Torch or other gas fueled appliance and more particularly a coupling for connecting a fuel canister to a torch head or other appliance

摘要

A coupling for attaching a fuel canister (1) to an appliance such as a torch (2) is provided that comprises a first connector (6) on the canister (1). The first connector (6) comprises a first set of screw threads (20) where the first set of screw threads (20) are interrupted to define a shape. A second connector (12) is provided on the appliance or torch (2) where the second (12) connector comprises a locking element (40). The locking element (40) has a matching shape that matches the shape such that the locking element (40) closely receives the first connector (6) when the first connector (6) is in a first orientation relative to the second connector (12). A method of using the coupling is also provided where the appliance (2) is rotated relative to the canister (1) less than 360 degrees.
