Description

Technical Field

[0001] The invention relates to a receiving device for receiving bottles on a carbonation machine, wherein the receiving device can be transferred from a bottle receiving state provided for receiving bottles into an installation state in which the bottles are mounted on the receiving device. Background Art

[0002] It is generally known that such receiving devices are components of a carbonating machine, which is provided for carbonating liquids, such as water. Such a carbonating machine is also particularly referred to as a drinking water bubbler and is used as a household appliance for the end consumer. The carbonating machine can in principle be used to carbonate different liquids and to prepare different beverages. For carbonation, the machine typically has a replaceable CO2 cartridge that provides a gas, with which the liquid is doped. The liquid to be carbonated is typically filled into a bottle. The bottle with the liquid is then mounted at the carbonating machine in order to perform the carbonation.

[0003] From EP 3040114 B1 a carbonator for domestic use is known which comprises a carbonation assembly for carbonating a liquid in a bottle using pressurized gas from a filling container and a wedge-shaped clamp for fastening the bottle to the carbonator.

[0004] An important aspect is that the bottle must be securely and stably fastened to the machine, since during carbonation there is an increased pressure. In order to reliably withstand this pressure and thus prevent the bottle from undesirably coming loose from the machine, a correspondingly secure and stable connection must be produced between bottle and machine. At the same time, the connection must be user-friendly and comfortable to release after carbonating the liquid and preferably be designed for a high number of carbonation processes over its service life. Summary of the invention

[0005] The object of the present invention is to provide a receiving device for receiving bottles on a carbonation machine which allows a user-friendly and at the same time secure and stable fastening of the bottle on the carbonation machine.

[0006] This object is achieved by a receiving device for receiving a bottle for a carbonating machine.

[0007] The receiving device is capable of being switched from a bottle receiving state configured to receive the bottle to an installation state in which the bottle is mounted on the receiving device, wherein the receiving device has a fastening device for fastening the bottle, wherein the fastening device includes a locking element, wherein the locking element has a guiding device, wherein the receiving device is set in such a way that when the receiving device is switched from the bottle receiving state to the installation state, the locking element is guided by means of its guiding device in such a way that the bottle is fastened by means of the locking element. According to the present invention, the locking element is capable of pivoting about a locking element axis, wherein the locking element is arranged in a radially outer position in the bottle receiving state, wherein when the receiving device is switched from the bottle receiving state to the installation state, the locking element is pivoted about its locking element axis from its radially outer position to a radially inner position, wherein the radially inner position is provided for fastening the bottle, wherein the fastening device comprises a further locking element, wherein the further locking element has a further guiding device, wherein the receiving device is configured such that when the receiving device is switched from the bottle receiving state to the installation state When in the installed state, the additional locking element is guided by means of its additional guide device in such a way that the bottle is additionally secured by means of the additional locking element, wherein the additional locking element is pivotable about an additional locking element axis, wherein the additional locking element is arranged in a radially outer position in the bottle receiving state, wherein when the receiving device is converted from the bottle receiving state to the installed state, the additional locking element is pivoted about its additional locking element axis from its radially outer position to a radially inner position, wherein the radially inner position of the additional locking element is provided for securing the bottle.

[0008] The receiving device according to the invention for receiving a bottle at a carbonating machine has the following advantages over the prior art, namely: the fastening device is provided with a locking element, wherein the locking element has a guide means. It is advantageously possible that when the receiving device is converted from the bottle receiving state into the installed state, the locking element is guided by its guide means in such a way that the bottle is fastened to the receiving device by means of the locking element so that the bottle can no longer escape downward from the receiving device. Therefore, a user-friendly and at the same time reliable fixation of the bottle can be achieved. It is possible that the bottle still has a gap even in the installed state and can still move in a region, in particular in a direction parallel to its central axis. However, the bottle is preferably no longer removable from the receiving device in the installed state, thereby limiting the gap of the bottle in particular downward. It is therefore particularly conceivable that the bottle is fastened to the receiving device with a gap in the installed state by the fastening device and in particular by means of the locking element, but can no longer be removed and is fixed to prevent undesired release from the receiving device.

[0009] According to the invention, it is advantageously possible by means of the guide means of the locking element that when the receiving device is switched from the bottle receiving state to the installation state, the locking element is automatically forced to be guided radially inwards in the direction of the bottle, so that the bottle is fixed or tightened in such a way that it can no longer slip downwards from the receiving device. It is thus possible to mount the bottle at the receiving device by means of the locking element, which bottle also reliably withstands the high pressures during carbonation. At the same time, a particularly high user comfort can be achieved, because when the receiving device is switched from the bottle receiving state to the installation state, the bottle can be automatically tightened, in particular without having to operate a separate mechanism or trigger (e.g. a button) for this purpose. In addition, no motorized structures or the like are required for fixing and reliably tightening the bottle, which can reduce the error-proneness and costs. In addition, according to the invention, it is not necessary to screw the bottle into the carbonator in a cumbersome manner. It is therefore advantageously possible according to the invention to abandon the threaded connection between the bottle and the carbonator.

[0010] By virtue of the fact that the locking element has guide means, a particularly high stability of the locking element can also be achieved, so that the locking element has a long service life on the one hand and is less susceptible to damage on the other hand.

[0011] According to the invention, it is conceivable that when the receiving device is transferred from the bottle receiving state into the installation state, the bottle performs a tilting movement, by which the bottle is transferred from the particularly inclined receiving position (in the bottle receiving state) into the particularly vertical preparation position (in the installation state). According to the invention, it is possible to secure the bottle with the aid of a securing device, particularly preferably during the tilting movement of the bottle from its particularly inclined receiving position (in the bottle receiving state) into its particularly vertical preparation position. In the preparation position, the bottle preferably still has play within the receiving device. However, the securing device prevents the bottle from being able to escape from the receiving device in the preparation position of the bottle.

[0012] In the bottle receiving state of the receiving device, the bottle can be received by the carbonating machine by means of the receiving device, in particular can be inserted into the carbonating machine by a user.

[0013] According to the invention, it is conceivable that the transfer of the receiving device from the bottle receiving state into the installation state is achieved by a tilting movement of the bottle. The tilting movement of the bottle can be achieved, for example, by a user who moves the bottle from the receiving position into the preparation position. As an alternative or in addition, it is possible that the bottle (especially after the bottle has been received in the carbonator by means of the receiving device) automatically and especially without additional force expenditure by the user performs a tilting movement from the receiving position into the preparation position by gravity. As an alternative or in addition, it is conceivable that the carbonator and the receiving device, especially for receiving the bottle, are loaded with a spring force, wherein the spring force (especially after the bottle has been introduced into the carbonator in the bottle receiving state) causes and / or supports the tilting movement of the bottle.

[0014] According to the invention, it is conceivable that in the bottle receiving state, in particular when receiving or inserting a bottle, the bottle is not yet fastened to the carbonator or to the receiving device for receiving the bottle. It is therefore particularly advantageously possible that when receiving the bottle in the bottle receiving state, the bottle does not have to be fastened separately. Thus, for example, screwing the bottle into the carbonator can be dispensed with. In an advantageous manner, the fastening / fixing of the bottle is only carried out, in particular automatically, when the receiving device is switched from the bottle receiving state to the installation state, which increases user comfort and facilitates operability.

[0015] Typically, for the provided carbonation of the liquid in the bottle, a reliable fixation of the bottle is required, without the bottle being loosened from the carbonation machine, and the bottle can also reliably withstand the high pressures occurring during the carbonation. According to the invention, it is possible to achieve such a reliable fixation of the bottle only when the receiving device is converted from the bottle receiving state to the installation state, that is, in particular after the bottle is received in the bottle receiving state by means of the receiving device. According to the invention, it is possible to achieve such a fixation of the bottle particularly advantageously by means of a fastening device and in particular by means of a locking element and its guide means. When the bottle is received at the carbonation machine in the bottle receiving state, the fastening device is preferably in an open state, in which the fastening device bottle is not yet fixed. When the receiving device is converted from the bottle receiving state to the installation state, the fastening device and in particular the locking element are automatically converted into a fastening position by means of the guide means, in which the locking element fastens the bottle in particular in a gap manner or prevents the bottle from being removed and released from the receiving device.

[0016] According to the invention, it is preferably conceivable that the carbonator and the receiving device for receiving bottles on the carbonator are provided for domestic use.

[0017] The bottle is preferably made of glass completely or in part. As an alternative or additional solution, it is conceivable that the bottle has plastic and / or metal.

[0018] By means of the receiving device according to the invention for receiving the bottle on the carbonation machine, the bottle can be connected to the carbonation machine in a particularly reversible manner. The bottle can then be released from the carbonation machine preferably after the carbonation process has been completed.

[0019] The bottle is preferably designed in such a way that it withstands an internal pressure that is increased compared to the normal ambient pressure (approximately 1 bar). For example, it is conceivable that the bottle is designed in such a way that it withstands an internal pressure of up to 11 bar, preferably up to 15 bar, further preferably up to 20 bar or up to 25 bar or up to 30 bar (at a temperature of 20° C. and an external pressure of 1 bar) without bursting.

[0020] The carbonation machine can preferably be equipped with a replaceable gas cartridge, in particular a CO2 cartridge, which provides gas for carbonating the liquid. The liquid to be carbonated is preferably filled into the bottle and is particularly preferably already present in the bottle when the bottle is received in the receiving device.

[0021] The liquid to be carbonated can be, for example, water or a flavoured beverage.

[0022] Advantageous embodiments and developments of the invention can be gathered from the description with reference to the drawings.

[0023] According to a preferred embodiment of the present invention, the receiving device has a matching guide device, in particular a matching guide device complementary to the guide device, wherein the receiving device is set so that when the receiving device is converted from the bottle receiving state to the installation state, the locking element is guided by the guide device and the matching guide device so that the bottle is fastened by the locking element. The matching guide device is in particular a part of the matching guide element, which is an element or component of the receiving device that is separate from the locking element. When the receiving device is converted from the bottle receiving state to the installation state, the matching guide element preferably does not perform a tilting movement of the bottle and the locking element together. When the receiving device is converted from the bottle receiving state to the installation state, the matching guide element is therefore preferably kept in a fixed position in a non-movable manner. When the receiving device is converted from the bottle receiving state to the installation state, the locking element therefore particularly performs a relative movement relative to the matching guide element. Through the guide device and the matching guide device, the locking element is preferably forced to perform a locking movement in this relative movement, in which the locking element is guided radially inward and the bottle is particularly fastened to the receiving device. As a result, a particularly advantageous automatic fastening of the bottle at the receiving device can be achieved.

[0024] According to a preferred embodiment of the invention, it is provided that the locking element can be pivoted about a locking element axis, wherein the locking element is arranged in a radially outer position in the bottle receiving state, wherein when the receiving device is transferred from the bottle receiving state into the installed state, the locking element is pivoted about its locking element axis from its radially outer position into a radially inner position, wherein the radially inner position is preferably provided for securing the bottle. Thus, the locking element can preferably be pivoted about the locking element axis and can perform a locking movement from the radially outer position into the radially inner position for fixing and / or securing the bottle. The locking element can be pivoted about the locking element axis, which preferably extends through the end region of the locking element. In particular, it is conceivable that the locking element extends from this locking element axis in a clamp-like manner.

[0025] According to a preferred embodiment of the invention, it is provided that the guide means and in particular the counter-guide means are configured in such a way that when the receiving device is transferred from the bottle receiving state to the installation state, the locking element is pivoted from its radially outer position to its radially inner position by the guide means and in particular the counter-guide means. When the receiving device is transferred from the bottle receiving state to the installation state, the bottle and at least a part of the receiving device perform a tilting movement, by which the bottle is transferred from the inclined receiving position to a particularly vertical fastening position or preparation position. Preferably, the locking element performs a tilting movement together with the bottle and in particular moves with the bottle during the tilting movement of the bottle. This tilting movement of the locking element advantageously causes the guide means to move by the counter-guide means in such a way that the locking element forces an additional locking movement around the locking element axis of the locking element during this tilting movement, in particular from a radially outer position of the locking element to a radially inner position. By the locking movement, the locking element moves in the direction of the bottle and assumes a position in which the locking element contributes to the fastening of the bottle (i.e. in particular fixes the bottle to prevent it from slipping out of the receiving device). Thus, when the bottle is tilted from its inclined receiving position into its in particular vertical preparation position, the bottle is particularly advantageously automatically secured. In particular, the bottle is secured in such a way that it cannot come loose from the carbonator and in particular cannot be squeezed downwards out of the receiving device during the subsequent carbonation process even under high pressure.

[0026] According to a preferred embodiment of the present invention, it is provided that the guide means and / or the counterpart guide means have a latching means, wherein the locking element can be latched in its radially inner position and / or in its outer position by means of the latching means. The latching means can, for example, comprise one or more latching grooves in the counterpart guide means, into which projections, pins and / or bolts of the guide means can be latched. For example, a first latching groove can be arranged in the counterpart guide means so that projections, pins and / or bolts of the guide means are latched in this first latching groove in the radially outer position of the locking element, and / or a second latching groove can be arranged in the counterpart guide means so that projections, pins and / or bolts of the guide means are latched in this second latching groove in the radially inner position of the locking element. Other latching means can also be conceivable, such as, for example, one or more latching protuberances or one or more undercuts. It is conceivable that the guide means and the mating guide means have complementary locking means relative to each other, so that the locking element can be locked in its radially inner position, i.e. in particular in the fastening state of the fastening device, and / or in its radially outer position, i.e. in particular in the open state of the fastening device.

[0027] According to a preferred embodiment of the invention, it is provided that the fastening device comprises a further locking element, wherein the further locking element has a further guiding means, wherein the receiving device is set in such a way that when the receiving device is converted from a bottle receiving state into an installation state, the further locking element is guided by means of its further guiding means in such a way that the bottle is additionally fastened by means of the further locking element.

[0028] According to a preferred embodiment of the invention, it is provided that the receiving device has an additional counter-guiding means, in particular an additional counter-guiding means complementary to the additional guiding means, wherein the receiving device is set in such a way that when the receiving device is transferred from the bottle receiving state to the installation state, the additional locking element is guided by the additional guiding means and the additional counter-guiding means in such a way that the bottle is fastened by means of the additional locking element. It is preferably conceivable that the additional counter-guiding means is a component of the counter-guiding element, which also has the counter-guiding means. When the receiving device is transferred from the bottle receiving state to the installation state, the counter-guiding element preferably does not perform a tilting movement of the bottle, the locking element and the additional locking element together. When the receiving device is transferred from the bottle receiving state to the installation state, the additional locking element thus performs a relative movement relative to the counter-guiding element. By means of the additional guiding means and the additional counter-guiding means, the additional locking element is forced to perform a locking movement in this relative movement, in which the locking element is guided radially inwards and in particular fastens the bottle in the receiving device.

[0029] Alternatively, it is conceivable that the further counter-guiding means is part of a further counter-guiding element that is separate from the counter-guiding element. In this variant of the invention, the further counter-guiding element preferably also does not carry out a tilting movement of the bottle, the locking element and the further locking element when the receiving device is switched from the bottle receiving state to the installation state. The further locking element thus carries out a relative movement relative to the further counter-guiding element when the receiving device is switched from the bottle receiving state to the installation state. By means of the further guiding means and the further counter-guiding means, the further locking element is forced to carry out a locking movement during this relative movement, in which the further locking element is guided radially inwards and in particular secures the bottle in the receiving device.

[0030] According to one embodiment of the invention, it is conceivable that the further guide means and / or the further counter-guide means have further latching means, wherein the further locking element can be latched into its radially inner position and / or into its radially outer position by means of the further latching means. It is thus possible that the further locking element can be latched into its radially outer position and / or the further locking element can be latched into its radially inner position. The further latching means can, for example, comprise one or more latching grooves in the further counter-guide means, into which further projections, further pins and / or further bolts of the further guide means can be latched. For example, a first further latching groove can be arranged in the further counter-guide means such that a further projection, a further pin and / or a further bolt of the further guide means snaps into this first further latching groove in a radially outer position of the further locking element, and / or a second further latching groove can be arranged in the further counter-guide means such that a further projection, a further pin and / or a further bolt of the further guide means snaps into this second further latching groove in a radially inner position of the further locking element. Other further latching means are also conceivable, such as, for example, one or more latching protuberances or one or more undercuts. It is conceivable that the further guide means and the further counter-guide means have further latching means that are complementary to each other, so that the further locking element can snap into its radially inner position, i.e., in particular in the tightened state of the fastening device, and / or snap into its radially outer position, i.e., in particular in the opened state of the fastening device.

[0031] According to a preferred embodiment of the invention, it is conceivable that the further locking element can be pivoted about a further locking element axis, wherein the further locking element is arranged in a radially outer position in the bottle receiving state, wherein when the receiving device is transferred from the bottle receiving state into the installed state, the further locking element is pivoted about its further locking element axis from its radially outer position into a radially inner position, wherein the radially inner position of the further locking element is preferably provided for securing the bottle. It is preferably possible that the further locking element axis of the further locking element extends parallel to the locking element axis of the locking element.

[0032] It is conceivable that the locking element axis and / or the further locking element axis runs parallel to the central axis of the bottle. In particular, it is conceivable that the locking element axis and / or the further locking element axis is configured parallel to the central axis of the bottle both in the bottle receiving state of the receiving device (when the bottle has been introduced into the receiving device) and also in the ready state of the receiving device. In particular, it is conceivable that the locking element axis and / or the further locking element axis tilts together parallel to the central axis of the bottle during a tilting movement of the bottle (during the transfer of the receiving device from the bottle receiving state into the installation state).

[0033] According to a preferred embodiment of the invention, it is provided that the further guide means and in particular the further counter-guide means are designed in such a way that when the receiving device is transferred from the bottle receiving state into the installation state, the further locking element is pivoted from its radially outer position into its radially inner position by the further guide means and in particular the further counter-guide means. It is preferably possible that when the receiving device is transferred from the bottle receiving state into the installation state, the further locking element performs a tilting movement together with the bottle, wherein the further guide means is guided during this tilting movement by the further counter-guide means in such a way that the further locking element pivots about its further locking element axis from its radially outer position into its radially inner position and thus contributes to the fixing of the bottle and in particular prevents the bottle from being able to slip downwards out of the receiving device.

[0034] According to one embodiment of the invention, it is conceivable that when the receiving device is transferred from the bottle receiving state to the installed state, the locking element and the further locking element are either both pivoted clockwise or both counterclockwise about their locking element axes. Therefore, the locking element and the further locking element are pivoted in particular in the same direction of rotation.

[0035] According to an alternative embodiment of the invention, it is conceivable that when the receiving device is transferred from the bottle receiving state to the installation state:

[0036] - the locking element is pivoted in a left-handed manner about its locking element axis and the further locking element is pivoted in a right-handed manner about its further locking element axis; or

[0037] The locking element is pivoted clockwise about its locking element axis and the further locking element is pivoted counterclockwise about its further locking element axis. Thus, the locking element and the further locking element are pivoted in particular in oppositely arranged directions of rotation.

[0038] According to one embodiment of the invention, it is conceivable that the fastening device is constructed with exactly two locking elements, in particular a locking element and a further locking element. According to an alternative embodiment of the invention, it is conceivable that the fastening device has one or more additional locking elements in addition to the locking element and the further locking element. It is conceivable that the one or more additional locking elements are constructed corresponding to the locking element. It is conceivable that when the receiving device is converted from the bottle receiving state to the installation state, all the locking elements of the fastening device are respectively converted from their radially outer positions to their radially inner positions, wherein the radially inner positions are preferably provided for fastening the bottle in the receiving device. It is conceivable that when the receiving device is converted from the bottle receiving state to the installation state, all the locking elements are pivoted in the same direction of rotation, that is, in particular all are pivoted in a right-handed manner or all are pivoted in a left-handed manner. Alternatively, it is conceivable that when the receiving device is converted from the bottle receiving state to the installation state, the locking elements are partially pivoted in a right-handed manner and partially in a left-handed manner.

[0039] According to a preferred embodiment of the invention, it is provided that the bottle can be arranged on the receiving device in a particularly non-vertical receiving position in the bottle receiving state of the receiving device, wherein the bottle is arranged in a particularly vertical preparation position in the installed state. The particularly non-vertical or inclined receiving position or receiving orientation of the bottle and the particularly vertical preparation position or preparation orientation relate, for example, to the orientation of the central axis of the bottle relative to the base on which the carbonator is arranged. The bottle is then arranged, for example, perpendicularly to the base in the vertical preparation position and is inclined in the non-vertical receiving position compared to the vertical preparation position.

[0040] According to a preferred embodiment of the invention, it is provided that when the receiving device is transferred from the bottle receiving state to the installation state, the bottle performs a tilting movement from a particularly non-vertical receiving position to a particularly vertical preparation position. The receiving device for receiving the bottle is preferably at least partially pivoted or tilted together with the bottle when the bottle receiving state is transferred to the installation state, so that the bottle is transferred from the non-vertical receiving position to the vertical preparation position. However, preferably not all elements of the receiving device are tilted or moved together. For example, it is conceivable that the matching guide means, other matching guide means and / or matching guide elements of the receiving device do not move and tilt together, but are held immovably in their position at the carbonator.

[0041] Alternatively, it is conceivable that the bottle is arranged in a non-vertical preparation position in the installed state, so that its central axis is arranged, for example, at an angle to the surface normal of the surface on which the carbonator is arranged. In this case, it is conceivable to carry out carbonation in the non-vertical preparation position of the bottle. However, in this case, when switching from the bottle receiving state to the installed state, the bottle mounted on the receiving device is preferably also tilted or changes its angle relative to the base. Thus, when switching from the bottle receiving state to the installed state, the bottle and the receiving device provided for receiving the bottle at least partially perform a tilting movement or a rotational movement.

[0042] According to a preferred embodiment of the invention, it is provided that the guide means have a projection, a pin and / or a screw, wherein preferably the further guide means have a further projection, a further pin and / or a further screw.

[0043] According to a preferred embodiment of the invention, it is provided that the counter-guide means has a guide track, in particular a recess and / or a deepening, which is provided for guiding the guide means, wherein preferably the further counter-guide means has a further guide track, in particular a further recess and / or a further deepening, which is provided for guiding the further guide means. This allows a particularly advantageous automatic fixing of the bottle.

[0044] Alternatively, it is conceivable that the guide means has a guide rail, in particular a recess and / or a deepening, wherein preferably the other guide means has another guide rail, in particular another recess and / or another deepening. In this case, the counterpart guide means preferably has a projection, a pin and / or a bolt, which is embedded in the guide rail of the guide means and is guided in this guide rail. Preferably, correspondingly, the other counterpart guide means has another projection, another pin and / or another bolt, which is embedded in the other guide rail of the other guide means and is guided in this other guide rail. Combinations are also conceivable. For example, it is feasible that the guide means has a projection, a pin and / or a bolt, and the counterpart guide means has a guide rail complementary thereto, wherein the other guide means has a guide rail, and the other counterpart guide means has another projection, another pin and / or another bolt complementary thereto.

[0045] According to a preferred embodiment of the invention, it is provided that the locking element comprises a clip, in particular with a circular arc region, wherein the locking element in the installed state secures the bottle by means of its clip, wherein preferably the further locking element comprises a further clip, in particular with a further circular arc region, wherein the further locking element in the installed state secures the bottle by means of its further clip. Thus, the clip can advantageously be guided from the outside in the direction of the bottle neck during the locking movement and thus fix the bottle or secure it in particular with play on the receiving device. The clip preferably extends perpendicularly to the central axis of the bottle and / or in such a way that it can be arranged or engaged around the bottle neck of the bottle in the circumferential direction.

[0046] According to one embodiment of the invention, it is particularly advantageously conceivable that the bottle has a groove in the circumferential direction, into which the locking element and / or another locking element, in particular a clamp and / or another clamp, can engage. The groove of the bottle is preferably a groove that completely surrounds the neck of the bottle, so that the bottle does not have to be inserted into the carbonator at a predetermined rotation angle.

[0047] As an additional solution or alternative, it is conceivable according to an embodiment of the present invention that the bottle has a protrusion and / or a protuberance in the circumferential direction, which is particularly arranged above the locking element and / or another locking element, especially the clamp and / or another clamp in the installed state. With the help of the protrusion and / or the protuberance, it is particularly advantageous to prevent that the bottle may be squeezed out downward from the fastening device due to the pressure formed during the carbonation process. It is conceivable that the protrusion and / or the protuberance are completely constructed at the bottleneck in the circumferential direction or are alternatively constructed only by partial areas and / or partial sections. The locking element and preferably the other locking element are engaged around the bottleneck in the installed state, especially below the protrusion and / or the protuberance of the bottleneck. Therefore, the protrusion and / or the protuberance of the bottleneck can be placed on the locking element and preferably the other locking element in the installed state, thereby particularly advantageously preventing that the bottle may leak downward from the receiving device. According to one embodiment of the present invention, it is conceivable that the groove is arranged below the protrusion and / or ridge of the bottleneck, particularly preferably next to the protrusion and / or ridge arrangement. Alternatively, it is conceivable that the bottleneck only has this type of groove or has a protrusion and / or ridge.

[0048] As an alternative or in addition, it is conceivable that the locking element and preferably the further locking element engage around a projection and / or a bulge of the bottleneck in the installed state, wherein the projection and / or the bulge of the bottleneck is at least partially surrounded by the locking element and preferably the further locking element.

[0049] According to a preferred embodiment of the invention, it is provided that the clamp, in particular the arc region, spans an angular range of at least 45°, preferably at least 90°, further preferably at least 170°. It is preferably conceivable that further clamps, in particular further arc regions, span an angular range of at least 45°, preferably at least 90°, further preferably at least 170°.

[0050] According to a preferred embodiment of the invention, it is provided that the locking element and its guide means are designed in one piece, wherein preferably the further locking element and the further guide means are designed in one piece. The locking element and the further locking element are preferably separate parts from each other.

[0051] According to a preferred embodiment of the invention, it is provided that the locking element comprises plastic, wherein preferably the further locking element comprises plastic. It is thus possible that the locking element and the further locking element are each a plastic part. It is conceivable that, as an additional or alternative, the locking element and the further locking element comprise another material, for example one or more metals.

[0052] According to a preferred embodiment of the present invention, it is provided that the receiving device has a covering element, wherein the locking element and / or another locking element is preferably arranged behind the covering element, in particular arranged so that the covering element at least partially covers the locking element and / or another locking element. According to a preferred embodiment of the present invention, it is provided that the bottle has a flange, in particular a flange that completely, partially or partially surrounds the neck of the bottle in the circumferential direction. When the user introduces the bottle into the receiving device, in particular in the bottle receiving state of the receiving device, the introduction depth of the bottle in the receiving device is defined in particular by the covering element and the flange of the bottle. The bottle can be introduced in particular only to a certain extent until the flange of the bottle collides with the covering element, in particular from below. By means of the covering element and the flange of the bottle, the introduction depth of the bottle in the receiving device can therefore be determined and / or defined. Therefore, the bottle can be arranged in or at the receiving device in a receiving position in a comfortable and reproducible manner for the user.

[0053] A further subject matter of the invention is a carbonating machine comprising a receiving device for receiving bottles according to one embodiment of the invention.

[0054] According to the present invention, a preferred embodiment of the carbonation machine is provided, wherein the carbonation machine comprises a safety element, in particular a safety door and / or a safety plate, wherein the safety element can be arranged in front of the bottle in the installed state so that the bottle is arranged in the carbonation machine in particular in its entirety by means of the safety element. Therefore, the safety element protects the surroundings of the carbonation machine and in particular the user in the event of an accident. For example, it is conceivable that the bottle has damage that the user does not recognize or cannot recognize. In this case, the bottle may crack or break due to the high pressure during carbonation. However, by arranging the safety element in front of the bottle during carbonation, the safety element protects the surroundings and the user. The safety element can, for example, include safety glass and / or another material, such as, for example, metal and / or plastic, which withstands a broken / exploded bottle or provides protection from the impact of the fragmentation of the bottle. It is conceivable that when the receiving device is converted from the bottle receiving state to the installed state, the safety element is automatically arranged in front of the bottle, for example, is pushed in front of the bottle, or the user arranges the safety element in front of the bottle. It is also conceivable to close the safety element by means of an operating element, such as a button. For example, the safety element can be a sliding door, which is automatically closed when the receiving device is converted from the bottle receiving state to the installation state by the tilting movement of the bottle.

[0055] According to the invention, in particular a preferred embodiment of a carbonator provides that the carbonator comprises a sealing device for sealing the bottle relative to the surroundings during carbonation, wherein the sealing device seals the bottle relative to the surroundings during carbonation, in particular by means of the pressure provided by a gas cartridge. Pneumatic compensation is thereby achieved. In this case, the gas cartridge is in particular a gas cartridge which provides gas for the carbonation of the liquid. It is therefore advantageously possible to achieve sealing of the bottle relative to the surroundings by actuating an operating device, such as a button or a touchpad, for starting the carbonation process. The gas pressure provided by the gas cartridge (during carbonation) is therefore particularly advantageously also used to seal the bottle to the outside during carbonation.

[0056] According to one embodiment of the invention, it is provided that the gas supply device protrudes into the bottle in the installed state and in particular during carbonation. The gas cartridge is connected to the gas supply device so that during carbonation, the gas of the gas cartridge for carbonating the liquid is introduced into the bottle via the gas supply device. The gas supply device is especially guided through the through-opening of the sealing device and thus protrudes into the bottle. The gas pressure provided by the gas cartridge (during carbonation) is preferably also used to press the sealing device against the bottle and thus seal the bottle to the outside during carbonation. In this way, an advantageous carbonation of the liquid in the bottle can be achieved by the gas supply device protruding into the bottle.

[0057] According to one embodiment of the present invention, it is conceivable that the sealing device extends beyond the bottle neck or mouth area of ​​the bottle in a radial direction, so that when the sealing device is pressed against the mouth area of ​​the bottle due to the pressure provided by the gas cylinder, this mouth area is reliably sealed outwardly. The sealing device preferably has a through opening, especially centered, for guiding the gas supply device through, so that the gas supply device protrudes into the interior of the bottle through the sealing device. It is conceivable that the sealing device is at least partially elastic, so that when the sealing device is pressed against the bottle or the mouth area of ​​the bottle, a favorable seal is achieved. In particular, it is also possible to advantageously compensate for the tolerance of the bottle, especially the unevenness at the bottle neck, by means of an elastic or partially elastic sealing device and nevertheless achieve sealing. The sealing device preferably has silicone. It is feasible here that the bottle is fixed and maintained in a fixed position during carbonation by pressure (with which the sealing device is pressed onto the mouth area of ​​the bottle during carbonation). In particular, it is conceivable that the projection and / or ridge of the bottle neck is pressed against the locking element and / or another locking element by the pressure applied to the bottle by the sealing device. Therefore, the bottle is clamped by the sealing device and the locking element and / or another locking element.

[0058] According to one embodiment of the invention, it is conceivable that the carbonator comprises a pressure chamber, wherein the pressure chamber is in particular configured adjacent to the sealing device. Thus, an advantageous automatic sealing of the bottle with respect to the surroundings can be achieved by the pressure chamber and the sealing device. In particular, it is possible that the sealing of the bottle with respect to the surroundings is automatically achieved as soon as the carbonation process is started and the gas cartridge is opened. It is advantageously conceivable that the locking element and preferably further locking elements secure the bottle in such a way that, despite the overpressure generated in the pressure chamber (during carbonation) and / or the pressure exerted on the bottle by the sealing device, this bottle remains securely fastened in the carbonator and in particular cannot be squeezed downwards out of the carbonator.

[0059] According to one embodiment of the invention, it is conceivable that the pressure chamber is connected to the inner cavity of the bottle, especially during carbonation, via a gas connection, preferably connected in such a way that an overpressure provided by the gas cartridge is generated in the pressure chamber during carbonation, wherein the sealing device is pressed against the bottle due to the overpressure in the pressure chamber, especially pressed in such a way that the bottle is sealed relative to the surroundings. The gas connection between the interior of the bottle and the pressure chamber is preferably configured as a channel, especially configured as a channel configured by means of a sealing device. A gas connection is made between the interior of the bottle and the pressure chamber via the channel. If an overpressure is now generated in the bottle due to opening the gas cartridge during carbonation, then an overpressure is also generated in the pressure chamber via the gas connection or the channel. The overpressure in the pressure chamber is then particularly advantageously generated by means of a gas cartridge. This overpressure in the pressure chamber preferably causes the sealing device to be pressed downwards against the bottle, especially against the mouth area of ​​the bottle, which advantageously causes the sealing of the bottle relative to the surroundings.

[0060] A further subject matter of the present invention is a method for using a carbonation machine according to one embodiment of the present invention, wherein the method comprises the following steps:

[0061] In a first step, the bottle is arranged on a receiving device of the carbonating machine in a bottle receiving state of the receiving device, wherein the bottle contains a liquid,

[0062] in a second step, the receiving device is transferred from the bottle receiving state into the mounting state, wherein, during the transfer from the bottle receiving state into the mounting state, the locking element is guided by means of its guide means in such a way that the bottle is fastened to the receiving device by means of the locking element,

[0063] - In a third step, the liquid is carbonated in the bottle.

[0064] It is possible that after carbonation the receiving device is switched back into the bottle receiving state, so that the bottle with the carbonated liquid can be removed.

[0065] It is preferably possible to realize the carbonation of the liquid in the third step by means of a gas cartridge, which provides gas, in particular CO2, for carbonating the liquid in the bottle via a gas supply device protruding into the interior of the bottle. Carbonation can be started, for example, by the user via an operating element, in particular after the receiving device has reached the installation state and / or after the bottle has been switched to the ready position. As operating elements for starting carbonation, buttons, switches, touch pads, acoustic signals and / or other operating elements come into consideration, for example. Alternatively, it is conceivable that carbonation is started automatically after reaching the installation state and / or after safety elements, in particular safety doors and / or safety plates, have been closed.

[0066] According to a preferred embodiment of the invention, in particular of the method, it is provided that the fastening device comprises a further locking element, wherein the further locking element has a further guide means, wherein in a second step, when the receiving device is switched from the bottle receiving state to the mounting state, the further locking element is guided by means of its further guide means in such a way that the bottle is fastened by means of the further locking element. Thus, the bottle is preferably fastened to the receiving device in the second step jointly by the locking element and the further locking element, in particular in such a way that the bottle can no longer be removed from the receiving device. Here, the bottle can be fastened to the receiving device with play in the mounting state, i.e., can be moved, in particular, within the receiving device, parallel to its central axis (in particular upwards / downwards). Thus, the bottle can also move, in particular parallel to its central axis, in its fastened position or ready position, wherein, however, the bottle is prevented from detaching from the receiving device by the fastening device. It is conceivable that after the user releases the bottle, the bottle moves downwards within its play by gravity until its movement is limited by the fastening device, in particular by the locking element and preferably by the further locking element. The bottle is thus held securely in the carbonator in the installed state. After the user has released the bottle, it is thus advantageously possible for the bottle to be held in a well-defined position by gravity and the securing device. In particular, the flange of the bottle rests on the locking element and the further locking element.

[0067] According to one embodiment of the invention, it is conceivable that the bottle performs a tilting movement from a particularly non-vertical receiving position in which the bottle was already arranged in the first step into a particularly vertical preparation position in the second step. Preferably, the receiving device for receiving the bottle is tilted at least partially together with the bottle in the second step so that the bottle is transferred from the receiving position to the preparation position. It is preferably possible that the bottle is fixed in the second step during this tilting movement by means of a locking element and preferably by means of a further locking element, in particular with play. The tilting movement in the second step is particularly caused in such a way that the bottle automatically moves from the receiving position to the preparation position by gravity. As an alternative or in addition, it is possible that the user moves the bottle from the receiving position to the preparation position. As an alternative or in addition, it is possible that the receiving device is loaded with a spring force, in particular loaded in such a way that the bottle automatically transfers from the receiving position to the preparation position in the second step by means of a spring force.

[0068] According to one embodiment of the invention, it is conceivable that during carbonation, an overpressure is constructed in the bottle in a third step by means of a gas cartridge for carbonating the liquid. It is preferably possible to transfer the overpressure constructed in the bottle to the pressure chamber via a gas connection or channel between the inner cavity of the bottle and the pressure chamber of the carbonator, in particular the pressure chamber of the receiving device. Alternatively, a direct gas connection between the pressure chamber and the gas cartridge is also conceivable (during carbonation). Due to the overpressure thus constructed in the pressure chamber, the sealing device arranged at the pressure chamber is pressed downwards in the direction of the bottle. The bottle is pressed downwards by the sealing device against the locking element and in particular the further locking element in the fastened state, wherein the locking element and in particular the further locking element limit the downward movement of the bottle, in particular such that the bottle cannot be pressed out of the receiving device by the sealing device and / or the overpressure. It can therefore be particularly advantageously ensured that the bottle remains in its ready position or fastened position.

[0079] In the various figures, identical components are always provided with the same reference symbols and are therefore generally also mentioned only once.

[0080] exist Figure 1 , a perspective view of a carbonator 1 according to an exemplary embodiment of the invention in a bottle receiving state is shown. The carbonator comprises a receiving device 10. In the bottle receiving state of the receiving device 10, the bottle 2 can be arranged on the carbonator 1 in an inclined, non-vertical receiving position. Correspondingly, the central axis 2′ of the bottle 2 is not arranged vertically, but extends obliquely. By means of a tilting movement 100, the bottle 2 can be transferred from the receiving position into a particularly vertical preparation position.

[0081] The tilting movement 100 of the bottle 2 can be realized, for example, by a user who moves the bottle 2 from the receiving position into the standby position. As an alternative or in addition, it is possible that the bottle 2 automatically and in particular without additional force expenditure by the user performs the tilting movement 100 from the receiving position into the standby position by gravity. As an alternative or in addition, it is conceivable that the carbonator 1 and in particular the receiving device 10 are loaded with a spring force, wherein the spring force causes and / or supports the tilting movement 100 of the bottle 2. According to the invention, it is advantageously possible that a part of the receiving device 10 performs the tilting movement 100 together with the bottle 2, wherein the receiving device 10 is transferred from a bottle receiving state of the receiving device 10 into an installed state in which the bottle 2 is fastened to the receiving device 10.

[0082] A gas cartridge can be introduced on the rear side 1 ′ of the carbonator 1 , which provides gas for carbonating a liquid, in particular water, which is located in the bottle 2 .

[0083] exist Figure 2 The following is shown in Figure 1 A perspective view of the carbonation machine 1 in the installed state, in particular after completion of the tilting movement 100. In the installed state, the bottle 2 is in a vertical fastening position or ready position, so that carbonation can be carried out.

[0084] exist Figure 3 , a perspective view of a carbonating machine 1 according to an exemplary embodiment of the invention is shown. In particular, an installed state is shown, in which carbonation can be carried out. The carbonating machine 1 comprises a safety element 60, in particular a safety door 61. The safety element 60 is arranged in front of the bottle 2 in the installed state such that the bottle 2 is arranged completely within the carbonating machine 1. The safety element 60 thus protects the user of the carbonating machine 1 and the surroundings, for example, from the explosion of the bottle 2. It is possible that the carbonation process can only be started when the safety element 60 is closed.

[0085] exist Figure 4 , a perspective view of a receiving device 10 of a carbonating machine 1 and of the area surrounding the receiving device 10 is shown in accordance with an exemplary embodiment of the present invention. The carbonating machine 1 comprises a gas supply device 53, which protrudes into the bottle 2 when the bottle 2 is in the installed state. The receiving device 10 comprises a covering element 55. The covering element 55 conceals the locking element 30 and the further locking element 40 of the fastening device 20. Furthermore, a receiving part 57 of the receiving device 10 is shown. The receiving part 57 comprises a recess into which the neck of the bottle 2 can be introduced. By means of the receiving part 57, the bottle 2 is guided and positioned when it is introduced into the receiving device 10, which makes the introduction process easier for the user and increases the user comfort.

[0086] exist Figure 5 1 shows a perspective view of a receiving device 10 and the area surrounding the receiving device 10 of a carbonation machine 1 according to an exemplary embodiment of the invention. The cover element 55 is omitted in the illustration so that the rearward part of the fastening device 20 can be seen. The fastening device 20 comprises a locking element 30 and a further locking element 40. Figure 5, the locking element 30 and the further locking element 40 are shown in the open state, which they assume in the bottle receiving state of the receiving device 10 so that the bottle 2 can be introduced. The locking element 30 comprises a clamp 32 which has a circular arc region and is designed to engage around the neck of the bottle 2 in the circumferential direction. The further locking element 40 comprises a further clamp 42 which has a further circular arc region and is likewise designed to engage around the neck of the bottle 2 in the circumferential direction. The locking element 30 can be pivoted about the locking element axis 30′, in particular from Figure 5 The radially outer position shown in FIG. 1 is pivoted to a radially inner position, which is in the radially inner position. Figure 6 4 and corresponds to the closed state of the fastening device 20. The further locking element 40 can be pivoted about a further locking element axis 40', in particular from Figure 5 The radially outer position shown in FIG. 1 is pivoted to a radially inner position, which is in the radially inner position. Figure 6 is shown and corresponds to the closed state of the fastening device 20 .

[0087] The receiving device 10 further comprises a counter-guide element 13. The counter-guide element 13 comprises a counter-guide means 11 and a further counter-guide means 12. The counter-guide means 11 is designed as a guide rail 11′, in particular as a recess in the counter-guide element 13. The pin 31′ of the guide means 31 engages in this guide rail 11′ and is guided by the guide rail 11′. The further counter-guide means 12 is designed as a further guide rail 12′, in particular as a further recess in the counter-guide element 13. The further pin 41′ of the further guide means 41 engages in the further guide rail 12′ and is guided by the further guide rail 12′.

[0088] When the receiving device 10 is transferred from the bottle receiving state to the installation state, the counter-guide element 13 does not carry out the tilting movement 100 of the bottle 2 together, but is held immovably on the carbonation machine 1. Thus, when the receiving device 10 is transferred from the bottle receiving state to the installation state, the locking element 30 and the further locking element 40 carry out a relative movement relative to the counter-guide element 13 (and therefore relative to the counter-guide means 11 and relative to the further counter-guide means 12). By the relative movement, the pin 31 ′ moves in the guide rail 11 ′, in particular from bottom to top. By the geometric design of the guide rail 11 ′, the locking element 30 is forced to carry out a locking movement 33 in which the locking element pivots radially inwards toward the bottle 2. Correspondingly, by the relative movement, the further pin 41 ′ moves in the further guide rail 12 ′, in particular from bottom to top. By the design of the further guide rail 12 ′, the further locking element 40 is forced to carry out a locking movement in which the further locking element pivots radially inwards toward the bottle 2. Therefore, when the receiving device 10 is converted from the bottle receiving state to the installation state, the locking element 30 and the further locking element 40 are automatically converted into a fastening position via the guide device 31 and the mating guide device 11 or via the further guide device 41 and the further mating guide device 12, in which fastening position the locking element 30 and the further locking element 40 fasten the bottle 2 in the receiving device 10, in particular with the gap 101, and prevent the bottle 2 from being removed and released from the receiving device 10.

[0089] exist Figure 6 It is shown in Figure 5 , wherein the receiving device 10 is in the installed state. The locking element 30 and the other locking element 40 have correspondingly implemented their locking motion and are respectively in their radially inner position, that is, in their fastening position. The locking element 30 fastens the bottle 2 (not shown) in the installed state by its clamp 32, which engages around the bottleneck in the circumferential direction. The other locking element 40 fastens the bottle 2 (not shown) in the installed state by its other clamp 42, which engages around the bottleneck in the circumferential direction. The clamp 32 spans an angular range slightly less than 180 ° in the embodiment shown. Correspondingly, the other clamp 42 spans an angular range slightly less than 180 °. Therefore, the clamp 32 and the other clamp 42 can jointly include the bottleneck in their radially inner position substantially completely and prevent the bottle 2 from being pressed out from the receiving device 10 undesirably during carbonation.

[0090] exist Figure 7, a cross-sectional view of a carbonation machine 1 and a bottle 2 according to an exemplary embodiment of the present invention is shown. The receiving device 10 is in a bottle receiving state. The bottle 2 is introduced into the receiving device 10 in an inclined non-vertical receiving position. The receiving device 10 comprises a receiving member 57 with a recessed portion, into which the neck of the bottle 2 is partially introduced. By means of the receiving member 57, the bottle 2 is guided and positioned when the bottle 2 is introduced into the receiving device 10, which makes the introduction process easier for the user and improves the user comfort. During the introduction, the user typically presses the bottle 2 into the receiving device 10 from an inclined bottom, thereby guiding the neck of the bottle into the receiving member 57. This introduction movement of the bottle 2 by the user is advantageously limited upwards by the flange 8 of the bottle 2 and the covering element 55 of the receiving device 10. The flange 8 surrounds the neck of the bottle completely or only partially in the circumferential direction. The bottle 2 can be introduced into the receiving device 10, in particular, only to a certain extent, until the flange 8 of the bottle 2 collides with the covering element 55 from below. The introduction depth of the bottle into the receiving device 10 is thus defined by the cover element 55 and the flange 8 of the bottle 2. In this way, the bottle 2 can be arranged in a receiving position on the receiving device 10 in a comfortable and reproducible manner for the user. As an alternative to the flange 8, different widenings or domes of the bottle 2 are also conceivable. The receiving part 57 and / or the cover element 55 have an especially circumferential introduction bevel, by which the bottle 2 is preferably received, guided and positioned when introduced into the receiving device 10. The introduction bevel is especially designed such that the diameter of the opening of the receiving part 57 and / or of the cover part for receiving the bottle decreases in the introduction direction.

[0091] In accordance with Figure 7 In the bottle receiving state, the guide means 31 of the locking element 30, in particular the pin 31 ′, is arranged below in the counter-guide means 11, in particular the guide rail 11 ′, due to the inclined orientation of the locking element 30. The corresponding situation applies to the further guide means 41 of the further locking element 40, which is arranged below in the further counter-guide means 12, in particular the further guide rail 12 ′. Figure 7 ) to the installation state (see Figure 8), the pin 31′ moves from bottom to top in the guide rail 11′. Due to the design of the guide rail 11′, the locking element 30 is forced to perform a locking movement 33, in which the locking element pivots radially inward toward the bottle 2. Correspondingly, by relative movement, the other pin 41′ moves from bottom to top in the other guide rail 12′, whereby the other locking element 40 is also forced to perform a locking movement, in which the other locking element pivots radially inward toward the bottle 2. Therefore, when the receiving device 10 is converted from the bottle receiving state to the installation state, the locking element 30 and the other locking element 40 are automatically converted into a fastening position by the guide device 31 and the matching guide device 11 or by the other guide device 41 and the other matching guide device 12, in which the locking element 30 and the other locking element 40 fasten the bottle 2 in the receiving device 10 and prevent the bottle 2 from being removed and released from the receiving device 10. Figure 8 The corresponding installed state of the receiving device 10 is shown in FIG. The bottle 2 and the part of the receiving device 10 that can move in a tilting movement have been transferred into a vertical position. Figure 8 Here, the following state is shown in FIG. 5 , in which the user still fixes the bottle 2 and presses it upwards if necessary. Thus, contact is also formed between the flange 8 and the covering element 55 .

[0092] exist Fig. 9 , the installation state after the user has released the bottle 2 is shown. The bottle 2 moves downward within the gap 101 (which the bottle has in the installed state) until the projection 6 of the bottle 2 is placed on the locking elements 30, 40 in the fastening position. It is therefore feasible that the flange 8 no longer touches the covering element 55 and is spaced apart from this covering element. Here, the spacing between the flange 8 and the covering element 55 depends in particular on the size of the gap 101, which the bottle 2 has in the installed state in its vertical fastening position. In the embodiment shown, the projection 6 at the bottleneck has a rectangular cross section and extends outward from the bottleneck. Other shapes and designs, especially other cross-sectional geometries, can also be envisioned for the projection 6. It is preferably feasible that the projection 6 is constructed completely around the bottleneck in the circumferential direction. Alternatively, it is conceivable that the projection 6 is constructed only in sections, especially in an interrupted manner in the circumferential direction. The bottle is fastened to the receiving device by the projection 6 and the locking element 30 and the further locking element 40 so that the bottle 2 cannot be separated from the receiving device 10 in the installed state, so that reliable carbonation can be performed. In this case, due to the clamp-shaped locking elements 30, 40 and their arc sections, a particularly large contact area is formed between the projection 6 and the locking elements 30, 40, which leads to a particularly advantageous mechanical stability.

[0093] It is possible that the bottle 2 has a groove 7, in particular a groove 7 that is completely formed around the neck in the circumferential direction. The groove 7 is arranged below the protrusion 6. It is possible that the locking element 30 and the further locking element 40 can be arranged around the neck in the region of the groove 7 in order to lock the neck.

[0094] In order to carbonate the liquid in the bottle 2, a gas supply device 53 protrudes from above into the bottle 2. CO2 can reach the bottle 2 from the gas cartridge via the gas supply device 53 during carbonation. As a result, an overpressure is formed in the inner chamber 3 of the bottle 2. The inner chamber 3 of the bottle 2 is connected to the pressure chamber 51 via a gas connection 52. The gas connection 52 leads through a sealing device 50, which is provided for sealing the bottle 2 during carbonation. The overpressure built up in the inner chamber 3 of the bottle 2 during carbonation is transferred to the pressure chamber 51 via the gas connection 52, so that an overpressure is also generated in the pressure chamber 51. This overpressure in the pressure chamber 51 presses the sealing device 50 downward onto the mouth area of ​​the bottle 2. The projection 6 of the bottle 2 is thus firmly pressed onto the locking element 30 and the other locking element 40 and securely fixes the bottle 2. The sealing device 50 can be made, for example, of silicone.

[0095] Therefore, in Figure 8 and Fig. 9 In FIG. 1 , a gap 101 is illustrated, which the bottle 2 can have in the fastened position, in particular outside the carbonation process.

[0096] exist Fig.10 A perspective view of a counter-guide element 13 according to one embodiment of the invention is shown in . The counter-guide element 13 comprises a counter-guide means 11 and a further counter-guide means 12 which are designed as a guide rail 11 ′ and a further guide rail 12 ′.

[0097] exist Fig.11 , a perspective view of a locking element 30 according to an embodiment of the present invention is shown. The locking element 30 comprises a clamp 32 having a circular arc shape, so that the clamp 32 can be arranged around the bottleneck in the circumferential direction. In addition, the locking element 30 comprises a guide means 31 configured as a pin 31 ′. The guide means 31 is preferably configured in one piece with the rest of the locking element 30, thereby enabling high stability. The locking element 30 can be pivoted about the locking element axis 30 ′ and can thus perform a locking movement from a radially outer position to a radially inner position, which is indicated by the arrow. The locking element 30 can be guided in the guide rail 11 ′ of the counter-guide element 13 by the pin 31 ′.

[0098] exist Fig.12, a stereoscopic view of an additional locking element 40 according to an embodiment of the present invention is shown. The additional locking element 40 is preferably constructed in a mirror image with the locking element 30. The additional locking element 40 comprises an additional clamp 42 having a circular arc shape, so that the additional clamp 42 can be arranged around the bottleneck in the circumferential direction. In addition, the additional locking element 40 comprises an additional guide means 41 configured as an additional pin 41 ′. The additional guide means 41 is preferably constructed in one piece with the remaining additional locking elements 40, thereby achieving high stability. The additional locking element 40 can be pivoted about the additional locking element axis 40 ′ and can thus perform a locking movement from a radially outer position to a radially inner position. The additional locking element 40 can be guided in the additional guide rail 12 ′ of the counter-guide element 13 by the additional pin 41 ′.

[0099] The counter-guide element 13, the locking element 30 and the further locking element 40 are, for example, plastic parts. However, as an additional or alternative, materials other than plastic are also conceivable.
