It can be. An optional connecting member 230 may be a member that connects the outer tubular member 220 to a certain tubular member 210.

(2-1) A certain cylindrical member 210
FIG. 6(a) is a side view showing an example of the configuration of a certain cylindrical member 210 included in the support member 200 shown in FIG. 210 is a front view showing an example of the configuration of 210. FIG.

In one example, a certain cylindrical member 210 may include two cylindrical members that are coupled to each other, that is, a first cylindrical member 210A and a second cylindrical member 210B that are coupled to each other. can.

The first cylindrical member 210A may be a member that accommodates and supports one end 102 of the rod-shaped member 100. The second cylindrical member 210B may be a member that accommodates and supports an explosive product, which will be described later.

For example, the first cylindrical member 210A may have a substantially cylindrical shape (substantially circular cross-sectional shape) as shown in FIG. (can have an outer diameter of about 7.7 mm, an inner diameter of about 6 mm, and a length of about 15 mm). In another example, the first cylindrical member 210A has an arbitrary cross-sectional shape including a substantially elliptical shape, a substantially rectangular shape, and/or a substantially polygonal shape, depending on the shape of the rod-like member 100, although not shown. You can also do that.

The first cylindrical member 210A includes an opening 216A that communicates with the outside of the first cylindrical member 210A at one end 212A, and communicates with the inside of the second cylindrical member 210B at the other end 214A. An opening 218A may be included. The opening 216A and/or the opening 218A may have any shape including a circular shape, an elliptical shape, a rectangular shape, a polygonal shape, and the like.

The first cylindrical member 210A receives one end 102 of the rod-like member 100 from the opening 216A, and can accommodate the one end 102 of the rod-like member 100 inside the first cylindrical member 210A. Furthermore, the first cylindrical member 210A can be coupled to the rod-shaped member 100 with the tip of one end 102 disposed at or near the opening 218. For example, the first cylindrical member 210A may be coupled to one end 102 of the rod-like member 100 by at least one caulking from the outer surface of the first cylindrical member 210A toward its central axis.

The first cylindrical member 210A may be formed of a material such as metal, a heat-resistant resin, or a heat-resistant carbon fiber, or a material obtained from any combination of these materials.

On the other hand, the second cylindrical member 210B can have a substantially cylindrical shape, for example, as shown in FIG. (can have an inner diameter of about 7.3 mm and a length of about 23.7 mm). In another example, although not shown, the second cylindrical member 210B may have any cross-sectional shape including a substantially elliptical shape, a substantially rectangular shape, and/or a substantially polygonal shape in accordance with the shape of an explosive product to be described later. It can also be presented.

The second cylindrical member 210B includes an opening 216B that communicates with the inside (opening 218A) of the first cylindrical member 210A at one end 212B, and the other end 214B includes an opening 216B that communicates with the inside of the first cylindrical member 210A (opening 218A). It can include an opening 218B that communicates with the outside. The opening 216B and/or the opening 218B may have any shape including a circular shape, an elliptical shape, a rectangular shape, a polygonal shape, or the like. Also, in one example, opening 216B can have substantially the same shape as opening 218A, but in another example, opening 216B can be smaller or larger than opening 218A.

The second cylindrical member 210B extends along the opening 216B, and extends in a direction intersecting the extending direction (left-right direction on the page) of the second cylindrical member 210B, for example, in a direction perpendicular to this extending direction. It may also include an extending, annular abutment surface 219B.

The second cylindrical member 210B receives one end 402 of an explosive product, which will be described later, through the opening 218B, and can house the one end 402 of the explosive product inside the second cylindrical member 210B. Additionally, the second cylindrical member 210B holds the one end 402 of the explosive product (usually by user operation) until the wall 406 formed in the one end 402 of the explosive product is disposed at or near the opening 216B. ) can be accepted by sliding. In one example, the second tubular member 210B can be slid to receive one end 402 of the explosive product (usually by user manipulation) until the wall 406 of the explosive product abuts the abutment surface 219B. can. Thereby, the second cylindrical member 210B can accommodate and support the explosive product.

The second cylindrical member 210B may be formed of a material such as metal, a heat-resistant resin, or a heat-resistant carbon fiber, or a material obtained from any combination of these materials.

Note that, as an option, at least one second cylindrical member 210B (example in FIG. In this case, one notch 210a can be included. When a plurality of notches 210a are provided, the plurality of notches 210a may be arranged at a distance along the circumferential direction of the second cylindrical member 210B.

Such a notch 210a has one end surface 210b surrounding this notch 210a and another end surface 210c opposite to this end surface 210b when the second cylindrical member 210B receives one end 402 of an explosive product to be described later. It is possible to allow an increase in the distance between the end surfaces 210b and 210c (increase in the distance between the end surfaces 210b and 210c). The second cylindrical member 210B, which has once increased the distance between the end surface 210b and the end surface 210c in this way, returns to the original distance between the end surface 210b and the end surface 210c in order to return to its original shape. In addition, the end surface 210b and the end surface 210c can be biased toward each other. Thereby, the second cylindrical member 210B can always exert a force on the explosive product to pinch one end 402 of the explosive product. As a result, the degree of close contact between the second cylindrical member 210B and the one end 402 of the explosive product increases, and the frictional force between them increases, so that the second cylindrical member 210B can be held (supported) without damaging it.

For example, when using the notch 210a having a width of about 2 mm (distance between the end surface 210b and the end surface 210c) and a length of about 20 mm, the second cylindrical member 210B is smaller than the outer diameter of the one end 402 of the explosive product. By having a small inner diameter (eg about 0.3 mm) this effect can be further enhanced.

In addition, in the example shown in FIG. 6, the notch 210a, for example, extends along the extending direction (longitudinal direction) of the second cylindrical member 210B, and covers most of the entire length of the second cylindrical member 210B. It is formed over a period of time. The length of the notch 210a can be appropriately set depending on the amount of force required to pinch one end 402 of the explosive product. For example, as the notch 210a is made longer, the distance between the end surface 210b and the end surface 210c becomes longer when the one end 402 of the explosive product is received, so that the second cylindrical member 210B holds the one end 402 of the explosive product becomes larger.

In addition, as another option, the second cylindrical member 210B may be arranged such that the outer surface and the inner surface of the second cylindrical member 210B (i.e., the second At least one first air hole 212a (three air holes 212a 1 , 212a ₂ , 212a ₃ in the example shown in FIG. 6) communicates with the outer surface of the explosive product housed in the cylindrical member _210B . can be included. When a plurality of first air holes 212a are provided, the plurality of first air holes 212a may be arranged at a distance along the circumferential direction of the second cylindrical member 210B. In an example in which three first air holes 212a are provided, as clearly shown in FIG. 5, these three first air holes 212a are arranged at equal intervals along the circumferential direction of the second cylindrical member 210B. It can be placed at Each of the first air holes 212a can have a diameter of about 2 mm, for example.

Such a first air hole 212a extends from the outside to the inside of the second cylindrical member 210B (particularly toward the tip of one end 402 of the explosive product housed in the second cylindrical member 210B). ) can function to allow air to pass through. Since the gunpowder product is combusted toward the tip of one end 402 of the gunpowder product, the tip of the one end 402 of the gunpowder product is most likely to remain unburned. In view of this, the first air hole 212a is provided at a position adjacent to the contact surface 219B or near the contact surface 219B, thereby supplying air to the tip portion that is most likely to remain unburned. As a result, combustion can be promoted particularly at the tip.

In order to promote combustion of the tip of the one end 402 of the explosive product, the first air hole 212a is preferably arranged closer to the one end 212B of the second cylindrical member 210B. In addition to or in place of this, the first air hole 212a may be inserted into any part of the second cylindrical member 210B (e.g. , near the other end 214B of the second cylindrical member 210B, and/or between one end 212B and the other end 214B of the second cylindrical member 210B).

Note that the first cylindrical member 210A can also include a wall surface that prevents communication with the inside of the second cylindrical member 210B (opening 216B) instead of the opening 218A at the other end 214A. Alternatively or in addition to this, the second cylindrical member 210B prevents communication with the inside of the first cylindrical member 210A (opening 218A) at one end 212B instead of the opening 216B. It can also include walls that

Furthermore, in the example shown in FIG. 6, the first cylindrical member 210A is formed so that its outer diameter is smaller than the outer diameter of the second cylindrical member 210B. However, the first cylindrical member 210A is designed such that its outer diameter is approximately the same as the outer diameter of the second cylindrical member 210B, or the outer diameter is smaller than the outer diameter of the second cylindrical member 210B. It is also possible to form it so that it becomes large.

(2-2) Outer cylindrical member 220 and connection member 230
7(a) is a side view showing an example of the configuration of the outer cylindrical member 220 and the connecting member 230 included as options in the support member 200 shown in FIG. It is a front view which shows an example of the structure of the outer cylindrical member 220 and the connection member 230 which are included as an option in the support member 200 shown in FIG.

The outer cylindrical member 220 covers the outer surface of a second cylindrical member 210B of a certain cylindrical member 210 (and covers a part of the outer surface of a first cylindrical member 210A of a certain cylindrical member 210). (or it is possible to cover the entire surface), and may be a member that is provided at a distance from the outer surface to form a layer of air between it and the outer surface. By forming such a layer of air, the outer tubular member 220 can absorb the outer tubular member 220 from the explosive product supported by the second tubular member 210B and/or from the second tubular member 210B. Heat conduction to the cylindrical member 220 can be at least partially suppressed. As a result, it is possible to at least partially suppress the outer cylindrical member 220 from reaching a high temperature, so that a situation where a user comes into contact with the outer cylindrical member 220 and suffers a burn injury (when the cover member 300 is provided) This makes it possible to more effectively suppress the situation in which the user contacts the cover member 300 and suffers burns.

For example, the outer cylindrical member 220 can have a substantially cylindrical shape (substantially circular cross-sectional shape) as shown in FIG. an outer diameter of about 17.4 mm, an inner diameter of about 17.4 mm, and a length of about 24.7 mm). In another example, although not shown, the outer cylindrical member 220 may have any cross-sectional shape including a substantially elliptical shape, a substantially rectangular shape, and/or a substantially polygonal shape.

The outer cylindrical member 220 may be formed of a material such as metal, a heat-resistant resin, or a heat-resistant carbon fiber, or a material obtained from any combination of these materials.

The outer cylindrical member 220 includes an opening 226 communicating with the outside of the outer cylindrical member 220 at one end 222 and an opening 226 communicating with the outside of the outer cylindrical member 220 at the other end 224. 228. Opening 226 and/or opening 228 may have any shape, including circular, elliptical, rectangular, polygonal, and the like.

On the other hand, the connecting member 230 has a plate shape and extends in a direction intersecting (orthogonal to in the example shown in FIG. 7) the outer surface of the second cylindrical member 210B of the certain cylindrical members 210. It may be a member that connects the cylindrical member 210 (here, the first cylindrical member 210A) and the outer cylindrical member 220.

The connecting member 230 may be formed of a material such as metal, a heat-resistant resin, or a heat-resistant carbon fiber, or a material obtained from any combination of these materials.

In the example shown in FIG. 7, since each of the first cylindrical member 210A and the outer cylindrical member 220 included in a certain cylindrical member 210 has a substantially cylindrical shape, the first cylindrical member 210A The connecting member 230 that connects the outer cylindrical member 220 and the outer cylindrical member 220 can have an annular shape (can have an inner circumferential surface and an outer circumferential surface).

The connecting member 230 is connected to one end 222 of the outer cylindrical member 220 (an end surface 222a extending in a substantially annular shape surrounding the opening 226 formed in the outer cylindrical member 220) so as to cover the opening 226 of the outer cylindrical member 220. , welding, welding, or the like. Furthermore, the connecting member 230 can be joined by welding, welding, or the like, with its inner circumferential surface abutting the outer circumferential surface of the first cylindrical member 210A. Thereby, the outer cylindrical member 220 can be supported by the connection member 230 and the first cylindrical member 210A.

Optionally, the connecting member 230 has at least one second air hole 236 (eight holes in FIG. 2 air holes 236). When a plurality of second air holes 236 are provided, the plurality of second air holes 236 may be arranged at a distance along the circumferential direction of the connecting member 230. In an example in which six second air holes 236 are provided, these six second air holes 236 may be arranged at equal intervals along the circumferential direction of the connecting member 230.

Such a second air hole 236 is formed from the outside to the inside of the connecting member 230 (in particular, toward the first air hole 212a formed in the second cylindrical member 210B, and in turn, the direction of the gunpowder product. (towards the tip of one end 402). As described above, since the gunpowder product is combusted toward the tip of one end 402 of the gunpowder product, the tip of the one end 402 of the gunpowder product is most likely to remain unburned. In view of this point, the second air hole 236 is provided at a position close to the first air hole 212a or adjacent to the first air hole 212a, so that the second air hole 236 is provided at a tip portion that is most likely to remain unburned. Since air can be supplied, combustion can be promoted particularly to the tip.

Note that part or all of the support member 200 described above may be formed using any method including die molding, a 3D printer, or the like.

(3) Cover member 300
FIG. 8(a) is a side view showing an example of the configuration of a cover member 300 included as an option in the pattern product shown in FIG. FIG. 3 is a front view showing an example of the configuration of a cover member 300 included.

Broadly speaking, the cover member 300 includes a mounting portion 302 that engages with the rod-shaped member 100 and a shielding portion that is coupled to the mounting portion 302 and extends along the outer surface of the outer cylindrical member 220 at a distance from the outer surface. 304.

The attachment portion 302 allows the rod-shaped member 100 to be inserted thereinto, and can come into contact with and surround the outer surface of the rod-shaped member 100. Thereby, the attachment part 302 can attach the cover member 300 to the rod-shaped member 100. The attachment portion 302 has a shape that matches the outer shape of the rod-shaped member 100, so that it can be slidably attached to the rod-shaped member 100. For example, when the rod-like member 100 has a substantially circular cross section (or a substantially rectangular cross-section), the mounting portion 302 has an inner diameter that is slightly larger than the outer diameter of the rod-like member 100 (or a cross section that is slightly larger than the cross section of the rod-like member 100). By being configured to have a large substantially rectangular cross section), it can be slidably attached to the rod-shaped member 100.

The shielding portion 304 can extend at a distance from the outer surface of the outer cylindrical member 220 along the extending direction of the outer cylindrical member 220 (left-right direction on the paper). As clearly shown in FIG. 3, the shielding part 304 can also extend along the entire outer cylindrical member 220 along the extending direction of the outer cylindrical member 220 (left-right direction on the paper). In another example, although not shown in FIG. 3, the shielding portion 304 may extend along a portion of the outer cylindrical member 220 along the direction in which the outer cylindrical member 220 extends.

In the example shown in FIG. 8, the size of the outer cylindrical member 220 along the radial direction is larger than the size of the rod-shaped member 100 along the radial direction. The size is larger than the size of the attachment portion 302 along the radial direction. In this case, the shielding part 304 can be coupled to the attachment part 302 via the communication part 306. The communication portion 306 may be disposed between the attachment portion 302 and the shielding portion 304. The communication portion 306 can have a size that increases as it approaches the shielding portion 304 from the attachment portion 302 (for example, an inner diameter and an outer diameter that increase as it approaches the shielding portion 304 from the attachment portion 302).

In the example shown in FIGS. 8 and 3, the cover member 300 extends from the attachment portion 302 through the communication portion 306 to the shielding portion 304, including the rod-shaped member 100, a certain cylindrical member 210, and the outer cylindrical member 220, respectively. may be formed to extend spirally relative to the outer surface of the . In this case, the cover member 300 may be formed by, for example, bending a single thin rod-shaped member so as to extend in a spiral shape. In this case, for example, the attachment part 302 has an outer diameter of about 8.4 mm and a length of about 12 mm, and the shielding part 304 has an outer diameter of about 25.4 mm and a length of about 29.4 mm. The single thin rod-like member can have an outer diameter of about 1.22 mm. In another example, although not shown, the cover member 300 may have any cross-sectional shape including a substantially elliptical shape, a substantially rectangular shape, and/or a substantially polygonal shape when viewed from a cut plane orthogonal to the extension direction. can.

The cover member 300 is not limited to a spiral shape, and may be formed using other shapes instead of or in addition to the spiral shape. For example, the cover member 300 may be formed in a cylindrical shape. In this case, the attachment portion 302 and the shielding portion 304 are each formed of cylindrical members having mutually different sizes (for example, mutually different inner diameters and outer diameters), and the communication portion 306 connects the attachment portion 302 and the shielding portion 304 with each other. It can be formed by a cylindrical member that connects.

Note that when the cover member 300 is formed in a spiral shape, it is formed to have a lighter mass than when it is formed in a cylindrical shape with no gaps. obtain. Thereby, it is possible to reduce the weight of the cover member 300 and, by extension, the weight of the patterned product 1.

Such a cover member 300 may be made of a material such as metal, a heat-resistant resin, or a heat-resistant carbon fiber, or a heat-resistant natural material (bamboo, wood, etc.), or any combination of these materials. It can be formed from a material that can be used.

Note that the optional outer cylindrical member 220 and cover member 300 do not necessarily need to be provided together, and it is also possible to provide only one of them.

Further, a part or all of the cover member 300 described above may be formed using any method including molding, a 3D printer, or the like.

The cylindrical member 400 can have a cylindrical shape extending from one end 402 to the other end 404. The tubular member 400 can include a wall 406 at one end 402. The wall portion 406 can form an end surface (tip surface) of the cylindrical member 400 (in cooperation with the decorative paper 600 when the decorative paper 600 is used). The wall portion 406 can extend in a direction (for example, a direction substantially perpendicular to the extending direction) that intersects the extending direction of the cylindrical member 400 (left-right direction on the paper).

The tubular member 400 can also include an opening 408 at the other end 404 for receiving the explosive 500.

Further, in one example, the cylindrical member 400 can have a substantially circular cross section when viewed from a cut plane perpendicular to the extending direction (in this case, the cylindrical member 400 has an inner diameter of about 7 mm, for example, (can have an outer diameter of 7.1 mm and a length of about 100 mm to about 250 mm). In another example, the cylindrical member 400 can have any cross-sectional shape including a substantially elliptical shape, a substantially rectangular shape, and/or a substantially polygonal shape when viewed from a cut plane orthogonal to the extending direction.

Such a cylindrical member 400 may be formed of, for example, a flammable material such as paper (cardboard), plastic, or resin, or a material obtained from any combination of these materials.

Note that the cylindrical member 400 can include a sealing material (not shown) at the other end 404 that seals the opening 408 in order to prevent the gunpowder 500 housed therein from jumping out to the outside. . Such sealing material may be formed from a combustible material such as paper or resin.

Moreover, when the decorative paper 600 is used, the cylindrical member 400 includes the decorative paper 600 as a component (the cylindrical member 400 cooperates with the decorative paper 600 to form a cylindrical member). It is possible to understand.

In addition, if the cylindrical member 400 has only enough strength to be significantly damaged when being pushed into the second cylindrical member 210B of the patterned product 1, the inside of the second cylindrical member 210B It may be difficult to reach the formed contact surface 219B. Therefore, it is preferable that the cylindrical member 400 has such strength that it will not be significantly damaged when being pushed into the second cylindrical member 210B of the patterned product 1. The strength of the tubular member 400 can be increased, for example, by increasing the thickness of the material that makes up the tubular member 400.

(1-2) Gunpowder 500
Gunpowder 500 can be accommodated inside cylindrical member 400 through opening 408 . The gunpowder 500 housed inside the cylindrical member 400 can include, for example, a plurality of types of gunpowder (in powder form) that each emit sparks with a unique color, and gunpowder for ignition. Gunpowder for ignition may be placed near the other end 404, and the plurality of types of gunpowder may be placed between the gunpowder for ignition and wall portion 406. As these gunpowder, any gunpowder can be used among the known gunpowder conventionally used in "Sampas grass fireworks".

(1-3) Decorative paper 600
The decorative paper 600 can cover part or all of the cylindrical member 400 in order to decorate the appearance of the product. Decorative paper 600 may include one or more sheets of paper (thin paper) that is a combustible material. The decorative paper 600 may be fixed to the cylindrical member 400 using an adhesive or the like. As described above, the decorative paper 600 can be understood to be a part of the cylindrical member 400 (cooperating with the cylindrical member 400 to form the cylindrical member).

(1-4) Ignition paper 700
The ignition paper 700 is called a "tip" and can be provided for decoration or the like using paper or the like.

Such a gunpowder product 2 is designed so that the user can remove the wall portion 406 formed at one end 402 of the cylindrical member 400 from the second cylindrical member 210B included in a certain cylindrical member 210 of the handle product 1 described above. By pushing the cylindrical member 400 into the second cylindrical member 210B until it abuts the contact surface 219B (see FIG. 6), the cylindrical member 400 is supported by (the second cylindrical member 210B of) the pattern product 1. obtain. Thereby, the gunpowder product 2 can cooperate with the patterned product 1 to form a fireworks product ("Sampas grass fireworks").

In this way, the cylindrical member 400, particularly the one end 402 of the cylindrical member 400, has enough strength to substantially maintain its shape without being significantly damaged even if it is pushed into the second cylindrical member 210B. can have Further, once the cylindrical member 400 is pushed into and supported inside the second cylindrical member 210B, particularly the one end 402 of the cylindrical member 400, the user moves the explosive product 2 away from the second cylindrical member 210B. By pulling it out, it can be removed from the second cylindrical member 210B. Therefore, the gunpowder product 2, that is, the cylindrical member 400, particularly the one end 402 of the cylindrical member, can be detachably attached to the handle product 1 (in other words, the second cylindrical member 210B of the handle product 1 is It can be said that it can be detachably provided at one end 402 of the product 2). This similarly applies when decorative paper 600 is used.

(2) Explosive product 2A according to another embodiment
A specific example of the configuration of an explosive product according to another embodiment will be described with reference to FIG. 10. FIG. 10 is a cross-sectional view schematically showing an example of the configuration of an explosive product according to another embodiment.

The explosive product 2A shown in FIG. 10 can cooperate with the patterned product 1 described above to form a fireworks product called a "sparkler."

As shown in FIG. 10, the explosive product 2A can include a cylindrical member 400A and explosive 500A partially housed inside the cylindrical member 400A. The explosive product 2A can also optionally include a decorative paper 600A that covers a portion of the cylindrical member 400A.

Such an explosive product 2A lacks a handle that can be held by a user.

(2-1) Cylindrical member 400A
The cylindrical member 400A can have a cylindrical shape extending from one end 402A to the other end 404A. The cylindrical member 400A can include a wall 406A at one end 402A. The wall portion 406A can form an end surface (tip surface) of the cylindrical member 400A (in cooperation with the decorative paper 600A when the decorative paper 600A is used). The wall portion 406A can extend in a direction (for example, a direction substantially perpendicular to the extending direction) that intersects the extending direction (horizontal direction on the paper) of the cylindrical member 400A.

The cylindrical member 400A can also include an opening 408A at the other end 404A for receiving the explosive 500A.

Further, in one example, the cylindrical member 400A can have a substantially circular cross section when viewed from a cut plane perpendicular to the extending direction (in this case, the cylindrical member 400A has an inner diameter of about 7 mm, for example, (can have an outer diameter of 7.1 mm and a length of about 22 mm). In another example, the cylindrical member 400A can have any cross-sectional shape including a substantially elliptical shape, a substantially rectangular shape, and/or a substantially polygonal shape when viewed from a cut plane orthogonal to the extension direction.

Such a cylindrical member 400A may be formed of, for example, a flammable material such as paper (cardboard), plastic, or resin, or a material obtained from any combination of these materials.

Furthermore, when the decorative paper 600A is used, the cylindrical member 400A includes the decorative paper 600A as a component (the cylindrical member 400A cooperates with the decorative paper 600A to form the cylindrical member). It is possible to understand.

In addition, if the cylindrical member 400A only has enough strength to be significantly damaged when being pushed into the second cylindrical member 210B of the pattern product 1, the inside of the second cylindrical member 210B may be damaged. It may be difficult to reach the formed contact surface 219B. Therefore, it is preferable that the cylindrical member 400A has such strength that it will not be significantly damaged when being pushed into the second cylindrical member 210B of the patterned product 1. The strength of the cylindrical member 400A can be increased, for example, by increasing the thickness of the material that constitutes the cylindrical member 400A.

(2-2) Gunpowder 500A
The gunpowder 500A may be formed to extend from one end 502A to the other end 504A and have a rod shape. Explosive powder 500A may be formed using pyrotechnic powder. In one example, the gunpowder 500A can be formed by wrapping pyrotechnic powder around a thin rod (post) made of a combustible material (paper, etc.). Further, the gunpowder 500A can include gunpowder for ignition at the other end 504A. As these explosives, any of the known explosives conventionally used in "sparklers" can be used.

Further, the gunpowder 500A has a substantially circular shape, a substantially elliptical shape, a substantially rectangular shape, and/or a substantially rectangular shape so as to match the cross-sectional shape of the cylindrical member 400A when viewed from a cut surface perpendicular to the extension direction (left-right direction on the page). It can have any cross-sectional shape including a substantially polygonal shape.

Only a portion of the gunpowder 500A on the one end 502A side can be accommodated inside the cylindrical member 400A and fixed using an adhesive or the like.

Note that the gunpowder 500A can have a length of, for example, about 100 mm to about 250 mm.

(1-3) Decorative paper 600A
The decorative paper 600A can cover part or all of the cylindrical member 400A in order to decorate the appearance of the product. The decorative paper 600A may include one or more sheets of paper (thin paper) that is a combustible material. As described above, the decorative paper 600A can be understood to be a part of the cylindrical member 400A (cooperating with the cylindrical member 400A to form the cylindrical member).

Such a gunpowder product 2A is designed so that the user can remove the wall portion 406A formed at one end 402A of the cylindrical member 400A from the second cylindrical member 210B included in a certain cylindrical member 210 of the patterned product 1 described above. By pushing the cylindrical member 400A into the second cylindrical member 210B until it comes into contact with the abutting surface 219B (see FIG. 6), the pattern product 1 is supported by (the second cylindrical member 210B of) the cylindrical member 400A. can be done. Thereby, the explosive product 2A can cooperate with the handle product 1 to form a fireworks product ("sparkler").

In this way, the cylindrical member 400A, particularly the one end 402A of the cylindrical member 400A, has enough strength to substantially maintain its shape without being significantly damaged even if it is pushed into the second cylindrical member 210B. can have Further, once the cylindrical member 400A is pushed into and supported inside the second cylindrical member 210B, especially the one end 402A of the cylindrical member 400A, the user moves the explosive product 2A away from the second cylindrical member 210B. By pulling it out, it can be removed from the second cylindrical member 210B. Therefore, the gunpowder product 2A, that is, the cylindrical member 400A, particularly the one end 402A of the cylindrical member, can be detachably attached to the second cylindrical member 210B of the patterned product 1 (in other words, the second cylindrical member 210B of the patterned product 1 The cylindrical member 210B can be removably attached to one end 402A of the explosive product 2A). This similarly applies when decorative paper 600A is used.

(3) Explosive product 2B according to yet another embodiment
A specific example of the configuration of an explosive product according to yet another embodiment will be described with reference to FIG. 11. FIG. 11 is a cross-sectional view schematically showing an example of the configuration of an explosive product according to yet another embodiment. Note that in FIG. 11, the same reference numerals as those shown in FIG. 9 are given to the same components as those shown in FIG. Hereinafter, only the configurations different from the configuration shown in FIG. 9 will be described, and the description of the same configurations as the configuration shown in FIG. 9 will be omitted.

The explosive product 2B can include a combustion promoting material (a completely combustible material) 800 disposed inside the cylindrical member 400 between the explosive 500 and the wall portion 406.

Since the gunpowder product 2B burns the gunpowder 500 in the direction toward the one end 402 (wall portion 406) of the cylindrical member 400, the gunpowder product 2B has the highest possibility of remaining unburned. This is the portion located on the one end 402 side of the cylindrical member 400. In view of this, in the explosive product 2B, the completely combustible material 800 can be placed in a portion close to one end 402 of the cylindrical member 400, that is, between the explosive 500 and the wall portion 406. As a result, the combustion of the portion of the explosive product 2B on the one end 402 side of the cylindrical member 400 is promoted by the completely combustible material 800, thereby increasing the possibility that the entire explosive product 2B will be combusted.

As the completely combustible material 800, for example, solid nitrified cotton (nitrocellulose) of about 1 g or less can be used without limitation.

Further, in a state where the gunpowder product 2B is supported by the handle product 1, a portion P of the gunpowder product 2B accommodated in the second cylindrical member 210B (included in a certain cylindrical member 210) of the handle product 1 The amount of air supplied to ₁ may be relatively small compared to the amount of air supplied to other parts of the explosive product 2B. Here, P ₁ indicates the distance from the end face/wall portion 406 along the longitudinal direction of the explosive product 2B. In view of this, in one example, a portion of the cylindrical member 400 from the end face/wall portion 406 to a distance corresponding to about 30% to about 60% of the portion _P1 is filled with the completely combustible material 800. It is preferable. In another example, a portion of the cylindrical member 400 from the end face/wall portion 406 to a distance corresponding to about 40% to about 50% of the portion _P1 is further filled with a completely combustible material 800. preferable. This can further increase the possibility that the entire explosive product 2B will burn.

In another example, the handle product 1 of the gunpowder product 2B is preferably burned out more reliably, so that the part of the gunpowder product 2B that is connected to the handle product 1 (i.e., the part P ₁ ) is preferably completely burnt out. A configuration may be adopted in which all of the portion _P1 accommodated in the second cylindrical member 210B is filled with the completely combustible material 800.

(4) Explosive product 2C according to yet another embodiment
A specific example of the configuration of an explosive product according to yet another embodiment will be described with reference to FIG. 12. FIG. 12 is a cross-sectional view schematically showing an example of the configuration of an explosive product according to yet another embodiment. Note that in FIG. 12, components common to those shown in FIG. 10 are given the same reference numerals as those shown in FIG. Hereinafter, only the configurations different from the configuration shown in FIG. 12 will be described, and the description of the same configurations as the configuration shown in FIG. 10 will be omitted.

The explosive product 2C can include a combustion-promoting material (completely combustible material) 800 disposed between the explosive 500A (one end 502A) and the wall 406A inside the cylindrical member 400A.

Since the gunpowder product 2C burns the gunpowder 500A in the direction toward the one end 402A (wall portion 406A) of the cylindrical member 400A, the gunpowder product 2C has the highest possibility of remaining unburned. This is the portion located on the one end 402A side of the cylindrical member 400A. In view of this point, in the explosive product 2C, the completely combustible material 800 can be placed in a portion close to one end 402A of the cylindrical member 400A, that is, between the explosive 500A and the wall portion 406A. As a result, the combustion of the portion of the explosive product 2C on the one end 402A side of the cylindrical member 400A is promoted by the completely combustible material 800, thereby increasing the possibility that the entire explosive product 2C will be combusted.

As the completely combustible material 800, for example, solid nitrified cotton (nitrocellulose) of about 1 g or less can be used without limitation.

Further, in a state where the gunpowder product 2C is supported by the handle product 1, a portion P of the gunpowder product 2C accommodated in the second cylindrical member 210B (included in a certain cylindrical member 210) of the handle product 1 The amount of air supplied to ₂ can be relatively small compared to the amount of air supplied to other parts of the explosive product 2C. Here, _P2 indicates the distance from the end face/wall portion 406A along the longitudinal direction of the explosive product 2C. In view of this, in one example, a portion of the cylindrical member 400A from the end face/wall portion 406A to a distance corresponding to about 30% to about 60% of the portion _P2 is filled with the completely combustible material 800. It is preferable. In another example, a portion of the cylindrical member 400A from the end face/wall portion 406A to a distance corresponding to about 40% to about 50% of the portion _P2 is further filled with the completely combustible material 800. preferable. This can further increase the possibility that the entire explosive product 2C will burn.

In another example, the handle product 1 of the gunpowder product 2C is preferable because it is preferable to more reliably burn out all the parts of the gunpowder product 2C that are connected to the handle product 1 (that is, the part P ₂ ). A configuration may be adopted in which all of the portion _P2 accommodated in the second cylindrical member 210B is filled with the completely combustible material 800.

4. How to use the above-mentioned handle product 1 and explosive product 2, 2A to 2C will be briefly explained. Here, we will focus on a case where the patterned product 1 uses both the optional outer cylindrical member 220 and the cover member 300 (the patterned product 1 uses at least one of the outer cylindrical member 220 and the cover member 300). For cases in which one of the members is not used, the usage method in that case can be understood by reading the following explanation excluding the description of the member in the following explanation.)

A user (user U in this case) can prepare (purchase) a patterned product 1 on the premise that it will be used repeatedly. Further, the user U can prepare (purchase) a desired explosive product from among the plurality of explosive products 2, 2A to 2C available on the market.

Referring to FIGS. 1 and 2, the user U inserts the other end 104 of the rod-shaped member 100 of the patterned product 1 into the attachment portion 302 of the cover member 300, and then grips the attachment portion 302 and attaches the rod-shaped member 100. can be pressed toward one end 102 of. Thereby, the user U can slide the cover member 300 along the perforation direction of the rod-shaped member 100 and arrange the cover member 300 so as to cover the outer cylindrical member 220, as shown in FIG. Can be done.

Referring to FIGS. 9 and 6, the user U realizes that one end 402 of the cylindrical member 400 included in the explosive product (here, the explosive product 2 as an example) is inside the second cylindrical member 210B of the handle product 1. The cylindrical member 400 can be pushed into the second cylindrical member 210B until it abuts the formed abutment surface 219B. Thereby, the explosive product 2 can be accommodated and supported in the second cylindrical member 210B of the handle product 1.

(In addition, if the user U accidentally attaches an unintended explosive product 2 to the patterned product 1, the user U should grasp the cylindrical member 400 of the explosive product 2 and pull or press it in the direction away from the patterned product 1. By doing so, the gunpowder product 2 can be removed from the handle product 1.)

The user U can ignite the other end 404 of the explosive product 2 shown in FIG. As a result, as the ignition gunpowder placed inside the cylindrical member 400 burns near the other end 404 of the gunpowder product 2, among the plurality of types of gunpowder placed inside the cylindrical member 400, The first type of gunpowder placed adjacent to the ignition gunpowder burns to generate sparks, while also burning the cylindrical member 400 surrounding the gunpowder.

By the time the first type of gunpowder finishes burning completely, the second type of gunpowder placed adjacent to the first type of gunpowder burns and generates sparks while expelling this gunpowder. The surrounding cylindrical member can also be burned. In this way, the cylindrical member 400 can burn from the other end 404 toward the one end 402 together with the gunpowder contained therein.

When combustion reaches the portion of the cylindrical member 400 housed inside the second cylindrical member 210B, the notch 210a formed in the second cylindrical member 210B, at least one first air hole 212a (see FIG. 6) and at least one second air hole 236 (see FIG. 5) formed in the connecting member 230 adjacent to the outer cylindrical member 220. The air can be supplied to the cylindrical member 400 housed inside the second cylindrical member 210B. As a result, a larger portion of one end 402 of the cylindrical member 400 can be burned, if not the entirety. Note that when the gunpowder product 2B or the gunpowder product 2C is used, one end 400 of the cylindrical member 400 contains a completely combustible material 800 therein, so that a larger portion can be combusted.

While the cylindrical member 400 and the gunpowder are burning in this way, the heat generated by such combustion is transferred to the second cylindrical member 210B, so that the second cylindrical member 210B becomes high temperature. obtain. The outer cylindrical member 220 can form a layer of air between it and the second cylindrical member 210B which has reached a high temperature. The presence of such an air layer can at least partially suppress conduction of heat from the second cylindrical member 210B to the outer cylindrical member 220. Further, the outer cylindrical member 220 can restrict the user U from touching the second cylindrical member 210B which is in a high temperature state. Further, a cover member 300 is arranged to cover the outer cylindrical member 220. Thereby, the cover member 300 can restrict the user U from touching the second cylindrical member 210B that is in a high temperature state and the outer cylindrical member 220 that covers the second cylindrical member 210B. As a result, user U can enjoy fireworks without getting burned.

After the combustion of the cylindrical member 400 is completed, the user U operates the patterned product directly above a non-flammable trash can or the like so that the opening 218B of the second cylindrical member 210B faces downward. Soot and the like that may remain inside the second cylindrical member 210B can be thrown away into the trash can or the like.

Next, the user U can enjoy fireworks by attaching other explosive products 2, 2A to 2C to the patterned product 1 in the same manner as described above.

Note that the gunpowder products 2, 2A to 2C disclosed in the present application lack a handle portion or a corresponding portion that can be held by a user (remains without burning). Therefore, such a handle part will not be left unattended in a place where fireworks are enjoyed.

After finishing the fireworks, the user U exposes the outer cylindrical member 220 by sliding the cover member 300 to the position shown in FIG. 1 or 2 or by removing it from the bar member 100. be able to. The user U can clean the second cylindrical member 210B, the outer cylindrical member 220, etc. using a brush, a bundler, a cotton swab, a blower, a vacuum cleaner, a high pressure washer, or the like. At least one second air hole 236 (see FIGS. 6 and 7) formed in the connecting member 230 adjacent to the outer cylindrical member 220 is provided inside the outer cylindrical member 220 (in particular, in the outer cylindrical member 220). This can help in cleaning the area (near one end 222 of 220) more efficiently. Furthermore, the notch 210a and at least one first air hole 212a formed in the second cylindrical member 21B can help more efficiently clean the inside of the second cylindrical member 21B. .

The user U can use (recycle) the handle product 1 that has been cleaned in this way by combining it with new explosive products 2, 2A to 2C at any later timing. Of course, the user U can also reuse the patterned product 1 without cleaning it.

As will be readily understood by those skilled in the art who have the benefit of this disclosure, the various examples described above can be used in appropriate combinations with each other in various patterns, as long as no contradiction occurs.

As explained above, the gunpowder products 2, 2A to 2C lack a handle portion or a corresponding portion that remains unburned and is held by the user. Further, the patterned product 1 can be reused by the user. Therefore, according to the technology disclosed in the present application, the amount of generated dust can be at least partially suppressed.
