PROBLEM TO BE SOLVED: To prevent a mouth part of a tube container from being stained by contents, and to prevent air remaining inside the mouth part from coming in contact with the contents by a method wherein an insert piece to be inserted into a spout on a closing wall formed in the mouth part is provided, dangling from the top of a cap to be screwed down onto the mouth part of the tube container. SOLUTION: A tube container main body 1 is formed of a laminated tube or the like, and an external thread is formed at the outer circumference of its mouth part 2. A closing wall 3, separating the mouth part 2 from a trunk part at the inside, is formed at the inner circumferential face at the base of the mouth part 2, and a spout 5 for discharging contents 4 is bored at the center of the closing wall 3. In a cap 6 to be screwed down onto the external thread on the mouth part 2, an insert piece 7 is formed at the inside of its top so that the tip of the insert piece 7 can be inserted into the spout 5 when the cap 6 is screwed down. Thereby, when the mouth part 2 is closed with the cap 6 screwed down, the insert piece 7 closes the spout 5 completely, and thereby air 8 remaining inside the mouth part 2 is prevented from coming in contact with the contents 4. |
