The present invention relates to a stopper for a packaging container wherein the stopper comprises bridges for checking whether a screw-coupling type stopper is opened or not and a hinge portion where an inner depressed groove is formed, thereby displaying whether the stopper is opened or not and enabling the stable connection of a main body portion of the stopper and a fixing ring, a set opening angle of the main body portion of the stopper is maintained in case of opening, thereby preventing the main body portion of the stopper from drooping and being shaken, and opening and closing operations are elastically carried out, thereby remarkably improving the feeling of use. To implement the above, the present invention comprises: the fixing ring for preventing separation from a main body of a container and preventing idling; the main body portion of the stopper for opening and closing the main body of a container, where a screw portion is formed on an inner circumferential surface; the hinge portion for connecting the fixing ring and the main body portion of the stopper; and a plurality of bridges formed between the main body portion of the stopper and the fixing ring, which are cut if the stopper is opened. A cutting line for extending a connection length to the main body portion of the stopper is formed around the lower portion of the hinge portion in the fixing ring, and the depressed groove, which is formed to the inside of the main body portion of the stopper and the fixing ring by an inner slider undercut portion of an injection molding machine, is formed at the hinge portion in such a way that there is a level difference between the depressed groove, and the main body portion of the stopper and ribs of the fixing ring. |
