Abstract

In some areas of application, there is the requirement to equip glass bottles with an origin-proof cap in such a manner that manipulations of the contents of the bottles can be recognised. This purpose is served by two shells (1, 2) which surround the valve and which are interconnected by means of at least two undetachable closures. Advantageously, the two shells are designed as a moulded plastic part and are interconnected by the dividing joint which is designed as a hinge (3). The edges which lie opposite the hinge are interconnected by means of a twist-off toggle (4) which is designed as a barb. <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 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.

Der Erfindung liegt daher die Aufgabe zugrunde, einenThe invention is therefore based on the object

Originalitätsverschluß für Gasflaschenventile zu schaf­fen, durch den der Flascheninhalt vor unbefugter Mani­pulation sicherer gemacht wird und der unbefugte Mani­pulationen leichter erkennbar macht.To create a tamper-evident closure for gas cylinder valves, which makes the contents of the cylinder more secure from unauthorized manipulation and which makes unauthorized manipulation easier to recognize.

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. Hierzu wird der erfindungsgemäße Originalitäts­verschluß bevorzugt als einteiliges Kunststofformteil ausgebildet. Die Teilungsfuge wird hierbei als Schar­nier ausgebildet und stellt einen der Verschlüsse dar. Die Schalen können aber auch separat und aus anderem Material hergestellt werden. Als Verschlüsse sind alle Verbindungen geeignet, die sich nach dem Zusammenfügen der Schalen nicht wieder öffnen lassen, ohne die Scha­len oder die Verschlüsse zu zerstören, also auch Kleb-­oder Schweißverbindungen und Plomben. Bevorzugt werden aber Verschlüsse, die beim Aneinanderdrücken der Scha­len unlösbar einrasten, insbesondere federnde, als Wi­derhaken ausgebildete Zungen auf der einen Schale, die in entsprechende Vertiefungen der anderen Schale ein­rasten. Die Befestigung des Originalitätsverschlusses kann dann ohne Hilfswerkzeuge von Hand erfolgen. Be­vorzugt werden die Schalen so dimensioniert, daß sie für alle gängigen Ventilvarianten verwendet werden können.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. For this purpose, the tamper-evident closure according to the invention is preferably designed as a one-piece plastic molding. The division joint is designed as a hinge and represents one of the closures. However, the shells can also be made separately and from other material. All connections that cannot be opened again after the shells have been joined together without destroying the shells or the closures, including adhesive or welded connections and seals, are suitable as closures. However, preference is given to closures which engage in a non-releasable manner when the shells are pressed against one another, in particular resilient tongues designed as barbs on one shell, which snap into corresponding recesses in the other shell. The tamper-evident closure can then be attached by hand without auxiliary tools. The shells are preferably dimensioned so that they can be used for all common valve variants.

Die Verwendung des erfindungsgemäßen Originalitätsver­schlusses kann vom Hersteller mit hoher Sicherheit kon­trolliert werden. Eine Nachahmung oder Fälschung ist nur mit sehr hohen Kosten möglich. Darüber hinaus bie­tet der erfindungsgemäße Originalitätsverschluß den Vorteil, daß ihm leicht eine Produktinformation beige­fügt werden kann.The manufacturer can control the use of the tamper-evident seal according to the invention with a high degree of certainty. 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 added to it.

Erfahrungsgemäß erreichen derartige Produktinformatio­nen häufig nicht den Anwender, wenn sie separat mitge­liefert werden oder lose an der Flasche befestigt sind.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.

Ein Ausführungsbeispiel der Erfindung soll anhand der beigefügten Zeichnungen erläutert werden.An embodiment of the invention will be explained with reference to the accompanying drawings.

Es zeigen:

  • Fig.1 die Vorderansicht eines als ein­teiliges Kunststofformteil ausge­bildeten Originalitätsverschlusses,
  • Fig.2 eine Seitenansicht von Fig.1 mit abgenommener linker Schale,
  • Fig.3 die Einzelheit "A" von Fig.1 ver­größert und im Schnitt,
  • Fig.4 eine Draufsicht auf die Einzel­heit "A" von Fig.3.
Show it:
  • 1 shows the front view of a tamper-evident closure designed as a one-piece plastic molded part,
  • 2 shows a side view of FIG. 1 with the left shell removed,
  • 3 the detail "A" of FIG. 1 enlarged and in section,
  • 4 shows a plan view of the detail "A" of Figure 3.

Der in den Fig.1 und 2 dargestellte Originalitätsver­schluß besteht aus den Schalen 1 und 2 aus Kunststoff, die als einteiliges Kunststofformteil ausgebildet sind. Hierzu ist die Teilungsfuge als Scharnier 3 ausgebildet. Dieses Scharnier stellt zugleich einen der nichtlösbaren Verschlüsse für die Schalen 1,2 dar. Der andere Ver­schluß ist als Abdrehknebel 4 ausgebildet, der detail­liert in den Fig.3 und 4 dargestellt ist. Sobald der als Widerhaken ausgebildete Abdrehknebel, welcher an die Schale 2 angeformt ist, in die entsprechende Öff­nung 5 der Schale 1 eingeführt ist, läßt sich der Verschluß nicht mehr zerstörungsfrei öffnen. Vielmehr muß zum Öffnen der Abdrehknebel 4 entfernt werden, wo­nach sich die Schalen 1,2 aufspreizen. Durch dieses Aufspreizen bzw. den fehlenden Abdrehknebel 4 lassen sich Manipulationen sofort erkennen.The tamper-evident closure shown in Figures 1 and 2 consists of the shells 1 and 2 made of plastic, which are designed as a one-piece molded plastic part. For this purpose, the division joint is designed as a hinge 3. This hinge is also one of the non-removable Closures for the shells 1, 2. The other closure is designed as a twist-off knob 4, which is shown in detail in FIGS. 3 and 4. As soon as the twist-off toggle designed as a barb, which is molded onto the shell 2, is inserted into the corresponding opening 5 of the shell 1, the closure can no longer be opened without being destroyed. Rather, to open the calibration toggle 4 must be removed, after which the shells 1,2 spread. Manipulations can be recognized immediately by this spreading apart or the missing twist-off knob 4.

Die Schalen 1,2 umgeben das Gasflaschenventil 6, wel­ches in die Gasflasche 7 eingeschraubt ist, allseitig. Die Schalen 1,2 werden vorzugsweise so dimensioniert, daß sie für alle gängigen Ventiltypen geeignet sind.The shells 1, 2 surround the gas bottle valve 6, which is screwed into the gas bottle 7, on all sides. The shells 1, 2 are preferably dimensioned so that they are suitable for all common valve types.

Die Schalen 1,2 schützen das Gasflaschenventil 6 weit­gehend vor Verunreinigungen und Witterungseinflüssen. Dies ist ein zusätzlicher Vorteil, wenn anstelle der üblichen Strahlkappen offene Schutzkörbe als Ventil­schutz verwendet werden.The shells 1, 2 largely protect the gas cylinder valve 6 from contamination and weather influences. This is an additional advantage if, instead of the usual jet caps, open protective cages are used as valve protection.

An die Schalen 1,2 kann ferner noch ein zusätzlicher Druckverschluß angeformt werden der es dem Kunden er­möglicht, den Originalitätsverschluß nach erfolgter Gasentnahme wieder anzubringen und dem Lieferanten zurückzugeben. Dies ist insbesondere dann von Vorteil, wenn der Originalitätsverschluß aus einem wiederver­wendbaren Kunststoff, z.B. Polypropylen, hergestellt wird.An additional pressure closure can also be molded onto the shells 1, 2, which enables the customer to re-attach the tamper-evident closure after gas removal and to return it to the supplier. This is particularly advantageous if the tamper-evident seal is made of a reusable plastic, e.g. Polypropylene.
