2. Description of the Related Art In wide-mouthed bottles such as plum wine bottles, a plastic inner plug having a cavity with a V-shaped cross-section on the lower surface of the peripheral edge and a cylindrical spout on the upper surface is used. Then, in order to prevent the content liquid from flowing out of the spout to the outside of the inner plug when the bottle is turned over, a plug for closing the spout is attached to the upper part of the inner plug. This plug is provided with a connection string for preventing loss. In the past, it was not possible to mold such a plug with a connecting cord integrally with the inner plug, so a plug with a connecting cord was molded separately from the inner plug, and the base of the connecting cord was attached to the protrusion on the top of the inner plug. It was fitted by work. For this reason, a large number of steps are required for molding and mounting thereof, which causes an increase in manufacturing cost.

Incidentally, it is possible to integrally mold the connecting cord 21 having the plug 20 at its tip on the side surface of the plug body 22 of the inner plug by using a molding die as shown in FIG. According to the mold structure of FIG. 6, the cavity string 24 that needs to be vertically pulled out to form the cavity 23 having a V-shaped cross section is used, and the connecting string 21 having the plug 20 at the tip is used.
Can be easily molded.

However, since the connecting cord 21 integrally formed on the side surface of the plug main body 22 of the inside plug is bent and used as shown in FIG. 7, the bent portion 25 becomes an obstacle. Therefore, the plug body 22 cannot be pressed against the bottle mouth portion 27 by the flange 28 of the outer lid 26.
Therefore, such a stopper cannot reliably seal the bottle mouth portion 27 of the wide-mouthed bottle containing a large amount of liquid, and for this reason, it has not been put to practical use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing a state in which the inner plug with a plug of the present invention is incorporated in a wide-mouth bottle, 1 is an inner plug made of soft plastic, 2 is a mouth portion of a wide-mouth bottle with a screw, and 3 is an outer lid. is there. A cavity 5 having a V-shaped cross section is integrally formed on the lower surface of the peripheral portion of the stopper body 4 of the inner stopper 1. The outer periphery of the cavity 5 having a V-shaped cross section is elastically contacted with the inner surface of the mouth portion 2 of the wide-mouth bottle, and the bent portion 6 of the peripheral portion of the stopper body 4 is engaged with the outer surface of the mouth portion 2 of the wide-mouth bottle. The inner stopper 1 is attached to the mouth portion 2 of the wide-bottle bottle by combining them. The outer lid 3 has the inner plug 1 and the mouth portion 2 of the wide-mouth bottle.
Is provided with a flange 10 for pressing against the inner surface of the hollow portion 5 when the outer lid 3 is tightened.
Is pressed by the flange 10 toward the upper surface of the bottle mouth.
As a result, the inner stopper 1 is brought into close contact with the mouth portion 2 of the wide-mouth bottle.

As described above, by using the molding die of the present invention, it is possible to integrally mold the inner plug with the plug of the wide-mouth bottle having the connecting cord having the plug at the tip. This inner plug of the present invention can press the outer lid to seal the mouth of a wide-mouthed bottle such as a plum wine bottle in the same manner as the conventional product in which the plug is separately molded, and after removing the outer lid. The contents can be easily poured out by removing the plug from the spout. Moreover, since it is not necessary to attach a separately formed plug with a connecting cord to the inner plug as in the conventional product, there is an advantage that the manufacturing cost can be reduced.
