Description

La présente invention concerne un flacon destiné à contenir un produit liquide ou pâteux et comprenant un tube plongeur, ainsi qu'un dispositif de conditionnement et de distribution d'un produit liquide ou pâteux comprenant d'une part un tel flacon et d'autre part un dispositif de pompage, dépourvu de tube plongeur, monté de façon amovible et avec étanchéité sur un tel flacon.The present invention relates to a bottle for containing a liquid or pasty product and comprising a dip tube, and a device for packaging and dispensing a liquid or pasty product comprising on the one hand such a bottle and on the other hand a pumping device, devoid of dip tube, removably mounted and sealed on such a bottle.

L'invention vise également un kit comprenant une pluralité de tels flacons et un unique dispositif de pompage dépourvu de tube plongeur.The invention also relates to a kit comprising a plurality of such bottles and a single pumping device without a dip tube.

On connaît déjà des dispositifs de conditionnement et de distribution de produits liquides ou pâteux, tels que des gels ou des crèmes, utilisés dans le domaine de l'hygiène, de la pharmacie ou de la cosmétique par exemple.Methods for packaging and dispensing liquid or pasty products, such as gels or creams, used in the field of hygiene, pharmaceuticals or cosmetics for example, are already known.

Ces dispositifs de conditionnement et de distribution comprennent typiquement un flacon, contenant le produit, et une pompe montée sur le flacon et permettant la distribution du produit. La pompe est munie d'un tube plongeur qui s'étend à l'intérieur du flacon, sensiblement jusqu'au fond de celui-ci.These packaging and dispensing devices typically comprise a bottle, containing the product, and a pump mounted on the bottle and allowing the dispensing of the product. The pump is provided with a dip tube which extends inside the bottle, substantially to the bottom of it.

Selon un premier mode de réalisation connu, la pompe est montée sur le flacon de façon inamovible. On a donc un dispositif à usage unique, qui présente l'inconvénient d'être coûteux et de générer une grande quantité de déchets.According to a first known embodiment, the pump is mounted on the bottle irremovably. So we have a disposable device, which has the disadvantage of being expensive and generate a large amount of waste.

Selon un deuxième mode de réalisation connu, la pompe est montée sur le flacon de façon amovible, typiquement par vissage sur le col du flacon. Il est donc possible, lorsque le flacon est vide, de dévisser la pompe et de la revisser sur un nouveau flacon, plein. De ce fait, la quantité de déchets est moindre, et le coût global pour l'utilisateur est réduit, car la pompe constitue l'organe le plus cher du dispositif de conditionnement et de distribution.According to a second known embodiment, the pump is mounted on the bottle removably, typically by screwing on the neck of the bottle. It is therefore possible, when the bottle is empty, to unscrew the pump and screw it on a new bottle, full. As a result, the quantity of waste is less, and the overall cost for the user is reduced because the pump is the most expensive member of the packaging and dispensing device.

Toutefois, ce deuxième mode de réalisation présente l'inconvénient suivant : lorsque la pompe est ôtée du flacon vide pour être placée sur le flacon plein, le tube plongeur se retrouve à l'air libre. Or, ce tube est couvert et au moins partiellement rempli de produit. Il s'ensuit que l'on ne peut garantir la parfaite asepsie de ce type de dispositifs de conditionnement et de distribution, ce qui peut être rédhibitoire dans certaines applications, en pharmacie par exemple. En effet, lorsque le tube sera plongé dans le nouveau flacon, le produit qui y est contenu pourra être contaminé. Par ailleurs, il est généralement désagréable pour l'utilisateur de manipuler le tube couvert de produit, d'autant plus si ce produit est pâteux, lors du transfert de la pompe d'un flacon vide à un flacon plein.However, this second embodiment has the following disadvantage: when the pump is removed from the empty bottle to be placed on the full bottle, the plunger tube is found in the open air. However, this tube is covered and at least partially filled with product. It follows that we can not guarantee the perfect asepsis of this type of packaging and dispensing devices, which can be unacceptable in some applications, pharmacy for example. Indeed, when the tube is immersed in the new bottle, the product contained therein may be contaminated. Moreover, it is generally unpleasant for the user to manipulate the covered tube of product, especially if this product is pasty, when transferring the pump from an empty bottle to a full bottle.

D'autres dispositifs de conditionnement et de distribution sont proposés par les documents EP 0 240 817 , FR 2 593 147 et LU 88 593 . Le document EP 0240 817 décrit un flacon selon le préambule de la revendication 1.Other packaging and distribution devices are proposed by the documents EP 0 240 817 , FR 2,593,147 and LU 88,593 . The document EP 0240817 describes a bottle according to the preamble of claim 1.

La présente invention vise à remédier aux inconvénients mentionnés ci-dessus.The present invention aims to overcome the disadvantages mentioned above.

A cet effet, et selon un premier aspect, l'invention concerne un flacon destiné à contenir un produit liquide ou pâteux, ledit flacon présentant un axe et comprenant :

  • un corps comportant un fond à son extrémité amont et une ouverture à son extrémité aval, et muni de moyens d'assemblage réversible d'un dispositif de pompage du produit ;
  • un élément de fermeture obturant l'ouverture aval du corps avant la première utilisation du flacon, et pouvant être séparé du corps ;
et, en outre, une pièce intermédiaire montée à l'intérieur du corps, comportant une ouverture aval reliée à un tube plongeur appartenant au flacon et s'étendant sensiblement axialement dans le corps vers l'amont sensiblement jusqu'au fond, ladite pièce intermédiaire étant pourvue de moyens de raccordement étanche destinés à coopérer avec le dispositif de pompage, de façon à permettre l'évacuation du produit contenu dans le flacon par le tube plongeur, par pompage, ladite pièce intermédiaire étant solidaire du corps du flacon et non extractible dudit corps et montée de façon étanche contre la face intérieure dudit corps.For this purpose, and according to a first aspect, the invention relates to a bottle intended to contain a liquid or pasty product, said bottle having an axis and comprising:
  • a body having a bottom at its upstream end and an opening at its downstream end, and provided with reversible assembly means of a device for pumping the product;
  • a closure member closing the downstream opening of the body prior to the first use of the vial, and being separable from the body;
and, in addition, an intermediate piece mounted inside the body, having a downstream opening connected to a dip tube belonging to the bottle and extending substantially axially in the body upstream substantially to the bottom, said intermediate piece being provided with sealing connection means intended to cooperate with the pumping device, so as to allow the evacuation of the product contained in the bottle by the dip tube, by pumping, said intermediate piece being integral with the body of the bottle and not extractable from said body and mounted sealingly against the inner face of said body.

Les termes « amont » et « aval » sont définis par rapport au sens d'écoulement du liquide vers l'extérieur du flacon. Par « étanche », on entend une étanchéité au liquide contenu dans le flacon.The terms "upstream" and "downstream" are defined with respect to the direction of flow of the liquid towards the outside of the vial. "Waterproof" means a seal to the liquid contained in the bottle.

Ainsi, l'invention propose un flacon comportant un tube plongeur intégré, qui peut être associé à un dispositif de pompage dépourvu de tube plongeur. Par « intégré », il faut comprendre que le tube plongeur appartient au flacon (et non au dispositif de pompage). Selon un premier mode de réalisation, le tube plongeur est réalisé d'une seule pièce avec la pièce intermédiaire ; selon un deuxième mode de réalisation, ce tube plongeur est rapporté sur la pièce intermédiaire.Thus, the invention proposes a bottle comprising an integrated dip tube, which can be associated with a pumping device without a dip tube. By "integrated", it should be understood that the dip tube belongs to the bottle (and not to the pumping device). According to a first embodiment, the dip tube is made in one piece with the intermediate piece; according to a second embodiment, this dip tube is attached to the intermediate piece.

En pratique, le flacon est initialement obturé (par l'élément de fermeture) et le produit ne peut donc ni s'en écouler ni être contaminé par un élément extérieur. Au moment de la première utilisation, l'utilisateur sépare l'élément de fermeture du flacon, libérant ainsi l'ouverture aval du corps, puis positionne le dispositif de pompage. Ce dispositif de pompage peut ne pas comporter de tube plongeur, puisque ce tube est déjà prévu dans le flacon et que des moyens de raccordement étanche entre le flacon et le dispositif de pompage sont prévus. De ce fait, lorsque le dispositif de pompage est retiré d'un flacon vide pour être placé sur un flacon plein, on n'a pas de long tube couvert de produit à déplacer d'un flacon à l'autre.In practice, the bottle is initially closed (by the closure element) and the product can therefore neither leak nor be contaminated by an external element. At the moment of the first use, the user separates the closure element from the bottle, thus releasing the downstream opening of the body, then position the pumping device. This pumping device may not include a dip tube, since this tube is already provided in the bottle and that means for sealing connection between the bottle and the pumping device are provided. Therefore, when the pumping device is removed from an empty bottle to be placed on a full bottle, there is no long tube covered with product to move from one vial to another.

De plus, grâce à l'invention, il est possible de commercialiser un kit comprenant un unique dispositif de pompage pour plusieurs flacons, et donc de diminuer le prix à payer pour un utilisateur, pour une même quantité de produit.In addition, thanks to the invention, it is possible to market a kit comprising a single pumping device for several bottles, and thus to reduce the price to pay for a user for the same amount of product.

Il est à noter que la pièce intermédiaire est fixe par rapport au corps, et donc qu'elle ne peut pas être extraite du corps. Ceci est avantageux car on peut ainsi garantir l'hygiène du produit et la sécurité de l'utilisateur.It should be noted that the intermediate piece is fixed relative to the body, and therefore it can not be extracted from the body. This is advantageous because it can thus ensure product hygiene and user safety.

On peut en outre prévoir que la pièce intermédiaire ne dépasse pas au-delà de l'extrémité aval du corps, ce qui fait qu'un utilisateur n'a aucun accès à cette pièce.It can further be provided that the intermediate piece does not protrude beyond the downstream end of the body, so that a user has no access to this room.

Par exemple, le corps comporte une portion sensiblement cylindrique et un goulot de moindre diamètre qui est relié à cette portion sensiblement cylindrique par une paroi globalement transversale formant un épaulement. La pièce intermédiaire peut alors être montée en butée contre cet épaulement, en amont de celui-ci.For example, the body comprises a substantially cylindrical portion and a neck of smaller diameter which is connected to this substantially cylindrical portion by a generally transverse wall forming a shoulder. The intermediate piece can then be mounted in abutment against this shoulder, upstream thereof.

Le corps est par exemple réalisé à partir de deux pièces distinctes, réalisées par moulage par injection et assemblées après le montage de la pièce intermédiaire dans l'une d'elles.The body is for example made from two separate parts, made by injection molding and assembled after mounting the intermediate piece in one of them.

Selon une réalisation possible, la pièce intermédiaire comprend un logement axial ouvert à ses deux extrémités et reliant l'ouverture aval de la pièce intermédiaire et le tube plongeur, ledit logement étant destiné à recevoir avec étanchéité une partie du dispositif de pompage.According to one possible embodiment, the intermediate piece comprises an axial housing open at its two ends and connecting the downstream opening of the intermediate piece and the dip tube, said housing being intended to receive with sealing part of the pumping device.

Par exemple, la pièce intermédiaire comprend une paroi transversale dans laquelle est ménagée l'ouverture aval, une jupe faisant saillie de la paroi transversale vers l'amont, une portion généralement tubulaire faisant saillie de la paroi transversale vers l'amont, autour de l'ouverture aval, et dont la zone intérieure forme le logement de réception d'une partie du dispositif de pompage, l'ouverture amont de ladite portion généralement tubulaire étant directement reliée à l'ouverture aval du tube plongeur.For example, the intermediate piece comprises a transverse wall in which is formed the downstream opening, a skirt projecting from the transverse wall upstream, a generally tubular portion projecting from the transverse wall upstream, around the downstream opening, and whose inner zone forms the receiving housing of a portion of the pumping device, the upstream opening of said generally tubular portion being directly connected to the downstream opening of the plunger tube.

La portion généralement tubulaire peut comprendre, de l'amont vers l'aval :

  • une première partie cylindrique et une deuxième partie cylindrique de plus grand diamètre, un épaulement étant ainsi défini entre lesdites deux parties et formant une surface d'étanchéité destinée à être en contact avec une surface correspondante du dispositif de pompage ;
  • une partie s'évasant vers l'amont, formant une zone d'introduction du dispositif de pompage dans le logement.
The generally tubular portion may comprise, from upstream to downstream:
  • a first cylindrical portion and a second cylindrical portion of larger diameter, a shoulder being thus defined between said two portions and forming a sealing surface to be in contact with a corresponding surface of the pumping device;
  • a part flaring upstream, forming an introduction zone of the pumping device in the housing.

Avantageusement, la pièce intermédiaire est encliquetée à l'intérieur du corps. De la sorte, on obtient une bonne tenue axiale dans les deux sens, et on évite, lors de la mise en place du dispositif de pompage, de désolidariser la pièce intermédiaire du corps et de la pousser vers le fond.Advantageously, the intermediate piece is snapped inside the body. In this way, a good axial resistance is obtained in both directions, and during the installation of the pumping device, it is not possible to separate the intermediate piece from the body and push it towards the bottom.

Le corps comprend par exemple une partie principale sensiblement cylindrique, ouverte à son extrémité aval, et une coiffe montée sur la partie principale du côté de l'ouverture, avec étanchéité, la coiffe étant ouverte à ses deux extrémités axiales et la pièce intermédiaire étant montée à l'intérieur de la coiffe.The body comprises for example a substantially cylindrical main part, open at its downstream end, and a cap mounted on the main part of the opening side, with sealing, the cap being open at its two axial ends and the intermediate piece being mounted inside the cap.

Selon un deuxième aspect, l'invention concerne un dispositif de conditionnement et de distribution d'un produit liquide ou pâteux comprenant un flacon tel que précédemment défini et un dispositif de pompage monté sur le flacon de façon amovible et avec étanchéité, le dispositif de pompage étant dépourvu de tube plongeur.According to a second aspect, the invention relates to a device for packaging and dispensing a liquid or pasty product comprising a bottle as defined above and a pumping device mounted on the bottle removably and with sealing, the pumping device. being devoid of dip tube.

Selon une réalisation possible, dans ce dispositif de conditionnement et de distribution, le dispositif de pompage présente un axe et comprend :

  • une base munie de moyens d'assemblage réversible sur le flacon ;
  • une tête comportant un conduit débouchant par une extrémité à l'extérieur de la tête, montée mobile en translation axiale par rapport à la base entre une position haute et une position enfoncée, sous l'action d'appui d'un utilisateur, pour délivrer par le conduit une dose de produit contenu dans le flacon ;
  • un embout fixé dans la base et faisant saillie de celle-ci vers l'amont, l'embout comportant un canal axial ouvert à ses deux extrémités et en communication, en aval, avec le conduit ménagé dans la tête ;
l'embout étant dépourvu de tube plongeur et comprenant des moyens de raccordement étanche avec le flacon, permettant, en position assemblée du dispositif de pompage et du flacon, une mise en communication entre le canal axial de l'embout et le tube plongeur intégré au flacon.According to one possible embodiment, in this packaging and dispensing device, the pumping device has an axis and comprises:
  • a base provided with reversible assembly means on the bottle;
  • a head comprising a duct opening at one end to the outside of the head, mounted movably in axial translation relative to the base between a high position and a depressed position, under the action of support of a user, to deliver by the conduit a dose of product contained in the bottle;
  • a nozzle fixed in the base and projecting from it upstream, the nozzle having an axial channel open at both ends and in communication, downstream, with the conduit formed in the head;
the nozzle being devoid of a dip tube and comprising means for sealing connection with the bottle, allowing, in position assembly of the pumping device and the bottle, placing in communication between the axial channel of the nozzle and the plunger integrated in the bottle.

Là encore, le terme « intégré » ne signifie pas que le tube plongeur est formé d'une seule pièce avec le flacon. En effet, on peut prévoir, en variante, que ce tube plongeur soit une pièce séparée, rapportée sur le flacon. Le point essentiel est que ce tube plongeur appartient au flacon et non au dispositif de pompage.Again, the term "integrated" does not mean that the dip tube is formed in one piece with the bottle. Indeed, it can be provided, alternatively, that the dip tube is a separate piece, attached to the bottle. The essential point is that this dip tube belongs to the bottle and not to the pumping device.

L'embout peut comprendre, de l'amont vers l'aval :

  • une première partie sensiblement cylindrique et une deuxième partie cylindrique de plus grand diamètre, un épaulement étant ainsi défini entre lesdites deux parties et formant une surface d'étanchéité destinée à être en contact avec une surface correspondante du flacon ;
  • une partie s'évasant vers l'amont, destinée à être introduite dans un logement de forme complémentaire ménagé dans le flacon.
The tip may comprise, from upstream to downstream:
  • a first substantially cylindrical portion and a second cylindrical portion of larger diameter, a shoulder being thus defined between said two portions and forming a sealing surface for contact with a corresponding surface of the vial;
  • a part flaring upstream, intended to be introduced into a housing of complementary shape formed in the bottle.

Par exemple, la partie extrême de l'embout comporte une face extérieure convergeant vers l'amont, et présente une saillie radiale destinée à coopérer avec étanchéité avec une paroi du flacon. L'embout présente ainsi une partie extrême amont effilée qui facilite son introduction dans le flacon et permet d'obtenir une certaine souplesse. On obtient ainsi un effet ressort qui, en combinaison avec la présence de la saillie radiale, permet d'obtenir un très bon contact d'étanchéité avec le logement du flacon.For example, the end portion of the tip has an outer face converging upstream, and has a radial projection intended to cooperate sealingly with a wall of the bottle. The tip thus has a tapered upstream end portion that facilitates its introduction into the bottle and provides a certain flexibility. This gives a spring effect which, in combination with the presence of the radial projection, provides a very good sealing contact with the housing of the bottle.

Enfin, selon un troisième aspect, l'invention vise un kit comprenant une pluralité de flacons tels que précédemment décrits, chaque flacon étant rempli d'un produit liquide ou pâteux et obturé par un élément de fermeture, et un unique dispositif de pompage, disjoint des flacons (c'est-à-dire assemblé à aucun des flacons), le dispositif de pompage étant dépourvu de tube plongeur et comportant des moyens de raccordement étanche avec les flacons.Finally, according to a third aspect, the invention provides a kit comprising a plurality of bottles as previously described, each bottle being filled with a liquid or pasty product and closed by a closure element, and a single pumping device, disjointed vials (that is to say, assembled to any of the bottles), the pumping device being devoid of dip tube and having means for sealing connection with the bottles.

Le dispositif de pompage en question peut présenter les caractéristiques précitées.The pumping device in question may have the aforementioned characteristics.

Un tel kit peut être commercialisé à un prix très intéressant pour l'utilisateur, puisqu'il ne comprend qu'un seul dispositif de pompage pour plusieurs flacons, qui constituent des recharges.Such a kit can be marketed at a very attractive price for the user, since it comprises only one pumping device for several bottles, which constitute refills.

On décrit à présent, à titre d'exemple non limitatif, un mode de réalisation possible de l'invention, en référence aux figures annexées :

  • La figure 1 est une vue en coupe longitudinale, en position non entièrement montée, du flacon selon l'invention, avant la première utilisation ;

  • La figure 3 est une vue en coupe longitudinale du flacon ouvert, montrant la mise en place du dispositif de pompage ; et
  • La figure 4 est une vue en coupe longitudinale du dispositif de conditionnement et de distribution prêt à l'emploi.
We will now describe, by way of nonlimiting example, a possible embodiment of the invention, with reference to the appended figures:
  • The figure 1 is a longitudinal sectional view, in the fully assembled position, of the bottle according to the invention, before the first use;
  • The figure 2 is a longitudinal sectional view of the mounted bottle, showing the separation of the closure element;
  • The figure 3 is a longitudinal sectional view of the open bottle, showing the establishment of the pumping device; and
  • The figure 4 is a longitudinal sectional view of the packaging device and distribution ready for use.

Le dispositif de conditionnement et de distribution 1 selon l'invention présente un axe 2 et comprend un flacon 3 et un dispositif de pompage 4.The packaging and dispensing device 1 according to the invention has an axis 2 and comprises a bottle 3 and a pumping device 4.

On décrit tout d'abord le flacon 3 en référence aux figures 1 et 2.Firstly, bottle 3 is described with reference to figures 1 and 2 .

Le flacon 3 comprend une partie principale 5 sensiblement cylindrique pourvue d'un fond 6 à son extrémité amont, et d'une ouverture 7 à son extrémité aval. La face intérieure 8 de la partie principale 5 est cylindrique sur toute la hauteur, tandis que la face extérieure 9 présente une partie extrême aval également cylindrique mais de plus faible diamètre. La partie principale 5 comprend ainsi un bord aval 10 aminci définissant un épaulement en couronne 11 orthogonal à l'axe 2. Le bord aval 10 comporte un bourrelet 12 annulaire faisant saillie radialement de la face extérieure 9.The bottle 3 comprises a substantially cylindrical main part 5 provided with a bottom 6 at its upstream end, and an opening 7 at its downstream end. The inner face 8 of the main part 5 is cylindrical over the entire height, while the outer face 9 has a downstream end part also cylindrical but smaller diameter. The main part 5 thus comprises a thinned downstream edge 10 defining a crown shoulder 11 orthogonal to the axis 2. The downstream edge 10 comprises an annular bead 12 projecting radially from the outer face 9.

Le flacon 3 comprend également une coiffe 13 comportant une paroi transversale 14 pourvue d'un orifice central 15. De la paroi transversale 14 font saillie :

  • vers l'aval, un col 16 entourant l'orifice central 15, le col 16 étant pourvu d'un filetage extérieur 17 et d'un retour 18 annulaire intérieur définissant une ouverture aval 19 ;
  • vers l'amont, une jupe extérieure 20 périphérique pourvue d'une gorge intérieure 21 et une jupe intérieure 22, de plus grande longueur axiale que la jupe extérieure 20.
The bottle 3 also comprises a cap 13 comprising a transverse wall 14 provided with a central orifice 15. From the transverse wall 14 protrude:
  • downstream, a neck 16 surrounding the central orifice 15, the neck 16 being provided with an external thread 17 and an inner annular return 18 defining a downstream opening 19;
  • upstream, a peripheral outer skirt 20 provided with an inner groove 21 and an inner skirt 22, of greater axial length than the outer skirt 20.

La coiffe 13 est destinée à être encliquetée, de préférence de façon inamovible, sur la partie principale 5, formant ainsi le corps du flacon 3. En position montée (figure 2), le bord aval 10 de la partie principale 5 est enserré entre la jupe extérieure 20 et la jupe intérieure 22, le bourrelet 12 étant logé dans la gorge 21 et l'extrémité amont de la jupe extérieure 20 étant en butée contre l'épaulement en couronne 11. La face extérieure de la jupe intérieure 22 est en contact étanche avec la face intérieure 8 de la partie principale 5, et la face extérieure de la jupe extérieure 20 est située dans le prolongement de la face extérieure 9 de la partie principale 5 (dans sa partie de plus grande épaisseur), si bien que le corps du flacon 3 possède une face extérieure continue, sans décrochement.The cap 13 is intended to be snapped, preferably irremovably, on the main part 5, thus forming the body of the bottle 3. In mounted position ( figure 2 ), the downstream edge 10 of the main part 5 is sandwiched between the outer skirt 20 and the inner skirt 22, the bead 12 being housed in the groove 21 and the upstream end of the outer skirt 20 abuts against the shoulder in crown 11. The outer face of the inner skirt 22 is in sealing contact with the inner face 8 of the main part 5, and the outer face of the outer skirt 20 is located in the extension of the outer face 9 of the main part. 5 (in his part of greater thickness), so that the body of the bottle 3 has a continuous outer face, without recess.

L'ouverture aval du corps est obturée, avant la première utilisation, par un élément de fermeture. Cet élément de fermeture peut être un bouchon vissable (éventuellement muni d'un témoin d'inviolabilité tel qu'une bague) ou un opercule pelable ou un appendice sécable. Dans la réalisation représentée, on a un appendice sécable 23 réalisé d'une seule pièce avec la coiffe 13 et reliée à celle-ci, au niveau de l'ouverture aval 19, par une zone de jonction 24 de plus faible résistance.The downstream opening of the body is closed, before the first use, by a closure element. This closure element may be a screw cap (optionally provided with a tamper evidence such as a ring) or a peelable seal or a breakable appendage. In the embodiment shown, there is a breakable appendage 23 made in one piece with the cap 13 and connected thereto, at the downstream opening 19, by a junction zone 24 of lower resistance.

Enfin, le flacon 3 comprend une pièce intermédiaire 25. Cette pièce intermédiaire 25 comporte une paroi transversale 26 pourvue d'une ouverture centrale 27 et de laquelle font saillie, vers l'amont, d'une part, à sa périphérie, une jupe 28 et d'autre part, autour de l'ouverture centrale 27, une portion généralement tubulaire 29 dont la zone intérieure forme un logement 30 ouvert à ses deux extrémités axiales.Finally, the bottle 3 comprises an intermediate piece 25. This intermediate piece 25 has a transverse wall 26 provided with a central opening 27 and which project, upstream, on the one hand, at its periphery, a skirt 28 and secondly, around the central opening 27, a generally tubular portion 29 whose inner region forms a housing 30 open at its two axial ends.

La portion généralement tubulaire 29 comprend, de l'amont vers l'aval :

  • une tige creuse 31 de petit diamètre, et sur laquelle est emmanché un tube plongeur 32 s'étendant sensiblement axialement dans le corps, vers l'amont, sensiblement jusqu'au fond 6. En variante, le tube plongeur 32 et la pièce intermédiaire 25 pourraient constituer une seule pièce monobloc ;
  • une première partie cylindrique 33 de plus grand diamètre que la tige creuse 31, définissant une paroi radiale 34 contre laquelle le tube plongeur 32 vient en butée ;
  • une deuxième partie cylindrique 35 de plus grand diamètre que la première partie cylindrique 33, un épaulement 36 étant ainsi défini entre lesdites deux parties cylindriques 33, 35 ;
  • et une partie globalement tronconique 37 s'évasant vers l'aval.
The generally tubular portion 29 comprises, from upstream to downstream:
  • a hollow rod 31 of small diameter, and on which is fitted a dip tube 32 extending substantially axially in the body, upstream, substantially to the bottom 6. Alternatively, the dip tube 32 and the intermediate piece 25 could be a single piece;
  • a first cylindrical portion 33 of larger diameter than the hollow rod 31, defining a radial wall 34 against which the plunger tube 32 abuts;
  • a second cylindrical portion 35 of larger diameter than the first cylindrical portion 33, a shoulder 36 being thus defined between said two cylindrical portions 33, 35;
  • and a generally frustoconical portion 37 flaring downstream.

La pièce intermédiaire 25 est encliquetée dans la coiffe 13, des moyens d'encliquetage réciproques (non représentés) étant prévus à cet effet. En position montée de la pièce intermédiaire 25 dans la coiffe 13, la paroi transversale 26 est en butée contre la paroi transversale 14 de la coiffe 13, et la jupe 28 est en contact étanche avec la jupe intérieure 22 de la coiffe 13.The intermediate piece 25 is snapped into the cap 13, reciprocal latching means (not shown) being provided for this purpose. In the mounted position of the intermediate piece 25 in the cap 13, the transverse wall 26 abuts against the transverse wall 14 of the cap 13, and the skirt 28 is in sealed contact with the inner skirt 22 of the cap 13.

La partie principale 5, la coiffe 13 et la pièce intermédiaire 25 sont par exemple réalisées par moulage d'une matière plastique telle que le polypropylène.The main part 5, the cap 13 and the intermediate part 25 are for example made by molding a plastic material such as polypropylene.

On décrit à présent le dispositif de pompage 4, en référence à la figure 3.The pumping device 4 is now described with reference to FIG. figure 3 .

Le dispositif de pompage 4 comprend tout d'abord une base 38 comportant un filetage intérieur 39 destiné à coopérer avec le filetage extérieur 17 du col 16 de la coiffe 13.The pumping device 4 comprises first of all a base 38 having an internal thread 39 intended to cooperate with the external thread 17 of the neck 16 of the cap 13.

Le dispositif de pompage 4 comprend également une tête 40 comportant un premier conduit 41, oblique, débouchant par une extrémité à l'extérieur de la tête 40 et par une autre extrémité dans un second conduit 42, axial, muni d'orifices radiaux 43. La tête 40 est montée mobile en translation axiale par rapport à la base 38 entre une position haute et une position enfoncée, sous l'action d'appui d'un utilisateur, pour délivrer par les orifices 43 et les conduits 42, 41 une dose de produit contenu dans le flacon 3. La tête 40 est en outre sollicitée vers sa position haute par un ressort 44.The pumping device 4 also comprises a head 40 comprising a first duct 41, oblique, opening at one end outside the head 40 and at another end in a second duct 42, axial, provided with radial orifices 43. The head 40 is movably mounted in axial translation relative to the base 38 between a high position and a depressed position, under the action of a user, to deliver through the orifices 43 and the conduits 42, 41 a dose of product contained in the bottle 3. The head 40 is further biased towards its upper position by a spring 44.

Enfin, le dispositif de pompage 4 comprend un embout 45 fixé dans la base 38 et faisant saillie de celle-ci vers l'amont, au-delà de la base 38. L'embout 45 comporte un canal 46 axial ouvert à ses deux extrémités, pouvant communiquer avec le second conduit 42, via les orifices radiaux 43, lorsque la tête est en position enfoncée.Finally, the pumping device 4 comprises a tip 45 fixed in the base 38 and projecting from it upstream, beyond the base 38. The tip 45 comprises an axial channel 46 open at both ends , able to communicate with the second duct 42, via the radial orifices 43, when the head is in the depressed position.

L'embout 45 est destiné à être placé dans le logement 30 ménagé dans la pièce intermédiaire 25, et possède donc une forme extérieure correspondant à la forme intérieure de ce logement 30. Ainsi, l'embout 45 comprend, de l'amont vers l'aval :

  • une première partie sensiblement cylindrique 47 et une deuxième partie cylindrique 48 de plus grand diamètre, un épaulement 49 étant ainsi défini entre lesdites deux parties cylindriques 47, 48 ;
  • une partie globalement tronconique 50, s'évasant vers l'amont.
The end piece 45 is intended to be placed in the housing 30 formed in the intermediate part 25, and therefore has an outer shape corresponding to the inner shape of this housing 30. Thus, the endpiece 45 comprises, from upstream to 'downstream :
  • a first substantially cylindrical portion 47 and a second cylindrical portion 48 of larger diameter, a shoulder 49 being thus defined between said two cylindrical portions 47, 48;
  • a generally frustoconical part 50, flaring upstream.

La partie extrême de l'embout 45, au niveau de la première partie sensiblement cylindrique 47, comporte une face extérieure convergeant vers l'amont formant une rampe 51, et présente une saillie radiale 52.The end portion of the tip 45, at the first substantially cylindrical portion 47, has an outwardly converging outer face forming a ramp 51, and has a radial projection 52.

Il est à noter que, de façon essentielle à l'invention, le dispositif de pompage 4 ne comporte pas de tube plongeur, puisqu'il est destiné à être assemblé, de façon amovible et avec étanchéité, au flacon 3 qui comporte déjà un tube plongeur 32.It should be noted that, in an essential manner to the invention, the pumping device 4 does not include a dip tube, since it is intended to be assembled, removably and with sealing, to the bottle 3 which already comprises a tube diver 32.

On décrit à présent le mode d'assemblage des différentes parties constitutives du dispositif de conditionnement et de distribution 1 selon l'invention.The method of assembly of the various constituent parts of the packaging and dispensing device 1 according to the invention is now described.

Le flacon 3 est obtenu comme suit. Dans un premier temps, on assemble la pièce intermédiaire 25 (pourvue du tube plongeur 32 monobloc ou rapporté) et la coiffe 13 (pourvue de son élément de fermeture). Puis on vient encliqueter cet ensemble sur la partie principale 5 préalablement remplie du produit souhaité. C'est sous cette forme que le flacon 3 est commercialisé. Il est parfaitement étanche et constitue une recharge (atmosphérique).Vial 3 is obtained as follows. In a first step, the intermediate piece 25 (provided with the single-piece or insert plunger tube 32) and the cap 13 (provided with its closure member) are assembled. Then we just snap this set on the main part 5 previously filled with the desired product. It is in this form that the bottle 3 is marketed. It is perfectly waterproof and is a refill (atmospheric).

Lorsqu'un utilisateur souhaite obtenir une certaine quantité du produit contenu dans le flacon 3, il doit tout d'abord mettre en place le dispositif de pompage 4 sur le flacon 3.When a user wishes to obtain a certain quantity of the product contained in the bottle 3, he must first set up the pumping device 4 on the bottle 3.

Dans un premier temps, l'utilisateur libère l'ouverture aval 19 du flacon 3 en ôtant l'élément de fermeture (ici en détachant l'appendice 23, selon la zone de moindre résistance 24). Puis, il peut visser le dispositif de pompage 4 sur le flacon 3 (figure 3).At first, the user releases the downstream opening 19 of the bottle 3 by removing the closure element (here by detaching the appendage 23, according to the zone of least resistance 24). Then, it can screw the pumping device 4 onto the bottle 3 ( figure 3 ).

Lors de la mise en place du dispositif de pompage 4, l'embout 45 passe par l'ouverture 19 puis vient se positionner dans le logement 30. La partie globalement tronconique 37 de la pièce intermédiaire 25 forme une zone facilitant et guidant l'introduction du dispositif de pompage 4, de même que les rampes 51. Comme indiqué précédemment, les moyens d'encliquetage entre la partie intermédiaire 25 et la coiffe 13 sont agencés pour empêcher que le vissage du dispositif de pompage 4 ne provoque par poussée la séparation de la pièce intermédiaire 25 et de la coiffe 13.During the introduction of the pumping device 4, the tip 45 passes through the opening 19 and then is positioned in the housing 30. The generally frustoconical portion 37 of the intermediate piece 25 forms a facilitating and guiding the introduction area of the pumping device 4, as well as the ramps 51. As indicated above, the latching means between the intermediate part 25 and the cap 13 are arranged to prevent the screwing of the pumping device 4 from pushing the separation of the intermediate part 25 and the cap 13.

La figure 4 montre le dispositif de conditionnement et de distribution 1 prêt à l'emploi, le dispositif de pompage 4 étant vissé sur le flacon 3. Dans cette position, l'embout 45 épouse la forme du logement 30, l'extrémité de l'embout 45 étant en butée au fond de la pièce intermédiaire 25, juste en aval de la tige creuse 31, la saillie radiale 52 étant en contact avec la face intérieure de la première partie cylindrique 33 de la pièce intermédiaire 25. De plus, l'épaulement 49 de l'embout 45 est en contact avec l'épaulement 36 de la pièce intermédiaire, de façon étanche.The figure 4 shows the packaging and distribution device 1 ready to use, the pumping device 4 being screwed onto the bottle 3. In this position, the tip 45 matches the shape of the housing 30, the end of the tip 45 being in abutment with the bottom of the intermediate piece 25, just downstream of the hollow rod 31, the radial projection 52 being in contact with the inner face of the first cylindrical portion 33 of the intermediate piece 25. In addition, the shoulder 49 of the nozzle 45 is in contact with the shoulder 36 of the intermediate piece, sealingly.

Grâce à l'invention, on a des moyens de raccordement étanche entre le dispositif de pompage 4 et le flacon 3, c'est-à-dire avec le tube plongeur 32, qui permettent d'amorcer l'aspiration du produit par appui sur la tête 40. Il est à noter que le dispositif de conditionnement et de distribution 1 selon l'invention ne nécessite pas de joint d'étanchéité à cet effet.Thanks to the invention, there are means for sealing connection between the pumping device 4 and the bottle 3, that is to say with the dip tube 32, which make it possible to initiate the suction of the product by pressing on the head 40. It should be noted that the packaging and dispensing device 1 according to the invention does not require a seal for this purpose.

Ainsi, l'invention apporte une amélioration déterminante à la technique antérieure, en fournissant un dispositif de conditionnement et de distribution d'un produit qui, avec une structure simple, permet de réduire considérablement les coûts pour l'utilisateur. En effet, il est possible de commercialiser un kit comprenant plusieurs flacons recharge à tube plongeur intégré (par exemple 10) pour un unique dispositif de pompage. De plus, cette réduction des coûts s'accompagne d'une amélioration importante en termes d'asepsie et d'ergonomie pour l'utilisateur, qui ne risque plus de déposer du produit en divers endroits, et de façon non intentionnelle, lors du dévissage et du revissage du dispositif de pompage sur un flacon plein.Thus, the invention provides a decisive improvement to the prior art, providing a device for packaging and dispensing a product which, with a simple structure, can significantly reduce the costs for the user. Indeed, it is possible to market a kit comprising several refill bottles with integrated dip tube (for example 10) for a single pumping device. In addition, this cost reduction is accompanied by a significant improvement in terms of asepsis and ergonomics for the user, who is no longer at risk of depositing the product in various locations, and unintentionally, during unscrewing. and screwing the pumping device back onto a full flask.

Il va de soi que l'invention n'est pas limitée au mode de réalisation décrit ci-dessus à titre d'exemple mais qu'elle en embrasse au contraire toutes les variantes de réalisation telles que revendiquées.It goes without saying that the invention is not limited to the embodiment described above by way of example but that it encompasses all the variants as claimed.
