Description

The present invention relates to a beverage dispensing system for rapid contact cooling of a beverage container and to a corresponding method of rapid contact cooling of a beverage container by using a beverage dispensing system.

Prior art

Beverage distribution systems are used in many beverage establishments, such as beer from a barrel. Such beverage distribution systems are used mainly in professional establishments, such as bars or restaurants, but their use is also growing by private consumers, for example, in private homes. For many beverage dispensing systems, for example, such as PgaidMMa81eg ™, manufactured by the applicant company, the beverage is typically bottled in plastic or metal containers or kegs. The beverage container is usually arranged vertically, i.e. the opening of the container faces upwards and the beverage flows out of the container of the beverage through an ascending tube. The beverage is usually squeezed out of the beverage container to the crane head by the pressure of a flowable agent, as a rule, by compressed gas. To avoid direct contact of the compressed flowable agent with the beverage, a compressible beverage container may be used. The use of compressible beverage containers, usually containing a beverage not yet saturated with carbon dioxide, is well known to those skilled in the art of dispensing beverages. When using a compressible beverage container, the compressed flowable agent acts from the outside of the beverage container, reduces the volume of the container and thereby squeezes the beverage out of the beverage container. In the case of a rigid container, the upright position and the ascending tube do not create problems, however, when using compressible beverage containers, there is a risk that the beverage container may be pressed into the ascending tube during the dispensing process. If the beverage container is pressed into the ascending tube, the ascending tube may be destroyed or clogged during the dispensing process, with the result that part of the drink will remain in the drink container. This residue of the beverage will be lost, since the beverage container must then be disposed of and replaced. Further, under the influence of the ascending tube, the walls of the beverage container may be broken. Such breakthroughs can lead to the leakage of a beverage into a beverage distribution system, the release of a compressed, flowable agent, and sometimes an explosion. Thus, ascending tubes, in the case of compressible beverage containers, are a problem.

The problem associated with the ascending tubes can be solved if the beverage container is positioned upside down, i.e. so that the opening of the container is facing down. If the beverage container is positioned upside down in the beverage distribution system, the ascending tube can be excluded. This eliminates the risk that some beverage residue will remain in the beverage container, since the beverage container can be compressed completely without blocking the opening of the container.

Compressible beverage containers used in beverage dispensing are usually made by blow molding single-part preformed blanks. The shape of the beverage container is largely determined by the geometry of the mold. As a rule, the beverage container has a cylindrical shape, and all corners are usually rounded, for example, so as to obtain a substantially circular cross section. Such containers are described, for example, in EOS 2004/099060, registered in the name of the applicant company and disclosing the method of dispensing a drink from a compressible container by using increased pressure.

For the most part, beverages intended for distribution using a distribution system for beverages of the type described above should be served chilled. Examples of such beverages include various beers, soft drinks and various colas. The aroma of such drinks largely depends on the temperature of the drink. For example, the taste of many beers is most pleasant when beer is served at a temperature of about 7 ° C. In addition, many beverages, including most beers, should be stored in the cold to stay fresh for a long time, for example for one day, at least when the container was already open and some air got into it. For example, beer will deteriorate very quickly if it is stored at room temperature, but if it is stored at a temperature of about 7 ° C, it can last for more than 50 days.

Therefore, in both professional and private beverage distribution systems, including the OgandSchMaCheg ™ system mentioned above. the beverage container is stored in a cooled chamber with increased pressure so that the beverage remains fresh and carbonated for a long time, for example, for at least 50 days. A beverage dispensing system comprising a refrigerating chamber is known from UO 2007/019853, registered in the name of the applicant company of the present invention and disclosing a beverage dispensing assembly including a refrigerated pressure chamber. The cooling effect is enhanced by fans, creating an additional cooling effect from forced convection. Document \ PP 02/30807 discloses a juice distribution unit containing a thermoelectric device. When using a cooled chamber of the type described above, the container with the beverage and the beverage in it are in an air volume that is constantly maintained at an appropriate low temperature. A beverage dispensing system may include a thermostat to account for fluctuations in outside temperature to maintain a constant low temperature in the chamber and beverage. In document νθ 2006/103566, the dispensing line is cooled by a separate cooling system to achieve cooling of the beverage to be dispensed. The disadvantage of such a system is that there may be insufficient cooling in the case of dispensing a drink with a high flow rate.

Since in most beverages the air promotes the proliferation of bacteria, the aforementioned beverage containers are substantially airtight. When using the aforementioned beverage containers as storage containers for pasteurized beverages, it is usually not necessary to keep the beverage container cold until the beverage comes in contact with air that occurs when the container is opened with the beverage. Therefore, such beverage containers are supplied to the customer at room temperature and must be cooled from room temperature to an appropriate dispensing temperature of approximately 7 ° C.

The problem with the delivery of the beverage container at room temperature is that when the beverage container is empty and a new beverage container needs to be installed, this new beverage container that has room temperature must be cooled to a temperature of about 7 ° C before you can resume distribution. Most gases, in particular air, are usually considered to be heat insulators and have significantly lower thermal conductivity than most liquids and solids, in particular metals. The main component of the beverage is water, which has a high thermal conductivity. Therefore, cooling a beverage contained in a container with a beverage originally stored at room temperature to an optimal distribution temperature of about 7 ° C can take up to 24 hours. Using forced convection, for example, generated by a fan, can slightly reduce the time required for cooling. Thus, an empty beverage dispensing system may be useless for 24 hours, which it needs for the beverage in the new beverage container to reach the proper dispensing temperature.

In many large professional beverage distribution establishments, this problem can be solved by isolating separate refrigerated storage rooms in which beverage containers can be stored at a temperature close to the distribution temperature. However, such refrigerated storage rooms consume a lot of energy, and the space in them, generally speaking, is considered expensive, so it would be preferable to be able to store relatively large containers with a drink outside the refrigerated storage room before they are installed in the beverage distribution system. In establishments that do not have a refrigerated storage room, several beverage dispensing systems can be installed in parallel, so that during the operation of one beverage dispensing system, the others can be cooled. This solution is practically inconvenient and, moreover, very expensive. Private users rarely have a refrigerated storage room or the ability to use parallel beverage dispensing systems, so they are usually forced to interrupt the distribution of beverages after emptying the container. Further, at any spontaneously organized public event or reception, for a long time, the cooling of a beverage delivered in a container with a beverage will cause a delay. Therefore, there is a need for technologies for rapid cooling of the beverage stored in the distribution system of beverages.

In the past, both professional and private consumers achieved cheap and effective rapid cooling of beverage containers by storing beverage containers in a tub of water and ice. Since ice water, respectively, liquid and solid, has a higher thermal conductivity than air, which is a gas, the beverage container cooled faster than, for example, using a cooler with a cooled chamber. Direct contact of the cold surface of a solid or liquid and the container with a drink provides much faster heat transfer than that possible through air. This principle of cooling is known as contact cooling. In some beverage dispensing systems, ice water is used to cool the beverage, for example, in the systems described in I8 2116622 and I8 2009/0044561. The drawbacks of using ice for cooling inside a beverage dispensing system are that when the ice melts, the temperature rises, and that when you melt ice, a lot of liquid water forms, which you have to dispose of.

Thus, the objective of the present invention is to propose technologies for rapid cooling of a beverage container without the above disadvantages.

Summary of Invention

According to the first aspect of the invention, the problem of the above need and the above task — along with many other problems and tasks that will be clear from the detailed description below — are solved by a beverage dispensing system with a compressible beverage container, the container in an uncompressed state having an upper wall the container opening, the opposing bottom wall and the cylindrical wall connecting the top and bottom walls, while the beverage distribution system includes a housing, granichivayuschy internal space extending from the opening to cover the rear end wall remote from the opening cover, wherein it is an internal space adapted to receive a beverage container;

a dispensing device having a dispensing handle for controlling the dispensing tap, the dispensing device communicating with the interior for receiving a dispensing line extending from the outlet of the beverage container to the dispensing tap;

a pumping device to increase the pressure in the inner space to a pressure greater than the pressure in the surrounding environment, so that the beverage is squeezed out of the beverage container to the outlet of the container when the filling tap opens with a filling handle; and a cooling element placed in the inner space and containing a contact cooling surface, the curvature of which corresponds to the curvature of the cylindrical wall, bottom wall and / or upper wall of the container with the drink, the contact cooling surface being close and in contact with the cylindrical wall, bottom wall and / or upper wall at least 10%, preferably 20% or more than 50, 70, 90 or even 100% of the wall surface when the beverage container is placed in an uncompressed state in the internal space consistency of.

The applicant company found that, oddly enough, a cooling element with a contact cooling surface that is close to and in contact with at least 10% of the container wall surface significantly increases the cooling efficiency and reduces the time required to cool the beverage inside the beverage container compared to with only convection air cooling. As is known to all specialists, during convection air cooling of a beverage container, the cooling effect is achieved due to natural convection in the air space between the cooling devices located in the inner space and the walls of the beverage container. The efficiency of such cooling depends on the heat transfer or, in other words, on the heat flow between the beverage and the cooling element. The heat flux from the beverage in the beverage container to the cooling element can be calculated by the following formula:

where H is the heat flux; K - coefficient of thermal conductivity;

And - the area of contact between the drink and the contact cooling surface;

T n - temperature of the drink;

T with - temperature of the cooling element and

B is the distance between the cooling element and the beverage.

The coefficient of thermal conductivity is a characteristic of the material, and its values are different for different materials in the path of the heat flow of cooling, i.e. for the cooling element, the walls of the beverage container and the beverage itself. Therefore, it is recommended to use materials with high thermal conductivity, especially for the contact cooling surface and the cooling element, which can be made of a material with high thermal conductivity. Due to the very low thermal conductivity of air, air convection cooling is a very slow process, and cooling a container with a beverage of normal size and the beverage contained in it to an acceptable dispensing temperature may take 24 hours or more. When the contact cooling surface is in contact with at least 10% of the surface of the container containing the beverage, cooling is achieved with direct heat transfer between the cooling element and the container with the beverage. Cooling efficiency with direct heat transfer is much higher than with convection air cooling.

The distance between the cooling element and the beverage should be as small as possible, for which it is preferable to make the walls of the beverage container as thin as possible. There is, however, a limit to reducing the wall thickness of the beverage container while maintaining the structural stability of the beverage container. The temperature of the cooling element should be as low as possible, since the heat flow also depends on the temperature difference between the beverage and the cooling element. However, care should be taken to avoid the formation of ice crystals in the drink. The ice crystals in the drink can spoil the taste of the drink and can clog the container hole, filling line and / or dispenser, which can block further dispensing of drinks. Thus, there is a lower temperature limit of the cooling element, approximately equal to 0 ° C or, possibly,

- 3 022684 at a few degrees centigrade scale below 0 ° C - depending on the alcohol content in the drink.

The amount of heat energy taken from the drink (i.e. the heat flux from the drink) is directly proportional to the contact area between the drink and the cooling element, therefore, given the relative constancy of most other formula parameters, it is important to have a large cooling contact surface between the cooling element and the container a drink. Therefore, the contact cooling surface must have a shape adapted to the curvature of the walls of the container with the drink in order to achieve the largest possible contact area. The contact cooling surface is preferably in contact with the cylindrical wall of the beverage container, however it may also contact the bottom wall and / or the upper wall, excluding that part of the upper wall in which the container outlet is located. The observations also showed that the cooling element and the contact cooling surface can be broken up into several cooling elements with several cooling contact surfaces, better adjacent to the walls of the beverage container.

The beverage container must be of a compressible type, which means that the walls of the beverage container must be relatively thin and made of compressible material. When the beverage container is filled with a beverage, it is in an uncompressed state. Usually, a container with a drink in an uncompressed state contains 10 liters of drink, however, containers from 5 to 70 liters are also possible. The beverage container may be made of a metal with high thermal conductivity, however, it is preferable to use plastics or similar polymeric materials due to their flexibility and for environmental reasons, since these materials are easily disposed of by incineration. It should be noted that since the walls of the beverage container are thin, the thermal conductivity of the material chosen for the beverage container does not have a very large effect on the heat flux and, therefore, on the cooling efficiency.

Compressible beverage containers are typically made by blow molding plastic preformed blanks and then filled with beverage. The containers produced in the process of such casting have a bottom, an upper wall and a cylindrical wall between them. The bottom can be molded as a circular disc so that the beverage container can stand upright without additional support. The bottom preferably smoothly passes into the cylindrical wall, and the diameter of the cylinder, as a rule, is substantially constant along the entire length from the bottom of the beverage container to its top. The upper wall of the beverage container preferably has a convex shape and includes a centrally located flange with the outlet of the container, which should be sealed immediately after filling the container with a drink. A filling tap can be part of a dispensing line, part of a dispenser, or a separate unit.

The beverage container is placed in the inner space of the beverage distribution system housing by opening the opening lid and sliding the beverage container through the opening thus created. After closing the opening cover, the pressure in the internal space can be increased by means of a pumping device. A filling line connects the filling tap to the outlet of the container. Manipulation of the filling handle results in pushing the beverage out of the beverage container under the effect of pressure in the internal space. As the container is compressed, the beverage flows out of the beverage container, flows through the bottling line, and from the filling tap through the beverage outlet opening of the filling tap, exiting the beverage distribution system.

Any contact cooling surface that is not in contact with the wall of the beverage container can be considered as waste, since the cooling efficiency through the air, as discussed above, is limited. The advantage of the currently preferred embodiment of the present invention is that the beverage container is in contact with a large portion of the contact cooling surface.

In one embodiment, the further development of the system according to the first aspect of the present invention during the distribution of the beverage from the beverage container, the contact cooling surface continues to contact at least 10%, preferably 20% or more than 50% or even 100% of the cylindrical wall the bottom wall and / or the top wall of the beverage container until at least 30%, preferably 50% or more, for example 70% or even 90% of the beverage contained in the beverage container is distributed. When the beverage container is subjected to pressure and begins to shrink, it may happen that the contact cooling surface loses contact with the walls of the beverage container, with the result that the cooling efficiency will decrease significantly. Due to the effect of gravity on the beverage, the compression of the beverage container begins at the top and continues downwards if the displacement of the beverage container is not limited. Therefore, it is preferable that the contact cooling surface is located under the beverage container so that the beverage container is compressed in the direction of the contact cooling surface under the action of gravity and pressure. Alternatively, the cooling element and / or the beverage container may be spring loaded to create a force that holds the beverage container against each other and the contact cooling surface to maintain contact even after the beverage container is substantially compressed. It should be noted further that the lower location

- 4 022684 contact cooling surface reduces the likelihood of an air bubble, resulting from the location of the head part of the container with a drink at the contact cooling surface. Such an air bubble greatly reduces the cooling efficiency.

In one embodiment of the further development of the system according to the first aspect of the present invention, the contact cooling surface of the beverage dispensing system is able to reduce the average temperature of 10 liters of beverage, initially having room temperature and stored in the beverage container at least 10 ° C, preferably at least 15 ° C during no more than 3 hours, preferably no more than 2 hours, preferably no more than 1 hour. The applicant company conducted laboratory tests confirming that this preferred option Implementation of the present invention according to its first feature is capable of cooling 10 liters of beverage from a storage temperature of 22 ° C to a preferred dispensing temperature, for example, 7 ° C in less than 3 hours.

In one embodiment of the further development of the system according to the first aspect of the present invention, the time required to cool the beverage, which is stored in an uncompressed beverage container, is reduced from room temperature to dispensing temperature to at least 1/3, preferably at least 1/4 of the time. required to cool a beverage that has been stored in an uncompressed beverage container from room temperature to dispensing temperature when the contact cooling surface is in contact with 0% of the contact surface. ynera with a drink. The applicant has found that cooling a beverage that has been preserved in a beverage container to the proper dispensing temperature requires significantly less time when using contact cooling instead of convection air cooling.

In one embodiment of the further development of the system according to the first aspect of the present invention, the contact cooling surface went in the longitudinal direction determined by the measurement between the opening lid and the end, and in the transverse direction defined by the arc corresponding to the curvature of the cylindrical wall of the beverage container, 90 to 180 °, preferably from 120 to 160 °. Preferably, the beverage container is placed in the cage, which is a cooling element, which makes it possible to form a very large contact cooling surface partially covering the cylindrical wall of the beverage container and at the same time making it easy to remove the beverage container.

In one embodiment of the further development of the system according to the first aspect of the present invention, the beverage container is pressed against a contact cooling surface using, for example, a spring or inflatable pillow or, alternatively, a contact cooling surface that has a slightly smaller radius than the beverage container. When the spring-loaded mounting of the cooling element and / or the beverage container to create a force that presses the beverage container and the contact cooling surface against each other, the cooling efficiency can be improved, since in this case the beverage container is pressed against the cooling surface. As a result of pressing the beverage container and the cooling surface against each other, the contact area between them may increase, since those small air bubbles that would otherwise be between the contact cooling surface and the beverage container will be eliminated. It is clear that the spring-mounted installation can be replaced by other similar means, such as an air bag, etc. Further, the contact cooling surface may have a slightly smaller radius than the beverage container, so that the beverage container turns out to be slightly compressed; this is achieved by increasing the contact area.

In one embodiment of the further development of the system according to the first aspect of the present invention, when the beverage container is placed in the inner space, the cylindrical wall of the beverage container carries the substantially full weight of the beverage container. Preferably, the entire weight of the beverage container is transferred to the contact cooling surface in order to ensure that the beverage container is pressed against the contact cooling surface. The force of such a clamp can even select all the gaps between the contact cooling surface and the wall of the beverage container and eliminate all the air pockets that may be between them.

In one embodiment, the further development of the system according to the first features of the present invention, the opening cover is located above the end or with a horizontal centering relative to the end. The opening lid is preferably located above the end or horizontally centered with respect to the end, in order to provide a simple and using gravity to introduce the beverage container into the inner space.

In one embodiment, the further development of the system according to the first aspect of the present invention, when the beverage container is placed in the inner space, the bottom wall of the beverage container is located at the opening lid, and the upper wall is located at the end wall, the inner space contains a connector located at the end and connecting to the outlet of the container. In order to avoid the use of the ascending tube, the opening of the container is preferably located near the end and at a distance from the opening cover.

In one embodiment, the further development of the system according to the first features of the present invention, the longitudinal measurement of the contact cooling surface determines the slope relative to the horizontal plane in the range from 5 to 85 °, preferably from 10 to 80 °, more preferably from 20 to 70 °, for example 25, 30, 35, 40, 45, 50, 55, 60 and 65 °. The contact cooling surface preferably defines a slope so that the contact cooling surface can have a large area and, at the same time, so that the contact cooling surface can occupy the lower position and at the same time that the beverage outlet can be located at the bottom.

In one embodiment of the further development of the system according to the first aspect of the present invention, the housing further includes a front wall, this front wall can be rotated around an axis to an open position, in which access is allowed outside to the inner space, and can be rotated to a closed position, in where the interior space is not accessible from the outside; in this case, optionally, a filling device can be mounted on the front wall. This swiveling front wall allows easy installation of the distribution line.

In one embodiment of the further development of the system according to the first aspect of the present invention, the beverage dispensing system further includes a separate beer column located outside the body, preferably in front of or next to the body, and a dispenser is placed in this beer column. Alternatively, a separate beer column can be used. Since in this embodiment no cooling is required in the beer column, the beer column can be made very thin.

In one embodiment of the further development of the system according to the first aspect of the present invention, the cooling element includes a Peltier element or, alternatively, the cooling element is connected to the refrigeration device with cooling pipes, and the refrigeration device includes a compressor, a refrigerant and a heat sink, with the heat sink outside the internal space.

The beverage container 28 includes a connecting flange 38 facing the base plate 12 when the beverage container 28 is installed in the inner space 32. The filling line 40 extends from the connecting flange 38 to a filling tap (not shown) located in the tap head 22. The combined cooling and pumping device 34 provides cooling for the cooling element 30 as well as the pumping of the internal space 32. The combined cooling and pumping device 34 can optionally cool the internal space 32, however its space 32 can also be cooled by a cooling element 30. Further, instead of the combined cooling and pumping device 34, a separate cooling device and a separate pumping device can be used.

FIG. 3A shows a first embodiment of a cooling element 30 ′ according to the present invention. The beverage container 28 includes the bottom of the beverage container 42 opposite the connecting flange 38. The beverage container 28 further includes a cylindrical container wall 44 connecting the bottom 42 of the beverage container and the connecting flange 38. The cooling element 30 'has a contact cooling surface 46 which has a curvature corresponding to the curvature of the cylindrical wall 44 of the beverage container 28, and is adapted to receive a cylindrical wall 44 with a tight fit of a portion of the cylindrical wall 44 of the container. The cooling element 30 is preferably made of metal, for example, from aluminum or any similar material having a high thermal conductivity. The cooling element 30 'according to this embodiment of the invention includes a Peltier element electrically connected to the combined device 34' for cooling and pumping with electric wires 36. The combined device 34 'for cooling and pumping energizes the Peltier element, producing a cooling effect.

FIG. 3B shows a further embodiment of a cooling element 30 according to the present invention. The cooling element 30 has a shape corresponding to the cooling element 30 'of FIG. 3A, but instead of the Peltier element, the cooling element 30 includes a cooling inlet 48. The combined cooling and pumping device 34 includes a cooling pipe 36, which is inserted into the cooling inlet 48 of the cooling element 30 to supply refrigerant to the cooling element 30.

The combined cooling and pumping unit 34, therefore, includes a compressor (not shown) for cooling the refrigerant.

FIG. 3C shows a further embodiment of a cooling element 30 ′. The cooling element 30 'of FIG. 3C is similar to the cooling element 30 of FIG. 3B, but instead of inserting through the cooling inlet 48, the cooling pipe 36 is fixedly connected to the cooling element 30 and forms a grid or a grid in the cooling element 30 for optimal distribution of the refrigerant over the contact cooling surface 46 of the cooling element 30 '.

FIG. 4A is a side view of a beverage dispensing system 10. As can be seen, the body portion 14 rises upward from the support plate 12, passes, further, above the drip pan 20, and forms an angle of about 45 ° with the support plate 12.

FIG. 4B is shown in a side view of the beverage dispensing system 10 in a position where the front body part 18 is lowered to the support plate 12. In the normal position, when the beverage dispensing system 10 is running, the front body part 18 is vertical, as is the body part 14. When in the system When dispensing beverages, a new beverage container (not shown here) should be installed; the front body part 18 can be rotated towards the support plate 12 in a substantially horizontal position, as indicated by the arrow. When the front body part 18 is rotated, the crane head 22 is located next to the support plate 12.

FIG. 4C is shown in a side view of the beverage dispensing system 10 after the front body part 18 is rotated to a horizontal position. After the front housing part 18 is rotated to the support plate 12, it becomes possible to remove the cover 16. The cover 16 is fastened with a bayonet connection, and to remove the cover 16, it is rotated about 1/4 of a turn and lifted upwards. The cover 16 forms an internal upper cavity 50, bounded by the body part 14.

FIG. 4Ό shows in side view the system 10 for dispensing beverages in a position where a new beverage container 28 is inserted into the body portion 14. After removing the cover 16, access to the inner space is opened (not shown here). The beverage container 28 should be fitted with a connecting flange 38 to the support plate 12 and should make an angle of about 45 ° with the support plate 12.

FIG. 4E is shown in a side view of a beverage dispensing system 10 in a position where the beverage container 28 is inserted into the inner space (not shown here).

FIG. 5A, a beverage dispensing system 10 is shown including a body portion 14 without a lid 16. As discussed above, the body portion 14 extends toward the front of the support plate 12 above the drip pan 20 at an angle of about 45 °. Here, the front body part 18 is lowered to its substantially horizontal position and forms the optional support block 56. The beverage container 28 is removed from the package 54 and mounted with an inclination of about 45 ° to the horizontal plane in a stable first mounting position. The beverage container 28 includes the bottom 42 of the beverage container; this bottom is convex, so that the beverage container 28 can easily be rotated to the first mounting position. In this embodiment, the bottom 42 of the beverage container rests on the support block 56 and on the front body portion 18, however, in an alternative embodiment, the bottom 42 of the beverage container may rest on the front body portion 18, the support plate 12 or on any substantially horizontal plane, depending on the size of the beverage container and the system 10 distribution of drinks. The use of the support block 56 may be preferable since it prevents the bottom 42 of the beverage container from slipping.

The body portion 14 includes an upwardly facing rim 62, through which the inner space 32 of the body portion 14 is accessible. The rim 62 includes a contact surface 60 facing the drip tray 20. The beverage container 28 further includes a rounded top 58 of the beverage container having a centrally located connecting flange 38. This connecting flange 38 includes an opening of a container for discharging a beverage contained in a beverage container 28. The top 58 of the beverage container and the connecting flange 38 are pressed against the contact surface 60 of the rim 62 of the body portion 14. The contact surface 60 is curved to ensure a stable position of the beverage container 28 and prevent the beverage container 28 from moving both in the direction of the body portion 14 and in lateral directions.

The beverage container 28 is a container of a compressible type and may have a typical capacity of about 10 liters, providing approximately 20 servings of beverage before the need to install a new container 28 with a beverage. A typical height of the beverage container 28 for the beverage dispensing system 10 is from 0.25 to 0.5 m, preferably 0.35 m.

FIG. 5B illustrates a beverage dispensing system 10 in the process of ergonomically fitting a beverage container 28. By raising its bottom 42, the beverage container 28 can be rotated with rotation around the contact surface 60 to a raised position. Preferably, this rise is carried out by the user, whether it is a private user or a professional operator of the beverage distribution system, for example, a bartender or a barmaid. Alternatively, to avoid injury to personnel when using large and heavy beverage containers, a lifting device, such as a crane, may be used to lift the bottom 42 of the beverage container 28. In another alternative embodiment, when the beverage container 28 is in contact with the appropriately shaped supporting block 56 of the front hull 18, the bottom 42 of the beverage container can be rotated by simply turning the front hull 18 upward to its vertical position. During the rotation operation, the contact surface 60 remains in contact with the top 58 of the beverage container. The contact surface 60 simplifies the rotational movement of the container 28 with the drink. The curvature of the contact surface 60 and the corresponding curvature of the top 58 of the beverage container and the connecting flange 38 of the beverage container 28 prevent any lateral movement of the beverage container 28. The connecting flange 38 is used to grip the contact surface 60 of the rim 62 over a large angular portion of the contact surface 60 in order to avoid sliding the container 28 with the drink.

When the bottom 42 of the beverage container rises further and the beverage container 28 rotates stronger, the contact surface 60 of the rim 62 assumes the bulk of the weight of the beverage container 28. In this case, the beverage container 28 rests primarily on top 58 of the beverage container and, possibly, on the connecting flange 38, if this is required for a steady turn. Accordingly, the top 58 of the beverage container and the connecting flange 38 should be made sufficiently rigid to withstand the weight acting on them. In order to avoid the risk of any breakage, the above two parts can preferably be reinforced, for example, by using a double or double layer container. The double-layered container contains an inner compressible beverage container protected by an outer rigid container. The use of such a double-layer container in some embodiments makes the lid 16 unnecessary, since in this case the pressurized flowable agent is enclosed in the space between the outer container and the inner beverage bag.

The destruction of the connecting flange 38 or the destruction of the top 58 of the beverage container in the intermediate position shown in FIG. 5B may result in the uncontrolled fall of the beverage container 28 to the ground, which may result in equipment damage or injury to the user.

The beverage dispensing system 10 preferably includes an element of the piercer 64 at the end of the bottling line 40. The filling line 40 and the element of the piercer 64 are secured in the housing at a distance from the rim 62 and can be replaced as needed. The outlet of the container in the connecting flange 38 of the beverage container 28 includes a corresponding penetrating membrane (not shown). Alternatively, the beverage container 28 can be supplied with a filling line 40 and a filling tap (not shown) already connected to the outlet of the container in the connecting flange 38.

FIG. 5C shows a beverage dispensing system 10 when the beverage container 28 is installed in the inner space 32. As the beverage container 28 continues to rotate, ensuring, if necessary, the horizontal moving force is directed to the beverage container 28 in the direction of the rim 62, the rounded top 58 the beverage container begins to slide along the contact surface 60 of the rim 62 and slides into the inner space 32. For safety reasons, the user should avoid all contact with the rim 62 syst Beverage dispensers, riding the drink container 58 and the connecting flange 38, when the drink container 28 may begin to slide into the interior space 32, since such contact may cause injury to the user.

It should be noted that the beverage container 28 does not have to fit perfectly into the rim 62 of the beverage distribution system. It is enough that the connecting flange 38 enters the rim 62, since after the start of sliding the position of the beverage container 28 will be corrected, and the beverage container 28 will continue to spontaneously move into the internal space 32 of the beverage distribution system 10. The beverage container 28 is guided by the curvature of the contact surface 60, and when the beverage container 28 enters the inner space 32, the beverage container 28 is guided to the correct position by the rim 62 and top 58 of the beverage container 28. Thus, even with some input error, the beverage container 28 may enter the inner space 32. The inner walls of the body part 14, which delimit the inner space 32, and the contact cooling surface 46 will orient the beverage container 28 so that the connecting flange 38 will face the piercer element 64.

In the inner space 32, the beverage container 28 slides over the concave surface 46 '. This concave surface 46 'should have a concavity curvature corresponding to the curvature of the cylindrical wall 44 of the container. The concave surface 46 'is preferably identical to the above-described concave contact cooling surface 46, however, in some embodiments, a separate contact cooling surface 46' may be used or the contact cooling surface may be part of the inner wall of the body portion 14.

Having reached the support position at the bottom end of the inner space 32, remote from the rim 62, the connecting flange 38 of the beverage container 28 is moisture-tightly connected to the element of the piercer 64 of the filling line 40 in the inner space 32. At the same time, the beverage container 28 will protrude slightly from the inner space 32. After the beverage container 28 has reached the support position, the lid 16 can be put back in place and hermetically fastened to the rim 62 of the beverage dispensing system 10. This completes the installation procedure, and after pumping the internal space 32, the beverage can be dispensed from the system 10 for dispensing beverages by turning the filling handle 24.

In order to avoid damage to the beverage container 28 upon impact when the position of the support is reached at the bottom end of the internal space 32, a shock absorber may be provided in the internal space 32, for example, a pillow made of foam, natural or synthetic rubber, to prevent damage or even destruction. or flattening the beverage container 28.

After emptying the beverage container 28 in the inner space 32, the pressure is released and the cover 16 is removed. This allows you to remove and replace the container 28 with a drink. As a rule, the container 28 with a drink is completely compressed, so it is easy to remove and dispose of it.

FIG. 6A shows an alternative embodiment of an ergonomic operation according to the present invention; In this embodiment, the beverage container 28 remains in the package 54 during part of the installation procedure. The package 54 includes a package bottom 54 ', an opening top 54 of the package and four pairwise parallel side walls that are not assigned position numbers, but which connect the bottom 54' and the top 54 packs. The top 54 of the package includes flaps 54 ', which serve to seal and close the package 54 during storage and transportation.

The beverage dispensing system 10 shown in FIG. 6A includes a body portion 14 with a rim 62 ', similar to that presented in the above-described embodiments. The rim 62 'differs from the rims described above in that the contact surface 60' of the rim 62 'defines the plane of the outer contact surface, unlike the rounded contact surface in the previous embodiments of the dispensing unit shown in FIG. 5A-5C. The contact surface 60 'corresponds to the top 54 of the package. The package 54 may thus be located in a rotated position, in which the top 54 of the package rests on the contact surface 60 '. The bottom 54 'of the package remains in contact with the front body part 18 or, alternatively, with the support plate 12.

FIG. 6B shows an alternative embodiment of an ergonomic operation according to the present invention; in this embodiment, the bottom 54 'of the package is lifted and the package 54 together with the beverage container 28 is turned around the contact surface 60'. The beverage container 28 may slide from the package 54 to the rim 62 'and further into the inner space 32 of the body part 14, while

- 10 022684, the package 54 remains in a raised position, as shown in FIG. 6a.

FIG. 6C shows an alternative embodiment of an ergonomic operation according to the present invention when the beverage container 28 is already installed. After the beverage container 28 has reached its final position, the package 54 can be removed and the lid 16 is put in place.

FIG. 7A illustrates the installation of a beverage container 28 in a beverage dispensing system 10. In the first step, the beverage container 28 is introduced through the rim 62 into the inner space 32, and the connecting flange 38 is connected to a punch element (not shown). In the second step, the lid 16 is attached to the body portion 14, while the beverage container 28 rests on the contact cooling surface 46 of the cooling element 30. In the third step, the front body portion 18 is rotated back to the vertical position, which makes beverage dispensing operations possible.

FIG. 7B shows beverage dispensing by turning the dispensing handle 24 of the beverage dispensing system 10. After the beverage container 28 is installed in the beverage dispensing system 10 and the internal space 32 is pumped, the beverage dispensing system 10 is ready for operation. Turning the filling handle 24 from a substantially vertical position defining the non-dispensing position to a substantially horizontal position defining the beverage dispensing position opens the filling tap (not shown) in the tap head 22, and the beverage will be squeezed out of the beverage container 28 through the dispensing line 40, a dispensing valve and an outlet 26. The beverage is preferably collected in a beverage glass 52 located under the outlet 26.

The beverage container 28 is made by blow molding from a flexible polymer material, usually plastic, for example, polyethylene terephthalate or polypropylene. This beverage container 28 has a height of about 0.35 m and a diameter approximately equal to the height. When squeezing a beverage out of the beverage container 28, the pressure in the inner space 32 pushes the beverage outward, while at the same time flattening the beverage container into a compressed state, as shown. The figure shows a beverage container in a state where about 50% of the volume of the beverage is dispensed. The beverage container 28 is compressed, starting from the raised bottom 42 of the beverage container or from the cylindrical wall 44, and downward in the direction of the connecting flange 38. It should be noted that the surface of the beverage under the action of gravity always remains substantially horizontal and the beverage container 28 takes the shape corresponding to the surface of the drink. Due to local differences in the strength of the beverage container material during compression of the beverage container 28, a somewhat uneven surface may form, as shown in the figure.

The applicant company has determined that when the outlet of the connecting flange 38 is located below the rest of the beverage container 28, the force of gravity will help push the beverage out, and the ascending tube can be omitted. Further, in order to ensure the contact of the contact cooling surface 46 with the cylindrical wall 44 of the container even after dispensing a significant portion of the beverage, the contact cooling surface 46 should also be located as low as possible. In this embodiment, the contact cooling surface 46 is tilted at an angle of about 45 ° to the horizontal plane so that at least 50% of the beverage volume can be distributed without losing contact of the cylindrical wall 44 of the container with the contact cooling surface 46 and at the same time It was possible to distribute the drink down to the last portion, since the outlet of the container and the connecting flange 38 are located in the lower position. Further, it was found that the cooling element 30 and the contact cooling surface 46 can be slightly bent inward so that they rise inside to the top 58 of the beverage container for contact with a portion of the top 58 of the beverage container in the area near the junction of the top 58 of the beverage container into a cylindrical the container wall 44 in order to increase the contact cooling surface 46 and to properly perform the function of the locking wedge when the beverage container 28 slides into the body portion 14. However, the cooling element 30 does not must form a structure that interferes with the passage of the connecting flange 38, therefore the size of the connecting flange 38 puts a practical limit to the internal length of the cooling element 30.

FIG. 8A is a sectional side view of a further embodiment of a beverage dispensing system 10 ′. Compared with the previous embodiment, in the beverage dispensing system 10 ', there is no front body part including the tap head, and instead there is a separate beer column 66 including the tap head 22', the dispensing handle 24 'and the beverage outlet 26'. The tap head 22 'is located at the top of the beer column 66. This separate beer column 66 extends upward from the support plate 12 in front of the body portion 14'. The drip pan 20 'is located under the beverage outlet 26'. The figure shows the installation of a new beverage container 28 in the body part 14 and the subsequent installation of the lid 16 on the body part 14.

FIG. 8B is a sectional side view of a beverage dispensing system 10 ′, ready to dispense a beverage. Manipulation of the filling handle 24 'of the beer column 66 causes the beverage to flow out of the beverage outlet opening 26'. It was found that the beer column 66 can be located on a separate support plate at a certain distance from the body part 14, i.e. beer column 66 can be located on the bar, while the body part 14 is located under the bar

- 11 022684 resistant.

FIG. 9A is a sectional side view of another embodiment of the beverage dispensing system 10. The beverage dispensing system 10 includes a lid 16 comprising an auxiliary cooling element 68 having a shape adapted to fit tightly to the bottom 42 of the beverage container, and thereby providing additional cooling of the beverage container 28.

FIG. 9B is a sectional side view of a beverage dispensing system 10, ready to dispense a beverage. The auxiliary cooling element 68 is tightly pressed to the bottom 42 of the beverage container and thereby creates an additional contact cooling surface 70. It has been found that in some embodiments, the use of the auxiliary cooling element 68 can be sufficient, so that the cooling element 30 can be dispensed with.

FIG. 10A is a sectional side view of a beverage dispensing system 10 ′, which is an alternative embodiment of the previously presented beverage dispensing system 10, repeating most features of the beverage dispensing system 10 ′. As in the previously described embodiments, the body portion 14 'of the beverage dispensing system 10' forms a bend, but in this case its angle is about 90 °. The cooling element 30, located in the inner space 32 'of the body portion 14, is oriented substantially horizontally, i.e. parallel to the support plate 12 ', and forms a concave contact cooling surface 46'.

FIG. 10B is a sectional side view of a beverage dispensing system 10 ′, ready to dispense a beverage. The beverage container 28 should preferably be equipped with an ascending tube in order to reliably dispense the entire volume of the beverage. The advantage of this embodiment is that the cylindrical wall 44 of the container maintains substantial contact with the contact cooling surface 46 'until the beverage is completely extruded from the container 28 with the beverage. An optional air cushion 72 is provided in the inner space to extrude the beverage from the beverage container 28 and to achieve greater contact pressure between the cylindrical wall 44 of the container and the contact cooling surface 46 '. It was found that such an air cushion could be used for the same purpose in other embodiments, for example in the embodiment of FIG. 7

FIG. 11A is a sectional side view of a beverage dispensing system 10 ′, which is an alternative embodiment of the previously presented beverage dispensing system 10, repeating most features of the beverage dispensing system 10 ′. Unlike the previously described embodiments, the body portion 14 of the beverage dispensing system 10 ′ forms a straight upright body portion 14. The cooling element is absent, however, an auxiliary cooling element 68 is placed in the lid 16.

FIG. 11B is a sectional side view of a beverage dispensing system 10, ready to dispense a beverage. The cooling element 60 placed in the cover 16 is now oriented substantially horizontally, i.e. parallel to the support plate 12 ', and forms a concave contact cooling surface 70 in contact with the bottom 42 of the container with the drink. The advantage of this embodiment is that the connecting flange 38 of the beverage container 28 is low. The cooling element 60 may optionally be spring-loaded to the bottom 42 of the beverage container.

The beverages used in the embodiments of the present invention may be either carbonated or non-carbonated, and the beverage containers may be equipped with an ascending pipe — or the ascending pipe may be missing. However, in the currently preferred embodiment, the beverage is carbonated, and there is no ascending tube.

When placed inside the container, due to its flexibility, the beverage container may acquire a slightly elliptical shape due to the weight of the beverage, and when pressure rises in the internal space, the beverage container may slightly change its shape to a bit more spherical.
