  The present invention includes a tape (hereinafter referred to as a paper tape) made of a small light material that is partly folded and wound into a cylindrical shape. The bag body is inflated with exhaled air, gripped by the bag, The present invention relates to an air cracker in which a paper tape that is folded inside the body is blown so that the paper tape can be unwound.

  Crackers are used to enhance the occasion at parties, weddings and birthday celebrations. There is a problem that the paper that wraps the explosive powder of crackers in food and drink has the difficulty of pouring down, and the cleaning up after using the crackers remains. It is a well-known fact that paper tapes are easier to put together and clean up after use.

  Conventional crackers use a small amount of gunpowder to pop out the paper tape. If you wrap the gunpowder in paper and pull the string attached to the cracker, it will explode and the paper tape will be blown off, and the paper tape will be released. During the explosion, the paper wrapping the gunpowder is shattered and scattered with the tape. In addition, since explosives are used, there are inconveniences that limit transportation, mass storage, and sales.

  Therefore, the present invention does not use explosives, and by flying the paper tape with the pressure of air, it is possible to eliminate the factor that the paper is shattered and to obtain the convenience of no restrictions on transportation, mass storage, and sales.

  In the present invention, a flexible synthetic resin-made welded film is joined to two sheets, both ends are welded in the longitudinal direction, an open tube is created in the short direction, and the flexible plastic is cut out separately. Place the tube inside the welded film overlap and put it out partly, weld the periphery of the end face of the welded film that has been die cut, make a bag body that is welded together leaving the tube passage, A part of the paper is folded inside, and a plurality of paper tapes are inserted therein, and the mouth part is adhered and sealed with paper or the like which is easily torn. Insert a thin tube, such as a straw, into the unwelded tube passage, inflate the bag body against the mouth, pull out the straw, grip the body of the inflated bag body, and apply pressure to the inside An air cracker where the folded back part breaks the paper pasted at the entrance, and when it is torn, a sound is generated and at the same time the paper tape inside is pushed out and the paper tape is unraveled and scattered.

In addition, the present invention is a blow in which a tube as described above is welded to a weldable synthetic resin blowing port, and a tube is welded to the inside of two flexible synthetic resin welded film shapes that have been punched separately. Place the mouth, weld the periphery of the end face of the welded film that has been die cut, create the bag body, form the structure described above, inflate the bag body from the blower mouth, grasp the trunk, and apply pressure to the inside An air cracker that breaks the paper affixed to the entrance, makes a sound when it breaks, pushes out the paper tape inside, and scatters as the tape unwinds.

  A check valve is attached to the air outlet, and a die-cut welded film is formed by placing a die with a non-return valve attached inside the two laminated synthetic resin welded plastic films Welded around the end face of the paper, made a bag body, formed the structure described above, inflated the bag body from the blower mouth, grabbed the trunk, and applied the paper with the part folded back inside by applying pressure An air cracker that generates sound when it is torn and torn, and at the same time pushes out the paper tape inside, and then scatters as the tape is unwound.

  The air cracker of the present invention is made of a flexible synthetic resin film material, so that the bag formed by welding is blown with a straw, blower, and check valve at the portion corresponding to the air insertion port. Breath can be easily blown from the mouth and inflated easily, and pressure applied by hand can be easily applied, pressure to break the sealed paper works, and the paper tape provided in the bag can be blown off. Paper tape is blown out by air pressure without using gunpowder, so it can be used in places where paper is not eaten and eaten, and can be used easily by children, and there are restrictions on storage and sales. There is an effect that can be not convenient.

  As for the best mode for carrying out the present invention, FIG. 1 is a perspective view of a state of use inflated by exhalation. Referring to FIG. 1, a description will be given of a welded film made of a synthetic resin having flexibility. A tube is placed on the inner side of a flexible synthetic resin welded film made of flexible plastic that is welded in the longitudinal direction at the opposite ends of the sheet and cut open in the short direction. , Welded around the end face of the welded film shape that was punched out, made a bag body that was integrally welded leaving the tube passage, folded part of the bag body inside, and inserted several small paper tapes into it Adhere and seal the mouth part with easily tearable paper. A thin tube, such as a straw, can be inserted into a non-welded tube passage, and the bag can be inflated in the mouth.

  FIG. 2 is a perspective view of an example of a tube used in the air cracker according to claim 1. A flexible synthetic resin-made welded film-like sheet 1 is vertically stacked, and both ends are welded 2 in the longitudinal direction to create a tube 3 that is open in the short direction.

  FIG. 3 is an example of a plan view of the welded air cracker. Separately punched flexible synthetic resin welded film-like sheet 4 is placed on the inner side, and a part of the tube 3 is placed outside and welded around the end face of the stamped welded film-like sheet 4 5 and making the bag body 6 integrally welded, leaving the passage of the tube 3, and partially folding back the inner portion 7 of the bag body 6.

  FIG. 4 is a cross-sectional view of an example of an air cracker. A plurality of paper tapes 8 are inserted into the folded portion 7, and the mouth portion is adhered and sealed with paper 9 or the like which is easily broken. When a thin tube, such as a straw 10, is inserted into the passage of the tube 3 that is not welded, the bag body 6 is inflated against the mouth, and the straw 10 is pulled out, the film-like sheet 1 of the tube 3 is intimately inflated. Air is prevented from leaking from the tube 3, gripping the body 11 of the inflated bag 6 shown in FIG. 1, and by applying pressure, the folded portion 7 is pushed inward to break the easily torn paper 9 attached to the entrance. When a tear occurs, a bursting sound is generated. At the same time, the paper tape 8 inside is pushed out, and the paper tape 8 scatters while being unwound.

FIG. 5 is a perspective view of an example of an air outlet according to claim 2. A film-like sheet 13 is welded 15 to the blowing port 12 made of a synthetic resin that can be welded, and the film-like sheet 13 is a tube so that air from the blowing port 12 can pass through.
FIG. 6 shows an enlarged partial cross-sectional view of the air outlet that swells over the mouth. A blown film 12 having a film-like sheet 13 welded to the blower opening 12 is disposed inside the laminated synthetic resin welded film-like sheet 16 that has been die-cut, and the welded film-like sheet is die-cut. 3 is welded 5 as shown in FIG. 3, gripping the body 11 of the bag body 6 inflated to the state shown in FIG. No. 9 is ruptured, and a bursting sound is produced when it is torn, and at the same time, the paper tape 8 inside is pushed out, and the paper tape 8 is scattered while being unwound.

  FIG. 7 shows a cross-sectional view of an example of a blow-off port with a check valve that swells in the mouth according to claim 3. In order to prevent air from returning to the weldable synthetic resin blowing port 17, a thin film 18 having one end fixed is provided and serves as a valve. When air is blown, the film 18 falls and opens. If the air is blown and expanded, the film 18 is welded to the air outlet 19 with the check valve that closes the membrane 18 in close contact with the wall of the air outlet 17, and the air is provided with the check valve. The air is blown from the blowing port 19 and pushes the film 18 and flows through the film-like sheet 13.

  FIG. 8 shows an enlarged partial cross-sectional view of the air outlet that swells over the mouth. Separately, a blown film 19 with a check valve in which a film-like sheet 20 is welded is placed on the inner side of a laminate of a flexible synthetic-resin-made welded film-like sheet 21, and the die-cut welded film-like sheet 3 is welded 5 as shown in FIG. 3, and the body 11 of the bag body 6 inflated to the state shown in FIG. 7 is pushed up and the tearable paper 9 stuck at the entrance is torn, and when it is torn, a bursting sound is generated, and at the same time, the paper tape 8 inside is pushed out and the paper tape 8 is unwound and scatters.

  Crackers with gunpowder are used to celebrate the party, wedding and birthday celebrations. When using a cracker, there is a difficulty that the paper wrapped in the cracker's gunpowder is shattered and poured down on the floor and food and drink, and the cleaning up after using the cracker remains. Even in the manufacturing process, transportation, and sales, even though it is a small amount, the use of explosives requires careful attention, and the present invention breaks the paper that has been sealed with the pressure of the hand that has been inflated by exhalation. When it tears, a popping sound is generated and the paper tape can be skipped and unwound. An air cracker that does not use gunpowder can be created because a sound similar to that of a cracker containing gunpowder is generated when the paper is torn. In addition, it is a well-known fact that paper tapes are easier to put together and clear after use.
