Definitions

  • the invention relates to a tamper-evident closure for gas cylinder valves.
  • 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.
  • 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.
  • 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.
  • FIG. 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.
  • 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.
  • 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.
  • 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.
  • FIG. 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.
  • 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.
