Some embodiments of the present invention will be described in detail with reference to the accompanying drawings. The stopper 11 shown in FIG. 1 will be described. A plate-like body 30 made of a plastic material or the like is provided with an opening 33, a short columnar attaching portion 23 for attaching a thread and a small opening portion 17, and a plate-like body. A notch 15 is provided that extends from the edge of the body 30 to the small aperture 17. The plate-shaped body 30 can be formed in any shape such as a circular shape, an elliptical shape, or a rectangular shape. However, in the case of a rectangular shape, it is preferable that the corners are rounded to prevent danger. In the stopper 11 of the present invention, the size of each part is somewhat dependent on the size of the balloon, but in general, can be the following values. The long side of the plate-shaped body 30 is 30 to 50 mm,
Short side 15 to 30 mm, thickness 0.5 to 4 mm; opening 33
Diameter of 10 to 15 mm (preferably having a size that allows the mouth of a balloon to easily pass therethrough);
3 has a length of 10 to 20 mm (diameter is generally about 2 to 8 mm); the small opening portion 17 has a diameter of 0.5 to 1.5 mm; the cut 15 has a width of 0.1 to 0.5 mm and a length of 0. 3-1m
m. Further, in order to reduce the weight of the stopper 11, the plate-shaped body 30
It may also be provided with one or more holes (not shown) within a range that does not significantly impair the strength of the.

A method of attaching a balloon to the flat plate-like stopper 11 such as the stopper 11 shown in FIG. 1 will be described with reference to FIGS. 5 to 7 and 8 to 12. As shown in FIG. 5, the mouth portion of the balloon 41 is passed from the upper portion of the plate-shaped body 30 through the opening 33 (or, as shown in FIG. 5, a notch 91 is provided to communicate with the outside from the opening 33, and the mouth portion of the balloon is provided. Can be inserted into the opening 33 through the notch 91). Then, connect the mouth of the balloon to a nozzle such as an air or hydrogen gas generator or blow it with the mouth of the operator to inflate the balloon, and cut the mouth of the balloon as shown in FIGS. 6 and 9-10. It is forcedly passed through the inside of 15 and pushed into the small opening portion 17. It is also possible to put the inflated balloon in the opening 33 of the stopper and perform the above operation. Thus, the use of this stop 11 is very simple, yet the mouth of the balloon is reliably sealed and no gas leaks occur. When the operator blows the balloon to inflate it, the balloon may be inflated and then the mouth of the balloon may pass through the opening 33 of the plate-shaped body 30. It is very convenient that when the balloon is lifted by holding the thread end of the stopper 11 in the hand after the thread is attached by the method described later and the balloon is lifted by the lifting force, the thread is loosened by itself (FIG. 7). In addition, as shown in FIG.
It is also possible to attach a rubber band 76 to the lower end of the thread 75.

The stopper 11 shown in FIG. 1 has the short columnar mounting portion 23 as described above. A notch 71 for threading is also shown in FIG. An example of a method of attaching the thread to the stopper 11 will be described. Mounting part 23 of stopper 11
A tube (for example, a soft vinyl tube) 73 that can be tightly fitted in the tube (for example, a soft vinyl tube) 73 is prepared. The length of the tube 73 may be approximately the same as the length of the mounting portion 23. A thread 75 of approximately the same length as the thread used in a conventional balloon with threads is passed through the tube 73 from the lower side of the tube 73 as shown in FIG. 1, and the front end 77A of the thread is hung on the upper side of the tube. Alternatively, the thread 75 may be passed through the tube from above the tube 73 (FIG. 2). Next, the tube 73 is fitted into the attachment portion 23 of the stopper 11 (see the arrow in FIG. 1), the "remaining portion" of the thread 75 is wrapped around the tube 23, and the portion near the rear end 77B of the thread is stopped. Push it into the notch 71 of 11 and fix it there. The stopper 11 with the thread 75 wound around is attached to the balloon containing a low specific gravity gas such as hydrogen gas or argon gas to close the mouth of the balloon. When using this balloon, the rear end 77 of the thread 75
B is held by hand and removed from the notch 71 of the stopper 11. Due to this detachment, the balloon rises due to its own levitation force, but at this time, since the yarn 55 is loosely unwound from the tube 23, its rotating force causes the balloon to slowly rise and rise, and eventually the yarn 75 alone goes to its front end. Unwind to the area just after 77A. However, since the portion of the thread 75 near the front end 77A is brought into close contact with the mounting portion 23 of the stopper 11 by the pipe 73 as described above, the entire thread is never completely separated from the stopper 11. Absent. In the rubber balloon with a thread shown in this specific example, since the balloon rises slowly and unwinds the thread as described above, the child is strongly attracted,
It has a great effect as a toy. In addition, stop 1
The front end 77A of the thread 75 can be attached to the thread 1 by a method other than those described above, for example, using an adhesive tape.

As is clear from the above description, the rubber balloon stopper of the present invention is very convenient, but its main features are as follows. In other words, the object of gas stopping can be surely achieved by only sandwiching the mouth of the balloon with this stopper without binding it with a string. When making a balloon with a thread, a balloon with a thread can be made without binding the mouth of the balloon with a thread. Also, since the thread is held down by the balloon on the stop, the thread does not leave the stop. The thread wound around the stopper is loosened by itself as the gas balloon rises due to the levitation force, and is easy for an infant to handle. Since the stopper of the present invention can be made of plastic, it is lightweight, the levitation force of the balloon is hardly affected, and it can be used not only for large balloons but also for small balloons. Since only a thin thread is needed, the weight of the thread is very small, and it is not necessary to increase the amount of gas filled in the balloon, and it is possible to put gas into many balloons from one gas cylinder.

As described above, the gas stopper according to the present invention has a simple structure, can be manufactured at low cost, and is durable, and the mouth of the balloon can be easily and surely sealed by one-touch operation. Furthermore, since the mounting portion for mounting the balloon holder can be easily formed, the balloon holder can be easily mounted.
As described above, the present invention has a remarkable effect as compared with the conventional technique.
