FORMING METHOD OF DETONATOR OF SIGNAL CYLINDER, AND SIGNAL CYLINDER BY SAME METHOD

摘要

PROBLEM TO BE SOLVED: To provide a signal cylinder which ignites and burn safely and securely by automatically forming a detonator of an even thickness without relying on monitoring and adjustment by a visual observation by an operator as long as under a certain operation condition. SOLUTION: The detonator 1 is fixed by projecting a little from an outer side surface of a signal cylinder main body 9 on a peripheral edge part around an opening part of a top part of the signal cylinder main body 9 with a flaming agent or a fuming agent filled inside. A rubbing powder sheet with rubbing powder applied annularly on an inner surface lower end is bonded on an inner surface of a cylindrical lid 11. A soft resin sheet cushion material 5 for contact prevention is arranged annularly on the signal cylinder main body 9 between the detonator and rubbing powder. The signal cylinder ignites by pulling the cylindrical lid 9 upward while slightly rotating. Three to five pieces of space interval adjusting parts 14 spaced apart in a horizontal direction between the detonator 1 and the soft resin cushion material 5 form the detonator 1 in the peripheral edge part around the opening part of the top part of the signal cylinder main body 9 in the even thickness.
