Abstract
Description
La présente invention concerne un dispositif d'ouverture/fermeture d'un emballage hermétique, notamment destiné à la conservation de produits agroalimentaires.The present invention relates to a device for opening / closing a hermetic packaging, in particular for preserving agri-food products.
Toutefois, bien que plus particulièrement prévue pour des emballages hermétiques destinés à la conservation de produits agroalimentaires, elle pourra également être utilisée pour l'emballage de tout autre type de produit.However, although more particularly intended for hermetic packaging intended for the preservation of agri-food products, it may also be used for the packaging of any other type of product.
On connaît des applications dans lesquels l'ouverture et la fermeture d'un emballage requièrent des précautions particulières visant notamment à éviter le contact entre le contenu ou le milieu intérieur de l'emballage et le milieu ambiant. ,Applications are known in which the opening and closing of a package require special precautions aimed in particular to prevent contact between the contents or the inner environment of the packaging and the surrounding environment. ,
Parmi ces applications, citons l'ouverture et la fermeture d'un emballage hermétique destiné à la conservation de produits agroalimentaires après leur traitement thermique. Dans cette première application, on sait qu'après un traitement thermique, certains produits alimentaires rejettent un jus de cuisson ou exsudat qui doit être retiré de l'emballage avant la commercialisation du produit. On sait également qu'il peut être utile voire indispensable de vérifier pendant ou après le traitement thermique certaines données comme la température du produit contenu dans l'emballage.These applications include the opening and closing of hermetic packaging for the preservation of food products after their heat treatment. In this first application, it is known that after a heat treatment, certain food products reject a cooking juice or exudate that must be removed from the packaging before marketing the product. It is also known that it may be useful or even essential to check during or after the heat treatment certain data such as the temperature of the product contained in the package.
Pour ces deux raisons précitées, et également pour d'autres raisons comme l'injection éventuelle de produits additionnels dans l'emballage, il est nécessaire de pouvoir accéder aux produits contenus dans l'emballage.For these two reasons, and also for other reasons such as the possible injection of additional products into the package, it is necessary to be able to access the products contained in the package.
Cela étant, compte tenu de la nature des produits, il n'est pas possible pour des raisons sanitaires de mettre en contact le milieu intérieur de l'emballage et le milieu ambiant lors de l'ouverture puis de rendre à nouveau hermétique l'emballage lors de la fermeture.However, given the nature of the products, it is not possible for sanitary reasons to put in contact the inner environment of the packaging and the surrounding environment during the opening and then make the packaging hermetic again. when closing.
Actuellement, la solution pour pallier ce problème est dans un premier temps d'ouvrir l'emballage hermétique et de déballer les produits puis de les reconditionner dans un second emballage hermétique. En ce qui concerne la surveillance des données telles que la température sur le produit contenu dans l'emballage, la technique utilisée est l'utilisation d'un échantillon témoin qui est perforé et dont le contenu est sondé, cet échantillon, servant de référence pour les autres emballages, ne pourra cependant, compte tenu de la perforation et du contact entre le milieu intérieur et le milieu ambiant, être réutilisé, par conséquent, le produit contenu sera perdu.Currently, the solution to overcome this problem is to first open the sealed package and unpack the products and then repackage in a second sealed package. With regard to the monitoring of data such as the temperature on the product contained in the package, the technique used is the use of a sample a sample which is perforated and the contents of which are probed, this sample, serving as a reference for the other packagings, can not, however, in view of the perforation and the contact between the internal environment and the environment, be reused, therefore, the product content will be lost.
Ce problème qui, à ce jour, d'après nos connaissances, n'a pas été résolu, a de fortes conséquences au niveau économique, écologique et bactériologique.This problem, which to this day, according to our knowledge, has not been solved, has major economic, ecological and bacteriological consequences.
Parmi les applications nécessitant des précautions particulières au niveau de l'ouverture et de la fermeture d'un emballage, citons également dans le domaine médical l'aspiration d'une dose prédéfinie de liquide contenue dans un flacon au moyen d'une seringue permettant notamment d'éviter le contact entre le liquide aspiré et le milieu ambiant. Dans cette application, l'emballage est perforé par l'aiguille d'une seringue et ladite dose de liquide est aspirée dans sa totalité par ladite seringue permettant ainsi d'éviter tout contact entre le liquide aspiré et le milieu ambiant et le flacon vide est alors jeté.Among the applications requiring particular precautions in terms of the opening and closing of a package, let us also mention in the medical field the aspiration of a predefined dose of liquid contained in a bottle by means of a syringe allowing in particular avoid contact between the aspirated liquid and the surrounding environment. In this application, the package is perforated by the needle of a syringe and said liquid dose is sucked in its entirety by said syringe thus avoiding contact between the aspirated liquid and the environment and the empty bottle is then thrown.
Cette solution présente donc différents inconvénients et notamment l'emballage ne peut être réutilisé ce qui entraîne des pertes de produit généralement coûteux.This solution therefore has various disadvantages and in particular the packaging can not be reused, which leads to generally costly product losses.
Le but de l'invention est de proposer un dispositif d'ouverture/fermeture d'un emballage hermétique, notamment destiné à la conservation de produits agroalimentaires qui pallie les inconvénients précités et permet d'ouvrir puis de refermer l'emballage hermétique sans qu'il n'y ait de contact entre le milieu intérieur et le milieu ambiant.The object of the invention is to provide a device for opening / closing a hermetic packaging, especially for the preservation of food products that overcomes the aforementioned drawbacks and allows to open and then close the hermetic packaging without that there is no contact between the internal environment and the environment.
Un autre but de la présente invention est de proposer un dispositif d'ouverture/fermeture d'un emballage hermétique, notamment destiné à la conservation de produits agroalimentaires, dans lequel il est possible d'injecter ou d'aspirer des liquides ou semi-liquides hors ou dans l'emballage.Another object of the present invention is to provide a device for opening / closing a hermetic packaging, in particular for preserving agri-food products, in which it is possible to inject or suck liquids or semi-liquids. off or in the package.
Un autre but de la présente invention est de proposer un dispositif d'ouverture/fermeture d'un emballage hermétique, notamment destiné à la conservation de produits agroalimentaires, dans lequel il est possible d'obtenir des données sur le milieu intérieur de l'emballage en empêchant tout contact entre le milieu intérieur et le milieu ambiant.Another object of the present invention is to propose a device for opening / closing a hermetic package, in particular for the preservation of agri-food products, in which it is possible to obtain data on the internal environment of the packaging by preventing any contact between the internal environment and the ambient environment.
Un autre but de la présente invention est de proposer un dispositif d'ouverture/fermeture fiable et dont la mise en oeuvre est aisée.Another object of the present invention is to provide a reliable opening / closing device whose implementation is easy.

Pour cela, ledit au moins un matériau utilisé doit présenter un coefficient d'élasticité élevé et également une dureté moyenne de façon à ce que lesdits moyens d'obturation 4 aient une bonne tenue et que le trou se referme instantanément c'est-à-dire qu'à aucun moment le milieu ambiant n'entre en contact avec le milieu intérieur de l'emballage 3.In the embodiment of Figures 1 to 5, said closure means 4 consist of at least one thermoplastic material advantageously elastomeric type. This thermoplastic material must have specific characteristics allowing when said shutter means 4 are drilled, to close the hole created. For this, said at least one material used must have a high coefficient of elasticity and also an average hardness so that said closure means 4 have a good hold and that the hole closes instantly that is to say say that at no time does the environment come into contact with the inner environment of the
Après différents tests et essais, il a été constaté qu'un matériau présentant des coefficients d'élasticité compris entre 600 et 700 %, voire entre 550 et 650 %, ainsi qu'une dureté comprise entre 35 et 55 shores, voire entre 55 et 90 shores, est particulièrement bien adapté pour former ledit moyen d'obturation 4.After various tests and tests, it has been found that a material having elasticity coefficients of between 600 and 700%, or even between 550 and 650%, and a hardness of between 35 and 55 shores, or even between 55 and 90 shores, is particularly well suited to form said closure means 4.
Dans le cas d'une application d'un emballage hermétique 3 destiné à la conservation de produits agroalimentaires, on choisira avantageusement des moyens d'obturation 4 constitués d'un matériau commercialisé sous la marque « VITAPRENE », ledit matériau présentant une dureté shore voisine de 40 et un coefficient d'élongation voisin de 650 %, la paroi de l'emballage hermétique 4 étant constituée d'un film en polyéthylène ou polyamideIn the case of an application of a
Cela étant, cet exemple est bien entendu non limitatif, à titre d'exemple, il est possible d'utiliser des matériaux commercialisés sous les marques « SANTOPRENE » et « SANDOZ » avec des caractéristiques de dureté et de coefficient d'élongation similaires.However, this example is of course not limiting, for example, it is possible to use materials marketed under the trademarks "SANTOPRENE" and "SANDOZ" with characteristics of similar hardness and elongation coefficient.
Dans l'exemple de réalisation précité, les moyens d'obturation 4 sont constitués par au moins un élément 5 assujetti à la paroi de l'emballage, l'assujettissement est réalisé de préférence par un adhésif de type cyanoacrylate mono-composant à faible viscosité et polymérisation rapide, ce type de colle est notamment commercialisé sous la marque « LOCTITE ».In the aforementioned embodiment, the sealing means 4 are constituted by at least one
Dans l'exemple de réalisation de la figure 1, lesdits moyens d'obturation 4 se présentent sous la forme de rondelles. Les dimensions de la rondelle d'obturation sont déterminées de manière d'une part à être suffisantes pour permettre un positionnement aisé des moyens de percement 2 et d'autre part relativement petite de manière à nécessiter un minium de matière dont le coût est élevé.In the embodiment of Figure 1, said closure means 4 are in the form of washers. The dimensions of the sealing washer are determined firstly to be sufficient to allow easy positioning of the piercing means 2 and secondly relatively small so as to require a minimum of material whose cost is high.
Comme le montre les figures 1 à 5, ladite rondelle d'obturation 5 est réalisée à partir d'un seul matériau.As shown in Figures 1 to 5, said sealing
Cela étant, il est possible d'envisager, en fonction de l'application, l'utilisation d'une rondelle d'obturation 5 réalisée à partir de deux matériaux. En effet, il a été constaté que lorsque le percement s'effectuait sur un emballage souple et/ou dont le contenu n'est pas rigide, il est préférable, pour éviter l'absorption de la matière constituant adite rondelle 5 et pour augmenter l'herméticité de l'emballage au niveau du percement, de réaliser ladite rondelle 5 à partir de deux matériaux.However, it is possible to consider, depending on the application, the use of a sealing
En se reportant à la figure 6, on voit que la rondelle est constituée d'un anneau 15, circonscrivant un disque 14 de telle façon que ledit anneau 15 constitue un cerclage, voire sertissage du disque 14.Referring to FIG. 6, it can be seen that the washer consists of a ring 15 circumscribing a
Ledit anneau 15 présente un coefficient d'allongement inférieur et une rigidité supérieure à celle du disque 14.Said ring 15 has a lower coefficient of elongation and rigidity greater than that of the
A titre d'exemple dans l'état final, l'anneau 15 présente sensiblement un diamètre intérieur de 20 mm et un diamètre extérieur de 24 mm, alors que le diamètre du disque 14 est sensiblement de 20 mm, la rondelle présente alors un diamètre de 24 mm sensiblement.By way of example in the final state, the ring 15 has substantially an internal diameter of 20 mm and an outside diameter of 24 mm, whereas the diameter of the
Les matériaux employés pour ledit anneau 15 et ledit disque 14 sont, de préférence, respectivement un matériau thermoplastique type élastomère de dureté voisine de 70 shores et de coefficient d'élasticité proche de 600, pour l'anneau et un matériau thermoplastique type élastomère de dureté voisine de 40 shores et de coefficient d'élasticité proche de 650, pour le disque.The materials used for said ring 15 and said
Selon un mode de réalisation avantageux, ladite rondelle 5 est obtenue en introduisant un cylindre de la matière constituant le disque 14 à l'intérieur d'un tube de la matière constituant l'anneau 15 et en découpant des tranches d'épaisseur comprise de préférence entre 4 et 10 mm.According to an advantageous embodiment, said
Aux fins de faciliter l'insertion dudit cylindre, on place le tube sous pression de manière à accroître son diamètre intérieur.In order to facilitate the insertion of said cylinder, the tube is placed under pressure so as to increase its internal diameter.
Pour reprendre le cas de l'exemple précédent de la rondelle d'un diamètre 24 mm, on choisit un cylindre de diamètre 20 mm et un tube de diamètre extérieur 20 mm. Ainsi, après son montage à force, le cylindre est sous contrainte et radialement comprimé.To take again the case of the preceding example of the washer of a diameter 24 mm, one chooses a cylinder of diameter 20 mm and a tube of outside diameter 20 mm. Thus, after its forced fitting, the cylinder is under stress and radially compressed.
Cela étant, il a été constaté que l'utilisation d'une rondelle dont le diamètre est compris avantageusement entre 12 et 20 mm, voire 12 et 24 mm, constituait un bon compromis.However, it has been found that the use of a washer whose diameter is advantageously between 12 and 20 mm, or even 12 and 24 mm, was a good compromise.
Il a été constaté que pour obtenir une bonne fermeture de l'emballage garantissant son herméticité, l'épaisseur de la rondelle devait être proportionnelle à son diamètre et avantageusement, le coefficient de proportionnalité est voisin de 3, ainsi dans le cas d'une rondelle dont le diamètre est compris entre 12 et 24 mm, l'épaisseur de ladite rondelle sera comprise, avantageusement entre 4 et 8 mm.It has been found that to obtain a good closure of the package ensuring its hermeticity, the thickness of the washer should be proportional to its diameter and advantageously, the coefficient of proportionality is close to 3, and in the case of a washer whose diameter is between 12 and 24 mm, the thickness of said washer will be included, preferably between 4 and 8 mm.
Selon les applications, ledit dispositif d'ouverture/fermeture 1 permet l'accès au contenu dudit emballage hermétique 3 pour permettre l'injection et/ou l'aspiration de liquide ou semi-liquide dans et/ou hors de l'emballage ou éventuellement permettre d'obtenir des données sur le milieu intérieur de l'emballage 3. A cet effet, on prévoit, au niveau desdits moyens de percement 2, des moyens d'injection et/ou d'aspiration 6. Pour l'obtention des données, on prévoit également au niveau desdits moyens de percement 2 au moins un capteur 7.According to the applications, said opening /
Lesdits moyens d'injection et/ou d'aspiration 6 sont constitués d'une pompe 8 reliée à, d'une part, un ou plusieurs réservoirs destinés soit à contenir des liquides ou semi-liquides à injecter dans ledit emballage 3, soit destiné à recueillir des liquides ou semi-liquides aspirés hors dudit emballage 3 et, d'autre part, un conduit 9 disposé au niveau desdits moyens de percement 2 de façon à permettre l'injection et/ou l'aspiration de liquides ou semi-liquides dans et/ou hors de l'emballage en empêchant tout contact entre le milieu intérieur de l'emballage 3 et le milieu ambiant.Said injection and / or suction means 6 consist of a pump 8 connected to, on the one hand, one or more tanks intended either for contain liquids or semi-liquids to be injected into said
De même, ledit capteur 7 permettant l'obtention de données sur le milieu intérieur de l'emballage est disposé au niveau desdits moyens de percement 2 de manière à empêcher tout contact entre le milieu intérieur de l'emballage et le milieu ambiant, notamment lors de l'obtention des données. Ledit capteur 7 est de préférence relié à un boîtier de commande et de visualisation de données 10.Similarly, said sensor 7 for obtaining data on the inner environment of the package is disposed at said piercing means 2 so as to prevent any contact between the inner environment of the package and the ambient environment, especially when of obtaining the data. Said sensor 7 is preferably connected to a control and
Dans l'exemple de réalisation des figures 1 à 5, lesdits moyens de percement 2 sont constitués d'une aiguille 11 creuse comportant un orifice 12 au niveau de la partie perçant la paroi dudit emballage 3. La forme de ladite aiguille creuse 11 permet notamment l'insertion desdits moyens d'injection et/ou d'aspiration 6, l'injection et/ou l'aspiration des liquides ou semi-liquides se faisant à-travers ledit orifice 12. En effet, ledit orifice 12 permet un contact entre le milieu intérieur de l'emballage 3 et l'intérieur de ladite aiguille 12.In the embodiment of Figures 1 to 5, said piercing means 2 consist of a
Pour ne pas mettre en contact le milieu intérieur de l'emballage 3 et le milieu ambiant, ladite aiguille creuse 11 ne comporte qu'une ouverture constituée par ledit orifice 12. Cet orifice 12 pour empêcher tout contact entre le milieu intérieur de l'emballage 3 et le milieu ambiant a des dimensions déterminées pour que, lors de la perforation, l'orifice ne puisse mettre en contact le milieu intérieur de l'emballage 3 et le milieu ambiant.In order not to bring the inner medium of the
Ainsi, par exemple, dans le cas d'une perforation perpendiculaire au plan défini par ladite paroi, la dimension dudit orifice 12 selon l'axe de perforation est inférieure à la largeur totale desdits moyens de percement 4 et de la paroi dudit emballage 3.Thus, for example, in the case of a perforation perpendicular to the plane defined by said wall, the dimension of said
Dans une variante de l'invention, il est également possible d'envisager un orifice 12 disposant de moyens d'ouverture/fermeture, l'orifice 12 étant alors bouché lorsque l'orifice se trouve à l'extérieur de l'emballage, et ouvert lorsque l'orifice se trouve à l'intérieur de l'emballage.In a variant of the invention, it is also possible to envisage an
En se reportant aux figures 2 à 5, le fonctionnement du dispositif d'ouverture/fermeture 1 est le suivant. Dans une première étape, représentée à la figure 2, lesdits moyens de percement 2 constitués dans l'exemple par l'aiguille creuse 11 sont positionnés de préférence à la verticale desdits moyens d'obturation 4.Referring to Figures 2 to 5, the operation of the opening /
Dans une seconde étape, on réalise le percement desdits moyens d'obturation 4 et de la paroi de l'emballage 3. A cette étape, on constate que la paroi 3 est rompue, on constate également que lesdits moyens d'obturation 4 constitués par ledit élément 5 sont percés.In a second step, the said sealing means 4 and the wall of the
Compte tenu des caractéristiques physiques du matériau utilisé pour ledit élément 5, le rebord 5a de l'élément 5 appuie contre les bords de ladite aiguille 11 empêchant ainsi tout contact entre le milieu intérieur de l'emballage 3 et le milieu ambiant. A ce stade, illustré par la figure 3, l'orifice 12 de ladite aiguille 11 est en contact avec le milieu intérieur de l'emballage 3, il est donc possible d'aspirer ou d'injecter des liquides ou semi-liquides à partir des moyens d'injection et/ou d'aspiration 6. Il est également, à ce stade, possible au moyen du capteur 7 d'obtenir des données sur le milieu intérieur de l'emballage 3 et notamment des mesures de température.Given the physical characteristics of the material used for said
A ce niveau, il est important de souligner que pour garantir l'herméticité de l'emballage, il est avantageux de choisir pour l'aiguille un diamètre représentant approximativement le quart, voire du quart au sixième, du diamètre de la rondelle.At this level, it is important to emphasize that to ensure the hermeticity of the package, it is advantageous to choose for the needle a diameter representing approximately one quarter to one-quarter of the diameter of the washer.
A titre d'exemple, selon un premier mode de réalisation, l'aiguille 11 a un diamètre de 5 mm et définit un conduit interne de 3 mm de diamètre, et la rondelle a un diamètre de 24 mm et une épaisseur de 8 mm. Les moyens d'injection et/ou d'aspiration 6 permettent l'aspiration d'un litre de liquide en 45 secondes.By way of example, according to a first embodiment, the
Selon un second mode de réalisation l'aiguille 11 a un diamètre de 4 mm, et définit un conduit interne de 2 mm de diamètre, et la rondelle a un diamètre de 24 mm et une épaisseur de 8 mm. Les moyens d'injection et/ou d'aspiration 6 permettent l'aspiration d'un litre de liquide en 1 minute.According to a second embodiment, the
Le choix des dimensions de l'aiguille et de la rondelle sera déterminé de manière générale, d'une part, par le temps disponible pour les opérations d'injection et ou d'aspiration et, d'autre part, par les quantités de liquides et ou semi liquides à injecter ou à aspirer.The choice of the dimensions of the needle and the washer will be determined generally, on the one hand, by the time available for the injection and / or suction operations and, on the other hand, by the quantities of liquids and or semi liquids to be injected or aspirated.
Dans une troisième étape, et en se reportant à la figure 4, on a retiré ladite aiguille 11 hors dudit emballage 3. On constate à ce niveau que ledit emballage 3 reste percé. Lors du retrait de l'aiguille 11, le flanc 5a créé par le percement dudit élément 5 épouse la forme de l'aiguille 11, lorsque celle-ci est retirée, les flancs 5a se touchent et le percement est refermé instantanément, les flancs se recollant compte tenu de la ou les matières utilisées pour la rondelle. Ainsi, à aucun moment, le milieu intérieur de l'emballage 3 n'a été en contact avec le milieu ambiant.In a third step, and referring to Figure 4, said
A ce niveau, il est important de noter que, lorsque l'emballage hermétique 3 est un emballage sous vide, ledit flanc 5a est, lors du retrait de ladite aiguille 11, aspiré vers l'intérieur dudit emballage 3, cette aspiration permet d'assurer une herméticité encore supérieure.At this level, it is important to note that, when the
Grâce à la dépression et à la matière de la rondelle 5, il y a en quelque sorte une auto-obturation. On notera que cet effet est encore renforcé, dans le cas de la variante illustrée à la figure 6 dans laquelle l'anneau 15 comprime radialement la matière du disque 14.Thanks to the depression and the material of the
Il est également possible d'envisager dans une variante afin d'améliorer encore l'herméticité de l'emballage de thermo-souder lors du retrait de l'aiguille 11, ledit élément 5. A cet effet, selon un exemple de réalisation préféré, le thermo-soudage est réalisé à partir d'un fer à souder dont l'extrémité est de forme conique permettant de réaliser comme représenté à la figure 5 un cône de matière 13 placé à l'aplomb du percement réalisé dans la paroi de l'emballage 3.It is also possible to envisage in a variant to further improve the hermeticity of the heat-seal packaging during the removal of the
Ce dispositif permet donc, notamment dans le cas où il est destiné à la conservation de produits agroalimentaires, de ne pas avoir à déballer les produits puis à les reconditionner et donc de n'employer qu'un emballage, ce qui procure à ce dispositif un avantage écologique et économique important par rapport aux dispositifs connus.This device therefore allows, especially in the case where it is intended for the conservation of agri-food products, not having to unpack the products and then repackage them and therefore to use only one package, which provides this device a significant ecological and economic advantage over known devices.
La présente invention concerne également un emballage 3 équipé des moyens d'obturation 4 tels que précités.The present invention also relates to a
Naturellement, d'autres modes de réalisation du dispositif auraient pu être envisagés par l'homme du métier sans pour autant sortir de l'objet de l'invention défini par les revendications ci-après.Naturally, other embodiments of the device could have been envisaged by those skilled in the art without departing from the scope of the invention defined by the claims below.
