EP1840044B1 - Drinking pouch comprising a movable bag for a dispenser - Google Patents

Abstract

The system has a motion unit that is displaced over a section (41`) in a pivoting end in a moveable manner, where the section lies within an outside of a moveable bag (10`) filled with beverage. Movement is transferred within an introduced section (42`) lying in a case of planar moveable parts (40`) on a beverage filling, under pulling movement of an inner case (20`). The inner case provided as a moveable unit is projected in an inside of the beverage filled bag and seals the planar moveable parts. Independent claims are also included for the following: (1) a bag of a beverage dispensing system (2) a method for operating a beverage dispensing system and for preparing cooled beverage for a portion wise dispensing from the dispensing system.

Description

The invention relates to a beverage bag as a flexible bag, which has a pocket and this bag allows for improved cooling ability of the filled beverage. As the outer packaging of the flexible bag is usually selected for the box-like container cardboard packaging, but this cardboard packaging is not a mandatory utensil, sondem the flexible bag can be delivered without this packaging, even without an already filled beverage to spot (where the drink used and / or filled and / or served) with beverage ingredients (beverage concentrate and water) to be filled.

Claimed is a dispensing system (claim 10), wherein in the flexible bag, a movable surface element is introduced and a method that can be interpreted either as a working method or as a use for the flexible bag (claim 2).

In the prior art beverage dispensing devices are generally known, which are filled with premix drinks, see. EP-B 793 618 (Wolfgang Jobmann ). Constant and essential requirements for these beverage systems is hygiene. By using disposable bags, this hygiene can be reasonably controlled, but the more hygienic these bags become and the more hygienic and aseptic the contents are packaged, the harder is the access or access of a suitable cooling mechanism for the correspondingly well sanitary shielded system.

In the prior art, two techniques are mostly used for the distribution and delivery of locally deployed delivery systems. On the one hand there are so-called bag-in-box devices in the business, which are filled with a bag-in-box drink. In a factory, a finished beverage is filled into bags, which are provided with a sealed discharge hose. The discharge hose is sealed by it. The drink is aseptically sealed and access to the drink in the carton is only possible if the place of delivery of the carton has been placed in a suitable refrigerator and the discharge hose is cut to remove the drink - after appropriate cooling - in chilled condition in portions can ,

Without an outer packaging, beverage systems work according to the "bag-in-bowl" principle. Here, the beverage bag is also provided with a discharge hose, but can be quite open, as well as a Einfüllende may be open for the introduction of beverage ingredients, preferably a concentrate and water, or an externally mixed beverage. At the point of issue, these bags are placed in a tub or container to be subsequently filled with the beverage ingredients. The output also takes place here from a suitable refrigerator to the system via the output tube, but not necessarily must be separated, but can be closed by inserting into the system-suitable refrigerator with appropriate output device by this output device by pressure, so that a filled drink does not automatically leak, on the other hand, the discharge hose but not separately cut must.

Both systems have proven themselves in practice, are also sufficient in terms of hygiene, but both are disposable systems. Due to the good hygiene the two systems have the disadvantage that they can not absorb enough cooling quickly. This capacity of cooling captures the need to be cooled down to a low temperature within the shortest possible time, based on the beverage fluid in the flexible bag (or even inside the bag and the outer packaging). In the closed bag and especially in the outer packaging, it is difficult for the beverage to achieve a time-effective cooling. It is therefore still necessary today to pre-cool the beverage contents of these systems over a longer period of time, either in a separate refrigerator in which the bag-in-box refills are first stored before they reach the dispensing appliance, or for a longer time in the dispensing appliance itself to be cooled, which have been briefly referred to above as "suitable refrigerators". Both precoolings require time on the one hand and increased energy consumption on the other hand, what the invention has taken up as improving.

US-A 3,463,357 (MacLean ) illustrates a flexible bag in an outer packaging, there x, which bag has a plurality of openings, which from there FIG. 2 most clearly. There is provided a filler opening which directly adjacent to a sample section having as bag attachment, there 20, a narrow inlet and a slightly wider interior, but in relation to the main bag has a very small size. Filled product, including liquids or ice cream, for example, are then not only in the main bag, there 10, filled, but also in the sample bag 20. Then the main inlet, there 18, closed, for example, hot sealed. One beside it arranged sampling nozzle is slightly spaced, not so close to the filling opening, as the sample bag, but has a much larger cross-section. He can, like the local FIG. 6 clarified, cut open to remove the contents. The sample bag can be separated without causing other access to the main bag, so also be sealed by a heat seal at the bottleneck, to then be separated, and to be able to remove samples of the contents. The said bag solution or bag thus has three accesses, two of which are permanently closed; one of them can be separated for samples and can not be opened, but the other can already be opened for removal. A direct application for the storage of drinks and the removal of drinks is not described there, nor is it stated that the contents of the bag quickly cool.

Comparable, but in a more remote area of the sterility of biological fluids is the US-A 5,685,875 (Hlavinka ), which also works with an appendix, which receives a part of the fluid and can be separated, see. local FIG. 2 , The hermetic separation and the physical separation of this smaller bag section guarantee that the sterility of the remaining product is maintained.

More in the direction of providing a mix of different content shows the bag shape of the US-A 3,430,815 (Weimer ), which is primarily aimed at mixing tartar and does not want to make the mixture in a separate container, but in the bag, which is first prefilled with Tartar sent to the catering company, where the tartar with the other additives gradually mixed together by filling the additives in another filling opening, which is previously separated. Afterwards, the bag is closed again to be kneaded together with the tartar in the bag and mixed, cf. local Figures 2 . 3 and 4 , The inlet is initially closed, then opened and receives the additives. The first stone, through which the tartar was filled, is designated there by 18 and is then, after filling, closed. The entire contents are dispensed after mixing through another outlet 16, which was initially tightly sealed. Again, similar to the aforementioned documents, a bag shape is described which has a plurality of openings and at least one outlet; which can be opened and closed at different times.

Finally, another bag with multiple inlets and outlets from the US-A 6,244,023 (Lataix ), which also has an inlet, a tapered location and an associated outlet. The inlet can be separated in order to be able to introduce the products and compressed air there, cf. there summary with column 3, lines 17 to 25. However, this form of the container and its use are far removed from the invention claimed here.

It is an object of the invention to maintain the hygienic performance of the prior art in the sector of drinks at least and to significantly accelerate the measures for cooling, respectively, to facilitate the cooling or to reduce the energy consumption during cooling. An acceleration of the cooling of the drink, reducing the cooling effort is part of the so circumscribed technical task.

The solution can be found by a doctrine according to claim 1 or 2. All these solutions have in common that the inner contents, so the beverage components of the bag in already inserted state in the dispensing device can be kept in motion. This movement can be described as stirring, swiveling or oscillating movement, it is a movement brought in from outside into the liquid, which does not lead to an impeller or stirring paddle or any other stirring device coming into direct contact with the drink, but rather via a Screen in the form of a bag is shielded from the bag material. The movement in the beverage is achieved without opening the closed bag and without the agitator getting in direct surface contact with the beverage. The zughörig trained pocket that either already protrudes into the drink, or only protrudes into the bag interior (when not yet filled state) or as a pocket still protrudes outward to be subsequently inverted into the inwardly projecting state, is an ingredient which allows this solution. In the then inwardly projecting inner pocket (claim 3) or inverted outer pocket (claim 4), the moving element is introduced here as a designated paddle element (claim 26), in order then via an introduced from outside this movement on the Mitbewegung the inwardly projecting pocket on the To transfer drink. The "stirring movement" of the beverage in the form of a back and forth pivoting of the paddle with pocket and a corresponding transfer of this movement to the entire liquid content provides for rapid energy discharge, in the form of a heat vent from the liquid, on the other walls of the bag or of the outer carton, on the inner wall of the moving liquid sweeps over faster and thus better able to dissipate the heat from the liquid content.

Since the planar movement element in the sense of the paddle element or wing is shielded in the drink and the fluid pressure of the beverage loads evenly on all sides, this liquid force is released during the movement of the wing and he can easily moved in the pocket and with the bag in the drink become. For overcoming only the force is necessary, which is transmitted by the movement of the paddle in the liquid as such, and this is proportional to the speed. So if the wing moves slowly, it brings a gentle, light and steady movement into the liquid. Thus, it allows the circulation of the liquid and the circulation on the inner walls of the bag, from where the heat discharge from the liquid can be done faster and more targeted, as if the liquid remains unmoved.

By the proposals according to the invention can be prevented that the motion introducing wings with the drink comes into contact and deteriorations are to be accepted, which are in a reduction of hygiene.

The direction in which the planar element is introduced for circulating, is relatively freely selectable. It can be inserted from the top, the planar element in the outgoing from above also bag, to which this bag has an outwardly projecting opening. The same can be done from all four sides of the bag, then it is a lateral introduction of Umwälzbewegungen, also on the shielding bag. An insertion from below is possible, at a distance from the output section (claims 22 to 24).

The claimed flexible bags have a capacity of between 10 liters and 20 liters, and are preferably filled from above. Preferably, the discharge hose is oriented downwards. The materials from which the flexible bags can be made are so flexible and preferably transparent that they have no rigidity and allow sufficient movement in the joint area where the inner pocket passes into the bag, which corresponds to the pivoting of the sheet member. The shapes which the bags may have are also relatively arbitrary, bag-shaped packages can be used, in the sense of a two-sided bulging rectangle or cuboid, or else a cuboid, which is preferably used in box-like outer packaging, or else cylindrical-shaped containers, which have an upper and lower planar plane, connected to a cylindrical shell. The walls of these shaped containers are usually very thin, but sufficiently stable to withstand the water pressure, unless they are supported by an outer packaging or are supported by the refrigerators or dispensers when bag-in-bowl containers are filled. In that regard, then only the sealing function of these thin walls is required, which help to ensure hygiene at the same time.

Polyethylene is a suitable material for the film material of the flexible bag. Other plastics can also be used if they are sufficiently flexible, at least in that section, by arranging the pocket into which the planar element brings movement to the transitional area which lies between the pocket and the remaining bag. This movement is relatively small at the outer edge when the axis of movement is close to the bag-pouch transition area such that the major movement is at the forward end of the panel and, consequently, the major movement of the inwardly-projecting pocket at its forwardmost end he follows.

Advantages achieved with the invention are that the cooling takes no more than two hours, usually even less, because after one hour, a bag-in-box system according to the invention or a bag-in-bowl system also according to the Invention is cooled down to a discharge temperature. In addition, no special cold rooms are needed because the cooling takes place in the dispensing unit and here the hygiene does not suffer.

The filled in the closed state and with beverage flexible bag is liquid-tight, with an attachment of an outer packaging and transport stable. The sealed dispensing hose can already be provided during the production of the bag and does not have to be additionally closed during filling. He is liquid-tightly arranged on the container and preferably protruding as a cylindrical sleeve member, wherein the projecting into the interior of the bag bag can already be inside the bottled beverage inside, then preferably reinforced by imported plate elements (claim 9 or 10 or 25), the insertion of the facilitate planar motion element at the site of the beverage dispenser. These plates may be formed of cardboard and contain two layers between which the sheet element is inserted. This can avoid that damage to the inwardly projecting pocket occurs.

The formation of the planar movement element may be spatula-like, ie with a forward tapering of its longitudinal edges, so that a Tapered portion, at the front flat end, without a hazardous tip (claim 8).

A pivot axis of this sheet-like element as a paddle element may be formed approximately in the middle of the length, but it is also an asymmetrical formation of two sections of this paddle possible, the outer portion has a shorter length than the beverage moving portion, and an outside lying drive device, such as a cam or eccentric, emits a movement on the drive surface as the drive section, which is then implemented on the axis as a pivot axis in an opposite movement of the paddle in the drink (respectively shielded from the projecting into the drink bag). The flexible bag is in any case impermeable to the drink, but the bag has an outwardly projecting opening to push the flat paddle element in the inwardly projecting bag can.

Another training with the bag-in-box system is also possible. The flexible bag does not yet need to protrude into the interior of the bag, but may continue to be arranged outwardly as a flap pocket or be attached flat on the outer carton, wherein it protrudes through the outer carton to the outside. The purpose to be carried out in the outer carton opening gap is later used to introduce the pocket designed as a pocket inside the filled bag, which can be done on the double plate elements (claim 6) to prepare the gap for the moving element to be introduced, or it can the flat element, the introduction of the outer bag in the everted, inwardly projecting state are made. In this case, the planar element is pushed together with the outer pocket through the gap of the outer packaging, in order to achieve the operating state.

In the bag-in-bowl arrangement, the insertion of the bag takes place before or after the filling of the drink, as described above, only without the outer packaging. Again, in the inwardly projecting state of this bag an outwardly open opening, usually slit-like, provided in order to be suitable and adapted to receive the sheet-like element for causing the movement.

The connection between the bag as either pocket or already inwardly projecting pocket (inner pocket) with the rest of the flexible bag can be done via a seam, which may be formed as a welded or sealed seam, but it can also be made a one-piece design of the bag, in which the bag is preferably outside the interior as a pocket, and later turned inside out.

Such a bag form is disclosed separately, has an opening portion, an output portion and a first outwardly projecting pocket, which is suitable and adapted to be everted in the interior of the bag, in which state it takes over the shielding of the planar paddle element at the site and for Ensures that hygiene is maintained, but cooling is accelerated by orders of magnitude, which also takes into account reduced energy consumption and reduces costs or storage for pre-cooling rooms.

It has been found from the above description that a moving unit is in the operating state, which form the inwardly projecting pocket and the flat moving element introduced into it as a paddle element. This movement unit (claim 6 and 7) provides the achievements of the invention.

The bag can be made larger in length than in its width (claim 13). The discharge section may preferably be formed tubular (claim 13). He also has a greater length than an associated diameter. The pocket may preferably have parallel longitudinal edges.

The bag may be bounded with the liquid-tight seam opposite the bag (claim 11), as explained in more detail above. Naturally, the seam is then also liquid-tight and provides an improved and mechanically more stable transitional zone in which internal flexing occurs in the bag material, but which can be greatly reduced as the axis of pivotal movement of the planar paddle member near the fluid-tight seam between the bag and the remaining bag is located (in the operating state of the delivery system).

FIG. 7

shows a variant of a flexible bag for beverage intake.

In the embodiments, the two systems of bag-in-box and bag-in-bowl are implicitly described. The execution of a flexible bag is common to both, once the bag is self-contained, and once in an outer packaging as a box, which can be regarded as a box-like container. Other outer packaging may be provided, but need not be explained in detail here.

It should be noted that the figures are of a schematic nature, that is, they are not reproduced true to scale with regard to their lateral and vertical extension, nor are they reproduced in terms of the thickness of the wall of the flexible container 10. Rather, it should be clarified, which possibilities of movement and the formation of pockets and spaces are given in the flexible container.

FIG. 1 is a possible first variant of a bag 10 ', which has an upwardly projecting opening 15' and a remote therefrom, initially outwardly projecting formation 20 'as a turn-up pocket in a first outer layer A. On the opposite end there is provided an output section 30 'which is closable but here shown open. Before filling this bag 10 'with a beverage or a mixture of the beverage components water and beverage concentrate, this bag is placed in a trough-shaped container, not shown here, in which the dispensing tube sealingly abuts an output device and the outwardly projecting pocket 20' in an inwardly projecting second state B is brought, the dashed in FIG. 1 is shown. The bag 20 'is here inverted. However, the inwardly projecting state B and the outward state A are generally understandable terms.

The described step of introducing a moving element of a planar nature is described in FIG. 2 illustrates in the bag assembly 10 'after FIG. 1 is shown in a trough-shaped receptacle 19. This receptacle is to be understood as a bowl and has here not shown cooling devices and other control units, such as such for the controlled release of the beverage G, which is in the bag 10 'stored, cooled there, was previously cooled down and hygienically stored. By the delivery device as a tube 33 'and a seal 32' of the discharge hose 30 'is connected to the outlet, where the control mechanism not shown here for the delivery of the beverage G is provided. For this purpose, the outlet 30 'has an inwardly projecting opening 31', which in FIG. 2 is shown closed, on a leadership and Guide element, which opens into the discharge hose 33 ', which is connected to said control means for the portion-wise delivery of the beverage.

The bag 10 'of FIG. 1 has a bag wall 10b, which surrounds the outer and here also a portion of the upwardly open filling opening 15 'limited. The outwardly projecting slip pocket 20 'in the position A is connected to the rest of the flexible container 10' via a flexible connection 70 'which surrounds the slip pocket at its lower end in the position A and at its upper end in the position B full extent. Here, a liquid-tight connection is provided, which allows a certain flexibility and permanent load in the sense of a movement to a limited extent. Before filling the beverage ingredients in the filling opening 15 ', the outer bag 20' is brought in accordance with the Stülppfeil S in the inward state. The invagination is done by hand, since all inner walls of this pocket are aseptically directed inwards and are not contaminated by a contact with the palm from the outside so that this change with the beverage filling in contact. It results in the position B of the inwardly invaginated bag, here it is an inside pocket or a turned-up bag, which is able to accommodate a single-surface movement element. This is then in the introduced position in the FIG. 2 shown, will be discussed in more detail.

The embodiment of the flexible bag after FIG. 1 is intended to hold a drink, stores this drink in the respective situation in a tub or a box-like container, and stores it there so long that it can be dispensed in portions over a long period of time. Cooling takes place before and during the portion-wise dispensing, which is provided by the beverage dispensing system as, for example, a refrigerator or a cooling device. The dispensing tube 30 'is closable, as explained, and the filling opening 15' is also closable. If the beverage ingredients have been filled into the flexible bag through them, then this opening 15 'is pinched off by a transverse force F, as in FIG FIG. 2 shown. The bag 20 'connected to the remaining bag 10', like the bag, is made of a liquid-tight material, for example polyethylene. The bag wall 10b is thin, may be considered flexible, and is supported by the container wall 19 when filled. It is liquid-tight and hygienic.

In the inwardly projecting state of the pocket 20 '(position B of FIG FIG. 1 ) and with introduced flat motion element after FIG. 2 arises one upwards protruding opening 21 ', which is bounded by the connection 70', for example as a circumferential seam or a circumferential seal. This opening serves to introduce the planar movement element 40 ', preferably before the filling of the beverage into the interior 10' a of the bag 10 ', in order to facilitate this introduction.

In the position located outside the remainder of the bag 10 ', the turn-up pocket 20' is designed so that it can be freely inverted into the interior of the bag 10 '. This can preferably be done before the filling of the beverage ingredients, but it can also be done afterwards, possibly with the addition of a flat support and stiffening device, as described later with reference to FIG. 5 is explained.

In the filled state after FIG. 2 The movement device 40 'and the inwardly projecting pocket 20' form a movement unit C.

This is in FIG. 2 Drawn filled the beverage G and the opening 15 'shown in the state of just closed becoming. In the case of a sealed content, the beverage can only be taken out via the delivery hose 33 ', in portions and on request. Previously, the device with the trough-shaped receptacle 19, the content G must cool down, to temperatures above 0 ° C and in an area below 10 ° C. This cooling does not take place without the influence of a movement which is introduced by the flat movement device 40 '. The existing movement unit C allows the planar device 40 'to move in the beverage G without it coming into direct surface contact with this beverage. The inner pocket 20 '(the inwardly projecting, everted outer pocket) protects the surface of the planar mover 40' in its lower portion 42 ', which reciprocates in a pivotal movement about the axis 51. This movement is transmitted via the outwardly projecting flat portion 41 ', wherein a drive means not shown here is provided, for example as a cam or eccentric, which brings a reciprocating motion on the upper portion 41'. Thereby, a back and forth movement is exerted on the lower portion 42 ', which, together with the pocket 20', causes the beverage G to move, which may be called rolling or stirring in the sense of a non-rotating movement.

The resulting motion potential in the beverage G allows all areas of the beverage to pass quickly and almost regularly past the wall portions of the tub 19, to be cooled there, and to further transfer this cooling to the interior of the beverage or to transfer them there by the movement of the paddle device 40 '. be moved. A much faster and more effective cooling by removing heat the inwardly projecting wall surfaces of the trough 19 can proceed. Times are reached which are less than two hours for cooling a beverage of a volume between 10 liters and 20 liters, with outlet temperatures above 20 ° C. First experiments with the embodiments of the invention, which are shown in more detail below, have resulted in cooling times which are smaller by a factor of 10 than those which are conventionally achieved by convection cooling.

In order for the movement means 40 'to perform the pivoting movement, an axle 50 is provided which is mounted on a roller bearing, the details of which are not shown here, but which provides an axis of rotation 51 which is coaxial with the shaft 50. Thereby, a movement directed in and out of the plane of the paper can be transferred to the upper portion 41 'in a correspondingly opposite movement on the inwardly projecting portion 41' which moves together with the pocket 20 'with the joint 70', either experienced as a real seal with a striped circumferential shape or as a pure transition compound in one-piece shaping an inner flexing or load, but which is low. The axis 51 is close to the sealing seam 70 ', so that there is hardly any movement on the bag and thus a slight risk of breakage or cracking of this portion of the liquid holding bag.

The execution of the turnout bag 20 'can be carried out either as a sealed bag with sealed seam or as welded inner bag, which then does not need to be everted, but already in a position B corresponding position within the interior 10'a of the flexible bag 10' located is.

The shape of the inwardly projecting bag 20 'is relatively arbitrary to choose, it is preferably longer (higher) than wide and here has a downwardly tapering shape with a flat end. The matching shape of the planar movement element in the second section 41 'is spatula-like. A preferred bearing is approximately in the middle along the total extension of both sections 41 ', 42', as is also shown substantially with the axis 51. This support with the axle 51 is also provided substantially in a region of the connection 70 of the flexible bag.

FIG. 3 illustrates another embodiment with an approximately cuboid outer carton having a greater height than width. This Outer carton 9 is provided as a box of a flexible bag, it is similar in structure and operates similar to that of the previously described embodiments. Here, the box-like container is provided with the flexible bag inside, and a beverage is filled in the flexible bag, which is already closed at the top. The use is the same, the beverage holding flexible bag is hygienic for the drink and the stability gives the outer packaging, which is also transportable.

A discharge section 30 is tubular and has an annular seal 32 surrounding an inner discharge opening 31 which terminates in the tube 30, which can be coupled to a dispensing system. For this purpose, the container 9 is inserted into a corresponding receptacle of a refrigerator or a cooling device, which is not shown, but which are generally known as dispensing systems. They provide cooling effects to cool the beverage in the interior of the flexible bag and provide delivery means for controlled, portion delivery via the delivery tube. The cooling effect is in the inserted state on the outer packaging or through them, and heat is taken out of the liquid inside to cool the drink down to a temperature of below 10 ° C.

The filling opening, which was still provided for the flexible container, is in the sealed container of FIG. 3 no longer visible. However, open to the top is a gap that leads into the interior 20a of the inwardly projecting bag 20 as an inner bag. Here, a moving device is provided as a flat paddle 40 which corresponds to a straight flat plate shape having an upper portion 41 and an inwardly projecting portion 42. Whose lower end 42e adjacent to the lower flat end of a seam, which bounds the inwardly projecting pocket 20 liquid-tight. The pages are essentially parallel.

The inwardly projecting bag 20 is made of a liquid-tight material, such as polyethylene, and so thin that it has sufficient freedom of movement to transmit a pivotal movement α α 'of the outer portion 41 to the inner portion 42, here as movement β β' , The introduced into the pocket 20 flat portion 42 forms with the pocket a moving unit, similar to that movement unit C of FIG. 2 , and allows a pivoting and thus a contribution of a movement to the beverage inside the flexible bag. This improves the cooling. The beverage is circulated and moves more often past the inner walls of the flexible bag to get deprived of energy, which is caused by the external cooling. It is not necessary to remove the outer packaging, it may also be present during the cooling process and in the inserted state.

The upwardly projecting opening 21, through which the planar movement element 40 is inserted, is limited in the example by a liquid-tight seam 70, which in FIG FIG. 4 can be seen more clearly with removed motion element 40.

It can be seen that a pivotal movement of the shaft 50 with the moving element 40 (these are rigidly connected to each other), can take place together about the axis 51 and exerts a movement on the beverage. The axis 51 is located near the seam 70, the load of the seam 70 is thus well and severely limited, so that it is not endangered. Here, too, the movement unit C carries with it the beverage constituents lying in the vicinity of the lower section 42 and distributes this movement to the total contents of the bag, to accelerate the cooling, to reduce the necessary energy and to rapidly supply a cooled beverage in the dispenser.

The state of an inwardly projecting pocket is in FIG. 4 shown for a bag, as in FIG. 3 Application finds. Here, the opening 15 is not yet closed, the outer outer packaging 9 is not present and the bag 10 is not yet filled. The pocket 20 with its planar extending interior 20a and its upwardly projecting opening 21 is prepared to receive the planar movement element 40 or 40 '. A bag edge bordering sealing seam 25, of vertical sections 25a and horizontal portion 25b is liquid-tight and of a sufficient width, for example, 1 mm to 5 mm. The inner pocket 20 thus formed is not a pocket, it is designed from the outset in the interior 10 a projecting. At the top, a gap-shaped opening 21 is circumferentially bounded by a sealing, liquid-tight sealed seam 70. The bag shape after FIG. 4 Can also be made detached without the outer packaging and is separately relevant. Its edge-side shape does not necessarily have to be a sealed seam, but can also be formed from an integrally formed bag, which is provided only in the region of the inner pocket with sealing seam 70, whereby a welded inner bag is formed.

FIG. 5 shows a detail as a third embodiment. This can be transferred to all the aforementioned embodiments, but especially those examples in which the inner pocket 20 or 20 'already protrudes into the interior and the interior 10a of the flexible container is filled with a beverage. It is from Advantage, when two flat plate sections 26a, 26b are provided by a longitudinal and transverse extension, which fit into the inner space 20a of the sealed by seam 25 "pocket 20". They have a slightly narrower width and about the length (depth) of the pocket or its interior 20a. In the upper opening 21 of this interior, the two flat plates are inserted, for example, from cardboard, cardboard or thin plastic strips. Between them, a gap is formed, which can be further increased by the fact that these plates have an inwardly directed arcuate shape 26c, the end face (at the edge of the respective disc tray) to each other to widen the opening 23 between the two plates.

In the thus formed preformed opening, which need not be burdened by fluid pressure and has been reduced to practically zero, the planar movement element 40 or 40 'can be inserted. It can then be added after insertion into the pivoting movement, to form a movement unit together with the plates and the paddle element liquid-tightly shielding inner bag 20 ".

The introduction of the plates 26a, 26c can already take place during the manufacturer's operation. This is favorable if it is a bag-in-box container type, in which liquid is already bottled as a drink at the manufacturer. The inserts of the plates but can also the bag shape FIG. 1 relate, at the liquid only at the place of issue, where the drink dispenser is filled.

The advantages of the described embodiments are the maintained hygiene and the prevention of precooling in separate cold rooms. Compared to beverages that do not have aseptic bags for packaging, the advantage lies especially in the hygiene sector, coupled with the possibility of achieving a rapid cooling down. A cleaning or a cleaning step can be omitted here due to the disposable packaging. This results in a much more flexible and faster availability of the cooled down beverage, especially for the system bag-in-box.

It is also possible to serve those installation locations which do not have refrigerators in which the supplied box containers are cooled down before being used in the dispenser.

The agitator blade (the moving paddle wing) can be turned off after cooling down. The drinking temperature thus achieved can be maintained by the normal cooling. It can then either be removed or simply left in the device without continuing to operate it.

A secondary effect of such a movement wing is to continuously circulate pulps or juices containing fruit pulp in order to evenly distribute the pulp throughout the fluid content. Here comes to the circulation and the movement added an additional effect, which is of course also coupled with a further improved cooling.

In the FIGS. 6 and 7 are shown sections of flexible containers. FIG. 6 basically recalls training FIG. 1 , wherein the filling opening 15 is provided and an edge-side seam 76 defines the container shape. Shown is a section in the direction of the filling opening and through the outer pocket, which is bounded by a sealed seam 76a. The folded pocket bounded by this seam 76a runs parallel to the seam 76, which limits the opening 15 to some extent, but defines the left edge of the container. The filling opening 15 is itself bounded by the sealing seam 75a, in the transition to the main bag. The view from above related to the FIG. 6 is in the FIG. 6a represented here as a horizontal section at the level of the sealing seam 75a.

An alternative embodiment with a vertical orientation of the slip pocket bounded by the seal 76b is shown FIG. 7 , Here, the side seal seams 76 ', 76 "are shown to be perpendicular to the extension of the slip pocket, as opposed to the parallel orientation of the seal seam 76 and the slip pocket 20' of FIG FIG. 6 ,
