Wasserflasche vs. Trinkflasche vs. Feldflasche
While Wasserflasche, Trinkflasche, and Feldflasche all refer to containers for liquids, their usage depends heavily on the context, material, and intended purpose of the bottle.
Wasserflasche
A1This is the most general and literal term for a bottle specifically containing water. It often refers to the single-use plastic bottles bought at supermarkets, glass bottles served at a dinner table, or simply any bottle that currently holds water.

(Can you please bring me a water bottle from the supermarket?)

(We don't have a water bottle left in the fridge.)
Trinkflasche
A2This word implies a reusable bottle intended for personal hydration on the go. It is commonly used for sport bottles, squeeze bottles, or sturdy containers taken to school, the gym, or work.

(Do not forget to pack your drinking bottle for P.E. class.)

Feldflasche
B2This translates to canteen and refers to a rugged, often flat-sided bottle designed for military use, scouting, or extreme outdoor activities. It is usually meant to hang on a belt and often comes with a felt or fabric cover.

Summary
Use Wasserflasche for generic bottles (often disposable or table service) containing water. Use Trinkflasche for personal, reusable bottles taken to school, sports, or work. Use Feldflasche when referring to a military-style canteen or heavy-duty camping gear.
