Description

La présente invention concerne un emballage de type sachet qui peut être scellé après son emplissage d'un produit, ledit emballage pouvant être refermé après une première ouverture en sorte d'extraire plusieurs quantités du produit à intervalles de temps séparés et de préserver le reste du produit dans l'emballage refermé. Un tel emballage trouve par exemple son application dans les rayons de poissonnerie, de charcuterie ou de fromagerie, pour le conditionnement in situ d'aliments frais dans ledit emballage directement par le commerçant au moment où il sert ses clients.The present invention relates to a sachet-type package that can be sealed after it has been filled with a product, said package being closable after a first opening so as to extract several amounts of the product at separate time intervals and preserve the rest of the product. produced in the closed package. Such a package finds its application, for example, in the fish, deli or cheese department, for the in situ packaging of fresh food in said packaging directly by the merchant at the time he serves his customers.

Il est connu des emballages ou sachets qui comprennent un système de fermeture repositionnable en sorte de permettre la fermeture de l'emballage une fois empli de produit, puis son ouverture afin d'extraire une quantité du produit, et ensuite une nouvelle fermeture en repositionnant le système de fermeture afin de préserver le reste dudit produit contenu dans l'emballage. Ainsi, le produit peut être consommé en plusieurs fois. Ce type d'emballage présente pour inconvénient de permettre aux consommateurs frauduleux de se servir dans les rayons du magasin en libre-service, d'extraire une quantité de produit de l'emballage directement à l'intérieur du magasin, puis de repositionner convenablement le système de fermeture et de laisser ledit emballage entamé dans le rayon. Inversement, le consommateur frauduleux peut ajouter une quantité complémentaire de produit dans l'emballage après avoir été pesé et étiqueté avec le prix de vente par le vendeur, avant le passage en caisse ; au moment du passage en caisse, le caissier peut éventuellement ne pas s'apercevoir que l'emballage a déjà été ouvert.There are known packaging or sachets which comprise a repositionable closure system so as to allow the closure of the package once filled with product, then its opening to extract a quantity of the product, and then a new closure by repositioning the closure system to preserve the remainder of said product contained in the package. Thus, the product can be consumed in several times. This type of packaging has the disadvantage of allowing fraudulent consumers to use the shelves of the self-service store, to extract a quantity of product from the package directly inside the store, then to properly reposition the closing system and leave said package started in the radius. Conversely, the fraudulent consumer may add an additional quantity of product in the package after being weighed and labeled with the selling price by the seller, before the checkout; at the time of checkout, the cashier may not be able to see that the package has already been opened.

Certains emballages de l'art antérieur permettent de pallier cet inconvénient en proposant un emballage ou sachet qui présente une poche configurée pour rester fermée en permanence avant une première ouverture qui est apparente lorsque celle-ci est réalisée. Une fois la poche ouverte, celle-ci peut être refermée provisoirement au moyen d'une fermeture repositionnable. A ce titre, il est connu le modèle d'utilité espagnol publié sous le numéro ES1074604U et la demande internationale de brevet publiée sous le numéro Le document ES1074604U décrit un emballage qui comprend une feuille arrière, une feuille intermédiaire et une feuille avant. La feuille intermédiaire et la feuille avant sont scellées entre elles sur les côtés latéraux et sur le côté inférieur en sorte de former une poche. Un système de fermeture de type cordon de soudure est mis oeuvre entre la feuille intermédiaire et la feuille avant, sur le côté supérieur, pour fermer la poche en permanence avant une première ouverture. Des moyens de découpage sont agencés en-dessous de ce système de fermeture pour découper le côté supérieur des feuilles intermédiaire et avant scellées entre elles, de sorte à ouvrir la poche et à pouvoir accéder aux produits conditionnés à l'intérieur de celle-ci. La feuille arrière est assemblée avec la feuille intermédiaire sur sa partie inférieure située en-dessous des moyens de découpage, tandis que sa partie supérieure comprend sur sa face interne des moyens de fermeture adhésifs et repositionnables. Lorsque la poche est ouverte, le côté supérieur des feuilles intermédiaire et avant, soudées entre-elles, est détaché. Cela permet de rabattre le côté supérieur de la feuille arrière avec les moyens de fermeture adhésifs et repositionnables, sur la face externe de la feuille avant, pour fermer provisoirement l'emballage après sa première ouverture.Some packages of the prior art can overcome this disadvantage by providing a package or bag that has a pocket configured to remain permanently closed before a first opening that is apparent when it is performed. Once the pocket is open, it can be closed temporarily by means of a repositionable closure. As such, it is known the Spanish utility model published under the number ES1074604U and the international patent application published under the number The document ES1074604U describes a package that includes a backsheet, an intermediate sheet, and a front sheet. The intermediate sheet and the front sheet are sealed together on the lateral sides and on the lower side so as to form a pocket. A weld seam closure system is provided between the intermediate sheet and the front sheet, on the upper side, to close the bag permanently before a first opening. Cutting means are arranged below this closure system to cut the upper side of the intermediate sheets and before sealed between them, so as to open the bag and to access the packaged products inside thereof. The back sheet is assembled with the intermediate sheet on its lower part located below the cutting means, while its upper part comprises on its inner face adhesive closure means and repositionable. When the pocket is open, the upper side of the intermediate and front sheets, welded together, is detached. This allows to fold the upper side of the back sheet with the adhesive closure means and repositionable on the outer face of the front sheet, to temporarily close the package after its first opening.

A ce titre, l'emballage comprend des moyens de fermeture permanente de l'ouverture de poche, lesdits moyens de fermeture permanente étant configurés entre lesdites feuilles sur le côté supérieur de l'emballage, pour être mis en place et fermer la première ouverture une fois la poche emplie d'un produit. L'emplissage en produit de la poche et la mise en place des moyens de fermeture permanente sont réalisés par le commerçant ou le vendeur dans le magasin en fonction des produits commandés par le client, voire sont réalisés directement par le client qui se sert seul dans le magasin. Lesdites feuilles sont assujetties entre elles sur ledit côté supérieur, de préférence bord-à-bord, lors de la mise en place des moyens de fermeture permanente. En outre, les moyens de fermeture permanente restent en position en permanence sur l'emballage une fois mis en place par le commerçant, c'est-à-dire qu'ils ne sont pas détachés ou découpés pour ouvrir la poche, et la seconde feuille comprend des moyens d'ouverture facile configurés pour créer manuellement une seconde ouverture sur cette seconde feuille, décalée en-dessous des moyens de fermeture permanente, en sorte d'ouvrir ladite poche et d'accéder aux produits. La partie supérieure de l'emballage, constituée de la partie supérieure de la première feuille et de la partie supérieure de la seconde feuille assemblées en permanence entre elles grâce aux moyens de fermeture permanente, forme un rabat configuré pour être rabattu sur la face externe de la seconde feuille en recouvrant ladite seconde ouverture, ce qui permet de refermer la poche. Par ailleurs, l'emballage comprend des moyens de fermeture repositionnable qui sont configurés sur ladite face externe pour maintenir provisoirement le rabat en position de fermeture de la seconde ouverture. Ainsi, la conception de l'emballage permet avantageusement de limiter le nombre de feuilles, en comparaison de l'emballage décrit dans le document ES1074604U , et supprime l'ajout d'un rabat complémentaire qui s'étend de l'une des feuilles, en comparaison de l'emballage décrit dans le document WO9964308A1 On réduit ainsi la quantité de matière première utilisée pour la fabrication de l'emballage selon l'invention.For this purpose, the invention relates to a package comprising a first sheet and a second sheet. The two sheets are preferably of identical dimensions and they are sealed together on the lateral sides and on the lower side of the package, which allows to form a pocket with a top opening a first opening, before a first use of the package where said bag will be closed after the introduction of a product, for example food. As such, the package comprises means for permanently closing the pocket opening, said permanent closure means being configured between said sheets on the upper side of the package, to be put in place and close the first opening a pocket filled with a product. The filling of the bag with the product and the establishment of the means of permanent closure are carried out by the merchant or the seller in the store according to the products ordered by the customer, or are made directly by the customer who uses himself in the shop. Said sheets are secured to each other on said upper side, preferably edge-to-edge, during the establishment of the permanent closure means. In addition, the permanent closure means remain in position permanently on the package once set up by the merchant, that is to say, they are not detached or cut to open the pocket, and the second sheet comprises easy opening means configured to manually create a second opening on this second sheet, shifted below the permanent closure means, so as to open said pocket and access the products. The upper part of the package, consisting of the upper part of the first sheet and the upper part of the second sheet permanently assembled together by means of permanent closure means, forms a flap configured to be folded on the outer face of the second sheet covering said second opening, which allows to close the bag. Furthermore, the packaging comprises repositionable closing means which are configured on said outer face to temporarily hold the flap in the closed position of the second opening. Thus, the design of the package advantageously makes it possible to limit the number of sheets, in particular comparison of the packaging described in the document ES1074604U , and removes the addition of a complementary flap that extends from one of the sheets, in comparison to the package described in the document WO9964308A1 This reduces the amount of raw material used for the manufacture of the package according to the invention.

Selon une réalisation de l'emballage objet de l'invention, les feuilles sont imperméables. En outre, les moyens de fermeture permanente sont configurés pour assurer une étanchéité de fermeture du côté supérieur avec les côtés latéraux, lors de leur mise en place. On pourrait toutefois prévoir des feuilles poreuses et des moyens de fermeture qui n'assurent pas une étanchéité totale entre le côté supérieur et les côtés latéraux de l'emballage, sans sortir du cadre de l'invention ; cela serait par exemple envisageable pour un emballage pour des produits de quincaillerie ou pour des produits chauds, afin de limiter la condensation, voire pour d'autres produits.According to one embodiment of the packaging object of the invention, the sheets are impermeable. In addition, the permanent closure means are configured to ensure a closure seal of the upper side with the lateral sides, when they are put in place. However, there could be provided porous sheets and closure means that do not provide a complete seal between the upper side and the lateral sides of the package, without departing from the scope of the invention; this would be feasible, for example, for packaging for hardware products or for hot products, in order to limit condensation or even for other products.

De préférence, selon cette réalisation de l'emballage, les deux feuilles sont scellées entre elles sur les côtés latéraux au moyen d'au moins un cordons de scellage dont les bords supérieurs sont distants du bord supérieur de l'emballage, les moyens de fermeture permanente comprenant une première bande adhésive qui est agencée sur une face interne de l'une des feuilles et qui s'étend latéralement jusqu'au bords latéraux de la face interne, deux apports complémentaires d'adhésif agencés sur la face interne en joignant les bords supérieurs du cordon de scellage aux extrémités latérales de ladite bande adhésive, et une première bande de protection amovible qui s'étend latéralement entre les faces internes des feuilles et qui recouvre la bande adhésive et les deux apports complémentaires d'adhésif. Ce type d'emballage est configuré pour permettre une première fermeture de la poche in situ par le commerçant, après l'emplissage de la poche en produits, dans les rayons de produits frais tels que les rayons poissonnerie, fromagerie, boucherie et charcuterie.Preferably, according to this embodiment of the package, the two sheets are sealed together on the lateral sides by means of at least one sealing cords whose upper edges are spaced from the upper edge of the package, the closure means permanent assembly comprising a first adhesive strip which is arranged on an inner face of one of the sheets and which extends laterally to the lateral edges of the inner face, two complementary adhesive additions arranged on the inner face by joining the edges upper of the sealing bead at the lateral ends of said adhesive strip, and a first removable protective strip which extends laterally between the inner faces of the sheets and which covers the adhesive strip and the two complementary additions of adhesive. This type of packaging is configured to allow a first closure of the bag in situ by the trader, after filling the product bag, in the shelves of fresh products such as fish, dairy, meat and meat.

Selon cette réalisation préférentielle de l'emballage, des premiers moyens de préhension sont configurés pour saisir la première bande de protection et faciliter son retrait de la première bande adhésive. Ainsi, on facilite la réalisation de la première fermeture de la poche après son emplissage en produits.According to this preferred embodiment of the package, first gripping means are configured to grip the first protective strip and facilitate its removal from the first adhesive strip. Thus, it facilitates the realization of the first closure of the bag after filling into products.

Selon l'emballage objet de la présente invention, les moyens de fermeture repositionnable sont agencés en-dessous des moyens d'ouverture facile. Cette disposition présente pour avantage de canaliser l'ouverture de la poche entre les moyens de fermeture permanente et les moyens de fermeture repositionnable, en sorte d'éviter que l'ouverture ne se propage sur la seconde feuille. On pourrait toutefois envisager d'agencer ces moyens de fermeture repositionnable au-dessus des moyens d'ouverture facile, c'est-à-dire sur la partie formant le rabat, sans sortir du cadre de la présente invention.According to the packaging object of the present invention, the repositionable closing means are arranged below the easy opening means. This provision presents for advantage of channeling the opening of the pocket between the permanent closure means and the repositionable closing means, so as to prevent the opening from spreading on the second sheet. However, one could consider arranging these repositionable closure means above the easy opening means, that is to say on the flap portion, without departing from the scope of the present invention.

Selon une première réalisation des moyens de fermeture facile de l'emballage objet de l'invention, ceux-ci sont constitués d'une ligne de prédécoupes qui s'étend latéralement sur la face externe.According to a first embodiment of the easy closure means of the packaging object of the invention, these consist of a pre-cut line which extends laterally on the outer face.

Selon cette première réalisation, des seconds moyens de préhension sont agencés sur la face externe de la seconde feuille, sur au moins un des côtés de la ligne de prédécoupes. Cela présente pour avantage de faciliter la saisie avec les doigts de la seconde feuille, de chaque côté de la ligne de prédécoupes, pour tirer dans deux directions opposées et arracher la seconde feuille selon cette ligne de prédécoupes. Cela est d'autant plus avantageux lorsque le produit contenu dans la poche est plat et humide, par exemple des tranches de jambon, et que les faces internes des deux feuilles collent sur ce produit, ce qui empêcherait de saisir facilement la seconde feuille en l'absence desdits seconds moyens de préhension. Bien entendu, des variantes de seconds moyens de préhension sont envisageables sans sortir du cadre de l'invention.According to this first embodiment, second gripping means are arranged on the outer face of the second sheet, on at least one side of the pre-cut line. This has the advantage of facilitating the gripping with the fingers of the second sheet, on each side of the pre-cut line, to fire in two opposite directions and tear the second sheet along this line of pre-cut. This is all the more advantageous when the product contained in the bag is flat and wet, for example slices of ham, and the internal faces of the two sheets stick on this product, which would prevent easy grasping the second sheet in the same way. absence of said second gripping means. Of course, variants of second gripping means are possible without departing from the scope of the invention.

Selon une seconde réalisation des moyens d'ouverture facile sur l'emballage objet de l'invention, ceux-ci comprennent deux lignes de prédécoupes qui s'étendent latéralement avec un écartement entre elles, en sorte de définir une bande prédécoupée. En outre, une bande adhésive revêt ladite bande prédécoupée, le coefficient d'adhérence de la bande adhésive étant supérieure au coefficient d'arrachement des lignes de prédécoupes, des moyens de préhension étant configurés pour saisir ladite bande adhésive. Ainsi, en tirant sur la bande adhésive, la bande prédécoupée se détache de la seconde feuille en sorte d'ouvrir la poche. Cette conception peut s'avérer avantageuse pour disposer d'une ouverture plus grande en sorte de faciliter l'accès au produit contenu dans la poche et son retrait de ladite poche.According to a second embodiment of the means of easy opening on the packaging object of the invention, they comprise two lines of pre-cuts which extend laterally with a spacing between them, so as to define a pre-cut strip. In addition, an adhesive tape covers said precut tape, the adhesion coefficient of the adhesive tape being greater than the tearing coefficient of the precut lines, gripping means being configured to grip said adhesive tape. Thus, by pulling on the adhesive strip, the pre-cut strip is detached from the second sheet so as to open the pocket. This design may be advantageous for having a larger opening so as to facilitate access to the product contained in the pocket and its withdrawal from said pocket.

Selon une réalisation de l'emballage objet de l'invention, les moyens de fermeture repositionnable sont constitués d'une seconde bande adhésive s'étendant latéralement, directement ou indirectement, sur la face externe de la seconde feuille, et d'une seconde bande de protection amovible revêtant ladite seconde bande adhésive avant la mise en place desdits moyens de fermeture repositionnable.According to one embodiment of the packaging object of the invention, the repositionable closing means consist of a second adhesive strip extending laterally, directly or indirectly, on the outer face of the second sheet, and a second removable protective strip coating said second adhesive strip before the introduction of said repositionable closure means.

Selon une réalisation de l'emballage objet de l'invention, la première feuille est constituée d'un papier polyéthylène et la seconde feuille est constituée d'un film transparent. Bien entendu des variantes sont envisageables ; on pourrait par exemple envisager deux feuilles constituées chacune d'un papier polyéthylène ou d'un film transparent.According to one embodiment of the packaging object of the invention, the first sheet is made of a polyethylene paper and the second sheet is made of a transparent film. Of course, variants are conceivable; one could for example consider two sheets each consisting of a polyethylene paper or a transparent film.

Dans la suite de la description, les mêmes références sont utilisées pour définir les mêmes caractéristiques ou leurs équivalentes, selon les différentes variantes de réalisation.In the rest of the description, the same references are used to define the same characteristics or their equivalents, according to the different embodiments.

Sur la figure 1, l'emballage 1 est illustré avant son emplissage de produits et sa fermeture. L'emballage 1 comprend une première feuille 2 et une seconde feuille 3, de préférence de dimensions identiques. La première feuille 2 est de préférence réalisée dans un matériau opaque et assurant une isolation thermique, par exemple un papier polyéthylène. La seconde feuille 3 est de préférence réalisée dans un film transparent qui permet une visualisation des produits contenus dans l'emballage. Sur les figures 1 à 3, la première feuille 2 et la seconde feuille 3 sont scellées entre elles sur les côtés latéraux 1a, 1b et sur le côté inférieur 1c de l'emballage au moyen d'un cordon de soudure 4, ce qui permet la formation d'une poche 5, que l'on distingue plus en détail sur la figure 4. On peut envisager de réaliser les feuilles 2, 3 dans d'autres matériaux sans sortir du cadre de l'invention ; par exemple, les deux feuilles 2, 3 peuvent être en papier polyéthylène ou dans un film transparent.On the figure 1 , the package 1 is illustrated before its filling of products and its closure. The package 1 comprises a first sheet 2 and a second sheet 3, preferably of identical dimensions. The first sheet 2 is preferably made of an opaque material and providing thermal insulation, for example a polyethylene paper. The second sheet 3 is preferably made of a transparent film which allows visualization of the products contained in the package. On the Figures 1 to 3 , the first sheet 2 and the second sheet 3 are sealed together on the lateral sides 1a, 1b and on the lower side 1c of the package by means of a weld bead 4, which allows the formation of a pocket 5, which the 'we distinguish more in detail on the figure 4 . It is conceivable to make the sheets 2, 3 in other materials without departing from the scope of the invention; for example, the two sheets 2, 3 may be polyethylene paper or in a transparent film.

Lorsque les deux feuilles 2, 3 sont réalisées dans un même matériau, la poche 5 peut être réalisée au moyen d'une seule feuille constituant lesdites deux feuilles 2, 3, ladite seule feuille étant pliée en deux au niveau du côté inférieur 1c de l'emballage 1, et deux cordons de soudure 4a, 4b sont réalisés sur les côtés latéraux 1a, 1b dudit emballage 1, tel que cela est illustré en figure 5.When the two sheets 2, 3 are made of the same material, the pocket 5 can be made by means of a single sheet constituting said two sheets 2, 3, said single sheet being folded in two at the lower side 1c of the 1, and two weld seams 4a, 4b are made on the lateral sides 1a, 1b of said package 1, as illustrated in FIG. figure 5 .

La poche 5 présente une première ouverture 6 définie sur le côté supérieur 1d de l'emballage 1, tel qu'illustré en figure 1, cette ouverture 6 permettant l'introduction de produits dans la poche 5. Une fois les produits 7a, 7b, 7c, 7d introduits dans la poche 5, des moyens de fermeture permanente 8 sont mis en place, tel que l'illustrent les figures 1 et 2.The pocket 5 has a first opening 6 defined on the upper side 1d of the package 1, as illustrated in FIG. figure 1 , this opening 6 allowing the introduction of products into the pocket 5. Once the products 7a, 7b, 7c, 7d introduced into the pocket 5, permanent closure means 8 are put in place, as illustrated by the figures 1 and 2 .

De préférence, ces moyens de fermeture permanente 8 sont configurés pour assurer une étanchéité totale de l'emballage 1 une fois mis en place. Les moyens de fermeture permanente 8 comprennent une première bande adhésive 9 qui est agencée sur la face interne 2a de la première feuille 2, latéralement entre ses deux bords latéraux 11a, 11b. Cette première bande adhésive 9 est décalée par rapport aux deux extrémités latérales supérieures 10a, 10b du cordon de soudure 4 dans le cas des figures 1 à 3, voire des cordons de soudure 4a, 4b dans le cas de la figure 5. En outre, deux apports complémentaires de substance adhésive 12, 13 sont agencés respectivement sur la face interne 2a de la première feuille 2, au niveau de ses bords latéraux 11a, 11b, et couvrent les extrémités latérales supérieurs 10a, 10b du cordon 4 et deux portions latérales 14a, 14b du bord inférieur 9a de la première bande adhésive 9. Le bord supérieur 9b de cette première bande adhésive 9 est de préférence attenant au bord supérieur 15 de la face interne 2a de la première feuille 2. En outre, une première bande de protection 16 recouvre les deux apports complémentaires de substance adhésive 12, 13 et la première bande adhésive 9, ce qui empêche provisoirement le scellage permanent par collage de la face interne 3a de la seconde feuille 3 avec la face interne 2a de la première feuille 2, sur le côté supérieure 1d de l'emballage 1, pour empêcher d'accéder à la poche 5 par la première ouverture 6. Cette bande de protection 16 dépasse latéralement des bords latéraux 11a, 11b, ce qui facilite sa préhension au moment de procéder à son retrait. Une fois les produits 7a, 7b, 7c, 7d insérés dans la poche 5 par l'ouverture 6, la première bande de protection 16 est retirée, ce qui permet le collage permanent entre lesdites deux faces internes 2a, 3a, les deux apports complémentaires 12, 13 garantissant une continuité du scellage permanent entre les extrémités 10a, 10b du cordon 4 et la première bande adhésive 9. La mise en place de ces moyens de fermeture permanente 8 empêche toute extraction des produits 7a, 7b, 7c, 7d hors de la poche 5, par la première ouverture 6 qui est définitivement fermée.Preferably, these permanent closure means 8 are configured to ensure complete sealing of the package 1 once in place. The permanent closure means 8 comprise a first adhesive strip 9 which is arranged on the inner face 2a of the first sheet 2, laterally between its two side edges 11a, 11b. This first adhesive strip 9 is offset with respect to the two upper lateral ends 10a, 10b of the weld seam 4 in the case of Figures 1 to 3 , or weld seams 4a, 4b in the case of the figure 5 . In addition, two complementary additions of adhesive substance 12, 13 are respectively arranged on the inner face 2a of the first sheet 2, at its lateral edges 11a, 11b, and cover the upper lateral ends 10a, 10b of the cord 4 and two lateral portions 14a, 14b of the lower edge 9a of the first adhesive strip 9. The upper edge 9b of this first adhesive strip 9 is preferably adjoining the upper edge 15 of the inner face 2a of the first sheet 2. In addition, a first protective strip 16 covers the two complementary additions of adhesive substance 12, 13 and the first adhesive strip 9, which temporarily prevents permanent sealing by bonding the inner face 3a of the second sheet 3 with the inner face 2a of the first sheet 2, on the upper side 1d of the package 1, to prevent access to the pocket 5 by the first opening 6. This protective band 16 laterally exceeds the side edges 11a, 11b, which facilitates its grip when removing it. Once the products 7a, 7b, 7c, 7d inserted in the pocket 5 through the opening 6, the first protective strip 16 is removed, which allows the permanent bonding between said two inner faces 2a, 3a, the two complementary contributions 12, 13 guaranteeing continuity of permanent sealing between the ends 10a, 10b of the cord 4 and the first adhesive strip 9. The establishment of these permanent closure means 8 prevents any extraction of the products 7a, 7b, 7c, 7d out of the pocket 5, by the first opening 6 which is permanently closed.

L'homme du métier pourra également se reporter à la demande de brevet FR2921049A1 , déposée par la demanderesse, qui décrit en détail plusieurs variantes de réalisation de ces moyens de fermeture permanente 8 assurant une étanchéité, pour les modes de réalisation à deux feuilles sans intercalaire. Ces diverses variantes de réalisation décrites dans la demande de brevet FR2921049A1 sont donc envisageables dans le cadre de la présente invention.The skilled person may also refer to the request for FR2921049A1 , filed by the applicant, which describes in detail several variants of these permanent sealing means 8 ensuring a seal, for the two-sheet embodiments without spacer. These various embodiments described in the application for FR2921049A1 are therefore conceivable in the context of the present invention.

Bien entendu, les feuilles 2, 3 sont imperméables en sorte d'assurer une étanchéité totale de l'emballage 1 après sa première fermeture grâce aux moyens de fermeture permanente 8. On pourrait toutefois mettre en oeuvre des variantes de moyens de fermeture permanente 8, ne prévoyant pas de fermeture étanche, en particulier lorsque les produits conditionnés ne nécessitent pas une telle étanchéité.Of course, the sheets 2, 3 are impermeable so as to ensure complete sealing of the package 1 after its first closure by the permanent closure means 8. However, it would be possible to implement variants of permanent closure means 8, not providing tight closure, especially when the packaged products do not require such sealing.

Tel qu'illustré sur les figures 1 à 3, l'emballage 1 comprend des moyens d'ouverture facile 17 qui sont agencés sur la seconde feuille 3. Ces moyens d'ouverture facile 17 comprennent une ligne de prédécoupes 18 qui s'étend latéralement jusqu'à proximité des côtés latéraux 21a, 21b du cordon4, voire des deux cordons 4a, 4b dans le cas de la figure 5. Cette ligne de prédécoupes 18 permet de déchirer la seconde feuille 3 en sorte de laisser apparaître une seconde ouverture 19, illustrée en figure 3, qui permet l'extraction d'une partie des produits 7a, 7b, 7c, 7d contenus dans la poche 5. Deux languettes 20, 21 sont agencées sur la face externe 3b de la seconde feuille 3, respectivement de chaque côté de la ligne de prédécoupes 18, et facilitent le déchirement de la feuille 3 selon cette ligne de prédécoupes 18 en tirant dans deux directions plus ou moins opposées sur ces languettes 20, 21. On pourrait toutefois prévoir une seule des deux languettes 20, 21, ce qui faciliterait également le déchirement de la feuille 3 selon la ligne de prédécoupes 18 en tirant cette seule languette 20 ou 21 dans un sens et en maintenant l'autre côté de l'emballage 1.As illustrated on Figures 1 to 3 , the package 1 comprises easy opening means 17 which are arranged on the second sheet 3. These easy opening means 17 comprise a pre-cut line 18 which extends laterally to near the lateral sides 21a, 21b cord 4, or both cords 4a, 4b in the case of the figure 5 . This pre-cut line 18 makes it possible to tear the second sheet 3 so as to reveal a second opening 19, illustrated in FIG. figure 3 , which allows the extraction of part of the products 7a, 7b, 7c, 7d contained in the pocket 5. Two tongues 20, 21 are arranged on the outer face 3b of the second sheet 3, respectively on each side of the line precuts 18, and facilitate the tearing of the sheet 3 along this line of precuts 18 by pulling in two more or less opposite directions on these tabs 20, 21. On however, could provide only one of the two tabs 20, 21, which would also facilitate the tearing of the sheet 3 according to the precut line 18 by pulling this single tab 20 or 21 in one direction and maintaining the other side of the package 1.

On peut envisager des variantes de mises en oeuvre de moyens d'ouverture facile 17 sur la seconde feuille 3. Par exemple, sur la figure 4, ces moyens d'ouverture facile 17 comprennent deux lignes de prédécoupes 22a, 22b qui définissent une bande prédécoupée 23. Cette bande prédécoupée 23 s'étend latéralement jusqu'à proximité des côtés latéraux 21a, 21b du cordon 4. Une bande adhésive 24 recouvre cette bande prédécoupée 23 sur la face externe 3b de la seconde feuille 3. Cette bande adhésive 24 dépasse des bords latéraux 25a, 25b de la face externe 3a en sorte de faciliter sa préhension au moment de son retrait. La bande adhésive 24 comprend un coefficient d'adhérence supérieur à la force d'arrachement des lignes de prédécoupes 22a, 22b, ce qui permet lors du retrait de la bande adhésive 24, d'arracher la bande prédécoupée 23 qui se détache de la seconde feuille 3 et reste collée à la bande adhésive 23, en laissant apparaître la seconde ouverture 19.Variations of implementations of easy opening means 17 can be envisaged on the second sheet 3. For example, on the figure 4 these easy opening means 17 comprise two pre-cut lines 22a, 22b which define a pre-cut strip 23. This pre-cut strip 23 extends laterally to near the lateral sides 21a, 21b of the bead 4. An adhesive strip 24 covers this pre-cut strip 23 on the outer face 3b of the second sheet 3. This adhesive strip 24 protrudes from the lateral edges 25a, 25b of the outer face 3a so as to facilitate its gripping at the moment of its withdrawal. The adhesive strip 24 comprises a coefficient of adhesion greater than the tearing force of the pre-cut lines 22a, 22b, which makes it possible, during the removal of the adhesive strip 24, to tear off the pre-cut strip 23 which is detached from the second sheet 3 and remains glued to the adhesive strip 23, leaving the second opening 19 visible.

Sur les figures 1 à 4, l'emballage 1 comprend des moyens de fermeture repositionnable 26 qui sont agencés sur la face externe 3b de la seconde feuille 3, en-dessous des moyens d'ouverture facile 17. On pourrait toutefois prévoir leur agencement au-dessus desdits moyens d'ouverture facile 17. Ces moyens de fermeture repositionnable 26 comprennent une seconde bande adhésive 27 qui s'étend latéralement jusqu'aux bords latéraux 25a, 25b de la seconde feuille 3 sur laquelle ladite seconde bande adhésive 27 est agencée. Avant leur utilisation, ces moyens de fermeture repositionnable 26 comprennent une seconde bande de protection 28 qui revêt la seconde bande adhésive 27 en sorte de protéger l'emballage contre le collage intempestif d'éléments externes sur la face externe 3b de la seconde feuille 3. Cette seconde bande de protection 28 peut dépasser légèrement des bords latéraux 25a, 25b en sorte de faciliter sa préhension au moment de son retrait.On the Figures 1 to 4 , the package 1 comprises repositionable closing means 26 which are arranged on the outer face 3b of the second sheet 3, below the easy opening means 17. However, their arrangement could be provided above said means for These repositionable closure means 26 comprise a second adhesive strip 27 which extends laterally to the side edges 25a, 25b of the second sheet 3 on which said second adhesive strip 27 is arranged. Prior to their use, these repositionable closing means 26 comprise a second protective strip 28 which covers the second adhesive strip 27 so as to protect the package against inadvertent bonding of external elements on the outer face 3b of the second sheet 3. This second protective band 28 may slightly exceed lateral edges 25a, 25b so as to facilitate its grip at the time of its removal.

Lorsque la première ouverture de la poche 5 est réalisée grâce aux moyens d'ouverture facile 17, le consommateur peut extraire une partie seulement des produits 7a, 7b, 7c, 7d, comme le montrent les figures 2 et 3, au travers de la seconde ouverture 19. Le consommateur peut ensuite rabattre la partie supérieure 29 de l'emballage 1 formée de la partie supérieure de la première feuille 2 et de la partie supérieure de la seconde feuille 3 maintenues scellées entre elles par les moyens de fermeture permanente 8, ladite partie supérieure 29 de l'emballage 1 formant un rabat de fermeture de la seconde ouverture 19, comme l'illustre la figure 3. Cette partie supérieure 29 formant un rabat est maintenue en position rabattue sur la face externe 3b de la seconde feuille 3 grâce à la seconde bande adhésive 27. Le coefficient d'adhérence de la seconde bande adhésive 27 est choisi de telle sorte à permettre le décollement dudit rabat pour accéder à la seconde ouverture 19 et extraire une autre quantité de produit 7c, 7d, puis le recollage du rabat sur la face externe 3b.When the first opening of the pocket 5 is achieved by the easy opening means 17, the consumer can extract only part of the products 7a, 7b, 7c, 7d, as shown by the figures 2 and 3 through the second opening 19. The consumer can then fold down the upper part 29 of the package 1 formed of the upper part of the first sheet 2 and the upper part of the second sheet 3 held together by the permanent closure means 8, said upper portion 29 of the package 1 forming a closure flap of the second opening 19, as illustrated by FIG. figure 3 . This upper portion 29 forming a flap is held in the folded position on the outer face 3b of the second sheet 3 by means of the second adhesive strip 27. The adhesion coefficient of the second adhesive strip 27 is chosen so as to allow delamination said flap to access the second opening 19 and extract another quantity of product 7c, 7d, then the flap of the flap on the outer face 3b.

Sur la figure 6, les moyens d'ouverture facile 17 comprennent une ligne de prédécoupes 18 qui s'étend latéralement jusqu'à proximité des côtés latéraux 21a, 21b du cordon 4, comme dans le cas des figures 1 à 3, voire des deux cordons 4a, 4b, comme dans le cas de la figure 5. Une seule languette 20 est agencée en-dessous de la ligne de prédécoupes 18, cette languette 20 ayant la forme d'une bande qui s'étend latéralement sur la face externe 3b de la seconde feuille 3. Le bord longitudinal proximal 20a de la languette 20 est assemblé, par exemple par un cordon de soudure 30, à proximité de la ligne de prédécoupe 18. En outre, les moyens de fermeture repositionnable 26 sont agencés directement sur cette languette 20. La seconde bande adhésive 27 est disposée sur la languette 20 et est revêtue de la seconde bande de protection 28. On remarque sur la figure 6 que le bord longitudinal distal 28a de la seconde bande de protection 28 dépasse légèrement du bord longitudinal distal 20b de la languette 20, et que la longueur de la seconde bande de protection 28 est légèrement inférieure à celle de la languette 20, ce qui facilite la préhension de la seconde bande de protection 28 avec une main et le maintien de la languette 20 avec l'autre main, en sorte de retirer facilement ladite seconde bande de protection 28 et de libérer la seconde bande adhésive 27.On the figure 6 , the easy opening means 17 comprise a pre-cut line 18 which extends laterally to near the lateral sides 21a, 21b of the cord 4, as in the case of Figures 1 to 3 , even of the two cords 4a, 4b, as in the case of the figure 5 . A single tongue 20 is arranged below the pre-cut line 18, this tongue 20 having the shape of a band which extends laterally on the outer face 3b of the second sheet 3. The proximal longitudinal edge 20a of the tongue 20 is assembled, for example by a weld seam 30, close to the precut line 18. In addition, the repositionable closing means 26 are arranged directly on the tongue 20. The second adhesive strip 27 is disposed on the tongue 20 and is coated with the second protective strip 28. Note on the figure 6 that the distal longitudinal edge 28a of the second protection band 28 protrudes slightly from the distal longitudinal edge 20b of the tongue 20, and that the length of the second protective band 28 is slightly less than that of the tongue 20, which facilitates the gripping the second protective band 28 with one hand and holding the tab 20 with the other hand, so as to easily remove said second band 28 and release the second band 27.

D'autres variantes de mise en oeuvre sont envisageables sans sortir du cadre de l'invention, notamment en ce qui concerne les moyens de préhension de la première bande de protection 16 des moyens de fermeture permanente 8, en ce qui concerne les moyens de préhension de la seconde bande de protection 28 des moyens de fermeture repositionnable 26, et en ce qui concerne les moyens de préhension de la bande adhésive 24 de la seconde variante des moyens d'ouverture facile 17, illustrée en figure 4. On peut également prévoir des variantes de moyens de fermeture permanente 8, de moyens de fermeture repositionnable 26 et de moyens d'ouverture facile 17.Other alternative embodiments are conceivable without departing from the scope of the invention, in particular as regards the gripping means of the first protective strip 16 of the permanent closure means 8, with regard to the gripping means of the second protective strip 28 of the repositionable closing means 26, and with regard to the means for gripping the adhesive strip 24 of the second variant of the easy opening means 17, illustrated in FIG. figure 4 . We can also foresee variants of permanent closure means 8, repositionable closing means 26 and easy opening means 17.

D'autres caractéristiques sont également envisageables, comme la mise en oeuvre de moyens de pliage facilitant le pliage de la partie supérieure 29 de l'emballage 1 formant le rabat, selon une ligne de pliage définie et garantissant l'obturation convenable de la seconde ouverture 19 lors de la mise en place dudit rabat.Other features are also conceivable, such as the implementation of folding means facilitating the folding of the upper portion 29 of the package 1 forming the flap, according to a defined fold line and ensuring proper closure of the second opening 19 during the establishment of said flap.
