[0029] The liquid outlet nozzle 5 can be arranged on the elastic airbag 3 or on the bottle cap 2.

[0030] This product has two liquid discharge methods. One is to press the elastic airbag, and the air is discharged from the liquid discharge nozzle to form a negative pressure to draw out the liquid in the soft bag. The other is to press the elastic airbag, and the air enters the bottle to squeeze out the liquid in the soft bag.

[0031] Embodiment 1: The air-replenishing structure 4 includes an upper air-replenishing structure 41 located on the top surface of the elastic airbag 3, and a lower air-replenishing structure 42 located at the bottom of the elastic airbag 3, wherein the lower air-replenishing structure 42 is connected to the air barrier between the soft bag 6 and the bottle body 1; the liquid outlet pipe 7 is integrally formed with the liquid outlet nozzle 5, and the lower end of the liquid outlet pipe 7 passes through the bottom of the elastic airbag 3, and the liquid outlet nozzle 5 is pressed, so that the air in the elastic airbag 3 enters the air barrier between the soft bag 6 and the bottle body 1 through the lower air-replenishing structure 42, and squeezes the soft bag 6, so that the liquid at the upper end of the soft bag 6 is discharged from the liquid outlet nozzle 5 through the liquid outlet pipe 7, and the liquid outlet nozzle 5 is released, the elastic airbag 3 is restored, and negative pressure is formed in the elastic airbag 3, and the external air is replenished into the elastic airbag 3 through the upper air-replenishing structure 41. Figure 2 shown.

[0032] Embodiment 2: The difference from Embodiment 1 is that the lower liquid outlet pipe 72 is integrally formed with the elastic airbag 3, the lower end of the upper liquid outlet pipe 71 passes through the bottom of the elastic airbag 3, and is inserted into the upper end of the lower liquid outlet pipe 72. The liquid outlet nozzle 5 is pressed, and the air in the elastic airbag 3 enters the air barrier between the soft bag 6 and the bottle body 1 through the lower air replenishing structure 42, squeezing the soft bag 6, so that the liquid at the bottom of the soft bag 6 is discharged from the liquid outlet nozzle 5 through the liquid outlet pipe 7. The liquid outlet nozzle 5 is released, the elastic airbag 3 is restored, and negative pressure is formed in the elastic airbag 3. External air is replenished into the elastic airbag 3 through the upper air replenishing structure 41. Figure 3 shown.

[0033] Embodiment 3: The liquid outlet pipe 7 includes an upper liquid outlet pipe 71 integrally formed with the liquid outlet nozzle 5, and a lower liquid outlet pipe 72 integrally formed with the elastic airbag 3. The lower end of the upper liquid outlet pipe 71 passes through the bottom of the elastic airbag 3 and is inserted into the upper end of the lower liquid outlet pipe 72. An air inlet hole 8 is provided between the bottom of the elastic airbag 3 and the soft bag 6. The air replenishing structure 4 is connected with the air barrier between the soft bag 6 and the bottle body 1. When the liquid outlet nozzle 5 is pressed, the air in the elastic airbag 3 enters the soft bag 6 through the air inlet hole 8. The liquid in the soft bag 6 is squeezed out and discharged through the lower liquid outlet pipe 72, the upper liquid outlet pipe 71 and the liquid outlet nozzle 5 in sequence. The liquid outlet nozzle 5 is released, the elastic airbag 3 is restored, and negative pressure is formed in the elastic airbag 3. The air in the soft bag 6 is replenished into the elastic airbag 3 through the air inlet hole 8, so that the soft bag 6 shrinks, resulting in an increase in the volume of the air barrier between the soft bag 6 and the bottle body 1. The external air is replenished into the air barrier between the soft bag 6 and the bottle body 1 through the air replenishing structure 4 until a state of air pressure balance is reached. Figure 4 shown.

[0034] Embodiment 4: An upper one-way valve 91 for discharging the air in the elastic airbag 3 to the outside is provided at the connection between the elastic airbag 3 and the liquid outlet nozzle 5, and a lower one-way valve 92 for discharging the liquid in the soft bag 6 to the elastic airbag 3 is provided at the bottom of the elastic airbag 3. The elastic airbag 3 itself acts as a liquid outlet pipe, and the air replenishing structure 4 is connected with the air barrier between the soft bag 6 and the bottle body 1. When the liquid outlet nozzle 5 is pressed, the air in the elastic airbag 3 passes through the upper one-way valve 9 1 is discharged to the outside, the liquid outlet nozzle 5 is released, the elastic airbag 3 is restored, a negative pressure is formed in the elastic airbag 3, and the liquid in the soft bag 6 is replenished into the elastic airbag 3 through the lower one-way valve 92. At the same time, the volume of the air barrier between the soft bag 6 and the bottle body 1 increases, forming a negative pressure state, and the external air is replenished into the air barrier between the soft bag 6 and the bottle body 1 through the air replenishing structure 4. At this time, liquid is stored in the elastic airbag 3, and the liquid outlet nozzle 5 can be installed again to discharge the liquid. Figure 5 shown.

[0035] Embodiment 5: The difference from Embodiment 4 is that the elastic airbag 3 is composed of a compression rebound portion and a mounting connection portion located at the bottom of the compression rebound portion. In this embodiment, the compression rebound portion and the mounting connection portion are separate structures. Figure 6 shown.

[0036] Embodiment 6: The difference from Embodiment 5 is that the upper one-way valve 91 and the elastic airbag 3 are separate structures. Figure 7 shown.

[0037] Embodiments 4 and 5: the upper one-way valve 91 and the elastic airbag 3 are integrally formed, and the lower one-way valve 92 and the mounting connection portion are integrally formed. Embodiment 6: the upper one-way valve 91 and the elastic airbag 3 are separate structures, and the lower one-way valve 92 and the mounting connection portion are integrally formed.

[0038] A lotion bottle with a soft bag comprises a repositionable elastic airbag 3, a liquid outlet nozzle 5 is arranged at the liquid outlet of the elastic airbag 3, a soft bag 6 is sealedly mounted at the lower end of the elastic airbag 3, and the soft bag 6 is connected to the liquid outlet nozzle 5 through a liquid outlet pipe 7.

[0039] Embodiment 7: This embodiment has only a soft bag structure but no bottle structure. An upper one-way valve 91 for discharging the air in the elastic air bag 3 to the outside is provided at the connection between the elastic air bag 3 and the liquid outlet nozzle 5. A lower one-way valve 92 for discharging the liquid in the soft bag 6 to the elastic air bag 3 is provided at the bottom of the elastic air bag 3. The elastic air bag 3 itself acts as a liquid outlet pipe. When the liquid outlet nozzle 5 is pressed, the air in the elastic air bag 3 is discharged to the outside through the upper one-way valve 91. When the liquid outlet nozzle 5 is released, the elastic air bag 3 is restored, and negative pressure is formed in the elastic air bag 3. The liquid in the soft bag 6 is replenished into the elastic air bag 3 through the lower one-way valve 92. At the same time, the external air directly squeezes the soft bag 6. At this time, liquid is stored in the elastic air bag 3. The liquid can be discharged by installing the liquid outlet nozzle 5 again. Figure 8 shown.
