During the upward movement of the threaded piston; when the external thread is completely matched with the corresponding thread gap; the fixture block is just deviated to the position matched with the second arc-shaped notch under the action of the extruding square hole. When a person is using the cosmetic packaging bottle designed by the invention; one would press the squeeze piston downward; causing the squeeze piston to move downward; the extrusion piston moves downwards to respectively drive the cylindrical push block and the clamping block to move downwards; the fixture block is contacted with the extrusion square hole in the moving process of the fixture block, so that the fixture block gradually deflects to the center of the threaded piston; simultaneously during the downward movement of the extrusion piston; the extrusion piston can drive the guide push block to move downwards; the guide push block moves to drive the rack to move downwards; since the transmission gear is engaged with the rack and the teeth on the threaded piston, respectively, in the initial state. Therefore, the rack moves downwards to drive the transmission gear to rotate; the transmission gear rotates to drive the threaded piston to move upwards; the threaded piston is arranged on the inner side of the threaded ring through the matching of the three sections of external threads and the internal threads on the threaded ring; the outer circle surface of the upper end of the threaded ring is arranged on the inner circle surface of the cosmetic bottle cap; the threaded piston is rotated when the threaded piston moves upwards; the rotation of the threaded piston can drive the external thread on the threaded piston to rotate; during the upward movement of the threaded piston; the threaded piston drives the transmission shaft to move upwards; the transmission shaft moves upwards to drive the isolation circular plate to move upwards; the isolation circular plate drives the trigger ball to move upwards through the compression spring; so that the trigger ball is separated from the upper end of the extrusion suction pipe; in the invention, one end of the suction tube switch plate, which is not provided with the circular hole, is just matched with the circular hole on the threaded piston in the initial state. Therefore, when the trigger ball moves upwards; when the isolation circular plate moves upwards, negative pressure is generated between the isolation circular plate and the U-shaped circular plate; under the action of the negative pressure, the cosmetics in the cosmetic bottle body gradually flow into the space between the isolation circular plate and the U-shaped circular plate through the extrusion suction pipe; in the invention, the screw piston moves upwards; when the external thread is completely matched with the corresponding thread gap; the transmission gear is just separated from the teeth on the threaded piston. The clamping block just moves to be matched with the second arc-shaped notch. The cylindrical push block just moves to be in contact with the pushing circular ring disc. The circular hole on the sucker switch plate just moves to be matched with the circular hole on the threaded piston under the action of the trigger block. So during the upward movement of the threaded piston; when the external thread is completely matched with the corresponding thread gap; the transmission gear is just separated from the teeth on the threaded piston. The transmission gear can not drive the threaded piston to move upwards; meanwhile, the threaded piston and the pushing circular ring disc are in an integrated state under the action of the clamping block; and the circular hole on the straw switch plate is just moved to be matched with the circular hole on the threaded piston. The extrusion piston moves downwards at the moment, and then the circular ring disc and the threaded piston are driven to move downwards through the cylindrical push block; during the downward movement of the threaded piston; the threaded piston drives the transmission shaft to move downwards; the transmission shaft moves downwards to drive the isolation circular plate to move downwards; the cosmetic between the isolation circular plate and the U-shaped circular plate can be extruded when the isolation circular plate moves downwards; cosmetics between the isolation circular plate and the U-shaped circular plate sequentially pass through the isolation circular plate, the transmission shaft and the circular hole in the threaded piston and flow into the telescopic pipe; cosmetics flowing into the telescopic pipe can flow into the extrusion outlet pipe through the cylindrical push block and the circular holes on the extrusion piston; finally, the mixture flows out through an extrusion port pipe; when the person has finished using the cosmetic; the extrusion piston is loosened; at the moment, under the elastic action of the return spring, the return spring and the elastic fixing plate; the clamping block can be separated from the constraint of the second arc-shaped notch; meanwhile, the elastic force of the return spring is smaller than that of the three return springs. The distance between the extrusion piston and the pushing circular ring disc is increased continuously; namely, the clamping block can be gradually restored to the original position; meanwhile, when the clamping block is disengaged from the second arc-shaped notch; the threaded piston can be restored to the original position under the action of the extension spring; the circular ring disc is pushed to move upwards under the action of the return spring; the trigger block will also move upwards; the trigger block moves upwards to lose the binding of the suction pipe switch plate; the straw switch plate can be restored to the original position under the action of the extrusion spring; therefore, the isolation circular plate and the U-shaped circular plate are in a closed state; the isolating circular plate can extrude the cosmetics between the isolating circular plate and the U-shaped circular plate in the process of recovering the threaded piston; so that the cosmetics between the isolation circular plate and the U-shaped circular plate are squeezed to trigger the ball body; so that the trigger ball is separated from the upper side of the extrusion suction pipe; the cosmetics between the isolation circular plate and the U-shaped circular plate can flow back to the inner side of the cosmetic bottle body through the extrusion suction pipe; thereby preventing the user from squeezing the cosmetics between the separation circular plate and the U-shaped circular plate for use at the next use instead of using the cosmetics stored in the cosmetic bottle. The telescopic pipe designed by the invention has the function of preventing the extrusion piston from interfering with the threaded piston in the downward moving process; preventing cosmetic from flowing between the extruding piston and the threaded piston; affecting the normal use of the extrusion piston and the threaded piston; the elastic force of the return spring designed by the invention is smaller than that of the three return springs, and the function of the return spring is to prevent the extrusion piston from driving and pushing the circular ring disc to move downwards in the initial downward movement process; so that the pushing of the annular disc loses its effect. In the present invention but when the threaded piston is fully displaced to the lowermost side; the threaded piston is restored to the original state of meshing with the transmission gear under the action of the extension spring. In the invention, the elastic force of the compression spring is larger in the downward movement process of the isolation circular plate; the triggering ball may block the upper end of the extrusion straw; therefore, the upper end of the extrusion suction pipe designed by the invention is higher than the round hole on the U-shaped disc; namely, the cosmetics positioned between the isolation circular plate and the U-shaped circular plate are squeezed open to trigger the ball body by the squeezing force in the downward moving process of the isolation circular plate; and then flows back into the cosmetic bottle.

On one hand, when people use the cosmetic packaging bottle designed by the invention, the air pressure protection mechanism can enable cosmetics in the cosmetic bottle body to flow out of the cosmetic bottle more smoothly through high-pressure air in the air storage outer shell and the air storage inner shell; on the other hand, when the cosmetic bottle body is deformed by impact; the cosmetic bottle body can crush the trigger rod; namely the trigger rod loses the constraint on the inner gas storage shell; the air storage inner shell can slide relative to the air storage outer shell; at the moment, the high-pressure air at the upper side in the cosmetic bottle body flows into the inner side of the air storage inner shell through the first high-pressure air hole at the upper side on the cosmetic bottle body and the second high-pressure air hole at the upper side on the air storage outer shell under the action of the extrusion force; then the gas is discharged through a gas release port; the cosmetics in the inner side of the cosmetic bottle body can flow into the inner side of the gas storage inner shell through the first high-pressure gas hole in the lower side of the cosmetic bottle body and the second high-pressure gas hole in the lower side of the gas storage outer shell under the action of the extrusion force; the cosmetics flowing into the inner side of the air storage inner shell can extrude the air storage inner shell to enable the air storage inner shell to move downwards relative to the air storage outer shell; so that the storage space of the air storage outer shell and the air storage inner shell is enlarged; the cosmetics in the cosmetic bottle can completely flow into the air storage outer shell and the air storage inner shell; prevent the loss of cosmetics caused by the extrusion of the cosmetic bottle body.

Therefore, the rack moves downwards to drive the transmission gear to rotate; the transmission gear rotates to drive the threaded piston to move upwards; the threaded piston is arranged on the inner side of the threaded ring through the matching of the three sections of external threads and the internal threads on the threaded ring; the outer circle surface of the upper end of the threaded ring is arranged on the inner circle surface of the cosmetic bottle cap; the threaded piston is rotated when the threaded piston moves upwards; the rotation of the threaded piston can drive the external thread on the threaded piston to rotate; during the upward movement of the threaded piston; the threaded piston drives the transmission shaft to move upwards; the transmission shaft moves upwards to drive the isolation circular plate to move upwards; the isolation circular plate drives the trigger ball to move upwards through the compression spring; so that the trigger ball is separated from the upper end of the extrusion suction pipe; in the invention, one end of the suction tube switch plate, which is not provided with the circular hole, is just matched with the circular hole on the threaded piston in the initial state. Therefore, when the trigger ball moves upwards; when the isolation circular plate moves upwards, negative pressure is generated between the isolation circular plate and the U-shaped circular plate; under the action of the negative pressure, the cosmetics in the cosmetic bottle body gradually flow into the space between the isolation circular plate and the U-shaped circular plate through the extrusion suction pipe; in the invention, the screw piston moves upwards; when the external thread is completely matched with the corresponding thread gap; the transmission gear is just separated from the teeth on the threaded piston.

When a person is using the cosmetic packaging bottle designed by the invention; as shown in fig. 31a, one would press the squeeze piston 6 downward; so that the pressing piston 6 moves downward; as shown in fig. 32a, the downward movement of the extruding piston 6 drives the cylindrical pushing block 10 and the clamping block 21 to move downward respectively; as shown in fig. 32b, when the fixture block 21 contacts the square extrusion hole 32 during the movement of the fixture block 21, the fixture block 21 gradually deflects toward the center of the threaded piston 20; while during the downward movement of the squeezing piston 6; the extrusion piston 6 drives the guide push block 23 to move downwards; the guide push block 23 moves to drive the rack 11 to move downwards; since in the initial state the transmission gear wheel 27 meshes with the toothed rack 11 and the teeth 40 on the threaded piston 20, respectively.

Latch 21 is moved into engagement with second arcuate notch 42. The cylindrical push block 10 is just moved into contact with the pushing circular disc 9. The circular hole 37 in the pipette switch plate 35 is moved into engagement with the circular hole in the threaded piston 20 by the action of the trigger block 12. During the upward movement of the threaded piston 20; as shown in fig. 31b, when the external thread 43 is completely engaged with the corresponding thread gap 44; the transmission gear 27 is just disengaged from the teeth 40 on the threaded piston 20. The transmission gear 27 does not drive the threaded piston 20 to move upwards; as shown in fig. 32c, the screw piston 20 and the pushing ring disc 9 are in an integrated state under the action of the fixture block 21; and the circular hole 37 in the straw switch plate 35 is just moved to fit the circular hole in the threaded piston 20. As shown in fig. 31c, when the pressing piston 6 moves downward, the cylindrical pushing block 10 pushes the circular ring disk 9 and the threaded piston 20 to move downward together; during the downward movement of the threaded piston 20; the threaded piston 20 drives the transmission shaft 14 to move downwards; the transmission shaft 14 moves downwards to drive the isolation circular plate 19 to move downwards; the downward movement of the isolation circular plate 19 squeezes the cosmetic between the isolation circular plate 19 and the U-shaped circular plate 18; so that the cosmetics between the isolation circular plate 19 and the U-shaped circular plate 18 sequentially pass through the isolation circular plate 19, the transmission shaft 14 and the round holes on the threaded piston 20 and flow into the extension pipe 28; the cosmetics flowing into the extension tube 28 flow into the extrusion outlet tube 5 through the cylindrical push block 10 and the circular holes on the extrusion piston 6; finally, the mixture flows out through an extrusion outlet pipe 5; when the person has finished using the cosmetic; the squeezing piston 6 is released; at this time, under the elastic action of the return spring 22, the return spring 33 and the elastic fixing plate 29; the latch 21 is released from the second arc-shaped notch 42; and since the elastic force of the return spring 22 is smaller than the elastic force of the three return springs 33. The distance between the extrusion piston 6 and the pushing ring disc 9 is increased continuously; namely, the fixture block 21 is gradually restored to the original position; when the clamping block 21 is disengaged from the second arc-shaped notch 42; as shown in fig. 31e, the threaded piston 20 is returned to its original position by the tension spring 17; the annular disc 9 is pushed to move upwards under the action of the return spring 33; the trigger block 12 will also move upwards; the trigger block 12 moves upwards to lose the binding of the straw switch plate 35; the straw switch plate 35 is restored to the original position by the pressing spring 39; so that the space between the isolation circular plate 19 and the U-shaped circular plate 18 is closed at this time; while the isolating circular plate 19 will squeeze the cosmetic between the isolating circular plate 19 and the U-shaped circular plate 18 during the recovery of the threaded piston 20; so that the cosmetic product between the separation disc 19 and the U-shaped disc 18 squeezes the trigger sphere 16; so that the trigger sphere 16 is disengaged from the upper side of the squeeze pipette 7; as shown in fig. 31d, the cosmetics between the separation circular plate 19 and the U-shaped circular plate 18 flow back to the inside of the cosmetic bottle 2 by pressing the suction pipe 7; thereby preventing the user from squeezing out the cosmetics between the separation circular plate 19 and the U-shaped circular plate 18 for use at the next use instead of using the cosmetics stored in the cosmetic bottle body 2. The telescopic tube 28 designed by the invention has the function of preventing the extrusion piston 6 from interfering with the threaded piston 20 in the process of moving downwards; preventing cosmetic from flowing between the extruding piston 6 and the screw piston 20; affecting the normal use of the extruding piston 6 and the threaded piston 20; the elastic force of the return spring 22 designed by the invention is smaller than the elastic force of the three return springs 33, and the function of the return spring is to prevent the extrusion piston 6 from driving and pushing the circular ring disc 9 to move downwards in the initial downward movement process; so that the annular disc 9 is pushed out of its way. In the present invention but with the threaded piston 20 fully displaced to the lowermost side; the threaded piston 20 is restored to the initial engagement with the transmission gear 27 by the action of the extension spring 17. In the invention, the force of the compression spring 15 is larger in the downward movement process of the isolation circular plate 19; the trigger ball 16 may block the upper end of the squeeze pipette 7; therefore, the upper end of the extrusion suction pipe 7 designed by the invention is higher than the round hole on the U-shaped disc 18; namely, the cosmetics located between the separation circular plate 19 and the U-shaped circular plate 18 are pushed away from the trigger ball 16 by the pressing force during the downward movement of the separation circular plate 19; and then flows back into the cosmetic bottle.

On one hand, when people use the cosmetic packaging bottle designed by the invention, the air pressure protection mechanism 54 can ensure that the cosmetics in the cosmetic bottle body 2 flow out of the cosmetic bottle more smoothly through the high-pressure air in the air storage outer shell 47 and the air storage inner shell 53; on the other hand, when the cosmetic bottle body 2 is deformed by impact; the cosmetic bottle body 2 crushes the trigger lever 50; namely, the trigger rod 50 loses the constraint of the inner gas storage shell 53; the air storage inner shell 53 can slide relative to the air storage outer shell 47; at this time, the high-pressure air inside the cosmetic bottle 2 at the upper side flows into the inner side of the air storage inner shell 53 through the first high-pressure air hole 48 at the upper side on the cosmetic bottle 2 and the second high-pressure air hole 51 at the upper side on the air storage outer shell 47 under the action of the extrusion force; then discharged through the gas discharge port 52; the cosmetics inside the cosmetic bottle 2 will flow into the inside of the inner gas storage shell 53 through the first high-pressure gas hole 48 on the lower side of the cosmetic bottle 2 and the second high-pressure gas hole 51 on the lower side of the outer gas storage shell 47 under the effect of the squeezing force; the cosmetics flowing into the inner side of the inner air container 53 press the inner air container 53 such that the inner air container 53 moves downward relative to the outer air container 47; thereby enlarging the storage space of the air storage outer shell 47 and the air storage inner shell 53; so that the cosmetics in the cosmetic bottle 2 can completely flow into the air storage outer shell 47 and the air storage inner shell 53; the loss of the cosmetics due to the squeezing of the cosmetic bottle body 2 is prevented.

The specific implementation mode is as follows: when a person is using the cosmetic packaging bottle designed by the invention; one would press the squeeze piston 6 downward; so that the pressing piston 6 moves downward; the extrusion piston 6 moves downwards to respectively drive the cylindrical push block 10 and the clamping block 21 to move downwards; when the fixture block 21 contacts the extruding square hole 32 in the moving process of the fixture block 21, the fixture block 21 gradually deflects to the center of the threaded piston 20; while during the downward movement of the squeezing piston 6; the extrusion piston 6 drives the guide push block 23 to move downwards; the guide push block 23 moves to drive the rack 11 to move downwards; since in the initial state the transmission gear wheel 27 meshes with the toothed rack 11 and the teeth 40 on the threaded piston 20, respectively. The rack 11 moves downwards to drive the transmission gear 27 to rotate; the transmission gear 27 rotates to drive the threaded piston 20 to move upwards; the threaded piston 20 is arranged inside the threaded ring 13 through the matching of the three sections of external threads 43 and the internal threads 45 on the threaded ring 13; the outer circle surface of the upper end of the threaded ring 13 is arranged on the inner circle surface of the cosmetic bottle cap 4; the threaded piston 20 is rotated when the threaded piston 20 moves upward; the rotation of the threaded piston 20 drives the external thread 43 on the threaded piston 20 to rotate; during the upward movement of the threaded piston 20; the threaded piston 20 will drive the transmission shaft 14 to move upwards; the transmission shaft 14 moves upwards to drive the isolation circular plate 19 to move upwards; the isolation circular plate 19 drives the trigger ball 16 to move upwards through the compression spring 15; so that the trigger sphere 16 is disengaged from the upper end of the squeeze bulb 7; in the present invention, the end of the pipette switch plate 35 not having the circular hole 37 in the initial state is just engaged with the circular hole of the threaded piston 20. So during the upward movement of the trigger sphere 16; the upward movement of the isolation circular plate 19 causes a negative pressure to be generated between the isolation circular plate 19 and the U-shaped circular plate 18; under the action of the negative pressure, the cosmetics in the cosmetic bottle body 2 gradually flow into the space between the isolation circular plate 19 and the U-shaped disc 18 through the extrusion suction pipe 7; since the present invention is in the process of the upward movement of the threaded piston 20; when the external thread 43 is completely engaged with the corresponding thread gap 44; the transmission gear 27 is just disengaged from the teeth 40 on the threaded piston 20. Latch 21 is moved into engagement with second arcuate notch 42. The cylindrical push block 10 is just moved into contact with the pushing circular disc 9. The circular hole 37 in the pipette switch plate 35 is moved into engagement with the circular hole in the threaded piston 20 by the action of the trigger block 12. During the upward movement of the threaded piston 20; when the external thread 43 is completely engaged with the corresponding thread gap 44; the transmission gear 27 is just disengaged from the teeth 40 on the threaded piston 20. The transmission gear 27 does not drive the threaded piston 20 to move upwards; meanwhile, under the action of the fixture block 21, the threaded piston 20 and the pushing circular ring disc 9 are in an integrated state; and the circular hole 37 in the straw switch plate 35 is just moved to fit the circular hole in the threaded piston 20. Namely, the extrusion piston 6 moves downwards at the moment, and the circular ring disc 9 and the threaded piston 20 are driven to move downwards through the cylindrical push block 10; during the downward movement of the threaded piston 20; the threaded piston 20 drives the transmission shaft 14 to move downwards; the transmission shaft 14 moves downwards to drive the isolation circular plate 19 to move downwards; the downward movement of the isolation circular plate 19 squeezes the cosmetic between the isolation circular plate 19 and the U-shaped circular plate 18; so that the cosmetics between the isolation circular plate 19 and the U-shaped circular plate 18 sequentially pass through the isolation circular plate 19, the transmission shaft 14 and the round holes on the threaded piston 20 and flow into the extension pipe 28; the cosmetics flowing into the extension tube 28 flow into the extrusion outlet tube 5 through the cylindrical push block 10 and the circular holes on the extrusion piston 6; finally, the mixture flows out through an extrusion outlet pipe 5; when the person has finished using the cosmetic; the squeezing piston 6 is released; at this time, under the elastic action of the return spring 22, the return spring 33 and the elastic fixing plate 29; the latch 21 is released from the second arc-shaped notch 42; and since the elastic force of the return spring 22 is smaller than the elastic force of the three return springs 33. The distance between the extrusion piston 6 and the pushing ring disc 9 is increased continuously; namely, the fixture block 21 is gradually restored to the original position; when the clamping block 21 is disengaged from the second arc-shaped notch 42; the threaded piston 20 will return to its original position under the action of the tension spring 17; the annular disc 9 is pushed to move upwards under the action of the return spring 33; the trigger block 12 will also move upwards; the trigger block 12 moves upwards to lose the binding of the straw switch plate 35; the straw switch plate 35 is restored to the original position by the pressing spring 39; so that the space between the isolation circular plate 19 and the U-shaped circular plate 18 is closed at this time; while the isolating circular plate 19 will squeeze the cosmetic between the isolating circular plate 19 and the U-shaped circular plate 18 during the recovery of the threaded piston 20; so that the cosmetic product between the separation disc 19 and the U-shaped disc 18 squeezes the trigger sphere 16; so that the trigger sphere 16 is disengaged from the upper side of the squeeze pipette 7; and then the cosmetics between the isolation circular plate 19 and the U-shaped circular plate 18 flow back to the inner side of the cosmetic bottle body 2 through the squeezing suction pipe 7; thereby preventing the user from squeezing out the cosmetics between the separation circular plate 19 and the U-shaped circular plate 18 for use at the next use instead of using the cosmetics stored in the cosmetic bottle body 2.
