canister

A canister is a small container with a lid, often made of metal. You might keep a canister of sugar in your kitchen next to a canister of tea.

Typically, a canister is round and has a fitted lid — while kitchen canisters are usually metal, the canisters that hold a roll of camera film are made of plastic. In the 15th century, the word meant "basket," from the Latin canistrum, "wicker basket," with its Greek root kanystron, "basket made of reeds." The meaning of canister probably changed to "metal container" because of the word can.
