Description

CAPSULE DISTRIBUTRICE A EMBOUT RETRACTILE, POUR RECIPIENTS. DISPENSING CAPSULE WITH RETRACTILE END CAP, FOR CONTAINERS.
L'invention concerne une capsule distributrice à embout rétrac- tile, pour récipients.The invention relates to a dispensing capsule with retractable tip, for containers.
Les systèmes de bouchage classiques dits "à bec verseur", sont connus, notamment pour les produits d'entretien, les cosmétiques ou certaines boissons.The classic so-called "pouring spout" closure systems are known, in particular for cleaning products, cosmetics or certain drinks.
Généralement, le bec verseur est fixé sur le col ou la bague du récipient, tandis qu'un capuchon vient recouvrir ledit bec par vissage sur le col.Generally, the spout is fixed to the neck or the ring of the container, while a cap covers said spout by screwing onto the neck.
On comprend que pour utiliser un récipient ainsi équipé, il y a lieu bien sûr de retirer au préalable complètement le capuchon.It is understood that to use a container thus equipped, it is of course necessary to remove the cap completely beforehand.
Par ailleurs, on connaît des capsules distributrices, dites encore "capsules service", qui remplacent avantageusement les simples bouchons ou capuchons à dévisser, lesdites capsules restant attenantes au récipient, tandis que l'ouverture et la fermeture s'effectuent par une manoeuvre particulière de la capsule.Furthermore, dispensing capsules are known, also called "service capsules", which advantageously replace the simple plugs or caps to be unscrewed, said capsules remaining adjoining the container, while the opening and closing are carried out by a particular operation of the capsule.
Afin notamment de conserver les avantages à la fois du bec verseur et de la capsule service précitée, ainsi d'ailleurs que pour assurer certaines fonctions d'essuyage du bec, on a déjà imaginé la capsule distributrice décrite dans le brevet Français 2 631 318, du type comportant un capuchon qui est monté fixe en translation axiale par rapport au récipient, mais dont au moins une partie d'actionnement est montée tournante, et qui est pourvu d'au moins une ouverture de passage dans laquelle un embout pourvu d'un orifice de distribution du produit est monté mobile entre au moins une position rétractée d'obtu- ration et une position en saillie d'ouverture, tandis qu'un obturateur prévu pour être fixé sur le col du récipient est muni d'un bouchon destiné à venir obturer ou libérer l'orifice de l'embout lorsque celui-ci est en position respectivement rétractée d'obturation ou en saillie d'ouverture, le mouvement de l'embout étant assuré par des moyens conjugués prévus sur celui-ci, dans le capuchon et sur l'obtura¬ teur.In particular in order to preserve the advantages of both the pouring spout and the aforementioned service capsule, as well as to ensure certain functions of wiping the spout, the dispensing capsule described in French patent 2,631,318 has already been imagined of the type comprising a cap which is mounted fixed in axial translation relative to the container, but at least one actuation part of which is rotatably mounted, and which is provided with at least one passage opening in which a nozzle provided with a product dispensing orifice is mounted movable between at least one retracted closure position and a projecting opening position, while a shutter intended to be fixed on the neck of the container is provided with a cap intended for close or release the orifice of the end piece when the latter is in the respectively retracted shutter position or projecting from the opening, the movement of the end piece being provided by means of combined pre seen thereon, in the cap and on the shutter.
Dans ce dispositif connu, le capuchon et l'embout sont solidai¬ res en rotation et libre en translation, tandis que l'embout se visse et se dévisse sur l'obturateur de telle sorte qu'ainsi l'embout au cours de son mouvement hélicoïdal tourne en même temps que le capu¬ chon.In this known device, the cap and the endpiece are solid in rotation and free in translation, while the endpiece is screwed and unscrewed on the shutter so that the endpiece during its movement helical rotates at the same time as the cap.
On comprend aussi que dans une telle structure, tout le méca- 7/39961 PC17FR97/00664We also understand that in such a structure, all the mechanics 7/39961 PC17FR97 / 00664
nisme est positionné à l'extérieur du col du récipient, ce qui réduit d'autant, pour un encombrement extérieur acceptable, le diamètre d'ouverture dudit col à cause de l'addition des épaisseurs des élé¬ ments et limite donc les cadences de remplissage du récipient. En outre, la hauteur de dépassement de l'embout à l'extérieur du capuchon est limitée par la hauteur de l'obturateur sur lequel se visse l'embout, ce qui rend ce dispositif inadapté à certaines utilisa¬ tions.nism is positioned outside the neck of the container, which reduces all the more, for an acceptable external bulk, the opening diameter of said neck because of the addition of the thicknesses of the elements and therefore limits the rates of filling the container. In addition, the height of the tip protruding outside the cap is limited by the height of the shutter on which the tip is screwed, which makes this device unsuitable for certain uses.
C'est pourquoi la présente invention propose une capsule du type précité mais qui est remarquable en ce que l'embout est monté coulissant mais fixe en rotation dans l'obturateur, tandis que les moyens conjugués de l'embout et du capuchon sont des moyens de vissage et de dévissage aménagés respectivement sur la paroi extérieure dudit embout et dans un collier intérieur de la partie d'actionnement tour- nante du capuchon , de telle sorte que la rotation de celle-ci dans un sens ou dans l'autre, entraîne le vissage ou le dévissage de l'embout dans le collier et donc son coulissement sans tourner dans l'obtura¬ teur, ledit embout pouvant ainsi passer de sa position rétractée d'obturation à sa position en saillie d'ouverture ou réciproquement. De la sorte, le mécanisme étant logé à l'intérieur du col du récipient, ledit col présente par la force des choses nécessairement une grande ouverture, ce qui favorise ainsi le remplissage du réci¬ pient.This is why the present invention provides a capsule of the aforementioned type, but which is remarkable in that the end piece is mounted to slide but fixed in rotation in the shutter, while the combined means of the end piece and the cap are means. screwing and unscrewing respectively arranged on the outer wall of said nozzle and in an inner collar of the rotating actuating part of the cap, so that the rotation thereof in one direction or the other, causes screwing or unscrewing the end piece in the collar and therefore sliding without turning in the obtura¬ tor, said end piece thus being able to pass from its retracted shutter position to its position projecting from the opening or vice versa. In this way, the mechanism being housed inside the neck of the container, said neck necessarily has a large opening, which thus favors the filling of the container.
En outre, le dépassement de l'embout vers l'extérieur peut être important puisque le mécanisme qui entre dans le col du réci¬ pient, voire dans le récipient lui même, présente une hauteur qui peut être supérieure à la hauteur extérieure de la capsule et qui n'est en tous cas pas limitée par ladite hauteur extérieure.In addition, the protrusion of the tip towards the outside can be significant since the mechanism which enters the neck of the container, or even into the container itself, has a height which can be greater than the outside height of the capsule. and which is in any case not limited by said external height.
De préférence, les moyens conjugués de vissage et de dévissage du capuchon et de l'embout sont tels qu'une rotation de la partie d'actionnement tournante dudit capuchon dans le sens trigonométrique ou respectivement rétrograde en regardant celui-ci, entraîne un vissa¬ ge ou respectivement un dévissage de l'embout dans le collier et donc un mouvement d'ouverture ou respectivement de fermeture. Avantageusement, les moyens conjugués du capuchon et de l'em¬ bout comportent un taraudage ou des moyens en saillie aménagés dans le collier et des moyens conjugués aménagés sur la paroi extérieure de l'embout sous forme de moyens en saillie ou respectivement d'un fileta¬ ge.Preferably, the combined means of screwing and unscrewing the cap and the end piece are such that a rotation of the rotating actuating part of said cap in a trigonometric or respectively retrograde direction while looking at it, causes a vissa¬ ge or respectively an unscrewing of the end piece in the collar and therefore an opening or respectively closing movement. Advantageously, the combined means of the cap and of the tip comprise a tapping or protruding means arranged in the collar and combined means arranged on the outer wall of the nozzle in the form of projecting means or respectively of a thread.
Selon un mode de réalisation, le capuchon est d'une seule pièce, montée rotative sur le col du récipient, le collier d'actionne- ment étant réalisé par une cheminée intérieure du capuchon, aménagée coaxialement à l'ouverture dudit capuchon.According to one embodiment, the cap is in one piece, rotatably mounted on the neck of the container, the actuating collar being produced by an internal chimney of the cap, arranged coaxially at the opening of said cap.
Dans ce cas, pour des raisons de fabrication et des problèmes de coût, la cheminée intérieure du capuchon est fendue diamétralement pour un moulage par arrachage. En effet, il est connu qu'un moule à arrachage, par rapport à un moule à dévissage, est bien moins onéreux et permet en outre de plus grandes cadences de fabrication.In this case, for manufacturing reasons and cost problems, the inner chimney of the cap is split diametrically for tear-off molding. Indeed, it is known that a tear-off mold, compared to a unscrewing mold, is much less expensive and also allows higher production rates.
Notamment, mais pas exclusivement, dans ce cas, l'obturateur présente une jupe centrale destinée à venir entourer la cheminée du capuchon sur laquelle elle peut tourner, de telle sorte que la chemi¬ née du capuchon, bien que fendue, reste parfaitement maintenue.In particular, but not exclusively, in this case, the shutter has a central skirt intended to come and surround the chimney of the cap on which it can rotate, so that the chemi¬ born of the cap, although split, remains perfectly maintained.
D'autres particularités peuvent bien sûr être prévues et c'est ainsi, par exemple, que selon un mode de réalisation, la paroi exté¬ rieure de l'embout et la paroi intérieure de la cheminée du capuchon sont pourvues de moyens élastiques qui coopèrent entre eux par accro¬ chage en position rétractée afin de provoquer un signal sonore et/ou un verrouillage à l'ouverture et à la fermeture, par passage en force des moyens l'un sur l'autre, au cours de la translation dudit embout. Toutefois, on peut parfaitement imaginer un mode de réalisa- tion dans lequel le capuchon présente une enveloppe extérieure fixe, la partie tournante étant constituée par un collier commandé par un levier qui fait saillie vers l'extérieur au travers d'une fenêtre ménagée dans ladite enveloppe fixe.Other particularities can of course be provided and this is how, for example, that according to one embodiment, the outer wall of the end piece and the inner wall of the chimney of the cap are provided with elastic means which cooperate between them by hooking in the retracted position in order to cause an audible signal and / or a locking on opening and closing, by force passage of the means one over the other, during the translation of said endpiece . However, one can perfectly imagine an embodiment in which the cap has a fixed outer casing, the rotating part being constituted by a collar controlled by a lever which projects outwardly through a window provided in said fixed envelope.
Les moyens conjugués de coulissement de l'embout et de l'obtu- rateur sont, par exemple, constitués par des rainures ou des nervures aménagées sur l'embout et des nervures ou respectivement des rainures aménagées dans l'obturateur et selon un mode de réalisation, l'embout présente une partie cylindrique tubulaire qui chapote le bouchon de l'obturateur, lequel bouchon se présente sous la forme d'une tige, tandis que les moyens conjugués de coulissement de l'embout et dudit obturateur comportent des ailettes disposées à la partie inférieure de ladite tige formant bouchon et des cannelures conjuguées ménagées sur la paroi interne de ladite partie tubulaire de l'embout.The combined means for sliding the end piece and the shutter are, for example, constituted by grooves or ribs arranged on the end piece and ribs or respectively grooves formed in the shutter and according to a mode of embodiment, the end piece has a tubular cylindrical part which caps the plug of the shutter, which plug is in the form of a rod, while the combined means for sliding the end piece and said shutter comprise fins arranged at the lower part of said plug-forming rod and conjugate grooves formed on the internal wall of said tubular part of the end piece.
Pour notamment assurer une double étanchéité, l'invention propose un mode de réalisation qui est remarquable en ce que l'obtura¬ teur comporte un puits qui s'étend dans le col du récipient et dans lequel coulisse l'embout, ledit puits étant fermé à sa base, mais comportant des fenêtres latérales de passage du produit, tandis que la forme et les dimensions de l'embout sont telles qu'en position rétrac¬ tée de fermeture, la paroi extérieure de la base de l'embout vient obturer lesdites fenêtres de telle sorte que ledit embout et l'obtura- teur assurent une double obturation à la fois de l'ouverture du capu¬ chon et desdites fenêtres de passage de l'obturateur.To in particular ensure double sealing, the invention proposes an embodiment which is remarkable in that the obturator comprises a well which extends in the neck of the container and in which the end piece slides, said well being closed at its base, but comprising lateral windows for the passage of the product, while the shape and dimensions of the end piece are such that in the retracted closing position, the external wall of the base of the end piece obtains the said windows so that said end piece and the shutter ensure a double shutter both of the opening of the capu¬ chon and of said shutter passage windows.
L'invention sera bien comprise et d'autres particularités apparaîtront à la lecture de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels:The invention will be clearly understood and other particularities will appear on reading the description which follows and which refers to the appended drawings in which:
- la figure 1 montre en coupe axiale une capsule selon l'inven¬ tion, avec demi-coupe en position d'ouverture et demi-coupe en position de fermeture,FIG. 1 shows in axial section a capsule according to the invention, with half-cut in the open position and half-cut in the closed position,
- la figure 2 montre en demi-coupe axiale une simple variante de la figure 1 en ce qui concerne la forme du capuchon,FIG. 2 shows in axial half-section a simple variant of FIG. 1 as regards the shape of the cap,
- Les figures 3, A et 5 montrent pour moitié en élévation et moitié en coupe axiale, les trois pièces constitutives de la capsule de la figure 1, à savoir respectivement: le capu¬ chon, l'embout et l'obturateur.- Figures 3, A and 5 show half in elevation and half in axial section, the three component parts of the capsule of Figure 1, namely respectively: the capu¬ chon, the tip and the shutter.
Sur les dessins, on peut voir une capsule service selon l'in¬ vention, destinée à venir équiper un récipient 1 (flacon, tube ou analogue) pourvu d'une bague ou d'un col 2 (figures 1 et 2).In the drawings, one can see a service capsule according to the invention, intended to be fitted to a container 1 (bottle, tube or the like) provided with a ring or a neck 2 (Figures 1 and 2).
La capsule selon l'invention comporte ici trois pièces repré¬ sentées séparément sur les figures 3, 4, 5, respectivement un capuchon 3 (figure 3), un embout 4 (figure 4) et un obturateur 5 (figure 5).The capsule according to the invention here comprises three parts shown separately in Figures 3, 4, 5, respectively a cap 3 (Figure 3), a nozzle 4 (Figure 4) and a shutter 5 (Figure 5).
Les trois pièces assemblées entre elles et maintenues sur le récipient 1 sont représentées sur les figures 1 et 2, la figure 2 étant une simple variante en ce qui concerne la forme du capuchon, lequel est cylindrique sur la figure 1 et référencé 3, tandis qu'il est sphérique sur la figure 2 et référencé 3'.The three parts assembled together and held on the container 1 are shown in Figures 1 and 2, Figure 2 being a simple variant with regard to the shape of the cap, which is cylindrical in Figure 1 and referenced 3, while 'he is spherical in Figure 2 and referenced 3 '.
Pour des raisons de clarté et pour éviter des répétitions inutiles, toutes les références de la figure 1 ne sont pas reprises intégralement sur la figure 2, puisque tous les éléments sont identi- ques à l'exception seulement de la forme du capuchon.For reasons of clarity and to avoid unnecessary repetitions, all the references in FIG. 1 are not repeated in full in FIG. 2, since all the elements are identical except only for the shape of the cap.
L'obturateur 5, montré de manière séparée sur la figure 5, présente une jupe extérieure 6 pourvue de dentures extérieures 7 et d'une nervure d'extrémité 8 de façon à venir se fixer de manière immobile sur le col 2 du récipient 1, comme le montrent les figures 1 et 2, au moyen d'une nervure 9 et de dentures 10 conjuguées aménagées sur ledit col 2 dont le bord de l'ouverture est chevauché par ladite jupe extérieure 6 de l'obturateur 5.The shutter 5, shown separately in FIG. 5, has an outer skirt 6 provided with outer teeth 7 and an end rib 8 so as to be fixed immobile on the neck 2 of the container 1, as shown in FIGS. 1 and 2, by means of a rib 9 and of conjugate teeth 10 arranged on said neck 2, the edge of the opening of which is overlapped by said outer skirt 6 of the shutter 5.
L'obturateur 5 présente en outre un puits central 11 qui s'étend de manière étanche dans l'ouverture du col 2 et dans le réci- pient 1 et qui se prolonge à l'opposé par une jupe cylindrique 12.The shutter 5 also has a central well 11 which extends in leaktight manner in the opening of the neck 2 and in the container 1 and which extends opposite by a cylindrical skirt 12.
Le puits 11 est fermé à sa base mais présente latéralement des fenêtres de passage 13 pour le produit contenu dans le récipient 1, tandis que ledit obturateur présente dans sa partie centrale une tige 14 destinée à former un bouchon, comme il sera expliqué ci-après. Le capuchon 3 est monté sur l'obturateur 5 de manière fixe en translation axiale mais libre en rotation, par exemple ici au moyen d'une nervure 15 qui vient se loger à force sous la tranche d'extrémi¬ té de la jupe 6 dudit obturateur.The well 11 is closed at its base but laterally has passage windows 13 for the product contained in the container 1, while the said obturator has in its central part a rod 14 intended to form a plug, as will be explained below. . The cap 3 is mounted on the shutter 5 in a fixed manner in axial translation but free in rotation, for example here by means of a rib 15 which is forced to be housed under the end edge of the skirt 6 of said shutter.
Le capuchon 3 est pourvu d'une ouverture 16 sur le dessus, destinée à laisser passer l'extrémité cylindrique 17 de l'embout 4, ladite extrémité étant pourvue d'un orifice 18 de distribution du produit.The cap 3 is provided with an opening 16 on the top, intended to allow the cylindrical end 17 of the end piece 4 to pass, said end being provided with an orifice 18 for dispensing the product.
L'embout 4 est tubulaire et présente une base cylindrique 19 de plus grand diamètre que sa partie terminale cylindrique précitée 17 et qui est montée coulissante dans le puits 11 de l'obturateur 5.The endpiece 4 is tubular and has a cylindrical base 19 of larger diameter than its abovementioned cylindrical end portion 17 and which is slidably mounted in the well 11 of the shutter 5.
Pour fixer en rotation l'embout 4 et l'obturateur 5 tout en assurant un guidage en translation, ledit obturateur présente (figures 1 et 5) des nervures ou ailettes 20 disposées sur la partie inférieure de sa tige formant bouchon 14 (par exemple deux ailettes diamétrales) et destinées à coopérer avec des rainures ou cannelures conjuguées 21 prévues à l'intérieur de la base cylindrique 19 dudit embout (figures 1 et 4). Pour permettre l'élévation de l'embout 4 ou sa rétraction, la partie cylindrique 19 de celui-ci comporte des éléments en relief, comme des ergots ou, comme ici, des parties de filetage 22 (figures 1 et 4) destinées à coopérer avec un taraudage 23 ménagé sur la paroi intérieure d'une cheminée 24 disposée dans le capuchon 3, coaxialement à son ouverture 16 (figures 1 et 3).To fix the end piece 4 and the shutter 5 in rotation while guiding in translation, said shutter has (FIGS. 1 and 5) ribs or fins 20 arranged on the lower part of its plug-forming rod 14 (for example two diametral fins) and intended to cooperate with conjugated grooves or grooves 21 provided inside the cylindrical base 19 of said nozzle (Figures 1 and 4). To allow the elevation of the end piece 4 or its retraction, the cylindrical part 19 of the latter comprises elements in relief, such as lugs or, as here, thread portions 22 (Figures 1 and 4) intended to cooperate with a thread 23 formed on the inner wall of a chimney 24 disposed in the cap 3, coaxially with its opening 16 (Figures 1 and 3).
Les dimensions et les formes des éléments sont telles qu'en position de fermeture (parties gauches des figures 1 et 2), l'extrémi¬ té 17 de l'embout 4 se loge dans l'ouverture 16 du capuchon 3 et arrive au niveau du dessus de ce dernier, tandis que l'extrémité amincie de la tige 14 obture l'orifice 18 de l'embout 4, et que la base de la partie cylindrique 19 dudit embout obture les fenêtres 13 du puits 11 de l'obturateur 5.The dimensions and shapes of the elements are such that in the closed position (left parts of FIGS. 1 and 2), the end 17 of the end piece 4 is housed in the opening 16 of the cap 3 and arrives at the level from above the latter, while the thinned end of the rod 14 closes the orifice 18 of the end piece 4, and the base of the cylindrical part 19 of said end piece closes the windows 13 of the well 11 of the shutter 5 .
En outre, dans cette position, deux saillies élastiques 25, 26 aménagées dans la cheminée 24 et respectivement sur l'embout 4 au niveau de l'épaulement formé par la transition entre les parties 17 et 19 de celui-ci (figures 1, 3, 4) sont en prise par accrochage.In addition, in this position, two elastic projections 25, 26 arranged in the chimney 24 and respectively on the end piece 4 at the shoulder formed by the transition between the parts 17 and 19 thereof (Figures 1, 3 , 4) are engaged by hooking.
Au contraire, en position d'ouverture (partie droite de la figure 1), l'extrémité 17 de l'embout 4 fait saillie du capuchon 3 de telle sorte que l'orifice 18 et les fenêtres 13 sont débouchés.On the contrary, in the open position (right part of FIG. 1), the end 17 of the end piece 4 projects from the cap 3 so that the orifice 18 and the windows 13 are opened.
En outre, on peut constater que le capuchon 3 présente des éléments d'appui 27 qui viennent en contact sur l'obturateur 5 et que pour notamment améliorer l'étanchéité, l'extrémité de la tige 14 est tronconique, l'ouverture 16 du capuchon 3 est bordée d'une petite jupe 28 intérieure, de même que la base du puits 11 est pourvue d'une couronne 29 qui se loge à la fermeture dans la partie 19 de l'embout 4.In addition, it can be seen that the cap 3 has support elements 27 which come into contact with the shutter 5 and that, in particular to improve the seal, the end of the rod 14 is frustoconical, the opening 16 of the cap 3 is bordered by a small internal skirt 28, just as the base of well 11 is provided with a crown 29 which is housed when closed in part 19 of end piece 4.
Pour assembler les éléments de la capsule entre eux, il suffit de visser d'abord l'embout dans la cheminée 24 du capuchon 3, puis de fixer par clipsage l'obturateur et le capuchon.To assemble the elements of the capsule together, it suffices first to screw the end-piece into the chimney 24 of the cap 3, then to fix by clipping the shutter and the cap.
Il suffit ensuite de disposer la capsule sur le récipient 1 après le remplissage de celui-ci, en fixant l'obturateur sur le col dudit récipient, comme précisé ci-avant. Le fonctionnement est clair. En position d'obturation représentée, comme déjà dit, dans la partie gauche des figures 1 et 2, on comprend que l'orifice 18 est obturé par la tige 14 et que les fenêtres 13 sont obturées par la partie 19 de l'embout 4, assurant ainsi une double étanchéité.Then simply place the capsule on the container 1 after filling thereof, by fixing the shutter on the neck of said container, as specified above. The operation is clear. In the closed position shown, as already said, in the left part of Figures 1 and 2, it is understood that the orifice 18 is closed by the rod 14 and that the windows 13 are closed by the part 19 of the nozzle 4, thus ensuring a double seal.
Pour ouvrir la capsule, il suffit de tourner le capuchon 3, ce qui provoque l'élévation de l'embout 4 par vissage de celui-ci dans la cheminée 24. Toutefois, on comprend que l'embout 4 coulisse sans tourner dans l'obturateur 5 par coulissement des ailettes 20 de l'obtu¬ rateur relativement aux cannelures 21 de l'embout, jusqu'à prendre la position d'ouverture représentée sur la partie droite de la figure 1, position limitée par l'épaulement de transition entre les parties 17 et 19 de l'embout 4 avec la jupe 28 du capuchon. Dans cette position, le produit du récipient 1 peut ainsi passer par les fenêtres 13 de l'obturateur 5 pour parvenir jusqu'à l'orifice 18 en passant autour de la tige 14.To open the capsule, it suffices to turn the cap 3, which causes the end piece 4 to be raised by screwing it into the chimney 24. However, it is understood that the end piece 4 slides without turning in the shutter 5 by sliding the fins 20 of the obturator relative to the grooves 21 of the endpiece, until taking the open position shown on the right part of Figure 1, position limited by the transition shoulder between the parts 17 and 19 of the end piece 4 with the skirt 28 of the cap. In this position, the product of the container 1 can thus pass through the windows 13 of the shutter 5 to reach the orifice 18 by passing around the rod 14.
En tournant dans l'autre sens, on comprend que l'on obtient un mouvement inverse et un passage de la position d'ouverture vers la position d'obturation.By turning in the other direction, we understand that we obtain a reverse movement and a transition from the open position to the closed position.
Pour des raisons d'ergonomie, on choisit un pas pour les moyens de vissage tel qu'une rotation dans le sens trigonometrique ou rétrograde du capuchon 3, en regardant celui-ci, entraîne le vissage ou le dévissage de l'embout et donc l'ouverture ou la fermeture de la capsule.For ergonomic reasons, a pitch is chosen for the screwing means such as a rotation in the trigonometric or retrograde direction of the cap 3, looking at the latter, causes the screw to be screwed or unscrewed and therefore the opening or closing of the capsule.
Enfin, on comprend aussi qu'en début de rotation pour l'ouver¬ ture ou en fin de rotation à la fermeture, les moyens élastiques 25, 26 par passage en force assurent un signal sonore et/ou un verrouilla¬ ge à l'ouverture et à la fermeture, ces moyens étant astucieux car ils auraient pu être prévus plus classiquement sur les éléments tournants. De nombreuses variantes sont évidemment envisageables sans sortir du cadre de l'invention.Finally, it is also understood that at the start of rotation for the opening or at the end of rotation at closure, the elastic means 25, 26 by force passage provide an audible signal and / or a lock on the opening and closing, these means being clever because they could have been provided more conventionally on the rotating elements. Many variants are obviously possible without departing from the scope of the invention.
C'est ainsi notamment que les moyens de vissage 22, 23 de l'embout 4 et de la cheminée 24 peuvent évidemment être inversés (filetage femelle sur l'embout et ergots ou filetage mâle dans la cheminée).Thus, in particular, the screwing means 22, 23 of the end piece 4 and of the chimney 24 can obviously be reversed (female thread on the end piece and lugs or male thread in the chimney).
De même, pour les moyens de guidage en translation de l'embout 4 et de l'obturateur 5, les ailettes 20 et les cannelures 21 peuvent bien entendu être au contraire prévues respectivement dans l'embout et dans l'obturateur.Likewise, for the means for guiding in translation of the end piece 4 and of the shutter 5, the fins 20 and the grooves 21 can of course, on the contrary, be provided respectively in the end piece and in the shutter.
En outre, comme déjà dit, le capuchon 3 pourrait être en deux parties, à savoir une enveloppe fixe et un collier tournant en prise avec l'embout et actionné de l'extérieur par un levier traversant une fenêtre de ladite enveloppe fixe. In addition, as already said, the cap 3 could be in two parts, namely a fixed casing and a collar rotating in engagement with the end piece and actuated from the outside by a lever passing through a window of said fixed casing.
