发明名称 EARPLUG SHAPER HAVING CURVED SHAPING SURFACES
摘要 An earplug shaping device shapes a compressible earplug prior to insertion of the earplug into a user's ear canal. The device includes a first member and a second member which rotate with respect to each other. The outer surface of the first member and inner surface of the second member define a space that decreases in size as the first and second members rotate with respect to each other, thereby compressing the compressible earplug. Various embodiments of the earplug shaper employ ratchet mechanism permitting substantially only one direction of rotation.
