PROBLEM TO BE SOLVED: To prevent the liquid in a container from flowing out (leakage) when the container is tumbled, without bringing a complicated structure and restricting smooth extraction of the liquid on using. SOLUTION: The inner side end 14 in a liquid container 1, of a suction hole 11 is stretched lower than the inner side end 7 of the liquid container 1, of a delivery hole 5. The suction hole 11 and the delivery hole 5 are formed so that the part A of the delivery hole 5 and the part B of the suction hole 11 are under almost the same certain head pressure, lest air passes either delivery hole 5 filled with the liquid E or suction hole 11 and enters into the inside of liquid container 1, when the liquid container 1 is tumbled on a horizontal face S in the state that the liquid E is contained therein. |
