<p>Provided in the present invention is a stopper of a container for a beverage, where a dividing line on a resin mold is not necessary in a water stop unit. The stopper of a container for a beverage comprises: a resin drinking opening main body (9) which is fastened by inserting a screw into an opening (2) of a container main body (1); and a resin cap (4) which is fastened by inserting a screw into the drinking opening main body (9). Female screws (34) where the cap (4) is inserted are partially placed in the inner side of the drinking opening main body (9), and a cap water stop unit (19) is formed in the lower part of a second female screw (34). During resin molding, the partially placed second female screw (34) is partially molded in a different shape independently from the cap water stop unit (19) so that the cap water stop unit (19) does not have any dividing line due to resin molding. In addition, a cap side attachment unit (31) is molded in a different shape independently from a male screw (35) during resin molding, and a cap side water stop member (30) is attached to the lower part of the cap (4) which does not have any dividing line due to resin molding. Because any dividing line exists in the cap water stop unit (19) of the drinking opening main body (9), water can be surely blocked between the drinking opening main body (9) and the cap (4).</p> |
