Patent number: 8671948Abstract: An apparatus and a method of making a corded earplug, including a flexible cord material and a pair of earplugs. Each earplug has a nose portion for insertion into the ear and a rear portion extending from the nose portion and lying outside of the ear when the nose portion is inserted into the ear. Each rear portion has a pair of openings physically displaced from each other and/or angularly displaced from each other. At least one of the openings extends through the rear portion. A short portion of the flexible cord material is inserted through the at least one opening extending through the rear portion. The short portion of the flexible cord material is then inserted into the other opening to have the short portion of the flexible cord material physically displaced and/or angularly displaced along its length to lock the flexible cord material to the rear portion of the earplug.Type: GrantFiled: September 28, 2010Date of Patent: March 18, 2014Assignee: Moldex-Metric, Inc.Inventor: Crest Turdjian

Patent number: 8413663Abstract: A hearing protective earplug for insertion into the human ear canal of a user where the human ear canal has sidewalls and a typical curved portion. A soft resilient body has a main body element with a front end for insertion in the human ear canal. An elongated stem has two ends with one end attached to the main body element. The stem extends outward from the main body element and away from the front end. The other end of the stem forms a handle portion of the stem. The stem is sufficiently stiff as to allow manipulation of the main body element into the ear canal of the user. The stem member has a crooked or wavy configuration within the ear canal as it extends outward from the main body to the handle portion of the stem. As the front end of the main body element is inserted into the ear canal, the stem member is rotated during insertion with the handle portion to fit around the typical curved portion in the human ear canal.Type: GrantFiled: February 4, 2011Date of Patent: April 9, 2013Assignee: Moldex Metric, Inc.Inventors: Crest Turdjian, Mark Magidson
