When the member 200 is externally fitted to the first nozzle member 100, the tip of the outer peripheral wall 210 of the second nozzle member 200 covers the recess 110, and the first nozzle member 100 and the second nozzle member 200 are covered. Are provided with a volume changing mechanism 300 that can change the volume of the space S surrounded by the first nozzle member 100 and the second nozzle member 200.

  As shown in FIG. 4, the rubber balloon body 500 to which the flying balloon balloon nozzle 1000 according to the embodiment of the present invention is attached is formed in a rod shape with the tip side slightly inflated. The rear end of the rubber balloon main body 500 is opened as a mouth 510, and a flying rubber balloon nozzle 1000 is attached to the mouth 510. At the mouth 510 of the rubber balloon main body 500 to which the nozzle 520 is attached, a convex ridge 511 that is thicker than other portions is formed.

  The first nozzle member 100 is formed of a synthetic resin in a substantially cylindrical shape. As shown in FIGS. 1 and 2, a concave portion 110 is formed on the distal end side of the outer peripheral portion 120. The concave portion 110 is a portion into which the convex vein portion 511 of the rubber balloon main body 500 is fitted. Further, a first side sawtooth portion 130 is formed in the middle part of the outer peripheral surface 120 of the first nozzle member 100. The first side sawtooth portion 130 constitutes the volume changing mechanism 300 together with a second side sawtooth portion 231 described later.

  The rear end side of the first nozzle member 100, that is, the side on which the second nozzle body 200 is attached is open. Further, an opening 140 is formed on the tip side of the first nozzle member 100.

  The second nozzle member 200 is made of a synthetic resin and has a substantially bottomed cylindrical shape. As shown in FIGS. 1 and 3, the bottom 220 has an opening 221 serving as an injection hole. A second serrated portion 231 is formed on the inner periphery 211 side of the outer peripheral wall 210 of the second nozzle member 200. The second serrated portion 231 constitutes the volume changing mechanism 300 together with the first serrated portion 130 described above.

Further, on the outer peripheral 212 side of the outer peripheral wall 210 of the second nozzle member 200, a single ridge portion 213 protrudes.
The ridge portion 213 is a portion that closes the opening 221 with the thumb and hooks the index finger and the middle finger when holding the rubber balloon body 500 into which air has been blown. Further, when air is blown into the rubber balloon main body 500 using a dedicated blowing member 600 described later, this is a portion that becomes a catch when the rubber balloon main body 500 is pushed from the blowing member 600.

The second nozzle member 200 is set so as to be fitted inside the first nozzle member 100. In addition, the second nozzle member 200 is fitted inside the first nozzle member 100 in a state where the second serrated portion 231 is engaged with the first serrated portion 130. When the second nozzle member 200 is fitted into the first nozzle member 100, the first nozzle member 100 and the second nozzle are selected by appropriately selecting positions where the first sawtooth portion 130 and the second sawtooth portion 231 are fitted. The volume of the space S surrounded by the member 200 can be changed.
The outer peripheral portion 120 of the first nozzle member 100 and the outer peripheral wall 210 of the second nozzle member 200 are thick enough to be deformed to some extent so that the combination of the first nozzle member 100 and the second nozzle member 200 goes smoothly. The dimension is set.

The volume of the space S surrounded by the first nozzle member 100 and the second nozzle member 200 is related to the level of sound generated when the rubber balloon body 500 flies. The larger the space S, the lower the sound emitted when flying, and the smaller the space S, the higher the sound emitted when flying.
Therefore, by changing the volume of the space S surrounded by the first nozzle member 100 and the second nozzle member 200 by the volume changing mechanism 300, it is possible to change the sound emitted when flying.

  The convex vein portion 511 of the mouth portion 510 of the rubber balloon main body 500 fitted in the concave portion 110 of the first nozzle member 100 is the tip of the outer peripheral wall 210 of the second nozzle member 200 fitted on the first nozzle member 100. As a result of covering the recess 110, it is pushed into the portion surrounded by the recess 110 and the tip of the outer peripheral wall 210. For this reason, the flying rubber balloon nozzle 1000 is attached to the mouth 510 of the rubber balloon body 500 in a state where it does not come off.

The flying rubber balloon nozzle 1000 configured as described above is a state in which only the first nozzle member 100 is attached to the rubber balloon body 500, or the first nozzle body 100 is attached to the rubber balloon body 500. The second nozzle main body 200 may be sold in a state where the second nozzle main body 200 is lightly fitted into the main body 100, or the rubber balloon main body 500, the first nozzle member 100, and the second nozzle part 200 are separated.
Regardless of the state in which the product is sold, the user adjusts the space S composed of the first nozzle member 100 and the second nozzle member 200 to change appropriately so that the user can fly at a sound of his / her favorite height. can do.

The blowing of air into the rubber balloon main body 500 to which the flying rubber balloon nozzle 1000 is attached is performed from the opening 221 serving as the injection hole of the second nozzle member 200.
The air may be blown by the user by directly attaching a mouth to the nozzle 1000 of the flying rubber balloon, or a dedicated air pump or the following blowing member 600 may be used.

As shown in FIG. 5, the dedicated blowing member 600 includes a mouthpiece portion 610 having a small diameter and a substantially cylindrical shape, a connecting portion 620 having a substantially cylindrical shape larger in diameter than the mouthpiece portion 610, and the connecting portion 620. And an intermediate part 630 that connects the mouthpiece part 610 to each other. The connecting part 620 is inserted with a second nozzle member 200 constituting a flying rubber balloon nozzle 1000 attached to the rubber balloon body 500.
Further, a filter 640 is set inside the connecting portion 620. The filter 640 prevents at least saliva from passing, and is formed in a substantially cylindrical shape. The filter 640 is stopped by the step portion 621 inside the connecting portion 620.
Further, a spherical check valve 650 exists inside the intermediate portion 630 between the filter 640 and the mouthpiece portion 610. The check valve 650 has a diameter larger than the inner diameter of the mouthpiece portion 610.

The blowing member 600 configured as described above blows air into the rubber balloon main body 500 by blowing the air by adding the mouthpiece part 610 to the mouth in a state where the second nozzle member 200 is connected to the connecting part 620. be able to.
When the air is blown, the check valve 650 is pushed into the filter 640 side, but when the mouth is separated from the mouthpiece part 610, the check valve 650 is pushed back to the mouthpiece part 610 side by the air in the rubber balloon body 500. As a result, air does not leak from the rubber balloon body 500.
When the rubber balloon body 500 into which air has been blown is released from the blowing member 600, the pulsating portion 213 of the second nozzle member 200 is pushed out.

  Further, since the filter 640 is incorporated in the blowing member 600, saliva is not blown into the rubber balloon body 500 even if air is blown through the mouth. Therefore, even if the rubber balloon body 500 is caused to fly, there is no risk of spreading a virus that causes infection. In addition, even if the rubber balloon body 500 is ruptured for some reason while air is being blown into the rubber balloon body 500 or held for flight, the virus causing the infection is scattered. There is no fear.

  In addition, the blowing member 600 mentioned above is an example, and it cannot be overemphasized that the blowing member from which a structure differs from this may be used.

In the above-described embodiment, the volume change mechanism 300 is composed of the first serrated portion 130 of the first nozzle member 100 and the second serrated portion 231 of the second nozzle member 200. The present invention is not limited to this.
