Description

[Detailed Description of the Invention] The present invention relates to a toy firework that flies through the air using the thrust produced by the gunpowder contained within it.

Conventional toy flying fireworks use a paper pipe loaded with gunpowder and a fuse, and the firework itself is attached to the tip of a bamboo or wooden mounting rod.
In other words, the firework body and the mounting rod are integrally formed by pasting thin paper around them.

For this reason, when the cinders fell to the ground, there was a risk that they would come into contact with combustible materials such as dry grass and cause a fire.

The purpose of the present invention is to eliminate the risk of fire outbreaks and to improve the efficiency of the fireworks manufacturing process. The gist is that the firework body and the mounting rod are fixed together by circumferentially pasting metal foil on the firework body and the mounting rod.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a firework body made of a cylinder with a bottom made of plastic, and a small amount of gunpowder 2 is filled in the inner part of the firework body 1 to cause the firework to fly through the air while emitting a flying sound.

The gunpowder 2 may be, for example, a mixture of potassium perchlorate, sodium salicylate, and saltpeter, or a mixture of potassium picrate, potassium perchlorate, and saltpeter.

A thread-wound fuse 3 is attached in contact with the gunpowder 2, and the other end of the fuse is extended to the outside of the firework body 1.

A plastic cap 4 made of soft vinyl resin or the like is attached to the front part 1a of the firework body 1 constructed in this manner so as to have a gap 8 therein.

The fireworks body 1 constructed as described above is arranged in parallel with the tip of a bamboo or wooden mounting rod 5 formed to an appropriate length, and the surfaces of the fireworks body 1 and the mounting rod 5 are pasted around the surface with a metal foil 6 to be integrated. Fixed to.

The metal foil 6 is preferably an aliminium foil from the viewpoint of handling and cost, and is coated with adhesive on the entire back surface, but product information or handling precautions can be displayed on the front surface.

Further, the end of the fuse 3 extended to the outside of the pre-firework main body 1 is fixed to the mounting rod 5 with cellophane tape 7 or the like.

In the present invention constructed in this manner, the firework body 1 made of a plastic cylinder formed by integral molding has good shape stability, making it easy to fill the gunpowder, etc.
The mounting rod 5 can be fixed to the mounting rod 5 simply by circumferentially pasting the metal foil 6 coated with an adhesive, so it can be manufactured extremely efficiently.

In addition, when used by players, the tri fireworks body is constructed to be sturdy, so it will not be damaged during transportation, so there will be no problems such as explosions. If the cylindrical body melts or breaks, it is protected by the metal foil 6 surrounding the surface and will not explode.

Furthermore, even if the soft plastic cap 4 attached to the forehead 1a of the firework body 1 flies in an unexpected direction and hits a human body or glass, the soft plastic cap 4, together with the air gap 8, will prevent an impact. This can be an effective safety measure in the event that the forehead 1a melts due to heat, or in the unlikely event that an explosion occurs.

Incidentally, it is possible to store a sonorous gunpowder in the cap 4 as required.

As mentioned above, the flying fireworks of this invention greatly streamlines the manufacturing process and provides high-quality fireworks, and also takes into account safety during play, with no risk of accidental explosions. Safety measures have been taken in the event of an unexpected accident, and since it does not use self-combustible paper like conventional products, it has many advantages such as eliminating the possibility of fires caused by cinders.
