[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the specific implementation methods are described in detail below with reference to the accompanying drawings:

[0030] See also Figures 1 to 8 The best embodiment of the present invention is a replaceable vacuum packaging bottle, comprising a main product cover 12, a press cap 11, a spring 10, an outer shoulder sleeve 8, an inner shoulder sleeve 9, an outer bottle 7 and a replaceable core assembly.

[0031] The replacement core assembly includes an inner bottle 3, a bottom cover 1, a piston 2, a pump core 5 and a threaded cover 6. The bottom cover 1 is clamped on the bottom of the inner bottle 3; the piston 2 is installed in the inner bottle 3 with an interference fit; the threaded cover 6 is clamped on the outside of the upper opening of the inner bottle 3; the lower part of the pump core 5 is inserted into the upper opening of the inner bottle 3, and the middle part of the pump core 5 is clamped in the threaded cover 6, and a gasket 4 is provided between the pump core 5 and the top surface of the upper opening of the inner bottle 3.

[0032] The inner shoulder sleeve 9 is interference fit and clamped in the outer shoulder sleeve 8; the upper end opening of the outer bottle 7 is clamped in the lower end opening of the outer shoulder sleeve 8; specifically, the inner wall of the upper end opening of the outer bottle 7 is provided with two screw-in grooves 71 distributed at 180 degrees, and the outer wall of the lower end opening of the outer shoulder sleeve 8 is provided with two shoulder sleeve ribs 81 distributed at 180 degrees, and the two shoulder sleeve ribs 81 are clamped in the two screw-in grooves 71 one by one.

[0033] The inner bottle 3 of the replacement core assembly is inserted into the outer bottle 7, and the threaded cover 6 is threadedly connected to the inner shoulder sleeve 9; the interior of the inner shoulder sleeve 9 is provided with an internal thread 91, which cooperates with the external thread 61 of the threaded cover 6 of the replacement core assembly, and the tightening ends of the two threads are provided with mutually cooperating shifting points, so that the thread has a gear-entering feel after being tightened into place, and at the same time, it can prevent the problem of the inner bottle thread retreating caused by vibration transportation.

[0034] The inlet of the middle channel of the pressing cap 11 is inserted into the upper part of the pump core 5, and the lower end of the pressing cap 11 is inserted into the upper opening of the inner shoulder sleeve 9; a circle of pressing cap protrusions is designed on the outer side of the lower end of the pressing cap 11, and the pressing cap protrusions form an interference structure with the upper opening of the outer shoulder sleeve 8, so that the pressing cap 11 cannot be pushed out or pulled out after being pressed into the inner shoulder sleeve 9.

[0035] The spring 10 is arranged between the push cap 11 and the inner shoulder sleeve 9; a circle of spring fixing bosses 92 is provided in the inner shoulder sleeve 9 to facilitate fixing the spring. The lower end of the spring 10 is sleeved on the spring fixing boss 92, and the push cap 11 and the inner shoulder sleeve 9 are connected and supported by the spring 10; the spring 10 can support and fix the push cap 11 when the replacement core assembly is screwed out.

[0036] The main product cover 12 covers the outside of the push cap 11 , and the lower end of the main product cover 12 is clamped on the outside of the outer shoulder sleeve 8 .

[0037] The replacement core assembly further includes a replacement core cover 13 . When the replacement core assembly is not installed in the outer bottle 7 , the replacement core cover 13 covers the pump core 5 , and the lower end of the replacement core cover 13 is clamped on the outer wall of the threaded cap 6 .

[0038] The replaceable vacuum packaging bottle of the present invention is designed to be replaced when the main product is used up and needs to be replaced by rotating the outer bottle 7 so that the two shoulder sleeve ribs 81 on the outer shoulder sleeve 8 are disengaged from the two screw-in slots 71 one by one, and then the outer bottle 7 is removed. The used replacement core assembly is rotated clockwise to disengage the threaded cover 6 of the replacement core assembly from the inner shoulder sleeve 9, and the inlet of the middle channel of the press cap 11 is disengaged from the upper inner hole of the pump core 5, and then the used replacement core assembly is removed.

[0039] Then unscrew the replacement core cover 13 of the new replacement core assembly, insert the new replacement core assembly into the interior from the lower end of the inner shoulder sleeve, rotate it counterclockwise, and the external thread 61 of the threaded cover 6 of the new replacement core assembly is tightened with the internal thread 91 of the inner shoulder sleeve 9. At the same time, the entire replacement core assembly moves upward, pressing the push cap 11 upward. The push cap protrusion on the outer side of the lower end of the push cap 11 effectively prevents the push cap 11 from being pushed out upward, so that the inner hole of the mouth of the pump core 5 is engaged with the middle channel inlet of the push cap 11. Finally, rotate the outer bottle 7 until the two shoulder sleeve ribs 81 on the outer shoulder sleeve 8 are screwed into the two screw-in slots 71 of the outer bottle 7 one by one, completing the entire replacement core replacement.

[0040] To sum up, the replaceable vacuum packaging bottle of the present invention improves the situation that the existing replacement packaging materials have too few reusable parts. The single replacement package is more simple and beautiful, the process plasticity is stronger, and the replacement operation is simple and convenient. The separate replacement core is in a sealed vacuum state and the material body will not be contaminated. This packaging material is more practical, reduces waste, reduces environmental pollution, and better embodies the concept of environmental protection.

[0041] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
