A container provided with the inventive device is also disclosed. Said invention is particularly suitable for packing food products, in particular in a liquid, pasty and powder form.

Description

La présente invention concerne un dispositif de fermeture étanche à l'air destiné à coopérer avec un contenant d'un produit à conditionner.The present invention relates to an airtight closure device for cooperating with a container of a product to be packaged.

L'invention concerne également un conteneur équipé d'un tel dispositif.The invention also relates to a container equipped with such a device.

L'invention trouve particulièrement son application dans le domaine de la conservation de produits alimentaires sensibles au contact avec l'air et en particulier des produits liquides, pâteux ou pulvérulents.The invention is particularly applicable in the field of the preservation of food products sensitive to contact with air and in particular liquid products, pasty or powdery.

Notamment, l'invention peut permettre le conditionnement de confiture ou encore de marmelade tout en évitant l'oxydation et la contamination microbienne des denrées alimentaires.In particular, the invention may allow the packaging of jam or marmalade while avoiding oxidation and microbial contamination of foodstuffs.

Dans le domaine des confitures, il est usuel, pour les particuliers, d'utiliser une couche de paraffine pour recouvrir la surface supérieure de la denrée alimentaire à conserver.In the field of jams, it is customary for individuals to use a layer of paraffin to cover the upper surface of the foodstuff to be preserved.

La couche de paraffine a l'avantage d'éviter tout résidu d'air au dessus de la surface de confiture.The paraffin layer has the advantage of avoiding any air residue above the jam surface.

Par contre, la mise en oeuvre de ce type de fermeture est particulièrement fastidieuse et il n'est pas possible de recouvrir ensuite de façon aussi efficace la surface du contenant après première utilisation.On the other hand, the use of this type of closure is particularly tedious and it is not possible to subsequently cover the surface of the container as effectively after first use.

Sur le plan industriel, les pots de confiture sont généralement munis d'un couvercle vissé sur le pot.On the industrial level, jam jars are usually provided with a lid screwed on the pot.

Par exemple, le pot est en verre alors que le couvercle est métallique et rapporté par filetage.For example, the pot is glass while the lid is metal and threaded.

L'avantage de ce type de couvercle est sa simplicité de mise en oeuvre et il aura un caractère refermable à volonté.The advantage of this type of lid is its simplicity of implementation and it will have a resealable character at will.

L'inconvénient est qu'il subsiste une couche d'air interstitielle entre la surface intérieure du couvercle et la surface supérieure du produit conservé dans le pot.The disadvantage is that there is a layer of interstitial air between the inner surface of the lid and the upper surface of the product stored in the pot.

De ce fait, la durée de conservation est raccourcie et ce type de conteneur nécessite généralement l'ajout de conservateurs puissants dans les denrées alimentaires.As a result, the shelf life is shortened and this type of container generally requires the addition of strong preservatives in the foodstuffs.

Le document FR-A-1466453 concerne un récipient portatif pour le stockage des liquides comprenant une cuve et un piston flottant propre à coulisser de manière étanche à l'intérieur de ladite cuve. Ce pistons est similaire au dispositif de fermeture du préambule de la revendication 1 annexée.The document FR-A-1466453 relates to a portable container for the storage of liquids comprising a tank and a floating piston clean to slide in a sealed manner inside said tank. This pistons is similar to the closing device of the preamble of appended claim 1.

Il existe donc un besoin de proposer un dispositif de fermeture étanche à l'air apte à remédier aux inconvénients des systèmes actuels et notamment ceux précédemment mentionnés.There is therefore a need to provide an airtight closure device capable of overcoming the disadvantages of the current systems and in particular those mentioned above.

La présente invention répond à ce besoin en présentant un dispositif de fermeture étanche à l'air tel que défini par la revendication 1, pratique à mettre en oeuvre tout en proposant une mise en place ajustable en hauteur dans le volume intérieur du contenant de sorte à venir au plus près et, avantageusement, en contact de la surface supérieure du produit à conserver.The present invention responds to this need by having an airtight closure device as defined by claim 1, practical to implement while proposing an adjustable placement height in the interior volume of the container so as to come closer and advantageously in contact with the upper surface of the product to be preserved.

Tout en réalisant cette fermeture le dispositif de l'invention peut être facilement enlevé et replacé à volonté au contact de la surface du produit à conserver même si la quantité des denrées alimentaires a été modifiée entre temps.While achieving this closure the device of the invention can be easily removed and replaced at will in contact with the surface of the product to be kept even if the amount of foodstuffs has been changed meanwhile.

Suivant un mode préféré de réalisation de l'invention; le dispositif de fermeture étanche est constitué d'un seul tenant et utilisable d'une seule main de façon très pratique tant en ouverture qu'en fermeture.According to a preferred embodiment of the invention; the sealing device consists of a single piece and can be used with one hand in a very practical way both opening and closing.

Le conteneur de l'invention comporte un contenant 1 par exemple de forme sensiblement cylindrique à section circulaire avec un fond 12 et une ouverture supérieure permettant l'introduction du produit à conditionner.The container of the invention comprises a container 1 for example of substantially cylindrical shape with circular section with a bottom 12 and an upper opening for the introduction of the product to be packaged.

Une paroi interne 13 délimite avec le fond 12 un volume de stockage.An inner wall 13 delimits with the bottom 12 a storage volume.

Le contenant 1 peut être réalisé en matière plastique tel du polypropylène ou encore en verre ou en matière métallique.The container 1 may be made of plastic material such as polypropylene or glass or metal material.

Comme l'illustre la figure 1, un dispositif de fermeture 2 peut être rapporté par l'ouverture supérieure du contenant 1.As illustrated by figure 1 , a closure device 2 can be attached by the upper opening of the container 1.

Le dispositif 2 est présenté plus en détail en figure 2.Device 2 is presented in more detail in figure 2 .

En effet, on a représenté la formation d'une base 3 constitutive de la partie inférieure du dispositif 2 apte à venir clore le volume de stockage du contenant 1.Indeed, there is shown the formation of a base 3 constituting the lower part of the device 2 able to close the storage volume of the container 1.

Comme représenté, le pourtour de la base 3 présente une forme circulaire, polygonale ou autre) et des dimensions sélectionnées pour s'ajuster à celles de la paroi interne 13.As shown, the periphery of the base 3 has a circular shape, polygonal or other) and dimensions selected to fit those of the inner wall 13.

En particulier, on choisira un ajustement très légèrement serré entre le dispositif 2 et la paroi interne 13 de sorte à permettre une mise en place à la main tout en interdisant ensuite un déplacement relatif entre les deux pièces.In particular, we will choose a very slightly tight adjustment between the device 2 and the inner wall 13 so as to allow implementation by hand while then prohibiting a relative movement between the two parts.

On peut aussi utiliser un ajustement très légèrement glissant.One can also use a very slightly slippery fit.

Ainsi, des ajustements du type normalisé ISO H7g6 ou H7h6 peuvent être employés.Thus, adjustments of the ISO standard type H7g6 or H7h6 can be used.

Le pourtour de la base 3 se prolonge avantageusement vers le haut (en référence à l'orientation de la figure 2) par un rebord 2 avantageusement configuré avec un même ajustement relativement à la paroi interne 13 du contenant 1.The periphery of the base 3 is advantageously extended upwards (with reference to the orientation of the figure 2 ) by a rim 2 advantageously configured with the same adjustment relative to the inner wall 13 of the container 1.

Au centre de la base 3, un trou 7 est préservé pour l'évacuation de l'air lors de la phase de mise en place du dispositif 2 dans le contenant 1.In the center of the base 3, a hole 7 is preserved for the evacuation of the air during the phase of placing the device 2 in the container 1.

En regard du trou 7, un bouchon 8 est disposé de sorte à permettre l'obturation du trou 7.Opposite the hole 7, a plug 8 is arranged to allow the closure of the hole 7.

Dans le mode de réalisation préféré illustré, le bouchon 8 est monté en suspension sur une paire de lames 10a, 10b mobiles élastiquement entre une position d'escamotage du bouchon 8 et une position active en obturation du même bouchon 8.In the preferred embodiment illustrated, the plug 8 is mounted in suspension on a pair of blades 10a, 10b elastically movable between a retracted position of the plug 8 and an active position in closure of the same plug 8.

A cet effet, les lames 10a, 10b créent un ensemble déformable élastiquement en flexion avec une position déformée avec une flèche orientée vers le haut lorsque le bouchon est en position inactive (cf figure 2, figure 4, figure 6, 7 et 8).For this purpose, the blades 10a, 10b create an elastically deformable assembly in flexion with a deformed position with an arrow pointing upwards when the cap is in the inactive position (cf. figure 2 , figure 4 , figure 6 , 7 and 8 ).

Au contraire, lorsque le bouchon 8 est en position d'obturation, les lames 10a, 10b sont déformées en flexion avec une flèche orientée vers la base 3 du dispositif 2.On the contrary, when the plug 8 is in the closed position, the blades 10a, 10b are deformed in flexion with an arrow pointing towards the base 3 of the device 2.

Cette position est illustrée à la figure 3 ou encore aux figures 9 et 10.This position is illustrated in figure 3 or to Figures 9 and 10 .

On comprend ainsi que l'ensemble du bouchon 8 et des lames 10a, 10b comporte deux positions statiques (actives et inactives) autour d'un point de modification de l'équilibre, la modification étant produite par une action de l'utilisateur tel que cela sera explicité plus loin.It is thus understood that the assembly of the plug 8 and the blades 10a, 10b comprises two static positions (active and inactive) around a point of modification of the equilibrium, the modification being produced by a user action such that this will be explained later.

On notera que les extrémités distales (périphériques) des lames 10a, 10b sont solidaires de la partie supérieure du rebord 2.Note that the distal (peripheral) ends of the blades 10a, 10b are integral with the upper part of the flange 2.

Bien entendu, la configuration illustrée n'est pas limitative.Of course, the illustrated configuration is not limiting.

On peut en particulier envisager un dispositif 2 avec une pluralité de trous et une pluralité de moyens d'obturation.In particular, it is possible to envisage a device 2 with a plurality of holes and a plurality of closure means.

La base 3 du dispositif 2 est, dans le cas illustré, de forme sensiblement tronconique avec un sommet dirigé vers l'extérieur du conteneur 1.The base 3 of the device 2 is, in the illustrated case, of substantially frustoconical shape with a vertex directed towards the outside of the container 1.

De cette façon, l'air a tendance à être orienté vers la partie centrale de la base lors de la mise en place du dispositif.In this way, the air tends to be oriented towards the central part of the base during the installation of the device.

Son évacuation vers le trou 7 et la suppression de toute freinte sont ainsi permises.Its evacuation to the hole 7 and the removal of any ash are thus allowed.

Le bouchon 8 et le trou 7 ont également avantageusement une section longitudinale sensiblement tronconique avec une orientation inverse à celle de la base 3 c'est-à-dire avec un sommet dirigé vers la face interne 4 de la base 3.The plug 8 and the hole 7 also advantageously have a substantially frustoconical longitudinal section with an orientation opposite to that of the base 3, that is to say with a vertex directed towards the internal face 4 of the base 3.

Une telle configuration du trou 7 et du bouchon 8 assure une grande surface de contact entre ces deux pièces et donc une bonne étanchéité.Such a configuration of the hole 7 and the plug 8 ensures a large contact area between these two parts and therefore a good seal.

Le dispositif 2 peut être réalisé en différentes matières et avantageusement en matière plastique moulable.The device 2 can be made of different materials and advantageously moldable plastic material.

On peut utiliser un dispositif 2 en polypropylène avec une épaisseur de base 3 de l'ordre de 0,5 mm à 1mm de sorte à lui préserver une possibilité de déformation en flexion.It is possible to use a device 2 made of polypropylene with a base thickness 3 of the order of 0.5 mm to 1 mm so as to preserve the possibility of bending deformation.

Cette légère déformabilité facilite la mise en place et l'enlèvement du dispositif de fermeture 2.This slight deformability facilitates the introduction and removal of the closure device 2.

Par ailleurs, elle permet d'appliquer un effort radial du pourtour de la base 3 sur la paroi interne 13 du contenant 1 lorsqu'un effort tendant à l'aplatissement de la base 3 est produit par l'utilisateur.Furthermore, it makes it possible to apply a radial force around the base 3 to the inner wall 13 of the container 1 when a force tending to flatten the base 3 is produced by the user.

La base 3 peut, dans une autre variante, être réalisée en plusieurs matériaux.The base 3 may, in another variant, be made of several materials.

En particulier, la base 3 peut être formée généralement en matière polymère telle du polypropylène et présenter au niveau de son pourtour une matière différente apte à assurer un meilleur glissement et/ou une meilleure étanchéité relativement à la paroi interne 13.In particular, the base 3 may be formed generally of polymeric material such as polypropylene and have at its periphery a different material capable of providing better sliding and / or better sealing relative to the inner wall 13.

Ainsi, le pourtour pourra être réalisé en matériau élastique tel du caoutchouc ayant l'effet d'un joint ou encore être constitué c'est-à-dire en tétrafluoroéthylène de sorte à assurer un contact gras entre la paroi interne 13 et le pourtour.Thus, the periphery may be made of an elastic material such rubber having the effect of a seal or be constituted that is to say, tetrafluoroethylene so as to ensure a fatty contact between the inner wall 13 and the periphery.

Bien entendu, toute autre disposition est envisageable et le choix des matériaux précédemment indiqué n'est pas limitatif de l'invention.Of course, any other arrangement is possible and the choice of materials previously indicated is not limiting of the invention.

Suivant le mode de réalisation illustré aux figures 1 et 2, un couvercle 15 est rapporté sur le reste du conteneur au niveau du rebord supérieur du contenant 1.According to the embodiment illustrated in Figures 1 and 2 a cover 15 is attached to the rest of the container at the upper edge of the container 1.

Le couvercle 15 permet de coiffer l'ensemble du conteneur.The lid 15 makes it possible to cap the entire container.

A titre alternatif, tel que représenté en figure 5, c'est un système empilable qui est constitué en ajustant la dimension du fond 12 des conteneurs de sorte à ce qu'ils puissent être introduits au niveau de l'ouverture supérieure d'un autre conteneur pour produire un empilement.As an alternative, as represented in figure 5 it is a stackable system which is constituted by adjusting the size of the bottom 12 of the containers so that they can be introduced at the top opening of another container to produce a stack.

Une collerette 14 faisant saillie radialement légèrement au dessus du fond 12 constitue un rebord pour l'appui du rebord supérieur de l'ouverture du contenant 1.A flange 14 protruding radially slightly above the bottom 12 constitutes a flange for supporting the upper rim of the opening of the container 1.

On peut ainsi empiler plusieurs conteneurs de configuration semblables ce qui constitue un gain de place non négligeable.It is thus possible to stack several similar configuration containers which is a significant gain in space.

On décrit ci-après plus précisément une possibilité d'enchaînement des étapes de mise en place du dispositif de fermeture 2 relativement à un contenant 1.Hereinafter described more precisely a possibility of sequencing the steps of setting up the closure device 2 relative to a container 1.

Ainsi, en figure 6, on a représenté une préhension de l'utilisateur du dispositif 2 par l'intermédiaire des lames élastiques 10a, 10b ou du bouchon 8.So, in figure 6 the user of the device 2 has been shown to grip the elastic blades 10a, 10b or the plug 8.

Le dispositif 2 est ainsi introduit dans le volume intérieur du contenant 1.The device 2 is thus introduced into the interior volume of the container 1.

Au début de l'introduction, une légère poussée de l'utilisateur sur le dispositif 2 assure sa descente par simple glissement relativement à la paroi interne 13.At the beginning of the introduction, a slight push of the user on the device 2 ensures its descent by simply sliding relative to the inner wall 13.

Durant cette phase, l'air contenu entre la surface supérieure du produit à conditionner 6 et la face interne 4 de la base 3 est chassé par le trou central 7.During this phase, the air contained between the upper surface of the product to be packaged 6 and the inner face 4 of the base 3 is driven out by the central hole 7.

Cette étape est illustrée en figure 7.This step is illustrated in figure 7 .

En figure 8, le dispositif 2 est parvenu jusqu'au contact de la surface supérieure du produit à conditionner 6 et tout air résiduel a été supprimé.In figure 8 , the device 2 has reached the contact of the upper surface of the product to be packaged 6 and any residual air has been removed.

On notera que la forme tronconique de la base 3 assure un mouvement de l'air vers le centre de la base pour une évacuation complète par l'intermédiaire du trou 7.It will be noted that the frustoconical shape of the base 3 ensures movement of air towards the center of the base for complete evacuation via the hole 7.

Le contact entre la surface du produit à conditionner 6 et la base 3 stoppe la descente du dispositif 2.The contact between the surface of the product to be packaged 6 and the base 3 stops the descent of the device 2.

L'utilisateur, continuant à exercer une pression, produit une déformation des lames 10a, 10b et une descente du bouchon 8 à l'intérieur du trou central 7.The user, continuing to exert a pressure, produces a deformation of the blades 10a, 10b and a descent of the plug 8 inside the central hole 7.

Cette configuration est montrée en figure 9.This configuration is shown in figure 9 .

Les lames 10a, 10b se retrouvent dans une position déformée en flexion assurant le maintien en position active du bouchon 8.The blades 10a, 10b are found in a deformed position in bending ensuring that the plug 8 is held in the active position.

Dans cette configuration, aucune couche d'air n'est présente entre le dispositif 2 et le produit à conditionner 6 et la fermeture du trou central 7 interdit tout mouvement du dispositif 2 ainsi retenu par dépression.In this configuration, no air layer is present between the device 2 and the product to be packaged 6 and the closure of the central hole 7 prohibits any movement of the device 2 thus retained by depression.

En figure 10, on a représenté une possibilité de mise en place d'un couvercle 15 coiffant l'ensemble du conteneur.In figure 10 , there is shown a possibility of setting up a lid 15 covering the entire container.
