Description

[Detailed Description of the Invention] The present invention relates to crackers used for celebrations such as birthdays and weddings.

Traditionally, this type of cracker (a type of firecracker) is made by pulling a string attached to a trigger ball and using the same cracker, and after the tape etc. is blown out by the blast, it is shaped like an inverted conical cylinder without any decoration remaining. The inside of the outer cylinder of the cracker was exposed, making it unfit and ungainly, and the cracker was of no use after use.

The present invention was developed in view of these circumstances, and the cracker can be used as a type of decoration by allowing a flower-shaped object to protrude from the upper opening of the outer cylinder even after the cracker is used. It is an object of the present invention to provide a cracker which has a good appearance, and which does not expose the inside of the outer cylinder after use due to the protrusion of the shaped body.

Therefore, in the present invention, a trigger ball 5 is disposed on the inner surface of the bottom of an outer cylinder having an inverted conical shape, and an igniting string provided in the trigger ball is led out from a small hole at the lower end of the outer cylinder, and the above-mentioned protective A lid body for preventing the spread of fire is disposed in the upper opening of the inner cylinder, and a projectable shaped object made of thin paper or the like is attached to the upper part of the opening of the outer cylinder, and A plurality of paper tapes are placed in the surplus space in the upper area of the outer cylinder above the molded object, and thin paper is stretched over the upper end opening of the outer cylinder. By providing a ventilation gap for circulation and forming a shape that expands to include the wind, it is an attempt to achieve the above-mentioned intended purpose.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Figure 1 is a cross-sectional view of the cracker according to the present invention, in which:
Reference numeral 1 denotes an outer cylinder in the shape of an inverted conical cylinder, and this outer cylinder 1 is formed by shaping cardboard into an inverted conical cylinder shape, and has a small hole 2 formed at its lowermost end.

Inside the outer cylinder 1, an inner cylinder 3 having the same shape as the outer cylinder 1 and an inverted conical cylinder is disposed.

Like the outer cylinder 1, this inner cylinder 3 is also made of cardboard in the shape of an inverted conical cylinder to prevent danger in the event of an explosion.

A protective inner cylinder 4 made of plastic is disposed on the inner surface of the bottom of the inner cylinder 3, and a pull ball 5 is disposed inside the protective inner cylinder 4.

The trigger ball 5 has a thick cylindrical shape, and is equipped with gunpowder 6 and a string 7 for ignition.

As the gunpowder 6, for example, a well-known mixture of 65% by weight of potassium chlorate, 3% of antimony trisulfide, and 2% by weight of red phosphorus was used, and a portion of it was buried in the gunpowder 6. The thread 7 is led out from the small hole 2, and the gunpowder 6 is ignited by the friction generated when the thread 7 is pulled.

Further, a circular, more specifically disc-shaped lid 8 made of pole paper is disposed at the upper opening of the protective inner cylinder 4.

This lid body 8 is for preventing the spread of fire, which prevents the fire from igniting other members when the gunpowder 6 is ignited.

Connecting tapes 9 are attached at multiple locations in the upper internal area of the outer cylinder.
The shaped body 10 is attached via...

This shaped body 10 is made of thin paper or a synthetic resin sheet processed into a thank-you note, and is attached to the outer cylinder 1 so as to be able to protrude therefrom.

In other words, it can be housed in the outer cylinder 1 as shown in FIG. 1, and can also be protruded from the opening of the outer cylinder 1 as shown in FIG. 3 by the blast wave described later.

Furthermore, the shaped body 10 is provided with a ventilation gap 10a (see FIG. 3) that allows the blast generated when the gunpowder 6 is ignited to flow through the excess space 11 above the shaped body 10, and expands to include the wind. It has such a powerful structure.

Furthermore, red, yellow, green, white, blue, etc. paper tapes 12 are placed in the surplus space 11 above the outer cylinder 1 above the shaped body 10.

These plurality of paper tapes 12 are placed on top of the patterned body 10 in a rolled state, and only the end portions of the rolled paper tapes 12 are slightly tangled as shown in FIG.

It is of course possible to store parachutes, flags, etc. in addition to the paper tape 12 in the surplus space 11.

Further, the upper opening of the outer cylinder 1 is covered with a thin paper 13 that can be torn by blast waves.

Next, the action of the cracker constructed as described above will be described. Now, when holding the outer cylinder 1 of the cracker in one hand and pulling the thread 7 downward in FIG. 1 with the other hand, the gunpowder 6 is released.
The same gunpowder 6 explodes.

The thin paper 13 is blown away by the blast wave from the explosion, and at the same time, the plurality of paper tapes 12 in the surplus space 11 are scattered outward as shown in FIG. As shown in FIG. 3, a flower pattern is formed at the upper opening of the outer cylinder 1.

As explained above with reference to the embodiments, the present invention includes attaching a projectable shaped body 10 made of thin paper into a thank-you note to the upper part of the inner part of the outer cylinder 1, and attaching the shaped body 10 to the upper part of the opening of the outer cylinder 1. It has a ventilation effect 10a that allows the blast wave to flow upward,
In addition, since it has a shape that expands when the cracker is used, the blast wave can cause the shaped body 10 to protrude into the upper end opening of the outer cylinder 1 and expand, and as a result, after using the cracker, Also, the cracker can be used as a toy for children or as a type of decoration.

Furthermore, since the protrusion of the shaped body 10 prevents the inside of the outer cylinder 1 from being completely exposed after use, the appearance is also good.
