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 a cap (3) made of plastic, which can be placed on the glass-bottle valve connection piece and which has a retaining ring (6). The inner surface of the retaining ring is shaped conically and engages behind in the manner of a barb the end of thread of the glass-bottle valve connection piece. The retaining ring is connected to the edge of the cap by means of bridges (8). The bridges serve as predetermined breaking points. <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 by 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 erkannbar macht.The invention is therefore based on the object 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 angegeben 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.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.

Die Verwendung des erfindungsgemäßen Originalitätsver­schlusses kann vom Hersteller mit hoher Sicherheit kon­trolliert werden. Eine Nachahmung oder Fälschung ist nur mit sehr hohen Kosten möglich.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.

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 auf enen Gasflaschenventil-­Anschlußstutzen aufgesetzten Origi­nalitätsverschluß im Schnitt,
  • Fig.2 einen Originalitätsverschluß mit Abdrehknebel und
  • Fig.3 eine teilweise geschnittene Seiten­ansicht des Originalitätsverschlusses von Fig.2.
Show it:
  • 1 shows a tamper-evident closure placed on a gas bottle valve connecting piece, in section,
  • 2 shows a tamper-evident closure with a twist-off knob and
  • 3 shows a partially sectioned side view of the tamper-evident closure of FIG. 2.

Fig.1 zeigt den Gasflaschenventil-Anschlußstutzen 1 eines Gasflaschenventils 2. Auf den Gasflaschenventil-­Anschlußstutzen 1 ist ein Originalitätsverschluß auf­gesetzt. Erfindungsgemäß besteht dieser aus einer Kappe 3 aus Kunststoff. Der Boden der Kappe 3 kann flach aus­gebildet sein. Er kann aber auch, wie hier dargestellt, als Verschlußplatte 4 geformt sein, die mittels einer konischen Anformung direkt die Öffnung des Gasflaschen-­Anschlußstutzen verschließt und durch Stege mit der Wand 5 der Kappe 3 verbunden ist. Eventuell austreten­des Gas kann durch die Öffnungen zwischen den Stegen sicher abströmen.1 shows the gas bottle valve connection piece 1 of a gas bottle valve 2. An originality closure is placed on the gas bottle valve connection piece 1. According to the invention, this consists of a cap 3 made of plastic. The bottom of the cap 3 can be flat. However, it can also, as shown here, be shaped as a closure plate 4, which closes the opening of the gas bottle connecting piece directly by means of a conical formation and is connected to the wall 5 of the cap 3 by means of webs. Any escaping gas can safely escape through the openings between the webs.

Erfindungsgemäß ist an die Kappe 3 ein Haltering 6 mit konisch geformter Innenfläche angeformt. Der Haltering 6 hinterfaßt den Gewindeauslauf 7 des Gasflaschenven­til-Anschlußstutzens 1 infolge seiner konischen Innen­fläche wie ein Widerhaken. Als Verbindung zwischen Hal­tering 6 und Kappe 3 dienen Brücken 8, die zugleich Sollbruchstellen darstellen.According to the invention, a retaining ring 6 with a conically shaped inner surface is molded onto the cap 3. The retaining ring 6 grips the threaded outlet 7 of the gas cylinder valve connecting piece 1 due to its conical inner surface like a barb. Bridges 8, which also represent predetermined breaking points, serve as the connection between the retaining ring 6 and the cap 3.

Beim Aufsetzen der Kappe 3 verbiegt sich der Haltering 6, so daß er leicht über das Gewinde 9 des Gasflaschen­ventil-Anschlußstutzens 1 gleitet. Ein Abnehmen ist je­doch nicht mehr möglich, da sich der Haltering 6 im Gewindeauslauf 7 verhakt. Der Originalitätsverschluß läßt sich nur abnehmen, wenn die Brücken 8 zerstört werden.When the cap 3 is put on, the retaining ring 6 bends so that it slides easily over the thread 9 of the gas cylinder valve connecting piece 1. However, removal is no longer possible, since the retaining ring 6 hooks into the thread runout 7. The tamper-evident seal can only be removed if the bridges 8 are destroyed.

Die Fig.2 und 3 zeigen eine andere Ausführungsform des Originalitätsverschlusses, die sich von der Ausfüh­rungsform gemäß Fig.1 dadurch unterscheidet, daß die Wand 5 und der Haltering 6 einen gemeinsamen Spalt auf­weisen. In dem Spalt ist mittels Brücken 10, die eben­falls als Sollbruchstellen dienen, ein Abdrehknebel 11 befestigt. Diese Ausführungsform hat den Vorteil, daß sich beim Aufsetzen des Originalitätsverschlusses der Haltering 6 besonders leicht verformen kann. Zum Abneh­men des Originalitätsverschlusses wird lediglich der Abdrehknebel 11 entfernt. Von Vorteil ist hierbei auch, daß zugleich der Haltering 6 mit entfernt wird, die Brücken 8 müssen also nicht unbedingt alle zerstört werden. Sie können daher auch stärker oder als zusam­menhängende Ringfläche ausgebildet sein.2 and 3 show another embodiment of the tamper-evident closure, which differs from the embodiment according to FIG. 1 in that the wall 5 and the retaining ring 6 have a common gap. A twist-off toggle 11 is in the gap by means of bridges 10, which also serve as predetermined breaking points attached. This embodiment has the advantage that when the tamper-evident closure is put on, the retaining ring 6 can deform particularly easily. To remove the tamper-evident closure, only the calibration toggle 11 is removed. It is also advantageous here that the retaining ring 6 is also removed at the same time, so the bridges 8 do not necessarily all have to be destroyed. They can therefore also be made stronger or as a coherent ring surface.

Weder zum Aufsetzen noch zum Abnehmen des erfindungsge­mäßen Originalitätsverschlusses sind Werkzeuge erfor­derlich. Er kann leicht als Kunststofformteil herge­stellt werden. Eine Herstellung aus Metall wäre zwar auch möglich, aber zu teuer.Tools are not required for fitting or removing the tamper-evident closure according to the invention. It can be easily manufactured as a molded plastic part. Manufacture from metal would also be possible, but would be too expensive.
