Definitions

  • the invention relates to an adapter arrangement according to the preamble of claim 1.
  • CO 2 containers ie containers in which carbon dioxide (CO 2 ) is stored, are used to enrich liquids with carbonic acid.
  • Carbon dioxide is preferably stored in liquid form in the CO 2 containers, which can in particular be in the form of bottles.
  • the liquids can be water or other beverages.
  • the enrichment of liquids with carbonic acid takes place in carbonation machines, which can be used in particular as compact table devices in private households, offices and the like.
  • the liquid to be carbonated is stored in a liquid container which can be connected to a connection of the carbonation machine, the interface between the connection and the liquid container being sealed.
  • the carbonation machine also has a conveyor unit to which a CO 2 container can be connected.
  • the CO 2 container has a connection head with a valve.
  • the carbonation machine is operated in such a way that the CO 2 container is first connected to the conveyor unit with its connection head.
  • the delivery unit is actuated via an actuating mechanism and thereby the valve in the connection head of the CO 2 container, so that carbon dioxide is discharged from the CO 2 container and fed to the liquid container, whereby the enrichment of the liquid with carbonic acid takes place.
  • the CO 2 containers advantageously form reusable units such that empty CO 2 containers can be refilled with carbon dioxide in filling devices in order to then be able to be used again for a carbonation machine.
  • carbon dioxide is introduced via the valve in the connection head.
  • the filling device typically has filling heads that are placed on the connection head of the respective CO 2 container.
  • connection heads of the CO 2 containers there are also different types of connection heads for containers.
  • the object of the invention is to provide a system that enables flexible use of CO 2 containers.
  • the invention relates to an adapter arrangement with an adapter and a CO 2 container, the CO 2 container having a connection head with a valve.
  • the connection head forms a first interface, by means of which the connection head can be connected to a first conveyor unit, by means of which carbon dioxide can be removed from or fed to the CO 2 container.
  • the adapter has an interface that corresponds to the first interface and by means of which the adapter can be attached to the connection head.
  • the adapter forms a second interface which is designed for connection to a second conveyor unit and which is designed differently from the first interface.
  • the adapter arrangement according to the invention forms a modular system that enables a more flexible, extensive use of CO 2 containers.
  • the CO 2 containers are generally used to store carbon dioxide, especially in liquid form.
  • the CO 2 containers have a connection head with a valve.
  • a conveyor unit can be connected to this connection head, which is in particular a component of a carbonization machine.
  • Carbon dioxide can be discharged from the CO 2 container in a known manner via the connection head with the valve and the delivery unit connected to it and fed to a liquid container which is connected to the carbonation machine. This allows liquid in the container to be enriched with carbonic acid.
  • connection head of a CO 2 container can only be connected to a specific type of conveyor unit of a carbonation machine, which limits its possible use.
  • the adapter of the adapter arrangement according to the invention can be used to connect another type of delivery unit.
  • the adapter has an interface that corresponds to a first interface of the connection head and a second interface that differs from the first interface.
  • the CO 2 container can be connected directly to this first conveyor unit with a first interface.
  • the CO 2 container can also be used for a second delivery unit that differs from the first delivery unit.
  • the adapter is attached with its corresponding interface to the first interface. Then the conveyor unit can be connected to the second interface of the adapter.
  • the adapter arrangement according to the invention can also be expanded to the effect that a modular system of several different adapters is used, which differ from one another in terms of the designs of their corresponding interface and/or second interface, so that a large number of different CO 2 containers are combined with different conveyor units can be.
  • the conveyor unit which can be connected to a CO 2 container directly or via an adapter depending on the design, can be designed as a component of a carbonation machine as a removal unit, by means of which carbon dioxide is removed from the CO 2 container.
  • the or each conveyor unit can also be part of a filling device. Carbon dioxide is then supplied to the respective container by means of the conveyor unit.
  • the first and second interfaces have different mechanical interface elements.
  • the mechanical interface element of the first interface of the connection head is particularly advantageously designed in the form of an external thread and the mechanical interface element of the corresponding interface of the adapter is designed in the form of an internal thread into which the external thread can be screwed.
  • the mechanical interface element of the second interface of the adapter is advantageously formed by a cylindrical lateral surface of the adapter.
  • connection head can also have an internal thread. Then the mechanical interface element of the corresponding interface of the adapter has an external thread.
  • the adapter converts threaded connections to unthreaded connections.
  • the adapter has a cavity which opens out on its underside and in which the internal thread is provided.
  • the mechanical interface element of the second interface of the adapter is provided on its upper side.
  • the adapter can then be placed with the cavity on the connection head.
  • the adapter has only a small overall height. This means that a CO 2 container with an adapter is only slightly larger than a CO 2 container without an adapter. This is an important prerequisite for using CO 2 canisters with adapters in carbonation machines that are conceptually designed for CO 2 canisters without adapters.
  • the adapter has a valve connection means which, when the adapter is mounted on the connection head of a CO 2 container, is in operative connection with a valve connection element in the connection head.
  • valve connection means is expediently formed by a pressure pin running in the axial direction of the adapter.
  • the valve connection element is formed by a release pin running in the axial direction of the connection head.
  • the valve connection means converts an actuation of an actuation mechanism of the carbonation machine to the valve connection element, so that carbon dioxide can escape from the CO 2 container and can be fed to a liquid container on the carbonation machine, whereby a liquid stored there is enriched with carbonic acid.
  • the routing of the carbon dioxide escaping from the CO 2 container is advantageously accomplished in that at least one channel runs in the adapter, via which carbon dioxide flowing out of the valve of the connection head is fed to an outlet opening.
  • the or each outlet opening expediently opens out on the cylindrical lateral surface of the adapter.
  • the or each outlet opening is particularly advantageously located in a groove running around in the circumferential direction of the adapter and opening out on the lateral surface.
  • the circumferential groove distributes the carbon dioxide flowing out via the outlet opening in the circumferential direction of the adapter. This has the advantage that an opening in the delivery unit via which the carbon dioxide is passed on does not have to be positioned exactly at the point of the outlet opening.
  • the adapter has an actuation section.
  • the actuating section expediently has a polygonal lateral surface.
  • a user can attach the adapter to the connection head by means of the actuating section without using tools, in particular screwing the internal thread on the adapter onto the external thread of the connection head. Due to the polygonal cross-section of the actuation section, the user has a good grip and can therefore easily attach the adapter to the connection head.

By actuating the valve 5 carbon dioxide can be discharged from the CO 2 tank 2 . If the container is empty, carbon dioxide can be refilled into the CO 2 container 2 via the connection head 4 .
  • Such CO 2 containers 2, of which different embodiments exist can be used in carbonization machines 6.
  • Such a carbonization machine 6 is shown schematically in figure 5 shown.
  • the carbonization machine 6 has a receptacle 7 on which a liquid container 8 is mounted, with the seams between the liquid container 8 and the receptacle 7 being sealed.
  • a CO 2 container 2 is mounted on a conveyor unit 9 .
  • carbon dioxide is discharged from the CO 2 container 2 by means of the conveyor unit 9 and fed to the liquid in the liquid container 8, as a result of which the liquid is enriched with carbonic acid.
  • the liquid can be water or a drink in general.
  • figure 1 shows a CO 2 container 2, which has a first interface, which has an external thread 10 as a mechanical interface element.
  • This first interface is for a connection to the conveyor unit 9 of the carbonization machine 6 according to figure 5 not suitable.
  • the adapter 3 according to the invention is provided. This ensures that the first interface is converted into a second interface that can be connected to the conveyor unit 9 of the carbonization machine 6 .
  • the adapter 3 has a lower area with a cavity which opens out on the underside of the adapter 3 .
  • An internal thread 11 is provided on the side walls delimiting the cavity.

  • figure 4 shows another type of CO 2 container 2a.
  • the connection head 4 of this CO 2 container 2a already has the first interface with the cylindrical lateral surface 12 and can therefore be connected directly to the conveyor unit 9 of the carbonization machine 6 .
  • the CO 2 container 2 according to FIG. 1 can only be connected to the delivery unit 9 with the adapter 3 seated thereon.
  • an operating portion 15 is provided which has a polygonal cross section. There, a user can grip the adapter 3 and screw it onto the connection head 4 of the CO 2 container 2 .
  • the adapter 3 is screwed with the internal thread 11 onto the external thread 10 of the connection head 4 of the CO 2 container 2 .
  • ducts 16 run from the ceiling of the cavity to the outlet openings 14.
  • two ducts 16 are provided, each leading to an outlet opening 14, although this is not mandatory.
  • a seal 17 is provided in the area of the ceiling.
  • Each channel 16 runs in the vertical direction in the adapter 3 and has a horizontal branch which leads to the respective outlet opening 14 .
  • the outflow directions of the carbon dioxide discharged via the outlet openings 14 are in figure 2 denoted by arrows I.
  • a pressure pin 18 is provided in the center of the adapter 3 as a valve connection means and runs along the longitudinal axis of the adapter 3 .
