As will be further described herein, dry food dispenser 100 is designed to dispense food, stored in storage receptacle 80, in portions in accordance with pre-determined quantities dependent upon the operation of dispensing apparatus 200.
Referring now to FIG. 2, there is shown a perspective exploded view of dispensing apparatus 200, showing base 10, cell holder 18, cassette 24, cell cover 28 and mixer 36.
Cylindrical base 10 has a hollow circumferential interior with a centrally disposed hub 11, and has a slidable handle 12 extending from hub 11 through and externally to wall 13 of base 10. The volume of the interior is defined by wall 13 and floor 17 (see FIG. 3A), with a dispensing aperture 15 formed in floor 17 on the bottom of base 10. As described further in FIGS. 3A-B, aperture 15 provides an exit of dry food dispensed from dispenser 100.
Base 10 further has connecting clips 14 disposed on both sides, and wall mounting bracket 16 for the option of mounting dispenser 100 on a wall.
Rotatable cell holder 18 is ring-shaped and is adapted to be seated within the hollow interior of base 10, and has a centrally disposed socket 22 for engaging hub 11 from above. Cell holder 18 has two cell apertures 20a-b formed therein for insertion of open-bottomed cells 26a-b of cassette 24. Cassette 24 may vary in the sizes of cells 26, ranging from approx. 5 cc per cell to approx. 35 cc. Wall 23 of cell holder 18 has slot 21 formed therein to accommodate handle 12 from within base 10, so that when handle 12 is slid from side to side, hub 11 rotates and cell holder 18 is rotated along with it.
Double-leveled cell cover 28 is placed over cell holder 18 and is used as a partition between the dry food in storage receptacle 80 above it and dispensing apparatus 200. Cell cover 28 is static and is seated over rotatable cell holder 18 via a centrally-disposed hole 29 accommodating socket 22 of cell holder 18. The partition of cell cover 28 is provided by the bottom level 30 which is formed with two cell openings 31a-b (see FIG. 5A). These openings 31a-b, enable dry food to fall through them and into cells 26a-b. Bottom level 30 is formed as a slanted surface with cell openings 31a-b positioned across from each other. The slanted surface of bottom level 30 directs the dry food into cells 26a-b. Top-level section 32 of cell cover 28 has two semi-rigid wipers 34 disposed vertically to bottom level 30. Lower edges of wipers 34 provide a wiping function for the purpose of assuring portion accuracy by wiping any excess dry food accumulated over cells 26a-b. Wipers 34 are semi-rigid and adapted to be flexible enough so as to avoid breaking hard granular food such as nuts, and rigid enough so as to avoid having the hard food jam the movement of cell holder 18. Cell cover 28 has a rim 35 which surrounds wall 23 of cell holder 18 when seated upon it, for preventing the food from spilling out of cell holder 18.
Seated over cell cover 28 is mixer 36 which connects to socket 22 via stem 38 inserted through hole 29. Wings 40 extend from stem 38, and they rotate with handle 12 sliding movement, thereby mixing the dry food in storage receptacle 80 for the purpose of avoiding agglomeration.
Referring now to FIG. 3A-B, there is shown cylindrical base 10 having a hollow circumferential interior with a centrally disposed hub 11 having a slidable handle 12 extending therefrom and protruding through a window 19 formed in wall 13 of base 10. Base 10 further has connecting clips 14 disposed on both sides, and wall mounting bracket 16 for the option of mounting dispenser 100 on a wall. The hollow interior is formed with dispensing aperture 15, as shown in FIG. 3B, on the bottom of base 10 for the exit of the dry food from dispenser 100. Cell holder 18 is seated in the hollow circumferential interior, as described in FIG. 4 herein below.
Referring now to FIG. 4, there is shown cell holder 18 having cell apertures 20a-b formed therein, for the insertion of open-bottomed cells 26a-b of cassette 24. Cassette 24 may vary the size of cells 26a-b each defining a pre-determined volume capacity. Cassette 24 is interchangeable with any other cassette having different cell sizes, according to the need and the specific dry food to be dispensed from dispenser 100.
Cassette 24 may be made of polypropylene or any other suitable material.
Referring now to FIG. 5A, there is shown cell cover 28, unattached to the other parts of dispenser 100. Cell cover 28 is double-leveled and is used as a partition between the dry food in storage receptacle 80 above it and dispensing apparatus 200. Cell cover 28 is static and is seated over rotatable cell holder 18 via a centrally-disposed hole 29 accommodating socket 22 of cell holder 18 (see FIG. 4). Cell cover 28 is provided by the bottom level 30 which is formed with two cell openings 31a-b. These cell openings 31a-b, enable dry food to fall through them and into cells 26a-b, when they are aligned. Bottom level 30 is formed as a slanted surface to direct the dry food into cells 26a-b. Top-level section 32 of cell cover 28 has two semi-rigid wipers 34 disposed vertically to bottom level 30. Lower edges of wipers 34 provide a wiping function for the purpose of assuring portion accuracy by wiping any excess dry food accumulated over cells 26a-b. Wipers 34 are semi-rigid and adapted to be flexible enough so as to avoid breaking hard granular food such as nuts, and rigid enough so as to avoid having the hard food jam the movement of cell holder 18. Cell cover 28 has a rim 35 which surrounds wall 23 of cell holder 18 (see FIG. 4) when seated upon it, for preventing the food from spilling out of cell holder 18.
Referring now to FIG. 5B, there is shown cell cover 28 with mixer 36 seated over it. Mixer 36 connects to socket 22 via stem 38, inserted through hole 29 (see FIG. 4). Wings 40 extend from stem 38, and they rotate with handle 12 sliding movement, thereby mixing the dry food in storage receptacle 80 for the purpose of avoiding agglomeration.
Referring now to FIGS. 6A-B, there is shown the dispenser apparatus 200 in use. The components of dispenser apparatus 200 are assembled and storage receptacle 80 is seated over base 10 and filled with dry food 50. Wall 23 has a slot 21 formed therein, for accommodating handle 12 of base 10.
Use of dispenser 100 for dispensing portions of dry food 50, involves a cyclical operation of extraction and release performed in a repeatable fashion.
As shown in FIG. 6A, cell 26a is aligned with opening 31a and is filled with the dry food 50 spilling from storage receptacle 80 above (not shown), while floor 17 (not shown) of base 10 provides a bottom for open-bottomed cell 26a so that the food 50 stays in the cell 26.
When handle 12 is slid from one side to the other in a first direction, hub 11 rotates and cell holder 18 is rotated along with it (see FIGS. 2 and 3A). The rotation of cell holder 18 thereby rotates cassette 24, until cell 26a is aligned with dispensing aperture 15 so that the dry food 50 is released and drops from open-bottomed cell 26a through dispensing aperture 15 and exits dispenser 100.
Thus as a result of the motion of handle 12 shown in FIG. 6A, cell 26b is aligned with opening 31b, as shown in FIG. 6B. At this point cell 26b is aligned with opening 31b and is filled with dry food 50. For dispensing the portion of food 50 in cell 26b, handle 12 is slid back to the other direction. This cyclical dispensing operation is repeated multiple times until storage receptacle 80 is empty, and then it may be refilled.
With every movement of handle 12, mixer 36 is rotated along, so that wings 40 mix the contained dry food 50 for the purpose of avoiding agglomeration.
Referring now to FIGS. 7A-B, there is shown cell cover 128, adapted for use with powdered foods, unlike granular foods. Cell cover 128 has a single level, which is flat surface 130, with hole 29 disposed in the center for accommodating socket 22 of cell holder 18 (not shown here).
A feature for easily and directly attaching cell cover 128 to a commercially sold bottle 90 of powdered food is screw threads 135. Screw threads 135 allow for a manufacturer's bottle 90 of powdered food, such as protein powder, to be directly attached to dispensing apparatus 200, rather than transferring the contents of bottle 90 into storage receptacle 80, thereby avoiding possible spillage and contamination of the powder.
Referring now to FIG. 8, there is shown cell cover 128′, which is similar to cell cover 128 but without screw threads 135, for the attachment of storage receptacle 80.
Referring now to FIGS. 9-10, there is shown mixer 136 which connects to cell cover 128 or 128′, having a hub cover 144 connecting over hub 11, and flat-bottomed wings 140 disposed on two sides of the bottom of hub cover 144 which wipe surface 130, by being situated closely to it. Mixer 136 rotates as handle 12 is slid from side to side, thereby having wings 140 wiping dry food from surface 130 and into cell 26. Support rods 142 of mixer 136 are for the purpose of mixing the powdered food to avoid agglomeration, and for strengthening the support of flat-bottomed wings 140 connected to the hub cover 144. Nut 146 is connected over hub cover 144, for locking all the parts together, so they will not become separated.
Although particular embodiments of the invention have been described and illustrated herein, it is recognized that modifications and variations may readily occur to those skilled in the art and consequently, it is intended that the claims be interpreted to cover such modifications and equivalents.
