PROBLEM TO BE SOLVED: To instantly cut a liquid, and prevent the liquid from dripping by curving an injection pipe of an injection container under a state wherein a straight section is left, and cutting the injection pipe at the highest section of the curve. SOLUTION: By leaving a straight section 3 on an injection pipe 2, a length from the central section 4 of a curve to the base section 6 of the injection pipe is made longer than a length from the central section 4 of the curve to the highest section 5 of the curve. As a result, right after an injection of a liquid, a force by which a residual liquid in the pipe is pulled back into the container from the tip end section, is increased. Also, by cutting the tip end at the highest section 5 of the curve, a reverse flow into the pipe from the tip end section works most strongly under a natural form, and by a multiplier effect with the pulling back force into the container by the straight section 3, a liquid cutting can be instantly performed. In addition, by making the straight section 3 of the injection pipe 2 longer, and the curve at the tip end smaller, the reverse flow dropping force becomes larger, and the injection pipe can be adopted for a highly viscous substance such as oils for industrial use, as well.
