Description

State of the art

[0001] The present invention relates to a receiving device for receiving a bottle on a carbonation machine, wherein the receiving device can be transformed from a bottle receiving state, which is provided for receiving the bottle, into an attachment state in which the bottle is attached to the receiving device.

[0002] Such devices are commonly known as components of carbonation machines designed to carbonate liquids, such as water. These machines are also frequently referred to as sparkling water makers and are used as household appliances by consumers. In principle, carbonation machines can be used to carbonate various liquids and prepare different beverages. For carbonation, the machines typically have a replaceable CO₂ cartridge that supplies the gas with which the liquid is carbonated. The liquid to be carbonated is typically filled into a bottle. The bottle containing the liquid is then attached to the carbonation machine to carry out the carbonation process.

[0003] From EP 3 040 114 B1 a carbonation machine for domestic use is known, comprising a carbonation assembly for carbonating liquid in a bottle with pressurized gas from a filling container, and a prong clamp for attaching the bottle to the carbonation machine.

[0004] WO 2015 / 021498 A1 discloses a receiving device for holding a bottle for a carbonation machine. Further receiving devices for holding a bottle for a carbonation machine are known from WO 2013 / 021361 A1, which discloses a carbonation machine according to the preamble of claim 1, and US 2025 / 367296 A1.

[0005] An important aspect is that the bottle must be securely and stably attached to the machine, as increased pressure is present during carbonation. To reliably withstand this pressure and prevent the bottle from unintentionally detaching from the machine, a correspondingly reliable and stable connection between the bottle and the machine must be established. At the same time, the connection must be user-friendly and easy to detach after carbonation and ideally designed for a high number of carbonation cycles over its lifespan. Disclosure of the invention

[0006] It is an object of the present invention to provide a receiving device for receiving a bottle on a carbonation machine, which enables a user-friendly and at the same time safe and stable attachment of the bottle to the carbonation machine.

[0007] This problem is solved by a receiving device according to claim 1. The receiving device according to the invention for holding a bottle on a carbonation machine has the advantage over the prior art that a fastening device with a locking element is provided, wherein the locking element has a guide means. It is advantageously possible for the locking element to be guided by its guide means during the transition of the receiving device from the bottle receiving state to the attachment state in such a way that the bottle is fastened to the receiving device by means of the locking element in such a way that the bottle can no longer escape downwards from the receiving device. This enables a user-friendly and at the same time secure fixation of the bottle.It is possible that the bottle still has some play even when installed, and in particular that it can still move in a direction parallel to its central axis over a certain range. However, the bottle preferably cannot be removed from the receiving device when installed, so that the bottle's play is limited, especially downwards. It is therefore particularly conceivable that, when installed, the bottle is attached to the receiving device with some play by the fastening device, and especially with the aid of the locking element, but is no longer removable and is secured against unintentional detachment from the receiving device.

[0008] According to the invention, the guiding element of the locking mechanism advantageously allows the locking element to be automatically guided radially inwards towards the bottle when the receiving device is moved from the bottle-holding state to the attachment state, thus fixing or securing the bottle in such a way that it can no longer escape downwards from the receiving device. This enables the bottle to be securely attached to the receiving device using the locking element, even under the high pressure during carbonation. At the same time, a particularly high level of user convenience is achieved, since the bottle is automatically secured when the receiving device is moved from the bottle-holding state to the attachment state, in particular without the need to operate a separate mechanism or trigger (e.g., a button) for this purpose.Furthermore, no motor or similar device is required for fixing and securely fastening the bottle, thus reducing the potential for errors and lowering costs. Additionally, according to the invention, the bottle does not need to be laboriously screwed into the carbonation machine. Therefore, it is advantageously possible, according to the invention, to dispense with a screw connection between the bottle and the carbonation machine.

[0009] Furthermore, because the locking element has a guide element, a particularly high stability of the locking element can be achieved, so that the locking element has a long service life on the one hand and is insensitive to damage on the other.

[0010] According to the invention, it is conceivable that the bottle, during the transition of the receiving device from the bottle receiving state to the mounting state, performs a tilting movement, thereby transitioning the bottle from a receiving position, particularly an inclined one (in the receiving state), to a preparation position, particularly a vertical one (in the mounting state). According to the invention, it is possible that the fastening of the bottle by means of the fastening device preferably occurs during the tilting movement of the bottle from its receiving position, particularly an inclined one (in the receiving state), to its preparation position, particularly a vertical one. In the preparation position, the bottle preferably still has some play within the receiving device. However, in the preparation position, the fastening device prevents the bottle from leaving the receiving device.

[0011] In the bottle receiving state of the receiving device, the bottle can be picked up by the receiving device from the carbonation machine, in particular inserted into the carbonation machine by a user.

[0012] According to the invention, it is conceivable that the transfer of the receiving device from the bottle receiving state to the attachment state is achieved by the tilting movement of the bottle. This tilting movement can, for example, be initiated by a user who moves the bottle from the receiving position to the preparation position. Alternatively or additionally, it is possible for the bottle to perform the tilting movement from the receiving position to the preparation position (particularly after the bottle has been received in the carbonation machine using the receiving device) automatically, and especially without any additional effort from the user, due to gravity.Alternatively or additionally, it is conceivable that the carbonation machine and in particular the receiving device for receiving the bottle is subjected to a spring force, whereby the spring force causes and / or supports the tilting movement of the bottle (in particular after the bottle has been introduced into the carbonation machine in the bottle receiving state).

[0013] According to the present invention, it is conceivable that, in the bottle receiving state, particularly during the initial picking up or insertion of the bottle, the bottle is not yet secured to the carbonation machine or to the bottle receiving device. It is therefore particularly advantageous that the bottle does not need to be separately secured when being picked up in the bottle receiving state. Thus, for example, screwing the bottle into the carbonation machine can be dispensed with. The securing / fixing of the bottle advantageously only occurs when the receiving device is moved from the bottle receiving state to the insertion state, particularly automatically, which increases user convenience and simplifies operation.

[0014] Typically, the intended carbonation of the liquid in the bottle requires a secure fixation of the bottle that can withstand the high pressure occurring during carbonation without the bottle detaching from the carbonation machine. According to the invention, such a secure fixation of the bottle can occur during the transition of the receiving device from the bottle-holding state to the mounting state, i.e., specifically only after the bottle has been received by the receiving device in the bottle-holding state. According to the invention, such fixation of the bottle can be particularly advantageously achieved using the fastening device and, in particular, using the locking element and its guide.When the bottle is received by the carbonation machine in the bottle receiving state, the fastening device is preferably in an open position in which it does not yet secure the bottle. During the transition of the receiving device from the bottle receiving state to the attachment state, the fastening device, and in particular the locking element, is then automatically moved by the guide into a fastening position in which the locking element secures the bottle, preferably with some play, or prevents the bottle from being removed from the receiving device.

[0015] According to the invention, it is preferably conceivable that the carbonation machine and the receiving device for receiving a bottle are provided on a carbonation machine for home use.

[0016] The bottle is preferably made entirely or partially of glass. Alternatively or additionally, it is conceivable that the bottle contains plastic and / or metal.

[0017] Using the inventive device for holding a bottle on a carbonation machine, the bottle can be connected to the carbonation machine in a reversible manner. The bottle can therefore preferably be detached from the carbonation machine after the carbonation process has been completed.

[0018] The bottle is preferably designed to withstand an internal pressure higher than the normal ambient pressure (approximately 1 bar). For example, it is conceivable that the bottle is designed to withstand an internal pressure of up to 11 bar, preferably up to 15 bar, more preferably up to 20 bar, 25 bar, or 30 bar, without bursting (at a temperature of 20°C and an external pressure of 1 bar).

[0019] The carbonation machine is preferably equipped with a replaceable gas cartridge, in particular a CO₂ cartridge, which provides the 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 inserted into the holding device.

[0020] The liquid used for carbonation can be, for example, water or a flavored beverage.

[0021] Advantageous embodiments and further developments of the invention can be found in the dependent claims and the description with reference to the drawings.

[0022] According to a preferred embodiment of the present invention, the receiving device comprises a counter-guiding element, in particular a counter-guiding element complementary to the guiding element, wherein the receiving device is configured such that, during the transition of the receiving device from the bottle receiving state to the mounting state, the locking element is guided by the guiding element and the counter-guiding element in such a way that the bottle is secured by means of the locking element. The counter-guiding element is in particular part of a counter-guiding element, which is a separate element or component of the receiving device from the locking element. Preferably, the counter-guiding element does not participate in the tilting movement of the bottle and the locking element during the transition of the receiving device from the bottle receiving state to the mounting state.The counter-guiding element preferably remains immovably in a fixed position during the transition of the receiving device from the bottle-holding state to the mounting state. The locking element, therefore, performs a relative movement to the counter-guiding element during this transition. During this relative movement, the guide and counter-guiding elements preferably force the locking element into a locking motion, guiding it radially inwards and securing the bottle to the receiving device. This allows for a particularly advantageous automatic fastening of the bottle to the receiving device.

[0023] According to the present invention, the locking element is pivotable about a locking element axis. In the bottle-receiving state, the locking element is arranged in a radially outer position. When the receiving device is moved from the bottle-receiving state to the mounting state, the locking element is pivoted about its locking element axis from its radially outer position to a radially inner position. The radially inner position is provided for securing the bottle. The locking element is thus pivotable about a locking element axis and can perform a locking movement from a radially outer position to a radially inner position to fix and / or secure the bottle. The locking element axis about which the locking element is pivotable preferably extends through an end region of the locking element.It is particularly conceivable that the locking element extends in a U-shape from this locking element axis.

[0024] According to a preferred embodiment of the present invention, the guide means, and in particular the counter-guide means, are designed such that the locking element is pivoted by the guide means, and in particular the counter-guide means, from its radially outer position to its radially inner position when the receiving device is moved from the bottle receiving state to the mounting state. During the transition of the receiving device from the bottle receiving state to the mounting state, the bottle and at least a part of the receiving device perform a tilting movement, by which the bottle is moved from an inclined receiving position to a, in particular, vertical mounting or preparation position. Preferably, the locking element performs the tilting movement together with the bottle and is, in particular, moved along with the bottle during its tilting movement.This tilting movement of the locking element advantageously causes the guide means to be moved by the counter-guide means in such a way that the locking element is forced during this tilting movement into an additional locking movement about a locking element axis, in particular from a radially outer to a radially inner position of the locking element. Through this locking movement, the locking element is moved towards the bottle and assumes a position in which it helps to secure the bottle (i.e., in particular to prevent the bottle from slipping out of the receiving device). This advantageously secures the bottle automatically as it executes its tilting movement from its inclined receiving position to its, in particular, vertical, preparation position.In particular, the bottle is secured in such a way that it does not detach from the carbonation machine even under high pressure during the subsequent carbonation process, and especially that it is not pushed downwards out of the receiving device.

[0025] According to a preferred embodiment of the present invention, the guide means and / or the counter-guide means comprises a detent means, wherein the locking element can be engaged in its radially inner position and / or in its outer position by means of the detent means. The detent means can, for example, comprise one or more detent grooves in the counter-guide means into which a projection, pin, and / or bolt of the guide means can be engaged. For example, a first detent groove in the counter-guide means can be arranged such that the projection, pin, and / or bolt of the guide means engages in this first detent groove in the radially outer position of the locking element, and / or a second detent groove in the counter-guide means can be arranged such that the projection, pin, and / or bolt of the guide means engages in this second detent groove in the radially inner position of the locking element.Other locking mechanisms, such as one or more locking ridges or one or more undercuts, are also conceivable. It is conceivable that the guide and counter-guide have mutually complementary locking mechanisms, so that the locking element can be engaged in its radially inner position, i.e., in particular when the fastening device is in the fixed position, and / or its radially outer position, i.e., in particular when the fastening device is open.

[0026] According to one of the present inventions, the fastening device comprises a further locking element, wherein the further locking element has a further guide means, wherein the receiving device is arranged such that when the receiving device is transferred 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 additionally fastened by means of the further locking element.

[0027] According to a preferred embodiment of the present invention, the receiving device comprises a further counter-guiding element, in particular a further counter-guiding element complementary to the further guide element, wherein the receiving device is configured such that, during the transition of the receiving device from the bottle receiving state to the mounting state, the further locking element is guided by the further guide element and the further counter-guiding element in such a way that the bottle is secured by means of the further locking element. It is preferably conceivable that the further counter-guiding element is part of the counter-guiding element, which also comprises the counter-guiding element.Preferably, the counter-guiding element does not participate in the tilting movement of the bottle, the locking element, and the further locking element during the transition of the receiving device from the bottle receiving state to the mounting state. Thus, the further locking element performs a relative movement to the counter-guiding element during the transition of the receiving device from the bottle receiving state to the mounting state. During this relative movement, the further guide and the further counter-guiding element force the further locking element into a locking movement, in which it is guided radially inwards and, in particular, secures the bottle in the receiving device.

[0028] Alternatively, it is conceivable that further counter-guiding means are part of a further counter-guiding element separate from the counter-guiding element. In this embodiment of the present invention as well, the further counter-guiding element preferably does not participate in the tilting movement of the bottle, the locking element, and the further locking element when the receiving device is moved from the bottle-receiving state to the mounting state. Thus, the further locking element performs a relative movement to the further counter-guiding element during the transfer of the receiving device from the bottle-receiving state to the mounting state. During this relative movement, the further guide and the further counter-guiding means force the further locking element into a locking movement, in which it is guided radially inwards and, in particular, secures the bottle in the receiving device.

[0029] According to one embodiment of the present invention, it is conceivable that the further guide means and / or the further counter-guide means comprises a further locking means, wherein the further locking element can be engaged in its radially inner position and / or in its radially outer position by means of the further locking means. Thus, it is possible for the further locking element to be engaged in its radially outer position and / or for the further locking element to be engaged in its radially inner position. The further locking means can, for example, comprise one or more locking grooves in the further counter-guide means into which a further projection, further pin, and / or further bolts of the further guide means can be engaged.For example, a first additional detent groove in the further counter-guiding element can be arranged such that the further projection, further pin and / or further bolts of the further guide element engage in this first additional detent groove in the radially outer position of the further locking element, and / or a second additional detent groove in the further counter-guiding element can be arranged such that the further projection, further pin and / or further bolts of the further guide element engage in this second additional detent groove in the radially inner position of the further locking element. Other additional detent means, such as one or more detent ridges or one or more undercuts, are also conceivable.It is conceivable that the further guide means and the further counter-guide means have complementary further locking means, so that the further locking element can be locked in its radially inner position, i.e., in particular in the fastening state of the fastening device, and / or its radially outer position, i.e., in particular in the open state of the fastening device.

[0030] According to one of the present inventions, the further locking element is pivotable about a further locking element axis, wherein the further locking element is arranged in a radially outer position in the bottle receiving state, and wherein, when the receiving device is moved from the bottle receiving state to the mounting state, the further locking element is pivoted about its further locking element axis from its radially outer position to 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 for the further locking element axis of the further locking element to run parallel to the locking element axis of the locking element. It is conceivable that the locking element axis and / or the further locking element axis run parallel to the central axis of the bottle.It is particularly conceivable that the locking element axis and / or the further locking element axis are designed parallel to the central axis of the bottle both in the bottle-receiving state of the receiving device (when the bottle is already inserted into the receiving device) and in the preparation state of the receiving device. It is particularly conceivable that the locking element axis and / or the further locking element axis tilt parallel to the central axis of the bottle during the tilting movement of the bottle (during the transition of the receiving device from the bottle-receiving state to the attachment state).

[0031] According to a preferred embodiment of the present invention, the further guiding means, and in particular the further counter-guiding means, are designed such that the further locking element is pivoted from its radially outer position to its radially inner position by the further guiding means, and in particular the further counter-guiding means, when the receiving device is transferred from the bottle receiving state to the mounting state.It is preferably possible that the further locking element, when the receiving device is moved from the bottle receiving state to the mounting state, performs a tilting movement together with the bottle, wherein the further guiding means is guided by the further counter-guiding means during this tilting movement in such a way that the further locking element is pivoted about its further locking element axis from its radially outer position to its radially inner position and thus contributes to fixing the bottle and in particular prevents the bottle from escaping downwards from the receiving device.

[0032] According to one embodiment of the present invention, it is conceivable that the locking element and the further locking element – ​​when the receiving device is moved from the bottle receiving state to the mounting state – are either both pivoted clockwise or both counterclockwise about their locking element axes. The locking element and the further locking element thus pivot, in particular, in the same direction of rotation.

[0033] According to an alternative embodiment of the present invention, it is conceivable that - during the transition of the receiving device from the bottle receiving state to the mounting state -: -- the locking element is pivoted counterclockwise about its locking element axis, and the further locking element is pivoted clockwise about its further locking element axis; or -- 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. The locking element and the further locking element thus pivot, in particular, in opposite directions.

[0034] According to one embodiment of the present invention, it is conceivable that the fastening device is designed with exactly two locking elements, in particular the locking element and the further locking element. According to an alternative embodiment of the present 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 designed in accordance with the locking element.It is conceivable that all locking elements of the fastening device – when the receiving device is moved from the bottle-holding state to the mounting state – are each moved from their radially outer positions to their radially inner positions, with the radially inner positions preferably being used to secure the bottle in the receiving device. It is conceivable that – when the receiving device is moved from the bottle-holding state to the mounting state – all locking elements are pivoted in the same direction of rotation, i.e., in particular, all clockwise or all counterclockwise. Alternatively, it is conceivable that – when the receiving device is moved from the bottle-holding state to the mounting state – the locking elements are pivoted partly clockwise and partly counterclockwise.

[0035] According to a preferred embodiment of the present invention, the bottle can be positioned on the receiving device in a receiving position, particularly a non-vertical one, while the flanges are arranged in a preparation position, particularly a vertical one. The receiving position or orientation, particularly a non-vertical or inclined one, and the preparation position or orientation of the bottle, particularly a vertical one, refer, for example, to the orientation of the bottle's central axis relative to a surface on which the carbonation machine is located. Thus, in a vertical preparation position, the bottle is, for example, arranged perpendicular to a surface, and in a non-vertical receiving position, it is tilted compared to the vertical preparation position.

[0036] According to a preferred embodiment of the present invention, the bottle undergoes a tilting movement during the transition of the receiving device from the bottle receiving state to the mounting state, moving from the (particularly non-vertical) receiving position to the (particularly vertical) preparation position. Preferably, during the transition from the bottle receiving state to the mounting state, the receiving device for holding the bottle is pivoted or tilted, at least partially, together with the bottle, such that the bottle is moved from a non-vertical receiving position to a vertical preparation position. Preferably, however, not all elements of the receiving device are tilted or moved in this process.For example, it is conceivable that a counter-guiding means, further counter-guiding means and / or counter-guiding element of the receiving device is not moved and tilted, but remains immobile in its position on the carbonization machine.

[0037] Alternatively, it is conceivable that the bottle, in its mounting position, is arranged in a non-vertical preparation position, such that its central axis is, for example, angled to the surface normal of a surface on which the carbonation machine is located. In this case, it is conceivable that the carbonation is carried out with the bottle in a non-vertical preparation position. However, even in this case, the bottle attached to the receiving device is preferably tilted or its angle to the surface changes when being transferred from the bottle receiving position to the mounting position. As a result, the bottle and the receiving device designed to hold the bottle undergo at least a partial tilting or rotational movement during the transfer from the bottle receiving position to the mounting position.

[0038] According to a preferred embodiment of the present invention, the guide means has a projection, pin and / or bolt, wherein preferably the further guide means has a further projection, further pin and / or further bolt.

[0039] According to a preferred embodiment of the present invention, the counter-guiding means has a rail, in particular a recess and / or depression, for guiding the guide means, and preferably the further counter-guiding means has a further rail, in particular a further recess and / or depression, for guiding the further guide means. This allows for a particularly advantageous automatic fixing of the bottle.

[0040] Alternatively, the guide means may have a rail, in particular a recess and / or depression, and preferably the further guide means may have a further rail, in particular a further recess and / or depression. In this case, the counter-guide means preferably has a projection, pin, and / or bolt that engages in the rail of the guide means and is guided therein. Accordingly, the further counter-guide means preferably has a further projection, pin, and / or bolt that engages in the further rail of the further guide means and is guided therein. Combinations are also conceivable.For example, it is possible that the guiding means has a projection, pin and / or bolt and the counter-guiding means has a rail complementary to it, wherein the further guiding means has a rail and the further counter-guiding means has a further projection, pin and / or bolt complementary to it.

[0041] According to a preferred embodiment of the present invention, the locking element comprises a shackle, in particular having a circular arc section, wherein the locking element secures the bottle by means of its shackle in the installed state, wherein preferably the further locking element comprises a further shackle, in particular having a further circular arc section, wherein the further locking element secures the bottle by means of its further shackle in the installed state. The shackles can thus advantageously be guided from the outside towards the bottle neck during the locking movement and thereby fix the bottle or secure it to the receiving device, in particular with some play. The shackles preferably extend perpendicular to the central axis of the bottle and / or such that they can be arranged circumferentially around or grip the bottle neck.

[0042] According to one embodiment of the present invention, it is particularly advantageous for the bottle to have a circumferential groove into which the locking element and / or the further locking element, in particular the bail and / or the further bail, can engage. The groove of the bottle is preferably a groove that extends completely around the neck of the bottle, so that the bottle does not have to be inserted into the carbonation machine at a predetermined angle of rotation.

[0043] Additionally or alternatively, according to one embodiment of the present invention, the bottle may have a circumferential projection and / or ridge which, in the installed state, is located particularly above the locking element and / or the further locking element, especially the clamp and / or the further clamp. The projection and / or ridge advantageously prevents the bottle from being forced downwards out of the fastening device by the pressure generated during the carbonation process. It is conceivable that the projection and / or ridge extends completely circumferentially around the bottle neck or, alternatively, only over a partial area and / or in sections. In the installed state, the locking element and preferably the further locking element engage around the bottle neck, particularly below the projection and / or ridge of the bottle neck.The projection and / or ridge of the bottle neck can thus rest on the locking element and preferably on the further locking element in the installed state, thereby particularly advantageously preventing the bottle from escaping downwards from the receiving device. According to one embodiment of the present invention, it is conceivable that the groove is arranged below the projection and / or ridge of the bottle neck, particularly preferably directly adjacent to the projection and / or ridge. Alternatively, it is conceivable that the bottle neck has only either such a groove or a projection and / or ridge.

[0044] Alternatively or additionally, it is conceivable that the locking element and preferably the further locking element, in the installed state, engage around a projection and / or ridge of the bottle neck, wherein the projection and / or ridge of the bottle neck is at least partially enclosed by the locking element and preferably the further locking element.

[0045] According to a preferred embodiment of the present invention, the bracket, in particular the circular arc section, spans an angular range of at least 45°, preferably at least 90°, and more preferably at least 170°. It is also preferably conceivable that the further bracket, in particular the further circular arc section, spans an angular range of at least 45°, preferably at least 90°, and more preferably at least 170°.

[0046] According to a preferred embodiment of the present invention, the locking element and its guide means are formed in one piece, and preferably the further locking element and its further guide means are also formed in one piece. The locking element and the further locking element are preferably separate parts.

[0047] According to a preferred embodiment of the present invention, the locking element is made of plastic, and preferably the further locking element is also made of plastic. It is therefore possible for both the locking element and the further locking element to be made of plastic. It is also conceivable that the locking element and the further locking element may additionally or alternatively comprise other materials, for example, one or more metals.

[0048] According to a preferred embodiment of the present invention, the receiving device has a cover element, wherein the locking element and / or the further locking element are preferably arranged behind the cover element, in particular such that the cover element at least partially conceals the locking element and / or the further locking element. According to a preferred embodiment of the present invention, the bottle has a collar, in particular a collar that fully, partially, or sectionarily encircles the bottle neck. When a user inserts the bottle into the receiving device, particularly in the bottle-receiving state of the receiving device, the insertion depth of the bottle into the receiving device is limited, in particular, by the cover element and the collar of the bottle.The bottle can only be inserted to the point where its collar, particularly from below, abuts the cladding element. The cladding element and the bottle's collar thus define and / or limit the insertion depth of the bottle within the holding device. This allows the user to conveniently and consistently position the bottle within the holding device.

[0049] Another object of the present invention is a carbonation machine comprising a receiving device for receiving a bottle according to an embodiment of the present invention.

[0050] According to a preferred embodiment of the present invention, particularly the carbonation machine, the carbonation machine comprises a safety element, in particular a safety door and / or safety screen, wherein the safety element, when installed, can be positioned in front of the bottle such that the bottle is, in particular, fully enclosed within the carbonation machine by means of the safety element. The safety element thus protects the surroundings of the carbonation machine and, in particular, a 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 could burst or shatter due to the high pressure during carbonation. However, because the safety element is positioned in front of the bottle during carbonation, it protects the surroundings and the user.The safety element can, for example, comprise safety glass and / or another material, such as metal and / or plastic, that withstands a shattering / exploding bottle or provides protection against bottle fragments. It is conceivable that the safety element is automatically positioned in front of the bottle when the receiving device is moved from the bottle-holding position to the mounting position, for example, by being slid in front of the bottle, or that a user positions the safety element in front of the bottle. Closing the safety element using an actuating element, such as a button, is also conceivable. For example, the safety element could be a sliding door that closes automatically due to the tilting motion of the bottle when the receiving device is moved from the bottle-holding position to the mounting position.

[0051] According to a preferred embodiment of the present invention, particularly the carbonation machine, the carbonation machine comprises a sealing means for sealing the bottle against the environment during carbonation, wherein the sealing means, in particular, seals the bottle against the environment during carbonation by means of pressure provided by a gas cartridge. This achieves pneumatic compensation. The gas cartridge is, in particular, the gas cartridge that provides the gas for carbonating the liquid. It is thus advantageously possible for the sealing of the bottle against the environment to be effected by actuating an actuating means to start the carbonation process, for example, a button or touchpad.The gas pressure provided by the gas cartridge (during carbonation) is therefore particularly advantageously used to seal the bottle to the outside during carbonation.

[0052] According to one embodiment of the present invention, a gas supply element projects into the bottle during installation and, in particular, during carbonation. The gas cartridge is connected to the gas supply element, so that during carbonation, the gas from the cartridge is introduced into the bottle via the gas supply element to carbonate the liquid. The gas supply element is guided, in particular, through a through-opening in the sealing element and thus projects into the bottle. The gas pressure provided by the gas cartridge (during carbonation) is preferably also used to press the sealing element against the bottle and thus seal the bottle externally during carbonation. In this way, advantageous carbonation of the liquid in the bottle can take place via the gas supply element projecting into the bottle.

[0053] According to one embodiment of the present invention, the sealing element may extend radially beyond the bottle neck or the bottle opening, so that when pressed against the bottle opening by the pressure provided by the gas cartridge, it reliably seals it to the outside. The sealing element preferably has a through-opening, particularly in the center, for the passage of the gas supply element, allowing the gas supply element to project through the sealing element into the interior of the bottle. It is conceivable that the sealing element is at least partially elastic to achieve an advantageous seal when pressed against the bottle or the bottle opening.In particular, an elastic or partially elastic sealing agent can be used to advantageously compensate for tolerances in the bottle, especially unevenness at the bottle neck, while still ensuring a seal. The sealing agent preferably comprises silicone. It is possible that the pressure with which the sealing agent is pressed against the bottle opening during carbonation fixes the bottle in a secure position. Specifically, it is conceivable that a protrusion and / or ridge of the bottle neck is pressed against the locking element and / or further locking elements by the pressure exerted on the bottle by the sealing agent. Thus, the bottle is clamped by the sealing agent and the locking element and / or further locking elements.

[0054] According to one embodiment of the present invention, the carbonation machine may include a pressure chamber, the pressure chamber being located adjacent to the sealing element. The pressure chamber and the sealing element thus enable advantageous automatic sealing of the bottle from the environment. In particular, it is possible for the sealing of the bottle from the environment to occur automatically as soon as the carbonation process is started and the gas cartridge is opened. It is advantageously conceivable that the locking element, and preferably the further locking element, secure the bottle in such a way that it remains securely fastened in the carbonation machine despite the overpressure generated in the pressure chamber (during carbonation) and / or the pressure exerted on the bottle by the sealing element, and in particular is not forced downwards out of the carbonation machine.

[0055] According to one embodiment of the present invention, it is conceivable that the pressure chamber, particularly during carbonation, is connected to the interior of the bottle via a gas connection, preferably such that an overpressure provided by the gas cartridge is generated in the pressure chamber during carbonation, wherein the sealing element is pressed against the bottle by the overpressure in the pressure chamber, particularly in such a way that it seals the bottle against the environment. The gas connection between the interior of the bottle and the pressure chamber is preferably designed as a channel, particularly as a channel formed by means of the sealing element. A gas connection between the interior of the bottle and the pressure chamber is established through the channel. If an overpressure is now generated in the bottle during carbonation by opening the gas cartridge, the gas connection creates a pressure in the cylinder.The channel also creates an overpressure in the pressure chamber. This overpressure is therefore particularly advantageously generated using the gas cartridge. This overpressure in the pressure chamber preferably causes the sealing material to be pressed downwards against the bottle, especially against the bottle's mouth area, which advantageously results in a seal between the bottle and the environment.

[0056] Another object of the present invention is a method for using a carbonization machine according to an embodiment of the present invention, wherein the method comprises the following steps: -- In a first step, the bottle is positioned in the bottle receiving state of the receiving device on the receiving device of the carbonation machine, wherein the bottle contains a liquid, -- in a second step, the receiving device is transferred from the bottle receiving state to the attachment state, wherein, during the transfer from the bottle receiving state to the attachment state, the locking element is guided by means of its guide such that the bottle is attached to the receiving device by means of the locking element, -- in a third step, the liquid in the bottle is carbonated.

[0057] It is possible that the receiving device will return to the bottle receiving state after carbonation, so that the bottle containing the carbonated liquid can be removed.

[0058] Preferably, the carbonation of the liquid in the third step is carried out using a gas cartridge that supplies a gas, in particular CO₂, for carbonating the liquid in the bottle via a gas supply device projecting into the interior of the bottle. Carbonation can be started, for example, by a user via an actuating element, particularly after the receiving device has reached the installed position and / or the bottle has been moved into the preparation position. Suitable actuating elements for starting carbonation include, for example, a push button, a switch, a touchpad, an acoustic signal, and / or other actuating elements. Alternatively, it is conceivable that carbonation starts automatically after the installed position has been reached and / or after a safety element, in particular a safety door and / or safety glass, has been closed.

[0059] According to a preferred embodiment of the present invention, in particular of the method, the fastening device comprises a further locking element, wherein the further locking element has a further guide means, wherein in the second step, when the receiving device is moved from the bottle receiving state to the mounting state, the further locking element is guided by means of its further guide means such that the bottle is fastened by means of the further locking element. Thus, preferably in the second step, the bottle is fastened to the receiving device by the locking element and the further locking element together, in particular such that the bottle can no longer be removed from the receiving device.The bottle can be attached to the receiving device with some play in the mounting position, meaning it can move within the receiving device parallel to its central axis (especially up and down). In its mounting or preparation position, the bottle can thus still move parallel to its central axis, although the mounting device prevents it from leaving the receiving device. It is conceivable that, after the user releases the bottle, gravity may cause it to move downwards within this play until its movement is restricted by the mounting device, particularly by the locking element and preferably by the additional locking element. The bottle thus remains securely in the carbonation machine in its mounting position.After the user releases the bottle, it is advantageous that gravity and the fastening device hold the bottle in a well-defined position. Specifically, the bottle's flange rests on the locking element and the additional locking element.

[0060] According to one embodiment of the present invention, it is conceivable that in the second step the bottle performs a tilting movement from a receiving position, particularly a non-vertical one, in which the bottle was arranged in the first step, to a preparation position, particularly a vertical one. Preferably, the receiving device for holding the bottle is tilted at least partially in the second step together with the bottle, such that the bottle is transferred from the receiving position to the preparation position. It is preferably possible that the bottle is fixed during this tilting movement in the second step by means of the locking element and preferably by means of the further locking element, particularly with some play. The tilting movement in the second step is caused in particular by the fact that the bottle automatically moves from the receiving position to the preparation position due to gravity.Alternatively or additionally, a user can move the bottle from the receiving position to the preparation position. Alternatively or additionally, the receiving device can be spring-loaded, in particular such that the bottle is automatically moved from the receiving position to the preparation position by means of the spring force in a second step.

[0061] According to one embodiment of the present invention, it is conceivable that, during the carbonation process in the third step, an overpressure is built up in the bottle using the gas cartridge to carbonate the liquid. Preferably, the overpressure built up in the bottle is transferred to the pressure chamber of the carbonation machine, in particular a pressure chamber of the receiving device, via a gas connection or channel between the interior of the bottle and the pressure chamber. Alternatively, a direct gas connection between the pressure chamber and the gas cartridge (during carbonation) would also be conceivable. The overpressure thus built up in the pressure chamber forces a sealing element arranged on the pressure chamber downwards towards the bottle.The sealing material presses the bottle downwards against the locking element in its secured position, and in particular against the further locking element, whereby the locking element and especially the further locking element limit downward movement of the bottle, in particular such that the sealing material and / or the overpressure prevent the bottle from being forced out of the receiving device. This advantageously ensures that the bottle remains in its preparation or secured position.

[0062] The advantages and features already described in connection with the inventive holding device for a bottle on a carbonation machine or in connection with an embodiment of the inventive holding device for a bottle on a carbonation machine can be applied to the carbonation machine according to the invention and the inventive method for using a carbonation machine.The advantages and features already described in connection with the inventive method for using a carbonation machine or in connection with an embodiment of the inventive method for using a carbonation machine can be applied to the inventive receiving device for receiving a bottle on a carbonation machine and the inventive carbonation machine.

[0063] Further details, features, and advantages of the invention will become apparent from the drawings and from the following description of preferred embodiments with reference to the drawings. The drawings merely illustrate exemplary embodiments of the invention, which do not limit the essential concept of the invention. Brief description of the drawings

Embodiments of the invention

[0065] In the various figures, identical parts are always marked with the same reference symbols and are therefore usually only named or mentioned once.

[0066] In Figure 1Figure 1 shows a perspective view of a carbonation machine 1 according to an exemplary embodiment of the present invention in a bottle-receiving state. The carbonation machine comprises a receiving device 10. In the bottle-receiving state of the receiving device 10, the bottle 2 can be arranged in a tilted, non-perpendicular receiving position on the carbonation machine 1. The central axis 2' of the bottle 2 is accordingly not arranged vertically, but runs obliquely. By a tilting movement 100, the bottle 2 can be moved from the receiving position into a preparation position, in particular a vertical one.

[0067] The tilting movement 100 of bottle 2 can, for example, be initiated by a user who moves bottle 2 from the receiving position to the preparation position. Alternatively or additionally, it is possible for bottle 2 to perform the tilting movement 100 from the receiving position to the preparation position automatically, and in particular without any additional effort from the user, due to gravity. Alternatively or additionally, it is conceivable that the carbonation machine 1, and in particular the receiving device 10, is subjected to a spring force, whereby the spring force causes and / or assists the tilting movement 100 of bottle 2.According to the invention, it is advantageously possible for a part of the receiving device 10 to perform the tilting movement 100 together with the bottle 2, whereby the receiving device 10 is transferred from the bottle receiving state to the mounting state of the receiving device 10, in which the bottle 2 is attached to the receiving device 10.

[0068] A gas cartridge can be inserted on the rear side 1' of the carbonation machine 1, which provides the gas for the carbonation of a liquid, in particular water, located in the bottle 2.

[0069] In Figure 2 is a perspective view of carbonization machine 1 according to the Figure 1 shown in an installed state, particularly after completion of the tilting movement 100. In this installed state, the bottle 2 is in the vertical mounting position or preparation position, so that carbonation is possible.

[0070] In Figure 3 Figure 1 shows a perspective view of a carbonation machine 1 according to an exemplary embodiment of the present invention. In particular, the installation state in which carbonation can be carried out is shown. The carbonation machine 1 comprises a safety element 60, in particular a safety door 61. In the installation state, the safety element 60 is arranged in front of the bottle 2 such that the bottle 2 is completely enclosed within the carbonation machine 1. The safety element 60 thus protects the user and the surroundings of the carbonation machine 1, for example, from the bottle 2 shattering. It is possible that the carbonation process can only be started when the safety element 60 is closed.

[0071] In Figure 4Figure 1 shows a perspective view of a receiving device 10 and the area surrounding the receiving device 1 of the carbonation machine 1 according to an exemplary embodiment of the present invention. The carbonation machine 1 comprises a gas supply means 53, which projects into the bottle 2 when the bottle 2 is installed. The receiving device 10 comprises a cover element 55. The cover element 55 conceals the locking element 30 and the further locking element 40 of the fastening device 20. A receiving part 57 of the receiving device 10 is also shown. The receiving part 57 comprises a recess into which the neck of the bottle 2 can be inserted. The receiving part 57 guides and positions the bottle 2 when it is inserted into the receiving device 10, thus facilitating the insertion process for the user and increasing user comfort.

[0072] In Figure 5Figure 1 shows a perspective view of a receiving device 10 and the area surrounding the receiving device 1 of the carbonization machine 1 according to an exemplary embodiment of the present invention. The cladding element 55 is hidden in the illustration so that the parts of the fastening device 20 behind it are visible. The fastening device 20 comprises a locking element 30 and a further locking element 40. The locking element 30 and the further locking element 40 are arranged in Figure 5shown in an open state, which they assume in the bottle-receiving state of the receiving device 10, so that the bottle 2 can be inserted. The locking element 30 comprises a lever 32 having a circular arc region and configured to engage circumferentially around the neck of the bottle 2. The further locking element 40 comprises a further lever 42 having a further circular arc region and also configured to engage circumferentially around the neck of the bottle 2. The locking element 30 is pivotable about a locking element axis 30', in particular from a radially outer position, which is located in the Figure 5 is shown in a radially inner position, which is in the Figure 6is shown and corresponds to a closed state of the fastening device 20. The further locking element 40 is pivotable about a further locking element axis 40', in particular from a radially outer position, which is shown in the Figure 5 is shown in a radially inner position, which is in the Figure 6 is shown and corresponds to a closed state of the fastening device 20.

[0073] The receiving device 10 further comprises a counter-guiding element 13. The counter-guiding element 13 comprises a counter-guiding means 11 and a further counter-guiding means 12. The counter-guiding means 11 is designed as a rail 11', in particular as a recess in the counter-guiding element 13. The pin 31' of the guide means 12 engages in this rail 11' and is guided by the rail 11'. The further counter-guiding means 12 is designed as a further rail 12', in particular as a further recess in the counter-guiding element 13. The further pin 41' of the further guide means 12 engages in the further rail 12' and is guided by the further rail 12'.

[0074] The counter-guide element 13 does not participate in the tilting movement 100 of the bottle 2 during the transition of the receiving device 10 from the bottle receiving state to the mounting state, but remains stationary on the carbonation machine 1. As a result, the locking element 30 and the further locking element 40 perform a relative movement relative to the counter-guide element 13 (and thus to the counter-guide means 11 and the further counter-guide means 12) during the transition of the receiving device 10 from the bottle receiving state to the mounting state. This relative movement moves the pin 31' in the rail 11', in particular from bottom to top. Due to the geometric design of the rail 11', the locking element 30 is forced into a locking movement 33, during which it pivots radially inwards towards the bottle 2.Accordingly, the relative movement causes the further pin 41' in the further rail 12' to move, in particular from bottom to top. The design of the further rail 12' forces the further locking element 40 into a locking movement, pivoting radially inwards towards the bottle 2. Thus, when the receiving device 10 is moved from the bottle receiving state to the mounting state, the locking element 30 and the further locking element 40 are automatically moved into a fastening position by the guide means 31 and the counter-guide means 11, respectively, by the further guide means 41 and the further counter-guide means 12. In this position, the locking element 30 and the further locking element 40 secure the bottle 2 in the receiving device 10, in particular with clearance 101, and prevent the bottle 2 from being removed from the receiving device 10.

[0075] In Figure 6 is a perspective representation of the in the Figure 5The illustrated receiving device 10 is shown in the mounting position. The locking element 30 and the further locking element 40 have accordingly completed their locking movements and are each in their radially inner positions, i.e., in their fastening positions. The locking element 30 secures the bottle 2 (not shown) in the mounting position by means of its bracket 32, which extends circumferentially around the bottle neck. The further locking element 40 secures the bottle 2 (not shown) in the mounting position by means of its further bracket 42, which extends circumferentially around the bottle neck. In the illustrated embodiment, the bracket 32 ​​spans an angular range of slightly less than 180°. Similarly, the further bracket 42 spans an angular range of slightly less than 180°.Together, the bail 32 and the further bail 42, in their radially inner position, can thus essentially completely enclose the bottle neck and prevent the bottle 2 from being unintentionally pushed out of the receiving device 10 during carbonation.

[0076] In Figure 7Figure 1 shows a sectional view of a carbonation machine 1 and a bottle 2 according to an exemplary embodiment of the present invention. The receiving device 10 is in the bottle-receiving state. The bottle 2 is inserted into the receiving device 10 in a tilted, non-perpendicular receiving position. The receiving device 10 comprises a receiving part 57 with a recess into which the neck of the bottle 2 is partially inserted. The receiving part 57 guides and positions the bottle 2 when it is inserted into the receiving device 10, thus facilitating the insertion process for the user and increasing user comfort. Typically, the user pushes the bottle 2 into the receiving device 10 from an oblique angle below, so that the bottle neck is guided into the receiving part 57.The insertion movement of the bottle 2 by the user is advantageously limited at the top by a collar 8 of the bottle 2 and the cladding element 55 of the receiving device 10. The collar 8 encircles the bottle neck completely or only partially. The bottle 2 can only be inserted into the receiving device 10 to the extent that the collar 8 of the bottle 2 abuts the cladding element 55 from below. The insertion depth of the bottle into the receiving device 10 is thus limited by the cladding element 55 and the collar 8 of the bottle 2. In this way, the bottle 2 can be positioned comfortably and reproducibly in a receiving position on the receiving device 10 by the user. As an alternative to the collar 8, a different type of widening or bulging of the bottle 2 would also be conceivable.The receiving part 57 and / or the casing part 55 have a chamfered guide, preferably circumferential, through which the bottle 2 is preferably received, guided, and positioned when inserted into the receiving device 10. The chamfered guide is designed such that the diameter of the opening of the receiving part 57 and / or the casing part that receives the bottle decreases in the insertion direction.

[0077] In the bottle intake state according to the Figure 7 The guide means 31, in particular the pin 31, of the locking element 30 is arranged at the bottom of the counter-guide means 11, in particular the rail 11', by means of the tilted orientation of the locking element 30. The same applies to the further guide means 41 of the further locking element 40, which is arranged at the bottom of the further counter-guide means 12, in particular the further rail 12'. During the transition from the bottle receiving state (see Figure 7 ) in the installed state (see Figure 8The pin 31' moves from bottom to top in the rail 11'. The design of the rail 11' forces the locking element 30 into a locking movement 33, pivoting radially inwards towards the bottle 2. Similarly, the relative movement causes the other pin 41' in the further rail 12' to move from bottom to top, forcing the other locking element 40 into a locking movement as well, pivoting radially inwards towards the bottle 2. Thus, the locking element 30 and the other locking element 40 are locked in place by the guide means 31 and the counter-guide means 11, respectively, during the transition of the receiving device 10 from the bottle receiving state to the mounting state.The further guide means 41 and the further counter-guide means 12 automatically move the bottle 2 into a fastening position in which the locking element 30 and the further locking element 40 secure the bottle 2 in the receiving device 10 and prevent its removal from the receiving device 10. The corresponding mounting state of the receiving device 10 is shown in the figure. Figure 8 The bottle 2 and the parts of the receiving device 10 that move during the tilting motion have been brought into a vertical position. In the Figure 8 The figure shows a state in which the user is still holding bottle 2 and may be pushing upwards. This maintains contact between collar 8 and the cover element 55.

[0078] In Figure 9The figure shows the installed state after the user has released the bottle 2. The bottle 2 moves downwards within the clearance 101 it has in the installed state until a projection 6 of the bottle 2 rests on the locking elements 30, 40, which are in the mounting position. Thus, the collar 8 no longer touches the cover element 55 and is spaced apart from it. The distance between the collar 8 and the cover element 55 depends in particular on the size of the clearance 101 that the bottle 2 has in its vertical mounting position in the installed state. In the illustrated embodiment, the projection 6 on the bottle neck has a rectangular cross-section and extends outwards from the bottle neck. Other shapes and configurations, in particular other cross-sectional geometries, are also conceivable for the projection 6.Preferably, the projection 6 extends completely around the neck of the bottle in the circumferential direction. Alternatively, it is conceivable that the projection 6 is formed only in sections, particularly with interruptions in the circumferential direction. The projection 6, the locking element 30, and the further locking element 40 secure the bottle to the receiving device in such a way that the bottle 2 cannot leave the receiving device 10 when attached, thus enabling reliable carbonation. The U-shaped locking elements 30, 40 and their arc segments create a particularly large contact area between the projection 6 and the locking elements 30, 40, resulting in particularly advantageous mechanical stability.

[0079] It is possible that the bottle 2 has a groove 7, in particular a groove 7 that extends completely around the bottle neck. The groove 7 is arranged below the projection 6. It is possible that the locking element 30 and the further locking element 40 can be arranged in the area of ​​the groove 7 around the bottle neck to lock the bottle neck.

[0080] For the carbonation of the liquid in bottle 2, a gas supply element 53 extends into bottle 2 from above. During carbonation, CO₂ can enter bottle 2 from a gas cartridge via the gas supply element 53. This creates overpressure in the interior 3 of bottle 2. The interior 3 of bottle 2 is connected to a pressure chamber 51 via a gas connection 52. The gas connection 52 is guided through a sealing element 50, which is used to seal bottle 2 during carbonation. The overpressure that builds up in the interior 3 of bottle 2 during carbonation is transmitted to the pressure chamber 51 via the gas connection 52, thus creating overpressure in the pressure chamber 51 as well. This overpressure in the pressure chamber 51 forces the sealing element 50 downwards onto the opening of bottle 2.The projection 6 of bottle 2 is thereby pressed firmly onto the locking element 30 and the further locking element 40, thus securely fixing bottle 2. The sealing material 50 can, for example, be made of silicone.

[0081] In the Figures 8 and 9 This clarifies the game 101 that bottle 2 may exhibit in the fixing position, especially outside the carbonation process.

[0082] In Figure 10 Figure 1 shows a perspective view of a counter-guiding element 13 according to an embodiment of the present invention. The counter-guiding element 13 comprises a counter-guiding means 11 and a further counter-guiding means 12, which are configured as rail 11' and further rail 12'.

[0083] In Figure 11Figure 1 shows a perspective view of a locking element 30 according to an embodiment of the present invention. The locking element 30 comprises a bracket 32 ​​with a circular arc shape, such that the bracket 32 ​​can be arranged circumferentially around a bottle neck. Furthermore, the locking element 30 comprises a guide element 31 designed as a pin 31'. The guide element 31 is preferably formed integrally with the rest of the locking element 30, thereby achieving high stability. The locking element 30 is pivotable about a locking element axis 30' and can thus perform a locking movement from a radially outer to a radially inner position, which is indicated by the arrow 33. The locking element 30 can be guided in the rail 11' of the counter-guide element 13 via the pin 31'.

[0084] In Figure 12Figure 1 shows a perspective view of a further locking element 40 according to an embodiment of the present invention. The further locking element 40 is preferably designed as a mirror image of the locking element 30. The further locking element 40 comprises a further bracket 42 with a circular arc shape, so that the further bracket 42 can be arranged circumferentially around a bottle neck. Furthermore, the further locking element 40 comprises a further guide element 41 designed as a further pin 41'. The further guide element 41 is preferably formed integrally with the rest of the further locking element 40, thereby achieving high stability. The further locking element 40 is pivotable about a further locking element axis 40' and can thus perform a locking movement from a radially outer to a radially inner position.The further locking element 40 can be guided in the further rail 12' of the counter-guiding element 13 via the further pin 41'.

[0085] The counter-guide element 13, the locking element 30, and the further locking element 40 are, for example, plastic parts. However, other materials besides plastic are also possible, either additionally or as an alternative. Reference symbol list
