Description

  The present invention relates to a balloon bursting apparatus, and also relates to a balloon bursting type production apparatus using the balloon bursting apparatus. More specifically, the rubber balloon itself, or a rubber balloon containing a small balloon or a confetti piece inside can be easily and reliably ruptured in an attractive manner, thereby improving the effect of the event. The present invention relates to a balloon bursting apparatus that contributes to making a balloon burst, and also relates to a balloon bursting type production apparatus that uses the balloon bursting apparatus.

  For example, at a wedding reception, a birthday party at home, or various events such as a recital or various competitions, a rubber balloon that contains small balloons or confetti pieces inside is ruptured. Thus, the effect of the event is improved by scattering the small balloons inside or scattering the small pieces in the air like a snowstorm.

  By the way, as a conventional means for rupturing a rubber balloon as described above, for example, as disclosed in Patent Document 1 and Patent Document 2, a needle is inserted into the balloon to rupture it, or heat is generated by energization. The heating element is attached to the side of the balloon with an adhesive tape or the like, and the balloon is melted and ruptured by the heat generated by the heating element. Furthermore, a sheet body containing explosives is attached to the side of the balloon with an adhesive tape or the like, and the balloon is ruptured by the explosion of the explosive.

  However, the means to puncture the balloon by piercing the needle is usually that an operator other than the operator holding the balloon holds the needle with a needle with a long needle protruding from the tip by hand and pierces the balloon. However, there was a problem that required two operators. In addition, when the needle is inserted into the balloon, the balloon may fluctuate and escape, and the balloon may not be surely ruptured by the needle insertion. In addition, when the needle is pierced into a thick part close to the balloon's mouth instead of the thin side of the balloon, it must be pierced again because the balloon cannot be ruptured even though a hole can be made in the balloon. There was a problem that the balloon could not be surely burst. In addition, the way the balloons pierced with the needle was not very nice. Furthermore, at a birthday party at home, such as a party where the child is the leading role, if the management of the needle bar after the balloon bursts is poor, the child will swing the needle bar and injure with the needle. It was dangerous because there was a fear.

  Further, when the heating element or the sheet body containing explosives is attached to the side surface of the balloon, there is a problem that the attached heating element, sheet body, or lead wire impairs the appearance of the balloon. In particular, when the explosive means using explosives was used, the powder of explosives was scattered and was not preferable.

Therefore, the scratch balloon 61 can be stretched to be thinner and scratched by the scratch portion 61. Thereby, the balloon 2 can be more reliably ruptured.

  As described above, since the balloon 2 is in a stable state with respect to a lateral load from any direction and is supported by the cone-shaped cylindrical body 23, when the balloon 2 is scratched in this way, the balloon 2 is Rolling of the balloon, such as escaping away from the scratching member 5, is prevented. Therefore, the scratching action is reliably imparted, and the balloon 2 can be reliably ruptured.

  In this embodiment, the blowing tubular portion 10 is pulled and extended, the lower end portion 79 of the blowing tubular portion 10 is passed through the guide groove 35, and the ring-shaped portion 15 is placed on the lower surface side of the fastening hole 36. Therefore, the portion 95 (FIGS. 4 and 13) above the first support portion 20 of the balloon 2 is pulled to become thin. As a result, the balloon is more easily ruptured more reliably by the scratching action of the scratching member 5.

  When the balloon 2 bursts in this way, the air compressed inside the balloon is released instantly together with the bursting of the balloon, so that the small balloon 16 accommodated inside the balloon 2 is scattered by the wind pressure. Moreover, the small pieces 17 accommodated can be scattered like a snowstorm. As a result, various events such as wedding receptions, Christmas feasts, birthday parties in each family, piano and ballet presentations, and various competitions can be gorgeously produced.

  In the present embodiment, as described above, the contact preventing protrusion 66 having, for example, a rectangular tube shape is provided on the scratched portion 61 side of the elastic bending piece 62. Therefore, in the balloon bursting type production device 7, the upper surface 96 of the contact prevention projection 66 is pushed downward by the scratching balloon peripheral surface portion 60 of the balloon 2 attached to the cone-shaped cylindrical body 23. Therefore, as shown in FIGS. 4 and 13, the scratching portion 61 is in a state of being separated from the scratching balloon peripheral surface portion 60. Therefore, there is no fear that the scratching portion 61 contacts the scratching balloon peripheral surface portion 60, and the balloon 2 comes into contact with the scratching portion 61 due to vibrations when transporting the balloon bursting type effect device 7, and carelessly occurs. There is no fear of bursting.

  In this embodiment, as shown in FIGS. 2 and 4, the scratch member 5 is provided compactly on the disc body 25a, and the scratch member 5 is covered with the attached balloon 2. Since it is hidden and is not visually recognized, as shown in FIG. 1, this balloon bursting type | formula production apparatus 7 can be comprised beautifully. As shown in FIG. 12, the operation of rupturing the balloon 2 involves holding the handle cylinder part 26 with one hand and pulling the pull string 67 downward with the other hand. It is interesting that the operator can smartly burst the balloon 2 in the same manner as a conventional cracker. The event effect can be improved also from this aspect.

  After the balloon 2 is ruptured, in this embodiment, as shown in FIG. 2, the scratching member 5 is an empty space on the upper end side of the cone-shaped cylindrical portion 29 that forms the upper portion of the disc body 25a. Therefore, there is no risk of injury from the scratching portion 61 because the state is stored in the place 97.

  In this embodiment, as described above, the lower end 79 of the blow-in tubular portion 10 is passed through the guide groove 35 and the ring-shaped portion 15 is engaged with the edge 80 on the lower surface side of the fastening hole 36. Since the configuration is adopted in which the balloon 2 is attached to the cone-shaped cylinder 23 by combining the balloons 2, after the balloon 2 is ruptured as described above, a new balloon is inserted in the same manner as described above. 23 can be easily attached. As a result, a new balloon bursting type production device 7 can be constructed by reusing the balloon bursting device 1 in which the balloon support 3, the scratching member 5 and the operation means 6 are incorporated.

  When the balloon rupture device 1 is used repeatedly as described above, the elastic bending piece 62 may be bent, for example, as shown in FIG. Even with such a curl, in the state where the balloon 2 is attached to the cone-shaped cylinder 23, the contact preventing projection 66 is pushed toward the disc body 25a by the scratch balloon peripheral surface portion 60. Therefore, there is no fear that the scratching part 61 contacts the scratching balloon peripheral surface part 60 of the balloon 2, and therefore, inadvertent bursting of the balloon can be prevented.

  The present invention is by no means limited to those shown in the above-described embodiments, and it goes without saying that various design changes can be made within the scope of the claims. One example is as follows.

(1) FIGS. 14 to 15 show other modes of the balloon bursting type effect device 7 configured by attaching the balloon 2 to the cone-shaped cylinder 23. In the figure, a balloon mounting portion 100 provided at a lower center portion 99 of a support member 25 as a disc body 25a to be fitted and fixed in a portion close to the tip 28 inside the cone-shaped cylindrical portion 29. In addition, a linear support shaft 101 projects downward.

  As shown in FIG. 14, the disk body 25a has the same configuration as that described in the first embodiment, and has an insertion hole 39 in the central portion thereof, and has the same configuration as described above on the upper surface side. A scratching member 5 is provided. The balloon mounting portion 100 is provided with a communication hole 102 communicating with the insertion hole 39, and the upper end portion 104 of the support shaft 101 extending downward is fitted into the lower end cylindrical portion 103 of the communication hole 102.
