Description
L'objet de l'invention concerne un bouchon fonctionnel en résine synthétique expansée. The object of the invention relates to a functional stopper in expanded synthetic resin.
I1 est destiné à permettre d'obtenir une étanchéité directionnelle et sélective afin de s'opposer à l'écoulement des fluides liquides, mais en laissant à l'air et aux fluides gazeux un libre passage d'échappement. I1 is intended to make it possible to obtain a directional and selective seal in order to oppose the flow of liquid fluids, but leaving the air and the gaseous fluids a free passage of exhaust.
Actuellement la qualités des lièges se dégradant de plus en plus, a amené l'utilisation des bouchons en matières plastiques expansés. Ces nouveaux produits présentent lors des opérations de bouchage, surtout avec des appareillages mécaniques, un comportement très irrégulier découlant du fait qu'on utilise pour le bouchage. l'élasticité de la matière synthétique qui est comprimée lors de son introduction de sorte que seul son changement de volume sert à l'étanchéité;ll s'en suit alors que s'ils sont trop étanches, la pression interne de l'air le refoule, par suite s'ils présentent des irrégularités, le liquide fuit. Currently the qualities of corks degrading more and more, has led to the use of stoppers in expanded plastics. These new products exhibit very irregular behavior during capping operations, especially with mechanical equipment, due to the fact that they are used for capping. the elasticity of the synthetic material which is compressed during its introduction so that only its change in volume is used for sealing; it follows then that if they are too tight, the internal pressure of the air repels, consequently if they present irregularities, the liquid leaks.
Le produit suivant 1 'invention supprime ces inconvénients et permet une utilisation fiable des bouchons en résines synthétiques expansées, telles le polyéthylène, ethy-vinyl acétate etc..., de façon à laisser s'échapper l'air lors des bouchages automatiques et à arrêter tout écoulement du fluide. The product according to the invention eliminates these drawbacks and allows reliable use of plugs made of expanded synthetic resins, such as polyethylene, ethyl vinyl acetate, etc., so as to allow air to escape during automatic closings and to stop all fluid flow.
I1 est constitué par la confection sur toute la périphérie verticale du bouchon d'une série d' aspérités attenantes mais distinctes créant des labyrinthes le long de la paroi afin d'occasionner pour le fluide liquide une perte de charge telle qu'il ne peut s'écouler; sont annulés, les effets des capillarités ascendantes ou descendantes alors que le fluide gazeux à un passage. I1 is constituted by the confection on all the vertical periphery of the stopper of a series of contiguous but distinct asperities creating labyrinths along the wall in order to cause for the liquid fluid a pressure drop such that it cannot s 'flow out; are canceled, the effects of ascending or descending capillarities while the gaseous fluid has a passage.
Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention:
La figure 1 représente vue en élévation et en coupe 1' assemblage du bouchon pourvu de ses rugosités périphériques avec le goulot.In the appended drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention:
Figure 1 shows an elevational view in section 1 assembly of the cap provided with its peripheral roughness with the neck.
La figure 2 est une vue de profil et en coupe d'une forme de relief conférant la rugosité de la paroi du bouchon. Figure 2 is a side view in section of a relief shape imparting the roughness of the wall of the plug.
La figure 3 montre schématiquement la perte de charge arrêtant l'écoulement du fluide liquide. Figure 3 shows schematically the pressure drop stopping the flow of liquid fluid.
La paroi périphérique 1 du bouchon 2 est pourvue d'une série de reliefs constituant des aspérités attenantes 3. The peripheral wall 1 of the plug 2 is provided with a series of reliefs constituting adjoining asperities 3.
Ces aspérités sont préférentiellemént obtenues par la confection d'un moule dont les parois ont des saillies de 3 à 5 centièmes de millimètre juxtaposées et superposées sans solution de continuité. These asperities are preferably obtained by making a mold whose walls have projections of 3 to 5 hundredths of a millimeter juxtaposed and superimposed without any solution of continuity.
Ce moule est préférentiellement en métal fritté ou traité physiquement ou chimiquement ou à parois sablées afin d'obtenir ces "inégalités" de relief présentant une régularité fonctionnelle. This mold is preferably made of sintered metal or physically or chemically treated or with sandblasted walls in order to obtain these "unevenness" of relief having a functional regularity.
Le profil des gravures Fig 2 est préférentiellement constitué par une série juxtaposée d'alvéolages 8, 9 pouvant être circulaires de façon à former des cavités semi-sphériques séparées par des aretes lamellaires 10, 11 qui plaquent contre le goulot. The profile of the engravings in Fig 2 is preferably constituted by a juxtaposed series of openings 8, 9 which can be circular so as to form semi-spherical cavities separated by lamellar ridges 10, 11 which press against the neck.
Il est également possible d'avoir des surfaces de contact plus importantes que les arêtes. It is also possible to have larger contact surfaces than the edges.
Cette rugosité uniforme fait plaquer la périphérie du bouchon sur le goulot 4 à paroi lisse. This uniform roughness causes the periphery of the plug to be pressed onto the smooth-walled neck 4.
Lors de 1' enfoncement par machine automatique ou autre, le bouchon est projeté avec une certaine force. Il comprime l ' air dans la zone 5 située entre le parement inférieur 6 du bouchon et la surface 7 du fluide liquide incompressible. When pushing in by automatic machine or the like, the plug is projected with a certain force. It compresses the air in zone 5 situated between the lower facing 6 of the plug and the surface 7 of the incompressible liquid fluid.
Sous l'effet de cette pression, l'air comprime s ' echap- pe rapidement par les multiples vaisseaux capillaires serpentant le long des saillies sans que les pertes de charges soient suffisantes pour l'arrêter; ce qui s'explique par la compressibilité de l'air et sa détente. Under the effect of this pressure, the compressed air escapes rapidly through the multiple capillary vessels winding along the projections without the pressure drops being sufficient to stop it; which is explained by the compressibility of the air and its relaxation.
Après cet effet de poussée, nombre de vaisseaux capillaires se referment et seules demeurent les inégalités réparties sur toute la surface périphérique. After this pushing effect, a number of capillary vessels close and only the unevenness distributed over the entire peripheral surface remains.
Le fluide liquide peut amorcer un début d'écoulement, aidé en cela par les phénomènes de capillarité, d'électricité statique, ou autres, mais la perte de charge est telle, que les veines capillaires s ' étanchéisent immédiatement. The liquid fluid can initiate a start of flow, aided by capillary phenomena, static electricity, or the like, but the pressure drop is such that the capillary veins immediately seal.
Cette étanchéité est amplifiée du fait que le secteur 5 est sans pression créant une rétention de la masse de fluide sous l'effet de la pression atmosphérique. This tightness is amplified by the fact that the sector 5 is without pressure creating a retention of the mass of fluid under the effect of atmospheric pressure.
Le parcours A, B, figure 3 illustre la perte de charge subie par le fluide qui ne peut s'écouler que parmi les irrégularités capillaires qui "cassent" toute amorce d'attraction et annulent également les tensions superficielles entre la paroi vitrée et la masse synthétique. The course A, B, Figure 3 illustrates the pressure drop undergone by the fluid which can only flow among the capillary irregularities which "break" any initiation of attraction and also cancel the surface tensions between the glass wall and the mass synthetic.
Il est possible d'activer les effets hydrophobes de la masse synthétique, soit en enduisant le bouchon pourvu de ses rugosité par une solution chimique à base de silicones comestible ou autres, soit en introduisant avant moulage, telles substances chimiques appropriées. It is possible to activate the hydrophobic effects of the synthetic mass, either by coating the stopper provided with its roughness with a chemical solution based on edible silicones or others, or by introducing before molding, such appropriate chemical substances.
Le moulage des bouchons synthétiques avec paroi rugueuse s ' effectue avec les procédés classiques d'injections, mais avec des faces de contact préalablement gravées de reliefs continus et attenants. The molding of synthetic stoppers with a rough wall is carried out with conventional injection methods, but with contact faces previously engraved with continuous and adjoining reliefs.
Toutefois les formes, dimensions et dispositions des différents éléments, comme d'ailleurs les matières utilisées pour leur fabrication, comme les procédés de gravure des moules pourront varier dans la limite des équivalents, sans changer pour cela la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements, as moreover the materials used for their manufacture, such as the methods of engraving molds may vary within the limit of equivalents, without changing the general conception of the invention which to be described.
