Abstract

An ultra thin ear plug enables sound protection to be conveniently carried inside a wallet. The ear plug is made of a slow-recovery thin foam strip. The user rolls the strip into a cylinder, compresses the cylinder and inserts the compressed foam cylinder into the ear canal. The foam strip can incorporate a pressure sensitive adhesive on one surface so that the ear plug retains the cylindrical shape after being rolled up. Tapered ends can assist sealing by minimizing the existence of an air gap at the center of the cylinder and on the ear canal. A flexible envelope about 0.008 inch thick and of credit card dimensions can provide packaging for two or more ear plugs and can provide a large surface area for promotional advertising. Total thickness of the packaged ear plugs can be thinner than 0.050 inch or the thickness of a credit card.
