Abstract

A stoppering device to be secured to a container neck comprises a tubular spout (18) defining a passage opening (24), and a plug. The plug (12) has an outer tubular shell (42) sliding on the tubular spout (18), and a bottom (44) provided with a sealing skirt (52) and multiple distribution holes (54). The bottom (44) of the plug engages with the connecting wall of the tubular spout (18) in the plugging position, while preserving an annular retention space (60) between the bottom (44) of the plug and the tubular spout (18). The bottom (44) comprises radial ribs (56) which are in an alternating arrangement between the distribution holes (54), and constitute retention facets retaining the liquid held in the retention space by adhesion. The small volume of liquid which, during the plugging phase, would be prevented from flowing back into the container closed by the stoppering device, can remain in the annular retention space without any particular risk of abrupt ejection, said retention being promoted by the presence of multiple walls in the chamber, in particular the retention facets.

Description

BOUCHON A OBTURATEUR COULISSANT PRESENTANT PLUSIEURS TROUS DE  SLIDING SHUTTER CAP HAVING MULTIPLE HOLES
DISTRIBUTION  DISTRIBUTION
DOMAINE TECHNIQUE DE L'INVENTION TECHNICAL FIELD OF THE INVENTION
[0001] L'invention se rapporte à un bouchon en deux pièces au moins, comportant un obturateur coulissant en translation par rapport à une embase entre une position d'obturation et une position ouverte dans laquelle l'obturateur reste solidaire de l'embase et forme un verseur à plusieurs orifices. The invention relates to a cap in two pieces at least, comprising a shutter sliding in translation relative to a base between a closed position and an open position in which the shutter remains secured to the base and forms a pourer with several orifices.
ETAT DE LA TECHNIQUE ANTERIEURE STATE OF THE PRIOR ART
[0002] Les bouchons à fermeture par mouvement de coulissement sans séparation d'un obturateur par rapport à une embase tubulaire ont trouvé depuis longtemps la faveur des consommateurs, notamment pour satisfaire des besoins itinérants lorsqu'aucun verre n'est à disposition pour boire, l'obturateur étant conformé pour permettre une prise en bouche avec une ergonomie éprouvée garantissant une grande simplicité d'utilisation. Parmi ces bouchons, certains présentent une pluralité de trous de distribution au niveau de l'obturateur pris en bouche, pour permettre un écoulement en plusieurs jets, à la manière d'une douchette. Cette disposition particulière permet un mélange de liquide et d'air plus important que pour un écoulement par un trou unique, et assure ainsi pour certaines boissons un confort accru de consommation, qui se traduit par une sensation de fraîcheur et une exaltation des saveurs. Sliding closing caps without separation of a shutter relative to a tubular base have long found favor with consumers, especially to meet itinerant needs when no glass is available to drink, the shutter being shaped to allow a grip in the mouth with a proven ergonomics ensuring ease of use. Among these plugs, some have a plurality of dispensing holes at the shutter taken in the mouth, to allow a flow in several streams, in the manner of a shower. This particular arrangement allows a greater mixing of liquid and air than for a single hole flow, and thus ensures for some drinks increased comfort of consumption, which results in a feeling of freshness and an exaltation of flavors.
[0003] Les bouchons de ce type présentent toutefois un risque accru d'éclaboussure à la fermeture. En effet, pour obturer le dispositif de bouchage, le consommateur appuie sur l'obturateur, qui coulisse jusqu'à atteindre sa position d'obturation. Sur sa trajectoire, l'obturateur passe par une position intermédiaire transitoire d'accostage de l'embase, position à partir de laquelle un contact glissant étanche s'établit entre l'obturateur et l'embase jusqu'à la position finale d'obturation. Si au moment d'atteindre cette position d'accostage, du liquide se trouve encore dans la partie de l'obturateur située au-dessus de ce contact étanche, ce liquide piégé entre l'obturateur et le verseur se trouve dans la suite de la course d'obturation repoussé vers les trous de distribution par le mouvement relatif des pièces, le verseur tubulaire de l'embase agissant en quelque sorte comme un piston coulissant à l'intérieur de l'obturateur. Les trous de distribution forment à ce moment autant de buses d'accélération du liquide qui est éjecté vers l'extérieur. Ce risque, très pénalisant pour le consommateur qui peut se tacher avec le liquide éjecté, a été identifié dans le document WO201046566 qui propose de donner aux trous de distribution une forme évasée vers l'extérieur. Cette solution s'avère efficace lorsque l'épaisseur de la paroi de l'obturateur traversée par les trous, qui définit la longueur de ces trous, est suffisante. Un besoin subsiste toutefois dans certaines configurations, notamment lorsque la boisson contenue dans le récipient à une tension de surface élevée et tend à ne pas refluer rapidement vers le récipient dans la phase précédant immédiatement la fermeture. Caps of this type, however, have an increased risk of splashing on closing. Indeed, to seal the closure device, the consumer presses the shutter, which slides to reach its closed position. In its trajectory, the shutter passes through a transient intermediate position of docking of the base, position from which a sealed sliding contact is established between the shutter and the base to the final position shutter . If at the moment of reaching this docking position, liquid is still in the part of the shutter located above this sealed contact, this liquid trapped between the shutter and the pourer is in the continuation of the shutter stroke pushed back to the distribution holes by the relative movement of the parts, the tubular pourer of the base acting in a way as a piston sliding inside the shutter. The distribution holes form at this moment as many acceleration nozzles of the liquid which is ejected to the outside. This risk, very detrimental for the consumer who can stain with the liquid ejected, has been identified in WO201046566 which proposes to give the distribution holes an outwardly flared shape. This solution is effective when the thickness of the wall of the shutter through which the holes, which defines the length of these holes, is sufficient. However, a need remains in certain configurations, especially when the beverage contained in the container at a high surface tension and tends not to flow back quickly to the container in the phase immediately preceding closing.
[0004] Dans le document US 3,439,842 est par ailleurs décrit un bouchon en deux pièces du type précédent, constitué d'une embase comportant une paroi plane de laquelle fait saillie un verseur tubulaire formant un orifice de passage pour le liquide, et d'un obturateur enveloppant le verseur tubulaire. Cet obturateur comporte une coque tubulaire extérieure et un fond duquel fait saillie, en direction de l'embase, une jupe d'étanchéité venant s'insérer, dans une position d'obturation, dans le verseur tubulaire. Le fond de l'obturateur présente en outre une multiplicité de trous de distribution de faible section. Le verseur tubulaire de l'embase est pourvu quant à lui de picots entourant l'orifice de passage et destiner à venir, en position d'obturation, se placer dans les trous de distribution. La fermeture de l'obturateur peut être entravée par la présence des picots, si ces derniers ne sont pas situés correctement en face des trous de distribution. Le consommateur risque d'appuyer fortement sur l'obturateur pour obtenir sa fermeture tout en tournant l'obturateur pour chercher l'alignement des picots et des trous de distribution. A l'instant où cet alignement est obtenu, la fermeture s'opère d'autant plus rapidement que le consommateur appuie fortement sur l'obturateur. En fin de fermeture, la partie inférieure de la coque tubulaire extérieure de l'obturateur vient brutalement en butée sur toute sa circonférence contre une paroi plane de l'embase. Un consommateur non prévenu, notamment un enfant, risque alors de se pincer les doigts (voire les lèvres) entre l'obturateur et l'embase.. De plus, cette cinématique de fermeture est propice à des éjections de liquide par les trous de distribution. Ce risque d'éjection est encore accru par la forme des trous de distribution qui présentent une section qui se rétrécie dans le sens de l'écoulement, favorisant une accélération du liquide par effet Venturi. Les difficultés de fermetures évoquées ci-dessus ont leur corollaire durant l'assemblage, et conduisent à un taux de défaut et de rébus important si aucune précaution n'est prise pour présenter les pièces suivant un angle prédéterminé avant leur engagement. Outre les défauts d'assemblage constatés du fait de l'absence d'alignement entre obturateur et embase, on s'expose à ce que la surface de contact entre obturateur et embase, qui devient visible à l'ouverture, soit marquée par le contact. La conception du bouchon n'est pas non plus totalement satisfaisante du point de vue des chaînes de cotes, les surfaces de l'obturateur et de l'embase qui viennent en butée pour définir la position d'obturation étant relativement éloignées de celles définissant l'étanchéité. [0005] Dans le document DE 10 2004 055 338 est décrit un bouchon comportant un verseur tubulaire à fixer au col d'un récipient, le verseur étant pourvu d'un puits central avec lequel coopère un obturateur mobile en translation par rapport au verseur pour obturer ou libérer le passage formé par le puits central. L'obturateur est pourvu de trous d'écoulement répartis à sa périphérie pour, permettre, en position ouverte le passage du liquide depuis l'intérieur du récipient par le puits et les trous d'écoulement vers l'extérieur. Le verseur est pourvu sur sa périphérie de pattes faisant saillie radialement et axialement. Ces pattes constituent des butées de fin de course de l'obturateur en position fermée, un volume de rétention annulaire étant dans cette position préservé entre l'obturateur et le verseur. Ce volume est destiné à empêcher une éjection du liquide à la fermeture. Toutefois, on constate que le liquide piégé dans le volume de rétention, s'il ne s'échappe pas violemment lors de la fermeture, risque malgré tout de s'échapper tôt ou tard après la fermeture par les trous d'écoulement prévus sur l'obturateur. In US 3,439,842 is also described a two-piece plug of the above type, consisting of a base having a flat wall from which protrudes a tubular pourer forming a passage opening for the liquid, and a shutter enveloping the tubular spout. This shutter comprises an outer tubular shell and a bottom which projects, in the direction of the base, a sealing skirt which is inserted in a closed position into the tubular spout. The bottom of the shutter further has a multiplicity of distribution holes of small section. The tubular pourer of the base is provided with pins around the passage opening and intended to come, in the closed position, to be placed in the dispensing holes. Closing the shutter can be hampered by the presence of the pins, if they are not located correctly in front of the distribution holes. The consumer may press hard on the shutter to close the shutter while turning the shutter for alignment of pins and dispensing holes. At the moment when this alignment is obtained, the closing occurs all the more quickly as the consumer strongly presses on the shutter. At the end of closing, the lower part of the outer tubular shell of the shutter suddenly abuts on its entire circumference against a flat wall of the base. An uninformed consumer, especially a child, may then pinch his fingers (or lips) between the shutter and the base .. In addition, this closing kinematics is conducive to ejections of liquid through the distribution holes. This risk of ejection is further increased by the shape of the distribution holes which have a section which narrows in the direction of flow, promoting acceleration of the liquid by the Venturi effect. The difficulties of closures mentioned above have their corollary during assembly, and lead to a rate of defect and large rebus if no precaution is taken to present the parts at a predetermined angle before their engagement. In addition to the assembly defects noted due to the lack of alignment between shutter and base, it is exposed that the contact surface between the shutter and base, which becomes visible at the opening, is marked by the contact . The design of the cap is also not completely satisfactory from the point of view of the chains of dimensions, the surfaces of the shutter and the base which abut to define the closed position being relatively distant from those defining the sealing. DE 10 2004 055 338 discloses a cap comprising a tubular pourer to be fixed to the neck of a container, the pourer being provided with a central well with which cooperates a shutter movable in translation relative to the pourer for closing or releasing the passage formed by the central well. The shutter is provided with flow holes distributed at its periphery to allow, in the open position, the passage of the liquid from the inside of the container through the well and the outflow holes. The pourer is provided on its periphery with lugs projecting radially and axially. These tabs constitute end stops of the shutter in the closed position, an annular retention volume being in this position preserved between the shutter and the pourer. This volume is intended to prevent ejection of the liquid on closing. However, it is noted that the liquid trapped in the retention volume, if it does not escape violently during closure, may still escape sooner or later after closure by the flow holes provided on the 'shutter.
EXPOSE DE L'INVENTION SUMMARY OF THE INVENTION
[0006] L'invention vise à remédier à tout ou partie des inconvénients de l'état de la technique identifiés ci-dessus. [0007] Pour ce faire est proposé selon un premier aspect de l'invention un dispositif de bouchage à solidariser à un col de récipient destiné à un liquide, le dispositif de bouchage comportant : un verseur tubulaire définissant un axe de référence du dispositif et délimitant un orifice de passage ; et un obturateur mobile en translation par rapport au verseur tubulaire parallèlement à l'axe de référence entre une position d'obturation et une position de distribution, l'obturateur présentant une coque tubulaire extérieure enveloppant le verseur tubulaire et coulissant sur le verseur tubulaire ; et un fond s'étendant perpendiculairement à l'axe de référence, le fond étant pourvu d'une jupe d'étanchéité, et de plusieurs trous de distribution, la jupe d'étanchéité coopérant avec le verseur tubulaire en position d'obturation pour obturer l'orifice de passage, et libérant l'orifice de passage pour former plusieurs voies de passage depuis le récipient vers l'extérieur par l'orifice de passage et les trous de distribution lorsque l'obturateur passe de la position d'obturation à la position de distribution, le fond de l'obturateur venant en appui axial contre le verseur tubulaire en position d'obturation en préservant un volume annulaire de rétention entre le fond de l'obturateur et le verseur tubulaire, le volume annulaire communiquant avec l'extérieur par les trous de distribution, le fond présentant des nervures radiales disposées en alternance entre les trous de distribution et formant autant des facettes de rétention par adhérence du liquide emprisonné dans le volume de rétention. The invention aims to remedy all or part of the disadvantages of the state of the art identified above. To do this is proposed according to a first aspect of the invention a closure device to be secured to a container neck for a liquid, the closure device comprising: a tubular pourer defining a reference axis of the device and delimiting a passage opening; and a shutter movable in translation relative to the tubular spout parallel to the reference axis between a closed position and a dispensing position, the shutter having an outer tubular shell surrounding the tubular spout and sliding on the tubular spout; and a bottom extending perpendicular to the reference axis, the bottom being provided with a sealing skirt, and with several dispensing holes, the sealing skirt cooperating with the tubular pourer in the closed position to close off the passage opening, and releasing the passage opening to form a plurality of passageways from the container outwardly through the passage opening and the dispensing holes when the shutter passes from the closed position to the distribution position, the bottom of the shutter bearing axially against the tubular pourer in the closed position while preserving an annular retention volume between the bottom of the shutter and the tubular pourer, the annular volume communicating with the outside by the distribution holes, the bottom having radial ribs arranged alternately between the dispensing holes and forming as many retention facings by adhesion of the trapped liquid da ns the retention volume.
[0008] La butée de fin de course d'obturation étant réalisée dans un espace non accessible au consommateur, tout risque de pincement au niveau de la butée est écarté. Cet espace confiné n'étant pas non plus visible à l'ouverture, on ne dévoile pas en position de distribution de région marquée par le contact entre pièces. Le faible volume de liquide qui se trouverait, durant la phase d'obturation, empêché de refluer dans le récipient fermé par le dispositif de bouchage, peut rester dans le volume annulaire de rétention sans risque particulier d'éjection brutale. Les trous de distribution constituent certes des voies par lesquelles le liquide peut s'écouler, mais cet écoulement, s'il a lieu malgré la tension de surface et l'adhérence induite, se fera sans vitesse. The end stop closing stop being carried out in a space not accessible to the consumer, any risk of pinching at the stop is removed. This confined space is not visible at the opening, we do not reveal in the region distribution position marked by the contact between pieces. The small volume of liquid that would be, during the closing phase, prevented from backing into the container closed by the closure device, can remain in the annular retention volume without particular risk of sudden ejection. The distribution holes are certainly channels through which the liquid can flow, but this flow, if it occurs despite surface tension and induced adhesion, will be without speed.
[0009] Les nervures radiales augmentent les surfaces sur le liquide peut se fixer dans le volume annulaire de rétention, ce qui est particulièrement adaptée à une boisson sucrée ou contenant des tensioactifs augmentant l'adhésion aux surfaces. The radial ribs increase the surfaces on the liquid can be fixed in the annular retention volume, which is particularly suitable for a sweet drink or containing surfactants increasing adhesion to surfaces.
[0010] Selon un mode de réalisation, le verseur tubulaire comporte une paroi tubulaire extérieure de guidage sur laquelle coulisse l'obturateur entre les positions d'obturation et de distribution, une paroi tubulaire intérieure de passage délimitant l'orifice de passage et dans laquelle pénètre la jupe d'étanchéité pour obturer l'orifice de passage par contact annulaire avec la paroi intérieure de passage, et une paroi annulaire de raccordement s'étendant radialement de la paroi tubulaire extérieure de guidage à la paroi tubulaire intérieure de passage, les nervures constituant une butée venant en appui axial contre la paroi annulaire de raccordement. According to one embodiment, the tubular pourer comprises an outer tubular guide wall on which the shutter slides between the closed and dispensing positions, an inner tubular passage wall defining the passage opening and in which penetrates the sealing skirt to seal the annular contact passage opening with the inner passage wall, and an annular connecting wall extending radially from the outer tubular guide wall to the inner tubular passage wall, the ribs constituting a stop bearing axially against the annular connecting wall.
[0011] De préférence, les nervures ont une dimension axiale faible à proximité de l'axe de référence et augmentant lorsqu'on s'éloigne radialement de l'axe de référence. Preferably, the ribs have a small axial dimension near the reference axis and increasing when one moves away radially from the reference axis.
[0012] Pour un guidage satisfaisant de l'obturateur par rapport au verseur sur toute la course entre les position de distribution et d'obturation, on peut prévoir que la coque tubulaire extérieure de l'obturateur présente au moins un jonc annulaire de guidage faisant saillie radialement vers le verseur tubulaire et en contact glissant avec une surface cylindrique de guidage du verseur tubulaire entre les positions d'obturation et de distribution. For satisfactory guidance of the shutter relative to the pourer over the entire stroke between the dispensing position and shutter, it can be provided that the outer tubular shell of the shutter has at least one annular guide ring making protruding radially towards the tubular pourer and in sliding contact with a cylindrical guide surface of the tubular pourer between the closure and dispensing positions.
[0013] On peut également prévoir que le verseur tubulaire présente au moins un jonc annulaire de guidage faisant saillie radialement vers la coque tubulaire extérieure de l'obturateur et en contact glissant avec une surface cylindrique de guidage de la coque tubulaire extérieure de l'obturateur entre les positions d'obturation et de distribution. It can also be provided that the tubular pourer has at least one annular guide ring projecting radially towards the tubular shell exterior of the shutter and in sliding contact with a cylindrical surface for guiding the outer tubular shell of the shutter between the closed and dispensing positions.
[0014] Suivant un mode de réalisation préféré, le verseur tubulaire présente deux joncs annulaires de guidage situés axialement de part et d'autre du jonc annulaire de guidage de la coque tubulaire extérieure de l'obturateur. According to a preferred embodiment, the tubular pourer has two annular guide rings located axially on either side of the annular guide ring of the outer tubular shell of the shutter.
[0015] Pour éviter des chocs en fin de course d'obturation et diminuer encore les risques d'éclaboussure, on peut prévoir que le dispositif ne comporte pas de moyen d'encliquetage en position d'obturation. [0016] Pour minimiser l'accélération de l'obturateur en début de course d'obturation, et limiter ainsi encore davantage les risques d'éclaboussure, on peut prévoir que le dispositif ne comporte pas de moyen d'encliquetage en position de distribution. To avoid shocks at the end of the closing stroke and further reduce the risk of splashing, it can be provided that the device does not include snap means in the closed position. To minimize the acceleration of the shutter at the start of the closing stroke, and thus further limit the risk of splashing, it can be provided that the device does not include snap means in the dispensing position.
[0017] Suivant un mode de réalisation, les trous de distribution présentent chacun une plus petite section, la somme des plus petites sections des trous de distribution étant sensiblement égale, à 20% près, à une plus petite section de passage définie entre la jupe d'étanchéité de l'obturateur et le verseur tubulaire en position de distribution. On trouve ainsi un compromis entre un débit maximum pour la consommation et la recherche d'un faible volume de liquide prisonnier durant la phase d'obturation. Pour limiter encore davantage le volume de liquide prisonnier, on fera en sorte que la somme des plus petites sections des trous de distribution soit inférieure à la plus petite section de passage définie entre la jupe d'étanchéité de l'obturateur et le verseur tubulaire en position de distribution. According to one embodiment, the distribution holes each have a smaller section, the sum of the smaller sections of the distribution holes being substantially equal, within 20%, to a smaller passage section defined between the skirt sealing of the shutter and the tubular pourer in dispensing position. There is thus a compromise between a maximum flow rate for consumption and the search for a small volume of liquid trapped during the closing phase. To further limit the volume of trapped liquid, it will be ensured that the sum of the smaller sections of the dispensing holes is smaller than the smallest passage section defined between the sealing skirt of the shutter and the tubular pourer. distribution position.
[0018] Préférentiellement, l'obturateur est libre de tourner par rapport à au verseur autour de l'axe de référence aussi bien en position d'obturation qu'en position de distribution et dans toute position intermédiaire. Il n'y a donc pas d'indexation angulaire de l'obturateur par rapport au verseur, ce qui simplifie considérablement l'assemblage. [0019] Préférentiellement, le verseur tubulaire fait partie intégrante d'une embase présentant des reliefs de fixation au col de récipient. Preferably, the shutter is free to rotate relative to the pourer around the reference axis both in the closed position in the dispensing position and in any intermediate position. There is no angular indexing of the shutter relative to the pourer, which greatly simplifies the assembly. Preferably, the tubular pourer is an integral part of a base having attachment reliefs to the container neck.
[0020] Préférentiellement, la coque tubulaire extérieure comporte une butée de fin de course de distribution coopérant avec le verseur tubulaire pour empêcher l'obturateur de se séparer du verseur tubulaire. Tout risque d'absorption de l'obturateur par le consommateur est ainsi évité. Preferably, the outer tubular shell comprises a distribution limit stop cooperating with the tubular pourer to prevent the shutter from separating from the tubular pourer. Any risk of absorption of the shutter by the consumer is thus avoided.
[0021] Suivant un mode de réalisation préféré, l'obturateur comporte plusieurs trous de distribution répartis à la périphérie de la jupe. According to a preferred embodiment, the shutter has a plurality of distribution holes distributed at the periphery of the skirt.
[0022] Selon un autre aspect de l'invention, celle-ci a trait à un dispositif de bouchage à solidariser à un col de récipient destiné à contenir un liquide, le dispositif de bouchage comportant : un verseur tubulaire définissant un axe de référence du dispositif, le verseur comportant une paroi tubulaire extérieure de guidage, une paroi tubulaire intérieure de passage délimitant un orifice de passage, et une paroi annulaire de raccordement entre la paroi tubulaire extérieure de guidage et la paroi tubulaire intérieure de passage ; et un obturateur coulissant en translation sur la paroi tubulaire extérieure de guidage parallèlement à l'axe de référence entre une position d'obturation et une position de distribution, l'obturateur présentant - une coque tubulaire extérieure enveloppant le verseur tubulaire et coulissant sur le verseur tubulaire ; et un fond s'étendant perpendiculairement à l'axe de référence, le fond étant pourvu d'une jupe d'étanchéité et de plusieurs trous de distribution répartis à la périphérie de la jupe, la jupe d'étanchéité pénétrant dans paroi tubulaire intérieure de passage en position d'obturation pour obturer l'orifice de passage par contact annulaire avec la paroi intérieure de passage, et libérant l'orifice de passage pour former plusieurs voies de passage depuis le récipient vers l'extérieur par l'orifice de passage et les trous de distribution lorsque l'obturateur passe de la position d'obturation à la position de distribution, le fond de l'obturateur présentant des nervures radiales disposées en alternance entre les trous de distribution en constituant une butée axiale venant en appui axial contre la paroi de raccordement du verseur tubulaire en position d'obturation en préservant un volume annulaire de rétention entre le fond de l'obturateur et le verseur tubulaire, le volume de rétention communiquant avec l'extérieur par le ou les trous de distribution, les nervures formant des parois de rétention par adhésion du liquide emprisonné dans le volume de rétention. According to another aspect of the invention, it relates to a closure device to be secured to a container neck for containing a liquid, the closure device comprising: a tubular pourer defining a reference axis of the device, the pourer comprising an outer tubular guide wall, an inner tubular passage wall defining a through hole, and an annular connecting wall between the outer tubular guide wall and the inner tubular passage wall; and a shutter sliding in translation on the outer tubular guide wall parallel to the reference axis between a closed position and a dispensing position, the shutter having - an outer tubular shell surrounding the tubular pourer and sliding on the pourer tubular; and a bottom extending perpendicularly to the reference axis, the bottom being provided with a sealing skirt and a plurality of distribution holes distributed around the periphery of the skirt, the sealing skirt penetrating into the inner tubular wall of passage in the closed position to close the passage opening by annular contact with the inner passage wall, and releasing the passage opening to form several passageways from the container to the outside through the passage opening and the dispensing holes when the shutter passes from the closed position to the dispensing position, the bottom of the shutter having radial ribs arranged alternately between the distribution holes constituting an axial abutment bearing axially against the wall connecting the tubular pourer in the closed position by preserving an annular retention volume between the bottom of the shutter and the tubular pourer, the retention volume communicating with the outside through the distribution hole or holes, the ribs forming retention walls by adhesion of the liquid trapped in the retention volume.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATION For clarity, identical or similar elements are identified by identical reference signs throughout the figures. DETAILED DESCRIPTION OF AN EMBODIMENT
[0025] Le dispositif de bouchage représenté sur les figures est composé de deux pièces, à savoir une embase 10 à fixer sur le col d'un récipient (non représenté) et un obturateur 12. De manière optionnelle, il peut être prévu un capuchon de protection contre la poussière qui vient recouvrir au moins l'obturateur 12. Ce capuchon optionnel n'a pas été représenté ici, car il n'est pas utile à la compréhension de l'invention.  The closure device shown in the figures is composed of two parts, namely a base 10 to be fixed on the neck of a container (not shown) and a shutter 12. Optionally, it can be provided a cap dust cover that covers at least the shutter 12. This optional cap is not shown here, because it is not useful for understanding the invention.
[0026] L'embase 10, représenté en vue de côté sur la figure 4 et en coupe sur les figures 1 à 3, est composée d'une paroi cylindrique de fixation 14 présentant un filetage intérieur de fixation 16 au col de récipient, d'un verseur tubulaire 18 et d'une paroi de raccordement 20 entre le verseur tubulaire et la paroi cylindrique de fixation, cette paroi de raccordement étant ici étagée et présentant notamment une partie annulaire plane 22 permettant une réduction de diamètre entre la paroi cylindrique de fixation 14 et le verseur tubulaire 18. Le verseur tubulaire 18 se projette en saillie depuis cette partie plane annulaire 22 vers l'obturateur 12 et définit un axe géométrique de référence 100 du dispositif de bouchage. Le verseur tubulaire 12 forme un orifice de passage 24 pour un liquide, en pratique une boisson, depuis l'intérieur du récipient vers l'extérieur. Le verseur tubulaire 18 comporte une paroi tubulaire extérieure de guidage 26, une paroi tubulaire intérieure de passage 28 délimitant l'orifice de passage 24, et une paroi annulaire de raccordement 30 constituant un rebord de l'orifice de passage 24 et s'étendant radialement de la paroi tubulaire extérieure de guidage 26 à la paroi tubulaire intérieure de passage 28. La paroi extérieure de guidage 26 présente une section de guidage 32, ici cylindrique mais pouvant le cas échéant être légèrement tronconique ou profilée, s'étendant entre un jonc inférieur 34 proche de la partie annulaire plane 22 et un jonc supérieur 36 plus éloigné de la partie annulaire plane 22. L'embase peut également comporter une bague d'inviolabilité sécable 38 reliée à la paroi cylindrique de fixation 14 par des pontets sécables 40. The base 10, shown in side view in Figure 4 and in section in Figures 1 to 3, is composed of a cylindrical fixing wall 14 having an internal fixing thread 16 to the container neck, d a tubular pourer 18 and a connecting wall 20 between the tubular pourer and the cylindrical fixing wall, this connecting wall here being stepped and in particular having a flat annular portion 22 allowing a reduction in diameter between the cylindrical fixing wall 14 and the tubular pourer 18. The tubular pourer 18 projects projecting from this annular flat portion 22 towards the shutter 12 and defines a reference geometric axis 100 of the closure device. The tubular spout 12 forms a through hole 24 for a liquid, practically a beverage, from inside the container to the outside. The tubular pourer 18 has an outer tubular guide wall 26, an inner tubular passage wall 28 defining the through hole 24, and an annular connecting wall 30 constituting a rim of the passage opening 24 and extending radially. of the outer tubular guide wall 26 to the inner tubular passage wall 28. The outer guide wall 26 has a guide section 32, here cylindrical but possibly optionally slightly frustoconical or profiled, extending between a lower ring 34 near the planar annular portion 22 and an upper ring 36 further from the flat annular portion 22. The base may also comprise a breakable tamperproof ring 38 connected to the cylindrical fixing wall 14 by breakable bridges 40.
[0027] L'obturateur 12, représenté en détail sur les figures 5 et 6, recouvre le verseur tubulaire 18 et présente une coque tubulaire extérieure 42 enveloppant le verseur tubulaire 18 et un fond 44 s'étendant perpendiculairement à l'axe de référence. Comme représenté en particulier sur la figure 6, la face intérieure de la coque tubulaire extérieure 42 est pourvue d'un bourrelet annulaire de guidage 46 faisant saillie vers le verseur tubulaire 18 et venant au contact de la section de guidage 32 du verseur. Par ailleurs la coque tubulaire extérieure 42 présente sur sa face intérieure deux faces de guidage 48, 50 axialement de part et d'autre du bourrelet 46. Ces parois, ici cylindriques, sont en contact chacune avec l'un des joncs de guidage 34, 36 du verseur 18. L'obturateur 12 est ainsi mobile en translation parallèlement à l'axe de référence 100 et guidé dans ce mouvement par les deux joncs 34, 36 et le bourrelet 46 glissant sur les faces de guidage correspondantes 48, 50, 32 entre une position extrême de distribution représentée sur la figure 1, dans laquelle le bourrelet 46 est en butée axiale contre le jonc supérieur 36 et une position extrême d'obturation représentée sur la figure 3, en passant par une position intermédiaire représentée sur la figure 2. Le bourrelet46 et le jonc supérieur 36 sont conformés de façon à ce qu'il ne soit pas possible de séparer l'obturateur 12 du verseur 18 sans exercer une force considérable, bien supérieure à celle que pourrait exercer un consommateur dans des conditions normales d'utilisation. Les faces de guidage 48, 50, 32 sont toutes des surfaces de révolution autour de l'axe géométrique de référence 100, de sorte que de la position d'obturation à la position de distribution, l'obturateur soit libre de tourner par rapport au verseur autour de l'axe de référence. The shutter 12, shown in detail in Figures 5 and 6, covers the tubular spout 18 and has an outer tubular shell 42 surrounding the tubular spout 18 and a bottom 44 extending perpendicular to the axis of reference. As shown in particular in Figure 6, the inner face of the outer tubular shell 42 is provided with an annular guide bead 46 projecting towards the tubular spout 18 and coming into contact with the guide section 32 of the spout. Moreover, the outer tubular shell 42 has on its inner face two guide faces 48, 50 axially on either side of the bead 46. These walls, here cylindrical, are each in contact with one of the guide rods 34, 36 of the pourer 18. The shutter 12 is thus movable in translation parallel to the reference axis 100 and guided in this movement by the two rods 34, 36 and the bead 46 sliding on the corresponding guide faces 48, 50, 32 between an extreme dispensing position shown in Figure 1, wherein the bead 46 is in axial abutment against the upper ring 36 and a closed end position shown in Figure 3, through an intermediate position shown in Figure 2 The bead 46 and the upper ring 36 are shaped so that it is not possible to separate the shutter 12 of the pourer 18 without exerting a considerable force, much greater than that for exercise a consumer under normal conditions of use. The guide faces 48, 50, 32 are all surfaces of revolution about the reference geometric axis 100, so that from the closed position to the dispensing position, the shutter is free to rotate relative to the pourer around the reference axis.
[0028] Le fond 44 de l'obturateur est pourvu d'une jupe d'étanchéité 52 faisant saillie vers le verseur 18. Cette jupe d'étanchéité 52 présente une forme générale de révolution autour de l'axe de référence 100, et de préférence cylindrique ou légèrement tronconique évasée vers le verseur, pour pénétrer dans l'orifice de passage 24 et obturer celui-ci lorsque l'obturateur passe de la position de distribution de la figure 1 à la position d'obturation de la figure 3. Le fond 44 de l'obturateur présente par ailleurs plusieurs trous de distribution 54 répartis à la périphérie de la jupe d'étanchéité, la partie du fond couvrant la jupe d'étanchéité étant pleine. Les trous de distribution 54 peuvent être cylindriques, ou de préférence de forme évasée vers l'extérieur, à l'opposé du verseur 18. [0029] Le fond 44 de l'obturateur présente également des nervures radiales 56 faisant saillie depuis le fond et disposées entre les trous de distribution 54. Ces nervures 56 on une dimension axiale faible à proximité de l'axe géométrique de référence 100, et augmentant lorsqu'on s'éloigne de l'axe géométrique de référence 100. Le fond 44 présente par ailleurs, dans l'espace qui n'est pas occupé par les nervures 56 et en dehors des trous de distribution 54, une surface plane tournée vers le verseur 18 et perpendiculaire aux nervures 56. The bottom 44 of the shutter is provided with a sealing skirt 52 projecting towards the pourer 18. This sealing skirt 52 has a general shape of revolution about the reference axis 100, and of preferably cylindrical or slightly frustoconical flared towards the pourer, to enter the through hole 24 and close it when the shutter passes from the dispensing position of Figure 1 to the closed position of Figure 3. The The bottom 44 of the shutter also has a plurality of distribution holes 54 distributed around the periphery of the sealing skirt, the portion of the bottom covering the sealing skirt being full. The distribution holes 54 may be cylindrical, or preferably outwardly flared, opposite the pourer 18. The bottom 44 of the shutter also has radial ribs 56 projecting from the bottom and disposed between the distribution holes 54. These ribs 56 have a small axial dimension near the reference geometric axis 100, and increasing when one moves away from the reference geometric axis 100. The bottom 44 also has, in the space which is not occupied by the ribs 56 and outside the distribution holes 54, a plane surface turned towards the spout 18 and perpendicular to the ribs 56.
[0030] Le dispositif de bouchage fonctionne de la manière suivante. The closure device operates in the following manner.
[0031] Dans la position de distribution de la figure 1, la boisson peut s'écouler librement depuis l'intérieur du récipient vers l'extérieur par l'orifice de passage 24 et les trous de distribution 54 en formant des jets multiples. Suivant l'effet souhaité, la plus petite section des trous de distribution 54 doit être adaptée à la section efficace du passage délimité entre l'obturateur 18 et la jupe d'étanchéité 52. On entend ici par section efficace le produit de la plus petite distance entre la jupe d'étanchéité et l'obturateur en position de distribution par le périmètre correspondant mesuré à mi- distance entre la jupe d'étanchéité et l'obturateur. Dans une application où l'on ne souhaite pas que l'écoulement par les trous de distribution soit à grande vitesse, on fera en sorte que la somme des plus petites sections des trous de distribution soit supérieure à la section efficace du passage. Si au contraire on souhaite des jets puissants, on prévoira, pour des trous de distribution 54 de section donnée, une plus grande section efficace du passage entre obturateur et jupe d'étanchéité, donc une plus grande distance axiale entre la jupe d'étanchéité 52 et le verseur 18 en position de distribution. En choisissant des sections égales, ou proches à 10% ou 20% près, on obtient un équilibrage au passage entre l'obturateur et le verseur, la pression exercée sur le récipient conditionnant dans ce cas la vitesse d'éjection. In the dispensing position of Figure 1, the drink can flow freely from the inside of the container to the outside through the passage opening 24 and the distribution holes 54 by forming multiple jets. Depending on the desired effect, the smallest section of the distribution holes 54 must be adapted to the effective section of the passage delimited between the shutter 18 and the sealing skirt 52. Here, the cross-section is understood to mean the product of the smallest distance between the sealing skirt and the shutter in dispensing position by the corresponding perimeter measured at mid-distance between the sealing skirt and the shutter. In an application where it is not desired for the flow through the dispensing holes to be at a high speed, the sum of the smaller sections of the dispensing holes should be greater than the effective section of the passage. If, on the other hand, strong jets are desired, provision will be made, for distribution holes 54 of given section, for a larger cross-section of the passage between the shutter and the sealing skirt, and therefore a greater axial distance between the sealing skirt 52. and the pourer 18 in dispensing position. By choosing equal sections, or close to 10% or 20%, we obtain a balanced passage between the shutter and the pourer, the pressure exerted on the container conditioning in this case the ejection speed.
[0032] Pour obturer le dispositif de bouchage, le consommateur appuie sur l'obturateur 12, qui se met à coulisser jusqu'à atteindre la position d'obturation de la figure 3, en passant par la position intermédiaire de la figure 2. Cette position intermédiaire est ici intéressante à évoquer, car elle permet d'expliquer le problème susceptible d'être rencontré par le consommateur et résolu par l'invention. En règle générale, le récipient est orienté avec son col vers le haut au moment de l'obturation, de sorte que la boisson ne s'écoule pas vers l'extérieur et devrait au contraire refluer vers le récipient. La paroi de raccordement 30 et la paroi intérieure de passage 28 sont d'ailleurs conformées en entonnoir pour favoriser ce retour vers le récipient. Du liquide peut toutefois rester prisonnier entre l'obturateur 12 et le verseur 18, notamment si la tension interfaciale entre le liquide et les parois du dispositif de bouchage favorise une adhésion sur ces dernières. Cette faible quantité de liquide qui n'a pas reflué se retrouve prisonnière dès que le dispositif, lors de la phase d'obturation, atteint la position d'accostage de la figure 2, qui correspond au premier contact entre la jupe d'étanchéité 52 et le verseur 18 et à l'obstruction du passage de retour vers la bouteille, engendrant le volume de liquide prisonnier. To close the closure device, the consumer presses the shutter 12, which begins to slide to reach the closed position of Figure 3, through the intermediate position of Figure 2. This intermediate position is interesting here to discuss, because it helps to explain the problem likely to be met by the consumer and resolved by the invention. In good standing Generally, the container is oriented with its neck up at the time of filling, so that the drink does not flow outward and should instead flow back to the container. The connecting wall 30 and the inner passage wall 28 are also funnel-shaped to promote this return to the container. However, liquid may remain trapped between the shutter 12 and the pourer 18, especially if the interfacial tension between the liquid and the walls of the closure device promotes adhesion thereon. This small amount of liquid that has not refluxed is found trapped once the device, during the closing phase, reaches the docking position of Figure 2, which corresponds to the first contact between the sealing skirt 52 and the pourer 18 and the obstruction of the passage back to the bottle, generating the volume of liquid prisoner.
[0033] La position de la figure 2 n'est qu'une position transitoire et l'obturateur poursuit sa trajectoire jusqu'à ce que l'obturateur 12 vienne en butée contre le verseur 18 dans la position extrême de la figure 3. En l'occurrence, c'est le fond 44 de l'obturateur 12 qui vient en butée axiale contre le verseur 18, sans qu'il y ait contact entre la coque tubulaire extérieure 42 de l'obturateur et la paroi transversale 22 de l'embase. On peut ainsi dimensionner librement l'espacement que l'on souhaite conserver en position d'obturation entre la coque tubulaire extérieure 42 et la paroi transversale 22 de l'embase. Plus précisément, dans ce mode de réalisation, le contact est réalisé entre les nervures 56 du fond et la paroi de raccordement 30 du verseur, dans la partie des nervures 56 ayant la plus grande dimension axiale et située radialement à l'extérieur. The position of Figure 2 is a transient position and the shutter continues its trajectory until the shutter 12 comes into abutment against the pourer 18 in the extreme position of Figure 3. In the occurrence is the bottom 44 of the shutter 12 which abuts axially against the pourer 18, without there being contact between the outer tubular shell 42 of the shutter and the transverse wall 22 of the base. It is thus possible to freely dimension the spacing that it is desired to maintain in the closed position between the outer tubular shell 42 and the transverse wall 22 of the base. More specifically, in this embodiment, the contact is made between the ribs 56 of the bottom and the connecting wall 30 of the pourer, in the portion of the ribs 56 having the largest axial dimension and located radially outwardly.
[0034] Dans la position de la figure 3, les nervures 56 n'isolent pas complètement les uns des autres les trous de distribution 54. Au contraire, un volume de rétention 60 annulaire reliant entre eux les trous de distribution 54 est préservé. Ce volume de rétention 60 est plus important que le volume de liquide que l'on peut raisonnablement s'attendre à trouver piégé entre le verseur 18 et l'obturateur 12 au moment de l'obturation, dans des conditions normales d'obturation, c'est-à-dire avec l'axe géométrique de référence vertical ou faisant un angle de moins de 45° avec la verticale, le dispositif de bouchage étant au-dessus du col du récipient. Il n'y a donc pas d'effet de piston entre le verseur 18 et l'obturateur 12, et donc pas de risque d'éjection intempestive de liquide par les trous de distribution 54. In the position of Figure 3, the ribs 56 do not completely isolate the distribution holes 54. On the contrary, an annular retention volume 60 interconnecting the distribution holes 54 is preserved. This retention volume 60 is greater than the volume of liquid that can reasonably be expected to be trapped between the pourer 18 and the shutter 12 at the time of sealing, under normal sealing conditions, c that is to say with the vertical reference geometric axis or at an angle of less than 45 ° with the vertical, the closure device being above the neck of the container. So there is no piston effect between the pourer 18 and the shutter 12, and therefore no risk of inadvertent ejection of liquid through the distribution holes 54.
[0035] Les nervures 56 constituent des facettes sur lesquelles le liquide peut adhérer, de sorte que le faible volume de liquide emprisonné dans le volume de rétention ne risque pas de s'échapper par les trous de distribution 54. The ribs 56 are facets on which the liquid can adhere, so that the small volume of liquid trapped in the retention volume is not likely to escape through the distribution holes 54.
[0036] Il est à noter que pour limiter l'accélération initiale de l'obturateur 12 au début de la course d'obturation, c'est-à-dire au moment de quitter la position de la figure 1, on peut prévoir que cette position ne soit pas indexée axialement. En d'autres termes, on peut choisir de ne pas prévoir de gorge d'encliquetage élastique du bourrelet 46 ou du jonc supérieur 36 dans la position de distribution. It should be noted that to limit the initial acceleration of the shutter 12 at the beginning of the shutter stroke, that is to say at the moment of leaving the position of FIG. 1, it can be provided that this position is not indexed axially. In other words, one can choose not to provide an elastic snap groove of the bead 46 or the upper ring 36 in the dispensing position.
[0037] De même, pour limiter les chocs en fin de course d'obturation, on peut choisir de ne pas prévoir de gorge d'encliquetage élastique du bourrelet 46 ou du jonc inférieur 34 dans la position d'obturation de la figure 3. L'arrivée sans à-coup dans la position d'obturation permet de réduire encore les risques de décollement du liquide piégé sur les parois du volume de rétention 60, et notamment sur les parois des nervures 56. Similarly, to limit shocks at the end of the closing stroke, one can choose not to provide an elastic latching groove of the bead 46 or the lower ring 34 in the closed position of Figure 3. The arrival smoothly in the closed position further reduces the risks of detachment of the trapped liquid on the walls of the retention volume 60, and in particular on the walls of the ribs 56.
[0038] Naturellement, diverses variantes sont envisageables. Certaines des nervures peuvent être omises ou leur forme modifiée si la rétention du liquide par adhérence sur les parois des nervures n'est pas essentielle dans une application donnée, par exemple si la tension interfaciale entre la boisson considérée et les parois des nervures n'est pas suffisante pour un effet notable. Naturally, various variants are possible. Some of the ribs may be omitted or their shape modified if retention of the liquid by adhesion to the walls of the ribs is not essential in a given application, for example if the interfacial tension between the drink in question and the walls of the ribs is not enough for a noticeable effect.
[0039] Dans ce cas, la butée pourra être réalisée par un épaulement annulaire du fond, ou de préférence par des entretoises - c'est-à-dire des nervures de faible longueur radiale - réparties sur la circonférence du fond. On peut également envisager que la butée soit réalisée par une partie annulaire non saillante du fond faisant office de siège, sur lequel viennent en appui des nervures réalisées sur la paroi annulaire de raccordement du verseur. Quelle que soit la solution retenue, il faut tenir compte de la liberté de rotation de l'obturateur par rapport au verseur. Il faut également de manière préférentielle répartir le contact entre butée et siège de contrebutée sur la circonférence du dispositif, pour éviter un désaxage de l'obturateur par rapport au verseur. Il faut enfin de manière préférentielle limiter la quantité de matière utilisée. Pour répondre à l'ensemble de ces contraintes, et dans la mesure où une des surfaces de la butée, côté verseur ou côté obturateur, doit être en saillie vers l'autre pièce pour constituer le volume de rétention, on aura intérêt à prévoir que la partie en saillie soit constituée par des éléments individuels répartis sur la circonférence du dispositif, et venant en appui sur l'autre pièce contre un siège annulaire obtenu sans ajout de matière. In this case, the abutment may be performed by an annular shoulder of the bottom, or preferably by spacers - that is to say, ribs of short radial length - distributed on the circumference of the bottom. It is also conceivable that the stop is made by a non-projecting annular portion of the seat bottom, on which are supported ribs formed on the annular connecting wall of the pourer. Whichever solution is chosen, it is necessary to take into account the freedom of rotation of the shutter with respect to the pourer. It is also preferable to distribute the contact between the stop and the seat of against the circumference of the device, to avoid misalignment of the shutter relative to the pourer. Finally, it is preferable to limit the amount of material used. To meet all these constraints, and to the extent that one of the surfaces of the abutment, pouring side or shutter side, must be projecting towards the other part to form the retention volume, it will be advantageous to provide that the protruding portion is constituted by individual elements distributed over the circumference of the device, and bearing on the other part against an annular seat obtained without adding material.
[0040] L'embase et l'obturateur sont de préférence tous deux en matière plastique obtenus par moulage par injection. The base and the shutter are preferably both plastic obtained by injection molding.
