In this case, the overcap 6 removed from the dispensing cap 5 can be used as a measuring cap.

In the above embodiment, the circumferential lengths of the first engaging groove 25 and the first engaging convex portion 26 are equal to each other, and the relative cap circumferential direction of the dispensing cap 5 and the regulating portion 7 is aligned. However, the movement is not limited to this as long as the movement of at least the loose side along the relative cap circumferential direction between the dispensing cap 5 and the container 2 can be regulated by the regulating unit 7. For example, the circumferential length of the first engaging convex portion 26 is made shorter than the circumferential length of the first engaging concave groove 25, and the unidirectional direction along the relative cap circumferential direction of the dispensing cap 5 and the regulating portion 7 is set. Only movement may be regulated.
Moreover, in the said embodiment, the circumference of each of the 2nd engagement ditch | groove 27 and the 2nd engagement convex part 28 is made mutually equivalent, Both along the relative cap circumferential direction of the container 2 and the control part 7 Although the movement in the direction is restricted, the restriction part 7 is not limited to this as long as the movement of at least the loose side along the relative cap circumferential direction between the dispensing cap 5 and the container 2 can be restricted. For example, the peripheral length of the second engaging convex portion 28 is made shorter than the peripheral length of the second engaging concave groove 27, and the container 2 and the restricting portion 7 are only moved in one direction along the relative cap peripheral direction. May be regulated.

  In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
