Description of the Related Art As is well known, a cylindrical fireworks for a toy that emits sparks and sparks from a cylindrical body set on the ground, or a cylindrical fireworks for a toy such as a launch firework is a cylindrical paper tube having a diameter of several centimeters. A bottom stopper (plug) is formed near the bottom end of the bottom with cement, soil or other irregular refractory material, and the bottom stopper is filled with explosives such as launch balls and propellant, and a squib penetrates the side of the paper tube. When the explosive is ignited by the squib, the powder or the like is blown out or a launch ball is fired. When the gunpowder is ignited in this way, a large load is applied to the bottom stopper as a reaction force of its ejection force. For this reason, it has been necessary to fill the soil or cement with a considerable thickness so that the bottom stopper can have the strength not to be destroyed even under such a load.

るなどの問題もあった。However, as described above, the manufacturing process of forming the bottom stopper in the paper tube is troublesome, and it takes time such as drying at least one day and night. Since the product becomes heavy, it is not easy to handle and transport, and when vibration is applied, the soil etc. may break apart and come out, so it seems that the explosive powder spilled out. There was also a problem that it could be mistaken for.

る。A plastic molded plug replacing the bottom stopper made of the irregular refractory can be easily fixed in the paper tube in a short time. Further, the molded plug has a circular plate portion as described above. It is composed of a skirt portion and is inserted into the paper tube so that the circular plate portion faces upward. Therefore, when a large downward pressure is applied to the circular plate portion due to the explosion of explosive, the circular plate portion The skirt is deformed so as to be expanded further outward, and the adhesion with the inner surface of the paper tube is enhanced. For this reason, it functions as a very strong bottom stop, and there is no risk of falling off, improving safety. In addition, since it is formed of plastic in a hollow shape, it is lightweight and strong against vibration.

外周には複数本の縦溝1cが形成されている。An embodiment of the present invention will be described with reference to the drawings.
In the figure, 1 is a molded plug made of plastic, and the molded plug 1 has a cap-like shape in which a skirt portion 1b is integrally formed on the outer peripheral edge of a circular plate portion 1a so as to hang down. The upper half of the skirt portion 1b has a loose taper shape and a plurality of vertical grooves 1c are formed on the outer periphery thereof.

外部に突出させる。When inserting the molding plug 1 into the paper tube 2, an adhesive is applied to the outer periphery of the molding plug 1 so that the circular plate portion 1a of the molding plug 1 faces upward. Insert this from the bottom edge. Then, the explosive 3 and the squib 4 are arranged on the molding plug 1, and the tip of the squib 4 is projected from the side surface of the paper tube 2 to the outside.

Further, since the vertical groove 1c is formed, the adhesive is retained also in the vertical groove 1c so that the adhesive property is further improved.

おそれはなく、玩具用花火の安全性を向上させる。In the tubular fireworks for a toy configured as described above,
The bottom stopper can be simply and quickly set by inserting the molding plug 1 into the paper tube 2 and drying the adhesive, and the skirt portion of the outer peripheral edge of the circular plate portion 1a is positioned so that the circular plate portion 1a is located above. 1
Since b is adhered to the inner surface of the paper tube 2, the skirt portion 1b is expanded and strongly pressed against the inner surface of the paper tube 2 even if a strong pressure is applied to the circular plate portion 1a due to the explosive charge. Since the state of being firmly fixed inside 2 is maintained, there is no fear that the molding plug 1 will come out of the lower end of the paper tube 2 even if a large load is applied, and the safety of the toy fireworks is improved.
