Description

PRODUIT STRATIFIE, PROCEDE POUR SA FABRICATION ETLAMINATE PRODUCT, PROCESS FOR MANUFACTURING SAME, AND

EMBALLAGE OBTENU A PARTIR DE CE PRODUIT  PACKAGING OBTAINED FROM THIS PRODUCT

La présente invention concerne un produit stratifié, mais également le procédé pour sa fabrication, ainsi que l'emballage obtenu à partir de ce produit stratifié.  The present invention relates to a laminated product, but also the process for its manufacture, as well as the packaging obtained from this laminate product.

Plus particulièrement, elle est destinée à la fabrication d'emballages sécurisés destinés aux envois postaux. Ce type d'emballage est généralement formé par une boîte en carton comportant des empreintes de pliage pour effectuer sa mise en forme.  More particularly, it is intended for the manufacture of secure packaging intended for postal items. This type of packaging is generally formed by a cardboard box with folding impressions for shaping.

Ce type de boîte comporte également des systèmes de fermeture composés bien souvent d'une languette de verrouillage anti-retour.  This type of box also includes closure systems often composed of a non-return locking tab.

L'ouverture s'effectue en arrachant cette languette.  Opening is done by pulling this tab.

Le problème essentiel dans ce type de boîte réside dans le fait de leur faible résistance à l'arrachement, ce qui facilite la violation de l'emballage pour en prélever son contenu, lors d'un acte de malveillance.  The main problem in this type of box lies in the fact of their low resistance to tearing, which facilitates the violation of the package to take its content, during an act of malicious intent.

Le but de l'invention est donc de réaliser un emballage carton résistant, avec éventuellement un témoin d'inviolabilité, de manière non seulement à augmenter la difficulté d'arrachement, mais également à laisser une trace visible en cas de tentative de déchirement.  The object of the invention is therefore to provide a strong cardboard packaging, possibly with a tamper evidence, so as not only to increase the difficulty of tearing, but also to leave a visible trace in case of attempted tearing.

La présente invention a pour but d'atteindre cet objectif, et concerne à cet effet un produit stratifié destiné notamment à la réalisation d'un emballage, caractérisé en ce qu'il est constitué : -d'une couche interne en carton; - d'une couche de colle; - d'une couche de fibres synthétiques, constituant une armature; - d'une couche de papier externe, de manière à réaliser un produit stratifié renforcé et à sécuriser le contenu de l'emballage.  The object of the present invention is to achieve this objective, and for this purpose concerns a laminated product intended in particular for the production of a package, characterized in that it consists of: a cardboard inner layer; - a layer of glue; a layer of synthetic fibers constituting an armature; - A layer of outer paper, so as to achieve a reinforced laminate product and secure the contents of the package.

Eventuellement la colle peut contenir des pigments ou analogues donnant une coloration en cas de déchirure, permettant de signaler que le carton a été ouvert ou qu'il a été tenté de l'ouvrir.  Optionally, the glue may contain pigments or the like giving a coloration in the event of a tear, making it possible to indicate that the carton has been opened or that it has been attempted to open it.

Un autre avantage de l'invention réside dans le fait que l'emballage étant réalisé à partir d'un flan en produit stratifié tel que défini ci- dessus, l'ensemble de l'emballage est ainsi protégé et renforcé à tout niveau, y compris celui de sa fermeture.  Another advantage of the invention lies in the fact that the packaging being made from a laminated product blank as defined above, the entire packaging is thus protected and reinforced at any level, including including that of its closure.

La présente invention concerne également les caractéristiques qui ressortiront au cours de la  The present invention also relates to features that will emerge during the course of the

description qui va suivre, et qui devront être  description which will follow, and which will have to be

considérées isolément ou selon toutes leurs combinaisons techniques possibles.  considered in isolation or in all their possible technical combinations.
