Abstract
Description
- The present invention is directed to a beverage dispenser for mixing and dispensing a beverage consisting of measured quantities of a base liquid and a flavoring constituent and is particularly related to beverage dispensers wherein the flavoring constituent is provided in disposable, individual serving packets, and to snap-action fluid activated beverage dispensers wherein the flow of base liquid and flavoring constituent is controlled by a pilot flow of fluid under pressure.
- It is known to provide a dispensing valve which employs carbonated water or the like as the base of many combination beverages, wherein it is required to activate the flow of carbonated water before the flow of the various flavoring constituents is introduced into a mixing nozzle and dispensed into a container as shown, by way of example, in U.S. Patent No. 3,703,187. As there shown, depression of a push-button advances a seated valve member out of sealing engagement with an aperture which is in communication with a source of carbonated water. The carbonated water, which is introduced into a nozzle, is allowed to proceed through the aperture into a valving chamber from which it is communicated to a second valve, producing enough pressure to force a selected beverage syrup into the nozzle where it is mixed with the carbonated water.
- A snap-action device has also been found to provide a desirable dispensing method because of the resulting accuracy of control of the flow of beverage components into a mixing and dispensing nozzle. However, a major drawback is encountered because known devices are electrically operated as shown, by way of example, in U.S. Patents Nos. 3,163,177; 3,625,402 and 3,667,724. In each of these dispensers an electrically operated solenoid is employed to trigger the flow of beverage components into an outlet or nozzle from which the mixed beverage is dispensed into a suitable container. It is common to actuate these devices by providing a trip lever adjacent the nozzle which is engaged and tripped when the container is placed under the nozzle. The use of electrically operated solenoids requires a power source whenever the snap-action beverage dispensers are employed.
- While the aforementioned pilot-flow system of U.S. Patent No. 3,703,187 eliminates the need for the additional power source, it has the disadvantages overcome by snap-action devices.
- It is also known to provide a beverage dispenser for mixing and dispensing a beverage consisting of measured quantities of a base liquid and a flavoring constituent wherein the base liquid and the flavoring constituent are simultaneously released into a mixing nozzle and dispensed, as disclosed in the foregoing patents. In these devices the flavoring constituent is supplied by an independent tube or flow path from one of a plurality of reservoirs to the mixing nozzle.
- The present invention is directed to a beverage dispensing apparatus and method which combines the advantages of known snap-action dispensers with the advantages of fluid operated dispensers while overcoming the disadvantages inherent in both types of systems.
- In the system disclosed herein, the beverage dispenser includes a plurality of flow control valves, one each associated with independent sources of a base liquid and one or more flavoring constituents which activate flow of the base liquid and the selected flavoring constituent into a mixing and dispensing nozzle when opened and inhibit said flow when closed. A trip lever or the like is associated with the device and when engaged, snaps from an "off" position to an "on" position for instantaneously activating a pilot flow of fluid to the flow valves for opening same. When disengaged, the trip lever returns to the "off" position and instantaneously inhibits the pilot flow, whereby the flow valves are closed and flow of flavoring constituent and base liquid to the nozzle is stopped.
- The present invention permits use of the base liquid as the pilot fluid, and when the pilot flow is inhibited the pilot fluid may be exhausted into the mixing nozzle without fear of contaminating the mixed beverage. Of course, the means and method disclosed herein also permits use of other pilot fluids which may be returned to the pilot source between cycles.
- The present invention also discloses a beverage dispenser wherein the flavoring constituent may be supplied in sealed, individual serving packets which are automatically released in a controlled manner into the mixing nozzle when the pilot flow is activated. This permits variety of selection of flavoring constituents without duplication of equipment, as is often required in many prior art devices. This embodiment may include the pilot-flow snap action control device.
- Therefore, the present invention provides both a self- contained, fluid operated, snap-action beverage dispenser which is devoid of any electrically powered components and/or a beverage dispenser wherein the flavoring constituent is provided in individual packets. When used for carbonated beverages, it is contemplated that this invention may be used in combination with my copending application, Serial No. 578,169, entitled: "Instantaneous Carbonator Method And Apparatus", filed May 14, 1975. Together these systems provide a completely portable system for making carbonated beverages from any available source of tap water.

- The beverage dispenser 10 includes a
housing 12 having amixing nozzle 14 through which a beverage consisting of measured, thoroughly mixed quantities of a liquid base and a flavoring constituent is dispensed into an open-topped container such as theglass 18. An actuating lever 16 depends fromhousing 12 and is engaged bycontainer 18 as it is advanced in'the direction of arrow A into position under themixing nozzle 14. The lever 16 is shown in the fully advanced position in Fig. 3, at which time the beverage dispenser is actuated and the mixed beverage flows fromnozzle 14 into thecontainer 18. - The liquid base is introduced into the beverage dispenser at
inlet 20. The flow of the base frominlet 20 to the mixingnozzle 14 via the fluid passageway ortube 22 is controlled bycontrol valve 24. The flavoring constituent such as a liquid syrup or the like is introduced into the beverage dispenser from a remote source atinlet 26 and flows through atube 28 from theinlet 26 to aflavoring control valve 30 adjacent the mixing nozzle. When thecontrol valves chambers 23 and 29 and throughtubes container 18. - In a typical case, the base liquid is a carbonated water and the flavoring constituent is a soft drink syrup or the like wherein a 5:1 ratio of water to syrup is required to produce the proper mixture. The rate of flow of the base liquid and a constituent into the
mixing nozzle 14 may be controlled by controlling the rate of the flow from the respective sources connected atinlets chambers 23 and 29 andtubes - Initially, the
valves plunger 32 with a cylindrical member 34 which is movable between an advanced position (not shown) closing the flow fromchambers 23 and 29 intotubes opening chambers 23 and 29 totubes compression spring 36 which serves as bias means for normally urging theplunger 32 and member 34 into the advanced, closed position. In the illustrated embodiment, the upper end of eachplunger 32 includes an enlarged flange 38 in abutting relationship with a sealing diaphragm 40 for maintaining a fluid-tight seal between the plunger and thebias spring 36. - The plunger is housed within a
chamber 42 which is in direct communication withcontrol line 44. It will be seen that when fluid under pressure is present incontrol line 44, the biasing force of eachspring 36 is overcome and eachplunger 32 and member 34 are moved upwardly into the retracted position (Fig. 3) for introducing a flow of base liquid and flavoring constituent intolines mixing nozzle 14. Conversely, when the pressure incontrol line 44 is relieved, thebias spring 36 urges eachplunger 32 and member 34 downwardly into the advanced position for stcpping flow throughline - A snap-action
pilot valve assembly 50 defines the control device for controlling the pressure of fluid in thecontrol line 44. The device includes a pair ofdisplaceable piston enclosures enclosure 52 includes an inlet in direct communication with the source of base liquid via line 56 and anoutlet 58 in communication with thecontrol line 44. Plunger 60 includes member 62 which is movable between the retracted position of Fig. 3 and an advanced position (not shown) for alternately introducing or inhibiting the flow of base liquid from the source at 20 to the control line 44., The chamber ofpiston enclosure 54 has an outlet in direct communication withnozzle 14 viaflow line 66 and an inlet 67 in communication withcontrol line 44. The plunger 70 includesmember 72 which is movable between the advanced position of Fig. 3 and a retracted position (not shown) for alternatively inhibiting and introducing flow of the base liquid in the control line to the nozzle viadrain 66. The respective positions of plungers 60 and 70 are controlled by the snap-action switch 74 and the actuating lever 16. The actuating lever is pivotable about pin 76 and has an upper end 78 in communication with the contoured saddle 80 on switch 74.Spring 82 operates as an over-center spring and maintains the switch in either of two positions, depending on the position of lever 16. The plungers 60 and 70 are coupled to the switch 74, wherein alternate plungers are advanced and retracted depending upon the position of the switch. - When lever 16 is in the retracted position shown in Fig. 1, the switch is disposed such that plunger 60 is advanced into the chamber of
piston enclosure 52 for inhibiting the flow of base liquid intocontrol line 44. Conversely, plunger 70 is retracted and thecontrol line 44 is open to drain 66 through line 68 andenclosure 54. This relieves the pressure in the control line, whereby springs 36 operate to closevalves - When the
container 18 is advanced into engagement with lever 16, the lever is advanced to the position of Fig. 3 and switch 74 is tripped, instantaneously opening the chamber ofenclosure 52 and closing the chamber 34 ofenclosure 54. This introduces a flow of base liquid from the source coupled at 20 intocontrol line 44 via line 56 andenclosure 52, thereby increasing the pressure of the fluid in the control line for raising the members 34 ofvalves nozzle 14. When the container is filled with the desired amount of beverage, it is retracted and biasing means such as tension spring 84 moves the actuating lever 16 to the retracted position of Fig. 1, thereby tripping switch 74, and closing the chamber ofenclosure 52 to flow of base liquid while conversely opening the chamber ofenclosure 54 to drain 66 permitting the pressure incontrol line 44 to be relieved. Since the control fluid in the present embodiment is base liquid, it is convenient to communicatedrain line 66 withnozzle 14, whereby any liquid drained fromcontrol line 44 is discharged into thecontainer 18 as the container is retracted from the dispenser. - A second embodiment of the present invention is illustrated in Figs.,6 and 7. Components which operate in the same manner as like components of the embodiment shown in Figs. 1-5 have been identified by the same reference numerals. As shown in Figs. 6 and 7, the source of flavoring constituent comprises a sealed, collapsible packet 90 having a weakened, sealed outlet at
nipple 92. Flow of the flavoring constituent intonozzle 14 is controlled by an elongated plunger 94 having anenlarged 1ower flange 96 which may be advanced into the packet 90 by introducing fluid under pressure intocontrol line 44. This compresses the packet, breaks the seal in thenipple 92 and expels the contents of the packet into mixingnozzle 14. - The dispenser of Figs. 6 and 7 may include the snap-action pilot valve arrangement of Figs. 1-5. It should, however, be understood that this arrangement is optional and that other activating devices may be employed.
- The beverage dispenser 10 has been modified to include a
chamber 98 which accommodates the flavoring packet 90. Anaccess door 100 is provided in the housing of the dispenser and is in communication withchamber 98, whereby individual serving packets are placed in the dispenser for mixing a selected beverage. In the embodiment shown, the access door is slidable along a pair ofvertical ways 102 and is normally urged into the closed position by biasing means such as thecompression spring 104. Thelower flange 96 of plunger 94 is in communication with thepacket chamber 98, Plunger 94 also includes an enlargedupper flange 106 which is in communication with acontrol mechanism 107. The plunger 94 andflange 106 are housed in an elongated cylinder 108. Aconstant compression spring 110 is disposed within cylinder 108 and is in communication with the lower side offlange 106 for normally urging the plunger into the position shown in Fig. 6, whereby theflange 96 is retracted from thepacket chamber 98. A collapsible, fluid-tight bellows 112 engages the upper edge offlange 106 and is in fluid communication with thecontrol line 44. When thecontrol line 44 is under pressure, bellows 112 is expanded and advances plunger 94 andflange 96 intopacket chamber 98, thereby compressing the packet 90 and expelling the contents thereof throughnipple outlet 92 into mixingnozzle 14. When thecontrol line 44 is open to drain,spring 110 acts againstflange 106, thereby collapsing thebellows 112 and expelling the control fluid therefrom intoline 44. - It should, of course, be understood that the
bellows 112 is utilized to maintain complete fluid isolation between cylinder 108 andcontrol line 44, thereby keeping the piston enclosure including cylinder 108 free of contamination. - The individual serving packet 90 permits a wide variety of flavoring constituents to be utilized without increasing the need of additional apparatus to accommodate a plurality of flavoring constituent sources. In addition, the pacl.et permits the change from one flavoring constituent to another in successive operations of the beverage dispenser without any danger of contaminating any portion of the dispenser in advance of the mixing
nozzle 14 with residual flavoring constituent which may have a detrimental effect on subsequent mixed beverages. - An additional feature of the embodiment of Figs. 6 and 7 is provided by incorporating the micro-switch 170 which is in communication with the
tab 172 on thelower flange 96 of plunger 94. Themicro-switch 170 is actuated by plunger 94 whenflange 96 is advanced to its fully extended position, indicating that all the contents of the packet 90 have been expelled intonozzle 14. The micro-switch is coupled in the known manner to the source of base liquid and stops the flow of base liquid intonozzle 14 and ensures that the proper ratio of base liquid to flavoring constituent is introduced into the mixingnozzle 14 for each individual serving, even though the container is not immediately retracted from actuating lever 16. - As illustrated, the embodiment of Figs. 6 and 7 also in- eludes a
pilot valve assembly 50 which may be connected to either the base liquid source as in Figs. 1-5 or in the alternative to be a separate andindependent pilot source 118, without fear of contaminating the mixed beverage with fluid draining from thepilot control line 44. As shown, the drain side of thepiston enclosure 54 is connected to anexhaust line 114 which is independent of the mixingnozzle 14. Also, the source of base liquid which is controlled byvalve 24 may be independent of thesource 118 which is in communication with the input line 56 to thepilot valve 50. This is particularly advantageous when the base liquid is a carbonated water for mixing soft drinks and the like. A standard water supply may be utilized to control the operation ofpilot valve 50, and the standard water supply may be also input to a carbonator such as the instantaneous carbonator shown and described in the inventor's copending application, Serial No. 578,169 entitled: "Instantaneous Carbonator Method and Apparatus", filed May 14, 1975. It should, of course, be understood that the particular pilot valve arrangement of Figs. 1-5 may be utilized with the packet dispenser apparatus of Figs. 6 and 7 without departing from the scope and spirit of the present invention.
