Description

La présente invention concerne un flacon du type comportant d'une part une partie formant réservoir comprenant un col fileté se raccordant à un corps réalisé par soufflage, et d'autre part un bouchon comprenant une capsule intérieure d'étanchéité à visser sur le col et un capot extérieur fixé sur cette capsule intérieure.The present invention relates to a bottle of the type comprising on the one hand a reservoir part comprising a threaded neck connecting to a body made by blowing, and on the other hand a stopper comprising an inner capsule seal to be screwed on the neck and an outer cover fixed on this inner capsule.

L'invention concerne plus particulièrement un flacon dont la partie formant réservoir est réalisée en deux temps, à savoir une première étape dans laquelle on réalise par moulage le col fileté d'un seul tenant avec une paraison, puis une deuxième étape dans laquelle on réalise le corps de la partie formant réservoir par soufflage de la paraison.The invention relates more particularly to a bottle, the part of which forming a reservoir is carried out in two stages, namely a first step in which is carried out by molding the threaded neck in one piece with a parison, then a second step in which the body of the reservoir portion is produced by blowing the parison.

Le soufflage a lieu dans un moule différent de celui ayant servi à réaliser la paraison.The blowing takes place in a mold different from that used to make the parison.

Lorsque le corps de la partie formant réservoir et le bouchon présentent des formes extérieures non symétriques de révolution, par exemple des sections transversales polygonales, il est souhaitable pour des raisons esthétiques qu'en position de fermeture du flacon le bouchon se trouve dans une position angulaire prédéterminée par rapport audit corps.When the body of the reservoir portion and the cap have non-symmetrical external shapes of revolution, for example sections transverse polygonal, it is desirable for aesthetic reasons that bottle closed position the cap is in an angular position predetermined with respect to said body.

La demande de brevet européen EP 0 004 501 décrit un dispositif de bouchage pour un récipient à goulot fileté. Le dispositif de bouchage comporte un capuchon solidarisé à un enjoliveur externe. Des surfaces de butée radiales coopérantes sont prévues sur le flacon et l'enjoliveur.European patent application EP 0 004 501 describes a closure device for a threaded neck container. The stopper has a cap secured to an external hubcap. Cooperating radial abutment surfaces are provided on the bottle and the hubcap.

On a proposé dans la demande de brevet européen EP-A-007 274 de réaliser le capot extérieur avec une surface d'arrêt propre à coopérer avec une butée d'orientation formée sur le col pour immobiliser le bouchon dans une position angulaire prédéterminée par rapport au corps du flacon au terme du vissage du bouchon. Une pièce d'arrêt est insérée dans le capot extérieur pour constituer cette surface d'arrêt.European patent application EP-A-007 274 has proposed make the outer cover with a stop surface suitable for cooperating with a stop orientation formed on the neck to immobilize the stopper in a position predetermined angular with respect to the body of the bottle at the end of the screwing of the plug. A stopper is inserted in the outer cover to constitute this stop surface.

On connaít par ailleurs par la demande de brevet européen EP-A-179 706 un flacon comportant un col fileté pourvu d'une butée d'orientation et d'un bossage d'anti-dévissabilité réalisés sur le col.We also know by European patent application EP-A-179 706 a bottle having a threaded neck provided with an orientation stop and a boss of anti-unscrewing carried out on the collar.

La société demanderesse a constaté que dans les flacons connus, malgré la présence de la butée d'orientation sur le col de la partie formant réservoir du flacon, il subsiste parfois un léger décalage angulaire, de l'ordre de quelques degrés par rapport à la position recherchée.The applicant company has found that in the known bottles, despite the presence of the orientation stop on the neck of the reservoir portion of the bottle, there is sometimes a slight angular offset, of the order of a few degrees relative to the desired position.

Ce décalage qui est peu perceptible lorsque le capot extérieur est de taille modeste devient gênant lorsque le bouchon présente une forme allongée transversalement.This discrepancy, which is hardly noticeable when the outer cover is large modest becomes annoying when the cap has an elongated shape transversely.

La présente invention vise à proposer un nouveau flacon permettant d'obtenir à la fois une fermeture étanche et un positionnement satisfaisant du bouchon en position de fermeture, même lorsque ce dernier présente une forme allongée transversalement.The present invention aims to provide a new bottle allowing to obtain both a tight closure and a satisfactory positioning of the cap in closed position, even when the latter has a shape elongated transversely.

Le flacon selon l'invention est du type comportant une partie formant réservoir comprenant un col fileté se raccordant à un corps réalisé par soufflage et un bouchon comprenant une capsule intérieure d'étanchéité à visser sur le col et un capot extérieur fixé sur la capsule intérieure, la partie formant réservoir comportant au moins une butée d'orientation et le bouchon au moins une surface d'arrêt propre à coopérer avec cette butée d'orientation afin d'immobiliser en rotation le bouchon dans une position angulaire prédéterminée par rapport au corps de la partie formant réservoir au terme du vissage du bouchon, et se caractérise par le fait que la butée d'orientation est réalisée par soufflage avec le corps de la partie formant réservoir.The bottle according to the invention is of the type comprising a part forming reservoir comprising a threaded neck connecting to a body made by blowing and a cap including an inner sealing capsule to be screwed on the neck and a cover attached to the inner capsule, the reservoir portion comprising at minus an orientation stop and the plug at least one stop surface suitable for cooperate with this orientation stop in order to immobilize the plug in rotation in a predetermined angular position relative to the body of the forming part tank at the end of the screwing of the cap, and is characterized by the fact that the stop orientation is achieved by blowing with the body of the tank portion.

Grâce à l'invention, il est possible d'obtenir de manière fiable un positionnement précis du bouchon par rapport au corps de la partie formant réservoir et de remédier à l'inconvénient mentionné ci-dessus.Thanks to the invention, it is possible to reliably obtain a precise positioning of the cap relative to the body of the reservoir portion and remedy the above mentioned drawback.

L'invention repose sur la constatation que dans les flacons connus, dont le corps est réalisé par soufflage, l'orientation du col par rapport au moule servant au soufflage de la paraison est susceptible de varier légèrement lors du transport de la paraison d'un moule à l'autre.The invention is based on the observation that in known bottles, of which the body is produced by blowing, the orientation of the neck relative to the mold used for Parison blowing may vary slightly when transporting the parison from one mold to another.

C'est cette imprécision concernant le positionnement angulaire du col par rapport au corps de la partie formant réservoir qui est responsable du léger décalage angulaire observé par la demanderesse.It is this imprecision concerning the angular positioning of the cervix by relation to the body of the tank part which is responsible for the slight offset angular observed by the plaintiff.

La réalisation dans l'invention de la butée d'orientation lors du soufflage du corps de la partie formant réservoir garantit un positionnement angulaire précis de la butée d'orientation par rapport audit corps et donc un positionnement précis du bouchon en position de fermeture.The embodiment in the invention of the orientation stop during blowing of the body of the reservoir part guarantees precise angular positioning of the orientation stop relative to said body and therefore precise positioning of the plug in closed position.

Dans une réalisation préférée de l'invention, la surface d'arrêt est réalisée dans l'épaisseur d'une jupe tubulaire moulée d'un seul tenant avec le capot extérieur, cette jupe tubulaire étant de préférence démoulée vers le bas, c'est-à-dire vers l'extrémité destinée à être dirigée vers le corps de la partie formant réservoir.In a preferred embodiment of the invention, the stop surface is produced in the thickness of a tubular skirt molded in one piece with the outer cover, this tubular skirt being preferably demolded downwards, that is to say towards the end intended to be directed towards the body of the tank-forming part.

La fabrication du bouchon s'en trouve simplifiée puisque, à la différence de celui décrit dans la demande EP-A-007 274, il n'est pas nécessaire de rapporter une pièce d'arrêt dans le capot extérieur.The manufacture of the cap is thereby simplified since, unlike from that described in application EP-A-007 274, it is not necessary to report a stopper in the outer cover.

La jupe tubulaire précitée peut être une jupe extérieure du capot extérieur ou en variante une jupe intérieure, pouvant servir à la fixation du capot extérieur sur la capsule intérieure d'étanchéité.The aforementioned tubular skirt can be an outer skirt of the outer cover or alternatively an inner skirt, which can be used to fix the outer cover to the inner sealing capsule.

Avantageusement, le capot extérieur comporte un bossage d'anti-dévissabilité, ce bossage étant apte à franchir élastiquement la butée d'orientation avant que la surface d'arrêt ne vienne en appui sur cette dernière, au terme du vissage du bouchon.Advantageously, the outer cover includes an anti-unscrewability boss, this boss being able to elastically cross the orientation stop before the stop surface comes to bear on the latter, at the end of the screwing of the plug.

Avantageusement, le bouchon comporte à son extrémité inférieure une bague rapportée sur le capot extérieur, destinée à cacher l'extrémité inférieure de la jupe tubulaire sur laquelle est réalisée la surface d'arrêt.Advantageously, the plug has at its lower end a ring attached to the outer cover, intended to hide the lower end of the tubular skirt on which the stop surface is made.

Cette bague comporte avantageusement des inscriptions sur sa surface extérieure, inscriptions qu'il serait, le cas échéant, difficile de faire figurer directement sur le capot extérieur compte tenu de sa géométrie. Elle peut aussi avoir une couleur différente de celle du capot extérieur.This ring advantageously has inscriptions on its surface exterior, inscriptions which it would be difficult, if necessary, to include directly on the outer cover given its geometry. She can also have a different color from that of the outer cover.

De préférence, la butée d'orientation se situe dans un plan de joint du corps de la partie formant réservoir.Preferably, the orientation stop is located in a joint plane of the body of the reservoir portion.

Ce corps peut être réalisé en matière plastique ou en verre.This body can be made of plastic or glass.

Le flacon peut comporter deux butées d'orientation diamétralement opposées par rapport au col.The bottle may have two diametrically oriented stops opposite to the collar.

Le capot extérieur peut comporter deux surfaces d'arrêt et deux bossages d'anti-dévissabilité. The outer cover may have two stop surfaces and two bosses anti-unscrewing.

Avantageusement, la capsule intérieure est réalisée dans une matière plastique semi-rigide, telle que du polypropylène copolymère.Advantageously, the inner capsule is made of a material semi-rigid plastic, such as polypropylene copolymer.

Avantageusement, le capot extérieur est réalisé dans une matière plastique présentant un module d'élasticité en traction supérieur ou égal à 100 MPa (kg.f/mm2), de préférence une matière thermoplastique ou thermodurcissable.Advantageously, the outer cover is made of a plastic material having a tensile elasticity module greater than or equal to 100 MPa (kg.f / mm 2 ), preferably a thermoplastic or thermosetting material.

L'invention a encore pour objet un procédé de fabrication d'un flacon, comportant les étapes consistant à :

  • réaliser un col par moulage avec une paraison, puis
  • réaliser par soufflage de la paraison le corps de la partie formant réservoir avec au moins une butée d'orientation à proximité du col.
The subject of the invention is also a method of manufacturing a bottle, comprising the steps consisting in:
  • make a neck by molding with a parison, then
  • make the body of the reservoir part by blowing the parison with at least one orientation stop near the neck.

Après réalisation de la partie formant réservoir, cette dernière peut être remplie avec un liquide tel qu'un parfum, puis fermée au moyen d'un bouchon comportant une capsule intérieure d'étanchéité et un capot extérieur pourvu d'au moins une surface d'arrêt propre à coopérer avec la butée d'orientation.After completion of the tank portion, the latter can be filled with a liquid such as a perfume, then closed with a stopper comprising an inner sealing capsule and an outer cover provided with minus a clean stop surface to cooperate with the orientation stop.

Le capot extérieur est de préférence rapporté sur la capsule intérieure d'étanchéité après vissage de cette dernière sur le col.The outer cover is preferably attached to the inner capsule sealing after screwing the latter onto the neck.

Le capot extérieur est avantageusement réalisé par moulage de matière plastique en étant démoulé uniquement par le bas, la surface d'arrêt étant réalisée dans l'épaisseur d'une jupe tubulaire.The outer cover is advantageously made by molding of material plastic by being unmolded only from below, the stop surface being produced in the thickness of a tubular skirt.

D'autres caractéristiques et avantages de la présente invention ressortiront à la lecture de la description détaillée qui va suivre, d'exemples non limitatifs de mise en oeuvre, et à l'examen du dessin annexé sur lequel :

Le flacon 1 représenté sur la figure 1 comporte une partie formant réservoir 9 et un bouchon 4.The bottle 1 shown in Figure 1 has a portion forming tank 9 and a cap 4.

La partie formant réservoir 9 comprend un corps 2 surmonté d'un col fileté 3 d'axe X, sur lequel peut venir se visser le bouchon 4.The reservoir portion 9 comprises a body 2 surmounted by a neck threaded 3 of axis X, onto which the plug 4 can be screwed.

Ce dernier est composé d'une capsule intérieure d'étanchéité 5, d'un capot extérieur 6 fixé sur la capsule d'étanchéité intérieure 5, et d'une bague métallique 12 rapportée à l'extrémité inférieure du capot extérieur 6.The latter is composed of an inner sealing capsule 5, a cover outer 6 fixed on the inner sealing capsule 5, and a metal ring 12 attached to the lower end of the outer cover 6.

La partie formant réservoir 9 est réalisée en verre ou en matière plastique rigide ou semi-rigide, en deux étapes.The tank portion 9 is made of glass or plastic rigid or semi-rigid, in two stages.

On commence par réaliser le col 3 avec une paraison puis on souffle la paraison pour former le corps 2, de façon connue en soi.We start by making the collar 3 with a parison then we blow the parison to form the body 2, in a manner known per se.

Le corps 2 est réalisé, dans l'exemple décrit, avec une section transversale sensiblement rectangulaire définissant deux faces principales 10 sensiblement planes et parallèles et deux épaules 13 de chaque côté du col 3 en partie supérieure du corps 2.The body 2 is produced, in the example described, with a cross section substantially rectangular defining two main faces 10 substantially planar and parallel and two shoulders 13 on each side of the neck 3 in the upper part of the body 2.

Le plan de joint 11 du corps 2 s'étend selon une diagonale du flacon, comme représenté.The joint plane 11 of the body 2 extends along a diagonal of the bottle, as shown.

Le capot extérieur 6 est réalisé par moulage de matière plastique, de même que la capsule intérieure d'étanchéité 5.The outer cover 6 is made by molding plastic material, same as the inner sealing capsule 5.

Deux butées d'orientation 15, dont seule l'une est visible sur la figure 1, diamétralement opposées par rapport à l'axe X du col 3 et situées dans le plan de joint 11, sont réalisées sur les épaules 13 du flacon à proximité du col 3, lors du soufflage du corps 2.Two orientation stops 15, only one of which is visible in FIG. 1, diametrically opposite with respect to the X axis of the neck 3 and located in the plane of seal 11, are made on the shoulders 13 of the bottle near the neck 3, during the body blowing 2.

Ainsi, le positionnement de ces butées d'orientation 15 sur le corps 2 est constant.Thus, the positioning of these orientation stops 15 on the body 2 is constant.

Dans une variante non illustrée, une seule butée d'orientation 15 est réalisée sur le corps 2.In a variant not illustrated, a single orientation stop 15 is performed on the body 2.

Le capot 6 présente en partie supérieure 20 une forme allongée selon un axe Y s'étendant perpendiculairement à l'axe X.The cover 6 has in the upper part 20 an elongated shape according to a Y axis extending perpendicular to the X axis.

On souhaite que l'axe Y soit parallèle aux faces principales 10 du corps 2 lorsque le flacon est fermé. We want the Y axis to be parallel to the main faces 10 of the body 2 when the bottle is closed.

Le capot extérieur 6 comporte en partie inférieure 21 comme on peut le voir sur la figure 2, une jupe extérieure 22 et une jupe intérieure 23 cylindriques et coaxiales, réalisées d'un seul tenant par moulage de matière plastique avec la partie supérieure 20.The outer cover 6 has at the bottom 21 as can be seen. see in Figure 2, an outer skirt 22 and an inner skirt 23 cylindrical and coaxial, made in one piece by plastic molding with the part upper 20.

La jupe intérieure 23 présente une section transversale sensiblement circulaire et sert à la fixation du capot extérieur 6 sur la capsule intérieure d'étanchéité 5, laquelle présente de préférence sur sa périphérie des stries d'axe X destinées à solidariser par friction la capsule intérieure 5 avec le capot extérieur 6.The inner skirt 23 has a substantially cross section circular and used for fixing the outer cover 6 to the inner capsule seal 5, which preferably has on its periphery grooves of axis X intended to frictionally secure the inner capsule 5 with the outer cover 6.

La jupe extérieure 22 présente dans l'exemple décrit une section transversale sensiblement carrée, la jupe intérieure 23 rejoignant en quatre emplacements 24 de sa périphérie la surface intérieure des quatre côtés de la jupe extérieure 22 et ménageant avec les quatre angles intérieurs de la jupe extérieure 22 des cavités 25.The outer skirt 22 present in the example describes a section substantially square transverse, the inner skirt 23 joining in four locations 24 of its periphery the inner surface of the four sides of the skirt outer 22 and sparing with the four inner angles of the outer skirt 22 cavities 25.

L'extrémité inférieure de la jupe extérieure 22 est profilée de manière à constituer au moins une surface d'arrêt 30, de préférence deux comme dans l'exemple représenté sur les figures, destinées à coopérer chacune avec une butée d'orientation 15 pour immobiliser le bouchon dans la position angulaire voulue en position de fermeture.The lower end of the outer skirt 22 is profiled so as to constitute at least one stop surface 30, preferably two as in the example shown in the figures, each intended to cooperate with an orientation stop 15 to immobilize the plug in the desired angular position in the position of closing.

Les surfaces d'arrêt 30 sont réalisées dans l'épaisseur de la jupe extérieure 22 et s'étendent parallèlement à l'axe X, comme on peut le voir sur la figure 3.The stop surfaces 30 are made in the thickness of the outer skirt 22 and extend parallel to the X axis, as can be seen in FIG. 3.

Un bossage d'anti-dévissabilité 31, de moindre hauteur que la surface d'arrêt 30, est réalisé à une certaine distance de la surface d'arrêt 30, dans l'épaisseur de la jupe extérieure 22, pour éviter l'auto-dévissabilité du bouchon.An anti-unscrewability boss 31, of lower height than the surface stop 30, is made at a certain distance from the stop surface 30, in the thickness of the outer skirt 22, to avoid self-unscrewing of the plug.

Plus particulièrement, le bossage 31 d'anti-dévissabilité et la surface d'arrêt 30 ménagent entre eux un intervalle 36, de largeur légèrement supérieure à celle de la butée d'orientation 15.More particularly, the anti-unscrewability boss 31 and the surface stop 30 provide between them an interval 36, of width slightly greater than that of the orientation stop 15.

Lors du vissage du bouchon 4 sur le col 3, le bossage d'anti-dévissabilité 31 franchit, par déformation élastique, la butée d'orientation 15 avant que la surface d'arrêt 30 ne vienne en appui sur celle-ci, conférant à l'utilisateur une sensation de point dur, confirmant la bonne fermeture du flacon. When screwing the cap 4 onto the neck 3, the anti-unscrewability boss 31 passes, by elastic deformation, the orientation stop 15 before the surface 30 does not come to rest on it, giving the user a feeling of hard point, confirming the correct closure of the bottle.

Un mouvement en sens inverse du bouchon de lui-même, dû par exemple à la déformation élastique de la capsule intérieure d'étanchéité 5, est empêché grâce à la présence du bossage d'anti-dévissabilité 31.A movement in the opposite direction of the plug itself, due for example elastic deformation of the inner sealing capsule 5, is prevented by the presence of the anti-unscrewability boss 31.

L'utilisateur doit ainsi exercer une force relativement importante pour faire franchir au bossage d'anti-dévissabilité 31 la butée d'orientation 15 lors du dévissage du bouchon.The user must therefore exert a relatively large force to make the anti-unscrewing boss 31 pass the orientation stop 15 during unscrewing the cap.

La bague 12 métallique est rapportée à l'extrémité inférieure de la jupe extérieure 22, laquelle comporte sur sa surface extérieure un épaulement 35 prévu à cet effet.The metal ring 12 is attached to the lower end of the skirt outer 22, which has on its outer surface a shoulder 35 provided at this effect.

La bague 12 est destinée à cacher le profil irrégulier de l'extrémité inférieure de la jupe extérieure 22 lorsque le flacon est fermé, et comporte avantageusement des inscriptions sur sa surface extérieure, tel que par exemple une marque de parfum.The ring 12 is intended to hide the irregular profile of the end lower of the outer skirt 22 when the bottle is closed, and comprises advantageously inscriptions on its external surface, such as for example a perfume brand.

La bague 12 agit également à la manière d'une ceinture pour renforcer la tenue mécanique de l'extrémité inférieure du capot extérieur 6.The ring 12 also acts as a belt to strengthen the mechanical strength of the lower end of the outer cover 6.

Elle est fixée sur ce dernier par tout moyen connu, par exemple par serrage.It is fixed to the latter by any known means, for example by Tightening.

La réalisation des surfaces d'arrêt 30 et des bossages d'anti-dévissabilité 31 dans l'épaisseur de la jupe extérieure 22 du capot extérieur 6 permet de démouler la jupe extérieure 22 par le bas sur la figure 1.The production of stop surfaces 30 and anti-unscrewability bosses 31 in the thickness of the outer skirt 22 of the outer cover 6 makes it possible to demold the outer skirt 22 from below in FIG. 1.

L'ensemble du capot extérieur 6 est avantageusement démoulé par le bas, ce qui permet d'avoir une paroi supérieure 29 sans ouverture ni cache, ce qui peut s'avérer avantageux sur le plan esthétique.The entire outer cover 6 is advantageously removed from the bottom, which allows to have a top wall 29 without opening or cover, which can be aesthetically advantageous.

La ou les surfaces d'arrêt, de même que le ou les bossages d'anti-dévissabilité peuvent être réalisés sur une jupe intérieure du capot extérieur.The stop surface (s), as well as the anti-unscrewability boss (es) can be made on an inner skirt of the outer cover.

A titre d'exemple, on a représenté sur la figure 4 l'extrémité inférieure 21' d'un capot extérieur 6' qui diffère de celui décrit précédemment par le fait que les surfaces d'arrêt 30' et les bossages d'anti-dévissabilité 31' sont réalisés sur la jupe intérieure 23' et non pas sur la jupe extérieure 22'. By way of example, FIG. 4 shows the lower end 21 ' an outer cover 6 ′ which differs from that described above in that the stop surfaces 30 ′ and anti-unscrewing bosses 31 ′ are made on the skirt inner 23 'and not on the outer skirt 22'.

Le positionnement de la ou des butées d'orientation 15 sur le corps 2 de la partie formant réservoir est choisi en fonction de l'emplacement de la ou des surfaces d'arrêt 30 ou 30' sur le capot extérieur.The positioning of the orientation stop (s) 15 on the body 2 of the tank part is chosen according to the location of the 30 or 30 'stop surfaces on the outer cover.

Après le remplissage du corps 2, le bouchon 4 est mis en place de préférence de la façon suivante.After filling the body 2, the plug 4 is put in place preferably as follows.

On commence par visser la capsule intérieure d'étanchéité 5 avec un couple de serrage prédéterminé garantissant une fermeture étanche.We start by screwing the inner sealing capsule 5 with a predetermined tightening torque ensuring tight closure.

Ensuite, le capot extérieur 6 ou 6', pourvu de la bague 12, est descendu verticalement de manière que la jupe intérieure 23 ou 23' s'engage avec friction sur la capsule intérieure 5.Then, the outer cover 6 or 6 ′, provided with the ring 12, is lowered vertically so that the inner skirt 23 or 23 'engages with friction on the inner capsule 5.

L'axe Y peut alors être parallèle aux faces principales 10 du corps 2, chaque surface d'arrêt 30 ou 30' venant se positionner directement au contact d'une butée d'orientation 15.The axis Y can then be parallel to the main faces 10 of the body 2, each stopping surface 30 or 30 'coming to be positioned directly in contact with a orientation stop 15.

En variante, le capot extérieur 6 ou 6' peut être descendu avec l'axe Y formant un angle avec les faces principales 10 du corps 2, et l'on fait ensuite subir au bouchon, après fixation du capot extérieur sur la capsule intérieure, une rotation supplémentaire destinée à amener les surfaces d'arrêt 30 ou 30' en appui sur les butées d'orientation 15.Alternatively, the outer cover 6 or 6 'can be lowered with the Y axis forming an angle with the main faces 10 of the body 2, and then the cap, after fixing the outer cover to the inner capsule, a rotation additional intended to bring the stopping surfaces 30 or 30 'to bear on the orientation stops 15.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits.Of course, the invention is not limited to the exemplary embodiments which have just been described.

On peut notamment modifier la géométrie du corps du flacon et celle du capot extérieur.One can in particular modify the geometry of the body of the bottle and that of the outer cover.
