Description

[Detailed description of the invention] This invention relates to a flowering kratzker that houses artificial flowers that bloom by exploding.

Conventionally, there have been known kratsuka in which a gunpowder body is detonated by pulling a drawstring, and the explosive force causes paper tape, etc. stored in the cylinder to be ejected and spread forward. The explosion debris of the gunpowder body is scattered. In other words, the gunpowder body is usually made by wrapping a small amount of gunpowder in paper so that it rubs against the drawstring, so when it is detonated, the finely blown up paper waste is scattered into the cylindrical body. It was not suitable for use in places where jutan was spread, as it ejected from the lid opening together with the tape and was scattered on the floor.

This idea was created in view of the above circumstances, and focused on the highly interesting Kratzker, in which the artificial flower opens at the opening at the front end of the cylinder when in use. To provide a flowering cracker which suppresses explosive debris of a gunpowder body with its leaf part and prevents it from scattering outward.

The artificial flowers mentioned above are those made only from petals,
It refers to artificial flowers in a broad sense, including those made only from branches and leaves, and those with flowers attached to the leaves. Therefore, flowering as used in this specification also includes the opening of petals, the opening of branches and leaves, and the opening of leaves and flowers. It includes opening, etc.

In order to achieve the above-mentioned purpose, the flowering cracker of this invention is provided with a closing lid that is opened by explosive force at the front end of the cylinder, and from the rear end of the cylinder there is a closing lid that opens outward from the rear end of the cylinder. A gunpowder body that is detonated by pulling a pull cord extending from the cylinder body is held, and a gunpowder body is held in the cylinder body located between the gunpowder body holding part and the cylinder body closing lid, and the explosion occurs at the cylinder body opening part. An artificial flower that can close the opening of the cylinder in its blooming state is compressed into a small size so as to function as an explosion pressure plate, and the artificial flower is inserted into the cylinder with a connecting string of a certain length. The artificial flower is stopped at the position of the opening part of the cylindrical body and opens at the time of explosion, and the petals or leaves of the artificial flower opened at the opening part of the cylindrical body are used to detonate explosive debris from the gunpowder body. This feature is characterized in that it holds down the particles and prevents them from scattering outward.

An embodiment of this invention will be described below with reference to the drawings. In the drawing, 1 is a pyramid-shaped cylinder made of cardboard, and a closing lid 2 is attached to the front end of the cylinder, which opens with explosive force.
is provided. In the case of this embodiment, this cylindrical body closing lid 2 is composed of a flap assembly lid in which five cylindrical corner side flaps 2a to 2e are bent and assembled as shown in FIG. It may also be a separate closure lid that is explosively and removably fitted into the opening.
3 is a cylindrical cylinder inserted and fixed into the cylindrical body 1;
A gunpowder holding plate 4 is fixed at a longitudinally intermediate position within the cylinder body 1. 5 is a known explosive body made by wrapping a small amount of explosive in paper so that it rubs against the drawstring 6;
It is designed to be exploded by pulling the drawstring 6 in a state where it is in contact as shown in FIG. 2. The drawstring 6 is passed through the center hole 4a of the gunpowder holding plate 4 and extends outward from the rear end opening of the cylinder 1. Reference numeral 7 denotes an artificial flower having the function of an explosion pressure receiving plate, which is compressed and fitted into the cylindrical interior 8 between the gunpowder holding plate 4 and the closing lid 2; in this embodiment, the cylindrical body 1 A plurality of leaves 7a made of cloth that open as shown in Fig. 3 so as to cover the opening part of the
Then, in a flowering state consisting of several flexible flower stems 7b extending from the central joint of the several leaves 7a and cloth flowers 7c attached to the tips of each flower stem, open the cylindrical lid opening. It is constructed as an art flower that can be closed, but as long as it is an artificial flower that can close the opening of the cylinder in the flowering state, even if it is made with only a large number of petals like an artificial carnation flower. You can also use artificial flowers made from only branches and leaves. Reference numeral 9 denotes a connecting string-like object of a certain length that is connected to the inside of the cylinder 1 so that the artificial flower 7 blooms at the opening of the cylinder 1 as shown in FIG. A thin wire containing a bent or extensible wire may be used, or a string-like material such as a thread bound to the artificial flower 7 may be used. In this embodiment, the connecting string-like object 9 is fixed to the cylindrical body 1 by fixing the end of the string-like object 9 to the adhesive tape 10.
exemplifies the method of adhesively fixing it to the inner wall of the cylinder 3, but if the connecting string-like object 9 is the thin wire containing the wire described above, the end of the thin wire may be bent into a hook shape. It is also possible to adopt a method of latching it to a notch or the like in the cylinder 3, or if the string-like object 9 is a thread or the like, the gunpowder holding plate 4 is provided with a string attachment part such as a protrusion or a hole. A method of fixing the end of the string-like material 9 here may also be considered. Furthermore, as another fixing method, the string-like object 9 may be extended from the rear end of the cylinder 1, and this extended end may be fixed to the outer surface of the rear end of the cylinder 1 using adhesive tape or the like. is also possible. In short, in the connecting string-like object 9, the artificial flower 7 is connected to the cylinder 1.
The method of fixing the end of the string is limited to the gist of this invention, since it is sufficient to hold the artificial flower 7 at the position of the opening part of the cylinder body when the Kratzker explodes, so that the artificial flower 7 opens at the opening part of the cylinder body. isn't it.

The flowering cracker of this invention has the above-mentioned artificial flower storage structure, so when the gunpowder body is exploded by pulling the drawstring, the explosive force opens the cylindrical body closing lid and the artificial flowers are released. Since the flower pops out to the opening of the cylinder and blooms as shown in Figure 3, it is more beautiful than the conventional tape-spout type. The leaves (for example, the leaf part) close the opening of the cylinder body in a flowering state, which prevents the explosion debris of the gunpowder body from spewing out and scattering to the outside, providing a cracker suitable for use at wedding halls, etc. can do. In addition, since the artificial flower has the function of an explosion pressure receiving plate when it is compressed and fitted into the interior of the cylinder, the explosion pressure receiving plate, which is essential in conventional crackers, can be eliminated and the structure can be simplified. .
