Titre de l'invention : DISPOSITIF DE CONDITIONNEMENT ET DISTRIBUTION D'UN PRODUIT STERILE AVEC EMBOUTTitle of the invention: DEVICE FOR PACKAGING AND DISTRIBUTING A STERILE PRODUCT WITH TIP

DOSEUR ET CAPOT DOSER AND HOOD

Domaine technique Technical area

[0001] La présente invention se rapporte au domaine technique de l'emballage, et plus spé cialement à celui du conditionnement et de la distribution d'un produit liquide, semi- fluide ou visqueux destiné à être conservé stérilement, sans l'adjonction de conservateurs, et distribué par portions ou en doses, notamment en gouttes, à l’aide d’un ensemble distributeur. The present invention relates to the technical field of packaging, and more specifically to that of the packaging and distribution of a liquid, semi-fluid or viscous product intended to be kept sterile, without the addition of preservatives, and distributed in portions or in doses, in particular in drops, using a dispenser assembly.

[0002] L'invention a plus particulièrement pour objet un dispositif de conditionnement et distribution d'un produit, et qui comprend un récipient destiné à contenir le produit devant être distribué à l'aide d'un accessoire dont le récipient est muni, ledit accessoire comprenant un embout. The invention more particularly relates to a device for packaging and dispensing a product, and which comprises a container intended to contain the product to be dispensed using an accessory with which the container is provided, said accessory comprising a mouthpiece.

Technique antérieure Prior technique

[0003] On connaît des dispositifs de conditionnement de structure classique qui permettent de conserver et distribuer un produit sous forme de doses ou de gouttes calibrées ou sous toute autre forme, tout en maintenant sa propreté ou sa stérilité pendant toute la durée de son utilisation. [0003] Packaging devices of conventional structure are known which make it possible to preserve and distribute a product in the form of doses or calibrated drops or in any other form, while maintaining its cleanliness or its sterility throughout the duration of its use.

[0004] Ces dispositifs sont utilisés notamment dans les domaines pharmaceutique, cosmétique, et de l’alimentation, et pour certains plus particulièrement dans le domaine ophtalmologique. [0004] These devices are used in particular in the pharmaceutical, cosmetic and food fields, and for some more particularly in the ophthalmological field.

[0005] Un dispositif de ce type tel que décrit dans le brevet FR3080 844 permet d’obtenir un dosage précis. Il comprend un accessoire distributeur muni d’au moins une chambre de dosage qui, lorsqu’elle est sollicitée, permet de délivrer des doses de produit au travers d’un embout. Cet embout est composé de deux parties l’une rigide et l’autre souple, la partie souple élastique faisant pression sur la chambre de dosage délimitée par lesdites deux parties. Un ensemble de distribution du produit composé de l’extrémité élastique de la partie souple de l’embout en coopération avec l’extrémité de la partie rigide dudit embout permet au produit d’être expulsé vers l’extérieur lorsque la chambre est comprimée mais ne permet pas à l’air d’entrer à l’intérieur du récipient lorsque ladite chambre n’est plus sollicitée. [0005] A device of this type as described in patent FR3080 844 makes it possible to obtain an accurate dosage. It includes a dispenser accessory fitted with at least one dosing chamber which, when activated, makes it possible to deliver doses of product through a nozzle. This tip is made up of two parts, one rigid and the other flexible, the elastic flexible part putting pressure on the metering chamber delimited by said two parts. A product dispensing assembly composed of the elastic end of the flexible part of the nozzle in cooperation with the end of the rigid part of said nozzle allows the product to be expelled towards the outside when the chamber is compressed but does not does not allow air to enter inside the container when said chamber is no longer stressed.

[0006] Ce dispositif comprend un clapet antiretour qui permet l’alimentation de la chambre lorsque l’appui sur la partie souple cesse et qu’une dépression est créée dans la chambre par le retour élastique de ladite partie souple à sa position initiale. Ce clapet s’oppose au retour du produit dans le flacon lorsque la chambre est sollicitée. [0007] Ce dispositif prévoit de ménager un emplacement pour un filtre dont le but est de rendre stérile l’air entrant dans le flacon afin de compenser la dépression créée par la distribution d’une portion de produit ; ce filtre est placé dans la partie centrale rigide de l’embout. This device comprises a non-return valve which allows the supply of the chamber when pressing on the flexible part ceases and a vacuum is created in the chamber by the elastic return of said flexible part to its initial position. This valve opposes the return of the product into the bottle when the chamber is stressed. This device provides for a location for a filter whose purpose is to make sterile the air entering the bottle to compensate for the depression created by the distribution of a portion of product; this filter is placed in the rigid central part of the mouthpiece.

[0008] Ce brevet décrit également une valve associée au filtre et opérant de manière qu’elle puisse laisser entrer l’air dans le flacon et s’opposer à toute sortie d’air ou de liquide vers l’extérieur du flacon. [0008] This patent also describes a valve associated with the filter and operating in such a way that it can let air into the bottle and prevent any air or liquid from leaving the bottle.

[0009] Selon une variante décrite dans ce brevet l’air de remplacement entre dans le flacon par l’intermédiaire d’un conduit qui traverse axialement la partie centrale rigide de l’embout. [0009] According to a variant described in this patent, the replacement air enters the bottle via a duct which passes axially through the rigid central part of the tip.

[0010] Ce dispositif présente un inconvénient majeur commun à tous les dispositifs de ce genre qui est de ne pas assurer une propreté bactériologique parfaite à l'extérieur du récipient et plus particulièrement à l'extrémité de l'embout. This device has a major drawback common to all devices of this kind which is not to ensure perfect bacteriological cleanliness outside the container and more particularly at the end of the tip.

[0011] En effet, lorsqu'une goutte calibrée de produit a été expulsée par l'un des moyens que comportent ces dispositifs, conformément à leur destination, une fraction de cette goutte calibrée, appelée goutte résiduelle, subsiste à l'extrémité de l'embout. [0011] Indeed, when a calibrated drop of product has been expelled by one of the means of these devices, in accordance with their intended purpose, a fraction of this calibrated drop, called residual drop, remains at the end of the tip.

[0012] L'expérience a montré que, quel que soit le dispositif et le moyen mis en œuvre pour expulser une goutte calibrée de produit, il n'est pas possible d'éviter la formation d'une goutte résiduelle qui subsistera à l'extrémité de l'embout jusqu'à la prochaine utilisation du dispositif. [0012] Experience has shown that, whatever the device and the means used to expel a calibrated drop of product, it is not possible to avoid the formation of a residual drop which will remain after end of the tip until the next use of the device.

[0013] La formation puis la présence de cette goutte résiduelle présente un inconvénient majeur puisque, contrairement au produit qui se trouve à l'intérieur du récipient et qui peut être maintenu propre ou stérile, cette goutte résiduelle reste au contact de l'air extérieur qui est susceptible de la contaminer. [0013] The formation and then the presence of this residual drop presents a major drawback since, unlike the product which is inside the container and which can be kept clean or sterile, this residual drop remains in contact with the outside air. which is likely to contaminate it.

[0014] Le but recherché par ces dispositifs existants et qui est de maintenir propre ou stérile, sans l'aide de conservateurs, le produit qu'ils renferment et distribuent, n'est pas atteint puisque, si le produit est effectivement maintenu propre ou stérile à l'intérieur du récipient, il peut être contaminé à l'extrémité de l'embout distributeur. The aim sought by these existing devices and which is to keep clean or sterile, without the aid of preservatives, the product which they contain and distribute, is not achieved since, if the product is actually kept clean or sterile inside the container, it may be contaminated at the end of the dispensing tip.

[0015] Ainsi l’air de renouvellement admis dans le flacon par l’intermédiaire du conduit axial situé à l’intérieur de la partie rigide de l’embout entraînera la goutte résiduelle qui est présente à l’extrémité de l’embout et cette goutte résiduelle se trouvera en contact avec le filtre. [0015] Thus the renewal air admitted into the bottle via the axial duct located inside the rigid part of the tip will cause the residual drop which is present at the end of the tip and this residual drop will be in contact with the filter.

[0016] Ce filtre qui est destiné à laisser passer l’air et à stopper le passage des bactéries est de nature hydrophobe et n’est pas adapté au passage de la goutte résiduelle. La dé pression créée par le retour élastique de la chambre de dosage n’est pas suffisante pour permettre à la goutte résiduelle de traverser le filtre. [0016] This filter, which is intended to allow air to pass and to stop the passage of bacteria, is hydrophobic in nature and is not suitable for the passage of the residual drop. The pressure drop created by the elastic return of the dosing chamber is not sufficient to allow the residual drop to pass through the filter.

[0017] Après un certain nombre d’expulsion de doses et l’accumulation de gouttes ré siduelles le filtre se colmatera et s’opposera au passage de l’air de renouvellement ce qui aura pour effet de stopper le bon fonctionnement du dispositif. [0017] After a certain number of dose expulsions and the accumulation of residual drops, the filter will clog and will oppose the passage of renewal air. which will have the effect of stopping the proper functioning of the device.

[0018] Les brevets FR2941 682 et FR3 080843 proposent des dispositifs qui soufflent ou aspirent la goutte résiduelle dans un volume entourant l’accessoire distributeur et formant avec ce dernier un espace muni d’ouvertures dans lequel ladite goutte ré siduelle est destinée à sécher. [0018] Patents FR2941 682 and FR3 080843 propose devices which blow or suck the residual drop into a volume surrounding the dispenser accessory and forming with the latter a space provided with openings in which said residual drop is intended to dry.

[0019] L’inconvénient de ces dispositifs réside dans le fait que les gouttes résiduelles peuvent ne pas sécher si le produit distribué ne contient que peu ou pas de matières volatiles et s’accumuler dans l’espace dans lequel elles ont été envoyées risquant de souiller le dispositif avec du produit contaminé. [0019] The disadvantage of these devices lies in the fact that the residual drops may not dry if the product dispensed contains little or no volatile matter and accumulate in the space in which they were sent, risking soil the device with contaminated product.

[0020] On connaît également un dispositif tel que décrit dans le brevet FR3 080841 dans lequel un capot permet par un effet de pressurisation de faire pénétrer de l’air à l’intérieur du flacon et de faciliter ainsi l’amorçage du dispositif. Ce dispositif ne prévoit pas de traiter le problème de la goutte résiduelle qui peut ainsi contaminer l’extrémité de l’embout. There is also known a device as described in patent FR3 080841 in which a cover allows by a pressurization effect to allow air to penetrate inside the bottle and thus facilitate priming of the device. This device does not plan to deal with the problem of the residual drop which can thus contaminate the end of the tip.

[0021] Un dispositif permettant de ré-aspirer la goutte résiduelle à l’intérieur du flacon est décrit dans le brevet FR2 816600 qui est muni d’une membrane filtrante partiellement hydrophile et partiellement hydrophobe. Ce dispositif qui est actionné par appui sur les parois du flacon ne dispose pas de chambre de dosage et ne peut donc pas distribuer des doses calibrées de produit. Il est également soumis à la perméabilité des parois du flacon qui, pour être facilement actionnées, doivent être de faible épaisseur. A device making it possible to re-aspirate the residual drop inside the bottle is described in patent FR2 816600 which is provided with a partially hydrophilic and partially hydrophobic filtering membrane. This device, which is actuated by pressing on the walls of the bottle, does not have a metering chamber and therefore cannot dispense calibrated doses of product. It is also subject to the permeability of the walls of the bottle which, in order to be easily actuated, must be thin.

[0022] On connaît également des dispositifs tels que décrits dans le brevet FR 2 892397 qui comprennent un récipient rigide muni d'une poche souple rétractable qui contient le produit à distribuer à l'aide d'un accessoire de distribution. A chaque action sur l’accessoire de distribution une dose de produit est distribuée créant ainsi une dé pression à l'intérieur de la poche. Afin de compenser cette dépression la poche se rétracte afin de diminuer son volume. [0022] Devices are also known as described in patent FR 2 892397 which comprise a rigid container fitted with a retractable flexible pouch which contains the product to be dispensed using a dispensing accessory. With each action on the dispensing accessory, a dose of product is dispensed, thus creating a depression inside the pocket. In order to compensate for this depression, the pocket retracts in order to reduce its volume.

[0023] L’accessoire de distribution est composé d’un embout dont le récipient est muni, l'embout comportant au moins une partie souple dont la sollicitation permet de provoquer l'expulsion du produit, et un premier clapet associé à l'embout permettant au produit de sortir de l'ensemble composé par le récipient et l'embout lorsque ladite partie souple de l'embout est sollicitée, sans permettre à l'air extérieur d'entrer dans ledit embout lorsque ladite partie souple est relâchée, [0023] The dispensing accessory is composed of an endpiece with which the container is provided, the endpiece comprising at least one flexible part whose stress makes it possible to cause the expulsion of the product, and a first valve associated with the endpiece allowing the product to come out of the assembly made up of the container and the tip when said flexible part of the tip is stressed, without allowing outside air to enter said tip when said flexible part is released,

[0024] L’embout est muni d’une chambre de dosage. [0024] The tip is provided with a metering chamber.

[0025] Ce dispositif comprend un deuxième clapet antiretour qui permet l’alimentation de la chambre lorsque l’appui sur la partie souple cesse et qu’une dépression est créée dans la chambre par le retour élastique de ladite partie souple à sa position initiale. Ce clapet s’oppose au retour du produit dans la poche souple contenu dans le récipient lorsque la chambre est sollicitée. [0026] Un premier inconvénient majeur de ce type de dispositif réside dans la difficulté à remplir la chambre de dosage lorsque l’appui sur la partie souple cesse et qu’une dé pression est créée dans ladite chambre. En effet la force d’aspiration due au retour élastique de ladite partie souple à sa position initiale est faible et peut s’avérer in suffisante pour rétracter la poche et remplir correctement la chambre de dosage. This device comprises a second non-return valve which allows the supply of the chamber when pressing on the flexible part ceases and a depression is created in the chamber by the elastic return of said flexible part to its initial position. This valve opposes the return of the product into the flexible bag contained in the container when the chamber is stressed. [0026] A first major drawback of this type of device lies in the difficulty of filling the metering chamber when pressing on the flexible part ceases and a pressure drop is created in said chamber. In fact, the suction force due to the elastic return of said flexible part to its initial position is low and may prove to be insufficient to retract the bag and correctly fill the metering chamber.

[0027] Un deuxième inconvénient réside dans l’absence de moyen permettant de traiter la goutte résiduelle et de maintenir l’extrémité de l’embout propre. [0027] A second drawback resides in the absence of means making it possible to treat the residual drop and to keep the end of the tip clean.

[0028] La présente invention a pour but de permettre l'utilisation de dispositifs permettant de distribuer des gouttes calibrées de produit propre ou stérile, sans avoir l'inconvénient d'un risque de contamination bactérienne à l'extérieur dudit dispositif et de faciliter le renouvellement de l’air dans le récipient pendant toute la durée de l’utilisation du dispositif. The present invention aims to allow the use of devices for dispensing calibrated drops of clean or sterile product, without having the disadvantage of a risk of bacterial contamination outside of said device and to facilitate the renewal of the air in the container for the duration of the use of the device.

[0029] Plus généralement, l'invention a pour but de remédier aux inconvénients des dis positifs analogues de l'état de la technique et de proposer un tel dispositif qui convienne mieux aux diverses exigences de la pratique que les dispositifs connus.[0029] More generally, the object of the invention is to remedy the drawbacks of similar positive devices of the state of the art and to propose such a device which is better suited to the various requirements of practice than the known devices.

RÉSUMÉ ABSTRACT

[0030] En vue d’améliorer la situation, il est proposé selon l'invention un dispositif de condi tionnement et distribution d'un produit généralement liquide, semi-fluide ou visqueux, comprenant : [0030] In order to improve the situation, the invention proposes a device for packaging and dispensing a generally liquid, semi-fluid or viscous product, comprising:

- un récipient destiné à contenir le produit à conditionner et distribuer ; - a container intended to contain the product to be packaged and distributed;

- un accessoire distributeur comportant un embout muni d’une partie souple et d’une partie rigide permettant de délivrer une goutte ou dose de produit, au moins une chambre de dosage étant prévue dans l’embout, l’embout présentant une extrémité de distribution ; - a dispensing accessory comprising a tip provided with a flexible part and a rigid part making it possible to deliver a drop or dose of product, at least one dosing chamber being provided in the tip, the tip having a dispensing end ;

- un clapet antiretour permettant un accès à l’au moins une chambre de dosage pour du produit contenu dans le récipient ; - a non-return valve allowing access to the at least one metering chamber for the product contained in the container;

- un ensemble de renouvellement de l’air entrant dans le récipient après la délivrance de la goutte ou dose de produit ; - a set for renewing the air entering the container after delivery of the drop or dose of product;

- un conduit de communication avec un volume intérieur du récipient, au moins une partie du conduit étant disposé le long d’un axe longitudinal de la partie rigide de l’embout et associé à une valve anti-retour ; - a conduit communicating with an interior volume of the container, at least part of the conduit being arranged along a longitudinal axis of the rigid part of the endpiece and associated with a non-return valve;

- un capot conçu et agencé pour envelopper de façon étanche un espace de volume variable situé entre ledit capot et l’accessoire distributeur, en recouvrant une entrée du conduit qui débouche dans cet espace, - a cover designed and arranged to tightly envelop a space of variable volume located between said cover and the dispenser accessory, covering an inlet of the duct which opens into this space,

- avec la particularité que l’embout est actionnable par la partie souple pour permettre au produit d’être expulsé vers l’extérieur du dispositif via une sortie de produit formée dans l’extrémité de distribution lorsque ladite au moins une chambre remplie de produit est comprimée, sans permettre à l’air d’entrer à l’intérieur du récipient via ladite sortie de produit lorsque ladite au moins une chambre n’est plus sollicitée, le clapet antiretour permettant au produit de pénétrer dans ladite au moins une chambre lorsqu’elle n’est plus sollicitée mais s’opposant au retour du produit dans le récipient lorsque ladite au moins une chambre est sollicitée, et se caractérisant en ce que : l’entrée du conduit, située dans l’extrémité de distribution, débouche à l’extérieur de l’embout à proximité de ladite sortie de produit, le capot étant configuré, lors d’une mise en place du capot sur l’embout permettant de recouvrir ladite sortie de produit et l’entrée du conduit, pour générer une surpression dans le conduit via l’entrée, le conduit appartenant audit ensemble de renouvellement de l’air, ce grâce à quoi une goutte résiduelle présente à l’extrémité de distribution après ladite délivrance peut être entraînée, par l’effet de surpression combiné au flux entrant d’air de renouvellement, à l’intérieur du conduit. - with the particularity that the tip is actuated by the flexible part to allow the product to be expelled out of the device via a product outlet formed in the dispensing end when said at least one chamber filled with product is compressed, without allowing air to enter the interior of the container via said product outlet when said at least one chamber is no longer stressed, the non-return valve allowing the product to enter said at least one chamber when it is no longer stressed but opposing the return of the product into the container when said at least one chamber is stressed, and characterized in that: the inlet of the duct, located in the dispensing end, opens outside the endpiece close to the said product outlet, the cap being configured , when the cover is put in place on the endpiece making it possible to cover said product outlet and the inlet of the duct, to generate an overpressure in the duct via the inlet, the duct belonging to said set of renewal of the air, whereby a residual drop present at the dispensing end after said delivery can be driven, by the overpressure effect combined with the incoming flow of renewal air, inside the duct.

[0031] Ainsi le dispositif permet de distribuer des doses ou gouttes calibrées de produit propre ou stérile, typiquement par simples pressions sur l'embout dont l'accessoire est muni, tout en ayant l'assurance qu'aucune goutte résiduelle, susceptible d'être contaminée, ne subsistera à l'extrémité de l'embout après l'expulsion d'une dose ou goutte calibrée et que le renouvellement de l’air destiné à équilibrer la pression entre l’intérieur et l’extérieur du récipient est accentué par la fonction de surpression créée par le capot. [0031] Thus the device makes it possible to distribute doses or calibrated drops of clean or sterile product, typically by simple pressure on the tip with which the accessory is provided, while having the assurance that no residual drop, likely to be contaminated, will not remain at the end of the nozzle after the expulsion of a calibrated dose or drop and that the renewal of the air intended to balance the pressure between the inside and the outside of the container is accentuated by the overpressure function created by the cover.

[0032] Dans divers modes de réalisation selon l’invention, on peut avoir recours en outre à une ou plusieurs des dispositions suivantes : In various embodiments according to the invention, one can also use one or more of the following provisions:

[0033] Un espace interne au capot peut être soumis à l’effet de surpression, en utilisant par exemple une portée cylindrique sur laquelle coulisse ledit capot lorsqu’il est retiré ou remis en place. Le conduit débouche dans cet espace. [0033] A space inside the cover can be subjected to the overpressure effect, for example by using a cylindrical bearing surface on which said cover slides when it is removed or put back in place. The duct opens into this space.

Le capot comporte une partie cylindrique coopérant de façon étanche avec une partie cylindrique de l’embout rigide et permettant de réduire le volume de l’espace lorsque le capot est sollicité verticalement suivant l’axe longitudinal du dispositif entre une première position dans laquelle l’extrémité de la partie cylindrique du capot est en contact avec l’extrémité de la partie cylindrique de l’embout rigide et une deuxième position dans laquelle la partie cylindrique du capot recouvre entièrement la partie cy lindrique de la partie rigide de l’embout. The cover comprises a cylindrical part cooperating in a leaktight manner with a cylindrical part of the rigid endpiece and making it possible to reduce the volume of the space when the cover is loaded vertically along the longitudinal axis of the device between a first position in which the end of the cylindrical part of the cover is in contact with the end of the cylindrical part of the rigid end piece and a second position in which the cylindrical part of the cover completely covers the cylindrical part of the rigid part of the end piece.

[0034] Le conduit peut déboucher axialement (suivant la direction d’un axe longitudinal du dispositif). The duct can emerge axially (in the direction of a longitudinal axis of the device).

[0035] Le capot est conçu et agencé pour envelopper de façon étanche un espace adjacent à un débouché externe du conduit, le capot étant mobile, de préférence suivant une direction axiale d’éloignement par rapport à un fond du dispositif, entre une première position de montage et une deuxième position dans laquelle le capot réduit la taille de l’espace de façon à créer une surpression dans le récipient, l’air dudit espace étant comprimé dans la deuxième position par l’effet d’enveloppement étanche du capot qui est maintenu lors du passage de la première position à la deuxième position. The cover is designed and arranged to tightly wrap a space adjacent to an external outlet of the duct, the cover being movable, preferably in an axial direction away from a bottom of the device, between a first position mounting and a second position in which the cover reduces the size of the space so as to create an overpressure in the container, the air of said space being compressed in the second position by the sealing effect of the cover which is maintained during passage from the first position to the second position.

[0036] Optionnellement, il est prévu un filtre situé entre l’extrémité intérieure au récipient du conduit d’acheminement de l’air de renouvellement et la valve antiretour. [0036] Optionally, there is provided a filter located between the inner end of the container of the duct for conveying the renewal air and the non-return valve.

[0037] Ce filtre peut avantageusement avoir des qualités telles qu’il s’oppose au passage des bactéries. Il peut être partiellement hydrophobe et partiellement hydrophile de manière à permettre le passage de l’air de renouvellement ainsi que celui de la goutte résiduelle de l’extérieur vers l’intérieur du récipient. This filter can advantageously have qualities such that it opposes the passage of bacteria. It can be partially hydrophobic and partially hydrophilic so as to allow the passage of renewal air as well as that of the residual drop from the outside to the inside of the container.

[0038] Dans une variante le récipient rigide est muni d'une poche souple rétractable qui contient le produit à distribuer à l'aide d'un accessoire de distribution. [0038] Alternatively, the rigid container is provided with a retractable flexible pouch which contains the product to be dispensed using a dispensing accessory.

[0039] L’accessoire de distribution comprend une partie rigide, une partie souple, au moins une chambre de dosage étant délimitée entre les deux parties. The dispensing accessory comprises a rigid part, a flexible part, at least one metering chamber being delimited between the two parts.

[0040] A chaque action sur l’accessoire de distribution une dose de produit est distribuée créant ainsi une dépression à l'intérieur de la poche. Afin de compenser cette dé pression la poche se rétracte afin de diminuer son volume. [0040] With each action on the dispensing accessory, a dose of product is dispensed, thus creating a vacuum inside the pocket. In order to compensate for this depressure, the pocket retracts in order to reduce its volume.

[0041] Un volume d’air de renouvellement est introduit dans le récipient afin de compenser la dépression créée dans le volume situé à l’extérieur de la poche. [0041] A renewal air volume is introduced into the container in order to compensate for the negative pressure created in the volume situated outside the pocket.

[0042] Selon une particularité la poche souple est rendue inséparable de l’ensemble formé par le col du récipient rigide et l’accessoire de distribution. [0042] According to one feature, the flexible bag is made inseparable from the assembly formed by the neck of the rigid container and the dispensing accessory.

[0043] Le volume intérieur du récipient rigide entoure latéralement la poche souple et s’étend entre un fond du récipient rigide et la poche souple, la poche étant de préférence entièrement logée à l’intérieur du récipient rigide. The interior volume of the rigid container laterally surrounds the flexible pouch and extends between a bottom of the rigid container and the flexible pouch, the pouch preferably being entirely housed inside the rigid container.

[0044] La partie rigide de l’accessoire de distribution est conçu et agencée, en association avec le col du récipient rigide, pour permettre à l’air de renouvellement de pénétrer dans l’espace situé entre le récipient rigide et la poche souple. The rigid part of the dispensing accessory is designed and arranged, in association with the neck of the rigid container, to allow renewal air to enter the space between the rigid container and the flexible bag.

[0045] Un espace interne au capot peut être soumis à l’effet de surpression, en utilisant par exemple une portée cylindrique sur laquelle coulisse ledit capot lorsqu’il est retiré ou remis en place. Le conduit débouche dans cet espace. [0045] A space inside the cover can be subjected to the overpressure effect, for example by using a cylindrical surface on which said cover slides when it is removed or put back in place. The duct opens into this space.

Le capot comporte une partie cylindrique coopérant de façon étanche avec une partie cylindrique du récipient et permettant de réduire le volume de l’espace lorsque le capot est sollicité verticalement suivant l’axe longitudinal du dispositif entre une première position dans laquelle l’extrémité de la partie cylindrique du capot est en contact avec l’extrémité de la partie cylindrique du récipient et une deuxième position dans laquelle la partie cylindrique du capot recouvre entièrement la partie cylindrique du récipient. The cover comprises a cylindrical part cooperating in a sealed manner with a cylindrical part of the container and making it possible to reduce the volume of the space when the cover is loaded vertically along the longitudinal axis of the device between a first position in which the end of the cylindrical part of the cover is in contact with the end of the cylindrical part of the container and a second position in which the cylindrical part of the cover entirely covers the cylindrical part of the container.

[0046] Le conduit peut déboucher axialement (suivant la direction d’un axe longitudinal du dispositif). The duct can emerge axially (in the direction of a longitudinal axis of the device).

[0047] Le capot est conçu et agencé pour envelopper de façon étanche un espace adjacent à un débouché externe du conduit, le capot étant mobile, de préférence suivant une direction axiale d’éloignement par rapport à un fond du dispositif, entre une première position de montage et une deuxième position dans laquelle le capot réduit la taille de l’espace de façon à créer une surpression dans le récipient, l’air dudit espace étant comprimé dans la deuxième position par l’effet d’enveloppement étanche du capot qui est maintenu lors du passage de la première position à la deuxième position. [0047] The cover is designed and arranged to tightly envelop a space adjacent to an external outlet of the duct, the cover being movable, preferably along a axial direction of distance from a bottom of the device, between a first mounting position and a second position in which the cover reduces the size of the space so as to create an overpressure in the container, the air of said space being compressed in the second position by the sealing effect of the cover which is maintained during passage from the first position to the second position.

DESCRIPTION DE MODES DE REALISATION PREFERES DE L’INVENTION DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0052] Le dispositif tel que représenté sur la [Fig.l] fonctionne de la manière suivante : The device as shown in [Fig.l] operates as follows:

[0053] Dans une première phase l’utilisateur a sollicité la partie souple de l’embout 3 par appui sur les chambres de dosage 6 qui ont ainsi été comprimées suivant les flèches A, A’. [0053] In a first phase, the user applied the flexible part of the tip 3 by pressing on the metering chambers 6 which were thus compressed along the arrows A, A'.

[0054] L’extrémité 8 de la partie souple 3 en coopération avec l’extrémité correspondante de la partie rigide 7 a permis la distribution d’une goutte 12 de produit 2 suivant la flèche F et une goutte résiduelle 13 s’est formée à l’extrémité de distribution 22. The end 8 of the flexible part 3 in cooperation with the corresponding end of the rigid part 7 has allowed the distribution of a drop 12 of product 2 along the arrow F and a residual drop 13 has formed at the distribution end 22.

[0055] Dans une seconde phase l’utilisateur a cessé son appui sur la partie souple de l’embout 3 et les chambres de dosage 6 ont repris leur position initiale par retour élastique suivant les flèches B, B’. In a second phase, the user has stopped pressing on the flexible part of the endpiece 3 and the metering chambers 6 have resumed their initial position by elastic return following the arrows B, B′.

[0056] Ce retour élastique de la partie souple de l’embout 3 a créé une aspiration dans les chambres de dosage 6. [0056] This elastic return of the flexible part of the tip 3 created a suction in the metering chambers 6.

[0057] Sous l’effet de cette aspiration le produit 2 a traversé l’orifice 11 suivant la flèche C, soulevé le clapet antiretour 10 et pénétré dans les chambres de dosage 6 qui se trouvent ainsi remplies de produit 2. Under the effect of this suction, the product 2 has passed through the orifice 11 along the arrow C, lifted the non-return valve 10 and entered the metering chambers 6 which are thus filled with product 2.

[0058] Le remplissage du produit 2 dans les chambres de dosage 6 a créé une diminution du volume du produit 2 contenu dans le récipient 1 et une augmentation correspondante du volume libre 19 dans lequel est créée une dépression. The filling of the product 2 in the metering chambers 6 has created a reduction in the volume of the product 2 contained in the container 1 and a corresponding increase in the free volume 19 in which a depression is created.

[0059] Afin de compenser cette dépression un volume équivalent d’air de renouvellement pénètre de l’extérieur vers l’intérieur du dispositif par l’intermédiaire du conduit 9 situé dans l’axe longitudinal de la partie rigide 7 de l’embout suivant la flèche D, puis au travers de l’ensemble composé du filtre 4 et du clapet antiretour 5. In order to compensate for this depression, an equivalent volume of renewal air penetrates from the outside to the inside of the device via the conduit 9 located in the longitudinal axis of the rigid part 7 of the following nozzle arrow D, then through the assembly made up of the filter 4 and the non-return valve 5.

[0060] L’arrivée de cet air de renouvellement au travers du conduit 9 a pour conséquence d’aspirer la goutte résiduelle 13 à l’intérieur du dispositif. [0060] The arrival of this renewal air through the duct 9 results in to suck up the residual drop 13 inside the device.

[0061] La force d’aspiration créée par le retour élastique de la partie souple 3 de l’embout est cependant faible et ne permet pas à la goutte résiduelle de traverser le filtre 4. [0061] The suction force created by the elastic return of the flexible part 3 of the tip is however low and does not allow the residual drop to pass through the filter 4.

[0062] Sans action complémentaire et après la délivrance d’un certain nombre de gouttes 12 l’accumulation des gouttes résiduelles 13 sur la surface du filtre 4 aurait pour conséquence un colmatage dudit filtre 4 et un blocage du fonctionnement du dispositif par défaut d’arrivée de l’air de compensation et d’équilibrage des pressions entre l’intérieur et l’extérieur du récipient 1. [0062] Without additional action and after the delivery of a certain number of drops 12, the accumulation of residual drops 13 on the surface of the filter 4 would result in clogging of said filter 4 and blocking of the operation of the device by default of air supply for compensation and pressure equalization between the inside and the outside of container 1.

[0063] La [Fig.2] montre le dispositif représenté sur la [Fig.l] lorsque le capot 14 a été remis en place. [0063] The [Fig.2] shows the device shown in [Fig.l] when the cover 14 has been replaced.

[0064] Ledit capot 14 a coulissé verticalement suivant un axe longitudinal du dispositif suivant la flèche E. [0064] Said cover 14 has slid vertically along a longitudinal axis of the device along arrow E.

[0065] On peut noter que lors de cette remise en place du capot 14 après une première uti lisation dans une position intermédiaire seulement l’extrémité annulaire de la jupe 16 du capot 14 vient au contact étanche de la partie cylindrique 17 de l’embout rigide 7 délimitant ainsi un espace 15 clos. It may be noted that during this replacement of the cover 14 after a first use in an intermediate position only the annular end of the skirt 16 of the cover 14 comes into leaktight contact with the cylindrical part 17 of the end piece. rigid 7 thus delimiting a closed space 15 .

[0066] Après enfoncement complet du capot 14 la partie cylindrique 16 formant la jupe du capot 14 a une position de recouvrement maximal de la partie cylindrique 17 de l’embout rigide 7, le volume de l’espace 15 a ainsi diminué et une surpression est créée qui a pour effet d’introduire de l’air dans le récipient 1 suivant la flèche D. [0066] After complete depression of the cover 14, the cylindrical part 16 forming the skirt of the cover 14 has a position of maximum covering of the cylindrical part 17 of the rigid end piece 7, the volume of the space 15 has thus decreased and an overpressure is created which has the effect of introducing air into the container 1 along the arrow D.

[0067] Cette entrée d’air due à la surpression a pour effet d’entraîner la goutte résiduelle 13 au travers de l’ensemble composé du filtre 4 et de la valve antiretour 5 jusqu’à l’intérieur du récipient 1. This air inlet due to the overpressure has the effect of dragging the residual drop 13 through the assembly consisting of the filter 4 and the non-return valve 5 to the inside of the container 1.

[0068] On a ainsi réintroduit la goutte résiduelle 13 à l’intérieur du récipient 1 plus fa cilement que sous le seul effet d’aspiration dû au retour élastique de la partie souple de l’embout 3. The residual drop 13 has thus been reintroduced inside the container 1 more easily than under the suction effect alone due to the elastic return of the flexible part of the tip 3.

[0069] Il est à noter que la réintroduction de la goutte résiduelle 13 à l’intérieur du récipient 1 ne s’accompagne pas d’une contamination du produit 2 par ladite goutte résiduelle 13 puisque celle-ci a traversé le filtre 4 et a ainsi été débarrassée des bactéries qu’ éventuellement elle contenait. It should be noted that the reintroduction of the residual drop 13 inside the container 1 is not accompanied by contamination of the product 2 by said residual drop 13 since the latter has passed through the filter 4 and has thus been rid of the bacteria that it possibly contained.

[0070] On peut noter qu’il est possible de régler la valeur de la surpression créée par le dé placement du capot 14 en ajustant la longueur de recouvrement entre l’extrémité interne de la jupe 16 du capot 14 et la partie cylindrique 17 de l’embout rigide 7 afin d’obtenir un fonctionnement optimal du dispositif. It may be noted that it is possible to adjust the value of the overpressure created by the displacement of the cover 14 by adjusting the length of overlap between the inner end of the skirt 16 of the cover 14 and the cylindrical part 17 of the rigid end piece 7 in order to obtain optimum operation of the device.

[0071] Un premier but de l’invention a ainsi été atteint puisqu’ aucune goutte résiduelle de produit 2 ne subsiste à l’extrémité de l’embout 3 qui reste ainsi propre et ne risque pas de contaminer les gouttes 12 qui seront distribuées ultérieurement. A first object of the invention has thus been achieved since no residual drop of product 2 remains at the end of the tip 3 which thus remains clean and does not risk contaminating the drops 12 which will be distributed later. .

[0072] Un deuxième but de l’invention a également été atteint puisque le renouvellement de l’air dans le récipient 1 a été facilité. [0072] A second object of the invention has also been achieved since the renewal of the air in container 1 has been facilitated.

[0073] Tel que représenté sur la [Fig.3] le dispositif fonctionne de la manière suivante : [0073] As shown in [Fig.3] the device operates as follows:

[0074] L’utilisateur a actionné la partie souple de l’embout 3’, une goutte 12 (non re présentée) a été distribuée, une goutte résiduelle 13 s’est formée à l’extrémité de dis tribution 22, le produit 2 a été aspirée dans les chambres 6 à partir de la poche 21 lorsque l’utilisateur a relâché la pression sur la partie souple de l’embout 3’, la poche souple 21 s’est rétractée, le volume de l’espace 19 a augmenté créant ainsi un vide relatif ayant pour effet d’aspirer de l’air de renouvellement , la goutte résiduelle 13 a commencé à être aspirée à l’intérieur du dispositif, le capot 14 a été remis en place et après enfoncement complet la partie cylindrique 16’ formant la jupe dudit capot 14 a une position de recouvrement maximal de la partie cylindrique 17’ du récipient 1, le volume de l’espace 15 a ainsi diminué, une surpression a été créée qui a eu pour effet d’introduire de l’air supplémentaire à l’intérieur du conduit 9. The user has actuated the flexible part of the tip 3', a drop 12 (not shown) has been dispensed, a residual drop 13 has formed at the dispensing end 22, the product 2 was sucked into the chambers 6 from the pocket 21 when the user released the pressure on the flexible part of the tip 3', the flexible pocket 21 retracted, the volume of the space 19 increased thus creating a relative vacuum having the effect of sucking in renewal air, the residual drop 13 began to be sucked inside the device, the cover 14 was put back in place and after complete depression the cylindrical part 16 'forming the skirt of said cover 14 has a position of maximum overlap of the cylindrical part 17' of the container 1, the volume of the space 15 has thus decreased, an overpressure has been created which has had the effect of introducing additional air inside the duct 9.

[0075] La partie rigide de l’embout 3’ a été scindée en deux parties 7 et 7’ de manière à pouvoir acheminer l’air de renouvellement ainsi que l’air supplémentaire. [0075] The rigid part of the end piece 3′ has been split into two parts 7 and 7′ so as to be able to convey the renewal air as well as the additional air.

[0076] Un conduit 9’ perpendiculaire au conduit 9 a été créé dans la partie 7 de l’embout rigide et en continuation dans la partie rigide 7’. [0076] A conduit 9′ perpendicular to conduit 9 has been created in part 7 of the rigid end piece and in continuation in rigid part 7′.

[0077] Une étanchéité a été créée entre le pourtour de la partie rigide 7’ et l’intérieur du col du récipient rigide, un orifice de passage 18 a été créé et un passage 20 a été ménagé dans le col du récipient rigide 1 afin de permettre l’acheminement de l’air de renou vellement et de l’air supplémentaire vers l’espace 19. A seal has been created between the periphery of the rigid part 7' and the inside of the neck of the rigid container, a passage orifice 18 has been created and a passage 20 has been made in the neck of the rigid container 1 in order to to allow the delivery of renewal air and additional air to space 19.

[0078] L’air de renouvellement et l’air supplémentaire ont ainsi été admis dans l’espace 19 situé entre le récipient rigide 1 et la poche 21 après avoir traversé les conduits 9 et 9’ puis l’orifice 18 coopérant avec la valve antiretour 5’, puis soulevé ladite valve an tiretour 5’ et traversé le passage 20. The renewal air and the additional air have thus been admitted into the space 19 located between the rigid container 1 and the pocket 21 after having passed through the ducts 9 and 9' then the orifice 18 cooperating with the valve non-return 5', then lifted said valve year tiretour 5' and crossed the passage 20.

[0079] La surpression créée par la remise en place du capot 14 dans le volume 15 et l’arrivée de l’air supplémentaire ainsi obtenue a eu pour effet d’entraîner la goutte résiduelle 13 dans l’espace 19 situé entre le récipient rigide 1 et la poche 21 après avoir traversé les conduits 9 et 9’, l’orifice 18 coopérant avec la valve antiretour 5’, soulevé ladite valve antiretour 5’ puis traversé le passage 20, alors que cette dernière n’aurait pas pu suivre ce cheminement et notamment ouvrir la valve antiretour 5’ sous le seul effet de l’aspiration due au retour élastique de la partie souple de l’embout 3’. The overpressure created by the replacement of the cover 14 in the volume 15 and the arrival of the additional air thus obtained had the effect of driving the residual drop 13 into the space 19 located between the rigid container 1 and the pocket 21 after having passed through the ducts 9 and 9', the orifice 18 cooperating with the non-return valve 5', raised the said non-return valve 5' then crossed the passage 20, whereas the latter could not have followed this path and in particular open the non-return valve 5' under the sole effect of the suction due to the elastic return of the flexible part of the end piece 3'.

[0080] Un premier but de l’invention a ainsi été atteint puisqu’ aucune goutte résiduelle de produit 2 ne subsiste à l’extrémité de l’embout 3 qui reste ainsi propre et ne risque pas de contaminer les gouttes 12 qui seront distribuées ultérieurement. A first object of the invention has thus been achieved since no residual drop of product 2 remains at the end of the tip 3 which thus remains clean and does not risk contaminating the drops 12 which will be distributed later. .

[0081] Un deuxième but de l’invention a également été atteint puisque le renouvellement de l’air dans le récipient 1 a été facilité par une arrivée d’air supplémentaire. A second object of the invention has also been achieved since the renewal of the air in the container 1 has been facilitated by an additional air inlet.

[0082] On peut noter qu’il est possible de régler la valeur de la surpression créée par le dé- placement du capot 14 en ajustant la longueur de recouvrement entre l’extrémité interne de la jupe 16’ du capot 14 et la partie externe 17’ du récipient rigide 1 afin d’obtenir un fonctionnement optimal du dispositif. [0082] It may be noted that it is possible to adjust the value of the overpressure created by the placement of the cover 14 by adjusting the length of overlap between the internal end of the skirt 16' of the cover 14 and the external part 17' of the rigid container 1 in order to obtain optimum operation of the device.

[0083] D'autres modes de réalisation sont possibles sans sortir du cadre de l'invention. Ainsi on peut utiliser un dispositif ne comportant qu’une chambre de dosage, ou une ou des chambres de dosage de forme quelconque ou ne comportant pas de filtre destiné à stériliser l’air entrant dans le récipient, Other embodiments are possible without departing from the scope of the invention. Thus, it is possible to use a device comprising only one metering chamber, or one or more metering chambers of any shape or not comprising a filter intended to sterilize the air entering the container,

[0084] De même le capot 9 peut être vissé sur une portion filetée du dispositif, dans une variante. [0084] Similarly, the cover 9 can be screwed onto a threaded portion of the device, in a variant.
