This spout plug has a spout (100) (a spout tool) covered with a cap (200). As a spout with a built-in opening blade, a spout (100) (for example, Japanese Utility Model 5-350) can be used.
There is one disclosed in Japanese Patent Publication No. 58-58. A spout plug containing the opening blade is attached to a spout hole of a liquid paper container sealed with a breakable film, and has a cylindrical portion corresponding to the spout hole. A cylindrical opening blade inserted into the cylindrical portion and having a blade portion on the lower edge, and a cap attached so as to cover the cylindrical portion, the inner surface of the cylindrical portion and the outer surface of the opening blade opposed thereto Are provided with anti-rotation means capable of sliding in contact with each other and moving in the vertical direction, and the opening blade is provided so as to be movable up and down with respect to the cylindrical portion. The cap has a slope inclined toward the lower edge side and facing upward, and the cap has a cylindrical body having a guide slope facing downward and slidingly contacting the slope of the opening blade,
The opening blade is provided so as to be able to descend when the cap is rotated. When the contents are poured out, as shown in FIG. 4, when the cap (200) is rotated and removed, the opening cylinder is rotated by the rotation of the cap. (130) was lowered, the film (30) sealed with the opening blade (132) at the tip was broken, and the container was opened.
