Description

CONDITIONNEMENT RECHARGEABLE ET SA CARTOUCHE RECHARGEABLE PACKAGING AND ITS CARTRIDGE
La présente invention concerne l'industrie du conditionnement en pot de substances fluides, notamment cosmétiques, pharmaceutiques, d'hygiène ou d'entretien ménager.The present invention relates to the packaging industry for jars of fluid substances, in particular cosmetics, pharmaceuticals, hygiene or household maintenance.
Le conditionnement en pot de telles substances est pratique mais le prélèvement direct dans le pot avec le doigt ou un instrument est source de souillure et la large ouverture facilite la pollution, le dessèchement et l'oxydation par l'exposition à l'air lors de chaque prélèvement. On a donc eu recours à des conditionnements en vase clos avec dispositif distributeur à pompe ou sous pression pour pallier ces inconvénients. On a proposé divers conditionnements de ce genre dans les documents WO-A-93 25447, EP-A-0 526 811 ou US-A-4 872 596. Mais ces conditionnements sont relativement plus onéreux et souvent peu esthétiques, surtout si, pour en limiter le coût, on utilise des matériaux bon marché. Or, plus particuliè¬ rement pour des produits cosmétiques ou d'hygiène appelés à rester visibles dans les salles de bains ou sur des coiffeuses, on recherche un aspect agréable, non dépréciatif du produit conditionné qui est souvent d'un prix relativement élevé.The packaging in jar of such substances is practical but the direct sampling in the jar with the finger or an instrument is a source of soiling and the wide opening facilitates pollution, drying and oxidation by exposure to air during each sample. We therefore used closed containers with a pump or pressurized distributor device to overcome these drawbacks. Various such packaging has been proposed in documents WO-A-93 25447, EP-A-0 526 811 or US-A-4 872 596. However, these packaging are relatively more expensive and often unsightly, especially if, for to limit the cost, we use cheap materials. However, more particularly for cosmetic or hygienic products intended to remain visible in the bathrooms or on dressing tables, a pleasant appearance, not depreciating of the packaged product is sought, which is often of relatively high price.
Afin de répondre au désir des consommateurs d'une bonne, voire luxueuse, présentation d'un prix acceptable, on a envisagé d'utiliser le même emballage extérieur pour un nombre indéterminé de contenances renouvelées en cartouches interchangeables munies chacune d'un dispositif distributeur (cf. US-A-5 190 191). Le but de l'invention est d'éviter toute manoeuvre fastidieuse, délicate, ou salissante pour la recharge de l'emballage ainsi que l'usure ou le bouchage d'un dispositif distributeur réutilisé.In order to meet consumers' desire for a good, even luxurious, presentation of an acceptable price, it has been envisaged to use the same outer packaging for an unspecified number of renewed capacities in interchangeable cartridges each provided with a dispensing device ( cf. US-A-5 190 191). The object of the invention is to avoid any tedious, delicate or messy operation for recharging the packaging as well as the wear or clogging of a reused dispensing device.
L'invention a pour objet un conditionnement rechargeable pour la distribution de substances fluides comprenant un boîtier en forme de cloche fermée par un socle amovible, traversé par un poussoir manuel prisonnier, et laissant passage à une buse de distribution ; l'intérieur du boîtier logeant une cartouche interchangeable comprenant un récipient en forme de pot retourné, à fond mobile, dont la face supérieure porte un organe distributeur associé à une buse de distribution ; le récipient et le boîtier présentant des moyens coopérants de positionnement et de calage de la cartouche dans le boîtier, l'organe distributeur étant prolongé par une tige d'actionnement dont l'extrémité libre présente des moyens de raccordement temporaire avec des moyens complémentaires de l'extrémité libre du poussoir,The subject of the invention is a refillable packaging for the distribution of fluid substances comprising a bell-shaped housing closed by a removable base, crossed by a captive manual pusher, and allowing passage to a dispensing nozzle; the inside of the housing housing an interchangeable cartridge comprising a container in the form of an inverted jar, with a movable bottom, the upper face of which carries a dispensing member associated with a dispensing nozzle; the container and the housing having cooperating means for positioning and wedging the cartridge in the housing, the dispensing member being extended by an actuating rod whose free end has temporary connection means with means complementary to the free end of the pusher,
- caractérisé en ce que la cartouche comporte une lame de ressort, extérieure à l'organe distributeur, l'extrémité libre externe de la tige d'actionnement présente un renflement, raccordé au poussoir par lequel la lame de ressort exerce une traction sur la tige d'actionnement, tandis que l'extrémité libre interne du poussoir présente face à la cartouche une partie inclinée en forme de came qui coopère avec la lame de ressort, lors de l'introduction d'une cartouche dans le boîtier, pour dégager l'extrémité libre de la tige d'actionnement et permettre l'insertion et la retenue de son renflement terminal dans une rainure à section en T, parallèle à l'axe de la cartouche et débouchant à ses extrémités ainsi que latéralement.- characterized in that the cartridge comprises a spring leaf, external to the dispensing member, the free external end of the actuating rod has a bulge, connected to the plunger by which the spring leaf exerts traction on the rod actuation, while the internal free end of the pusher has a cam-shaped inclined part facing the cartridge which cooperates with the leaf spring, when a cartridge is introduced into the housing, to release the free end of the actuating rod and allow the insertion and retention of its terminal bulge in a T-section groove, parallel to the axis of the cartridge and opening at its ends as well as laterally.
L'organe distributeur porté par le récipient peut être une pompe aspirante-refoulante à clapets anti-retour, avec l'avantage d'une distribution dosée, ou bien un obturateur du type tiroir ou valve. En ce cas le fond mobile du récipient est constamment sollicité par un ressort de pression prenant appui contre le socle du boîtier.The dispenser member carried by the container can be a suction-discharge pump with non-return valves, with the advantage of metered distribution, or a shutter of the drawer or valve type. In this case the movable bottom of the container is constantly stressed by a pressure spring bearing against the base of the housing.
En pratique, il est avantageux que les lèvres de la rainure soient élastiquement déformables et assurent l'encliquetage du renflement de la tige dans la rainure du poussoir par pression du doigt de l'utilisateur sur le poussoir lors de la mise en service d'une cartouche.In practice, it is advantageous for the lips of the groove to be elastically deformable and to ensure that the swelling of the rod is snapped into the groove of the pusher by pressing the user's finger on the pusher during the commissioning of a cartridge.
Le ressort peut être constitué par une lame flexible en arc de cercle dont les extrémités libres s'arcboutent contre des butées parallèles issues de la paroi supérieure du récipient et la partie centrale de la lame flexible est traversée librement par la tige d'actionnement.The spring can be constituted by a flexible blade in an arc of a circle whose free ends are curved against parallel stops coming from the upper wall of the container and the central part of the flexible blade is freely traversed by the actuating rod.
En variante, le ressort peut être constitué par une lame flexible en arc de cercle dont les extrémités libres s'arcboutent contre des butées parallèles solidaires du poussoir et la partie centrale de la lame flexible est fixée à un support issu de la paroi supérieure du récipient.As a variant, the spring may be constituted by a flexible blade in an arc of a circle whose free ends are curved against parallel stops integral with the pusher and the central part of the flexible blade is fixed to a support coming from the upper wall of the container. .
Le ressort peut aussi être constitué par une paroi en arc de cercle du poussoir à l'opposé de la face d'appui du doigt de l'utilisateur, la partie centrale de la paroi en arc de cercle butant contre une potence issue de la paroi supérieure du récipient. L'invention a également pour objet une cartouche interchangeable pour le conditionnement objet de l'invention, caractérisée en ce qu'elle comprend un récipient, à fond mobile, dont la face supérieure est solidaire d'un organe distributeur associé à une buse de distribution et présentant une tige d'actionnement automatiquement raccordable à un poussoir prisonnier d'un boîtier recevant la cartouche.The spring may also be constituted by a wall in an arc of a circle of the pusher opposite to the bearing face of the user's finger, the central part of the wall in an arc of a circle abutting against a stem coming from the wall. top of the container. The invention also relates to an interchangeable cartridge for the packaging object of the invention, characterized in that it comprises a container, with movable bottom, the upper face of which is integral with a dispensing member associated with a dispensing nozzle and having an actuating rod automatically connectable to a pusher trapped in a housing receiving the cartridge.
Selon un mode de réalisation avantageux, l'organe distributeur comporte une tige d'actionnement dont l'extrémité libre est protégée par une lame de ressort en arc de cercle dont la partie centrale présente une ouverture de libre passage de la tige.According to an advantageous embodiment, the dispensing member comprises an actuating rod whose free end is protected by a leaf spring in an arc of a circle whose central part has a free passage opening of the rod.

Le piston 16 de la pompe est prolongé par une tige d'actionnement 17 traversant une lame de ressort 19 en arc de cercle dont les extrémités libres s'arcboutent contre des butées parallèles 20, 21 et 20' , 21 ' issues de la paroi supérieure du récipient. La partie centrale de la lame de ressort 19 présente une ouverture 22 pour le passage libre de la tige 17 du piston. Cette tige 17 se termine par un renflement 18 par lequel la lame de ressort 19 exerce sur elle une traction, par l'intermédiaire du poussoir 2 à l'intérieur du boîtier alors que le renflement 18 est prisonnier dans une rainure axiale en T 23 à lèvres élastiquement déformables creusée dans l'extrémité libre du poussoir 2, (figures 2, 3 et 4).The cartridge 4 comprises a container 6 in the form of an inverted pot, the open bottom of which is closed by a free piston 7 pierced in its center with an orifice 8 for filling the container, closed by a plug 9. The side face of the container has a lug 10 for orienting the cartridge in the housing which cooperates with a longitudinal groove 11 hollowed out in the internal lateral wall of the housing in order to present the cartridge properly when it is introduced into the housing. An annular rib 12 from the base 5 prevents the piston 7 from escaping accidentally. The upper wall of the container 6 is pierced with an orifice 13 communicating with the interior of a pump cylinder 14, integral with the upper wall of the container, under the control of a non-return ball valve 15. The piston 16 of the pump is extended by an actuating rod 17 passing through a spring leaf 19 in an arc, the free ends of which are curved against parallel stops 20, 21 and 20 ′, 21 ′ coming from the upper wall of the container . The central part of the leaf spring 19 has an opening 22 for the free passage of the rod 17 of the piston. This rod 17 ends with a bulge 18 by which the spring leaf 19 exerts traction on it, by means of the pusher 2 inside the housing while the bulge 18 is trapped in an axial T-groove 23 at lips elastically deformable dug in the free end of the pusher 2, (Figures 2, 3 and 4).
Le poussoir 2 présente deux languettes latérales flexibles 24, 24' avec ergots extérieurs 25, 25' qui retiennent le poussoir prisonnier dans une fente 27 de la paroi du boîtier, en coopération avec un bourrelet 26 entourant l'extrémité externe du poussoir, mais libre de débattre de part et d'autre de la paroi latérale du boîtier qu'il traverse. La face inférieure du poussoir vis à vis de la cartouche se termine par une partie inclinée 28 qui agit comme une came lors de l'introduction d'une cartouche dans le boîtier pour refouler la lame de ressort 19 et le poussoir, s'ils ne se trouvent pas en bonne position, afin de permettre au renflement 18 de l'extrémité de la tige de piston 17 de pénétrer dans la rainure en T 23 de l'extrémité du poussoir.The pusher 2 has two flexible lateral tabs 24, 24 'with external pins 25, 25' which hold the pusher captive in a slot 27 in the wall of the housing, in cooperation with a bead 26 surrounding the external end of the pusher, but free to debate on either side of the side wall of the housing it passes through. The underside of the pusher with respect to the cartridge ends in an inclined portion 28 which acts like a cam when a cartridge is introduced into the housing to push back the spring leaf 19 and the pusher, if they do not are not in the correct position, in order to allow the bulge 18 of the end of the piston rod 17 to penetrate the T-groove 23 of the end of the pusher.
Le cylindre 14 communique également par un orifice 29 avec une buse 30 de distribution renfermant un clapet plat anti-retour 31. Cette buse 30 de forme tronconique s'insère dans l'orifice de forme complémentaire 3 de la paroi supérieure du boîtier 1 lors de la mise en place de la cartouche 4 dans le boîtier.The cylinder 14 also communicates through an orifice 29 with a dispensing nozzle 30 containing a flat non-return valve 31. This frustoconical nozzle 30 is inserted into the complementary shaped orifice 3 of the upper wall of the housing 1 during placing the cartridge 4 in the housing.
La tige d'actionnement du dispositif distributeur est libre, sauf les frottements, de se déplacer lorsqu'elle n'est pas en prise avec le poussoir, ce qui est le cas pour une cartouche de recharge tant qu'elle n'est pas engagée dans le boîtier. Afin d'éviter toute manoeuvre inopportune de l'organe de distributeur d'une cartouche hors du boîtier, la longueur de la tige d'action¬ nement est telle qu'en fin de course d'enfoncement, le renflement terminal de cette tige ne fait pas saillie hors du ressort librement arqué. Ainsi, il n'est pas possible à un utilisateur de le saisir et d'actionner la tige par inadvertance, ce qui apporte une garantie de non-utilisation d'une cartouche de recharge.The actuating rod of the dispensing device is free, except for friction, to move when it is not in engagement with the pusher, which is the case for a refill cartridge as long as it is not engaged in the housing. In order to avoid any untimely maneuvering of the dispenser member of a cartridge outside the housing, the length of the action rod is such that at the end of the driving stroke, the terminal bulge of this rod does not does not protrude out of the freely arched spring. Thus, it is not possible for a user to grasp it and activate the rod inadvertently, which provides a guarantee of non-use of a refill cartridge.
Lorsqu'on introduit une cartouche dans le boîtier, le poussoir est repoussé, s'il est enfoncé, par sa partie inclinée 28 qui vient porter et glisser contre la tranche supérieure externe du ressort 19, le renflement terminal 18 de la tige restant protégé par le ressort. Il suffit alors à l'utilisateur d'appuyer sur le poussoir pour comprimer le ressort, dégager l'extrémité de la tige d'actionnement et forcer son renflement terminal à écarter élastiquement les lèvres de la rainure 23 pour venir s'encliqueter derrière elles. Le poussoir est alors en prise avec la tige et le conditionnement est fonctionnel.When a cartridge is introduced into the housing, the pusher is pushed back, if it is depressed, by its inclined part 28 which comes to bear and slide against the upper external edge of the spring 19, the terminal bulge 18 of the rod remaining protected by the spring. The user then just has to press the plunger to compress the spring, disengage the end of the actuating rod and force its terminal bulge to elastically spread the lips of the groove 23 to snap behind they. The pusher is then engaged with the rod and the packaging is functional.
Lorsqu'on retire une cartouche du boîtier, par translation axiale après avoir dévissé le socle 5, le renflement terminal de la tige d'actionnement de l'organe distributeur glisse librement le long de la rainure 23 jusqu'à dégagement et décompression du ressort. Dans la cartouche ainsi retirée, la tige d'actionnement reste en position de fin de course de repos, et fait saillie hors du ressort, ce qui constitue un témoin d'utilisation de la cartouche. Si on réintroduit une telle cartouche dans le boîtier, le poussoir sorti, sinon repoussé par sa partie inclinée, présente l'extrémité ouverte de sa rainure en position de réception du renflement terminal de la tige qui y coulisse librement lorsqu'on enfonce la cartouche dans le boîtier, guidée axialement par son ergot d'orientation 10 dans la rainure 11 longitudi- nalement coopérante du boîtier. Dans la première variante représentée sur les figures 5 et 6 on retrouve les mêmes éléments dans la même disposition, mais la pompe est remplacée par un distributeur à tiroir 32, dont le fond du cylindre 14a est percé d'un orifice 33 d'aération qui permet le libre débattement du tiroir commandé par une tige 17a identique à la tige de piston de l'exemple précédent. Un ressort conique 34 de compression prend appui sur le socle 5a pour exercer constamment une pression sur le piston libre 7a obturant le fond du récipient 6a dans lequel il est centré par un téton 35 axial issu du socle 5a. Ce mode de réalisation ne nécessite pas de clapets anti-retour et la distribution du produit conditionné est continue tant que l'utilisateur appuie sur le poussoir 2a.When a cartridge is removed from the housing, by axial translation after having unscrewed the base 5, the terminal bulge of the actuating rod of the dispensing member slides freely along the groove 23 until the spring is released and decompressed. In the cartridge thus removed, the actuating rod remains in the rest end-of-travel position, and projects out of the spring, which constitutes a witness to the use of the cartridge. If such a cartridge is reintroduced into the housing, the pusher which is pulled out, if not pushed back by its inclined part, has the open end of its groove in the position for receiving the terminal bulge of the rod which slides there freely when the cartridge is pushed into the housing, axially guided by its orientation lug 10 in the longitudinally cooperating groove 11 of the housing. In the first variant shown in Figures 5 and 6 we find the same elements in the same arrangement, but the pump is replaced by a spool valve 32, the bottom of the cylinder 14a is pierced with an orifice 33 for ventilation which allows the free movement of the drawer controlled by a rod 17a identical to the piston rod of the previous example. A conical compression spring 34 bears on the base 5a in order to constantly exert pressure on the free piston 7a closing the bottom of the container 6a in which it is centered by an axial stud 35 coming from the base 5a. This embodiment does not require non-return valves and the distribution of the packaged product is continuous as long as the user presses the pusher 2a.
Dans la deuxième variante représentée sur les figures 7 et 8, on retrouve une cartouche 4b surmontée d'une pompe 14b à piston libre prolongé par une tige d'actionnement 17b. Un clapet 15b contrôle l'aspira¬ tion de la pompe et la buse 30b son échappement. La buse, en matériau élastique, présente deux lumières en arc de cercle 33b qui, au repos, sont obturées par la tranche du canal d'évacuation 29b de la pompe (figure 7) et qui s'écartent élastiquement pour laisser échapper le produit à distribuer sous la pression exercée par la pompe (figure 9). La cartouche est insérée dans un socle 5b sur lequel est emboîté, encliqueté, un couvercle lb guidé, orienté, par trois ergots 10b. Une potence 34b issue de la paroi supérieure de la cartouche 4b est percée d'un orifice dans lequel vient s'encliqueter un ergot central 35b d'une lame de ressort 19b en arc de cercle. Un poussoir 2b en forme de T est prisonnier, libre de débattre axialement, dans une ouverture latérale du couvercle lb. Les branches latérales 20b,20'b du T constituent des arcs- boutants pour les extrémités libres du ressort 19b. Un téton tubulaire axial 36b du poussoir emprisonne dans une fente l'extrémité renflée de la tige d'actionnement 17b de la pompe, comme dans les modes de réalisation précédents. Le poussoir 2b est retenu dans le couvercle lb, libre de débattre, par un ergot 26b coopérant avec une butée 37b issue du fond du couvercle lb.In the second variant shown in Figures 7 and 8, there is a cartridge 4b surmounted by a pump 14b with free piston extended by an actuating rod 17b. A valve 15b controls the suction of the pump and the nozzle 30b its exhaust. The nozzle, made of elastic material, has two openings in a circular arc 33b which, at rest, are closed by the edge of the discharge channel 29b of the pump (FIG. 7) and which move away elastically to allow the product to escape. distribute under the pressure exerted by the pump (figure 9). The cartridge is inserted into a base 5b on which is fitted, snapped on, a cover 1b guided, oriented, by three lugs 10b. A bracket 34b coming from the upper wall of the cartridge 4b is pierced with an orifice in which a central lug 35b of a spring leaf 19b is latched in an arc of a circle. A T-shaped pusher 2b is trapped, free to debate axially, in a lateral opening of the cover lb. The lateral branches 20b, 20'b of the T constitute flying buttresses for the free ends of the spring 19b. An axial tubular stud 36b of the pusher traps in a slot the swollen end of the actuating rod 17b of the pump, as in the previous embodiments. The pusher 2b is retained in the cover lb, free to debate, by a lug 26b cooperating with a stop 37b coming from the bottom of the cover lb.
La troisième variante, représentée sur les figures 9 à 11 ne diffère de la deuxième variante représentée sur les figures 7 et 8 que par le fait que le ressort est constitué par une paroi terminale 19e, en arc de cercle au repos (figure 11), du poussoir 2c, à l'opposé de la face 38c offerte au doigt de l'utilisateur. Cette paroi 19c s'aplatit élastiquement contre la potence 34e lorsqu'on appuie sur le poussoir (figures 9 et 10).The third variant, shown in FIGS. 9 to 11, differs from the second variant shown in FIGS. 7 and 8 only by the fact that the spring consists of an end wall 19th, in an arc of a circle at rest (FIG. 11), pusher 2c, opposite the face 38c offered to the user's finger. This wall 19c is flattened elastically against the stem 34e when the pusher is pressed (Figures 9 and 10).
Dans cette variante, le poussoir peut être prisonnier du couvercle, comme dans la variante des figures 7 et 8, ou bien être solidaire de la cartouche 4c, le couvercle le présentant alors une échancrure 38c pour le passage du poussoir 2c, (figure 9). In this variant, the pusher can be trapped in the cover, as in the variant in FIGS. 7 and 8, or else be secured to the cartridge 4c, the cover then presenting it with a notch 38c for the passage of the pusher 2c (FIG. 9) .
