A spring 74 is installed in the countersunk hole 81, and the length direction of the spring 74 is arranged along the circumferential direction of the inner wall of the countersunk hole 81, and the two ends of the length direction of the spring 74 abut against the boss 75 and the limit ring 73 respectively.

[0042] How to use the soft bottle packaging is as follows:

[0043] ① Such as Figure 1 As shown, in the initial state, the cover 4 presses the outlet 32, and the bottom of the pressure plate 6 abuts against the upper end of the membrane 52 to close the upper end of the crack 521. The second plate 72 is rotated so that the second rod 7 drives the first rod 62 to rotate around the axis of the second rod 7, so that the bottom of the pressure plate 6 leaves the membrane 52.

[0044] When the rod body 7 rotates, the boss 75 compresses the spring 74 .

[0045] ② Squeeze the shell 1 and the inner liner 2 so that the emulsion in the inner liner 2 flows out from the crack 521 and flows into the cavity connected to the cavity 11.

[0046] ③ Release the second plate 72, and the boss 75 is reset under the action of the spring 74, so that the bottom of the pressure plate 6 abuts against the upper end of the membrane 52, and the upper end of the crack 521 is closed. The emulsion in the inner tank 2 is sealed and protected, and its shelf life is increased. The emulsion to be used is stored in the cavity 11, and the user can judge whether to use steps ①② to extract the emulsion from the inner tank 2 by observing the amount of emulsion in the cavity 11.

[0047] ④ Pull out the cover 4, squeeze the shell 1, and squeeze the emulsion out from the outlet 32. When squeezing, the shell 1 can be facing upwards and the cover 4 can be facing downwards to facilitate the discharge of the liquid.

[0048] ⑤ After use, the cover 4 is inserted to close the outlet 32.
