PROBLEM TO BE SOLVED: To provide a cracker producing low emission sound, generating longer flying distance than that of the conventional one, operable in one hand and capable of being repeatedly used.SOLUTION: This invention relates to a cracker using a mechanism for injecting band-like tapes or paper pieces through repelling force of a coil spring and wound tapes or paper pieces are arranged inside the shrunk coil spring. Since a spring type tape injection cracker does not use any explosive, but utilizes a spring, its injection sound is lower than that of the usual cracker and no smoke is produced. Further, since its one-hand operation can be performed and the tapes are already stored in the spring, a size of the cracker can be reduced to a shape similar to that of a cylinder having a diameter of 2.5 cm and a height of 5 cm and the cracker can be handled easily by adult man's one hand. Further, since the spring is shrunk by a screw-type lid, it is possible to shrink the spring in a relatively easy manner. Since repelling force of the spring is utilized, it can be repeatedly utilized.SELECTED DRAWING: None |
