[0029] In order to enable those skilled in the art of the present technology to better understand the technical solution of the present utility model, the following will describe its specific embodiment in detail with reference to the accompanying drawings:

[0030] Please refer to Figures 1 to 7 , the best embodiment of the present utility model, a replaceable vacuum packaging bottle, which includes a main product cover 13, a pressing cap 11, a spring 10, a shoulder sleeve assembly, an outer bottle 4, and a replacement core assembly.

[0031] The replacement core assembly includes an inner bottle 3, a bottom cover 1, a piston 2, a pump core 7, and a thread ring 6. The bottom cover 1 is snap-fitted to the bottom of the inner bottle; the piston 2 is installed in the inner bottle 3 with an interference fit; the thread ring 6 is snap-fitted outside the upper opening of the inner bottle 3; the lower part of the pump core 7 is inserted into the upper opening of the inner bottle 3, and the middle part of the pump core 7 is snap-fitted in the thread ring 6.

[0032] The replacement core assembly is detachably arranged in the outer bottle 4 through the shoulder sleeve assembly.

[0033] The shoulder sleeve assembly includes an outer shoulder sleeve 5, an inner shoulder sleeve 8, and a thread cap 9. The inner shoulder sleeve 8 is snap-fitted into the upper opening of the outer shoulder sleeve 5, and the thread cap 9 is snap-fitted into the inner shoulder sleeve 8.

[0034] The upper opening of the outer bottle 4 is snap-fitted into the lower opening of the outer shoulder sleeve 5; specifically, four screw-in slots 41 distributed at 90 degrees are provided on the outer wall of the upper opening of the outer bottle 4, and four shoulder sleeve ribs 51 distributed at 90 degrees are provided on the inner wall of the lower opening of the outer shoulder sleeve 5. The four shoulder sleeve ribs 51 are snap-fitted into the four screw-in slots 41 one by one.

[0035] The inner bottle 3 of the replacement core assembly is inserted into the outer bottle 4, and the thread cap 9 and the thread ring 6 are connected by screw threads. The lower end surface of the thread cap 9 and the upper end surface of the bottom plate of the thread ring 6 are respectively designed with mutually cooperating overshift card points 92 / overshift card points 61, so that when the two are screwed tightly to the end, there is a feeling of engaging in gear, and at the same time, it can prevent the problem of the inner bottle thread backing off caused by vibration during transportation, etc.

[0036] The inlet of the middle channel of the pressing cap 11 is inserted into the upper part of the pump core 7, and the lower end of the pressing cap 11 is inserted into the upper end opening of the inner shoulder sleeve 8. Specifically, a ring of pressing cap protrusions 111 is designed on the outer side of the lower end of the pressing cap 11, and the pressing cap protrusions 111 are in interference fit with the upper end opening of the inner shoulder sleeve 8, so that the pressing cap 11 cannot be ejected or pulled out after being pressed into the inner shoulder sleeve 8. A nozzle 12 is arranged at the outlet of the middle channel of the pressing cap 11.

[0037] The spring 10 is arranged between the pressing cap 11 and the threaded cap 9; a ring of spring fixing bosses 91 is arranged above the threaded cap 9, and the lower end of the spring 10 is sleeved on the spring fixing bosses 91. The upper end of the spring 10 is in contact with the pressing cap 11. The spring 10 can play a role in supporting and fixing the pressing cap 11 when the used replacement core assembly is screwed out.

[0038] The main product cover 13 covers the outside of the pressing cap 11.

[0039] The replacement core assembly further includes a replacement core cover 14. When the replacement core assembly is not installed in the outer bottle, the replacement core cover 14 covers the pump core 7, and the replacement core cover 14 is connected to the outer wall of the threaded ring 6 through thread fit.

[0040] For the replaceable vacuum packaging bottle of the present utility model, when the main product is used up and needs to be replaced, rotate the outer bottle 4 so that the four shoulder sleeve ribs 51 on the outer shoulder sleeve 5 are disengaged from the four screwing slots 41 one by one, remove the outer bottle 4, rotate the used replacement core assembly clockwise, disengage the threaded ring 6 of the replacement core assembly from the threaded cap 9 of the shoulder sleeve assembly, and disengage the inlet of the middle channel of the pressing cap 11 from the upper inner hole of the pump core 7, and remove the used replacement core assembly.

[0041] Then unscrew the replacement core cover 14 of the new replacement core assembly, insert the new replacement core assembly from the lower part of the outer shoulder sleeve 5, and rotate counterclockwise. The external thread of the threaded ring 6 of the new replacement core assembly is screwed tightly with the internal thread of the threaded cap 9 of the shoulder sleeve assembly. At the same time, the whole new replacement core assembly moves upward, pressing the pressing cap 11 upward. The pressing cap protrusions 111 on the outer side of the lower end of the pressing cap 11 effectively prevent the pressing cap from being ejected upward from the inner shoulder sleeve 8, so that the upper inner hole of the pump core 7 is in snap-fit connection with the inlet of the middle channel of the pressing cap. Finally, rotate the outer bottle 4 clockwise until the four shoulder sleeve ribs 51 on the outer shoulder sleeve 5 are snap-fitted into the four screwing slots 41 one by one for screwing fit, and complete the replacement of the whole replacement core.

[0042] In summary, for the replaceable vacuum packaging bottle of the present utility model, the situation that there are too few reusable parts in the existing replacement packaging materials is improved. The single replacement package is more concise and beautiful, has stronger process plasticity, and the replacement operation is simple and convenient. The separate replacement core is in a sealed vacuum state and the material will not be contaminated; this packaging material has stronger practicability, reduces waste, reduces environmental pollution, and better reflects the concept of environmental protection.
