(ES) PROCEDIMIENTO DE FABRICACIÓN DE UN TAPÓN DE PLÁSTICO MOLDEADO CON CAPA FUNCIONAL EMBEBIDA Y TAPÓN DE PLÁSTICO MOLDEADO CON CAPA FUNCIONAL EMBEBIDA
(FR) PROCÉDÉ DE FABRICATION D'UN BOUCHON EN PLASTIQUE MOULÉ À COUCHE FONCTIONNELLE INTÉGRÉE ET BOUCHON EN PLASTIQUE MOULÉ À COUCHE FONCTIONNELLE INTÉGRÉE
Abstract
(EN)
The method comprises the steps of forming a planar element (20) that includes a functional layer (5) and at least one interior layer (1b) of a plastic material connected to said functional layer (5), inserting the planar element (20) into a mould and overmoulding an exterior layer (1a) with another plastic material injected via an injection channel over said planar element (20), in which said exterior and interior layers (1a, 1b) form an end wall (1) of said cap in which said functional layer (5) is encapsulated and located between the exterior and interior layers (1a, 1b). In one embodiment, the planar element (20) includes an intermediate layer (8) connected to one side of the functional layer (5) opposite the interior layer (1b). In another embodiment, the functional layer (5) is encapsulated between the interior and intermediate layers (1b, 8) of the planar element (20).

El procedimiento comprende los pasos de formar un elemento aplanado (20) incluyendo una capa funcional (5) y al menos una capa interior (1 b) de un material plástico unida a dicha capa funcional (5), introducir el elemento aplanado (20) en un molde, y sobremoldear una capa exterior (1a) con otro material plástico inyectado a través de un canal de inyección sobre dicho elemento aplanado (20), donde dichas capas exterior e interior (1a, 1 b) forman una pared final (1) de dicho tapón en la que dicha capa funcional (5) está encapsulada y situada entre las capas exterior e interior (1 a, 1 b). En una realización, el elemento aplanado (20) incluye una capa intermedia (8) unida a un lado de la capa funcional (5) opuesto a la capa interior (1 b). En otra realización la capa funcional (5) está encapsulada entre las capas interior e intermedia (1 b, 8) del elemento aplanado (20).

Selon l'invention, un procédé comprend les étapes consistant à former un élément plat (20) qui comporte une couche fonctionnelle (5) et au moins une couche interne (1b) en matière plastique adhérant à ladite couche fonctionnelle (5), à introduire l'élément plat (20) dans un moule, et à surmouler une couche externe (1a) avec une autre matière plastique injectée à travers un canal d'injection sur l'élément plat (20), lesdites couches externe et interne (1a, 1b) formant une paroi finale (1) dudit bouchon, dans laquelle la couche fonctionnelle (5) est encapsulée et située entre les couches externe et interne (1a, 1b). Dans un mode de réalisation, l'élément plat (20) comprend une couche intermédiaire (8) adhérant à un côté de la couche fonctionnelle (5) opposé à la couche interne (1b). Dans un autre mode de réalisation, la couche fonctionnelle (5) est encapsulée entre les couches interne et intermédiaire (1b, 8) de l'élément plat (20).
