Key Differences
While a canister is often cylindrical in shape, not all cylinders are canisters. The key distinction lies in the purpose and functionality: canisters are specifically designed for storage, with features like lids to secure their contents, whereas cylinders might not be designed to hold anything at all, serving instead as components in machinery or simply as objects studied in geometry.
The material composition of canisters can vary widely, from metal to plastic to glass, depending on their intended use. They are crafted to be durable and often decorative, especially those used in kitchens. Cylinders, when referring to objects rather than geometric figures, can be made from metal, plastic, or other materials suited to their specific applications, such as withstanding high pressures in the case of gas cylinders.
Understanding the difference between a canister and a cylinder is important for practical reasons, especially in contexts where the shape of an object might be described geometrically (cylinder) or by its intended use (canister). This distinction is particularly relevant in design, manufacturing, and everyday conversation when specificity is required to avoid confusion.

A solid geometrical figure with straight parallel sides and a circular or oval cross section.
Canister
A small plastic container used for storing a roll of film.
Cylinder
A piston chamber in a steam or internal combustion engine.
Canister
A metal container that holds pressurized gas, as one containing tear gas that explodes on impact or one containing oxygen as part of a breathing apparatus.
Cylinder
A cylinder-shaped container holding liquefied gas under pressure.
Canister
A metallic cylinder packed with shot that scatter upon discharge from a cannon, formerly used as an antipersonnel round.

Canister
The part of a gas mask that contains the filter for removing toxic agents from the air.
Cylinder
The surface generated by a straight line intersecting and moving along a closed plane curve, the directrix, while remaining parallel to a fixed straight line that is not on or parallel to the plane of the directrix.
Canister
A cylindrical or rectangular container usually of lightweight metal, plastic, or laminated pasteboard used for holding a dry product (as tea, crackers, flour, matches).
