  • the bottle 1 has a conventional appearance, and comprises a reservoir 2 which provides an interior volume for containing a liquid or viscous product.
  • the product may have a dynamic viscosity of between 0.8 m mPa.s and 1000 mPa.s. With such a viscosity, the product can be dispensed without it being necessary to exert pressure on the reservoir.
  • the reservoir 2 can thus be rigid.
  • a deformable reservoir can be used for dispensing a product having a greater viscosity.
  • deformable reservoir we mean a reservoir that a user can deform by hand, with reasonable effort.
  • the reservoir 2 has a bottom 3 and a neck 4 (not visible in Figure 1, but visible for example in the sectional view of Figure 4).
  • the bottom 3 and the neck 4 are opposite in a so-called longitudinal direction L.
  • the bottle 1 extends in the example shown along a main axis parallel to the longitudinal direction L.
  • a cap 5 is fixed on the neck 4.
  • the cap 5 has, in the example shown here, the appearance of a conventional screw cap.
  • the cap 5 comprises a body 6 which forms its outer side wall.
  • the dispensing tip 7 comprises a dispensing orifice 8.
  • the dispensing orifice is oriented transversely, i.e. perpendicular to the longitudinal direction L.
  • a rotation of the body 6 causes a longitudinal translation of the dispensing tip 7.
  • This rotation makes it possible to move the dispensing tip 7 from the lowered position shown in Figure 1 to the raised position shown in Figure 2.
  • the dispensing orifice 8 is closed, in this case by the body 6.
  • the dispensing tip 7 then forms the upper surface of the cap 5.
  • the dispensing orifice is free, so that dispensing of the product contained in the reservoir is possible.
  • the cap 5 includes a mechanism making it possible to transform the rotation of the body 6 into a translation (preferably a simple translation, or possibly a translation combined with a rotation) of the dispensing tip.
  • Figure 3 and Figure 4 represent a first example of a mechanism allowing this.
  • the body 6 is shown in transparency in Figure 3.
  • Figure 4 is a sectional view, along a plane AA shown in Figure 1.
  • the cap 5 comprises a sleeve 9 which is fixed on the neck 4.
  • the sleeve 9 is screwed onto a thread 10 of the neck 4.
  • the tightening of the sleeve 9 on the neck 4 ensures that it is locked in rotation, a relatively large force being necessary to cause it to loosen.
  • a snap-on or clip-on attachment may be used, with a means locking the sleeve from rotating relative to the neck.
  • the dispensing nozzle comprises at least one pin 11, which extends transversely.

  • the end portion 14 is better visible in Figure 6 which is described below.
  • This end portion 14 is optional and provides a certain stability to the raised and lowered positions of the dispensing nozzle. It prevents the dispensing nozzle from being able, for example, to be retracted into the body 6 by pressing on it longitudinally: when the pin 11 is in the end portion, a rotation of the body is necessary to engage the pin in the portion of the turn formed by the ramp 13.
  • the bottle can be closed by simply pressing on the dispensing nozzle, in the longitudinal direction.
  • the bottle can then be closed either conventionally by turning the body 6 of the cap, or using a very simple gesture by pressing on the dispensing tip which then causes the body 6 to rotate, which can be useful when the user has wet or slippery hands.

  • the protrusions (or the bead) could be formed on the inner surface of the body 6, while the corresponding groove 17 would be formed on the sleeve 9.
  • the cap is configured so that the torque required to cause the dispensing tip to move by turning the body 6 is less, and preferably much less, than the torque required to unscrew the cap from the neck. This prevents any involuntary unscrewing of the cap, but nevertheless allows the cap to be removed by continuing to unscrew it, with greater torque, once the dispensing tip has been brought into the raised position.
  • the dispensing nozzle forms a channel 15, which is free of any obstacle and which allows the product to pass from the reservoir 2 to the dispensing orifice 8.

For example, the outlet surface 22 of the valve is then in contact with the inner surface of the body 6, which prevents any product from escaping.
  • Figures 6 and 7 are essentially identical to that of Figures 1 to 5, except that this embodiment does not include a valve at the outlet of the dispensing nozzle. Therefore, the dispensing orifice can have a calibrated section, depending on the nature of the product contained in the bottle, to ensure dispensing with a flow rate that is neither too low nor too high. In the example presented, the section of the dispensing orifice is rectangular, so that this section can be relatively large despite a low lift of the dispensing nozzle. The unexpected exit of product is avoided by a good fit between the inner surface of the body 6 and the dispensing nozzle 7.
  • a flexible element for example made of elastomer, can be positioned on the inner face of the body 6 opposite the dispensing orifice when the dispensing nozzle is in the lowered position. This flexible element then makes it possible to perfect the seal at the dispensing orifice, when the bottle is closed.

Description

Flacon pour produit liquide ou visqueux Bottle for liquid or viscous product

DOMAINE TECHNIQUE DE L’INVENTION TECHNICAL FIELD OF THE INVENTION

[001] Le domaine de l’invention est celui du conditionnement et de la distribution des produits de consistance liquide ou visqueuse. La présente invention vise tout particulièrement la distribution de produits du domaine cosmétique, pharmaceutique ou alimentaire. Elle vise notamment la distribution de crèmes, laits, liquides ou gels (par exemple de gels lavants) destinés à être appliqués sur le corps d’un utilisateur. Ces produits sont typiquement contenus dans des flacons dotés de capuchons qui ont une dimension transversale d’au plus quelques centimètres. [001] The field of the invention is that of the packaging and distribution of products of liquid or viscous consistency. The present invention particularly relates to the distribution of products in the cosmetic, pharmaceutical or food fields. It particularly relates to the distribution of creams, milks, liquids or gels (for example washing gels) intended to be applied to the body of a user. These products are typically contained in bottles provided with caps which have a transverse dimension of at most a few centimeters.

[002] La présente invention vise ainsi un capuchon, et un flacon comportant un tel capuchon, pour la distribution d’un produit liquide ou visqueux, en particulier un produit destiné à une application corporelle. [002] The present invention thus relates to a cap, and a bottle comprising such a cap, for dispensing a liquid or viscous product, in particular a product intended for bodily application.

ÉTAT DE LA TECHNIQUE STATE OF THE ART

[003] On connaît déjà diverses structures de capuchons (également appelés capsules) permettant la distribution de produits contenus dans des flacons sur le col desquels de tels capuchons sont montés (en pratique par vissage ou clipsage). [003] Various cap structures (also called capsules) are already known for dispensing products contained in bottles on the neck of which such caps are mounted (in practice by screwing or clipping).

[004] On connaît notamment des capuchons qui en configuration de fermeture ont l'apparence de simples bouchons à vis, tandis qu’en configuration ouverte (de distribution), une partie supérieure de la capsule est déplacée en sorte de permettre une sortie de produit par un orifice de sortie. [004] Caps are known in particular which, in the closed configuration, have the appearance of simple screw caps, while in the open (dispensing) configuration, an upper part of the capsule is moved so as to allow product to exit through an outlet orifice.

[005] Par exemple le document FR2954754 présente un tel capuchon. Ainsi, ce document présente une capsule distributrice pour flacon de produit de consistance liquide ou visqueuse qui comporte un corps de capsule et une pièce de dessus adaptée à être déplacée par rapport à ce corps entre une configuration fermée et une configuration de distribution. La capsule, et notamment sa pièce de dessus, est configurée de sorte que la paroi supérieure de la capsule est constituée en totalité par la paroi supérieure de la pièce de dessus, et la capsule et la pièce de dessus comportent des surfaces complémentaires en portion de sphère adaptées à glisser l'une le long de l'autre de la configuration fermée à la configuration de distribution et inversement. Bien que cette capsule soit particulièrement pratique et esthétique, il est souhaitable de développer d’autres capuchons offrant une cinématique alternative, notamment dans laquelle toute partie mobile du capuchon ne dépasse par transversalement du reste du capuchon. En outre, il est intéressant de prévoir un capuchon pouvant être détaché du reste du flacon pour permettre de remplir de nouveau le réservoir lorsque tout le produit qu’il contenait a été utilisé. [006] On connaît par ailleurs des flacons de produit liquide qui comportent un embout formant capuchon monté sur leur col et dont la rotation permet l’activation ou la désactivation d’une pompe. [005] For example, document FR2954754 presents such a cap. Thus, this document presents a dispensing capsule for a bottle of product of liquid or viscous consistency which comprises a capsule body and a top piece adapted to be moved relative to this body between a closed configuration and a dispensing configuration. The capsule, and in particular its top piece, is configured so that the upper wall of the capsule is entirely constituted by the upper wall of the top piece, and the capsule and the top piece comprise complementary surfaces in the form of a portion of a sphere adapted to slide along one another from the closed configuration to the dispensing configuration and vice versa. Although this capsule is particularly practical and aesthetic, it is desirable to develop other caps offering alternative kinematics, in particular in which any movable part of the cap does not protrude transversely from the rest of the cap. In addition, it is advantageous to provide a cap which can be detached from the rest of the bottle to allow the reservoir to be refilled when all the product it contained has been used. [006] Furthermore, bottles of liquid product are known which have a tip forming a cap mounted on their neck and the rotation of which allows the activation or deactivation of a pump.

[007] Par exemple, le document EP1954596 divulgue un flacon à pompe qui comporte un embout monté sur un étui, dont la rotation permet de lever ou de baisser un bouton d’activation de la pompe. Plus précisément, une pompe est solidaire d’une cartouche comportant le produit à distribuer. Cet ensemble comporte au moins une protrusion qui est placée dans un ensemble de guides sous forme de rampes que comporte l’étui. La rotation de l’embout entraine un soulèvement de la cartouche et de la pompe, ce qui libère pour l’utilisateur le bouton d’actionnement de la pompe, pour délivrer le produit en actionnant la pompe par pression sur ce bouton. [007] For example, document EP1954596 discloses a pump bottle which comprises a tip mounted on a case, the rotation of which makes it possible to raise or lower a pump activation button. More precisely, a pump is secured to a cartridge containing the product to be dispensed. This assembly comprises at least one protrusion which is placed in a set of guides in the form of ramps which the case comprises. The rotation of the tip causes the cartridge and the pump to be lifted, which frees the pump activation button for the user, to deliver the product by activating the pump by pressing this button.

[008] De manière assez similaire, le document WO2013178927 présente un flacon pour la délivrance d’un produit liquide à l’aide d’une pipette. Grâce à un mécanisme analogue, la rotation d’un capuchon permet dans un premier temps de soulever un bouton d’actionnement de la pipette puis de dévisser le capuchon. Ainsi, le bouton d’actionnement étant libéré, l’utilisateur peut le presser une première fois pour aspirer du produit dans la pipette, puis une nouvelle fois pour distribuer le produit. [008] In a fairly similar manner, document WO2013178927 presents a bottle for dispensing a liquid product using a pipette. Thanks to a similar mechanism, the rotation of a cap initially allows an actuation button of the pipette to be lifted and then the cap to be unscrewed. Thus, with the actuation button released, the user can press it once to draw product into the pipette, then again to dispense the product.

[009] Ce type de cinématique, dans laquelle la rotation d’un embout ou capuchon provoque une translation d’un élément de distribution d’un flacon, est apprécié. Néanmoins, les dispositifs connus permettent d’autoriser ou d’empêcher l’actionnement d’un mécanisme de pompage, mais ils ne sont pas adaptés à la distribution d’un produit en l’absence d’un tel mécanisme de pompage. [009] This type of kinematics, in which the rotation of a tip or cap causes a translation of a dispensing element of a bottle, is appreciated. Nevertheless, the known devices make it possible to authorize or prevent the actuation of a pumping mechanism, but they are not suitable for the dispensing of a product in the absence of such a pumping mechanism.

EXPOSÉ DE L’INVENTION STATEMENT OF THE INVENTION

[010] La présente invention vise à remédier à tout ou partie des inconvénients de l’état de la technique cités ci-dessus. [010] The present invention aims to remedy all or part of the drawbacks of the state of the art cited above.

[011] À cet effet, l’invention vise un flacon pour produit liquide ou visqueux, dans lequel le flacon comporte un réservoir ayant un volume intérieur adapté à contenir le produit, le réservoir comportant un fond et un col qui sont opposés selon une direction dite longitudinale, le flacon comportant en outre un capuchon fixé sur le col du réservoir. [011] To this end, the invention relates to a bottle for a liquid or viscous product, in which the bottle comprises a reservoir having an interior volume adapted to contain the product, the reservoir comprising a bottom and a neck which are opposite in a so-called longitudinal direction, the bottle further comprising a cap fixed on the neck of the reservoir.

[012] Le capuchon comporte un corps rotatif vis-à-vis du réservoir et un embout de distribution formant un canal entre le volume intérieur du réservoir et un orifice de distribution. Le capuchon comporte un mécanisme configuré pour transformer une rotation du corps en une translation longitudinale de l’embout de distribution, entre une position baissée dans laquelle un orifice de distribution est obturé, et une position levée dans laquelle l’orifice de distribution est libéré. [013] Le capuchon comporte un manchon fixe par rapport au réservoir, le manchon comportant une portion d’étanchéité qui s’étend longitudinalement au moins en partie à l’intérieur du col et qui comporte une surface intérieure, l’embout de distribution comportant une partie inférieure montée coulissante longitudinalement dans ladite portion d’étanchéité de sorte qu’une étanchéité est réalisée entre la surface intérieure de la portion d’étanchéité du manchon et une surface (par exemple une surface extérieure) de la partie inférieure de l’embout de distribution. [012] The cap comprises a body rotatable with respect to the reservoir and a dispensing nozzle forming a channel between the interior volume of the reservoir and a dispensing orifice. The cap comprises a mechanism configured to transform a rotation of the body into a longitudinal translation of the dispensing nozzle, between a lowered position in which a dispensing orifice is closed, and a raised position in which the dispensing orifice is released. [013] The cap comprises a sleeve fixed relative to the reservoir, the sleeve comprising a sealing portion which extends longitudinally at least partly inside the neck and which comprises an inner surface, the dispensing nozzle comprising a lower part mounted to slide longitudinally in said sealing portion so that a seal is produced between the inner surface of the sealing portion of the sleeve and a surface (for example an outer surface) of the lower part of the dispensing nozzle.

[014] Un tel flacon présente une cinématique d’ouverture appréciable, et ne présente aucun risque de perte d’un bouchon. En outre, la configuration de capuchon proposée, avec notamment un manchon qui se fixe sur le col du réservoir et qui forme une surface d’étanchéité à l’intérieur de ce col permet d’assurer une étanchéité au produit dans le mécanisme et plus généralement au niveau du capuchon. [014] Such a bottle has appreciable opening kinematics, and presents no risk of losing a cap. In addition, the proposed cap configuration, with in particular a sleeve which is fixed on the neck of the reservoir and which forms a sealing surface inside this neck, makes it possible to ensure a seal for the product in the mechanism and more generally at the level of the cap.

[015] Afin de former le mécanisme, le corps peut comporter une rampe décrivant une portion de spire et le manchon peut comporter un guide longitudinal, l’embout de distribution comportant au moins un pion, le pion s’étendant dans le guide longitudinal et étant engagé dans la rampe. [015] In order to form the mechanism, the body may comprise a ramp describing a portion of a turn and the sleeve may comprise a longitudinal guide, the distribution endpiece comprising at least one pin, the pin extending into the longitudinal guide and being engaged in the ramp.

[016] Alternativement, afin de former ledit mécanisme, le manchon peut comporter une rampe décrivant une portion de spire et le corps peut comporter un guide longitudinal, l’embout de distribution comportant au moins un pion, le pion s’étendant dans le guide longitudinal et étant engagé dans la rampe. [016] Alternatively, in order to form said mechanism, the sleeve may comprise a ramp describing a portion of a turn and the body may comprise a longitudinal guide, the dispensing end piece comprising at least one pin, the pin extending into the longitudinal guide and being engaged in the ramp.

[017] L’ embout de distribution peut comporter deux parties montées libres en rotation, à savoir la partie inférieure comportant la portion d’étanchéité et le pion, et une partie supérieure comportant l’orifice de distribution, la partie supérieure étant bloquée en rotation vis-à-vis du manchon. [017] The dispensing nozzle may comprise two parts mounted free to rotate, namely the lower part comprising the sealing portion and the pin, and an upper part comprising the dispensing orifice, the upper part being blocked in rotation with respect to the sleeve.

[018] La portion d’étanchéité peut être légèrement conique et peut comporter une partie extrémale amincie déformable qui est en contact avec la partie inférieure de l’embout de distribution. [018] The sealing portion may be slightly tapered and may include a deformable thinned end portion that contacts the lower portion of the dispensing tip.

[019] Un joint annulaire peut être interposé entre la portion d’étanchéité du manchon et la partie inférieure de l’embout de distribution. [019] An annular seal may be interposed between the sealing portion of the sleeve and the lower part of the dispensing nozzle.

[020] La portion d’étanchéité peut être cylindrique droite et la partie inférieure de l’embout de distribution peut avoir une section transversale correspondant, à un jeu fonctionnel près, à celle de la portion d’étanchéité. [020] The sealing portion may be straight cylindrical and the lower part of the dispensing nozzle may have a cross-section corresponding, within a functional clearance, to that of the sealing portion.

[021] La partie inférieure de l’embout de distribution peut être cylindrique, par exemple cylindrique de révolution. [021] The lower part of the dispensing nozzle may be cylindrical, for example cylindrical of revolution.

[022] La portion d’étanchéité du manchon et la partie inférieure de l’embout de distribution peuvent être dimensionnées de sorte que ladite partie inférieure de l’embout de distribution s’étend longitudinalement au-delà de la portion d’étanchéité, vers le réservoir du flacon, tant dans la position baissée que dans la position levée de l’embout de distribution. [022] The sealing portion of the sleeve and the lower portion of the dispensing nozzle may be sized such that said lower portion of the dispensing nozzle dispensing extends longitudinally beyond the sealing portion, towards the bottle reservoir, both in the lowered position and in the raised position of the dispensing tip.

[023] La longueur de la portion d’étanchéité est avantageusement supérieure ou égale à 2 mm, de préférence supérieure ou égale à 5 mm. [023] The length of the sealing portion is advantageously greater than or equal to 2 mm, preferably greater than or equal to 5 mm.

[024] Le flacon peut comporter une valve au niveau de l’orifice de distribution. [024] The bottle may have a valve at the dispensing orifice.

[025] Le capuchon peut être clipsé sur le col du flacon. [025] The cap can be clipped onto the neck of the bottle.

[026] Alternativement, le capuchon peut être vissé sur le col du flacon. [026] Alternatively, the cap may be screwed onto the neck of the bottle.

[027] Le flacon peut être configuré de sorte que, partant de la position baissée de l’embout de distribution, une rotation dans le sens antihoraire du corps avec un premier couple minimal, entraine le passage de l’embout de distribution dans la position levée puis, la rotation étant poursuivie avec un deuxième couple minimal, supérieur au premier couple minimal, la rotation entraine le dévissage du capuchon. [027] The bottle may be configured so that, starting from the lowered position of the dispensing tip, a counterclockwise rotation of the body with a first minimum torque causes the dispensing tip to move into the raised position and then, the rotation being continued with a second minimum torque, greater than the first minimum torque, the rotation causes the cap to unscrew.

[028] Le flacon peut contenir par exemple un sérum, une huile, un lait, un fond de teint liquide, un gel lavant, un shampoing, un crème de faible viscosité, une lotion, ou un démaquillant, [028] The bottle may contain, for example, a serum, an oil, a milk, a liquid foundation, a washing gel, a shampoo, a low-viscosity cream, a lotion, or a makeup remover,

[030] La présente description est donnée à titre d’exemple de réalisation non limitatif. [031] La figure 1 représente un flacon conforme à un mode de réalisation de l’invention. Le flacon 1 a une apparence classique, et comporte un réservoir 2 qui ménage un volume intérieur pour contenir un produit liquide ou visqueux. A simple titre d’exemple, le produit peut avoir une viscosité dynamique comprise entre 0,8m mPa.s et 1000 mPa.s. Avec une telle viscosité, le produit peut être distribué sans qu’il soit nécessaire d’exercer une pression sur le réservoir. Le réservoir 2 peut ainsi être rigide. Néanmoins, en alternative à un réservoir rigide, un réservoir déformable peut être utilisé pour la distribution d’un produit ayant une viscosité plus grande. Par réservoir déformable, il est entendu un réservoir qu’un utilisateur peut déformer à la main, avec un effort raisonnable. [030] The present description is given as a non-limiting example of an embodiment. [031] Figure 1 represents a bottle according to one embodiment of the invention. The bottle 1 has a conventional appearance, and comprises a reservoir 2 which provides an interior volume for containing a liquid or viscous product. As a simple example, the product may have a dynamic viscosity of between 0.8 m mPa.s and 1000 mPa.s. With such a viscosity, the product can be dispensed without it being necessary to exert pressure on the reservoir. The reservoir 2 can thus be rigid. However, as an alternative to a rigid reservoir, a deformable reservoir can be used for dispensing a product having a greater viscosity. By deformable reservoir, we mean a reservoir that a user can deform by hand, with reasonable effort.

[032] Le réservoir 2 comporte un fond 3 et un col 4 (non visible à la figure 1 , mais visible par exemple sur la vue en coupe de la figure 4). Le fond 3 et le col 4 sont opposés selon une direction dite longitudinale L. Le flacon 1 s’étend dans l’exemple représenté selon un axe principal parallèle à la direction longitudinale L. [032] The reservoir 2 has a bottom 3 and a neck 4 (not visible in Figure 1, but visible for example in the sectional view of Figure 4). The bottom 3 and the neck 4 are opposite in a so-called longitudinal direction L. The bottle 1 extends in the example shown along a main axis parallel to the longitudinal direction L.

[033] Un capuchon 5 est fixé sur le col 4. Le capuchon 5 a, dans l’exemple ici représenté, l’apparence d’un bouchon à vis classique. [033] A cap 5 is fixed on the neck 4. The cap 5 has, in the example shown here, the appearance of a conventional screw cap.

[034] Le capuchon 5 comporte un corps 6 qui forme sa paroi latérale extérieure. Une rotation du corps 6, de préférence dans le sens classique d’un dévissage, c’est-à-dire en sens antihoraire, entraine la sortie d’un embout de distribution 7 comme montré à la figure 2. L’embout de distribution 7 comporte un orifice de distribution 8. L’orifice de distribution est orienté transversalement, c’est-à-dire perpendiculairement à la direction longitudinale L. [034] The cap 5 comprises a body 6 which forms its outer side wall. A rotation of the body 6, preferably in the conventional direction of unscrewing, i.e. counterclockwise, causes a dispensing tip 7 to come out as shown in Figure 2. The dispensing tip 7 comprises a dispensing orifice 8. The dispensing orifice is oriented transversely, i.e. perpendicular to the longitudinal direction L.

[035] Ainsi, une rotation du corps 6 entraine une translation longitudinale de l’embout de distribution 7. Cette rotation permet de faire passer l’embout de distribution 7 de la position baissée représentée à la figure 1 , à la position levée représentée à la figure 2. Dans la position baissée, l’orifice de distribution 8 est obturé, en l’occurrence par le corps 6. L’embout de distribution 7 forme alors la surface supérieure du capuchon 5. Dans la position levée l’orifice de distribution est libéré, de sorte que la distribution du produit contenu dans le réservoir est possible. [035] Thus, a rotation of the body 6 causes a longitudinal translation of the dispensing tip 7. This rotation makes it possible to move the dispensing tip 7 from the lowered position shown in Figure 1 to the raised position shown in Figure 2. In the lowered position, the dispensing orifice 8 is closed, in this case by the body 6. The dispensing tip 7 then forms the upper surface of the cap 5. In the raised position, the dispensing orifice is free, so that dispensing of the product contained in the reservoir is possible.

[036] Pour ce faire, le capuchon 5 comporte un mécanisme permettant de transformer la rotation du corps 6 en une translation (de préférence une translation simple, ou éventuellement une translation combinée à une rotation) de l’embout de distribution. [036] To do this, the cap 5 includes a mechanism making it possible to transform the rotation of the body 6 into a translation (preferably a simple translation, or possibly a translation combined with a rotation) of the dispensing tip.

[037] La figure 3 et la figure 4 représentent un premier exemple de mécanisme permettant cela. Pour plus de compréhension, le corps 6 est représenté en transparence sur la figure 3. La figure 4 est une vue en coupe, selon un plan A-A représenté à la figure 1 . [038] Le capuchon 5 comporte un manchon 9 qui est fixé sur le col 4. Dans l’exemple ici représenté, le manchon 9 est vissé sur un filetage 10 du col 4. Le serrage du manchon 9 sur le col 4 assure son blocage en rotation, une force relativement importante étant nécessaire à provoquer son desserrage. [037] Figure 3 and Figure 4 represent a first example of a mechanism allowing this. For better understanding, the body 6 is shown in transparency in Figure 3. Figure 4 is a sectional view, along a plane AA shown in Figure 1. [038] The cap 5 comprises a sleeve 9 which is fixed on the neck 4. In the example shown here, the sleeve 9 is screwed onto a thread 10 of the neck 4. The tightening of the sleeve 9 on the neck 4 ensures that it is locked in rotation, a relatively large force being necessary to cause it to loosen.

[039] Alternativement, une fixation par emboîtement ou clipsage peut être utilisée, avec un moyen bloquant le manchon en rotation vis-à-vis du col. [039] Alternatively, a snap-on or clip-on attachment may be used, with a means locking the sleeve from rotating relative to the neck.

[040] L’ embout de distribution comporte au moins un pion 11 , qui s’étend transversalement. Dans l’exemple ici représenté, l’embout de distribution comporte deux pions 11 diamétralement opposés (le manchon étant ici globalement cylindrique de révolution). [040] The dispensing nozzle comprises at least one pin 11, which extends transversely. In the example shown here, the dispensing nozzle comprises two diametrically opposed pins 11 (the sleeve here being generally cylindrical in revolution).

[041] Le pion traverse un guide longitudinal 12, qui est une fente longitudinale formée dans le manchon 9. Le guide longitudinal 12 a une largeur I qui correspond à celle du pion 11 à un jeu fonctionnel près permettant au pion de se translater sans effort dans le guide longitudinal 12. [041] The pin passes through a longitudinal guide 12, which is a longitudinal slot formed in the sleeve 9. The longitudinal guide 12 has a width I which corresponds to that of the pin 11 with a functional clearance allowing the pin to translate effortlessly in the longitudinal guide 12.

[042] L’ extrémité du pion est en outre engagée dans une rampe 13. La rampe 13 est une rainure formée sur une surface interne du corps 6, dans l’épaisseur dudit corps 6. La rampe 13 a préférentiellement une largeur L qui correspond à celle du pion 11 à un jeu fonctionnel près permettant au pion de se translater sans effort dans la rampe 13. [042] The end of the pin is further engaged in a ramp 13. The ramp 13 is a groove formed on an internal surface of the body 6, in the thickness of said body 6. The ramp 13 preferably has a width L which corresponds to that of the pin 11 with a functional clearance allowing the pin to translate effortlessly in the ramp 13.

[043] La rampe 13 forme une portion de spire, par exemple sur environ un quart de tour. La rampe 13 comporte néanmoins deux portions extrémales 14 qui sont plates, c’est-à- dire qu’elles s’étendent dans un plan transversal (perpendiculaire à la direction longitudinale). La portion extrémale 14 est mieux visible à la figure 6 qui est décrite ci-après. Cette portion extrémale 14 est optionnelle et apporte une certaine stabilité aux positions relevée et baissée de l’embout de distribution. Elle permet d’éviter que l’embout de distribution puisse par exemple être rentré dans le corps 6 en appuyant dessus longitudinalement : lorsque le pion 11 est dans la portion extrémale, une rotation du corps est nécessaire pour engager le pion dans la portion de spire formée par la rampe 13. A contrario, en l’absence de portion extrémale 14 plate le flacon peut être refermé par simple pression sur l’embout de distribution, dans la direction longitudinale. Le flacon peut alors être fermé soit classiquement en tournant le corps 6 du capuchon, soit selon une gestuelle très simple par pression sur l’embout de distribution qui entraine alors la rotation du corps 6, ce qui peut être intéressant lorsque l’utilisateur a les mains mouillées ou glissantes. [043] The ramp 13 forms a portion of a turn, for example about a quarter of a turn. The ramp 13 nevertheless comprises two end portions 14 which are flat, that is to say they extend in a transverse plane (perpendicular to the longitudinal direction). The end portion 14 is better visible in Figure 6 which is described below. This end portion 14 is optional and provides a certain stability to the raised and lowered positions of the dispensing nozzle. It prevents the dispensing nozzle from being able, for example, to be retracted into the body 6 by pressing on it longitudinally: when the pin 11 is in the end portion, a rotation of the body is necessary to engage the pin in the portion of the turn formed by the ramp 13. Conversely, in the absence of a flat end portion 14 the bottle can be closed by simply pressing on the dispensing nozzle, in the longitudinal direction. The bottle can then be closed either conventionally by turning the body 6 of the cap, or using a very simple gesture by pressing on the dispensing tip which then causes the body 6 to rotate, which can be useful when the user has wet or slippery hands.

[044] Ainsi, la rotation du corps 6 provoque (ou suit) un mouvement relatif du pion 11 dans la rampe 13, tandis que le pion 11 (et donc l’embout de distribution) est maintenu fixe en rotation par le guide longitudinal 12. Il en résulte un mouvement longitudinal de l’embout de distribution 7. [044] Thus, the rotation of the body 6 causes (or follows) a relative movement of the pin 11 in the ramp 13, while the pin 11 (and therefore the distribution nozzle) is kept fixed in rotation by the longitudinal guide 12. This results in a longitudinal movement of the distribution nozzle 7.

[045] Afin de permettre la rotation du corps 6, ce dernier est monté rotatif sur le manchon 9. A cette fin, dans l’exemple représenté le manchon 9 est pourvu de protrusions radiales 16 et le corps est doté, sur la surface intérieure, d’une gorge annulaire 17 dans laquelle sont engagées les protrusions radiales 16. Bien évidemment, les protrusions 16 pourraient être remplacées par un bourrelet périphérique. En outre, les protrusions (ou le bourrelet) pourraient être formées sur la surface intérieure du corps 6, tandis que la gorge 17 correspondante serait formée sur le manchon 9. [045] In order to allow rotation of the body 6, the latter is rotatably mounted on the sleeve 9. To this end, in the example shown the sleeve 9 is provided with protrusions radials 16 and the body is provided, on the inner surface, with an annular groove 17 in which the radial protrusions 16 are engaged. Obviously, the protrusions 16 could be replaced by a peripheral bead. Furthermore, the protrusions (or the bead) could be formed on the inner surface of the body 6, while the corresponding groove 17 would be formed on the sleeve 9.

[046] Il est notable que le capuchon est configuré pour que le couple nécessaire à provoquer le mouvement de l’embout de distribution en tournant le corps 6 est inférieur, et de préférence largement inférieur, au couple nécessaire pour dévisser le capuchon du col. Cela évite tout dévissage involontaire du capuchon, mais permet néanmoins d’ôter le capuchon en poursuivant le dévissage, avec un couple plus important, une fois l’embout de distribution amené en position levée. [046] It is notable that the cap is configured so that the torque required to cause the dispensing tip to move by turning the body 6 is less, and preferably much less, than the torque required to unscrew the cap from the neck. This prevents any involuntary unscrewing of the cap, but nevertheless allows the cap to be removed by continuing to unscrew it, with greater torque, once the dispensing tip has been brought into the raised position.

[047] Comme on le voit notamment à la figure 4, l’embout de distribution forme un canal 15, qui est libre de tout obstacle et qui permet le passage du produit du réservoir 2 à l’orifice de distribution 8. [047] As can be seen in particular in Figure 4, the dispensing nozzle forms a channel 15, which is free of any obstacle and which allows the product to pass from the reservoir 2 to the dispensing orifice 8.

[048] Au contraire des flacons comportant une pompe dans lesquels la pompe est fixement montée sur le col et dans lesquels il est aisé d’assurer l’étanchéité entre le col et la pompe d’une part, et dans lesquels la pompe forme un espace étanche d’autre part, il est nécessaire dans le cadre de la présente invention d’assurer une étanchéité entre le col et une pièce mobile, à savoir l’embout de distribution. Cependant, le col des flacons, notamment des flacons de verrerie, peut présenter des dispersions dimensionnelles et géométriques significatives. Cette problématique est résolue dans l’invention en dotant le manchon 9 d’une portion d’étanchéité 18. [048] Unlike bottles comprising a pump in which the pump is fixedly mounted on the neck and in which it is easy to ensure a seal between the neck and the pump on the one hand, and in which the pump forms a sealed space on the other hand, it is necessary in the context of the present invention to ensure a seal between the neck and a moving part, namely the dispensing tip. However, the neck of bottles, in particular glass bottles, may have significant dimensional and geometric dispersions. This problem is resolved in the invention by providing the sleeve 9 with a sealing portion 18.

[049] La portion d’étanchéité 18 s’étend longitudinalement à l’intérieur du col 4. La portion d’étanchéité comporte une surface intérieure 19 dont la géométrie et les dimensions peuvent être réalisés avec de très faibles tolérances. Par exemple, le manchon 9 peut être réalisé en matériau plastique injecté, ce qui assure de faibles tolérances dimensionnelles. Tout autre procédé de fabrication offrant une faible tolérance et peu de dispersions peut être utilisé pour réaliser le manchon 9. Alternativement ou en complément, la surface intérieure 19 peut être rectifiée par usinage. [049] The sealing portion 18 extends longitudinally inside the neck 4. The sealing portion has an inner surface 19 whose geometry and dimensions can be produced with very small tolerances. For example, the sleeve 9 can be made of injected plastic material, which ensures small dimensional tolerances. Any other manufacturing method offering a small tolerance and little dispersion can be used to produce the sleeve 9. Alternatively or in addition, the inner surface 19 can be ground by machining.

[050] La portion d’étanchéité s’étend sur une certaine longueur du col 4, par exemple sur au moins 2 mm, voire sur au moins 5 mm. [050] The sealing portion extends over a certain length of the neck 4, for example over at least 2 mm, or even over at least 5 mm.

[051] La surface intérieure 19 forme donc une surface de géométrie connue et maitrisée, vis-à-vis de laquelle il est possible de former et de garantir une étanchéité aux liquide. [051] The inner surface 19 therefore forms a surface of known and controlled geometry, with respect to which it is possible to form and guarantee a seal against liquids.

[052] Ainsi, l’embout de distribution 7 comporte une partie inférieure 20 qui est montée coulissante longitudinalement dans la portion d’étanchéité 18. L’étanchéité peut être obtenue par le faible jeu, voir le contact, entre la portion d’étanchéité et une surface, à savoir dans l’exemple représenté la surface extérieure, de partie inférieure 20 de l’embout de distribution 7. Pour cela, la partie inférieure 20 de l’embout de distribution 7 peut être cylindrique, de section transversale correspondant, à un faible jeu fonctionnel près, à la section transversale intérieure de la portion d’étanchéité 18. [052] Thus, the dispensing nozzle 7 comprises a lower part 20 which is mounted to slide longitudinally in the sealing portion 18. The sealing can be obtained by the small clearance, or even the contact, between the sealing portion and a surface, namely in the example shown the outer surface, of lower part 20 of the distribution nozzle 7. For this, the lower part 20 of the distribution nozzle 7 can be cylindrical, with a cross section corresponding, with a small functional clearance, to the inner cross section of the sealing portion 18.

[053] Avantageusement, la partie inférieure 20 est plus longue que la portion d’étanchéité 18. En particulier, la partie inférieure 20 s’étend longitudinalement au-delà de la portion d’étanchéité 18, tant dans la position baissée que dans la position levée de l’embout de distribution. Ainsi, l’étanchéité peut être réalisée sur toute la longueur (c’est-à-dire la dimension longitudinale) de la portion d’étanchéité 18. [053] Advantageously, the lower part 20 is longer than the sealing portion 18. In particular, the lower part 20 extends longitudinally beyond the sealing portion 18, both in the lowered position and in the raised position of the dispensing nozzle. Thus, sealing can be achieved over the entire length (i.e. the longitudinal dimension) of the sealing portion 18.

[054] En alternative à cette étanchéité réalisée entre deux surfaces correspondantes, d’autres moyens de la réaliser peuvent être utilisés comme expliqué ci-après. [054] As an alternative to this sealing produced between two corresponding surfaces, other means of producing it can be used as explained below.

[055] La figure 5 illustre une valve optionnelle pouvant être utilisée dans certains modes de réalisation de l’invention. La valve 21 est positionnée au niveau de la sortie de l’embout de distribution 7, et forme alors l’orifice de distribution 8. La valve 21 peut être réalisée en matériau souple, par exemple en silicone. Elle empêche l’écoulement du produit lorsque l’embout de distribution est en position baissée. Par exemple, la surface de sortie 22 de la valve est alors au contact de la surface intérieure du corps 6, ce qui empêche toute sortie de produit. [055] Figure 5 illustrates an optional valve that can be used in certain embodiments of the invention. The valve 21 is positioned at the outlet of the dispensing tip 7, and then forms the dispensing orifice 8. The valve 21 can be made of a flexible material, for example silicone. It prevents the flow of the product when the dispensing tip is in the lowered position. For example, the outlet surface 22 of the valve is then in contact with the inner surface of the body 6, which prevents any product from escaping.

[056] Le mode de réalisation des figures 6 et 7 est essentiellement identique à celui des figures 1 à 5, à la différence près que ce mode de réalisation ne comporte pas de valve en sortie de l’embout de distribution. Dès lors, l’orifice de distribution peut avoir une section calibrée, selon la nature du produit contenu dans le flacon, pour assurer une distribution avec un débit ni trop faible ni trop fort. Dans l’exemple présenté, la section de l’orifice de distribution est rectangulaire, de sorte que cette section peut être relativement importante malgré une faible levée de l’embout de distribution. La sortie inopinée de produit est évitée par un bon ajustement entre la surface intérieure du corps 6 et l’embout de distribution 7. Optionnellement, un élément souple, par exemple en élastomère, peut être positionné la face interne du corps 6 en regard de l’orifice de distribution lorsque l’embout de distribution est en position baissée. Cet élément souple permet alors de parfaire l’étanchéité au niveau de l’orifice de distribution, lorsque le flacon est fermé. [056] The embodiment of Figures 6 and 7 is essentially identical to that of Figures 1 to 5, except that this embodiment does not include a valve at the outlet of the dispensing nozzle. Therefore, the dispensing orifice can have a calibrated section, depending on the nature of the product contained in the bottle, to ensure dispensing with a flow rate that is neither too low nor too high. In the example presented, the section of the dispensing orifice is rectangular, so that this section can be relatively large despite a low lift of the dispensing nozzle. The unexpected exit of product is avoided by a good fit between the inner surface of the body 6 and the dispensing nozzle 7. Optionally, a flexible element, for example made of elastomer, can be positioned on the inner face of the body 6 opposite the dispensing orifice when the dispensing nozzle is in the lowered position. This flexible element then makes it possible to perfect the seal at the dispensing orifice, when the bottle is closed.

[057] Le mode de réalisation de la figure 8 et de la figure 9 se distingue quant à lui de ceux des figures 1 à 7 essentiellement par le mécanisme permettant de passer de la position baissée à la position levée (et inversement) de l’embout de distribution. Sur ces figures, seul le capuchon 5 est représenté, le réservoir du flacon étant par ailleurs analogue à celui des modes de réalisation précédemment décrits. [057] The embodiment of Figure 8 and Figure 9 differs from those of Figures 1 to 7 essentially by the mechanism allowing the dispensing tip to move from the lowered position to the raised position (and vice versa). In these figures, only the cap 5 is shown, the reservoir of the bottle being otherwise similar to that of the embodiments previously described.

[058] La figure 8 est une vue en coupe, selon un plan équivalent à celui des figures 4 [059] Sur la figure 9, le corps 6 du capuchon 5 est représenté en transparence afin de montrer en partie le mécanisme du capuchon. [058] Figure 8 is a sectional view, along a plane equivalent to that of Figures 4 [059] In Figure 9, the body 6 of the cap 5 is shown in transparency in order to partially show the mechanism of the cap.

[060] Le capuchon comporte, comme dans les modes de réalisation déjà présentés, un manchon 9 destiné à être monté fixe sur le col d’un réservoir, par exemple par vissage, un corps 5 monté rotatif sur le manchon 9, et un embout de distribution 7 qui forme un canal 15 permettant le passage du produit depuis le réservoir jusqu’à l’orifice de distribution 8. Ici, l’orifice de distribution 8 ne comporte pas de valve, mais il pourrait tout à fait en comporter une. [060] The cap comprises, as in the embodiments already presented, a sleeve 9 intended to be mounted fixedly on the neck of a reservoir, for example by screwing, a body 5 rotatably mounted on the sleeve 9, and a dispensing nozzle 7 which forms a channel 15 allowing the passage of the product from the reservoir to the dispensing orifice 8. Here, the dispensing orifice 8 does not comprise a valve, but it could quite easily comprise one.

[061] Comme les modes de réalisation déjà présentés l’embout de distribution 7 comporte un pion 11 qui est engagé dans un guide longitudinal 12 et dans une rampe 13. [061] Like the embodiments already presented, the distribution tip 7 comprises a pin 11 which is engaged in a longitudinal guide 12 and in a ramp 13.

[062] Néanmoins dans ce mode de réalisation, le guide longitudinal 12 est formé dans l’épaisseur du corps 6, sur sa surface intérieure. La rampe 13 est formée au travers du manchon 9. [062] Nevertheless, in this embodiment, the longitudinal guide 12 is formed in the thickness of the body 6, on its inner surface. The ramp 13 is formed through the sleeve 9.

[063] Dès lors, lors de la rotation du corps 6, le pion 11 est lui aussi entraîné en rotation. Néanmoins, pour des raisons esthétiques et pratiques, il peut être souhaitable que l’embout de distribution passe de la position baissée à la position levée selon un mouvement de translation pure. Pour cela, dans le mode de réalisation des figures 8 et 9 l’embout de distribution est réalisé en deux parties distinctes, à savoir la partie inférieure 20 et une partie supérieure 22. [063] Therefore, when the body 6 rotates, the pin 11 is also rotated. However, for aesthetic and practical reasons, it may be desirable for the dispensing nozzle to move from the lowered position to the raised position using a pure translational movement. For this, in the embodiment of Figures 8 and 9 the dispensing nozzle is made in two separate parts, namely the lower part 20 and an upper part 22.

[064] La partie inférieure 20 et la partie supérieure 22 sont montées libres en rotation l’une par rapport à l’autre selon un axe longitudinal. Dans l’exemple représenté, une protrusion annulaire 23 de la partie inférieure est engagée dans une gorge annulaire 24 correspondante de la partie supérieure 22, ce qui permet la rotation entre ces deux parties. [064] The lower part 20 and the upper part 22 are mounted to rotate freely relative to each other along a longitudinal axis. In the example shown, an annular protrusion 23 of the lower part is engaged in a corresponding annular groove 24 of the upper part 22, which allows rotation between these two parts.

[065] Afin de bloquer la partie supérieure 22 en rotation, celle-ci est dotée d’une butée 25, ici sous la forme d’une arête longitudinale, cette butée 25 étant introduite dans une fente longitudinale 26 formée dans le manchon 9. Ainsi, lorsque le corps 6 du capuchon est tourné, la partie inférieure 20 de l’embout de distribution se déplace longitudinalement en tournant, du fait de la progression du (ou des) pion 11 dans la (ou les) rampe 13, tandis que la partie supérieure 22, boquée en rotation vis-à-vis du manchon 9, a un mouvement de translation pure. [065] In order to block the upper part 22 in rotation, the latter is provided with a stop 25, here in the form of a longitudinal edge, this stop 25 being introduced into a longitudinal slot 26 formed in the sleeve 9. Thus, when the body 6 of the cap is turned, the lower part 20 of the dispensing nozzle moves longitudinally while turning, due to the progression of the pin(s) 11 in the ramp(s) 13, while the upper part 22, blocked in rotation with respect to the sleeve 9, has a pure translational movement.

[066] Un autre aspect est illustré à la figure 8. Ainsi, dans le dispositif de la figure 8, la portion d’étanchéité 18 comporte une partie extrémale amincie. Ici, la partie extrémale amincie comporte un chanfrein formé du côté de la paroi du col du réservoir du flacon. La portion d’étanchéité 18 est légèrement conique, ou resserrée au niveau de la partie extrémale amincie. Cette partie extrémale amincie est au contact de la partie inférieure 20 de l’embout de distribution 7, ce qui assure une étanchéité le long de la ligne de contact (ou de la surface de contact qui a une faible longueur). La souplesse de la portion amincie assure son ajustement au contact de la partie inférieure 20. On peut alors parler d’une étanchéité linéique. Le cas échéant, la partie extrémale amincie peut former une lèvre au contact de la partie inférieure 20. [066] Another aspect is illustrated in Figure 8. Thus, in the device of Figure 8, the sealing portion 18 comprises a thinned end portion. Here, the thinned end portion comprises a chamfer formed on the side of the wall of the neck of the bottle reservoir. The sealing portion 18 is slightly conical, or narrowed at the level of the thinned end portion. This thinned end portion is in contact with the lower part 20 of the dispensing nozzle 7, which ensures a seal along the contact line (or the contact surface which has a short length). The flexibility of the thinned portion ensures its adjustment in contact with the lower part 20. We can then speak of a linear seal. If necessary, the thinned end part can form a lip in contact with the lower part 20.

[067] Dans un mode de réalisation alternatif, un ou plusieurs joints annulaires peuvent être interposés entre l’embout de distribution 7 et la partie d’étanchéité 18. [067] In an alternative embodiment, one or more annular seals may be interposed between the dispensing nozzle 7 and the sealing portion 18.

[068] La figure 10 représente un autre mode de réalisation de l’invention. Tout comme dans les modes de réalisation représentés notamment en référence aux figures 1 à 7, le capuchon 5 est fixé sur le col 4, via un manchon 9 par exemple vissé sur le col 4. Le capuchon[068] Figure 10 represents another embodiment of the invention. Just as in the embodiments represented in particular with reference to Figures 1 to 7, the cap 5 is fixed on the neck 4, via a sleeve 9 for example screwed onto the neck 4. The cap

5 peut aussi avoir dans ce mode de réalisation l’apparence d’un bouchon à vis classique. 5 can also have in this embodiment the appearance of a classic screw cap.

[069] Tout comme dans les modes de réalisation précédents, le capuchon 5 comporte un corps 6 qui forme sa paroi latérale extérieure. Une rotation du corps 6, de préférence dans le sens classique d’un dévissage, c’est-à-dire en sens antihoraire, entraine la sortie de l’embout de distribution 7. L’embout de distribution 7 comporte un orifice de distribution 8 orienté transversalement, perpendiculairement à la direction longitudinale. La rotation du corps[069] As in the previous embodiments, the cap 5 comprises a body 6 which forms its outer side wall. A rotation of the body 6, preferably in the conventional direction of unscrewing, i.e. counterclockwise, causes the dispensing tip 7 to come out. The dispensing tip 7 comprises a dispensing orifice 8 oriented transversely, perpendicular to the longitudinal direction. The rotation of the body

6 permet de faire passer l’embout de distribution 7 de sa position baissée dans laquelle l’orifice de distribution est obturé à sa position levée dans laquelle l’orifice de distribution est libéré pour permettre la distribution du produit contenu dans le réservoir. L’orifice de distribution peut comporter une valve d’étanchéité. 6 allows the dispensing nozzle 7 to move from its lowered position in which the dispensing orifice is closed to its raised position in which the dispensing orifice is released to allow the dispensing of the product contained in the reservoir. The dispensing orifice may include a sealing valve.

[070] Le mécanisme permettant de transformer la rotation du corps 6 en une translation (simple ou combinée à une rotation) de l’embout de distribution est similaire aux mécanismes décrits pour les modes de réalisation précédents. [070] The mechanism for transforming the rotation of the body 6 into a translation (simple or combined with a rotation) of the dispensing tip is similar to the mechanisms described for the previous embodiments.

[071] Comparativement aux modes de réalisation précédemment décrits, le manchon 9 comporte une colonne 27 longitudinale. La colonne 27 est creuse et comporte, à son extrémité supérieure 28 une ouverture transversale 29. [071] Compared to the embodiments previously described, the sleeve 9 comprises a longitudinal column 27. The column 27 is hollow and comprises, at its upper end 28, a transverse opening 29.

[072] La colonne 27 s’étend au moins en partie, longitudinalement, dans le col 4. [072] Column 27 extends at least partly, longitudinally, in neck 4.

[073] L’ embout de distribution 7 comporte un tube 30 longitudinal dans lequel est montée la colonne 27, la colonne 27 pouvant coulisser longitudinalement dans le tube 30. Le tube 30 comporte une lumière 31 transversale, qui débouche dans un volume périphérique 32. Le volume périphérique 32 est lié fluidiquement à l’orifice de distribution 8. [073] The dispensing nozzle 7 comprises a longitudinal tube 30 in which the column 27 is mounted, the column 27 being able to slide longitudinally in the tube 30. The tube 30 comprises a transverse lumen 31, which opens into a peripheral volume 32. The peripheral volume 32 is fluidically linked to the dispensing orifice 8.

[074] Lorsque l’embout de distribution 7 est dans sa position baissée, l’ouverture transversale 29 est en regard d’une paroi de du tube 30. Lorsque l’embout de distribution 7 est en position levée, l’ouverture transversale 7 est en regard de la lumière 31 , permettant le passage du produit contenu dans le réservoir dans le volume périphérique 32 et finalement vers l’orifice de distribution 8. [074] When the dispensing nozzle 7 is in its lowered position, the transverse opening 29 faces a wall of the tube 30. When the dispensing nozzle 7 is in the raised position, the transverse opening 7 faces the light 31, allowing the passage of the product contained in the reservoir into the peripheral volume 32 and finally towards the dispensing orifice 8.

[075] Une portion d’étanchéité 18 est formé en partie basse de la colonne 27 du manchon 9, c’est-à-dire sur la partie du manchon 9 située en tout ou partie dans le col 4. La paroi de la colonne 27 forme ainsi à ce niveau une surface intérieure 19. La surface intérieure 19 correspond à la surface externe de la colonne, qui est à l’intérieur vis-à-vis du reste du manchon. [075] A sealing portion 18 is formed in the lower part of the column 27 of the sleeve 9, that is to say on the part of the sleeve 9 located wholly or partly in the neck 4. The wall of the column 27 thus forms at this level an interior surface 19. The interior surface 19 corresponds to the external surface of the column, which is inside with respect to the rest of the sleeve.

[076] Une étanchéité est formée entre la portion d’étanchéité 18 du manchon 9 et la surface correspondante située en partie inférieure du tube 30 de l’embout de distribution 7. Cette étanchéité peut être réalisée notamment de toutes les manières précitées en référence aux modes de réalisation précédemment décrits. [076] A seal is formed between the sealing portion 18 of the sleeve 9 and the corresponding surface located in the lower part of the tube 30 of the dispensing nozzle 7. This seal can be achieved in particular in all the ways mentioned above with reference to the embodiments previously described.

[077] L’ un des avantages du mode de réalisation de la figure 10 réside dans le fait que dans le capuchon 5, le volume dans lequel le produit peut se trouver reste constant, que l’embout de distribution 7 soit en position baisée ou en position levée. Cela évite tout risque de sortie involontaire de produit lorsque l’embout de distribution 7 est ramenée en position baissé. [077] One of the advantages of the embodiment of Figure 10 lies in the fact that in the cap 5, the volume in which the product can be located remains constant, whether the dispensing tip 7 is in the lowered position or in the raised position. This avoids any risk of involuntary egress of product when the dispensing tip 7 is returned to the lowered position.

[078] Les différentes façons décrites ci-dessus d’obtenir l’étanchéité souhaitée peuvent être appliquées aux différents modes de réalisation du mécanisme. [078] The different ways described above of obtaining the desired sealing can be applied to the different embodiments of the mechanism.

[079] Il est ainsi proposé dans le cadre de la présente invention un flacon pour un produit liquide ou visqueux, tel qu’un gel lavant ou une crème corporelle, dont l’embout de distribution est levé ou baissé, afin de libérer ou au contraire de masquer et obturer l’orifice de distribution, c’est-à-dire afin d’ouvrir ou fermer le flacon. Cette cinématique d’ouverture et de fermeture est intuitive (car le capuchon ressemble à un bouchon à vis classique, et s’ouvre et se ferme par rotation) et plaisante. L’invention permet de régler les problèmes d’étanchéité pouvant exister du fait des dispersions dans la fabrication du réservoir, qui peut être en verre ou réalisé en matériau plastique avec des tolérances relativement grandes. [079] Thus, within the framework of the present invention, a bottle for a liquid or viscous product, such as a washing gel or a body cream, is proposed, the dispensing tip of which is raised or lowered, in order to free or, on the contrary, to mask and close the dispensing orifice, that is to say, in order to open or close the bottle. This opening and closing kinematics is intuitive (because the cap resembles a conventional screw cap, and opens and closes by rotation) and pleasant. The invention makes it possible to resolve the sealing problems that may exist due to dispersions in the manufacture of the reservoir, which may be made of glass or made of plastic material with relatively large tolerances.
