Description

La présente invention concerne un dispositif d'obturation d'un flacon à col du type comprenantd'une part,un adaptateur de col présentant une jupe extérieure de fixation au col du flacon et un manchon interne de bouchage et, d'autre part, un bouchon destiné à s'insérer dans le manchon de bouchage de l'adaptateur de col.The present invention relates to a device for closing a bottle with a neck of the type comprising on the one hand, a neck adapter having an external skirt for fixing to the neck of the bottle and an internal closure sleeve and, on the other hand, a cap intended to be inserted in the closure sleeve of the neck adapter.

On connaît par le certificat d'utilité n° 2 259 761 au nom de la demanderesse un tel dispositif qui s'est avéré particulièrement utile en ce qu'il permet d'assurer un bouchage rapide de toutes sortes de flacons malgré les variations de dimension des goulots des récipients. Dans ce dispositif, l'adaptateur de col est une pièce monobloc en matière plastique et l'étanchéité entre le flacon et l'adaptateur est obtenue par le passage à force d'un jonc sous le profil du col du flacon.We know from utility certificate No. 2 259 761 in the name of the applicant such a device which has proved to be particularly useful in that it makes it possible to ensure rapid closure of all kinds of bottles despite the variations in size. container necks. In this device, the neck adapter is a one-piece plastic part and the seal between the bottle and the adapter is obtained by the forced passage of a rod under the profile of the neck of the bottle.

De ce fait, l'adaptateur doit supporter des contraintes importantes, et notamment des tensions qui sont accentuées par le contact des produits et vapeurs contenus dans le flacon, pouvant amener des fissurations ou un stress-cracking (fissuration sous tension) de la matière.As a result, the adapter must withstand significant stresses, and in particular tensions which are accentuated by the contact of the products and vapors contained in the bottle, which can cause cracking or stress-cracking (stress cracking) of the material.

Le but de l'invention est de proposer un dispositif d'obturation parfaitement sur, dans lequel l'adaptateur de col np risque pas d'être mis hors d'usage.The object of the invention is to provide a perfectly secure closure device, in which the neck adapter np is not likely to be put out of use.

Selon l'invention, ce but est atteint du fait que l'adaptateur de col est constitué de deux pièces distinctes, à savoir un plateau porte-manchon constitué par le manchon de bouchage entouré à sa partie supérieure d'une bride périphérique externe destinée à prendre appui de façon étanche sur le bord supérieur du col du flacon, et une coiffe formée par la jupe extérieure de fixation au col du flacon et comportant un rebord périphérique interne venant coiffer par-dessus au moins une partie de la bride externe du plateau porte-manchon, les deux pièces étant rendues solidaires de façon à permettre la manipulation de l'adaptateur en un seul ensemble, tout en dissociant l'adaptateur de col au regard des contraintes internes susceptibles de s'y développer.According to the invention, this object is achieved by the fact that the neck adapter consists of two separate parts, namely a sleeve-carrying plate constituted by the closure sleeve surrounded at its upper part by an external peripheral flange intended to press tightly on the upper edge of the neck of the bottle, and a cap formed by the outer skirt for fixing to the neck of the bottle and having an internal peripheral rim which covers over at least part of the external flange of the carrier plate sleeve, the two parts being made integral so as to allow manipulation of the adapter in a single assembly, while dissociating the neck adapter with regard to internal stresses likely to develop there.

Ainsi, selon l'invention, l'adaptateur de col peut se présenter extérieurement sous son aspect traditionnel et être en apparence monobloc : il se prête à toutes les opérations classiques de manutention de la même façon que l'adaptateur de col traditionnel, notamment aux opérations de pose automatique sur les flacons.Thus, according to the invention, the neck adapter can appear externally in its traditional appearance and be apparently one-piece: it lends itself to all conventional handling operations in the same way as the traditional neck adapter, in particular to automatic dispensing operations on the bottles.

Toutefois, on a dissocié selon une structure originale les parties de l'adaptateur devant supporter les contraintes de tension et celles risquant d'être en contact avec les produits contenus dans le flacon. Cette dissociation autorise l'emploi de matières différentes pour la réalisation de chacune des deux pièces, en optimisant ainsi les caractéristiques particulières mécaniques ou chimiques préférées pour chacune des deux pièces : notamment la résistance aux agressions chimiques et la souplesse favorisant l'étanchéité pour le plateau porte-manchon, la résistance aux tensions pour la coiffe. Ainsi, se trouvent assurées la durée de vie, la fiabilité et une étanchéité permanente de l'adaptateur de col..However, we have dissociated according to an original structure the parts of the adapter that must withstand the stresses of tension and those likely to be in contact with the products contained in the bottle. This dissociation allows the use of different materials for the production of each of the two parts, thus optimizing the particular mechanical or chemical characteristics preferred for each of the two parts: in particular the resistance to chemical attack and the flexibility promoting sealing for the tray. sleeve holder, tensile strength for the cap. This ensures the service life, reliability and permanent tightness of the neck adapter.

Par ailleurs, la constitution de l'adaptateur de col selon l'invention facilite la fabrication par moulage.Furthermore, the constitution of the neck adapter according to the invention facilitates manufacturing by molding.

Avantageusement, la surface supérieure de la bride du plateau porte-manchon présente un épaulement périphérique ménageant un logement périphérique d'insertion rigoureuse du rebord interne de la coiffe, moyennant quoi le plateau et la coiffe peuvent être assemblés à force et rendus ainsi solidaires.Advantageously, the upper surface of the flange of the sleeve-bearing plate has a peripheral shoulder providing a peripheral housing for rigorous insertion of the internal rim of the cap, whereby the plate and the cap can be forcibly assembled and thus made integral.

Différentes formes d'exécution peuvent être prévues pour assurer la solidarisation mécanique des deux pièces. C'est ainsi qu'elles peuvent être rendues solidaires grâce à un encliquetage du rebord interne dans un épaulement complémentaire de la bride du plateau porte-manchon, ou bien, grâce à une lèvre de sertissage prévue sur la bride du plateau et venant sertir le rebord interne de la coiffe, ou bien encore, grâce à un encliquetage de la bride du plateau dans un creux prévu à la naissance de la jupe de la coiffe, ou bien enfin; grâce à des profils d'embottement portés sur les faces en regard du rebord interne de la coiffe et de la bride,Different embodiments can be provided to ensure the mechanical joining of the two parts. This is how they can be made integral by means of a snap-fastening of the internal rim in a complementary shoulder of the flange of the sleeve-carrying plate, or else, thanks to a crimping lip provided on the flange of the plate and which crimp internal rim of the cap, or else, by snapping the flange of the plate into a recess provided at the birth of the skirt of the cap, or finally; thanks to the embedding profiles carried on the facing faces of the internal rim of the cap and the flange,

Avantageusement, on peut procéder à la solidarisation par surmoulage du plateau porte-manchon dans la coiffe, en prévoyant des organes ou reliefs de retenue adéquats.Advantageously, it is possible to secure it by overmolding the sleeve-holder plate in the cap, by providing adequate retaining members or reliefs.

La figure 1 montre la première pièce, selon l'invention, de l'adaptateur de col, le plateau porte-manchon 1, comportant un manchon tronconique inverse 2 entouré à sa partie supérieure d'une bride périphérique externe généralement circulaire 3. Dans cette bride 3, un épaulement 4 est formé de manière à réserver un logement périphérique 5, généralement circulaire, d'insertion rigoureuse de la coiffe 6 de là figure 2.FIG. 1 shows the first part, according to the invention, of the neck adapter, the sleeve-holder plate 1, comprising a reverse frustoconical sleeve 2 surrounded at its upper part by a generally circular external peripheral flange 3. In this flange 3, a shoulder 4 is formed so as to reserve a peripheral housing 5, generally circular, of rigorous insertion of the cap 6 from there FIG. 2.

Par insertion rigoureuse, il s'entend que le diamètre de l'épaulement 4 et celui de l'orifice 9 sont calibrés de manière à s'ajuster mécaniquement l'un dans l'autre (avec une tolérance de 1/10 mm par exemple) par un assemblage à force que facilitent des chanfreins prévus sur les bords de l'orifice 9 et de l'épaulement 4.By rigorous insertion, it is understood that the diameter of the shoulder 4 and that of the orifice 9 are calibrated so as to adjust mechanically one inside the other (with a tolerance of 1/10 mm for example ) by force assembly facilitated by chamfers provided on the edges of the orifice 9 and the shoulder 4.

Celle-ci est formée d'une jupe extérieure 7, généralement cylindrique, et dotée d'un rebord périphérique interne 8, sous forme de couronne, dont les dimensions permettent son ajustement au logement 5 du plateau porte-manchon 1, avec effet de centrage de l'orifice central 9 autour de l'épaulement 4.This is formed of an outer skirt 7, generally cylindrical, and provided with an internal peripheral rim 8, under crown shape, the dimensions of which allow it to be adjusted to the housing 5 of the sleeve-carrying plate 1, with the effect of centering the central orifice 9 around the shoulder 4.

La figure 3 montre le montage du plateau porte-manchon 1 et de la coiffe 6 sur le col 10 d'un flacon.Figure 3 shows the mounting of the sleeve holder plate 1 and the cap 6 on the neck 10 of a bottle.

La bride annulaire 3 du plateau 1 vient s'appuyer de façon étanche sur un méplat 11 (ou autre profil permettant l'étanchéité) formé sur le bord supérieur du col 10, tandis que le manchon de bouchage 2 est introduit avec jeu dans le col.The annular flange 3 of the plate 1 comes to bear in leaktight fashion on a flat 11 (or other profile allowing sealing) formed on the upper edge of the neck 10, while the closure sleeve 2 is inserted with play in the neck .

La coiffe de fixation 6 vient, par-dessus, se loger par son rebord interne 8 dans le logement 5 et est centrée, d'une part,par la coopération du rebord interne 8 et de l'épaulement 4 es d'autre part, par la coopération de la périphérie de la bride 3 avec la surface interne de la jupe cylindrique 7 de la coiffe 6.The fixing cap 6 comes, above, to be housed by its internal rim 8 in the housing 5 and is centered, on the one hand, by the cooperation of the internal rim 8 and the shoulder 4 es on the other hand, by the cooperation of the periphery of the flange 3 with the internal surface of the cylindrical skirt 7 of the cover 6.

Pour sa fixation au col, la coiffe est munie, à la surface intérieure de sa jupe 7, d'un jonc continu ou interrompu 12, de profil et dimensions déterminés par ceux du renflement annulaire 13 du col 10.For its attachment to the neck, the cap is provided, on the inner surface of its skirt 7, with a continuous or interrupted rod 12, of profile and dimensions determined by those of the annular bulge 13 of the neck 10.

Un jeu 14 est prévu à la base de la jupe 7, du côté intérieur pour faciliter son centrage et sa pose sur le col des récipients.A clearance 14 is provided at the base of the skirt 7, on the inner side to facilitate its centering and its installation on the neck of the containers.

Ainsi, selon l'invention, seule la coiffe 6 subit des contraintes de tension relativement importantes dues à sa fixation par enfoncement à force sur le col du flacon,mais la coiffe 6 est hors de contact avec les produits et vapeurs nocifs du flacon et peut supporter ses contraintes de tension sans difficulté. Elle peut être réalisée dans un matériau rigide résistant bien aux tensions.Thus, according to the invention, only the cap 6 undergoes relatively high tension stresses due to its fixing by forced pressing on the neck of the bottle, but the cap 6 is out of contact with the harmful products and vapors of the bottle and can bear stress constraints without difficulty. It can be made of a rigid material resistant to tensions.

Le plateau porte-manchon ne subit aucune tension : les tensions éventuellement reportées par la coiffe sur le plateau, au niveau de la solidarisation, se transforment, si même elles existent, en une compression radiale de la partie centrale du plateau porte-manchon, cette compression étant sans influence sur la durée de vie ou l'étanchéité dudit plateau. Les caractéristiques du matériau de réalisation du plateau sont essentiellement déterminées par la souplesse et la résistance nécessaires à l'obtention d'une bonne étanchéité entre la bride 3 et le col 10 du flacon,d'une part, entre le manchon et le bouchon,d'autre part. Une étanchéité supplémentaire peut être prévue en donnant au rebord interne 8 de la coiffe une hauteur plus faible que celle de l'épaulement 4, de sorte que celui-ci forme un bourrelet d'étanchéité venant en contact avec le disque supérieur 15 du bouchon 16 (figure 4). Le plateau porte-manchon peut être réalisé par exemple en polyéthylène, en copolymère, en butadiène, etc.The sleeve-carrying plate is not subjected to any tension: the tensions possibly transferred by the cap on the plate, at the level of the connection, transform, if they even exist, into a radial compression of the central part of the sleeve-carrying plate, this compression being without influence on the service life or the tightness of said plate. The characteristics of the material for making the plate are essentially determined by the flexibility and resistance necessary to obtain a good seal between the flange 3 and the neck 10 of the bottle, on the one hand, between the sleeve and the stopper, on the other hand. Additional sealing can be provided by giving the inner rim 8 of the cap a lower height than that of the shoulder 4, so that the latter forms a sealing bead coming into contact with the upper disc 15 of the plug 16 (figure 4). The sleeve support plate can be made, for example, of polyethylene, copolymer, butadiene, etc.

Le bouchon 16 comporte, en dehors de l'organe de bouchage 17 proprement dit, coopérant avec le manchon 2, un disque supérieur 15 couvrant la surface de l'adaptateur de col et muni de deux ou plusieurs ailettes latérales 18 en forme de secteurs cylindriques et comportant une saillie de retenue 19 coopérant avec le bord inférieur 20 de la jupe de la coiffe 6 pour réaliser une retenue amovible. La forme des ailettes 18 contribue au centrage du bouchon sur l'adaptateur de col 1,6 .The plug 16 comprises, apart from the plugging member 17 proper, cooperating with the sleeve 2, an upper disc 15 covering the surface of the neck adapter and provided with two or more lateral fins 18 in the form of cylindrical sectors and comprising a retaining projection 19 cooperating with the lower edge 20 of the skirt of the cover 6 to produce a removable retainer. The shape of the fins 18 contributes to centering the stopper on the neck adapter 1.6.

Le bouchon 16 peut faire partie intégrante d'un capot décoratif associé au flacon, ou constituer une pièce technique rapportée dans ce dernier.The stopper 16 can be an integral part of a decorative cover associated with the bottle, or constitute a technical piece added in the latter.

Naturellement, des variantes de la réalisation ci-dessus peuvent être conçues sans sortir de l'esprit de l'invention.Naturally, variants of the above embodiment can be designed without departing from the spirit of the invention.

C'est ainsi que le plateau porte-manchon 1 peut comporter des dispositifs pour augmenter son étanehéité, tels des joncs; prolongement cylindrique du cône, double paroi, etc., on peut augmenter son inviolabilité par obturation de l'orifice traversant le manchon. On peut aussi y prévoir des reliefs pour le centrage et la fixation du capot.Thus the sleeve-holder plate 1 can include devices to increase its etanehéité, such as rods; cylindrical extension of the cone, double wall, etc., its inviolability can be increased by closing the orifice passing through the sleeve. It can also provide reliefs for centering and fixing the cover.

La coiffe peut également comporter d'autres joncs d'étanchéité, ou bien des dispositifs pour le repérage ou la fixation : méplats, cannelures.The cap may also include other sealing rods, or else devices for locating or fixing: flats, grooves.

La coiffe peut constituer,en outre, une partie décorative par ses coloris, ses formes, ou par des traitements ultérieurs tels que métallisation, impression, marquage, etc.The cap may also constitute a decorative part by its colors, its shapes, or by subsequent treatments such as metallization, printing, marking, etc.

Pour ce qui est de la solidarisation entre le plateau porte-manchon et la coiffe, d'autres modes d'exécution sont représentés sur les figures 5 à 9.With regard to the connection between the sleeve-carrying plate and the cap, other embodiments are shown in FIGS. 5 to 9.

Sur la figure 5, la coiffe et le plateau peuvent s'encliqueter du fait que le rebord 8 a un bord 9a en dépouille pouvant s'emboîter dans un épaulement 4a en contre-dépouille inversée, prévu sur la bride 3 du plateau.In FIG. 5, the cap and the plate can snap into place because the rim 8 has an undercut edge 9a which can fit into a shoulder 4a in reverse undercut, provided on the flange 3 of the plate.

Sur la figure 6, la hauteur de l'épaulement 4 est prévue supérieure à l'épaisseur du rebord 8, et on procède à un sertissage du rebord en formant une lèvre 21 par chauffage direct ou par ondes ultra-sonores.In FIG. 6, the height of the shoulder 4 is provided greater than the thickness of the rim 8, and the rim is crimped by forming a lip 21 by direct heating or by ultrasonic waves.

Sur la figure 7, on a prévu sur les surfaces de contact du rebord 8 et de la bride 3 des dispositifs d'accrochage mâles 22 et femelles 23.In FIG. 7, male 22 and female 23 hooking devices are provided on the contact surfaces of the flange 8 and of the flange 3.

Sur la figure 8, le diamètre de la bride 3 du plateau porte-manchon est prévu supérieur au diamètre intérieur de la coiffe et vient s'introduire dans un logement 24 situé à la naissance de la jupe 7 de la coiffe. En raison de sa souplesse, l'encliquetage du plateau porte-manchon ne pose pas de problème.In FIG. 8, the diameter of the flange 3 of the sleeve-carrying plate is provided greater than the inside diameter of the cap and is introduced into a housing 24 located at the birth of the skirt 7 of the cap. Because of its flexibility, the snap-fastening of the sleeve-holder plate poses no problem.

Sur la figure 8, on a représenté une solution mixte selon laquelle la bride 3 est logée très exactement dans le logement 24 de la coiffe, tandis que le rebord 8 de la coiffe est lui-même inséré dans un logement du plateau formé par l'épaulement 4b et la lèvre supérieure 25. L'intérêt de cette réalisation est qu'on peut la produire par surmoulage direct du plateau 1 sur la coiffe 6.FIG. 8 shows a mixed solution according to which the flange 3 is housed very exactly in the housing 24 of the cap, while the flange 8 of the cap is itself inserted in a housing of the plate formed by the shoulder 4b and the upper lip 25. The advantage of this embodiment is that it can be produced by direct molding of the plate 1 on the cover 6.

Les matériaux préférés pour réaliser la coiffe 6 sont le polypropylène, les polyamides, les polyesters, les polycarbona- tes, l'ABS, l'acétate de cellulose, les polyéthylènes basse densitéThe preferred materials for making the cap 6 are polypropylene, polyamides, polyesters, polycarbonates, ABS, cellulose acetate, low density polyethylenes
