leakproof
Sealed against spills
Leakproof describes containers, seals, or materials designed to prevent liquids or gases from escaping.
A leakproof water bottle won't spill in your bag; leakproof diapers contain what they're meant to contain.
The term applies broadly to anything engineered to maintain a barrier: leakproof containers, leakproof roofing.
Like similar compounds (waterproof, foolproof), it promises reliability but doesn't always deliver.
