Various advantages of this invention will become apparent to those skilled in the art from the following detailed description of the preferred embodiment, when read in light of the accompanying drawings.
As shown in
The source container includes a discharge opening generally indicated at 13. This opening 13 optionally can be configured with a threads to receive a removable, threaded cap 18 during shipping and storage of the source container 12.
Positioned within the source container 12 is piston pump 34. The piston pump 34 is configured to withdraw the concentrate 14 from the source container vessel 11 and then dispense the concentrate in a controlled manner through an exit valve 62 in the discharge opening 13, and into the receiving container 20. The piston pump 34 includes a chamber or temporary reservoir 36 for receiving and dispensing concentrate, a plunger or piston shaft 38, and a piston head 52. The temporary reservoir 36 serves to hold fluid concentrate 14 as needed during the process of dispensing the fluid concentrate. The piston shaft 38 can be any suitable length. The piston shaft 38 can be operated by any suitable means, as will be explained below. In one embodiment the piston pump 34 is a syringe pump.
The piston head 52 is connected to the piston shaft 38 and is mounted for axial movement through the temporary reservoir 36. The movement of the piston head 52 through the temporary reservoir 36 can be accomplished in any suitable manner. In the embodiment shown in
As shown in
As shown in
A cap 49 can be placed on the top of the temporary reservoir 36 for seating the hub 42, the shaft 38, and the vent tube 47, and for sealing the temporary reservoir 36.
Positioned at the bottom of the piston pump 34 is a piston mounting cap 50. The piston cap 50 is provided with threads to enable the cap 50 and piston pump 34 to be threaded onto the opening 13 of the source container 12 in a fluid-tight connection after removal of the shipping cap 18. The cap 50 includes a mounting for the piston pump 34 and for the exit valve 62, and also provides a seat or bearing 51 for the shaft 38. The cap further includes a seat 53 for the vent tube 47.
The one-way exit valve 62 can be any valve suitable for controlling the flow of fluid concentrate from the temporary reservoir to the receiving containers. In the illustrated embodiment, a one-way duckbill valve is used. Other valves can be is used. The valve need not be a one-way valve, but a one-way valve gives the advantage avoiding the inspiration of air during the filling of the temporary reservoir 36 when the piston head 52 is drawn up. Although a single valve 62 is shown, one or more valves controlling the flow of fluid concentrate 14 from the temporary reservoir 38 to the receiving containers 20 can be used.
An intake chamber or well 54 is mounted in the cap 50 to provide access or fluid communication from the vessel 11 to the temporary reservoir 36. The flow of fluid concentrate 14 between the vessel 11 and the temporary reservoir 36 is controlled by one or more inlet valves 55. The inlet valve 55 can be an umbrella valve, as shown in
In typical operation, the stepper motor 44 is first operated to drive the piston head 52 to the bottom of the temporary reservoir 36 of the piston pump 34. Then the piston head 52 is moved upward, drawing fluid concentrate 14 through the inlet valve 55 into the temporary reservoir 36. In one embodiment of operation, the receiving container is filled with diluent, such as water, before the addition of a small amount of the fluid concentrate. When a discharge of concentrate is desired, the stepper motor 44 moves the piston head 52 incrementally downward, forcing the desired amount of concentrate to flow downward through the one-way exit valve 62 and into the receiving container 20. Once all of the concentrate 14 in the temporary reservoir 36 is discharged into a multiplicity of receiving containers 20, the stepper motor 44 is operated to raise the piston head 52 again, thereby refiling the temporary reservoir 36 of the piston pump 34 with additional concentrate from the vessel 11.
It is to be understood that after the source container 12 is filled by the supplier of the concentrate material, the source container can be shipped with the pump 34 positioned within the source container, or in the alternative can be shipped with the pump accompanying the source container.
If the pump is shipped outside of the source container, the customer using the dispensing apparatus removes the shipping cap 18 and installs the pump 34 before using the apparatus. Further, the pump can be part of a dispensing apparatus for dispensing fluid concentrate from a plurality of source containers into a receiving container, where the source containers have a uniform opening suitable for receiving a closure, such as the shipping bottle cap 18. The apparatus includes a connection (e.g. threaded connection) that enables the apparatus to connect to the opening of any one of the plurality of source containers. The apparatus includes a pump configured to be positioned into any one of the source containers and configured to withdraw a portion of the fluid concentrate from the source container and to store the portion of fluid concentrate in a temporary reservoir. The apparatus also can be configured to dispense a metered amount of the fluid concentrate from the temporary reservoir to dispense the fluid concentrate into receiving containers.
Although in the embodiment illustrated in
In one embodiment, the system 10 for dispensing concentrate includes a flushing system for minimizing contamination of the apparatus. As shown in
The flushing system can be modified to be used as a venturi system for filling receiving containers. The venturi system would include a pump connected to the source container, the pump having a temporary reservoir, the pump being operable to withdraw a portion of the fluid concentrate from the source container and to store the portion of the fluid concentrate in the temporary reservoir. The pump is operable to dispense a metered amount of the fluid concentrate from the temporary reservoir through the outlet opening and into the conduit 59. The proper amount of fluid concentrate is dispensed into the conduit 59 to result in the desired concentration of liquid in the receiving container.
Although in the embodiment shown in
The piston head 152 is provided with a one-way discharge valve 154 that allows fluid flow only in the upward direction, into the passageway 44. A seal, not shown, seals the piston head 152 against the walls of the temporary reservoir 136. The lower end of the piston pump 134 includes a suction valve or inlet valve 163, which can be a duck bill valve or any other suitable one-way valve. The inlet valve 163 can be connected to the dip tube 164 which is sized to connect the piston pump 34 to the bottom area of the temporary reservoir 136.
In typical operation, the stepper motor 144 is first operated to drive the piston shaft 138 to the bottom of the temporary reservoir 136 of the piston pump 134. Then the piston moved upward, drawing fluid concentrate 114 through the inlet valve 163 into the temporary reservoir 136. When a discharge of concentrate is desired, the stepper motor 144 moves the piston shaft 138 incrementally downward, forcing the desired amount of concentrate to flow upward through the discharge valve 154, through the hollow center passageway 137, and along the distribution tube 122 to the receiving container 120.
It is to be understood that in any of the embodiments, the stepper motor 44 or 144 can be controlled by the controller 15, and the controller can be configured to keep track of the amount of concentrate dispensed, and to prevent unauthorized discharging from, tampering with, or filling of the source container 12 or 112.
