Description

L'invention concerne un dispositif de fermeture de récipients, notamment de flacons ou de bouteilles, et plus particulièrement une tête de pose de capsules capable de saisir des capsules et de les appliquer sur des flacons pour les fermer.The invention relates to a device for closing containers, in particular vials or bottles, and more particularly a capsule dispensing head capable of grasping capsules and applying them to bottles to close them.

Une ligne d'embouteillage comprend, de façon classique, un convoyeur permettant de transférer des flacons le long de la ligne vers des machines d'embouteillage réalisant différentes opérations nécessaires pour obtenir un produit fini, comme par exemple, un flacon rempli et bouché et sur lequel ont été apposées des étiquettes.A bottling line conventionally comprises a conveyor for transferring bottles along the line to bottling machines carrying out various operations necessary to obtain a finished product, for example, a filled and capped bottle and on which labels have been affixed.

Une ligne d'embouteillage comprend notamment au moins une machine ou un dispositif de bouchage pour fermer un flacon une fois qu'il a été rempli. Le bouchage peut être réalisé à l'aide de capsules qui peuvent être vissées ou enfoncées sur le flacon.A bottling line includes at least one machine or a closure device for closing a bottle once it has been filled. Clogging can be done using capsules that can be screwed or squeezed onto the bottle.

Sur les figures 1 à 3 est illustrée une tête de vissage ou d'enfonçage de capsules connue d'un dispositif de fermeture. La figure 1 présente une vue en perspective de la tête.On the Figures 1 to 3 is shown a head screwing or sinking capsules known to a closure device. The figure 1 presents a perspective view of the head.

La tête 1 illustrée comprend un moyeu 2 couplé à un axe non représenté. Dans le cas d'une tête de vissage, l'axe est un arbre de transmission entraîné en rotation. Dans le cas d'une tête d'enfonçage, l'axe est couplé à un système de translation verticale.The illustrated head 1 comprises a hub 2 coupled to an axis not shown. In the case of a screwing head, the axis is a transmission shaft rotated. In the case of a sinking head, the axis is coupled to a vertical translation system.

Le moyeu 2 est solidaire d'un cône de réception 3 d'un bouchon tel qu'une capsule.The hub 2 is secured to a receiving cone 3 of a plug such as a capsule.

La figure 2 représente une vue en coupe de la tête 1 connue, la coupe étant réalisée selon un plan II-II' comprenant la section d'une capsule C circulaire maintenue par le cône de réception 3. La figure 3 représente une vue en coupe transversale de la tête connue, la coupe transversale étant réalisée selon un plan III-III' comprenant l'axe de rotation du moyeu 2.The figure 2 represents a sectional view of the known head 1, the section being taken along a plane II-II 'comprising the section of a circular capsule C held by the receiving cone 3. figure 3 represents a cross-sectional view of the known head, the cross-section being taken along a plane III-III 'comprising the axis of rotation of the hub 2.

Le cône 3 de réception comprend une gorge 4 circonférentielle apte à recevoir un joint élastique 5. A l'intérieur de la gorge sont prévus cinq orifices 6 traversant le fond la gorge 4 et conformés pour recevoir chacun la tige 71 d'un pion 7 de maintien, également appelé touche.The receiving cone 3 comprises a circumferential groove 4 capable of receiving an elastic seal 5. Inside the groove there are five orifices 6 passing through the bottom of the groove 4 and shaped to each receive the rod 71 of a holding pin 7, also called key.

Chaque pion 7 de maintien comprend une tête 72 circulaire de diamètre supérieur au diamètre de la tige 71 de manière à former une buté. Le pion 7 est conformé de sorte que la tige 71 puisse traverser l'orifice 6 et que la tête 72 vienne en buté contre la portion de la gorge 4 autour de l'orifice 6.Each holding pin 7 comprises a circular head 72 of greater diameter than the diameter of the rod 71 so as to form a stop. The pin 7 is shaped so that the rod 71 can pass through the orifice 6 and that the head 72 comes into abutment against the portion of the groove 4 around the orifice 6.

Les pions 7 sont disposés dans la gorge 4 de manière à ce que la tige 71 de chacun des pions 7 soit insérée dans un orifice 6. Puis le joint élastique 5 est monté dans la gorge 4 en appui contre les têtes 72 des pions 7.The pins 7 are arranged in the groove 4 so that the rod 71 of each of the pins 7 is inserted into a hole 6. Then the elastic seal 5 is mounted in the groove 4 bearing against the heads 72 of the pins 7.

Les extrémités libres des tiges 71 des pions 7 dépassent de l'orifice 6 à l'intérieur du cône de réception 3 de sorte qu'elles soient en appui contre la surface périphérique d'une capsule C lorsqu'une capsule C est insérée dans le cône de réception 3.The free ends of the rods 71 of the pins 7 protrude from the orifice 6 inside the receiving cone 3 so that they bear against the peripheral surface of a capsule C when a capsule C is inserted into the receiving cone 3.

L'espace interstitiel entre la tige 71 de chaque pion 7 et l'orifice 6 dans lequel elle est insérée ainsi que l'espace entre le joint élastique 5 et la gorge 4 forment des zones de rétention. Ces zones de rétention sont susceptibles de recevoir et de conserver des substances liquides, et, par conséquent, de permettre la prolifération de bactéries. L'apparition de substances liquides dans ces zones de rétention peuvent être dues à des projections accidentelles des liquides contenus dans les flacons devant être fermés ou bien au liquide de nettoyage injecté dans le cône de réception 3 lors des phases de nettoyage des machines.The interstitial space between the rod 71 of each pin 7 and the orifice 6 into which it is inserted as well as the space between the elastic seal 5 and the groove 4 form retention zones. These retention zones are capable of receiving and preserving liquid substances, and therefore allow the proliferation of bacteria. The appearance of liquid substances in these retention zones may be due to accidental projections of the liquids contained in the bottles to be closed or to the cleaning liquid injected into the receiving cone 3 during the cleaning phases of the machines.

Lors du nettoyage d'une tête 1 de pose de fermetures, le liquide de nettoyage est injecté dans la tête 1 par le dessous du cône 3 vers l'intérieur du cône de réception 3 et/ou par des ouvertures 8 prévues dans une portion supérieure du cône 3.When cleaning a closure installation head 1, the cleaning liquid is injected into the head 1 from below the cone 3 towards the inside of the receiving cone 3 and / or through openings 8 provided in an upper portion. cone 3.

Ainsi lors du nettoyage d'une tête 1 de pose de fermetures selon l'une des figures 1 à 3, l'aseptisation de la tête ne peut être réalisée qu'en effectuant un démontage du joint 5 et des pions 7, ou touches, de manière à s'assurer de l'évacuation de tout résidu liquide.Thus during the cleaning of a closure installation head 1 according to one of the Figures 1 to 3 , sanitizing the head can be achieved by performing a disassembly of the seal 5 and pins 7, or keys, so as to ensure the evacuation of any liquid residue.

Une tête de pose de fermetures de flacon selon le préambule de la revendication 1 est divulguée dans la demande de brevet WO 2014/057049 A1 . L'invention a pour but de fournir une tête de pose de fermetures de flacon comportant un cône de vissage ou d'enfonçage dont le nettoyage et l'aseptisation peuvent entièrement être réalisés sans aucun démontage de parties de la tête afin de faciliter et de minimiser le temps pour le nettoyage des têtes de pose de fermetures.A bottle closure head according to the preamble of claim 1 is disclosed in the patent application. WO 2014/057049 A1 . The object of the invention is to provide a vial closure dispensing head comprising a screwing or sinking cone, the cleaning and sanitization of which can be carried out entirely without any dismantling of parts of the head in order to facilitate and minimize the time for cleaning the fastening heads.

Selon un aspect de l'invention, il est proposé une tête de pose de fermetures de flacon comprenant un cône de réception d'une fermeture de flacon doté d'un orifice de réception de la fermeture, et des moyens élastiques de maintien de la fermeture.According to one aspect of the invention, there is provided a bottle closure dispensing head comprising a receiving cone of a bottle closure having a closure receiving orifice, and elastic means for holding the closure. .

Selon une caractéristique générale de l'invention, les moyens élastiques comprennent au moins une lamelle élastique comportant une première extrémité fixée au cône de réception et une seconde extrémité libre agencée pour être en contact avec la paroi périphérique de la fermeture insérée dans l'orifice de réception du cône de réception, la lamelle étant configurée pour que la seconde extrémité applique sur paroi périphérique de la fermeture une force apte à assurer le maintien de la fermeture dans le cône de réception et tout en permettant l'insertion de la fermeture dans le cône de réception et le retrait de la fermeture une fois la fermeture appliquée sur le flacon.According to a general characteristic of the invention, the elastic means comprise at least one resilient blade having a first end fixed to the receiving cone and a second free end arranged to be in contact with the peripheral wall of the closure inserted in the orifice of reception of the receiving cone, the slat being configured so that the second end applies on the peripheral wall of the closure a force capable of ensuring the maintenance of the closure in the receiving cone and while allowing the insertion of the closure into the cone; receiving and removing the closure once the closure applied to the bottle.

Le cône de réception de la tête de pose de fermetures réalisée selon l'invention est ainsi dépourvu de zones de rétention. Le (ou les) lamelle(s) élastique(s) permet(tent) de fournir au moins une touche de maintien sans créer de zones interstitielles susceptibles de retenir un liquide.The receiving cone of the closure installation head made according to the invention is thus devoid of retention zones. The elastic slat (s) allows (s) to provide at least one holding key without creating interstitial zones capable of retaining a liquid.

Le cône de réception peut être un cône de vissage ou d'enfonçage de fermetures.The receiving cone may be a cone for screwing or sinking closures.

De préférence, la lamelle élastique est une lamelle métallique dont l'épaisseur et la longueur fournissent l'élasticité nécessaire.Preferably, the elastic lamella is a metal lamella whose thickness and length provide the necessary elasticity.

La réalisation de la lamelle en un matériau métallique permet de fournir une touche de maintien de la fermeture à la fois résistante, légère et élastique.The realization of the lamella in a metallic material makes it possible to provide a key for maintaining the closure that is both strong, light and elastic.

La seconde extrémité de la lamelle élastique peut avantageusement comprendre une portion en saillie vers l'intérieur du cône de réception, la portion en saillie étant conformée pour dépasser à l'intérieur de l'orifice de réception selon une direction radiale, c'est-à-dire selon une direction orthogonale à l'axe de révolution de la tête.The second end of the elastic strip may advantageously comprise a portion projecting inwardly of the receiving cone, the projecting portion being shaped to protrude inside the receiving orifice in a radial direction, that is to say in a direction orthogonal to the axis of revolution of the head.

La portion en saillie forme un bossage interne réduisant localement le diamètre de l'orifice de réception du cône de réception.The protruding portion forms an internal boss locally reducing the diameter of the receiving aperture of the receiving cone.

La portion en saillie peut également être conformée pour s'insérer au moins partiellement dans une gorge de la paroi périphérique de la fermeture.The protruding portion may also be shaped to fit at least partially in a groove of the peripheral wall of the closure.

La portion en saillie peut en outre posséder une forme apte à coopérer avec une rainure verticale de la paroi périphérique d'une fermeture telle qu'une capsule de manière à s'insérer au moins partiellement dans une rainure de la fermeture.The protruding portion may further have a shape adapted to cooperate with a vertical groove of the peripheral wall of a closure such as a capsule so as to be inserted at least partially in a groove of the closure.

La portion en saillie permet ainsi d'orienter la capsule de sorte que les nervures s'étendent en saillie sur la portion périphérique interne du cône en regard des rainures de la paroi périphérique externe de la capsule.The protruding portion thus makes it possible to orient the capsule so that the ribs protrude over the inner peripheral portion of the cone facing the grooves of the outer peripheral wall of the capsule.

De préférence, le cône de réception comprend une encoche par lamelle élastique réalisée dans une portion inférieure du cône de réception selon une direction parallèle à l'axe de révolution de la tête, la lamelle élastique étant disposée de sorte qu'au moins l'extrémité libre s'étende dans l'encoche.Preferably, the receiving cone comprises a notch for each elastic lamella formed in a lower portion of the receiving cone in a direction parallel to the axis of revolution of the head, the elastic lamella being arranged so that at least the end free extends into the notch.

Chaque encoche possède une largeur supérieure à la largeur de la lamelle, et de préférence plus grande d'au moins 4 mm par rapport à la largeur de la lamelle. La tête peut ainsi être entièrement nettoyée sans avoir besoin de démonter les moyens élastiques de maintien de la fermeture.Each notch has a width greater than the width of the lamella, and preferably greater than at least 4 mm with respect to the width of the lamella. The head can thus be completely cleaned without the need to disassemble the elastic means for holding the closure.

La fermeture est préférentiellement une capsule. La capsule peut être une capsule à vis auquel cas la tête de pose de fermetures de flacon est montée sur un arbre rotatif d'un dispositif de fermeture de flacon. La capsule peut également être une capsule à enfoncer sur le buvant d'un goulot de bouteille. Dans ce cas, la tête n'a pas besoin d'être montée sur un arbre rotatif.The closure is preferably a capsule. The capsule may be a screw cap in which case the vial closure head is mounted on a rotating shaft of a vial closure device. The capsule can also be a capsule to be pressed on the rim of a bottle neck. In this case, the head does not need to be mounted on a rotating shaft.

Selon un autre aspect de l'invention, il est proposé un dispositif de fermeture de flacon comprenant au moins une tête de fermeture de flacon tel que défini ci-dessus.According to another aspect of the invention, there is provided a bottle closure device comprising at least one bottle closure head as defined above.

La tête 10 comprend en outre sur une partie inférieure un cône de réception 12 d'une fermeture de flacon tel qu'un bouchon à vis pour une bouteille ou une capsule à enfoncer sur le buvant d'un goulot d'une bouteille. Sur la figure 4 a été représenté un bouchon à vis B comme fermeture.The head 10 further comprises on a lower part a receiving cone 12 of a bottle closure such as a screw cap for a bottle or a capsule to be pressed on the rim of a neck of a bottle. On the figure 4 has been shown a screw cap B as closure.

Dans le mode de réalisation illustré sur la figure 4, la tête 10 est réalisée de sorte que le moyeu 11 et le cône de réception 12 soient en une seule pièce. Cela permet d'éviter de créer des zones de rétention lors de l'assemblage du moyeu et du cône de réception.In the embodiment illustrated on the figure 4 , the head 10 is made so that the hub 11 and the receiving cone 12 are in one piece. This avoids creating retention zones when assembling the hub and the receiving cone.

La tête 10 possède une forme de révolution. Le moyeu 11 possède une forme générale de cylindre creux avec des orifices 13 prévues sur la section d'extrémité supérieure 14 pour fixer la tête 10 à l'arbre. Dans une variante le moyeu peut avoir une autre forme polygonale.The head 10 has a form of revolution. The hub 11 has a generally hollow cylinder shape with orifices 13 provided on the upper end section 14 to secure the head 10 to the shaft. In one variant, the hub may have another polygonal shape.

Le moyeu 11 comprend en outre quatre ouvertures 15 permettant l'injection d'un liquide de nettoyage depuis une partie supérieure de la tête 10. Les ouvertures 15 permettent également de réduire la quantité de matière utilisée pour réaliser la tête 10 et ainsi de réduire le poids de la tête 10. La taille des ouvertures 15 en forme de quadrilatère est maximisée pour qu'un maximum de produit de nettoyage délivré par un injecteur de liquide de nettoyage pénètre dans le moyeu 11 de la tête 10.The hub 11 further comprises four openings 15 allowing the injection of a cleaning liquid from an upper part of the head 10. The openings 15 also make it possible to reduce the amount of material used to make the head 10 and thus to reduce the weight of the head 10. The size of the quadrilateral-shaped openings 15 is maximized so that a maximum of cleaning product delivered by a cleaning liquid injector enters the hub 11 of the head 10.

Le cône de réception 12 de la tête 10 possède également une forme générale de cylindre creux dont l'axe de révolution R est confondu avec celui du moyeu 11. Le cône 12 comprend une partie supérieure 16 solidaire du moyeu 11 et une partie inférieure 17 libre.The receiving cone 12 of the head 10 also has a generally hollow cylinder whose axis of revolution R coincides with that of the hub 11. The cone 12 comprises an upper portion 16 secured to the hub 11 and a lower portion 17 free .

La partie inférieure 17 est configurée pour recevoir le bouchon à vis B. Comme cela est illustré sur la figure 7 qui représente une vue en coupe selon le plan VII-VII' de la tête 10 de la figure 4, le diamètre de l'orifice inférieur 18 destiné à recevoir le bouchon B est strictement supérieur à celui du bouchon B, et la profondeur de l'orifice inférieur 18 est inférieure à la hauteur du bouchon B.The lower portion 17 is configured to receive the screw cap B. As shown in FIG. figure 7 which represents a sectional view along the plane VII-VII 'of the head 10 of the figure 4 , the diameter of the lower orifice 18 for receiving the plug B is strictly greater than that of the plug B, and the depth of the lower orifice 18 is less than the height of the plug B.

La partie supérieure 16 du cône de réception 12 forme à la jonction avec la partie inférieure un épaulement contre lequel la surface supérieur d'un bouchon B inséré dans l'orifice inférieur 18 du cône de réception 12 vient en appui.The upper part 16 of the receiving cone 12 forms at the junction with the lower part a shoulder against which the upper surface of a plug B inserted in the lower orifice 18 of the receiving cone 12 bears.

Comme cela est illustré sur la figure 4, le cône de réception 12 comprend sur sa surface de révolution extérieure, quatre surfaces d'appui 19 planes réparties tout autour du cône de réception 12. Les surfaces d'appui 19 sont planes de manière à permettre l'application d'une force uniforme de serrage par la tête 21 d'une vis 20. La vis 20 de serrage est destinée à maintenir une lamelle 22 en position contre la surface extérieure du cône de réception 12.As illustrated on the figure 4 , the receiving cone 12 comprises on its surface of external revolution, four planar bearing surfaces 19 distributed all around the receiving cone 12. The bearing surfaces 19 are planar so as to allow the application of a uniform force tightening by the head 21 of a screw 20. The screw 20 The clamping device is intended to hold a sipe 22 in position against the outer surface of the receiving cone 12.

Chaque lamelle 22 est réalisée en un matériau métallique avec une épaisseur relativement faible, la finesse de la lamelle 22 lui procurant un caractère élastique, c'est-à-dire une certaine souplesse. Une première extrémité 23 de chaque lamelle 22 est maintenue entre la tête 21 d'une vis de serrage 20 et une surface d'appui 19, et une seconde extrémité 24 libre s'étend verticalement sous la première extrémité 23 le long de la partie inférieure 17 du cône de réception 12.Each strip 22 is made of a metal material with a relatively small thickness, the fineness of the strip 22 providing it with an elastic character, that is to say a certain flexibility. A first end 23 of each blade 22 is held between the head 21 of a clamping screw 20 and a bearing surface 19, and a second free end 24 extends vertically under the first end 23 along the lower part. 17 of the receiving cone 12.

La figure 5 présente une vue éclatée de la tête 10 de la figure 4. Comme cela est illustré sur les figures 4 et 5, la partie inférieure 17 du cône de réception 12 comprend quatre encoches 25 verticales s'étendant depuis l'extrémité inférieure du cône de réception 12 et remontant selon une direction parallèle à l'axe de révolution R du cône de réception 12. Chaque encoche 25 est réalisée dans une partie d'une surface d'appui 19.The figure 5 presents an exploded view of the head 10 of the figure 4 . As illustrated on the figures 4 and 5 , the lower portion 17 of the receiving cone 12 comprises four vertical notches 25 extending from the lower end of the receiving cone 12 and rising in a direction parallel to the axis of revolution R of the receiving cone 12. Each notch 25 is made in a part of a bearing surface 19.

Comme cela est illustré sur la figure 5, la partie supérieure 16 du cône de réception 12 comprend un trou taraudé 26 dans chaque surface d'appui 19, le trou taraudé 26 étant aligné avec l'encoche 25 correspondante selon une direction parallèle à l'axe de révolution R du cône de réception 12. Le trou taraudé 26 permet de recevoir la tige filetée 27 de la vis 20 de serrage associée.As illustrated on the figure 5 , the upper part 16 of the receiving cone 12 comprises a tapped hole 26 in each bearing surface 19, the tapped hole 26 being aligned with the corresponding notch 25 in a direction parallel to the axis of revolution R of the receiving cone 12. The threaded hole 26 makes it possible to receive the threaded rod 27 of the associated clamping screw 20.

Chaque lamelle 22 est fixée sur une surface d'appui 19 du cône de réception 12 à l'aide de la vis de serrage 20. Un premier joint 28 est intercalé entre la tête 21 de la vis de serrage 20 et la première extrémité 23 de la lamelle 22 pour assurer une bonne répartition de la force de serrage sur la lamelle 22 et une étanchéité entre ces deux éléments, et un second joint 29 est intercalé entre la première extrémité 23 de la lamelle 22 et la surface d'appui 19 pour assurer l'étanchéité entre ces deux éléments.Each strip 22 is fixed on a bearing surface 19 of the receiving cone 12 by means of the clamping screw 20. A first seal 28 is interposed between the head 21 of the clamping screw 20 and the first end 23 of the blade 22 to ensure a good distribution of the clamping force on the blade 22 and a seal between these two elements, and a second seal 29 is interposed between the first end 23 of the strip 22 and the bearing surface 19 to ensure the seal between these two elements.

L'ensemble de fixation comportant la vis de serrage 20, la lamelle 22, le premier et le second joints 28 et 29 et la surface d'appui 19 est ainsi imperméable à tout liquide et ne forme aucune zone de rétention.The fastening assembly comprising the clamping screw 20, the strip 22, the first and second seals 28 and 29 and the bearing surface 19 is thus impermeable to any liquid and forms no retention zone.

La figure 6 présente une vue en coupe selon le plan de section VI-VI' de la tête 10 de la figure 4. Comme cela est illustré sur les figures 6 et 7, la seconde extrémité 24 de la lamelle 22 comprend un bossage 30 en saillie vers l'intérieur du cône de réception 12, c'est-à-dire en direction de l'axe de révolution R du cône de réception 12.The figure 6 has a sectional view along the section plane VI-VI 'of the head 10 of the figure 4 . As illustrated on the Figures 6 and 7 , the second end 24 of the lamella 22 comprises a boss 30 projecting towards the inside of the receiving cone 12, that is to say in the direction of the axis of revolution R of the receiving cone 12.

Le bossage 30 de chaque lamelle 22 possède une épaisseur dont la dimension est supérieure à la dimension résultant de la somme de l'épaisseur du second joint 28 avec l'épaisseur de la paroi du cône de réception 12 dans laquelle les encoches 25 sont réalisées. Les bossages 30 dépassent ainsi à l'intérieur de l'orifice inférieur 18 de réception de manière à être en contact avec un bouchon B inséré dans l'orifice inférieur 18 du cône de réception 12.The boss 30 of each lamella 22 has a thickness whose dimension is greater than the dimension resulting from the sum of the thickness of the second seal 28 with the thickness of the wall of the receiving cone 12 in which the notches 25 are made. The bosses 30 thus protrude inside the lower receiving orifice 18 so as to be in contact with a plug B inserted into the lower orifice 18 of the receiving cone 12.

Lorsqu'un bouchon B est inséré dans l'orifice inférieur 18 de la tête 10, il déplace les secondes extrémités 24 des lamelles 22 de leur position de repos, vers l'extérieur. Chaque lamelle 22 exerce alors via le bossage 30 une force de maintien sur le bouchon B et plus particulièrement sur la paroi périphérique ou circonférentielle du bouchon B.When a plug B is inserted into the lower orifice 18 of the head 10, it moves the second ends 24 of the slats 22 from their rest position, to the outside. Each strip 22 then exerts via the boss 30 a holding force on the plug B and more particularly on the peripheral or circumferential wall of the plug B.

Chaque encoche 25 possède une largeur supérieure à deux fois la largeur de la lamelle 22. La largeur d'un encoche 25 est mesurée dans une direction orthogonale au plan comprenant l'axe de révolution R du cône de réception et l'axe de révolution du trou taraudé 26 associé à l'encoche 25, c'est-à-dire aligné avec l'encoche 25. La différence de largeur entre la lamelle 22 et l'encoche 25 permet d'éviter la formation d'une zone de rétention entre la lamelle 22 et les bords de l'encoche 25.Each notch 25 has a width greater than twice the width of the strip 22. The width of a notch 25 is measured in a direction orthogonal to the plane comprising the axis of revolution R of the receiving cone and the axis of revolution of the tapped hole 26 associated with the notch 25, that is to say aligned with the notch 25. The difference in width between the strip 22 and the notch 25 avoids the formation of a retention zone between the blade 22 and the edges of the notch 25.

La tête de pose de fermetures de flacon selon l'invention permet de réaliser un nettoyage et une aseptisation de la tête sans aucun démontage et ainsi de faciliter et de minimiser le temps pour le nettoyage des têtes de pose de fermetures.The bottle closure installation head according to the invention makes it possible to clean and sanitize the head without any disassembly and thus to facilitate and minimize the time for cleaning the closure installation heads.

Plusieurs têtes 10 de pose de bouchons B peuvent être montées sur un dispositif de fermeture de bouteille.Several heads 10 of plugs B can be mounted on a bottle closure device.
