Description

[Technical Field]

[0001] The present invention relates to a soap bubble device and a soap bubble generating method, and more particularly to a soap bubble device and a soap bubble generating method that can easily generate beautiful multiple soap bubbles. [Background technology]

[0002] Soap bubble toys capable of generating soap bubbles have been widely known up until now, and among them, there are soap bubble toys capable of generating one or more soap bubbles within one soap bubble, so-called multiple or composite soap bubbles.

[0003] For example, Patent Document 1 discloses an "instrument for easily making multiple bubbles" that is made up of multiple bubble members each with annular rings of different sizes, and that connects the bubble members with spaces between them so that the rings are parallel to each other. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3225426 Summary of the Invention [Problem to be solved by the invention]

[0005] To make soap bubbles, the ring portion must be immersed in soap bubble liquid so that the soap bubble liquid adheres to the ring portion in the form of a film. In the device described in Patent Document 1, multiple bubble members are connected horizontally and soap solution must be applied to each ring. Therefore, soap solution must be prepared in a bucket-like container that can fit each ring, and the ring members must be immersed in the soap solution before use, requiring a large amount of soap solution. The more soap members are connected, such as in three or four layers, the larger the soap solution container must be horizontally in order to immerse each parallel-arranged ring member in soap solution, and an even larger amount of soap solution is required.

[0006] To minimize the amount of bubble solution, one option is to prepare a tall container that can fit the ring part. In this case, the entire ring part is inserted into the tall container and the bubble solution is applied to the ring part. However, as the child makes and plays with bubbles, the bubble solution gradually decreases and the liquid level drops. In order to immerse the entire ring part in the bubble solution, the bubble solution must be kept at a constant level, and the solution must be replenished many times. Another option is to apply the liquid to each ring part one by one, but this takes time and effort.

[0007] 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 peripheries of the large and small rings, which can result in the bubble liquid as a whole taking on a truncated cone shape. If air is sent into this state, connected bubbles shaped like dumplings or caterpillars will be created, and it will not be possible to create multiple bubbles with bubbles inside bubbles.

[0008] Furthermore, experiments by the applicant have shown that when the rings are on the same plane, connected soap bubbles are formed, and multiple soap bubbles cannot be formed.

[0009] To provide a bubble generating tool that does not require a large amount of bubble liquid, does not require frequent refilling of the bubble liquid, and uses a relatively small amount of bubble liquid, can apply the bubble liquid only to the ring part in one operation, and allows anyone to easily make multiple bubbles. [Means for solving the problem]

[0010] The bubble making device of the present invention is composed of a plurality of bubble making members (10, 20) each having a shaft (11, 21) with a ring portion (12, 22) at one end, the shaft (11, 21) of each of the bubble making members (10, 20) being flexible, the ring portions (12, 22) of each of the bubble making members (10, 20) being different in size, and the ring portion (12) of one of the bubble making members (10) being The surface including the ring portion (12) of one of the soap bubble generating members (10) and the surface including the ring portion (22) of the other soap bubble generating member (20) are positioned at an angle with a gap between them, and each of the shafts (11, 21) bends with a part of the ring portion (12, 22) as a fulcrum, so that the surface including the ring portion (12) of the one soap bubble generating member (10) and the surface including the ring portion (22) of the other soap bubble generating member (20) overlap and become substantially flush with each other.

[0011] The bubble generating member (10, 20) may be configured to include a gripping portion (50) for gripping the other ends of the shafts (11, 21) of the bubble generating members (10, 20) together, such that when force is applied to the shafts (11, 21) with the gripping portion (50), the shafts (11, 21) bend with part of the ring portion (12, 22) as a fulcrum, so that the surface including the ring portion (12) of the one bubble generating member (10) and the surface including the ring portion (22) of the other bubble generating member (20) overlap and become substantially flush, and when the application of force is stopped, the shafts (11, 21) return to their original shape.

[0012] 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 region of the ring portion (12) of the first soap bubble generating member (10), so that the surfaces become substantially flush with each other.

[0013] An attachment (70) having a ring portion (72) may be provided detachably on the bubble generating member, and the size of the ring portion (72) of the attachment may be different from the size of each of the ring portions (12, 22) of the bubble generating members (10, 20). When the attachment is attached to the bubble generating member, the surface including the ring portion (72) of the attachment may be positioned at an angle and spaced apart from the surface including the ring portion of the bubble generating member to which the attachment is attached.

[0014] 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) comprising 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 collectively 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) being flexible, the ring portions (12, 22) of each of the soap bubble generating members (10, 20) being different in size, and the surface including the ring portion (12) of one of the soap bubble generating members (10) and the ring portion (12) of another of the soap bubble generating members (20) being different in size from each other. The surfaces including the ring portions (12, 22) are positioned at an angle to each other with a gap between them, and by applying force to each of the shafts (11, 21) with the gripping portion while a part of the ring portions (12, 22) is in contact with the bottom of a dish containing bubble solution, each of the shafts (11, 21) is bent, and the surface including the ring portion (12) of one of the soap bubble generating members (10) and the surface including the ring portion (22) of the other soap bubble generating member (20) overlap and become substantially flush, so that each of the ring portions (12, 22) is entirely immersed in the bubble solution, and by ceasing application of force, each of the shafts (11, 21) returns to its original shape, causing the bubble solution to adhere to each of the ring portions (12, 22). [Effects of the Invention]

[0015] 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. They can make multiple bubbles with a relatively small amount of bubble liquid. Furthermore, the bubble liquid can be applied in a single motion with one hand, allowing anyone to easily make multiple bubbles. Furthermore, by preventing a film of bubble liquid from forming between the ring parts that generate each bubble and the outer periphery of the ring parts, the bubble liquid can be prevented from forming a truncated cone shape overall, and the bubble liquid can be applied only to the ring parts, allowing beautiful multiple bubbles to be produced stably.

[0017] Embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are merely illustrative and are not intended to exclude various modifications or applications of techniques not explicitly described below. That is, the present invention can be implemented in various modifications (e.g., by combining the various embodiments) as long as the effects thereof are achieved. Furthermore, in the following description of the drawings, identical or similar parts are denoted by identical or similar reference numerals. The drawings are schematic and do not necessarily correspond to actual dimensions, ratios, etc. Parts in the drawings may have different dimensional relationships or ratios. Furthermore, to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art, detailed descriptions of already well-known matters and redundant descriptions of substantially identical configurations may be omitted.

[0018] Fig. 1 is a side view of a bubble making device 100 according to an embodiment of the present invention, and Fig. 2 is a schematic perspective view of the bubble making device 100. The bubble making device 100 of the present invention is composed of a plurality of bubble making 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 making members 10, 20 is flexible, the ring portions 12, 22 of each of the bubble making members 10, 20 are different in size, the surface including the ring portion 12 of one of the bubble making members 10 and the surface including the ring portion 22 of the other of the bubble making members 20 are positioned at an angle to each other with a gap between them, and when each of the shafts 11, 21 flexes with part of the ring portions 12, 22 as a fulcrum, the surface including the ring portion 12 of one of the bubble making members 10 and the surface including the ring portion 22 of the other of the bubble making members 20 overlap and become approximately flush.

[0019] The bubble making device 100 of this embodiment includes two bubble making members 10 and 20 and a grip part 50. A bubble generating member 10, which is an example of one 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, it is preferable to use a shape-memory material that returns to its original shape when no force is applied, such as a graphite or carbon pipe material used in fishing rods, or a tightly wound coil spring.

[0020] The ring portion 12 is used to hold the bubble solution in a film form. It may be made of any material that is resistant to the bubble solution, such as metal, non-ferrous metal such as aluminum, resin, wood, bamboo, or cloth. To enhance the holding power of the bubble solution film, cloth may be wrapped around the outer periphery of the ring to make it easier to hold the bubble solution. It may also be constructed by wrapping a string around the surface of a core material such as wire. The ring surface may also be formed with irregularities or tiny protrusions. While the example of the bubble tool 100 of this embodiment shows the ring portion 12 as being annular (circular), any shape is acceptable as long as it can hold the bubble solution by capillary action. It may be any shape, including square, triangular, or crescent.

[0021] 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. The same configuration of the shaft 21 as that of the shaft 11 will not be described here. The same configuration of the ring portion 22 as that of the ring portion 12 will not be described here.

[0022] The size of the ring portion 12 of the bubble generating member 10 is different from the size of the ring portion 22 of the bubble generating member 20. In this embodiment, the size of the ring portion 22 is smaller than the size of the ring portion 12.

[0023] The grip part 50 is for an operator to grip and operate the bubble making device 100. The grip part 50 is configured so that the other ends of the shafts 11, 21 of the bubble making members 10, 20 can be gripped together.

[0024] Before and after applying the bubble liquid to the ring parts 12 and 22, when air is sent to generate bubbles, that is, when no external force is applied to the shafts 11 and 21, 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 are positioned at an angle with a gap between them.

[0025] A biasing member may be provided in section 60 between shafts 11 and 21 to maintain a predetermined angle or greater between shafts 11 and 21 extending from grip portion 50. The predetermined angle is preferably, for example, approximately 15 to 30 degrees. Note that the predetermined angle is not limited to this range, but may be set depending on the material of the bubble solution, the materials used for shafts 11, 21 and ring portions 12, 22, the flexibility of shafts 11, 21, and the material of the biasing member, if any, used in section 60, as long as it is an angle that prevents a film from forming between the outer peripheries of ring portions 12 and 22, resulting in a continuous truncated cone-shaped film, and ensures that multiple bubbles are neatly generated by the soap bubbles generated by each ring portion 12, 22. The biasing member may be, for example, a coil spring, a leaf spring, or an elastic body such as rubber or sponge.

[0026] When applying bubble liquid to the ring parts 12, 22, the shafts 11, 21 bend 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 inside the ring part 12 of the bubble generating member 10, so that the surfaces become substantially flush. In this case, it is preferable that the ring parts 12 and 22 form concentric circles, as this allows for more stable generation of multiple soap bubbles.

[0027] 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. 4(A) to 4(C) are explanatory diagrams showing the state in which the ring portions 12 and 22 are immersed in the bubble solution. Place a shallow dish (similar to a flowerpot tray) on a flat surface and fill it with bubble solution. 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.

[0028] As shown in Figures 4(A) to 4(C), by operating the gripping part 50 to bring part of the ring parts 12, 22 into contact with the bottom of a dish containing bubble solution, and then applying force from the side of the bubble generating member 20 to the side of the bubble generating member 10, the shafts 11, 21 will bend, allowing the ring parts 12, 22 to be immersed in the bubble solution.

[0029] Specifically, first, the part of the ring part 12 that abuts against the bottom of the dish becomes the fulcrum 12a, and the shaft 11 begins to bend (Figs. 4(A) and (B)). 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, and the entire ring part 12 is immersed in the soap bubble solution. Also, part of the ring part 22 becomes the fulcrum 22a, and the bending of the shaft 21 progresses, and the ring part 22 becomes immersed in the soap bubble solution (Fig. 4(C)). 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 solution. When immersing the ring portion 22 in the bubble solution, 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 solution.

[0030] Next, the bubble making device 100 is lifted by the gripping portion 50 to release the ring portions 12, 22 from the bubble solution. When the force applied to the shafts 11, 21 is stopped, the shafts 11, 21 return to their original, unflexed state (shape), and a distance is created between the ring portions 12, 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 with a gap between them, returning to the state shown in Figures 1 and 2.

[0031] Next, air is sent from the side of the smaller ring part 22 to the side of the larger ring part 12, so that soap bubbles are generated independently from each of the ring parts 12, 22, and a double soap bubble is generated, with the small soap bubble generated by the smaller ring part 22 contained within the large soap bubble generated by the larger ring part 12.

[0032] Even if a film of bubble liquid forms between the outer peripheries of ring portion 12 and ring portion 22 immediately after the bubble liquid is applied and begins to form a truncated cone shape, there is a distance and angle between the surface including ring portion 12 and the surface including ring portion 22. Therefore, if bubble tool 100 is lifted so that ring portions 12, 22 are facing up, the bubble liquid forming a film between the outer peripheries of ring portion 12 and ring portion 22 will drip down toward grip portion 50, causing the film to burst and preventing the truncated cone shape from continuing. The same is true when ring portions 12, 22 are held facing down. In other words, the bubble liquid forming a film between the outer peripheries of ring portion 12 and ring portion 22 will drip down to the edge of the ring portions, causing the film to burst and preventing the truncated cone shape from continuing. Therefore, only the films of the ring portions 12 and 22 remain, and only beautiful double-layered soap bubbles are generated.

[0033] With the bubble making device 100 of this embodiment, it is only necessary to prepare a shallow tray with a volume of bubble liquid equivalent to the height of the rings, so a large amount of bubble liquid is not required, and frequent refilling of the bubble liquid is not necessary, making it possible to make multiple bubbles with a relatively small amount of bubble liquid. Also, since the bubble liquid can be applied to each of the rings 12, 22 by bending the shafts 11, 21, it can be applied in one motion with one hand, making it easy for anyone to make multiple bubbles.

[0034] 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, which prevents the formation of a film of soap bubble liquid between the outer peripheries of the ring portions 12 and 22 and prevents the soap bubble liquid from becoming a truncated cone shape as a whole. Because the soap bubble liquid can be applied only to the ring portion, beautiful multiple soap bubbles can be generated stably.

[0035] 4(A) to 4(C) show an example in which force is applied from the side of the bubble generating member 20 to the side of the bubble generating member 10, and the ring part 12 is first dipped into the bubble solution, but force may also be applied from the side of the bubble generating member 10 to the side of the bubble generating member 20, and the ring part 22 may first be dipped into the bubble solution. It is sufficient that both the ring parts 12 and 22 are immersed in the bubble solution.

[0036] 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 members is not limited. It is sufficient that the shafts can be bent to immerse the ring parts in the bubble solution in the dish, and the number of shafts can be adjusted appropriately depending on the materials used for the shafts and ring parts, the flexibility of the shafts, operability, etc.

[0037] 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 insertable and detachable in the gripping part 50.

[0038] To generate multiple bubbles, the bubble maker 100 may be used by an operator holding the grip 50 and blowing air from the side of the smaller ring portion 22 to the side of the larger ring portion 12, or by an operator holding the grip 50 and, taking into consideration the flow of wind, swinging the bubble maker 100 in an arc in a direction that blows air from the side of the smaller ring portion 22 to the side of the larger ring portion 12.

[0039] In the above-described embodiment, an example was described in which two bubble generating members 10 and 20 were used to create double bubbles, but if an additional bubble generating member is provided, triple or more bubbles can also be created. FIG. 5 is a side view of a bubble making device 200 for producing triple bubbles.

[0040] The bubble making device 200 is configured to include three bubble making members 10, 20, and 30. The configurations of the bubble making members 10 and 20 are similar to that of the bubble making device 100, and therefore a description thereof will be omitted.

[0041] 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. The same configuration of the shaft 31 as that of the shaft 11 will not be described here. The same configuration of the ring portion 32 as that of the ring portion 12 will not be described here.

[0042] The gripping part 50 grips the other ends of the shafts 11, 21, 31 of the bubble generating members 10, 20, 30 together. The sizes of 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 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.

[0043] When applying bubble liquid to the ring portions 12, 22, 32, the shafts 11, 21, 31 bend with parts of the ring portions 12, 22, 32 as fulcrums, 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 approximately flush.

[0044] 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 solution. The process of immersing ring portions 12, 22, and 32 in the bubble solution is the same as the operation of bubble tool 100 described using Figures 4(A) to 4(C), so a detailed description will be omitted.

[0045] When the bubble making device 200 is lifted to remove the ring portions 12, 22, and 32 from the bubble solution, the shafts 11, 21, and 31 return to their original, unflexed state, and distance is again created between the ring portions 12, 22, and 32. 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 with a distance between them, returning to the state shown in FIG.

[0046] Next, air is sent from the smaller ring portion 32 side to the larger ring portion 12 side, whereby independent soap bubbles are generated from each of the ring portions 12, 22, 32, and the second largest soap bubble generated by the second largest ring portion 22 enters into the largest soap bubble generated by the largest ring portion 12, and further the smallest soap bubble generated by the smallest ring portion 32 enters into the second largest soap bubble, thereby generating triple soap bubbles.

[0047] If the bubble generating members 10, 20, 30 are configured to be detachable, the number and size of the overlapping bubbles can be changed, thereby expanding the range of ways to play with soap bubbles. For example, if the shafts 11, 21, 31 are configured to be detachable in the grip 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, and the number of overlapping bubbles, size of the soap bubbles, etc. can be changed while playing.

[0048] (Application example) Any bubble generating member may be provided with a detachable 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.

[0049] The attachment 70 has a ring portion 72 at one end of a shaft 71 for holding the bubble solution in a film form. In the example shown in the figure, the shaft 71 is detachably attached to the attachment mounting part 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 that of the ring portions 12 and 22 will not be described.

[0050] When the attachment 70 is attached to the soap bubble generating member 20, the surface including the ring part 22 of the soap bubble generating member 20 and the surface including the ring part 72 of the attachment 70 are configured to be positioned at an angle with a gap between them.

[0051] If shaft 71 of attachment 70 is made of a flexible material, when applying bubble solution to ring portions 12, 22, 72, shafts 11, 21, 71 bend with portions of ring portions 12, 22, 72 as fulcrums, causing the plane including ring portion 12, the plane including ring portion 22, and the plane including ring portion 72 to overlap and become substantially flush. With ring portion 72 nearly contained within ring portion 22 and ring portion 22 nearly contained within ring portion 12, ring portions 12, 22, 72 are all immersed in the bubble solution.

[0052] 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 with the bubble generating member 10 side facing down when applying bubble liquid to the ring portions 12, 22, 72. Therefore, by applying force to the bubble generating members 20, 10 with the attachment 70 side facing down, the shafts 11, 21 will bend with parts of the ring portions 22, 12 as fulcrums, and the planes including the ring portions 12, 22, and 72 will overlap and become approximately 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, and all of the ring portions 12, 22, 72 will be immersed in the bubble liquid.

[0053] Alternatively, the distance between the surface including the ring part 22 of the bubble generating member 20 and the surface including the ring part 72 of the attachment 70 may be configured to be at least shorter than the distance from the bottom of the dish containing the bubble solution to the liquid surface. This allows the ring part 72 to be immersed in the bubble solution no matter which side is dipped into the bubble solution from, i.e., no matter when force is applied with the bubble generating member 10 side facing down.

[0054] After applying bubble liquid to each of the ring parts 12, 22, 72, air is sent from the side of the smaller ring part 72 to the side of the larger ring part 12, whereby 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 into the largest bubble generated by the largest ring part 12, and further the smallest bubble generated by the smallest ring part 72 enters into the second largest bubble, thereby generating triple bubbles.

[0055] 6, 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. However, 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.

[0056] 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 portions 12 and 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 portions 72 and 22. In this case, the sizes of the ring portions 72 are configured to be larger in order of the ring portions 22, 12, 72.

[0057] The size of the bubble making devices 100, 200, and 300 does not matter. Relatively large bubble making devices 100, 200, and 300, for example, with a total length of approximately 50 cm to 100 cm, allow users to enjoy generating large, multiple bubbles in a large space. Furthermore, bubble making devices 100, 200, and 300 with a total length of approximately 15 cm to 30 cm, for example, allow even small children to easily handle them, allowing users to generate compact, multiple bubbles at hand.

[0058] The scope of application of the present invention is not limited to the above-described 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 that can generate multiple bubbles. [Explanation of symbols]
