Description

Die Erfindung betrifft ein Druckgasflaschenbündel mit Originalitätssicherung, mit mehreren in einem Bündelgestell aufgenommenen Druckgasflaschen, die an eine gemeinsame, mit wenigstens einem Entnahmeventil ausgerüstete Verrohrung angeschlossen sind, wobei das Entnahmeventil im Bereich einer von Gestellelementen des Bündelgestells begrenzten Zugangsöffnung angeordnet ist.The invention relates to a compressed gas cylinder bundle with tamper-evident security, with several compressed gas cylinders accommodated in a bundle frame, which are connected to a common piping equipped with at least one extraction valve, the extraction valve being arranged in the area of an access opening delimited by frame elements of the bundle frame.

Zum Lagern von Druckgasen und Flüssigkeiten werden Druckgasflaschen eingesetzt, die in der Regel aus Stahl, Aluminium oder einem Verbundmaterial gefertigt sind. Derartige Druckgasflaschen werden aufgrund gesetzlicher Vorgaben durch einen gasartspezifischen Anstrich sowie einen Aufkleber, der Informationen über beispielsweise Inhalt, Fülldruck und Hersteller gibt, gekennzeichnet. Daneben bringen einige Lieferanten zusätzlich Originalitätssicherungen an, wie sie beispielsweise in der DE 100 62 867 A1 und der DE 196 11 970 A1 beschrieben werden. Das Vorhandensein bzw. die Unversehrtheit der Originalitätssicherung dient dem Zweck, deren Originalzustand nach der Befüllung im Lieferantenwerk anzuzeigen.Pressurized gas cylinders, which are usually made of steel, aluminum or a composite material, are used to store compressed gases and liquids. Such pressurized gas cylinders are characterized by a gas type-specific coating and a sticker that provides information on, for example, content, filling pressure and manufacturer, based on legal requirements. In addition, some suppliers also apply tamper evidence, such as those in the DE 100 62 867 A1 and the DE 196 11 970 A1 to be discribed. The presence or the intactness of the tamper-evident system serves the purpose of indicating its original condition after filling in the supplier's plant.

In der FR 2 642 142 A1 wird eine Anordnung zum Speichern vom Flüssiggas, beispielsweise Butan beschrieben. Die Anordnung umfasst mehrere Druckgasbehälter, die jeweils mit einem Entnahmeventil ausgerüstet sind. Um die Anordnung in Betrieb zu setzen werden die Entnahmeventile mittels einer Anschlussmechanik gleichzeitig mit einer Verrohrung verbunden. Nach Entleerung der Druckgasbehälter ist bei diesem Gegenstand jedoch keine Wiederbefüllung vorgesehen.In the FR 2 642 142 A1 describes an arrangement for storing liquefied petroleum gas, for example butane. The arrangement comprises several pressurized gas containers, each equipped with an extraction valve. In order to put the arrangement into operation, the extraction valves are simultaneously connected to piping by means of a connection mechanism. After the pressurized gas container has been emptied, no refilling is provided for this item.

Um einen größeren Gasebedarf eines Kunden abzudecken, kommen in zunehmendem Maße Flaschenbündel zum Einsatz. Dabei handelt es sich um Anordnungen, bei denen mehrere, beispielsweise 4, 6, 8, 12, 18 oder 28 Druckgasflaschen stehend oder liegend innerhalb eines Bündelgestells zusammengefasst und mittels einer Verrohrung strömungstechnisch miteinander verbunden sind. Zur Gasentnahme ist das Flaschenbündel mit einem oder mehreren Entnahmeventilen ausgerüstet; beispielsweise ist ein erstes Entnahmeventil zur Entnahme bei einem den Flaschenfülldruck entsprechenden Druck von 300 bar vorgesehen, und ein zweites mit einem integrierten Druckreduzierer ausgerüstetes Entnahmeventil ermöglicht die Entnahme bei einem Druck von 200 bar.In order to cover a larger gas requirement of a customer, cylinder bundles are increasingly being used. These are arrangements in which several, for example 4, 6, 8, 12, 18 or 28 pressurized gas cylinders standing or lying together within a bundle frame and fluidically connected to one another by means of piping are connected. The cylinder bundle is equipped with one or more extraction valves for gas extraction; For example, a first extraction valve is provided for extraction at a pressure of 300 bar corresponding to the bottle filling pressure, and a second extraction valve equipped with an integrated pressure reducer enables extraction at a pressure of 200 bar.

Bei stehenden Flaschenbündeln ist das Bündelgestell aus Sicherheitsgründen derart ausgebildet, dass sämtliche Druckgasflaschen des Bündels, die Verrohrung und das bzw. die Entnahmeventil/e vollständig innerhalb der Rahmenelemente des Bündelgestells aufgenommen sind. Insbesondere ist auch das Entnahmeventil bzw. sind die Entnahmeventile im Bündelgestell zurückgesetzt gegenüber der von den äußeren Rahmenelementen des Bündelgestells gebildeten Außenfläche des Flaschenbündels angeordnet. Um den Zugriff auf das Entnahmeventil zu gewährleisten, weist das Bündelgestell im Bereich des Entnahmeventils eine Zugangsöffnung auf, die entweder als Aussparung innerhalb eines einzelnen Rahmenelements gebildet wird, oder aber von mehreren Rahmenelementen begrenzt wird, die seitlich, oberhalb und unterhalb des Entnahmeventils gruppiert sind.In the case of upright cylinder bundles, the bundle frame is designed for safety reasons in such a way that all of the compressed gas cylinders in the bundle, the piping and the extraction valve (s) are completely within the frame elements of the Bundle frame are added. In particular, the removal valve or the removal valves in the bundle rack is also arranged set back with respect to the outer surface of the bottle bundle formed by the outer frame elements of the bundle rack. To ensure access to the extraction valve, the bundle frame has an access opening in the area of the extraction valve, which is either formed as a recess within a single frame element, or is delimited by several frame elements that are grouped laterally, above and below the extraction valve.

Derartige Flaschenbündel werden heute zur Kennzeichnung der Originalität in der Regel lediglich mit Klebebändern versehen, die sich quer über das Entnahmeventil erstrecken. Allerdings lassen derartige Klebebänder in Bezug auf die Zuverlässigkeit der Originalitätssicherung zu wünschen übrig. Aufgrund der fest installierten und mit allen Druckgasflaschen des Bündels verbundenen Verrohrung ist es im Übrigen nicht möglich, von Einzelflaschen her bekannte Originalitätssicherungen bei Flaschenbündeln einzusetzen.Such bundles of bottles are nowadays usually only provided with adhesive tapes, which extend across the removal valve, in order to identify their originality. However, such adhesive tapes leave something to be desired with regard to the reliability of the tamper-evident security. Due to the permanently installed piping connected to all the compressed gas cylinders in the bundle, it is also not possible to use tamper-evident security devices for bundles of cylinders known from individual cylinders.

Der Erfindung liegt daher die Aufgabe zugrunde, eine zuverlässige Originalitätssicherung für Druckgasflaschenbündel zu schaffen.The invention is therefore based on the object of creating a reliable tamper-evident feature for bundles of compressed gas cylinders.

Diese Aufgabe wird bei einer Originalitätssicherung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of claim 1 with an authenticity assurance.

Das erfindungsgemäß ausgerüstete Druckgasflaschenbündel umfasst also eine durch Rahmenelemente des Flaschenbündels begrenzte oder als eine Aussparung innerhalb eines Rahmenelements gebildete Zugangsöffnung für das Entnahmeventil oder, entsprechend der Anzahl der Entnahmeventile, mehrere Zugangsöffnungen. An der Zugangsöffnung einander gegenüberliegende Rahmenelemente (bzw. gegenüberliegende Seiten der eine Zugangsöffnung bildenden Aussparung innerhalb eines Rahmenelements) weisen jeweils zwei oder mehr Bohrungen zum Verbinden des Sicherungselements auf.The pressurized gas cylinder bundle equipped according to the invention thus comprises an access opening for the extraction valve that is delimited by frame elements of the cylinder bundle or formed as a recess within a frame element or, depending on the number of extraction valves, several access openings. At the access opening opposite frame elements (or opposite sides of the recess forming an access opening within a frame element) each have two or more bores for connecting the securing element.

Das Sicherungselement umfasst beispielsweise einen Sicherungsabschnitt in Form eines langgestreckten Fadens oder bandförmigen Körpers aus Kunststoff, an dessen kopfseitigen Enden die Verbindungselemente angeordnet sind. Im Einbauzustand des Sicherungselements werden die Verbindungselemente derart durch die Bohrungen hindurchgeführt, dass sich der langgestreckte Sicherungsabschnitt des Sicherungselements quer über das Entnahmeventil oder den Entnahmeanschluss erstreckt und somit eine Gasentnahme verhindert. Die Verbindungselemente sind dazu jeweils mit einem Halteabschnitt ausgerüstet, der im Einbauzustand auf der dem Sicherungsabschnitt entgegen gesetzten Seite der Bohrung angeordnet ist und die Entfernung des Sicherungselements erschwert oder verhindert.The securing element comprises, for example, a securing section in the form of an elongated thread or band-shaped body made of plastic, at the ends of which the connecting elements are arranged. In the installed state of the securing element, the connecting elements are passed through the bores in such a way that the elongated securing section of the securing element extends transversely over the extraction valve or the extraction connection and thus prevents gas extraction. For this purpose, the connecting elements are each equipped with a holding section which, in the installed state, is arranged on the side of the bore opposite the securing section and which makes removal of the securing element difficult or impossible.

Beispielsweise wird beim Montieren des Sicherungselements der Halteabschnitt durch die entsprechende Bohrung hindurchgeführt und anschließend beispielsweise fest mit dem Rahmenelement verbunden, oder der Halteabschnitt ist nach Art eines Widerhakens ausgeführt, sodass er nicht oder nur unter großem Aufwand durch die Bohrung zurückgeschoben werden kann. Alternativ handelt es sich beim Halteabschnitt um einen Körper mit größerem Durchmesser als die jeweilige Bohrung im Rahmenelement, der erst nach dem Hindurchführen des (schmaleren) Verbindungselements durch die Bohrung unlösbar mit diesem verbunden wird. Somit kann die Originalitätssicherung nicht ohne weiteres entfernt werden, ohne sie zu zerstören.For example, when assembling the securing element, the holding section is passed through the corresponding bore and then, for example, firmly connected to the frame element, or the holding section is designed in the manner of a barb so that it cannot be pushed back through the bore or only with great effort. Alternatively, the holding section is a body with a larger diameter than the respective hole in the frame element, which is only permanently connected to the hole after the (narrower) connecting element has been passed through the hole. Thus, the tamper evident cannot be easily removed without destroying it.

Mit der Erfindung wird eine einfach zu handhabende und zuverlässige Originalitätssicherung für Druckgasflaschenbündel gewährleistet. Da die erfindungsgemäße Originalitätssicherung zur Befestigung des Sicherungselements lediglich das Vorsehen entsprechender Bohrungen in den Rahmenelementen des Bündelgestells erfordert, ist es zudem problemlos möglich, auch bereits vorhandene Druckgasflaschenbündel mit einer erfindungsgemäßen Originalitätssicherung nachzurüsten.The invention ensures an easy-to-use and reliable tamper-evident security for compressed gas cylinder bundles. Since the inventive tamper-evident system for fastening the security element only requires the provision of corresponding bores in the frame elements of the bundle frame, it is also easily possible to retrofit existing compressed gas cylinder bundles with an inventive tamper-evident system.

Bevorzugt ist das Sicherungselement mit einer Sollbruchstelle ausgerüstet. Dabei handelt es sich beispielsweise um einen Materialabschnitt mit einer gegenüber den übrigen Abschnitten des Sicherungselements geringeren mechanischen Stabilität, etwa eine Einkerbung oder eine sonstige Querschnittsverengung. Die Sollbruchstelle kann beispielsweise im Sicherungsabschnitt angeordnet sein, oder aber im Bereich eines Verbindungsabschnitts oder der Verbindungsabschnitte. Im letzteren Falle wird beim Entfernen des Sicherungselements vermieden, dass die Verbindungsabschnitte des Sicherungselements im Bereich der Bohrungen zurückbleiben und vor einer späteren Neubefüllung des Druckgasflaschenbündels aufwändig entfernt werden müssten.The securing element is preferably equipped with a predetermined breaking point. This is, for example, a material section with a lower mechanical stability compared to the other sections of the securing element, for example a notch or some other narrowing of the cross-section. The predetermined breaking point can be arranged, for example, in the securing section, or else in the area of a connecting section or the connecting sections. In the latter case, when the securing element is removed, it is avoided that the connecting sections of the securing element remain in the region of the bores and would have to be laboriously removed before the compressed gas cylinder bundle is later refilled.

Eine besonders vorteilhafte Originalitätssicherung ist dadurch gekennzeichnet, dass wenigstens ein Verbindungselement als Halteelement einen kugel-, kegel- oder kegelstumpfförmigen Kopfabschnitt aus einem elastischen Material aifweist, dessen Kugelfläche bzw. Kegelgrundfläche geringfügig größer als die Querschnittsfläche der entsprechenden Bohrung im Gestellelement ist. Bei der Montage dieser Variante der erfindungsgemäßen Originalitätssicherung werden die Verbindungselemente also mit ihrem Kopfabschnitt durch die entsprechenden Bohrungen in den Rahmenelementen des Bündelgestells hindurchgepresst. Im Einbauzustand befindet sich der Kopfabschnitt auf der dem Sicherungsabschnitt gegenüberliegenden Seite der Bohrung. Aufgrund der elastischen Eigenschaft des Materials des Kopfabschnitts weitet sich dieses wieder auf und kann nicht ohne weiteres durch die Bohrung zurückgeschoben werden.A particularly advantageous tamper-evident feature is that at least one connecting element has a spherical, conical or frustoconical head section made of an elastic material, the spherical surface or conical base surface of which is slightly larger than the cross-sectional area of the corresponding hole in the frame element. During the assembly of this variant of the tamper-evident device according to the invention, the connecting elements are therefore pressed with their head section through the corresponding bores in the frame elements of the bundle frame. In the installed state, the head section is located on the side of the bore opposite the securing section. Due to the elastic property of the material of the head section, it expands again and cannot easily be pushed back through the bore.

Eine abermals vorteilhafte Ausgestaltung sieht dabei vor, dass das Verbindungselement einen sich an den Kopfabschnitt anschließenden, die Verbindung zum Sicherungsabschnitt herstellenden Sollbruchabschnitt mit verkleinertem Querschnitt aufweist. Der Kopfabschnitt ist also mit dem übrigen Sicherungselement über den Sollbruchabschnitt verbunden, der sich im Einbauzustand durch die Bohrung hindurcherstreckt. Beim Entfernen des Sicherungselements reißt der Verbindungsabschnitt an der Sollbruchstelle auf, und das gesamte Sicherungselement kann leicht vom Flaschenbündel abgelöst werden.Another advantageous embodiment provides that the connecting element has a predetermined breaking section, which adjoins the head section and establishes the connection to the securing section, with a reduced cross section. The head section is therefore connected to the rest of the securing element via the predetermined breaking section, which extends through the bore in the installed state. When the securing element is removed, the connecting section tears open at the predetermined breaking point, and the entire securing element can easily be detached from the bundle of bottles.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass am Sicherungsabschnitt des Sicherungselements ein Verstärkungsteil mit einer gegenüber dem übrigen Sicherungsabschnitt größerer Breite und/oder Dicke vorgesehen ist. Das Verstärkungsteil befindet sich im Einbauzustand dabei bevorzugt genau über dem Entnahmeventil und dient in diesem Fall dazu, das Entnahmeventil zusätzlich gegen Zugriff zu sichern. Das Verstärkungsteil kann mit seiner vergrößerten Breite insbesondere auch als Informationsträger oder Werbefläche dienen.An advantageous development of the invention provides that a reinforcement part with a greater width and / or thickness compared to the rest of the securing section is provided on the securing section of the securing element. That In the installed state, the reinforcement part is preferably located exactly above the extraction valve and in this case serves to additionally secure the extraction valve against access. With its enlarged width, the reinforcement part can in particular also serve as an information carrier or advertising surface.

Bevorzugt sind der Sicherungsabschnitt und/oder die Verbindungselemente und/oder das Verstärkungsteil einstückig ausgebildet. Als bevorzugter Werkstoff für den Sicherungsabschnitt und/oder die Verbindungselemente und/oder das Verstärkungsteil wird ein Kunststoff angesehen, vorzugsweise Polyamid.The securing section and / or the connecting elements and / or the reinforcing part are preferably designed in one piece. A plastic, preferably polyamide, is regarded as the preferred material for the securing section and / or the connecting elements and / or the reinforcement part.

Das in Fig. 1 gezeigte Druckgasflaschenbündel 1 umfasst eine Anzahl von Druckgasflaschen 2, 2', 2", die in an sich bekannter Weise innerhalb eines Bündelgestells 3 aufgenommen sind. Die Druckgasflaschen 2, 2', 2" sind durch eine Verrohrung 5 strömungstechnisch miteinander verbunden, an der, in ebenfalls an sich bekannter Weise, ein Druckanzeigegerät 6 sowie ein Entnahmeventil 7 mit Handrad 8 und Entnahmeanschluss 9 angeordnet ist. Nicht gezeigt, jedoch im Rahmen der Erfindung möglich, sind ein oder mehrere zusätzliche Entnahmeventile, an denen die Entnahme von Gas zum gleichen Druck wie am Entnahmeventil 9 oder - bei Zwischenschaltung eines Druckminderers am betreffenden Entnahmeventil - zu verminderten Drücken möglich ist.This in Fig. 1 The pressurized gas cylinder bundle 1 shown comprises a number of pressurized gas cylinders 2, 2 ', 2 "which are accommodated in a manner known per se within a bundle frame 3. The pressurized gas cylinders 2, 2', 2" are fluidically connected to one another by piping 5, on which, in a manner also known per se, a pressure indicator 6 and an extraction valve 7 with a handwheel 8 and extraction connection 9 are arranged. Not shown, but possible within the scope of the invention, are one or more additional extraction valves at which the extraction of gas at the same pressure as at extraction valve 9 or - with the interposition of a pressure reducer on the extraction valve in question - at reduced pressures is possible.

Das Bündelgestell 3 umfasst einen äußeren, im Ausführungsbeispiel im Wesentlichen quaderförmigen Rahmen 11 aus beispielsweise durch Verschweißen miteinander verbundenen Metallprofilen, beispielsweise aus Stahl. Der Rahmen 11 ist so bemessen, dass alle Gasflaschen 2, 2', 2", die Verrohrung 5 sowie das Entnahmeventil 7 innerhalb der Außenflächen des Rahmens 11 angeordnet sind. Zusätzliche seitliche Rahmenprofile 12, 13 dienen insbesondere dazu, ein seitliches Herausgleiten der Druckgasflaschen 2, 2', 2" zu verhindern. Um den Transport des Druckgasflaschenbündels 1 zu erleichtern, weist der Rahmen 11 des Weiteren einen palettenartigen Bodenabschnitt 14 sowie angeschweißte Tragösen 15, 15' auf.The bundle frame 3 comprises an outer, in the exemplary embodiment essentially cuboid frame 11 made, for example, by welding interconnected metal profiles, for example made of steel. The frame 11 is dimensioned such that all gas cylinders 2, 2 ', 2 ", the piping 5 and the extraction valve 7 are arranged within the outer surfaces of the frame 11. Additional lateral frame profiles 12, 13 serve in particular to prevent the compressed gas cylinders 2 from sliding out laterally To prevent, 2 ', 2 ". In order to facilitate the transport of the bundle of pressurized gas cylinders 1, the frame 11 furthermore has a pallet-like base section 14 and welded-on eyelets 15, 15 '.

Der obere Teil des Rahmens 11 und das Rahmenprofil 12 begrenzen eine Zugangsöffnung 16, durch die hindurch das Entnahmeventil 7 zugänglich ist und eine hier nicht gezeigte Gasanschlussleitung am Entnahmeanschluss 9 befestigt werden kann. Zum Vorsehen einer Originalitätssicherung ist sowohl in einem oberhalb des Entnahmeventils 7 verlaufenden Rahmenelement 17 als auch dem seitlichen Rahmenprofil 12 oberhalb bzw. unterhalb des Entnahmeventils 7 jeweils eine Bohrung 18, 19 vorgesehen.The upper part of the frame 11 and the frame profile 12 delimit an access opening 16 through which the extraction valve 7 is accessible and a gas connection line (not shown here) can be attached to the extraction connection 9. A bore 18, 19 is provided both in a frame element 17 running above the extraction valve 7 and in the side frame profile 12 above or below the extraction valve 7 to provide a tamper-evident feature.

In der Fig. 2a ist in einem vergrößerten Ausschnitt der Rahmen 11 und eine daran zu befestigende Originalitätssicherung gezeigt. Die Originalitätssicherung umfasst ein Sicherungselement 20 aus einem flexiblen Kunststoffmaterial, das sich im Einbauzustand mit einem Sicherungsabschnitt 21 quer über die Zugangsöffnung 16 im Bereich des Entnahmeanschlusses 9 erstreckt, diesen überdeckt und so verhindert, dass eine Gasentnahme ohne Entfernung oder Zerstörung des Sicherungselements 20 möglich ist. Im Bereich seiner beider Enden sind am Sicherungsabschnitt 21 jeweils Verbindungsabschnitte 22, 22' zum Befestigen in den Bohrungen 18, 19 vorgesehen, die bevorzugt einstückig mit dem Sicherungsabschnitt 21 ausgebildet sind. Die Verbindungsabschnitte 22, 22' weisen jeweils einen kugel-, kegel- oder kegelstumpfförmigen Kopfabschnitt 23, 23' aus einem elastischen Material auf, dessen größter Außendurchmesser gleich oder geringfügig größer als der Innendurchmesser der Bohrungen 18, 19 ist. An den Kopfabschnitt 23, 23' schließt sich jeweils eine Sollbruchstelle 24, 24' an, die aus dem gleichen Material wie der Kopfabschnitt 23, 23' gefertigt ist, jedoch aufgrund eine stark verkleinerten Querschnittfläche eine deutlich geringere mechanische Stabilität als diese aufweist.In the Fig. 2a is shown in an enlarged section of the frame 11 and a tamper evident to be attached. The tamper-evident device comprises a securing element 20 made of a flexible plastic material which, in the installed state, extends with a securing section 21 across the access opening 16 in the area of the extraction connection 9, covers it and thus prevents gas extraction from being possible without removing or destroying the safety element 20. In the area of both of its ends, connecting sections 22, 22 ′ are provided on securing section 21 for fastening in bores 18, 19, which are preferably designed in one piece with securing section 21. The connecting sections 22, 22 'each have a spherical, conical or frustoconical head section 23, 23' made of an elastic material, the largest outer diameter of which is equal to or slightly larger than the inner diameter of the bores 18, 19. The head section 23, 23 'is followed by a predetermined breaking point 24, 24', which is made of the same material as the head section 23, 23 ', but has a significantly lower mechanical stability than this due to a greatly reduced cross-sectional area.

Beim Befestigen des Sicherungselements 20 werden die Verbindungsabschnitte 22, 22' in Pfeilrichtung in die Bohrungen 18, 19 hineingedrückt. Die Sollbruchstellen 24, 24' sind dabei so ausgebildet, dass im Einbauzustand die Kopfabschnitte 23, 23' vollständig auf der vom Sicherungsabschnitt 21 entgegen gesetzten Seite des Rahmenprofils 12 bzw. des Rahmenelements 17 angeordnet sind. Aufgrund ihrer elastischen Konsistenz und ihrer gegenüber der jeweiligen Bohrung 18, 19 vergrößerten Durchmessers können die Kopfabschnitte 23, 23' anschließend nicht mehr aus der entsprechenden Bohrung 18, 19 herausgezogen werden, ohne dass das Sicherungselement 20 an den Sollbruchstellen 24, 24' reißt.When fastening the securing element 20, the connecting sections 22, 22 ′ are pressed into the bores 18, 19 in the direction of the arrow. The predetermined breaking points 24, 24 'are designed in such a way that, in the installed state, the head sections 23, 23' are arranged completely on the side of the frame profile 12 or the frame element 17 opposite from the securing section 21. Due to their elastic consistency and their enlarged diameter compared to the respective bore 18, 19, the head sections 23, 23 'can then no longer be pulled out of the corresponding bore 18, 19 without the securing element 20 tearing at the predetermined breaking points 24, 24'.

In der Ausführungsform nach den Fig. 2a und 2b ist das Sicherungselement 20 im Bereich des Sicherungsabschnitts 21 mit einem verbreiterten Verstärkungsteil 25 ausgerüstet, der im Einbauzustand über dem Entnahmeanschluss 9 angeordnet ist und durch den die Zuverlässigkeit der Originalitätssicherung verbessert wird. Das Verstärkungsteil 25 ist entweder einstückig mit dem Sicherungsabschnitt 21 ausgebildet oder als ein separates Element, das zwei schlitzförmige Öffnungen zum Einschieben des Sicherungsabschnitts 21 aufweist, und das vor dem Einbau des Sicherungselements 20 mit diesem verbunden wird. Die Oberfläche des Verstärkungsteils 25 ist insbesondere auch als Informationsträger einsetzbar und kann beispielsweise mit Informationen über den Inhalt des Druckgasflaschenbündels 1 und/oder den Lieferanten versehen werden.In the embodiment according to Figures 2a and 2b the securing element 20 is equipped in the area of the securing section 21 with a widened reinforcing part 25 which, in the installed state, is arranged above the extraction connection 9 and which improves the reliability of the tamper-evident security. The reinforcement part 25 is either formed in one piece with the securing section 21 or as a separate element which has two slot-shaped openings for inserting the securing section 21 and which is connected to the securing element 20 before it is installed. The surface of the reinforcement part 25 can in particular also be used as an information carrier and can, for example, be provided with information about the contents of the compressed gas cylinder bundle 1 and / or the supplier.

Mit der erfindungsgemäßen Originalitätssicherung wird eine einfach zu handhabende und zuverlässige Absicherung von Druckgasflaschenbündeln gewährleistet.With the tamper-evident protection according to the invention, an easy-to-use and reliable protection of bundles of compressed gas cylinders is ensured.
