Designed or constructed so as to prevent dripping; resistant to or protected from drips and spills.
From English 'drip' (imitative origin) + 'proof' (from Old French 'prove' meaning 'to test'), meaning 'resistant to dripping.'
Like 'drinkproof' and 'waterproof,' this compound uses '-proof' to market products as preventing a specific problem—though technically 'dripproof' is rarer than its cousin 'dripless' in actual usage.
