- the present apparatus is useful for storage and dispensing of flour, sugar, baking powder, baking soda, oats, rice, peas, and nuts, just to name a few.
- there are additionally applications outside the kitchen where the precise dispensing of bulk material, preferably by weight, would be desirable.
- an embodiment is contemplated wherein a plurality of ingredients are stored and selectively dispensed.
- This is particularly applicable to spices and flavorings, or other ingredients that are typically used in smaller quantities than flour, sugar, or the like. Accordingly, the size of storage necessary for convenient and usage of such small-quantity ingredients is reduced.
- Plural ingredients may be stored separately in a single unit that is not excessive in size. The user may select the ingredient to be dispensed along with the quantity via keypad 28.

- a precision measurement dispenser is a precision measuring converter and output device for dry goods such as flours and grains or other granular substances.
- One of its primary purposes is to eliminate the need for measuring cups or guesswork between units of measurement.
- the PMD uses the same amount of counter space (e.g., footprint) as a standard canister, may have an added feature of adjustable height to collapse into the same overall space as a conventional canister of similar volume. Is also may extend vertically to accommodate bowls or containers of various sizes.
- An internal scale converts cups to grams, in addition to other conversions.
- a digital display shows introduced and converted amounts; interchangeable canisters can be reserved and stored according to their contents.
- An internal processor may display the contents of each interchangeable canister, aiding in proper dispensing and conversion.
- a vacuum seal on the canister may allow for long-term storage.
- An air-sealed chamber dispenses directly into a bowl or vessel of choice.
- the PMD can be used to measure and store various types of materials such as flours or grains.
- the PMD may be battery, solar or cord-powered.
- An upper part comprises an interchangeable storage/input container which slides vertically and is held in place with a ratcheting mechanism; Hinged feed-door in top; Window gauge or optionally a transparent or translucent canister; LCD readout; Control buttons or touch screen controls for conversion of cups-to-gram, ounces-to- grams, pounds-to-grams, grams-to-ounces, gram-to-pounds, and other calculations including internal calculations executed to convert a requested volumetric quantity of material to a corresponding weight; Processor and scale inside upper housing which surrounds the storage/input container; Cylinder with airlock and feed-screw;
- a bowl or other container is placed on the PMD's output base.
- the PMD may be adjusted to the height of the output container.
- Flour or other dry granular substance is either previously- stored or poured into top of the container. If previously- stored, the container may be separable and attached to the PMD at the time of use.
- the processor may calculate the output and a LCD readout shows the exact amount to be dispensed, in the target measurement, and dispenses the amount into the bowl in the output base.
- the user pours the substance to be measured into the input container (FIG. 4). Using the control buttons or touch screen controls on the container cylinder (FIG. 5), the user enters the desired output amounts (for example, 1 cup).
- the calculator inside the unit's upper part (not pictured- internal) computes the output in the desired measurement and displays that in the LCD readout (FIG. 6).
- the door of the inner airlock chamber (FIG. 7) opens to receive the granular substance and the feed screw (FIG. 8) of a screw feed apparatus turns to fill the cylinder.
- the airlock chamber rotates so that the door faces downward and the first part of the substance is delivered.
- the airlock chamber rotates to receive more of the granular substance (if necessary), and the feed screw continues in the other direction, pushing more of the substance into the cylinder (FIG. 8).
- the airlock chamber rotates again, repeating the process while the feed screw continues moving in alternate directions to quickly fill the airlock chamber.
- the airlock chamber works fluidly with the feed screw to alternately receive and expel the substance until the desired amount is finally deposited. This cycle repeats until desired weight is subtracted from the storage container.
- the feed screw may be capable of measuring out accurate measurements down to the desired precision, such as 0.125 oz.
- the remaining granular substance in the container can then be further meted out, or it can be stored, optionally after re-establishment of a vacuum seal within the storage container.
- An internal switchboard gives the user ability to assign each storage/input container to a particular ingredient.
- the storage/input container slides on and off the unit vertically and can be interchanged with other containers for ease of cleaning and measuring of differing materials.
- the upper part with an interchangeable input container ABS plastic. Hinged feed-door-transparent polycarbonate. Window gauge- transparent polycarbonate. LCD readout— per component supplier/manufacturer; Control buttons- ABS plastic; Processor and scale-per component
- injection molding would be the choice of manufacturing. Injection molding is the most commonly practiced plastic processing method in the plastics industry. This process can produce all different shapes and sizes of plastic products, and can produce the most complex of plastic parts. Injection molding uses force to push plastic into a cold steel mold to form the part being produced.
- Humidity control is contemplated for the present PMD, notwithstanding the implied cost of an associated compressor and refrigeration unit for condensing and removing humidity.
- a heat pipe may be employed, similar to those used in computer-processor cooling, notwithstanding the cost.
- Humidity control may also be achieved by use of desiccants and humectants (such as in a container cover).
- Humidity control may also be achieved by use of desiccants and humectants (such as in a container cover).
- a significant improvement over prior art devices may be realized by incorporating the dispensing section 24 into the storage container 18. Such an embodiment may eliminate cross-contamination since the parts that touch the material will stay with the container at all times. Power for the mechanism may be provided by the storage dispensing unit base through mechanical couplings, electrical connections, or the like.
- embodiments described herein may thus be configured with the dispensing section mechanism integrated or otherwise included into the storage compartment 18.
- FIG. 9A schematically illustrates an embodiment wherein a single base unit interacts with multiple storage compartments 18 that each include a dispensing section mechanism 24.
- a stationary base unit comprises base 12, a scale section or weighing tray 30, and a motor unit 120.
- the vessel or bowl 32 is placed on the weighing tray 30 and the scale zeroed upon determination of the tare (not illustrated).

- the dispensing section mechanism 24 interfaces with a drive unit or motor 120 in order to dispense material under the control of the base unit. While illustrated as having a particular number of uniform sized storage containers 18, any number and configuration of storage containers 18 may be employed.
- FIG. 9B schematically illustrates another embodiment wherein a single base unit interacts with multiple storage compartments 18 that each include a dispensing section mechanism 24.
- a movable base unit comprises base 12, a scale section or weighing tray 30, and a motor unit 120 that are mounted on a translational means such as a rail 91.
- the vessel or bowl 32 is placed on the weighing tray 30 and the scale zeroed upon determination of the tare (not illustrated).
- Multiple storage compartments 18 are positioned in a fixed manner relative to one another and the base unit is moved in order to interact with the various storage compartments 18.
- the movement may be manual or controlled by a processor or controller (not shown) of the base unit so that material can be dispensed from the various storage compartments 18.
- a processor or controller not shown
- the drive unit or motor 120 interfaces with dispensing section mechanism 24 in order to dispense material under the control of the base unit. While illustrated as having a particular number of uniform sized storage containers 18, any number, size, and configuration of storage containers 18 may be employed.
- each of the plurality of storage containers may include an identifier 95 and the base unit may comprise a reader 96 so that it may determine the material stored in the storage container 18.
- Identifiers 95 may be located on the container or a cover of the container.
- Identifiers 95 may include radio frequency identification (RFID) tags, bar codes, QR codes, etc. with reader 96 being an appropriate reading mechanism.
- RFID radio frequency identification
- Other mechanisms such as near field communication (NFC) and
- Bluetooth low energy can also be used to provide identification, as well as quantity or other sensed variables via a built-in sensor (not shown).
- the controller may have the identifiers 95 pre-programmed, or may include a training procedure for input of the identifier 95 along with an association with a particular material. In this manner, recipes can be automatically dispensed from the various storage containers 18 under the control of the base unit.
- FIG. 10 Another embodiment of a dispensing section mechanism 24 included on a storage container 18 is illustrated in FIG. 10.
- the feed screw of FIG. 8 is replaced with a substantially cylindrical roller or shaft 100 of a roller feed mechanism.
- Storage compartment 18 is mounted above shaft 100, allowing the stored granular material to be introduced to the top surface of the shaft 100.
- a motor or other drive unit turns shaft 100 clockwise in the embodiment, which draws the material against metering wall 110 and then ejects the material below based upon gravity.
- Shaft 100 or metering wall 110 may be moved relative to each other or relative to storage compartment 18 to regulate the flow of material. Additionally, shaft 100 may be moved up against the bottom of storage compartment 18 when not in use, sealing storage compartment 18.
- FIG. 11 is a perspective view of the embodiment of FIG. 10.
- a motor 120 (or other drive unit) may be placed in a convenient position to turn shaft 100.
- the motor 120 may be part of the storage compartment 18 or part of the base unit.
- the surface of shaft 100 may be smooth, coated with a soft rubber- like material, or textured to best suit the material being dispensed.
- the surface of shaft 100 may be knurled metal.
- FIG. 12 An alternative embodiment of the dispensing section mechanism 24 is illustrated in FIG. 12.
- Storage compartment 18 is mounted above a chute 200 with an outlet (not illustrated) feeding material to the chute 200.
- Vibrator 220 is attached to chute 200 via flexural elements 210, which transmit or focus the direction of vibratory motion in a desired direction.
- chute 200 is energized into vibratory motion as illustrated by the arrows in FIG. 12.
- the vibratory motion of chute 200 transports and ejects granular material at a precise rate that may be calibrated. It is also possible to vary the flow based on the position of the chute.
- the position or angle of chute 200 may be adjusted relative to storage compartment 18 in order to adjust the flow rate of material.
- the vibratory action may also provide an advantage by agitating and homogenizing the material to reduce blockages or interruptions in flow, such as by breaking clumps or agglomerations.
- FIG. 13 illustrates a cross-section of the vibratory feed apparatus in accordance with the embodiment of FIG. 12.
- a door 230 may be provided which opens when storage compartment 18 is placed upon the dispenser unit or brought into relation with the base unit.
- material can be introduced by gravity into chute 200 and subsequently transported by the described vibratory motion. While a hinged door 230 is illustrated, this is not meant as a limitation and other means of sealing storage compartment 18 are certainly feasible, such as soft plugs or membranes, sliding doors, or other devices known in the art.
- the dispensing section mechanisms 24 described in FIGS. 1-13 are preferably integrated into corresponding storage containers 18 to avoid cross-contamination problems. Moreover, the dispensing section mechanisms 24 described in FIGS. 1-13 should preferably be able to transport significant quantities of material quickly, yet be able to deliver precise amounts of material, typically down to approximately 1 gram (0.125 oz). This may be a conflicting requirement with the precision desired by the dispensing mechanisms described, since they rely upon mechanical transport of material at an assumed or calibrated rate. No means of measuring the material is provided during actual transport, so inconsistency, gaps, or clumps of material may adversely impact delivery accuracy.
- the dispensing section mechanisms of FIGS. 1-13 will retain some material inside the mechanism after dispensing. This material will remain in an un-sealed environment and is subject to spoiling or contamination. Undispensed material can leak or drop out the bottom from the dispensing section when the container is stored. Thus, it is preferable to provide some means to evacuate the mechanism of this excess material.
- a waste compartment (not illustrated) may optionally be provided in the storage dispenser mechanism, where the dispensing section mechanism is run while closed off from storage compartment 18 but open to the waste compartment. Thus excess material may be deposited in the waste compartment. Means, such as vibration or compressed air, may also be provided to increase the efficacy of this cleaning operation. Further, it may also be possible to reverse the dispensing mechanism and feed excess material back into storage container 18.
- a dispensing section mechanism may be provided which minimizes leftover waste material while simplifying sealing of storage container 18 by employing a shuttle feed mechanism that moves or "shuttles" precise amounts of material to a dispensing port.
- This alternate embodiment may effectively address the problem of fast delivery with precise measurement, since an efficient means of measuring the material is provided during transport.
- the shuttle feed relies upon material volume instead of weight, a first volume of material may be selected based upon an estimated weight of the material, the weight calibrated upon the first amount of shuttle-fed material, and subsequent volumes shuttle-fed to obtain the desired weight of material.
- shuttle-fed amounts may be delivered initially based upon volume, with measured weight being used to adjust the final delivery of material.
- a rotary-type shuttle feed apparatus is disclosed herein, embodiments may also employ a linear-type shuttle feed apparatus or other known shuttle feed mechanisms (not shown).
- material dispensing is accomplished via a rotary shuttle feed apparatus using a disk 300 mounted in the bottom of storage compartment 18.
- Disk 300 is rotated via coupler 320 (illustrated as a toothed gear, although not limited thereto), driven by a motor in or associated with the base of the storage dispenser unit.
- coupler 320 illustrated as a toothed gear, although not limited thereto
- Disk 300 and coupler 320 stay with storage container 18.
- Disk 300 contains two pockets 301 and 302. In the preferred embodiment, pockets
- An agitator 310 is attached to disk 300 and rotates with it.
- a dispensing port 185 is provided in the bottom of storage container 18.
- dispensing port 185 In the neutral or storage position of disk 300, dispensing port 185 is blocked by not being in registration with any pockets, effectively sealing storage container 18.
- pockets 301 and 302 are open to the stored granular material, but not open to dispensing port 185.
- a top view of wheel 300 in the neutral position is shown in FIG. 16.
- pocket 302 is significantly larger than pocket 301, so a different amount of material fills each pocket while wheel 300 is in the neutral position. If the controller of the storage dispensing device commands a large amount of material, the motor rotates wheel 300 clockwise (viewed from above in FIG. 14) via coupler 320. Wheel 300 will rotate clockwise until pocket
- FIG. 17 is a top view showing pocket 302 rotated clockwise into alignment with dispensing port 185.
- pocket 302 may be refilled and re-used if necessary. Note that pocket 301 has remained filled during the entire dispense operation with pocket 302, so it too will be ready for a subsequent dispensing operation.
- FIG. 18 is a top view showing pocket 301 rotated counter-clockwise into alignment with dispensing port 185. Again after dispensing, wheel 300 is rotated back to the neutral position and storage container 18 is sealed, ready for further dispensing.
- FIG. 19 shows outer disk 400 with inner disk 500 mounted within. Material agitator 510 is mounted rigidly to inner disk 500. A wall 501 of inner disk 500 comprises one boundary of the dispensing pocket 401 or outer disk 400. Inner disk 500 can rotate relative to outer disk 400, moving wall 501 and effectively varying the size of dispensing pocket 401.
- drive coupling 420 rotates disk 400 just as in the previous embodiment of FIGS. 14-18.
- a second drive coupling 520 is provided to independently rotate inner disk 500 relative to outer disk 400.
- drive couplings 420 and 520 are coaxial, and are driven by separate coaxial stepper motors in or associated with the storage dispensing unit base. Again, other suitable drive configurations can easily be imagined by someone with ordinary skill in the art.
- inner disk 500 has been rotated clockwise relative to outer disk 400 (by turning coupling 520 relative to coupling 420). This has the effect of positioning wall 501 closer to the opposing wall of dispensing pocket 401, reducing the size of dispensing pocket 401. This configuration would be appropriate for precision measurements, such as for final dispensing to an accurate weight.
- inner coupling 520 is rotated counter-clockwise relative to outer coupling 420. This has the effect of moving wall 501 farther away from the opposing wall of dispensing pocket 401, increasing the size of dispensing pocket 401. This configuration would be appropriate for dispensing larger amounts of material at a faster rate.
- the disk assembly 400-500 is placed in the bottom of storage container 18 and acts to seal the container while in the neutral position. As all or virtually all of the material will fall by gravity through the dispensing port, little to no excess material will need to be addressed. A layer of nonstick material on walls of the dispensing port may be employed to prevent any material from remaining in the flow path outside of the sealed storage container 18. Referring to FIGS. 20-22, prior to dispensing material, the storage dispensing device controller will calculate the ideal cavity or "shot" size. Inner disk 500 will be rotated relative to outer disk 400, via coupler 520, in order to adjust the size of dispensing pocket 401.
- Stepper motors may be used, for example, in the base to provide feedback on dispensing pocket size to the controller.
- the disk assembly 400-500 is rotated together towards the dispensing outlet of storage container, as illustrated in FIG. 23 to deliver a precise amount of material defined by the volume of the dispenser pocket 401 to the dispensing port (not shown) at the lower end of the storage container 18.
- the desired amount of material i.e., "shot" size
- the largest amount of material dispensed each time in pocket 401 is limited by the size of the disks and container, the smallest size is only limited by the granular nature of the material dispensed, such that lgram or less accuracy will typically be achievable.

- the memory 52 stores at least one program and database for providing recipe portion controls.
- the memory 52 and the controller/processor 54 may also be used to store expiration dates for materials in storage containers 18 so that user may be provided with notice when stored materials have expired or are nearing expiration.
- the memory 52 and the controller/processor 54 may further be used to control other storage parameters, such as temperature, humidity, and pressure via sensors and control elements (not shown).
- the memory 52 and the controller/processor 54 may also store and execute programs to be used in conjunction with identifiers (e.g., RFID tags) on storage containers to associate the stored material with the correct containers, as well as track material usage and recommend ordering of additional materials.
- identifiers e.g., RFID tags
- the various embodiments include precision measurement dispenser devices.
- the precision measurement dispenser device may include one or more screw feed augers disposed within the dispensing section of the storage container.
- a primary auger may advance large amounts of material towards the dispensing port, and a secondary precision auger may rotate at

- the various embodiments may also include methods, and mobile devices configured to implement the methods, of managing material dispensing by a precision measurement device.
- the methods may include presenting a recipe having one or more instructions on the display of a mobile communications device; transmitting an ingredient identifier and measurement quantity associated with the current instruction from the mobile communication device to the precision measurement dispenser device; receiving, at the precision measurement dispenser device, the ingredient identifier and measurement quantity and looking up a canister identifier associated with the ingredient identifier (i.e., the container in which an ingredient is stored); detecting the canister identifier of the storage container currently engaged with the base unit of the precision measurement dispenser device; comparing the received canister identifier with the detected canister identifier; and if a match exists, dispensing the material within the storage container in the amount specified by the measurement quantity.
- the precision measurement dispenser device may transmit a confirmation to the mobile device and the mobile device may advance the recipe to the next instruction, presenting the next instruction on the display of the mobile communication device.
- the precision measurement dispenser device may transmit an error message to the mobile communications device, and the mobile communication device may present a notice to the mobile communication device user via the display.
- the method may reiterate until all instructions of the recipe are completed and all materials are dispensed in the specified quantities.
- the dispensing section of the storage container precision measurement dispensing device may include one or more augers 620, and agitators 610.
- Each of the one or more augers may be in material communication the dispensing ports of the storage container (i.e., disposed directly above or adjacent to the dispensing port).
- the augers 620 may have a screw shape (e.g. cork screw), helical shape, etc. Material within the storage container may drop down into the auger by force of gravity, and may be pushed forward towards the dispensing port when the auger 620 is active.
- the auger 620 may be housed within a tubular housing 630, or a semi-tubular housing.
- the tubular housing 630 may trap material within the radial area of the auger 620, which may force the trapped material forward toward the dispensing port 185.
- the augers 620 may be operatively connected to the motor and may active in response to electric signals from the controller.
- Various embodiments may include one or more agitators 610 disposed near or within the dispensing of the storage container.
- the agitators 610 may be implemented with various shapes such as screws, helical shapes, rods, etc. Unlike the augers 620, the agitators 610 are not in material communication with the dispensing port 185. When active, agitators 610 may agitate or vibrate material within the storage container, enabling packed material to settle down into the auger 620, where the material may be easily dispensed via dispensing port 185. In this manner, the one or more agitators 610 may reduce the likelihood of material compaction and increase the efficiency of material dispensing. Additionally, the augers may agitate material in a targeted direction such as toward the dispensing port.
- the dispensing section may include a tubular housing 630 enclosing or partially enclosing an auger 620, and may terminate at the dispensing port 185.
- the dispensing section may include an auger 620 positioned at an upward angle with respect to the bottom of the storage container 18. Such configurations may reduce the extraneous dispensation of material from within the storage container 18 (i.e., material that is not actively pushed into the dispensing port 185 by the auger 620 will settle back down the tubular housing 630).
- the terminating end 626 of the auger 620 may be disposed above the dispensing port 185, or may extend only to the end of the tubular housing 630.
- Material forced forward by the auger 620 may fall out of the dispensing port 185, or onto a chute (as discussed above), and may be captured by a vessel 32.
- the auger 620 may be disposed at a downward angle, or may be horizontal with respect to the bottom of the storage container 18.
- a precision measurement dispenser device is shown with multiple augers 620, 625 and an agitator 610.
- the dispensing section of the storage container 18 may include a primary auger 620 and one or more precision augers 625.
- the primary auger 620 may have a larger radius than the precision auger
- the primary auger 620 may activate, pushing large amounts of material toward the dispensing port. As the dispensing nears completion, the primary auger 620 may deactivate and the precision auger 625 may begin rotating.
- the smaller size and radius of the precision auger 625 may result in dispensing of smaller, more accurate amounts of material.
- the precision auger 625 may be housed or semi-housed within a tubular housing 631 of smaller radius than that of the primary auger tubular housing 630, thereby trapping smaller amounts of material than the tubular housing 630 of the primary auger 620.
- the precision auger 625 may be configured such that specific rotation of the precision auger 625 correlates to a volumetric measurement.
- the processor may determine an amount to be dispensed and may instruct the controller to rotate the precision auger 625 a measure of rotation associated with the determined measurement quantity. For example, a 90 degree rotation of the precision auger 625 may correspond to a tablespoon of material being dispensed.
- the formula and algorithms for correlating the auger rotation to specific measurements of material may vary according to the type of material being dispensed.
- the agitator 610, primary auger 620, and precision auger 625 may lie in parallel, as illustrated in FIG. 27.
- the augers 620, 625 and agitator 610 may be staggered, offset, stacked, or otherwise arranged according to the properties of the intended material for dispensing. Any or all of the augers 620, 625 and agitator610 may be angled or horizontal with respect to the bottom of the storage container 18.
- the auger 620 of the precision measurement dispenser device is shown while in motion.
- the auger 620 is shown in an inactive position, retracted within the tubular housing 630.
- an inner screw 640 may couple the auger 620 to a rotating mechanism 642.
- the tubular housing 630 may have one or more openings at opposing ends to permit entry and exit of material within the storage container. While the auger 620 is inactive, gravity may force material downward through one of the openings and between threads of the auger 620. The threading may act as a barrier to prevent material from travelling forward until the auger 620 is activated.
- a uniform lip or cover may be disposed at the far end of the auger 620 to seal the tubular housing 630 and prevent material from exiting through the dispensing port 185.
- a driveshaft may engage and move the rotation mechanism 642, which may in turn the inner screw 640, as shown in FIG. 28B.
- the rotation of the inner screw 640 may engage the auger 620 thereby beginning auger rotation.
- the auger 620 may move forward, moving the auger cover forward and exposing space between auger threading to one or more openings at the end of the tubular housing 630. As shown in FIG.
- material trapped between the threads of the auger and within the tubular housing 630 may be pushed forward by rotation of the auger threads. This material may exit the tubular housing 630 upon exposure to an opening in the housing wall. One or more openings may be positioned above the dispensing port such that material exiting the tubular housing may fall through the dispensing port and into a waiting vessel.
