Therefore, the inner cylinder emits smoke when it is launched, in addition to the emission of flying objects.

A fourth aspect of the present invention is the invention of the second aspect, wherein the main body and the cap of the inner cylinder are formed of biodegradable plastic.

[0013] Biodegradable plastics degrade naturally in soil. Therefore, after the launch, it is not necessary to collect.

[0014]

FIG. 1 shows an embodiment of the present invention. A toy launch fireworks 1 of this embodiment has an outer cylinder 2 having an opening 2 formed at one end and inserted into the outer cylinder 2. And an inner cylinder 4 provided. An eave 5 made of cement, gypsum or the like is provided inside the outer cylinder 2 on the opposite side of the opening 2, and a propellant 6 for launching the inner cylinder 4 is arranged on the eave 5. A squib 7 is connected to the propellant 6, and one end of the squib 7 is drawn out of the outer cylinder 3.

On the other hand, the inner cylinder 4 includes a main body 11 and a main body 11.
And a cap part 12 attached to the head.

FIG. 2 shows the inner cylinder 4, and the main body 11 is composed of divided bodies 11a and 11b divided into two by a dividing line 13, and assembled by abutting the divided bodies 11a and 11b. A large number of flying objects 14 are stored inside the main body 11 in this assembled state.

The flying object 14 is made of a piece of paper or the like cut into strips or small pieces, and includes gold, silver, red, blue, yellow, green, white,
Those printed in purple and other colors are combined in a plurality of colors and stored in the main body 11. The scattered matter 14 is released into the air by the rupture of the inner cylinder 4, thereby flying as confetti and flying in the air, and by enjoying the confetti, the interest is increased. The flying object 14 is not limited to a paper piece, but may be a plastic piece or a metal piece.

The cap 12 of the inner cylinder 4 is attached to one end of the main body 11 as described above. The cap portion 12 is fitted to the main body portion 11 from the outside, thereby preventing the main body portion 11 from being separated into the divided bodies 11a and 11b. By attaching the cap portion 12 of the main body 11 in this manner, the scattered matter 14 in the main body 11 is isolated from the explosive 6 in the outer cylinder 3. Therefore, even if the explosive 6 explodes, the scattered matter 14 in the main body 11 can be prevented from burning.

The cap portion 12 has an outer wall 15 and an inner wall 16, and a space defined by these walls 15, 16 has a mixed explosive 17 of a splitting agent and a smoked agent.

As a result of this ignition, the splitting agent of the mixed explosive 17 explodes and ruptures the inner cylinder 4, and the smoked agent burns to generate smoke. Reference numeral 19 denotes a discharge hole formed at an appropriate portion of the cap portion 12 for discharging the generated smoke to the outside. In addition, as the smoke medicine, it is preferable to use a plurality of smoke medicines of different colors in combination, whereby smoke of a plurality of colors can be generated at the same time, which further enhances interest.

In the inner cylinder 4 having the above structure, the entire body 11 and cap 12 are formed of biodegradable plastic. The biodegradable plastic is a plastic that degrades naturally in the soil. By using this plastic, there is no need to collect it after launch, and it is safe for the environment. As such a biodegradable plastic, a biodegradable aliphatic polyester having a trade name of "Bionole" (manufactured by Showa Polymer Co., Ltd.) can be selected.

The fireworks of this embodiment are used in a state where the lower part of the outer cylinder 3 is embedded in the ground and the surroundings are hardened with pebbles or the like so as not to fall down. In this state, the squib 7 is ignited. Due to this ignition, the explosive 6 ignites and explodes,
Due to this explosion, the inner cylinder 4 is launched upward from the opening 2 of the outer cylinder 3.

The fired inner cylinder 4 ignites the squib 18 and ignites the mixed explosive 17 in the cap portion 12.
The explosive explosion explodes and the inner cylinder 4 explodes, and the smoked medicine burns, and the smoke of a plurality of colors leaves a tail. Also, due to the rupture of the inner cylinder 4, the scattered matter 14 is released into the air and becomes confetti and dances in the air. Therefore, the viewer can appreciate the confetti, increase interest, and excite the event.
