PROBLEM TO BE SOLVED: To provide a plug body hinge structure of a beverage container in which a lid body is certainly engaged, compactification of a plug body is possible and degree of freedom in an industrial design is high.SOLUTION: A plug body hinge structure of a beverage container includes: a plug body 11 which is fitted to an opening end part of a container body and has a liquid flowing hole inside; and a lid body 12 which is connected as rotatable with the plug body 11 by a hinge shaft 15 and opens and closes the liquid flowing hole. A lid body hinge part 81 of the lid body 12 is connected with a plug body hinge part 82 of the plug body 11 by the hinge shaft 15, a housing part 85 is provided at the lid body hinge part 81. At the housing part 85, a slide member 86 which is slidable in the shaft direction of the hinge shaft 15 and a compression coil spring 87 which energizes the slide member 86 in the shaft direction are provided. Since the slide member 86 is brought into press contact with the plug body hinge part 82 by the compression coil spring 87, the hinge is allowed to have stable elasticity and can be compactified by housing these structures inside the hinge without unitization. |
