Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a method for guiding a dispensing line through a dispensing line channel in an assembly for dispensing beverage. The invention also relates to an assembly adapted for guiding a dispensing line through a dispensing line channel.

BACKGROUND OF THE INVENTION

In the art of beverage dispensing devices, techniques have evolved over the years in methods for connecting equipment, such as pressurized chambers via beverage dispensing lines through dispensing line channels to dispensing taps. The techniques involve lifting and maneuvering of heavy and bulky beverage containers and managing of parts such as lids, dispensing lines and empty containers. Recently a new kind of dispensing assembly has been introduced, some of these assemblies comprising exchangeable dispensing lines which are replaced together with the replacement of beverage container. A dispensing line connects a beverage container with a dispensing tap and is generally led through a protective shielding such as a dispensing line channel.

When replacing a beverage container in a pressure chamber the process includes disconnection and removal of a used dispensing line as well as connection of a new dispensing line. The procedure further involves the introduction and leading of the dispensing line through a dispensing line channel and the connection of the dispensing line with a dispensing tap and the new beverage container.

The methods used today are afflicted with installing difficulties as well as problems with cleanliness and hygiene.

Furthermore, the job is often carried out in environments where stress and hastiness contribute to making errors, sometimes costly, sometimes influencing the quality of the beverage when served to customers.

More specifically, the process of introducing a dispensing line into a dispensing line channel and connecting the dispensing line to a dispensing tap and a beverage container is associated with a number of drawbacks. For instance, the dispensing line is difficult to introduce in the openings of a dispensing line channel. The process of finding the entrance for the dispensing line to be guided through is further complicated by the frequently poor lighting conditions in the environments of bars and the like. Furthermore, due to the number of items to maneuver with the dispensing line easily becomes squeezed or clamped between the lid and the walls of the pressure chamber. Furthermore, after the lid has been separated from the pressure chamber it is put away and easily forgotten when assembling the system. Furthermore, the separation of the lid may cause it to end up on the floor or elsewhere where it is exposed to contamination. Furthermore, the number of loose items to manage in the process increases the risk also for the dispensing line or other parts ending up in contaminated areas. Hence, there is a need for the provision of a solution to the above stated shortcomings of the techniques used today.

It is an object of the present invention to overcome drawbacks of prior art solutions, and to provide a flexible dispensing assembly which is easy to use.

SUMMARY OF THE INVENTION

According to the present invention there is provided a method for guiding a dispensing line through a dispensing line channel in an assembly for dispensing beverage. The dispensing line channel has a first end in a tower and a second end arranged in connection with a cooling chamber. The cooling chamber comprises a pressure chamber having a lid with an opening for the dispensing line. The pressure chamber is further adapted during operation to accommodate a beverage container. The method comprises the steps of:

opening the lid of the pressure chamber,

aligning the opening of the lid with the opening of the second end of the dispensing line channel, and

guiding a dispensing line through the opening of the lid and the second end of the dispensing line channel, further through said channel and out of said first end of said channel or the reverse direction.

By this procedure the dispensing line only needs guiding through one opening, namely that of the lid.

According to one embodiment of the invention, the method may further comprise one or more of the following steps:

loading a beverage container into the pressure chamber,

leading the lid from the pressure chamber along a dispensing line set up for operation in the assembly to the opening of the second end of the dispensing line channel,

attaching the lid to the second end of the dispensing line channel by having connection between complementary connecting means on said lid and said second end of the dispensing line channel,

leading the lid from the alignment with the second end of the dispensing line channel along the dispensing line to the pressure chamber, closing the pressure chamber, and/or

removal of a dispensing line from the dispensing line channel and/or the beverage container from the pressure chamber.

Attaching the lid to the end of the dispensing line channel ending in the cooling chamber provides a natural, intermediate storage and there is no risk of forgetting to guide the dispensing line through the opening of the lid. The process of guiding the dispensing line is thus made comfortable and hassle-free with ergonomic operating positions, especially due to an elevation of the dispensing line channel above the floor. Furthermore, the risk of contamination is considerably reduced by this enhanced process. There are fewer loose parts to manage and maneuver with and the convenient multi-purpose position for the lid is at a safe distance away from contaminated environments such as a bar counter or a floor.

In a further embodiment of the invention, the lid is detachable from or pivotally attached to the pressure chamber.

Preferably, the connecting means are arranged for coaxial alignment of the opening of the lid with the second end of the dispensing line channel. A well-defined coaxial alignment together with correspondingly shaped and aligned cross sections of the openings in the lid and the dispensing line channel provide a connection with a smooth junction for the dispensing line to pass.

According to a second aspect of the present invention there is provided an assembly for dispensing beverage comprising

a pressure chamber having a lid,

said lid comprising an opening for a dispensing line;

a dispensing line channel having a first end in a tower and a second end arranged in connection with a cooling chamber, and

said pressure chamber further being adapted during operation to accommodate a beverage container, wherein the assembly comprises means for aligning the opening of the lid with the opening of the second end of the dispensing line channel so that the opening of the lid can be used as a guiding element for the dispensing line.

Preferably, according to the second aspect of the invention the opening of the lid of the pressure chamber is essentially centered.

The assembly according to the second aspect of the invention may comprise a lid, which is detachable from or pivotally attached to the pressure chamber. By having the lid connected to the pressure chamber in its open state, such as by hinge means, the number of individual elements to handle is restricted and as a result, the process of replacing a beverage container is thus improved.

The lid and the second end of the dispensing line channel in the assembly according to the second aspect of the invention may further comprise connection means that are complementary to each other and adapted to attaching the lid to the second end of the dispensing line channel.

Preferably, according to the second aspect of the invention the connection means are arranged for coaxial alignment of the opening of the lid with the second end of the dispensing line channel.

The connection means of the lid and the second end of the dispensing line channel according to the second aspect of the invention may further comprise a threaded socket, snap connection, a catch, a bayonet coupling, a hook, a jig or any combination thereof.

According to the invention, the lid may further comprise guiding means for guiding a beverage container into position in said pressure chamber during operation. Preferably, the opening is arranged in the guiding means and the guiding means is floating suspended. The term “floating suspended” is in this context to be construed as having the guiding means movable in a lateral and axial direction, preferably so as to enable various angular directions of the guiding means in relation to the lid. The axial direction being along the longitudinal elongation of the pressure chamber and the lateral direction in a direction perpendicular to the axial direction. The degree of maneuvering freedom of the guiding means may further be restricted to pre-determined distances.

The guiding means provides an expedient way to secure that any misalignment, which may exist between the opening of the lid when the lid is placed and locked on the pressure chamber and the dispensing line is overcome. Thus, it is also avoided that the dispensing line will be squeezed or get caught between the lid and the beverage container.

The lid in the assembly according to the second aspect of the invention may be made of a material such as metal, plastic, carbon fibre or the like.

Additionally, the lid according to the second aspect of the invention may further comprise a handle.

Furthermore, the lid according to the second aspect of the invention may comprise elements arranged to guide the dispensing line upon entry into the opening of the lid, such as a funnel-like portion.

The lid 5 has been detached from the pressure container and is led along the dispensing line 18 to the opening 8 of the dispensing line channel 7 where the opening 19 of the lid 5 is aligned to the opening 8 of the dispensing line channel 7. A slight pressure applied to the lid 5 activates a snap connection attaching the lid 5 to the dispensing line channel 7.

FIG. 9 shows a view of the tower 10 as shown in FIG. 1 with a dispensing tap 11 with a tap actuator 12 and a dispensing line 18 where the dispensing line 18 is released from the dispensing tap 11 on the tower 10.

In FIG. 10a it is shown how the dispensing line 18 is retracted from the dispensing line channel 7 by gently pulling it out through the opening 19 of the lid 5. FIG. 10b then illustrates how the used beverage container 14 easily is removed from the pressure container.

FIG. 11 a shows the release of a container 14, preferably a pre-cooled one, from its transport packaging. The container 14 is then inserted into the pressure chamber 4 as shown in FIG. 11b. In FIG. 11c the dispensing line 18 according to the invention is guided through the lid 5 and further through the dispensing line channel 7. The dispensing line 18 emerges from the dispensing tap 11 and is locked into a dispensing position as shown in FIG. 11d.

Correspondingly to FIG. 8 the lid 5 is led from the alignment with the end of the dispensing line channel 7 along the dispensing line 18 to the pressure chamber 4, closing the pressure chamber 4.

FIG. 12 a illustrates the locking of the lid 5 to the pressure chamber 4 which, according to a preferred embodiment is carried out by turning the lid 5 clock wise 360 degrees. After proper locking of the lid 5 is confirmed as shown in FIG. 12b, the pressure container is brought into position for operation, as shown in FIG. 12c. To prevent clamping or squeezing, the dispensing line 18 is attached, preferably to the connection means 9 of the dispensing line channel 7 as shown in FIG. 12d. A new container 14 is inserted in the cooling chamber 2 for pre-cooling as shown in FIG. 12e. Finally, the door to the cooling chamber 2 is closed and the dispensing assembly 1 will be ready for use in a few minutes after the correct operating pressure has been obtained.

FIG. 13-16 shows a sequence of unwrapping and introducing a new beverage container 14 in the pre-cooling section of the cooling chamber 2. FIG. 13 shows a protective box containing a beverage container 14. The box may be made of a material such as cardboard and it may further comprise handles as illustrated in FIG. 13. FIG. 14 shows how the box is conveniently opened by pulling a tearing string encircling the box. Thereby, the top part of the box is detached from the bottom part, lifted and removed, as depicted in FIG. 15. Hence, the top part of the beverage container 14 is revealed, thereby reducing isolating effects as well as making a subsequent loading of the beverage container 14 quicker and easier. FIG. 16 illustrates how the beverage container 14 is introduced in the pre-cooling section of the cooling chamber 2.

FIG. 17 shows a cross sectional view of the lid 5 of the pressure chamber 4 depicting guiding means 21 for guiding a beverage container 14 (not shown) into position in the pressure chamber 4 during operation. An opening 22 is arranged in the guiding means 21 for allowing floating suspension of the connecting means 17 for attaching the lid 5 to the second end of a dispensing line channel 7 (not shown) as well as for facilitating release of the beverage container from the lid after operation.

According to an alternative embodiment of the invention the dispensing line 18 is separated from the system and thereby has both of its ends free, allowing for free selection of the order in which the dispensing line 18 is connected to the dispensing tap 11 and beverage container 14 and guided through the lid 5 and the dispensing line channel 7. For instance, it could be that the dispensing line 18 is guided from the dispensing tap 11, through the dispensing line channel 7, through the opening 19 of the lid 5 and to the beverage container 14 placed in the pressure chamber 4.

In a further embodiment of the invention, the dispensing line 18 remains connected to the dispensing tap 11 and the dispensing line 18 is detached from the beverage container 14 only.

According to one embodiment of the invention, the lid 5 and the pressure chamber 4 are connected with hinge means 15. The hinge means 15 are thus so arranged as to provide automatic alignment of the opening 19 of the lid 5 with the opening 8 of the dispensing line channel 7 ending in the cooling chamber 2 when the lid 5 is in its open position during replacing of a beverage container 14.

The connecting elements of the lid 5 and the end of the dispensing line channel 7 ending in the cooling chamber 2 may comprise connection means 9 such as a bushing mechanism, a bayonet coupling, a hook, a jig, an o-ring, a hitch, hook or clutch or any combination thereof. Even though the methods and assembly 1 as well as the drawings disclose a valve connected to the outlet end of the dispensing line 18 and that said valve is replaced with the dispensing line 18 it is within the inventive idea that the valve also may be a separate valve which is not replaced at the same time as the dispensing line 18. Thus, the outlet end of the dispensing line 18 and the valve may comprise complementary connection means 9, which easily may be separated.

Furthermore, the outlet end of the dispensing line (as well as the inlet end if not mounted in the beverage container 14) may comprise a cap, hood or cover which easily may be removed after the guiding through the assembly 1 and just before the dispensing line 18 is mounted in the valve and beverage container 14, respectively. Hereby, it is obtained that the interior of the dispensing line 18 is kept clean and it is thereby avoided that the part, which come in contact with the beverage, is contaminated.

The valve (if placed at the dispensing line 18 before the guiding through the assembly 1) may also comprise a cap, hood or cover for the same reasons as mentioned above.

Although the invention above has been described in connection with preferred embodiments of the invention, it will be evident for a person skilled in the art that several modifications are conceivable without departing from the invention as defined by the following claims.
