Description
COUVERCLE DE CONTENEUR FERME SOUS VIDE ET CONTENEUR RECEVANT LEDIT COUVERCLE.CONTAINER CLOSED VACUUM LID AND CONTAINER RECEIVING SAID LID.
L'invention est du domaine de l'emballage et plus particulièrement de l'emballage sous vide des aliments.The invention is in the field of packaging and more particularly vacuum packaging of food.
L'invention concerne plus précisément un couvercle de conteneur fermé sous vide et le conteneur recevant ledit couvercle.The invention relates more precisely to a container lid closed under vacuum and the container receiving said lid.
La technique de l'emballage sous vide des aliments à l'intérieur d'un conteneur rigide est connue.The technique of vacuum packaging food inside a rigid container is known.
Le brevet FR 2 686 059 (CATRAIN) exploite la mise sous vide du conteneur pour maintenir naturellement le couvercle par dépression en mettant à profit la différence de pression entre l'intérieur du conteneur et la pression atmosphérique.Patent FR 2 686 059 (CATRAIN) exploits the vacuuming of the container to naturally maintain the lid by vacuum by taking advantage of the pressure difference between the interior of the container and atmospheric pressure.
Le brevet européen n° 79101660 propose une installation . pour la fermeture sous vide de boites avec couvercle qui comprend un blocage du couvercle par le vide sur le débouché de la boite puis un sertissage. Le blocage du couvercle étant obtenu par une différence de pression entre l'intérieur sous vide du conteneur et la pression atmosphérique, il apparaît logique pour libérer le couvercle de poinçonner celui- ci en y perçant un orifice. Cependant, aucun des documents de l'art antérieur n'a prévu de doter le couvercle d'organes permettant de supprimer le vide dans le conteneur par perforation du couvercle.European patent n ° 79101660 proposes an installation. for vacuum closing of boxes with lid which includes a blocking of the lid by the vacuum on the outlet of the box then a crimping. The blocking of the lid being obtained by a pressure difference between the vacuum interior of the container and the atmospheric pressure, it seems logical to free the lid from punching it by drilling a hole in it. However, none of the documents of the prior art has provided for providing the cover with members making it possible to eliminate the vacuum in the container by perforating the cover.
Il est connu des couvercles dotés d'origine d'un orifice obturé par un opercule qui, lorsque l'intérieur du conteneur est sous vide, peut être perforé pour mettre l'intérieur du conteneur à la pression atmosphérique. Il est cependant toujours nécessaire d'avoir recours à un outil annexe, poinçon ou autre. Il est connu également des conteneurs pour la conservation des aliments sous vide ou non dont le couvercle métallique est doté d'un système d'ouverture constitué par un anneau fixé au couvercle, qui est prédécoupé sur une ligne venant de cisaillement partiel, d'affaiblissement du métal du couvercle.Lids are known which originally have an orifice closed by a cover which, when the interior of the container is under vacuum, can be perforated to bring the interior of the container to atmospheric pressure. However, it is always necessary to use an auxiliary tool, punch or other. It is also known containers for preserving food under vacuum or not whose metal cover is provided with an opening system constituted by a ring fixed to the cover, which is precut on a line coming from partial shear, weakening cover metal.
Cette forme de réalisation connue n'est généralement pas adaptée à la conservation sous vide profond.This known embodiment is generally not suitable for storage under deep vacuum.
L'affaiblissement du couvercle est opposé à une résistance suffisante du métal du couvercle au différentiel de pression généré par l'obtention du vide surtout lorsqu'il s'agit d'un vide profond qui peut être deThe weakening of the cover is opposed to a sufficient resistance of the metal of the cover to the pressure differential generated by obtaining the vacuum, especially when it is a deep vacuum which can be of
900 à 980 millibars négatif sur pression relative, lequel peut être accru par la conservation au froid du conteneur.900 to 980 millibars negative on relative pressure, which can be increased by keeping the container cold.
L'arrachement du couvercle suivant la zone de cisaillement dont les bords sont tranchants présente un certain danger pour le consommateur.Tearing off the cover along the shear zone whose edges are sharp presents a certain danger for the consumer.
L'inventeur se propose de solutionner ce problème pour faciliter l'ouverture des conteneurs sous vide en utilisant l'aptitude à la mise en atmosphère d'un conteneur à couvercle métallique dont il suffit qu'il soit percé en un point pour qu'il ne soit plus retenu sur le débouché du conteneur.The inventor proposes to solve this problem in order to facilitate the opening of vacuum containers by using the aptitude for placing in the atmosphere of a container with a metallic lid which it is sufficient for it to be pierced at a point for it is no longer retained on the outlet of the container.
L'invention se propose en outre de réaliser de manière simultanée et en une seule opération la mise à la pression atmosphérique du conteneur, l'enlèvement du couvercle et son dépôt au rebut.The invention further proposes to carry out simultaneously and in a single operation the setting at atmospheric pressure of the container, the removal of the lid and its disposal in scrap.
Le couvercle de conteneur selon la présente invention peut être utilisé sur tout type de conteneur rigide en verre ou en métal dont le débouché présente une section suffisante pour l'appui du couvercle et son maintien par la différence de pression.The container cover according to the present invention can be used on any type of rigid glass or metal container, the outlet of which has a section which is sufficient for the support of the cover and its maintenance by the pressure difference.
A cet effet, le couvercle métallique selon l'invention pour conteneur rigide destiné à être mis sous vide pour assurer la conservation des produits contenus et le blocage du couvercle par différentiel de pression sur le débouché du conteneur présentant un bord avec une section de réception du couvercle, se caractérise essentiellement en ce qu'il est doté d'une zone périphérique annulaire ou collerette creuse dont la gorge reçoit un matériau d'étanchéité compressible, que sa paroi est dotée d'une zone de fragilisation à côté de laquelle dispose un anneau fixé sur le couvercle en sorte qu'une traction sur ledit anneau ouvre le couvercle au niveau de la zone de fragilisation.To this end, the metal cover according to the invention for rigid container intended to be evacuated to ensure the conservation of the products contained and the blocking of the cover by pressure differential on the outlet of the container having an edge with a receiving section of the lid, is essentially characterized in that it is provided with an annular peripheral zone or hollow collar whose groove receives a compressible sealing material, that its wall is provided with a embrittlement zone next to which has a ring fixed on the cover so that a pull on said ring opens the cover at the embrittlement zone.
Avantageusement, la zone de fragilisation est obtenue par une ligne de prédécoupe du couvercle sur une faible longueur par exemple de quelques millimètres à une dizaine de millimètres.Advantageously, the embrittlement zone is obtained by a precut line of the cover over a short length, for example from a few millimeters to ten millimeters.
Avantageusement, l'anneau est fixé à plat sur le couvercle par un rivet à proximité de la zone d'affaiblissement de la paroi du couvercle.Advantageously, the ring is fixed flat on the cover by a rivet near the weakening zone of the wall of the cover.
Avantageusement, l'anneau est doté à l'arrière du rivet d'une boucle permettant son soulèvement et le maintien du couvercle et à l'avant du rivet d'une portion rigide qui par basculement de l'anneau perfore la zone d'affaiblissement.Advantageously, the ring is provided at the rear of the rivet with a loop allowing its lifting and the maintenance of the cover and at the front of the rivet with a rigid portion which by tilting the ring pierces the weakened zone. .
D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description ci-après de l'invention donnée à titre d'exemple non limitatif et illustrée par les dessins joints :Other advantages and characteristics of the invention will appear on reading the following description of the invention given by way of nonlimiting example and illustrated by the accompanying drawings:
- la figure 1 est une vue en coupe d'un couvercle selon l'invention ;- Figure 1 is a sectional view of a cover according to the invention;
- la figure 2 est une vue de dessus du couvercle selon l'invention ;- Figure 2 is a top view of the cover according to the invention;
- la figure 3 est une vue en coupe du couvercle selon les figures 1/2 posé sur le débouché d'un conteneur ; - la figure 4 représente un autre type de conteneur.- Figure 3 is a sectional view of the cover according to Figures 1/2 placed on the outlet of a container; - Figure 4 shows another type of container.
Tel que représenté aux dessins annexés, le couvercle est constitué d'un flanc de métal venant d'emboutissage de forme circulaire. Il est doté d'une partie centrale 1 en creux et d'un rebord annulaire périphérique 2 présentant une gorge 3 dont la largeur est égale ou légèrement supérieure à . la section 4 du bord du débouché d'un conteneur 5 tel que représenté à la figure 3. La gorge 3 vient en face de la section 4 du bord du débouché du conteneur 5.As shown in the accompanying drawings, the cover consists of a metal side coming from stamping of circular shape. It has a hollow central part 1 and a peripheral annular rim 2 having a groove 3 whose width is equal to or slightly greater than. section 4 of the edge of the opening of a container 5 as shown in FIG. 3. The groove 3 comes opposite the section 4 of the edge of the opening of the container 5.
Dans la gorge 3 est disposé un matériau 3A d'étanchéité compressible par exemple un caoutchouc collé dans ladite gorge.In the groove 3 is disposed a compressible sealing material 3A, for example a rubber bonded in said groove.
Sur le flanc constituant le couvercle en retrait du rebord annulaire 2 est ménagée une zone d'affaiblissement de la paroi du dit flanc. Préférentiellement, cette zone est obtenue par une prédécoupe non traversante, venant par exemple de cisaillement partiel de l'épaisseur de la paroi du flanc sur une profondeur de quelques centièmes.On the flank constituting the cover set back from the annular rim 2 is provided a weakening zone of the wall of said flank. Preferably, this area is obtained by a non-through precut, for example from partial shearing of the thickness of the wall of the sidewall to a depth of a few hundredths.
Cette prédécoupe schématisée par le trait 7 (figure 2) est effectuée de manière préférentiellement rectiligne sur une faible longueur par exemple de quelques millimètres à une dizaine de millimètres.This precut schematized by the line 7 (Figure 2) is preferably performed rectilinearly over a short length, for example from a few millimeters to ten millimeters.
A proximité de la prédécoupe 7 et en retrait de celle-ci vers le centre du couvercle est monté un anneau 8. L'anneau 8 est fixé au couvercle par un rivet 9.A ring 8 is mounted near the precut 7 and set back from it towards the center of the cover. The ring 8 is fixed to the cover by a rivet 9.
Il est doté d'une boucle 10 vers l'arrière du rivet, c'est à dire orientée vers le centre du couvercle et à l'avant du rivet d'une portion rigide 11.It has a loop 10 towards the rear of the rivet, that is to say oriented towards the center of the cover and at the front of the rivet with a rigid portion 11.
Lors du soulèvement de l'anneau par introduction du doigt de l'utilisateur dans la boucle 10, celui-ci bascule, ce qui provoque une torsion du flanc dont la paroi cède au niveau de la zone d'affaiblissement 7 en provoquant la mise en atmosphère du conteneur et son ouverture. Un équilibre de pression étant obtenu entre l'atmosphère et l'intérieur du conteneur, le couvercle se sépare de lui-même du débouché du conteneur par la même opération et toujours tenu au moyen de l'anneau par l'utilisateur, il peut être mis en rebut sans que sa main puise entrer en contact avec des parties tranchantes qui sont d'ailleurs très réduites et non dissociées du flanc lui-même. Le conteneur tel que représenté en figure 3 a à son débouché une paroi de bord de largeur ou section légèrement inférieure au rebord annulaire 2 et à la gorge 3 du couvercle qui le coiffe.When the ring is lifted by introducing the user's finger into the loop 10, the latter rocks, which causes the sidewall to twist, the wall of which gives way at the weakening zone 7, causing the setting atmosphere of the container and its opening. A pressure balance being obtained between the atmosphere and the interior of the container, the cover separates itself from the outlet of the container by the same operation and always held by means of the ring by the user, it can be discarded without his hand being able to come into contact with sharp parts which are moreover very reduced and not dissociated from the flank itself. The container as shown in Figure 3 has at its outlet an edge wall of width or section slightly smaller than the annular rim 2 and the groove 3 of the cover which covers it.
Sur la paroi de bord du conteneur est ménagée au moins une rainure en creux 12 dans laquelle lors de la fixation du couvercle par dépression qui s'effectue avec une phase de compression du couvercle sur le débouché du conteneur, la matière du joint d'étanchéité pénètre la zone 12. Le conteneur de la figure 3 est de préférence en verre.On the edge wall of the container is provided at least one hollow groove 12 in which during the fixing of the cover by vacuum which takes place with a compression phase of the cover on the outlet of the container, the material of the seal enters zone 12. The container of FIG. 3 is preferably made of glass.
En figure 4 est réalisée une autre forme de conteneur qui est de préférence en métal.In Figure 4 is made another form of container which is preferably made of metal.
Le débouché du conteneur présente un épaulement circulaire suivi d'un retreint, le bord supérieur étant roulé en forme d'anneau 13 de section cylindrique ou en arc de courbe. L'anneau reçoit un couvercle qui est également pourvu d'une gorge périphérique annulaire 3 ouverte vers le débouché du conteneur et dans laquelle est placé le matériau souple d'étanchéité.The opening of the container has a circular shoulder followed by a constriction, the upper edge being rolled in the form of a ring 13 of cylindrical section or in a curved arc. The ring receives a cover which is also provided with an annular peripheral groove 3 open towards the outlet of the container and in which the flexible sealing material is placed.
Avantageusement, la paroi de la gorge présente au moins une nervure circulaire formant une rainure creuse 12 du côté du débouché du conteneur dans laquelle se loge le matériau d'étanchéité comme précédemment décrit. Advantageously, the wall of the groove has at least one circular rib forming a hollow groove 12 on the side of the opening of the container in which the sealing material is housed as previously described.
