Utility Model Registration No. 3141615

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  Further, the resin film covered with thin paper may be made of a biodegradable resin.

  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.

  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.

  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.

  Preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In addition, all of the configurations described below are not necessarily essential requirements of the present invention.

  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.

  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.

  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.

  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.

  Next, the use of the smoke cover paper 1 for launching a smoke fire will be described.

  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.

  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. .

  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.

  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.

  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.

  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.

  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.

  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.

  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.
