The lighter has a reservoir (1000) containing a pressurised mixture (L) of an inflammable volatile liquid and a colouring agent, and a porous filter (1020) which is able to decompress the mixture as it is fed, at least partially in liquid form, to the exterior of the reservoir, where it is burned. It also has a device for supplying the liquid mixture to the filter. A capillary tube (1015) delivers the mixture to the exterior of the lighter after it has passed through the filter, and its internal diameter after the filter is between 0.25 and 0.4 mm. The capillary tube is linked to a vaporisation tube (1055) on the outside of the reservoir which is curved in shape, curling round the axis (U) of the flame and ending in line with the axis. The lighter burns a mixture of butane gas and methanol or ethanol with the colouring agent, which is either a metal salt or alkaline metal, depending on the colour to be produced. |
