Yasso U.S. Pat. No. 1,919,582 discloses a funnel attached to a cover, wherein the funnel terminates above the bottom of a container.
The measuring funnel of Yasso U.S. Pat. No. 2,704,623 extends to the bottom of the container.
Sawyer et al. U.S. Pat. No. 1,233,812, Rauen U.S. Pat. No. 1,297,244, and Horvath U.S. Pat. No. 1,642,678 disclose funnel shaped devices near the top and a cup device therebelow.
The remaining patents disclose funnel devices attached to the cover.
Many of the prior patents disclose covers with funnels which extend deeply into the container. When the container is initially filled with material, it is difficult to secure the cover because the funnel must be forced down into the material. Other patented devices utilizing funnels which do not deeply extend into the container are not too effective for its intended purpose.
SUMMARY OF THE INVENTION
It is an object of this invention to provide a novel dispensing device in which the dispensing operation may be effective in several different ways, such as for example, by sifting, by pouring a predetermined quantity, or by pouring any desired quantity of material.
Another object of this invention is to provide a novel dispensing unit for a container, in which a selective dispensing operation may be performed, wherein the dispensing unit extends into the container a sufficiently small distance so as to facilitate its engagement with the container when the container is filled with material.
With these and other objects in mind, a dispensing device for a cylindrical container in accordance with the invention includes a substantially cylindrical cup having a closed bottom and a serrated flared top. The outer diameter of the serrated flare and the inner diameter of the serrations are such that the flared top rests on the rim of the container forming passageways to the interior thereof via portions of the serrated flared top. A circular cover, removably mounted on the container in cooperating relation therewith, holds the cup in place. The cover has central and off-center discharge openings therein. A measuring funnel, coupled to the cover, communicates with its central opening. The funnel has a plurality of spaced inlet notches at its lower end which rests on the bottom of the cup. A valve controls the openings. The valve includes a disk which closes the openings, which disk is rotatably secured to the cover at a point between the two openings. The disk has an opening therein for selective registry with the first named openings.
In accordance with specific features of the invention, a portion of the disk projects beyond the cover for manual actuation. As per another feature of the invention, the dispensing device includes the cylindrical container in cooperating relationship with cup, cover, funnel, and valve.
In specific features of the invention, wherein the rim of the container has an inner diameter di and an outer diameter do, the serrated flare has an outer diameter fo, and the serrations have an inner diameter fi, the relationships do ≥ fo> di and di>fi are valid. Another feature of the invention includes a measuring device wherein the cup extends into the container a distance less than one-fifth the height of the container.
In accordance with a specific embodiment of this invention, the cover has an internal female screw thread, and the container has an outer male thread near the rim for engagement with the thread of the cover. The container has a circumferential bead formed on its outer surface below the thread so as to appear to form a limit for the cover immediately therebelow. The cup extends into the container to a depth in proximal alignment with the bead.

DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to the drawings, especially FIGS. 1 and 2, there is shown a cylindrical container 10 having a rim 11 at the open end thereof. The cylindrical container 10 near the rim 11 is furnished with an external male thread 13 in the usual fashion. Below the male thread, circumferentially disposed about the external surface of the container 10, is a bead 14. The container 10 is preferably transparent and can be formed of suitable material such as glass or plastic.
The invention is directed to a dispensing device which, in one form, includes the overall combination depicted in the drawings including the container 10, and, in another form, can include the various components excluding the container 10. The dispensing device is depicted generally by the reference numeral 16 to include the overall device including, inter alia, the container 10.
Referring to FIGS. 2 and 6 especially, there is depicted a cylindrical cup 17. The cup 17 is closed at its bottom 18. The cup has a serrated flare 19 at the top thereof. The outer diameter of the serrated flare has a dimension fo as depicted in FIG. 6. The inner diameter of the serations has a dimension fi as shown in FIG. 6. Referring to FIGS. 1 and 2, the cup 17 rests on the rim 11 of the container 10, thereby forming passageways to the interior of the container 10 via portions of the serrated flared top 19.
The dimensions of the container 10 are such that the outside diameter of the rim 11 has a dimension do, while the inside diameter of the rim 11 has a dimension di.
The cup 17 has dimensions with respect to the rim 11 such that the outer dimension of the serrated cup fo is equal to or less than the outer dimension do of the rim 11. The dimension fo, however, is greater than the inner dimension di of the rim 11. The serrations are such that the inner dimension fi is less than the inner dimension di of the rim 11 so as to provide for the passageways.
A screw threaded circular cover 21 is provided having an internal female thread 22 adapted to engage with the male thread 13 of the container 10. The circular cover 21 is removably mounted on the container 10 in cooperating relationship so as to hold the cup 17 in place therewithin. The cup 17 can be frictionally held by the cover 21 against the wall 20 thereof. The cover 21 has a central discharge opening 23 and an off-central discharge opening 24 therein.
A measuring funnel 26 is connected to the cover 21 and communicates with the central opening 23 therein. The funnel 26 has a plurality of spaced inlet notches 27--27. Upon engagement with the cup and container, the bottom of the funnel 26 touches the bottom 18 of the cup 17, as shown in FIG. 1.
A valve controls the openings 23 and 24. The valve includes a disk 31 for closing the openings and is rotatably secured to the cover 21 at a point 32 between the two openings 23 and 24 so as to provide for selective registry with the openings.
The cover 21, in addition to being provided with the discharge opening 23 in register with the measuring funnel 26, and the circular pouring opening 24, is further provided with a group of sifter openings or apertures 33. The pouring opening 24 as well as the sifter apertures 33 communicates with the interior of the container 10 in a fashion that is exterior to the funnel 26 but interior to the measuring cup 17. Thus, the sifter openings 33 and the opening 24 communicate with the large interior portion of the container 10 via the serration 19 passageways of the cup 17.
The combined valve or dispensing selector and closure disk 31, which is pivoted at 32 to the top surface of the cover 21, has an edge portion thereof which projects outwardly beyond the marginal edge of the cover 21 so that the disk may be easily rotated.
The pivot 32 on the disk 31 is located eccentrically on the cover 21 and is equidistant from the center of the group of apertures 33 and the respective centers of the openings 23, 24, so that, by rotating the disk 31, a discharge opening 34 formed in the disk 31 may be brought in register selectively with the openings 23, 24 or group of apertures 33, as best shown in FIGS. 3,4, and 5.
The bottom of the measuring cup, when the entire unit is assembled as depicted in FIG. 1, is in proximal alignment with the bead 14 of the container 10 as shown in the drawing.
When in use, the container 10 is filled with sugar or some other material up toward the bead 14. When assembled, as depicted in FIG. 1, the device 16 may be immediately used for sifting material via the apertures 33 or for pouring the desired quantity via the aperture 24. The material will pass from the interior portion of the container 10 through the serrated passageways at 19 and through the respective apertures 24, 33.
After one such use, or, alternatively, when the disk 31 is closed and the container 10 is inverted, the material, upon the inversion of the dispensing device 16 and the uprighting of the container 16, the measuring cup 17 becomes filled. This action takes place because, upon inverting, a quantity of sugar, for example, passes through the passageways at 19 and fills a volume which exists between the serrated top 19 of the cup 17 and the top of the cover 21. Upon uprighting of the container 10, the material previously in the volume between the top of the flared cup and the top of the cover 21 will settle into the measuring cup 17 and reside there.
When it is desired to pour a predetermined quantity of the material for example, one teaspoonful, the disk 31 is rotated so that the aperture thereof at 34 is in registry with the opening 23 of the cover 21. The material held in the cup 17, entrapped by the funnel 26, passes through the spaced inlet notches 27 of the measuring funnel 26 and is discharged out through the aperture 23 of the cover and the opening 34 of the disk. Thus, with the disk 31 located so that the discharge opening 34 is in register with the outlet opening 23, the device may be inverted and the measured amount of sugar poured outwardly from the cup 17 through the funnel 26. However, when it is desired to pour an unlimited quantity of sugar from the container, the disk 31 is rotated so that the discharge opening 34 registers with the pouring opening 24 as shown in FIG. 4. Alternatively, by rotating the disk 31 so that the discharge opening 34 is in register with the group of apertures 33, the sugar may be sifted out of the container, as shown in FIG. 5.
When the disk is rotated so that the discharge opening 34 is disposed at a point diametrically opposed to the sifter openings 33 with respect to the pivot 32, the disk covers the openings 23, 24 and 33 and the device is closed. When the container 10 is to be refilled, the cover 21 is simply removed therefrom, the cup 17 is removed, and sugar is added to the container up to the bead 14.
Thus, an empty container 10 can be filled to the bead 14, the cup 17 can be frictionally held within the cover 21 against the interior wall 20 thereof, and the cover 21 screwed on top of the container so as to form an integral dispensing device 16.
In accordance with one embodiment of the invention, by way of example only, the container 10 may be constructed of glass or plastic and have an inner diameter of 2 5/16 inches and a total height of 4 7/8 inches. The container 10 has usable interior height up to the bead 14 of 37/8-inches. Thus, the container 10 can easily hold 14 cubic inches of material. The measuring cup can have a depth of three-fourths inch and an outer serrated flare d top of 2 1/2 inches with the inner serrations of 2 1/8 inches.
Various modifications may be performed without departing from the spirit and scope of this invention. For example, alternatives contemplated within the scope of the invention include fastening means of the cover with respect to the container 10 other than that of the screw threads.
