PURPOSE: To protect an easy-to-oxide component, particularly a vitamin component, and prevent the oxidation of a fatty acid by converting a bottle with an oxygen-impermeable wall by an outer packing low in permeability to oxygen and arranging an oxygen trap between the outer packing and the bottle. CONSTITUTION: The outside wall of a bottle 1 is formed by an oxygen- impermeable transparent thermoplastic material. The wall of an outer packing 2 covering the bottle 1 consists of at least one layer of a transparent thermoplastic material low in permeability to oxygen and is preferably arranged under vacuum on the outer periphery of the bottle 1. An oxygen trap 3 is arranged between the bottle 1 and the outer packing 2 under vacuum, and formed in a capsule or bag filled with a material capable of capturing oxygen generated in the outer packing. An oxygen indicator 4 to indicate the presence of oxygen is arranged between the bottle 1 and the outer packing 2. |
