'Kuaiguale' is a very vivid Chinese term that refers to the most common type of beverage bottle cap in our daily lives that needs to be forcefully unscrewed and makes a 'pop' sound. 

The "Break Break" bottle cap system is a complete bottle cap system, officially known as the "Twisted Anti theft Aluminum Plastic Composite Cap" or "Safe Cap". Its design core is "anti-theft" and "one-time verification". 

Literal interpretation: 

'Break': describes the action that requires force to open. 

'Le': describes the sense of satisfaction and confirmation that comes from the crisp broken vocal cords. 

From a functional perspective: 

It is a safety device that ensures that the product has not been turned on before reaching the consumer's hands. 

Working principle and structure 

The cleverness of this bottle cap lies in its structure, which usually consists of the following parts: 

Bottle cap body: The part used to unscrew and cap. 

Anti theft ring: a plastic ring at the bottom of the bottle cap. 

Connecting Bridge (or "Broken Bridge"): This is the most critical component! It is a very small plastic "bridge" that connects the bottle cap body and the anti-theft ring. When consumers first unscrew the bottle cap, these fragile "bridges" will be twisted apart, causing the anti-theft ring to separate from the bottle cap body and make a "pop" sound. 

Internal sealing gasket: There is usually a soft gasket inside the bottle cap, which is responsible for tightly contacting the bottle mouth to achieve sealing and prevent liquid leakage. 

Why is it important? 

Anti counterfeiting and anti-theft: This is its core mission. Once the 'connecting bridge' breaks, it cannot be restored. Consumers can easily determine whether this bottle of beverage is being opened for the first time, effectively preventing the product from being maliciously adulterated, contaminated, or swapped. 

Security guarantee: Provides consumers with intuitive security guarantees, especially when purchasing beverages in public places. 

Sealing and gas retention: For carbonated beverages, it can effectively seal and maintain the "sufficient gas" state of the beverage. 

Typical opening experience 

Pick up a new bottle of mineral water or cola. 

Rotate the bottle cap counterclockwise with force. 

At the same time as feeling resistance, hear a crisp "pop" sound. 

Seeing the circular structure at the bottom of the bottle cap separated from the main body (but usually still connected). 

This complete process is the reason why it is called "breaking music". 

Summary 

'Kuaiguale' is the commonly used but intricately designed anti-theft cap for beverage bottles. Although it is a small component, it is an important part of ensuring our food safety. The next time you unscrew the bottle cap, the loud "pop" sound is a conscientious message to consumers: "The product is safe, please feel free to drink it."
