A monolithic earplug (10) being compressible or deformable. The earplug is fabricated from an extruded, elastomeric thermoplastic in order that it may be rapidly and efficiently produced, and then the extrudate is cut at the die face, as it emerges therefrom, into discrete pieces to form earplugs (10) having convex end portions and a skin extending over its entire outer surface.

L'invention concerne un bouchon d'oreille monolithique (10) compressible ou déformable, qui est fabriqué à partir d'un thermoplastique élastomère assurant une production rapide et efficiente. L'extrudat est ensuite coupé en pièces discrètes, au niveau de la tête d'extrusion, au fur et à mesure qu'il en sort, pour former des bouchons d'oreille (10) présentant des parties d'extrémité convexes et une peau s'étendant sur toute la surface extérieure.
