Is formed. The anti-screwing direction means a direction in which the stopper body 10 and the lid body 71 are turned when removed.

  Therefore, when the stopper body 10 is screwed into the container body 2 and the torque required to push down the click piece 103 by the lower edge portion 11F of the grip portion 11 is set as the screwing torque, the locking state is changed to the anti-screwing direction. The anti-screwing torque necessary for rotation becomes larger than the screwing torque, and the plug body 10 can be prevented from being loosened.

Further, as a modification of the second embodiment, the positioning stopper 101 and the stopper piece 102 may not be provided. In this case as well, the reference tightening by the locking of the click piece 103 and the click locking portion 121 is also possible. The plug body 10 can be screwed into the position. In this case, the widths W and W1 may be substantially the same if the click piece 103 is possible for the click locking portion 121.

  As described above, in this embodiment, corresponding to claim 3, when the click piece 103 is temporarily retracted, a larger torque is required when opening the plug body 10 than when closing the plug body 10. Since it is configured, loosening of the plug body 10 can be prevented, while it is easy to tighten.

26, the third embodiment of the present invention will be described in detail with the same reference numerals assigned to the same parts as in the first embodiment, and detailed description thereof omitted. In this example, the gaps between the side surface parts 121A and 121A of the click locking part 121 are formed obliquely so as to expand downward. Further, the click piece 103 of the third embodiment is locked to the click locking portion 121. In the first and second embodiments and the reference example , the side surface portion of the click locking portion 121 is formed substantially vertically.

  Therefore, even if the plug body 10 is rotated in either the screwing direction or the counter-screwing direction, the click piece 103 is pushed downward by the side surfaces 121A and 121A formed obliquely, and the click locking portion 121 and the click piece The lock with 103 can be released.

In addition, this invention is not limited to the above Example, A various deformation | transformation implementation is possible within the range of the summary of invention. For example, in the embodiments, the positioning stopper has a shape that is long in the circumferential direction, but various shapes such as a round protrusion can be used. Similarly, the stopper portion can have various shapes. Moreover, in Example 1 , 2 , the side part of the click latching | locking part is comprised like Example 3 , and the latching | locking part for a click and a click piece are latched by turning a plug main body without using an operation member. You may comprise so that can be cancelled | released. Furthermore, you may form only one side part of the latching | locking part for clicks diagonally.
