Description

La présente invention concerne l'industrie du conditionnement. Elle vise plus particulièrement des capuchons pouvant servir éventuellement de bouchons, notamment pour des récipients de produits cosmétiques ou de parfumerie où l'aspect, l'esthétique, la qualité au moins apparente, sont importants, de même que le poids qui donne souvent une impression flatteuse de solidité.The present invention relates to the packaging industry. It relates more particularly to caps which may possibly serve as stoppers, in particular for containers of cosmetic or perfumery products where appearance, aesthetics, quality at least apparent, are important, as is the weight which often gives an impression. flattering strength.

L'invention a pour but de permettre la réalisation industrielle de capuchons présentant les qualités requises à un coût avantageux.The invention aims to allow the industrial production of caps having the required qualities at an advantageous cost.

On connaît par le document GB-A-727 529 une capsule ou capuchon composite comprenant un noyau en forme de coupe retournée, en matériau relativement inerte et inesthétique (en l'occurrence, un plastique souple) solidarisé par moulage avec une coiffe, en matériau relativement résistant et esthétique (en l'occurrence un métal). Le noyau en plastique est fileté et destiné à la fixation du capuchon au col d'un récipient.Document GB-A-727,529 discloses a composite capsule or cap comprising a core in the form of an inverted cup, made of relatively inert and unsightly material (in this case, flexible plastic) secured by molding with a cap, of material relatively resistant and aesthetic (in this case a metal). The plastic core is threaded and intended for fixing the cap to the neck of a container.

Cette technique destinée à minimiser le poids de matière plastique utilisée ne répond pas aux objectifs de l'invention, notamment parce qu'elle va à l'encontre de l'augmentation de poids éventuellement souhaitée.This technique intended to minimize the weight of plastic material used does not meet the objectives of the invention, in particular because it goes against the increase in weight that may be desired.

Selon l'invention, la coiffe se continue à l'intérieur de l'évidement axial du noyau par des prolongements intérieurs, éventuellement réunis en un prolongement intérieur unique, qui assurent la fixation du capuchon sur le col, ou autre élément analogue solidaire du récipient.According to the invention, the cap is continued inside the axial recess of the core by internal extensions, possibly combined in a single internal extension, which ensure the fixing of the cap on the neck, or other similar element integral with the container. .

Ces prolongements ou ce prolongement unique peuvent s'étendre sur tout ou partie dudit évidement axial, et même recouvrir tout ou partie du fond intérieur du noyau.These extensions or this single extension can extend over all or part of said axial recess, and even cover all or part of the inner bottom of the core.

Suivant un mode de réalisation particulièrement avantageux, les prolongements de la coiffe sont constitués par ou comprennent des languettes parallèles à l'axe du capuchon dont une partie marginale longitudinale est solidaire du noyau, et la partie marginale contigue, centripète et élastiquement déformable radialement, est appelée à frotter contre le col, ou autre élément analogue solidaire du récipient.According to a particularly advantageous embodiment, the extensions of the cap are constituted by or include tongues parallel to the axis of the cap, a longitudinal marginal part of which is integral with the core, and the contiguous, centripetal and elastically deformable radial part of the cap is called to rub against the neck, or other similar element secured to the container.

Suivant une variante, les prolongements de la coiffe présentent un taraudage appelé à coopérer avec un filetage du col, ou autre élément analogue solidaire du récipient.According to a variant, the extensions of the cap have a tapping called to cooperate with a thread of the neck, or other similar element secured to the container.

La coiffe peut présenter, de préférence, des nervures longitudinales internes assurant le calage en rotation du noyau dans la coiffe, en coopération avec des évidements complémentaires du noyau.The cap may preferably have internal longitudinal ribs ensuring the rotation of the core in the cap, in cooperation with complementary recesses in the core.

L'aspect esthétique est particulièrement assuré lorsque la coiffe forme le sommet, la paroi latérale cylindrique, et le pourtour de l'ouverture du capuchon, les prolongements de la coiffe remontant à l'intérieur de l'évidement cylindrique axial du noyau sur une partie seulement de sa profondeur.The aesthetic aspect is particularly assured when the cap forms the top, the cylindrical side wall, and the periphery of the opening of the cap, the extensions of the cap going up inside the axial cylindrical recess of the core on a part only of its depth.

Il est généralement avantageux que le noyau présente des protubérances radiales internes de calage des extrémités des prolongements de la coiffe.It is generally advantageous for the core to have internal radial protuberances for wedging the ends of the extensions of the cap.

L'invention est particulièrement adaptée à la fabrication par moulage, quand les matériaux de la coiffe et du noyau sont tous deux des matières plastiques.The invention is particularly suitable for manufacturing by molding, when the materials of the cap and of the core are both plastics.

On obtient une excellente cohésion entre la coiffe et le noyau lorsqu'ils sont réalisés dans des matériaux comportant une matière plastique de base de même nature, mais chargés différemment.Excellent cohesion is obtained between the cap and the core when they are made of materials comprising a basic plastic material of the same kind, but loaded differently.

Ainsi, la coiffe peut être avantageusement réalisée en polypropylène normal tandis que le noyau est en polypropylène alourdi par des charges minérales.Thus, the cap can advantageously be made of normal polypropylene while the core is made of polypropylene weighed down by mineral fillers.

Un avantage particulier de l'invention réside dans la possibilité de réaliser de tels capuchons entièrement en matériaux recyclables et/ou biodégradables.A particular advantage of the invention lies in the possibility of producing such caps entirely from recyclable and / or biodegradable materials.

L'invention pourra être plus clairement comprise par l'examen et la description détaillée des dessins annexes qui représentent un mode de réalisation de l'invention et une variante, choisis simplement à titre d'exemples parmi les nombreuses formes d'exécution, adaptations et variantes de l'invention concevables par un technicien averti.The invention can be more clearly understood by examining and describing the detailed drawings which show an embodiment of the invention and a variant, chosen simply by way of examples from the numerous embodiments, adaptations and variants of the invention conceivable by an experienced technician.

Sur ces figures, les éléments correspondants sont désignés par les mêmes références numériques, éventuellement affectées d'un indice. Les dimensions et les proportions respectives de ces éléments peuvent ne pas être respectées pour une meilleure lisibilité des dessins.In these figures, the corresponding elements are designated by the same reference numerals, possibly assigned an index. The dimensions and the respective proportions of these elements may not be respected for better readability of the drawings.

Le capuchon suivant l'invention, représenté sur les figures 1 et 2 est essentiellement composé d'un noyau 1 et d'une coiffe 2. Le noyau, en forme de coupe retournée est solidarisé par moulage de la coiffe qui l'entoure complètement à l'extérieur et se prolonge, dans l'évidement axial 6 du noyau par quatre prolongements 3 parallèles à l'axe du capuchon et également répartis circonférentiellement. Ces prolongements sont constitués chacun par une languette dont une partie marginale longitudinale relativement épaisse formant talon 4, est enfermée dans la paroi interne du noyau, tandis que la partie marginale contigue 5, relativement mince, fait saillie librement hors de la paroi interne du noyau, dans l'évidement axial 6. Les parties marginales 5 sont flexibles et élastiquement déformables radialement, ce qui leur permet d'assurer le maintien, à frottement doux, du capuchon sur un élément cylindrique solidaire du col d'un récipient 7, représenté ici par un fourreau 8 emboîté à frottement dur sur une capsule 9, sertie sur le col du récipient pour y fixer une valve de distribution d'aérosol, ou une petite pompe classique, dont la tubulure axiale 10 est terminée par un poussoir 11 d'actionnement manuel, logé librement dans le fond de l'évidement axial 6 du noyau.The cap according to the invention, shown in FIGS. 1 and 2, is essentially composed of a core 1 and a cap 2. The core, in the form of an inverted cup, is joined by molding the cap which completely surrounds it. the outside and is extended, in the axial recess 6 of the core by four extensions 3 parallel to the axis of the cap and also distributed circumferentially. These extensions each consist of a tongue, a relatively thick longitudinal marginal portion forming heel 4, is enclosed in the inner wall of the core, while the contiguous marginal portion 5, relatively thin, protrudes freely outside the inner wall of the core, in the axial recess 6. The marginal parts 5 are flexible and elastically deformable radially, which allows them to ensure the maintenance, with gentle friction, of the cap on a cylindrical element integral with the neck of a reci pient 7, represented here by a sheath 8 fitted with hard friction on a capsule 9, crimped on the neck of the container to fix there an aerosol dispensing valve, or a small conventional pump, whose axial tubing 10 is terminated by a push-button 11 for manual actuation, housed freely in the bottom of the axial recess 6 of the core.

Des nervures longitudinales 12, espacées, issues de la face interne de la paroi extérieure de la coiffe 2 sont enfermées, lors du moulage, dans la face latérale externe du noyau et solidarisent en rotation le noyau et la coiffe.Longitudinal ribs 12, spaced, coming from the internal face of the external wall of the cap 2 are enclosed, during molding, in the external lateral face of the core and in rotation secure the core and the cap.

Les prolongements 3 ne s'étendent que sur environ la moitié inférieure de la profondeur du capuchon. Leurs extrémités 13 butent sur des protubérances radiales internes du noyau 1 qui les calent axialement lors de l'enfoncement du capuchon à glissement sur le fourreau 8.The extensions 3 extend only over approximately the lower half of the depth of the cap. Their ends 13 abut on internal radial protuberances of the core 1 which wedge them axially when the sliding cap is pressed onto the sheath 8.

Pour réaliser ce capuchon suivant les techniques classiques, on peut commencer par mouler d'abord le noyau 1 avec des rainures correspondant au logement des talons 4 et des nervures 12 de la coiffe. On dispose ensuite le noyau dans un autre moule pour l'injection de la coiffe. L'évidement tronconique axial 14 du sommet du noyau sert au centrage et au maintien du noyau dans le moule d'injection ainsi qu'éventuellement au passage de la buse d'injection pour le moulage de la coiffe.To make this cap according to conventional techniques, one can start by first molding the core 1 with grooves corresponding to the housing of the heels 4 and ribs 12 of the cap. The core is then placed in another mold for the injection of the cap. The axial frustoconical recess 14 of the top of the core is used for centering and holding the core in the injection mold as well as possibly for the passage of the injection nozzle for molding the cap.

On peut aussi commencer par mouler la coiffe avant de l'insérer dans un moule où l'on injectera le noyau.We can also start by molding the cap before inserting it into a mold where we will inject the core.

Dans la variante représentée sur la figure 3, le capuchon est vissé directement sur le col 18 d'un récipient 7a. Il comprend un noyau 1 a enfermé dans une coiffe 2a dont la face interne des prolongements intérieurs 3a présente un taraudage 16 complémentaire du filetage 15 du col du récipient. Une rondelle d'étanchéité 17 est disposée classiquement au fond du capuchon, en appui sur la face inférieure interne du noyau. Suivant les applications, ou pourra réaliser le taraudage, soit dans la totalité de la face externe de plusieurs prolongements séparés et espacés, soit d'un prolongement unique en doigt de gant retourné, dont toute la face opposée est en contact avec la face interne du noyau, comme représenté sur la figure 3.In the variant shown in Figure 3, the cap is screwed directly onto the neck 18 of a container 7a. It comprises a core 1 enclosed in a cap 2a, the internal face of the interior extensions 3a has a thread 16 complementary to the thread 15 of the neck of the container. A sealing washer 17 is conventionally disposed at the bottom of the cap, bearing on the inner underside of the core. Depending on the applications, or may perform tapping, either in the entire external face of several separate and spaced extensions, or of a single extension in a turned-over thermowell, the entire opposite face of which is in contact with the internal face of the core, as shown in Figure 3.

En variante, le taraudage peut être localisé dans les parties marginales flexibles longitudinales 5 des prolongements de la coiffe du capuchon des figures 1 et 2.As a variant, the thread can be located in the longitudinal flexible marginal portions 5 of the extensions of the cap of the cap of FIGS. 1 and 2.

On pourra avantageusement mouler la coiffe de tels capuchons suivant l'invention, en polypropylène classique d'aspect brillant, offrant la possibilité de belles colorations, d'un toucher agréable, et présentant l'élasticité nécessaire pour assurer une liaison agréable et durable entre le capuchon et un récipient. On pourra de même mouler le noyau en polypropylène alourdi jusqu'à une densité voisine de 2 par des charges minérales classiques. Ainsi, on pourra réaliser, à faible coût et à de bonnes cadences industrielles, des capuchons esthétiques et de densité agréable pouvant être entièrement recyclés.It is advantageously possible to mold the cap of such caps according to the invention, in conventional polypropylene with a shiny appearance, offering the possibility of beautiful coloring, of a pleasant touch, and having the elasticity necessary to ensure a pleasant and lasting bond between the cap and container. We can similarly mold the weighted polypropylene core to a density close to 2 by conventional mineral fillers. Thus, it will be possible to produce, at low cost and at good industrial rates, aesthetic caps of pleasant density which can be entirely recycled.
