Abstract

(57) [Summary] [Problem] To provide a fireworks with a novelty suitable for a new era by devising a basic material which is the same as a conventionally known one, but devising a constituent material and a combination thereof. SOLUTION: A cylindrical body filled with a burning agent is made of a transparent material, the burning agent is colored, and the color of the burning agent is made visible from the outside through the cylindrical body. Further, the cylinder filled with the burning agent is constituted by an acetylene pipe, and is burned together with the burning agent.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to fireworks for toys.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, there has been known a fireworks in which a burning agent mainly composed of an explosive charged in a cardboard cylinder is ignited and burned, and a spark is ejected from the tip of the cylinder to enjoy the fireworks.

[0003]

[Problems to be solved by the invention]

 The above-mentioned fireworks have a long history, and the old-fashioned fireworks are already out of date. Their lack of surprisingness has led to their production stagnating without popularity and falling year by year.

The purpose of the present invention is to provide a fireworks with a novelty suitable for a new era by devising the constituent materials and their combinations, although the basic structure is the same as the conventionally known ones. It is in.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is characterized in that a cylinder filled with a burning agent is made of a transparent material, and the burning agent is colored.

[0006] The present invention is also characterized in that it includes a transparent cylinder, a colored combustion agent filled in the interior of the cylinder, and a hand-held portion connected in the axial direction of the cylinder.

[0007] The present invention further includes a combustion cylinder made of a transparent acetylene pipe, a colored combustion agent filled inside the cylinder, and a hand-held portion connected in the axial direction of the cylinder. It is characterized by.

In this case, according to the present invention, the holding portion can be made of a synthetic resin.

According to the present invention, it is possible to make the flame color when the combustible burns and the color of the combustible visible through the transparent cylinder or the combustion cylinder substantially.

[0010]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a transparent cylinder which can be seen through, 2 denotes a combustion agent filled in the interior of the cylinder, and 3 denotes a hand-held portion connected to the end of the cylinder 1 in the axial direction. The cylinder 1 does not necessarily need to be burned together with the combustion agent 2, but the embodiment is a transparent acetylene pipe designated as No. 201. In this case, since the cylinder 1 is burned together with the combustion agent 2 at the same burning rate by ignition, such a cylinder is particularly referred to as a combustion cylinder in this specification. However, it does not necessarily need to be made of a material that burns together with the combustion agent. In such a case, this is called a cylinder. The material of the cylinder 1 is not limited as long as it is transparent and safe.

[0011] The burning agent 2 includes an oxidizing agent (potassium nitrate, potassium perchlorate, ammonium perchlorate, etc.), an auxiliary agent (wood flour, sulfur, charcoal, vinsol, resin, etc.), and a sparking agent (aluminum, Magnesium, titanium, etc.), and all or some of the above drugs are appropriately selected and used in combination. According to the invention, wood flour is dyed in a color such as red, blue or yellow and mixed with the above-mentioned other chemicals, so that the entire combustible displays a specific color. The cylinder 1 can be seen through from the outside of the transparent cylinder 1 (combustion cylinder). A method for producing colored wood flour is, for example, to color both pigment and wood chips by putting them in water, take out and dry them, and then pulverize them finely. Amount. When implemented in this manner, the entire color of the combustion agent 2 becomes a pale pastel color. In this case, the flame color of the burned combustion agent should be the same color as the colored color of the combustion agent or the color of the combustion material seen through the cylinder. Can be. In this case, a further coloring agent would be added to the combustion agent 2. Known strontium (red), sodium (yellow), barium (green), copper (blue) and the like are known as the color-explosive.

An ignition material 4 is filled and fixed to the tip of the cylinder 1, and a combustion stopper 5 such as cement is filled and fixed to the rear end of the cylinder 1.

The hand-held part 3 is a PVC pipe in the embodiment, but is not limited to this, and may be made of another synthetic resin such as polypropylene, or a paper pipe. The material is not limited. The hand-held portion 3 may be made of the same material as the cylinder 1 (combustion cylinder). In the case where an acetylene pipe is used for the cylinder 1 (combustion cylinder), if the same material is used for the holding section 3, there is a problem that the manufacturing cost is high. Is made of an inexpensive material such as a PVC pipe.

[0014] Even if an acetylene pipe is used up to the hand holding portion, the combustion stops by the combustion stop, so that the fire does not transfer to the hand holding portion and the fire is naturally extinguished at the combustion stop portion. This is the same even if the hand-held part is made of a paper cylinder or other synthetic resin.

It is optional to apply coloring directly to the hand-held portion, or to wind a colored thin paper or other synthetic resin film.

[0016]

[Effect of the invention]

 Since the present invention is configured as described above, the following operational effects can be obtained.

According to the first aspect of the present invention, the inside of the cylindrical body can be seen from the outside of the tubular combustion agent, and the combustion state can be seen. .

According to the second aspect of the invention, when the cylinder is made of an expensive material such as an acetylene pipe while providing the same operation and effect as the first aspect, the handle can be made inexpensive. By using the material, it is possible to produce an effect that the whole can be manufactured at low cost.

According to the third aspect of the invention, the same effects as those of the first and second aspects can be obtained, and the combustion cylinder made of an acetylene pipe can be burned at the same speed as the combustion agent. The surprisingness that is not contained in a cylinder that does not burn together and is not filled with a burning agent so that it cannot be seen from the outside can have the effect of further delighting the interest.

According to the present invention, even if an effective material such as an acetylene pipe is used for the combustion cylinder, an inexpensive agent is used for the hand-held part, thereby reducing the manufacturing cost as a whole. The effect that can be performed can be produced.

According to the fifth aspect of the present invention, the same flame is emitted as the combustion agent visible from the outside of the cylinder (combustion cylinder), and the combustion agent is burned. Can be played.
