Key Selling Points at a Glance

Advantages of Snap Neck + Support Ring Design

• 卡扣颈（压口）vs 螺纹口：压口无需旋转，直接下压即密封，灌装速度更快，瓶盖成本更低，是桶装水行业的首选。

• 支撑环作用：在灌装线上被夹爪固定，防止桶倾斜或掉落；在清洗线上支撑翻转；运输过程中保护颈口不变形。

• 超宽克重范围：165g–800g 覆盖从一次性轻量桶（165g–300g）到 300+ 次循环超重型桶（730g–800g），一应俱全。

• 工厂直销价格：自有模具车间和注塑车间，成本可控，价格透明，量大更优。

• Snap Neck vs Screw Neck: Snap neck requires no rotation – direct downward pressure seals instantly – faster filling speed, lower cap cost – the preferred choice for bottled water industry.

• Support Ring Function: Fixed by grippers on filling lines – prevents tilting or falling; supports inversion on washing lines; protects neck from deformation during transport.

• Ultra-Wide Weight Range: 165g–800g covers lightweight disposable barrels (165g–300g) to 300+ cycle ultra-heavy barrels (730g–800g) – one product line for all needs.

• Factory Direct Price: In-house mold shop and injection workshop – cost controllable, price transparent – better value for volume orders.

FAQ

Q1: What is the difference between snap neck and screw neck? Which is better?
