Description

DISPOSITIF DE CONDITIONNEMENT ET DE DISTRIBUTION DE PRODUITS FLUIDES  DEVICE FOR CONDITIONING AND DISPENSING FLUID PRODUCTS
A POMPE MANUELLE  MANUAL PUMP
La présente invention concerne un dispositif perfectionné de conditionnement et de distribution de produits fluides, et plus particulièrement un dispositif assurant la parfaite conservation du produit fluide contenu dans le flacon entre le remplissage et la première utilisation. The present invention relates to an improved device for packaging and dispensing fluid products, and more particularly to a device ensuring the perfect preservation of the fluid contained in the bottle between the filling and the first use.
On sait que le maintien à l'abri du milieu extérieur des produits fluides contenus dans des dispositifs distributeurs est une condition importante de la préservation de leur composition, de leurs caractéristiques et par voie de conséquence de leur activité, en particulier pour les produits pharmaceutiques et cosmétiques. Si la durée d'utilisation par le patient est en général assez brève, quelques semaines, voire quelques jours, la période de stockage de ces dispositifs entre leur remplissage sur le lieu de production et leur première utilisation après avoir été mis dans le commerce est beaucoup plus longue. Les flacons remplis peuvent ainsi être stockés pendant plusieurs mois, voire plusieurs années dans des conditions parfois défavorables à une bonne conservation. On sait que le contact direct avec le milieu extérieur peut avoir des conséquences très néfastes sur la stabilité du produit contenu à l'intérieur de tels dispositifs du fait, notamment, de l'oxydation provoquée par l'oxygène contenu dans l'air, de la contamination microbienne ou encore de l'évaporation de substances actives ou de solvants présents dans la formulation.  It is known that the preservation of the external medium of the fluid products contained in dispensing devices is an important condition of the preservation of their composition, of their characteristics and consequently of their activity, in particular for pharmaceutical products and cosmetics. If the duration of use by the patient is generally quite short, a few weeks, even a few days, the period of storage of these devices between filling them at the place of production and their first use after being put on the market is much longer. The filled vials can thus be stored for several months or even years in conditions sometimes unfavorable to good conservation. It is known that the direct contact with the external environment can have very detrimental consequences on the stability of the product contained inside such devices, in particular because of the oxidation caused by the oxygen contained in the air, microbial contamination or evaporation of active substances or solvents present in the formulation.
Pour éviter ce contact direct avec le milieu extérieur, de nombreux dispositifs ont été développés qui permettent, lors de la phase d'utilisation, d'extraire le produit du dispositif sans que de l'air ne pénètre à l'intérieur, au contact du produit restant dans le dispositif. Ces dispositifs sont généralement désignés sous le terme "airless".  To avoid this direct contact with the external environment, many devices have been developed that allow, during the use phase, to extract the product from the device without air entering inside, in contact with the device. product remaining in the device. These devices are generally referred to as "airless".
Les dispositifs de conditionnement et de distribution de produits fluides connus comportent généralement un récipient à coque rigide dans lequel se déplace un piston repoussant le produit vers l'orifice d'admission dans la chambre de dosage et l'isolant de l'air qui pénètre au-dessous du piston. On connaît aussi des dispositifs à récipient rigide dans lequel est placée une poche souple déformable qui se rétracte au fur et à mesure que le produit en est extrait. Le produit restant dans la poche est maintenu à l'abri de l'air, tandis que l'expulsion du produit hors de la poche peut être obtenue au moyen d'une pompe sans reprise d'air, ou "airless". The devices for packaging and dispensing fluid products known generally comprise a rigid-shell container in which moves a piston pushing the product to the inlet orifice in the chamber dosing and air insulation that penetrates below the piston. Also known are rigid container devices in which is placed a deformable flexible pouch which retracts as the product is extracted. The product remaining in the pocket is kept out of the air, while the expulsion of the product out of the pocket can be obtained by means of a pump without air intake, or "airless".
Dans tous les cas un évent est prévu, généralement dans le fond ou dans le col du flacon, pour permettre à l'air extérieur de pénétrer dans l'espace situé entre le fond du flacon et le piston ou entre le flacon et la poche à chaque actionnement de la pompe et permettre ainsi au piston de se déplacer ou à la poche de se rétracter en maintenant une pression suffisante sur leurs parois. Un exemple de réalisation suivant cette technique est décrit dans le brevet FR 2.723.356 relatif à un dispositif comportant une poche en matière plastique souple, telle que polyéthylène ou polypropylène, dans un récipient rigide dont le col comporte une entrée d'air.  In all cases a vent is provided, usually in the bottom or in the neck of the bottle, to allow the outside air to enter the space between the bottom of the bottle and the piston or between the bottle and the bag. each actuation of the pump and thus allow the piston to move or the pocket to retract while maintaining sufficient pressure on their walls. An exemplary embodiment according to this technique is described in patent FR 2,723,356 relating to a device comprising a flexible plastic bag, such as polyethylene or polypropylene, in a rigid container whose neck has an air inlet.
Un autre exemple de flacon-poche est décrit dans le brevet FR 2.827.844 relatif à un dispositif comportant une poche souple étanche placée dans un flacon rigide, associée à une pompe, dans lequel la poche comprend une paroi cylindrique constituée par une feuille métallique ou de matière plastique enroulée sur les bords de deux flasques dont l'un forme le fond de la poche et l'autre une bague de fixation au flacon et à la pompe.  Another example of a pocket bottle is described in patent FR 2,827,844 relating to a device comprising a sealed flexible bag placed in a rigid bottle, associated with a pump, in which the bag comprises a cylindrical wall constituted by a metal sheet or plastic material wound on the edges of two flanges one of which forms the bottom of the pocket and the other a ring for fixing the bottle and the pump.
Le principe de fonctionnement des pompes doseuses utilisées dans de tels dispositifs de distribution de produits fluides, liquides ou pâteux est bien connu. Une pompe doseuse manuelle est généralement montée sur un flacon contenant le produit à distribuer et elle est constituée d'une chambre doseuse présentant un volume déterminé, d'un piston susceptible de se déplacer dans la chambre sous l'action d'un poussoir, et d'au moins deux clapets. Le clapet inférieur, ou clapet d'admission, situé à l'entrée de la chambre et contrôlant la communication avec l'intérieur du flacon, est fermé lorsque le poussoir est enfoncé tandis que le clapet supérieur, à la sortie de la chambre, est ouvert, laissant passer le produit expulsé de la chambre par le déplacement du piston, puis, lorsque le poussoir est relâché, le piston remonte dans la chambre sous l'action d'un ressort, le clapet supérieur se referme tandis que le clapet inférieur s'ouvre, permettant le remplissage de la chambre en vue d'une nouvelle distribution d'une dose de produit. The operating principle of the metering pumps used in such dispensing devices for fluid, liquid or pasty products is well known. A manual metering pump is generally mounted on a bottle containing the product to be dispensed and consists of a metering chamber having a determined volume, a piston capable of moving in the chamber under the action of a pusher, and at least two valves. The lower valve, or inlet valve, located at the entrance of the chamber and controlling the communication with the interior of the bottle, is closed when the pusher is depressed while the upper valve, at the exit of the chamber, is open, allowing the expelled product to pass of the chamber by the displacement of the piston, then, when the pusher is released, the piston rises in the chamber under the action of a spring, the upper valve closes while the lower valve opens, allowing the filling of the chamber for a new distribution of a dose of product.
Les pompes généralement associées aux poches souples doivent assurer une bonne étanchéité et pouvoir fonctionner quelle que soit la position, verticale ou inclinée, du flacon. Le brevet FR 2.669.379 décrit une pompe doseuse procurant une bonne étanchéité même en cas de changement de position, du type à piston axial portant un piston flottant coulissant, comportant trois clapets. Le brevet FR 2.731 .992 décrit un flacon distributeur dont le poussoir est combiné à un piston fixe solidaire du flacon pour constituer une pompe. Un autre exemple de pompe airless est décrit dans la demande WO 04/054721 relatif à une pompe pour flacon- poche.  The pumps generally associated with the flexible bags must ensure a good seal and be able to operate whatever the position, vertical or inclined, of the bottle. Patent FR 2,669,379 describes a metering pump providing a good seal even in the case of a change of position, of the axial piston type carrying a sliding floating piston, comprising three valves. FR 2,731,992 discloses a dispensing bottle whose pusher is combined with a fixed piston integral with the bottle to form a pump. Another example of an airless pump is described in patent application WO 04/054721 relating to a pump for a pocket bottle.
Des dispositifs d'obturation existent pour éviter que l'air ne s'introduise dans la buse de sortie de la pompe et ne puisse dégrader le produit se trouvant dans cette buse après chaque actionnement de la pompe par l'utilisateur. Par exemple le brevet FR 2.785.878 décrit un distributeur à pompe manuelle dont la buse de sortie est munie d'un obturateur se refermant automatiquement quand la pompe est au repos.  Shut-off devices exist to prevent air from entering the outlet nozzle of the pump and can degrade the product in this nozzle after each actuation of the pump by the user. For example the patent FR 2,785,878 describes a manual pump dispenser whose outlet nozzle is provided with a shutter closing automatically when the pump is at rest.
Tous ces dispositifs offrent un niveau de protection satisfaisant lors de la phase d'utilisation du produit dont la durée est généralement brève.  All these devices offer a satisfactory level of protection during the use phase of the product, the duration of which is generally short.
Cependant, certains processus physico-chimiques contribuent à la dégradation des produits contenus dans les flacons, comme par exemple la perméation des gaz à travers les matériaux, l'évaporation par les micro fuites du circuit de la pompe ou encore le contact prolongé entre le produit contenu et certains matériaux complexes du dispositif, comme par exemple les clapets de la pompe, mais ces processus ont des cinétiques très lentes et n'ont donc aucune influence pendant la durée d'utilisation. En revanche, la durée importante de stockage peut permettre à ces processus lents d'aboutir à une dégradation progressive des produits qui risquent alors d'être sensiblement dénaturés au moment où ils seront utilisés. However, certain physicochemical processes contribute to the degradation of the products contained in the flasks, such as the permeation of gases through the materials, the evaporation by the micro leaks of the pump circuit or the prolonged contact between the product. and some complex materials of the device, such as the valves of the pump, but these processes have very slow kinetics and therefore have no influence during the period of use. On the other hand, the long duration of storage can allow these slow processes to lead to a degradation. products that may then be significantly denatured at the time they are used.
Il est donc indispensable de veiller à ce que les produits contenus dans les flacons soient parfaitement protégés contre ces processus de dégradation en évitant le plus possible les échanges de l'intérieur du flacon vers l'extérieur aussi bien que de l'extérieur vers l'intérieur et ce pendant toute la phase de stockage, quelle que soit sa durée.  It is therefore essential to ensure that the products contained in the flasks are perfectly protected against these degradation processes by avoiding as much as possible the exchange of the inside of the flask towards the outside as well as from outside to the outside. inside during the entire storage phase, whatever its duration.
Ces processus de dégradation peuvent se produire par l'évent nécessaire à tout dispositif "airless" puisque la fonction de cet évent est précisément de permettre que de l'air extérieur vienne au contact direct du piston ou de la poche induisant ainsi un risque d'oxydation du produit contenu dans le dispositif.  These degradation processes can occur through the vent required for any "airless" device since the function of this vent is precisely to allow external air to come into direct contact with the piston or the pocket thus inducing a risk of oxidation of the product contained in the device.
Ils peuvent également se produire par les micro-fuites, inévitables dans le circuit de la pompe qui comporte de nombreuses pièces mobiles, et en particulier par un défaut d'étanchéité au niveau de la jonction entre la pompe et le flacon ou la poche ou encore au niveau des clapets de la pompe.  They can also occur by micro-leaks, inevitable in the circuit of the pump which has many moving parts, and in particular by a lack of sealing at the junction between the pump and the bottle or the pocket or even at the level of the valves of the pump.
Ce dernier risque est sensiblement aggravé lorsque le produit contenu reste en contact de façon prolongée avec le clapet d'admission de la pompe comme cela peut se produire si le dispositif est stocké en position horizontale ou verticale inversée. Certains ingrédients contenus dans les matériaux des clapets, réalisés par nature en matière souple comme par exemple en élastomères, peuvent migrer dans le produit contenu et modifier sa composition de façon gênante. L'inverse peut également se produire et des ingrédients contenus dans le produit peuvent migrer dans le matériau des clapets, modifiant ainsi leurs propriétés dimensionnelles et mécaniques. Ce processus peut conduire alors à une perte d'étanchéité des clapets de la pompe et favoriser la dégradation du produit par contact avec le milieu extérieur.  The latter risk is substantially aggravated when the contained product remains in prolonged contact with the pump inlet valve as may occur if the device is stored in a horizontal or inverted vertical position. Some ingredients contained in the materials of the valves, made by nature of flexible material such as elastomers, can migrate into the product contained and modify its composition in a troublesome manner. The opposite can also happen and ingredients contained in the product can migrate into the material of the valves, thus changing their dimensional and mechanical properties. This process can then lead to a loss of sealing of the valves of the pump and promote degradation of the product by contact with the external environment.
Dans tous les modèles de flacons distributeurs à pompe manuelle précités, la protection du produit contenu dans le flacon ou la poche vis-à-vis de l'extérieur est la même, que le flacon soit en cours de stockage ou en cours d'utilisation. Or comme indiqué ci-dessus, il est important qu'une bonne protection soit assurée tout particulièrement au cours du stockage du dispositif distributeur avant la première utilisation. In all of the aforementioned manual pump dispenser vials, the protection of the product contained in the vial or bag from the outside is the same regardless of whether the vial is being stored or in use. . As stated above, it is important that good protection be ensured especially during storage of the dispensing device before the first use.
Certains systèmes de sécurité ont été proposés pour protéger le contenu d'un flacon ou d'une poche au cours du stockage. Ainsi, la demande de brevet WO 2001019217 décrit un flacon à pompe manuelle destiné à délivrer des substances se trouvant chacune dans un récipient indépendant afin qu'elles ne soient pas mélangées avant actionnement de la pompe. A cet effet, l'ouverture des récipients est obturée par un film tant que la pompe est maintenue au-dessus du film au moyen d'un anneau de blocage qui est enlevé avant la première utilisation. Un dispositif similaire est décrit par les brevets KR 200416576 et JP 2008030838.  Some security systems have been proposed to protect the contents of a bottle or pouch during storage. Thus, patent application WO 2001019217 discloses a manual pump bottle for dispensing substances each in an independent container so that they are not mixed before actuating the pump. For this purpose, the opening of the containers is closed by a film as long as the pump is held above the film by means of a locking ring which is removed before the first use. A similar device is described by patents KR 200416576 and JP 2008030838.
La présente invention a précisément pour objet un dispositif de conditionnement et de distribution de produits fluides, à pompe manuelle montée sur un flacon contenant le produit à distribuer, ou renfermant une poche contenant le produit, permettant de réduire au minimum les échanges entre l'intérieur et l'extérieur du dispositif pendant toute la période comprise entre le remplissage et la première utilisation.  The present invention specifically relates to a device for packaging and dispensing fluid products, with manual pump mounted on a bottle containing the product to be dispensed, or containing a bag containing the product, to minimize the exchanges between the interior. and the outside of the device for the entire period between filling and first use.
L'invention a aussi pour objet un dispositif de sécurité pour pompe d'un flacon distributeur du type ci-dessus, empêchant toute utilisation accidentelle de la pompe au cours du stockage et permettant à l'utilisateur final de s'assurer que le produit n'a pas été utilisé ou modifié avant qu'il l'utilise lui-même.  The invention also relates to a pump safety device of a dispenser bottle of the above type, preventing any accidental use of the pump during storage and allowing the end user to ensure that the product no has not been used or modified before it uses it itself.
L'invention a encore pour objet un flacon distributeur de produits fluides comprenant une telle pompe sécurisée.  The invention also relates to a dispensing bottle of fluid products comprising such a pump secured.
L'expression "produit fluide" utilisée dans la présente demande signifie un produit non solide à température ordinaire susceptible de s'écouler hors d'un récipient le contenant, tel qu'un liquide, une lotion, une émulsion, une pâte, un gel, un produit pour pulvérisation, etc. Ces produits fluides peuvent être utilisés dans divers domaines techniques, et peuvent être par exemple des produits cosmétiques, des produits pharmaceutiques, des produits d'entretien, etc. Le dispositif de conditionnement et de distribution de produits fluides suivant l'invention comprend une pompe du type pompe manuelle pour flacon distributeur de produits fluides, montée sur un flacon contenant le produit à distribuer, et elle comporte un élément amovible intercalé entre la pompe et le col du flacon, ainsi qu'un obturateur solidaire de la pompe, susceptible de fermer le circuit de passage du produit à distribuer entre l'intérieur du flacon et la pompe lorsque l'élément amovible est en place. The term "fluid product" used in the present application means a non-solid product at ordinary temperature that can flow out of a container containing it, such as a liquid, a lotion, an emulsion, a paste, a gel , a spray product, etc. These fluid products can be used in various technical fields, and can be for example cosmetic products, pharmaceuticals, cleaning products, etc. The device for packaging and dispensing fluid products according to the invention comprises a pump of the manual pump type for a fluid dispenser bottle, mounted on a bottle containing the product to be dispensed, and it comprises a removable element interposed between the pump and the dispenser. neck of the bottle, and a shutter secured to the pump, capable of closing the passage of the product to be dispensed between the inside of the bottle and the pump when the removable element is in place.
Plus précisément, l'élément amovible est placé entre la base de la jupe de la pompe et l'épaulement formé dans le col du flacon destiné à recevoir la pompe, par exemple par clippage ou par emboîtement. Ainsi, cet élément amovible maintient la pompe dans une position surélevée par rapport au flacon rigide de telle sorte que, dans cette position, l'obturateur coopère avec le col du flacon ou de la poche pour fermer le circuit de passage du produit.  More specifically, the removable element is placed between the base of the skirt of the pump and the shoulder formed in the neck of the flask intended to receive the pump, for example by clipping or by interlocking. Thus, this removable element keeps the pump in an elevated position relative to the rigid bottle so that, in this position, the shutter cooperates with the neck of the bottle or the bag to close the product passage circuit.
Suivant une forme de réalisation, l'élément amovible est constitué par un double anneau à section en U dont les branches enserrent les faces externe et interne de la jupe de la pompe, et dont la base, reliant les deux branches, est frangible. L'anneau externe écarte le bord de la jupe de sa position de fonctionnement où il est en contact avec le col du flacon. L'arrachage de l'anneau externe avec rupture de la base le reliant à l'anneau interne, libère la pompe qui peut être amenée dans sa position définitive de fonctionnement.  According to one embodiment, the removable element is constituted by a double U-section ring whose branches enclose the outer and inner faces of the skirt of the pump, and whose base, connecting the two branches, is frangible. The outer ring separates the edge of the skirt from its operating position where it is in contact with the neck of the bottle. The tearing of the outer ring with rupture of the base connecting it to the inner ring, frees the pump which can be brought into its final operating position.
Suivant une autre forme de réalisation, l'élément amovible est constitué d'un anneau simple enserrant la base de la face externe de la jupe de la pompe. Pour la première utilisation, l'arrachage de l'anneau comme ci-dessus libère la pompe qui peut alors être mise dans sa position définitive de fonctionnement.  According to another embodiment, the removable element consists of a single ring enclosing the base of the outer face of the skirt of the pump. For the first use, pulling the ring as above releases the pump which can then be put in its final operating position.
L'obturateur est avantageusement fixé sur la base de la pompe et est en contact étanche avec la face interne du col du flacon ou de la poche contenant le produit, quand l'élément amovible est en place sur la pompe. Suivant une caractéristique préférentielle de l'invention, l'obturateur comporte au moins un bord annulaire coopérant avec le bord interne du support de la pompe lorsque l'élément amovible est en place sur la pompe. Suivant une autre caractéristique, l'élément amovible a une épaisseur telle que, une fois cet élément enlevé, la pompe puisse être enfoncée sur son support pour être mise en place définitivement et libérer un espace suffisant entre l'obturateur, solidaire de la pompe, et le support, pour le passage du fluide. The shutter is advantageously fixed on the base of the pump and is in sealing contact with the inner face of the neck of the bottle or the bag containing the product, when the removable element is in place on the pump. According to a preferred feature of the invention, the shutter comprises at least one annular edge cooperating with the inner edge of the pump support when the removable element is in place on the pump. According to another characteristic, the removable element has a thickness such that, once this element has been removed, the pump can be pressed onto its support to be put in place definitively and to release a sufficient space between the shutter, integral with the pump, and the support, for the passage of the fluid.
Suivant une variante de l'invention, la face inférieure de l'obturateur peut être revêtue d'une pièce ou d'un film, par exemple un film métallique imperméable aux gaz, ayant pour effet de rendre cet obturateur imperméable aux gaz. La pièce ou le film métallique, par exemple un film contenant une feuille d'aluminium, peut être avantageusement placé sur la face inférieure de l'obturateur ou inséré dans l'épaisseur de cette face inférieure qui est susceptible d'entrer en contact avec le produit contenu dans le flacon ou la poche.  According to a variant of the invention, the lower face of the shutter may be coated with a part or a film, for example a gas impermeable metal film, having the effect of making this shutter impervious to gases. The piece or the metal film, for example a film containing an aluminum foil, may advantageously be placed on the underside of the shutter or inserted into the thickness of this lower face which is capable of coming into contact with the shutter. product contained in the vial or pouch.
Le dispositif suivant la présente invention possède l'avantage d'assurer une bonne étanchéité entre l'intérieur et l'extérieur du flacon, ou de la poche le cas échéant, de telle sorte que l'air extérieur ne puisse pénétrer ni par l'évent lorsqu'il est situé dans la pompe ni par le circuit de la pompe et atteindre le produit contenu dans le flacon, ou dans la poche, et que le produit lui-même ou certains ingrédients qu'il contient ne puissent pas fuir par la pompe, avant le premier actionnement du poussoir par l'utilisateur.  The device according to the present invention has the advantage of ensuring a good seal between the inside and outside of the bottle, or the bag if necessary, so that the outside air can not penetrate through the when it is located in the pump or by the pump circuit and reach the product contained in the bottle, or in the bag, and that the product itself or certain ingredients it contains can not escape through the pump, before the first actuation of the pusher by the user.
De plus, quand l'élément amovible est en place sur la pompe, l'obturateur est en position de fermeture et il forme alors une paroi isolante entre le produit se trouvant dans le flacon, ou dans la poche, et la pompe, ce qui permet de limiter les volumes libres au-dessus du produit et donc de limiter l'évaporation éventuelle du produit par équilibre de pression.  In addition, when the removable element is in place on the pump, the shutter is in the closed position and it then forms an insulating wall between the product in the bottle, or in the pocket, and the pump, which allows to limit the free volumes above the product and thus limit the possible evaporation of the product by pressure balance.
La présence de l'élément amovible en place sur la pompe montre à l'utilisateur que le dispositif de conditionnement et de distribution de produit fluide n'a pas encore été utilisé et constitue donc un indicateur de la qualité originelle du produit qui y est contenu.  The presence of the removable element in place on the pump shows the user that the device for packaging and dispensing fluid product has not yet been used and is therefore an indicator of the original quality of the product contained therein .
En outre, lorsque l'obturateur est en position de fermeture, les clapets de la pompe se trouvent totalement isolés du produit contenu dans le flacon ou la poche, ce qui permet d'éviter toute interaction néfaste entre les deux pendant toute la période de stockage. L'obturateur étant réalisé de préférence en même matière que le flacon ou le col de la poche, ceci permet de limiter le nombre de matériaux de natures différentes susceptibles d'entrer en contact avec le produit à distribuer, pendant toute la période de stockage. In addition, when the shutter is in the closed position, the valves of the pump are completely isolated from the product contained in the bottle or the bag, which avoids harmful interaction between the two during the entire storage period. Since the shutter is preferably made of the same material as the flask or neck of the pouch, this makes it possible to limit the number of materials of different natures likely to come into contact with the product to be dispensed during the entire storage period.
La face inférieure de l'obturateur peut être operculée, c'est-à-dire recouverte par un film, de préférence en même matière que la poche pour éviter ou limiter toute discontinuité de matière en contact avec le produit contenu dans la poche pendant la période de stockage avant la première utilisation.  The underside of the shutter can be sealed, that is to say covered by a film, preferably of the same material as the bag to avoid or limit any discontinuity of material in contact with the product contained in the pocket during the storage period before first use.
La pompe utilisée dans l'invention peut être avantageusement une pompe dite "airless", sans entrée d'air, comprenant un piston pouvant se déplacer dans la chambre de dosage sous l'action d'un poussoir, un clapet d'entrée contrôlant le passage du flacon vers la chambre, et un clapet de sortie pouvant obturer la chambre.  The pump used in the invention may advantageously be a so-called "airless" pump, without air inlet, comprising a piston that can move in the metering chamber under the action of a pusher, an inlet valve controlling the passage of the bottle to the chamber, and an outlet valve that can close the chamber.
La pompe de l'invention comprend donc une pompe usuelle simplement complétée par deux éléments, à savoir l'élément amovible placé sur la périphérie et l'obturateur à la base de la pompe.  The pump of the invention therefore comprises a usual pump simply supplemented by two elements, namely the removable element placed on the periphery and the shutter at the base of the pump.
La mise en œuvre peut être réalisée très simplement. L'obturateur et l'élément amovible sont pré-assemblés à la pompe de sorte que lors du conditionnement, on procède au remplissage de la poche (ou du flacon, le cas échéant) avec le produit, puis on met simplement la pompe en place comme toute autre pompe, par exemple par clippage. Lors de la première utilisation, l'utilisateur arrache l'élément amovible, par exemple au moyen d'une languette, et appuie sur la pompe, ou sur son poussoir, pour l'amener dans sa position définitive. Ce mouvement a pour effet de déplacer verticalement la pompe vers la bas et par conséquence l'obturateur fixé à la base de la pompe, et de libérer le passage du flacon vers la pompe pour permettre l'extraction du produit contenu dans la poche ou dans le flacon lorsque la pompe est actionnée.  The implementation can be done very simply. The shutter and the removable element are pre-assembled at the pump so that during packaging, the bag (or bottle, if any) is filled with the product, and then the pump is simply put in place. like any other pump, for example by clipping. During the first use, the user tears the removable element, for example by means of a tongue, and presses the pump, or on its pusher, to bring it to its final position. This movement has the effect of moving the pump vertically downwards and consequently the shutter attached to the base of the pump, and to release the passage of the bottle to the pump to allow the extraction of the product contained in the pocket or in the bottle when the pump is actuated.
Le cas échéant, un capot protecteur peut être prévu par-dessus le poussoir de la pompe, prenant appui sur la pompe ou sur la bague de fixation au flacon. Le corps de la pompe est réalisé de manière usuelle en matière plastique telle que polypropylène de densité appropriée pour procurer les qualités mécaniques voulues. L'obturateur peut être en même matière que la bague de la poche, et sa face inférieure peut porter une pièce ou un film imperméable aux gaz, par exemple une feuille associant plusieurs couches de matières plastiques telles que le polyéthylène, le polypropylène, le polyéthylène téréphtalate (PET), l'EVOH (copolymère éthylène - alcool vinylique présentant de bonnes caractéristiques de barrière aux gaz), et/ou incluant une feuille d'aluminium métallique. If necessary, a protective cover may be provided over the pusher of the pump, bearing on the pump or on the ring fixing the bottle. The body of the pump is customarily made of plastic such as polypropylene of appropriate density to provide the desired mechanical properties. The shutter may be of the same material as the ring of the pocket, and its underside may carry a piece or film impermeable to gases, for example a sheet combining several layers of plastics such as polyethylene, polypropylene, polyethylene terephthalate (PET), EVOH (ethylene-vinyl alcohol copolymer exhibiting good gas barrier characteristics), and / or including a metallic aluminum foil.
Le flacon rigide peut être réalisé par exemple en toute matière appropriée telle qu'un polyéthylène ou un polypropylène de densité appropriée pour lui conférer les propriétés mécaniques voulues. L'extrémité de la buse de sortie de la pompe peut être munie d'un système complémentaire de fermeture en toute matière appropriée souple et élastique, et de préférence en élastomère nitrile, butyle, silicone ou TPE.  The rigid bottle may be made for example of any suitable material such as polyethylene or polypropylene of appropriate density to impart the desired mechanical properties. The end of the outlet nozzle of the pump may be provided with a complementary closure system of any suitable flexible and elastic material, and preferably of nitrile, butyl, silicone or TPE elastomer.
La poche souple peut être fabriquée par injection-soufflage ou par extrusion-soufflage, par exemple à partir de polyéthylène basse densité, polypropylène, polyamide, copolymère EVOH, ou par soudage, sur un support, d'un film multicouche, ou d'un film métallique revêtu d'un film plastique. La matière formant la poche peut être choisie en fonction de la nature du produit qui doit y être contenu. Ainsi un polyéthylène basse densité convient généralement pour des produits peu sensibles à l'action de l'air environnant, tandis qu'un film métallique revêtu d'un film plastique est mieux adapté à un produit sensible à l'oxydation.  The flexible bag may be manufactured by injection blow molding or by extrusion blow molding, for example from low density polyethylene, polypropylene, polyamide, EVOH copolymer, or by welding, on a support, a multilayer film, or a metal film coated with a plastic film. The material forming the pocket can be chosen according to the nature of the product which must be contained therein. Thus a low density polyethylene is generally suitable for products that are not very sensitive to the action of the surrounding air, while a metal film coated with a plastic film is better suited to an oxidation-sensitive product.

La Figure 1 montre un flacon rigide (1 ) portant une pompe sans reprise d'air (2) actionnée par un poussoir (3), montée sur une bague (4) encliquetée dans le col du flacon rigide (1 ) et solidarisée au col de la poche à paroi (5) souple et déformable contenant le produit à distribuer.  Figure 1 shows a rigid bottle (1) carrying a pump without air intake (2) actuated by a pusher (3), mounted on a ring (4) snapped into the neck of the rigid bottle (1) and secured to the neck the wall pocket (5) flexible and deformable containing the product to be dispensed.
La pompe (2) est raccordée de manière classique à la buse de sortie (6) prévue dans le poussoir (3) afin d'extraire le produit contenu dans la poche (5). La poche est obturée dans sa partie basse par la coupelle (7) fixée de manière étanche à la paroi souple (5).  The pump (2) is connected in a conventional manner to the outlet nozzle (6) provided in the pusher (3) in order to extract the product contained in the pocket (5). The pocket is closed in its lower part by the cup (7) sealingly attached to the flexible wall (5).
La jupe (8) de la pompe (2) est susceptible de venir en contact, par le bord (9) de sa base, avec l'épaulement (10) formé sur la face interne du col du flacon rigide (1 ) lorsque la pompe est dans la position de fonctionnement représentée sur la Figure 6. Dans cette position, la pompe (2) prend appui sur la bague (4).  The skirt (8) of the pump (2) is capable of coming into contact, by the edge (9) of its base, with the shoulder (10) formed on the internal face of the neck of the rigid bottle (1) when the pump is in the operating position shown in Figure 6. In this position, the pump (2) bears on the ring (4).
Dans la position de stockage représentée sur la Figure 1 , un anneau (1 1 ) est intercalé entre la pompe (2) et le col du flacon (1 ) pour maintenir le bord (9) de la jupe (8) de la pompe à une distance déterminée de l'épaulement (10). Cet anneau entoure la base de la jupe (8) de la pompe et empêche celle-ci d'être positionnée pour pouvoir être activée. Cet anneau (1 1 ) est amovible et peut être enlevé en tirant sur une languette (12), représentée sur les Figures 2 et 3, faisant saillie en surface du flacon (1 ), permettant d'arracher l'anneau réalisé en matière plastique telle que polyéthylène. Comme le montre la Figure 3, l'anneau a une section en U dont les deux branches s'appliquent contre les faces externe et interne de la partie inférieure de la jupe (8) de la pompe. La base (1 1 a) reliant les deux branches de l'anneau (1 1 ) est frangible et peut se rompre lorsque l'utilisateur tire sur la languette (12). In the storage position shown in FIG. 1, a ring (1 1) is interposed between the pump (2) and the neck of the bottle (1) to maintain the edge (9) of the skirt (8) of the pump. a determined distance from the shoulder (10). This ring surrounds the base of the skirt (8) of the pump and prevents it from being positioned to be activated. This ring (1 1) is removable and can be removed by pulling on a tab (12), shown in Figures 2 and 3, projecting from the surface of the bottle (1), for tearing the ring made of plastic such as polyethylene. As shown in Figure 3, the ring has a U-section whose two branches are applied against the outer and inner faces of the lower portion of the skirt (8) of the pump. The base (1 1 a) connecting the two branches of the ring (1 1) is frangible and can break when the user pulls on the tongue (12).
La base de la pompe (2) comporte un obturateur (13) dont le bord extérieur vient en contact étanche avec le bord interne de la bague (4). Ces deux pièces sont conformées pour assurer une bonne étanchéité et interdire tout passage de produit de la poche (5) vers la pompe (2) et tout passage de gaz de l'extérieur par la pompe vers la poche, comme le montre plus précisément la Figure 4. Des ouvertures (14) sont formées dans la base de la pompe pour laisser passer le produit sortant de la poche (5) quand le poussoir (3) est actionné, la pompe étant en position de fonctionnement, mais dans la position représentée sur la Figure 1 , l'anneau (1 1 ) étant en place et la pompe (2) se trouvant en position relevée, le circuit de passage du produit de la poche vers la pompe en passant par les ouvertures (14) se trouve fermé par le contact entre le bord interne de la bague (4) et l'obturateur (13).  The base of the pump (2) comprises a shutter (13) whose outer edge comes into sealing contact with the inner edge of the ring (4). These two parts are shaped to ensure a good seal and prohibit any product passage from the bag (5) to the pump (2) and any gas passage from the outside of the pump to the pocket, as more specifically shows the Figure 4. Openings (14) are formed in the base of the pump for passing the product exiting the bag (5) when the pusher (3) is actuated, the pump being in the operating position, but in the position shown in Figure 1, the ring (1 1) being in place and the pump (2) being in the raised position, the circuit for passing the product from the bag to the pump through the openings (14) is closed by the contact between the inner edge of the ring (4) and the shutter (13).
On voit que dans cette position relevée de la pompe (2), l'obturateur (13) forme une paroi isolante entre l'intérieur de la poche (5) contenant le produit à distribuer et la pompe. L'étanchéité est assurée par le contact entre le bord extérieur de l'obturateur (13) et le bord interne de la bague (4). Le produit contenu dans la poche se trouve donc parfaitement isolé de l'extérieur.  It can be seen that in this raised position of the pump (2), the shutter (13) forms an insulating wall between the inside of the pocket (5) containing the product to be dispensed and the pump. Sealing is ensured by the contact between the outer edge of the shutter (13) and the inner edge of the ring (4). The product contained in the pocket is therefore perfectly isolated from the outside.
Un capot (15) est prévu par-dessus le poussoir (3) pour fermer l'ensemble. A cover (15) is provided over the pusher (3) to close the assembly.
La Figure 5 représente le détail d'une variante de l'obturateur (13) en position de fermeture par contact étanche avec la bague (4). La face inférieure de l'obturateur (13) est revêtue d'un opercule (16), réalisé de préférence sous la forme d'un film en même matière que la poche (5). On évite ainsi toute discontinuité de matière entre la poche (5) et l'obturateur (13) et le produit contenu dans la poche n'est en contact qu'avec une seule matière. Figure 5 shows the detail of a variant of the shutter (13) in the closed position by sealing contact with the ring (4). The underside of the shutter (13) is coated with a cover (16), preferably in the form of a film of the same material as the pocket (5). This avoids any discontinuity of material between the bag (5) and the shutter (13) and the product contained in the bag is in contact with only one material.
Lorsque l'anneau (1 1 ) est enlevé par l'utilisateur en arrachant la languette (12), la pompe (2) peut être mise dans sa position définitive en la poussant de telle sorte que le bord (9) de la jupe (8) vienne en contact avec l'épaulement (10) formé dans la paroi du flacon (1 ) et que la base de la pompe vienne prendre appui sur la bague (4), dans la position représentée sur la Figure 6.  When the ring (1 1) is removed by the user by tearing the tongue (12), the pump (2) can be put in its final position by pushing it so that the edge (9) of the skirt ( 8) comes into contact with the shoulder (10) formed in the wall of the bottle (1) and that the base of the pump bears on the ring (4), in the position shown in Figure 6.
Comme le montre la Figure 7, dans cette position le bord inférieur du capot protecteur (15) vient en contact avec le bord supérieur du col du flacon (1 ).  As shown in Figure 7, in this position the lower edge of the protective cover (15) comes into contact with the upper edge of the vial neck (1).
Dans cette position, l'obturateur (13) est écarté de la bague (4) supportant la pompe et pénètre dans la poche (5), libérant ainsi les ouvertures (14) pour le passage du produit de la poche vers la pompe lorsque le poussoir (3) est actionné, comme représenté plus en détail sur la Figure 8.  In this position, the shutter (13) is spaced from the ring (4) supporting the pump and enters the pocket (5), thus releasing the openings (14) for the passage of the product from the bag to the pump when the pushbutton (3) is actuated, as shown in more detail in FIG.
Sur la variante de réalisation de l'invention représentée sur la Figure 9, et plus en détail sur la Figure 10, l'élément amovible est constitué par un anneau simple (17) comportant une amorce (12) pour son arrachage. Dans la position représentée sur la Figure 9, la pompe est soulevée par l'intermédiaire de l'anneau (17) par rapport à sa position définitive de fonctionnement.  In the variant embodiment of the invention shown in FIG. 9, and in more detail in FIG. 10, the removable element is constituted by a simple ring (17) comprising a primer (12) for its tearing. In the position shown in FIG. 9, the pump is raised via the ring (17) with respect to its final operating position.
Lorsque cet anneau (17) est intégralement enlevé par l'utilisateur lors de la première utilisation, aucun obstacle ne subsiste sous la base de la jupe (8) de la pompe, qui peut être mise en place, libérant l'obturateur et le passage de la poche vers la pompe.  When this ring (17) is completely removed by the user during the first use, no obstacle remains under the base of the skirt (8) of the pump, which can be put in place, releasing the shutter and the passage from the pocket to the pump.
