RmmmwEFQd t$uvuvv a E n INVENTOR WILLIAM J HAFNER BY QMaW ATTORNEY This is a continuation of application Ser. No. 132,642, filed Apr. 9, 1971, now abandoned.

This invention relates to dispensing apparatus, more particularly the invention relates to dispensing shot-like or pellet dispensing apparatus.

It is an object of the invention to provide a novel pellet dispensing apparatus for easily and rapidly dispensing apparatus for easily and rapidly dispensing single shot-like pellets from a bottle one at a time under a gravity flow. I

It is a further object of the invention to provide a novel dispensing apparatus which will accurately and easily dispense a quantity of pellets one at a time.

It is a further object of the invention to provide a novel dispensing apparatus which will dispense pellets from a bottle one at a time.

Further objects and advantages of the invention will become apparent as the description proceeds and when taken in conjunction with the accompanying drawing wherein:

FIG. 1 is a side elevational view of the sugar pellet dispensing invention.

FIG. 2 is a front elevational view of the sugar pellet dispensing invention.

FIG. 3 is an enlarged fragmentary cross-sectional view taken along line 3-3 of FIG. 2 illustrating the interior construction of the pellet or shot-like dispensing invention.

FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. 3.

Briefly stated, the invention comprises a pellet or shot-like dispensing apparatus for dispensing pellets one at a time out of a tube from a bottle, having an elongated tube with a cap portion fixed thereto at an upward angle, said cap being threaded onto the mouth of a bottle, said tube has a hollow interior with said cap and tube having a bore providing communication between the bottle and the tube and plunger mounted in the tube, a spring rod mounted to the tube having a laterally bent and projecting into an opening in the tube below the opening in the cap to the bottle, whereby the bent end of the rod will hold only one pellet in the tube at a time; pellets in the bottle which will roll from the bottle down the bore in the cap and tube into the tube one at a time, a plunger slidably mounted in the tube acting more downward and push the pellet in the tube downward with the pellet forcing the bent end of the spring rod out to enable the pellet to slide or slip past and drop out the bottom of the tube, spring means returning the plunger to its upward position after pushing the pellet past the bent end of the spring rod so that another pellet may roll into the tube where it may be forced downward past the bent end of the spring rod and out the tube by the plunger.

Referring more particularly to the drawing in FIGS. 1 and 3 the sugar pellet dispensing invention 20 is shown threaded onto the threaded mouth reduced collor parts 21 of a conventional bottle 22.

The dispensing invention 20 has an annular cap 29 to thread over the mouth 21 of the bottle. The dispensing invention has a tubular member 23 fixed to the cap 29 and the tubular member 23 has a cylindrical inner bore 24. A plunger 25 has a cylindrical outer surface 725 and the plunger 25 is slidably mounted in the cylindrical bore 24. The upper end of the tube 24 has an enlarged tubular portion 26 with an enlarged cylindrical inner bore 27. A coil spring 28 is slidably mounted coaxially over the plunger 25 within the enlarged bore 27.

The upper end 30 of the cylindrical plunger projects upward through a bore 31 the upper end of the tube 23. An annular ring 32 is fixed to the pluger 25 and projects outward therefrom within the enlarged bore 27 of the enlarged tubular portion 26, above the coil spring 28. The lower end 33 of the plunger has a spherical recess 34, so that the outer lower edges 33' project and taper downward to form a knife like edge.

A spring rod 35 has a laterally bent lower end 36 which projects freely through a hole or bore 37 in the tube 23 and extends centrally across the inner bore 24 of the tube. The upper end 38 of the spring rod 35 is wrapped around the tubular member 24 so as to lock the upper end of the spring rod to the tubular member.

The cap 29 has a cylindrical bore 39 which communicates at its upper end 39' with the opening 40 in the mouth 21 of the bottle and it communicates at its lower end 39' with a bore 41 in the tube 24.

The plurality of spherical sugar pellets 42 are located inside the bottle. The pellets 42 are of the type used for decorating cookies and pastry and are made of sugar with a silver coating and are edible.

The pellets 42 have an outside diameter which is smaller than the bore 39 on the cap 29 and smaller than bore 41 into the tube and also smaller than the cylindrical inner bore 24 extending along the tube, so as to move or roll freely through the

bores

39, 41, and 24, under the force of gravity, so that pellets located in the bottle will roll one after another down the bore 39 through the bore 41 into the bore 24 where they will come to rest upon the laterally bent leg 36 of the spring rod. The

bores

39, 41, and 24 are only large enough so that the pellets 42 may move freely only one after another through the

bores

39, 41, and 24, as shown in FIGS. 1 and 3, and so that only one of the sugar pellet 42 will rest in the bore 24 tube 23, at a time as shown in FIGS. 1 and 3.

OPERATION The shot or pellet dispensing invention 20 operates as follows: The dispensing invention 20 will be mounted onto a bottle 22 having a plurality of shot-like sugar coated pellets 42 by placing the bottle 22 upright with the mouth 40 extending upward and then rotating the dispensing invention to thread the threaded cap 29 onto the threaded mouth or collar portion 21 of the bottle 22. whereupon the dispensing invention 20 with the bottle 22 attached thereto will be tipped to its position shown in FIGS. 1 and 3 and held over the cookie to be decorated and the operator will press the top of the plunger downward moving the plunger 24 downward from its position shown in solid lines to its position shown in dashed lines in FIG. 3 and designated by numeral 42. The recess portion 34 of the lower end 33 of the plunger as it moves downward will socket over the pellet 42' located in the tube 24 and the tapered annular knife like outer edge 33' will project between the pellet 42' and the next upward adjacent pellet 42" to separate them and prevent the pellet 42" from rolling into the tube 24.

The plunger will continue moving downward pushing the pellet 42' downward from its position shown in FIG. 3, and with the bottom of the pellet 42 engaging the lateral bent end of the spring rod and push the rod and bent end clockwise outward from its position shown in solid lines to its position shown in dashed lines and designated by numeral 42, which enables the pellet to slip past the bent end 36 of the rod and drop out the bottom 44 of the tube.

The operator will then release the plunger and the coil spring 28 will push the plunger back upward to its position shown in solid lines in FIGS. 1 and 3 as the lower end of the plunger moves upward past the lateral bent end 36 of thespring rod, the spring rod will be releaved and spring back to its position shown in solid lines in FIG. 1 and 3, and after the plunger has slid upward past the bore 41 to its position shown in solid lines in FIG. 3, the next pellet 42 may roll into the tube 24 to the position formerly where pellet 42 was located and the next pellet 42" will take the same position of pellet 42", before the plunger action. This only one pellet is located in the tube at a time for each plunger action. This process will repeat itself with pellets moving from the bottle down the bore 39 into the tube one at a time under gravity flow.

Thus it will be seen that a novel shot or pellet dispensing device has been provided which will dispense cylindrical pellets easily and rapidly from a bottle, under a gravity flow, accurately and one at a time by simply pressing the plunger at the top of the dispenser.

It will be obvious that various changes and departures may be made without departing from the spirit and thereof and accordingly it is not intended that the invention be limited to that specifically described in the specification or as illustrated in the drawings but only as set forth in the appended claims wherein:
