Capacity: 350ML ? ??Location: United States
Absolute leak of secret Nalgene
Cap: All caps are based on high-quality plastic， and then casting made according to precise size， and bottle Devoted bite without clearance.
Square and triangular spiral teeth: Usually the cheap bottles for cost savings is the use of screw caps teeth tooth round face， but Nalgene leakproof effect in order to pursue the best use of the square and triangle spiral teeth， the inner and outer tooth Devoted bite， no gap， thus greatly reducing the chance of leaks， although the square tooth mold accuracy requirements are very high， and the production process 亦较 complexity to the cost increase， but still worth a Nalgene think.

Cap-tight ring: old bottle generally will add a cushion in the bottle， the bottle is used for preventing leakage withstand use， but after a long time with this rocky cushions will lose due to prolonged pressure elastic and leaks， Nalgene abandoned this old method， but in the ring cap cast a slope， the slope and the finish of its slope exact match， both when the cap is automatically joined to the rotation， up to to the effect is ly leak-proof， the high and the leak-proof and long-lasting effect than.
