An improved method to provide cooling properties to common beverage containers or sport water bottles is described. Specifically, a thermal cooling insert is universally applicable for use in many such containers used by outdoors, bicycle and fitness enthusiasts. The thermal insert is comprised of a molded polyethylene hollow tube filled with a safe, non-toxic refrigerant material which imparts cooling benefit to beverages held inside the container for extended periods of time. The refrigerant material is hermetically sealed inside the tube. The insert includes a flexible "spring loading" stabilizing assembly system which allows simple insertion into and removal from the container and effectively holds the insert in place during use. A shock absorbing assembly may be incorporated into the bottom of the insert to help hold the insert in place, cushion the insert and reduce rattling during use. A stem section with tab grips is designed to facilitate insertion and removal and to fit in both large and small containers.
