Referring to
As shown in
The film forming part 4 is comprised of an annular member 5 and a fixing member 6 which holds the annular member 5 and fits the film forming part 4 to a connecting part 7 which will be described later on. The annular member 5 is made of a synthetic resin and is formed in ring shape so as to have a generating hole 5b. In addition, grooves 5a are radially formed on the whole annular member 5. The grooves 5a keep the soap solution 9 on themselves and supply the soap solution 9 to the generating hole 5b sequentially to form bubble films.
The fixing member 6 is formed by forming a thin stick into a spiral shape, both ends of the thin stick are attached to the peripheral surface of the annular member 5 so as to hold the annular member 5 with each ends. The fixing member 6 is made from a synthetic resin thin stick or a long and thin metal stick which is covered with a synthetic resin. The fixing member 6 is a mounting member which is used for mounting the film forming part 4 to the connecting part 7, and the fixing member 6 adjusts flow rate of soap solution 9 which flows into the connecting part 7 and also adjusts the amount of soap solution 9 so as not to attach too much soap solution 9 to the annular member 5. The shape of the fixing member 6 is not limited to the spiral shape described above as long as the annular member 5 is stably connected to the connecting part 7, for example, bundled thin sticks can be used by holding the annular member 5.
The connecting part 7 is a hollow tubular member which both ends are opened and is made of a flexible material. Thermoplastic resins are preferably used as the flexible material, including a vinyl chloride resin, a polypropylene resin, a polyethylene resin, and an ABC (Acrylonitrile butadiene styrene) resin etc. In the invention, flexible vinyl chloride resin and flexible polypropylene resin are preferably used.
A female screw part 7a which is screwed onto the male screw part 8a of the liquid container 2 is formed on the inside of one end of the connecting part 7, the connecting part 7 is detachably fit to the liquid container 2 by screwing the female screw part 7a onto the male screw part 8a of the liquid container 2. The fixed member 6 of the film forming part 4 is inserted to the other end of the connecting part 7, whereby the annular member 5 of the film forming part 4 is fixed so as to protrude from the connecting part 7. In this way, the soap solution 9 within the liquid container 2 can flow to the annular member 5 of the film forming part 4 through the interior of connecting part 7.
Since the bubble generating tool 1 of the invention has the pinhole 3 which is small enough so that the soap solution 9 does not flow out on the bottom part 2a of the liquid container 2 which the soap solution 9 is filled, the bubble generating tool 1 is rotated centering on the liquid container 2, the soap solution 9 flow little by little to the film forming part 4 by a centrifugal force and then the bubble film is formed in the generating hole 5b of the film forming part 4.
In the invention, the film forming part 4 and the connecting part 7 can be integrally formed each other. In this instance, the film forming part 4 can be formed only with the annular member 5 and the annular member 5 is integrally formed at the distal end of the connecting part 7. By arranging the annular member 5 on the connecting part 7 so as to orthogonalize to the inner diameter of the connecting part 7, the soap solution 9 which flows through the connecting part 7 can be surly flown to the annular member 5 and the bubble film of the soap solution 9 can be formed in the generating hole 5b. In this instance, by integrally forming the film forming part 4 and the connecting part 7 without the fixing member 6, the processes of manufacturing can be reduced and therefore the cost of manufacturing can be reduced.
As shown in

Then, the soap solution 9 within the liquid container 2 flows to the annular member 5 of the film forming part 4 through the connecting part 7 by a centrifugal force, and the bubble film is formed on the generating hole 5b of the annular member 5. While keeping to rotate the bubble generating toy 10, bubbles continuously generate from the bubble film which is formed on the generating hole 5b by the wind pressure occurred by rotations.
When the bubble generating toy 10 is rotated centering on the rear end side of the liquid container 2 as described above, as shown in
