Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: a cosmetic packaging bottle with a quantitative liquid dispensing structure, including a bottle body 1, a bottle cap 2 detachably installed at the top of the bottle body 1, a through opening vertically through the middle of the upper surface of the bottle cap 2, and a connecting cylinder 3 with an open top and an inner diameter adapted to the through opening is vertically fixedly connected to the lower surface of the bottle cap 2.

[0020] The upper part of the inner cavity of the connecting cylinder 3 is provided with an internal thread 4. The inside of the connecting cylinder 3 is threadedly connected to a threaded post 5 through the internal thread 4. The bottom end of the threaded post 5 is vertically fixedly connected to a limit post 6. The top end of the threaded post 5 is vertically opened with a sliding hole that extends to the bottom end of the limit post 6. A sliding rod 7 is vertically slidably connected inside the sliding hole. A piston block 9 is provided at the bottom end of the sliding rod 7 and below the limit post 6. Both sides of the bottom end of the connecting cylinder 3 are connected to a connecting pipe 10. The bottom ends of the two connecting pipes 10 are respectively connected to a liquid suction hose 11 and a liquid discharge hose 12.

[0021] The bottom end of the slide rod 7 is rotatably connected to the connecting plate 8, and the piston block 9 is fixedly connected to the bottom end of the connecting plate 8. The outer surface of the piston block 9 is interference-fitted with the inner surface of the connecting cylinder 3.

[0022] In this embodiment, when the device is in use, rotating the threaded column 5 will cause it to move along the length of the connecting cylinder 3 under the action of the internal thread 4, and simultaneously drive the limiting column 6 to move. This changes the distance between the bottom end of the limiting column 6 and the bottom end of the connecting cylinder 3, thereby changing the movement distance of the piston block 9 at the bottom end of the slide rod 7. By changing this distance, the amount of cosmetic liquid drawn and squeezed out each time through the piston block 9 can be changed, thus achieving a quantitative function.

[0023] Since the slide rod 7 is slidably connected inside the sliding hole of the threaded column 5 and the limiting column 6, the slide rod 7 will not move vertically synchronously when the threaded column 5 is rotated. When it is necessary to squeeze out the cosmetic liquid, the slide rod 7 is pulled upward to drive the piston block 9 at its bottom to move upward synchronously until its top end contacts the bottom end of the limiting column 6 and can no longer move upward. During this process, a negative pressure is generated inside the connecting cylinder 3, and the cosmetic liquid inside the bottle 1 will enter the interior of the connecting cylinder 3 through the liquid extraction hose 11. Then, the slide rod 7 is pressed down to drive the piston block 9 to move downward synchronously. Under the action of pressure, the cosmetic liquid inside the connecting cylinder 3 will be discharged through the liquid discharge hose 12.

[0024] Furthermore, each of the two connecting pipes 10 is equipped with a one-way valve 13, and the two one-way valves 13 are arranged in opposite directions.

[0025] In this embodiment, the one-way valve 13 is used to restrict the liquid extraction hose 11 and the liquid discharge hose 12, so that they can only perform liquid extraction and liquid discharge operations.

[0026] Furthermore, the other end of the drain hose 12 extends upward and penetrates the upper surface of the bottle cap 2. The top end of the drain hose 12, located above the bottle cap 2, is connected to the outlet pipe 14, which is fixedly connected to the upper surface of the bottle cap 2.

[0027] In this embodiment, the cosmetic liquid discharged through the drainage hose 12 will eventually be discharged through the outlet pipe 14.

[0028] Furthermore, a pressure plate 15 is fixedly connected to the top of the slide bar 7.

[0029] In this embodiment, the pressure plate 15 facilitates people to pull up and press the slide bar 7.

[0030] Furthermore, a limiting ring 16 with an outer diameter larger than the inner diameter of the connecting cylinder 3 is fixedly connected to the outer surface of the threaded column 5 and located above the bottle cap 2. Both the limiting ring 16 and the outer surface of the bottle cap 2 are provided with anti-slip texture.

[0031] In this embodiment, the limiting ring 16 serves as a limiting element to prevent the threaded post 5 from completely entering the interior of the connecting cylinder 3 and being unable to unscrew outwards, while the multiple anti-slip patterns provide an anti-slip effect, making it convenient for people to use.

[0032] The working principle and usage process of this utility model: After the utility model is installed, when the device is in use, rotating the threaded column 5 will cause it to move along the length of the connecting cylinder 3 under the action of the internal thread 4, and simultaneously drive the limiting column 6 to move. This changes the distance between the bottom end of the limiting column 6 and the bottom end of the connecting cylinder 3, thereby changing the movement distance of the piston block 9 at the bottom end of the slide rod 7. By changing this distance, the amount of cosmetic liquid extracted and squeezed out each time through the piston block 9 can be changed, thus achieving the quantitative function.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
