Definitions

  • the invention relates to a closure label which has its underside applied to a package, e.g. Film or carton packaging, such as a tubular bag package, flow wrap packaging, carton, blister package, and / or adhesive closure to close the package, the closure label having an opening zone for opening the closure about a predetermined bending area and a braking zone adjoining it along a predetermined boundary area, in which the label is captive on the closure or packaging.
  • a package e.g. Film or carton packaging, such as a tubular bag package, flow wrap packaging, carton, blister package, and / or adhesive closure to close the package
  • the closure label having an opening zone for opening the closure about a predetermined bending area and a braking zone adjoining it along a predetermined boundary area, in which the label is captive on the closure or packaging.
  • the braking zone is formed by either an adhesive brake or a stamped brake.
  • the label is coated in the region of the opening zone with a more easily removable adhesive, but in the braking zone with a much stronger adhesive, in particular hot glue.
  • hot-melt adhesives When hot-melt adhesives are used, they tend to yellow and lose their flexibility and adhesion over time, particularly under UV irradiation.
  • the printed image of the label is affected by the curved, about wavy punching. Furthermore, the label can distort when opening, so that a clean reclosure of the package is only conditionally possible. Because these labels are single-layered, the stiffness of the flexure area and the rest of the label in the opening and braking zones can not be independently defined. On the one hand, the label should have a certain inherent rigidity, so that it automatically reseals when resealed, but on the other hand, a lower stiffness is required in the bending area in order to clearly define the bending range.
  • the pressure-sensitive adhesive can be dragged through the punching tool into the label material or, over time, the pressure-sensitive adhesive can emerge from the punched seam on the upper side and contaminate the label, which is also called adhesive bleeding ,
  • the object of the invention is therefore to provide a closure label which is easy to manufacture and does not accidentally dissolve in the braking area.
  • the tensile force acting on the braking zone during folding from the bending area is distributed over the area of the braking zone, also in the direction away from the bending area to the border area, so that the bond between Braking zone and packaging or closure is subjected to only a shearing force while preventing starting from the braking area on the bond between the braking zone and the packaging or closure a peel force acts.
  • the bending area and the border area form mutually parallel lines, whereby the appearance of the label is hardly impaired.
  • the border region is defined by a section extending from the bottom to a portion of its thickness, such as a punched through. This can optionally be carried out in one step with the punching required of the label circumference which is required in any case and allows a clear definition of the border region, for example in the form of a straight line, with little effort.
  • the closure label preferably has at least one first layer and a second layer fixedly connected to the upper side thereof, the predetermined boundary region between the opening zone and the braking zone being defined by a transection of the first layer, while the second layer is left continuous.
  • This multilayered design leads to the possibility that the firm connection between the first layer and the second layer in one the detachment zone extending from the transection of the first layer into the braking zone is at least partially released, wherein the edge of the detachment zone lying in the braking zone defines the predetermined bending region.
  • the bending range can be clearly defined with little effort, for example in the form of a straight strip whose edges are parallel to each other.
  • the partial solution of the bond in the release zone can be facilitated, for example, by bonding the first layer to the second layer but, in the release zone, luting or neutralizing the bond.
  • this adhesion may be stronger than that with which the first layer adheres to the closure on the closure, for manufacturing reasons particularly simple, the underside of the label with a continuous adhesive layer, in particular pressure-sensitive adhesive layer to be provided which extends over both the opening zone and the braking zone.
  • This adhesive layer may be continuous throughout, or possibly also screened or otherwise patterned.
  • the first and second layers are each formed from plastic films bonded together by a laminating adhesive layer, this laminating adhesive adhering more strongly than the pressure-sensitive adhesive layer with which the label is adhered to the package.
  • the stiffness of the second layer may be equal to, greater, or less than that of the first layer, achieved by selecting different materials for the two layers and / or by making the layers of different thicknesses be made. For example, if the second layer is stiffer than the first layer, the label flips itself down when releasing the opening zone around the bending area; if the second layer is softer, the label will remain open when released.
  • a grip tab at the end remote from the braking area, which is preferably non-adhesive on the underside, i.e. the pressure-sensitive adhesive is recessed, glued over or otherwise neutralized there.
  • the label material can be punched at the border between the opening zone and grip tab at its lowermost area to a portion of its thickness.
  • the bending region or the recess of the laminating adhesive may be concealed from above, for example, by making the material of the second layer itself opaque, and / or by an overprint applied thereto.
  • the closure label only at its one end region on a pairing of bending and boundary area, while at the remote end of a grip tab can be provided.
  • This label can only be folded up in one direction.
  • the closure label can have a respective pairing of bending and boundary regions on at least two opposite end regions, and optionally also a grip tab on both end regions. If this label is lifted up at one end region, the pair of bending and boundary regions adjoining this end are easily detached from the substrate by peeling force, while further peeling is avoided at the opposite other end by the displacement of the bending region and boundary region according to the invention In the braking zone, the label sticks firmly to the surface due to shearing force on the adhesive. However, the label can also be lifted from the other side in the same way, with the same mechanism of action, only in the opposite direction from the other to the first end.
  • the label can thus be from both ends Fold it up while it remains captively secured at the other end of the package or the closure, which makes the operation of the closure particularly simple, without a higher manufacturing cost and higher production costs are required.
  • Another advantage is that such a label can be opened equally easily by a left-handed and a right-handed person.
  • the closure label may have a grip tab at both opposite end regions.
  • the label is not completely punched through, but partially, the initially mentioned adhesive bleeding on the surface of the label is prevented. Since the pressure sensitive adhesive of the label can be identical for both the opening zone and for the braking zone, the label material can be manufactured and processed inexpensively.
  • the bending area is designed as a linear zone with mutually parallel boundary edges, the label can be opened and closed without distorting or deforming the label, while the thickness or the material selection of the uppermost first layer can define the restoring force along the bending area.
  • a precursor may be prepared or provided wherein on a carrier web, e.g. siliconized paper over which the first layer of adhesive is applied.
  • a carrier web e.g. siliconized paper over which the first layer of adhesive is applied.
  • This first layer of the precursor is pierced from the side remote from the carrier web, for the preparation of the separation zone separating the opening zone from the braking zone, and then the laminating adhesive layer is applied, leaving the detachment zone.
  • the second layer is attached, and optionally printed and covered again with a laminating film.
  • a plurality of labels are circumferentially punched from the composite material thus formed, and the remaining grid remaining between the labels is removed, so that only the labels adhere to the carrier material, for example for further processing in a labeling machine.
  • the precursor may be supplied as a separate product, or may be prepared online in one pass with the further construction of the composite.
  • Fig. 1 and 2 show an approximately rectangular in plan view, but at the corners rounded closure label 1, which is applied via a pre-applied continuously on its underside surface pressure sensitive adhesive layer 3 together on a package 5 - such as a foil or cardboard packaging - and the closure tab 7 is glued to the closure flap 7 on the packaging 5 lying flat to keep closed.
  • the closure label 1 carries a grip tab 11, the underside of which carries no pressure-sensitive adhesive. From the one end 9 to opposite the other end 13 towards the closure label 1 is divided into an opening zone 15 and a braking zone 17, wherein a major part of the surface of the closure label 1 is occupied by the opening zone 15, while the braking zone 17 occupies only a narrow strip along the other end 13.
  • the opening direction of the closure label 1 is in Fig. 1 indicated by the arrow A.
  • the closure label 1 has, seen in section, a base material layer (first layer) 19 coated on its underside with the pressure-sensitive adhesive 3 and a cover material layer (second layer) 23 connected to its upper side via a laminating adhesive layer 21.
  • the two layers 19 and 23 consist here of plastic film, wherein the selection of materials is not particularly limited, such as PP (polypropylene), PE (polyethylene) or mixtures thereof, or other materials.
  • the base material layer 19 may, for example, be 20-60 ⁇ m thick, while the cover material layer 23 may have a thickness of 40-50 ⁇ m. In principle, however, other materials and thicknesses come into question, such as paper.
  • the pressure-sensitive adhesive layer may be applied at 16-22 g / m2, while the laminating adhesive layer 21 can be kept very thin, about 2-6 ⁇ m. The laminating adhesive layer 21 adheres more strongly than the pressure-sensitive adhesive layer 3.
  • opening zone 15 and braking zone 17 The boundary between opening zone 15 and braking zone 17 is defined by a linear punch-through 25 of only the base material layer 19 together with pressure-sensitive adhesive 3, which extends transversely to the opening direction A, but does not cut through the covering material layer 23. From this punching 25 away toward the other end 13 in the braking zone 17 is in a strip-shaped separation region 27, the base material layer 19 is not connected to the cover material layer 23, here by recess of Kaschierklebstoffs 21.
  • This separation region 27 defines a kink or Bending zone, around which the opening zone 15 folds up when folding up, while the braking zone 17 adheres to the closure 7.
  • the pressure-sensitive adhesive 3 is released from the package 5 by peeling force in the region of the opening zone 15 so that the opening zone 15 can be lifted off with little effort.
  • the cover material layer 23 bends up in the detachment region 27, while the tensile force transmitted from the cover material layer 23 to the base material layer 19 via the laminating adhesive 21 is influenced by the edge 29 adjacent to the other end 13 Transfer zone 27 is distributed down to the pressure-sensitive adhesive layer 3 is transferred, even at an oblique angle from this edge 29 to the punching 25 out (see arrows B in Fig. 3 ).
  • the peeling of the pressure-sensitive adhesive layer 3 ends at the punch-through 25, and substantially only a shearing force acts on the pressure-sensitive adhesive layer 3, whereby the pressure-sensitive adhesive layer 3 can not be detached from the closure 7, at least without significantly increased expenditure of force, since the bond has high shear forces withstand, but only small peeling forces.
  • the opening zone 15 is adhered to the package 5 and the braking zone 17 on the closure 7, in principle it is also possible to stick the braking zone 17 on the package 5 and the opening zone 15 on the closure 7, after opening the label, this now remains captive on the package 5.
  • the label has only two plastic layers, namely the base material layer 19 and the cover material layer 23, other layers may also be arranged on the top or bottom of at least one of the two layers 19 and 23, or between them.
  • At least one of the two layers 19 and 23 may be printed on the top and / or bottom side.
  • the base material layer 19 is punched at a parting line 31 in order to facilitate the lifting of the grip tab 11.
  • Fig. 4 to 7 show another embodiment of the closure label 1 ', wherein the first embodiment analogous features are provided with the same reference numerals, and a detailed description thereof is omitted.
  • This closure label 1 ' carries in addition to the grip tab 11 and at the other end 13 a second grip tab 11'. Further, in addition to the braking region 17 of the first embodiment near the one end 9 of the closure label V 'still a second brake area 17' is provided, which is mirror-symmetrical to the first braking area 17, with a punch-through 25 ', a subsequent separation zone 17' and a to an end 9 facing edge 29 'of this separation zone 27'.
  • This closure label 1 ' can be folded up on both sides and is therefore equally easy to use for both right-handed and left-handed, as from the comparison 6 and 7 shown, where Fig. 7 the folding direction of the first execution of Fig. 3 matches, but Fig. 6 the opposite folding direction around the second detachment zone 27 'around towards the first end 9 back.
  • Fig. 8 shows a closure label similar to the first embodiment, which is releasably adhered to a carrier web T.
  • the carrier web T it may be to Example to act siliconized paper on which a plurality of such labels 1 adhere to each other and are transmitted from there for example with a labeling on the packaging.
  • the closure label 1 according to the invention is produced, for example, such that the pressure-sensitive adhesive layer 3 is first printed onto the carrier web T and the base material layer 19 is fastened thereon.
  • the composite thus prepared may be supplied separately or made in one pass with the following processing steps.
  • the punch-through 25 which separates the later opening zone 15 from the braking zone 17, as well as the parting line 31 on the grip tab 11 from the side remote from the carrier web T side into the base material layer 19 is punched.
  • laminating adhesive layer 21 is applied, leaving the detachment zone 27 empty, and then the covering material layer 23 is applied thereon.
  • the cover material layer 23 may be previously printed on the top and / or bottom, and preferably so that the transfer zone 27 is covered invisibly from above by the imprint.
  • the imprint 33 can also be applied after the application of the covering material layer 23, in which case a further transparent laminating layer 35 can be applied which protects the imprint 33.
  • the laminating adhesive 21 may, for example, be a UV-curing laminating adhesive.
  • the covering material layer 23 should be transparent and unprinted so that the UV rays 21 can penetrate through to the laminating adhesive layer 21, and only then can the imprint 33 and the further coating 35 be applied when the UV irradiation has been completed.
  • the Fig. 9 to 13 show various non-limiting embodiments of packaging on which the closure label 1 according to the invention is respectively mounted.
