[0046] Referring to Figures 2-5 , Figures 13-14 , the pressing head 9 is clamped at the upper end of the pump body 601, that is, the pressing head 9 is installed at the upper end of the pump body 601, and the pressing head 9 can be separated upward and downward from the pump body 601 or clamped together upward and downward by external force.

[0047] The piston 603 is interference-fitted on the inner side wall of the inner container 6, the bottom cover 7 is installed at the lower part of the inner container 6, the bottom cover 7 drives the inner container 6 to move upward and downward, the bottom cover 7 comprises a bottom plate 71 and an inner ring 74, the bottom plate 71 abuts upward on the rotating sleeve 3, and the inner ring 74 extends inward to the inside of the inner container 6 and abuts on the lower end of the piston 603.

[0048] The shoulder sleeve 4 is installed on the upper part of the bottle body 1, the bottle cap 5 is installed on the shoulder sleeve 4, and the bottle cap 5 covers the press head 9.

[0049] The connecting sleeve 2 is integrally formed with the bottle body 1, and the connecting sleeve 2 is located at the lower part of the bottle body 1. Alternatively, the connecting sleeve 2 and the bottle body 1 can be two independent components, and the connecting sleeve 2 is installed at the lower part of the bottle body 1.

[0050] Specifically, referring to Figure 6 , the connecting sleeve 2 includes an upper ring 21 and a lower ring 22. The upper ring 21 is fixed to the inner side of the bottle body 1. The upper ring 21 is arranged to prevent relative rotation between the connecting sleeve 2 and the bottle body 1.

[0051] Referring to Figure 2 , Figure 6 , Figure 11 , the rotating sleeve 3 is rotatably installed on the connecting sleeve 2. The lower ring 22 extends downward and extends into the rotating sleeve 3. The rotating sleeve 3 is located on the outer periphery of the lower ring 22 and rotates around the lower ring 22.

[0052] The bottom cover 7 includes an annular sleeve 72 extending upward. The lower ring 22 extends downward between the annular sleeve 72 and the rotating sleeve 3. The annular sleeve 72 is cylindrical. The inner periphery of the lower ring 22 is adapted to the outer periphery of the annular sleeve 72. The annular sleeve 72 can rotate circumferentially along the inner periphery of the lower ring 22.

[0053] Referring to Figure 2 , Figure 4 , Figure 6 , the connecting sleeve 2 includes a clamping strip one 24. The clamping strip one 24 is located on the outer side of the lower ring 22 and is arranged horizontally. The rotating sleeve 3 includes a clamping strip two 33 adapted to the clamping strip one 24. The rotating sleeve 3 can rotate horizontally along the length direction of the clamping strip one 24.

[0054] Specifically, the rotating sleeve 3 is installed upward on the connecting sleeve 2 until the clamping strip two 33 abuts against the upper end of the clamping strip one 24. At this time, the rotating sleeve 3 abuts against the lower end of the bottle body 1 upward. The downward movement of the rotating sleeve 3 is limited by the clamping strip one 24. That is, the upward and downward movement of the rotating sleeve 3 is limited by the cooperation of the bottle body 1 and the clamping strip one 24. Therefore, the rotating sleeve 3 can only rotate forward or reverse along the length direction of the clamping strip one 24.

[0055] Referring to Figures 6-11 , the connecting sleeve 2 includes a sliding groove 23. The sliding groove 23 is arranged on the side surface of the lower ring 22. The bottom cover 7 includes a protruding column 73 adapted to the sliding groove 23. The protruding column 73 is arranged on the outer side of the annular sleeve 72. The number of the protruding column 73 and the sliding groove 23 is two and arranged one by one.

[0056] Referring toFigure 1 , Figures 6-11 As shown, the rotating sleeve 3 includes a stop block 32, which is located on the inner side of the rotating sleeve 3. The connecting sleeve 2 includes at least two protrusions 25, which are located on the outer side of the lower ring 22 and extend outward. The stop block 32 abuts against the protrusions 25 to limit the forward or reverse rotation of the rotating sleeve 3.

[0057] refer to Figure 1 , Figure 6 As shown, the rotation angle of the rotating sleeve 3 is less than or equal to 120 degrees, that is, the maximum rotation angle of the rotating sleeve 3 is 120 degrees. The rotating sleeve 3 is rotated to move the protruding post 73 to the lower end or the upper end of the sliding groove 23. Specifically, when the rotating sleeve 3 rotates 120 degrees until the abutment block 32 abuts against the protruding block 25, the protruding post 73 moves to the upper end of the sliding groove 23; when the rotating sleeve 3 rotates 120 degrees in the opposite direction until the abutment block 32 abuts against the protruding block 25, the protruding post 73 moves to the lower end of the sliding groove 23.

[0058] The rotating sleeve 3 includes a notch 34, which corresponds one-to-one with the protrusion 25. The notch 34 is provided to prevent the protrusion 25 from interfering with the installation of the rotating sleeve 3 and the connecting sleeve 2 when the rotating sleeve 3 is installed upwards.

[0059] The chute 23 includes a lowermost opening 231 and an uppermost end section 234. The opening 231 and the end section 234 are interconnected. The opening 231 extends downward through the connecting sleeve 2, that is, the opening 231 extends downward and through the lower end face of the lower ring 22. At least one inclined section 233 is provided between the opening 231 and the end section 234. A horizontal section 232 is horizontally provided at the lowermost end of the inclined section 233. The horizontal section 232 extends horizontally to the opening 231. The opening 231 is located at the end of the horizontal section 232 away from the inclined section 233. The horizontal section 232 is lower than the end section 234.

[0060] When the rotating sleeve 3 rotates forward until the abutment block 32 abuts against the protrusion 25, the protrusion 73 moves to the lower end of the slide groove 23, that is, the protrusion 73 moves to the opening 231; when the rotating sleeve 3 rotates in the reverse direction until the abutment block 32 abuts against the protrusion 25, the protrusion 73 moves to the upper end of the slide groove 23, that is, the protrusion 73 moves to the end section 234.

[0061] Rotate the rotating sleeve 3 to move the protruding post 73 inclined downward along the slide groove 23 to the lower end of the slide groove 23. That is, the protruding post 73 moves sequentially along the end section 234, the inclined section 233, and the horizontal section 232. During the process of the protruding post 73 moving inclined downward from the inclined section 233 to the horizontal section 232, the bottom cover 7 moves downward with the protruding post 73 to drive the replacement inner bottle downward. The bottom cover 7 extends downward out of the rotating sleeve 3 (see reference). Figure 9 , Figure 12 (The state shown).

[0062] Referring to Figure 13 , Figure 14 , the bottle body 1 includes a boss 12, when the convex column 73 moves to the horizontal section 232, the lower end of the press head 9 is close to the upper end surface of the boss 12, and the downward movement of the press head 9 is limited.

[0063] By rotating the rotating sleeve 3 to move the convex column 73 to the horizontal section 232, that is, the convex column 73 moves from the end section 234 to the horizontal section 232, at this time the press head 9 is still connected with the pump body 601, and the lower end of the press head 9 is close to the upper end surface of the boss 12, that is, the pump body 601 is locked, avoiding the downward mis-pressing of the press head 9, which causes the pump body 601 to pump out the cosmetics in the inner container 6.

[0064] Referring to Figure 9 , Figure 10 , as the convex column 73 continues to move along the horizontal section 232 to the opening 231, the part of the bottom cover 7 that protrudes from the rotating sleeve 3 is pinched and moved downward to take out the replacement inner bottle from the bottle body 1, and because the press head 9 abuts against the boss 12 and cannot continue to move downward with the pump body 601, the press head 9 and the pump body 601 can be separated upward and downward.

[0065] The rotating sleeve 3 includes a clamping groove 31 located on the inner side surface of the rotating sleeve 3, and the convex column 73 penetrates the sliding groove 23 and extends into the clamping groove 31, that is, the convex column 73 penetrates the sliding groove 23 and extends to the rotating sleeve 3, the rotating sleeve 3 is rotated and drives the bottom cover 7 to rotate, when the convex column 73 moves upward and downward along the sliding groove 23, the convex column 73 can move upward and downward in the clamping groove 31, and when the convex column 73 moves to the opening 231 and moves downward with the bottom cover 7, the convex column 73 can be separated from the rotating sleeve 3 downward from the lower end of the clamping groove 31.

[0066] When the convex column 73 moves to the opening 231 along the sliding groove 23, the bottom cover 7 can drive the replacement inner bottle to move downward to separate the press head 9 and the pump body 601 upward and downward, so that the replacement inner bottle can be taken out from the bottle body 1 downward.

[0067] By moving the replacement inner bottle upward to move into the bottle body 1 until the convex column 73 extends upward into the sliding groove 23 through the opening 231, the rotating sleeve 3 is reversely rotated to move the convex column 73 upward along the sliding groove 23 to the upper end of the sliding groove 23, and the bottom cover 7 is retracted upward into the rotating sleeve 3, that is, the convex column 73 moves along the horizontal section 232, the inclined section 233, and the end section 234 in sequence, and in the process that the convex column 73 moves upward along the inclined section 233 to the end section 234, the bottom cover 7 moves upward with the convex column 73 to drive the replacement inner bottle to move upward, so as to connect the pump body 601 upward to the press head 9 (referring to Figure 2 , Figure 8When the replacement inner bottle is replaced, the replacement of the replacement inner bottle is completed, and the replacement inner bottle can be replaced without disassembling other components, so that the replacement operation of the inner container 6 is more convenient.

[0068] Reference Figure 6 , Figure 12 As shown, the clamping groove 31 comprises a stop plate 311 and a channel 312. The stop plate 311 is located at the lower part of the clamping groove 31 and is transversely arranged in the clamping groove 31. The channel 312 is arranged on one side of the stop plate 311. When the protruding column 73 moves to the opening 231, the protruding column 73 is located above the stop plate 311. The bottom cover 7 is moved downward to make the protruding column 73 downwardly separate from the opening 231 until the protruding column 73 downwardly abuts against the stop plate 311. The bottom cover 7 is rotated to make the protruding column 73 move to the channel 312. The protruding column 73 can move downward with the bottom cover 7 and separate from the rotating sleeve 3 from the lower end of the channel 312.

[0069] The stop plate 311 and the channel 312 are arranged in cooperation, so that the protruding column 73 cannot directly separate from the rotating sleeve 3 when the pump body 601 is in the locked state. The protruding column 73 needs to move downward through the channel 312 to detach the replacement inner bottle downward, so that the replacement inner bottle can be more reliably installed in the bottle body 1.

[0070] Reference Figure 2 , Figure 3 As shown, the bottle body 1 comprises an upwardly extending bottle mouth 11, which is located on the inner side of the boss 12. The press head 9 has a spring 901 arranged therein, which is sleeved on the outer periphery of the bottle mouth 11. One end of the spring 901 abuts against the bottle body 1, and the other end of the spring 901 abuts against the press head 9. The spring 901 always abuts upwardly against the press head 9.

[0071] The shoulder sleeve 4 comprises an inwardly extending protruding ring one 41, and the press head 9 comprises an outwardly extending protruding ring two 91. When the protruding column 73 moves to the upper end of the sliding groove 23, that is, the protruding column 73 moves to the last section 234, the spring 901 pushes the press head 9 to move upwardly until the protruding ring two 91 approaches the lower end surface of the protruding ring one 41, and the upward movement of the press head 9 is limited.

[0072] Since the spring 901 always abuts upwardly against the press head 9, the press head 9 is connected to the pump body 601. By rotating the rotating sleeve 3 to make the protruding column 73 move from the horizontal section 232 to the inclined section 233, under the upward force of the spring 901, the press head 9 drives the replacement inner bottle to quickly move upwardly, so that the protruding column 73 quickly moves from the inclined section 233 to the last section 234, that is, the pump body 601 changes from the original locked state to the state that can be pressed for use, so that the switching use of the pump body 601 is more convenient, and the hand feeling during switching is better.

The stop plate (311) is located at the lower part of the slot (31), and the channel (312) is opened on one side of the stop plate (311). When the protrusion (73) moves to the opening (231), the protrusion (73) is located above the stop plate (311). The bottom cover (7) is moved downward to make the protrusion (73) disengage downward from the opening (231) until the protrusion (73) abuts against the stop plate (311). The bottom cover (7) is rotated to make the protrusion (73) move to the channel (312). The protrusion (73) can move downward with the bottom cover (7) and disengage downward from the lower end of the channel (312) from the rotating sleeve (3).

5. The replaceable packaging bottle as described in claim 1, characterized in that: Includes a shoulder sleeve (4) and a bottle cap (5). The shoulder sleeve (4) is installed on the upper part of the bottle body (1), and the bottle cap (5) is installed on the shoulder sleeve (4). The bottle body (1) includes an upwardly extending bottle mouth (11). A spring (901) is placed inside the pusher (9). The spring (901) is sleeved on the outer periphery of the bottle mouth (11). One end of the spring (901) abuts against the bottle body (1), and the other end of the spring (901) abuts against the pusher (9). The shoulder sleeve (4) includes an inwardly extending convex ring one (41), and the pusher (9) includes an outwardly extending convex ring two (91). When the convex post (73) moves to the upper end of the slide groove (23), the spring (901) pushes the pusher (9) to move upward until the convex ring two (91) is close to the lower end face of the convex ring one (41).

6. The replaceable packaging bottle as described in claim 1, characterized in that: The replacement inner bottle also includes an inner shoulder sleeve (8), which is installed on the upper part of the inner liner (6) and presses the pump body (601) against the inner liner (6) downward.
