Description
Elément d'étanchéité, en particulier pour des récipients
dans lesquels un vide est créé.Sealing element, in particular for containers
in which a vacuum is created.
La présente invention concerne un élément d'étanchéité, en particulier pour des récipients à vide introduits dans des réfrigérateurs, des congélateurs ou des appareils analogues. The present invention relates to a sealing element, in particular for vacuum containers inserted in refrigerators, freezers or the like.
Dans le cas de tels appareils, il est connu d'après des dépôts précédents au nom de la Demanderesse de prévoir, dans un compartiment approprié dans une cuve de réfrigérateur, un tiroir contenant de manière amovible un récipient dans lequel un vide est créé. Le compartiment est avantageusement maintenu d'une manière connue à une température proche de OOC et convient, en particulier pour le stockage de denrées alimentaires. Ces denrées stockées dans un récipient à vide sont conservées dans des conditions optimales. In the case of such devices, it is known from previous filings in the name of the Applicant to provide, in an appropriate compartment in a refrigerator tank, a drawer removably containing a container in which a vacuum is created. The compartment is advantageously maintained in a known manner at a temperature close to OOC and is suitable, in particular for the storage of foodstuffs. These foodstuffs stored in an empty container are kept in optimal conditions.
Le récipient à vide comprend un corps inférieur destiné à être fermé d'une manière étanche par un couvercle. On obtient l'étanchéité en prévoyant sur le bord du couvercle un joint qui coopère avec le bord du corps du récipient. The vacuum container comprises a lower body intended to be sealed by a cover. Sealing is obtained by providing a seal on the edge of the cover which cooperates with the edge of the container body.
Le joint comprend avantageusement une première section tirée par-dessus le bord périphérique du couvercle et une seconde section comportant une lèvre qui s'étend à partir du corps du joint parallèlement au bord périphérique, afin de coopérer avec le bord du corps du récipient. The seal advantageously comprises a first section drawn over the peripheral edge of the cover and a second section comprising a lip which extends from the body of the seal parallel to the peripheral edge, in order to cooperate with the edge of the body of the container.
Un tel joint permet d'obtenir une bonne étanchéité et assure l'obtention d'un bon vide à l'intérieur du récipient. Such a seal makes it possible to obtain a good seal and ensures that a good vacuum is obtained inside the container.
Cependant, au cours du temps et suite à des ouvertures répétées du récipient, le joint tend à perdre ses caractéristiques d'étanchéité avec pour résultat que la conservation des denrées alimentaires dans le récipient n'est plus optimale à cause des rentrées d'air dans ce récipient. However, over time and following repeated opening of the container, the seal tends to lose its sealing characteristics, with the result that the preservation of the foodstuffs in the container is no longer optimal due to the return of air in this container.
L'invention a par conséquent pour but de procurer un élément d'étanchéité ou joint qui permette d'obtenir l'étanchéité souhaitée, même longtemps après son installation. The object of the invention is therefore to provide a sealing element or seal which makes it possible to obtain the desired sealing, even long after its installation.
L'invention a également pour but de procurer, en particulier pour un récipient à vide ou pour des récipients contenant des gaz différents de l'atmosphère dans laquelle ces récipients sont placés, ces gaz étant également à une pression différente de celle de l'atmosphère, un élément d'étanchéité qui empêche toute sortie ou rentrée de gaz par rapport au récipient, même longtemps après son installation. The invention also aims to provide, in particular for an empty container or for containers containing gases different from the atmosphere in which these containers are placed, these gases also being at a pressure different from that of the atmosphere. , a sealing element which prevents any exit or re-entry of gas in relation to the container, even long after its installation.
L'invention a également pour but de procurer un joint ou un élément d'étanchéité du type précité qui soit peu coûteux à fabriquer, fiable à l'usage, simple à utiliser et qui conserve ses caractéristiques propres, même après que le récipient sur lequel il est monté ait été ouvert un grand nombre de fois. The invention also aims to provide a seal or a sealing element of the aforementioned type which is inexpensive to manufacture, reliable in use, simple to use and which retains its own characteristics, even after the container on which it has been mounted has been opened a large number of times.
Ces buts ainsi que d'autres encore qui apparaîtront clairement aux yeux du spécialiste sont atteints par un élément d'étanchéité ou un joint du type précité comprenant un corps pourvu, sur une extrémité latérale, d'une lèvre ou d'une saillie partant de ce corps, cette lèvre étant disposée parallèlement au joint et tout le long du bord de celui-ci, caractérisé en ce qu'il comprend, au moins sur une face de son corps, au moins une autre lèvre espacée de la lèvre située le long de son bord, cette autre lèvre étant parallèle audit bord. L'invention ressortira clairement du dessin qui est fourni à titre d'exemple non limitatif et dans lequel
la Fig. 1 est une vue en coupe en perspective d'une forme d'exécution d'un élément d'étanchéité conforme à l'invention, et
la Fig. 2 illustre un exemple de l'application de l'élément d'étanchéité de la Fig. 1.These and other objects which will appear clearly to the specialist are achieved by a sealing element or a seal of the aforementioned type comprising a body provided, on a lateral end, with a lip or a projection extending from this body, this lip being arranged parallel to the joint and all along the edge thereof, characterized in that it comprises, at least on one face of its body, at least one other lip spaced from the lip situated along from its edge, this other lip being parallel to said edge. The invention will emerge clearly from the drawing which is provided by way of nonlimiting example and in which
Fig. 1 is a perspective sectional view of an embodiment of a sealing element according to the invention, and
Fig. 2 illustrates an example of the application of the sealing element of FIG. 1.
Comme le montre la Fig. 1, l'élément d'étanchéité ou joint eonforme à l'invention est indiqué, dans son ensemble, par 1. As shown in Fig. 1, the sealing element or seal according to the invention is indicated, as a whole, by 1.
Dans la forme d'exécution particulière représentée au dessin, le joint 1 comprend un corps 2 fait d'une matière élastiquement déformable et comportant une première section 3 pourvue de deux parties parallèles superposées 4 et 5 délimitant un espace 6. Les parties 4 et 5 sont reliées à une seconde section 7 du corps 2 délimitant une cavité en substance cylindrique 8 et se terminant dans un bord périphérique arrondi 9. La seconde section 7 comprend des saillies périphériques ou lèvres 10 en substance triangulaires en coupe, qui s'étendent tout le long du bord 9 du corps 2. Les lèvres 10 partent de deux faces opposées 11 et 12 du corps 2 et sont inclinées par rapport à ces faces dans un sens dirigé vers l'extérieur du bord 9, ce bord 9 étant le bord libre du joint 1, comme le montre la Fig. 2. In the particular embodiment shown in the drawing, the seal 1 comprises a body 2 made of an elastically deformable material and comprising a first section 3 provided with two superimposed parallel parts 4 and 5 delimiting a space 6. Parts 4 and 5 are connected to a second section 7 of the body 2 delimiting a substantially cylindrical cavity 8 and ending in a rounded peripheral edge 9. The second section 7 comprises peripheral projections or lips 10 in substantially triangular section, which extend all the way along the edge 9 of the body 2. The lips 10 start from two opposite faces 11 and 12 of the body 2 and are inclined relative to these faces in a direction directed towards the outside of the edge 9, this edge 9 being the free edge of the seal 1, as shown in Fig. 2.
Les extrémités libres 13 et 14 des parties 4 et 5 sont coudées de manière à etre disposées en face l'une de l'autre. The free ends 13 and 14 of parts 4 and 5 are bent so as to be arranged opposite one another.
Suivant la présente- invention, sur au moins une des faces 11 et 12 du corps 2 et, spécifiquement, en correspondance avec les parties 4 et 5 est prévue au moins une autre lèvre disposée parallèlement au bord 9 du corps 2. According to the present invention, on at least one of the faces 11 and 12 of the body 2 and, specifically, in correspondence with the parts 4 and 5, at least one other lip is provided, arranged parallel to the edge 9 of the body 2.
Plus particulièrement, sur la Fig. 1, à chaque face 11 et 12 sont associées un certain nombre de lèvres 16A, B, C qui délimitent en substance une série de chambres d'expansion disposées en succession. Sous ce rapport, les lèvres 16A, B et C sont espacées par des régions 17 servant de compartiments de retenue pour l'air qui passe éventuellement au-delà des crêtes des lèvres 3. More particularly, in FIG. 1, each face 11 and 12 are associated with a number of lips 16A, B, C which essentially define a series of expansion chambers arranged in succession. In this respect, the lips 16A, B and C are spaced apart by regions 17 serving as retaining compartments for the air which possibly passes beyond the crests of the lips 3.
Ces dernières sont inclinées pour rendre difficile leur franchissement par de l'air ou d'autres fluides. Leur inclinaison (qui rend les lèvres 16A, B et C en substance parallèles aux lèvres 10 le long du bord 9 du corps 2) est dirigée vers le bord 9 du joint.The latter are inclined to make it difficult to cross them with air or other fluids. Their inclination (which makes the lips 16A, B and C substantially parallel to the lips 10 along the edge 9 of the body 2) is directed towards the edge 9 of the joint.
Un exemple de l'application de la présente invention est illustré sur la Fig. 2, dans laquelle les parties correspondant à celles de la Fig. 1 sont désignées par les mêmes chiffres de référence. An example of the application of the present invention is illustrated in FIG. 2, in which the parts corresponding to those of FIG. 1 are designated by the same reference numerals.
La figure en cours d'examen montre un compartiment 20 d'un réfrigérateur, congélateur ou appareil analogue qui est maintenu d'une manière connue à une température proche de 0 C. The figure under examination shows a compartment 20 of a refrigerator, freezer or similar device which is maintained in a known manner at a temperature close to 0 C.
Le compartiment 20 est pourvu de sa propre porte 21 qui est reliée à un support ou panier 22 pouvant coulisser sur des glissières 23 associées aux parois du compartiment. The compartment 20 is provided with its own door 21 which is connected to a support or basket 22 which can slide on slides 23 associated with the walls of the compartment.
Un récipient 24, dans lequel un vide est créé, est retenu de manière amovible dans le panier 22. A container 24, in which a vacuum is created, is detachably retained in the basket 22.
D'une manière plus spécifique, le récipient comprend un corps inférieur 25 destiné à être fermé d'une manière étanche par un couvercle 26. More specifically, the container comprises a lower body 25 intended to be sealed by a cover 26.
Le corps 25 comprend, dans sa paroi d'extrémité 27, un conduit (non représenté) qui s'ouvre d'une manière connue dans un élément suceur (ou simplement un suceur) 28 prévu à l'extérieur du corps 25 et fixé à celle-ci de n'importe quelle manière connue. The body 25 comprises, in its end wall 27, a duct (not shown) which opens in a known manner in a suction element (or simply a nozzle) 28 provided outside the body 25 and fixed to this in any known manner.
Ce suceur coopère avec une plaque 29 dans laquelle s'ouvre, au niveau d'une ouverture appropriée non représentée, un conduit 30 raccordé à une pompe à vide (également non représentée) occupant une position appropriée dans le réfrigérateur ou l'appareil analogue. This nozzle cooperates with a plate 29 in which opens, at a suitable opening not shown, a conduit 30 connected to a vacuum pump (also not shown) occupying an appropriate position in the refrigerator or the like.
La plaque 29 est supportée par une console en substance en L élastiquement déformable 31, fixée à un élément 32 installé transversalement au-dessus du récipient 24 et fixé aux parois du compartiment 20 d'une manière connue. The plate 29 is supported by a substantially elastically deformable L-shaped console 31, fixed to an element 32 installed transversely above the container 24 and fixed to the walls of the compartment 20 in a known manner.
Le couvercle 26 porte latéralement deux éléments ou ergots 40 propres à coulisser dans des cames ou des rainures de guidage 41 ménagées dans des panneaux 42 fixés rigidement aux parois du compartiment 20. Grâce à cette construction, lorsque la porte 21 est ouverte, le couvercle 26 se sépare du corps 25, ce qui casse le vide régnant dans le récipient 24. The cover 26 laterally carries two elements or pins 40 capable of sliding in cams or guide grooves 41 formed in panels 42 rigidly fixed to the walls of the compartment 20. Thanks to this construction, when the door 21 is open, the cover 26 separates from the body 25, which breaks the vacuum in the container 24.
Conformément au modèle d'utilité, le joint d'étanchéité 1 est installé le long du bord périphérique 50 du couvercle 26. According to the utility model, the seal 1 is installed along the peripheral edge 50 of the cover 26.
D'une manière spécifique, la première section 3 de ce joint d'étanchéité, comprenant les deux parties planes 4 et 5 superposées parallèlement, est tirée par-dessus le bord du couvercle. A cet effet, la première section 3 du joint 1 est pressée sur le bord 50 du couvercle, de sorte que les extrémités libres 13 et 14 des parties 4 et 5 se séparent l'une de l'autre afin de permettre au bord 50 de pénétrer dans l'espace 6 du corps de l'élément d'étanchéité. Specifically, the first section 3 of this seal, comprising the two flat parts 4 and 5 superimposed in parallel, is pulled over the edge of the cover. To this end, the first section 3 of the seal 1 is pressed on the edge 50 of the cover, so that the free ends 13 and 14 of the parts 4 and 5 separate from one another in order to allow the edge 50 to penetrate into space 6 of the body of the sealing element.
Cette pénétration se termine lorsque le bord 50 fait contact avec la seconde section 7 du corps 2. This penetration ends when the edge 50 makes contact with the second section 7 of the body 2.
Le joint étant monté sur le bord 50, lorsque le couvercle 26 est fermé sur le corps 25 du récipient, les lèvres 16A, B, C et une des lèvres périphériques 10 coopèrent avec le bord supérieur 25A de la partie 25 du corps du récipient, tandis que l'autre lèvre 10 coopère avec une partie partiellement rehaussée 60 du couvercle 26. The seal being mounted on the edge 50, when the cover 26 is closed on the body 25 of the container, the lips 16A, B, C and one of the peripheral lips 10 cooperate with the upper edge 25A of the part 25 of the body of the container, while the other lip 10 cooperates with a partially raised part 60 of the cover 26.
Si la pompe à vide est à présent mise en oeuvre d'une manière connue, de l'air est aspiré hors du récipient 24. Pendant cette phase d'expulsion de l'air, le joint 1 sur le bord 50 du couvercle 26 permet le maintien du vide grâce à la coopération de la lèvre périphérique 10 avec le bord 25A du corps 25 du récipient, cette lèvre coopérant avec ce bord avant les lèvres 16A, B et C. If the vacuum pump is now operated in a known manner, air is sucked out of the container 24. During this phase of expelling the air, the seal 1 on the edge 50 of the cover 26 allows maintaining the vacuum thanks to the cooperation of the peripheral lip 10 with the edge 25A of the body 25 of the container, this lip cooperating with this edge before the lips 16A, B and C.
A mesure que le vide s'accroît, le couvercle 26 est de plus en plus attiré vers la partie 25, la lèvre 10 se déformant en même temps, grâce à l'élasticité de la matière dont le joint 1 est formé. Pendant ce stade, les lèvres 16A, B et C présentes sur la face 12 du corps 2 du joint 1 font contact avec le bord 25A de ce corps 25. As the vacuum increases, the cover 26 is more and more attracted towards the part 25, the lip 10 deforming at the same time, thanks to the elasticity of the material from which the seal 1 is formed. During this stage, the lips 16A, B and C present on the face 12 of the body 2 of the seal 1 make contact with the edge 25A of this body 25.
Etant donné la structure des lèvres 16A, B et
C, elles définissent en substance des chambres d'expansion qui empêchent toute infiltration d'air de l'extérieur dans le récipient 24 au cours du temps.Given the structure of the lips 16A, B and
C, they essentially define expansion chambers which prevent any infiltration of air from the outside into the container 24 over time.
L'autre lèvre périphérique 10 ainsi que les lèvres 16A, B et C prévues sur la face 11 du corps 2 (coopérant avec la partie 60 du couvercle 26) ne sont pas essentielles dans l'exemple illustré de l'application de l'invention . Dans d'autres applications, elles peuvent cependant contribuer à l'étanchéité du joint 1. The other peripheral lip 10 as well as the lips 16A, B and C provided on the face 11 of the body 2 (cooperating with the part 60 of the cover 26) are not essential in the illustrated example of the application of the invention . In other applications, they can however contribute to the sealing of the seal 1.
En résumé, la ou les lèvres périphériques interviennent en général dès que l'air commence à être aspiré hors du récipient 24, tandis que les lèvres 16A, B et C agissent après ce stade, afin de permettre le maintien dans le temps du vide créé dans le récipient. In summary, the peripheral lip or lips generally intervene as soon as the air begins to be sucked out of the container 24, while the lips 16A, B and C act after this stage, in order to allow the vacuum created to be maintained over time. in the container.
Quoique le joint 1 construit conformément à l'invention soit très utilement appliqué dans le cas décrit plus haut, ce joint peut être utilisé dans tous les cas dans lesquels une étanchéité optimale est requise et doit être maintenue au cours du temps.Although the seal 1 constructed in accordance with the invention is very usefully applied in the case described above, this seal can be used in all cases in which optimum sealing is required and must be maintained over time.
Un joint conforme à la présente invention est simple à construire et à monter et est très fiable à l'usage. A seal according to the present invention is simple to construct and assemble and is very reliable in use.
