Plug assembly for beverage container

摘要

Provided is a plug assembly for a beverage container, exhibiting a favorable pourability without hindering a compactness. The assembly includes: an outer plug (12) fitted into an upper opening of a container body (1) and having an outflow passage (16R) therein; and an inner plug (13) fitted into an upper opening section of the outer plug (12). Provided on the inner circumferential surface of the outer plug (12) is a female screw (21) having a thread continuous in the radial direction and used to attach the inner plug (13). Provided on the outer circumferential surface of the inner plug (13) is a male screw (22) corresponding to the female screw (21). Flow passages (61) are formed by vertically cutting out at least a part of the male screw (22), and provided on the upper regions of the flow passages (61) are control walls (64J) linearly slanting upward and outward. A stable screwed state can be consistently maintained regardless of the locations of the flow passages (61).
