[0032] The specific usage process is as follows: Manually press the liquid outlet head 12 repeatedly. The liquid outlet head 12 moves downward and then upward along the outer ring part 4. The pressing member 5 is compressed and reset. The liquid gradually enters the connector 2 from the container 1, then enters the pressing space 7 from the connector 2, enters the liquid outlet head 12 in the pressing space 7, and finally flows out from the liquid outlet hole 13 of the liquid outlet head 12.

[0033] Reference Figure 5 As shown, a first fastening position 14 is provided at the lower end of the main body part 3, and a second fastening position 15 that cooperates with the first fastening position 14 is provided at the upper end of the container 1.
