[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described based on the illustrated embodiments of the present invention. First, the balloon body 1 is formed of a plastic sheet or rubber as a raw material, and is formed in a hollow structure having airtightness so that a gas such as helium or air can be inserted therein to inflate three-dimensionally. The shape of the balloon body 1 in the inflated state is free and may be a disk shape as in the illustrated embodiment, but may be any other shape. The whole or a part of the balloon main body 1 can be made transparent, semi-transparent, colored transparent, or the like so as to have translucency. Also, a picture of a character or the like can be displayed on the surface of the balloon body 1 by printing or the like.

The balloon body 1 has an inner bag 2 attached inside. The inner bag 2 is also formed from a plastic sheet, rubber, or the like as a material so as to be airtight. In addition, the shape of the inner bag 2 is also free, and it can be a straight tube shape as in the illustrated embodiment, or a bag shape (not shown). The inner bag 2 is provided with a gas inlet 3 and a gas outlet 4 at two places.

The inner bag 2 is attached so as to be located inside the balloon body 1, and its gas inlet 3 is opened outside the balloon body 1, and its gas outlet 4 is opened inside the balloon body 1. Let me. The position where the gas outlet 4 is provided in the inner bag 2 is arbitrary, and for example, it can be provided near the tip of the inner bag 2 as in the illustrated embodiment.

The inner bag 2 is provided with a check valve 5. The check valve 5 has a function of enabling a gas to flow into the balloon body 1 and a function of preventing a gas from flowing from the inside of the balloon body 1 to the outside. This check valve 5 is preferably provided near the gas inlet 3 of the inner bag 2 as in the illustrated embodiment.

The inner bag 2 can be fixed by connecting the upper end thereof to the balloon main body 1 as in the illustrated embodiment, but can also be shaken in a free state.

In order to inflate the balloon body 1, a gas such as helium or air is sent from the air inlet 3 of the inner bag 2 opened to the outside of the balloon body 1. The gas flowing into the inner bag 2 passes through the inside of the inner bag 2, flows out of the gas outlet 4, and flows into the inside of the balloon body 1. When gas flows into the balloon body 1, the check valve 5 is opened. When the inside of the balloon body 1 is filled with gas, the balloon body 1 is in an inflated state. Since the check valve 5 is closed, the gas inside the balloon main body 1 does not flow back to the outside through the gas inlet 3 of the inner bag 2. Accordingly, leakage of gas from the balloon body 1 is prevented, and the inflated state is maintained.

By emitting light inside the balloon body 1 or generating sound from the inside of the balloon body 1, the interest can be increased. In this case, the light emitting body 6, the sounding body, etc. The action device can be housed inside the inner bag 2. A lead wire 7 connected to an action device such as a luminous body 6 is protruded from the gas inlet 3 of the inner bag 2 to the outside of the balloon main body 1 so as to be provided with a switch 9 as in the illustrated embodiment. It can be connected to a battery (not shown) built in the grip 8. In order to avoid exposing the lead wire 7 between the balloon body 1 and the grip 8 as in the illustrated embodiment, a pipe-like rod (not shown) is attached to the balloon body 1. It is also possible to adopt a structure in which the lead wire 7 passes through the inside of the rod.

When the luminous body 6 is housed as an action device inside the inner bag 2, the whole or a part of the inner bag 2 is formed of a translucent material, and the whole or a part of the balloon body 1 is also formed. It is formed of a translucent material.

Further, inside the inner bag 2, a shift preventing device 10 of an action device or the like can be provided.

Incidentally, the balloon body 1 and the inner bag 2 need to be joined by welding or the like. When the welding or the like is performed, it is usual that the balloon body 1 and the inner bag 2 are overlapped in a flat state. However, if the both ends of the inner bag 2 are joined to the balloon main body 1 by welding or the like, when the balloon main body 1 is inflated in the completed state, the balloon main body 1 has a length perpendicular to the expanding direction. However, since the length of the inner bag 2 in the same direction is hardly reduced, there is a problem that the inner bag 2 is loosened and the appearance is not good. In order to prevent the loosening of the inner bag 2 from occurring, the balloon body 1 may be inflated, that is, the balloon body 1 may be three-dimensionally joined to the inner bag 2. Such a manufacturing method is extremely difficult to implement. Therefore, there is a demand for a balloon toy having a structure in which the inner bag 2 has no slack inside the inflated balloon main body 1 and is easy to manufacture. As a method of manufacturing such a balloon toy, for example, when the balloon body 1 is inflated and the inner bag 2 is loosened, a part of the inner bag 2 is pulled out of the balloon body 1. One possible method is to stretch the inner bag 2 inside the balloon body to take up slack. Specifically, before the balloon body 1 is inflated, the balloon body 1 is immersed inside the balloon body 1. When the balloon body 1 is inflated and the inner bag 2 becomes loose, the outside of the balloon body 1 is removed. A configuration is conceivable in which a length adjuster 11 that can eliminate slack of the inner bag 2 inside the balloon main body 1 by pulling out the inner bag 2 is provided in a part of the inner bag 2. For example, as shown in FIG. 2A, the length adjusting portion 11 is provided with a navel portion 12 which is recessed inward of the balloon main body 1 in a part of the balloon main body 1, and attaches the inner bag 2 to the navel portion 12. Can be provided by bonding to a position at the back of That is, in the inner bag 2, a portion corresponding to a portion from the entrance of the navel portion 12 to the joining position at the back of the navel portion 12 is the length adjusting portion 11. If such a length adjusting portion 11 is provided, as shown in FIG. 2B, when the balloon body 1 is inflated and the inner bag 2 becomes loose, a part of the inner bag 2, As shown in FIG. 2C, by pulling out the adjusting portion 11 to the outside of the balloon main body 1 while inverting the navel portion 12 together with the navel portion 12, the inner bag 2 inside the balloon main body is stretched to loosen the slack. Can be eliminated. With such a structure, the bonding of the balloon body 1 and the inner bag 2 by welding or the like can be performed in a flat state. That is, the balloon body 1 is not formed in a three-dimensional shape. Manufacturing can be facilitated.

[Effect of the invention]

 The balloon toy according to the present invention according to the first aspect of the present invention has a luminous element inside the inner bag 2 with the check valve 5 attached to the balloon body 1 to allow the gas to flow into the balloon body 1 and inflate the balloon body 1. Since an action device such as 6 can be accommodated, a gas inlet with an air valve is provided in a part of the balloon body as in the conventional example, and the action device is housed in another place of the balloon body. Since there is no need to attach the inner bag and only the process of attaching the inner bag 2 to one position of the balloon body 1, there is an advantage that the number of processes is reduced and the manufacturing cost can be reduced. Further, the balloon toy according to the present invention described in claim 2 can prevent the inner bag 2 from being loosened inside the inflated balloon body, and can be easily manufactured. Further, in the balloon toy according to the present invention described in claim 3, the length adjusting portion 11 can be easily provided in the inner bag 2.
