PURPOSE: To arrest water flowing along a body part of a tube container body to a rear side of a discharge port cap by a watertight fitting means when a tube container is in an inverted posture by providing the watertight fitting means between a shoulder part of the tuber container body and an exterior peripheral wall of the discharge port cap.
CONSTITUTION: In an inverted tube container, a discharge port cap 2 is fitted to a mouth-neck part 11 of a tube container body 1, and a cover body 3 is openably/ closeably fitted to the discharge port cap 2. In this case, a watertight fitting means 4 is provided between a shoulder part 12 of the tube container body 1 and an exterior peripheral wall 21 of the discharge port cap 2. Namely, a shoulder cylinder 14 is projected on the shoulder part 12 of the tube container body 1. The exterior peripheral wall 21 of the discharge port cap 2 is fitted over the outer peripheral surface of the shoulder cylinder 14 in a watertight manner. A fitting interior peripheral wall 22 is formed inside the exterior peripheral wall 21 to be fitted in the inner peripheral surface of the shoulder cylinder 14. In this manner, when the tube container is in an inverted posture, water running along a body part 13 of the tube container body 1 to the rear side of the discharge port cap 2 can be arrested by the watertight fitting means 4.
