Definitions

  • the invention relates to a tamper-evident marking for a compressed gas cylinder, on the neck ring of which a protective cap can be detachably attached, comprising a marking ring formed from at least two segments arranged in a ring in the intended installation state between an end face of the protective cap and a shoulder of the neck ring of the compressed gas cylinder. which is equipped with at least one predetermined breaking point.
  • Compressed gas cylinders which are usually made of steel or aluminum and are used for storing compressed gases and liquids, are marked in accordance with legal requirements by a gas-specific paint and a sticker on the gas content.
  • some suppliers also attach a label with crack marks, which is positioned overlapping on the protective cap and the compressed gas cylinder neck.
  • plugs made of plastic are in use, which are plugged onto the connection thread of the cylinder valve. You have a predetermined breaking point, which should tear when removing the plug. Such plugs work in practice very poorly. The presence or the integrity of this sticker or this plug is used to indicate the original state after filling in the supplier.
  • the originality marking described therein comprises an identification ring, which is positioned on the neck ring, and which is provided with at least two predetermined breaking points.
  • the identification ring preferably made of a plastic injection molded part also has one or more identification flags, which may include information on the origin and / or content of the compressed gas cylinder, such as company name, logo, year of the next test, etc.
  • this object has the disadvantage that the ring is not securely fixed in its intended position and there is a risk that he already moved when screwing the cap from its position and squeezed laterally out of the gap between the neck ring and cap, causing the Function of the predetermined breaking point is no longer ensured.
  • Another tamper-evident device for steel bottles comprising a multi-segment ring clamped between a flanged edge of the steel bottle neck ring and an end face of a protective cap.
  • the ring segments are connected by means of connecting links via predetermined breaking points.
  • the predetermined breaking points are destroyed and the ring segments are connected only via tooth profiles with each other, which dissolve when removing the cap from each other and let the ring disintegrate into its individual segments.
  • the tooth profiles prevent premature detachment of the identification ring from the neck ring.
  • the predetermined breaking points do not break completely and / or the individual ring segments connecting tooth profiles caught together and hold the Kenracesring even with removed cap on the neck ring and thus fake a originality that is actually no longer available.
  • the invention is therefore based on the object to provide a tamper evidence for compressed gas cylinders, which overcomes the disadvantages of the prior art.
  • the profile element has a pressing surface which protrudes from the ring plane and two limbs connecting in each case at least in sections to the contact surface with one end of one of the segments and extending from the contact surface in the direction of the ring plane.
  • one of the two limbs can be in a shape which promotes elasticity, e.g. in the form of an "S", be carried out, whereby the ring elements when opening safely separate from each other.
  • the tamper-evident marking comprises an identification ring constructed from a plurality of ring segments, the ring segments being spaced apart from one another in the direction of rotation, forming a gap. Adjacent segments are connected to each other via profile elements with which the gap between the segments is bridged.
  • the profile elements comprise a here referred to as contact surface portion which rests in the application, ie when placing or screwing the cap on the end face of the cap or on the shoulder of the neck ring, and two each outgoing from this leg.
  • Each of the legs connects the contact surface with the end of one of the segments separated from each other by the gap.
  • the protective cap With the release of the protective cap, these forces are eliminated, the broken at the or breaking point / n originality marking detached from the neck ring and indicates a user that the bottle has already been opened.
  • a positive connection between the segments, or the segments and the profile element for example, made according to the tongue and groove principle, so that the originality marking remains in place until the protective cap is released.
  • the originality marking according to the invention thus ensures a simple, inexpensive and tamper-proof marking for all common compressed gas cylinders. Moreover, it is by no means necessary for the functionality of the originality marking according to the invention to break all intended breaking points in the application, it is usually sufficient to break one or fewer predetermined breaking points in order to ensure that the marking ring is detached from the neck ring when the protective cap is unscrewed solves and thus indicates the lack of originality of the bottle.
  • the identification ring is made in one piece, preferably made of injection molding.
  • the plastic material used in this case should have a certain elasticity to ensure easy attachment of the originality marking on the neck ring and the function of resetting the positive connection. Also advantageous is the use of a biodegradable plastic as a material, which ensures that fallen pieces of the identification ring does not permanently pollute the environment.
  • the predetermined breaking point arranged in the contact surface or a leg of the profile element Weak zone includes.
  • a weak zone may be, for example, a notch or a section of reduced material thickness in the contact surface or in one or both of the legs, or the profile element may comprise zones due to a specific geometry with respect to the pressure exerted by the protective cap on the identification ring have a lower breaking strength than the surrounding areas, such as a kink.
  • the zone at which a leg abuts the contact surface or the ring segments can be designed at an angle, which is usually a lower stability in these zones with applied pressure.
  • a predetermined breaking point may also be a connection, for example a seam.
  • At least one of the legs is designed as an elastic spring element which deforms elastically upon application of a force acting perpendicular to the ring plane pressing force, however, after the elimination of the contact force at least partially returns to its original shape.
  • the spring force can also be effected by the choice of an elastic plastic material as a raw material for the originality marking.
  • one of the two legs is in a shape favoring the elasticity, for example in the form of an "S" executed.
  • a restoring force is generated during compression of the identification ring, which ensures that the ring elements when removing the cap, so after elimination of the contact force, safely separate from each other.
  • the tamper-evident marking comprises fixing means for detachably connecting the ends of the segments to one another and / or to the profile element.
  • fixative ensure that after placing or screwing the cap and the subsequent breakage of at least one predetermined breaking point, the tamper-evident between fixed neck ring and protective cap and detachment can be done only after removing the cap.
  • the fixing means have elements which are arranged in the segments and / or the profile element, and which cooperate with corresponding elements on the respective other segment or on the profile element to produce a positive, but releasable after elimination of the contact force of the protective cap connection.
  • the fixing means are formed so that they produce a firm connection between the segments under the action of a substantially perpendicular to the ring plane applied contact force (as is usually present after putting on or screwing the cap on the neck ring), when discontinuing the

  • the fixing means comprise, for example, mutually corresponding toothing profiles, which cooperate only under the action of the contact pressure.
  • the restoring force is preferably effected via elastic profile sections which deform upon application of the contact pressure force and at least partially return to their original shape when the contact force is removed, thus ensuring the positive connection of the fixing means, e.g. release the splines again.
  • the restoring force is effected in the manner previously described due to an elastic design of one or both legs of the profile elements.
