Abstract

L'invention décrit des bouchons pour fermer des bouteilles contenant du liquide ou du gaz. On obtient les bouchons par extrusion, en forme de joncs, d'un mélange d'une polyoléfine, d'un agent de moussage et d'une résine ionomère (copolymère d'éthylène et d'acide méthacrylique). Cette mousse centrale est revêtue d'une matière imperméable à l'humidité et dont le coefficient de frottement est supérieur à celui de la mousse. Convenablement colorés, ces bouchons peuvent servir fermer des bouteilles de vin, que l'on peut déboucher à l'aide d'un tire-bouchon comme pour du liège ordinaire.
