Definitions
- the invention relates to a pressure vessel according to the features of the preamble of claim 1.
- a pressure vessel for holding physical propellants is known. At least one flavored physical propellant, which is in the form of a fluid and is suitable for consumption, is arranged in the pressure vessel.
- the invention is based on the object of specifying a pressure vessel that is improved compared to the prior art.
- a pressure vessel has a container body. At an upper end of the container body, an end region is formed in one piece with the container body. This end region, which is formed in one piece with the container body, can also be referred to as an end piece. The end region has a container opening. Furthermore, the container body has a container base arranged at a lower end and formed in one piece with the container body.
- the pressure vessel also has a valve which is arranged in and/or at the end region. The valve is screwed into the end area, for example. It is designed, for example, as a check valve.
- the container opening of the end area is closed media-tight by the valve.
- the valve in particular has a valve body with a passage opening in which a valve tappet is arranged, which closes the passage opening in a media-tight manner in a closed valve position of the valve and releases the passage opening in an open valve position of the valve.
- the pressure vessel has a suction pipe which is arranged in the interior of the pressure vessel and is firmly and fluid-tightly connected to the valve.
- a pipe interior of the suction pipe is fluidly connected to the passage opening of the valve.
- the suction pipe extends in the direction of the container base into an area of the container base and has a pipe opening in the area of the container base.
- the pipe opening is arranged in particular in a lower tenth of the container interior, in particular in a lower tenth of the height of the container interior.
- the pressure container in particular a compressed gas container, enables in particular a direct, media-tight coupling of the pressure container to a further connection, for example a connection of an application.
- a further connection for example a connection of an application.
- the valve tappet is moved into the open valve position by means of the application, for example by means of an actuation unit of the application.
- the medium from the interior of the container flows out of the pressure vessel via the passage opening and into the application.
- the pressure vessel is particularly advantageous for a medium intended for introduction into a beverage, which has a propellant, in particular a propellant gas, and a flavor.
- the blowing agent is in particular carbon dioxide (CO 2 ).
- the aroma in particular has at least one essential oil as a carrier.
- the medium is therefore a flavored leavening agent.
- the pressure container is filled with such a medium, it can be used in an application by means of which the medium, in particular the carbon dioxide and the aroma, can be introduced into the beverage, for example water.
- the application is therefore a device for simultaneously bubbling and flavoring the drink, for example water, and is therefore also referred to as a water bubbler or beverage bubbler.
- the pressure container is also referred to as a gas cartridge.
- the components of the medium i.e. H. the blowing agent, in particular carbon dioxide, and the aroma, for example, are mixed before the pressure vessel is filled and are filled together into the pressure vessel, or they only come together, for example, in the pressure vessel.
- the pressure container can also be filled one after the other with these components of the medium, for example first filling with the aroma and then with the propellant, in particular carbon dioxide.
- the medium with which the pressure container is then filled and which is then intended for introduction into a drink then contains the carbon dioxide and the aroma.
- the aroma is in the liquid state in the lower area of the interior of the container and is therefore mixed in particular with the liquid part of the propellant.
- the valve is opened, the propellant, which is already in a gaseous state, escapes from the upper area of the interior of the container, which is not optimally mixed with the aroma.
- the pressure vessel In order to achieve sufficient mixing of the entire propellant with the aroma, the pressure vessel would have to be heated above room temperature so that the aroma also evaporates and mixes with the propellant. However, this also increases the pressure inside the container, although this is only permissible up to a maximum pressure.
- the gaseous propellant and the aroma also separate again over time. For bubbling with an optimally mixed flavored propellant, it would be necessary to reheat and mix the propellant with the flavor before each bubbling process. However, this is not practical. The consequence of this is that the flavoring of drinks is not consistent. In addition, to ensure sufficient aromatization, a relatively large amount of aroma is required.
- the aroma collects on the bottom of the container after filling the pressure container with the propellant and the aroma or only mixes with the liquid supercritical part of the propellant, because by means of the suction pipe, the pipe opening of which is arranged in the area of the container base is, either the aroma or the aroma and the liquid supercritical propellant are sucked in from this area of the container bottom, gaseous during the rise in the suction pipe and discharged in the gaseous state through the valve from the interior of the container and introduced into the beverage.
- the suction tube is in particular designed in such a way that it sucks in liquid propellant and aroma, in particular mixes liquid propellant with aroma.
- this flavored propellant changes from the liquid to the gaseous state during the rising process up to the valve and then exits through the open valve into the application, ie into the beverage maker. This results in optimal fizzing and flavoring of the drink, for example water.
- the suction pipe as described, is firmly and tightly connected to the valve and designed in such a way that the liquid, in particular flavored, propellant sucked in from the area of the container base changes into the gaseous state as it rises.
- the suction pipe is designed in such a way that it always has the pipe opening in the area of the container bottom.
- the suction pipe is designed such that it sucks the propellant, which is in the gaseous state, from the upper region, in particular the upper third, of the container interior and, in particular through the Venturi effect,
- the aroma is sucked in via the pipe opening in the area of the container base, which also results in the optimal mixture of aroma and propellant and thus the optimally flavored propellant.
- the pipe opening is formed at a pipe end of the suction pipe and thus forms a pipe end opening.
- This is a particularly easy to manufacture embodiment of the suction pipe. If the pipe end is straight, i.e. i.e., if an opening cross section of the pipe opening is aligned perpendicular to the longitudinal axis of the suction pipe, the pipe end is arranged at a distance from the container base, but, as described, in the area of the container base. This ensures that the pipe opening is not blocked by the bottom of the container.
- the pipe end is designed obliquely, ie the opening cross section of the pipe opening runs obliquely to the longitudinal axis of the suction pipe. This ensures that even if the suction pipe extends to the bottom of the container, the pipe opening, which here is also at the end of the pipe is formed and thus forms the pipe end opening, is not closed by the container bottom.
- an end region of the suction pipe is funnel-shaped in the direction of the pipe end.
- the pipe opening located at the pipe end and thus forming the pipe end opening therefore has a smaller cross section than the other areas of the suction pipe. This achieves optimized suction of the aroma and/or the liquid propellant.
- the suction pipe is U-shaped, with the pipe end being arranged in an upper region of the container interior.
- the pipe opening which is arranged in the area of the container base, is therefore not formed at the pipe end, i.e. H.
- This pipe opening is not identical to the pipe end opening, but the pipe opening is formed in the lower region of the U-shape, in particular at the lowest point of the U-shape.
- the pipe end here also has the pipe end opening at the pipe end, thus in addition to the pipe opening.
- the valve when the valve is opened, the propellant, which is in the gaseous state, is sucked in from the upper area, in particular the upper third, of the container interior via the pipe end opening and, in particular due to the Venturi effect, the aroma is sucked in via the pipe opening in the area of the container bottom, which also means the optimal mixture of aroma and leavening agent and thereby the optimally flavored leavening agent is achieved.
- the pipe end and thus the pipe end opening is arranged in particular in an upper third of the container interior, in particular in an upper third of the height of the container interior.
- At least one wall opening is formed in a pipe wall of the suction pipe in an upper region of the suction pipe, for example in the form of a slot or a bore.
- the pipe opening is included in particular designed as a pipe end opening at the pipe end of the suction pipe.
- the pipe end mentioned, on which the pipe end opening is located, is always the free pipe end of the suction pipe that is spaced from the valve.
- a fastening structure for the valve is provided on the inside of a wall surrounding the container opening of the end region.
- it has an internal thread arranged on the inside of the wall.
- the valve i.e. H. in particular the valve body, has an external thread corresponding to the internal thread of the fastening structure.
- the valve When screwed into the internal thread, in particular completely, i.e. H. Up to a predetermined end position, screwed in state, the valve is arranged in the area of the container opening of the end area and protrudes from the container opening into the end area. In particular, it is media-tight at the end region.
- the container body in particular has a connection geometry arranged on the outside on a wall surrounding the container opening of the end region, for example an external thread, for example an ACME thread, or a latching arrangement or a quick-release fastener, the wall forming a connection with the connection geometry, which is set up with a corresponding further connection, in particular a connection of the application, to be or be coupled in a media-tight manner.
- a connection geometry arranged on the outside on a wall surrounding the container opening of the end region, for example an external thread, for example an ACME thread, or a latching arrangement or a quick-release fastener
- the pressure vessel has an overpressure safety device.
- this overpressure safety device is arranged in the valve.
- this overpressure safety device is arranged, for example, in the container base, in particular in an overpressure opening formed in the container base.
- this enables an integrated arrangement of the overpressure safety device without it protruding beyond an outer edge of the pressure container. This increases protection against mechanical damage to the overpressure safety device.
- a required installation space for accommodating the pressure vessel in the application can be reduced and assembly of the pressure vessel in the installation space is simplified.
- the overpressure protection includes, for example, a rupture disk.
- a rupture disk For example, an overpressure channel running through the valve tappet is formed, which is closed in a media-tight manner by the rupture disk.
- the rupture disk is arranged on the valve tappet at an end of the overpressure channel facing the interior of the container and is held on the valve tappet by the housing, for example.
- the rupture disk is secured, for example, with a screw comprising a vent bolt, for example in the valve or in the container base.
- the overpressure safety device is designed for a release pressure of 250 bar. However, any other trigger pressure values are also possible.
- the rupture disk is fluidly coupled to an interior of the pressure vessel, ie to the interior of the vessel.
- the pressure vessel ie to the interior of the vessel.
- it is held on the edge by the screw, within which a Vent bolt is designed or arranged, or held by the housing and the valve tappet with an overpressure channel formed therein. If the triggering pressure is exceeded, the rupture disk is mechanically destroyed and releases a fluidic connection between the vent bolt or the overpressure channel and the interior of the container, so that the medium located in the interior of the container, for example gas, can escape.
- the overpressure opening comprises, for example, an internal thread corresponding to an external thread of the screw, into which the screw is screwed.
- the internal thread is created by machining.
- the internal thread can also be produced in a forming process, for example a roll forming process, during the formation of the container base. Alternatively, other methods for producing the internal thread are also possible.
- the container body and the end region are, for example, produced together from a material blank in a roll forming process.
- a particularly high level of pressure stability is achieved with little effort, in particular with little material expenditure, since connections, for example weld seams, which represent weak points, are avoided.
- the fastening structure for the valve and in particular the connection geometry are produced, for example, by means of machining and/or forming, in particular during the roll forming process, and/or application of material and/or other suitable processes in the area of the end region.
- the valve with the suction pipe arranged on it is then attached to the end region in the area of the container opening, in particular screwed in.
- the pressure vessel can be produced particularly easily and with high quality using the roll forming process.
- the production of the fastening structure and the fastening of the valve are particularly simple, reliable and can be implemented at low cost.
- the overpressure opening is created in the container base by means of machining and/or forming, in particular during the roll forming process, and/or application of material and/or other suitable methods, and the overpressure safety device is then attached to the overpressure opening.
- the creation of the overpressure opening and the attachment of the overpressure safety device are particularly simple, reliable and can be implemented at low cost.

- the valve 6 also has a valve tappet 6.3.
- the valve tappet 6.3 is arranged in the passage opening DO and closes it in a media-tight manner in a closed valve position. In an open valve position, the valve tappet 6.3 releases the passage opening DO.
- valve tappet 6.3 For actuation in an application, the valve tappet 6.3 is moved downwards into the open valve position by means of the application, for example by means of an actuation unit of the application, whereby the passage opening DO is opened.

- the propellant T After filling, the propellant T is in a liquid supercritical state FZ in the lower two thirds of the container interior 8. Above this, it initially exists in a transition phase P between the liquid and gaseous state and then in the gaseous state GZ. After filling the pressure vessel 1, the aroma A collects on the container bottom 4 or only mixes with the liquid supercritical part of the propellant T.
- the suction pipe 9 is in particular designed in such a way that it sucks in liquid propellant T and flavor A, in particular liquid propellant T which is mixed with the flavor A.

- the pipe opening 10 is formed at a pipe end of the suction pipe 9 and thus forms a pipe end opening 11, as in the Figures 1 and 2 shown.
- This is a particularly easy to manufacture embodiment of the suction pipe 9. If the pipe end is straight, that is, if an opening cross section of the pipe opening 10 is aligned perpendicular to the longitudinal axis of the suction pipe 9, the pipe end is arranged at a distance from the container base 4, but, as described, in the area of the container bottom 4.

- the pipe end is designed obliquely, i.e. H. the opening cross section of the pipe opening 10 runs obliquely to the longitudinal axis of the suction pipe 9. This ensures, even if the suction pipe 9 extends to the container bottom 4, that the pipe opening 10, which is also formed here at the pipe end and thus forms the pipe end opening 11, is not closed by the container bottom 4.
- an end region of the suction pipe 9 is funnel-shaped in the direction of the pipe end, as in Figure 2 shown.
- the one located at the pipe end and thus forming the pipe end opening 11 Pipe opening 10 therefore has a smaller cross section than the other areas of the suction pipe 9. This results in optimized suction of the aroma A and/or the liquid propellant T.

- the suction pipe 9 is U-shaped, with the pipe end being arranged in an upper region of the container interior 8, as in Figure 4 shown.
- the pipe opening 10, which is arranged in the area of the container bottom 4, is therefore not formed at the pipe end here, ie this pipe opening 10 is not identical to the pipe end opening 11, but the pipe opening 10 is in the lower region of the U-shape, in particular at the lowest point the U-shape, designed as in detail in Figure 5 shown.
