Abstract: PROBLEM TO BE SOLVED: To provide a used paper mold spheric crust for skyrocket which has an adequate strength the does not damage an assembling property and crushability at the time of explosion, which is inexpensive and has a good mass-productivity and excellent in flame resistance and moisture resistance, and a method for manufacturing the same. SOLUTION: Used paper such as old newspaper or the like is processed into a pulp, followed by sheet forming and drying so as to obtain a used paper mold of recycling cardboard 16 having a semi-spherical shape. After being dipped in a solution of a water-soluble flame retardant and a waterproofing agent, the cardboard is dried, followed by thermal press working to obtain a smooth inner crust 1 having the inner and outer peripheral surfaces in pregnated with the flame retardant and the waterproofing agent and compressed. Due to the improvement in the strength of the inner crust 1 by the compression at the time of mounting a star 3 or a bursting charge 5, no recess is formed. Further, because of the smoothness, the star 3 does not suffer from friction or fall off of an explosive. Furthermore, sticking of brown paper to an outer peripheral surface can be conducted with ease.  Still further, as the inner crust is a used paper mold product, it is easily crushed into pieces at the time of star bursting charge explosion, thus preventing danger at the time of falling and preventing a design effect from being lost. In addition, a flame resistance performance and a moisture resistant performance are improved as much as possible due to the flame retardant and waterproofing agent impregnated and compressed in the inner and outer surfaces of the crust. Also, mass production is achieved and thus the crust can be manufactured at a low cost.
