Definitions

  • the invention relates to a tamper-evident closure for gas cylinder valves.
  • the invention is therefore based on the object
  • 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 tamper-evident closure is made of a material that spreads when the closure is destroyed, an attempt at manipulation can be recognized immediately.
  • 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.
  • 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.
  • 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.
  • 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.
  • the tamper-evident closure according to the invention has the advantage that product information can be easily added to it.
  • 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.
  • 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.
  • the twist-off toggle designed as a barb which is molded onto the shell 2
  • 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.
  • 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.
  • 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 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.
