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 opening / closing an airtight packaging, in particular intended for the conservation of 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 specifically intended for hermetic packaging intended for the conservation of products food, it can also be used for the packaging of all other type of product.
On connaít 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.We know of applications in which the opening and closing a package requires special precautions aimed at in particular to avoid contact between the content or the interior environment of packaging and the 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 opening and closing a hermetic packaging for the conservation of food products after their heat treatment. In this first application, we know that after a heat treatment, certain food products reject a juice of cooking or exudate which must be removed from the packaging before marketing of the product. We also know that it can 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 packaging.
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 mentioned above, and also for others reasons such as possible injection of additional products into the packaging, it is necessary to be able to access the products contained in the packaging.
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 health reasons to bring the interior environment of the packaging and the surrounding environment when opening and returning again airtight packaging when closed.
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 in a first time to open the airtight packaging and unpack the products then to repackage them in a second hermetic packaging. In what relates to monitoring data such as temperature on the product contained in the packaging, the technique used is the use of a sample witness which is perforated and whose content is probed, this sample serving as reference for other packaging, may not, however, given the perforation and contact between the interior environment and the environment, be reused, therefore, the product contained 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 date, to our knowledge, has not not resolved, has strong economic and ecological consequences and bacteriological.
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 precautions specific to the opening and closing of a package, also in the medical field the aspiration of a predefined dose of liquid contained in a bottle by means of a syringe allowing in particular to avoid contact between the liquid sucked in and the surrounding environment. In this application, the packaging is punctured by the needle of a syringe and said dose of liquid is aspirated in its entirety by said syringe thus allowing avoid any contact between the aspirated liquid and the ambient environment and the empty bottle is then thrown away.
Cette solution présente donc différents inconvénients et notamment l'emballage ne peut être réutilisé ce qui entraíne des pertes de produit généralement coûteux.This solution therefore has various drawbacks and especially the packaging can not be reused which results in loss of generally expensive product.
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 propose a device opening / closing an airtight packaging, in particular intended for the conservation of food products which overcomes the aforementioned drawbacks and allows you to open and close the hermetic packaging without any contact between the indoor 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 opening / closing device for hermetic packaging, in particular intended for the conservation of food products, in which it is possible to inject or aspirate liquids or semi-liquids out or in packaging.
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 provide a opening / closing device for hermetic packaging, in particular intended for the conservation of food products, in which it is possible to obtain data on the interior of the packaging by preventing any contact between the interior 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 which is easy to use.
D'autres buts et avantages de la présente invention apparaítront au cours de la description qui va suivre qui n'est donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows which is given only as indicative and which is not intended to limit it.

La présente invention est relative à un dispositif d'ouverture/fermeture d'un emballage hermétique, notamment destiné à la conservation de produits agroalimentaires.The present invention relates to a device opening / closing an airtight packaging, in particular intended for the conservation of food products.
Toutefois, ce dispositif s'applique également à des emballages hermétiques destinés à tout autre produit et par exemple à la conservation de produits pharmaceutiques ou chimiques.However, this device also applies to packaging hermetic intended for any other product and for example for the conservation of pharmaceutical or chemical products.
Comme représenté plus particulièrement à la figure 1, le
dispositif d'ouverture/fermeture 1 conforme à l'invention d'un emballage
hermétique 3 comprend des moyens de percement 2 de la paroi dudit
emballage 3. Le dispositif d'ouverture/fermeture 1 comprend également des
moyens d'obturation 4 au-travers desquels on réalise le percement de
l'emballage 3.As shown more particularly in FIG. 1, the
opening /
Selon l'invention, lesdits moyens d'obturation 4 sont aptes à se
refermer après percement lorsque lesdits moyens de percement 2 sont retirés
de manière à empêcher tout contact entre le milieu intérieur de l'emballage 3
et le milieu ambiant.According to the invention, said shutter means 4 are able to
close after piercing when said
Dans l'exemple de réalisation des figures 1 à 5, lesdits moyens
d'obturation 4 sont constitués par au moins un élément 5 assujetti à la paroi
dudit emballage 3. De manière avantageuse, ledit élément 5 est disposé sur le
côté extérieur de manière à faciliter sa localisation.In the embodiment of Figures 1 to 5, said means
Cela étant, notamment dans le cas d'un emballage 3 constitué
d'une paroi transparente, ledit élément 5 peut être placé sur la face intérieure
de ladite paroi.However, in particular in the case of a
L'assujettissement entre ledit élément 5 et la paroi est réalisé
de préférence par collage. Cela étant, tout autre moyen connu de l'homme du
métier dans le domaine de la fixation pourra être envisagé et notamment par
exemple un thermo-soudage dudit élément 5 sur ladite paroi dudit emballage
3.The subjection between said
Cela étant, dans un autre exemple de réalisation de l'invention,
lesdits moyens d'obturation 4 sont intégrés au niveau de la paroi dudit
emballage 3. A cet effet, ledit emballage hermétique 3 pourra être réalisé de
manière avantageuse par bi-injection.However, in another embodiment of the invention,
said
Dans l'exemple de réalisation des figures 1 à 5, lesdits moyens
d'obturation 4 sont constitués d'au moins un matériau thermoplastique
avantageusement de type élastomère. Ce matériau thermoplastique doit
présenter des caractéristiques spécifiques permettant lorsque lesdits moyens
d'obturation 4 sont percés, de refermer le trou créé. 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 means
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 trials, it was found that
material with elastic coefficients between 600 and 700%,
even between 550 and 650%, as well as a hardness between 35 and 55 shores,
even between 55 and 90 shores, is particularly well suited to form said
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
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.That said, this example is of course non-limiting, by way of For example, it is possible to use materials sold under the “SANTOPRENE” and “SANDOZ” brands with characteristics of similar hardness and coefficient of elongation.
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 exemplary embodiment, the sealing means
4 consist of 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 means
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
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 Figure 6, we see that the washer is
consisting 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 a 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.As an example in the final state, the ring 15 has
substantially an inside diameter of 20 mm and an outside diameter of 24
mm, while 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 accroítre 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 resume the case of the previous example of the washer with a diameter of 24 mm, choose a cylinder with a diameter of 20 mm and a tube outside diameter 20 mm. Thus, after being forced-in, 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 was found that the use of a washer which the 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 packaging ensuring its airtightness, the thickness of the washer should be proportional to its diameter and advantageously, the coefficient of proportionality is close to 3, thus in the case of a washer whose diameter is between 12 and 24 mm, the thickness of said washer will be 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.Depending on 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 are constituted
a pump 8 connected to, on the one hand, one or more reservoirs 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 boítier de commande et de
visualisation de données 10.Likewise, said sensor 7 enabling data to be obtained
on the interior of the packaging is disposed at said means of
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 means
piercing 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.To avoid contacting the interior 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.So, 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
consider 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, we carry out the drilling of 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 guarantee the tightness of the packaging, it is advantageous to choose for the needle a diameter representing approximately a quarter, or even a quarter to a sixth, 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 needle and washer dimensions will be generally determined, on the one hand, by the time available for 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 FIG. 4, we have
withdrawn 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 packaging
hermetic 3 is vacuum packaging, said side 5a is, when removing
said
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 consider in a variant so
to further improve the hermeticity of the heat-seal packaging during 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 makes it possible, in particular in the case where it is intended for the conservation of food products, not to have to unpack the products then repackage them and therefore only use one packaging, which gives this device an ecological and significant economic compared to 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 a person skilled in the art without thereby leaving the subject of the invention defined by the claims below.
