Definitions

  • Container in particular large-volume plastic disposable container such as Keg for receiving drinks
  • the invention relates to a container, in particular a large-volume plastic disposable container such as a keg for receiving liquids, for example for receiving drinks, with a connection fitting with seal.
  • a container in particular a large-volume plastic disposable container such as a keg for receiving liquids, for example for receiving drinks, with a connection fitting with seal.
  • keg barrels which are reusable barrels, which were developed for industrial filling and the germ-free storage of beverages.
  • the term “keg” or “keg” comes from the English language and stands for "small keg.” Keg barrels have largely prevailed in the catering industry and are increasingly used in the private sector in conjunction with associated dispensers.
  • kegs or keg barrels have a valve on their top, the so-called keg head.
  • a suitable tap head can be attached, which is a propellant gas, for example
  • Carbon dioxide or nitrogen supplied from an external container, thus generating an overpressure in the interior of the container in question.
  • This overpressure ensures that the liquid stored in the container or container can be removed via a riser pipe and a dispensing system.
  • the dispensing head closes the container tightly so that the liquid stored in it remains germ-free.
  • the contents of the beverage when opening a tap through the riser inside pushed out of the keg. If the tap head removed, the valve closes the keg airtight, so that a further storage of the content is possible. The drying of any residues is prevented. The pressure inside the barrel remains intact.
  • the keg head or the valve realized at this point represent in the core a special design of the connection fitting specified in the preamble and the seal.
  • the seal ensures that the container or the keg with removed tap head the previously established overpressure inside of the container.
  • an overpressure of up to approx. 3 bar for beer and up to 7 bar for CO2-containing soft drinks is used at this point.
  • the pressures mentioned are the operating pressures of the containers.
  • the safety valve is set to this value.
  • the invention is based on the technical problem of developing a container of the embodiment described in the introduction so that its potential for danger is reduced to a minimum.
  • the invention proposes in a generic container, in particular large-volume plastic disposable containers such as keg for receiving drinks, that the connection fitting and / or the seal after a predetermined opening tion process during the subsequent automatic closing process define a non-closable passage opening for pressure reduction in the container interior.
  • connection fitting and / or the seal consequently, in particular the keg head constructively designed so that after a certain opening operation of the subsequent automatic closing operation is practically not completely performed or completed. Because in this subsequent automatic closing process remains a non-closable passage opening. This passage ensures that it comes in the container interior to reduce pressure. As a result, an overpressure in the interior of the container can no longer build up (as in the case of the prior art) and the risk potential described is logically no longer present.
  • the previously defined opening process is the first opening operation after filling the container.
  • the second, third, tenth or another filling operation subsequent opening operation can be used as a practical initial spark that the subsequent closing process, although still done automatically, but not completely performed, but the non-closable passage opening remains.
  • this procedure takes place immediately after the first opening operation after filling the container.
  • the connection fitting and / or the seal are designed so that a complete sealing completion after first opening no longer occurs. In this way, the overpressure contained in the container can escape without risk.
  • connection fitting is equipped with a stop for the seal.
  • the seal experiences a spring loading and the stop is provided with a predetermined breaking point for the spring-loaded seal. If now after the first opening operation after filling the container, the connection fitting is closed automatically by the seal undergoes a loading by the spring, the predetermined breaking point in or on the stop ensures that the stop of the seal opposes little or no resistance. As a result, the stopper is deformed and / or partially removed and the seal in connection with the stop of the connection fitting is no longer able to completely and automatically seal the container. Rather, this embodiment ensures that the required passage opening is defined for pressure reduction in the container interior.
  • the seal can be equipped with a predetermined breaking point.
  • the automatic closing operation following the predetermined opening operation ensures that the seal undergoes deformation in the region of the predetermined breaking point, so that the through opening is defined.
  • both measures can also be combined, that is, the predetermined breaking point in the stop is connected to the predetermined breaking point in the seal.
  • stop and / or the seal are also within the scope of the invention to equip the stop and / or the seal with a permanent or only a temporary deformation. That is, it is conceivable that the stop only undergoes deformation until the overpressure built up in the container interior has been reduced. The same may apply to the seal, which can only be deformed until the overpressure built up in the container interior has been reduced. In addition, of course, a permanent or temporary limited deformation of the stop as the seal are conceivable.
  • the seal after the specified opening operation during the subsequent closing process can also go into a spaced from its sealing seat at the stop holding position.
  • the holding position may be maintained until the overpressure inside the container is reduced.
  • This can be accomplished, for example, by an additional spring acting on the gasket in the opening sense, in addition to the actual closing spring.
  • the opening of the connection fitting or the seal or the definition of the passage opening permanently, namely during the automatic closing operation, which is completed after the specified opening operation.
  • the seal and / or the connection fitting or the stop of the connection fitting undergo only temporary deformation until the overpressure built up in the container interior has been reduced.
  • the temporary deformation of the seal and / or the connection fitting or the stop of the connection fitting can simply be reversed automatically after a predetermined period of time. In most cases, this period of time will be so generous that within the time span the pressure drop inside the container has definitely taken place. According to experience, time spans of a few seconds, perhaps 10 seconds, are sufficient.
  • Fig. 2 shows a detail of Fig. 1 and
  • FIG. 3a, 3b the container of FIGS. 1 and 2 in the region of the container neck in the automatic closing operation to form the non-closable passage opening.
  • a container which in the exemplary embodiment is a keg 1 made of plastic, in particular PET (polyethylene terephthalate).
  • kegs 1 are used as disposable containers for holding liquids, for example for holding drinks such as beer. After emptying the keg 1, this is generally reduced in volume or compressed and then fed to a recycling.
  • the keg 1 or generally the large-volume disposable plastic container is equipped with a connection fitting 2 with seal 3.
  • the connection fitting 2 including seal 3 is also referred to as a valve or keg head 2, 3.
  • For the basic structure still includes a riser 4 shown in the figures, through which the located in the interior of the container 1 and there bottled liquid is pressed out under pressure.
  • the connection fitting 2 is composed in detail of a fitting body 2a and a stop 2b.
  • the fitting body 2 a is formed as an annular and in cross-section L-shaped flange, which is inserted into a neck 5 of the keg 1.
  • the fitting body or flange 2a may be positively and / or positively connected to the neck 5 of the keg 1, as described in WO 2008/083782 A2.
  • the fitting body or flange 2a serves as a support and stop element for a spring or closing spring 6, which is supported at its foot on the fitting body 2a and with her head the Seal 3 applied, which abuts against the stop 2b on the underside.
  • the riser 4 is arranged stationarily in the keg 1.
  • the tap head described in the introduction is connected to the connection fitting 2. From the tap head can be seen in Fig. 2, only a Tarnamarmatur 7, 8, which is composed in the example shown from a Auf thoroughlyzylinder 7 and a sealing cylinder 8.
  • the sealing cylinder 8 rests against the stop 2b of the connection fitting 2 on the upper side, whereas the push-on cylinder 7 is able to open the seal 3 against the force of the closing spring 6.
  • This is shown in the right part of Fig. 2.
  • two separate paths A and B are defined in the interior of the keg 1 and from the inside out.
  • a non-closable passage opening 9 is defined according to the invention in the subsequent automatic closing operation as shown in FIGS. 3a and 3b.
  • This passage opening 9 serves for pressure reduction in the container interior.
  • the automatic closing process is initiated in the example shown by the tap head being removed. As a result, the push-on cylinder 7 which acts on the seal 3 falls away and places the seal 3 against the stop 2b or the two stops 2b, 2c.
  • connection fitting 2 and the stop 2b is equipped with a predetermined breaking point 10.
  • the breaking point 10 ensures that the seal in the Inside the keg 1 prevailing overpressure in conjunction with the force of the closing spring 6, the stopper 2b, for example, as deformed, as shown in FIG. 3b.
  • the overall design is made such that the topping cylinder 7 has an outside diameter d which is smaller than a diameter d a of the predetermined breaking points 10.
  • the predetermined breaking points 10 follow the circular stop 2b and are altogether on a circle with the diameter d a arranged.
  • the inner diameter dj of the sealing cylinder 8 is now larger than the diameter d a of the predetermined breaking points 10 and essentially corresponds to the outer diameter of the neck 5 of the keg 1.
  • the predetermined breaking points 10 are each arranged so that the stop 2b performs its function, when the seal 3 is closed by means of the closing spring 6, as shown in the left part of Fig. 2. This is true at least as long as the stop 2b is acted upon only by the force of the closing spring 6. Is it against it to one additional structure of the overpressure inside the container or keg 1, the stop 2b can no longer fulfill its function completely or gives the stop 2b in the region of the predetermined breaking points 10 after. This can be attributed to the combined force of the closing spring 6 in conjunction with the pressure prevailing in the interior of the keg 1 overpressure.
  • This overpressure is built up in the keg 1 only when the first opening operation and the squeezing out of the liquid through the riser pipe 4 takes place after the container or keg 1 has been filled. Since in this process the seal 3 is lifted off the stop 2b with the aid of the jacking cylinder 7, the stop 2b is not loaded.
  • FIG. 3a shows a further variant of how the passage opening 9 can be defined for pressure reduction in the container interior in the automatic closing operation following the previously defined opening process or the first opening operation during dispensing of the liquid.
  • the design is made such that the seal 3, after the defined or first opening operation during the subsequent closing operation, merges into a holding position spaced from its sealing seat or the stop 2b, 2c.
  • This holding position according to FIG. 3a may also be referred to as a detent position.
  • the Aufcetzylinder 7 during the first opening process of the keg 1 or when dispensing the beverage, the stop 2b, 2c deformed so that it forms a nose 11, which the seal 3 spaced from the stop during the subsequent automatic closing operation 2b and the stop 2c on the riser 4 holds.
  • the passage opening 9 is again defined, which allows the pressure reduction in the container interior.
  • the outer diameter d of the Aufcetzylinders 7 must be such that the stopper cylinder 7, the stop 2b is detected at the edge and it comes to the described bending or the formation of the nose 11 on the stop 2b.
  • the energy stored in the form of the overpressure in the interior of the keg 1 is reduced and therefore no longer constitutes a potential hazard.
  • the keg 1 may no longer be able to be permanently sealed via the passage opening 9, so that the contents of the keg 1 is irretrievably abandoned to spoilage.
  • Alternative approaches provide that the Passage opening 9 is defined only temporarily and generally after the pressure reduction in the interior of the keg 1 this again undergoes a complete closure. Either way, the security has increased enormously, which was to achieve.
