  • carbonated beverages which are consumed in the home are supplied to the consumer in either cans or bottles.
  • cans are supplied in 0.33 of a litre sizes and bottles in sizes up to two litres.
  • a carbonated beverage is made up of carbonated water to which there is mixed a juice or syrup.
  • a good tasting beverage requires good water, the proper level of carbonation and the proper proportions between the syrup and carbonated water.
  • a dispenser of the present invention contains all of the elements necessary in a carbonated drink dispenser and in accordance with the invention the carbonator should be capable of being removed.
  • a number of alternate carbonators are possible for use with the present invention.
  • the dispenser is a stored alone unit, which will normally be the case, and must be periodically batch refilled with water, a simple carbonator can be used.
  • the container is pressurized, and safety features are provided to prevent danger to the user at the time of refilling the water container.
  • the presnt invention is concerned with facilitating removal of the carbonator; prior art dispensers in general have not been concerned with removable carbonators.
  • U.S. Patent No. 3,368,718 there is disclosed a beverage dispenser which has a carbonator which is of the batch type in that it is periodically filled with water and to enable this to be done the carbonator is connected to a source of carbon dioxide under pressure by means of a quick disconnect coupling.
  • the coupling comprises however a first coupling part at the end of a hose and a second coupling part on the carbonator tank and these parts must be brought together by being held in the respective hands of the person making the connection to couple the tank to the gas under pressure, which can be difficult if as would appear from the said U.S. Patent, the hose is flexible.
  • the present invention aims to simplify the coupling and in coupling of a carbonating tank to and from a source of gas under pressure in a dispenser for carbonated beverages.
  • a beverage dispenser for carbonated beverages comprising a dispenser housing having a recess, a source of beverage concentrate, a source of gas under pressure, a carbonating tank for holding a batch of water to be carbonated and for location in said recess, a dispensing head, means connecting the gas under pressure, the source of beverage concentrate, the carbonator tank and the dispensing head enabling the dispensing of beverages made up of carbonated water and beverage concentrate, said carbonating tank being connected to said source of gas under pressure by a quick disconnect coupling, comprising a first quick disconnect coupling part which is connected to the said source of gas under pressure, and is rigidly mounted on said housing and a second quick disconnect part rigidly carried by said carbonator tank enabling coupling of the first and second quick disconnect coupling parts to couple the gas under pressure with the interior of the carbonating tank characterised in that said first quick disconnect coupling part is in said recess and is rigidly supported by said housing so that by sliding the carbonating tank into said recess under force coupling
  • Preferbaly when the tank has a cover, there are mechanical interlock means for preventing removal of said cover until a means for relieving pressure is operated; and there are means for preventing said cover from being fully removed whereby if said means for relieving pressure fails, gas can escape without having said cover blow off.
  • the dispenser of the present invention is disclosed primarily as a unit for dispensing cabronated beverages and also as an in-home dispensing unit, it is not limited to such functions. Obviously, as will become evident, the dispenser, with appropriate modification, can also be used in restaurants, soda fountains and the like.
  • the present invention will be described in detail in connection with an in-home dispensing unit particularly adapted for carbonated beverages.

  • Carbonator 23 is supplied with carbon dioxide from a tank 25 through a reducing valve 26, a line 27 and a manifold 29.
  • carbonated water is supplied over line 33 to the manifold 29.
  • the manifold 29 supplies this water to dispensing heads in the form of valves 35 and 36.
  • containers 37 filled with a concentrate which is to be mixed with the diluent.
  • the metering valve for concentrate is in the container 37 and is coupled to and cooperates with the dispensing valves 35 and 36.
  • the container 37 with the concentrate includes valving means to meter the amount of concentrate in response to a relative movement of two parts of a container brought about by the dispensing valve 35 or 36.
  • the supply of carbon dioxide over line 27 is also used to pressurize the concentrate in the containers 37 after being coupled through a reducing valve 39.
  • a line 40 coupling carbon dioxide to supply the diluent at a constant pressure.
  • water source 11 is also the carbonator.
  • the embodiment of the dispenser illustrated in perspective view of Figs. 2a and 2b includes a supporting housing or structure 41 which is preferably of molded plastic.
  • Structure 41 includes a base 43 and an upstanding T-shaped portion 45.
  • the T-shaped portion 45 includes a top wall 47 front and rear walls 49 and 51, respectively, and a central divider 53.
  • a cooling unit 55 mounted to the base 43 is a cooling unit 55. Shown in the cooling unit 55 are ventilation openings 57 which communicate with additional ventilation openings 59 formed in the base 43.
  • a diluent tank Disposed atop the cooling unit 55 and in a recess 63A defined by the structure 71 is a diluent tank, e.g., a water supply and carbonator tank 61 to be described in more detail below.
  • the top surface 55A of said cooling unit forms the base surface of recess 63A and also forms a reference surface for the carbonator tank 61 as shown in Figs. 5 and 6 permitting the quick disconnect coupling parts 8A of the tank to register with these of the manifold 77 when coupling the tank 61 to the manifold.

  • Fig. 3 is a plan view of the dispenser of Figs. 2a and 2b with the covers 63 and 83 removed and the T-shaped center section 45 also removed for clarity of presentation.
  • the carbon dioxide bottle 68 is visible along with its quick disconnect clamp 71 and reducing valve 69.
  • the reducing valve is semi-rigidly mounted and coupled by tubing 87 to the manifold 77. Portions of valves 79A and 79B which are molded integrally with the manifold are also shown. Also shown in cross section is the carbonator tank 61. The carbonator tank contains a coupling 89 which permits a quick disconnect with the manifold 77.
  • Reducing valve 69 reduces the carbon dioxide pressure to 0.275 N/m 2 C0 2 at this pressure is fed through a passage 91 in the manifold 77 to the disconnect coupling 89. From that point it flows through tubing 90 to a restrictor 93, and thence to a diffuser 95. Carbonated water is removed from the carbonator tank through a line 97 extending to the bottom of tank 61 and leading to the coupling 89 whence it enters a passage 99 in whe manifold. This passage connects with two smaller passages 101 and 103, which lead to outlets 105 and 107, in the portion of the valves which is integral with the manifold. At each of the outlets an O-ring seal 109 is provided.
  • Carbon dioxide is also fed through a further pressure reducing valve 111 which is built into the manifold, where the pressure is reduced to 0.037 N/m 2 .
  • valve 111 the carbon dioxide flows in a passage 113 to which are connected two passages 115 and 117, which lead to elongated openings 119 and 121 in the portion of the manifold which comprises part of the valve.
  • an O-ring seal 123 of neoprene or the like is inserted.
  • the manifold 77 can be made of various materials, a plastic is preferred. With such plastic the manifold can be molded and any necessary machining carried out to form the various passageways.
  • Fig. 4 shows the manifold 77 and the dispensing valves in more detail.
  • a threaded fitting 125 is provided in the manifold. As illustrated, this communicates with a channel 127 which is connected directly to the passage 91.
  • tubular fittings 133 and 135. Inserted into appropriate bores 129 and 131 on the left side of the manifold 77, are tubular fittings 133 and 135. These are press fitted into their respective bores 129 and 131.
  • Each contains, threaded therein, a check valve, i.e., a Schrader type valve, 137a and 137b respectively.
  • the fittings 133 and 135 which are rigid insert by sliding into the quick disconnect coupling 89 in the carbonator tank 61 and are sealed by O-rings 136.
  • anvil 139 Within a bore 130 in the coupling 89, mating with the fitting 129, is disposed as anvil 139 followed by a check valve 141 which is blown open by carbon dioxide pressure from the lines 91.
  • another Schrader valve 143 In a bore 137 of the coupling 89 which mates with the fitting 135 is inserted another Schrader valve 143. The valve 143 abuts against the valve 137b opening both valves whe the quick disconnect coupling 89 is attached to the manifold.
  • an anvil similar to anvil 138 opens the valve 137b.
  • the coupling 89 also contains, at its inside, threaded bores 144 and 146 for connecting lines 90 and 97 of Fig. 3.
  • the stub connections 104, 118 are for connection to a remote dispensing valve.
  • the coupling of the carbonator to the dispenser is designed with a view toward ease of operation and low cost.
  • the carbonator will now be explained in more detail in connection with Fig. 5 which is an exploded perspective view of the dispenser showing the manner of insertion and removal of the carbonator.
  • the unit is self standing.
  • the carbonator 61 comprises a metal tank 300 preferably of stainless steel or aluminium, having a lid 301 which is removable in order to refill the carbonator 61 with water.
  • the carbonator 61 includes a quick disconnect coupling 89 from which one line 90 leads through a restriction or orifice 93 to a dispersion block 95.
  • Carbonated water is forced out of the unit through a line 97.
  • Fig. 5 Also shown in Fig. 5 is the end of the manifold 77 with the two rigid connecting fittings 133 and 135 projecting therefrom. As explained in detail in connection with Fig. 4, these slide into appropriate bores in the fitting 89. As also explained in connection with Fig. 4, there are valves both in the fitting 89 and the connecting stubs 133 and 135 of the manifold. What this means is that, when the tank 61 is pulled by sliding away from the manifold, the pressure within the dispensing unit, i.e., that pressurizing the container 81 and the carbonated water in the various passages, which is under pressure, and the gas under pressure being fed from the C0 2 tank are not released. Without such valving, carbonated water would be released from the connecting fitting 135 and the 0.275 N/ m 2 carbon dioxide would flow from the fitting 133.
  • a folding handle 303 is provided in order to aid in the quick disconnect of the carbonator tank 61 and also aid in handling it when disconnected, i.e., to permit refilling.
  • a view of the handle 303 is also provided in the cross section of the carbonator shown on Fig. 6.
  • the handle includes a bracket 305 which is attached vertically to the carbonator tank 300. This is essentially a U-shaped bracket which contains a cutout portion 307 in its central portion, i.e., at this portion only the base of the U is present.
  • the handle itself comprises two arm sections, an upper arm section 309 and a lower arm section 311.
  • the two arm sections are hinged together by means of a pin or pivet 313.
  • the upper arm section 309 is also hinged to the upper part of the bracket 305 by means of a pin or rivet 315.
  • the other end of the lower arm 311 contains a pin or rivet 317 which passes through a slot 320 formed in the U-shaped bracket 305 near its bottom and is retained in place by washers 319.
  • Also hinged to the pin 317 is a downwardly extending retaining pin 321. In the position shown in solid lines on Fig. 6, with the handle folded against the tank 300, the pin 321 extends through an appropriate slot 323 in a support plate 330 in the top of the cooling unit 55.
  • connection stubs 133 and 135 This, along with the insertion of the connection stubs 133 and 135, into the fitting 89, retains the tank 61 in place.
  • coupling 89 could be on the bottom or vertically disposed on the side of carbonator 61 and the weight of carbonator 61 used to maintain the connection.
  • the present invention provides a novel design of the mating of the cover with the container which both insures that the cover cannot be removed until the pressure is released, and at the same time insures that the cover will always be adequately sealed, after the carbonator is refilled.
  • the manner in which the cover fits into the container 300 is best illustrated in Figs. 5, 6 and 8.
  • the container 300 at its top 351 (the container is of solid welded construction) has a stepped profile. It has an upper recess 353 of first diameter in which a top flanged section 355 of the cover 301 rests. Following this is a portion 357 of somewhat smaller diameter containing internal threads 358.
  • the cover 301 contains matching external threads 359 which screw into the threads 358.
  • This section is followed by a section 360 of still smaller diameter which contains on its vertical surface 361 an 0-ring seal 363.
  • 0-ring seal 363 seals against cylindrical circumferential portion 365 of the cover. Because of the location of the seal 363, a radial rather than the convention axial type seal takes place.
  • a rotatable handle 371 shown on Figs. 5 and 8 is provided. This handle rotates to operate a relief valve 372, the lower portion of which is visible in Fig. 6.
  • Handle 371 is hinged to a plunger 377 by means of a pin 379.
  • Plunger 377 has, in a recess 381 at its end, a rubber sealing disc 383. This seals against a plastic valve seat member 385 containing a central bore 380 which is screwed into a threaded bore 387 in the lid 301 and sealed against the bottom of lid 301 with an 0-ring seal 387A.
  • a spring 375 biases the plunger 377 against seat member 385.
  • Rotation of handle 371 upward lifts plunger 377 off seat member 385, by means of a larger radius 388 at the handle end, to release the pressure in the carbonator 61.
  • This valve also acts as a safety valve in that if the pressure exceeds an amount determined by biasing spring 375, the plunger 377 will lift off seat member 385.
  • Figs. 9a-d illustrate an alternate embodiment of a closure for the carbonator lid. Shown is a carbonator lid 301a a with a cylindrical opening 501 therein. Inserted within the openiing 501 is an insert 503 having a first cylindrical section 505 press fitted into the opening 501 followed by an outwardly flared section 507 and a terminating cylindrical section 509.
  • the closure, or stopper mechanism, which is utilized to close the opening in the cover 301 a is of a nature similar to devices used as stoppers for vacuum bottles and also as boat plugs. However, as with the previously described cover for the carbonator, it is necessary that such a closure incorporate means to insure that pressure is relieved before the cover or stopper is removed, and it is also desirable that the closure be capable of performing as a pressure relief valve.
  • the arrangement illustrated in Figs. 9a-d accomplishes all of these functions.
  • the member which actually closes the opening comprises a compressible stopper 511 of rubber, for example.
  • the stopper which is of cylindrical shape with a central bore 512, in the uncompressed state (See Fig. 9d), is fitted over a tube 513.
  • tube 513 At its inner end tube 513 is threaded. At the inner end of the stopper is a washer 515 which is held in place by a nut 517 screwed on the threaded end of tube 513. The stopper 511 is compressed between washer 515 and a washer 519 at the outer end of the stopper, also slid over the tube 513.
  • the tube 513 contains a bore 521 in its outer end which terminates in a conical valve seat 523. A smaller bore 525 extends from the valve seat through to the inner end of the tube 513. At the end of the tube projecting through the washer 519, the tube is slotted to provide two diametrically opposed members or ears 527 and 529.
  • Each of the ears 527 and 529 contains a hole 531 through the end thereof.
  • a bolt 533 on the end of which is a nut 535 passes through these holes and through corresponding holes 537 in camming means 539.
  • Camming means 539 comprise a member of essentially U-shaped cross-section with two identical cam surfaces 541 on the legs thereof on the end of which is a U-shaped lever arm 543. The cam surfaces 541 act against the washer 519. In the position shown in Fig. 9a, the distances between the bolt 533 and the circumference of the cam surface 541 is a maximum. This in turn causes the bolt and with it the tube 513 to move outward compressing the compressible stopper 511. In the position shown in Fig.
  • a valve member 545 seated against the valve seat 523 is a valve member 545, on the end of a rod 547.
  • the rod extends, with a spacing, through a threaded plug 549, which is screwed into internal threads in the end of the tube 513 and provides a guide for rod 547.
  • Biasing spring 551 is disposed between the guide 549 and the valve member 545 biasing the valve member against the seat 523.
  • the end of the rod 547 is attached to an oval ring 553.
  • a cam 555 is mounted to bolt 533.
  • Bolt 533 at least in the central part thereof, has a square cross-section so that the cam 555 turns with the bolt and the camming means 539.
  • Ears 527 and 529 are, of course, mounted so that the bolt 533 turns within the ears, e.g., the bolt is round where it passes through ears 527 and 529.
  • the fluid e.g., carbon dioxide
  • the fluid under pressure would flow thorugh the bore 525 past the valve member 545 through the bore 521 escaping between the rod 547 and the opening in the guide member 549.
  • the rod is disposed within the guide member 549 with a small spacing.
  • the nature of cam 555 is such that in the position shown in Fig. 9a, the distance between the axis of the bolt 533 and the cam surface is a minimum. As noted above, in this position there is a slight spacing between the cam surface and the ring 553. At the position shown in Fig. 9c, in which the handle 543 has been rotated through 90°, a second, larger distance, results.
  • cam surface comes into contact with ring 533 raising the ring and with it, the rod 547.
  • the cam surface of cam 541 is still maintaining the compressible stopper in the compressed state.
  • further rotation of the bundle 543 releases the stopper while at the same time maintaining the valve member 545 raised from the seat 523.
  • the cam surface of cam 555 is such that between the position shown in Fig. 9c and 9d it maintains the ring at the same distance from the axis of the bolt 533 holding the valve open.
  • the cover 63 will contain, on its inside, a layer of insulation 325. Cooling is accomplished one of two ways. In the embodiment shown on Figs. 5 and 6, cooling is done utilizing a pan 327 of essentially cylindrical shape and having a lip 329 at its top. The pan is filled with what is commonly known as "Blue Ice", a type of material typically used for cooling in picnic coolers. The pan containing the Blue Ice sealed therein is placed in a home freezer and frozen prior to use. It is then inserted into the dispenser.
  • the support plate 330 having a circular opening 331 therein to receive the pan 327 is provided. The plate 330 is supported in conventional fashion on a rectangular frame which forms part of the cooling unit.
  • the inside of the rectangular frame 331, this frame resting on the base 43 of the dispensing unit contains insulation (Fig. 5) 333.
  • ventillation holes 57 in the rectangular frame Shown on Fig. 5 are ventillation holes 57 in the rectangular frame, and ventillation holes 59 in the base 43. These are not required with this type of cooling unit but are used with the cooling unit to be described in connection with Fig. 7 below.
  • the plate 330 in which the pan 327 is inserted is preferably of a material with poor heat conductivity, such as polypropylene.
  • the dispenser is provided with an electrical cooling unit.
  • this unit is inserted in, or provided in conjunction with, a plate 330, of poor heat conductivity.
  • the plate contains an opening 323 for the insertion of the pin 321 on the handle 303 of the carbonator 61.
  • the unit includes, below a plate 335 of good heat conductivity, a plurality of thermoelectric cooling units 337. The nature of these units is that they are cool on one side and hot on the other side when electricity is passed through them.
  • the thermoelectric units which are essentially of a platelike material, have their cold side abutting against the plate 335. Attached to their warm side are heat sinks 339.
  • a fan 341 is mounted for conducting heat away from the heat sinks. Power is supplied to the fan and to the thermoelectric cooling units 337 by means of the power line 343. Via a suitable circuit as described in European Application No. 80200611.4 (EP-A-0022589) when operating with such a unit, the warm air is expelled through openings 345 below the fan and is exhausted through the openings 57 and 59 shown in Figs. 5 and 2b.
