DETAILED DESCRIPTION OF THE INVENTION

[0043] Referring now to the drawings and the characters of reference marked thereon, FIGS. 1-8 illustrate a dry agricultural product container 10, in accordance with the principles of this invention, having a trapezoidal configuration that allows dry agricultural product, typically a flowable, granular material, to gravity flow down sides 12, through a discharge port, to a removable attached discharge valve 13. Handle 14 provides a method of carrying the container 10. A recessed panel 18, having a beveled edge, is designed to nest into a matching raised panel 19 on an adjacent container on a container pallet (not shown) thus designed to locate and prevent the containers from shifting in transit. A raised panel 19 (see FIG. 2), having a complementary shape with recessed panel 18 of container 10, is designed to have containers interlock when stacked upon one another. A recessed rectangular platform 20, on a vertical side 22 of container 10, provides a protective area for placement of an RFID tag 24. Weather cap 26, of container 10, provides protection from the elements insuring granular product is free of moisture. The weather cap 26 covers a filling opening.

[0044] This unique shape for a dry agricultural product container provides an efficient trapezoidal flow path. As used herein, when referring to the trapezoidal flow path, the term trapezoidal flow path refers broadly to a flow path that has a larger width adjacent to the product volume and a smaller width at the outlet, regardless of whether the taper between the larger width and smaller width is continuous or discontinuous or interrupted or uninterrupted.

[0045] In the preferred embodiment, illustrated in FIGS. 1-8, the front face 28 and the rear face 30 each have a truncated trapezoidal shape. As used herein the term truncated trapezoidal shape refers to a trapezoid with two truncated apices. In this preferred embodiment the front face 28, the rear face 30, a top base 32, a bottom base 33, a first vertical side 36 adjacent to the top base 32, the second vertical side 22 adjacent to the top base 32, the first sloped side 12 between the first vertical side 36 and the bottom base 33, a second sloped side 34 between the second vertical side 22 and the bottom base 34, are collectively configured to form an enclosure.

[0046] This dry agricultural product container 10 cooperates in a synergistic manner with a liquid agricultural product container, as will be discussed below.

[0047] Referring now to FIGS. 9-16, a liquid agricultural product container, designated generally as 38, is illustrated. The liquid agricultural product container 38 preferably includes two protective caps 40, 42 for shipping and storage. One of the top caps is removable for filling the liquid agricultural product container. The other cap is removable to provide access for appropriate fluid conduits. In this preferred embodiment of a liquid container shown in FIGS. 9-16 the front face 44 and the rear face 46 each have an angled, truncated trapezoidal shape referring to apices that are not only truncated but also angled.

[0048] Referring now to FIGS. 17-29, an overall container system, designated generally as 100 is illustrated. The container system 100, for transporting and dispensing agricultural products, includes a housing assembly 102 and a set of agricultural product containers 10, 10, and 38. The housing assembly 102 is shown secured to a planter 103. The housing assembly 102 includes a number of slot assemblies 104 for the containers 10, 10, and 38. The agricultural product containers are configured to be releasably contained within the slot assemblies 104. In these figures, the set of agricultural product containers includes a liquid agricultural product container 38 and two dry agricultural product containers 10, 10. The slot assemblies 104 and agricultural product containers are cooperatively configured to provide the ability to interchange any of the agricultural product containers within the slot assemblies. In other words, dry agricultural product containers can be placed in any of the slots and liquid agricultural product containers can be placed in any of the slots. In the example shown in these figures three containers are illustrated, two being dry agricultural product containers 10, 10 and one being a liquid agricultural product container 38. However, it is understood that container system 100 can be manufactured to include a desired number of slot assemblies 104.

[0049] The housing assembly 102 includes push assemblies 108, each associated with a respective slot assembly 104. Lock arm assemblies 110 are operably connected to the push assemblies 108, wherein actuation of a push assembly 108 by a user disengages a lock arm assembly 110 from a container providing for the capability to release the container from the slot assembly 104.

[0050] FIGS. 18-22 show two dry containers 10, 10, 38 being removed from the housing assembly 102, with one of the dry containers being replaced. The dry agricultural containers are oriented within the slot assemblies 104 so that the discharge valve 13 is positioned on the bottom.

[0051] FIG. 18 illustrates a first step in the manner in which a dry container 10 is released from the system 100. In a first step the operator rotates a handle element 112 and pushes it in. This causes a hold down (release) arm 114 of the lock arm assembly 110 to rotate up and away from an associated container. (The ability to provide this actuation will be discussed in detail below with respect to FIG. 29.)

[0052] FIG. 19 shows the dry container 10 being removed from the housing assembly 102. (The hold down arm 114 associated with the end dry container 10 also shown lifted in the first step toward its removal.)

[0053] FIG. 20 shows two push assemblies 108 opened, one of the dry containers 10 shown being installed, one of the slot assemblies 104 being empty. Thus, for example, one of the dry containers can be swapped with another dry container.

[0054] FIG. 21 illustrates engagement of the handle element 112 to secure the (middle) dry container 10 in the housing assembly. The associated handle element 112 has been pushed out to hold the middle container 10 in place.

[0055] FIG. 22 shows the containers 10, 10, 38 in place within the housing assembly 102. Orientation of the handle element 112 to a vertical position indicates that the agricultural product is ready to be dispensed.

[0056] Each of the slot assemblies are preferably configured to accommodate either liquid agricultural product containers or dry agricultural product containers. The slot assemblies and agricultural product containers are preferably cooperatively configured to provide the ability to interchange the agricultural product containers within the slot assemblies.

[0057] As shown in FIG. 23, a liquid container 38 is released in a similar manner as the dry container by rotating and actuating the handle element 112. However, the appropriate fluid conduits 120 are required to be connected. The fluid conduit connections are completed using leak-proof, quick-connect/disconnect union devices of a type that are similar in speed and operation to the quick-connect/disconnect union devices commonly found on pressurized air hoses that are used to add air to automobile tires. These conduits 120 connect the liquid container 38 to a liquid pump 122, as will be discussed below.

[0058] FIG. 24 shows a liquid container 38 being removed. It can be swapped with either another liquid container or with a dry container.

[0059] FIG. 25 shows a dry container 10 being removed from the middle slot.

[0060] In FIG. 26 that middle slot is shown being used to support a liquid container 38.

[0061] The slot assembly 104 includes the ability to hold liquid pumps 122 to support the operation of liquid containers 38. FIG. 27 shows a liquid pump 122 being removed from the slot assembly. A variety of different types of liquid pumps may be utilized. A syringe type pump is preferred. Such a syringe-type is disclosed in, for example, U.S. Publication No. US 2018/0359909 (U.S. patent application Ser. No. 16/112,660) incorporated by reference herein, in its entirety. Both the liquid pumps and dry meters may be attached/reattached by quick detach mechanisms.

[0062] Referring to FIG. 28, a dry meter 124 is supported in the housing assembly 102 below the dry container 10. The dry meter 124 may be an electromechanical solenoid driven device for dry material. One type of metering device is described in U.S. Pat. No. 7,171,913, entitled Self-Calibrating Meter With In-Meter Diffuser. Another type of metering device is described in U.S. Pat. No. 5,687,782, entitled Transfer Valve For a Granular Materials Dispensing System. Another type of metering device is described in U.S. Pat. No. 5,524,794, entitled Metering Device for Granular Materials. Another type of metering device for dry granular material is described in U.S. Pat. No. 5,156,372, entitled Metering Device for Granular Materials. Another type of metering device, is described in U.S. Publication No. US20170043961A1, entitled Brush Auger Meter, which describes a device for metering granular or powdered product, having a meter housing, an auger housing positioned within the meter housing, the auger housing having an inlet opening for receiving the granular or powdered product, a rotatable spiral brush mounted within the auger housing, a first discharge outlet near one end of the auger housing for discharging granular or powdered product, and another opening near another end of the auger housing for discharging granular or powdered product not discharged through the first discharge opening. U.S. Pat. Nos. 7,171,913; 5,687,782; 5,524,794; 5,156,372 and, U.S. Publication No. US20170043961A1 are incorporated herein by reference in their entireties. FIG. 28 shows detachment of a dry meter 124 from the housing assembly, via a quick detach mechanism. The left hand has lifted the left latch 126 and the right hand has grasped the right latch 128 but not opened it yet.

[0063] Referring now to FIG. 29 a container system is illustrated with the end walls of the housing assembly 102 removed to show the housing assembly 102 in greater detail than the previous figures. Each push assembly 108 includes a handle assembly 130 engageable by a user via the handle element 112. The handle assembly 130 includes the handle element 112, a handle shaft 132, and handle assembly pins 134.

[0064] Each push assembly 108 also includes a rail assembly 136 operably connected to the handle assembly 130 having a vertical element 138 for pushing against a vertical portion 140 of an associated lock arm assembly 110 enabling rotation thereof for disengagement of a container.

[0065] The rail assembly 136 includes a tab 142 at an end thereof which releases the associated lock arm assembly 110 enabling the rotation thereof. The lock arm assembly 110 includes a slot 144 for detaching the lock arm assembly 110 from the push assembly 108 thus allowing the lock arm assembly 110 to rotate away from the abutting container when the handle assembly 130 is pushed in.

[0066] Each rail assembly 136 includes rail assembly pins 146 for engagement with the discharge valve assembly 13 attachable to a container to control discharge of agricultural products. A sprocket 148 of the discharge valve assembly engages the rail assembly pins 146 to open a discharge valve of the discharge valve assembly 13 when a container has been secured. When the container is detached the push assembly 108 also automatically closes the discharge valve. Thus, in this preferred embodiment each push assembly and operably connectable lock arm assembly collectively define a container lock assembly mechanism which is operably connectable to a discharge valve assembly attachable to a container by this key engagement therebetween.

[0067] The push assembly 108, when engaged to release a container, simultaneously 1) pushes the tab 142 away from the lock arm assembly 110; 2) lifts the hold down arm 114 of the lock arm assembly 110, providing rotation of the lock arm assembly 110; and, 3) closes the discharge valve of the discharge valve assembly 13.

[0068] The handle assembly pins 134 engage a slot 148 on the rail assembly 136 to provide axial movement of the handle shaft beyond a stop point. Complete actuation of the handle assembly 130 requires further rotations of the handle 112 to provide alignment of the handle assembly pins 134 with the slot 148 on the rail assembly 136. This is provided for safety purposes.

[0069] In summary, the agricultural containers include the following features:

[0070] Trapezoid shapeWith the dry containers the sloped sides allow a sufficiently steep angle of repose that allows granules to gravity-flow out the discharge outlet in the bottom of the container. The similarly shaped liquid container can be used in the common container housing assembly on a planter row unit, as discussed above.

[0071] The recessed area in the top of the container serves as a handle that's built-in/integral to the container as the container is being manufactured during, for example, a rotational molding process. The handle facilitates installation and removal of filled containers.

[0072] The opening on one side of the dry container serves as the access point by which agricultural product is introduced into the container during the filling/refilling process. A protective, tamper-evident cap is provided to prevent moisture and/or anything other than the intended and authorized crop input product from an authorized refiller from entering the dry cartridge and to provide evidence if the seal for this area has been broken. If the seal is been broken, the dry cartridge is not generally eligible for refilling unless and until it's been emptied, washed, and re-certified as clean and eligible for use.

[0073] Both dry and liquid cartridges preferably include a raised panel on one face and a recessed panel on the opposite face. This facilitates shipment of the containers, as the raised panel from one container resides within or nests with the recessed area of a container that's stacked adjacent to it. The nesting feature minimizes movement of the containers when stacked.

[0074] The discharge port on the bottom of the dry container is the point from which product flows during application. In one embodiment, a rotating discharge valve may be manufactured separately from the container. The valve can be installed as part of an operational cartridge each and every time. The valve will work in combination with the hardware/software on the operating equipment.

[0075] The discharge port of the liquid container does not have a rotating valve; and, the discharge port of the liquid container is positioned in a different location from the discharge port of a dry container. The different position is to prevent leakage from a liquid container into the dry application meter that resides directly below the discharge port of a dry container; 3) liquid product is sucked out of the container via a dip-tube positioned in the container. The dip tube may be manufactured separately and installed in each liquid container in a manner that is similar to how a rotating valve is installed in each dry container. Each dip tube is preferably equipped with a fitting/apparatus that allows a quick-connect/disconnect device to be attached to another fitting that, when attached, allows the liquid contents of the container to be pumped-out/withdrawn from the container.

[0076] The agricultural products may be nematicides or insecticides, or a wide variety of other crop enhancement agricultural products such as fungicides, plant growth regulators (PGRs), micro-nutrients, etc.

[0077] The container system herein is particularly useful with low rate agricultural products. As used herein the term low rate as it applies to liquids refers to a rate defined as below 3.7 fluid ounces per 1000 row feet. When utilized with a syringe pump ultra-low rates are achievable, i.e. below 0.9 fluid ounces per 1000 row feet. As it applies to dry, flowable agricultural products the term low rate refers to a rate below 3 ounces per 1000 row feet.

[0078] U.S. patent application Ser. No. 16/112,660, filed Aug. 25, 2018, entitled SYSTEM AND METHOD FOR DISPENSING MULTIPLE LOW RATE AGRICULTURAL PRODUCTS, discussed above discloses various systems and methods for applying agricultural products as well as dry meters and liquid pumps for these systems.

[0079] As mentioned above, other embodiments and configurations may be devised without departing from the spirit of the invention and the scope of the appended claims.
