SOLUTION: A fastening device 4 is mounted at a mouth part 2 of the body 1 of a balloon while a weight 5 is separably formed integrally on the fastening device 4 and the fastening device 4 is linked to the weight 5 with a string 9. The fastening device 4 and the weight 5 are made separable by bending.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a balloon with a weight.

[0002]

2. Description of the Related Art When a helium gas is charged and then is flown into the air,
Eventually, gas will fall out and fall, contaminating the natural environment, and the string attached to the balloon will be entangled with the bird's feet, etc., or it will be caught on the high voltage electric wire, causing problems and preventing such inconveniences Measures are required.

As one of the methods, a rubber band is attached to the end of a string, and after filling with helium gas, a rubber band is wound around a finger or an arm. However, it is unpleasant to tighten a finger or arm with a rubber band, and the rubber band may come off in some way when being wound around or removed from the finger or arm, and is not very effective.

[0004] Further, a type in which a weight is attached to a balloon is also known, and is sold as a single unit separately from the balloon. If a string of a balloon is tied to this weight, the balloon will not fly over the sky even if the weight is separated from the hand, which is a very effective means. However, tying the string to the weight is cumbersome, and the balloon may fly during this work.Adding the weight to the balloon does not create any interestingness on the balloon itself, so purchase the weight. It was troublesome to attach.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and provides a balloon which does not have the trouble of connecting weights and which can reliably prevent the balloon from freely flying into the air. That is the subject.

[0006]

In order to solve the above-mentioned problems, a balloon according to the present invention has a stopper attached to an opening of a balloon main body and a weight formed integrally with the stopper so as to be separable. The stopper and the weight are connected by a string.

[0007] Instead of integrally forming the stopper and the weight so as to be separable, a configuration may be adopted in which a weight is separably coupled to the stopper.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a balloon body. The balloon body 1 may be a commercially available balloon body. The mouth 2 of the balloon body 1 is attached to a stopper / weight connecting body 3 made of synthetic resin. The stopper / weight connecting body 3 is obtained by integrally connecting the stopper 4 and the weight 5 to each other.
Is formed with a groove 6 for sandwiching the mouth 2 of the balloon after being filled with helium gas, and a protruding shaft 6b for sealing the tip of the mouth 2 so as to prevent gas from leaking. The weight 5 is set to be heavier than the buoyancy of the balloon by helium gas.

The stopper 4 and the weight 5 are formed to be separable by bending. The connecting portion 8 between the stopper 4 and the weight 5 is formed with a thin folding groove 7 for facilitating folding. The stopper 4 and the weight 5 are connected by a string 9. One end of the cord 9 is connected to the opening 14 of the stopper 4, and the other end is fixed to the weight 5 with an adhesive tape 15, and is usually wound around the stopper / weight joint 3.

[0010] The above-mentioned stopper / weight connecting body 3 is attached to the balloon body 1 in advance by filling the inside of the balloon with helium gas and then inserting the stopper 4 into the mouth portion 2 of the balloon to stop. .

When the balloon is purchased, the balloon is always levitated in the air, so that the weight 5 must be separated from the stopper 4. To this end, as shown in FIG. 2, the stopper / weight connecting body 3 is separated from the groove 7 by bending it. Thereafter, the balloon body 1 rises into the air, so that the string 9 extends. The weight 5 may be held in the hand.

As described above, since the weight 5 is attached from the time when the stopper 4 is inserted into the mouth portion 2 of the balloon main body 1 and attached, there is no need to bother the weight 5 to the string 9 and the balloon can be freely moved. Flying into the air can be reliably prevented.

Further, since the weight 5 itself may have a simple structure, it is easy to integrally form the stopper / weight link 3 from synthetic resin, and the manufacturing cost can be reduced.

The connecting portion 8 of the stopper / weight connecting body 3 is not limited to a thin folded groove structure. For example, a perforated structure may be used.

Instead of integrally forming the stopper 4 and the weight 5 so as to be separable, a structure in which the weight 5 is separably coupled to the stopper 4 may be employed. FIG. 3 shows an example of such a case, 4 is a stopper, and 5 is a weight. The stopper 4 is a commercially available one, and includes a cylindrical portion 11 having a valve 10 and a projecting piece 12. Various kinds of stoppers 4 are implemented, and any stopper 4 may be used as long as it seals the mouth 2 of the balloon body 1. The weight 5 is set so as to be heavier than the buoyancy of the balloon by helium gas, as in the above-described example, and an insertion hole 13 is formed at the upper end of the weight 5 for inserting the projection 12 of the stopper 4 and joining the same. ing. One end of the cord 9 may be fixed to the protruding piece 12 of the stopper 4 with a staple or the like, and the other end may be fixed to the surface of the weight 5 with an adhesive tape or the like.

In this case, the mouth portion 2 of the balloon body 1 is expanded and fastened to the flange 16 of the valve 10, and helium gas is filled from the tube portion 11. After filling, the valve closes and the gas inside does not leak. After purchasing the balloons, as shown in Figure 4,
The protruding piece 12 of the stopper 4 may be extracted from the weight 5 and separated.

Also in the above-described example, since the weight 5 is attached from the time when the stopper 4 is inserted into the mouth portion 2 of the balloon body 1 and attached, there is no need to bother the weight 5 to the string 9 and the balloon is free. Floating in the air can be reliably prevented.

Note that the stopper 4 and the weight 5 may be integrally connected and may be separated if necessary, and are not limited to the above-described example. In addition to the connection by insertion, a part of the stopper 4 and a part of the weight 5 may be hooked. A part of the stopper 4 and a part of the weight 5 may be overlapped and wrapped with the string 9 from above the overlapping portion. May be combined.
