In other words, in the conventional toy fireworks, two flames are present at the same time. Thus, the present invention, only the outer explosive layer is ignited during ignition, first only the outer explosive layer burns from one end to the other end, when the outer explosive layer burns out at the other end, the outer explosive layer Of the new toy fireworks (in other words, one flame from one end of the explosive part to the other) It moves to one end and the other end is so-called U
Toy fireworks that turned to return to the end), and
When ignited, only the outer explosive layer ignites, first only the outer explosive layer burns independently from one end to a desired midpoint, and then at the midpoint, the outer explosive layer fires to the inner explosive layer as well. After that, a new toy firework in which the outer explosive layer burns at a high burning rate to the other end of the explosive part, while the inner explosive layer burns in both directions from the midpoint at a low burning rate It was made in an attempt to provide.

着火温度ではなく、外側の火薬層の燃焼速度である。Means for Solving the Problems As a result of intensive research to develop such a novel toy fireworks, the present inventor has found the following facts. That is, when the burning rate of the outer explosive layer is high, even if the outer explosive layer burns, the heat accumulation effect sufficient to ignite the inner explosive layer is not performed, so the inner explosive layer does not ignite. However, at the ignition end of the explosive portion, the ignition powder that gives a large amount of heat enough to ignite the inner explosive layer must not adhere to the outer explosive layer. On the other hand, in order to ignite the inner explosive layer by the heat of combustion of the outer explosive layer, it is necessary to perform a heat storage action sufficient to ignite the inner explosive layer by lowering the burning speed of the outer explosive layer. Is. The above also applies when the ignition temperature of the inner explosive layer is lower than the ignition temperature of the outer explosive layer. What is important in the present invention is not the ignition temperature of the inner and outer explosive layers, but the burning velocity of the outer explosive layers.

に1個のみである。[Toy fireworks according to claim 1] In the toy fireworks according to claim 1, one end of the explosive portion having no ignition charge is ignited.
When this happens, the toy fireworks burn as follows (see Figure 2). (1) Only the outer explosive layer starts burning, and the inner explosive layer does not start burning. When one end of the explosive part that does not have an igniting charge is ignited, the outer explosive layer ignites and starts burning, but since the outer explosive layer has a high burning speed, even if the outer explosive layer burns, There is not enough heat storage to ignite the explosive layer. In other words, since the propagation speed of the combustion reaction is high in the outer explosive layer, the temperature of each part in the inner explosive layer cannot be raised to the ignition point even if the outer explosive layer burns. (2) Thus, only the outer explosive layer continues to burn, and the fire approaches the other end of the explosive portion. (3) When the fire of the outer explosive layer reaches the burning velocity lowering means provided at the other end of the explosive portion, the burning velocity of the outer explosive layer is significantly reduced. Therefore, by burning the outer explosive layer,
The heat storage effect is sufficient to ignite the inner explosive layer. In other words, the outer explosive layer, at the other end of the explosive part, has a lower propagation velocity of the combustion reaction due to the combustion velocity lowering means, so that the other end of the inner explosive layer due to the combustion of the outer explosive layer The temperature can be raised to the ignition point. Therefore, the fire of the outer explosive layer moves to the inner explosive layer at the other end of the explosive portion, and the inner explosive layer starts to burn, but the outer explosive layer burns out at the other end of the explosive portion. (4) In this way, only the inner explosive layer burns from the other end of the explosive portion toward the one end. In summary, in the toy fireworks according to claim 1, when one end of the explosive part is ignited, first, only the outer explosive layer burns to the other end of the explosive part, and subsequently the fire moves to the inner explosive layer and "U". "Turn" and return to the one end of the explosive section.
In other words, in the toy fireworks of claim 1, the number of flames is always only one.

(2) When the fire of the outer explosive layer reaches the burning speed reducing means provided on the surface of the outer explosive layer at a desired position between the one end and the other end of the explosive portion, the outer explosive layer is burnt for The fire of the explosive layer also transfers to the inner explosive layer at the midpoint, and thereafter the inner explosive layer and the outer explosive layer also burn. The inner explosive layer burns in both directions. At this point, the number of flames is three. (3) The outer explosive layer still burns toward the other end of the explosive portion, but since the outer explosive layer has a high burning speed, the outer explosive layer advances ahead of the inward explosive layer in the same direction. in the meantime,
