Description

  The present invention relates to a light emitting balloon in which a light emitter is disposed inside a balloon and emits light toward the outside, and a method for manufacturing the same.

  Traditionally, in traditional festivals and events, synthetic rubber balloons are sold and distributed in addition to traditional rubber balloons. These balloons made of synthetic resin have gained popularity, especially among children, with pictures of popular characters drawn on the surface and devised shapes.

  By the way, these balloons can visually recognize the picture and shape drawn on the surface in a bright place in the daytime, but when the surroundings become dark from evening to night, the picture and shape drawn on the surface can also be visually recognized. In addition, children's enjoyment was halved because they could not make use of the pictures and shapes that they had devised.

On the other hand, Patent Document 1 describes an invention relating to a light-emitting balloon in which a chemiluminescent material is inserted from the outside into a pocket provided inside a balloon made of a synthetic resin film so as to emit light.
Patent Document 2 describes an invention relating to a light-emitting balloon in which a light-emitting portion that emits light from a battery is provided on a gas-injection valve of a balloon main body that is used when gas is injected to make it light.

  However, in the light-emitting balloon described in Patent Document 1, the position of the pocket into which the light-emitting body is inserted is limited to substantially the center in the balloon body. For this reason, the illuminant can be lit at the central portion in the balloon body, but it cannot be lit at a portion other than the center, and the multiple illuminants cannot be lit at different positions. Moreover, in order to insert the light emitter into the pocket from the outside, it is necessary to attach the pocket to the balloon body in an airtight manner, and processing is difficult.

  Moreover, since the position of the light emitter is also limited to the upper part of the gas injection valve, the light emitter described in Patent Document 2 is placed at other portions in the same manner as the light balloon described in Patent Document 1.

In addition, the luminous body holding bag is placed on one of the two synthetic resin films forming the main body, and the two peripheral edge portions of the synthetic resin film and the both ends of the luminous body holding bag coincide with each other. And the other of the two synthetic resin films that form the main body from above is overlapped, so that if the peripheral edges of the two synthetic resin films are subsequently welded or bonded together, While being formed, both end portions of the light emitter holding bag can be easily attached by being sandwiched between the peripheral portions.

Here, the light emitting balloon of the present invention is “a main body formed by superimposing two synthetic resin films and thermally welding or bonding the peripheral portion”, “a transparent synthetic resin film and both ends sealed. A light-emitting body holding bag having an end sandwiched between the peripheral edges of two synthetic resin films, and a “light-emitting body inserted in the light-emitting body holding bag” The basic feature is that “the light emitter can be arranged at an arbitrary position inside the main body by determining the attachment position of the light emitter holding bag”.
On the other hand, the light-emitting balloons of the inventions described in Patent Document 1 and Patent Document 2 are in common with the present invention in that both have a “light emitter”. Further, the light-emitting balloon of the invention described in Patent Document 1 is common to the present invention in that “the two synthetic resin films are overlapped and the peripheral portion is formed by thermal welding or bonding”.
However, in the light emitting balloons of the inventions described in Patent Document 1 and Patent Document 2, since the mounting position of the light emitter is limited to the central portion of the balloon and the like, the design is limited and the mounting process is also performed. It is not easy. On the other hand, the light emitting balloon of the present invention is configured to attach a light emitter using a light emitter holding bag, and the invention described in Patent Document 1 and Patent Document 2 in terms of the method of attaching the light emitter. The configuration is very different.
And, due to the difference in the configuration, there is a unique effect, which is not in the inventions described in Patent Document 1 and Patent Document 2, that the light emitter can be easily arranged at an arbitrary position inside the balloon. It can be done.

Next, with reference to FIG. 1 thru | or FIG. 8, the light emitting balloon which concerns on Embodiment 1 of this invention, and its manufacturing method are demonstrated. FIG. 1 is a front view showing a light emitting balloon 100 according to Embodiment 1, and FIG. 2 is a side view.
The main body 10 of the light emitting balloon 100 is formed by superposing two synthetic resin films 11 and 12 having the same shape and size, and thermally welding or bonding the peripheral edges 11a and 12a.
As a material of the synthetic resin film, for example, polyethylene, polyamide, polyethylene terephthalate, polypropylene, polyvinyl alcohol, ethylene vinyl alcohol polymer, or the like is used.

A gas inlet 13 is formed in the lower part of the main body 10, and a gas such as helium is injected from the gas inlet 13. The gas injection port 13 is provided with a check valve (not shown) that is closed after the gas injection, so that the injected gas is not ejected.
The main body portion 10 before gas injection is flat with the two synthetic resin films 11 and 12 being in close contact with each other. However, when the gas is injected, two synthetic resin films are formed as shown in FIGS. The films 11 and 12 are separated and swelled.

Next, the internal structure of the main body 10 of the light emitting balloon 100 will be described. FIG. 3 is a front sectional view showing the light emitting balloon 100 according to the first embodiment, and is a sectional view taken along the line BB in FIG. FIG. 4 is an AA enlarged sectional view of FIG.
As shown in FIG. 3, a band-shaped light emitter holding bag 30 is attached inside the main body 10. A light emitter 31 is inserted inside the light emitter holding bag 30 and emits light inside the inflated balloon to light the balloon.

  As shown in FIG. 4, one end 30 a of the light emitter holding bag 30 is sandwiched between the peripheral edges 11 a and 12 a of the two synthetic resin films 11 and 12. The same applies to the other end 30b. Then, the light emitter holding bag 30 is attached to the inside of the main body portion 10 by sandwiching the both end portions 30a and 30b at the two portions X and Y of the peripheral edge portions 11a and 12a of the two synthetic resin films 11 and 12, respectively. It has been. Thus, by attaching the light emitter holding bag 30 to the two locations X and Y of the peripheral portions 11a and 12a, the light emitter holding bag 30 does not easily move inside the balloon after gas injection (so as not to shake). It has become.

In the present embodiment, both end portions 30a and 30b are attached to the laterally extending portions X and Y of the peripheral portion so that the light emitter holding bag 30 is disposed in the horizontal direction inside the main body portion 10. The mounting position of the light emitter holding bag 30 is not particularly limited. For example, the light emitter holding bag 30 may be arranged in the vertical direction, or the light emitter holding bag 30 may be attached to the upper side or the lower side instead of the vertical center of the main body 10.
Thus, the light emitter 31 can be arranged at an arbitrary position inside the main body 10 by freely determining the mounting position of the light emitter holding bag 30.

Next, the structure of the light emitter holding bag 30 and the light emitter 31 will be described. FIG. 5 is a perspective view showing the light emitter holding bag 30, and FIGS. 6 and 7 are front views showing the light emitter holding bag 30.
As shown in FIG. 5, the luminous body holding bag 30 is a cylindrical body made of a transparent synthetic resin film, and the luminous body 31 is inserted from the end portion. As a material of the synthetic resin film, for example, polyethylene, polyamide, polyethylene terephthalate, polypropylene, polyvinyl alcohol, ethylene vinyl alcohol polymer, or the like is used. The “transparent synthetic resin film” includes not only completely transparent but also translucent ones.
The light emitter holding bag 30 has a cylindrical shape with at least one end opened. Then, the light emitter 31 is inserted from this opening.

The light emitter 31 includes an LED (light emitting diode) 31a, a button battery 31b, and a switch 31c. By operating the switch 31c to emit light, the LED 31a emits light toward the outside of the transparent light emitter holding bag 30. Is supposed to be released. The size of the light emitter 31 is smaller than the inner diameter of the light emitter holding bag 30 so that the light emitter 31 can move in the light emitter holding bag 30.
Note that a light bulb or the like may be used for the light-emitting portion of the light-emitting body, but an LED is preferable because it emits a large amount of light and has excellent visibility and consumes less power.
Alternatively, a light sensor may be attached to the light emitter 31 so that it automatically emits light when dark.
In addition, a sensor that reacts to sound is attached to the illuminant 31 so that it automatically emits light when it makes a sound from the outside, or a sensor that reacts to vibration is attached to the illuminant 31 and vibration is automatically applied from outside You may make it light-emit.

As shown in FIG. 6, both ends 30a and 30b of the light emitter holding bag 30 after the light emitter 31 is inserted are sealed. Further, both sides of the inserted light emitter 31 are also sealed to form detents 30 c and 30 d so that the light emitter 31 does not move in the light emitter holding bag 30. In this way, the light emitter 31 is fixed inside the belt-shaped light emitter holding bag 30.
The sealing of the both end portions 30a and 30b and the detents 30c and 30d can be performed by heat welding or adhesion, but it is preferable to perform heat sealing by utilizing a material called a synthetic resin film.
Further, as shown in FIG. 7, the interval between the detents 30e and 30f may be increased so that the light emitter 31 can move between the detents 30e and 30f. By doing so, the design can be changed and enjoyed by moving the light emitter 31 inside the balloon body 10.

Next, a method for manufacturing the light emitting balloon 100 according to Embodiment 1 will be described. FIG. 8 is a perspective view showing a method for manufacturing the light emitting balloon 100 according to the first embodiment.
First, as described above, the light emitter 31 is inserted into the light emitter holding bag 30 made of a cylindrical and transparent synthetic resin film, and both end portions 30a and 30b are sealed. Further, detents 30c and 30d are formed so that the light emitter 31 does not move.

Next, two synthetic resin films 11 and 12 having the same shape and size are prepared, and the luminous body holding bag 30 in which the luminous body 31 is loaded is superimposed on one synthetic resin film 12. At this time, it overlaps so that two places X and Y of the peripheral part 12a of one synthetic resin film 12 and the both ends 30a and 30b of the light-emitting body holding bag 30 may each correspond. That is, the overlapping is performed so that the X portion and the end portion 30a of the peripheral edge portion 12a coincide with each other and the Y portion and the end portion 30b of the peripheral edge portion 12a coincide with each other.
Here, the length of the light emitter holding bag 30 is determined according to the mounting position on the synthetic resin films 11 and 12, but the light emitter holding bag 30 having different lengths is prepared in advance, You may make it use suitably according to an attachment position.

  Next, the other synthetic resin film 11 is further overlapped from above. The synthetic resin film 11 has the same shape and size as the synthetic resin film 12, and overlaps the synthetic resin film 12 without excess or deficiency. And two places X and Y of the peripheral part 11a of the synthetic resin film 11 and the both ends 30a and 30b of the light-emitting body holding bag 30 are made to correspond, respectively.

Next, the peripheral portions 11 a and 12 a of the two synthetic resin films 11 and 12 are heat-welded or bonded to form the main body portion 10. At this time, both end portions 30 a and 30 b of the light emitter holding bag 30 are sandwiched between the peripheral portions 11 a and 12 a and attached to the inside of the main body portion 10.
The joining of the peripheral portions 11a and 12a can be performed by thermal welding or adhesion, but it is preferable to perform thermal welding by utilizing a material called a synthetic resin film.
A gas inlet 13 having a check valve (not shown) is formed below the synthetic resin films 11 and 12.

As described above, according to the light emitting balloon 100 according to the first embodiment, the main body portion 10 of the light emitting balloon 100 overlaps the peripheral portions 11a and 12a by superimposing the two synthetic resin films 11 and 12 or bonding them. It can be easily inflated by injecting gas into the inside.
Moreover, since the light-emitting body holding bag 30 is formed of a transparent synthetic resin film, the light of the light-emitting body 31 inserted therein can be transmitted outward. Moreover, since the both ends 30a and 30b of the cylindrical body are sealed, the light emitting body 31 inserted therein does not jump out.
Further, since both end portions 30a and 30b of the light emitter holding bag 30 are respectively sandwiched at two locations X and Y of the peripheral portions 11a and 12a of the two synthetic resin films 11 and 12, the light emitter holding bag 30 is provided. Can be easily attached to a desired position inside the main body 10.
As described above, the attachment position of the light emitter holding bag 30 can be determined and the light emitter 31 can be arranged at an arbitrary position inside the main body 10, so that various designs according to the difference in the position of the light emitter 31 are possible. Become.

  Further, when the luminous balloon 100 is manufactured, the luminous body holding bag 30 is placed on one of the two synthetic resin films 11 and 12 forming the main body 10, and the peripheral edge of the one synthetic resin film 12. Of the two synthetic resin films 11 and 12 forming the main body portion 10 from above, the two portions X and Y of the portion 12a are overlapped with each other so that both end portions 30a and 30b of the light emitter holding bag 30 are coincident with each other. Since the other 11 is overlapped, if the peripheral portions 11a and 12a of the two synthetic resin films 11 and 12 are then heat-welded or bonded, the main body portion 10 is formed, and both end portions 30a and 30a of the light emitter holding bag 30 are formed. 30b can be easily attached by being sandwiched between the peripheral portions 11a and 12a.

  Further, since the light emitter 31 is an LED, the light emission amount is large, the visibility is excellent, the power consumption is small, and the life of the light emitting balloon 100 can be extended.

  In addition, if a light sensor is attached to the light emitter 31 so that it automatically emits light when it becomes dark, the switch 31c for turning on the light emitter 31 is unnecessary, and light is emitted only when the surroundings are dark and it is desired to improve visibility. Can be made.

Note that when the main body 10 is inflated by injecting gas into the inside, the peripheral portions 11a and 12a of the main body 10 are reduced in diameter toward the center, so that both end portions 30a and 30b of the light emitter holding bag 30 are sandwiched. The distance between the two locations X and Y of the peripheral edges 11a and 12a is reduced.
Therefore, the luminous body holding bag 30 is formed of a material having elasticity, and in a state where the both end portions 30a and 30b are previously pulled and extended, the peripheral portions 11a and 12a of the two synthetic resin films 11 and 12 are formed. It is preferable to sandwich the two locations X and Y, respectively. In this way, as the distance between X and Y is reduced, the light emitter holding bag 30 is also reduced, so that the light emitter holding bag 30 is not loosened inside the main body 10.

In addition, a reinforcing member made of a synthetic resin film is prepared so that the light emitter holding bag 30 does not loosen inside the main body 10, and one end of the reinforcing member is connected to the light emitter holding bag. For example, 30 may be heat-welded or bonded to an intermediate portion, and the other end portion may be sandwiched between the peripheral portions 11 a and 12 a of the two synthetic resin films 11 and 12.
In this way, since the light emitter holding bag 30 can be supported at the three peripheral portions 11a and 12a, the light emitter holding bag 30 is prevented from slackening, and the light emitter holding bag 30 is provided inside the main body 10. The effect that suppresses shaking is obtained.

  Further, in the first embodiment, one light emitter holding bag 30 is attached to the inside of the main body portion 10, but a plurality of light emitter holding bags 30 may be attached. If a plurality of light emitter holding bags are attached to different positions inside the main body, the plurality of light emitters 31 can be arranged and illuminated at different positions inside the main body 10.

Moreover, in the said Embodiment 1, both ends 30a and 30b of the light-emitting body holding bag 30 were each clamped by two places X and Y of the peripheral parts 11a and 12a of the two synthetic resin films 11 and 12, As in a light emitting balloon according to another embodiment shown in FIG. 9, only one end 40 a of the light emitter holding bag 40 may be sandwiched at one place Z of the peripheral portions 11 a and 12 a.
In this way, the luminous body holding bag 40 can be attached more easily, and the luminous body 41 can be shaken in the balloon to enjoy a change in design.

Next, with reference to FIG.10 and FIG.11, the light emission balloon which concerns on Embodiment 2 of this invention, and its manufacturing method are demonstrated. FIG. 10 is a front view showing the light-emitting balloon 200 according to the second embodiment, and FIG. 11 is a front sectional view showing the light-emitting balloon 200 according to the second embodiment.
The light emitting balloon 200 according to the second embodiment has substantially the same configuration as the light emitting balloon 100 according to the first embodiment, but differs in the following points.

As shown in FIG. 10, three transmission parts 251, 252, and 261 are provided on the synthetic resin film 21 that forms the main body part 20 of the light emitting balloon 200. The transmission parts 251, 252, and 261 are transparent or translucent, and are easier to transmit light from the light emitter than the peripheral part. In the second embodiment, the transmission parts 251 and 252 represent the eyes, the transmission part 261 represents the mouth, and the face is represented by the entire balloon.
On the other hand, as shown in FIG. 11, two light emitter holding bags 50, 60 are attached in the vertical direction inside the main body 20 of the light emitting balloon 200. That is, both end portions 50a, 50b of the light emitter holding bag 50 are sandwiched between the peripheral portions 21a, 22a of the two synthetic resin films 21, 22, and similarly, both end portions 60a, 60b of the light emitter holding bag 60 are It is sandwiched between the peripheral portions 21a and 22a.

Inside the luminous body holding bag 50, two luminous bodies 51 and 52 are inserted so as not to move inside. In addition, a single light emitter 61 is inserted into the light emitter holding bag 60 so as not to move inside.
The light emitters 51, 52, 61 are positioned so as to be disposed at opposing positions of the transmission parts 251, 252, 261 provided in the main body part 20. That is, the light emitter 51 is opposed to the transmission part 251, the light emitter 52 is opposite to the transmission part 252, and the light emitter 61 is opposite to the transmission part 262. Here, the opposing position means a position where the luminous body can be seen through the transmission part when the luminous balloon 200 is viewed from the front. In other words, it refers to the position where the illuminant comes directly under the transmission part when the luminous balloon is placed flat.

  As described above, according to the light emitting balloon 200 according to the second embodiment, the main body portion 20 is provided with the transmission portions 251, 252, and 261 that transmit light from the light emitters 51, 52, and 61 more easily than the peripheral portion. Since 51, 52 and 61 are arranged at positions opposite to each other of the transmission parts 251, 252, and 261, the light of the light emitters 51, 52, and 61 can be surely emitted outward from the transmission parts 251, 252, and 261. The design by the light emitters 51, 52, 61 can be made to stand out.
