Abstract

(57) [Summary] [Purpose] Utilizing the fact that metal powders are flame retardant compared to explosives and are less likely to ignite, and weaken the ignition power from external fires such as jumps to improve safety. [Structure] A metal powder coating layer 4 is coated on the outer surface of a coating material portion 2 coated on the small shaft 1. [Effect] The metal powder coating layer weakens the ignition power from an external fire such as a flying flame, and can significantly improve safety. Further, the paint powder portion in the inside plays a role of a squib and can burn the metal powder on the outside.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a toy fireworks with high safety that does not cause fire burning or spontaneous ignition.

[0002]

[Prior art]

 Conventionally, for example, a so-called sparkler firework in which a paint powder portion 2 is formed by coating on one end portion of a small shaft 1 as shown in FIG. 1, or a paint applied on one end portion of the small shaft 1 as shown in FIG. There are known toy fireworks such as inner and outer two-layer paint-based fireworks, in which the paint portion 3 is coated on the outer surface of the portion 2 by coating.

[0003]

[Problems to be solved by the device]

 However, in these conventional toy fireworks, the paint powder part is exposed and exposed on the outer surface, so that the fireworks of another person's fireworks fly to the paint part of the external surface of their fireworks and catch fire. However, there was a possibility of so-called fire burning, which was a safety issue.

The present invention has been made to solve the above-mentioned problems of the prior art, and takes advantage of the fact that metal powders are flame-retardant and harder to ignite than explosives, and can be used to protect against external fires such as jumps. The purpose is to further weaken the ignition power and improve safety.

[0005]

[Means for Solving the Problems]

 The gist of the present invention resides in a toy firework in which a metal powder coating layer is coated on the outer surface of the powder coating portion coated on the small shaft. Next, the present invention will be described with reference to FIG.

First, reference numeral 2 is an explosive charge portion applied to the tip of the small shaft 1. Therefore, in the present invention, the coating layer 4 of the metal powder, which is harder to ignite than the explosive, is coated on the outer surface of the coating powder portion 2.

[0007]

[Effect of device]

 As described above, the toy fireworks of the present invention has the flame-retardant metal powder coating layer coated on the outer surface of the powder coating portion coated on the small shaft, which is harder to ignite than the powder. As a result, the metal powder coating layer weakens the ignition power from external fire such as a jump and can significantly improve safety. In addition, the paint powder part in the inside plays a role of a fuse and can burn the metal powder outside.
