Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection port of a gas injection valve of a balloon toy which inflates by injecting a gas such as air, floats in the atmosphere, and plays.

2. Description of the Related Art As shown in FIG. 5, a conventional balloon toy formed of a flexible resin sheet having heat bonding property is formed by bonding a pair of resin thin films having at least one surface to be heat bonding. A balloon toy in which a flat cylindrical valve body 4 made of a resin film is attached to a main body opening 3 provided on a part thereof, and the peripheral edge line is thermally bonded to each other so that the surfaces of the balloons face each other so as to face each other. It is used, but when injecting a gas such as air or hydrogen or helium, the balloon toy main body 1 and the flat cylindrical valve body 4 are both thin and flexible, so that when the valve body opening 3 is opened, stable holding is performed. However, it was difficult to take time for the injection operation. In order to improve this, a rigid plate 7 provided with a nozzle insertion circular hole 6 is attached so that the nozzle insertion circular hole 6 overlaps the valve element opening 3 of the flat cylindrical valve element 4. The flat cylindrical valve body 4 is provided with a retaining property and the tip of the gas injection nozzle is inserted through the nozzle insertion circular hole 6.
A balloon toy is used to reach the mouth.
However, the valve element opening 3 of the flat cylindrical valve element 4 exposed to the nozzle insertion circular hole 6 of the rigid plate 7 is formed by cutting the outer portion of the flat cylindrical valve element 4 into a single character. The inner and outer portions of the valve body opening 3 were in close contact with each other.

[Problems to be Solved by the Invention] The valve opening 3 of the conventional flat cylindrical valve 4 for gas injection is obtained by simply cutting the portion of the rigid plate 7 located at the circular hole 6 for nozzle insertion. When the gas injection nozzle is inserted into the valve body opening 3 to inject gas into the balloon toy body 1, the outer edge of the valve body opening 3 made of an extremely thin resin film is The gas injection nozzle is inserted into the valve body opening 3 and is made of a flat cylindrical valve body 4 which is flexible, is of the same color and is of the same color, and is difficult to catch because it is in close contact with the resin film on the rear facing wall of the rear wall or is slightly swung. It was difficult to inject gas into the interior. Further, if the tip of the gas injection nozzle is formed sharp, there is a risk that the valve body opening 3 may be damaged even if the insertion operation is reduced.

[Means for Solving the Problems]
The conventional drawbacks are improved, and the injection port of the balloon toy is made easy and quick to insert the gas injection nozzle, and the main body opening of the balloon toy body composed of a flexible resin sheet having thermal adhesiveness A flat cylindrical valve body having a valve body opening is hermetically bonded by a sealing line to a rigid plate having a nozzle insertion hole, and the nozzle insertion hole is provided in the valve body opening. In the balloon toy main body adhered so as to overlap, at the position of the main body opening, a main body tongue-shaped terminal formed by cutting a part of the balloon toy main body is provided, and a tip of the flat cylindrical valve body is provided. A valve body tongue-shaped terminal formed by cutting the side edge of the portion is provided, and both ends are folded outward at the overlapping fold line to fix the outer edge of the valve body opening to the body tongue-shaped terminal and the valve. The tongue-shaped terminal, and the nozzle insertion It is intended to expose the folding line portion use the circular hole.

[Action] In the present invention, the main body tongue terminal 8 of the balloon toy main body and the valve body part tongue terminal 3 of the flat cylindrical valve body 4 are overlapped and bent outward to form the flat cylindrical valve body 4. Since the outer edge of the valve body opening 3 is formed and the bent end of the valve body opening 3 is exposed in the nozzle insertion circular hole 6, the rigid plate 7 is exposed in the nozzle insertion circular hole 6. Since the outer edge of the valve body opening 3 is thick and strong and has a rounded fold at the tip, when inserting the gas injection nozzle,
The outer edge of the valve body opening 3 is easily opened, the insertion becomes extremely easy, and the efficiency of the gas injection operation is improved.

[Embodiment] An embodiment of the present invention shown in FIGS. 1 and 2 will be described. In the main body opening 2 of the balloon toy main body 1 made of a flexible resin sheet having thermal adhesion,
A flat cylindrical valve body 4 made of a resin film having thermal adhesive properties is hermetically bonded by a sealing seal line 5 and a resin rigidity having a nozzle insertion circular hole 6 in the balloon toy body 1 outside thereof. The plate 7 is attached so that the nozzle insertion hole 6 overlaps the valve body opening 3. FIG. 1 shows the rigid plate 7 separately from the balloon toy main body 1 in order to clarify the structure, but the rigid plate 7 is shown by an A-D excluding a tip portion and a nozzle insertion circular hole 6 portion. The part is attached to the balloon toy body 1. In the illustrated portion B-C, the balloon toy main body 1 and the flat cylindrical valve body 4 are hermetically bonded by a sealing seal line 5.

As shown in FIGS. 3 and 4, a part of the balloon toy main body 1 located at the nozzle insertion circular hole 6 of the rigid plate 7 is cut off at the gas injection port configured as described above. The formed main body tongue-shaped terminal 8 and the outer pieces of two valve body part tongue-shaped terminals 9 formed by cutting the side edges of the ends of the flat cylindrical valve body 4 are overlapped with each other to insert a circular hole for nozzle insertion. At the position of the folding line 10 exposed at the six portions, the sheet is bent outward and fixed. Therefore, the outer edge of the valve body opening 3 of the flat cylindrical valve body 4 exposed in the nozzle insertion circular hole 6 of the rigid plate 7 is formed by the body part tongue terminal 8 and the valve body tongue terminal 9 of the balloon toy body 1. It has a strong dual structure, and its outer edge is bent and rounded to facilitate insertion of the gas injection nozzle.

According to the present invention, both the balloon toy main body and the flat cylindrical valve body are each formed of a thin film, but the valve body opening is formed by a main body tongue terminal and a valve body tongue terminal. Are folded and fixed, so that the edge is made up of four pieces, and the easily damaged edge has sufficient thickness and rigidity to be strong, and the folds are rounded. The tip of the gas injection nozzle that has reached through the nozzle insertion circular hole can be smoothly inserted into the cylindrical cavity of the flat cylindrical valve body without deviating outside the mouth.
