[0002] A vacuum bottle is a container that isolates gas from external temperature or external bacteria. It works by using the contraction of a spring to create a vacuum, preventing air from entering the bottle, and then using atmospheric pressure to push a piston at the bottom of the bottle forward.

[0003] A prior art rotary dispensing vacuum bottle includes an outer bottle, an inner liner, a nozzle, and a rotating bottom cap. The nozzle protrudes from the outer bottle by rotating the bottom cap. This rotary dispensing vacuum bottle conceals the nozzle when not in use, preventing accidental dispensing during transport. It also prevents dust from adhering to the pump head surface, resulting in a more aesthetically pleasing and integrated design. It has been widely used in the cosmetics industry.

[0004] In the process of implementing the above-mentioned rotary liquid dispensing vacuum bottle, the inventors of this application discovered that the rotary liquid dispensing vacuum bottle has at least the following defects:

[0005] Once assembled, the inner liner of the aforementioned rotary vacuum bottle cannot be removed. After the contents are used up, the vacuum bottle cannot be reused, and the cost of purchasing it again is high. Discarding empty bottles also easily leads to a waste of resources.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0042] Please refer to the following for details. Figures 1-7 To address the problem of non-reusability of rotary vacuum bottles in related technologies, this invention provides a rotary replacement vacuum bottle, comprising a bottle body 1, an inner liner 2, a nozzle 3, a movable part 4, and a rotating part 5. The bottle body 1 is a hollow structure with openings at both ends. The inner liner 2 is detachably housed within the bottle body 1. The nozzle 3 is detachably mounted on the inner liner 2 via threads, and in its normal state, the nozzle 3 is partially concealed within the bottle body 1 to prevent accidental contact. The movable part 4 is positioned between the inner liner 2 and the rotating part 5, and is detachably connected to the inner liner 2. The rotating part 5 is rotatably mounted at the lower end of the bottle body 1, and its bottom inner surface has a protruding ejector portion 51 for ejecting and replacing the inner liner 2.

[0043] Based on the above technical means: when the contents of the inner liner 2 are used up, the inner liner 2 can be pushed out by the ejector part 51, so that the inner liner 2 can be replaced. This allows all parts except the inner liner 2 or the inner liner 2 and the nozzle 3 to be reused, which not only reduces the purchase cost for consumers, but also reduces the waste of resources.

[0044] A sealing element 6 is provided at the lower end of the inner liner 2. The diameter of the sealing element 6 is larger than the diameter of the inner liner 2. A first snap-fit ​​part 21 is provided on the inner wall of the lower end of the inner liner 2. A second snap-fit ​​part 61 is provided on the outer wall of the upper end of the sealing element 6. The second snap-fit ​​part 61 and the first snap-fit ​​part 21 form a snap-fit ​​engagement, so that the inner liner 2 and the sealing element 6 are fixed together.

[0045] The movable part 4 has four protruding limiting parts 41 inside. The sealing part 6 is located at the lower end of the limiting part 41 and is limited by the limiting part 41. When the inner liner 2 is assembled into the bottle body 1, the outer wall of the inner liner 2 will fit with the limiting part 41. With the limiting part 41 limiting the sealing part 6, the inner liner 2, the sealing part 6 and the movable part 4 are fixed together. In this way, when the movable part 4 moves, the inner liner 2 can also move with it.

[0046] The top surface of the limiting part 41 is a slope, which facilitates the insertion of the sealing element 6 into the bottom of the limiting part 41.

[0047] The movable part 4 has a through hole 42, and the ejector part 51 is inserted into the through hole 42 and is opposite to the sealing part 6.

[0048] One end of the rotating member 5 is provided with a force-applying part 52, which is connected to the rotating member 5 only through a narrow connecting part 53. The ejector part 51 is provided on the force-applying part 52. In this way, when force is applied to the force-applying part 52, the connecting part 53 will deform, allowing the force-applying part 52 to move towards the inner liner 2. This causes the ejector part 51 to gradually approach the sealing member 6, apply pressure to the sealing member 6, and eject the sealing member 6 and the inner liner 2 from the movable member 4, making it easy to remove and replace the inner liner 2. Due to the design of the connecting part, the force-applying part 52 will not fall off the rotating member 5, allowing the force-applying part 52 and the ejector part 51 to work repeatedly.

[0049] The inner wall of the rotating part 5 has two opposing track grooves 54, and the outer wall of the movable part 4 has two opposing locking points 43. The locking points 43 are used in conjunction with the track grooves 54, and the locking points 43 can move in the track grooves 54.

[0050] The top of the track groove 54 has an opening. The locking point 43 is inserted into the track groove 54 through the opening. Rotating the rotating part 5 will cause the movable part 4 to rise and fall in the rotating part 5, which will drive the inner liner 2 and the nozzle 3 to rise and fall, so that the nozzle 3 is hidden in the bottle body 1 or emerges from the bottle body 1.

[0051] Two opposing guide parts 11 are provided on the inner wall of one end of the bottle body 1, and two opposing guide grooves 44 are provided on the movable part 4. The guide grooves 44 and the guide parts 11 work together to play a guiding role.

[0052] The guide groove 44 does not penetrate the bottom surface of the movable part 4. When the movable part 4 rises to the highest point, the guide part 11 will come into contact with the bottom surface of the movable part 4, preventing the movable part 4 from rising further. In other words, the guide part 11 also serves to limit the stroke.

[0053] One end of the bottle body 1 is provided with a first mating part 12, and one end of the rotating part 5 is provided with a second mating part 55. The second mating part 55 is used in conjunction with the first mating part 12. The rotating part 5 is connected to the bottle body 1 through the cooperation of the second mating part 55 and the first mating part 12, and can rotate around the central axis of the bottle body 1.

[0054] A stop 13 is provided at one end of the bottle body 1. When the inner liner 2 and the nozzle 3 retract, the nozzle 3 will abut against the stop 13, which will serve as a limit.

[0055] The top cover of nozzle 3 has a transitional arc design. Specifically, the arc of the top cover at the nozzle gradually increases towards the other end, which is more comfortable to hold.

[0056] The bottle body 1, inner liner 2, moving parts 4, and rotating parts 5 are all made of PP material, which is more environmentally friendly.

[0057] This utility model relates to a rotary replacement vacuum bottle, and its working principle is explained in conjunction with the accompanying drawings:

[0058] Instructions for use: When you need to take the contents of the inner liner 2, simply rotate the rotating part 5. The movable part 4 will slowly rise under the action of the locking point 43 and the track groove 54, which will in turn drive the inner liner 2, the sealing part 6 and the nozzle 3 to rise, so that the nozzle 3 emerges from the bottle body 1, making it easy for the user to press the nozzle 3 for use. When you do not need to take the contents, simply rotate the rotating part 5 in the opposite direction. The movable part 4 will slowly descend under the action of the locking point 43 and the track groove 54, which will in turn drive the inner liner 2, the sealing part 6 and the nozzle 3 to retract, so that the nozzle 3 is hidden in the bottle body 1, which can prevent accidental contact.

[0059] Replacement method: When the contents of the inner liner 2 are used up, simply press the force application part 52 to move the ejector part 51 toward the seal 6. Since the limiting part 41 does not restrict the inner liner 2 and the seal 6 much, the seal 6 and the inner liner 2 can be easily ejected by the ejector part 51 and separated from the limiting part 41. At this time, the inner liner 2, the seal 6 and the nozzle 3 can be removed from the bottle body 1. Then replace the inner liner 2 and the seal 6 or the inner liner 2, the seal 6 and the nozzle 3. Then put the new parts back into the bottle body 1 and press down so that the seal 6 is inserted into the lower part of the limiting part 41, thus completing the replacement of the inner liner 2.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
