Description

The present invention relates to a bubble making device and a bubble making method for making soap bubbles, and in particular to a bubble making device and a bubble making method for making beautiful multiple soap bubbles easily.

Conventionally, bubble toys capable of generating bubbles have been widely known, and among them, there are bubble toys capable of generating so-called multiple or compound bubbles, that is, generating one or more bubbles within one bubble.

For example, Patent Document 1 discloses an "instrument for easily making multiple bubbles" that is made up of multiple bubble members each equipped with annular rings of different sizes, and that connects the bubble members at intervals so that the rings are parallel to each other.

Utility Model Registration No. 3225426

To make soap bubbles, the ring part must be immersed in soap bubble liquid so that the soap bubble liquid forms a film on the ring part.
In the device described in Patent Document 1, the bubble liquid must be applied to each ring part while multiple bubble members are connected horizontally. Therefore, the bubble liquid must be prepared in a bucket-like container that can accommodate each ring part, and the ring parts must be immersed in the bubble liquid before use, which requires a large amount of bubble liquid. The more bubble members are connected in triplicate or quadruplicate, the larger the bubble liquid container must be in the horizontal direction in order to immerse each parallel-arranged ring part in the bubble liquid, and an even larger amount of bubble liquid is required.

To minimize the amount of bubble liquid, one could, for example, prepare a tall container that the ring part would fit into. In this case, the entire ring part would be inserted into the tall container and the bubble liquid would be applied to the ring part. However, as the user plays with making bubbles, the amount of bubble liquid would gradually decrease and the liquid level would drop. To keep the entire ring part immersed in the bubble liquid, the liquid level must be kept constant, and so the liquid would have to be replenished many times. Another option would be to apply the liquid to each ring part one by one in turn, but this would be time-consuming and labor-intensive.

Furthermore, in the case of the device described in Patent Document 1, because the rings are kept parallel to each other, a film of bubble liquid also forms between the outer circumferences of the large and small rings, and the bubble liquid as a whole can take on a truncated cone shape. If air is sent in this state, connected bubbles resembling balls or caterpillars will be created, and it is not possible to create multiple bubbles with bubbles inside bubbles.

Furthermore, in experiments conducted by the applicant, it was found that when the rings are on the same plane, linked soap bubbles are similarly produced, and multiple soap bubbles cannot be produced.

The present invention was made in response to these problems, and aims to provide a bubble generating device that does not require a large amount of bubble liquid, does not require frequent refills of the liquid, and uses a relatively small amount of bubble liquid, can apply the bubble liquid only to the ring part in one action, and allows anyone to easily make multiple bubbles.

The bubble generating device of the present invention is composed of a plurality of bubble generating members (10, 20) each having a shaft (11, 21) with a ring portion (12, 22) at one end, and is provided with a gripping portion (50) for collectively gripping the other end of each of the shafts (11, 21) of each of the bubble generating members (10, 20). Each of the shafts (11, 21) of each of the bubble generating members (10, 20) is flexible, the ring portions (12, 22) of each of the bubble generating members (10, 20) are different in size, and a surface including the ring portion (12) of one of the bubble generating members (10) and a surface including the ring portion (22) of the other of the bubble generating members (20) are spaced apart from each other and form an angle. When a force is applied to each of the shafts (11, 21) with the gripping portion (50) and with a part of the ring portion (12, 22) in contact with the bottom of a dish containing soap bubble liquid, each of the shafts (11, 21) bends with a part of the ring portion (12, 22) as a fulcrum, so that a surface including the ring portion (12) of the one of the soap bubble generating members (10) and a surface including the ring portion (22) of the other of the soap bubble generating members (20) overlap and become substantially flush with each other, so that each of the ring portions (12, 22) is entirely immersed in the soap bubble liquid, and when the application of force is stopped, each of the shafts (11, 21) returns to its original shape and the soap bubble liquid is attached to each of the ring portions (12, 22) .

When the surface including the ring portion (12) of the first soap bubble generating member (10) and the surface including the ring portion (22) of the second soap bubble generating member (20) overlap and become substantially flush with each other, the ring portion (22) of the second soap bubble generating member (20) may be positioned in the inner area of the ring portion (12) of the first soap bubble generating member (10) so that the surfaces become substantially flush with each other.

An attachment (70) having a ring portion (72) may be provided so as to be detachably attached to the bubble generating member, the size of the ring portion (72) of the attachment being different from the size of each of the ring portions (12, 22) of the bubble generating members (10, 20), and when the attachment is attached to the bubble generating member, the surface including the ring portion (72) of the attachment may be configured to be positioned at an angle to the surface including the ring portion of the bubble generating member to which the attachment is attached, with a gap therebetween.

The soap bubble generating method of the present invention is a soap bubble generating method using a soap bubble device (100), the soap bubble device 100 is provided with a plurality of soap bubble generating members (10, 20) each having a shaft (11, 21) with a ring portion (12, 22) at one end, and a gripping portion (50) for gripping the other end of each of the shafts (11, 21) of each of the soap bubble generating members (10, 20), the shafts (11, 21) of each of the soap bubble generating members (10, 20) are flexible, the ring portions (12, 22) of each of the soap bubble generating members (10, 20) are different in size, and a surface including the ring portion (12) of one of the soap bubble generating members (10) and a surface including the ring portion (12) of the other soap bubble generating member (20) are arranged in a plane that faces the surface of the soap bubble generating member (10) and the surface including the ring portion (12) of the other soap bubble generating member (20). The surfaces including the ring portion (22) are positioned at an angle to each other with a gap between them. When a part of the ring portion (12, 22) is placed against the bottom of a dish containing bubble liquid, and a force is applied to each of the shafts (11, 21) with the gripping portion, the shafts (11, 21) are bent, and the surface including the ring portion (12) of the first bubble generating member (10) and the surface including the ring portion (22) of the second bubble generating member (20) overlap and become substantially flush with each other, and the entire ring portion (12, 22) is immersed in the bubble liquid. When the application of force is stopped, the shafts (11, 21) return to their original shape, and the bubble liquid is attached to each of the ring portions (12, 22).

The bubble making device and bubble making method of the present invention do not require a large amount of bubble liquid, and do not require frequent refills of the bubble liquid, and can make multiple bubbles with a relatively small amount of bubble liquid. Also, the bubble liquid can be applied in one motion with one hand, so anyone can easily make multiple bubbles. Furthermore, by preventing the formation of a film of bubble liquid between the ring parts that generate each bubble and the outer periphery of the ring parts, it is possible to prevent the bubble liquid from taking on a truncated cone shape as a whole, and it is possible to apply the bubble liquid only to the ring parts, so beautiful multiple bubbles can be stably produced.

Fig. 1 is a side view of a bubble tool 100 according to an embodiment of the present invention. Fig. 2 is a schematic perspective view of the bubble tool 100.
The bubble generating device 100 of the present invention is composed of a plurality of bubble generating members 10, 20 each having a shaft 11, 21 with a ring portion 12, 22 at one end, and each of the shafts 11, 21 of the bubble generating members 10, 20 is flexible, the ring portions 12, 22 of each of the bubble generating members 10, 20 are different in size, the surface including the ring portion 12 of one of the bubble generating members 10 and the surface including the ring portion 22 of the other of the bubble generating members 20 are positioned at an angle to each other with a gap between them, and each of the shafts 11, 21 flexes with a part of the ring portions 12, 22 as a fulcrum, so that the surface including the ring portion 12 of one of the bubble generating members 10 and the surface including the ring portion 22 of the other of the bubble generating members 20 overlap and become substantially flush with each other.

The bubble generating device 100 of this embodiment includes two bubble generating members 10 and 20 and a grip portion 50 .
A bubble generating member 10, which is an example of a bubble generating member, comprises a shaft 11 having a ring portion 12 at one end.
The shaft 11 is made of a flexible material, for example, a graphite or carbon pipe material used in fishing rods, a coil spring, or other shape-memory material that returns to its original shape when no force is applied.

The ring portion 12 is for holding the bubble liquid in a film. Any material may be used as long as it is resistant to the bubble liquid, such as metal, non-ferrous metal such as aluminum, resin, wood, bamboo, or cloth. To increase the retention of the film of bubble liquid, cloth may be wrapped around the outer circumference of the ring to make it easier to hold the bubble liquid. A core material such as wire may be wrapped with octopus thread. The ring surface may be uneven or have very small protrusions. In the example of the bubble tool 100 of this embodiment, the ring portion 12 is illustrated as being annular (circular), but any shape is acceptable as long as it can hold the bubble liquid by capillary action. Any shape is acceptable, including square, triangular, and crescent shapes.

The bubble generating member 20, which is an example of another bubble generating member, includes a shaft 21 having a ring portion 22 at one end. Note that a description of the same configuration of the shaft 21 as that of the shaft 11 will be omitted. A description of the same configuration of the ring portion 22 as that of the ring portion 12 will be omitted.

The size of the ring portion 12 of the bubble generating member 10 and the size of the ring portion 22 of the bubble generating member 20 are different from each other. In this embodiment, the size of the ring portion 22 is smaller than the ring portion 12.

The gripping part 50 is for an operator to grip and operate the bubble generating device 100. It is configured so that the other ends of the shafts 11, 21 of the bubble generating members 10, 20 can be gripped together.

Before and after applying bubble liquid to the rings 12 and 22, when air is pumped in to generate bubbles, i.e., when no external force is applied to the shafts 11 and 21, the surface including the ring 12 of the bubble generating member 10 and the surface including the ring 22 of the bubble generating member 20 are positioned at an angle to each other with a gap between them.

A biasing member may be provided in the portion 60 between the shaft 11 and the shaft 21 so that the shaft 11 and the shaft 21 extending from the grip portion 50 are kept apart by a predetermined angle or more. The predetermined angle is preferably, for example, about 15 degrees to 30 degrees. The predetermined angle is not limited to this range, but may be set according to the material of the bubble liquid, the material used for the shafts 11, 21 and the ring portions 12, 22, the degree of flexibility of the shafts 11, 21, and the material used for the biasing member if there is one in the portion 60, so long as the angle is an angle at which a film is stretched between the outer circumferences of the ring portions 12 and 22 and a truncated cone-shaped film does not continue, and multiple soap bubbles are neatly generated by the soap bubbles generated by each of the ring portions 12 and 22. The biasing member may be, for example, a coil spring, a leaf spring, or an elastic body such as rubber or sponge.

When applying bubble liquid to the ring parts 12, 22, the shafts 11, 21 flex with parts of the ring parts 12, 22 as fulcrums, so that the surface including the ring part 12 of the bubble generating member 10 and the surface including the ring part 22 of the bubble generating member 20 overlap and become substantially flush. More specifically, the ring part 22 of the bubble generating member 20 is positioned in the inner region of the ring part 12 of the bubble generating member 10, so that the respective surfaces become substantially flush. At this time, it is preferable that the ring parts 12 and 22 form concentric circles. This is because multiple soap bubbles can be generated more stably.

A bubble generating method using the bubble making device 100 of this embodiment will be described below.
FIG. 3 is an explanatory diagram showing the ring portions 12 and 22 immersed in the bubble solution, and FIGS. 4A to 4C are explanatory diagrams showing the state in which the ring portions 12 and 22 are immersed in the bubble solution.
Prepare a shallow dish (about the size of a flowerpot saucer) filled with bubble solution on a flat surface. The size of the dish should be large enough to fit the rings inside, specifically, it should be slightly larger than the diameter of the larger ring 12.

As shown in Figures 4(A) to 4(C), by manipulating the gripping portion 50 to bring a part of the ring portions 12 and 22 into contact with the bottom of a dish containing bubble liquid, and applying force from the bubble generating member 20 side to the bubble generating member 10 side, the shafts 11 and 21 bend, allowing the ring portions 12 and 22 to be immersed in the bubble liquid.

Specifically, first, a part of the ring part 12 that abuts against the bottom of the dish becomes the fulcrum 12a and the shaft 11 starts to bend (FIGS. 4A and 4B). When further force is applied from the side of the soap bubble generating member 20 toward the side of the soap bubble generating member 10, the shaft 11 bends further, the entire ring part 12 is immersed in the soap bubble liquid, and a part of the ring part 22 becomes the fulcrum 22a, further bending the shaft 21, and the ring part 22 is immersed in the soap bubble liquid (FIG. 4C). As shown in FIG. 3, the ring part 22 is almost contained within the inner region of the ring part 12, and both the ring parts 12 and 22 are immersed in the soap bubble liquid.
When immersing the ring portion 22 in the bubble liquid, the shaft 21 may be pressed with a finger as shown in FIG. 3 to assist the ring portion 22 in immersing in the bubble liquid.

Next, the bubble making device 100 is lifted by the gripping portion 50 to push the ring portions 12 and 22 out of the bubble liquid. When the application of force to the shafts 11 and 21 is stopped, the shafts 11 and 21 return to their original, unflexed state (shape), and a distance is created between the ring portions 12 and 22 again. In other words, the surface including the ring portion 12 and the surface including the ring portion 22 are positioned at an angle to each other with a gap between them, returning to the state shown in Figures 1 and 2.

Next, air is sent from the smaller ring portion 22 to the larger ring portion 12, so that separate soap bubbles are generated from each of the ring portions 12, 22, and a double soap bubble is generated, with the smaller soap bubble generated by the smaller ring portion 22 contained within the larger soap bubble generated by the larger ring portion 12.

Even if a film of the bubble liquid stretches between the outer circumferences of the ring parts 12 and 22 and begins to form a truncated cone shape immediately after the bubble liquid is applied, there is a distance and an angle between the surface including the ring parts 12 and the surface including the ring parts 22, so when the bubble tool 100 is lifted so that the ring parts 12 and 22 are on top, the bubble liquid stretching between the outer circumferences of the ring parts 12 and 22 drips down to the side of the grip part 50, causing the film to burst and the truncated cone shape not to persist. The same is true when the ring parts 12 and 22 are held on the bottom. In other words, the bubble liquid stretching between the outer circumferences of the ring parts 12 and 22 drips down to the edge of the ring parts, causing the film to burst and not to persist as a truncated cone shape.
Therefore, only the films of the ring parts 12 and 22 remain, and only beautiful double-layered soap bubbles are generated.

According to the bubble making device 100 of this embodiment, it is only necessary to prepare a quantity of bubble liquid in a shallow dish that is approximately the height of the ring parts, so a large amount of bubble liquid is not required, and frequent refills of the bubble liquid are not required, and multiple layers of bubbles can be made with a relatively small amount of bubble liquid. In addition, the bubble liquid can be applied to each of the ring parts 12, 22 by bending the shafts 11, 21, so the bubble liquid can be applied in one movement with one hand, and anyone can easily make multiple layers of bubbles.

Furthermore, when air is blown in to generate soap bubbles, the surface including the ring portion 12 of the soap bubble generating member 10 and the surface including the ring portion 22 of the soap bubble generating member 20 are not parallel to each other but are positioned at an angle. This prevents the soap bubble liquid from forming a film between the outer peripheries of the ring portion 12 and the ring portion 22, and prevents the soap bubble liquid from forming a truncated cone shape as a whole. Since the soap bubble liquid can be applied only to the ring portion, beautiful multiple soap bubbles can be stably generated.

In this embodiment, an example is shown using Figs. 4(A) to 4(C) in which a force is applied from the bubble generating member 20 side to the bubble generating member 10 side, and the ring portion 12 is first dipped in the bubble liquid. However, a force may be applied from the bubble generating member 10 side to the bubble generating member 20 side, and the ring portion 22 may be first dipped in the bubble liquid. It is sufficient that both the ring portions 12 and 22 are immersed in the bubble liquid.

In this embodiment, the bubble generating member 10 has two shafts 11, and the bubble generating member 20 has one shaft 21, but the number of shafts constituting the bubble generating member is not limited. It is sufficient that the shaft can be bent so that the ring part can be immersed in the bubble liquid in the dish, and this is adjusted appropriately depending on the material used for the shaft and ring part, the flexibility of the shaft, operability, etc.

The bubble generating members 10, 20 may be configured to be detachable from the bubble generating device 100. For example, the shafts 11, 21 may be configured to be removable from the gripping portion 50.

When generating multiple bubbles, the bubble device 100 can be used by an operator holding the grip 50 and blowing air from the smaller ring portion 22 side to the larger ring portion 12 side, or by an operator holding the grip 50 and, taking into account the wind flow, swinging the bubble device 100 in an arc in a direction that blows air from the smaller ring portion 22 side to the larger ring portion 12 side.

In the above embodiment, an example was described in which two bubble generating members 10, 20 were used to create double bubbles. However, if an additional bubble generating member is provided, triple or more layered bubbles can also be created.
FIG. 5 is a side view of a bubble making device 200 for producing triple bubbles.

The bubble making device 200 is composed of three bubble making members 10, 20, and 30. The configuration of the bubble making members 10 and 20 is similar to that of the bubble making device 100, so a description thereof will be omitted.

The bubble generating member 30 is an example of another bubble generating member, and includes a shaft 31 having a ring portion 32 at one end. Note that a description of the same configuration of the shaft 31 as that of the shaft 11 will be omitted. A description of the same configuration of the ring portion 32 as that of the ring portion 12 will be omitted.

The gripping portion 50 grips the other ends of the shafts 11 , 21 , 31 of the bubble generating members 10 , 20 , 30 collectively.
The ring portion 12 of the bubble generating member 10, the ring portion 22 of the bubble generating member 20, and the ring portion 32 of the bubble generating member 30 are different in size from one another. In the example of Fig. 5, the ring portion 22 is smaller than the ring portion 12, and the ring portion 32 is smaller than the ring portion 22.

When applying bubble liquid to the ring portions 12, 22, 32, the shafts 11, 21, 31 flex with a part of the ring portion 12, 22, 32 as a fulcrum, so that the surface including the ring portion 12 of the bubble generating member 10, the surface including the ring portion 22 of the bubble generating member 20, and the surface including the ring portion 32 of the bubble generating member 30 overlap and become substantially flush.

When ring portion 32 is almost entirely contained within ring portion 22, and ring portion 22 is almost entirely contained within ring portion 12, ring portions 12, 22, and 32 are all immersed in the bubble liquid. The process of immersing ring portions 12, 22, and 32 in the bubble liquid is similar to the operation of bubble tool 100 described using Figures 4(A) to 4(C), so a detailed description will be omitted.

When the bubble making device 200 is lifted to remove the ring portions 12, 22, and 32 from the bubble liquid, the shafts 11, 21, and 31 return to their original, unflexed state, and a distance is created between the ring portions 12, 22, and 32 again. In other words, the surface including the ring portion 12, the surface including the ring portion 22, and the surface including the ring portion 32 are positioned at an angle to each other with a gap between them, returning to the state shown in FIG. 5.

Next, air is sent from the smaller ring section 32 to the larger ring section 12, so that independent soap bubbles are generated from each of the ring sections 12, 22, 32, and the second largest soap bubble generated by the second largest ring section 22 enters the largest soap bubble generated by the largest ring section 12, and further the smallest soap bubble generated by the smallest ring section 32 enters the second largest soap bubble, creating a triple soap bubble structure.

If the bubble generating members 10, 20, 30 are configured to be detachable, the number and size of the overlapping bubbles can be changed, expanding the range of ways to play with bubbles. For example, if the shafts 11, 21, 31 are configured to be removable in the gripping part 50, the bubble generating members 10, 20, 30 can be easily attached and detached by simply inserting and removing the shafts 11, 21, 31, allowing the number of overlapping bubbles, the size of the bubbles, etc. to be changed while playing.

(Application example)
Any of the bubble generating members may be provided with a removable attachment.
6 is a side view of the bubble making device 300. The bubble making device 300 has a configuration in which an attachment 70 is provided to the bubble making member 20 of the bubble making device 100 described above.

The attachment 70 has a ring portion 72 at one end of a shaft 71 for holding the bubble liquid in a film form.
In the example shown in the figure, a shaft 71 is detachably attached to an attachment mounting portion 81 of the soap bubble generating member 20 .
The size of the ring portion 72 is smaller than that of the ring portion 22. Regarding the ring portion 72, the same configuration as the ring portions 12 and 22 will not be described.

When the attachment 70 is attached to the bubble generating member 20, the surface including the ring portion 22 of the bubble generating member 20 and the surface including the ring portion 72 of the attachment 70 are configured to be positioned at an angle to each other with a gap between them.

When the shaft 71 of the attachment 70 is made of a flexible material, when the bubble liquid is applied to the ring portions 12, 22, 72, the shafts 11, 21, 71 flex with a part of the ring portions 12, 22, 72 as a fulcrum, so that the surface including the ring portion 12, the surface including the ring portion 22, and the surface including the ring portion 72 overlap and become substantially flush. With the ring portion 72 nearly contained within the ring portion 22, and the ring portion 22 nearly contained within the ring portion 12, the ring portions 12, 22, 72 are all immersed in the bubble liquid.

If the shaft 71 of the attachment 70 is not made of a flexible material, the attachment 70 will not bend even if force is applied to the bubble generating member 10 side when applying bubble liquid to the ring portions 12, 22, 72. Therefore, by applying force to the bubble generating member 20, 10 side with the attachment 70 side facing down, the shafts 11, 21 bend with a part of the ring portions 22, 12 as a fulcrum, and the surface including the ring portion 12, the surface including the ring portion 22, and the surface including the ring portion 72 overlap and become approximately the same surface, so that the ring portion 72 is almost contained within the ring portion 22, and the ring portion 22 is almost contained within the ring portion 12, and all of the ring portions 12, 22, 72 are immersed in the bubble liquid.

Alternatively, the distance between the surface including the ring portion 22 of the bubble generating member 20 and the surface including the ring portion 72 of the attachment 70 may be configured to be shorter than the distance from the bottom of the dish containing the bubble liquid to the liquid surface. This allows the ring portion 72 to be immersed in the bubble liquid no matter which side is dipped into the bubble liquid from, i.e., no matter when force is applied with the bubble generating member 10 side facing down.

After applying bubble liquid to each of the ring parts 12, 22, 72, air is sent from the smaller ring part 72 side to the larger ring part 12 side, so that independent bubbles are generated from each of the ring parts 12, 22, 72, and the second largest bubble generated by the second largest ring part 22 enters the largest bubble generated by the largest ring part 12, and further the smallest bubble generated by the smallest ring part 72 enters the second largest bubble, generating triple bubbles.

In the example of FIG. 6, an example was described in which the attachment 70 is provided on the bubble generating member 20 so that the ring portion 22 is located between the ring portion 12 and the ring portion 72, but the attachment 70 may be provided so that the ring portion 72 is located between the ring portion 12 and the ring portion 22. For example, when the ring portion 72 is located between the ring portion 12 and the ring portion 22, the size of the ring portion 72 is configured to be smaller than the ring portion 12 and larger than the ring portion 22.

The attachment 70 may also be attached to the bubble generating member 10. For example, when the attachment 70 is attached to the bubble generating member 10 so that the ring portion 72 is located between the ring portion 12 and the ring portion 22, the size of the ring portion 72 is configured to be smaller than the ring portion 12 and larger than the ring portion 22. Alternatively, the attachment 70 may also be attached to the bubble generating member 10 so that the ring portion 12 is located between the ring portion 72 and the ring portion 22. In this case, the size of the ring portion 72 is configured to be larger in the order of the ring portions 22, 12, 72.

The size of the bubble making devices 100, 200, 300 does not matter. A relatively large bubble making device 100, 200, 300, for example with a total length of about 50 cm to 100 cm, allows users to enjoy generating large multiple bubbles in a large space. Also, a bubble making device 100, 200, 300, for example with a total length of about 15 cm to 30 cm, which is easy for even small children to handle, allows users to generate multiple bubbles of a compact size at hand.

The scope of application of the present invention is not limited to the above-mentioned configuration. Three or more bubble generating members may be provided. The present invention can be widely applied to bubble generating devices and bubble generating methods capable of generating multiple bubbles.
