Description

Die Erfindung betrifft einen Klebfolienstreifen-Verbund und seine Verwendung, nämlich einen solchen mit einem Klettverschluß und einem Klebfolienstreifen, der durch Ziehen in Richtung der Verklebungsebene abstripbar ist.The invention relates to an adhesive film strip assembly and its use, namely one with a Velcro fastener and an adhesive film strip, which can be stripped off by pulling in the direction of the bond plane.

Klebfolien, die durch Ziehen in der Verklebungsebene wiederablösbar sind, sind bekannt und im Handel erhältlich, so als "Power Strips"@ von der Beiersdorf AG.Adhesive films that can be removed by pulling in the bonding plane, are known and commercially available, such as "Power Strips" @ from the Beiersdorf AG.

So beschreibt US 4,024,312 ein Selbstklebeband mit einem dehnbaren und elastischen Träger aus einem Blockcopolymeren, insbesondere für Anwendungen im medizinischen Bereich, wo ein schmerzloses Abziehen von der Haut erwünscht ist. No. 4,024,312 describes a self-adhesive tape with a stretchable and elastic carrier made of a block copolymer, in particular for applications in the medical field where painless removal from the skin is desired.

Weiterhin beschreibt DE 33 31 016 A1 eine Klebfolie für wiederlösbare Klebbindungen, die es gestattet, daß eine damit hergestellte Klebbindung durch Ziehen an der Klebfolie in Richtung der Verklebungsebene lösbar ist. Mit solchen Klebfolien lassen sich hohe Klebkräfte und Scherfestigkeiten erzielen und Klebverbunde ohne weitere Hilfsmittel wieder lösen, vergleichbar dem Öffnen eines Weckglases, ähnlich wie dort die Gummidichtung am Anfasser aus der Dichtungsfuge gezogen wird. Furthermore, DE 33 31 016 A1 describes an adhesive film for releasable adhesive bonds, which allows an adhesive bond produced therewith to be released by pulling on the adhesive film in the direction of the bond plane. With such adhesive films, high adhesive strengths and shear strengths can be achieved and adhesive composites can be released again without further aids, comparable to opening a mason jar, similar to how the rubber seal on the handle is pulled out of the sealing joint.

Ferner beschreibt DE 37 14 453 C1 einen zerstörungsfrei von Übungsobjekten wieder abnehmbaren Übungssprengkörper, der mit einer Klebfolie reversibel befestigt wird.Furthermore, DE 37 14 453 C1 describes a training explosive device which can be removed again without destruction from training objects and which is reversibly fastened with an adhesive film.

Auch WO 92111333 beschreibt unter anderem Klebfolien für entsprechende Anwendungen, wobei die eingesetzten Klebfolien eine geringe Elastizität bei gleichzeitig hoher Dehnung aufweisen. WO 92111333 also describes, inter alia, adhesive films for corresponding applications, the adhesive films used having low elasticity and high elongation at the same time.

DE 42 22 849 C1 beschreibt ebenfalls einen Streifen einer Klebfolie dieser Art mit einem besonders ausgestalteten Anfasser.DE 42 22 849 C1 also describes a strip of an adhesive film of this type with a specially designed handle.

Schließlich beschreiben DE 42 33 872 C2 und WO 94121157 wiederablösbare selbstklebende Haken, die ebenfalls mit derartigen Klebfolien ausgerüstet und also wiederablösbar sind.Finally, DE 42 33 872 C2 and WO 94121157 describe removable self-adhesive hooks which are also equipped with such adhesive films and are therefore removable.

Weitere Klebfolienstreifen dieser Art werden in WO 95/06691, DE 43 39 604 A1, DE 44 28 587 A1 und DE 44 31 914 A1 beschrieben, und eine entsprechende Aufhängevorrichtung in DE 195 11 288 A1. Further adhesive film strips of this type are described in WO 95/06691, DE 43 39 604 A1, DE 44 28 587 A1 and DE 44 31 914 A1 , and a corresponding suspension device in DE 195 11 288 A1.

Die in den vorgenannten Druckschriften dargestellten Klebstoffsysteme wiesen jedoch auch eine Anzahl von Nachteilen auf:

  • Um die Klebfolie aus der Klebfuge herauslösen zu können, muß ein Teil derselben in Form eines Anfassers aus dieser hervortreten. Die Klebfolie ist damit notwendigerweise bei der Verklebung nicht flexibler Gegenstände nicht völlig unsichtbar, sondern der Anfasser ist sichtbar, welches optisch unvorteilhaft erscheinen kann und bei Verwendung von Materialien, welche unter Lichteinfluß altern, auch zu technischen Problemen führen kann.
  • Beim Verkleben kann es leicht dazu kommen, daß die gesamte Klebfolie, also inklusive Anfasser, in der Klebfuge verschwindet. Besonders dem Laien kann dies passieren, wann er einen Abschnitt einer solchen Klebfolie nicht so am Rande des Substrates plaziert, daß ein Anfasser übersteht und dann aus der Klebfuge herausragt. Beim Lösen der Verklebung ist dann guter Rat teuer und ein Zerstören zumindest des einen Substrates kann die Folge sein.
  • Tritt ein Reißen der Klebfolie beim Ablöseprozeß auf und verbleibt ein gerissener Klebfolienteil vollständig in der Klebfuge, so ist eine rückstandsfreie Trennung der verklebten Materialien ohne Zerstörung der Verklebungspartner zumeist nicht mehr möglich, welches einen erheblichen Schaden verursachen kann.
However, the adhesive systems shown in the aforementioned publications also had a number of disadvantages:
  • In order to be able to detach the adhesive film from the adhesive joint, some of the adhesive must emerge from it in the form of a handle. The adhesive film is thus not necessarily completely invisible when non-flexible objects are bonded, but the handle is visible, which can appear optically disadvantageous and can also lead to technical problems when using materials that age under the influence of light.
  • When gluing, it can easily happen that the entire adhesive film, including the handle, disappears in the adhesive joint. This can happen to laypersons in particular if they do not place a section of such an adhesive film on the edge of the substrate in such a way that a handle protrudes and then protrudes from the adhesive joint. When releasing the bond, good advice is then expensive and the destruction of at least one substrate can result.
  • If the adhesive film tears during the detachment process and a torn adhesive film part remains completely in the adhesive joint, a residue-free separation of the bonded materials without destroying the bonding partners is usually no longer possible, which can cause considerable damage.

Auch die in DE 195 11 288 beschriebene Aufhängevorrichtung hat Nachteile, indem ein Verkleben lediglich auf festen, möglichst glatten und insbesondere ebenen Untergründen bzw. Substraten möglich ist.The suspension device described in DE 195 11 288 also has disadvantages, by gluing only to firm, as smooth as possible and in particular flat substrates or substrates is possible.

In der WO-A-95/35056 wird beschrieben, wie ein Klettverschluß dazu dient, Gegenstände, wie zum Beispiel Schilder, aus einem Untergrund aus Gewebe oder Gestrick reversibel zu befestigen.WO-A-95/35056 describes how a Velcro fastener serves to Objects, such as signs, from a surface made of fabric or Reversible fastening of knitted fabric.

So bleibt es ein ungelöstes Problem, wie denn wertvolle oder solche Gegenstände, die unbeschädigt bleiben sollen, insbesondere nicht angebohrt werden sollen, reversibel, rückstandsfrei wiederlösbar und beschädigungslos auf unebenen oder sonst ungünstigen Substraten zu befestigen seien.So it remains an unsolved problem, like valuable or such items, that should remain undamaged, especially not drilled should be reversible, removable without residue and damage-free on uneven surfaces or other unfavorable substrates.

Demgemäß betrifft die Erfindung einen Klebfolienstreifen-Verbund und seine Verwendung, wie dies im einzelnen in den Ansprüchen gekennzeichnet ist.Accordingly, the invention relates to an adhesive film strip composite and its Use as characterized in detail in the claims.

Bezüglich der einzusetzenden Klettverschlüsse und Klebfolienstreifen wird auf den Stand der Technik verwiesen.Regarding the Velcro fasteners and adhesive tape strips to be used referred to the state of the art.

Die Ablösung der verklebten Gegenstände wird dabei durch die Dehnung des doppelseitigen Haftklebebandes erreicht. Der auftretende Adhäsionsverlust wird durch Verringerung der Klebrigkeit der Haftklebemasse analog DE 33 31 016 bzw. DE 42 22 849 begünstigt, sowie durch die Reduktion der Klebfoliendicke, verursacht durch die Dehnung der Klebstoff-Folie. The detachment of the glued objects is caused by the stretching of the double-sided adhesive tape reached. The loss of adhesion that occurs by reducing the stickiness of the PSA analogously to DE 33 31 016 or DE 42 22 849 favors, and by reducing the thickness of the adhesive film, caused by the stretching of the adhesive film.

Bei Verwendung von Klebfolien-Abschnitten mit einem Zwischenträger kommen insbesondere Produkte vom Typus wie in WO 92111333 in Betracht.When using adhesive film sections come with an intermediate carrier in particular products of the type as in WO 92111333.

Die Erzeugungsmöglichkeit der nicht haftklebrigen Bereiche für Anfasser sind vielfältig. Sie kann z.B. durch Inertisierung der Haftklebemasse mittels eines nicht klebrigen Lackes erfolgen. Weitere Möglichkeiten umfassen das Zukaschieren von dünnen Schichtmaterialien wie Kunststoff-Folien und Papieren.The possibility of creating the non-sticky areas for handles are diverse. It can e.g. by inerting the PSA using a non sticky paint. Other options include lamination of thin layer materials such as plastic films and papers.

Als Deckpapier oder Trennlaminate eignen sich die üblichen Trennfolien und Trennpapiere, z.B. silikonisierte Trennfolien/Trennpapiere, welche üblicherweise als gut trennende flächige Medien gegenüber Haftklebemassen eingesetzt werden.The usual release films and are suitable as cover paper or release laminates Release papers, e.g. siliconized release films / release papers, which are usually can be used as a good separating flat media compared to PSAs.

Generell sei zu Herstellung, Verarbeitung und Handhabung von den besonders bevorzugten Klebfolien auf DE 33 31 016, DE 42 22 849 und WO 92111333 verwiesen.In general, the manufacture, processing and handling of the special preferred adhesive films on DE 33 31 016, DE 42 22 849 and WO 92111333 directed.

In mehrfacher Hinsicht reversibel lassen sich erfindungsgemäß Substrate verbinden, nämlich zum einen über den Klettverschluß, zum anderen über den oder die Klebfolienstreifen.According to the invention, substrates can be reversible in several respects connect, namely on the one hand via the Velcro, on the other hand via the or the adhesive film strips.

Vorteilhafte Anwendungen sind insbesondere solche mit unebenen Substraten, etwa im Automobilbereich, wie am Armaturenbrett oder auf Seitenverkleidungen, etwa ein Handy. Aber auch sonstige gerundete Gegenstände, wie Vasen, Bälle, Kleidungsstücke und auch der menschliche oder tierische Körper lassen sich so reversibel und beschädigungslos bekleben.Advantageous applications are in particular those with uneven substrates, for example in the automotive sector, such as on the dashboard or on side panels, like a cell phone. But also other rounded objects, such as vases, Leave balls, items of clothing and also the human or animal body stick to itself so reversibly and undamaged.

Vorteilhaft ist dabei auch eine Version mit zwei Anfassern an einem Klebfolienstreifen, gemäß EP 747 027 A2.A version with two handles on an adhesive film strip is also advantageous, according to EP 747 027 A2.

Auch sonstige schwierige Substrate lassen sich erfolgreich reversibel und beschädigungslos verkleben und wieder lösen, wie Fliegengitter vor Fenstern, Teppiche auf schwierige Untergründe, wobei auch solche Teppiche geeignet sind, die bereits eine Schlaufen-Rückseite aufweisen, so daß nur noch der Haken-Teil eines Klettverschlusses eingesetzt werden muß.Other difficult substrates can also be reversibly and successfully glue and undamage without damage, like fly screens in front of windows, Carpets on difficult surfaces, whereby such carpets are also suitable are, which already have a loop back, so that only the hook part a Velcro fastener must be used.

Im folgenden soll die Erfindung anhand von Zeichnungen erläutert werden, ohne sie aber unnötig einschränken zu wollen. Es zeigen:

Fig. 1:
eine schematische Seitenansicht eines erfindungsgemäßen Verbundes, und
Fig. 2:
eine schematische Seitenansicht eines Verbundes gem. Fig. 1, verklebt auf Substraten und auseinandergezogen.
In the following, the invention will be explained with reference to drawings, but without wishing to restrict it unnecessarily. Show it:
Fig. 1:
is a schematic side view of a composite according to the invention, and
Fig. 2:
a schematic side view of a composite acc. Fig. 1, glued to substrates and pulled apart.

Im einzelnen zeigt Fig. 1 einen Klebfolienstreifen-Verbund 1 aus einem ersten Klebfolienstreifen 2, der an seiner einen Klebseite mit einer Abdeckfolie 3 eingedeckt ist, während auf seiner anderen Klebseite ein Schlaufen-Klettband 4 so klebt, daß die Rückseite an dem Klebfolienstreifen 2 grenzt und die Vorderseite mit ihren Schlaufen 5 mit den Haken 6 eines entsprechenden Haken-Klettbandes 7 verhakt ist. Dieses Haken-Klettband 7 wiederum ist mit seiner Rückseite auf eine der Klebseiten eines zweiten Klebfolienstreifens 8 geklebt, wobei dessen andere Klebseite wiederum mit einer Abdeckfolie 9 eingedeckt ist. Die Klebfolienstreifen 2 und 8 weisen an ihren Enden mit Folien 10/11 abgedeckte Bereiche auf, die als Anfasser 12/13 dienen.1 shows an adhesive film strip composite 1 from a first Adhesive film strip 2, which has a cover film 3 on its one adhesive side is covered, while on its other adhesive side a loop Velcro tape 4 sticks so that the back borders on the adhesive film strip 2 and the front with their loops 5 with the hooks 6 of a corresponding hook-and-loop tape 7 is hooked. This hook and loop tape 7 is in turn with its back glued to one of the adhesive sides of a second adhesive film strip 8, wherein whose other adhesive side is in turn covered with a cover sheet 9. The Adhesive film strips 2 and 8 have at their ends covered with films 10/11 Areas that serve as handles 12/13.

In Fig. 2 ist nun dargestellt, wie ein Verbund 1 gem. Fig. 1, befreit von seinen Abdeckfolien 3/9, einerseits auf ein Substrat 14 und andererseits auf ein Substrat 15 geklebt ist, wobei der Klettverschluß geöffnet ist, d.h. das Haken-Klettband 7 ist von dem Schlaufen-Klettband 4 gelöst, so daß die Schlaufen 5 und die Haken 6 frei liegen und die Substrate 14 und 15 mit den daran haftenden Verbundteilen voneinander frei sind, im Sinne des Doppelfoils A aber auch wieder verbindbar sind. Um aber die Substrate 14 bzw. 15 von dem Verbundteil zu befreien (dazu ist vorteilhaft der Verbund im Sinne von Fig. 2 gelöst), lassen sich die Klebfolienstreifen 2 und 8 durch Ziehen an den Anfassern 12 und 13 in Richtung der Pfeile A und C, also in Richtung der Verklebungsebene, rückstandsfrei und beschädigungslos abziehen und zumindest der Klettverschluß 4 und 8 wieder verwenden.In Fig. 2 it is now shown how a composite 1 acc. Fig. 1, exempt from his Cover foils 3/9, on the one hand on a substrate 14 and on the other hand on a substrate 15 is glued with the Velcro fastener open, i.e. the hook and loop tape 7 is released from the loop Velcro 4, so that the loops 5 and the hook 6 are exposed and the substrates 14 and 15 with the composite parts adhering to them are free from each other, but can also be reconnected in the sense of double foils A. are. But to free the substrates 14 and 15 from the composite part (see if the composite is advantageously solved in the sense of FIG. 2), the adhesive film strips can be 2 and 8 by pulling on the handles 12 and 13 in the direction of Arrows A and C, i.e. in the direction of the bond plane, residue-free and undamaged pull off and at least use Velcro 4 and 8 again.
