Description
Perfectionnements aux joints d'étanchéité, notamment pour pichets ou autres récipients analogues.Improvements to seals, in particular for pitchers or other similar containers.
La présente invention est relative à des perfectionnements apportés aux joints d'étanehéité du genre de cieux qu'on utilise sur des brocs, pichets ou autres récipients analogues réalisés par assemblage de deux parties. Bien entendu, on pourrait également utiliser un tel joint pour assurer l'étanchéité de couvercles rapportés. The present invention relates to improvements made to the seals of the type of skies used on jugs, pitchers or other similar containers produced by assembling two parts. Of course, such a seal could also be used to ensure the tightness of attached lids.
On connaît des pichets réalisés en deux pièces et comprenant notamment une partie inférieure en verre sur laquelle on visse une partie supérieure en matière plastique ou analogue, comprenant à la fois la poignée et le bec verseur. On interpose entre ces deux éléments un joint plat ruais, par suite des inévitables déformations de la pièce en matière plastique, l'étanchéité ainsi obtenue est très insuffisante. There are known pitchers made in two parts and comprising in particular a lower part made of glass onto which an upper part made of plastic or the like is screwed, comprising both the handle and the spout. A flat seal is interposed between these two elements, as a result of the inevitable deformations of the plastic part, the seal thus obtained is very insufficient.
L'invention vise à pallier ees inconvénients en réalisant un joint susceptible d'assurer une bonne étan ebéité lorsqu'on le serre entre deux éléments, même si ces derniers ne sont pas géométriquement parfaits. The invention aims to overcome these drawbacks by producing a seal capable of ensuring good airtightness when it is clamped between two elements, even if the latter are not geometrically perfect.
Un joint d'étanchéité selon l'invention comprend deux organes, à savoir, d'une part un anneau sou- pie portant deux faces d'appui annulaires décalées transversalement l'une par rapport à l'autre et une lèvre d'étanehéité dépassant dans le sens axial et, d'autre part, un siège annulaire plus rigide mais toutefois légèrement. déformable sur lequel on encli- quette le joint précité qui est alors maintenu par l'une de ses faces d'appui tandis que l'autre se trouve située en porte-à-faux face à un rebord relativement rigide du siège. On comprend qu'en serrant un tel joint composite entre les deux éléments d'un pichet, on provoque une déformation de l'anneau souple dont la lèvre d'étanchéité tend à gonfler dans le sens radial et à venir s'appliquer de façon étanche contre le bord interne de l'élément corres- pondant. On assure ainsi l'étanchéité par aipplica- tion radiale, après serrage dans le sens axial, entre deux faces dont il importe peu désormais qu', elles soient ou non géométriquement parfaites. A seal according to the invention comprises two members, namely, on the one hand a flexible ring carrying two annular bearing faces offset transversely with respect to one another and a sealing lip protruding in the axial direction and, on the other hand, a more rigid but still slightly annular seat. deformable on which the aforementioned seal is snapped, which is then held by one of its bearing faces while the other is located in a cantilever position facing a relatively rigid edge of the seat. It is understood that by tightening such a composite seal between the two elements of a pitcher, one causes a deformation of the flexible ring whose sealing lip tends to swell in the radial direction and to come to be applied in a sealed manner. against the inner edge of the corresponding element. Sealing is thus provided by radial aipplication, after tightening in the axial direction, between two faces of which it is now irrelevant whether or not they are geometrically perfect.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les carne- téristiques qu'elle présente et les avantages qu', elle est susceptible de procurer
Figure 1 est une vue en élévation d'un pichet équipé d'un joint d'étanchéité selon l'invention;
Figure 2 est une vue partielle, en coupe axiale montrant un détail du joint composite avant serra ge;
Figure 3 est une vue correspondante après serrage;
Figure 4 est une coupe partielle du pichet en cours d'utilisation.
lLe joint d'étanchéité selon l'invention est destiné à équiper un pichet de type connu du genre représenté par exemple en figure 1. Un tel pichet est constitué par un élément inférieur A en verre sur lequel on visse un élément supérieur B auquel sont incorporés une poignée 1 et un bec verseur 2. Cet élément B peut être réalisé par exemple en matière plastique. Dans ce cas, le rebord annulaire 3 qu'on prévoit à l'intérieur. de l'élément B pour venir serrer un joint d'étanchéité quelconque sur le sommet de l'élément A, est sujet à des déformations diverses résultant notamment du retrait des matières plastiques et de leur gauchissemet en cours d'utilisation ou sous l'effet de serrage. Avec les joints plats utilisés jusqu'à ce jour et qu'on presse simplement entre le rebord 3 et le bord supérieur 4 de l'élément A, on obtient donc une étanchéité très défectueuse et, lorsqu'on utilise le pichet comme représenté e figure 4,le liquide s'infiltre à travers le filetage 5 pour s'écouler par l'extérieur du pot dans la zone 6 située à la base de l'élément B.The appended drawing, given by way of example, will make it possible to better understand the invention, the characteristics which it presents and the advantages which it is capable of providing.
Figure 1 is an elevational view of a pitcher equipped with a seal according to the invention;
Figure 2 is a partial view, in axial section showing a detail of the composite seal before tightening;
Figure 3 is a corresponding view after tightening;
Figure 4 is a partial section of the pitcher in use.
The seal according to the invention is intended to equip a pitcher of known type of the kind shown for example in FIG. 1. Such a pitcher consists of a lower glass element A onto which an upper element B is screwed into which are incorporated. a handle 1 and a pouring spout 2. This element B can be made for example of plastic. In this case, the annular rim 3 that is provided inside. element B to tighten any seal on the top of element A, is subject to various deformations resulting in particular from the shrinkage of plastics and their warping during use or under the effect Clamping. With the flat gaskets used to date and simply pressing between the rim 3 and the upper edge 4 of the element A, a very defective seal is obtained and, when the pitcher is used as shown in figure 4, the liquid infiltrates through the thread 5 to flow out from the outside of the pot into the area 6 located at the base of the element B.
