  Below, the explosives fired explosive accommodating member 1 which is one suitable embodiment of this invention is demonstrated with reference to FIGS.

  The explosive fireworks launching explosive accommodating member 1 is a cardboard container tapered toward the bottom of a substantially cylindrical shape without a ceiling for accommodating the explosive explosive 2. The explosive fireworks containing explosive housing member 1 has a tapered surface 3a in which the cardboard container is reduced in diameter downward, an annular support portion 3b extending inward from the bottom surface, and a notch 5 for guiding the ignition conductor 4. The launch flying object 6 is placed on the upper surface 3c of the cardboard container.

  The firing gunpowder 2 is accommodated in the bag 7, and the ignition conductor 4 and the launcher 8 of the launch vehicle 6 are inserted into the projecting gunpowder 2.

  The explosive fireworks containing explosive housing member 1 is formed by inserting and bonding both ends of a strip 100 made of fan-shaped cardboard and press-molding. The band plate 100 has a notch 5 formed on the outer peripheral surface 100 a, an insertion port 102 is provided at a predetermined distance from the right end portion 101, and an insertion portion 104 projects from the left end portion 103. In order to form the explosive fireworks containing explosive housing member 1 from the band plate 100, first, the insertion portion 103 is inserted into the insertion port 102 and glued. At this time, the coupling line 105 appears on the surface (see FIGS. 1 and 2). Next, when this is put into the lower mold and pressed with the upper mold from above, the explosive storage member 1 for launching fireworks is formed.

  As shown in FIG. 4, in the explosive fireworks launching explosive accommodating member 1, the launching explosive 2 is placed on the tapered surface 3a and the annular support portion 3b, and the launching flying object 6 is placed on the upper surface 3c. The explosive fireworks containing explosive housing member 1 is coupled with tape 9 or the like. The launch flying object 6 with the explosive fireworks launching explosive housing member 1 combined in this way is accommodated in the launch cylinder 12. Since the launch vehicle 6 can be set in the launch cylinder 12 in this way, the work on site can be largely omitted, and a great contribution can be made to labor saving. Furthermore, since ignition control is often performed by computer control, it is possible to respond quickly.

  As a modification of the embodiment of the present invention, as shown in FIGS. 6 and 7, it is more preferable to provide a plurality of vents 3d ′ on the tapered surface 3a ′ of the substantially cylindrical cardboard container.

  According to the above-described embodiment, by using the explosive fireworks launching explosive housing member 1 to launch the fireworks that are the launching flying bodies 6, there is no work time such as filling the launching explosive 2 at the launch site, Or it is shortened, the assembly of a launching fireworks becomes easy, and the cost as the whole launching fireworks can also be reduced. The explosive fireworks launching explosive housing member 1 has a shape and size that are kept to a minimum, so that less dust is generated. Because it is cardboard, it has less environmental impact. The explosive container 1 for launching fireworks is made of cardboard, and is manufactured simply by inserting and pressing the insertion portion 104 in which the strip 100 is rounded and glued to the insertion slot 102, so the manufacturing process is simple. Yes, it can be produced at a very low cost while maintaining the required strength. The tape 9 is easily pasted by the taper surface 3a of the explosive fireworks launching explosive accommodating member 1, and the assembly work is also easy. Moreover, since the annular support portion 3b is provided, the bag 7 containing the gunpowder 2 is difficult to be removed, and the stability of the gunpowder 2 and the launch vehicle 6 is excellent in terms of storage. Furthermore, the explosive fireworks launching explosive accommodating member 1 is formed with a bottom at the center, so that it is possible to directly open the injection of the firing explosive 2 by ignition and the launch height is not lost.

  Also, in storing and assembling work of the explosive fireworks launching explosive accommodating member 1 and the projectile explosive explosive 2, by having the tapered surface 3a, a plurality of launch fireworks explosive explosive containing members 1 can be stacked vertically. , Storage space is drastically reduced. In general, when assembling launch fireworks, there are many work in the summer, fireworks contractors are very busy, and simple straight bottomed paper tubes are filled with explosives etc. Then, since, for example, 1000 or more pieces are packed in a large box, a space is taken up, the work is very difficult to perform, and there is a problem in management, which is advantageous compared to a case where a vertical paper tube is used. Further, the explosive gunpowder 2 and the launch vehicle 6 are accommodated in the launch tube 12 by temporarily storing the gunpowder 2 and the launch vehicle 6 in a state of being placed on the launcher pyrotechnic gunpowder storage member 1. However, the degree of freedom and convenience of the mounting work is increased, such as the bulky launch tube 12 being able to be stored on its side, and the work efficiency is increased by the progress of the mounting work.

  Further, even during or after moving to the launch site, the gunpowder 2 is difficult to dissipate because it is housed in the bag 7, and even if there is vibration or the like, depending on the shape of the gunpowder housing member 1 for launching fireworks, It becomes difficult for the ignition conducting wire 4 and the conducting wire 8 to shift, improving workability and safety, and facilitating management.

  When a plurality of vents 3d 'are provided on the tapered surface 3a' of the substantially cylindrical cardboard container, an oxygen supply path necessary for the combustion of the explosive 2 is ensured. The launch height deficiency of the launch vehicle 6 due to incomplete combustion can be resolved.

  The embodiments of the present invention are not limited to the following embodiments, and modifications and the like can be made without departing from the technical idea of the present invention. Equivalents and the like are also included in the technical scope of the present invention, and it is needless to say that various forms can be adopted as long as they belong to the technical scope.
