Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a tubular toy fireworks such as a fireworks display and a fireworks display. 2. Description of the Related Art Generally, fireworks for fireworks (fireworks) are used for toys.
As shown in FIG. 7, a propellant 3, a shooting ball (referred to as a “star”) 4, and the like are placed on a sealed bottom 2 in a paper tube 1 sealed by filling with an incombustible material 2 such as soil. An explosive portion 5 filled with an explosive is provided, a lateral hole 6 is opened in a side wall of the paper tube 1 corresponding to the explosive 3, and the explosive 3 is ignited by inserting a squib 7. Is done. [0003] In addition, as shown in FIG.
An explosive portion 5 formed by filling an explosive such as a propellant 3, a launch ball 4, and a delaying agent 8 is provided on a closed bottom portion 2 in a paper tube 1, and a squib 7 is inserted into the paper tube from an upper end opening of the paper tube 1. It is inserted. Reference numeral 9 denotes a combustible sealing material provided in the paper tube 1 to prevent the explosive from flowing out, 10 denotes a hollow portion in the paper tube 1 above the explosive portion 5, and 11 denotes an upper end opening of the paper tube 1. It is a thin paper that seals. [0004] By the way, the launch fireworks (fireworks) having the above structure cannot be lit by holding the lower portion of the squib 7 by hand because of the danger. It is necessary to ignite standing on the ground with a tool. This can lead to inappropriate support and an accident. Although it is possible to lengthen the lower portion of the squib in the structure shown in FIG. 7 as well, the cavity 10 above the explosive portion 5 becomes relatively short, so that the direction toward the launched sphere 4 is reduced. There is a danger that it may fly in an unexpected direction without imparting properties. Further, in the launch fireworks (fireworks), all the shooting balls are suddenly fired at the same time as the propellant 3 is ignited, so that there is a drawback that an interest like blowing fireworks cannot be obtained. On the other hand, the blowing fireworks shown in FIG.
Can be fired in order from the top one,
It is necessary to pass a long squib 7 through the cavity 10,
Depending on how it is fixed, the squib 7 may fall off during the transfer, and since the squib 7 is long, it may take a long time to ignite from the sparks and blow out the sparks. Because of the large number, there is a danger that fire powder will blow out as soon as you look into the upper end opening, leading to an accident. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a tubular toy fireworks which is highly safe and can be varied in various interesting phenomena. For this purpose, the tubular toy fireworks of the present invention form an explosive portion by filling an explosive, such as a propellant, a launch ball, or a delaying powder, on the closed bottom of the paper tube, and the inside of the paper tube above the explosive portion is hollow. A horizontal hole is formed in a side wall of the paper tube corresponding to a substantially boundary between the explosive portion and the hollow portion, and a fuse is inserted through the horizontal hole. Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a tubular toy fireworks according to the present invention, wherein 1 is a paper tube, 2 is a closed bottom portion of the paper tube 1 which is closed by filling with an incombustible material such as soil, and 5 is a paper tube inside. An explosive portion 9 composed of a propellant 3, a firing ball 4, a delaying agent 8, and the like filled on the incombustible material, 9 is a flammable sealing material provided in the paper tube 1 to prevent the explosive from flowing out, A hollow portion 11 in the paper tube 1 above the explosive portion 5 is thin paper sealing the upper end opening of the paper tube 1. In the present invention, a horizontal hole 6 is formed in a side wall of the paper tube 1 corresponding to a substantially boundary between the explosive portion 3 and the hollow portion 10, and a squib 7 is inserted through the horizontal hole. In the tubular toy fireworks thus constructed, the squib 7 may be short enough to penetrate the side wall of the paper tube 1, and the squib 7 ignites the upper portion of the explosive portion 5 in a short time. First, a spark is blown out from the upper end opening by burning the delaying medicine 8, and then the propellant 3, the firing sphere 4
And the firing sphere 4 can be fired, which has the same effect as the fireworks. In addition, since the hollow portion 10 can be sufficiently long, the firing direction of the shooting ball 4 can be adjusted, so that the possibility that the fireball will fly in an unexpected direction and cause a burn or a fire is reduced, and the lower side of the squib 7 Since a sufficient length can be obtained, it is also possible to ignite the squib 7 by hand and play safely without considering means for standing on the ground. Further, the embodiment shown in FIGS.
A plurality of the tubular toy fireworks according to the present invention are housed in a cardboard case 17 and fire balls are fired one after another by one ignition by connecting them with a squib. It is. That is, the tubular toy fireworks are wound in thin paper 16 and arranged four by four in a straight line.
Are arranged in three rows, the upper portions of the respective tubular toy fireworks are projected from the upper surface of the case 17, and the squib wires 12, 13, 14 are serially wired to the respective tubular toy fireworks in the case 17. Then, the tips of the squibs 12 and 13 are adhered to an adhesive tape 15.
By winding them together and projecting them out of the side surface of the case 17, each of the tubular toy fireworks is configured to be ignited in turn if the tip is ignited. The toy fireworks can also be commercialized in such an embodiment, whereby each squib is hidden in the case 17 and thus has a neat appearance, and the possibility that the squib is detached can be reduced. As described above, in the tubular toy fireworks of the present invention, a horizontal hole is formed in a side wall of the paper tube corresponding to a substantially boundary between the explosive portion and the hollow portion in the paper tube. Since the squib is inserted through the hole, the following effects are obtained. Since the length of the squib can be shortened like a conventional toy fireworks after securing a sufficient length in the cavity, the squib can be attached stably and the time until ignition of the gunpowder can be shortened It does not seem to disappear, and since the direction of the launching ball is stabilized, safety is ensured. Since the ignition is carried out from the upper portion of the explosive portion, variations of interesting phenomena such as conventional blowing fireworks are possible, such as firing a firing ball without blowing a firing ball and then firing a firing ball. Since the lower part of the fuse can be lengthened and the paper tube can be ignited directly by hand, there is a danger that accidents may occur due to improper support on the ground as in the past. And increase safety.
