The present invention provides a double plastic container cap assembly capable of preventing taste from being spoiled by preventing the oxidation when food solution is stored for long since the assembly prevents air from coming into an inner container formed into a double plastic container when or after pouring food solution into the inner container. The purpose of the invention is achieved by the double plastic container cap assembly including a cap member (110) composed of a lower cap having an air inhaling hole of both sides assembled with an inlet of an outer container to connect to a gap between the inner container penetrating an outlet connected to the inner container, and an upper cap including a sealing protrusion connected to a side of the lower cap by a hinge piece to seal the outlet; a diaphragm valve (210) including a valve body assembled with a combination support protrusion protruding from the bottom surface of the lower cap, an attached elastic piece attached to the air inhaling hole of an outer surface of the valve body, a support plate having multiple leakage holes by protruding from an inner surface of the valve body, and a blocking film in the center of the support plate; and a valve sheet (310) including a sealing sheet assembled with an inner surface of the inlet of the inner container to support the attached elastic piece while being attached to a lower part of the blocking film. |
