Definitions

  • the present invention relates to an intermediate piece for connecting a liquid container to a beverage dispensing system.
  • the present invention further relates to a valve piece for connecting a liquid container to a beverage dispensing system as well as a closure system and a liquid container.
  • Beverage dispensing systems are used in restaurants, bars, cruise ships, and cinemas, for example, to make drinks easily available.
  • Soft drinks and fruit juices in particular can be dispensed and usually filled directly into glasses or cups. Filling can be done by consumers or by staff.
  • a syrup or other liquid is usually used and dispensed on request with water and, if necessary, carbon dioxide.
  • the drinks are prepared on site by mixing them with water and, if necessary, carbon dioxide, so that only the syrup needs to be transported to the place of consumption.
  • liquid bags are usually used as liquid containers, which are then connected to the beverage dispensing system via hose systems, where the actual mixing with water takes place.
  • the closure of such liquid containers enables efficient filling of the liquid container in a bottling system on the one hand, and efficient removal from the beverage dispensing system on the other.
  • Closures in which a so-called fitting is inserted into a liquid container as a connecting piece, for example using an adhesive or welding process, are widespread in this context.
  • a valve can then be inserted, pressed or clicked into this fitting, creating a liquid-tight connection for transporting the liquid container.
  • the valve can then ensure that the liquid can be connected to the beverage dispensing system.
  • a corresponding hose can be connected to the valve using a corresponding connecting piece, with the valve being pressed open when the connection is made.
  • valves are relatively complex to manufacture because, in addition to producing a base body using the injection molding process, a tappet and a spring are often required for the valve function, which are usually made from other materials and also require assembly.
  • a side effect in this context is that when disposing of used liquid containers with valves, various materials have to be disposed of.
  • a liquid bag and an injection molded part of the valve both of which can be made from polyethylene
  • a metal part for the spring and another plastic for other components of the valve may also be necessary. Recycling then often requires material separation, which can be very costly and can also result in a violation of legal regulations or voluntary commitments by beverage suppliers.
  • the present invention has the task of providing an approach for connecting a liquid container to a beverage dispensing system that is compatible with existing systems and devices on the one hand and enables efficient manufacturability and efficient disposal or reuse on the other.
  • an approach is to be provided that requires no or only minor adjustments to installed beverage dispensing systems and to established processes at the beverage suppliers and users.
  • recycling of existing packaging is to be simplified.
  • one aspect of the present invention relates to a closure system for connecting a liquid container to a beverage dispensing system, with an intermediate piece as described above and a valve piece as described above.
  • one aspect of the invention relates to a liquid container with an intermediate piece or with a closure system as described above.
  • an intermediate piece which connects the connecting piece of the liquid container to a valve piece.
  • the valve piece or the valve itself is therefore no longer directly connected to the connecting piece of the liquid container, but is coupled to an intermediate piece.
  • the previously provided two-part structure consisting of a connecting piece on the liquid container and a valve is replaced by a three-part structure consisting of a connecting piece on the liquid container, an intermediate piece and a valve piece.
  • the three-part division enables coupling so that the valve piece can be used as a separate component can be reused.
  • the fact that the intermediate piece is designed according to the invention as a rigid component without moving components enables it to be disposed of easily.
  • a rigid component without moving components is understood in particular to mean a component that can be manufactured using an injection molding process without further assembly steps.
  • the intermediate piece does not contain the moving components that are required for a valve to function and can therefore be disposed of without dismantling.
  • the waste generated is therefore sorted by type.
  • the valve piece according to the invention can be used multiple times. Disposal can then either be provided for or disposal as a mixed component with several components made of different materials can be simplified by the fact that the valve piece means a significantly smaller amount of material to be disposed of than a liquid container with an irreversibly connected valve. The amount of waste generated with mixed materials is significantly reduced.
  • the intermediate piece according to the invention is essentially made up of two parts, a lower section and an upper section.
  • the lower section serves to couple or connect the intermediate piece to a connecting piece of the liquid container.
  • the connection created is preferably a snap-in connection or an irreversible connection, which, once established, cannot be released without causing damage.
  • the coupling to the valve piece provided in the upper section of the intermediate piece is preferably a reversible connection, which can also be released without causing damage, at least with regard to the valve piece.
  • the intermediate piece consists of exactly one material, in particular polyethylene.
  • the intermediate piece can preferably be manufactured using the injection molding process.
  • the use of polyethylene enables use in the food sector. It is also easy to dispose of. Manufacturing using the injection molding process enables efficient manufacturing. Costs can be reduced.
  • the upper section is cylindrically constructed along a longitudinal axis, preferably with a diameter that is smaller than a diameter of a cylindrical receiving area of the valve piece, so that the upper section can be received in the receiving area of the valve piece.
  • the longitudinal axis is in particular an axis of symmetry that runs lengthways through the lower section and the upper section.
  • a cylindrical structure enables easy coupling to corresponding coupling systems of a hose.
  • efficient manufacturing is achieved.
  • the receiving area of the valve piece can in particular be designed for clicking in or inserting/locking the upper section of the intermediate piece. For example, appropriate projections and recesses on both components involved can enable clicking and locking, which cannot be released without causing damage. This results in efficient manufacturing and efficient usability.
  • the intermediate piece comprises a fastening element arranged in the upper section for reversibly fastening the valve piece to the intermediate piece, preferably by a relative rotation between the valve piece and the intermediate piece, in particular a relative rotation about a longitudinal axis of the intermediate piece.
  • the fastening element is preferably arranged in an area of the upper area.
  • the fastening element enables the valve piece to be detachably fastened to the intermediate piece.
  • the valve piece can be secured to the intermediate piece, for example, by a rotary movement.
  • the intermediate piece is usually irreversibly connected to the connecting piece of the liquid container as soon as it is filled.
  • the valve piece can then be secured to the intermediate piece for the purpose of connecting it to the beverage dispensing system.
  • the fastening element itself can, for example, require a relative rotation around a longitudinal axis of the intermediate piece for securing. A relative rotation enables simple fastening, so that an operator can operate it easily.
  • the fastening element comprises a radial projection in an outer circumference of the upper section, which is designed to interact with a receptacle in a circumference or an inner circumference of the valve piece.
  • the projection preferably comprises a hook for locking with a corresponding counter hook of the receptacle of the valve piece.
  • the radial projection in the outer circumference of the upper section interacts with a receptacle in order to enable the valve piece to be secured to the intermediate piece.
  • the radial projection enables in particular a securing by a relative rotation between the valve piece and the intermediate piece. This can be implemented in a simple manner by using a hook that corresponds to a counter hook. This results in efficient manufacturing on the one hand and simple operation on the other.
  • two combinations of fastening element and receptacle offset by 180° in the circumferential direction can be provided on the intermediate piece or on the valve piece.
  • the intermediate piece comprises a further circumferential radial projection arranged in the lower section.
  • the radial projection is designed to fix the receptacle of the valve piece between the radial projection and the further circumferential radial projection.
  • the circumferential radial projection is a type of bearing or a stop for the valve piece. The valve piece is clamped between the radial projection and the further circumferential radial projection. This results in efficient manufacture and simple operation.
  • the lower section is cylindrically constructed along a longitudinal axis, in particular with a diameter that is smaller than a diameter of a cylindrical receiving area of the connecting piece.
  • the lower section can be accommodated in the receiving area or within the receiving area of the connecting piece.
  • the lower section projects beyond the connecting piece into the liquid container when coupled.
  • a cylindrical structure along a longitudinal axis which again preferably corresponds to a central axis of symmetry that runs through the lower section and the upper section, makes it easy to manufacture.
  • it is easy to operate, since it can be accommodated regardless of the rotational position.
  • the lower section can be pushed into the receiving area of the connecting piece, so to speak. This makes it easy to connect. By projecting into the liquid container, liquid can be efficiently removed from the liquid container. Blocking the flow is avoided.
  • the intermediate piece comprises a circumferential radial elevation arranged in the outer circumference of the lower section and/or a circumferential radial depression arranged in the outer circumference of the lower section for coupling to a corresponding depression and/or a corresponding elevation in an inner circumference the receiving area of the connecting piece.
  • the interaction between the elevation and the depression allows for easy fastening by pressing in.
  • the intermediate piece is thus secured in the connecting piece by reversible deformation of the material.
  • the intermediate piece can be clicked into the connecting piece.
  • the connection is preferably irreversible and cannot be removed without causing damage. On the one hand, this enables efficient manufacturing. On the other hand, it also enables easy operation.
  • the intermediate piece comprises a closure for blocking a connection between the liquid container and the beverage dispensing system in an unopened state.
  • the closure is preferably designed to be opened irreversibly by a spinous process of the valve piece, in particular when the valve piece and intermediate piece are used for the first time.
  • the closure is also preferably arranged in the upper section of the intermediate piece facing the valve piece. The closure enables the intermediate piece to be connected to the connecting piece of the liquid container after it has been filled, in order to close the liquid container in this way. The liquid container is therefore filled through the connecting piece and closed by means of the intermediate piece. Liquid leakage from the intermediate piece is prevented by the closure.
  • the closure is only opened when liquid is to be removed, and in particular when the valve piece is attached to the intermediate piece, so that the liquid outflow is then only prevented by the valve itself.
  • the valve in turn, is only opened when it is used in the beverage dispensing system to draw liquid, in order to allow liquid to flow into the beverage dispensing system. This results in simple operation and efficient manufacturability.
  • the coupling section is constructed in a cylindrical shape along a longitudinal axis.
  • the coupling section has a diameter that is larger than a diameter of an upper section of the intermediate piece, so that the coupling section in its interior forms a cylindrical receiving area for the intermediate piece.
  • the valve piece has a corresponding design corresponding to the intermediate piece, so that a receptacle in the coupling section of the valve piece receives the intermediate piece or encompasses or surrounds it. Because the diameter in the area of the valve piece is larger than the diameter in the area of the intermediate piece, an unhindered flow of the liquid is ensured and the tightness is improved. An edge in the area of the flow of the liquid from the liquid container towards the valve is avoided. This results in easy coupling while providing the relevant function.
  • the valve piece comprises a receptacle arranged in the coupling section for a fastening element of the intermediate piece for reversibly fastening the valve piece to the intermediate piece, preferably by a relative rotation between the valve piece and the intermediate piece, in particular a relative rotation about a longitudinal axis of the valve piece.
  • the valve piece comprises a spinous process for irreversibly opening a closure of the intermediate piece, preferably during a first connection of the valve piece and the intermediate piece, wherein the spinous process is designed in particular as a projection in the axial direction in the receiving area of the valve piece.
  • the valve piece comprises a circumferential radial elevation arranged in the connecting section and a circumferential radial depression arranged in the connecting section for interaction with a coupling for coupling to the beverage dispensing system.
  • the receptacle for the fastening element of the intermediate piece can, for example, comprise a type of counter hook for a hook as a fastening element of the intermediate piece. Hooks and counter hooks can correspond to one another, so that fastening can be achieved by hooking in.
  • the relative rotation therefore causes a hooking onto a receptacle designed as a counter hook in the coupling section of the valve piece. It is particularly advantageous if a relative rotation can be used for connecting or coupling.
  • the spinous process can be used to open a closure of the intermediate piece.
  • a type of predetermined breaking point can be provided on the intermediate piece, which is opened by the spinous process.
  • the spinous process can release this predetermined breaking point, so that liquid can then pass through the intermediate piece into the valve piece.
  • the valve arrangement in the valve piece blocks the outflow of liquid until the liquid container is connected to the beverage dispensing system, for example by means of a corresponding hose or hose connection. In this respect, it is possible for the liquid container to be manufactured and delivered with the connecting piece and intermediate piece attached to it without liquid leaking out.
  • a circumferential radial elevation and a circumferential radial depression can be used to couple it to a correspondingly designed counterpart on the beverage dispensing system or to a hose on the beverage dispensing system.
  • Such depressions and elevations are common coupling points that can be used, for example, by means of a click-in or latching mechanism through stretching and tensioning, possibly using a spring force.
  • the connection section in the valve piece designed in this way results in compatibility with existing systems, so that replacement costs can be reduced and there is no need for adjustment on the part of the beverage dispensing system. In this respect, the overall costs can be minimized and a simple introduction of the inventive approach with intermediate piece and valve piece can be achieved.
  • the intermediate piece comprises a further circumferential radial projection arranged in the lower section, which projects at least partially in the radial direction beyond an outer wall of the receiving area of the connecting piece.
  • a type of bearing is formed by the radial projection that extends beyond the wall, which makes it easy to fix the intermediate piece to the connecting piece.
  • the intermediate piece is also easy to manufacture. This results in a reduction in costs and ease of use, possibly also in an automated filling system, in which the connecting piece on the liquid container is closed by inserting or clicking in the intermediate piece.
  • a liquid container is understood to mean in particular a syrup container for use in soft drink dispensing systems or in juice dispensing systems. Sections refer to adjoining parts or sub-areas.
  • the relative terms top and bottom or upper section and lower section are used only for designation and delimitation. It is understood that the relative position can also be reversed depending on the orientation of the intermediate piece, and top and bottom can be swapped.
  • Coupling here means both an irreversible and a reversible connection of two parts. Coupling or connecting creates a fluidic connection so that fluid, in particular liquid, can pass from the liquid container into the various components or through the various components.
  • Movable components are components that are not firmly connected and can carry out a (relevant) relative movement to the remaining component without causing damage. Movable components carry out relative movements to one another, for example by sliding against one another or sliding away from one another, etc.
  • FIG. 1 A beverage dispensing system 10 is shown schematically. Such systems are used, for example, in restaurants, cinemas or on cruise ships to supply a large number of people with drinks.
  • a beverage container 12 can be placed under a dispensing nozzle 14.
  • a beverage dispensing can then be requested by pressing a button 16.
  • other types of operation can also be provided. For example, soft drinks, juices or alcoholic beverages can be dispensed. In many cases, both carbonated drinks and Drinks as well as non-carbonated drinks can be served.
  • water is usually mixed with syrup or another liquid preparation agent.
  • a mixture can be made in a ratio of 1:3 or less.
  • the syrup or the beverage raw material is usually connected to the beverage dispensing system 10 in a liquid container 18 via a hose 20.
  • the liquid container 18 can also be hung in a corresponding device directly in the beverage dispensing system 10.
  • the liquid container 18 can be stored, for example, in a corresponding shelf in a room provided for this purpose.
  • a new closure system 22 is provided for connecting the liquid container 18 to the beverage dispensing system 10.
  • FIG. 2 a closure system 22 according to the invention is shown schematically.
  • the illustration is to be understood as a schematic perspective view.
  • the closure system 22 comprises an intermediate piece 24 and a valve piece 26.
  • the intermediate piece 24 is connected to a connecting piece 28 of the liquid container 18.
  • the components are shown separately from one another. The connection is made in the direction of the dashed arrow.
  • the components of the closure system 22 are connected to the connecting piece 28 of the liquid container 18.
  • the valve piece 26 and the intermediate piece 24 are each constructed along longitudinal axes (central axes), wherein the longitudinal axes correspond to one another when the intermediate piece 24 is connected to the valve piece 26.
  • a valve is then fixed in the connecting piece 28 of the liquid container to close the liquid container before the liquid container 18 is delivered. This valve can then be used to close the liquid container 18 or the connecting piece 28.
  • a connection to a beverage dispensing system for example via a hose with a corresponding counterpart, is made possible.
  • the previously one-piece valve is replaced by a two-piece structure comprising an intermediate piece 24 and a valve piece 26. Due to this two-piece structure, the intermediate piece 24 does not have to provide a valve function, so that on the one hand a design made of only one single material (since different materials for providing the valve function can be dispensed with) and on the other hand a design without moving components (since no valve function has to be provided) is possible. This means that the intermediate piece 24 can be recyclably improved. In addition, the valve piece 26 can be used multiple times. Finally, compatibility with previous beverage dispensing systems is maintained.
  • the approach according to the invention allows the liquid container 18 to be closed after filling by means of the intermediate piece 24.
  • the liquid container 18 can then be delivered closed and transferred to the place of use. Only at the place of use can the valve function be provided by coupling the intermediate piece 24 to the valve piece 26 and a connection to a beverage dispensing system be established.

  • the circumferential radial elevation 40 has at least partially a wedge-shaped cross-section, so that when the intermediate piece 24 is pressed into the connecting piece, it stretches or deforms and then relaxes when corresponding elevations/depressions in the inner circumference of the connecting piece are passed. This deformation can cause the securing to take place. After the intermediate piece 24 and the connecting piece have been connected, it is no longer possible to separate them without causing damage.
