[0016] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] like Figures 1 to 4As shown, an airtight rotary packaging bottle includes a bottle body 1, a bottle cap 2, an inner cap 3 and a telescopic member 4. The telescopic member 4 is detachably connected to the bottle mouth of the bottle body 1. A sealing head 41 is provided in the middle of the telescopic member 4. The inner cap 3 is movably sleeved on the outer periphery of the telescopic member 4. The bottle cap 2 is sleeved on the outside of the inner cap 3. A discharge pipe 31 is provided in the middle of the inner cap 3. The discharge pipe 31 passes through the through hole 21 on the bottle cap 2. The discharge pipe 31 is connected to the bottle body 1 through the telescopic member 4. The inner cap 3 is displaced along the axial direction of the telescopic member 4, so that the sealing head 41 movably blocks the discharge pipe 31. Specifically, in this embodiment, the telescopic member 4 is detachably assembled at the bottle mouth of the bottle body 1, and the telescopic member 4 is cylindrical and can serve as a conduit for the flow of fluid in the bottle body 1. The inner cap 3 is spirally sleeved on the outside of the telescopic member 4. When the inner cap 3 rotates, it can be displaced along the axial direction of the telescopic member 4, thereby driving the discharge pipe 31 at the top of the inner cap 3 to move up and down. When the discharge pipe 31 descends, because the position of the telescopic member 4 remains stationary, the sealing head 41 in the middle of the telescopic member 4 can block the discharge pipe 31, thereby preventing the fluid from flowing out of the discharge pipe 31. It is understandable that the sealing head 41 in the middle of the telescopic member 4 will not block the flow of fluid. The telescopic member 4 has a hollow space in the middle to facilitate the outflow of fluid. For the sake of aesthetics and to prevent the discharge pipe 31 of the inner cap 3 from being contaminated, we have a bottle cap 2 installed on the outer cover of the inner cap 3. The bottle cap 2 and the inner cap 3 adopt a snap-on design. When the bottle cap 2 is screwed, the inner cap 3 can be driven to rotate synchronously. A through hole 21 is provided on the end surface of the bottle cap 2 so that the discharge pipe 31 can extend out of the through hole 21 to avoid blocking the outflow of fluid.

[0020] like Figures 2-4 As shown, the inner wall of the orifice of the discharge pipe 31 is tapered, and the top of the sealing head 41 is designed to be tapered to correspond to the tapered opening. Specifically, during sealing, the tapered head at the top of the sealing head 41 fits into the orifice of the discharge pipe 31. This tapered fit provides a wider contact area, stronger airtightness, and facilitates insertion of the sealing head 41 into the discharge pipe 31 without misalignment.

[0021] like Figures 2-4 As shown, the outer wall of the telescopic member 4 is provided with a spiral groove 42 along the circumferential direction, and the inner wall of the inner cover 3 is provided with a protrusion 32 , and the protrusion 32 is movably engaged in the spiral groove 42 .

[0022] like Figures 2-3 As shown, the outer wall of the telescopic member 4 is further provided with a slideway 43 along the axial direction, and the slideway 43 is connected to the end of the spiral groove 42. Specifically, during assembly, the user aligns the protrusion 32 with the slideway 43 and then presses down the inner cover 3, so that the protrusion 32 enters the spiral groove 42, and then the inner cover 3 can rotate and rise and fall along the spiral groove 42, which facilitates production and assembly.

[0023] like Figures 2-3 As shown, the bottle mouth of the bottle body 1 is provided with a heat sealing sheet 5, and the heat sealing sheet 5 is used to seal the bottle body 1 before leaving the factory to prevent the volatilization and leakage of the fluid, and to enhance the airtightness.

[0024] like Figures 2-4 As shown, the outer periphery of the bottle mouth of the bottle body 1 is provided with an external thread, and the inner wall of the telescopic member 4 is provided with an internal thread. The telescopic member 4 is detachably connected to the bottle mouth of the bottle body 1 via the threaded structure. Specifically, during assembly, the telescopic member 4 only needs to be screwed directly onto the bottle body 1, which is simple to operate and can also ensure unobstructed connectivity between the bottle body 1 and the telescopic member 4.

[0025] like Figures 2-3 As shown, the outer wall of the inner cover 3 is provided with a vertical bar 33, and the inner wall of the bottle cap 2 is provided with a card slot 22 corresponding to the vertical bar 33. Specifically, after the bottle cap 2 is put on the inner cover 3, in order to avoid screwing the inner cover 3 after removing the bottle cap 2, we use the vertical bar 33 to engage with the card slot 22. When the bottle cap 2 is not removed, screwing the bottle cap 2 can also drive the inner cover 3 to rotate, thereby causing the discharge pipe 31 to rise and fall, and flexibly cooperate with the sealing head 41, so as to facilitate the pouring of the fluid, which is extremely convenient to use.

[0026] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
