[0030] The specific assembly method of the vacuum bottle is as follows: for the nozzle assembly, first install the pump core assembly from the bottom of the large circle, the buckle position of the small inner plug of the pump core assembly and the buckle position of the center hole of the large circle are interference fit, then install the gasket from the bottom of the large circle into the outer diameter of the interference pump body and assemble it into place, press the head cap into the valve stem from the top of the pump core assembly, the buckle position of the head cap and the buckle position of the valve stem of the pump core assembly are buckled and sealed; finally, install the inner suction tube from the bottom of the pump core assembly, the sealing surface of the inner suction tube and the sealing surface of the pump body of the pump core assembly are interference sealed, and the assembly of the nozzle assembly is completed. To assemble the middle ring, first install the inner chamber from the bottom of the middle ring. The sealing ring of the inner chamber and the sealing surface of the inner liquid cavity of the middle ring are in interference sealing fit. The inner ribs of the inner chamber and the outer wall of the inner liquid cavity of the middle ring are in interference fit, which plays an interference role and improves the hand feel during rotation by increasing friction. The spiral groove (beveled slide groove) of the inner chamber and the spiral edge (beveled slide rib) of the middle ring are fixed and stopped; then install the large inner plug from the bottom of the inner chamber, the guide ribs of the large inner plug and the guide groove of the inner plug are fixed and vertically slid, and the ring rib groove of the large inner plug and the inner ring rib buckle position of the middle ring are sealed (rotatable), and the assembly of the middle ring is completed. To assemble the bottle body, first install the piston from the top of the bottle body, the piston and the bottle body are in interference sealing fit, and the bottle body is assembled after being pressed into place.
[0031] The filling and assembly steps of the vacuum bottle are as follows: first, the first liquid is poured into the bottle body assembly, the middle ring is aligned with the bottle body and pressed down, the inner buckle groove of the middle ring is matched with the outer diameter of the bottle mouth of the bottle body (rotatable), the sealing ring of the inner plug is matched with the inner diameter of the bottle mouth of the bottle body in an interference sealing manner, and the buckle block of the large inner plug is fixedly matched with the notch at the bottle mouth of the bottle body; then the second liquid is poured into the middle ring assembly, the nozzle assembly is screwed in from the top of the middle ring assembly, the inner thread of the nozzle assembly is screwed into the outer thread of the middle ring assembly to the bottom, and the gasket is matched with the ring mouth of the middle ring in an interference sealing manner; finally, the outer cover is pressed in from the top of the nozzle assembly, the outer cover and the large ring are matched in place, and the product assembly is completed when they are pressed in place.
[0032] The replacement assembly of the vacuum bottle can be assembled into another bottle body and a replacement cap to become a replacement package. After the regular package is used up, the nozzle assembly can be unscrewed and replaced with the replacement assembly to continue using it. The function of the replacement assembly remains unchanged.
[0033] When in use, rotating the middle circle drives the inner bin to rotate downward, so that the inner bin is separated from the middle circle, and the liquid in the middle circle flows out and mixes with the liquid in the bottle body, and the vacuum bottle can be used normally.
[0034] The functional principle of the vacuum bottle is as follows: rotate the middle circle 160° counterclockwise, that is, when it turns to the maximum angle, the fixed block of the middle circle and the limit block of the bottle body stop rotating and positioning, the inclined sliding ribs in the middle circle push the inclined sliding groove of the inner bin to rotate, and the inner bin moves downward under the positioning and orientation of the guide ribs of the large inner plug, so that the inner bin is separated from the bottom of the middle circle, and the first liquid in the middle circle flows out from the two hollow holes of the inner bin and mixes with the second liquid in the bottle body. After shaking the vacuum bottle, the double materials are mixed. After the mixture is evenly mixed, the head cap is pressed normally to discharge the liquid, and the normal use function of the vacuum bottle can be realized. The movement of the inner bin in the vacuum bottle is one-time, and the inner bin cannot be raised by inverting.
[0035] In summary, the vacuum bottle is a mechanically rotating opening double-liquid mixing vacuum bottle with a replaceable assembly. The vacuum bottle is used to separately fill, isolate and seal two liquids in cosmetic packaging materials in one container, and uses rotation to achieve double-liquid mixing between the liquid in the bottle body and the liquid in the inner liquid cavity of the middle ring.
