1. Field of the Invention
The invention relates to liquid dispensing and more particularly to an improved terminal orifice processor for mixing and aerating a first and a second liquid.
2. Description of the Related Art
Various types of liquid dispensing devices have been provided by the prior art for mixing a first liquid and a second liquid. One particular type of liquid dispensing device relates to the mixing of a concentrate with a diluent. In this type of liquid dispensing device, a liquid concentrate is mixed with a larger volume of liquid diluent for producing a final liquid mixture. Liquid dispensing devices for mixing a liquid concentrate with a liquid diluent have found widespread use for a number of applications including the mixing and dispensing a consumable liquids. When a liquid dispensing device was used for dispensing consumable liquid, the liquid dispensing device must be constructed in a manner to be periodically cleaned in order to maintain the wholesomeness of the consumable liquid.
One significant advancement in the dispensing of consumable liquids from a concentrate is the invention set forth in our U.S. Pat. No. 5,114,047. U.S. Pat. No. 5,114,047 discloses a pump and mixing device for pumping a liquid from a container and mixing with a diluent. The pump and mixing device comprises a body member having an input body portion and an output body portion with a flexible wall defining a pumping chamber between the input body portion and the output body portion. The input body portion has an input aperture for enabling the liquid to flow from the container into the input body portion. The output body portion has an output aperture communicating with the flowing diluent. An input one-way valve is disposed in the input aperture for permitting the flow of liquid only from the container to the pumping chamber whereas an output one-way valve is disposed in the output aperture for permitting the flow of liquid only from the pumping chamber. A motive device reciprocates the output body portion relative to the input body portion between a first and a second position for causing liquid to flow from the container through the input one-way valve into the pumping chamber when the output body portion is moved into the first position and for causing liquid to flow from the pumping chamber through the output one-way valve to mix with the diluent when the output body portion is moved into the second position.
U.S. Pat. No. 5,114,047 was reduced to practice in a beverage vending machine for pumping a liquid concentrate from a container and mixing the concentrate with a diluent. The beverage vending machine mixed various liquid concentrates with water diluent to provide a consumable liquid. The aforesaid beverage vending machine had the advantage of utilizing a disposable pump and mixing device connected to a container storing the liquid concentrate. After the depletion of the liquid concentrate, the pump and mixing device as well as the container was discarded thus eliminating the need for periodic cleaning. The beverage vending machine manufactured under U.S. Pat. No. 5,114,047 found rapid substantial commercial success.
Although the beverage vending machine manufactured under U.S. Pat. No. 5,114,047 remains a successful commercial product to the present day, the beverage vending machine required an improvement in three areas. Firstly, some products were not entirely mixed by the pump and mixing device upon discharge at the terminal orifice of the beverage vending machine. In general this was not a significant problem since the concentrate and the diluent was further mixed upon falling into a drinking container. Secondly, the pump and mixing device did not adequately aerate the mixture of the concentrate and the diluent. Thirdly, the pumping speed of the pump and mixing device was slow compared to some conventional beverage vending machines.
Therefore is an object of this invention is to provide a terminal orifice processor for processing a first and a second liquid emanating from a discharging aperture that improves upon our prior inventions.
Another object of this invention is to provide a terminal orifice processor for processing a first and a second liquid that mixes the first and second liquids.
Another object of this invention is to provide a terminal orifice processor for processing a first and a second liquid to aerate the first and second liquids.
Another object of this invention is to provide a terminal orifice processor for processing a first and a second liquid that enables first and second liquids to be pumped at a higher speed.
Another object of this invention is to provide a terminal orifice processor for processing a first and a second liquid to be retrofitted into existing beverage vending machines.
Another object of this invention is to provide a terminal orifice processor for processing a first and a second liquid that is inexpensive to add to beverage vending machines.
The foregoing has outlined some of the more pertinent objects of the present invention. These objects should be construed as being merely illustrative of some of the more prominent features and applications of the invention.

It should be appreciated by those skilled in the art that the conception and the specific embodiments disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims.
For a fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description taken in connection with the accompanying drawings in which:
Similar reference characters refer to similar parts throughout the several Figures of the drawings.
The dispenser device 10 includes a pump and mixing device 20 controlled by an operator switch 22. Upon actuation of the operator switch 22, the pump and mixing device 20 pumps the first liquid concentrate 11 to mix with the second liquid diluent 12. The mixed first liquid concentrate 11 and the second liquid diluent 12 are discharged as the mixed product 13 from the discharge aperture 14 of the pump and mixing device 20.
In this specific example, the prior art dispenser device 10 includes four concentrate containers 16A-16D for storing four separate first liquid concentrates 11A-11D. The dispenser 10 includes four separate pump and mixing devices 20A-20D controlled by four separate switches 22A-22D. The pump and mixing devices 20A-20D pump the four separate first liquid concentrates 11A-11D to mix with the common second liquid diluent 12 to provide four separate mixed products 13A-13D. The four separate mixed products 13A-13D are discharged from four separate discharge apertures 14A-14D.
An electrical control 50 is connected to operate the control valve 36 and the motor 40A. Upon actuation of the switch 22A, the second liquid diluent 12 flows through the water valve 36 and conduit 38 into the pump and mixing device 20A. Simultaneously, the pump and mixing device 20A pumps the first liquid concentrate 11A from the concentrate container 16A. The movement of the pump and mixing device 20A by the motor 40A pumps and mixes the first liquid concentrate 11A with the second liquid diluent 12 to discharge the mixed product 13A from the discharge aperture 14A.
The second liquid diluent 12 shown as water enters under conventional water pressure through an input conduit 31. The input conduit 31 is connected through a liquid pressure regulator 32 and a conduit 33 to a reservoir 34. A circulating pump 35 circulates the second liquid diluent 12 between the reservoir 34 and a refrigerated compartment 70 for maintaining the second liquid diluent 12 at a proper temperature for use. The control valve 36 controls the flow of the second liquid diluent 12 from the reservoir 34 to pumping and mixing devices 20A-20D through the flexible conduit 38.
A refrigeration unit 72 maintains the refrigerated compartment 70 at a reduced temperature. The refrigeration unit 72 includes a motor 74, a compressor 76 and a fan 78 connected in a conventional arrangement.
The pump and mixing devices 20A-20D are connected to the concentrate containers 16A-16D. The concentrate containers 16A-16D and the attached pump and mixing devices 20A-20D are loaded into and removed from the refrigerated compartment 70 through the front door 64. The refrigerated compartment 70 maintains the first liquid concentrates 11A-11D at a proper temperature for storage and use.
The pumping motors 40A-40D include eccentrics 42 for reciprocating driving arms 44. The reciprocating driving arms 44 are connected through coupling devices 46 to operate the pump and mixing devices 20A-20D.
When the concentrate containers 16A-16D and the attached pump and mixing devices 20A-20D are inserted within the refrigerated compartment 70 the attached pump and mixing devices 20A-20D are connected simultaneously to the conduit 38 and to the coupling devices 46.
The electrical control 50 operates the dispenser device 10 in response to the operator switches 22A, 22B, 22C and 22D. Upon activation of one of the operator switches 22A, 22B, 22C and 22D, the electrical control 50 energizes flow control valve 38 and a selected one of the pumping motors switches 22A, 22B, 22C and 22D for mixing the liquid diluent 12 with a selected one of the concentrates first liquid concentrates 11A-11D from the containers concentrate containers 16A-16D to produce the mixed product 13.
The prior art dispenser device 10 shown in
In this example, four separate terminal orifice processors 80A-80D are located below the discharging apertures 14A-14D of the pump and mixing devices 20A-20D, respectively. Although four separate terminal orifice processors 80A-80D have been shown located below the discharging apertures 14A-14D of the pump and mixing devices 20A-20D, it should be understood that the present invention is incorporated into a single terminal orifice processor 80.
The pump and mixing device 20A operates in the same manner as set forth with reference to
The mixed product 13A moves by action of gravity into the input orifice 81 of the terminal orifice processor 80. The flow of the mixed product 13A through the processing channel 83 enhances the characteristic of the mixed product 13A into a processed product 17A. The processed product 17A is discharged from the terminal orifice 82 of the terminal orifice processor 80 into the cup 15 with enhanced discharge characteristics.
In this specific example, the front door 64N is an upgrade replacement for the prior art dispensing device 10 shown in
The distal end 112 of the partial cylindrical support 110 includes a central recess 114 defining side stops 115 and 116 on opposed sides of the central recess 113. The central recess 114 provides a region of reduced thickness of the partial cylindrical support 110 defining a key 117.
The support coupling 91 includes the side flanges 121 and 122 located on opposed sides of the partial cylindrical support 110. A central wall 123 extends partially into the partial cylindrical receiver 113. A boss 125 having a threaded aperture 126 extends from the front door 64N.
The connector plate 93 is affixed to the front door 64N by a screw 95 threading into the threaded aperture 126 of the boss 125. The connector plate 93 engages with the central wall 123.
The housing 85 defines a housing input 141 and a housing output 142 located at the proximal and distal ends 131 and 132 of the housing 85. The housing input 141 is elongated having generally circular ends 141A and 141B. The housing output 142 is a generally circular forming a substantially cylindrical nozzle 144. The elongated housing input 141 is larger than the generally circular housing output 142 enabling the input orifice 81 to be offset from the terminal orifice 82.
The housing coupling 92 comprises an arcuate overhang 150 extending between overhang ends 151 and 152. A receiver groove 153 is located within the arcuate overhang 150. The receiver groove 153 is adapted to receive the key 117 located at the distal end 112 of the partial cylindrical support 110.
The housing coupling 92 further comprises resilient tabs 155 and 156 extending from the proximal end 131 of the housing 85. The resilient tabs 155 and 156 include lugs 157 and 158 for engaging with the side flanges 121 and 122 located on opposed sides of the partial cylindrical support 110.
In this example, the cylindrical nozzle 144 of the housing output 142 includes a central obstruction 160. A first, second and third ribs 161-163 are located about the peripheral of the circular housing output 142. A support 165 positions the central obstruction 160 within the center of the circular housing output 142.
Referring back to
As the key 117 is inserted within the groove 153, the proximal end 131 of the housing 85 is rotated about the key 117. As the housing 85 is rotated about the key 117, the partially cylindrical receiver 113 compresses resilient tabs 155 and 156 inwardly within the partial cylindrical receiver 113. When the housing 85 is rotated about the key 117 into parallel orientation relative to the partially cylindrical receiver 113, the resilient tabs 155 and 156 expand outwardly enabling the lugs 157 and 158 to engage with the side flanges 121 and 122 of the support coupling 91 to secure the housing 85 to the front door 64N.
The housing 85 is removed from the front door 64N in the following manner. The resilient tabs 155 and 156 are compressed by an operator for disengaging the lugs 157 and 158 from the side flanges 121 and 122 of the support coupling 91. The housing 85 is rotated about the key 117 to remove the resilient tabs 155 and 156 from the partially cylindrical receiver 113. Thereafter, the housing 85 is moved downwardly to remove the key 117 of the support coupling 91 from the groove 153 of the arcuate overhang 150. The housing 85 may be totally removed from the front door 64N.
Upon actuation of the switch 22A, the second liquid diluent 12 flows into the pump and mixing device 20A. The pump and mixing device 20A pumps the first liquid concentrate 11A from the concentrate container 16A. The movement of the pump and mixing device 20A by the motor 40A pumps and mixes the first liquid concentrate 11A with the second liquid diluent 12 and discharge the mixed product 13A from the discharge aperture orifice 14A.
The mixed product 13A moves by action of gravity into the input orifice 81 of the terminal orifice processor 80. The mixed product 13A enters the processing channel 83 between the input orifice 81 and the terminal orifice 82. The processing channel 83 processes the mixed product 13A prior to exiting from the terminal orifice 82 as the processed product 17A.
The mixed product 13A emanating from the discharging aperture 14A impacts the angled rear wall portion of the rear wall 135 for altering the direction of the mixed product 13A. The mixed product 13A flows along the angled rear wall 135 to impact the front wall 134. The impact of the mixed product 13A with the angled rear wall 135 and the front wall 134 substantially reduces the velocity of the mixed product 13A. Furthermore, the impact of the mixed product 13A with the angled rear wall 135 and the front wall 134 results in substantial turbulence of the mixed product 13A. The impact and the turbulence imparted to the mixed product 13A results in the additional mixing and aeration of the mixed product 13A to provide the processed product 17A. The processed product 17A exits from the terminal orifice 82.
The obstruction 160 is located in the housing output 142 of the housing 85 for forming the terminal orifice 82. The obstruction 160 provides additional mixing and aeration of the mixed product 13A to provide the processed product 17.
The flow of the mixed product 13A through the processing channel 83 and about the obstruction 160 enhances the characteristic of the mixed product 13A into a processed product 17A. The processed product 17A is discharged from the terminal orifice 82 of the terminal orifice processor 80 into the cup 15 with enhanced discharge characteristics.
Firstly, the flow of the mixed product 13A through the processing channel 83 and about the obstruction 160 provides additional mixing for the mixed product 13A. Secondly, the flow of the mixed product 13A through the processing channel 83 and about the obstruction 160 provides aeration for the mixed product 13A. Thirdly, the reduced velocity of the mixed product 13A due to the impact of the mixed product 13A with the angled rear wall 135 and the front wall 134 allows the dispensing device 10A to operate at a higher pumping rate of the pump and mixing device 20A.
The housing insert 110 comprises a plurality of depending fingers 181-186 extending from an underside of the transverse 171. The plurality of depending fingers 181-186 include front fingers 181 and 182, rear fingers 184 and 185 and a central finger 186. The front fingers 181 and 182 are longer than the central finger 186. Similarly, the central finger 186 is longer than the rear fingers 184 and 185.
The housing insert 110 includes a first and a second foundation 191 and 192 formed on the underside of the transverse 171. A groove 193 is defined between the first and second foundations 191 and 192. Preferably, the housing insert 110 including the plurality of depending fingers 181-186 are formed from a one piece, generally flexible polymeric material.
The transverse wall 171 is offset axially from a center of the cylindrical nozzle 144 of the housing output 141. The transverse wall 171 defines the input orifice 81 that is offset axially from the terminal orifice 82.
As best shown in
Upon actuation of the switch 22A, the second liquid diluent 12 flows into the pump and mixing device 20A. The pump and mixing device 20A pumps the first liquid concentrate 11A from the concentrate container 16A. The movement of the pump and mixing device 20A by the motor 40A pumps and mixes the first liquid concentrate 11A with the second liquid diluent 12 and discharge the mixed product 13A from the discharge aperture orifice 14A.
The mixed product 13A moves by action of gravity into the input orifice 81 of the terminal orifice processor 80. The mixed product 13A enters the processing channel 83 between the input orifice 81 and the terminal orifice 82. The processing channel 83 processes the mixed product 13A prior to exiting from the terminal orifice 82 as the processed product 17A.
The mixed product 13A emanating from the discharging aperture 14A impacts the angled rear wall portion of the rear wall 135 for altering the direction of the mixed product 13A. The mixed product 13A flows through the tortuous path 170 defined by the plurality of depending fingers 181-186 to pass through the tortuous path 170. The tortuous path 170 defined by the plurality of depending fingers 181-186 results in substantial turbulence of the mixed product 13A. The turbulence imparted to the mixed product 13A results in the additional mixing and aeration of the mixed product 13A to provide the processed product 17A.
After the mixed product 13A passes through the tortuous path 170 defined by the plurality of depending fingers 181-186, the mixed product 13A impacts the front wall 134. The mixed product 13A reflects off of the front wall 134 to reenter the tortuous path 170 between the plurality of depending fingers 181-186 and/or a second tortuous path 195 defined between the front fingers 181 and 182, the central finger 186 and the central obstruction 160.
The impact of the mixed product 13A with the angled rear wall 135, the tortuous path 170 between the plurality of depending fingers 181-186, the front wall 134 and the second tortuous path 195 substantially reduces the velocity of the mixed product 13A and results in substantial turbulence, mixing and aeration of the mixed product 13A to provide the processed product 17A. The processed product 17A exits from the terminal orifice 82.
The obstruction 160 and the cooperating front fingers 181 and 182 and central finger 186 forms the terminal orifice 82. The obstruction 160 and the cooperating front fingers 181 and 182 and central finger 186 provide additional mixing and aeration of the mixed product 13A to provide the processed product 17A.
The flow of the mixed product 13A through the processing channel 83 and about the obstruction 160 enhances the characteristic of the mixed product 13A into a processed product 17A. The processed product 17A is discharged from the terminal orifice 82 of the terminal orifice processor 80 into the cup 15 with enhanced discharge characteristics.
The housing insert 110 including the plurality of depending fingers 181-186 are formed from a generally flexible polymeric material. The flexibility of the plurality of depending fingers 181-186 reduces the possibility of buildup of semi-solid matter contained in the mixed product 13A. For example, if the first liquid concentrate 11 is a juice product, the juice product may contain a semi-solid pulp matter.
The flow of the mixed product 13A impacting the plurality of depending fingers 181-186 causes the plurality of depending fingers 181-186 to move or to vibrate. The flexible movement of the flexible depending fingers 181-186 reduces the buildup of the semi-solid pulp matter. In addition, the housing insert 110 may be readily removed from the housing 85 for cleaning and the like.
The terminal orifice processor of the present invention provides a system which substantially advances the liquid dispensing art. Firstly, the flow of the mixed product 13A through the processing channel 83 and about the obstruction 160 provides additional mixing for the mixed product 13A. Secondly, the flow of the mixed product 13A through the processing channel 83 and about the obstruction 160 provides aeration for the mixed product 13A. Thirdly, the reduced velocity of the mixed product 13A due to the impact of the mixed product 13A with the angled rear wall 135 and the front wall 134 allows the dispensing device 10A to operate at a higher pumping rate of the pump and mixing device 20A.
The present disclosure includes that contained in the appended claims as well as that of the foregoing description. Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
