spillproof
Designed against spills
Spillproof describes containers, lids, or surfaces designed to prevent liquids from escaping or causing a mess.
A spillproof cup for toddlers has a valve that stops drinks from pouring out when tipped.
The term applies broadly to anything engineered to contain liquids even when jostled, inverted, or knocked over: spillproof travel mugs, spillproof keyboards.
Like similar compound adjectives, it promises a degree of protection rather than absolute immunity to spills.
