The story

A false friend can be found in North Germanic: dunk (‘canister, keg’), 17th c. tönk, which appears derived from both Low German tunneke, Dutch tonneke (diminutive of "barrel"), and dunka (‘to dunk, to dip under water, to moisten’).

Today it means

noun A closed container for liquids or gases.
