[Problem to be Solved by the Invention]
For example, it may be desirable to adjust the amount of cosmetics such as hair styling depending on individual tastes and the weather of the day, and therefore it is desirable to be able to adjust the measurement target value.
[0005]
Even in the above conventional container, the amount of use can be adjusted by stopping the screwing of the discharge member before reaching the upper limit position. However, since the discharge member is substantially rotationally symmetric with respect to its central axis, how many times the member is rotated. It is difficult to count.
[0006]
When a pressure head with a nozzle is screwed into the upper outer surface of the communicating cylinder member instead of the discharge member, the approximate rotation speed of the pressure head can be determined from the position of the nozzle touched by a finger, but there are still inconveniences. For example, a container with a pressure head is usually gripped by placing the container rear wall against a palm when the opening direction of the nozzle hole is the front, but if the direction of the nozzle hole is deviated from the front of the container due to the rotation of the pressure head, The liquid cannot be poured correctly onto the surface. In order to prevent this, the user must visually confirm the position of the nozzle hole after all, which is very troublesome when busy.
