The partition 4 is provided between the limit step 11 of the body 1 and the cap 3 to separate the first chamber 101 from the second chamber 201.

The partition 4 includes an air bag 43 and a compressively deformable air bag spring 40, the air bag 43 is mounted on the air bag spring 40, and the air bag 43 cooperates with the air bag spring 40 to form a third chamber 401. When the cap 3 with the nipple 2 is mounted on the bottle body 1, the third chamber 401 is compressed and deformed, and the volume is reduced; the partition 4 is also provided with a connection passage 402 that communicates the first chamber 101 and the second chamber 201.

The bottom of the air bag 43 is provided with a first one-way valve 400, the flow direction of which is controlled by the first one-way valve 400, is that gas enters the second chamber 201 from the third chamber 401.

The bottom part of the air sac 43 extends upwards to form a column 431, the column 431 is positioned in the third chamber 401, and the top end of the column 431 passes through the air sac elastic sheet 40 and is arranged on the air sac elastic sheet 40; the upright post 431 is hollow to form the connecting channel 402, the top end of the connecting channel 402 is provided with a second one-way valve 403, the flow direction controlled by the second one-way valve 403 is that liquid flows from the connecting channel 402 to the first chamber 101, the other end of the connecting channel 402 is connected with a suction pipe 5, and the suction pipe 5 is arranged in the first chamber 101, so that the suction pipe 5 can suck milk from the first chamber 101 and flow to the connecting channel 402.

In use, milk is first filled into the bottle body 1, and then the partition 4 is placed into the opening of the second chamber 201 of the bottle body 1, and the partition 4 is blocked by the limiting step 11 and cannot fall into the second chamber 201. Finally, the nipple 2 connected with the screw cap 3 is arranged on the bottle body 1. When the nipple 2 is installed, the second chamber 201 of the nipple 2 faces the partition 4, the spiral cover 3 presses the partition 4, the first chamber 101 and the second chamber 201 are separated by the partition 4, the spiral cover 3 is screwed, the spiral cover 3 moves towards the bottle body 1 to press the partition 4, the third chamber 401 formed by assembling the air bag elastic sheet 40 and the air bag 43 is pressed and deformed, so that the air pressure in the third chamber 401 is increased, the air in the third chamber 401 washes out the first one-way valve 400, enters the first chamber 101 from the first one-way valve 400, the air pressure in the first chamber 101 is forced to be increased, milk in the bottle body 1 is pressed to enter the connecting channel 402 from the straw 5, the second one-way valve 403 is washed out, and the milk enters the second chamber 201 through the second one-way valve 403.
