Definitions

  • the invention relates to a security adhesive flap that undergoes irreversible, visually perceptible changes at the latest after detachment from a surface, in particular of paper or cardboard, when re-gluing.
  • an adhesive tab serves to join two pieces of flat material by adhering each one end to one of the pieces.
  • An adhesive flap which can not be manipulated unnoticed is to be referred to below as a security adhesive flap. It is particularly suitable as an anti-theft device for outer packaging (hereinafter also referred to as packaging) in which a plurality of individual packages are combined.
  • packaging an anti-theft device for outer packaging (hereinafter also referred to as packaging) in which a plurality of individual packages are combined.
  • packaging transport packaging for cigarette rods, smaller electronic devices and pharmaceutical products may be mentioned.
  • the security adhesive tab In order to effectively form a tamper evident closure for packaging, particularly paper or paperboard, the security adhesive tab must be adhered to at least two butt or overlapping packaging parts such that removal of at least one of the packaging parts is required to open the package ,
  • adhesive tapes with a suitable length for closing a package should be referred to as an adhesive flap.
  • the JP-A-09-176990 discloses, for example, an adhesive tape which consists of a pigment-containing layer with an adhesive portion and a protective layer above it.
  • the protective layer When removing the tape, the protective layer However, the adhesive layer remains partially stuck to the protective layer and partially on the packaging, ie the pigment-containing layer is visibly damaged and re-sticking is subsequently clearly visible.
  • the disadvantage here is in particular the need for special adhesives, which must be introduced into the pigment-containing layer.
  • a layer structure for an adhesive label consisting of a weakened lines intermediate layer of an adhesive layer and a continuous top film which is applied by means of adhesive on the line provided with weakening lines.
  • the top film holds the label parts together and creates a smooth and easy to print surface.
  • an adhesive label consisting of an adhesive layer and a film degradation with at least one layer which is injured by means of a laser beam, but not cut through.
  • Suitable for this purpose is a polyester film called, which has a sufficient tensile strength and heat stability in order to keep the film structure stable.
  • the material of the film layer adjoining the adhesive layer and the adhesive are selected such that a repositionability of the adhesive label, preferably for about half an hour, is possible.
  • the degree of weakness of the line of weakness ie in particular the removal depth is material dependent and thickness-dependent chosen so that the adhesive label can be donated without destruction risk on the object to be adhered, a repositioning without damaging the adhesive label is guaranteed and after complete development of the adhesive layer, the adhesive label in the region of the line of weakness uncontrollably ruptures when attempting to remove the adhesive label.
  • a laser-sensitive layer should be provided in addition to the weakened by laser radiation film layer. This can advantageously be introduced into the weakenable film layer, a line of weakness as well as a label in the laser-sensitive layer in one operation.
  • An adhesive label after the DE 103 46 683 A1 which is to serve both for identification and as security closure, must, as explained, have a special film structure of at least two layers or in the case of only one layer, a marking can only be done by the additional step of printing.
  • the invention is based on the object to provide a method for producing a security adhesive flap from a commercially available, self-adhesive packaging tape and a non-reusable security adhesive flap.
  • a security gluing bag 1 consists of one piece of commercial packaging adhesive tape with a laser-workable material backing layer 2 and an adhesive layer 3 which is made up to a suitable length to abut it over two package parts 4a, 4b of a package abutting one another or one another overlap, such. B. two on one side of a carton opposite flaps to stick.
  • the carrier layer 2 there is at least one slit 5 of a constant width which completely cuts through the carrier layer 2.
  • the slots 5 may be open on both sides, whereby the security adhesive flap 1 is divided into several parts. Likewise, the slots 5 may be closed on one or both sides, whereby the parts of the security adhesive flap 1 adjoining the slots 5 remain connected to one another.
  • the slots 5 may be introduced running along lines whose course represent an identifier, for. As a lettering or a barcode.
  • the slits 5 are introduced by means of a laser scanner, wherein the process parameters are set such that the slits 5 are produced with a single scan in a predetermined slit profile and have a width which defines the slits 5 in the surface structure of the carrier layer 2 make visually and / or tactilely perceptible. It is clear to the person skilled in the art that the generation of the slots 5 is also possible by guiding a laser head along the slot course. Likewise, the package can be moved to a fixed laser head to effect the necessary relative movement at a predetermined feed rate between the tool (laser beam) and the workpiece (package with safety adhesive flap).
  • the slot profile and the slot width of the slots 5 form a reproducible slot geometry. On the one hand, it must be preserved in order not only to be able to perceive the slots 5 and, if necessary, to reliably recognize an identifier determined by the slot geometry and, on the other hand, to be able to infer manipulations from visual and / or tactile perceptible changes in the slot geometry. It can be introduced an identifier that is visually and / or tactile recognizable.
  • an identifier is selected, which is perceptible, but without aids not recognizable, z. As a barcode, which makes it difficult to attempt the imitation of the identifier.
  • the safety adhesive flap 1 is first positioned on its intended location and then slit with laser.
  • a packaging adhesive tape was used with a carrier layer 2 of polypropylene with a natural rubber portion and an adhesive layer 3 of acrylate.
  • the slot geometry is formed by three juxtaposed, extending over the width of the security adhesive flap 1 slots 5.1 in the form of zigzag lines.
  • the security adhesive flap 1 is formed from four parts separated from each other. Even if it should be possible to remove the individual parts undamaged from the surface of the two packaging parts 4a, 4b, they can not do so again are placed so that the slots 5.1 form an identical slot geometry.
  • the two intermediate parts respectively bounded by the zigzag lines can not be applied over their unstretched length by the concertina effect.
  • Fig. 2b is shown a further advantageous slot geometry. It is formed by a plurality of mutually different, but defined spaced, rectilinear slots, which in connection represent a bar code.
  • the isolated or still connected parts of the security adhesive flap 1 can not be detached without the carrier layer 2 being overstretched. Even slight overstretching results in the fact that the safety adhesive flap 1 can not be repositioned practically, but theoretically, not with its original slot structure.
  • a length of an adhesive flap determining length is separated from a packaging adhesive tape with a carrier layer 2 made of a laser-processable material and an adhesive layer 3, suitable for sealing packaging made of paper or paperboard.
  • the adhesive flap is then glued over at least two packaging parts 4a, 4b of a package so that the package can only be opened undamaged if the adhesive flap is removed from at least one of the packaging parts 4a, 4b.
  • one or more slits 5 which completely cut through the carrier layer 2 are introduced into the carrier layer 2 by means of a laser.
  • the slots 5 form by their course and their width and optionally their arrangement to each other a certain slot geometry. The introduction of the slots 5 takes place by a unique, the slot geometry descriptive relative movement between the laser beam and adhesive flap, which from the adhesive flap a security adhesive flap 1 is.
  • a continuously emitting CO 2 laser can be used.
  • the slot geometry can also be generated by a plurality of lasers and the relative movement can also be a combined movement of the laser and the packaging.
  • the relative movement is generated solely by a controlled scanning movement of the laser.
  • the process parameters, in particular the laser power, the scanning speed and the feed rate, are selected such that the carrier layer 2 is completely penetrated by a single sweep of the slot structure, but at the same time the packaging parts 4a, 4b underneath remain unhurt.
  • carrier layer 2 Other materials for the carrier layer 2 include other plastics, such as PVC or polyester, but also paper in question, which advantageously have a natural rubber content.
  • adhesive layer 3 moreover, in particular hot-melt adhesives are suitable.
  • the carrier layer 2 and the adhesive layer 3 may also be made to form a packaging adhesive tape which is a wet-stick tape.
