Specifically, a first hollow portion 2224 is provided in the center of a side wall of the second replacement component 2223 that is not connected to the lower fixing part 222, and the size of the first hollow portion 2224 matches the size of the first replacement part 123.

[0076] In a specific implementation, when the packaging bottle is completely installed, the first replacement component 123 is located in the first hollow portion 2224 , and other areas of the second replacement component 2223 except the first hollow portion 2224 are respectively located in the second replacement grooves 122 .

[0077] In a specific implementation, the edge of the second replacement component 2223 that is connected to the first hollow portion 2224 can be made into a slightly inclined bevel to guide the installation or disassembly of the second replacement component 2223 and the first replacement component 12.

[0078] Specifically, the second pressing fixing member 23 is an inner shoulder sleeve, and the second pressing fixing member 23 includes an inner fixing member 231 and an outer fixing member 232 which are coaxially arranged, the bottom of the inner fixing member 231 is connected to the bottom of the outer fixing member 232, a first anti-rotation convex 2321 is provided at a position of the outer wall of the outer fixing member 232 corresponding to the first anti-rotation groove 2222; a second convex ring 2322 is provided at a position of the outer wall of the outer fixing member 232 corresponding to the top of the first convex ring 2211;

[0079] In a specific implementation, during installation, a downward force can be applied to the outer shoulder sleeve, or an upward force can be applied to the inner shoulder sleeve, so that the second convex ring 2322 on the inner shoulder sleeve is located above the first convex ring 2211 on the outer shoulder sleeve to achieve positioning and prevent the two from falling off. At this time, the first anti-rotation convex 2321 is located in the first anti-rotation groove 2222 to prevent relative rotation between the outer shoulder sleeve and the inner shoulder sleeve during disassembly.

[0080] The inner wall of the inner fixing member 231 is provided with a first internal thread 2311, the bottom of the inner wall of the inner fixing member 231 is provided with a second hollow portion 2312, and the top surface of the second hollow portion 2312 is provided with a plurality of third boss groups, each of which is provided with two non-connected third bosses 2313, and an indicating groove 2314 is formed between the two third bosses 2313.

[0081] Preferably, in order to make the clamping smoother, the joints of the third boss 2313 can be rounded, or the side of the third boss 2313 can be slightly tilted toward its center for better guidance. At this point, the entire pressing assembly 2 and the replaceable core group 3 are connected or separated through the cooperation of the external thread, the internal thread, the indicating groove 2314 and the indicating boss 3212, and the entire pressing assembly 2 and the outer bottle 1 are connected or separated through the cooperation of the first replacement assembly 12 and the second replacement assembly 2223.

[0083] In a specific implementation, the external thread and the internal thread are gradually matched during the installation process; the indicator groove 2314 and the indicator boss 3212 are gradually positively engaged. During the engagement process, the consumer feels a slight resistance in his hand, which disappears after the full engagement, indicating to the consumer that the installation is complete. Similarly, during the disassembly process, it is necessary to rotate in the opposite direction with force. During the reverse process, the indicator boss 3212 and the indicator groove 2314 are gradually separated. At this time, the consumer also feels resistance, which disappears after the complete separation, indicating to the consumer that the separation of the card slot is complete.

[0084] The outer periphery of the thread cover 321 is provided with a first external thread 3213 matching the first internal thread 2311, and the top of the inner wall of the thread cover 321 is provided with a first fixing groove 3214;

[0088] In a specific implementation, the tooth cover 321 and the middle section 322 can be installed by applying a downward force to the tooth cover 321 after the second anti-rotation groove 3215 is aligned with the second anti-rotation protrusion 32222, so that the first fixed boss 32221 is stuck in the first fixed groove 3214. At this time, the first fixed boss 32221 is located in the first fixed groove 3214, realizing a fixed connection between the middle section 322 and the tooth cover 321.

[0089] Specifically, a third convex ring 32211, a plurality of fourth bosses 32212, and a first sealing ring 32213 are sequentially arranged on the outer wall of the inner liner connecting piece 3221, and a third stop groove 32214 is formed between every two adjacent fourth bosses 32212; in order to avoid the first sealing ring 32213 from blocking and interfering with the fourth limiting boss during the installation process, the thickness of the first sealing ring 32213 must be smaller than the thickness of the fourth boss 32212.

[0090] Specifically, the inner liner assembly 31 includes an inner liner 311 and a piston 312 disposed in the inner liner 311, a fourth convex ring 314 is disposed on the inner wall of the inner liner 311 at a position corresponding to the top of the third convex ring 32211, and a third anti-rotation convex 315 is disposed on the inner wall of the inner liner 311 at a position corresponding to the third anti-rotation groove 32214;

In a specific implementation, the sealing principle of the pump core 33 is mainly the cooperation of the spring and the ball. When the pump head is pressed, the spring is compressed, the pressure increases, and the liquid enters the nozzle cavity through the hole of the valve core. When the pump head is released, the volume in the spring cavity increases, forming a negative pressure, and the ball opens under the action of the negative pressure, allowing the liquid in the bottle to enter the spring cavity, so that the sealed pump core 33 on the market can be applied to this design.

[0094] Preferably, in order to prevent the pressing cap 21 from falling off, a hanging platform 213 is provided at the bottom of the pressing cap 21, and the outer diameter of the hanging platform 213 is larger than the diameter of the outer shoulder sleeve.

[0097] The working principle or working process of a novel replaceable wide-mouth packaging bottle provided by the utility model is as follows:

[0098] When the finished product inner body is used up, it is replaced: hold the outer bottle 1 and forcefully rotate the outer shoulder sleeve (first pressing and fixing member 22) of the packaging bottle, the second replacement component 2223 of the outer shoulder sleeve (first pressing and fixing member 22) leaves the first replacement member 123 of the outer bottle 1, and after the two are separated and leave the second replacement groove 122, the outer shoulder sleeve is lifted up along the first replacement groove 121, and at this time, the pressing component 2 (the pressing component 2 is connected to the replaceable core group 3) is separated from the outer bottle 1;

[0099] Put down the outer bottle 1, hold the inner liner 311, and continue to rotate the outer shoulder sleeve (the first pressing and fixing part 22). The external thread of the tooth cover 321 is separated from the internal thread of the inner shoulder sleeve (the second pressing and fixing part 23) in the pressing component 2, and the pressing component 2 is separated from the replaceable core group 3; discard the replaceable core group 3; take out the unused replacement package, unscrew the replacement core cover 4, screw the internal thread of the inner shoulder sleeve (the second pressing and fixing part 23) into the external thread of the tooth cover 321 in the replaceable core group 3, and the engagement of the indicating groove 2314 and the indicating boss 3212 indicates that the rotation is in place, and then align the second replacement component 2223 in the outer shoulder sleeve (the first pressing and fixing part 22) with the first replacement groove 121, move it down, and then screw it toward the second replacement groove 122. When the second replacement component 2223 is engaged with the first replacement part 123, the replacement is completed.
