Description

La présente invention se rapporte à un ensemble de distribution comportant un récipient, destiné à contenir un produit liquide, gélifié ou pâteux, ainsi qu'à un procédé de fabrication de cet ensemble.The present invention relates to a dispensing assembly comprising a container, intended to contain a liquid, gelled or pasty product, as well as to a process for manufacturing this assembly.

Ce récipient est destiné, plus particulièrement, à contenir un produit cosmétique, pharmaceutique, ménager ou alimentaire, tel que par exemple un shampooing, un lait corporel, un antiseptique, un détergent ou encore de la moutarde.This container is intended, more particularly, to contain a cosmetic, pharmaceutical, household or food product, such as for example a shampoo, a body milk, an antiseptic, a detergent or even mustard.

Ce récipient se présente, notamment sous la forme d'un flacon comportant une tête de distribution intégrée. La tête de distribution, selon l'invention est généralement équipée d'un organe de distribution, tel qu'une pompe, escamotée dans le corps du récipient, contenant le produit.This container is, in particular in the form of a bottle having an integrated dispensing head. The dispensing head according to the invention is generally equipped with a dispensing member, such as a pump, retracted into the body of the container, containing the product.

On connaît, par exemple par le document WO-A-93/00 361, un récipient comportant un corps muni d'une tête de pulvérisation, escamotable dans le corps du récipient. La tête de pulvérisation est montée sur une zone du corps en forme de tronc de cône comportant une grande et une petite section, rentrant dans le corps du récipient en position de stockage à vide, notamment après l'épuisement du produit, de façon que le tronc de cône s'étend de sa grande section à sa petite section vers l'intérieur du récipient. Lors de l'utilisation, on tire le tronc de cône portant le bec verseur vers l'extérieur du corps ; le tronc de cône effectue ainsi une sorte de retroussement. Pendant la distribution du produit, le tronc de cône se trouve donc retroussé vers l'extérieur du récipient, et l'escamotage de la tête de distribution est réalisé en vue de réduire le volume du récipient, lorsque celui-ci est vide.Is known, for example from document WO-A-93/00 361, a container comprising a body provided with a spray head, retractable in the body of the container. The spray head is mounted on an area of the body in the form of a truncated cone comprising a large and a small section, entering the body of the container in the empty storage position, in particular after the product has been used up, so that the truncated cone extends from its large section to its small section towards the inside of the container. During use, the truncated cone carrying the pouring spout is pulled towards the outside of the body; the truncated cone thus performs a kind of rolling up. During the distribution of the product, the truncated cone is therefore turned up towards the outside of the container, and the retraction of the dispensing head is carried out in order to reduce the volume of the container, when the latter is empty.

La présente invention a pour objet un récipient distributeur qui, contrairement au récipient de l'art antérieur, est muni d'un organe de distribution solidaire d'un col en forme de tronc de cône escamoté non seulement pendant le transport mais aussi pendant l'utilisation. Ce tronc de cône s'étend vers l'extérieur du récipient lors du remplissage du récipient et lors du montage de l'organe de distribution sur le récipient. Le retroussement du tronc de cône vers l'intérieur du corps du récipient est réalisé avant la première utilisation du dispositif. Dans cette configuration retroussée, le récipient distributeur de l'invention a une forme particulièrement compacte, ce qui est avantageux, et permet la réduction du volume et des frais d'emballage et de stockage.The present invention relates to a dispensing container which, unlike the container of the prior art, is provided with a dispensing member secured to a neck in the form of a retracted cone not only during transport but also during use. This truncated cone extends towards outside the container when filling the container and when mounting the dispensing member on the container. The rolling up of the truncated cone towards the interior of the container body is carried out before the first use of the device. In this upturned configuration, the dispensing container of the invention has a particularly compact shape, which is advantageous, and allows the reduction of the volume and of the packaging and storage costs.

En plus des avantages mentionnés ci-dessus, le dispositif de l'invention présente un bel aspect esthétique.In addition to the advantages mentioned above, the device of the invention has a beautiful aesthetic appearance.

De façon plus précise, l'invention se rapporte à un ensemble de distribution de produit comprenant un récipient en forme de flacon ayant un corps à fond fermé ; un col en tronc de cône ayant une grande section et une petite section, la grande section étant rattachée à une extrémité opposée au fond du récipient et la petite section étant rattachée à un goulot ; un organe de distribution monté sur le goulot du récipient communiquant avec un orifice de distribution ; des moyens d'actionnement de l'organe de distribution pour provoquer la distribution d'une dose de produit contenu dans le récipient, le goulot s'étendant vers l'extérieur du récipient et le tronc de cône s'étendant vers l'intérieur du corps du récipient, de sorte que le goulot et au moins une partie de l'organe de distribution sont logés à l'intérieur du tronc de cône, pendant l'utilisation de l'ensemble.More specifically, the invention relates to a product dispensing assembly comprising a container in the form of a bottle having a body with a closed bottom; a frustoconical neck having a large section and a small section, the large section being attached to an end opposite the bottom of the container and the small section being attached to a neck; a dispensing member mounted on the neck of the container communicating with a dispensing orifice; means for actuating the dispensing member to cause the dispensing of a dose of product contained in the container, the neck extending towards the outside of the container and the truncated cone extending towards the inside of the container. container body, so that the neck and at least part of the dispensing member are housed inside the truncated cone, during use of the assembly.

Avantageusement, l'organe de distribution est une pompe de distribution à tige d'actionnement émergente ayant une course de manoeuvre déterminée. La pompe est fixée au goulot par un élément de fixation, par exemple à l'aide d'une bague vissée ou claquée ayant une hauteur déterminée. Avantageusement, le col a une hauteur sensiblement égale à celle de la course de la pompe augmentée de la hauteur de l'élément de fixation. La pompe peut être munie d'un tube plongeur s'étendant jusqu'au fond du récipient.Advantageously, the dispensing member is a dispensing pump with an emerging actuating rod having a determined operating stroke. The pump is fixed to the neck by a fixing element, for example using a screwed or slammed ring having a determined height. Advantageously, the neck has a height substantially equal to that of the stroke of the pump increased by the height of the fixing element. The pump can be fitted with a dip tube extending to the bottom of the container.

De préférence, la tige de pompe est raccordée à une tête de distribution qui constitue les moyens d'actionnement de la pompe.Preferably, the pump rod is connected to a dispensing head which constitutes the means for actuating the pump.

Selon une forme d'exécution particulière de l'invention, le corps de récipient a une forme de segment de calotte sphérique, et la tête de distribution a, dans ce cas, une forme de segment sphérique complémentaire au segment du corps, de sorte que la tête de distribution et le corps du récipient s'inscrivent dans une sphère, formant ainsi un ensemble compact. Avantageusement, la tête de distribution et le corps du récipient se trouvent à une distance égale ou supérieure à celle de la course de la tige de pompe. ll est bien entendu, que le corps peut avoir toute forme imaginable, par exemple la forme d'un cylindre, d'un cube, etc.According to a particular embodiment of the invention, the container body has a shape of a spherical cap segment, and the dispensing head has, in this case, a shape of a spherical segment complementary to the segment of the body, so that the dispensing head and the container body are in a sphere, thus forming a compact unit. Advantageously, the dispensing head and the body of the container are at a distance equal to or greater than that of the stroke of the pump rod. It is understood, of course, that the body can have any imaginable shape, for example the shape of a cylinder, a cube, etc.

Avantageusement, la tête de distribution peut comporter un cache cylindrique dont la hauteur correspond sensiblement à la distance de la course de la pompe, lorsqu'elle est actionnée, ce cache s'étendant en direction de la pompe de distribution. Ainsi, le goulot et le col du récipient, la pompe et la bague de fixation restent invisibles de l'extérieur.Advantageously, the dispensing head may include a cylindrical cover whose height corresponds substantially to the distance of the stroke of the pump, when it is actuated, this cover extending in the direction of the distribution pump. Thus, the neck and the neck of the container, the pump and the fixing ring remain invisible from the outside.

Afin de faciliter la distribution du produit et pour éviter des salissures du corps, la tête de distribution peut comporter un bec distributeur muni de l'orifice de distribution, ce bec s'étendant radialement par rapport à un axe du corps, notamment de symétrie. La tête de distribution est traversée, avantageusement, par un canal de distribution reliant l'orifice de distribution à la tige de pompe.In order to facilitate the distribution of the product and to avoid soiling of the body, the dispensing head may include a dispensing spout provided with the dispensing orifice, this spout extending radially with respect to an axis of the body, in particular of symmetry. The dispensing head is advantageously traversed by a dispensing channel connecting the dispensing orifice to the pump rod.

De préférence, le tronc de cône s'étend de sa grande section à sa petite section vers l'intérieur du corps du récipient.Preferably, the truncated cone extends from its large section to its small section towards the inside of the body of the container.

La présente invention se rapporte également à un procédé de fabrication et de conditionnement de l'ensemble décrit ci-dessus, consistant à effectuer successivement les étapes suivantes :

  • soufflage d'un récipient ayant un corps à fond fermé comportant un col en tronc de cône ayant une grande section et une petite section, la grande section étant rattachée à l'extrémité opposée au fond du récipient et la petite section étant rattachée à un goulot, ce cône s'étendant vers l'extérieur du corps du récipient et étant prolongé par le goulot, du côté de sa petite section ;
  • remplissage du récipient d'une quantité de produit appropriée ;
  • fixation de l'organe de distribution sur le goulot du récipient;
  • montage des moyens d'actionnement de l'organe de distribution, et
  • enfoncement, par pression sur les moyens d'actionnement, du col vers l'intérieur du récipient, de façon à placer le goulot et au moins une partie de l'organe de distribution à l'intérieur du tronc de cône.
The present invention also relates to a method of manufacturing and packaging the assembly described above, consisting in successively carrying out the following steps:
  • blowing a container having a closed bottom body comprising a frustoconical neck having a large section and a small section, the large section being attached to the end opposite to the bottom of the container and the small section being attached to a neck , this cone extending towards the outside of the body of the container and being extended by the neck, on the side of its small section;
  • filling the container with an appropriate quantity of product;
  • fixing the dispensing member to the neck of the container;
  • mounting of the actuating means of the distribution member, and
  • depression, by pressure on the actuating means, of the neck towards the interior of the container, so as to place the neck and at least part of the dispensing member inside the truncated cone.

Par cette dernière opération, on obtient donc un retroussement du col d'une position extérieure vers une position intérieure, par rapport au corps du récipient.By this last operation, the neck is therefore rolled up from an external position to an internal position, relative to the body of the container.

Avantageusement, le corps du récipient est obtenu par soufflage d'un matériau thermoplastique tel que le polypropylène ou le polyéthylène, les moyens d'actionnement étant moulés, par exemple, en polypropylène.Advantageously, the container body is obtained by blowing a thermoplastic material such as polypropylene or polyethylene, the actuating means being molded, for example, from polypropylene.

Pour mieux faire comprendre la présente invention, on va décrire maintenant, à titre d'exemple purement illustratif et nullement limitatif, un mode de réalisation de l'ensemble de distribution conforme à l'invention, représenté sur les dessins annexés.To better understand the present invention, we will now describe, by way of purely illustrative and in no way limitative, an embodiment of the distribution assembly according to the invention, shown in the accompanying drawings.

La figure 1 représente une coupe axiale du récipient distributeur, selon l'invention, en position d'utilisation.Figure 1 shows an axial section of the dispensing container, according to the invention, in the position of use.

La figure 2 représente une coupe axiale du récipient de la figure 1, pendant son conditionnement.2 shows an axial section of the container of Figure 1, during its packaging.

En référence à la figure 1, on peut voir un ensemble de distribution comportant un corps de récipient 2 surmontée d'une tête de distribution 9 constituant des moyens d'actionnement. Le récipient 2 est pourvu d'un axe de symétrie A. Le corps du récipient 2 comprend un fond fermé 4, une paroi latérale périphérique 21 raccordée au fond et un plateau annulaire 11 qui forme une extrémité supérieure du récipient qui est raccordé à la paroi latérale. Le récipient 2 et la tête 9 s'inscrivent dans une sphère S de la manière suivante. Le corps du récipient a la forme d'un segment de sphère dont une première coupe S1 définit le fond 4. Une seconde coupe S2, parallèle à la première, définit le plateau annulaire supérieur 11. La paroi périphérique latérale 21 qui fait partie de la surface de la sphère S relie le fond 4 au plateau 11, par un bord externe circulaire 31.Referring to Figure 1, we can see a dispensing assembly comprising a container body 2 surmounted by a dispensing head 9 constituting actuating means. The container 2 is provided with an axis of symmetry A. The body of the container 2 comprises a closed bottom 4, a peripheral side wall 21 connected to the bottom and an annular plate 11 which forms an upper end of the container which is connected to the wall lateral. The container 2 and the head 9 are inscribed in a sphere S in the following manner. The body of the container has the shape of a sphere segment of which a first section S 1 defines the bottom 4. A second section S 2 , parallel to the first, defines the upper annular plate 11. The lateral peripheral wall 21 which forms part of the surface of the sphere S connects the bottom 4 to the plate 11, by a circular external edge 31.

La tête de distribution 9 présente une forme de calotte ou segment de sphère, complémentaire à la forme du corps du récipient 2 et chapeautant celui-ci ; ainsi, la surface externe de la tête fait partie, également, de la surface de la sphère S. Elle comprend une base circulaire 98 située à la distance h du plateau 11.The dispensing head 9 has a shape of a cap or segment of a sphere, complementary to the shape of the body of the container 2 and covering the latter; thus, the external surface of the head also forms part of the surface of the sphere S. It comprises a circular base 98 situated at the distance h from the plate 11.

Une troisième coupe S3 de la sphère S, parallèle aux deux premières coupes S1 et S2, définit la base 98 circulaire de la tête de distribution 9. La tête de distribution comporte, en outre, un bec 96 s'étendant radialement au delà de la base 98. Ce bec a une orientation perpendiculaire à l'axe A. Il est traversé par un canal de distribution coudé 91 se terminant à l'extérieur par un orifice de distribution 92. Le canal 91 a un branche 93 intérieure, orientée suivant l'axe A. Cette branche 93 se termine par un embout central creux 95 dans lequel est engagée à force la tige 10 de la pompe 7.A third section S 3 of the sphere S, parallel to the first two sections S 1 and S 2 , defines the circular base 98 of the dispensing head 9. The dispensing head further comprises a spout 96 extending radially to the beyond the base 98. This spout has an orientation perpendicular to the axis A. It is crossed by a bent distribution channel 91 ending outside by a distribution orifice 92. The channel 91 has an internal branch 93, oriented along the axis A. This branch 93 ends with a hollow central tip 95 in which the rod 10 of the pump 7 is forcibly engaged.

Le plateau 11 du récipient 2 présente un bord interne circulaire 32 de plus petit diamètre que le bord externe 31. A ce bord interne est raccordée la paroi tronconique d'un col 5 s'étendant vers l'intérieur du récipient, formant une cuvette de révolution en forme de tronc de cône. Ce tronc de cône, de hauteur D, est fermé par un fond circulaire 12, dont le diamètre est inférieur à celui du bord interne circulaire 31 du plateau 11. Le fond 12 est pourvu d'une ouverture 13, prolongée vers l'extérieur par un goulot cylindrique 6 de même diamètre que l'ouverture 13. Ce goulot 6 s'étend sensiblement jusqu'à la moitié de la hauteur D de la cuvette. Dans ce goulot est insérée une pompe 7, fixée au goulot 6 à l'aide une bague de fixation 8 de hauteur H. La pompe 7 comporte une tige d'actionnement et de distribution 10, dont la course d'actionnement est représentée par la référence h.The tray 11 of the container 2 has a circular internal edge 32 of smaller diameter than the external edge 31. To this internal edge is connected the frustoconical wall of a neck 5 extending towards the interior of the container, forming a bowl of revolution in the shape of a truncated cone. This trunk of cone, tall D, is closed by a circular bottom 12, the diameter of which is less than that of the circular internal edge 31 of the plate 11. The bottom 12 is provided with an opening 13, extended towards the outside by a cylindrical neck 6 of the same diameter that the opening 13. This neck 6 extends substantially up to half the height D of the bowl. In this neck is inserted a pump 7, fixed to the neck 6 using a fixing ring 8 of height H. The pump 7 comprises an actuation and distribution rod 10, the actuation stroke of which is represented by reference h.

En appuyant sur la tête de distribution 9 et en enfonçant celle-ci de la distance h suivant la direction de l'axe A, on sollicite la tige d'actionnement 10 provoquant la distribution d'une dose de produit.By pressing the dispensing head 9 and pushing it by the distance h in the direction of the axis A, the actuating rod 10 is urged causing the dispensing of a dose of product.

Avantageusement, la hauteur du tronc de cône D est sensiblement égale à la course h de la pompe, augmentée de la hauteur H de la bague de fixation 8 de la pompe. Ici, la fixation a été effectuée par vissage de la bague 8 sur le goulot 6, la bague comportant un filetage interne 81 coopérant avec un filetage externe 61 du goulot. Il est possible, également, d'effectuer la fixation de la bague sur le goulot par claquage, ou par tout autre moyen convenable.Advantageously, the height of the truncated cone D is substantially equal to the stroke h of the pump, increased by the height H of the fixing ring 8 of the pump. Here, the fixing was carried out by screwing the ring 8 on the neck 6, the ring comprising an internal thread 81 cooperating with an external thread 61 of the neck. It is also possible to fix the ring on the neck by snap-fastening, or by any other suitable means.

Intérieurement, la tête de distribution 9 comporte, en outre, une jupe cylindrique 94 formant cache pour la pompe 7 et la tige d'actionnement 10. Le diamètre interne de ce cache est supérieur à celui de la pompe 7, et inférieur à celui du bord 32. Son hauteur est au moins égale à la course h de la pompe.Internally, the dispensing head 9 further comprises a cylindrical skirt 94 forming a cover for the pump 7 and the actuating rod 10. The internal diameter of this cover is greater than that of the pump 7, and less than that of the edge 32. Its height is at least equal to the stroke h of the pump.

Le conditionnement de cet ensemble de distribution sera illustré plus en détail, ci-après, avec référence à la figure 2.The packaging of this dispensing assembly will be illustrated in more detail below, with reference to FIG. 2.

Comme montré sur cette figure, on utilise un récipient 2 comportant un col tronconique 5 et un goulot cylindrique 6 s'étendant vers l'extérieur du récipient 2, la grande section du col étant solidaire du récipient 2, et la petite section du col étant solidaire du goulot 6. Ce récipient 2 est rempli d'une quantité convenable du produit à distribuer, en prenant soin de laisser un volume d'air libre, ce volume correspondant au volume du col 5.As shown in this figure, a container 2 is used comprising a frustoconical neck 5 and a cylindrical neck 6 extending towards the outside of the container 2, the large section of the neck being integral with the container 2, and the small section of the neck being secured to the neck 6. This container 2 is filled with a quantity of the product to be distributed, taking care to leave a volume of free air, this volume corresponding to the volume of the neck 5.

Ensuite, on fixe la pompe 7 sur le goulot 6 du récipient à l'aide de la bague 8. On met alors en place les moyens d'actionnement 9, de façon à engager la tige 10 de la pompe 7 dans l'embout creux 95 de ceux-ci. Par la suite, on exerce une pression sur les moyens d'actionnement de façon à enfoncer le col tronconique 5 à l'intérieur du récipient 2. Lors de cette opération, le col 5 se retrousse, et la pompe 7 avec sa bague de fixation 8 se trouve à l'intérieur du col 5. On se trouve alors dans la configuration montrée sur la figure 1, et l'ensemble de distribution est prêt à l'emploi.Then, the pump 7 is fixed to the neck 6 of the container using the ring 8. The actuating means 9 are then put in place, so as to engage the rod 10 of the pump 7 in the hollow nozzle. 95 of these. Subsequently, pressure is exerted on the actuating means so as to push the frustoconical neck 5 inside the container 2. During this operation, the neck 5 is rolled up, and the pump 7 with its fixing ring 8 is located inside the neck 5. We are then in the configuration shown in Figure 1, and the dispensing assembly is ready for use.

Pour distribuer une dose de produit, l'utilisateur appuie axialement plusieurs fois sur la tête de distribution 9, afin d'amorcer la pompe, comme indiqué par la flèche F. Par ailleurs, l'amorçage de la pompe est facilité, du fait d'une surpression régnante à l'intérieur du récipient 2 à la suite de l'enfoncement du col 5, car cette opération diminue le volume effectif du récipient. Après l'amorçage de la pompe, chaque actionnement de la tête de distribution 9 provoque l'éjection d'une dose de produit.To dispense a dose of product, the user presses the dispensing head 9 several times axially, in order to prime the pump, as indicated by the arrow F. Furthermore, priming of the pump is facilitated, due to 'A prevailing overpressure inside the container 2 following the depression of the neck 5, because this operation reduces the effective volume of the container. After priming the pump, each actuation of the dispensing head 9 causes the ejection of a dose of product.

Il est possible de prévoir un moyen de verrouillage (non représenté) de la tête de distribution 9, pour immobiliser celle-ci, par exemple pendant le transport ou le stockage de l'ensemble.It is possible to provide a locking means (not shown) of the dispensing head 9, to immobilize the latter, for example during transport or storage of the assembly.
