And the clip (1) is shown in FIG.
As shown in (1), the balloon (20) is sealed by inserting the mouth tube portion (2) of the balloon between the inner wall surfaces of the pair of sandwiching plate portions (2) and (2). The gap between the inner wall surfaces is smaller than the thickness when the mouth tube portion (21) of the balloon is slightly twisted several times, and the mouth tube portion (21) is densely provided between the inner wall surfaces. It is designed to be pluggable.

As shown in FIG. 2, one of the opposed inner wall surfaces of the sandwiching plate portions (2) and (2) has a ridge (4) at its central portion along the longitudinal direction. Is protruding. On the other hand, a groove (5) corresponding to the ridge is cut out and provided on the other inner wall surface. This groove (5)
Has a width slightly larger than the width of the ridge (4). On the other hand, the ridge (4) protrudes to a position substantially flush with the other inner wall surface, and a portion of the balloon port tube (21) abutting on the ridge (5) is formed in the groove (5). It can be pushed. On the tip end side of the ridge (4), an arc-shaped stopper preventing projection (6) is provided so as to slightly enter the groove (5).

Also, on the front end side of each of these inner wall surfaces, there are provided inclined surfaces (7) (7) formed so as to move away from each other toward the front end, and the mouth tube portion (2) of the balloon is provided.

Stop portions (13) on both inner wall surfaces of the receiving groove (12) that oppose each other to prevent lateral displacement of the clip (1) and prevent the clip (1) from falling out of the receiving groove (12).
(13) (13) (13) is protruded along the vertical direction.

Next, a case where the balloon is sealed using the clip (1) and the mounting device (10) will be described by taking a yo-yo balloon as an example.

First, as shown in FIG. 1, the base member (11)
The clip (1) into the receiving groove (12). And
As shown in FIG. 4 (a), the mouth tube (21) of the balloon was previously twisted several times, and the end of the rubber cord (22) was slightly wound around the mouth tube (21) several times. Pulling the mouth tube (21) of the balloon (20), together with the rubber cord (22)
As shown in (a), the clamping plates (2) and (2) are strongly pushed downward from both tip portions. Then, the mouth tube portion (21) of the balloon is introduced between the opposing inner wall surfaces from the guide inclined surfaces (7) and (7), is crushed flat, and climbs over the retaining prevention protrusion (6). Further, the portion in contact with the ridge (4) is pushed into the groove (5) and is inserted between the inner wall surfaces of the sandwiching plate portions (2) and (2).

From this state, the balloon mouth tube (2)
When the force of the hand that is pulling 2) is released, the balloon port tube (21) extended and inserted between the inner wall surfaces of the holding plate portions (2) and (2) in a thin state becomes longer. As it begins to shrink in the direction and returns to its original thickness, as shown in FIG.
Its outer surface is strongly adhered to both inner wall surfaces of the holding plate portions (2) and (2) and the ridges (4). At this time, the balloon mouth tube (21)
The inner surfaces of the balloons are closely adhered to each other, and the balloon port tube (2
As a result, a sealed state is obtained in which 1) is sandwiched between the inner wall surfaces of the sandwiching plate portions (2) and (2). In this state, when a force is applied to move the balloon port tube section (21) in the length direction or the width direction, the balloon port tube section (21) and the holding plate section (2) ( A strong frictional force is generated between the inner wall surfaces of 2) and the ridges (4), and the clamping plate portion (2) of the balloon port tube portion (21) is formed.
(2) Withdrawal from between is prevented. In particular, since the portion of the balloon port tube (21) in contact with the ridge (4) is bent toward the groove (5), a stronger sealing state can be obtained, and the balloon port tube (21) can be obtained. 3) The lateral displacement in the length direction is reliably prevented.

Next, when the balloon is lifted, the same figure (c)
The clip (1) is also lifted together, as shown in
The balloon sealing operation is completed.

In addition, the opening of the balloon (2
When it is desired to remove the mouth tube portion (21) of the balloon from the clip (1), such as when gas is leaking from 1), hold the clip (1) and hold the mouth tube portion (21) of the balloon. The part (2) is strongly pulled toward the tip of the part (2). Then, the mouth tube portion (21) gets over the retaining prevention projection (6), and the mouth tube portion (21) is taken out from the clip (1).

Further, as shown in FIG. 7 (a), a so-called balloon molding in which four balloons connected in a clover shape are entangled in a bead shape with one thread (23) is used. It is necessary to make two balloons facing each other and seal their mouth pipes as shown in Fig. 2 (b). Even in this case, the clip (1) and the The mounting device (1) is very convenient. Briefly explaining the operation, as shown in FIG. 3 (c), a clip (1) sealing the mouth tube portion (21) of one balloon was inserted into a receiving groove (12) of a base member (11). Leave as it is, and insert the mouthpiece (21) of the other balloon into its clip (1). Then, if these balloons are lifted, the clip (1) is also lifted together as shown in FIG. That is, by using the clip (1) and the attachment device (10), balloons can be attached to the clip (1) one by one, and when forming a balloon molding, of course, a plurality of balloons can be sealed. It is also very convenient when doing.

In the above, one embodiment of the balloon sealing clip and its mounting device according to the present invention has been described.
The present invention is not limited to the case where the yo-yo balloon or the balloon molding described in the above embodiment is created, and may be applied to a case where various rubber balloons into which gas such as air and helium gas is injected are sealed. Of course you can.

[0023]

As described above, according to the first aspect of the present invention, there is provided a balloon closing clip comprising a pair of sandwiching plate portions arranged opposite to each other and a connecting portion integrally connecting both ends of the sandwiching plate portions. Have
Since the mouth tube portion of the balloon is inserted between the opposed inner wall surfaces of the sandwiching plate portion and the balloon is sealed,
After the balloon is inserted between the inner wall surfaces while extending the mouth tube, the force that has been extended is released, and the elastic restoring force of the balloon automatically causes the outer surface of the mouth tube to correspond to the corresponding pinch. While pressing against the inner wall surface and the ridge of the mounting part,
Since the inner surfaces of the mouth tube portions are in close contact with each other, the mouth tube portion of the balloon can be sealed by a simple operation of inserting the balloon mouth tube portion between the opposed inner wall surfaces of the sandwiching plate portion.

In addition, one of the inner wall surfaces is provided with a ridge along the longitudinal direction, while the other is provided with a groove corresponding to the ridge, and the width of the groove is slightly larger than the width of the ridge. Since it is formed in, the portion of the balloon mouth tube portion that abuts on the ridge is pushed into the groove and bent to the groove side,
Since it adheres tightly so as to cover the ridge, a stronger sealing state is obtained, and there is no risk of gas leaking from the balloon, and there is no risk that the clip will unintentionally come off the balloon port tube.

In addition, the clip can be arbitrarily removed from the balloon port tube by an operation reverse to that described above, that is, by strongly pulling the balloon port tube toward the distal end of the holding plate portion. In the event that the clip must be removed from the balloon port after sealing,
The clip can be sealed again using the clip, which is economical.

According to the second aspect of the present invention, since the guide inclined surface is provided on the tip end side of each inner wall surface, the guide is provided when the balloon port tube is inserted between the inner wall surfaces of the holding plate portion. By using the inclined surface portion for use, the balloon mouth tube portion can be very easily inserted between both inner wall surfaces.

According to the third aspect of the present invention, since the arc-shaped protrusion for preventing prevention is provided on the tip end side of the ridge, the balloon port tube portion is formed in the holding plate portion in the closed state. It does not unintentionally escape from between the wall surfaces, and the sealed state can be reliably maintained. Moreover, this retaining prevention projection is
Due to the arc shape, it does not become a major obstacle when inserting the balloon mouth tube between the inner wall surfaces of the sandwiching plate portion or pulling out the balloon mouth tube portion from between the inner wall surfaces of the sandwiching plate portion. The mouth tube portion can relatively easily get over the stopper preventing projection.

According to a fourth aspect of the present invention, there is provided a balloon closing clip mounting device, wherein a receiving groove for the clip is provided at an upper portion, and a stopper for preventing the clip from dropping is provided at an edge of each of inner wall surfaces facing the receiving groove. , The clip can be stably placed in the receiving groove. Therefore, once the clip is placed in the receiving groove, the clip can be attached without touching the clip by grasping the balloon port with both hands, and after mounting, the balloon port is pulled upward. The clip easily comes out of the receiving groove, so that the clip mounting operation can be performed reliably and quickly.

Further, in order to create a balloon mall, 2
In a case where the balloons are opposed to each other and the mouth tube portions are sealed so as to be joined together, a clip is attached to one balloon in the attaching operation, and then the clip is left in the receiving groove. It can be easily performed by inserting the balloon mouth tube portion into the same clip.
