Description

The The invention relates to a beverage dispenser with a Dispensing device with a dispensing head for accommodating an at least partially flexible dispensing line, and one containing a drink Container, in particular a carbonated acid Drink, while the use is connected to the dispensing line, the at a Outflowing a coupling element for releasable connection to the dispensing head having, wherein the coupling element has a shut-off valve for opening and Shut down the dispensing line, and wherein the dispensing head is an actuating element includes that to open and closing of the shut-off valve is connectable to the shut-off valve.

Such a donation device is out EP 246 052 A which discloses a container with a flexible tube placed in a dispenser with the tube in a vertical orientation. The liquid from the container, such as concentrated syrup, is dispensed by squeezing the tube. Around the tube may be clamped a spring element that can be actuated by the dispensing device to be opened. The known dispenser has a drawback in that it is not suitable for dispensing pressurized beverages such as carbonated beverages. The compression of the spout will, in the case of carbonated beverages, result in an undefined orientation of the spout and thus an uncontrolled direction of beverage dispensing. Further, squeezing the tube can result in undesirable gas leakage and foaming when carbonated beverages are dispensed. In addition, the known container can not easily be accommodated in a consumer environment because it has to be located above the glass into which the beverage is dispensed, in view of the gravity-induced current from the container.

A other beverage dispenser becomes in PCT / NL 99/00454. This known dispensing device comprises a cooling chamber, in which a container can be placed, which is a carbonated Drink, like beer, contains. The carbonated beverage containing Container comprises an outer, out Plastic manufactured container and an inner flexible bag in which the carbonated drink located. The flexible bag is via a filling and dispensing head with the Neck of the outer container connected. The dispensing head has a first, relatively wide filling channel provided on which a filling head a filling line can be connected to fill the flexible bag. To the filling and removing the filling head from the filling line becomes the filling channel of the filling and dispensing head closed by a spring-loaded valve. A second, relatively narrow dispensing channel of the filling and dispensing head is with connected to a flexible hose that extends at right angles to the longitudinal direction of the container extends. Before the container in the cooling chamber of Beverage dispenser is placed, the dispensing channel is closed by a spring-loaded valve. An existing plastic outlet component is under right Angle with a plate indicating a mark, and is fixed at the end of the flexible hose. This outlet component can in a receiving component in the dispensing head of the beverage dispenser to be placed. The dispensing head comprises two swiveling parts, the for limit the flexible hose a passageway, and a shut-off valve, which is connected to a tap handle. The shut-off valve includes a spring-loaded clamping mechanism, the operation of the Zapfhandgriffs is capable of the flexible hose in the duct on the one hand by squeezing shut down and release it.

After this the flexible hose has been placed in the passageway, the dispensing head is closed and the dispensing handle is closed Position brought. Then a cover can be attached to the dispenser can be closed and can be a pressure-increasing device, like a Compressor, to the container be connected to the space between the wall of the outer container and the flexible bag to introduce a print medium. By closing the Cover the cooling chamber in the dispenser, the dispensing channel of the filling and Spend head opened, so that the contents of the flexible bag in the flexible hose to be driven. The flexible hose is released by opening the Zapfhandgriffes and then takes his free, not deformed Cross section, and the carbonated drink is discharged under pressure from the dispensing head. The known dispensing device is also with a cooler for cooling of the drink, as with a Peltier element.

The known device has the disadvantage that a controlled Delivery through the flexible hose is possible only to a limited extent, and that the output is dependent is from the flexible characteristics of the hose. If the drink is a carbonated drink is, like beer, this may be more desirable Cause foaming.

If the dispensing handle is not closed when the container containing the beverage is placed in the dispenser, undesired dispensing of the beverage may occur in the known dispenser. Furthermore, it is the Drink also possible to leach out of the dispensing line when the empty container is removed from the dispensing device. As a result, the dispensing head and other components of the dispenser can become dirty. Consequently, the known device must be cleaned relatively frequently. In addition, as a result of contamination, the life of the beverage can be shortened.

Finally, can after dispensing a lot of the drink and after closing the dispensing handle from the part of the flexible hose that is downstream of the shut-off valve is arranged over a extended Period drink continue to lick it.

One The aim of the invention is to provide a beverage dispensing device, as well as a container and a dispensing line of the aforementioned type, in which these problem solved are.

One Another object of the invention is to provide a beverage dispensing device which requires very little maintenance, requires little cleaning, and with a relatively long life for the drink creates a hygienic environment.

In this regard is the beverage dispenser according to the invention characterized in that the coupling element is a substantial rigid tubular Outflow member to be positioned in the dispensing head, wherein the shut-off valve has a closing member which is relatively to the tubular Outflow member through the actuator can be relocated to open or close the spout, without the diameter of the flexible part of the dispensing line substantially to reduce.

There the coupling element of the dispensing line, which in the dispensing head in a unique position can be placed with a shut-off valve provided a controlled delivery of the drink can be achieved become. If a carbonated drink is spent, such as beer, can cause unwanted foaming This agent can be counteracted, since at the outflow channel no caused by a squeezing effect dimensional changes occur. This leads the delivery to a controlled outflow and a controlled Foam formation. Furthermore, and in contrast to the squeezing of the known ones flexible dispensing line, can the flow characteristics through the dispensing line according to the invention by dimensioning the dimensions and the stroke of the shut-off valve be set. The Zapfgefühl, the flow rate and the type of the jet of drink can be accurately adjusted by this means.

The Beverage dispensing device, the container and the dispensing line according to the present invention are useful for Edition of all types of drinks, However, they are especially useful for Dispensing carbonated Beverages, like beer. In the illustrative embodiments described below For example, reference is made to carbonated beverages.

Farther the shut-off valve can be closed when the carbonated drink container is placed in the dispenser, so that a leakage of carbonated drink is prevented, even if the dispensing handle in the open Position should be. When the shut-off valve is closed, as soon as the empty or partially empty container from the dispensing device can be taken, a leakage of the drink, which is in the flexible dispensing line is present, can be prevented from the dispensing line. It results that a beneficial microbiological environment is maintained, and the need for a common one Cleaning the dispenser decreases. Finally, as a result of use the shut-off valve in the dispensing line a relatively simple filling and dispensing head for the carbonated Containing beverage container which filling and dispensing head is equipped with a dispensing channel with a simple closure, e.g. a breakable seal being opened after the container is placed in the dispenser, and which closure can not be closed then.

The Donor line can have a rigid training, but can also be telescopic or at least partially a flexible training to have. The latter is preferred since this is the positioning of the shut-off valve simplified in the dispensing head. It is preferred, the dispensing line so that it extends transversely to or above the container, and to make them of flexible plastic, making them a disposable one or partially disposable conduit constituted, thrown away after being used once or more than once.

The Dispensing line can be permanent with the carbonated beverage containing container However, it can also be used for a detachable connection with the container be provided a clutch.

The shut-off valve may be a normally closed shut-off valve, a slit valve in the flexible hose that can be opened by compression through the dispensing handle, or a separate plastic shut-off valve with a closed balance position, a spring-loaded tetes (ball) valve or an electromagnetic valve. However, the shut-off valve may also include a tap or a valve, as known in the art, and may be provided with a control that allows it to be opened and closed by a user after being placed in the dispensing head.

Preferably However, if the shut-off valve is not equipped with a control for the user, but the dispensing head comprises a control element that with a Handle or knob is united, and with which the shut-off valve solvable can be connected, so that the shut-off valve itself small Dimensions may have. This offers the advantage that the shut-off valve is not only a light weight training and a small number of components has, making it easy as a disposable disposable item can be made but that it is also housed in the container, stored and transported, it being possible to For example, the dispensing line in the wound state above or to accommodate below the base of the can, which is the carbonated one drink contains.

When Result of the relatively small dimensions of the shut-off valve, which, preferably, has a cylindrical cross-section which is not is much bigger as the outer diameter the dispensing line, the shut-off valve can easily by a - optional cooled - guide tube a beverage dispenser carried out which is a type in the patent application number 1 015 359 entitled "Dispensing device and container therefor, as well Process for their production ", and which was filed on 31.05.2000 in the name of this applicant. In such a dispensing device with a guide tube, the compartment comprises to accommodate the carbonated drink containing a refrigerator which is placed below a bar, with the flexible Dispensing line from the fridge extends to the pump which carries the dispensing head. If a new container is connected with an associated dispensing line, which in this case a length of 1 meter or more, the stop valve may be at the end the flexible dispensing line easily through the guide tube to the dispensing head be pushed.

The Dispensing line opens and closed by relative rotation, translation or a combination of it, the pods, and by the operating element of the shut-off valve. An easy Shut-off valve, which is reliable in operation, has sleeves on, which moves in the rich direction of the dispensing line in relation to each other can be. With such an "In Line "-Absperrventil may be the pressure of the carbonated drink an additional closing force generate and can be a simple control element in the dispensing head for one accurately adjustable hub can be used for one simple tap handle can be adjusted, and can the size of the shut-off valve small stay.

By Using a "can" shut-off valve, which are opened and closed in the axial direction of the dispensing line can, and which shut-off valve by the pressure of the carbonated drink pushed into its closed position, becomes a simple, Compact shut-off valve made reliable and reliable in operation for one Disposable is appropriate, and easily fitted into the dispensing head and can be easily taken from it.

Of the Dispensing head may have a base section in which the shut-off valve can be placed. The shut-off valve can be provided with a protective cap which interacts with the base section such that the Shut-off valve enclosed between the base section and the protective cap and for the user during not accessible for use is.

Of the Dispensing head is, preferably, divided into two halves, which in relation are mutually pivotable and limit a passage, in which the donation line can be placed.

Preferably, the pivotable halves are provided with a locking mechanism which only can be solved when the shut-off valve is closed.

The Outlet end of the dispensing line, which downstream of the shut-off valve can be arranged from a relatively rigid plastic section exist, with a circumferential groove or a flange, the exact Position the end of the dispensing line with a complementary flange or a groove in the dispensing head cooperates. If through the dispensing head a cooling Medium performed As described in the patent application no. 1 015 359, the filed on behalf of that Applicant on 31.05.2000 the dispensing head shut off by the dispensing line, such that he at least at the time, at which the donation line out the dispensing head exits, at least partially fluid-tight.

The Outlet end of the dispensing line may be provided with a plate which, for example, carries the trade name of the beverage. This plate can be in one Chamber be fitted into the dispensing head, which chamber with a Window is provided, through which the plate is visible to the user. By this means, the contents of the carbonated beverage containing Container placed in the dispenser easily be determined.

Finally is in one embodiment the shut-off valve with a vent which is closed when the shut-off valve is open, and which connects the outlet end of the shut-off valve with the environment, when the shut-off valve is closed. This will be a negative pressure degraded after dispensing a drink and then completing the Shut-off valve could occur so that every drink downstream of the closed shut-off valve from the outlet end of the Dispensing line without significant dripping is delivered quickly.

1 shows a beverage dispenser 1 that with a dispenser 2 with a cooling chamber 3 equipped by a cover 4 can be completed. A container containing a carbonated beverage 5 is in the cooling chamber 3 placed. In the embodiment described below, the carbonated beverage is beer stored in a flexible bag 6 of the container 5 is contained under an overpressure of between 0 and 3 bar, for example 1.0 to 1.5 bar (the equilibrium pressure of CO ₂ over beer). However, the package may also contain other carbonated beverages, such as non-alcoholic beverages, under pressures generally between 0 and 5 bar gauge.

The flexible bag 6 is in an outer rigid container 7 of the container 5 housed and is close to a neck on a flat lip 9 a filling and dispensing head 10 fixed to create a seal. The filling and dispensing head 10 has an air duct 11 that with a pressure line 12 in the cover 4 can be connected, which pressure line with a compressor 13 connected is. Instead of a compressor, it is also possible to use a different pressure medium, such as a precompressed gas, for example compressed air or pressurized CO ₂ , which is supplied by a separate cylinder. When you close the cover is a spring-loaded valve 14 of the filling and dispensing head 10 moved down, leaving an outlet 15 uncovered and an air duct opened in the head 10 to the room 16 between the flexible bag 6 and the rigid container 7 leads, which air duct with the pressure line 12 is in communication.

To the filling and dispensing head 10 is a flexible dispensing line 17 connected, and if the container 5 in the cooling chamber 3 is placed, this is done with a dispensing head 18 connected. The donation line 17 includes a stop valve near an outlet end 19 , which shut-off valve 19 in the donation head 18 is removably fitted, which is in a normally closed position. If the container 5 in the dispenser 2 placed and the cover 3 is closed, as a result, the compressor becomes 13 turned on, is the shut-off valve 19 closed and, as a consequence of the pressure applied by the compressor 13 in the gap 16 is built, the beer from the flexible bag in the flexible pipe 17 against the shut-off valve 19 driven. By pressing a handle 20 can the shut-off valve 19 , which is an integral part of the donation line 17 is open, and can be beer from the bag 6 be tapped. If the container 5 has been emptied, or if another beverage container is placed in the dispenser, even if the container should still be partially full, the container 7 and the flexible dispensing line 17 with the closed shut-off valve 19 that are associated with it, from the cooling chamber 3 away. The container 7 of the empty container 5 which, for example, can be made of a plastic such as PET or ABS, can be reused while the flexible bag 6 , the filling and dispensing head 10 and the flexible line 17 with the shut-off valve 19 can be designed for a single use and discarded or recycled after use. For further details of the beverage dispenser 2 is referred to the international patent application PCT / NL 99 / 00454 on behalf of this Applicant, the contents of which are hereby incorporated by reference.

2 shows an embodiment of a beverage dispensing device 25 In particular, it is convenient for use in catering facilities. The donation facility 25 includes a refrigerator compartment, or a refrigerator 26 , with a container 27 containing a carbonated beverage in it. The container 27 can comprise a double-walled container with a rigid outer housing and therein a flexible bag, as in 1 however, it may also comprise a metal container, such as a stainless steel beer keg known per se. The capacity of the container 7 can vary from a few liters to 50 liters or more. A compressor or a CO ₂ cartridge 36 is with the container 27 connected. Further, instead of a compressor or a CO ₂ cartridge, a cartridge containing carbon and CO _{2 may be} contained in the container 27 be placed to generate the desired pressure, as described in International Patent Application PCT / NL / 99/00144. The container 27 is via a flexible plastic dispensing line 28 with a donation head 29 connected. The donation head 29 is part of a beer tap 30 standing at the countertop of a bar 31 is fixed. An inventive shut-off valve 32 is at the outlet end of the flexible pipe 28 attached, which shut-off valve 32 by means of a handle at the end of the beer tap 30 can be opened and closed.

An unillustrated cooling element is inside the refrigerator 26 which cooling element cools the air in the refrigerator, for example to 5 ° C to 10 ° C. By means of a blower 34 gets warm air from the hollow beer tap 30 back to the fridge 26 sucked. About a guide tube 35 in which the flexible dispensing line 28 is housed, and soft in the dispensing head 29 opens out from the fridge 26 in the guide tube 35 around the donation line 28 cold air, as a result of this way in the dispensing head 29 produced negative pressure. The beverage is cooled in this way, for example, to 8 ° C. The apparatus described above is described in more detail in Dutch Patent Application No. 1015359, filed on May 31, 2000, in the name of this Applicant, entitled "Dispensing Apparatus and Containers Therefor, as Well as Methods of Producing the Same".

3 shows a longitudinal section of the dispensing head 29 according to 2 , The handle 33 is with a housing 43 so united that it is about a wave 40 can rotate and over a spring 57 and a lead 57 ' on the actuator 45 attacks to the shut-off valve 32 to open and close. The free stroke of the handle 33 can be adjusted by positioning the tab 57 ' with respect to the actuator 45 , In the in 3 the position shown engages the projection 57 ' directly on the actuator 45 on, leaving the shut-off valve 32 by a small movement of the handle 33 opened and closed. By replacing the projection 57 ' against a lead 57 ' , which is arranged further to the right, compared with the projection in 3 , is it possible that the handle 33 performs a larger free stroke before it on the actuator 45 attacks. This allows a complete opening and closing of the shut-off valve 32 with a big stroke of the handle 33 be achieved, as with 90 °. The stroke of the handle can be between the relative small stroke (eg 10 °), as in 3 shown, and a relatively large stroke, such as 90 °, by simply changing the projection 57 ' be set.

By the spring 57 is a certain movement of the handle 33 possible without this leading to a movement of the actuating element 45 would lead, and will play the game when turning the handle around the shaft 40 eliminated.

An outlet end 41 the flexible dispensing line 28 passing along a curved path through the dispensing head 29 is conducted in the seat 42 enclosed by the dispensing head. The outlet end 41 , which is made of rigid plastic, is with a circumferential groove 52 provided, in which an edge 53 of the seat 42 of the dispensing head 29 occurs to a rigid enclosure of the outlet end 41 to achieve.

The donation head 29 includes a fixed lower section of the housing 43 with which a cover 44 between a closed position and an open position in which the outlet end 41 and the shut-off valve 32 the line 28 in the donation head 29 can be placed, pivotally connected.

The actuator 45 includes an essential horizontal arm 46 by a first end so with a pin 48 united is that he can swing. The flexible dispensing line 28 is about a leadership 49 in a curved path in contact with a curved end 46 ' of the actuating element 45 placed, taking the lead 49 at the top of the actuator 45 is appropriate.

Coupling means of the shut-off valve 32 which, for example, by a flange 51 on a sliding sleeve 61 are formed with a coupling element at the end of the curved end 46 ' of the arm 46 connected. The coupling element may be useful as a fork 63 be formed, which behind the flange 51 the shut-off valve 32 intervenes.

4 shows the on the handle 33 fixed wave 40 for moving the actuating element 45 , The wave 40 is at one end with a spring latch 47 provided a tooth 38 ' that's at the end of the wave 40 runs at a right angle. The hinged cover 44 of the dispensing head 29 has a complementary tooth 38 that is attached to the tooth of the spring latch 47 attacks. When the handle 33 in the upright position, in which the shut-off valve 32 is closed, is a disconnect cam 39 who is equal to the wave 40 is connected, so positioned that the spring latch 47 can be depressed, and the tooth 38 ' into the female cavity in the disconnect cam 39 incident. This position is in 4 shown so that when the shut-off valve 32 is closed and the handle 33 in the upright position, the cover 44 the lower section of the housing 43 can be solved, and is able to handle the hinge pin 60 aufzuschwenken.

How out 5 it can be seen, is the shaft 51 ' of the handle 33 in a recess in the wall of two concentric annular sleeves 55 . 56 accommodated. By rotation of the sleeve 56 about its axis with respect to the sleeve 55 , or by completely omitting the sleeve 56 , it is possible the stroke of the handle 33 between, for example, 90 ° and 10 °, over which there are openings in the walls of the rings or sleeves 55 . 56 is allowed to either be aligned with each other, or to move in a mutually offset position.

At the top of the actuator 55 is a stop 58 designed, against which stop the shut-off valve 32 when inserting the dispensing line 28 in the donation head 29 through the in 2 shown guide tube 35 comes into contact with too far pushing the shut-off valve 32 through the donation head 29 or beyond this is prevented.

Further shows 5 a spring element 51 '' that with the cover 44 connected to the cover when operating the spring latch 47 and unlock the cover 44 to move to the upright position.

Out 5 it is clear that the end 46 ' of the actuating element 45 the shape of a curved saddle has the flexible line 28 with no loops or sharp kinks from a horizontal to an essentially vertical position, with the saddle in a fork 60 leaking, in which the flange 51 the inner sleeve 61 the shut-off valve 32 can be placed. As a separate component is in the seat 42 a pinching spring 62 fitted to the shut-off valve 32 so position it in relation to the seat 42 is clamped when the cover is open, leaving the cover 44 can be closed. Through this arrangement form the edge 53 at the seat 42 and the circumferential groove 52 the outlet end 41 a relatively airtight closure, by the intake of air past the outlet end 41 in the cooled beer tap 30 counteracted.

The closed shut-off valve 32 prevents beer from entering the guide tube 35 licks when the dispensing line 28 introduced or withdrawn, being able as a result of its rigidity is the shut-off valve 32 and the outlet end 41 through the guide tube 35 push through. After that, the inner sleeve 61 placed in its extended position when the shut-off valve 32 in the fork 63 introduced or removed from the fork 63 is removed, leaving the shut-off valve 32 closed is. As a result of using the dispensing head 29 in cooperation with the flexible donation tube 28 , which is near the outlet end 41 with the shut-off valve 32 can provide a quick and easy positioning of the dispensing line 28 take place, so that an empty container for a carbonated beverage can be easily replaced by a full container. Because during this operation the whole donation line 28 is also replaced, frequent cleaning of the dispensing line is no longer required, which has the effect of saving considerable time and money, especially when pouring beer.

6a shows the plastic outlet end 41 the flexible donation tube 28 that with the shut-off valve according to the invention 32 is provided. How out 6b can be seen, includes the outlet end 41 an external sleeve 70 in which an inner Ver locking projection 71 is housed. The closing lead 71 is with crossways 72 equipped to allow the carbonated beverage from an upstream channel section 73 the shut-off valve to a downstream outlet section 74 go through. An inner sleeve 75 into which the flexible dispensing line 28 is welded in, is in the outer sleeve 70 so housed them for the lead 71 can slide. The outlet 73 ' the inner sleeve 75 has a sealing wall 76 with a height corresponding to the height of the projection 71 ,

In the in 6b shown position is the sealing wall 76 the outlet 73 ' the inner sleeve 75 with the lead 71 in contact so that a seal is produced. In the shut-off position, as in 6b shown are openings 77 in the wall of the intermediate sleeve 78 which the lead 71 carries, uncovered, leaving the downstream exhaust duct 74 over the openings 77 around the top of the outer sleeve 70 is vented (see the diagrammed arrows), so that in the exhaust duct 74 can not build a vacuum. If a shut-off valve 32 is closed, such a negative pressure would give rise to a long-term Nachleckage the carbonated drink from the outlet channel 74 which is undesirable. This is through the vents 77 prevented according to the invention. In the position shown, the sealing effect of the sleeve 75 reinforced by the pressure of the carbonated drink, which the sleeve 75 pressed into the closed position.

On the outlet end 41 is a sealing cap 80 with a rounded tip, take care to prevent the shut-off valve 32 when inserting the dispensing line 28 in the donation head 29 is contaminated, and to achieve a more uniform guidance of the shut-off valve 32 through the guide tube 35 , The sealing or protective cap 80 is from the outlet end 41 removed before the outlet end 41 in the seat 42 is placed.

The 7a and 7b show the shut-off valve 32 in its open position, with an end face 81 the inner sleeve 75 with a base of the intermediate sleeve 78 is in contact. In the position shown is the upstream channel section 73 in fluid communication with the downstream exhaust passage 74 the shut-off valve 32 , Because the front end of the sealing wall 76 the inner sleeve 75 with the intermediate sleeve 78 is in contact so that a seal is produced, carbonated beverage is prevented from, to the vents 77 go through when the shut-off valve 32 is in the open position. The height of the sealing wall 76 is sized so that the vents 77 are completely shut off at a time when the part of the wall 76 still with the lead 71 is in contact so that beer is therefore unable to pass through the outlet 72 withdraw.

The inner sleeve 75 is at its end with a flange 79 provided in the fork 63 of the actuating element 45 can be accommodated. With this arrangement, the outer sleeve 70 over the circumferential groove 52 firmly clamped in the dispensing head, and becomes the play for an axial movement of the inner sleeve 75 by means of the flange 79 through the flexible nature of the line 28 which is capable of yielding sufficiently to make a stroke of a few millimeters, such as about 4 mm, which stroke for the inner sleeve 75 is possible.

The 8a to 8d show different alternatives of the shut-off valve 32 according to the present invention, wherein the same reference numerals are used for identical components as in the 6 and 7 ,

8a shows an embodiment in which the outlet 72 in a central constriction of the external sleeve 70 is arranged. The inner sleeve 75 with the flexible line fixed thereto 28 , is placed inside the outer sleeve so that it can be moved, having at its end a sealing projection 71 has which sealing projection 71 by retracting the inner sleeve 75 in sealing contact inside the outlet 72 can be placed.

8b shows an embodiment in which the outer sleeve 70 with a sealing projection 71 and with an outlet 72 is provided to wel lead an outlet 73 ' in the inner sleeve 75 can be positioned to produce a seal. With this arrangement, the wall of the outlet engages 73 ' at the projection 71 so that a seal is produced, the projection 71 in the outer sleeve 70 is arranged in a fixed position. This will be the outlet 72 through a sidewall section of the inner sleeve 75 completed.

8c shows an embodiment in which a projection 71 on the inside of the outer sleeve 70 is arranged to which projection 71 Sidewall sections of the inner sleeve 75 are arranged, which are about the projection 71 extend in the downstream direction. The front wall sections can be around the projection 71 be positioned to produce a seal by retracting the inner sleeve.
