Patent ID: 10349709

Abstract:
User-wearable rings are disclosed that are expandable, antimicrobial, and/or breathable. Each ring is shaped into a toroid formed at least partly of an expandable polymer having an elastic modulus no greater than 5 gigapascals (GPa). The toroid is sized to fit snugly over a digit of a user and is configured to expand as needed. Some ring implementations include antimicrobial elements disposed within the expandable polymer. In some implementations the antimicrobial elements include ionic silver. Some ring implementations include precious materials, such as precious metals or crushed pearl, interspersed within the expandable polymer. Some ring implementations include one or more colorants having a color matching the color of one or more precious materials interspersed in the ring. Some ring implementations include grooves formed on an inner surface of the ring and allowing moisture, dirt, grime, and the like to exit from between the digit of the user and the ring.
