Description

Technical Field

[0001] The utility model relates to a cosmetic bottle structure, more specifically, it relates to an inner plug structure of a cosmetic bottle. Background Art

[0002] The inner plug structure of a cosmetic bottle generally refers to the parts inside the cosmetic bottle that are used to seal and fix the product. Specifically, it may include one or more components that work together to ensure the sealing, stability and ease of use of the product.

[0003] After using the cosmetic bottle with the inner plug structure, the cosmetics in the cosmetic bottle will adhere to the bottle wall. The cosmetics contain various chemical media, such as solvents, grease, etc. When these chemical media come into contact with the inner plug made of rubber material, chemical reactions are likely to occur, causing changes in the physical and chemical properties of the rubber, such as hardening and brittleness, thereby affecting its sealing performance.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an inner plug structure for a cosmetic bottle, which enters into the cosmetic bottle and contacts the bottle wall through an annular scraper. During the process of inserting the annular scraper into the bottle, the cosmetic residues attached to the bottle wall are scraped off to prevent the cosmetic residues from adhering to the rubber inner plug and reacting chemically with it, thereby reducing the sealing performance of the rubber inner plug. The contact between the annular scraper and the bottle wall can flatten the uneven parts on the bottle wall, such as tiny protrusions or depressions. This helps to ensure that the contact between the rubber inner plug and the bottle wall is more uniform and tight, thereby improving the sealing performance. The rubber inner plug has a certain elasticity and compressibility. When the positioning extrusion block applies pressure, the rubber inner plug will be compressed, so that its sealing surface fits the bottle mouth better. This improved fit improves the sealing performance of the rubber inner plug to the cosmetic bottle.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: an inner plug structure of a cosmetic bottle, comprising a bottle body and a rubber inner plug, the upper end of the bottle body is fixedly installed with a bottle mouth, the upper end of the rubber inner plug is fixedly installed with a threaded plug body, the threaded plug body and the rubber inner plug are communicated, the interior of the threaded plug body is movably connected with a positioning extrusion block, the upper end of the threaded plug body is fixedly installed with a sealing top, the lower end of the rubber inner plug is fixedly installed with an annular scraper, and the diameter of the annular scraper is the same as the diameter of the rubber inner plug.

[0007] The utility model is further configured as follows: the inner diameter of the bottle mouth is the same as the diameter of the rubber inner plug.

[0008] The utility model is further configured as follows: a screw rod is fixedly installed on the upper end of the positioning extrusion block, and a knob is fixedly installed on the upper end of the screw rod.

[0009] The utility model is further configured such that: the axis center lines of the bottle mouth and the rubber inner plug coincide with each other.

[0010] In summary, the utility model has the following beneficial effects:

[0011] 1. The annular scraper enters the cosmetic bottle and contacts the bottle wall. During the insertion process, the annular scraper will scrape off the cosmetic residues attached to the bottle wall to prevent the cosmetic residues from adhering to the rubber inner plug and reacting chemically with it, which will affect the reduction of the sealing performance of the rubber inner plug. The contact between the annular scraper and the bottle wall can flatten the uneven parts on the bottle wall, such as tiny bumps or depressions. This helps to ensure that the contact between the rubber inner plug and the bottle wall is more uniform and tight, thereby improving the sealing performance. The rubber inner plug has a certain elasticity and compressibility. When the positioning extrusion block applies pressure, the rubber inner plug will be compressed, so that its sealing surface fits the bottle mouth better. This improved fit improves the sealing performance of the rubber inner plug to the cosmetic bottle. BRIEF DESCRIPTION OF THE DRAWINGS

The diameters of the inner plugs 2 are the same. An annular scraper 7 is provided below the rubber inner plug 2. When the rubber inner plug 2 is inserted into the cosmetic bottle, the annular scraper 7 is driven to enter the cosmetic bottle and contact the bottle wall. During the insertion process, the annular scraper 7 will scrape off the cosmetic residues attached to the bottle wall to prevent the cosmetic residues from adhering to the rubber inner plug 2 and reacting chemically with it to reduce the sealing performance of the rubber inner plug 2. The contact between the annular scraper 7 and the bottle wall can flatten the uneven parts on the bottle wall, such as tiny protrusions or depressions. This helps to ensure that the contact between the rubber inner plug 2 and the bottle wall is more uniform and tight, thereby improving the sealing performance. When the positioning extrusion block 5 moves downward, it enters the rubber inner plug 2 and contacts the inner wall of the rubber inner plug 2. The rubber inner plug 2 has a certain elasticity and compressibility. When the positioning extrusion block 5 applies pressure, the rubber inner plug 2 will be compressed, so that its sealing surface better fits the bottle mouth 3. This improved fit improves the sealing performance of the rubber inner plug 2 to the cosmetic bottle.

[0021] A screw rod 8 is fixedly installed on the upper end of the positioning extrusion block 5, and a knob 9 is fixedly installed on the upper end of the screw rod 8. By turning the knob 9, the screw rod 8 is driven to rotate, and the positioning extrusion block 5 in the threaded plug body 4 is driven to move downward and enter the rubber inner plug 2.

[0022] Working principle: An annular scraper 7 is arranged below the rubber inner plug 2. When the rubber inner plug 2 is inserted into the cosmetic bottle, the annular scraper 7 is driven to enter the cosmetic bottle and contact the bottle wall. During the insertion process, the annular scraper 7 will scrape off the cosmetic residues attached to the bottle wall to prevent the cosmetic residues from adhering to the rubber inner plug 2 and reacting chemically with it to reduce the sealing performance of the rubber inner plug 2. The contact between the annular scraper 7 and the bottle wall can flatten the uneven parts on the bottle wall, such as tiny protrusions or depressions. This helps to ensure that the contact between the rubber inner plug 2 and the bottle wall is more uniform and tight, thereby improving the sealing performance. By turning the knob 9 to drive the screw rod 8 to rotate, the positioning extrusion block 5 in the threaded plug body 4 is driven to move downward and enter the rubber inner plug 2, and contact the inner wall of the rubber inner plug 2. The rubber inner plug 2 has a certain elasticity and compressibility. When the positioning extrusion block 5 applies pressure, the rubber inner plug 2 will be compressed, so that its sealing surface fits the bottle mouth 3 better. This improved fit improves the sealing performance of the rubber inner plug 2 to the cosmetic bottle.
