Abstract

PROBLEM TO BE SOLVED: To provide a packaging container capable of storing a prescribed volume of a food product such as a beverage and a prescribed volume of carbon dioxide gas, and to provide a method for manufacturing a beverage package capable of manufacturing a food product such as a beverage in which a prescribed amount of carbon dioxide gas is dissolved.SOLUTION: A packaging container comprises an outer container formed of carbon dioxide gas impermeable material and an inner container formed of carbon dioxide gas permeable material, which is arranged inside the outer container, and therefore has a double constitution. The outer container and the inner container are integrated so that the packaging container is provided with a storing part for a food product such as a beverage and a storing part for carbon dioxide gas. With this packaging container, a package of a food product such as a carbonated beverage can be manufactured by filling the beverage into the storing part for a food product such as a beverage, filling carbon dioxide gas into the storing part for carbon dioxide gas, sealing the storing parts and storing the beverage.
【課題】所定容量の飲料等の食品と所定容量の炭酸ガス収納が可能な包装容器を提供し、併せて所定量の炭酸ガスを溶け込ませた飲料等の食品を製造可能な飲料包装体の製造方法を提供する。 【解決手段】炭酸ガス不透過性材料で形成された外容器と、該外容器内に、炭酸ガス透過性材料で形成された内容器を設けて二重構成とし、かつ、外容器と内容器を一体化させて、飲料等の食品収納部と炭酸ガス収納部を具備した包装容器、およびこの包装容器を使用し、前記飲料等の食品収納部に飲料を充填し、前記炭酸ガス収納部に炭酸ガスを充填し、密封保存することにより炭酸ガス入り飲料等の食品包装体が製造できる。 【選択図】図1
