Abstract

A sachet for insertion into a beverage container prior to the sealing and pressurization of the beverage container. The sachet is made from a gas permeable and substantially liquid impermeable material. The article is positioned within this material and sealed with substantially no excess gas contained therein. The sachet sinks when dropped into the beverage container and subsequently floats after the container is sealed and pressurized as gas from within the container penetrates into the sachet until equilibrium is reached. The sachet then rises within the beverage container when the container is opened.
