Abstract
Provided is an airtight container for positive pressure beverage that has a cap which is able to improve airtightness. The airtight container for beverage is provided with a beverage container and a cap. The beverage container has a body portion and a flange. The flange is continuous with an upper portion of the body portion and defines an orifice. The cap is attached to the beverage container so as to seal the orifice. The cap has a liner and an exterior body. The liner has a thin liner portion for sealing a lower side portion of the flange and a thick liner portion for sealing an upper side portion of the flange. The exterior body is fixed to the flange so as to cover the liner from an outer side, in order to seal the orifice together with the liner. The exterior body presses the thin liner portion against the lower side portion of the flange and brings the thin liner portion in close contact therewith.
