Description

Device for dispensing beverages

The present invention relates to a device for dispensing beverages having a beverage bag being at least partially configured transparently and a container for receiving the beverage bag.

So-called bag-in-box beverage containers consist of a tube bag and a cardboard box enclosing the tube bag. The beverage bag or tube container is filled airlessly with a product ready for drinking or a concentrate. Such bag-in-box beverage containers usually comprise a beverage outlet which is configured integrally with the tube bag. A beverage outlet for such beverage bags is distributed, for example, under the trade name V-TOP® by the company Smurfit. Furthermore, it is known that such bag-in-box beverage containers may be received in beverage dispensers, so-called dispensers. Document DE 20 2006 Oil 691 teaches a receiving device for bag-in-box beverage containers, the device having a transparent receiving compartment. Here, the receiving compartment is configured such that a standardized bag-in-box beverage container with its cardboard outer packing is entirely received. Through the receiving compartment made of acrylic glass, the label of the outer packing of the bag-in-box beverage container can be clearly read.

It is a disadvantage of said beverage dispenser that the cardboard outer packing increases the required installation space for the bag-in-box beverage container. The cardboard packing is configured relatively stiff. For placing said stiff bag-in-box beverage container within the receiving compartment, the receiving compartment has to be freely accessible from the backside. Otherwise, it is not possible to pass the beverage outlet through the front wall. Such a filling from the backside is often awkward, particularly since the through opening is configured relatively small and the dispensers are often placed such that the backside thereof is not accessible.

Additionally known are electrically operated beverage dispenser, in which a beverage concentrate is pumped out of a bag-in-box storage container and subsequently diluted with water. For example, US 5,575,405 A discloses such a dispenser. Two different beverage concentrates are stored in two bag-in-box beverage containers. The concentrate is diluted with water and then dispensed to the user. It is a disadvantage of such beverage dispensers that they are relatively expensive and complex. Additionally, such dispensers are relatively voluminous and require a power supply. JP 2002 145398 A describes an auxiliary housing for receiving a beer container. The housing comprises a double wall structure and is configured as transparent body, the interior of which can be checked visually.

In contrast thereto, it is an object of the present invention to overcome the disadvantages of the state of the art and, particularly, to provide an improved and/or alternative and/or additional beverage dispenser.

Preferably, it is an object of the present invention to provide a device which shows the filling level thereof in a simple manner. Additionally, it is a preferred object of the present invention to provide a dispenser in which the beverage is protected against outer influences like heat, light, etc. It is a further preferred object to provide an economic and versatilely applicable beverage dispenser. Particularly preferably, the dispenser can be filled easily. It is a further aspect of the present disclosure to provide a dispenser for cooled beverages which can be operated without electric power supply.

The object is achieved by the features according to claim 1.

According to the technology disclosed here, the device for dispensing beverages or the dispenser comprises a container for receiving a beverage bag or a beverage container. Advantageously, an at least partially at least partially transparently configured beverage bag or beverage container is received in the container. Particularly preferably, the container is suitable to receive a bag-in-box container without its enclosing cardboard box. The container comprises a bottom region and a peripheral region. The peripheral region comprises an outer wall and an inner wall. The outer wall and the inner wall are at least partially configured spaced apart from each other. Preferably, the outer wall and/or the inner wall comprise on at least one of their surface a micro-topography and/or a macro-topography. The peripheral wall or the peripheral region of the container is at least partially translucent. This means, the peripheral region is configured at least partially not entirely transparently but only partially translucently. In other words, the peripheral region is neither entirely transparent nor opaque. Rather, the peripheral region should spatter visible light to a visually recognizable extent and should be configured substantially translucently, murkily or opaquely. Particularly preferably, the peripheral region comprises at least a minimal translucence at which a non-transparent or non-colourless beverage in an at least partially transparent beverage bag portion can at least dimly be recognized. Thus, a user can advantageously recognize the filling level of the container from outside of the outer wall of the container. The beverages can be any non-transparent or non-colourless beverages like, for example, coffee, juices, milk, etc. By means of the translucent container it is possible to make the at least partially transparent beverage bag at least portionwise unrecognizable when the beverage bag without its outer packing is received in the container.

Advantageously, it is thus also possible to inhibit or reduce the negative influence of light on the beverage without having to adopt complicated mechanisms for checking the filling level.

Advantageously, the peripheral region has a maximal translucence at which the user does not recognize the at least partially translucent beverage bag portion. A dispenser or a container having such a maximal translucence in its peripheral region gives the user the impression that a freshly prepared coloured beverage, for example a freshly prepared juice, is delivered. Additionally, such a translucent structure is an attractive design.

Preferably, the micro-topography is a mattfinished surface of the peripheral region. The surface of the container may be a ground, sandblasted and/or eroded surface, for example a surface with a roughness of 18 to 36 micrometers, preferably of 24 to 34 micrometers, and particularly preferably of 30 to 33 micrometers.

Preferably, the surface is an eroded structure 18 to 36, preferably 24 to 34, and particularly preferably 30 to 33 according to VDI standard 3400. Preferably, the outer surface of the outer wall and/or the surface facing the outer wall, of the inner wall is ground, eroded and/or sandblasted. The macro-topography may be formed by recesses. The recesses are formed in a recessed manner relative to the surrounding surface of the outer wall and/or the inner wall. In other words, the macro-topography is a structure which, recognizable for the user, has various planes. A micro-topography is, on the other hand, a surface-topography which is recognized to be formed in one plane of the surface by the user. The micro-topography comprises preferably a surface roughness in the range of micrometers and/or below. Alternatively or additionally to the recesses, the macro-topography may also comprise bumps. The bumps are formed in a projecting manner relative to the surrounding surface of the outer wall and/or inner wall. The recesses/bumps are at least 0.5 mm, preferably at least 1 mm deep/high. Preferably the recesses/bumps have a recessed/projecting area of more than 10 mm2 and particularly preferably of more than 100 mm2.

Advantageously, the micro-topography or the macro-topography is at least partially uniformly distributed at at least one portion of the peripheral region. Advantageously, the microtopography and/or the macro-topography is formed at least at the side facing the user, particularly preferably at the front side. Preferably, at least 10%, at least 30%, or at least 50% of the entire surface of the outer wall is configured translucently wherein the remaining surface is preferably intransparent.

By means of the micro-topography and/or the macro-topography it is particularly easy to manufacture a translucent portion in the peripheral region at economic costs. Additionally, depending on the specific configuration of the macro-topography, the stiffness of the peripheral region can be positively influenced. Alternatively or additionally, translucence may be achieved by a murky or opaque outer and inner wall, for example by means of a wall material which comprises a sufficient number of spattering centers.

Particularly preferably, the outer wall and the inner wall are spaced apart at least partially in a constant distance. In other words, the outer wall and the inner wall form advantageously a double wall structure. Particularly preferably, the outer wall and the inner wall are arranged concentrically to each other. Further preferably, the double wall structure of the peripheral region is at least partially configured as a substantially airtight body in which an isolation medium is preferably contained. Particularly preferably, the isolation medium is a transparent or translucent medium, for example air. The isolating structure of the container disclosed here is independent from other aspects of the technology disclosed herein and may also be used in differently configured devices. All other aspects of the disclosed technology may additionally be performed without this isolating structure.

Particularly advantageously, the curvature of the outer wall and the inner wall as well as the distance between the outer wall and the inner wall may at least partially be selected such that a higher refraction occurs in the peripheral region. Particularly advantageously, the microtopography and/or the macro-topography are at least partially configured such that a higher refraction and/or spattering occurs in the peripheral region.

Preferred materials for the peripheral region are, for example, acrylic glass (polymethylmethacrylate (PMMA)), polycarbonate (PC), polyvinylchloride (PVC) polystyrene (PS), polyphenylene ether (PPO), and/or polyethylene (PE). Particularly preferably, the peripheral region is made from polycarbonate. For example, the material itself may be transparent (=100% transparent) or partially transparent (e.g., 30% to 99% transparent) in the peripheral region and the translucence may be achieved by a mattfinish (e.g., by the roughness) of the suface(s).

Further preferred, the peripheral region is at least partially made of a material which is translucent itself and/or comprises a higher refraction.

An elevated refraction is a preferred possibility to only inform the filling level to the user. Additionally advantageously, potential reflections, which may disturb the user, on the outer side of the container may be prevented.

The container comprises an outlet opening in the lower portion. The outlet opening is configured such that a beverage outlet can be guided therethrough. The beverage outlet may be configured integrally with the beverage bag. For example, the beverage outlet may be a V-Top® beverage outlet of the company Smurfit. Particularly preferably, the outlet opening is formed in the bottom region and/or the lower portion of the peripheral region. Such an opening allows for a particularly easy filling of the container with the beverage bag. Advantageously, the bottom region may be inclined towards the outlet opening. By means of the inclined bottom, the final emptying of the beverage bag can be improved.

Particularly preferably, the device comprises besides the container additionally a base portion. In the operation position of the device, the base portion can be arranged below the container. The base portion supports the container. In a device comprising the base portion, the container is arranged higher than in a device without a base portion. Particularly preferrably, the base portion has such a height that a glass, a mug or a cup or another vessel can be arranged below the beverage outlet.

The base portion may comprise a notch for receiving the beverage outlet. Preferrably, the base portion comprises an upper rim. Advantageously, the notch in the base portion is configured openly towards the upper rim. Preferably, the notch of the base portion and the outlet opening of the container are arranged in a corresponding manner such that the beverage outlet of the tube bag can be guided through the outlet opening and can be inserted into or fixed in the notch of the base portion. Particularly preferably, the notch is configured as a U-shaped or V-shaped notch which comprises a collar having an increased thickness compared to the surrounding wall of the base portion. Preferably, the beverage outlet is received in the notch in a form-fit manner and secured against displacement. Advantageously, the container and the base portion are detachably connected to each other. Particularly preferably, the container lays on a bottom plate of the base portion. Thus, it can be easily achieved that first the beverage bag can be placed in the container and the beverage outlet can be guided through the outlet opening before the container is placed onto the base portion. Thereby, the beverage outlet can be easily and comfortably inserted into the notch of the base portion.

The device may additionally also comprise a removable cover which can be fixed to the base portion and/or the container. Advantageously, the cover is such configured and arranged that it covers the outlet opening. The cover may comprise a cover recess which together with the notch of the base portion encloses the beverage outlet. Preferably, different covers can be used for different beverages. Advantageously, the beverage bag can thus also not be seen through the outlet opening. The cover can also reduce the risk that dirt can enter the container and/or the base portion. Advantageously, the base portion may comprise a removable drip pan.

The container may advantageously comprise a lid. Preferably, the lid seals the container. Advantageously, there is provided a holder for at least one cooling pack or non-electric cooling element on the inner surface of the lid. Advantageously, the holder for the at least one cooling pack comprises multiple ridges comprising projections at their end portions. Advantageously the holder, particularly the ridges, are arranged and formed such that at least one cooling pack can be inserted laterally. Preferably, the holder holds the cooling pack in a form-fit manner.

Beverage dispensers are often used in places where they are submitted to a strong heat development by the lighting. For example, beverage dispensers are used for providing beverages at a breakfast buffet. In order to have an illumination as good as possible for the buffet, very bright lights are often used which emit a lot of heat. This radiation usually hits the dispenser from above. Thus, the dispenser is heated from above. Due to the arrangement of the cooling pack disclosed herein the heat source and the heat sink are, thus, arranged near to each other. Advantageously, the developing heat can, thus, immediately be compensated by the cooling pack. Further advantageously, cold air drops downwards such that the beverage bag is uniformly cooled.

The lid including a holding structure disclosed herein is independent from the further aspects of the technology disclosed herein and may be used in differently configured devices as well. All remaining aspects of the disclosed technology may also be performed without said lid including a holding structure.

Preferably, the device for dispensing beverages or the beverage dispenser is a device having a container or a container and a base portion, which is/are configured such that, in the operation position, the beverage can be dispensed only for gravitation. In other words, there is no additional pumping or additional electric power required for operating the device. Particularly preferably, it is a cooled dispenser. Additionally advantageously, the container is configured such that at least the translucently formed portion of the peripheral region is a part of the visual outer wall of the device when the device is in the operation position. In other words, the translucently formed portion of the peripheral region is arranged such that a user when using the device can recognize the filling level of the container or the beverage bag.
