<p>The purpose of the present invention is to provide a case for firecrackers which allows improvement of productivity of products and reduction of manufacturing unit costs by reducing and simplifying manufacturing processes through accommodation of ignition strings drawn from the lower end in a stable manner without using an adhesive tape. To achieve the purpose, the present invention provides a case for firecrackers which erupts various built-in color papers or paper tapes by explosion of explosives at the tip of a built-in ignition string by pulling of the ignition string and comprises a main body having a drawing-out hole having a cone shape with a wide upper end and a narrow lower end with the ignition string being drawn out from inside at the lower end and a insertion hole with the ignition string drawn out from the drawing-out hole being inserted inside formed to be separated; and a protruding tip integrally formed in protrusion from the lower end of the main body and communicated with the drawing-out hole. According to the present invention, the ignition string is processed simply and quickly by drawing out the ignition string under stable guidance and accommodating the drawn-out ignition string through re-insertion inside to allow drawing out at the same time, so that productivity and production efficiency of firecrackers are improved, cost competitiveness of products are enhanced by reducing expenditure of labor costs and material costs, and a beautiful appearance is obtained as well as risks for explosion accidents by firecrackers is prevented beforehand.</p> |
