All-Plastic and Recyclable: More and more products are adopting an all-plastic structure (such as U-shaped plastic springs replacing metal springs), allowing for direct disposal into recycling bins after use, making them more environmentally friendly.

Replaceable Core Components: Damaged straws, located deep at the bottom of the bottle, can be easily removed and replaced, eliminating the need to discard the entire nozzle.

High Corrosion Resistance: Key internal seals are often made of fluororubber (Viton), resistant to alcohol, cleaning agents, weak acids, and alkalis.

Minimum Number of Parts: The most sophisticated designs can reduce the number of parts to just six (including the straw and ball valve), resulting in a very low failure rate.

Stable Connection: Securely fastened to the bottle body via threads, it won't loosen even when shaken while full of liquid, ensuring excellent sealing.

Mature Standard Mold: The widely adopted standardized 28/400 and 28/410 threaded interfaces have become industry-standard, making parts readily available and assembly convenient.
