Abstract

(57)【要約】 【課題】 爆発音を発して聴覚に訴えることに加え視覚 的要素を拡充して花火遊戯の興趣を増大させると共に、 爆発による危険性を著しく軽減させた玩具用音物煙火を 提供する。 【解決手段】 本発明の玩具用音物煙火1は、密閉体2 と、密閉体2内に充填された爆薬3と、一端4aが密閉 体2内に挿入され他端4bが外方に導出された導火線4 と、密閉体2を被包する外装部5とを有しており、外装 部5の少なくとも一部は爆薬3の爆圧により破壊される 脆弱部6となっている。
PROBLEM TO BE SOLVED: To improve the visual factor in addition to the auditory appeal through generation of an explosion noise, and to increase the elaboration of the fireworks play by forming a brittle part to be destroyed by the explosive pressure of the explosive. SOLUTION: A sealed body 2 is provided with an explosive storage space to be filled with the explosive 3 inside, and the explosive storage space is formed between one end of a fuse 4 and a bottom stop 2b. The fuse 4 is fitted in a condition where the sealability of the explosive storage space is kept, and the whole sealed body 2 is packed by an external part 5. The external part 5 is formed spherical by joining two semi-spherical bodies 5a, 5b with each other, and the semi-spherical bodies 5a, 5b are formed of a foamed material with a brittle part 6 thereto. The visual factor is improved in addition to the auditory appeal by the generation of the explosive noise, and the elaboration of the fireworks play can be increased, and the danger by the explosion can be reduced.
