LANGUETTE RESSORT SPRING TONGUE
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. [0001] 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 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 et étant monté d'une manière étanche sur un col ouvert dudit récipient. 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 nozzle and being mounted in a sealed manner on an open neck of said container.
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 FR3 080844 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 FR3 080844 makes it possible to obtain a precise 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. 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 prevents the product from returning to the bottle when the chamber is used.
[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 peut être placé dans la partie centrale rigide de l’embout. [0007] This device provides for a location for a filter whose purpose is to make the air entering the bottle sterile in order to compensate for the depression created by the distribution of a portion of product; this filter can be 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] L’inconvénient majeur de ce type de dispositif lorsqu’il est amené à distribuer un produit semi-fluide ou visqueux réside dans la difficulté à remplir la chambre de dosage lorsque l’appui sur la partie souple cesse et qu’une dépression 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 insuffisante pour remplir cor- rectement la chambre de dosage. Cette force d’aspiration doit être suffisante pour vaincre les forces antagonistes dues au passage du produit semi-fluide ou visqueux dans les conduits qui l’acheminent dans la chambre et à l’ouverture du clapet anti- retour. [0009] The major drawback of this type of device when it has to dispense a semi-fluid or viscous product lies in the difficulty of filling the metering chamber when the pressure on the flexible part ceases and a depression 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 correctly fill the metering chamber. This suction force must be sufficient to overcome the antagonistic forces due to the passage of the semi-fluid or viscous product in the ducts which carry it into the chamber and to the opening of the non-return valve.
[0010] Or cette capacité d’aspiration du produit par la partie souple de l’embout est néces- sairement faible compte tenu de sa structure en élastomère ou en élastomère thermo- plastique. [0010] However, this capacity for suction of the product by the flexible part of the endpiece is necessarily low given its elastomer or thermoplastic elastomer structure.
[0011] Cet inconvénient peut conduire l’utilisateur à considérer que le dispositif est dé- fectueux. [0011] This drawback can lead the user to consider that the device is defective.
[0012] Le but principal de l’invention est de permettre la distribution de produits semi- fluides ou visqueux pouvant être conservés et distribués stérilement. [0012] The main purpose of the invention is to allow the distribution of semi-fluid or viscous products that can be stored and distributed sterilely.
[0013] 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. RÉSUMÉ [0013] More generally, the object of the invention is to remedy the drawbacks of analogous 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. SUMMARY
[0014] 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 : un récipient rigide contenant le produit à conditionner et distribuer ; un accessoire de distribution dont le récipient est muni comportant un embout externe muni d’une partie souple et d’une partie rigide et permettant de distribuer le produit, au moins une chambre de dosage étant prévue à l’intérieur de l’embout ; avec la particularité que l’embout est actionnable par la partie souple et permet au produit d’être expulsé vers l’extérieur du dispositif lorsque ladite au moins une chambre remplie de produit est comprimée par sollicitation de la partie souple mais ne permettant pas à l’air d’entrer à l’intérieur du récipient lorsque ladite partie souple n’est plus sollicitée, un clapet antiretour permettant au produit contenu dans le récipient de pénétrer dans ladite au moins une chambre lorsque la partie souple n’est plus sollicitée mais s’opposant au retour du produit dans le récipient lorsque ladite partie souple est sollicitée, et se caractérisant en ce que le dispositif inclut un ensemble de renouvellement de l’air comportant un filtre en coopération avec une valve permettant l’entrée de l’air dans le récipient mais s’opposant à toute sortie d’air ou de liquide à l’extérieur dudit récipient, et dans lequel au moins une languette élastique raccordée à la partie rigide et entourée par l’embout forme des moyens repousseurs pour rappeler la partie souple vers une position par défaut écartée d’une tige centrale de la partie rigide, pour le remplissage en produit de ladite au moins une chambre de dosage lorsque la partie souple n’est plus sollicitée. [0014] With a view to improving the situation, according to the invention there is proposed a device for packaging and dispensing a product, generally liquid, semi-fluid or viscous, comprising: a rigid container containing the product to be packaged and distribute; a dispensing accessory with which the receptacle is fitted comprising an outer end piece fitted with a flexible part and a rigid part and making it possible to dispense the product, at least one metering chamber being provided inside the end piece; with the particularity that the tip is actuated by the flexible part and allows the product to be expelled out of the device when said at least one chamber filled with product is compressed by stressing the flexible part but not allowing air to enter inside the container when said flexible part is no longer stressed, a non-return valve allowing the product contained in the container to enter said at least one chamber when the flexible part is no longer stressed but opposing the return of the product into the container when said flexible part is stressed, and characterized in that the device includes a set for renewing the air comprising a filter in cooperation with a valve allowing the entry of air into the container but opposing any outlet of air or liquid outside of said container, and in which at least one elastic tab connected to the rigid part surrounded by the tip forms pushing means to return the flexible part to a default position away from a central rod of the rigid part, for filling with product of said at least one metering chamber when the flexible part is no longer stressed.
[0015] Grâce à ces dispositions, il est permis d’améliorer l’effet aspiration du produit vers l’accessoire de distribution, par un retour automatique et rapide (dès l’arrêt de la solli- citation de la partie souple de l’embout) à un état correctement déployé de l’embout délimitant la chambre de dosage. [0015] Thanks to these provisions, it is possible to improve the suction effect of the product towards the dispensing accessory, by an automatic and rapid return (as soon as the load on the flexible part of the tip) to a correctly deployed state of the tip delimiting the metering chamber.
[0016] Autrement dit, en sollicitant de l’intérieur l’embout vers sa position déployée avec un périmètre maximal, après la distribution d’une dose, la ou les languettes élastiques forment des moyens repousseurs de la partie souple de l’embout, qui est écartée (au moins localement) de la tige centrale de la partie rigide. [0016] In other words, by pressing the tip from the inside towards its deployed position with a maximum perimeter, after the distribution of a dose, the elastic tab(s) form pushing means for the flexible part of the tip, which is separated (at least locally) from the central rod of the rigid part.
[0017] Selon une particularité, le déplacement de languette(s) peut être facilité par un effet de levier, la zone d’actionnement sur la partie souple coïncidant avec une extrémité de languette élastique. [0017]According to one feature, the movement of the tongue(s) can be facilitated by a leverage effect, the actuation zone on the flexible part coinciding with an end of the elastic tongue.
[0018] Chaque languette peut être plus longue que large, et la longueur de la languette dépasse la dimension axiale de la zone d’actionnement. [0018] Each tongue may be longer than it is wide, and the length of the tongue exceeds the axial dimension of the actuation zone.
Eventuellement, la zone d’actionnement correspond à une boursouflure ou un renflement dans l’embout, dans l’état non sollicité de ce dernier. Une telle zone est ainsi bien perceptible en étant typiquement distante et/ou espacée axialement du récipient. Optionally, the actuation zone corresponds to a blister or a bulge in the tip, in the unsolicited state of the latter. Such a zone is thus clearly perceptible by being typically remote and/or axially spaced from the container.
[0019] La partie souple de l’embout peut être réalisée en un matériau différent, plus dé- formable, que le matériau constitutif des languettes. On comprend que chaque languette est intrinsèquement très peu déformable, par exemple non pliable de plus de 45° par rapport à une configuration plate (angle plat), d’une extrémité à une autre, sans rupture du matériau. [0019] The flexible part of the end piece can be made of a different, more deformable material than the material of which the tongues are made. It is understood that each tongue is intrinsically very little deformable, for example not bendable by more than 45° with respect to a flat configuration (flat angle), from one end to another, without breaking the material.
[0020] Dans divers modes de réalisation selon l’invention, on peut avoir recours en outre à une ou plusieurs des dispositions suivantes : [0021] Chaque languette est plus mince qu’une portion de la partie souple recouvrant la languette et/ou chaque languette peut présenter éventuellement une épaisseur sen- siblement constante, au moins pour ce qui concerne une portion de languette di- rectement en contact avec la partie souple. In various embodiments according to the invention, one can also use one or more of the following provisions: [0021]Each tongue is thinner than a portion of the flexible part covering the tongue and/or each tongue may optionally have a substantially constant thickness, at least as regards a portion of the tongue directly in contact with the flexible part.
[0022] Optionnellement l’au moins une languette élastique se situe à l’intérieur de l’au moins une chambre de dosage. [0022] Optionally, the at least one elastic tab is located inside the at least one metering chamber.
[0023] Préférentiellement l’au moins une languette élastique fait partie intégrante d’une pièce incluant ladite partie rigide et qui appartient à l’accessoire de distribution qui s’étend suivant un axe longitudinal du dispositif, chaque languette étant réalisée de préférence en un matériau plus rigide que celui de la partie souple afin de présenter une plus grande résistance à la déformation, [0023] Preferably, the at least one elastic tab is an integral part of a part including said rigid part and which belongs to the dispensing accessory which extends along a longitudinal axis of the device, each tab being preferably made in one more rigid material than that of the flexible part in order to present a greater resistance to deformation,
[0024] Dans une variante l’au moins une languette présente dans la zone de raccordement à ladite partie rigide un orifice permettant de faciliter le passage du produit à distribuer vers l’au moins une chambre de dosage. [0024] In a variant, the at least one tab present in the connection zone to said rigid part has an orifice making it easier to pass the product to be dispensed to the at least one metering chamber.
[0025] Eventuellement, l’embout est actionnable pour distribuer, à une extrémité libre axiale de cet embout, une dose de produit, prélevée via une sortie de prélèvement du récipient. [0025] Optionally, the tip is operable to dispense, at a free axial end of this tip, a dose of product, sampled via a sample outlet of the container.
L’embout peut optionnellement présenter un accroissement de sa section externe de . façon à présenter un périmètre localement plus grand dans une région annulaire coïncidant avec une extrémité distale (la plus éloignée du récipient) de la languette, par' comparaison avec partie de l’embout qui est comparativement plus proche du récipient. The tip can optionally have an increase in its external section of . so as to present a locally larger perimeter in an annular region coinciding with a distal end (farthest from the container) of the tongue, in comparison with part of the tip which is comparatively closer to the container.

DESCRIPTION DE MODES DE REALISATION PREFERES DE L’INVENTION DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
[0030] Le dispositif tel que représenté sur la [Fig.l], incluant un récipient 1 contenant le produit 2 à distribuer et un accessoire de distribution 3, se présente dans la confi- guration dont dispose l’utilisateur avant toute utilisation. [0030] The device as shown in [Fig.l], including a container 1 containing the product 2 to be dispensed and a dispensing accessory 3, is in the configuration available to the user before any use.
[0031] L’accessoire de distribution 3 peut former un embout qui présente ici une paroi tubulaire externe. Cette paroi externe s’étend typiquement autour d’un axe longitudinal de l’embout. Au moins une chambre de dosage 9 est délimitée radialement entre cette paroi externe et la partie, rigide 4. Sur la [Fig.l], on peut voir que la ou les chambres de dosage 9 sont vides de produit 2 et que la partie souple 7 ou partie d’actionnement de l’accessoire de distribution 3 n’a pas été sollicitée. [0031] The dispensing accessory 3 can form a tip which here has an outer tubular wall. This outer wall typically extends around a longitudinal axis of the end piece. At least one metering chamber 9 is delimited radially between this outer wall and the rigid part 4. In [Fig.l], it can be seen that the metering chamber(s) 9 are empty of product 2 and that the flexible part 7 or actuating part of the dispensing accessory 3 has not been requested.
[0032] Le dispositif est pourvu d’au moins une languette 8 à effet de rappel élastique, mobile en réponse à une sollicitation sur la partie souple 7 de l’accessoire de dis- tribution 3. La languette 8 peut être rigide, à l’exception d’une zone charnière, cette languette 8 faisant office de ressort. Sur la [Fig.l], la languette 8 se trouve dans sa position initiale, décollée de la tige centrale de la partie rigide 4, par exemple en s’étendant longitudinalement (parallèlement à la tige centrale de la partie rigide 4), depuis une zone de jonction avec la partie rigide 4. Chaque languette 4 peut être reliée à la portion de base de la partie rigide 4, en s’étendant longitudinalement vers l’extérieur, parallèlement à la tige centrale de la partie rigide 4. [0032] The device is provided with at least one tongue 8 with an elastic return effect, movable in response to a stress on the flexible part 7 of the dispensing accessory 3. The tongue 8 can be rigid, at the Except for a hinge zone, this tongue 8 acting as a spring. In [Fig.l], the tongue 8 is in its initial position, detached from the central rod of the rigid part 4, for example by extending longitudinally (parallel to the central rod of the rigid part 4), from a junction zone with the rigid part 4. Each tab 4 can be connected to the base portion of the rigid part 4, extending longitudinally outwards, parallel to the central rod of the rigid part 4.
[0033] Le clapet antiretour 10, ici associé à un orifice de prélèvement 11 pour l’acheminement du produit 2 vers l’accessoire de distribution 3, est fermé de façon à séparer le produit 2 contenu dans le récipient 1 de la chambre de dosage 9. Dans des options, ce clapet 10 est monté sur et/ou siège contre la portion de base de la portion rigide 4. [0034] La valve 14 permettant à l’air de renouvellement de pénétrer dans l’espace 15, libre de produit 2, du récipient 1, au travers du passage d’arrivée 12 situé dans la portion de base de la pallie rigide 4, puis du filtre 13, et s’opposant à toute sortie d’air ou de liquide 2 de l’intérieur vers l’extérieur du récipient 1 est fermée. The non-return valve 10, here associated with a sampling orifice 11 for conveying the product 2 to the dispensing accessory 3, is closed so as to separate the product 2 contained in the container 1 from the metering chamber 9. In options, this valve 10 is mounted on and/or seated against the base portion of the rigid portion 4. [0034] The valve 14 allowing the renewal air to penetrate into the space 15, free of product 2, of the container 1, through the inlet passage 12 located in the base portion of the rigid pallie 4, then the filter 13, and opposing any air or liquid 2 outlet from the inside to the outside of the container 1 is closed.
[0035] Lors de sa première utilisation le dispositif fonctionne de la manière suivante. [0035] During its first use, the device operates as follows.
[0036] Tel que représenté sur la [Fig.2] l’utilisateur exerce une pression latérale sur la paroi souple 7 ou partie d’actionnement de l’accessoire distributeur 3 suivant les flèches A ; A’. As shown in [Fig.2] the user exerts lateral pressure on the flexible wall 7 or actuating part of the dispenser accessory 3 along the arrows A; HAS'.
[0037] Cette pression entraîne la contraction de la chambre 9. SI du produit 2 est déjà présent initialement dans une telle chambre 9, cela provoque l’expulsion suivant la flèche B d’une dose 16 du produit 2 par écartement de l’extrémité 6 de la partie souple 3 d’actionnement par rapport à l’extrémité 5 de la tige centrale de la partie rigide 4 de l’accessoire de distribution 3. This pressure causes the contraction of the chamber 9. If the product 2 is already initially present in such a chamber 9, this causes the expulsion following the arrow B of a dose 16 of the product 2 by separation of the end 6 of the flexible actuating part 3 with respect to the end 5 of the central rod of the rigid part 4 of the dispensing accessory 3.
[0038] Sous l’effet de l’augmentation de la pression créée à l’intérieur de la chambre 9, le clapet antiretour 10 est plaqué contre la portion de base de la partie rigide 4, empêchant tout retour du liquide 2 vers l’intérieur du récipient 1 au travers de l’orifice 11. Under the effect of the increase in pressure created inside the chamber 9, the non-return valve 10 is pressed against the base portion of the rigid part 4, preventing any return of the liquid 2 towards the inside container 1 through orifice 11.
[0039] Dans cette phase la languette 8 se trouve entraînée par la partie souple 3 vers la tige centrale de la partie rigide 4 (dans une région intermédiaire située axialement entre la portion de base et l’extrémité libre) et se trouve plaquée contre cette dernière. In this phase the tongue 8 is driven by the flexible part 3 towards the central rod of the rigid part 4 (in an intermediate region located axially between the base portion and the free end) and is pressed against this last.
[0040] La [Fig.3] représente le dispositif lorsque l’utilisateur a relâché la pression sur la partie souple 3, que celle-ci est revenue à sa position initiale suivant les flèches C ; C’, et que sous l’effet de l’aspiration ainsi créée le produit 2 a : [0040] The [Fig.3] shows the device when the user has released the pressure on the flexible part 3, that it has returned to its initial position along the arrows C; C', and that under the effect of the suction thus created the product 2 has:
- traversé l’ orifice 11 de prélèvement suivant la flèche D, - passed through sampling orifice 11 along arrow D,
- soulevé le clapet 10, - lifted valve 10,
- traversé l’orifice en forme de lumière 16, situé par exemple à la base de la languette- passed through the hole in the shape of a light 16, located for example at the base of the tongue
8, 8,
- et rempli la chambre 9. - and filled room 9.
[0041] La sortie d’une portion de produit 2 de l’intérieur du récipient 1 vers la chambre 9 a créé une dépression dans la partie 15 libre de produit 2 du récipient 1. [0041] The exit of a portion of product 2 from the interior of container 1 towards chamber 9 created a depression in the free part 15 of product 2 of container 1.
[0042] Afin de compenser cette dépression un volume d’air de renouvellement cor- respondant au volume de produit 2 admis dans la chambre 9 entre dans la partie libre 15 du récipient 1 suivant la flèche E après avoir traversé le canal d’admission 12 situé dans la portion de base de la partie rigide 4, le filtre 13 et ouvert la valve 14. [0042] In order to compensate for this depression, a volume of renewal air corresponding to the volume of product 2 admitted into the chamber 9 enters the free part 15 of the container 1 along the arrow E after having passed through the inlet channel 12 located in the base portion of the rigid part 4, the filter 13 and open the valve 14.
[0043] On peut constater que la languette 8 a également repris sa position initiale par un effet ressort dû à son élasticité et qu’elle a ainsi contribué à l’effet d’aspiration dû au retour de la partie souple 3 à sa position initiale. It can be seen that the tongue 8 has also returned to its initial position by a spring effect due to its elasticity and that it has thus contributed to the suction effect due to the return of the flexible part 3 to its initial position. .
[0044] On a ainsi, grâce à l’effet ressort de la languette 8, contribué à l’aspiration du produit 2 dans la chambre 9 et rendu le remplissage de ladite chambre 9 plus facile qu’avec le retour élastique seul de la partie souple 3. We have thus, thanks to the spring effect of the tab 8, contributed to the suction of the product 2 in the chamber 9 and made the filling of said chamber 9 easier than with the elastic return only of the flexible part 3.
[0045] Cette combinaison de l’élasticité de la partie souple 3 et de la languette 8 peut être particulièrement utile dans le cas où le produit 2 est semi-fluide ou visqueux, This combination of the elasticity of the flexible part 3 and of the tongue 8 can be particularly useful in the case where the product 2 is semi-fluid or viscous,
[0046] 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 9 munie d’une seule languette, ou une ou des chambres de dosage ainsi que des languettes de forme quelconque. 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 9 provided with a single tab, or one or more metering chambers as well as tabs of any shape.
