[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] Example:

[0027] like Figure 1-4 As shown, a novel cosmetic bottle cap for preventing secondary pollution comprises a dropper and a cover body 2, wherein the dropper passes vertically through and is installed on the cover body 2, the cover body 2 is provided with a corresponding bottle body 5, an anti-fouling part 8 and an elastic member 6 are provided on the inner side of the cover body 2, a middle hole 12 for the dropper to pass through is opened in the middle of the anti-fouling part 8, the outer side of the anti-fouling part 8 is fitted and sealed with the inner wall of the cover body 2, and the elastic member 6 is suitable for abutting the anti-fouling part 8 so that it is located at the inner bottom of the cover body 2. In this way, each time the cover is used, the anti-fouling part 8 can automatically move to the bottom of the inner cavity of the cover body 2 after the cover is opened, so as to prevent liquid from entering the inside of the cover body 2 during use, thereby contaminating the cover body 2, and further preventing the cover body 2 from causing secondary pollution to the liquid in the bottle body 5 after the cover body 2 is covered with the bottle body 5.

[0028] After the cover 2 is installed to the cosmetic bottle 5, the anti-fouling part 8 is abutted by the top of the bottle 5 and moves upward. After the cover 2 is installed, the position of the anti-fouling part 8 corresponding to the dropper is the first position, and the dropper is formed with a recess 13 at the first position. When the cover 2 is moved out, the elastic member 6 is reset to allow the anti-fouling part 8 to scrape off the liquid contaminated on the inner wall of the cover 2 and block the inner bottom of the cover 2 at the same time; obviously, some liquid sometimes enters the cover 2 due to the overall movement of the cosmetic bottle 5. If these liquids are not handled in time, they will remain in the cover 2. The traditional cover 2 will adhere to the top of the inner cavity of the cover 2 and dry up to form crystals. If this part is not paid attention to during use, it may fall into the cosmetic bottle 5, thereby causing pollution. In this embodiment, through the setting of the elastic member 6, when the cover 2 is opened and closed, the anti-fouling part 8 will scrape the inner wall of the cover 2 back and forth, and the anti-fouling part 8 itself can prevent the liquid from entering the top of the cover 2, so it can effectively reduce the adhesion and drying of the liquid in the cover 2.

[0029] Preferably, the elastic member 6 is a spring.

[0030] like Figure 3 As shown, the length of the cover body 2 is greater than the length of the bottle mouth 9, so that there is a gap between the top inner wall of the cover body 2 and the bottle mouth 9 when the cover body 2 is buckled. At the same time, the anti-fouling part 8 is elastically abutted against the top of the bottle mouth 9 by the elastic member 6 to make the bottle mouth 9 sealed.

[0031] Two specific embodiments of optimizing the dropper near the recess 13 are proposed below:

[0032] (1) The initial outer diameter of the recess 13 is larger than the diameter of the middle hole 12. The diameter of the dropper is the same except that the diameter of the recess 13 is reduced. When the cover 2 is removed, the elastic member 6 moves the anti-fouling portion 8 downward. At this time, the middle hole 12 acts on the outer wall of the dropper to compress the wall of the dropper at the acting position, so that the liquid in the dropper is automatically emptied each time the cover is opened. After use, the anti-fouling portion 8 is pressed to move the anti-fouling portion 8 upward and pass through the position of the recess 13, so that the wall of the dropper is compressed, thereby emptying the liquid remaining in the dropper after use.

[0033] (2) The initial outer diameter of the recess 13 is equal to or greater than the diameter of the middle hole 12, and the diameters of the tube walls of the dropper on both sides of the recess 13 decrease and increase in sequence. When the cover 2 is removed, the elastic member 6 causes the anti-fouling portion 8 to move downward, and at this time the middle hole 12 acts on the outer wall of the dropper to compress the tube wall of the dropper at the acting position, so that the liquid in the dropper is automatically emptied each time the cover is opened; after use, the anti-fouling portion 8 is pressed to move the anti-fouling portion 8 upward and pass through the position of the recess 13, so that the tube wall of the dropper is compressed, thereby emptying the liquid remaining in the dropper after use.

[0034] Both of the above embodiments can realize automatic removal of the liquid in the dropper when the cover is opened, so that the user can freely take a quantitative cosmetic; and after use, the user can selectively press the anti-fouling part 8 to move upward as needed to empty the residual liquid in the dropper to prevent this part of the liquid from returning to the bottle body 5 with the dropper to cause secondary contamination.

[0035] like Figure 4 As shown, the bottom inner wall of the cover body 2 is provided with a thread groove 15, and the outer wall of the bottle mouth 9 is provided with an external thread that matches the thread groove 15. The cover body 2 is fixed to the bottle mouth 9 by rotating the thread.

[0036] To ensure good sealing between the anti-fouling part 8 and the cover 2 when they move relative to each other, a sealing gasket 7 is fixedly installed at the junction of the anti-fouling part 8 and the inner wall of the cover 2. The sealing gasket 7 moves with the anti-fouling part 8 and maintains the sealing between the anti-fouling part 8 and the inner wall of the cover 2.

[0037] In order to facilitate opening or closing of the cover body 2, the outer surface of the cover body 2 is provided with anti-slip grooves, and the direction of the anti-slip grooves is in the vertical direction.

[0038] like Figure 3 As shown, the bottle body 5 includes an inner liner 10, the top and bottom of the inner liner 10 are fixedly connected to the bottom of the bottle mouth 9 and the bottom wall of the bottle body 5 respectively; under the protection of the bottle body 5, the inner liner 10 is safer and more stable for containing cosmetic liquid.

[0039] The dropper comprises a first tube body 3 and a second tube body 11. The diameter of the second tube body 11 is smaller than that of the first tube body 3. A scale is provided on the surface of the second tube body 11. Since the diameter of the second tube body 11 is small, better accuracy is achieved when marking the scale.

[0040] The dropper includes a liquid taking head 1, which can be an existing Figure 3 The rubber pressing head 1a shown in the figure can also be Figure 4 As shown, a limit piece 14 is provided on the top of the cover body 2, and a knob head 1b is provided on the inner thread of the limit piece 14. A sealing rubber pad should be provided at the bottom edge of the knob head 1b to ensure the sealing performance. The knob head 1b is adjusted up and down by rotating it. The knob head 1b, the limit piece 14 and the dropper are connected to form a liquid channel. When the knob head 1b is adjusted up and down, the volume of the above-mentioned liquid channel is adjusted. After the knob head 1b is lowered, it is inserted into the bottle body 5 containing cosmetics, and then the knob head 1b is raised. During the process, the liquid outlet 4 at the bottom of the dropper is located below the liquid surface of the cosmetics, and liquid collection can be completed. The advantage of liquid collection in this way is that the amount of liquid collected is easy to control, but the use and operation of the rubber liquid collection head 11a is more troublesome, and it can be selected according to needs.

[0041] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
