Description

A firecracker for party {A cracker for party}

The present invention mainly relates to firecrackers used in celebrations, and more particularly, to party firecrackers used to create a more dramatic and colorful atmosphere of celebration in various celebrations such as birthdays, weddings or various anniversaries.

Recently, with the economic growth, the atmosphere to pursue leisure time is gradually spreading socially, and accordingly, various party events and event cultures are becoming popular.

Particularly, firecrackers, which are used for events such as birthdays and weddings, are used when the atmosphere of a celebration is at its peak, and colored confetti, which is sewn together with binge drinking, emits the atmosphere of the event hall. It plays an important role in dramatizing and splendidly.

Such a conventional firecracker 10 is composed of a large case 20 and a lid 30, as shown in Figure 1a and 1b, first, the cone-shaped case 20 has a triangular cross section on the top An annular locking jaw 21 having a shape is formed along the inner circumferential surface thereof.

And right below the locking jaw 21 is an annular fitting groove 22 having a jaw is formed along the inner circumferential surface of the case 20. Although not shown, a small amount of gunpowder is filled on the inner bottom of the case 20, and colored paper tape or gold foil or silver foil paper of various colors is filled thereon.

The disc-shaped lid 30 is fitted into the annular fitting groove 22 formed in the case 20. The assembly process of such a lid 30 will be described in detail with reference to FIG. 1B, for the assembly of the lid 30. 30 is forcibly pushed into the case 20. At this time, the lid 30 passes through the locking jaw 21 while slightly bending to its own elastic force, and reaches the annular fitting groove 22 formed just below the locking jaw 21, and then restores the shape by the elastic restoring force. While being hooked to the annular fitting groove 22 as described above.

On the other hand, the lower end of the case 20, the ignition string (R) is drawn out, one end of the ignition string (R) is connected to the gunpowder filled in the case 20, the other end is the adhesive tape (T) And the like on the outer surface of the case 20.

On the other hand, Figure 2 shows another conventional firecracker 10, the structure and function is the same as the firecracker 10 shown in Figure 1a except that the case 20 is formed in a cylindrical shape.

The conventional firecracker 10 configured as described above pulls the ignition string R from the adhesive tape T and pulls the lid 30 together with the explosion sound due to the instantaneous explosive power generated by the gunpowder inside the case 20. ) Is separated from the case 20, so that the paper tape is ejected out of the case 20 at once to enhance the atmosphere of the celebration event venue.

However, the conventional party firecracker 10 has a problem in that the case 20 and the lid 30 are produced by each mold separately, so that expensive mold costs are consumed and production costs are increased.

In addition, the conventional party firecracker 10 has a problem in that the production of the firecrackers is reduced because a lot of work process and work touch is required in this process because the assembly method to fit the lid 30 to the case 20 one by one.

That is, when the cap 30 is inserted in the inclined state or crumpled in the case 20 as described above, when a gap is generated, the ejection pressure due to the explosive force of the explosive power during ignition leaks through the gap in some cases ( 20) There was a problem that the paper tape inside can not go far. In addition, since the explosion pressure is dispersed due to the gap between the lid 30 and the case 20 described above, there is a problem that the lid 30 cannot be opened.

Furthermore, during the storage of the firecracker 10, moisture in the air flows through the gap between the case 20 and the lid 30, so that the gunpowder inside the case 20 absorbs moisture. Therefore, since the ignition is not well made, there is a problem that the firing success rate of the firecracker 10 is significantly lowered.

And since the annular fitting groove 22 into which the lid 30 is fitted is narrow in width, when the lid 30 is assembled to the case 20, the lid 30 is annular fitting groove 22 when a force is applied to the lid 30. The problem of falling down easily occurred. Therefore, it is very difficult to maintain a constant coupling force of the lid 30 and the case 20 for each product, the quality is uneven, there is a problem that the explosion sound accordingly appears differently.

The present invention has been made to solve the conventional problems as described above, an object of the present invention is to provide a party firecracker that can be easily assembled to the lid because the lid and the case integrally formed.

In addition, another object of the present invention is to connect the lid and the case integrally, the lid is assembled with a constant coupling force to the case, thereby improving the sealing force of the case to provide a party firecracker that can generate a certain explosion sound.

And another object of the present invention is to provide a party firecracker that can be stably coupled to the case without the lid is wrinkled to block the moisture inflow from the outside to improve the ignition performance of the firecracker.
