Description

The following invention relates to a pressure tapping attachment for beer containers and a corresponding beer tapping method.

Pressure-dispensing taps for the arrangement of beer vessels such as cans or barrels containing several liters of beer, allow the tapping of beer, which is promoted from the container and it is attractively and tastefully filled with appropriate foam crown in glasses. Such dispensers provide in the beer vessel such a pressure of carbonic acid that the beer is conveyed and foamed. The tapping of the beer is then via a tap, which is located near the ground on a vertical wall of the can or barrel.

A print attachment of this kind is in the DE 10 2007 032 414 B4 described by Grittman. There, a printing attachment is disclosed, which can be placed on beverage cans to pressurize the beverage by means of a arranged in the pressure lid carbon dioxide cartridge with gas. The carbon dioxide cartridge is connected via a valve assembly and a sword with the contents of the vessel in contact. To allow the gas to flow from the cartridge into the vessel, it is pushed by means of a lever arrangement against a mandrel, which provides an opening in the carbon dioxide cartridge, respectively in a present in the cartridge neck closure device. The mandrel itself is mounted on a carriage having a bore for directing the gas. The gas may flow through a bore actuatable valve assembly through the bore into a channel system which extends into the sword and may thus flow into the beverage. The gas flow through the channel system is made possible by a rocker arm, which is in operative connection with a piston, so that with appropriate position of the rocker arm, the gas through the bore first into a first channel, from there into a space surrounded by a piston and further in can flow a second channel. The actuation of the piston by the rocker arm causes the gas is forced from the piston chamber into the channel, which opens into the sword. The beverage is then discharged via a tap, which is present on the vertical wall of the container.

Based on this prior art, the present invention based on the object to provide an improved device for supplying pressure in beer vessels available, which allows not only the pressurization of the print attachment and a discharge of the beverage on the essay.

This object is achieved by a pressure tap attachment with the features of independent claim 1.

Further developments of the device are described by the subclaims.

An embodiment of a pressure tapping attachment according to the invention, which can be placed on beer containers, comprises a sword, which extends from the pressure tap attachment in the beer container, and further a CO ₂ cartridge, which is in fluid communication with the sword via a valve assembly , For this purpose, the CO ₂ cartridge in a hood, which forms the quasi the housing of the pressure tap attachment, inclined and arranged with a neck facing up.

The CO ₂ cartridge is slidably mounted in the hood by an actuator against a mandrel, so that the mandrel can penetrate a closure of the cartridge neck and create a channel for the escape of the gas from the cartridge. Further, a bridge member bridges the path from the outlet of the CO ₂ cartridge to a gas-inlet opening in the sword and provides this advantage a duct system and valve means to ₂ cartridge CO ₂ gas in the present of the CO over a Degen CO ₂ channel in the beer container, respectively in the beer, to convict.

In order to cause the cartridge to be pierced, it is necessary to advance it against a piercing means, such as a spike. Actuating means as in this case a rotating mechanism afford this operation. The rotating mechanism is arranged in a recess on a hood edge and can be handled so easily from the outside. It comprises a rotary lever arranged on a vertical axis of rotation. The axis of rotation provides a feed element for advancing the cartridge against a mandrel. The axis of rotation can be designed as an element that performs an eccentric movement. Thus, the axis of rotation may have an oval cross-section and cause the piercing when performing a 180 ° movement. The cartridge can, if it was pierced by advancing, be allowed to slide back and release the opened piercing channel.

Furthermore, the pressure tap attachment according to the invention has a telescopic outlet tube which, if not tapped, can be pushed into the hood. His pointing into the hood end opens into a valve that can be fluidly connected with a riser channel that extends into the sword. The connection is realized by a lever arrangement for opening - and closing again - the valve.

This lever arrangement comprises a lever pivotally arranged on an upper side of the hood, at the end pointing to the valve there is a nose which presses on a spring element when the lever is actuated, which is formed above the valve at the top of the hood. This is how the valve opens and closes.

The spring element may be a leaf spring, which is provided by a U-shaped slot which is introduced into the hood top.

The telescopic outlet pipe further has a handle, which is received in the non-use position in a recess of the hood edge and terminates flush with this.

Since the rotary lever can be rotated 180 ° counterclockwise and can have a shape that is flush with the hood edge in a non-use position, when the rotary lever and the handle are adjacent to each other, a locking engagement for the rotary lever can be created by in a non-use arrangement, an edge of the handle engages an edge of the rotary lever. Thus, it is advantageously achieved that a piercing of the cartridge can take place only after pulling out of the telescopic outlet pipe.

Next can be provided on the sword lug on which the sword with the therein riser channel for beer and with the CO ₂ channel, which opens into the valve or in the bridge element, sealing means for receiving and also fixing the sword attachment to the valve piece.

The bridge element, which bridges the path from the outlet opening of the CO ₂ cartridge to a gas inlet opening in the sword, may have an embodiment as shown in the DE 10 2007 032 414 B4 by Grittman, or by a bridge element which is constructed as follows: It comprises a mandrel which is mounted in a holder and which, parallel to, advantageously directly to the point, comprises a bore extending axially through the holder. The mandrel is slidably disposed against the CO ₂ cartridge. The bore opens into a gap, to which, extending axially further, a sealing element abuts, which is arranged on a stamp. The stamp is stored in a bearing and slidable against a rocker arm.

A bridge part comprises a "piston" or a piston-like or piston-like device, preferably a membrane-covered space. A connection between the space covered by the membrane and the gap into which the gas emerges after the piercing of the cartridge, or its closure means, by pushing against the piercing mandrel, is interrupted by a channel present in the bridge part, which is in a right Angle to the longitudinal axis (AA) of the carbon dioxide cartridge is formed.

From the CO ₂ cartridge gas now flows once to a pressure relief valve, which is located at a lying behind the membrane space, the opposite end of the present in the bridge part channel and is there. A channel branch goes into the cavity under the membrane. Another channel goes into the barrel. By increasing pressure from the CO ₂ cartridge, the membrane is pushed upwards. The membrane in turn pushes the rocker arm upwards, so that it pushes the punch down over a deflection at the hood edge. This stamp is provided at the bottom with the seal, which closes the outlet channel of the cartridge at a fixed barrel pressure.

Thus, a fluidic connection of a second channel, which opens from the piston into the sword, via a membrane space or piston space through the first channel to the CO ₂ cartridge is provided by the advanced punch and thereby tilted rocker arm.

The spatial depth of the pressure tap attachment according to the invention is essentially determined by the size of the carbon dioxide cartridge, which can be arranged in the pressure tap attachment.

The rocker arm is particularly advantageously arranged in such a space-saving manner that the transfer of the gas from a first level, on which the cartridge neck is located, from which the gas exits into the bore, is made possible to a second level, from which the gas into the Beer is transferred. The skilful arrangement of the rocker arm between the two levels allows advantageous with little design effort space saving a carbon dioxide cartridge can be placed on a vessel so that it can be acted upon at the desired time with gas. In this case, the beer, if it is not completely used up, be stored with vascular and pressure tap attachment.

For this purpose, the telescopic outlet pipe, which provides the beer outlet, as well as the actuating lever for the valve and the Ansteck rotary lever are pushed into the hood or accommodated in corresponding recesses, so that the beer container, preferably a tin can with a capacity of up to to 10 l, more preferably with a capacity of 5 l, looks beautiful and can be stored optimally. There are no protruding components on the drum ready to be tapped which could break off or occupy the space.

Finally, embodiments relate to the provision of safety provisions by pressure and check valves.

These and other advantages are set forth by the following description with reference to the accompanying figures.

The reference to the figures in the description is to support the description. Articles or parts of objects which are substantially the same or similar may be given the same reference numerals. The figures are merely schematic representations of embodiments of the invention. It shows:

Basically, the device of the invention refers to a pressure tap attachment that can be placed on a beer container. The pressure tapping attachment is particularly suitable for use with a small container vessel such as a 5 liter beer can, a 10 liter beer can or a beer can of slightly smaller or larger volumes. Such doses are cheaply manufacturable. The advantageous design of the pressure tap attachment according to the invention allows easy placement on a top of the standing beer can by one edge of the hood, which receives the components of the pressure tap attachment under it, is brought into engagement with an edge of the beer can. The sword is performed when placing the pressure tap attachment on the beer can through appropriately provided openings on the barrel top, and the hood is firmly locked at the edge.

Due to the low height of the pressure tap attachment, the dimensions of the beer keg are changed only slightly, resulting in a little increased space requirements, although the pressure tap attachment provides elements that allow on the one hand a supply of beer with fresh CO ₂ and at the same time Allow taps of the beer.

In the present case, the term "use arrangement" is used when one of the components is brought into a position in which the beer can is ready to pour, a non-use arrangement, however, means a positioning of the components on the keg so that it can be stored, where it is not ready to pour ,

1 to 10 shows the pressure tap attachment according to the invention, the sword 2 , seen from about 2 , having. The sword 2 is the about a valve assembly with a carbon dioxide cartridge 3 in connection.

In principle, a sword is understood here to mean a tube which is arranged essentially perpendicular to the device plane in which the gas cylinder is located. The sword can be fixed to the pressure tap attachment or be plugged at the junction of the sword, so the sword attachment, connection and sealing means must be provided so that a secure coupling with the opening to the telescope outlet valve and with the CO ₂ providing bridge element is guaranteed. Furthermore, the sword is suitable to be introduced by a corresponding opening provided in a barrel in the barrel. The sword can protrude accordingly deep into the barrel; In addition to the CO2 channel, it includes the riser pipe for the beer to be conveyed.

As 1 shows, an inventive pressure dispensing attachment 101 which can be placed on a beer container, a clip-on sword 102 comprising, via a valve assembly which in 1 not fully shown, with a CO ₂ cartridge 103 , please refer 3 , is fluidically coupled.

"Fluidic coupling" means in the present case that the CO ₂ gas can flow via the valve means into the beer contained in the beer container by being guided over the channels and valves described below, essentially united in a "bridge element".

This is the CO ₂ cartridge 103 in the hood 101 ' , please refer 3 , against a footstep 122 supported by holding means - here a support sprayed in the lid - held on the neck so supported that the neck of the CO ₂ cartridge 103 is arranged facing up. Preferably, the inclination of the CO ₂ cartridge 103 at least 5 to 15 °, in order to avoid icing of the effluent CO ₂ gas beer beer. The CO ₂ cartridge 103 can be pushed by an actuator against a mandrel, which provides an opening channel on the cartridge neck.

To advance the CO ₂ cartridge 103 To realize against the opening means is present as an actuating device, a rotating mechanism 310 , please refer 5 to 9 , proposed. The turning mechanism 310 is in a recess 312 at the hood edge 101 '' arranged. It includes on a vertical axis of rotation 313 that also in 3 you can see feed means to the CO ₂ cartridge 103 to advance against a thorn.

This feed means can already be represented by the fact that the axis of rotation has an oval cross section, so that when rotated through 180 ° an eccentric movement of the axis of rotation, at a bottom of the CO ₂ cartridge 103 is applied, executed and causes a feeding of the cartridge.

Furthermore, it is possible as in 5 shown as a feed means a spring bolt element 314 to provide that at the axis of rotation 313 is rotatably fixed. 5 shows the spring bolt element 314 in the use position. There it extends to provide the feed of the CO ₂ cartridge 103 through to the bottom of the CO ₂ cartridge 103 pointing opening of the axis of rotation 313 surrounding wall 315 , Before the spring bolt element 314 is used, it is held in a biased position in a gap through the aforementioned wall 315 is limited.

Furthermore, the pressure tapping attachment according to the invention 101 advantageous a telescopic outlet pipe 301 on, also in the hood 101 ' is mounted.

In a non-use state is the telescopic outlet pipe 301 completely in the hood 101 ' receivable, its outlet for beer 302 in a convenient handle 301 ' opens, becomes then in a recess 316 at the hood edge 101 '' taken up flush, like 2 shows. This is advantageously prevented that the outlet can be canceled.

Will the telescopic outlet pipe 301 from a use position, as in 1 is shown transferred to a non-use position as shown in FIG 2 is shown, then only the outer tube part is pushed over the inner tube part. That in the hood 101 ' pointing in the end of the telescopic outlet pipe 301 flows into a valve 320 that with a riser 300 for beer, in the sword 102 extends, so that is connected to the beer over the riser 300 the valve 320 passing through the telescopic outlet pipe 301 from the beer outlet 302 can be flowed.

To cause the beer to escape, a lever arrangement must be used 104 be pressed: This is in 1 shown in their use position. The lever arrangement 104 is at a top of the hood 101 ' by means of a swivel joint 323 hinged so that the lever 104 can be pulled up and arranged at a lower end pressure nose 324 against one above the valve 320 arranged leaf spring 325 suppressed. This leaf spring element 325 is realized here in the simplest way, by a U-shaped slot 325 ' as shown in 7 and 9 , in the top of the hood 101 ' is cut.

As it turned out 6 to 9 clearly shows, according to the invention, the rotating mechanism 310 by means of a rotary lever 311 can be set in motion, which has a shape that in both a non-use position as well as in a position of use with the hood edge 101 '' can finish flush. This is particularly advantageous in the non-use position, as on the one hand no supernatants from the pressure tap attachment 101 protrude, and on the other hand, especially if the rotary lever 311 is designed so that its operation takes place by means of a 180 ° rotation in the counterclockwise direction, can be locked against unwanted operation.

This is done by turning the lever 311 of the rotating mechanism 310 and the handle 301 ' of the telescopic outlet pipe 301 are arranged side by side so that one edge of the handle 301 ' with an edge of the rotary lever 311 comes into locking engagement, like 8th and 9 demonstrate. An impulse against the rotary lever causes this against the inside of the edge of the handle 301 ' However, the 180 ° rotation is not performed without great effort when the telescopic outlet pipe 301 is in non-use position.

If the telescopic spout 301 is pulled out, is the rotary lever 311 freely rotatable and a rotational movement of 180 °, a piercing of the gas cartridge 103 cause by the corresponding opening means, as a feed of the cartridge 103 is done.

This feed can either be provided by the rotation axis 313 , as in 3 shown to have an oval diameter, allowing the rotation of the axis 313 to perform an eccentric movement and thus advancing the at the axis of rotation 313 adjacent CO ₂ cartridge 103 causes in the footrest 122 is supported. Due to the inner shape of the hood, as in 3 is shown is also a good leadership of the CO ₂ cartridge 103 guaranteed.

As an alternative to the simple design of the oval cross-section of the axis of rotation, it is also possible, as in 5 shown a spring bolt element 314 at the axis of rotation 313 to arrange. This spring bolt element 314 is with the rotation axis 313 rotatable and is biased in a non-use position in a gap, passing through the wall 315 is limited. Turning the rotary lever 311 180 ° in the direction of the arrow a, like 8th and 10 show, there is the spring pin of the spring bolt member 314 free, and he pushes against the bottom of the CO ₂ cartridge 103 and gives this feed.

The bridge element that provides the required channels and valve means for transferring the CO ₂ gas from the cartridge into the corresponding CO ₂ channel 103 ' The sword provides essentially through 11 shown a bridge element according to DE 10 2007 032 414 B4 represents.

Out 11 it becomes clear that the carbon dioxide cartridge 3 by a lever arrangement 4 , which is accessible and operable from the outside of the pressure tap attachment, against one on the inside of the print attachment 1 - There is only one print attachment revealed - arranged mandrel 5 is so displaceable that the thorn 5 the bullet 3 opens. The thorn 5 is on a bracket 6 arranged and has an axial longitudinal bore 5 ' on. The hole 5 ' opens into a gap at the axially extending further, a sealing element 9 adjacent to a stamp 8th is arranged. The sealing element 9 may be made of rubber or other suitable material such as Teflon or plastic. Further, its shape may take other than the disc shape, other suitable geometric shapes such as a ring shape or cylindrical shape

The Stamp 8th is mounted in a bearing and slidable against a rocker arm 11 , A bridge part in the bridge element 113 - The section that represents the bridge element is approximately broken in 5 highlighted - in the inventive devices comprises, as in 11 shown one with a membrane 16 with a covered room 17 , A connection between that with the membrane 16 covered room 19 and the gap into which the gas emerges after piercing the cartridge, or its closure means, by pre-printing against the piercing spike, is passed through a channel present in the bridge part 14 which is at right angles to the longitudinal axis (AA) of the carbon dioxide cartridge 3 runs, formed.

From the CO ₂ cartridge 3 Gas now flows once to a pressure relief valve 27 at one behind the membrane space 17 lying, opposite end of the present in the bridge part channel 14 is arranged and stands there. A channel branch goes into the cavity 17 under the membrane. Another channel 18 goes into the barrel. By increasing pressure from the CO ₂ cartridge 3 becomes the membrane 16 pushed up. The membrane 16 in turn pushes the rocker arm 11 to the top: The rocker arm 11 lies so on the inside of the edge 1'' the hood, which unites the individual components of the pressure attachment under it, that the lever 11 can tilt; he points to this a rounding off 19 on that, as in 11 is shown on a contact surface 19 ' of the hood edge 1'' is supported. The hood edge 1'' is therefore on its outside by longitudinal ribs 28 stiffened. When the rounding off 19 of the lever 11 is arranged eccentrically, as shown herein, a smaller punch movement is effected. By tilting the rocker lever 11 becomes the stamp 8th pushes down. This stamp 8th is at the bottom with the gasket 9 provided with a fixed barrel pressure the outlet channel of the cartridge 3 closes.

The rocker arm 11 is advantageously arranged so that the gas flowing from the pierced cartridge neck is transferred from its higher level under pressure reduction to the lower level at which the sword is located. That in the room 17 contained CO ₂ flows over the sword 2 in the vessel not shown figuratively.

As in 11 becomes clear, the stamp of the invention 8th have a bulge, with a corresponding in the rocker lever 11 present recess corresponds.

So the bridge element that is in 11 is shown, suitable as a bridge element 113 as shown in 5 to be used. It should be noted that upon receipt of the functionality of 11 minor changes are possible.

Such as 10 shows, the rocker arm 111 also against a solid surface provided a contact surface 119 be supported by the rounding off 119 of the rocker arm 111 is there. Components of the bridge element 113 , incidentally, by the dashed encirclement in 5 will be clarified, also in 4 shown: The neck of the gas cartridge 103 which is in a vertical support means of the hood 101 ' is held, flows into a holder 106 ; the stamp is with 108 designated. He occurs after provision of the gas pressure in the manner described with the rocker arm 111 engaged.

The valve means used to shut off the telescopic spout 301 are used, are known in the art. This in 1 shown valve 320 has a shut-off pin which can be moved in a piston and which is activated by the pressure of the pressure nose 324 of the lever 104 on the spring element 325 is guided over the elastic cap on the valve in the piston down and thus a passage from the riser 300 over the valve into the spout free, leaving the beer over the outlet 302 can be flowed.

Thus, the pressure tap attachment according to the invention provides a shapely, cleverly manageable, little space-consuming essay available, which makes it possible to apply the beer at the same time with CO ₂ to present it freshly foaming over the telescope outlet device. An arrangement of a separate tap has been advantageously obsolete by the present invention. This eliminates the risk of canceling such a cock or the leakage of retractable taps, whereby an improved storage and handling of the device is ensured.
