What is special about the spiral bottle mouth design of the eyebrow pencil tube compared to other types of bottle mouths?

The spiral bottle mouth of the eyebrow pencil tube has good sealing and leakage prevention. The spiral bottle mouth is tightened in combination with the sealing ring of the bottle mouth to provide double sealing protection. This design can effectively prevent eyeliner or other liquid products from leaking during transportation, carrying or use, ensuring the safety and use effect of the product. The design of the spiral bottle mouth makes the connection between the bottle mouth and the bottle body tighter, and can maintain a stable sealing state even in bumpy or unexpected situations, reducing the problem of liquid leakage caused by poor sealing.
The user only needs to gently rotate to open or close the bottle mouth, which is easy and quick to operate. This design is particularly suitable for eyebrow pencil tube products that need to be used or carried frequently, which improves the user experience. The design of the spiral bottle mouth is usually closely matched with the internal refill or liquid container, allowing users to control the amount more accurately when using it to avoid waste.
The spiral bottle mouth is usually made of durable materials, such as ABS, aluminum, etc. These materials not only have excellent mechanical properties, but also have good corrosion resistance and wear resistance, which can ensure that the bottle mouth remains stable and durable during long-term use. The design of the spiral bottle mouth has been carefully calculated and optimized to ensure uniform force, smooth and non-stuck during rotation. At the same time, its structural design also takes into account the needs of anti-loosening and anti-leakage, improving the overall stability and reliability of the product.
The appearance design of the spiral bottle mouth can be customized and beautified according to product characteristics and market demand. For example, screw caps of different shapes, colors or patterns can be designed to increase the beauty and attractiveness of the product. Users can choose different spiral bottle mouth designs according to their preferences and needs, such as different rotation directions, rotation strengths or rotation feel, etc., to meet personalized use needs.
