これらの薄肉脆弱線に発生する危惧が少なくなる。As shown in FIG. 5, for example, the conventional seal plug (30) has a ring-shaped thin fragile wire on the closing plate (430) below the inside of the spout (420) of the spout (400). (431) is formed, and this thin line of weakness (43
1) is a sticking ring (41) that is heat-sealed to the liquid paper container.
It is relatively close to 1). On the other hand, in the seal plug (10) of the present invention, as shown in FIG. 1, the three thin fragile wires (211, 212, 213) are connected to the spout (100).
Is formed above the upper end of the spout barrel (120), and these thin lines of weakness are relatively distant from the liquid paper container and the adhesive ring (111) that is heat-sealed.
Therefore, pinholes due to ultrasonic impact during heat fusion,
There is less concern about these thin lines of weakness.
