[3] Introducing a small, blue, refillable gas cylinder, directly fitted with special stoves and Welsbach mantle lanterns, the company rapidly expanded to foreign markets.

Inserting an original Campingaz canister into the device pierces it and, once the appliance's valve is opened, allows the fuel gas to flow.

Pierceable canisters must be completely empty before they are removed from the appliance, otherwise the remaining gas will escape and become a fire hazard.

There is also a range of "Plus" self-sealing valve-type canisters, such as the CV 300 Plus, which can be disconnected and reconnected when not empty when they are fitted to compatible devices with the Easy Clic plus connection.

These are typically used for appliances like multi-ring cookers, gas refrigerators, grills or heaters and are frequently used in boats, caravans and motorhomes in Europe.
