Description

Description Dispositif de fermeture étanche pour conteneur Description Watertight closure device for container
[0001] 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.
[0002] L'invention concerne également un conteneur équipé d'un tel dispositif. [0003] 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 [0004] 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. [0005] 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. [0006] La couche de paraffine a l'avantage d'éviter tout résidu d'air au dessus de la surface de confiture. [0007] Par contre, la mise en œuvre 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. [0008] Sur le plan industriel, les pots de confiture sont généralement munis d'un couvercle vissé sur le pot [0009] Par exemple, le pot est en verre alors que le couvercle est métallique et rapporté par filetage. [0010] L'avantage de ce type de couvercle est sa simplicité de mise en œuvre et il aura un caractère refermable à volonté. [0011] 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. [0012] 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 [0013] II 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. [0014] La présente invention répond à ce besoin en présentant un dispositif de fermeture étanche à l'air pratique à mettre en œuvre 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 [0015] 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 [0016] 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 [0017] D'autres buts et avantages apparaîtront dans la description qui suit qui présente un mode de réalisation préféré de l'invention qui n'est cependant pas limitatif. [0018] La présente invention concerne un dispositif de fermeture étanche à l'air destiné à coopérer avec un contenant d'un produit à conditionner, caractérisé par le fait qu'il présente une base dont le pourtour est ajustable à la paroi interne du contenant de sorte à permettre la mise en contact de la face interne de la base et du produit par dé¬ placement de la base comprenant au moins un trou d'évacuation d'air obturable après la mise en place de la base [0019] Ce dispositif de fermeture peut se présenter suivant des variantes non limitatives énoncées ci-après • [0020] - la base est en matériau semi-rigide déformable élastiquement lors de la mise en place. [0021] le pourtour de la base est prolonge par un rebord oriente vers la face externe de la base [0022] - le rebord présente le même ajustement que le pourtour relativement à la paroi interne du contenant. [0023] - la face interne de la base est de forme tronconique avec un sommet orienté dirigé vers l'extérieur du dispositif. [0024] - il comporte un trou central au travers de la base et un bouchon pour son obturation. [0025] - le trou central et le bouchon sont de formes tronconiques complémentaires avec un sommet dirigé vers la face interne de la base [0026] le bouchon est monté sur la base en suspension au dessus du trou par au moins une lame élastique déformable entre une position dans laquelle le bouchon est mactif et une position dans laquelle le bouchon est actif en obturation. [0027] - il comporte au moins deux lames réparties autour du trou. [0028] - les lames sont solidaires par leur extrémité périphérique du rebord [0029] - les lames sont configurées pour être sollicitées en flexion avec une flèche orientée vers l'extérieur de la base lorsque le bouchon est en position inactive et avec une flèche orientée vers la base lorsque le bouchon est en position active d'obturation [0030] - le pourtour est en matériau élastomère [0031 ] - le pourtour est en tétrafluoroéthylène. [0032] L'invention concerne également un conteneur à fermeture étanche à l'air comportant un contenant pour un produit à conditionner et un dispositif de fermeture selon l'invention. [0033] Ce conteneur peut se présenter suivant les modes de réalisation préfères introduits ci-après [0034] - le pourtour de la base présente un ajustement serre mais autorisant la mise en place à la main relativement à la paroi interne du contenant [0035] la paroi interne du contenant et le pourtour sont circulairesThe invention also relates to a container equipped with such a device. 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 In particular, the invention can allow the packaging of jam or marmalade while avoiding oxidation and microbial contamination of food. 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 keep. The paraffin layer has the advantage of avoiding any air residue above the jam surface. By cons, the implementation of this type of closure is particularly tedious and it is not possible to then cover as effectively the surface of the container after first use. On the industrial front, the jam jars are generally provided with a lid screwed on the pot For example, the pot is made of glass while the lid is metal and threaded. The advantage of this type of cover is its simplicity of implementation and it will have a resealable character at will. The disadvantage is that there is an interstitial air layer between the inner surface of the lid and the upper surface of the product stored in the pot. Therefore, the shelf life is shortened and this type of container usually requires the addition of powerful preservatives in foodstuffs [0013] There is therefore a need to provide a suitable airtight closure device to overcome the disadvantages of the current systems and in particular those mentioned above. The present invention responds to this need by having a practical airtight closure device 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. 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 preserved even if the quantity of the foodstuffs has been modified in the meantime [0016] According to a preferred embodiment of the invention, the sealing device consists of a [0017] Other objects and advantages will become apparent from the following description, which presents a preferred embodiment of the invention which is not suitable for use in one hand. however not limiting. The present invention relates to an airtight closure device for cooperating with a container of a product to be packaged, characterized in that it has a base whose circumference is adjustable to the inner wall of the container. so as to allow contacting the inner face of the base and the product by dé¬ placement of the base comprising at least one obturable air evacuation hole after the establishment of the base [0019] This device The closure may be in the following non-limiting variants : [0020] the base is made of elastically deformable semi-rigid material during placement. The periphery of the base is extended by a rim oriented towards the outer face of the base [0022] - the rim has the same adjustment as the periphery relative to the inner wall of the container. - The inner face of the base is of frustoconical shape with an oriented top directed towards the outside of the device. - It has a central hole through the base and a plug for its closure. [0025] the central hole and the stopper are of complementary frustoconical shape with a top directed towards the inner face of the base; the stopper is mounted on the base suspended above the hole by at least one deformable elastic blade between a position in which the plug is macif and a position in which the plug is active shutter. [0027] it comprises at least two blades distributed around the hole. - The blades are secured by their peripheral end of the flange - the blades are configured to be biased in bending with an arrow facing outwardly of the base when the cap is in the inactive position and with an arrow oriented to the base when the plug is in the active position shutter [0030] - the periphery is elastomeric material [0031] - the periphery is tetrafluoroethylene. The invention also relates to a container with airtight closure comprising a container for a product to be packaged and a closure device according to the invention. This container can be presented according to the preferred embodiments introduced below [0034] - the periphery of the base has a tight fit but allowing the introduction by hand relative to the inner wall of the container [0035] the inner wall of the container and the periphery are circular
[0036] - il comporte un couvercle coiffant le rebord supérieur du contenant [0037] - le fond du contenant est configure pour pouvoir coopérer en superposition avec le rebord supérieur d'un contenant similaire [0038] Les dessins ci-joints sont donnes à titre d'exemples et ne sont pas limitatifs de l'invention Ils représentent seulement un mode de réalisation de l'invention et permettront de la comprendre aisément [0039] La figure 1 illustre les composants du conteneur de l'invention en éclate dans un mode de réalisation préfère[0036] it comprises a lid covering the upper rim of the container [0037] the bottom of the container is configured so that it can cooperate in superposition with the upper rim of a similar container [0038] The attached drawings are given as EXAMPLES AND NOT LIMITING THE INVENTION They represent only one embodiment of the invention and will make it easy to understand it. FIG. 1 illustrates the components of the container of the invention explodes in a realization prefers

[0047] Le conteneur de l'invention comporte un contenant 1 par exemple de forme sen¬ siblement cylindrique à section circulaire avec un fond 12 et une ouverture supérieure permettant l'introduction du produit à conditionnerThe container of the invention comprises a container 1, for example of sen¬ sibly cylindrical shape circular section with a bottom 12 and an upper opening for the introduction of the product to be packaged
[0048] Une paroi interne 13 délimite avec le fond 12 un volume de stockage [0049] Le contenant 1 peut être réalise en matière plastique tel du polypropylene ou encore en verre ou en matière métallique [0050] Comme l'illustre la figure 1, un dispositif de fermeture 2 peut être rapporte par l'ouverture supérieure du contenant 1An inner wall 13 delimits with the bottom 12 a storage volume [0049] The container 1 may be made of plastic such as polypropylene or glass or metal material [0050] As shown in Figure 1, a closing device 2 can be reported through the upper opening of the container 1
[0051] Le dispositif 2 est présente plus en détail en figure 2. [0052] 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 [0053] Comme représente, 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. [0054] 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. [0055] On peut aussi utiliser un ajustement très légèrement glissant. [0056] Ainsi, des ajustements du type normalisé ISO H7g6 ou H7h6 peuvent être employés. [0057] 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. [0058] 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. [0059] En regard du trou 7, un bouchon 8 est disposé de sorte à permettre l'obturation du trou 7. [0060] 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. [0061] 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 mactive (cf figure 2, figure 4, figure 6, 7 et 8). [0062] 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. [0063] Cette position est illustrée à la figure 3 ou encore aux figures 9 et 10. [0064] 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. [0065] On notera que les extrémités distales (périphériques) des lames 10a, 10b sont solidaires de la partie supérieure du rebord 2.The device 2 is present in more detail in FIG. 2. In fact, the formation of a base 3 constituting the lower part of the device 2 capable of closing the storage volume of the container 1 has been shown. As shown, the periphery of the base 3 has a shape (circular, polygonal or other) and dimensions selected to fit those of the inner wall 13. In particular, one will choose a very slightly tight fit between the device 2 and the inner wall 13 so as to allow implementation by hand while at the same time prohibiting a relative movement between the two pieces. We can also use a very slightly slippery adjustment. Thus, adjustments of the ISO standard type H7g6 or H7h6 can be used. The periphery of the base 3 is advantageously extended upwards (with reference to the orientation of Figure 2) by a rim 2 advantageously configured with the same adjustment relative to the inner wall 13 of the container 1. [0058] In the center of the base 3, a hole 7 is preserved for the evacuation of the air during the installation phase of the device 2 in the container 1. [0059] Next to the hole 7, a plug 8 is disposed so as to allow the closure of the hole 7. 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 a active position in closing the same cap 8. [0061] For this purpose, the blades 10a, 10b create an elastically deformable assembly in bending with a deformed position with an arrow pointing upwards when the cap is in the mactive position (see FIG. , Figure 4, Figure 6, 7 and 8) . On the contrary, when the plug 8 is in the closed position, the blades 10a, 10b are deformed in flexion with an arrow oriented towards the base 3 of the device 2. [0063] This position is illustrated in FIG. FIGS. 9 and 10 also show that the assembly of the plug 8 and blades 10a, 10b has two static positions (active and inactive) around a point of modification of the equilibrium, the modification being produced by a user action as will be explained later. Note that the distal (peripheral) ends of the blades 10a, 10b are integral with the upper part of the flange 2.
[0066] Bien entendu, la configuration illustrée n'est pas limitative. [0067] On peut en particulier envisager un dispositif 2 avec une pluralité de trous et une pluralité de moyens d'obturation. [0068] 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. [0069] 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. [0070] Son évacuation vers le trou 7 et la suppression de toute freinte sont ainsi permises. [0071] 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 dirige vers la face interne 4 de la base 3. [0072] Une telle configuration du trou 7 et du bouchon 8 assure une grande surface de contact entre ces deux pièces et donc une bonne etanchéite. [0073] Le dispositif 2 peut être réalisé en différentes matières et avantageusement en matière plastique moulable [0074] On peut utiliser un dispositif 2 en polypropylène avec une épaisseur de base 3 de l'ordre de 0,5 mm à lmm de sorte à lui préserver une possibilité de déformation en flexion [0075] Cette légère déformabilité facilite la mise en place et l'enlèvement du dispositif de fermeture 2. [0076] 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'utilisateurOf course, the configuration illustrated is not limiting. In particular, it is possible to envisage a device 2 with a plurality of holes and a plurality of closure means. 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. In this way, the air tends to be oriented towards the part central station when setting up the device. Its evacuation to the hole 7 and the removal of any ash are thus allowed. 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 inner face 4 of the base 3. [1] 0072] Such a configuration of the hole 7 and the plug 8 ensures a large contact area between these two parts and therefore a good sealing. The device 2 may be made of different materials and advantageously moldable plastic material may be used a device 2 made of polypropylene with a base thickness 3 of the order of 0.5 mm to 1 mm so that it Preserving a possibility of bending deformation [0075] This slight deformability facilitates the installation and removal of the closure device 2. [0076] Moreover, it makes it possible to apply a radial force around the periphery of the base 3 to the internal wall 13 of the container 1 when a force tending to flatten the base 3 is produced by the user
[0077] La base 3 peut, dans une autre variante, être réalisée en plusieurs matériaux [0078] 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 étancheite relativement a la paroi interne 13 [0079] Ainsi, le pourtour pourra être réalisé en matériau élastique tel du caoutchouc ayant l'effet d'un joint ou encore être constitue c'est-à-dire en tétrafluoroéthylène de sorte à assurer un contact gras entre la paroi interne 13 et le pourtour.The base 3 may, in another embodiment, be made of several materials In particular, the base 3 may be generally formed of polymeric material such as polypropylene and have at its periphery a different material capable of ensuring better sliding and / or better tightness relative to the inner wall 13 [0079] 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 greasy contact between the inner wall 13 and the periphery.
[0080] Bien entendu, toute autre disposition est envisageable et le choix des matériaux pré¬ cédemment indiqué n'est pas limitatif de l'invention. [0081] Suivant le mode de réalisation illustre aux figures 1 et 2, un couvercle 15 est rapporté sur le reste du conteneur au niveau du rebord supérieur du contenant 1 [0082] Le couvercle 15 permet de coiffer l'ensemble du conteneur [0083] 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 [0084] 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 [0085] On peut ainsi empiler plusieurs conteneurs de configuration semblables ce qui constitue un gain de place non négligeable [0086] 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 [0087] 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. [0088] Le dispositif 2 est ainsi introduit dans le volume intérieur du contenant 1. [0089] 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. [0090] 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. [0091] Cette étape est illustrée en figure 7. [0092] 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. [0093] 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. [0094] Le contact entre la surface du produit à conditionner 6 et la base 3 stoppe la descente du dispositif 2. [0095] L'utilisateur, continuant à exercer une pression, produit une déformation des lamesOf course, any other arrangement is conceivable and the choice of materials previously described is not limiting of the invention. According to the embodiment illustrated in Figures 1 and 2, a lid 15 is attached to the rest of the container at the upper edge of the container 1 [0082] The lid 15 allows to cap the entire container [0083] Alternatively, as shown in Figure 5, it is a stackable system which is formed by adjusting the size of the bottom 12 of the containers so that they can be introduced at the upper opening of another container for producing a stack [0084] A flange 14 projecting radially slightly above the bottom 12 constitutes a flange for the support of the upper rim of the opening of the container 1 [0085] It is thus possible to stack several similar configuration containers. which constitutes a significant gain of space [0086] Hereinafter more precisely, it is described a possibility of sequencing the steps of placing the closure device 2 relative to a container 1. Thus, in Figure 6, there is shown a gripping of the user of the device 2 by means of the elastic blades 10a, 10b or the plug 8. The device 2 is thus introduced into the interior volume of the device. containing 1. [0089] 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. 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 through the central hole 7. [0091] This step is illustrated in FIG. 7. [0092] In FIG. contact the upper surface of the product to be packaged 6 and any residual air has been removed. Note that the frustoconical shape of the base 3 ensures movement of air towards the center of the base for complete evacuation through the hole 7. The contact between the surface of the product to be packaged 6 and the base 3 stops the descent of the device 2. [0095] The user, continuing to exert pressure, produces a deformation of the blades
10a, 10b et une descente du bouchon 8 à l'intérieur du trou central 7. [0096] Cette configuration est montrée en figure 9. [0097] Les lames 10a, 10b se retrouvent dans une position déformée en flexion assurant le maintien en position active du bouchon 8. [0098] 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.10a, 10b and a descent of the plug 8 inside the central hole 7. This configuration is shown in Figure 9. The blades 10a, 10b are found in a deformed position in bending ensuring the holding in position active plug 8. In this configuration, no air layer is present between the device 2 and the product to be packaged 6 and the closing of the central hole 7 prohibits any movement of the device 2 and retained by depression.
[0099] En fi: gure 10, on a représenté coiffant l'ensemble du conteneu[0099] In FIG. 10, there is shown styling the entire container.
