Abstract

The system has a tamper proof locking system (2) with a pulling tab (3) mounted on a cutting tool introducing space (4) that is formed by an opening (11) or a thermoformed cavity (8). The tab initiates the opening of a package (1) by lifting a precut part for permitting the access to a content of the package after the tab is cut by a cutting tool e.g. knife. The tab is welded on a shell of the package and presents a tear resistance greater than that of the shell of the package, where the tab has information (10) e.g. pictogram, explaining opening of the system.

Description

Objet de l'inventionObject of the invention

La présente invention se rapporte aux systèmes d'ouverture des emballages en coques rigides et en particulier à un système d'ouverture facilitée d'un emballage en coques plastiques thermoformées au moyen d'une languette de traction verrouillée sur l'emballage, ladite languette constituant une amorce pour tirer sur une partie prédécoupée facilitant l'accès au contenu de l'emballage tout en garantissant l'inviolabilité de celui-ci par des moyens ordinaires.The present invention relates to systems for opening packages in rigid shells and in particular to a facilitated opening system of a package made of thermoformed plastic shells by means of a pull tab locked on the package, said tab constituting a primer for pulling a pre-cut portion facilitating access to the contents of the package while ensuring the inviolability of the latter by ordinary means.

Etat de la techniqueState of the art

Les emballages en coques rigides sont habituellement difficiles à ouvrir car les coques sont souvent soudées entre elles et n'ont pas d'amorce d'ouverture car les surfaces commerciales souhaitent intentionnellement protéger le contenu contre le vandalisme ou le vol.Rigid shell packaging is usually difficult to open because the hulls are often welded together and have no opening primer because commercial surfaces wish to intentionally protect the contents against vandalism or theft.

La conséquence en est que lorsque l'acheteur d'un produit emballé dans ce type d'emballage se retrouve à la maison pour le déballer, il doit faire intervenir des outils coupants en ne sachant généralement pas très bien de quel côté entamer l'ouverture de la coque.The consequence is that when the buyer of a product packaged in this type of packaging is found at home to unpack it, it must involve cutting tools by not knowing very well on which side to open the opening of the hull.

Différents inventeurs ont essayé d'appréhender ce problème en créant des initiations facilitant l'ouverture de ce type d'emballage sans cependant se préoccuper de l'inviolabilité de ceux-ci. Parmi les documents divulguant ce type d'initiations à l'ouverture, on peut citer les documents FR 2433469 , EP 0844193 A1 et WO 96/20882 .Various inventors have tried to apprehend this problem by creating initiations facilitating the opening of this type of packaging without however worrying about the inviolability of these. Among the documents disclosing this type of initiations to the opening, we can mention the documents FR 2433469 , EP 0844193 A1 and WO 96/20882 .

Parmi les documents qui tentent à la fois de résoudre la problématique de l'ouverture et l'inviolabilité, on peut citer les documents FR 2751632 et FR 2800046 .Among the documents that attempt to solve the problem of openness and inviolability are the documents FR 2751632 and FR 2800046 .

Le document FR 2800046 divulgue un emballage à coque thermoformée réutilisable qui est constitué d'une feuille de base possédant une prédécoupe et sur laquelle est scellée une coque destinée à contenir le produit à emballer. Pour le déballage, on plie la feuille, dégageant ainsi un appendice qui une fois coupé à l'aide de ciseaux, donne accès au produit emballé. Ce type d'emballage convient très bien pour des objets de petite taille comme les mèches ou autres petits outils. Il ne convient cependant pas pour des objets de taille supérieure tels que des sèche-cheveux, des rasoirs, des épilateurs, des brosses à cheveux. On ne voit pas très bien comment un objet de grande taille pourrait être ouvert de cette façon puisque « l'appendice » deviendrait très grand et cela reviendrait à devoir découper toute une partie de la coque de l'emballage et donc finalement à ne pas bénéficier d'une facilité d'ouverture.The document FR 2800046 discloses a reusable thermoformed shell package which consists of a base sheet having a precut and on which is sealed a shell for containing the product to be packaged. For unpacking, the sheet is folded, thus releasing an appendage which when cut with scissors, gives access to the packaged product. This type of packaging is very suitable for small objects such as bits or other small tools. However, it is not suitable for larger objects such as hair dryers, razors, epilators, hairbrushes. It is unclear how a large object could be opened in this way since "the appendage" would become very large and that would amount to having to cut a whole part of the hull of the packaging and thus finally not to benefit an ease of opening.

Le document FR 2751632 divulgue une ouverture facilitée de conditionnements ou d'emballages en coques PVC au moyen d'une languette témoin d'inviolabilité sur prédécoupe, sans arrachages ni déchirures blessantes de matières. Il est constitué d'une languette témoin à découper suivant un pointillé pour permettre de soulever et de tirer sur la partie prédécoupée de l'emballage. Après avoir découpé la languette témoin, la partie prédécoupée ne semble cependant pas facile d'accès pour autant que ce détail important soit visible dans ce document.The document FR 2751632 discloses an easier opening of packaging or packaging in PVC shells by means of a tamper evident tamper evident tab, without tearing or tearing injuries of materials. It consists of a control tab to cut out a dotted line to allow to lift and pull on the pre-cut part of the package. After cutting the control tab, the pre-cut part does not seem easy to access as long as this important detail is visible in this document.

Buts de l'inventionGoals of the invention

La présente invention vise à surmonter les inconvénients de l'état de la technique et en particulier à fournir un moyen d'ouverture simple d'un emballage en coques, sans aucune restriction quant à la taille de l'objet à emballer, tout en garantissant l'inviolabilité de cet emballage dans les surfaces commerciales.The present invention aims to overcome the disadvantages of the state of the art and in particular to provide a means of simple opening of a package in shells, without any restriction as to the size of the object to be packaged, while ensuring the inviolability of this packaging in commercial areas.

Description détaillée de l'inventionDetailed description of the invention

La présente invention divulgue un emballage en coques 1 comportant un système de verrouillage inviolable 2 témoin d'un conditionnement intact. Le système de verrouillage comporte une languette de tirage rapportée 3 qui, une fois coupée, permet l'accès à une partie de l'emballage bénéficiant d'un tracé prédécoupé et donnant accès au contenu de l'emballage.The present invention discloses a shell package 1 having a locking system inviolable 2 witness of intact packaging. The locking system comprises an attached pull tab 3 which, once cut, allows access to a portion of the package having a pre-cut pattern and giving access to the contents of the package.

Pour faciliter l'ouverture du verrou 2 par découpe de la languette de tirage 3, celle-ci enjambe un espace d'introduction d'un outil de coupe 4 tel qu'un couteau ou une paire de ciseaux. L'espace 4 en question peut être simplement une ouverture perforée 11 ou une cavité thermoformée 8, chacune réalisée au moment de la fabrication de l'emballage. Cet espace 4 doit évidemment être d'une dimension suffisante pour permettre l'introduction d'un outil de coupe 9.To facilitate the opening of the latch 2 by cutting the pull tab 3, it straddles a space for introduction of a cutting tool 4 such as a knife or a pair of scissors. The space 4 in question can be simply a perforated opening 11 or a thermoformed cavity 8, each made at the time of manufacture of the package. This space 4 must obviously be of sufficient size to allow the introduction of a cutting tool 9.

Lorsque le tracé prédécoupé 6 est constitué par une tirette entourant l'ensemble de l'emballage, la languette de tirage, une fois libérée de son verrou, permet d'ouvrir toute la coque de l'emballage en parcourant par exemple le contour d'e celle-ci près de la soudure 12 (voir figure 1). Une telle tirette peut cependant également être placée sur n'importe quelle autre partie plate de la coque pour accéder à son contenu (voir figure 2).When the pre-cut pattern 6 is constituted by a zipper surrounding the entire package, the pull tab, once released from its lock, can open the entire shell of the package by browsing for example the contour of This is near the weld 12 (see Figure 1). Such a zipper can however also be placed on any other flat part of the shell to access its contents (see Figure 2).

La languette de tirage 3 faisant partie du verrou inviolable 2 peut être réalisée en n'importe quelle matière résistante à la déchirure. Sans être exhaustif, celle-ci peut être réalisée en fibres synthétiques tissées ou non tissées de polymères résistant à des efforts de traction ou de déchirure susceptibles d'être produits lorsqu'une personne tenterait de tirer sur ladite languette pour accéder à l'emballage sans l'avoir au préalable déverrouillé avec un outil de coupe 9.The pull tab 3 forming part of the tamper-proof lock 2 can be made of any tear-resistant material. Without being exhaustive, it may be made of synthetic fibers woven or non-woven of polymers resistant to tensile or tearing forces that may be produced when a person attempts to pull on said tongue to access the packaging without have it unlocked beforehand with a cutting tool 9.

Dans la présente demande, le terme « rapporté» signifie ne faisant pas partie intégrante du matériau utilisé pour réaliser la coque de l'emballage au départ de sa fabrication. Ceci permet notamment un grand choix de matériaux utilisables à la fois pour la coque et pour la languette de tirage 3.In this application, the term "reported" means that it is not an integral part of the material used to make the shell of the package departure from its manufacture. This allows in particular a large choice of materials that can be used both for the shell and for the pull tab 3.

La languette de tirage 3 peut être fixée sur l'emballage 1 pour former le verrou 2 de différentes manières et notamment par soudure et par adhésif permanent.The pull tab 3 can be fixed on the package 1 to form the latch 2 in different ways and in particular by welding and permanent adhesive.

La languette 3 pourra évidemment comporter toute une série d'informations comme des messages publicitaires ou des pictogrammes d'aide à l'ouverture, ou encore être réalisée dans une couleur ostensible permettant au client de reconnaître immédiatement l'avantage du système.The tongue 3 can obviously include a variety of information such as advertising messages or pictograms of assistance to the opening, or be made in an ostensible color allowing the customer to immediately recognize the advantage of the system.
