In the example shown in FIG. 9, at least a part of the second engaging convex portion 19 faces the first engaging convex portion 18 and the first engaging convex portion in the circumferential direction of the outer cylindrical wall 11. 18 is disposed on one end side. Specifically, the end portion 18b of the first engagement convex portion 18 and the side edge 19b of the second engagement convex portion 19 substantially coincide with each other in the circumferential direction.

  According to this configuration, the cap-side engaging convex portion 27 moves in the rotational direction along the first engaging convex portion 18 by the rotation of the measuring cap 5 attached to the nozzle plug 3 and the set portion. When 25 gets over the second engagement protrusion 19, the cap-side engagement protrusion 27 moves in the rotational direction more than the first engagement protrusion 18. As a result, the upper engagement portion 29 is released substantially simultaneously with the lower engagement portion 30 being released by the rotation of the measuring cap 5. Thereby, the measurement cap 5 can be removed from the container main body 1 (nozzle inner plug 3) with few rotation operations.

  In addition, the positional relationship between the first engaging convex portion 18 and the second engaging convex portion 19 is not limited to the illustrated one. The first engagement convex portion 18 and the second engagement convex portion 19 do not have to be opposed to each other. For example, the second engagement convex portion 18 is further second in the rotation direction of the measuring cap 5 than the first engagement convex portion 18. The engaging convex part 19 may be arranged.

  As described above, the preferred embodiments according to the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the examples. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs to.
