ALUMINUM CONTAINER FOR WINE

WIPO Patent Application WO/2019/151189

A1

The present invention relates to an aluminum container for wine, which is composed of an aluminum can body and an aluminum can lid that covers an opening of the can body. A polyester resin coating is formed on the inner surface of the aluminum can body, said polyester resin coating having a thickness of 4 μm or more in the barrel part of the can body; and a coating film, which has a thickness of 6 μm or more and is formed from a polyester/phenol coating material, is formed on the inner surface of the aluminum can lid. Consequently, corrosion of the container and deterioration of the flavor of wine are effectively prevented without using a special scavenger for trapping sulfurous acid even in cases where the container is filled with wine that contains sulfite, and is hermetically sealed.
