Title (EN) EARPLUG ASSEMBLY AND METHOD FOR FORMING THE SAME
(FR) ENSEMBLE DE BOUCHON D’OREILLE ET PROCÉDÉ DE FORMATION DE CELUI-CI
Abstract:
(EN) An earplug assembly includes a first earplug, a second earplug, and a cord including a first end, a second end, each earplug including a stem and a sound attenuating body. A method for preparing the earplug assembly includes attaching the first and second ends of the cord to the first and second earplugs, respectively, by contacting a hot tip to the proximal end of the stem of the earplug to form an attachment point, removing the hot tip, and contacting or inserting the end of the cord to the attachment point to thermally bond the end of the cord to the stem of the earplug.
(FR) La présente invention concerne un ensemble de bouchon d'oreille qui comprend un premier bouchon d'oreille, un second bouchon d'oreille, et un cordon comprenant une première extrémité, une seconde extrémité, chaque bouchon d'oreille comprenant une tige et un corps d'atténuation de son. Un procédé de préparation de l'ensemble de bouchon d'oreille comprend la fixation des première et seconde extrémités du cordon aux premier et second bouchons d'oreille, respectivement, par la mise en contact d'une pointe chaude avec l'extrémité proximale de la tige du bouchon d'oreille pour former un point de fixation, le retrait de la pointe chaude, et la mise en contact ou l'insertion de l'extrémité du cordon dans le point de fixation pour lier thermiquement l'extrémité du cordon à la tige du bouchon d'oreille.
