Definitions

  • ABSTRACT A tapping installation suitable for use in the [31] l household for dispensing carbonated beverages comprising an 1967, Germany, B73 499 arrangement for broaching and tapping a container in which the beverage is disposed.
  • the arrangement comprises a builtin valve having a valve body in which a ressure-reducin [54] DEVICE FOR DISPENSING CARBONATED valve is disposed.
  • Means are mounted in the i/alve body whicfi BEVERAGES are adapted to receive a carbonic acid gas capsule which is ar- 21 clalmss D'awmg ranged in front of the valve.

  • Beer is generally tapped from a barrel or other container by breaching it.
  • the carbonic acid gas is introduced into the beer barrel from a steel container through a pressure'reducing valve and the beer is led to a tapping cock through an immersed tube and a beer line and is taken therefrom.
  • a predetermined pressure must exist above the level of the liquid. It is no not difficult to do this in a large beer-tapping installation.
  • the pressure-reducing valve can be constructed sufficiently large in order to function faultlessly.
  • the size of the valve is determined by the closure spring necessary for closing the valve, and by the size of the valve membrane. in large pressure-reducing valves, very high forces, which amount to several kilograms are necessary for sealing the valve seats which consist of plastic materials resistant to carbonic acid gas. This requires a large membrane which again can only be accommodated in a large valve.
  • one of the most common forms of tapping is accomplished as follows: in a bore present in the barrel closure member, a screw part having a rubber seal is inserted and by tightening a wingnut the rubber seal is radially spread and the barrel part is thus sealed.
  • the immersion tube is sealed in a stuffing box provided in an upper part of this arrangement. This immersion pipe is passed through the stuffing box until it is seated on the closure member or bung provided in the screw closure of the barrel. By blows on the immersion pipe, the bung is pressed into the barrel and the pipe is then inserted as far as the bottom of the barrel.
  • the known domestic syphons which are used in the household among other things also for dispensing beer are generally filled at a commercial establishment with a draught supply cock or are filled domestically by emptying bottles of beer into the syphon vessel.
  • domestic syphons do not really supply genuine draught beer because the beer has to be refilled in the aforedescribed manner, which changes the delicate nature of the beer by permitting the escape of carbonic acid gas due to the fact that the beer comes into contact with the ambient air.
  • the invention consists in a device for dispensing carbonated beverages, more particularly beer, comprising an assemblyfor broaching and tapping a container in which the beverage is disposed;
  • Means are provided for supplying carbonic acid gas to the pressure-reducing'valve.
  • the gas sup plying means comprises means for receiving a carbonic acid gas capsule disposed in front of the valve, a pressure-setting device being allocated to the valves.
  • the assembly also comprises a tapping cock and an immersion pipe for insertion into the container, a throttle insert being arranged'in the immersion pipe, the immersion pipe being adapted to cooperate with a packing ring seal provided in a closure of the container when the immersion pipe is inserted into the container through the said seal
  • a tapping cock and an immersion pipe for insertion into the container
  • a throttle insert being arranged'in the immersion pipe
  • the immersion pipe being adapted to cooperate with a packing ring seal provided in a closure of the container when the immersion pipe is inserted into the container through the said seal
  • the new closure of the beverage container allows a simple broaching of the barrel by introducing the immersion pipe, without use of further tools of auxiliary means.
  • the device does not have to be tightened by means of a nut and the danger does not exist that liquid can leak out of the beverage container during the broaching.
  • the throttle means which are disposed in the immersion pipe make it possible to tap the beer while it is in the barrel under a relatively high pressure, without the beer completely frothing when it emerges from the tapping cock.
  • the beer must be kept under its saturation pressure, in order that no carbonic acid gas associated with albuminous material can escape. This pressure amounts for example at 8 C. to 0.75 atmosphere excessp rgssure. If under these conditions the beer has to pass thro ugh only a short path during tapping, it flows out with great turbulence even when the cock is only slightly opened and the carbonic acid gas causes foaming.
  • tapping can be effected only at considerably below the theoretically necessary pressure, which results in the escape of the carbonic acid gas associated with the albuminous material and the suspended bodies, whereby the quality and thus the taste of the beer is impaired.
  • This disadvantage is eliminated by the device ac-" cording to the invention.

  • FIG. 1 DETAILED DESCRIPTION Referring now tothedra'wing there-is illustrated in FIG. 1 the entire device, applied to a vessel or barrel F which is' inserted in a container K having an insulating jacket and a positioning collar.
  • the barrel F and container K may have any suitable shape.
  • the latter container mayadvantageously have cooling means in order to keep the beverage sufficiently cold.
  • the immersion pipe I which extends through the barrel closure 4. which is described below in "detail. is introduced into the barrel F. This part of the device is illustrated insection. I I
  • the section of the immersion pipe I extending upwardly from the barrel F (and through any cladding provided on the barrel). has a sleeve portion which has a laterally extending projection for receiving the valve body 8. the adjusting knob'9 and the container 10 for the carbon dioxide capsule I3.
  • the tapping assembly is given a pleasingappearance by an ornamental delivery pipe Il through which the pipe 1 passes.
  • a tapping cock 12 having an outlet pipe is connected to the upper end of the immersion pipe I.
  • the essential components namely the tapping cock. immersion pipe and pressure-reducing valve are combined to form a single unit and thus a relatively small device is provided with which the tapping of barrel beer is exceptionally simplified andcan be performed by everyone without special skilled knowledge or particular preparations. This is achieved with the construction of the individual elements. and their relationship to one another.
  • An essential requirement for faultlessly tapping beer is a predetermined carbon dioxide pressure, under which the beer should stand during the tapping procedure.
  • This carbon dioxide pressure is dependent on the beer temperature and is also tcrior of the capsule 13 via the bore b with the high-pressure space H of the'pressure-reducing valve (see Fig. 3).
  • a purification filter 16 for the carbon dioxide is provided behind the rearward end of the broaching tip '15.
  • the end of the neck of the capsule I3 is penetrated in a known manner by the cutting I edge of the broaching tip. so that the carbon dioxide can escape from the capsule 13 via the bore in the broaching tip [3.
  • the capsule container 10 with the capsule 13 is, of course. screwed into the valve body 8 only after the barrel F has been broached.
  • the valve body 8 is formed as a lateral projection of the sleeve surrounding the immersion pipe I. It contains an automatically controlling single stage pressure-reducing valve. a nonreturn valve I8 and an excess pressure valve l9.
  • the pressure of the carbon dioxide is reduced to the tapping pressure by means of the pressure-reducing valve.
  • a pressure-reducing valve which operates without a closure spring. and which can be constructed essentially smaller than known valves of this kind.
  • the dimensions of the valve membrane and of the setting spring are considerably reduced when compared with such valves of conventional construction. and thus the external dimensions of the valve can be kept small and pleasing.
  • the valve is provided in the gas inlet part with a sieve-felt filter 16 which holds back impurities such as rust,scale and the like. and behind which the high-pressure part of the valve is disposed.
  • a sealing screw 17 (see FIG. 2) separates the low- I disposed within the bore 30.
  • a hollow pull rod 28 is threadably mounted in the shank 29 which extends through the O-ring seal 27 and through the externally profiled bush 26.
  • the latter serves as a seat for the Owing '27.
  • One end of this pull rod 28 is fixed to the membrane mount 24.
  • the O-ring 27 is fixed to the membrane mount 24.
  • the pressure is selectable within a range of about 0.4 to H atmospheres excess pressure. whereby the tapping procedure and thus the appearance of the beer can be suited to the personal wishes of the consumer.
  • the carbon dioxide amount necessary to obtain this result is contained in a C0 capsule 13. preferably a l6 g. capsule. This capsule is inserted in the capsule container 10 provided therefor. and is screwed with the latter into the tapping device.
  • the free end of the valve body 8 has an open threaded bore into which the capsule container 10 is threaded.
  • the receiving space for the capsule container 10 is closed in the direction of the valve by a seal 14 through which a broaching tip 15 extends for penetrating the neck of the capsule 13.
  • This broaching tip 15 connects the inseated in the precision bore 30. bears against the bush 26 due to the pressure in the high-prcssure part II of the valve. since the gas space at its low-pressure part N is'connected via its 'central bore and'the annular space between'the external profile of the bush'26 and the bore 30 with the low-pressure chamber and is thus practically pressureless.
  • a bore b which extends through the valve body 8, is provided in front of the sealing and closure screw 17. This bore extends downwardly at an inclination and connects the gas inlet chamber or the central bore 2 with the high-pressure chamber H behind the closure cap 31.
  • a transverse bore is connected to the axial bore of the rod 28 and is arranged in the part of the pull rod 28 in front of the O-ring 27.
  • a second transverse bore of the pull rod 28, which likewise communicates with the axial bore, is disposed in front of the membrane mount 24. and communicates the axial bore with the low-pressure space N.
  • an oblique bore a leads upwardly from this low-pressure or membrane chamber N and terminates behind the closure screw 17 in the central bore Z.
  • the hollow space behind the closure screw 17, that is to say the space which forms part of the low'pressure chamber. is connected with a precision nonreturn valve I8.
  • a precision nonreturn valve I8 At the region at which this nonreturn valve 18 meets the rising pipe or immersion pipe I, there is arranged the upper opening of the transition pipe 3 for the carbon dioxide.
  • the upper end of the transition pipe 3 is connected as, for example, by soldering into the rising pipe 1.
  • the latter pipe is sealingly mounted preferably with synthetic plastic material in the portion of the valve body 8 through which it extends.
  • the transition pipe '3 terminates shortly above the throttle 2. which is described further below.
  • the immersion pipe 1 extends into the closure of the barrel 4 so that the lower end of the transition pipe 3 extends slightly below the barrel closure 4 and, consequently, extends into the gas space which forms directly below the upper region of the barrel F The gas thus flows through the transition pipe 3 and first emerges below the closure seal 4 in the gas space of the barrel F to be tapped.
  • the pressure adjustment means are arranged in the form of a knurled knob 9 on the side of the valve where the membrane 25 is mounted.
  • the knob 9 is provided with index numbers.
  • a threaded pin is fixed by means of a tapper (FIG. 3) the free end of pin 20 being pointed and presses on the spring cup 22.
  • a helical spring 23 is seated on the spring cup 22 and is arranged between the threaded adjusting pin 20 and the membrane mount 24.
  • the membrane 25 is indirectly carried by a cap 21 which is fixedly screwed to the valve body 8.
  • the cap 2] has a counterthreaded bore opposite the membrane 25 in which the setting pin 20 is threadably mounted.
  • a pin 32 projects from the outer periphery of the cap 21 and thereby limits the angle of rotation of the setting knob 9 by engaging a projection 33 extending inwardly from the setting knob 9.
  • the conical connection 20 is loosened and the knob 9 is then turned to the corresponding position and is screwed tight.
  • the valve is thus adjustable within wide limits and can easily be adapted to all operational requirements.
  • a further essential feature of the tapping assembly is the throttle 2 which is screwed into the lower section of the tapping pipe 1.
  • This throttle 2 consists of a synthetic plastic resistant to the media in question, such as carbonic acid gas and beer, and enables the beverage standing at a relatively high pressure in the barrel, more particularly beer, to be tapped Y without it entirely foaming as it emerges from the tapping cock.
  • beer must be continuously maintained under its saturation pressure, in order that no carbonic acid gas, connected with albuminous and suspended materials, can escape.
  • the throttle pipe 2 is inserted in the lower part of the rising pipe 1.
  • the inlet and outlet of this throttle are conically formed and the average cross section of the throttle bore relative to the length thereof has a predetermined ratio, for example about 1.5: 100.
  • the diameter of the longitudinal bore in the throttle preferably tapers inwardly from the beer inlet side to the outlet side in the ratio of about 2:1, the bore diameter at its beginning and end widening greatly.
  • This throttle pipe insert 2 occupies essentially the entire length of the section of the immersion pipe 1 disposed in the barrel. Since the lower end of the throttle pipe 2 is used to cooperate in the tapping of the barrel, it is so constructed that when penetrating the barrel closure 4 a sliding through the packing ring seal 5 in the barrel closure 4 is facilitated. For this reason, the lower end of the wall of the throttle pipe 2 is advantageously conically tapered, as can be noted from FIG. 1
  • the narrow bore in the throttle pipe 2 which gradually tapers inwardly in an upward direction and which widens conically outwardly at its upper end to conduct the flow of the beer from the lower part of the barrel under pressure, throttles the speed of flow and prevents foaming of the beer. It is thus possible that, even with a short rise path, the beer can be tapped at its theoretical saturation pressure or even at a higher pressure, and thus the quality of the beer can be completely retained.
  • the barrel F is provided with a specially constructed closure 4 which facilitates broaching the barrel F.
  • the closure member 4 is screwed into a threaded member 6a arranged over a central upper opening of the barrel.
  • the barrel closure a flange portion 4b which has a pair of opposite recesses 40 adapted to receive mating projections 7b of the connecting member 7 so that the closure member 4 can be connected to the member 7 in bayonetlike fashion.
  • the connecting member 7 has, except the upper and lower portions thereof, preferably a cylindrical shape.
  • the member 5 is adapted to form a sealed joint around the pipe 1 when the latter has been passed therethrough.
  • the closure member 4 is hermetically sealed by means of a specially constructed sealing cap 35 (FIGS. 7 and 8).
  • a specially constructed sealing cap 35 (FIGS. 7 and 8).
  • a sealing gasket 6 is disposed between the flange portion 4b and the threaded member 6a.
  • connecting member 7 serves to maintain the entire tapping assembly in position over the barrel F.
  • the lower portion of the bore 4a has an indentation 4d into which is moved a mating projection 36 of the sealing cap 35.
  • the latter is slid into the bore 4a of the closure member 4 so that the projection 36 moves along a track formed by the indentation 4d. In this manner the sealing cap 35 can be firmly mounted in the closure member 4 and cannot be rotated therein.
  • the sealing cap 35 has essentially the shape of a hat, the flange of which has a broadened tongue-shaped portion 38.
  • the projection 36 extends from the opposite side of the sealing cap 35 along the entire height thereof.
  • the main body of the sealing cap is provided with a plurality of ridges C (FIG. 7) which serve to ensure a seal when the cap 35 has been seated in the closure member 4.
  • the roof of the cap 35 is slightly arched and is, preferably, provided with radial indentations 4 (FIG. 8) to increase the elasticity of the cap 35.
  • the roof of the cap 35 has a thinned circular section 39 at its center.
  • a rigid member 41 having the shape of a truncated cone, is firmly mounted inside the cap 35.
  • the member 41 has an upper pointed end 42 which extends close to the inner surface of the roof of the cap 35, more specifically, close to the inner surface of the thinned section 39.
  • a pressure equalization passage 43 is disposed in the rigid member 41 adjacent to the point 42 thereof.
  • the cap 35 When the barrel F is tapped as described above, the cap 35 is pushed out of the closure member 4.
  • the cap 35 is mounted in the lower portion of the bore 4a so that the roof of the cap 35 is positioned just below the cylindrical seal member 5.
  • the upper surface of the broadened tongue-shaped portion 38 of the sealing cap 35 bears against the bottom surface 4e of the closure member 4.
  • the pipe 1 presses down on the roof of the sealing cap 35 that it is deflected downwardly and the pointed end 42- comes to bear against the rigid truncated conically shaped member 41
  • An additional push of a relatively small force by the pipe 1 causes the cap 35 to be pushed out of the closure member 4.
  • the broadened tongue-shaped portion 38 causes the cap 35 to undergo a pivotal movement when it is pushed out by the pipe 1. thereby preventing the cap 35 to remain hanging on the pipe 1 or to close the opening of the pipe 1.
  • the scaling cap is made of a suitable plastic or synthetic material which does not deteriorate when stored in a carbonated bewrage. All of the portions of sealing cap 35 are made of relatively elastic material whereas the member 41 is made of stiff material.
  • the tapping installation 8 is lowered with the pipe 1 into the bore 4 u and pushed through the cylindrical seal member 5 of the closure member 4.
  • the pipe 1 traverses the seal member 5 and the lower end of the pipe 1 comes to bear against the roof of the cap 35.
  • the latter is then penetrated by the point 42 as described above after the seal member 5 has formed a seal around the lower end of the pipe 1.
  • the latter then pushes the cap 35 entirely out of the closure member 4.
  • the torque exerted by the tongue'shaped portion 38 prevents the cap 35 from closing the lower end of the pipe 1 during this pushing-out action.
  • the tapping installation is now introduced into the barrel F until the projections 7a of the connecting member 7 snap into mating recesses in the valve body 8 thereby positioning the latter over the barrel F.
  • the entire tapping installation can thus be firmly positioned over the barrel F and in the closure member 4.
  • the pipe 1 is sealingly engaged by the member 5 so that no pressure losses occur after the tapping installation of the invention has been installed.
  • the penetrating and pushing out of the sealing cap 35 is easily accomplished in a sanitary manner and presents no particular difficulties.
  • the connecting member 7 can be removed and reused over and over again.
  • a CO capsule. preferably containing l6 g. of gas. is used in the tapping operation.
  • This capsule 13 is inserted in the capsule container 10, the neck of the capsule extending somewhat from the receiving sleeve ofthe valve body 8.
  • pressure is adjusted by means of the setting screw on the adjusting knob 9 to a low value, that is to say to one of the index numbers I to 3.
  • the capsule container 10 with the capsule 13 is then screwed into the threaded sleeve of the valve body 8 provided therefor on the tapping device. After for example about two rotations, a first resistance is felt, which is rapidly overcome by forceful turning. By this means, the metal plate closing the capsule 13 is penetrated by the broaching tip provided therefor. By further turning, the capsule neck is moved onto the seal 14 and drawn forcefully thereagainst.
  • the path for the tapping gas is now free and the desired tapping pressure is then set to a value which has been obtained by stepwise further turning ofthe setting screw or which has been found to be advantageous from earlier tappings.
  • the CO gas standing at 60 atmospheres excess pressure flows through the bore in the broaching tip 15 into the pressurereducing valve, possible impurities being held back in the filter 16.
  • the highly pressurized gas passes into the bore i: in front ofthe closure screw 17, is obliquely downwardly guided and flows into the highpressure space H under the closure cap 31 (FIG. 3). From there, the gas flows through the narrow annular space between the valve shank 29 and the precision bore 30 where a pressure drop occurs as a result of the throttle ac tion taking place therein.
  • the gas then flows into the annular space between the valve shank 29 and the pull rod 28 and through a first transverse bore provided in that portion of the pull rod 28 which is disposed within the valve shank 29, from thence into the axial bore of the pull rod 28. From there the gas passes into a second transverse bore in the pull rod 28 which is disposed in front of the membrane mount 24, thus forming an outlet in the low-pressure space N, from whence the gas emerges from the valve.
  • the path of the gas is shown by arrows in FIG. 4.
  • the threaded pin 20 By rotating the setting knob 9, the threaded pin 20 can be axially reciprocally moved. This movement compresses the spring 23 to a greater or lesser degree, whereby correspondingly more or less pressure is necessary below the membrane 25 to overcome the spring force of the spring 23.
