Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel gas stopper for preventing loss of gas after inflating a rubber balloon or the like by pressurizing a gas such as air or hydrogen gas.

Conventionally, in the case of toy rubber balloons, the mouth of the balloon was closed by hand after the gas was injected, and then the balloon was attached to a holding rod such as a string or vinyl-covered wire, but this operation was troublesome. , and is time-consuming, so there has been a strong desire to develop a gas stopper that can easily close the mouth of a balloon.

The present invention has been completed in order to completely satisfy the above-mentioned needs. By using the gas stopper of the present invention (hereinafter referred to as the "stopper"), the mouth of a rubber balloon can be easily and reliably sealed. It can be stopped.

The present invention provides a plate-shaped body 30 with an opening 33 and a small aperture 17 having a size sufficient to allow the mouth of a balloon to pass through, and inserts the mouth of a rubber balloon or the like into the opening 33. The thread is forced to pass through the opening and held in the small opening 17, and a tapered short columnar mounting part 23 is integrally provided to attach the thread to hold the balloon or the like, and the thread is attached thereto. Cuts 87, 89 and a hole 81 are provided in the plate-like body 30, and when the balloon is used, by removing the rear end of the thread from the thread attachment cut, the balloon rises, and as it rises, the thread winds itself. This invention relates to a gas stopper for rubber balloons, etc., characterized in that it is configured to be unwound.

In addition, a notch 91 for balloon insertion reaching the opening 33 from the edge of the plate-shaped body 30 is provided,
Preferably, the mouth of the balloon can be inserted into the opening through the notch 91.

The short pillar-shaped attachment portion 23 for attaching the thread can be configured so that the thread can be directly wound thereon.

Some specific examples of the present invention will be described in detail with reference to the accompanying drawings.

The stopper 11 shown in FIG.
7, and a notch 15 extending from the edge of the plate-like body 30 to the small opening 17. Furthermore, as desired, a thread attachment hole 35,
83 may also be provided. The plate-shaped body 30 is circular;
It can be made in any shape such as oval or square, but if it is square, it is better to round the corners to prevent danger. The dimensions of each part of the stopper 11 depend somewhat on the size of the balloon, but generally can have the following values. Long side 30 to 50 of plate-shaped body 30
mm, short side 15-30mm, thickness 0.5-4mm; opening 33
diameter of 10 to 15 mm (preferably large enough to allow the mouth of the balloon to pass through easily); length of the short columnar attachment part 23 of 10 to 20 mm (the diameter is generally 2 to 8 mm)
The diameter of the small opening 17 is 0.5 to 1.5 mm; the width of the notch 15 is 0.1 to 0.5 mm, and the length is 0.3 to 1 mm; the diameter of the thread attachment holes 35 and 83 is 1 to 5 mm. Further, it is also possible to provide a thread attachment groove, that is, a constriction, in the attachment portion 23. Further, in order to reduce the weight of the stopper 11, one or more holes (not shown) may be provided in the plate-like member 30 without significantly impairing its strength.

Figures 5 to 7 show how to attach a balloon to a flat stopper 11 such as the stopper 11 shown in Figure 1.
The explanation will be made with reference to the drawings and FIGS. 8 to 12.
As shown in FIG.
(Alternatively, as shown in FIGS. 3-4 and 8, a notch 91 leading from the opening 33 to the outside is provided, and the mouth of the balloon is passed through the opening 33 through the notch 91.) (It is also possible to put it in the section 33). Next, the balloon is inflated by connecting the mouth of the balloon to a nozzle of an air or hydrogen gas generator or the like, or by blowing with the handler's mouth.
As shown in the figure, the mouth of the balloon is forcibly passed through the notch 15 and pushed into the small opening 17. Also, insert the inflated balloon into the opening 3 of the stopper.
It is also possible to perform the above operation by setting the number to 3.
Thus, the use of this stopper 11 is very simple, and the mouth of the balloon is reliably sealed, with no gas leakage occurring. When the balloon is inflated by the handler blowing it with his or her mouth, the mouth of the balloon may be passed through the opening 33 of the plate-shaped body 30 after the balloon is inflated. After attaching the string using the method described below, if you hold the end of the string of the stopper 11 in your hand and release the balloon, the string will unravel by itself as the balloon rises due to the buoyancy force (Figure 7), which is very convenient. It is. In addition, as shown in FIG. 12, the thread 75
It is also possible to attach a rubber band 76 to the lower end of.

The fastener 11 shown in FIG. 1 has the short columnar attachment portion 23 as described above. If desired, this attachment portion 23 may be provided with a straw-like holder (e.g. approximately 20 mm long).
The straw-shaped holder can be attached extremely easily with a one-touch operation by fitting the opening of the -30cm vinyl tube in the direction of the arrow.

The fastener shown in FIG. 1 will be explained in detail. This is in the form of a plate-shaped body, but its outline is greatly rounded, and the plate-shaped body 30 has an opening 33, and this opening communicates with the outside through a notch 91, and the balloon The mouth part is notched 91
Since the balloon can enter the opening 30 through the opening 30, it is very easy for the balloon to enter. Further, since the peripheral edge is provided with a notch 87 and a notch 89, and a small hole 83 having a notch 85, threads can be conveniently attached as described later.

A tapered, hollow or non-hollow short column-shaped attachment portion 23 is integrally provided on the lower surface of the stopper shown in FIGS. 1 and 2, but this is not for attaching a thread. be.

The method of attaching the thread to the fastener described in FIGS. 1-2 is illustrated in FIGS. 3 and 4. Insert the thread into the hole 83 from the top surface of the stopper (thread starting end 75a), then pass the thread through the small opening 17 at the back of the notch 15 from the bottom surface of the stopper (thread 75b), bring it out from there to the top surface, and then While holding down the thread 75a at the starting end with the thread 75c, thread it through the notch 95 at the back of the opening 33 (thread 75c), bring it out to the bottom again through this notch 95 (thread 75d), and wrap the thread around the short columnar attachment part 23 (thread 75c). 75e), then insert the thread into the cut 89 (thread 75f), bring it out from there and put it into the cut 87 (thread 75g), and lock the end portion 75h of the thread. After attaching the balloon to the stopper, if you hold the end of the string in your hand and remove it from the notches 87 and 89, the balloon will rise as described above, and the string will automatically come off from the attachment part 23 (No. 7).
figure). This thread removal operation is easy even for young children, and the balloon easily rises by the length of the thread. According to this thread attachment method, the starting end 75a of the thread is held down by the middle part 75c of the thread, so that it does not dangle.
Furthermore, the end portion 75h of the thread has notches 87 and 8.
9, which completely prevents thread entanglement and is very convenient when handling a large amount of threaded fasteners.

As is clear from the above description, the rubber balloon stopper of the present invention is very convenient, and its main features are as follows. In other words, the purpose of stopping the gas can be reliably achieved by simply inserting the mouth of the balloon into this stopper without tying it with a string. When making a string balloon, you can make a string balloon without tying the mouth of the balloon with string. Also, since the thread is held down by the balloon on the stopper, the thread will not separate from the stopper. The string wound around the stopper loosens itself as the gas balloon slowly rotates and rises due to the buoyant force, making it easy for even young children to handle. Moreover, as the balloon slowly rotates as it rises and the string unwinds as described above, it strongly attracts the interest of young children and has a unique and great effect as a toy. Since the fastener of the present invention can be made of plastic, it is lightweight and has little effect on the buoyancy of the balloon, allowing it to be used on small as well as large balloons.
Since only a thin thread is required, the weight of the thread is negligible, and there is no need to increase the amount of gas filled into the balloon, allowing more balloons to be filled with gas than one gas cylinder.

As described above, the gas stopper of the present invention has a simple structure, so it can be manufactured at low cost and is durable, and the mouth of the balloon can be easily and reliably sealed with a single touch operation. Furthermore, since the attachment portion for attaching the balloon holder can be easily formed, the attachment of the balloon holder is also easy. As described above, the present invention has particularly remarkable effects compared to the conventional techniques.
