Abstract
Description
Ruban adhésif double face de sécurité
La présente invention a pour objet un ruban adhésif double face permettant la mise en évidence de la séparation ou de l'ouverture par effraction des substrats que ledit ruban adhésif réunissait ou fermait.Double-sided safety tape
The subject of the present invention is a double-sided adhesive tape enabling the separation or break-in opening of the substrates which said adhesive tape joined or closed to be demonstrated.
On connaît de US 4876123 un ruban adhésif de sécurité dont le support lamifié se sépare en deux parties lors de l'arrachage en laissant apparaître un indice indicateur de l'ouverture.Known from US 4876123 is a security adhesive tape, the laminated support of which separates into two parts during the tearing off, revealing an indicator indicative of the opening.
Le ruban adhésif double face de sécurité selon l'invention se distingue de l'art antérieur par le fait qu'il est constitué d'un support monocouche clivable.The double-sided security adhesive tape according to the invention differs from the prior art in that it consists of a cleavable monolayer support.
Le ruban adhésif double face de sécurité selon l'invention est caractérisé en ce qu'il est constitué d'un support de faible cohésion, enduit sur chacune de ses deux faces de masse adhésive dont le pouvoir adhésif est supérieur à la cohésion du support.The double-sided security adhesive tape according to the invention is characterized in that it consists of a support of low cohesion, coated on each of its two faces with adhesive mass whose adhesive power is greater than the cohesion of the support.
La séparation et/ou l'ouverture est mise- en évidence par le clivage du support en deux parties ne pouvant se recoller sur elles-mêmes. En effet lorsqu'il y a tentative de décollement des substrats réunis par le ruban adhésif double face de sécurité, celui-ci ne se décolle par des substrats mais se divise selon un plan médian parallèle aux faces enduites de masse adhésive cn deux parties ne pouvant se recoller sur elles-mêmes. The separation and / or the opening is highlighted by the cleavage of the support in two parts which cannot be glued on themselves. In fact, when there is an attempt to peel off the substrates joined by the double-sided security adhesive tape, the latter does not peel off from the substrates but is divided along a median plane parallel to the faces coated with adhesive mass in two parts which cannot sticking back on themselves.
Ce clivable est rendu possible par l'utilisation d'une bande support dont la cohésion interne est inférieure au pouvoir adhésif du ruban sur les substrats sur lesquels il est collé.This cleavage is made possible by the use of a support strip whose internal cohesion is less than the adhesive power of the tape on the substrates on which it is bonded.
Suivant un mode de réalisation de l'invention le support est constitué d'une bande de mousse synthétique du type mousse d'emballage de faible cohésion due à une faible réticulation de la mousse. On utilisera ainsi avantageusement des mousses de polyéthylène ou de polyuréthane basse densité faiblement réticulées, des noii-tissés de faible cohésion et de façon génerale tout support permettant l'obtention d'une bande clivable en deux parties dans le sens de l'épaisseur.According to one embodiment of the invention, the support consists of a strip of synthetic foam of the packaging foam type with low cohesion due to low crosslinking of the foam. Advantageously, low-cross-linked polyethylene or low-density polyurethane foams, low-cohesion fabrics and generally any support allowing a cleavable strip to be obtained in two parts in the thickness direction will be used.
Selon un mode préféré de réalisation de l'invention la bande support a avant enduction une épaisseur comprise entre 0,5 mm et 1,5 mm.According to a preferred embodiment of the invention, the support strip has, before coating, a thickness of between 0.5 mm and 1.5 mm.
La bande support est alternativement enduite en surface de masse adhésive sur chacune de ses faces par les techniques d'enduction utilisées dans le domaine des adhésifs.The support strip is alternately coated on the surface with adhesive mass on each of its faces by the coating techniques used in the field of adhesives.
Les masses adhésives utilisées sont les masses adhésives connues de l'homme de l'art et par exemple une masse constituée d'un mélange d'élastomères de synthèse ct d'élastomères naturels.The adhesive masses used are the adhesive masses known to those skilled in the art and for example a mass consisting of a mixture of synthetic elastomers and natural elastomers.
Le ruban adhésif double face de sécurité est avantageusement protégé par des protecteurs antiadhérants, par exemple des protecteurs siliconés doubles faces permettant l'enroulement du ruban sur lui-même. The double-sided security adhesive tape is advantageously protected by non-stick protectors, for example double-sided silicone protectors allowing the tape to be wound on itself.
Afin de rendre la séparation et/ou l'ouverture par effraction plus visible on peut avantageusement tendre les masses adhésives enduites sur le support. En utilisant deux couleurs différentes, notamment des couleurs complémentaires, on obtient un ruban adhésif de couleur uniforme avant clivage, se séparant en de parties de couleurs différentes. On enduit par exemple une face d'une masse adhésive teinte en jaune et l'autre face d'une masse adhésive teinte en rouge ou en bleu. On obtient ainsi un ruban adhésif double face apparaissant coloré en vert ou en orangé avant clivage et se séparant en deux parties dont l'une sera colorée en jaune et l'autre en rouge ou en bleu.In order to make the separation and / or the break-in opening more visible, the adhesive masses coated on the support can advantageously be stretched. By using two different colors, in particular complementary colors, an adhesive tape of uniform color is obtained before cleavage, separating into parts of different colors. For example, one side is coated with an adhesive mass dyed yellow and the other side is coated with an adhesive mass dyed red or blue. This gives a double-sided adhesive tape appearing colored green or orange before cleavage and separating into two parts, one of which will be colored in yellow and the other in red or blue.
D'autres avantages et caractéristiques de l'invention seront mieux compris à la lecture de la description des figures annexées qui illustrent un mode de réalisation préféré de l'invention.Other advantages and characteristics of the invention will be better understood on reading the description of the appended figures which illustrate a preferred embodiment of the invention.

N/cm.The support 2 is a strip of extruded non-crosslinked polyethylene foam 1 mm thick. The force required to cleave this strip is 0.25
N / cm.
Les masses adhésives 3 et 4 sont constituées d'un mélange d'élastomères de synthèse et d ? élastomères naturels dont l'adhésivité sur le papier est de 0,4 N/cm (mesure de l'adhésivité selon la méthode A.F.E.R.A. (Association des Fabricants Européens de
Ruban Adhésif)). La masse adhésive 3 est teinte en bleu et la masse adhésive 4 est teinte en jaune. Le ruban 1 apparaît de couleur verte.The adhesive masses 3 and 4 consist of a mixture of synthetic elastomers and d? natural elastomers whose adhesiveness to paper is 0.4 N / cm (measurement of adhesiveness according to the AFERA method (Association of European Manufacturers of
Tape)). The adhesive mass 3 is dyed blue and the adhesive mass 4 is dyed yellow. Ribbon 1 appears green.
Un protecteur 5 siliconé sur ses deux faces protège le ruban et permet un enroulement sur lui-même.A silicone protector 5 on its two faces protects the ribbon and allows winding on itself.
Le ruban 1 est collé par la masse adhésive 3 au voisinage de la zone de fermeture d'un sachet 6, le protecteur 5 étant gardé en place afin d'éviter un collage accidentel du rabat de fermeture 7.The tape 1 is bonded by the adhesive mass 3 in the vicinity of the closure zone of a bag 6, the protector 5 being kept in place in order to avoid accidental sticking of the closure flap 7.
Pour sceller le sachet 6 on enlève le protecteur 5 et on applique avec une légère pression le rabat de fermeture 7 sur la masse adhésive 4.To seal the sachet 6, the protector 5 is removed and the closure flap 7 is applied with light pressure to the adhesive mass 4.
L'ouverture de sachet 6 clive le support 2 en deux parties 8 et 9. La partie clivée 8 apparat en bleu et la partie clivée 9 apparaît en jaune, mettant ainsi en évidence l'ouverture du sachet 6. Les parties clivées 8 et 9, non adhésives, ne peuvent pas se recoller sur elles-meme. The sachet opening 6 cleaves the support 2 into two parts 8 and 9. The cleaved part 8 appears in blue and the cleaved part 9 appears in yellow, thus highlighting the opening of the sachet 6. The cleaved parts 8 and 9 , non-adhesive, cannot be glued on themselves.
Le ruban adhésif double face selon l'invention trouve notamment application en tant que ruban adhésif de sécurité pour la fermeture et le scellement de plis confidentiels, d'emballages contenant des produits alimentaires ou pharmaceutiques et pour la fixation d'étiquettes ou de repères.The double-sided adhesive tape according to the invention finds particular application as a security adhesive tape for closing and sealing confidential folds, packaging containing food or pharmaceutical products and for fixing labels or markers.
Une autre utilisation de ce ruban adhésif double face est le collage temporaire de différents objets ou emballages devant être séparés rapidement et facilement sans détérioration desdits emballages.Another use of this double-sided adhesive tape is the temporary bonding of different objects or packages to be separated quickly and easily without deterioration of said packages.
La facilité de réalisation d'un tel ruban adhésif ainsi que son faible coût de revient sont d'autres avantages qui permettent de le distinguer des autres dispositifs et moyens permettant actuellement de garantir l'inviolabilité de systèmes de fermeture par collage. The ease of producing such an adhesive tape as well as its low cost are other advantages which make it possible to distinguish it from other devices and means currently making it possible to guarantee the inviolability of closure systems by bonding.
