[0050] Example 1:

[0051] As Figures 1-7As shown, the embodiment provides a self-shrinking cosmetic packaging bottle, comprising: a soft liquid bag 1, a liquid pump 2 and a hard shell 3; the liquid pump 2 is inserted into the liquid bag opening 11 of the soft liquid bag 1; the soft liquid bag 1 is located in the hard shell 3; the liquid pump 2 comprises a pump body 21 and a pump frame 22; the pump body 21 is inserted into the pump frame 22; the pump frame 22 is inserted into the soft liquid bag 1 along the liquid bag opening 11; the pump frame 22 comprises a liquid inlet barrel 221, the liquid inlet barrel 221 is located in the soft liquid bag 1, and a liquid inlet hole 223 is arranged on the side wall of the liquid inlet barrel 221; the liquid suction end 211 of the pump body 21 is inserted into the liquid inlet barrel 221; the liquid enters the pump body 21 along the liquid inlet hole 223 under the action of the pump body 21, and the top of the liquid inlet barrel 221 extends outwardly with a support column 222; the support column 222 is located on the inner bottom of the hard shell 3; the volume of the soft liquid bag 1 gradually decreases as the liquid in the soft liquid bag 1 is pumped out by the liquid pump 2, thereby causing the soft liquid bag 1 to shrink towards the liquid bag opening 11.

[0052] In the use process of the conventional cosmetic packaging bottle, since the hard packaging shell is generally used, the liquid surface of the liquid tank will gradually decrease as the liquid is continuously used, and the liquid pump 2 for pumping the liquid must have its liquid suction end 211 located below the liquid surface to realize liquid suction, thereby causing some liquid to be unable to be pumped by the liquid pump 2.

[0053] The product using the packaging bottle described in the embodiment can use a material such as silica gel which has good elasticity. At the time of leaving the factory, the soft liquid bag 1 is filled with liquid, at this time, the soft liquid bag 1 is tightly attached to the inner wall of the hard shell 3 due to the volume expansion. In the use process, the user presses out the liquid by the liquid pump 2, since the liquid in the soft liquid bag 1 is pumped out by the liquid pump 2 at this time, the liquid in the soft liquid bag 1 gradually decreases, thereby causing the soft liquid bag 1 to gradually shrink, and since the soft liquid bag 1 gradually shrinks, the liquid surface can always be maintained at a relatively high level, thereby causing the liquid suction end 211 of the liquid pump 2 to be below the liquid surface in most cases, and the liquid can be smoothly pumped out by the liquid pump 2.

[0054] At the same time, in order to avoid the liquid from being in an inverted V shape after shrinking due to the gravity of the liquid, and the liquid surface still being lower, in addition to the liquid bag made of silica gel, a device for supporting the liquid bag should also be provided, that is, the support column 222 extending outwardly from the top of the liquid inlet barrel 221, through the support column 222, the length of the liquid pump 2 in the longitudinal direction is increased, thereby supporting the liquid bag, causing the liquid bag to be relatively narrow in the transverse direction, thereby increasing the height of the liquid surface, and further improving the full use of the liquid.

[0055] The embodiment reduces the falling speed of the liquid surface by the cooperation of the supporting column 222, the soft liquid bag 1 and the hard shell 3, and improves the use efficiency of the liquid under the premise of not damaging the storage conditions of the liquid.

[0056] Embodiment 2:

[0057] As shown in Figure 3 , 4 , the embodiment provides a self-shrinking cosmetic packaging bottle, based on embodiment 1, comprising: the soft liquid bag 1 is fixed in the hard shell 3 through the fixing ring 4; the fixing ring 4 extends inward along the inner ring edge of the fixing ring 4 to form a liquid bag connecting part 41, the liquid bag connecting part 41 is embedded in the liquid bag opening 11, and the hard shell 3 is connected with the fixing ring 4 to fix the soft liquid bag 1 and the fixing ring 4.

[0058] In the embodiment, the specific connection mode of the hard shell 3 and the soft liquid bag 1 is realized by arranging the fixing ring 4 at the bag opening of the soft liquid bag 1 and the bottle opening of the hard shell 3, fixing the bag opening and the bottle opening on the fixing ring 4, and thus restraining the soft liquid bag 1 in the hard shell 3. Through the cylindrical device similar to the liquid bag connecting part 41, on the one hand, the opening of the soft liquid bag 1 is supported to avoid shrinking under the action of elasticity, and on the other hand, the bag opening of the soft liquid bag 1 is fixed in cooperation with the inner wall of the hard shell 3.

[0059] Preferably, the hard shell 3 extends outward along the opening of the hard shell 3 to form a shell bottle opening 31; the shell bottle opening 31 is embedded in the shell connecting groove 42 to be connected with the fixing ring 4. The outer side of the liquid bag connecting part 41 is provided with a liquid bag protrusion 411; the inner wall of the shell bottle opening 31 is provided with a shell inner protrusion 311; the outer wall of the liquid bag connecting part 41 is provided with a friction member; the liquid bag protrusion 411 is embedded between the liquid bag connecting part 41 and the shell inner protrusion 311.

[0060] In a specific implementation, a shell connecting groove 42 is arranged on the side of the fixing ring 4 facing the hard shell 3, and the hard shell 3 is connected to the fixing ring 4 by embedding the shell bottle mouth 31 into the shell connecting groove 42. Meanwhile, an inner shell protrusion 311, i.e. an inward screw thread, is arranged on the inner wall of the shell bottle mouth 31, and a friction member is arranged on the outer wall of the medicine bag connecting part 41 to increase the friction force, so that the protrusion arranged on the medicine bag mouth is clamped between the medicine bag connecting part 41 and the inner shell protrusion 311, thereby improving the fixing effect.

[0061] Further preferably, the hard shell 3 comprises a pair of hard half shells corresponding to each other, and the hard half shells are provided with a half shell connecting pin and a corresponding half shell connecting hole at the position of the shell bottle mouth 31; the hard half shells are connected through the half shell connecting pin and the half shell connecting hole.

[0062] In a specific processing and production mode, the soft medicine bag 1 is first placed between a pair of hard half shells corresponding to each other, the hard half shells are connected through the half shell connecting pin and the corresponding half shell connecting hole, and then ultrasonic welding is performed.

[0063] Embodiment 3:

[0064] As shown in Figure 5 , 6 The present embodiment provides a self-shrinking cosmetic packaging bottle, based on embodiment 1, comprising:

[0065] The medicine pump 2 further comprises a pump body pressing member 23 arranged on the pump frame 22 and inserted into the pump body 21; the pump frame 22 further comprises a pressing connecting member 24 for connecting the pump body pressing member 23; the pressing connecting member 24 is provided with a pump lock moving groove 241, and the pump lock moving groove 241 comprises a locking moving groove 2411 and an unlocking moving groove 2412; the height of the unlocking moving groove 2412 is lower than that of the locking moving groove 2411; the pump body pressing member 23 is provided with a pump lock moving pin 231, and the pump lock moving pin 231 moves in the pump lock moving groove 241;

[0070] Preferably, the liquid medicine pump 2 further comprises a pump frame rotating ring 25, which can rotate under the action of external force to adjust the relative position between the pump lock moving pin 231 and the pump lock moving groove 241; the pressing connecting piece 24 is further provided with a rotating connecting protrusion 2242; the pump frame rotating ring 25 is provided with a rotating power member 251 corresponding to the rotating connecting protrusion 2242 for fixed connection of the pressing connecting piece 24.

[0071] In the specific state conversion mode, the pump frame 22 is rotated by rotating the pump frame rotating ring 25, so as to move the pump lock moving groove 241. When unlocked, the unlocking moving groove 2412 is moved below the pump lock moving pin 231, thereby providing the stroke for the downward movement of the pump lock moving pin 231; when locked, the locking moving groove 2411 is moved below the pump lock moving pin 231, thereby locking the pump lock moving pin 231 and avoiding its downward movement.

[0072] In this embodiment, by arranging moving grooves with different heights, whether the pump lock moving pin 231 can move downward is controlled, thereby realizing the locking and unlocking of the pump body 21.
