CAP OF BEVERAGE CONTAINER

摘要

The objective of the present invention is to provide a stopper of a beverage container, which is easily poured while maintaining compactness of a product. The stopper comprises: an external stopper (12) which is attached to an upper opening (2) of a container body (1) and has an outlet route (16R) arranged therein; and an internal stopper (13) attached to an upper opening (12J) of the external stopper (12). On the inner circumferential surface of the external stopper (12), female screw units for mounting the internal stopper (13) are consecutively arranged in a diameter direction in a spiral shape. Male screw units (22) are arranged to correspond to the female screw units on the outer circumferential surface of the internal stopper (13). A passage (61) is formed by cutting at least a portion of the male screw units (22) in a vertical direction. Arranged in the upper part of the passage (61) of the internal stopper (13) is an upper surface unit (64J) which is a passage inhibiting wall and is linearly inclined toward the external upper part. The female screw units of the external stopper (12) are consecutively arranged, thereby maintaining, all the time, a stable screw fastening status regardless of locations of the passage (61) of the internal stopper (13) and providing stable pouring properties by the upper surface unit (64J) arranged on the upper part of the passage (61).
