The outer side wall of the upper end opening of the outer bottle 5 is provided with a clamping block 52, and the inner wall of the shoulder sleeve 6 is provided with a clamping groove 62 corresponding to the clamping block 52. The clamping block 52 and the clamping groove 62 form a limit in the vertical direction between the outer bottle 5 and the shoulder sleeve 6, so that the shoulder sleeve 6 can be fixedly installed on the outer bottle 5.

[0038] like Figure 2 , 12 As shown, the press head 7 includes a connecting tube 71 and a ring plate 72. The press head 7 is installed at the upper end of the pump core 2. The lower end portion of the connecting tube 71 is inserted into the upper end of the pump core 2. The connecting tube 71 can be detachably plugged in and out of the pump core 2. The press head 7 is coaxially arranged with the shoulder sleeve 6. The press head 7 can slide up and down along the shoulder sleeve 6. The ring plate 72 extends toward the shoulder sleeve 6. The lower end of the ring plate 72 is at least partially located in the shoulder sleeve 6. A shoulder 63 is provided on the inner wall of the upper end opening of the shoulder sleeve 6. A stop block 721 is provided on the outer wall of the ring plate 72. The stop block 721 is located below the shoulder 63. The shoulder 63 forms an upward limit for the stop block 721. The diameter of the upper end of the press head 7 is larger than the inner diameter of the shoulder sleeve 6. The upper end of the press head 7 limits the lowermost position of the press head 7.

[0039] More preferably, a notch 722 is provided at the lower end of the ring plate 72, and the notch 722 is connected to the lower end surface of the ring plate 72. The notch 722 can provide an elastic annular space for the lower end of the ring plate 72, so that the portion of the ring plate 72 provided with the stop block 721 can pass over the stop shoulder 63 and be inserted into the shoulder sleeve 6. The upper end of the notch 722 is lower than the upper end surface of the shoulder sleeve 6. When the button 7 is at the uppermost position, the notch 722 will not be exposed to the outside of the shoulder sleeve 6, which can be more beautiful.

[0040] like Figure 1 , 2 As shown, it includes an outer cover 8, which is installed on the shoulder cover 6. The outer cover 8 is fixed to the shoulder cover 6 by a snap connection, and the outer cover 8 plays a role in protecting the button 7.

[0041] like Figure 2 , 4As shown in Figures 3 and 5, the inner bottle 1 of the packaging bottle of this embodiment includes a first state, a second state, and a third state. In the first state, the inner bottle 1 is fixedly installed inside the outer bottle, the pressing head 7 can be used normally, the inner bottle 1 is in the highest position, the inner wall of the shoulder sleeve 6 forms a limit for the upward position of the pump sleeve 3, the pump sleeve 3 and the outer bottle 5 are fixedly connected by threads, the pump sleeve 3 is against the shoulder sleeve 6, and the entire packaging bottle is in a state of installation; the inner bottle 1 is moved from the first state to the second state by rotating the base 4. In the second state, the pump sleeve 3 is disengaged from the threads of the outer bottle 5, and the positions of the inner bottle 1, the pump core 2, the pump sleeve 3, the base 4, and the pressing head 7 are lower than those in the first state. The connecting pipe 71 and the pump core 2 are still connected; by applying downward force to the base, the inner bottle 1 is moved from the second state to the third state. Since the pressing head 7 will be pressed by the upper end of the shoulder sleeve 6 during the process of pulling out the inner bottle downward, the inserted connecting pipe 71 and the pump core 2 will be disengaged by force. The pressing head 7 in the third state is disengaged from the pump core 2. The inner bottle 1, the pump core 2, the pump sleeve 3, and the base 4 can be taken out downward for replacement. When installing the replacement package, the pressing head can be pressed downward to install the replacement package on the outer bottle 5. First, the pump core 2 is connected to the connecting pipe 71, and then the base 4 is rotated to tighten the thread to install the inner bottle 1 from the third state to the first state.

[0042] like Fig.12 As shown, the replacement package of this embodiment includes an inner bottle 1, a pump core 2, a pump sleeve 3, a base 4, and an inner cover 9. The inner bottle 1, the pump core 2, the pump sleeve 3, and the base 4 are connected in the above-mentioned manner. A convex ring 91 is provided at the lower end of the inner cover 9. The convex ring 91 is plugged into the upper end of the pump core 2. The inner cover 9 can close the upper end opening of the shoulder sleeve 6.
