Description

Domaine de l'inventionField of the invention

La présente invention concerne un sachet d'emballage préformé équipé d'un dispositif de fermeture pour recevoir des produits, notamment des produits alimentaires, et dont l'ouverture est bordée par une face munie d'une bande encollée, couverte par une bande de protection enlevée avant le collage avec l'autre face pour la fermeture du sachet.The present invention relates to a preformed packaging bag equipped with a closure device for receiving products, especially food products, and whose opening is bordered by a face provided with a glued strip, covered by a protective strip removed before gluing with the other side to close the bag.

Etat de la techniqueState of the art

On connaît déjà des sachets d'emballage préformés comme celui décrit ci-dessus. Ces sachets sont, en général, réalisés à partir de deux nappes de film ou d'un complexe, découpées suivant un format rectangulaire et soudées sur trois côtés, le quatrième côté constituant l'ouverture. Une face du sachet bordant l'ouverture est munie d'une bande encollée protégée par un ruban de papier siliconé de manière à protéger la bande encollée. Après avoir introduit le produit dans le sachet, on retire le ruban de protection pour permettre de coller l'autre face contre la bande ainsi encollée.Preformed packaging bags such as that described above are already known. These bags are, in general, made from two sheets of film or complex, cut in a rectangular format and welded on three sides, the fourth side constituting the opening. One side of the bag bordering the opening is provided with a glued strip protected by a ribbon of silicone paper so as to protect the glued strip. After having introduced the product into the bag, the protective tape is removed to allow the other face to be glued against the band thus bonded.

Ces sachets sont notamment utilisés dans le commerce alimentaire de détail, pour recevoir des produits frais, débités, tels que du poisson ou de la viande. Malheureusement, en introduisant les produits dans le sachet, il arrive que l'on souille la surface du sachet bordant l'ouverture et qui n'est pas encollée, c'est-à-dire protégée par la bande siliconée de sorte que cette surface mouillée ou salie collera mal ou difficilement avec la bande encollée pour la fermeture du sachet. Lorsque le sachet contient un produit non neutre tel que du poisson ou de fromage, il est souhaitable qu'il soit fermé d'une manière relativement hermétique pendant le transport et/ ou pendant le stockage au réfrigérateur.These bags are particularly used in the retail food trade, to receive fresh products, debit, such as fish or meat. Unfortunately, by introducing the products into the bag, it sometimes happens that the surface of the bag bordering the opening is defiled and that is not glued, that is to say protected by the silicone strip so that this surface wet or soiled will stick poorly or with difficulty with the tape glued for closing the bag. When the bag contains a non-neutral product such as fish or cheese, it is desirable that it be closed in a relatively tight manner during transport and / or during storage in the refrigerator.

Malheureusement, cette herméticité est rarement garantie à cause du mauvais collage du dispositif de fermeture dont une partie peut parfois être souillée comme indiqué.Unfortunately, this hermeticity is rarely guaranteed because of the bad gluing of the closure device, some of which can sometimes be soiled as indicated.

Ce sachet a également l'inconvénient de s'ouvrir relativement difficilement lorsqu'il est aplati car les deux faces bordant l'ouverture sont souvent appliquées l'un contre l'autre par la simple adhérence de la matière ; il est difficile d'ouvrir le sachet rapidement et simplement, surtout si l'utilisateur a les mains mouillées ou porte des gants comme cela est le cas pour les points de vente de détail de viandes, poissons, fromages.This bag also has the disadvantage of opening relatively difficult when flattened because the two sides bordering the opening are often applied against each other by the mere adhesion of the material; it is difficult to open the bag quickly and simply, especially if the user has wet hands or gloves as is the case for retail outlets of meat, fish, cheese.

Or, la facilité d'ouverture est un élément important pour la rapidité du service des clients.However, the ease of opening is an important element for the speed of customer service.

En outre, si l'ouverture est difficile à réaliser, le sachet peut être froissé ce qui ne donne pas une bonne image de marque surtout si le sachet est identifié par une marque ou une image publicitaire et en plus le contenu peut être abîméIn addition, if the opening is difficult to achieve, the bag can be wrinkled which does not give a good brand image especially if the bag is identified by a brand or an advertising image and in addition the content may be damaged

But de l'inventionPurpose of the invention

La présente invention a pour but de développer un sachet d'emballage préformé, équipé d'un dispositif de fermeture et qui puisse s'ouvrir simplement et rapidement et permette d'assurer une fermeture d'une bonne tenue garantissant l'étanchéité de la fermeture.The object of the present invention is to develop a preformed packaging bag, equipped with a closing device and which can be opened quickly and easily and makes it possible to ensure a good seal which guarantees the tightness of the closure. .

Exposé et avantages de l'inventionDescription and advantages of the invention

A cet effet, l'invention concerne un sachet du type défini ci-dessus caractérisé en ce que l'ouverture se prolonge d'une part, par une lèvre munie d'une bande adhésive occupant toute la longueur de l'ouverture et protégée par une bande amovible, avant collage et, d'autre part, par une autre lèvre repliée de fabrication, contre la face extérieure du sachet et destinée à être collée à la lèvre encollée pour fermer le sachet.For this purpose, the invention relates to a bag of the type defined above characterized in that the opening is extended on the one hand by a lip provided with an adhesive strip occupying the entire length of the opening and protected by a removable strip, before gluing and, on the other hand, by another folded manufacturing lip, against the outer face of the bag and intended to be glued to the glued lip to close the bag.

La lèvre ou le rabat ainsi formé par prépliage de fabrication est protégée par cette surface qui viendra ultérieurement se coller contre la bande encollée, car elle ne sera pas directement en contact avec les produits que l'on glisse dans le sachet, de sorte qu'elle ne risque pas d'être ainsi souillée et de mal adhérer à la bande encollée.The lip or the flap thus formed by pre-molding is protected by this surface which will subsequently stick against the glued strip, because it will not be in direct contact with the products that are slipped into the bag, so that it is not likely to be so soiled and to adhere badly to the glued tape.

Cette lèvre repliée sur le dessus du sachet aplati favorise également la prise du sachet d'une pile de sachets placés dans une boîte ou un distributeur équipant un comptoir ou, plus généralement, le point de vente.This lip folded over the top of the flattened bag also favors the bag of a bag of bags placed in a box or a dispenser equipping a counter or, more generally, the point of sale.

En outre, le repliement de la lèvre ne gêne pas l'application de la bande de colle sur toute la longueur de la lèvre, jusqu'au bord de celle-ci et jusqu'à la ligne de pliage. La bande encollée, s'étendant jusqu'aux deux bords du sachet, permet de bien sceller de façon étanche, l'ouverture après rabattement de la lèvre non encollée.In addition, the folding of the lip does not hinder the application of the adhesive strip over the entire length of the lip, to the edge thereof and up to the fold line. The glued strip, extending to the two edges of the bag, makes it possible to tightly seal the opening after folding of the unsized lip.

Pour favoriser l'enlèvement de la bande de protection, il est avantageux que l'un des coins ou, de préférence, les deux coins extérieurs de la lèvre encollée soient tronqués et que la bande de protection arrive dans cette zone tronquée tout en restant à l'intérieur du contour géométrique du sachet pour faciliter la préhension de cette bande encollée et son enlèvement après mise en place des produits dans le sachet pour être ensuite fermé.To promote the removal of the protective strip, it is advantageous that one of the corners or, preferably, the two outer corners of the glued lip are truncated and that the protective strip arrives in this truncated area while remaining at inside the geometric outline of the bag to facilitate the gripping of this glued strip and its removal after placing the products in the bag to be then closed.

La lèvre repliée rigidifie également le bord de l'ouverture du sachet et facilite ainsi l'introduction du produit : pour introduire le produit, on peut s'appuyer sur la lèvre encollée qui repose à plat sur le comptoir ou une tablette pendant qu'avec l'autre main et en se servant d'un doigt, on écarte le bord formé par le pli de la lèvre repliée, qui est ainsi relativement rigide dans la direction transversale et offre une bonne résistance pour être soulevé sans risquer que la lèvre repliée ne se rabatte automatiquement ou mécaniquement sur le produit et risque de se souiller. Le produit se glisse alors facilement dans le sachet sans que des éventuelles aspérités ou reliefs du produit qui pourraient s'accrocher ne déforment le bord de la lèvre, puisque ce bord est rabattu et que l'ouverture du sachet présente ainsi une double épaisseur au niveau du pli.The folded lip also stiffens the edge of the opening of the bag and thus facilitates the introduction of the product: to introduce the product, we can rely on the glued lip that lies flat on the counter or tablet while with the other hand and using a finger, the edge formed by the fold of the folded lip is spread apart, which is thus relatively rigid in the transverse direction and offers good resistance to be raised without risking that the folded lip does not folds automatically or mechanically onto the product and may become dirty. The product then slips easily into the bag without any asperities or projections of the product that could catch deform the edge of the lip, since this edge is folded and the opening of the bag thus has a double thickness at the level fold.

Description de modes de réalisation de l'inventionDescription of Embodiments of the Invention

Selon les figures 1, 2, 3, l'invention concerne un sachet S d'emballage, préformé, équipé d'un dispositif de fermeture DF. Ce sachet d'emballage S est destiné à recevoir des produits, notamment des produits alimentaires frais tels que de la viande, du poisson, du fromage, doit pouvoir être fermé d'une manière étanche, pour éviter que les odeurs dégagées par les produits ainsi emballés ne se propagent dans un panier, sac de courses ou dans le réfrigérateur lorsque le sachet y est provisoirement stocké avant consommation du produit.According to figures 1 , 2, 3 the invention relates to a pack S, preformed, equipped with a closing device DF. This packaging bag S is intended to receive products, especially fresh food products such as meat, fish, cheese, must be able to be closed in a sealed manner, to prevent the odors released by the products as well as packaged in a basket, shopping bag or in the refrigerator when the bag is temporarily stored there before consumption of the product.

Le sachet S selon l'exemple présenté a une forme rectangulaire. Il est composé de deux nappes N1, N2 d'un film simple ou composite, par exemple métallisé ; les nappes sont soudées sur trois côtés 1, 2, 3 et laissent le quatrième côté 4 ouvert. L'ouverture O est bordée par une première lèvre 5 située dans le prolongement de l'une des faces N1 du sachet S. Cette lèvre 5 occupe toute la largeur L de l'ouverture O et se présente sous la forme d'une bande. Cette première lèvre 5 porte une bande adhésive ou bande encollée 7, active 6 (figure 3), protégée par une bande siliconée 8 pour ne pas adhérer avant que l'on ne ferme le sachet S.The bag S according to the example shown has a rectangular shape. It is composed of two sheets N1, N2 of a single or composite film, for example metallized; the plies are welded on three sides 1, 2, 3 and leave the fourth side 4 open. The opening O is bordered by a first lip 5 located in the extension of one of the faces N1 of the bag S. This lip 5 occupies the entire width L of the opening O and is in the form of a band. This first lip 5 carries an adhesive strip or adhesive strip 7, active 6 ( figure 3 ), protected by a silicone band 8 to avoid adhering before the S-bag is closed.

Les deux coins 9, 10 de cette lèvre 5 sont tronqués mais la bande de protection 8 couvre la zone tronquée à l'intérieur du contour géométrique du sachet à plat, c'est-à-dire de la forme rectangulaire de ce sachet selon cet exemple. Ce contour n'est pas identifié par une référence.The two corners 9, 10 of this lip 5 are truncated, but the protective strip 8 covers the truncated area inside the geometric outline of the flat bag, that is to say the rectangular shape of this bag according to this example. This outline is not identified by a reference.

Les parties tronquées des coins 9, 10 permettent d'accéder plus facilement à un coin de la bande adhésive 8 pour l'enlever et permettre de fermer le sachet.The truncated portions of the corners 9, 10 make it easier to access a corner of the adhesive strip 8 to remove it and to close the bag.

L'autre lèvre ou seconde lèvre 6 destinée à coopérer avec la lèvre encollée 5 est repliée vers l'extérieur autour d'une ligne de pliage 11. Ce pliage est réalisé au moment de la fabrication du sachet S qui se présente comme indiqué à la figure 1. La face de la lèvre 6 qui sera ultérieurement fixée à la bande encollée est tournée vers le dessus.The other lip or second lip 6 intended to cooperate with the glued lip 5 is bent outwardly around a fold line 11. This folding is performed at the time of manufacture of the bag S which is as indicated in FIG. figure 1 . The face of the lip 6 which will subsequently be attached to the glued strip is turned towards the top.

Le sachet S porte sur l'une de ses faces ou ses deux faces différentes indications 12-16, marques, logos, modes d'emploi, etc.... schématisés par des rectangles.The bag S carries on one of its faces or two sides different indications 12-16, brands, logos, instructions, etc. ... schematized by rectangles.

Les figures 2 et 3 montrent d'une manière plus détaillée les moyens de l'invention.The Figures 2 and 3 show in more detail the means of the invention.

Ainsi, à la figure 2, la zone encollée 7 est couverte par la bande de palier siliconé 8, schématisé par des hachures croisées. La lèvre repliée 6 autour de sa ligne de pliage 11 est soulignée par des hachures transversales. Le coin 9, le cas échéant tronqué de la lèvre encollée 5, est schématisé par un contour en pointillés.So, at the figure 2 , the glued zone 7 is covered by the silicone bearing strip 8, schematized by crossed hatching. The folded lip 6 around its fold line 11 is underlined by transverse hatches. The corner 9, where appropriate truncated of the glued lip 5, is schematized by a dashed outline.

La figure 3 montre comment s'enlève la bande siliconée 8 protégeant la bande adhésive 7 de la lèvre encollée 5.The figure 3 shows how the silicone tape 8 protects the adhesive strip 7 from the glued lip 5.

Cette figure montre également que la bande encollée 7 arrive jusqu'à l'arrêt de la soudure du côté 1, arrêt de la soudure qui correspond à la ligne de pliage 11.This figure also shows that the glued strip 7 reaches the end of the welding of the side 1, stop of the weld which corresponds to the fold line 11.

La figure 4 montre schématiquement une pile de sachets S sortant de fabrication ou tels qu'ils sont à la disposition de l'utilisateur. Les sachets sont empilés tels qu'ils sortent de fabrication, avec la lèvre non encollée 6, repliée. L'ensemble de la pile est conditionné en paquets dans des cartons ou présentoirs pour être accessible, de préférence par le dessus.The figure 4 schematically shows a stack of bags S out of manufacture or as they are available to the user. The bags are stacked as they come out of production, with the unsized lip 6, folded. The entire stack is packaged in packs in cartons or displays to be accessible, preferably from above.

La figure 5 montre schématiquement la forme que présente le sachet S lorsque les deux lèvres 5, 6 sont écartées l'une de l'autre pour introduire un produit dans le sachet. Cette figure laisse clairement apparaître que l'on peut s'appuyer sur la lèvre encollée 5, en s'appuyant sur la bande de protection 8 et en écartant ou en soulevant l'autre lèvre 6 pour former une ouverture en losange. Au moment de l'introduction du produit, comme la lèvre non encollée 6 est repliée à l'extérieur et du fait même de la déformation telle qu'elle apparaît à la figure 5, la lèvre ne risque pas de se rabattre automatiquement vers l'avant, elle reste bien en dehors de toute zone de contact avec le produit que l'on introduit dans le sachet. La surface de cette lèvre 6 destinée à être reliée à la bande encollée 7 ne risque pas dans ces conditions d'être souillée par le contact avec le produit placé dans le sachet.The figure 5 schematically shows the shape of the bag S when the two lips 5, 6 are spaced from each other to introduce a product in the bag. This figure clearly shows that one can rely on the glued lip 5, relying on the protective strip 8 and by removing or lifting the other lip 6 to form a diamond-shaped opening. At the time of introduction of the product, as the unsized lip 6 is folded to the outside and the very fact of the deformation as it appears in the figure 5 , the lip is not likely to fall back automatically, it remains well outside any contact area with the product that is introduced into the bag. The surface of this lip 6 intended to be connected to the glued strip 7 is not in these conditions to be contaminated by contact with the product placed in the bag.

Après cette mise en place, il suffit d'enlever la bande de protection 8 de la lèvre encollée 5 et de rabattre l'autre lèvre 6, par exemple en passant simplement la main sur le dessus du sachet pour rabattre la seconde lèvre 6 en regard de la lèvre encollée 5, puis d'appuyer le long de la seconde lèvre 6 pour fermer le sachet de manière étanche. Comme la bande encollée 7 s'étend jusqu'aux deux côtés de la lèvre et jusqu'à la commissure des deux lèvres, à l'extrémité de la zone soudée de chacun des deux côtés du sachet s'arrêtant à la ligne de pliage, la fermeture sera quasiment étanche.After this installation, simply remove the protective strip 8 of the glued lip 5 and fold the other lip 6, for example simply by passing the hand on the top of the bag to fold the second lip 6 next to of the glued lip 5, then to press along the second lip 6 to close the bag tightly. As the glued strip 7 extends to both sides of the lip and to the commissure of the two lips, at the end of the welded zone of each of the two sides of the bag stopping at the fold line, the closure will be almost watertight.

La figure 6 montre le sachet fermé.The figure 6 shows the closed bag.

Le produit est bien emprisonné dans le sachet et évite de contaminer par les odeurs les autres produits transportés ou stockés en même temps que lui.The product is well trapped in the bag and avoids contaminating by smell other products transported or stored at the same time.
