DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 , a highly sealed and highly elastic silicone plug in this embodiment includes a silicone plug body 1. A plug cover 2 is fixed on the upper surface of the silicone plug body 1. By providing the plug cover 2 on the upper surface of the silicone plug body 1, the plug cover 2 can prevent the silicone plug body 1 from completely entering the bottle mouth and can re-seal the bottle mouth. A protection mechanism 3 for improving the service life of the silicone plug body 1 is provided on the outer surface of the silicone plug body 1, and a taking-out mechanism 4 for facilitating the taking out of the silicone plug body 1 is provided on the upper surface of the plug cover 2.

[0021] Among them, the cross-sectional shape of the bottom of the silicone plug body 1 is an inverted isosceles trapezoid. Setting the cross-sectional shape of the bottom of the silicone plug body 1 as an inverted isosceles trapezoid can facilitate the entry of the silicone plug body 1 into the bottle mouth. The plug cover 2 is made of plastic material. A sealing rubber sleeve layer 5 is fixed on the top of the silicone plug body 1. By providing the sealing rubber sleeve layer 5 on the outer surface of the silicone plug body 1, the sealing performance at the bottle mouth is better.

[0022] Please refer to Figure 2, To facilitate the entry of the silicone plug body 1 into the bottle mouth, the protection mechanism 3 in this embodiment includes a sealing layer 301 provided on the outer surface of the silicone plug body 1. The provided sealing layer 301 is a polytetrafluoroethylene layer. Due to its excellent chemical corrosion resistance, high temperature resistance, low friction coefficient, good electrical insulation performance, and wear resistance, the polytetrafluoroethylene coating exhibits excellent sealing effects in multiple fields. An insulating layer 302 is provided outside the sealing layer 301. The provided insulating layer 302 is a graphite coating. The graphite coating has good high temperature resistance and is an environmentally friendly material. This characteristic enables the graphite coating to withstand extremely high temperatures and is widely used in environments that require high temperature resistance. An anti-aging layer 303 is provided outside the insulating layer 302, and a corrosion-resistant layer 304 is provided outside the anti-aging layer 303. The corrosion-resistant layer 304 is an epoxy resin layer. Epoxy resin has various excellent physical properties such as heat resistance, corrosion resistance, and wear resistance, and can maintain the integrity of the coating under complex working conditions. Epoxy resin anti-corrosion can be used for the internal and external wall coating of equipment such as pipelines, containers, and storage tanks to effectively prevent the corrosion of metal substrates by chemicals. A lubricating layer 305 is provided on the outer surface of the corrosion-resistant layer 304. A waterproof layer 306 is provided on the lower surface of the silicone plug body 1. The provided waterproof layer 306 is a polypropylene layer. Polypropylene has good chemical stability and waterproof performance and is suitable for the waterproof treatment of bottle plugs, thereby avoiding chemical reactions when the liquid in the bottle body touches the silicone plug body 1 and protecting the service life of the silicone plug body 1.

[0023] Among them, the sealing layer 301 is a polytetrafluoroethylene layer, the insulating layer 302 is a graphite coating, the anti-aging layer 303 is a polyurethane layer. Polyurethane has certain anti-aging performance. When polyurethane is applied to the metal surface as a coating, adhesive, or sealant, it can form a dense protective film to prevent corrosive substances from contacting the metal, thereby slowing down the corrosion process and achieving anti-aging. The corrosion-resistant layer 304 is an epoxy resin layer, and the lubricating layer 305 is silicone oil. When pushing in the silicone plug body 1, silicone oil can be coated on the outer surface of the silicone plug body 1 and below the sealing rubber sleeve layer 5 to facilitate improving the smoothness of pushing in the top of the silicone plug body 1. The waterproof layer 306 is a polypropylene layer.

[0024] Please refer to Figure 3 , To facilitate the removal of the silicone plug body 1 from the bottle mouth, the removal mechanism 4 in this embodiment includes a fixing block 401 fixed on the upper surface of the plug cover 2. A connecting ring 402 is fixed on the upper surface of the fixing block 401. The user can pass their finger through the connecting ring 402 and then pull upward, which can generate an upward pulling force on the fixing block 401 and the plug cover 2. An anti-slip sleeve 403 is fixed on the outer surface of the connecting ring 402. The anti-slip sleeve 403 is provided on the outer surface of the connecting ring 402 to increase the friction between the user's hand and the connecting ring 402, thereby facilitating the removal of the silicone plug body 1 from the bottle mouth.

[0025] Among them, the anti-slip sleeve 403 is a rubber sleeve.

[0026] The working principle of the above embodiment is as follows:

[0027] (1) By providing the plug cover 2 on the upper surface of the silicone plug body 1, the plug cover 2 can prevent the silicone plug body 1 from completely entering the bottle mouth and can re-seal the bottle mouth. A sealing rubber sleeve layer 5 is provided on the outer surface of the silicone plug body 1, so that the sealing performance at the bottle mouth is better. The bottom cross-sectional shape of the silicone plug body 1 is set as an inverted isosceles trapezoid, which is convenient for the silicone plug body 1 to enter the bottle mouth. The sealing layer 301 is a polytetrafluoroethylene layer. Due to its excellent chemical corrosion resistance, high temperature resistance, low friction coefficient, good electrical insulation performance and wear resistance, the polytetrafluoroethylene coating shows excellent sealing effects in many fields. The heat insulation layer 302 is a graphite coating. The graphite coating has good high temperature resistance and is an environmentally friendly material. This characteristic enables the graphite coating to withstand extremely high temperatures and is widely used in environments that require high temperature resistance. The anti-aging layer 303 is a polyurethane layer. Polyurethane has certain anti-aging properties. When polyurethane is applied to the metal surface as a coating, adhesive or sealant, it can form a dense protective film to prevent corrosive substances from contacting the metal, thereby slowing down the corrosion process and achieving anti-aging. The corrosion-resistant layer 304 is an epoxy resin layer. Epoxy resin has a variety of excellent physical properties such as heat resistance, corrosion resistance and wear resistance, and can maintain the integrity of the coating under complex working conditions. Epoxy resin anti-corrosion can be used for the inner and outer wall coating of equipment such as pipelines, containers and storage tanks to effectively prevent the corrosion of chemical substances to the metal matrix. The lubricating layer 305 is silicone oil. When pushing the silicone plug body 1, silicone oil can be coated on the outer surface of the silicone plug body 1 and below the sealing rubber sleeve layer 5 to facilitate the smooth pushing of the top of the silicone plug body 1. The waterproof layer 306 is a polypropylene layer. Polypropylene has good chemical stability and waterproof performance and is suitable for the waterproof treatment of the bottle plug. Thus, when the liquid in the bottle body touches the silicone plug body 1, chemical reactions can be avoided, and the service life of the silicone plug body 1 is protected.

[0028] (2) When pulling out the silicone plug body 1, the user can pass their fingers through the connecting ring 402 and then pull upward, which can generate an upward pulling force on the fixing block 401 and the plug cover 2. An anti-slip sleeve 403 is provided on the outer surface of the connecting ring 402, which can be used to increase the friction between the user's hand and the connecting ring 402, so as to facilitate pulling out the silicone plug body 1 from the bottle mouth.
