Description

本考案は、煙火の打ち上げで使用される煙火筒の開口部に被せる煙火用蓋紙及び煙火用蓋紙が被せられた煙火筒に関するものである。   The present invention relates to a smoke cover paper that covers the opening of a smoke fire cylinder that is used for launching a fire, and a smoke fire cylinder that is covered with a smoke fire cover paper.

煙火の一般的な打ち上げ方法として、導火線または電線を利用したものがある。これらは、一方が開口され、他方に底が設けられた煙火筒で、開口側を上にして煙火筒を設置し、発射薬を袋詰めした火薬袋を、煙火玉の親導(おやみち)と呼ばれる煙火玉の中心から延びている導火線の方に貼り付けたものを、火薬袋を下にして煙火玉を煙火筒に入れる。   As a general method for launching a smoke fire, there is a method using a lead wire or an electric wire. These are smoke canisters that are open on one side and have a bottom on the other side. Install a smoke cannon with the open side up, and use a gunpowder bag filled with propellant as a guide to smoke fireballs. ) Attached to the fire lead that extends from the center of the smoke fireball called), put the smoke fireball into the smoke flame with the gunpowder bag down.

火薬袋から導火線または電線を延ばして、煙火筒内から外へと出した後、煙火筒の開口部に紙蓋を被せて、粘着テープ等で紙蓋と煙火筒を貼り合わせて固定する。そして、煙火玉の打ち上げは導火線であれば点火、電線であれば電流を流すことで火薬袋が爆発し、この爆発の圧力によって煙火玉が打ち上げられるのと一緒に紙蓋も空に舞い上がる(例えば特許文献1参照)。   After extending a lead wire or an electric wire from the gunpowder and taking it out from the inside of the smoke gun, cover the paper lid on the opening of the smoke gun, and attach and fix the paper lid and the smoke gun with an adhesive tape or the like. The fireball is fired if the lead is ignited, and if it is an electric wire, the gunpowder bag explodes by passing an electric current and the fireball is launched by the pressure of this explosion. Patent Document 1).

前述の煙火筒の開口部を覆っている紙蓋は、他の煙火筒からの煙火玉の発射や、火のついた導火線から発生する火の粉が、煙火筒に入り、煙火筒内の発射薬に引火して起こる煙火玉の誤発射を防止している。   The paper cover that covers the opening of the above-mentioned smoke cannon fires smoke fireballs from other smoke cannons, or sparks generated from a ignited lead wire enter the smoke cannon and becomes a propellant in the smoke cannon. Prevents accidental fire of smoke fireballs caused by ignition.

煙火の打ち上げ終了後の片付けで、煙火玉と一緒に空中に舞い上がり、地面に落ちた紙蓋や設置した煙火筒の回収作業がある。これらの作業は手作業で行われ、煙火の打ち上げの規模が大きくなるのにあわせて使用される煙火筒及び紙蓋の数は多く、設置範囲は広くなり、よって紙蓋と煙火筒の回収作業で多くの労力を要する。   After cleaning up the fireworks, they will fly into the air together with the fireballs and collect the paper lids that have fallen to the ground and the fireworks installed. These operations are performed manually, and as the scale of smoke fires increases, the number of smoke canisters and paper covers used is large and the installation range is widened. It takes a lot of effort.

つまり、紙蓋の回収作業では設置範囲が広くなれば、紙蓋が煙火玉の発射にあわせて舞い上がって飛翔する範囲も広くなり、紙蓋の回収範囲も広くなる。煙火筒の回収作業では煙火筒に貼りついて残っているテープを剥がす作業もあり、設置する煙火筒の数の分だけ労力を要する。   In other words, if the installation range is widened in the paper lid collection operation, the range in which the paper lid soars and flies with the fire of the smoke fireballs widens, and the paper lid collection range also widens. In the collection operation of the smoke cannon, there is also an operation of peeling off the tape stuck to the smoke cannon, and labor is required for the number of smoke canisters to be installed.

また、製造面において紙蓋の熱成型を行うのに際して型の作成や、製造するための機具の設置スペースを設ける必要があるなど、コストを要する。   In addition, when performing the thermoforming of the paper lid on the manufacturing side, it is necessary to create a mold and to provide an installation space for the equipment for manufacturing.

本考案は、上記の点に鑑みて提案されたものであって、その目的は、簡易な構造で安価に製造が可能で、煙火打ち上げ終了後の片付けの労力を軽減する煙火用蓋紙及び煙火筒を提供することである。   The present invention has been proposed in view of the above points, and its object is to provide a cover for smoke fire and a smoke fire which can be manufactured at a low cost with a simple structure and reduce the work of cleaning up after the fire is fired. Is to provide a tube.

本考案の煙火用蓋紙は、円形の厚紙と、片面に樹脂フィルムが被覆され、前記厚紙の表面積よりも表面積が大きく、前記厚紙よりも厚みが少なく折り曲げ可能な薄紙と、を備え、該薄紙の樹脂フィルムが被覆されていない面の中央に前記厚紙を接着剤で貼り付けたことを特徴とする。また、本考案の煙火筒は、筒内に火薬袋と煙火玉と導火線とが収容され、前記導火線が外部に引き出された状態、又は筒内に火薬袋と煙火玉と着火部とが収容され、前記着火部の導線が外部に引き出された状態で、請求項1の煙火用蓋紙の前記厚紙が開口部に被せられて、前記薄紙の前記厚紙からはみ出している部分が固縛具で筒上部外周に固縛された、煙火の打ち上げで使用されるものである。   A cover paper for fireworks of the present invention comprises a circular cardboard, and a thin paper that is coated with a resin film on one side, has a surface area larger than the surface area of the cardboard, and has a smaller thickness than the cardboard and can be folded. The cardboard is affixed to the center of the surface not covered with the resin film with an adhesive. Also, the smoke cannon of the present invention accommodates a gunpowder bag, a smoke fireball, and a lead wire in the cylinder, and a state where the lead wire is drawn out, or a gunpowder bag, a smoke fireball, and an ignition part in the tube. In a state where the lead wire of the ignition part is drawn to the outside, the cardboard of the cover for smoke fire according to claim 1 is covered with an opening, and a portion of the thin paper protruding from the cardboard is a cylinder It is used for the launch of fireworks, which are secured to the outer periphery of the upper part.

たとえば、円形の厚紙と、片面に樹脂フィルムが被覆された四角形で1辺の長さが前記厚紙の直径よりも大きい薄紙とを備え、前記薄紙の樹脂フィルムが被覆されていない面の中央に前記厚紙を接着剤で貼り付けた煙火用蓋紙である。煙火筒内に煙火玉と火薬袋を設置し、導火線を火薬袋から煙火筒の外へ延ばした後、煙火用蓋紙の厚紙のある面を下にして煙火筒の開口部に載せて、開口部の外径からはみ出ている部分を煙火筒の外周上部へと畳み、煙火用蓋紙を畳んだ部分と煙火筒の外周上部を固縛具、たとえば、紐で縛るか、または輪ゴムを嵌めることで煙火用蓋紙を煙火筒に固定する。   For example, a circular cardboard and a square with a resin film coated on one side and a thin paper whose length of one side is larger than the diameter of the cardboard, the center of the surface of the thin paper that is not coated with the resin film It is a cover for smoke fire with cardboard attached with an adhesive. Install a smoke fireball and a gunpowder bag inside the smoke gun, extend the lead wire from the gunpowder bag to the outside of the smoke gun, and place it on the opening of the smoke gun with the cardboard side of the smoke cover paper facing down Fold the part that protrudes from the outer diameter of the part to the upper part of the outer periphery of the smoke cannon, and tie the part that folds the cover for the fire and the upper part of the outer part of the smoke canister with a tie, for example, a string or fit a rubber band Attach the cover for smoke fire to the smoke fire tube.

なお、煙火用蓋紙を形成する円形の厚紙の直径は煙火筒の開口部の外径と同じであることが好ましく、四角形の薄紙については各辺の長さが厚紙の直径に対して例えば1.5〜2.5倍である正方形薄紙であることが好ましい。また、厚紙と角形の薄紙の貼り付けに使用される接着剤は市販のものを使用すればよい。   In addition, it is preferable that the diameter of the circular cardboard forming the cover for smoke fire is the same as the outer diameter of the opening of the smoke cylinder, and the length of each side of the square thin paper is, for example, 1 with respect to the diameter of the cardboard. It is preferably a square thin paper of 5 to 2.5 times. A commercially available adhesive may be used for attaching the thick paper and the square thin paper.

煙火玉と火薬袋の煙火筒内への設置については、従来の導火線を用いた打ち上げ煙火の発射と同様に行えばよい。なお、煙火筒内に収容されている着火部とは導線から流れてきた電気を介して発火するものである。   The installation of the smoke fireball and the gunpowder bag in the smoke squib can be performed in the same manner as in the case of launching a smoke fire using a conventional lead wire. In addition, the ignition part accommodated in the smoke-fired cylinder is ignited through the electricity flowing from the conducting wire.

また、薄紙に被覆されている樹脂フィルムは生分解性の樹脂からなるものを使用してもよい。   Further, the resin film covered with thin paper may be made of a biodegradable resin.

以上のような煙火用蓋紙及び煙火筒によれば、煙火筒への固定はテープではなく、固縛具である紐または輪ゴムを使用することから、煙火の打ち上げ終了後の煙火筒回収時に煙火筒に貼り付いている残りのテープを剥がす作業が省かれる。また、煙火の打ち上げにおいて煙火玉と共に煙火用蓋紙も空に舞い上がるが、煙火筒に固定する際に畳んだ部分が広がることで、上昇時に煙火用蓋紙が受ける空気抵抗は大きくなることから遠くまで飛びにくくなり、地面に落ちた煙火用蓋紙の回収範囲は狭めることができる。以上のことから後片付けに要する労力の軽減を図ることができる。   According to the above-mentioned cover for smoke fire and the smoke cannon, since the strap is not a tape but a string or rubber band which is a lashing tool is used for fixing to the smoke cannon, when the smoke cannon is collected after the fire is launched, The work of removing the remaining tape attached to the tube is omitted. In addition, when the smoke fire is launched, the smoke cover paper also rises in the sky together with the smoke fireball, but because the folded part spreads when fixing to the smoke fire cylinder, the air resistance received by the smoke fire cover increases as it rises. It is difficult to fly to the ground, and the collection range of the cover for smoke fire that has fallen on the ground can be narrowed. From the above, the labor required for post-cleaning can be reduced.

また、円形の厚紙と薄紙とを接着剤で貼り付けるのみであるので、製造がシンプルになり、煙火用蓋紙を低廉な価格で提供することができる。   Further, since the circular thick paper and the thin paper are simply pasted with an adhesive, the manufacture is simplified, and the smoke cover paper can be provided at a low price.

なお、当業者に自明な範囲で上記の本考案の構成要件を適宜調整しても構わない。   It should be noted that the above-described constituent elements of the present invention may be appropriately adjusted within a range obvious to those skilled in the art.

本考案における好適な実施の形態について、添付図面を参照して説明する。なお、以下に説明する実施の形態は、実用新案登録請求の範囲に記載された本考案の内容を限定するものではない。また、以下に説明される構成のすべてが、本考案の必須要件であるとは限らない。   Preferred embodiments of the present invention will be described with reference to the accompanying drawings. Note that the embodiments described below do not limit the contents of the present invention described in the claims of utility model registration. In addition, all of the configurations described below are not necessarily essential requirements of the present invention.

図1は本考案の煙火用蓋紙1の斜視図であり、表面は樹脂フィルムが被覆された四角形の薄紙2で樹脂フィルムが被覆されていない裏面の中央に円形の厚紙3を接着剤で貼り付けたものである。   FIG. 1 is a perspective view of a cover 1 for a fireworks according to the present invention. The surface is a rectangular thin paper 2 coated with a resin film, and a circular cardboard 3 is attached to the center of the back surface not coated with a resin film with an adhesive. It is attached.

なお、厚紙3は市販されている厚さ0.5mm〜2mmの厚紙を後述する煙火の打ち上げに使用する煙火筒4の開口部4aの外径と同じ径になるように円形に裁断したものであり、薄紙2はクラフト紙にポリエチレンラミネート加工が施されている厚さ0.02〜1mmの市販の加工紙を各辺が厚紙3の径に対して2倍程度の長さになるように正方形に裁断したものであることが好ましい。接着剤については、市販の酢酸ビニル樹脂系エマルジョン形の接着剤を使用すればよい。   The cardboard 3 is obtained by cutting a commercially available cardboard having a thickness of 0.5 mm to 2 mm into a circular shape so as to have the same diameter as the outer diameter of the opening 4 a of the smoke cylinder 4 used for launching the smoke fire described later. Yes, thin paper 2 is a kraft paper that is made of polyethylene laminate and has a thickness of 0.02 to 1 mm. The processed paper is square so that each side is twice as long as the diameter of the thick paper 3. It is preferable that the material is cut into pieces. As for the adhesive, a commercially available vinyl acetate resin emulsion adhesive may be used.

よって、煙火用蓋紙1は市販の厚紙と薄紙である加工紙をそれぞれ上記の寸法になるように裁断してできた厚紙3と薄紙2を酢酸ビニル樹脂系エマルジョン形の接着剤で接着することで製造される。また、薄紙2の表面に被覆されている樹脂フィルムは、ポリ乳酸等の生分解性の樹脂から構成したものであってもよい。   Therefore, the cover paper 1 for fireworks is obtained by adhering the thick paper 3 and the thin paper 2 obtained by cutting the commercially available thick paper and the processed paper, which are thin paper, to the above-mentioned dimensions with a vinyl acetate resin emulsion adhesive. Manufactured by. The resin film coated on the surface of the thin paper 2 may be composed of a biodegradable resin such as polylactic acid.

また、煙火の打ち上げで使用される煙火筒4は、筒内に火薬袋5と煙火玉6と導火線7が収容され、導火線7が外部に引き出された状態で、煙火用蓋紙1の厚紙3が開口部4aに被せられて、薄紙2の厚紙3からはみ出している部分が固縛具8で筒上部外周に固縛されたものである。   In addition, the smoke cylinder 4 used for the launch of the smoke fire contains the gunpowder bag 5, the smoke fireball 6, and the lead wire 7 in the cylinder, and the cardboard 3 of the smoke cover 1 in a state where the lead wire 7 is drawn to the outside. Is covered with the opening 4 a, and the portion of the thin paper 2 that protrudes from the thick paper 3 is secured to the outer periphery of the upper portion of the cylinder by the securing tool 8.

次に、煙火用蓋紙1の煙火の打ち上げでの使用について説明する。   Next, the use of the smoke cover paper 1 for launching a smoke fire will be described.

図2、3に示すように、煙火筒4で開口部4aを上に向けて設置し、煙火筒4内に火薬袋5と煙火玉6を入れて、火薬袋5から導火線7を上方へ延ばしていき、開口部4aから外へ導火線7を出した後、煙火用蓋紙1を厚紙3が下になるようにし、煙火筒4の開口部4aに厚紙3が載るように煙火筒4の開口部4aに煙火用蓋紙1を置く。火薬袋5と煙火玉6を煙火筒4に入れることについては、通常の導火線を用いた煙火の打ち上げで採られる方法で行えばよい。   As shown in FIGS. 2 and 3, the smoke gun 4 is installed with the opening 4 a facing upward, and the gunpowder bag 5 and the smoke fireball 6 are put in the smoke gun tube 4, and the lead wire 7 is extended upward from the gunpowder bag 5. After opening the lead wire 7 from the opening 4a to the outside, the cover 1 for the smoke fire is placed so that the cardboard 3 is at the bottom, and the opening of the smoke gun 4 is placed so that the cardboard 3 is placed on the opening 4a of the smoke gun 4 Place the cover 1 for fireworks on the part 4a. About putting the gunpowder bag 5 and the smoke fireball 6 into the smoke bomb 4, it may be carried out by a method taken by launching a smoke fire using a normal squib.

なお、本実施例の煙火玉6は4号玉(径が約11.5cmの煙火玉)とし、煙火筒4は煙火玉6の径の大きさに合わせた市販の鉄製の煙火筒を使用し、煙火用蓋紙1の厚紙3の径は煙火筒4の開口部4aに載るように開口部4aの外径に合わせて15.5cm、薄紙2は各辺が30cmであるものが例示される。   In addition, the smoke fireball 6 of this embodiment is No. 4 (smoke fireball having a diameter of about 11.5 cm), and the smoke firearm 4 is a commercially available iron smoke firearm adapted to the size of the smoke fireball 6 diameter. The diameter of the thick paper 3 of the cover 1 for smoke fire is 15.5 cm in accordance with the outer diameter of the opening 4 a so as to be placed on the opening 4 a of the smoke fire cylinder 4, and the thin paper 2 is 30 cm on each side. .

煙火筒4の開口部4aに煙火用蓋紙1を置いた後、煙火用蓋紙1の厚紙3と貼り合わさっていない薄紙2の部分を煙火筒4の方へ畳み、畳むことで煙火筒4の開口部4aの外周を覆う薄紙2の上から輪ゴム8を嵌めて、煙火用蓋紙1を煙火筒4に固定し、煙火の打ち上げの時を待つ。また、煙火玉6の打ち上げにおいても、煙火用蓋紙1を煙火筒4に固定したままの状態で行う。そして、導火線7を点火して煙火玉6を打ち上げると共に、煙火用蓋紙1は煙火筒4から離れて上昇した後、地面へ落下する。なお、煙火用蓋紙1の煙火筒4への固定について輪ゴム8でなく、ビニールや紙製の紐で縛って固定してもよい。   After placing the fire cover 1 in the opening 4a of the smoke cannon 4, the portion of the thin paper 2 that is not bonded to the thick paper 3 of the fire cover 1 is folded toward the smoke can 4 and folded to make the smoke can 4 The rubber band 8 is fitted over the thin paper 2 covering the outer periphery of the opening 4a, the cover paper 1 for the fireworks is fixed to the fireworks cylinder 4, and the time of the fire is started. Also, the smoke fireball 6 is launched in a state where the smoke cover paper 1 is fixed to the smoke cylinder 4. Then, the lead wire 7 is ignited and the smoke ball 6 is launched, and the smoke cover paper 1 rises away from the smoke cylinder 4 and then falls to the ground. In addition, about the fixation to the smoke fire cylinder 4 of the cover paper 1 for fireworks, you may tie and fix with the string made from vinyl or paper instead of the rubber band 8.

また、煙火用蓋紙1の使用について、スターマインなどの煙火の連続打ち上げで狭い範囲に複数の煙火筒が配置された場合を除いて使用することが好ましい。   Moreover, it is preferable to use the cover paper 1 for smoke fire except when a plurality of smoke fire tubes are arranged in a narrow range by continuous launching of fireworks such as star mine.

本実施例により、打ち上げまでの間に他の煙火筒からの打ち上げに伴って発生する火の粉が飛来し、煙火筒4内に侵入して火薬袋5に引火して起こる煙火玉6の誤発射の防止を図ることができる。   According to the present embodiment, the sparks generated by launching from other smoke cannons fly up to the launch, and the smoke fireball 6 is accidentally fired by entering the smoke cannon 4 and igniting the gunpowder bag 5. Prevention can be achieved.

煙火用蓋紙1が煙火筒4に固定されているとき、煙火用蓋紙1は薄紙2の樹脂フィルムの面が表に出ており、降雨によって水が煙火用蓋紙1にかかっても、樹脂フィルムが撥水の役割を果たして煙火筒4内への水の浸入を防ぐ。また、煙火用蓋紙1が火の粉を被る量によっては表に出ている樹脂フィルムが溶けたり、また異物によって傷が付いたりすることで樹脂フィルムの面の一部が欠損し、撥水の効果が十分に発揮できなくなっても、少量の水を被る程度であれば、欠損した部分から水が浸入しても薄紙2の下にある厚紙3が吸収して煙火筒4内への水の浸入を防ぐ。   When the smoke cover 1 is fixed to the smoke cylinder 4, the surface of the resin film of the thin paper 2 is exposed on the surface, and even if water falls on the smoke cover 1 due to rain, The resin film plays the role of water repellency to prevent water from entering the smoke cannon 4. In addition, depending on the amount of the cover paper for fireworks 1 covered with sparks, the resin film on the surface may be melted or scratched by foreign matter, so that part of the surface of the resin film may be lost and water repellent effect Even if the ink cannot be fully exerted, if it is covered with a small amount of water, even if water enters from the missing part, the thick paper 3 under the thin paper 2 absorbs and the water enters the smoke cannon 4 prevent.

煙火筒4に煙火用蓋紙1を固定したままで煙火の打ち上げができるため、打ち上げる直前に煙火用蓋紙1を取り外す時間と労力を要さず、作業者の負担を軽減できる。   Since the smoke fire can be launched while the smoke cover 4 is fixed to the smoke cylinder 4, it is not necessary to take time and labor to remove the smoke cover 1 immediately before launching, and the burden on the operator can be reduced.

煙火筒4へ煙火用蓋紙1を固定するのにテープを使わないため、煙火筒4に残っているテープを剥がす作業が省かれ、また煙火玉6と一緒に煙火用蓋紙1は煙火筒4から離れて上昇するとき、煙火筒4に固定した際に畳んだ薄紙2が広がることで煙火用蓋紙1が受ける空気抵抗は大きくなって飛ぶ距離が短くなることから、地面に落下した煙火用蓋紙1を回収する範囲を広げずに済むので、全ての煙火打ち上げ終了後の片付けに要する労力の軽減を図ることができる。   Since no tape is used to fix the smoke cover 1 to the smoke cylinder 4, the work of removing the tape remaining in the smoke cylinder 4 is omitted, and the smoke cover 1 together with the smoke ball 6 is a smoke cylinder. When rising away from 4, the thin paper 2 folded when fixed to the smoke cannon 4 spreads and the air resistance received by the cover 1 for the fire is increased and the flying distance is shortened. Since it is not necessary to expand the range in which the cover paper 1 is collected, it is possible to reduce the labor required for cleaning up after all the smoke fires have been launched.

煙火用蓋紙1の形状は平らで簡易なものであることから低廉な価格で提供することができ、収納においては嵩張らず、省スペース化を図ることができる。また、片付けで煙火用蓋紙1の回収ができずに放置することになっても、材料のほとんどを占める薄紙は自然分解し、合成樹脂と接着剤の使用は少量であることから、環境への負担は少ない。   Since the shape of the cover 1 for fireworks is flat and simple, it can be provided at a low price, and is not bulky in storage and can save space. Moreover, even if the cover for fireworks 1 cannot be recovered after being put away, the thin paper that occupies most of the material will be naturally decomposed, and the use of synthetic resin and adhesive will be small. There is little burden.

本実施例では実施例1の導火線の点火による煙火の打ち上げに対して、電気点火で使用する煙火用蓋紙1について説明する。図4に示すように実施例1で使用する導火線7を導線9に置き換えて、導線9の火薬袋5への先に点火玉10を設けたものであり、煙火筒4内への火薬袋5と煙火玉6の設置及び火薬袋5に点火玉10を設けて、そこから導線9を延ばして煙火筒4の外へと出した後、煙火用蓋紙1を煙火筒4の開口部4aに被せて輪ゴムを用いて固定する。詳細な説明については、上記の実施例1の説明を援用する。   In the present embodiment, the smoke cover paper 1 used for electric ignition will be described with respect to the launch of smoke by ignition of the lead wire of the first embodiment. As shown in FIG. 4, the lead wire 7 used in the first embodiment is replaced with the lead wire 9, and an ignition ball 10 is provided at the tip of the lead wire 9 to the gunpowder bag 5. After installing the ignition ball 10 on the gunpowder bag 5 and extending the lead wire 9 to the outside of the smoke flame tube 4, the cover 1 for the fire flame is put into the opening 4 a of the smoke flame tube 4. Cover and fix with rubber band. For the detailed description, the description of the first embodiment is used.

また、実施例1と同様に、煙火用蓋紙1を煙火筒4に固定したままの状態で、煙火玉6の打ち上げを行う。本実施例の煙火玉6の打ち上げと、火薬袋5に点火玉14を設けることについては、通常の電気点火と同様の方法を適用すればよい。   Similarly to the first embodiment, the smoke fireball 6 is launched while the smoke cover paper 1 is fixed to the smoke cylinder 4. About the launch of the smoke fireball 6 of the present embodiment and the provision of the ignition ball 14 in the gunpowder bag 5, a method similar to that of normal electric ignition may be applied.

本実施例により、上記実施例1と同様の効果が得られる。   According to the present embodiment, the same effect as in the first embodiment can be obtained.
