[0006] The bottom end of the shoulder sleeve is clamped on the upper end of the outer bottle; the middle part of the pump core is clamped on the upper opening of the shoulder sleeve, and the push cap is connected to the upper end of the pump core by interference fit; the bottom end of the main product cover is clamped on the top end of the shoulder sleeve; the interior of the shoulder sleeve has a shoulder sleeve internal thread;

[0007] The replacement core assembly is detachably arranged in the outer bottle, and the external thread of the upper end opening of the inner bottle is tightened with the internal thread of the shoulder sleeve of the shoulder sleeve, the tail of the pump core is inserted into the inner plug, and the tail of the pump core is interference fit with the silicone plug inside the inner plug.

[0008] The above-mentioned replaceable double-layer vacuum packaging bottle, wherein the replaceable core assembly further comprises a replaceable core cover, and the replaceable core cover is threadedly connected to the external thread of the upper end opening of the inner bottle.

[0009] The above-mentioned replaceable double-layer vacuum packaging bottle, wherein, when replacing, the replacement core cover is unscrewed.

[0010] The replaceable double-layer vacuum packaging bottle of the utility model only needs to replace the replacement core packaging after the main product is used up, and the bottle can continue to be used; and the replacement core part does not include the pump core, so the cost of discarding the part is lower and more environmentally friendly; the replacement operation is simple and convenient, and the separate replacement core is not only in a sealed vacuum state that the material body will not be contaminated, but also during replacement, the material body will not be contaminated; this packaging material can reduce a large amount of plastic usage, reduce environmental pollution, and is more green and environmentally friendly.

[0012] Figure 2 It is a schematic diagram of the structure of the replacement core assembly;

[0013] Figure 3 It is a schematic diagram of the structure of the shoulder cover. DETAILED DESCRIPTION

[0014] In order to enable those skilled in the art to better understand the technical solution of the utility model, the specific implementation method thereof is described in detail below in conjunction with the accompanying drawings:

[0015] See also Figure 1 , Figure 2 and Figure 3 The best embodiment of the utility model is a replaceable double-layer vacuum packaging bottle, which is composed of a main product cover 1, a press cap 2, a shoulder sleeve 3, an outer bottle 4, a pump core 9 and a replacement core assembly, and the replacement core assembly is detachably arranged in the outer bottle 4.

[0016] The replacement core assembly includes an inner bottle 7, a bottom cover 5, a piston 6 and an inner plug 8; the bottom cover 5 is clamped on the bottom of the inner bottle 7, the piston 6 is installed on the inner wall of the inner bottle 7 with an interference fit, the inner plug 8 is clamped in the upper opening of the inner bottle 7, and the outer part of the upper opening of the inner bottle 7 is provided with an external thread 71; the interior of the inner plug 8 is provided with a one-way valve 81 and a silicone plug 82, and the one-way valve 81 is located below the silicone plug 82.

[0017] The bottom end of the shoulder sleeve 3 is clamped on the upper end of the outer bottle 4; the middle part of the pump core 9 is clamped on the upper opening of the shoulder sleeve 3, and the cap 2 is connected to the upper end of the pump core 9 by interference fit; the bottom end of the main product cover 1 is clamped on the top end of the shoulder sleeve 3; the interior of the shoulder sleeve 3 has a shoulder sleeve internal thread 31.

[0018] The replacement core assembly is detachably arranged in the outer bottle 4, and the outer thread 71 of the upper opening of the inner bottle 7 is screwed together with the inner thread 31 of the shoulder sleeve 3, the tail of the pump core 9 is inserted into the inner plug 8, and the tail of the pump core 9 is interference fit with the silicone plug 82 inside the inner plug 8. The replacement core part does not include the pump core, so that the discarded part is less expensive and more environmentally friendly.

[0019] The replacement core assembly also includes a replacement core cover 10, which is threadedly connected to the external thread 71 of the upper opening of the inner bottle 7. The replacement core cover 10 protects the material in the inner bottle 7 and isolates the pollution source. The replacement core assembly alone not only seals the vacuum state so that the material will not be polluted, but also prevents the material from being polluted when it is replaced.

[0020] When replacing, first unscrew the replacement core assembly originally placed in the outer bottle 4, then take out a new bottle of replacement core assembly, unscrew the replacement core cover 10, insert the replacement core into the outer bottle 4 from the bottom of the outer bottle 4, and rotate it clockwise. The external thread 71 of the upper end opening of the inner bottle 7 of the replacement core is tightened with the shoulder sleeve internal thread 31 of the shoulder sleeve 3, and the tail of the pump core 9 is interference fit with the silicone plug 82 inside the inner plug 8, and the replacement of the replacement core is completed.

[0021] In summary, the replaceable double-layer vacuum packaging bottle of the utility model improves the current situation of discarding vacuum packaging bottles after use. After the main product is used up, it only needs to replace the replacement core packaging to continue using it. And the replacement core part does not include the pump core, which makes the discarded part lower in cost and more environmentally friendly. The replacement operation is simple and convenient. The separate replacement core not only seals the vacuum state so that the material body will not be contaminated, but also the material body will not be contaminated when replaced. This packaging material can reduce a large amount of plastic usage, reduce environmental pollution, and is more green and environmentally friendly.
