Abstract

In some fields of application, the need exists to equip gas bottles with an origin-proof closure so that interference with the contents of the bottle can be detected. This purpose is served by a strap which surrounds the valve body at the level of the gas-bottle valve connector nozzle (3). The strap possesses a cap-shaped projection (8) which encompasses the gas-bottle valve connector nozzle (3) and a closure for undetachably connecting the closure ends to each other. The origin-proof closure is preferably designed as an integral plastic moulding. <IMAGE>

Description

Die Erfindung betrifft einen Originalitätsverschluß für Gasflaschenventile.The invention relates to a tamper-evident closure for gas cylinder valves.

Bei der Belieferung mit Industriegasen in Gasflaschen werden den Kunden mit Gas gefüllte Flaschen zur Ver­fügung gestellt, die mit dem Gasflaschenventil und der Ventilschutzkappe versehen komplett angeliefert werden. In manchen Kundenkreisen, insbesondere Militär-, Kraftwerks- und Krankenhausbereich, besteht der Wunsch nach einer erhöhten Absicherung dieser Flaschen gegen unbefugte Manipulationen. Auf den Inhalt der Gasflasche kann nämlich verhältnismäßig leicht durch das Gas­flaschenventil - Anschlußgewinde eingewirkt werden.When supplying industrial gases in gas bottles, customers are provided with gas-filled bottles that are supplied complete with the gas bottle valve and the valve protection cap. In some customer groups, in particular in the military, power plant and hospital sectors, there is a desire for increased protection of these bottles against unauthorized manipulation. The content of the gas bottle can be influenced relatively easily through the gas bottle valve connection thread.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Originalitätsverschluß für Gasflaschenventile zu schaffen, durch den der Flascheninhalt vor unbefugter Manipulation sicherer gemacht wird und der unbefugte Manipulationen leichter erkennbar macht.The invention is therefore based on the object of providing a tamper-evident closure for gas bottle valves, by means of which the contents of the bottle are made safer from unauthorized manipulation and which makes unauthorized manipulations more easily recognizable.

Diese Aufgabe ist erfindungsgemäß gelöst mit den im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved with the features specified in the characterizing part of claim 1. Advantageous developments of the invention are specified in the subclaims.

Der Erfindung liegt somit der Gedanke zugrunde, den Ventilanschlußstutzen mit einem Einwegverschluß zu schützen, der bei Entfernung zerstört wird und Manipulationen sofort erkennen läßt. Insbesondere, wenn der Originalitätsverschluß aus einem Material hergestellt ist, welches sich bei Zerstörung des Verschlußes aufspreizt, läßt sich ein Manipulations­versuch sofort erkennen.The invention is therefore based on the idea of protecting the valve connecting piece with a one-way closure, which is destroyed when removed and tampering can be recognized immediately. In particular, if the tamper-evident closure is made of a material that spreads when the closure is destroyed, an attempt at manipulation can be recognized immediately.

Die Ziele der Erfindung ließen sich auch durch das Anbringen einer Plombe erreichen. Dies ist aber eine verhältnismäßig teure Maßnahme, die beim serienmäßigen Abfüllen der Flaschen stören würde. Außerdem lassen sich Plomben verhältnismäßig leicht fälschen. Die Ver­wendung des erfindungsgemäßen Originalitätsverschlußes kann dagegen vom Hersteller mit hoher Sicherheit kontrolliert werden. Eine Nachahmung oder Fälschung ist nur mit sehr hohen Kosten möglich. Darüberhinaus bietet der erfindungsgemäße Originalitätsverschluß den Vorteil, daß auf ihm leicht eine Produktinformation angebracht werden kann, sei es direkt auf dem Ver­ schluß oder auf einem an diesen befestigten Zettel. Erfahrungsgemäß erreichen derartige Produktinformationen häufig nicht den Anwender, wenn sie separat mitge­liefert werden oder lose an der Flasche befestigt sind.The objects of the invention could also be achieved by attaching a seal. But this is a relatively expensive measure that would interfere with the standard filling of the bottles. Seals are also relatively easy to forge. The use of the tamper-evident seal according to the invention, however, can be controlled with a high degree of certainty by the manufacturer. Imitation or counterfeiting is only possible at very high costs. In addition, the tamper-evident closure according to the invention has the advantage that product information can be easily attached to it, be it directly on the ver close or on a note attached to it. Experience has shown that such product information often does not reach the user if it is supplied separately or if it is loosely attached to the bottle.

Zwei Ausführungsbeispiele der Erfindung sollen anhand der beigefügten Zeichnungen erläutert werden.Two embodiments of the invention will be explained with reference to the accompanying drawings.

Es zeigen:

  • Fig. 1 einen Querschnitt durch ein Gasflaschenventil in Höhe des Ventilstutzens mit angelegtem Originalitätsverschluß,
  • Fig. 2 eine Ansicht A-A von Figur 1,
  • Fig. 3 die gleiche Ansicht wie Figur 2, jedoch ohne Ventil,
  • Fig. 4 einen Querschnitt durch einen Originalitäts­verschluß für Flaschenventile mit auf dem Ventilstutzen aufgeschraubter Verschlußmutter,
  • Fig. 5 eine Ansicht B-B von Figur 4,
  • Fig. 6 die gleiche Ansicht wie Figur 4, jedoch mit in Höhe des Anschlußstutzens geschnittenem Gas­flaschenventil und
  • Fig. 7 eine Ansicht C-C von Figur 6.
Show it:
  • 1 shows a cross section through a gas cylinder valve at the level of the valve socket with a tamper-evident closure,
  • 2 is a view AA of Figure 1,
  • 3 shows the same view as FIG. 2, but without a valve,
  • 4 shows a cross section through a tamper-evident closure for bottle valves with a closure nut screwed onto the valve stub,
  • 5 is a view BB of Figure 4,
  • Fig. 6 shows the same view as Figure 4, but with a gas bottle valve cut at the level of the connecting piece and
  • 7 is a view CC of Figure 6.

Der in den Figuren 1 bis 3 dargestellte Originalitäts­ verschluß 1 umgibt ein Gasflaschenventil 2 in Höhe des Gasflaschenventil-Anschlußstutzens 3. Der Originalitätsverschluß 1 ist im wesentlichen als Band mit einem T-förmigen Profil ausgebildet. Das T-förmige Profil ist lediglich am Gelenk 4 unterbrochen. Das Material des Originalitätsverschlußes 1 ist Kunststoff. Der gesamte Originalitätsverschluß 1 wird als ein­teiliges Kunststofformteil in der Weise hergestellt, daß der die Spitze 5 tragende Arm des Bandes im un­belasteten Zustand um 180° um das Gelenk 4 zurückge­klappt ist. Infolgedessen spreizt sich der Originalitäts­verschluß 1 auf, wenn er gewaltsam geöffnet wird oder an einer beliebigen Stelle durchtrennt wird. Der Originalitätsverschluß 1 wird geschlossen, indem die an einem Ende des Bandes angeordnete, als Widerhaken ausgebildete Spitze 5 in die an das andere Bandende angeformte Aufnahmehülse 6 gedrückt wird. Das Öffnen des Verschlußes erfolgt gewaltsam durch Ziehen an der Abreißlasche 7, wodurch die Spitze 5 abreißt und der Verschluß zerstört wird. Im Bereich des Gasflaschen­ventil-Anschlußstutzens 3 besitzt das Band eine Kappe 8 mit einer Verschlußplatte 9, welche den Gasflaschen­ventil-Anschlußstutzen 3 umgibt und gegen Verunreini­gungen und Beschädigungen schützt. Die Verschlußplatte 9 wird durch Stege 10 gehalten, Kappe 8 und Verschluß­platte 9 können jedoch auch geschlossen ausgebildet sein. Um eventuell austretendes Gas sicher abzuleiten, ist es jedoch vorteilhafter, die Verschlußplatte 9 durch Stege 10 zu halten.The originality shown in Figures 1 to 3 Closure 1 surrounds a gas cylinder valve 2 at the level of the gas cylinder valve connecting piece 3. The tamper-evident closure 1 is essentially designed as a band with a T-shaped profile. The T-shaped profile is only interrupted at the joint 4. The material of the tamper-evident closure 1 is plastic. The entire tamper-evident closure 1 is produced as a one-piece molded plastic part in such a way that the arm of the band carrying the tip 5 is folded back by 180 ° around the joint 4 in the unloaded state. As a result, the tamper-evident closure 1 expands when it is opened by force or is severed at any point. The tamper-evident closure 1 is closed by pressing the tip 5, which is arranged at one end of the band and is designed as a barb, into the receiving sleeve 6 formed on the other end of the band. The closure is opened violently by pulling on the tear-off tab 7, as a result of which the tip 5 tears off and the closure is destroyed. In the area of the gas bottle valve connector 3, the band has a cap 8 with a closure plate 9, which surrounds the gas bottle valve connector 3 and protects against contamination and damage. The closure plate 9 is held by webs 10, but the cap 8 and closure plate 9 can also be designed to be closed. In order to safely discharge any escaping gas, however, it is more advantageous to hold the closure plate 9 by means of webs 10.

Der in den Figuren 4 bis 7 dargestellte Originalitäts­verschluß 11 unterscheidet sich von dem in den Figuren 1 bis 3 dargestellten Originalitätsverschluß 1 ledig­ lich dadurch, daß er zum Anbringen an ein Gasflaschen­ventil 2 geeignet ist, dessen Gasflaschenventil-An­schlußstutzen 3 durch eine Verschlußmutter 12 mit Kette 13 verschlossen ist. Für gleiche Teile wurden daher die gleichen Bezugsziffern verwendet. Zur Sicherung des Gasflaschenventil-Anschlußstutzens 3 und der Ver­schlußmutter 12 besitzt der Originalitätsverschluß 11 eine die Verschlußmutter 12 umgebende Halbschale 14. Statt der Halbschale 14 könnte auch eine geschlossene Kappe wie bei dem Originalitätsverschluß 1 vorgesehen werden, dies bereitet jedoch Schwierigkeiten bei der Herstellung als einteiliges Kunststofformteil. Die Halbschale 14 besitzt einen Schlitz 15, durch welchen die Kette 13 geführt ist.The tamper-evident seal 11 shown in FIGS. 4 to 7 differs from the tamper-evident seal 1 shown in FIGS. 1 to 3 only Lich in that it is suitable for attachment to a gas cylinder valve 2, the gas cylinder valve connector 3 is closed by a lock nut 12 with chain 13. The same reference numerals have therefore been used for the same parts. To secure the gas bottle valve connecting piece 3 and the locking nut 12, the tamper-evident closure 11 has a half-shell 14 surrounding the locking nut 12. Instead of the half-shell 14, a closed cap as with the tamper-evident closure 1 could also be provided, but this creates difficulties in the production as a one-piece plastic molded part . The half-shell 14 has a slot 15 through which the chain 13 is guided.

Nach Entfernen des Originalitätsverschlußes 1 bzw. 11 verbleiben keinerlei Rückstände am Gasflaschenventil 2 und zur Wiederbefüllung der Gasflasche sind keinerlei Zusatzarbeiten erforderlich. Selbstverständlich ist die Erfindung nicht auf die beiden in den Figuren 1 bis 7 dargestellten Ausführungsbeispiele beschränkt. Sowohl der Verschluß aus Spitze 5 und Aufnahmehülse 6 als auch die Ausbildung der Kappe 8 bzw. der Halb­schale 14 können anders gestaltet sein. Desgleichen ist es nicht erforderlich, den Originalitätsverschluß 1 bzw. 11 als einteiliges Kunststofformteil herzu­stellen, obwohl dies die bevorzugte Ausführungsform ist.After removing the tamper-evident seal 1 or 11, no residues remain on the gas bottle valve 2 and no additional work is required to refill the gas bottle. Of course, the invention is not limited to the two exemplary embodiments shown in FIGS. 1 to 7. Both the closure of the tip 5 and the receiving sleeve 6 and the design of the cap 8 or the half-shell 14 can be designed differently. Likewise, it is not necessary to produce tamper-evident closure 1 or 11 as a one-piece plastic molding, although this is the preferred embodiment.
