| titleOfInvention | Earplugs |
| abstract | ABSTRACT An earplug composed of a resilient polymeric material and comprising an elongate stalk member having a nose end, and a flange array comprising at least three hollow, rearwardly extending flange elements of substan-tial circular cross sections and of serially increas-ing diameters integrally affixed to the stalk member at spaced intervals along at least a portion of the length thereof, the flange element of the smallest diameter being located at the nose end. Each flange element is of generally hemispherical shape, and comprises a thin skirt having a substantially uniform thickness of between about 0.008 inch (0.20 mm) and about 0.050 inch (1.27 mm). It is composed of a resilient polymeric material of construction having a Shore A Durometer hardness value of between about 10 and about 90. The diameter of each portion of the stalk member underlying each skirt is such as to define an annular free space between the interior surface of said skirt and said stalk member. This earplug is comfortable to wear properly and provides competent acoustic sealing of the ear canals. |
