PURPOSE:To apply shear force on soup or the like adhered to surfaces between engaging part and facilitate the separation of both surfaces by a method wherein a relative positioning device for an auxiliary flame port and an ignition burner is provided with an arced relief on either a burner main body or a burner cap while the engaging part is provided on the other part and the length of the arc of the relief is made longer than the length of the engaging part. CONSTITUTION:An auxiliary flame port 5 is positioned so as not to be positioned on the extending line of the ignition flame of an ignition burner 7 in order to effect ignition for a main flame port 4 nicely. A positioning device 8 is constituted of an arced relief 9 or an arced notch 91 formed on the main body 1a of a burner and an engaging part 10 or a projected part 101 formed on one the teeth 3 of a burner cap 1b. When the burner cp is put on the main body of the burner so that the projected part 101 is placed in the arced notch 91 and the burner cp is pivoted, the projecting part 10 is retained by one of the ends of the notch 91 whereby the ignition flame of the ignition burner 7 may pass through an intermediate space between the auxiliary flame ports located at two places.
