Claims

1. A synthetic resin container having a bottom, a side wall extending upward from the bottom, and an opening on the upper end of the side wall, A thread-shaped projection is provided on the upper end side of the side wall, outside the opening. The aforementioned thread-shaped projection has an inner wall and an outer wall that are parallel to each other. The width between the inner wall and the outer wall is greater than 0 and 1.5 mm or less. A synthetic resin container characterized in that the inner wall and outer wall are configured to be elastically deformable and able to come into contact with each other.

2. The synthetic resin container according to claim 1, characterized in that the inner or outer wall of the thread-shaped projection is provided with a narrowing portion that partially narrows the width between the inner wall and the outer wall.

3. The synthetic resin container according to claim 2, characterized in that the narrow portion is provided in two or more stages in the vertical direction.

4. A synthetic resin container according to any one of claims 1 to 3, characterized in that a part of the outer casing can be inserted and attached between the inner wall and the outer wall of the thread-shaped protrusion.

5. The lower end of the aforementioned side wall is provided with a projection that protrudes outward. The synthetic resin container according to claim 4, characterized in that the projection is configured to engage with a locking portion provided on the outer casing.

6. The synthetic resin container according to claim 5, characterized in that a part of the upper end of the outer casing is inserted between the inner wall and the outer wall of the thread-shaped projection, and the projection on the lower end of the side wall is engaged with the locking part on the lower end of the outer casing, thereby enabling the outer casing to be sandwiched between the upper and lower ends.

7. A synthetic resin container according to any one of claims 1 to 6, characterized in that it is configured to be able to attach a lid that covers the opening.
