La présente invention a pour objet un dispositif de fermeture pour sacs ou emballages analogues, qui assure une fermeture inviolable tout en étant d'une ouverture facile. The present invention relates to a closure device for bags or similar packaging, which ensures tamper-evident closure while being easy to open.
Le dispositif de fermeture selon l'invention est caractérisé en ce qu'il est formé à partir d'une bande de carton ou matière semi-rigide analogue dont une face est enduite d'une matière adhésive par pression et est recouverte d'une feuille de protection anti-adhésive, une série d'éléments étant découpés dans la bande de carton alors que, dans la feuille de protection est découpé, au droit de chaque élément, une portion de largeur inférieure à celle de l'élément mais sensiblement de même longueur. The closure device according to the invention is characterized in that it is formed from a strip of cardboard or similar semi-rigid material, one face of which is coated with an adhesive material by pressure and is covered with a sheet. of non-stick protection, a series of elements being cut from the cardboard strip while, in the protective sheet is cut, in line with each element, a portion of width less than that of the element but substantially similarly length.
L'invention a également pour objet un emballage fermé à l'aide du dispositif ci-dessus, caractérisé en ce que l'embout en carton dont la partie médiane longitudinale est recouverte de la portion découpée dans la feuille de protection, est plié en deux et appliqué sur les bords de l'emballage de fagon que les parties non recouvertes par cette portion découpée ne fassent pas saillie par rapport à ces bords. The subject of the invention is also a package closed using the above device, characterized in that the cardboard end-piece whose longitudinal middle part is covered with the portion cut from the protective sheet, is folded in half and applied to the edges of the packaging so that the parts not covered by this cut portion do not protrude from these edges.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du dispositif selon l'invention, avec référence au dessin annexé dans lequel

Tel qu'il est représenté au dessin, le dispositif de fermeture de sac selon l'invention est formé à partir d'une bande de carton 1 dont une face est enduite d'une matière adhésive par pression 2. Sur cette face est appliquée une feuille de protection 3, par exemple en papier, qui comporte un revêtement anti-adhésif, par exemple siliconé. As shown in the drawing, the bag closure device according to the invention is formed from a strip of cardboard 1, one face of which is coated with an adhesive material by pressure 2. On this face is applied a protective sheet 3, for example made of paper, which has a non-stick coating, for example siliconized.
Dans la bande de carton 1 ont été découpés des éléments 4 qui sont rectangulaires dans l'exemple de réalisation représenté et restent reliés les uns aux autres par la feuille siliconée 3. In the cardboard strip 1 have been cut elements 4 which are rectangular in the embodiment shown and remain connected to each other by the silicone sheet 3.
La feuille siliconée 4 est elle-même découpée, au droit de chaque élément 4, suivant un profil rectangulaire 5 qui délimite une portion 6 de largeur inférieure à celle de l'élément 4, mais sensiblement de même longueur. The silicone sheet 4 is itself cut, in line with each element 4, along a rectangular profile 5 which delimits a portion 6 of width less than that of element 4, but substantially the same length.
L'ensemble comporte une ligne de pliage longitudinale médiane 7 et des ouvertures d'accrochage 8a et 8b symétriquement disposées par rapport à cette ligne 7. The assembly includes a median longitudinal fold line 7 and hooking openings 8a and 8b symmetrically disposed with respect to this line 7.
Pour fermer un emballage 9, on retire un élément 4 de la bande 1. La portion découpée 6 de la feuille siliconée reste attenante à l'élément 4 en laissant un vide 10 dans la feuille 3. To close a package 9, an element 4 is removed from the strip 1. The cut portion 6 of the silicone sheet remains attached to the element 4, leaving a void 10 in the sheet 3.
On plie l'ensemble en son milieu, ce qui est facilité par la ligne de pliage 7 et on applique sur les bords de l'emballage 9 les parties de l'élément 4 sur lesquelles l'adhésif 2 n'est pas revêtu par la portion 6 de la feuille siliconée, de façon que ces parties ne fassent pas saillie par rapport aux bords de l'emballage (voir Figure 4). The assembly is folded in the middle, which is facilitated by the fold line 7 and the parts of the element 4 on which the adhesive 2 is not coated with the portion 6 of the silicone sheet, so that these parts do not protrude with respect to the edges of the packaging (see Figure 4).
Dans ces conditions, l'emballage est fermé de façon inviolable et peut être accroché, par exemple à un présentoir, grace aux ouvertures 8a et 8b dont les bords sont appliqués l'un sur l'autre (Figure 5). Under these conditions, the packaging is closed in a tamper-proof manner and can be hung, for example on a display, thanks to the openings 8a and 8b, the edges of which are applied one on the other (Figure 5).
Pour ouvrir l'emballage, il suffit de découper suivant la ligne de pliage 7 l'élément 4 et la feuille 6 qui le recouvre. To open the packaging, simply cut along the fold line 7 the element 4 and the sheet 6 which covers it.
On forme ainsi deux volets 11 qui n'adherent pas l'un à l'autre car leur face interne est recouverte par la feuille siliconée 6 et qui raidissent les bords 9a de l'emballage 9 (Figure 6).Two flaps 11 are thus formed which do not adhere to each other because their internal face is covered by the silicone sheet 6 and which stiffen the edges 9a of the package 9 (Figure 6).
I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre au contraire, toutes les variantes. I1 goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants.
