rim spaced above said housing, said wall arranged to mate in sealing contact with the inner surface of said container adjacent said flange; and

,

ii) a funnel-shaped inner wall, slanting downwardly and inwardly from said rim to form an opening through said housing into said chamber, to direct the granular material from interior said container into said measuring and dispensing apertures in said disk-shaped element and wherein a portion of said inner wall extends over said measuring and dispensing element and terminates slightly above said element to level the granular material to the top of said dispensing aperture before said dispensing aperture is rotated into registration with said drop aperture.

2. The dispenser of claim 1 wherein said container is transparent.

3. The dispenser of claim 1 wherein said container has a substantially square cross-section.

4. The dispenser of claim 1 wherein said upwardly-facing flat support surface is narrow.

5. The dispenser of claim 1 wherein said upwardly-facing flat support surface is narrow and defines the outer edge of said housing.

6. The dispenser of claim 1 wherein said support means includes apertures formed in said extensions for use in fastening said housing to an overhanging surface or a vertical surface.

7. The dispenser of claim 1 wherein said horizontal housing is in rectangular shape and said C-shaped, curved member extends to three sides of said joined flange and supporting surfaces.

8. The dispenser of claim 1 wherein said horizontal housing is in square horizontal shape and said C-shaped, curved member extends to three sides of said joined flange and supporting surfaces.

9. The dispenser of claim 1 wherein said chamber is formed centrally in said housing.

10. The dispenser of claim 1 wherein said closure plate is mounted to said housing with removable fasteners.

11. The dispenser of claim 10 wherein said fasteners are screws.

12. The dispenser of claim 1 wherein said drop hole is not smaller than said measuring and dispensing aperture.

13. The dispenser of claim 1 wherein said drop hole is the same size as said measuring and dispensing aperture.

14. The dispenser of claim 1 wherein said drop hole is located at the front of said housing.

15. The dispenser of claim 1 further including circular seals between said closure plate and said disk-shaped element to prevent escape of granular material from said housing.

16. The dispenser of claim 1 further including circular seals mounted to said disk-shaped element to prevent escape of granular material from said housing.

17. The dispenser of claim 1 further including a first protuberance extending from the front of said housing, adjacent said slot, for aid in manipulating said levers across said slot during dispensing of said granular material.

18. The dispenser of claim 17 further including a second, ramp-shaped protuberance formed on said first protuberance for temporary engagement by a like ramp-shaped protuberance formed on the mating surfaces of said levers during the dispensing operation to provide an audible "click" indicating the dispensing operation has been completed and prevent reverse rotation of said disk.

19. The dispenser of claim 1 wherein said outer wall engages an inset formed in said container wall adjacent said flange to increase the sealing between said feeder and said container.

20. The dispenser of claim 1 further including:

a) a cover door pivotally mounted under said cover plate for closing over said drop hole;

b) an offset weight attached to said cover door to urge said cover door into closed position against the underside of said drop hole; and

,

c) a downwardly angled trigger attached to said cover door, spaced apart from said offset weight, to pivot said cover door downward and away from said drop hole by horizontal movement of a cup or other container thereagainst.
