Abstract

The fluid transfer comprises a sleeve (1) with an upstream supply end (1a) and a downstream outlet end (1b). The sleeve can be orientated in all directions. It is formed by a succession of articulated segments (11..) constituted by downstream rigid walls (11b..) and upstream deformable wall (11a..). The upstream walls can be partially retracted under the downstream walls allowing compression, expansion or bending of the sleeve. The upstream and downstream walls are inclined to the sleeve interior and connected to the widest diameter by an arch describing a quarter meridian before connecting to the upstream wall. This thus defines a line of inflexion which forms a first articulation for the wall.

Description

La présente invention concerne un dispositif de transfert de fluides.The present invention relates to a fluid transfer device.

Il existe déjà des dispositifs de transfert comprenant notamment un manchon pourvu d'une extrémité amont d'alimentation et d'une extrémité aval d'évacuation éventuellement obturée par un bouchon.There are already transfer devices comprising in particular a sleeve provided with an upstream supply end and a downstream discharge end possibly closed by a plug.

De tels dispositifs sont généralement utilisés sur des récipients de produits liquides visqueux. Dans cette utilisation, l'extrémité amont du manchon communique, en partie basse, avec le récipient sur lequel il est fixé, tandis que son extrémité aval supérieure débouche à l'extérieur selon une direction inclinée par rapport à l'axe dudit récipient.Such devices are generally used on containers of viscous liquid products. In this use, the upstream end of the sleeve communicates, at the bottom, with the container on which it is fixed, while its upper downstream end opens out in a direction inclined relative to the axis of said container.

Cependant dans de tels dispositifs, l'inclinaison ou la courbure du manchon est fixée dès sa fabrication. Dans certains cas, il est prévu une liberté de rotation du manchon selon son axe de révolution, ce qui permet de modifier légèrement l'orientation de l'extrémité aval d'évacuation.However in such devices, the inclination or the curvature of the sleeve is fixed as of its manufacture. In certain cases, a freedom of rotation of the sleeve is provided along its axis of revolution, which makes it possible to slightly modify the orientation of the downstream discharge end.

Toutefois, les possibilités de réglage sont limitées et restent insuffisantes, en particulier pour des applications où il est nécessaire de donner au manchon des géométries complexes en vue d'amener le produit dans des zones difficilement accessibles.However, the adjustment possibilities are limited and remain insufficient, in particular for applications where it is necessary to give the sleeve complex geometries in order to bring the product into areas which are difficult to access.

En outre, les dispositifs traditionnels sont encombrants, du fait même que le manchon fait saillie au-delà de la partie haute du récipient.In addition, traditional devices are bulky, by the very fact that the sleeve projects beyond the upper part of the container.

La présente invention a pour but de résoudre les problèmes techniques précédents ou du moins de les atténuer.The present invention aims to solve the above technical problems or at least to mitigate them.

Ce but est atteint, selon l'invention, au moyen d'un dispositif de transfert de fluides comprenant un manchon pourvu d'une extrémité amont d'alimentation et d'une extrémité aval d'évacuation, éventuellement obturée par un bouchon, caractérisé en ce que ledit manchon est orientable dans toutes les directions et de façon stable, rémanente et réversible, en étant formé d'une succession de segments articulés, constitués d'une paroi aval rigide et d'une paroi amont élastiquement déformable, susceptible de s'escamoter, au moins partiellement, sous ladite paroi aval pour permettre, par déclic, la compression et/ou la flexion dudit manchon.This object is achieved, according to the invention, by means of a fluid transfer device comprising a sleeve provided with an upstream supply end and a downstream discharge end, possibly closed by a plug, characterized in that said sleeve is orientable in all directions and stably, retentive and reversible, being formed of a succession of articulated segments, consisting of a rigid downstream wall and an elastically deformable upstream wall, capable of retract, at least partially, under said downstream wall to allow, by clicking, compression and / or bending of said sleeve.

Selon une caractéristique avantageuse, les parois amont et aval sont inclinées vers l'intérieur du manchon et se raccordent au diamètre le plus large par une arcade.According to an advantageous characteristic, the upstream and downstream walls are inclined towards the inside of the sleeve and are connected to the widest diameter by an arch.

De préférence, l'inclinaison entre les parois amont et aval est, à l'état déplié, comprise entre 30° et 90°.Preferably, the inclination between the upstream and downstream walls is, in the unfolded state, between 30 ° and 90 °.

Ladite arcade est tangente à la paroi aval pour la rigidifier et elle décrit un quart de méridien avant de se raccorder à la paroi amont, en formant ainsi une première articulation pour ladite paroi.Said arch is tangent to the downstream wall to stiffen it and it describes a quarter of the meridian before connecting to the upstream wall, thereby forming a first articulation for said wall.

Selon une autre caractéristique, lesdits segments sont séparés par une gorge périphérique dont le bord aval forme une seconde articulation pour la paroi amont.According to another characteristic, said segments are separated by a peripheral groove whose downstream edge forms a second articulation for the upstream wall.

De manière générale, les génératrices du manchon définissent un cylindre éventuellement de révolution.Generally, the generatrices of the sleeve define a cylinder possibly of revolution.

Selon un mode de réalisation particulier, les parois amont et aval des segments sont tronconiques et se raccordent par une arcade torique de façon à définir des segments sensiblement annulaires.According to a particular embodiment, the upstream and downstream walls of the segments are frustoconical and are connected by a toric arch so as to define substantially annular segments.

Selon un autre mode de réalisation, le manchon a une section constituée de deux demi-cercles réunis par des tronçons de droite tangents.According to another embodiment, the sleeve has a section consisting of two semicircles joined by tangent straight sections.

Selon une variante, l'extrémité aval du manchon comporte un filetage pour le vissage d'un bouchon.Alternatively, the downstream end of the sleeve includes a thread for screwing a plug.

Selon une autre variante, le diamètre des segments, c'est-à-dire, le cas échéant, celui de la surface de raccord en arcade, est variable de l'extrémité amont à l'extrémité aval du manchon.According to another variant, the diameter of the segments, that is to say, if necessary, that of the arcuate connection surface, is variable from the upstream end to the downstream end of the sleeve.

Un autre objet de l'invention est une utilisation du dispositif précédent par intégration dans un conditionnement pour assurer l'évacuation dudit produit à partir d'un récipient de produit liquide.Another object of the invention is a use of the previous device by integration into a packaging to ensure the evacuation of said product from a container of liquid product.

Le dispositif de l'invention permet d'orienter l'extrémité aval par rapport à l'extrémité amont du manchon selon des géométries complexes, stables, rémanentes et réversibles.The device of the invention makes it possible to orient the downstream end relative to the upstream end of the sleeve according to complex, stable, persistent and reversible geometries.

Il peut être utilisé comme accessoire d'un récipient ou comme outil indépendant et peut même servir d'élément de raccordement entre deux tronçons de conduite de fluide.It can be used as an accessory to a container or as an independent tool and can even serve as a connecting element between two sections of fluid pipe.

La compression du manchon permet de réduire l'encombrement global du conditionnement, ce qui présente des avantages sur le plan écologique pour des emballages jetables. Par ailleurs, la flexion du manchon procure à la fois une souplesse et une grande facilité d'utilisation.The compression of the sleeve makes it possible to reduce the overall bulk of the packaging, which has ecological advantages for disposable packaging. Furthermore, the bending of the sleeve provides both flexibility and ease of use.

A l'état replié, le manchon n'occupe donc que très peu de place, ce qui présente, en outre, des avantages sur les plans économique et esthétique. Dans ces conditions, il peut s'intégrer facilement à un conditionnement de produit, en étant équipé d'un bouchon ou bien encapuchonné à l'intérieur d'un couvercle.In the folded state, the sleeve therefore occupies very little space, which has, moreover, advantages from an economic and aesthetic point of view. Under these conditions, it can be easily integrated into a product packaging, by being fitted with a cap or else hooded inside a cover.

Ce dispositif trouve, en particulier, son application dans le domaine des produits d'entretien ou de bricolage, des lubrifiants, des médicaments, des cosmétiques ... .This device finds, in particular, its application in the field of maintenance or DIY products, lubricants, drugs, cosmetics, etc.

L'invention sera mieux comprise à la lecture de la description qui va suivre, accompagnée des dessins sur lesquels :

  • les figures 4a et 4b représentent des vues de profil d'une application du mode de réalisation des figures 1a à 1d, respectivement
dans les positions des figures 1b et 1c.The invention will be better understood on reading the description which follows, accompanied by the drawings in which:
  • Figures 1a, 1b, 1c and 1d show side views of a first embodiment of the device of the invention in different positions;
  • 2a shows a partial sectional view of the embodiment of Figures 1a to 1d in the position of Figure 1a;
  • Figure 2b shows a partial sectional view of the embodiment of Figures 1a to 1d in the position of Figure 1c;

  • Figures 4a and 4b show side views of an application of the embodiment of Figures 1a to 1d, respectively
in the positions of Figures 1b and 1c.

Le dispositif de l'invention tel que représenté sur les figures 1a à 1d est destiné au transfert de fluides et en particulier de liquides.The device of the invention as shown in Figures 1a to 1d is intended for the transfer of fluids and in particular liquids.

A cet effet, il comprend un manchon 1 pourvu d'une extrémité amont 1a d'alimentation en fluide et d'une extrémité 1b d'évacuation dudit fluide.To this end, it comprises a sleeve 1 provided with an upstream end 1a for supplying fluid and with an end 1b for discharging said fluid.

De préférence, l'extrémité amont 1a possède un orifice d'alimentation 10a tandis que l'extrémité aval 1b possède un orifice de distribution 10b, ménagé ici au débouché d'un col 2, réalisé d'une seule pièce avec le manchon 1 ou sous forme d'une pièce rapportee.Preferably, the upstream end 1a has a supply orifice 10a while the downstream end 1b has a distribution orifice 10b, formed here at the outlet of a neck 2, produced in one piece with the sleeve 1 or as an attachment.

Selon l'invention, le manchon 1 est orientable dans toutes les directions à partir de la position dépliée de la figure 1a pour prendre les positions représentées sur les figures 1b, 1c ou 1d.According to the invention, the sleeve 1 can be oriented in all directions from the unfolded position in FIG. 1a to take the positions shown in FIGS. 1b, 1c or 1d.

Le manchon 1 est ici formé, à la manière d'un soufflet, d'une succession de trois segments 11, 12, 13 articulés.The sleeve 1 is here formed, in the manner of a bellows, of a succession of three articulated segments 11, 12, 13.

Les segments 11, 12, 13 sont constitués chacun d'une paroi amont 11a, 12a, 13a, élastiquement déformable et d'une paroi aval 11b, 12b, 13b, rigide. Le paroi amont 11a, 12a, 13a est susceptible de s'escamoter complètement (figure 1b) ou partiellement (figures 1c et 1d) sous la paroi aval 11b, 12b, 13b.The segments 11, 12, 13 each consist of an upstream wall 11a, 12a, 13a, elastically deformable and of a downstream wall 11b, 12b, 13b, rigid. The upstream wall 11a, 12a, 13a is capable of retracting completely (Figure 1b) or partially (Figures 1c and 1d) under the downstream wall 11b, 12b, 13b.

L'escamotage de la paroi amont s'accompagne d'un déclic et permet la compression du manchon 1, selon l'axe X (figure 1b), sa flexion pour amener le col 2, selon l'axe Y faisant un angle β avec l'axe X (figure 1c) ou toute combinaison entre une compression selon X et une flexion pour amener le col 2, selon l'axe Y', faisant un angle θ avec l'axe X (figure 1d). Toutes les positions obtenues par ces déformations sont stables, rémanentes et réversibles.The retraction of the upstream wall is accompanied by a click and allows the compression of the sleeve 1, along the axis X (FIG. 1b), its bending to bring the neck 2, along the axis Y making an angle β with the X axis (Figure 1c) or any combination of compression along X and bending to bring the neck 2 along the Y 'axis, making an angle θ with the X axis (Figure 1d). All the positions obtained by these deformations are stable, remanent and reversible.

La figure 2a représente une vue partielle en coupe du manchon 1 en extension, dans la position de la figure 1a.2a shows a partial sectional view of the sleeve 1 in extension, in the position of Figure 1a.

Les parois amont 11a, 12a et aval 11b, 12b des segments 11,12 sont inclinées vers l'intérieur du manchon 1, en direction de l'axe X et se raccordent au diamètre le plus large par une arcade torique 10 d'axe X.The upstream walls 11a, 12a and downstream 11b, 12b of the segments 11,12 are inclined towards the inside of the sleeve 1, in the direction of the axis X and are connected to the widest diameter by a toric arch 10 of axis X .

Dans un autre mode de réalisation, non représenté, le diamètre de l'arcade, et donc celui des segments, est variable le long de l'axe de révolution X, par exemple en diminuant de l'extrémité amont 1a vers l'extrémité aval 1b, à la manière d'un entonnoir.In another embodiment, not shown, the diameter of the yoke, and therefore that of the segments, is variable along the axis of revolution X, for example by decreasing from the upstream end 1a towards the downstream end 1b, like a funnel.

L'inclinaison α entre les parois amont et aval de chaque segment 11, 12 est déterminée en fonction, notamment des dimensions du manchon, de l'épaisseur de sa paroi en particulier et de la nature du matériau utilisé pour sa réalisation. De préférence, le manchon est réalisé avec une matière plastique polymère telle qu'une polyoléfine.The inclination α between the upstream and downstream walls of each segment 11, 12 is determined as a function, in particular of the dimensions of the sleeve, of the thickness of its wall in particular and of the nature of the material used for its production. Preferably, the sleeve is made with a polymeric plastic material such as a polyolefin.

Cette inclinaison α est généralement comprise entre 30° et 90°, lorsque le manchon 1 est dans la position dépliée de la figure 1a.This inclination α is generally between 30 ° and 90 °, when the sleeve 1 is in the unfolded position of FIG. 1a.

L'arcade torique 10 est tangente à la paroi aval 11b, 12b pour la rigidifier.The toric arch 10 is tangent to the downstream wall 11b, 12b to stiffen it.

En revanche, l'arcade 10 décrit un quart de méridien m vers l'amont, avant de se raccorder à la paroi amont 11a, 12a en définissant ainsi une ligne d'inflexion périphérique i qui forme une première articulation pour ladite paroi.However, the arch 10 describes a quarter of the meridian m upstream, before connecting to the upstream wall 11a, 12a by defining thus a peripheral inflection line i which forms a first articulation for said wall.

Les segments 11, 12, 13 sont séparés par des gorges périphériques g qui facilitent l'escamotage de la paroi amont 11a, 12a et augmentent la liberté en flexion du manchon 1.The segments 11, 12, 13 are separated by peripheral grooves g which facilitate the retraction of the upstream wall 11a, 12a and increase the freedom in bending of the sleeve 1.

Les gorges g ont, ici, une section en U mais elles peuvent, selon une variante non représentée, avoir une section en V.The grooves g have, here, a U-shaped section but they can, according to a variant not shown, have a V-shaped section.

La figure 2b représente une vue partielle en coupe du manchon 1 de la figure 2a dans la position de la figure 1c.Figure 2b shows a partial sectional view of the sleeve 1 of Figure 2a in the position of Figure 1c.

Dans cette position, le manchon 1 est fléchi de façon à orienter le col 2 selon l'axe Y faisant un angle β avec l'axe X de révolution.In this position, the sleeve 1 is bent so as to orient the neck 2 along the axis Y making an angle β with the axis X of revolution.

L'extrados du manchon 1 est alors en extension tandis que son intrados est comprimé.The upper surface of the sleeve 1 is then extended while its lower surface is compressed.

La flexion maximum est obtenue quand toutes les parois amont 11a, 12a, 13a des segments sont escamotées sur l'intrados du manchon 1.Maximum bending is obtained when all the upstream walls 11a, 12a, 13a of the segments are retracted on the lower surface of the sleeve 1.

Au cours de la phase d'escamotage, les parois amont 11a, 12a, 13a, subissent à la fois une déformation élastique et un pivotement vers l'aval sur une partie de leur pourtour. Ce pivotement s'effectue, d'une part, autour de l'axe de la première articulation qui est tangent à la ligne d'inflexion i et, d'autre part, autour d'un axe tangent au bord aval des gorges périphériques g, qui forme ainsi une seconde articulation.During the retraction phase, the upstream walls 11a, 12a, 13a, undergo both an elastic deformation and a pivoting downstream on a part of their periphery. This pivoting takes place, on the one hand, around the axis of the first articulation which is tangent to the line of inflection i and, on the other hand, around an axis tangent to the downstream edge of the peripheral grooves g , which thus forms a second joint.

En fin d'escamotage, les parois amont s'étendent de façon sensiblement parallèle aux parois aval 11b, 12b, 13b correspondantes qui n'ont subi aucune déformation, ni pivotement.At the end of retraction, the upstream walls extend substantially parallel to the corresponding downstream walls 11b, 12b, 13b which have not undergone any deformation or pivoting.

Le changement de géométrie, du manchon 1 de la position dépliée (figure 2a) à la position repliée (figure 2b), s'effectue donc au moyen d'une combinaison entre une déformation et un double pivotement des parois amont et en passant par un état transitoire instable de contraintes maximum qui provoque un déclic.The change in geometry, from the sleeve 1 from the unfolded position (FIG. 2a) to the folded position (FIG. 2b), is therefore carried out by means of a combination between a deformation and a double pivoting of the upstream walls and passing through a unstable transient state of maximum stress causing a click.

La figure 3 représente le manchon 1 en vue de dessus avec son extrémité aval 1b apparente. Dans ce mode de réalisation, les génératrices du manchon 1 définissent un cylindre de révolution d'axe X. La section de ce cylindre est constituée, ici, de deux demi-cercles réunis par des tronçons de droite tangents. De manière générale la surface extérieure ou enveloppe du manchon 1 est obtenue, en faisant glisser une ligne complexe située dans un plan et appelée génératrice, sur une ligne fermée, située dans un autre plan, et appelée directrice. Le point de contact est fixe sur la génératrice. Le plan de la directrice et le plan de la génératrice sont perpendiculaires et le plan de la génératrice contient constamment la normale à la directrice au point contact. La normale au plan de la directrice, au centre de celle-ci, est l'axe X du manchon. Si la directrice n'a pas de centre géométrique, l'axe du manchon n'est défini qu'en direction.FIG. 3 represents the sleeve 1 in top view with its downstream end 1b visible. In this embodiment, the generatrices of the sleeve 1 define a cylinder of revolution of axis X. The section of this cylinder consists, here, of two semicircles joined by tangent straight sections. In general, the outer surface or envelope of the sleeve 1 is obtained, by making drag a complex line located in one plane and called generator, onto a closed line, located in another plane, called director. The contact point is fixed on the generator. The plane of the director and the plane of the generator are perpendicular and the plane of the generator constantly contains the normal to the director at the contact point. The normal to the plane of the director, at the center of it, is the X axis of the sleeve. If the director has no geometric center, the axis of the sleeve is only defined in direction.

La paroi aval 13b du segment se prolonge à l'extrémité aval 1b par un col 2 fileté, délimitant un orifice d'évacuation 10b.The downstream wall 13b of the segment is extended at the downstream end 1b by a threaded neck 2, delimiting a discharge orifice 10b.

Selon un autre mode de réalisation, non représenté, les parois amont et aval sont tronconiques pour former des segments sensiblement annulaires d'axe X. Dans ce cas, la section du manchon 1 est circulaire.According to another embodiment, not shown, the upstream and downstream walls are frustoconical to form substantially annular segments of axis X. In this case, the section of the sleeve 1 is circular.

Les figures 4a et 4b représentent des vues de profil d'une application particulière du dispositif de transfert de l'invention.Figures 4a and 4b show side views of a particular application of the transfer device of the invention.

Dans cette application, le manchon 1 est monté sur la partie haute d'un récipient R.In this application, the sleeve 1 is mounted on the upper part of a container R.

Le manchon 1 peut être réalisé d'une seule pièce avec le récipient R ou fixé par vissage sur la partie haute dudit récipient autour d'un orifice d'évacuation.The sleeve 1 can be made in one piece with the container R or fixed by screwing on the upper part of said container around a discharge orifice.

Le manchon 1 est, en outre, pourvu d'un col 2 équipé d'un filetage sur lequel vient se visser un bouchon 3.The sleeve 1 is, moreover, provided with a neck 2 equipped with a thread onto which a plug 3 is screwed.
