Thermally conductive cap

Abstract

A cap for a liquid-containing bottle. The cap has a sidewall with inwardly facing threads and a ceiling with a plurality of openings. The ceiling extends between the sidewalls to form a chamber into which a liquid containing bottle is inserted. The composition of the cap includes a plurality of thermally conductive particles having a particle size ranging from about 25 microns to about 70 microns. The cap's composition ranges from about 5% to about 20% by weight of the particles and preferably includes an oxygen-scavenging additive incorporated into the cap to remove oxygen from an airspace above a contained liquid.
