Nalgene bottles have many features which set them apart from the rest. Here are a few highlights of each bottle:
- The closure walls are heavy duty, uniform, and generally thicker than the competition, making them very resistant to splitting or puncturing.
- The closure is one-piece and linerless, setting the foundation for a leakproof system.
- An inner ring seal is molded-in and fits tightly against the beveled inner edge (chamfer) of the bottle neck, guarenteeing a leakproof system.
- The cap threads are continuous, straight-shouldered semi-buttress threads, not low-quality round threads.
- Most Nalgene bottles feature a shrink ring at the neck that is molded so that the inside surface is smooth, minimizing content entrapment.
- The bottom has curved inner corners for easy cleaning and a stable base with permanent molded-in resin code and volume.
- Nalgene bottles and carboys do not contain extenders or plasticizers such as phthalates (except for the PVC), which eliminates a source of sampling contamination.
- Unlike a lot of plastic bottles, most Nalgene bottles up to 4 liters are injection blow-molded, which allows for more precise molding of the neck area and chamfer and more uniform wall thickness. Injection blow-molded bottles feature a smoother, more stable bottom with less molded-in stress for greater product reliability. Furthermore, there are no pinch-offs to cause creases or splits which could harbor contaminants.
