     BACKGROUND OF THE INVENTION 
     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. Many other beneficial results can be obtained by modifying the invention within the scope of the invention. Accordingly other objects in a full understanding of the invention may be had by referring to the summary of the invention, the detailed description describing the preferred embodiment in addition to the scope of the invention defined by the claims taken in conjunction with the accompanying drawings.

     DETAILED DISCUSSION 
       FIG. 1  is an isometric view of a prior art dispenser device  10  for pumping a first liquid  11  and a second liquid  12 . The dispenser device  10  mixes the first liquid  11  and the second liquid  12  to provide a mixed product  13  for discharge from a discharge aperture  14  into a vessel shown as a cup  15 . In this example, the first liquid  11  is a first liquid concentrate  11  and the second liquid  12  is a second liquid diluent  12 . Preferably, the second liquid diluent  12  is potable water. 
     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  16 A- 16 D for storing four separate first liquid concentrates  11 A- 11 D. The dispenser  10  includes four separate pump and mixing devices  20 A- 20 D controlled by four separate switches  22 A- 22 D. The pump and mixing devices  20 A- 20 D pump the four separate first liquid concentrates  11 A- 11 D to mix with the common second liquid diluent  12  to provide four separate mixed products  13 A- 13 D. The four separate mixed products  13 A- 13 D are discharged from four separate discharge apertures  14 A- 14 D.

Upon activation of one of the operator switches  22 A,  22 B,  22 C and  22 D, the electrical control  50  energizes flow control valve  38  and a selected one of the pumping motors switches  22 A,  22 B,  22 C and  22 D for mixing the liquid diluent  12  with a selected one of the concentrates first liquid concentrates  11 A- 11 D from the containers concentrate containers  16 A- 16 D to produce the mixed product  13 . 
     The prior art dispenser device  10  shown in  FIGS. 1-4  is set forth in U.S. Pat. No. 5,114,047 entitled Pump and Mixing Device for Liquids issued to Richard D. Baron et al which is incorporated by reference into the present application as if fully set forth herein. Although the present invention is set forth with reference to the prior art dispenser device  10  shown in U.S. Pat. No. 5,114,047, it should be understood that the present invention may be used with other types, styles and configurations of dispenser devices. 
       FIG. 5  is an isometric view of the terminal orifice processor  80  of the present invention incorporated into the dispenser device  10 A similar to the prior art dispenser device  10  shown in  FIGS. 1-4 . In this example, the dispenser device  10 A is provided with a new or upgraded front door  64 N from the dispenser device  10  shown in  FIG. 1 . A connector  90  secures the terminal orifice processor  80  below the discharging aperture  14  of the pump and mixing device  20 . In this embodiment of the invention, a front door bottom  68 N of the front door  64 N provides a support for the connector  90  of the terminal orifice processor  80 . 
     In this example, four separate terminal orifice processors  80 A- 80 D are located below the discharging apertures  14 A- 14 D of the pump and mixing devices  20 A- 20 D, respectively. Although four separate terminal orifice processors  80 A- 80 D have been shown located below the discharging apertures  14 A- 14 D of the pump and mixing devices  20 A- 20 D, it should be understood that the present invention is incorporated into a single terminal orifice processor  80 . 
       FIG. 6  is a block diagram similar to  FIG. 2  illustrating the improved terminal orifice processor  80 A with the pump and mixing device  20 A of the prior art dispenser device  10 .

The housing  85  is positioned at an angle relative to partial cylindrical support  110 . The housing  85  is positioned with the distal end  132  of the housing  85  being closer to the distal end  112  of the partial cylindrical support  110  than the proximal end  131  of the housing  85  is from the distal end  111  of the partial cylindrical support  110 . The housing  85  is move upwardly such that the key  117  of the support coupling  91  is inserted within the groove  153  of the arcuate overhange  150 . The side stops  115  and  116  of the support coupling  91  engage with the overhang ends  151  and  152  prevent axial movement of the housing  85  relative to the front door  64 N. 
     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  64 N. 
     The housing  85  is removed from the front door  64 N 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  64 N. 
       FIG. 21  is an enlarged view of a portion of  FIG. 7  illustrating the operation of the terminal orifice processor  60  of  FIGS. 7-20 . The housing  85  is secured to the front door  64 N with the housing input  141  of the housing  85  below the discharging aperture  14 A. 
     Upon actuation of the switch  22 A, the second liquid diluent  12  flows into the pump and mixing device  20 A. The pump and mixing device  20 A pumps the first liquid concentrate  11 A from the concentrate container  16 A. The movement of the pump and mixing device  20 A by the motor  40 A pumps and mixes the first liquid concentrate  11 A with the second liquid diluent  12  and discharge the mixed product  13 A from the discharge aperture orifice  14 A. 
     The mixed product  13 A moves by action of gravity into the input orifice  81  of the terminal orifice processor  80 . The mixed product  13 A enters the processing channel  83  between the input orifice  81  and the terminal orifice  82 . The processing channel  83  processes the mixed product  13 A prior to exiting from the terminal orifice  82  as the processed product  17 A. 
     The mixed product  13 A emanating from the discharging aperture  14 A impacts the angled rear wall portion of the rear wall  135  for altering the direction of the mixed product  13 A. The mixed product  13 A flows along the angled rear wall  135  to impact the front wall  134 . The impact of the mixed product  13 A with the angled rear wall  135  and the front wall  134  substantially reduces the velocity of the mixed product  13 A. Furthermore, the impact of the mixed product  13 A with the angled rear wall  135  and the front wall  134  results in substantial turbulence of the mixed product  13 A. The impact and the turbulence imparted to the mixed product  13 A results in the additional mixing and aeration of the mixed product  13 A to provide the processed product  17 A. The processed product  17 A 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  13 A to provide the processed product  17 . 
     The flow of the mixed product  13 A through the processing channel  83  and about the obstruction  160  enhances the characteristic of the mixed product  13 A into a processed product  17 A. The processed product  17 A 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  13 A through the processing channel  83  and about the obstruction  160  provides additional mixing for the mixed product  13 A. Secondly, the flow of the mixed product  13 A through the processing channel  83  and about the obstruction  160  provides aeration for the mixed product  13 A. Thirdly, the reduced velocity of the mixed product  13 A due to the impact of the mixed product  13 A with the angled rear wall  135  and the front wall  134  allows the dispensing device  10 A to operate at a higher pumping rate of the pump and mixing device  20 A. 
       FIG. 22  is a view similar to  FIG. 14  illustrating a second embodiment of the invention. In this embodiment of the invention, a housing insert  100  is incorporated into the housing  85  shown in  FIGS. 13-21 . A housing insert  100  creates a tortuous path  170  within the processing channel  83  between the input orifice  81  and the terminal orifice  82 . 
       FIGS. 23-27  are various views of the insert  100  of  FIG. 23 . The housing insert  100  comprises a transverse wall  171 . The transverse wall  171  includes a partially circular end  171 A for mating with the generally circular end  141 A of the housing input  141  of the housing  85 . An end  171 B of the transverse wall  171  supports a vertical wall  172 . The transverse wall  171  includes outwardly extending plural ribs  173  and  174  located adjacent to the vertical wall  172 . 
     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. 
       FIGS. 28-31  are various views of the housing  85  including the housing insert  100  shown in  FIG. 22 . The housing insert  100  is inserted within the housing  85  with the partially circular end  171 A of the transverse  171  mating with the generally circular end  141 A of the housing input  141  of the housing  85 . The outwardly extending plural ribs  173  and  174  are received within the slots  146  and  147 . The ribs  161 - 163  of the housing  85  cooperate with the first and second foundations  191  and  192 . The rib  163  is received with the groove  193  defined between the first and second foundations  191  and  192 . The ribs  161  and  162  are located on the opposite sides of the first and second foundations  191  and  192  from the groove  193 . The plural ribs  173  and  174  and the first and second foundations  191  and  192  of the housing insert  100  cooperates with the slots  146  and  147  and the ribs  161 - 163  of the housing  85  to secure the housing insert  100  within the housing  85 . 
     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  FIGS. 30 and 31 , the front fingers  181  and  182  and the central finger  186  are positioned about the central obstruction  160 . The rear fingers  184  and  185  are positioned adjacent to the rear wall  135  and are offset from the cylindrical nozzle  144 . The obstruction  160  located centrally in the housing output  142  of the housing  85  cooperates with the plurality of depending fingers  181 - 186  for creating the tortuous path  170  between the input orifice  81  and the terminal orifice  82 . 
       FIGS. 32 and 33  are enlarged views illustrating the operation of the terminal orifice processor  80  of  FIGS. 22-30 . The housing  85  is secured to the front door  64 N with the input orifice  81  of the housing  85  below the discharging aperture  14 A. 
     Upon actuation of the switch  22 A, the second liquid diluent  12  flows into the pump and mixing device  20 A. The pump and mixing device  20 A pumps the first liquid concentrate  11 A from the concentrate container  16 A. The movement of the pump and mixing device  20 A by the motor  40 A pumps and mixes the first liquid concentrate  11 A with the second liquid diluent  12  and discharge the mixed product  13 A from the discharge aperture orifice  14 A. 
     The mixed product  13 A moves by action of gravity into the input orifice  81  of the terminal orifice processor  80 . The mixed product  13 A enters the processing channel  83  between the input orifice  81  and the terminal orifice  82 . The processing channel  83  processes the mixed product  13 A prior to exiting from the terminal orifice  82  as the processed product  17 A. 
     The mixed product  13 A emanating from the discharging aperture  14 A impacts the angled rear wall portion of the rear wall  135  for altering the direction of the mixed product  13 A. The mixed product  13 A 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  13 A. The turbulence imparted to the mixed product  13 A results in the additional mixing and aeration of the mixed product  13 A to provide the processed product  17 A. 
     After the mixed product  13 A passes through the tortuous path  170  defined by the plurality of depending fingers  181 - 186 , the mixed product  13 A impacts the front wall  134 . The mixed product  13 A 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  13 A 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  13 A and results in substantial turbulence, mixing and aeration of the mixed product  13 A to provide the processed product  17 A. The processed product  17 A 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  13 A to provide the processed product  17 A. 
     The flow of the mixed product  13 A through the processing channel  83  and about the obstruction  160  enhances the characteristic of the mixed product  13 A into a processed product  17 A. The processed product  17 A 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  13 A. 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  13 A 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  13 A through the processing channel  83  and about the obstruction  160  provides additional mixing for the mixed product  13 A. Secondly, the flow of the mixed product  13 A through the processing channel  83  and about the obstruction  160  provides aeration for the mixed product  13 A. Thirdly, the reduced velocity of the mixed product  13 A due to the impact of the mixed product  13 A with the angled rear wall  135  and the front wall  134  allows the dispensing device  10 A to operate at a higher pumping rate of the pump and mixing device  20 A. 
     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.
