[Detailed configuration of bubble generating device]

With reference to FIGS. 3-8, the detailed structure of the bubble generating apparatus 10 is demonstrated.

3 and 4 show, the fitting portion 20 has a closed annular shape and is fitted to the upper portion of the container 80 . When the foam generating device 10 is mounted on the container 80 , the fitting 20 surrounds the side (outer surface) of the container 80 . The ultrasonic wave generating unit 30 constitutes a part of the fitting portion 20 , and in addition to the function of emitting ultrasonic waves, the foam generating device 10 is attached to the container 80 as a part of the fitting portion 20 . It has a fixing function.

In detail, the fitting part 20 is comprised from the upper end fitting part 21 which is arrange|positioned along the upper end of the container 80, and the ultrasonic wave generating part 30. As shown in FIG. An ultrasonic wave generating part 30 is located between the both ends of the upper end fitting part 21 in the circumferential direction, and the upper end fitting part 21 and the ultrasonic generating part 30 form one ring.

The ultrasonic generator 30 is arranged so as to be in contact with a portion located below the spout 83a among the side surfaces of the container 80 . In other words, when viewed from the direction along the axial direction of the ring constituted by the fitting portion 20 , that is, in the direction opposite to the upper lid portion 83 in the container 80 , the spout among the side surfaces of the body portion 81 . The portion closest to (83a) and the ultrasonic generator 30 are in contact, and the spout 83a and the ultrasonic generator 30 face each other.

The upper end fitting portion 21 is disposed along the upper end of the container 80 , while the ultrasonic generating portion 30 is disposed at a position away from the upper end of the container 80 in the vertical direction. That is, in the axial direction of the ring which the fitting part 20 comprises, the upper end of the ultrasonic generator 30 is located below the upper end of the upper end fitting part 21 with respect to the spout 83a.

5, the container 80 originates in the connection structure of the main body part 81 and the upper lid part 83, and after the diameter becomes small once from the upper end, it has a shape which gradually expands and becomes constant. have. That is, the side surface of the container 80 has the recessed part 81a recessed toward the inside of the container 80 from an upper end. The recessed portion 81a extends along the circumferential direction of the container 80 , and is formed over the entire perimeter of the container 80 .

The upper end fitting portion 21 of the foam generating device 10 is provided with a convex portion 21a protruding radially inward of the upper end fitting portion 21, and the protruding portion 21a has a concave portion ( 81a) has a shape that fits snugly. The convex portion 21a extends along the circumferential direction of the upper end fitting portion 21 . When the foam generating device 10 is mounted on the container 80, the convex portion 21a and the concave portion 81a are fitted.

As FIG. 6 shows, the ultrasonic wave generator 30 is equipped with the ultrasonic wave generator 31 mentioned above, and the ultrasonic wave propagation member 32 spread out in the form of a sheet. The ultrasonic wave propagating member 32 constitutes the inner surface of the ultrasonic wave generator 30 and is in contact with the ultrasonic wave generator 31 . When the bubble generating device 10 is mounted on the container 80 , the ultrasonic wave propagating member 32 abuts against the side surface of the container 80 , and is fitted to the ultrasonic wave generating device 31 and the side surface of the container 80 . Ultrasonic waves emitted by the ultrasonic wave generating device 31 are transmitted to the ultrasonic wave propagating member 32 , and further transmitted from the ultrasonic wave propagating member 32 to the container 80 .

The ultrasonic wave propagating member 32 is made of a material having a flexibility capable of transmitting ultrasonic vibrations in close contact with the ultrasonic wave generator 31 and the container 80 . The ultrasonic wave propagating member 32 is made of, for example, silicone rubber.

The ultrasonic wave propagating member 32 may be connected to the upper end fitting portion 21 . The material constituting the upper end fitting portion 21 is not particularly limited. For example, the upper end fitting portion 21 is made of a material capable of imparting elasticity to the upper end fitting portion 21 to a degree capable of attaching and detaching the upper end fitting portion 21 to and from the container 80 . For example, the upper end fitting portion 21 is made of a resin such as silicone rubber or ABS resin.

The upper end fitting portion 21 and the ultrasonic wave propagating member 32 may be connected after being formed as separate members, and when the upper end fitting portion 21 and the ultrasonic wave propagating member 32 are made of the same material, the upper end fitting portion 21 and the ultrasonic wave propagating member 32 may be formed of the same material. The fitting portion 21 and the ultrasonic wave propagating member 32 may be integrally formed, for example, by press working using a mold or the like. In addition, good transmission of ultrasonic waves from the ultrasonic wave generator 31 to the container 80 is possible even when the ultrasonic wave propagating member 32 is not disposed, such as when the ultrasonic wave generator 31 and the container 80 have good adhesion. In this case, it is not necessary to provide the ultrasonic wave propagating member 32 .

Moreover, in the ultrasonic generator 30, the part which covers the outer side of the ultrasonic generator 31 is comprised from the same material as the upper end fitting part 21, and is continuous from the upper end fitting part 21, for example. is embodied as a structure that becomes For example, in the example shown in FIGS. 1-8, the outer surface of the ultrasonic generator 30 has a curved-surface shape continuous from the upper end fitting part 21, and the ultrasonic generator 30 generates an ultrasonic wave. Depending on the size of the device 31 , it protrudes below the upper end fitting portion 21 . However, the external shape of the ultrasonic generator 30 and the material of the part which covers the outer side of the ultrasonic generator 31 are not specifically limited.

As FIG. 7 shows, the accommodating part 40 which accommodates the drive part 41 and the electric power supply part 42 is the opposite side to the ultrasonic generator 30 with respect to the center line which is the center of the ring which the fitting part 20 comprises. connected to the fitting portion 20. That is, the accommodating part 40 is arrange|positioned with respect to the container 80 on the opposite side to the ultrasonic generator 30 .

The external shape of the accommodating part 40 is not specifically limited, The accommodating part 40 should just have a shape which can accommodate the drive part 41 and the electric power supply part 42. As shown in FIG. For example, the accommodating part 40 has a shape extending downward from the fitting part 20, and accommodates a dry cell exchangeably. Moreover, the wiring which connects the drive part 41 and the electric power supply part 42, and the ultrasonic generator 31 is passing through the inside of the upper end fitting part 21. As shown in FIG.

The operation part 50 is also located on the opposite side to the ultrasonic generator 30 with respect to the center of the ring constituted by the fitting part 20 , that is, on the opposite side to the ultrasonic generator 30 with respect to the container 80 .

As FIG. 8 shows, the operation part 50 is arrange|positioned in the area|region which overlaps with the fitting part 20 along the radial direction of the upper end fitting part 21 among the outer surfaces of the accommodating part 40. As shown in FIG. That is, the operation part 50 is arrange|positioned near the upper end of the container 80.

In addition, since the power supply unit 42 accommodates a battery as a power source, the portion of the bubble generating device 10 in which the power supply unit 42 is located tends to be heavier than the other portions. In the configuration of the first embodiment in which the power supply 42 is disposed on the opposite side to the ultrasonic generator 30 with respect to the container 80 , for example, the ultrasonic generator 31 in the ultrasonic generator 30 is By forming the covering portion thicker than the upper end fitting portion 21 or by including a member for adding weight to the ultrasonic generating portion 30, the balance of weight in the foam generating device 10 can be adjusted by electric power. You may adjust so that it may not be biased too much to the part where the supply part 42 is located.

[How to use the bubble generator]

With reference to FIG. 9 and FIG. 10, the operation|action of the foam generating apparatus 10 is demonstrated, demonstrating how to use the foam generating apparatus 10. As shown in FIG.

When using the foam generating device 10 , the user first mounts the foam generating device 10 to the container 80 . At this time, the user inserts the fitting portion 20 into the container so that the ultrasonic generator 30 comes into contact with the side surface of the container 80 from below the spout 83a of the container 80 . For example, the bubble generating device 10 may be provided with a display urging the user to dispose the ultrasonic wave generating unit 30 below the spout 83a, or in the instructions attached to the bubble generating device 10 or the like. , instructions for disposing the ultrasonic wave generator 30 below the spout 83a may be described. In addition, the spout 83a is opened before or after mounting of the foam generating device 10 .

9 , after mounting the foaming device 10 to the container 80 , the user lifts the foaming device 10 and the container 80 so that the spout 83a is located at the lower side. The foaming device 10 and the container 80 are tilted, and the effervescent beverage in the container 80 flows out from the spout 83a and pours into a glass 90 such as a glass. At this time, the foam generating device 10 is turned off. The user preferably holds the container 80 together with the foam generating device 10 from the side where the receiving portion 40 is located with respect to the container 80 . In this way, the liquid effervescent beverage Lq is mainly poured into the cup 90 .

As shown in FIG. 10 , at the timing when an appropriate amount of the effervescent beverage Lq is poured into the cup 90 , the user operates the operation unit 50 while continuing to pour the effervescent beverage to turn on the foam generating device 10 . switch to For example, when the user is holding the container 80 together with the foam generating device 10 from the side where the receiving part 40 is located with respect to the container 80, the position of the index finger is moved away from the operation part 50 ), the foam generating device 10 can be easily switched from off to on.

Based on the input of the signal from the operation unit 50 , a drive signal is output from the driving unit 41 to the ultrasonic wave generator 31 , whereby the ultrasonic wave generator 31 emits ultrasonic waves. The ultrasonic waves are transmitted to the side of the container 80 through the ultrasonic wave propagating member 32 , and further transmitted to the effervescent beverage in the container 80 .

The effervescent beverage remaining in the container 80 at this point in time is a part of the effervescent beverage initially filled in the container 80 . The effervescent beverage remaining in the container 80 is collected in the vicinity of the spout 83a in the container 80 when the container 80 is inclined. When the container 80 is stationary, if the ultrasonic generator 30 is configured to contact the side surface of the container 80 from below the spout 83a, the container 80 is tilted so that the effervescent beverage is poured from the spout 83a. When placed, the ultrasonic generator 31 is located below the spout 83a, that is, in the vicinity of the portion where the effervescent beverage is collected in the container 80. Therefore, the ultrasonic wave emitted from the ultrasonic generator 31 is accurately transmitted to the effervescent beverage in the container 80 .

In addition, since the ultrasonic wave emitted by the ultrasonic wave generator 31 is transmitted to the container 80 through the ultrasonic wave generator 31 and the ultrasonic wave propagating member 32 in close contact with the side surface of the container 80, in the propagation process The loss of ultrasonic vibration is suppressed, and the transmission efficiency of an ultrasonic wave becomes high.

By ultrasonic vibration, the foamed beverage in the container 80 is foamed, and this foam Fm comes out of the spout 83a and is poured into the cup 90 . Thereby, the foamed beverage in the container 80 can be transferred to the cup 90 so that the foam Fm rises on the liquid foamed beverage Lq in the cup 90 .

Here, in this embodiment, the ultrasonic wave emitted by the foam generating device 10 is transmitted to the foamed beverage in the container 80 from the side surface of the container 80 . Therefore, the foamed beverage is foamed without directly touching the foaming device 10 and poured into the cup 90 . Therefore, since it is not necessary to wash the foam generating apparatus 10 every time it is used, the burden required for management of the foam generating apparatus 10 can be reduced. Moreover, even if the ultrasonic generator 30 is a structure located below the spout 83a, since the ultrasonic generator 30 is separated from the upper end of the container 80, the ultrasonic generator 30 is located below the container 80. Compared with the configuration in contact with the upper end of the , it is difficult for the effervescent beverage flowing out from the spout 83a to adhere to the foam generating device 10 . Therefore, the burden required for management of the bubble generating apparatus 10 can be reduced more.

Further, as a foam generating device compared with this embodiment, a device used to foam the upper portion of the foamed beverage by bringing the ultrasonic generator into contact with the side of the container while the container in which the foamed beverage is placed is still standing. have. However, when the upper part of the foamed beverage put in the container is bubbled by ultrasonic vibration, the vibration is transmitted to the liquid part of the lower part, and carbonic acid is also released from this part, so that the flavor of the foamed drink is easily reduced. Moreover, since a part of the effervescent beverage put in the container becomes foam, the quantity of a liquid part also changes according to the production amount of foam, and the production amount of this foam changes according to the position and time of contact with an ultrasonic generator. Therefore, it is difficult to control the ratio of liquid to foam as desired by the user. Moreover, when the container is opaque, since the amount of bubbles can be confirmed only from above the container, it is more difficult to control the ratio of the liquid to the foam as desired by the user.

On the other hand, if the foam generating device 10 of this embodiment is used, since the foamed beverage poured into the cup 90 first is maintained in a liquid state without receiving vibration, it is possible to suppress a decrease in the flavor of the foamed beverage Moreover, since grasping|ascertaining of the quantity of a liquid part is also easy, control of the ratio of the liquid and foam in a foamed beverage is also easy.

As described above, according to the first embodiment, the following effects can be obtained.

(1) By fitting of the container 80 and the fitting part 20, the ultrasonic wave generating part 30 is arrange|positioned so that it may contact with the side surface of the container 80 from below the spout 83a. Thereby, since the ultrasonic wave emitted by the ultrasonic wave generating unit 30 is transmitted to the foamed beverage in the container 80 from the side surface of the container 80 , the foamed beverage does not directly touch the foaming device 10 , but the container 80 . It foams within and emerges from the spout 83a. Therefore, since it is not necessary to wash the foam generating apparatus 10 every time it is used, the burden required for management of the foam generating apparatus 10 can be reduced.

In addition, since the fitting portion 20 is fitted to the container 80 and surrounds the side surface of the container 80 , compared with a form in which the foam generating device is mounted on the container 80 as if it is mounted above the container 80 , , it is difficult for the foam generating device 10 to come out of the container 80 .

(2) The ultrasonic generator 30 constitutes a part of the fitting portion 20, and is disposed below the spout 83a rather than the upper fitting portion 21 which is another portion of the fitting portion 20. do. Therefore, since the ultrasonic generator 30 is separated from the upper end of the container 80 , it is difficult for the foamed beverage flowing out from the spout 83a to adhere to the foam generating device 10 . Thereby, the burden required for management of the bubble generating apparatus 10 can be reduced more.

(3) Since the fitting portion 20 has a shape that can be fitted into the container 80, which is a beverage can, when the user drinks the effervescent beverage contained in the commercially available beverage can, the foaming device 10 is inserted into the beverage can. ) can be directly installed and used. Therefore, for example, compared with the case where a dedicated container is required for use of the foam generating apparatus 10, the versatility of the foam generating apparatus 10 is high, and the user's convenience is also improved.

(4) The upper end fitting portion 21 has a shape that can be fitted into the concave portion 81a of the container 80 which is a beverage can by having the convex portion 21a. Since this top fitting portion 21 is fitted to the container 80 , the stability of the position of the foam generating device 10 with respect to the container 80 can be improved. Moreover, since the vertical position of the fitting part 20 in the upper part of the container 80 is prescribed|regulated by the fitting of the convex part 21a and the recessed part 81a, the ultrasonic generating part 30 It is easy to arrange|position the fitting part 20 containing the container 80 at an appropriate position.

(5) The ultrasonic wave generating unit 30 includes an ultrasonic wave propagating member 32 in contact with the ultrasonic wave generating device 31, and by fitting the container 80 and the fitting part 20 to each other, the ultrasonic wave propagating member ( 32 abuts against the side surface of the vessel 80 so as to be sandwiched between the ultrasonic wave generating device 31 and the side surface of the vessel 80 . Thereby, since the ultrasonic wave emitted by the ultrasonic generator 31 is transmitted to the container 80 through the ultrasonic wave generator 31 and the ultrasonic wave propagating member 32 in close contact with the side surface of the container 80, the transmission efficiency of ultrasonic waves this rises

(6) Viewed from the direction along the axial direction of the ring which the fitting part 20 comprises, the drive part 41, the electric power supply part 42, and the operation part 50 are the center of the ring which the fitting part 20 comprises. It is located on the opposite side to the ultrasonic generator 30 with respect to the. When the user pours the effervescent beverage from the container 80 into the cup 90 , normally, the user holds the container 80 from the side opposite to the spout 83a with respect to the central axis of the container 80 . Therefore, according to the above configuration, since the accommodating part 40 for accommodating the driving part 41 or the power supply part 42 is located in the vicinity of the part where the user's palm touches, the user can use the container together with the accommodating part 40 . (80) can be taken. Therefore, it is easy to hold the container 80 and the foaming device 10, and the stability of the positions of the container 80 and the foaming device 10 when pouring the effervescent beverage from the container 80 into the glass 90 is also rises

In addition, since the operation unit 50 is located in the vicinity of the part held by the user, the user holds the container 80 and the foam generating device 10 while pouring the effervescent beverage from the container 80 into the glass 90 . Also, the operation unit 50 can be easily operated.

(Second Embodiment)

A second embodiment of a foamed beverage foam generating device that is an example of an ultrasonic vibration imparting device will be described with reference to FIGS. 11 to 13 . Below, the difference between 2nd Embodiment and 1st Embodiment is demonstrated mainly, About the structure similar to 1st Embodiment, the same code|symbol is attached|subjected and the description is abbreviate|omitted.

11 , the bubble generating device 11 of the second embodiment differs in the configuration of the accommodating portion from the bubble generating device 10 of the first embodiment. Regarding the configuration other than the accommodating part, the bubble generating device 11 of the second embodiment has the same configuration as the bubble generating device 10 of the first embodiment.

In addition, in FIGS. 11-13, the example comprised so that the outer surface of the ultrasonic wave generating part 30 may have a part which has a step and protrudes from the upper end fitting part 21 is shown. The external shape of the ultrasonic generator 30 is arbitrary, and the shape exemplified in the first embodiment may be employed, or the shape exemplified in the second embodiment may be employed, and a shape different from these may be employed irrespective of the configuration of the housing unit. This may be employed.

12 and 13 , the accommodating part 45 included in the bubble generating device 11 of the second embodiment is disposed above the upper cover part 83 in the container 80 . Specifically, the accommodating portion 45 is a portion of the fitting portion 20 centered on a point located on the opposite side to the ultrasonic generator 30 with respect to the center of the ring constituted by the fitting portion 20 . connected to the top. The accommodating part 45 may be formed integrally with the fitting part 20, and the accommodating part 45 and the fitting part 20 may be connected, after being formed as another member. Viewed from the direction along the axial direction of the fitting portion 20 , the accommodation portion 45 covers almost half of the upper lid portion 83 , and among the regions surrounded by the fitting portion 20 , the accommodation portion 45 . ), the spout 83a is exposed from the region where it is not located.

The housing part 45 accommodates the electric power supply part 42 above the upper lid part 83 . That is, the electric power supply part 42 is arrange|positioned above the container 80 .

The drive part 41 is located on the opposite side to the ultrasonic generator 30 with respect to the center of the ring which the fitting part 20 comprises. The drive part 41 may be accommodated in the accommodating part 45, may be accommodated in the inside of the fitting part 20, and may be accommodated across the accommodating part 45 and the fitting part 20. Alternatively, the accommodating portion for accommodating the driving portion 41 may be formed so as to protrude from the fitting portion 20 to the outer side in the radial direction of the upper end fitting portion 21 .

The operation part 50 is located on the opposite side to the ultrasonic generator 30 with respect to the center of the ring which the fitting part 20 comprises similarly to 1st Embodiment. The operation part 50 is, for example, at a position overlapping the driving part 41 along the radial direction of the upper end fitting part 21 , that is, a region within the outer surface of the fitting part 20 or the receiving part 45 . , or is formed in a region spanning the outer surface of the fitting portion 20 and the outer surface of the accommodating portion 45 .

The foam generating apparatus 11 of the second embodiment is also used in the same manner as the foam generating apparatus 10 of the first embodiment. That is, the user turns off the foam generating device 10, pours an appropriate amount of the effervescent beverage from the container 80 into the glass 90, and then turns on the foam generating device 10 to pour the generated foam into the container ( 80) from the glass (90).

As described above, since the power supply unit 42 accommodates a battery as a power source, the portion of the bubble generating device 11 in which the power supply unit 42 is located tends to be heavier than the other portions. In particular, after the effervescent beverage is poured from the container 80 into the glass 90 , when the container 80 is close to being empty, the vicinity of the electric power supply 42 is the container 80 and the foam generating device 11 . ) is the center of gravity of the structure.

In the configuration in which the power supply 42 is disposed above the container 80, the container 80 and the foam generating device ( It is easy to suppress that the center of gravity of the structure consisting of 11) is biased with respect to the center of the structure. Accordingly, when the container 80 and the foaming device 11 are placed on a horizontal surface, the container 80 and the foaming device 11 are suppressed from falling over. Therefore, handling at the time of use of the foam generating device 11 becomes easy.

As described above, according to the second embodiment, in addition to the effects of (1) to (5) of the first embodiment, the following effects can be obtained.

(7) Since the power supply portion 42 is disposed above the container 80, it is easy to suppress the center of gravity of the structure comprising the container 80 and the foam generating device 11 from being biased with respect to the center of the structure. Accordingly, the container 80 and the foam generating device 11 are less likely to fall over, and handling of the foam generating device 11 in use becomes easy.

In addition, since the operation part 50 is located in the vicinity of the part which a user is holding similarly to 1st Embodiment, a user holds the container 80 and the foam generating device 10, and takes it out of the container 80. The operation part 50 can be easily operated, while pouring a foamed beverage into (90).

(Third embodiment)

A third embodiment of a foamed beverage foaming device that is an example of an ultrasonic vibration imparting device will be described with reference to FIGS. 14 and 15 . Below, the difference between 3rd Embodiment and 1st Embodiment is demonstrated centering around, About the structure similar to 1st Embodiment, the same code|symbol is attached|subjected and the description is abbreviate|omitted.

As FIG. 14 shows, the accommodating part 46 which the bubble generating apparatus 12 of 3rd Embodiment has is extended downward from the fitting part 20. As shown in FIG. When the foam generating device 12 is attached to the container 80 , in the vertical direction, the position of the lower end of the accommodating portion 46 coincides with the position of the lower end of the container 80 . The accommodating part 46 accommodates the drive part 41 and the electric power supply part 42. As shown in FIG.

According to the above configuration, when the container 80 and the foam generating device 12 are stationary on a support such as a table, the lower end of the container 80 and the lower end of the accommodating portion 46 are in contact with the surface of the support. That is, the container 80 and the foam generating device 12 are supported on the support. Accordingly, the container 80 and the foam generating device 12 are less likely to fall over. In particular, the container 80 and the foaming device 12 are even in the case where the container 80 approaches empty so that the center of gravity of the structure comprising the container 80 and the foaming device 12 is biased with respect to the center of the structure. is inhibited from falling. Therefore, handling at the time of use of the foam generating device 12 becomes easy.

Since the power supply part 42 tends to become heavy by accommodating the battery as described above, if the housing part 46 is configured to accommodate the power supply part 42 in the vicinity of its lower end, the container 80 and the foam The position of the generating device 12 is particularly likely to be stable.

The length of the accommodating part 46 in the vertical direction may be formed to a predetermined length matched to the length of the container 80 to be mounted, and the accommodating part 46 is the length of the container 80 to be mounted. In accordance with this, the length in the vertical direction may be configured to be changeable. For example, two types of containers 80 having the same outer diameter and different lengths in the vertical direction, such as a beverage can having a capacity of 350 ml and a beverage can having a capacity of 500 ml, are mounted as a mounting target, and the receiving portion 46 is used. The length of may be changeable in two steps.

Fig. 15 shows an example of the foam generating device 13 in which the length of the accommodating portion 46 can be changed. The accommodating portion 46 has a structure in which an inner portion 47 extending from the fitting portion 20 is inserted inside the outer portion 48 , and the outer portion 48 is vertically disposed along the inner portion 47 . It is configured to slide in the direction.

The inner portion 47 and the outer portion 48 have a locking structure, and with respect to the inner portion 47, the outer portion 48 is engaged at each of the two positions of the first position and the second position. The first position is, for example, a position in which the entire inner portion 47 is inserted into the outer portion 48 . The second position is a position in which a part of the inner portion 47 protrudes from the upper end of the exterior portion 48 and the exterior portion 48 is disposed below compared to the first position. The length of the 2nd position is longer than the 1st position of the accommodating part 46 as a whole. The locking structure is not particularly limited as long as it is a structure in which the outer part 48 is hooked to the inner part 47 . The locking structure is, for example, a structure in which a groove of one of the inner portion 47 and the outer portion 48 catches a protrusion of the other, and a protrusion of each of the inner portion 47 and the outer portion 48 . It is embodied as a structure in which each other is engaged.

The length of the accommodating part 46 when the exterior part 48 is disposed at the first position is the length of the container 80 having the shorter vertical length among the two types of containers 80 to be mounted. When (13) is attached, it is set so that the position of the lower end of the accommodating part 46 and the lower end of the container 80 may correspond.

By sliding the casing portion 48 downward, the position of the casing portion 48 is displaced from the first position to the second position, and the entire length of the receiving portion 46 is extended. The length of the accommodating part 46 when the exterior part 48 is disposed at the second position is the length of the container 80 with the longer length in the vertical direction among the two types of containers 80 to be mounted. When (13) is attached, it is set so that the position of the lower end of the accommodating part 46 and the lower end of the container 80 may correspond.

FIG. 15 shows that, among the two types of containers 80 to be mounted, the container 80 having the longer length in the up-down direction is equipped with a foam generating device 13 in which the exterior part 48 is disposed at the first position. Then, an example in which the exterior part 48 is moved to the second position is shown. Thereby, the position in the vertical direction of the lower end of the accommodating part 46 and the lower end of the container 80 coincides. Moreover, after arranging the exterior part 48 in the 2nd position in advance, you may attach the foam generating device 13 to the container 80. As shown in FIG.

The method of using the foam generating apparatuses 12 and 13 of the third embodiment is the same as that of the foaming apparatus 10 of the first embodiment. 14 and 15 , the operation unit 50 is positioned on the upper surface of the fitting portion 20 on the opposite side to the ultrasonic generator 30 with respect to the center of the ring constituted by the fitting portion 20 . was exemplified. Also in the first embodiment and the second embodiment, the operation part 50 may be located on the upper surface of the fitting part 20 . With this configuration, when the user operates the operation unit 50 with the index finger, the operation unit 50 can be easily operated.

In addition, the structure for making the length of the accommodating part 46 changeable is not limited to the said structure in which the exterior part 48 slides with respect to the inner part 47. As shown in FIG. Moreover, the length of the accommodating part 46 in an up-down direction may be changeable in 3 steps or more.

As described above, according to the third embodiment, in addition to the effects of (1) to (6) of the first embodiment, the following effects can be obtained.

(8) The accommodating part 46 is comprised so that the position of the lower end of the accommodating part 46 in an up-down direction and the position of the lower end of the container 80 may correspond. As a result, when the container 80 to which the foam generating device 12, 13 is mounted is left still on the support, since the container 80 and the foam producing device 12, 13 are supported by the support, the container 80 and The foam generating device 12 , 13 becomes difficult to topple over. Moreover, by aligning the position of the lower end of the accommodating part 46 and the container 80, the position alignment of the bubble generating apparatus 12, 13 with respect to the container 80 is also possible easily.

(9) Since the length of the accommodating part 46 in the up-down direction is configured to be changeable, a plurality of types of containers 80 having different lengths in the up-down direction are used as mounting targets of the foam generating device 13 . can do. Accordingly, the versatility of the foam generating device 13 is increased.

(variant example)

It is possible to change and implement each said embodiment as follows.

[Location of the control unit 50]

A modified example of the configuration of the position of the operation unit 50 and the periphery of the operation unit 50 will be described.

In the first embodiment, the form in which the user operates the operation unit 50 by holding the container 80 together with the foam generating device 10 so that the palm touches the receiving unit 40 has been exemplified. Without being limited to this, the user may hold the foam generating device and the container so that the back of the finger touches the receiving portion. Moreover, the structure for guide|inducing the method of holding the bubble generating apparatus and a container by a user may be formed in the accommodating part.

For example, like the bubble generating apparatus 14 shown in FIG. 16 , the accommodating part 49 may have the recessed part 51 around the operation part 50 . The operation part 50 is located at the bottom of the recessed part 51 . In this case, as FIG. 17 shows, a user holds the foam generating apparatus 14 and the container 80 so that the forefinger may align with the recessed part 51 and the operation part 50 may be operated. That is, the method of holding the foam generating device 14 and the container 80 so that the back of the finger touches the receiving portion 49 is induced. In this gripping method, compared to a gripping method in which the palm touches the receiving portion, even a user with a small hand can easily grip the foam generating device 14 and the container 80 . In addition, since it is not necessary to move the forefinger significantly during operation of the operation unit 50 , it is easy to operate the operation unit 50 while holding the foam generating device 14 and the container 80 . Further, when pouring the effervescent beverage, the user can tilt the foaming device 14 and the container 80 while supporting the lower side of the container 80 with the thumb, so that the foaming device 14 and the container ( 80) is easy to stabilize the angle of.

Like the bubble generating device 15 shown in FIG. 18 , the operation unit 50 may be disposed above the upper cover unit 83 in the container 80 . In detail, the support part 52 which supports the operation part 50 is arrange|positioned above the upper cover part 83, and the operation part 50 is located in the upper surface of the support part 52. As shown in FIG. The support part 52 is connected with the upper end of the part centering on the point located on the opposite side to the ultrasonic generator 30 with respect to the center of the ring which the fitting part 20 comprises of the fitting part 20. . Viewed from the direction along the axial direction of the fitting portion 20 , the spout 83a is exposed from the region where the support portion 52 is not located among the areas surrounded by the fitting portion 20 .

19 , the user holds the foam generating device 15 and the upper part of the container 80 from the side opposite to the ultrasonic generator 30 with respect to the container 80 . At this time, since the operation part 50 is arrange|positioned above the upper cover part 83, when a forefinger is naturally spread out, it is easy for a finger to touch the operation part 50. As shown in FIG. Accordingly, it is easy to operate the operation unit 50 while holding the foam generating device 15 and the container 80 .

Like the foam generating device 16 shown in FIG. 20 , the operation part 50 may be disposed on the upper surface of the fitting part 20 on the side of the spout 83a. In other words, the operation part 50 is located in the upper surface of the part which connects the ultrasonic generator 30 and the accommodation part 40 among the fitting parts 20.

As FIG. 21 shows, the user holds the bubble generating device 16 and the container 80 from the side opposite to the ultrasonic generator 30 with respect to the container 80. At this time, since the operation part 50 is arrange|positioned at the side of the spout 83a, when a forefinger is spread|opened, a finger touches the operation part 50 easily. Therefore, it is easy to operate the operation part 50 while holding the foam generating device 16 and the container 80 .

What is necessary is just to determine which side the operation part 50 is arrange|positioned with respect to the spout 83a on the right side and the left side according to which user among a right-handed person and a left-handed person is targeted. Or, the operation part 50 may be arrange|positioned at two points on the right side and the left side with respect to the spout 83a.

In addition, in FIG. 16 and FIG. 17, the form in which the bubble generating apparatus 14 is equipped with the display part 60 was illustrated. The display unit 60 indicates whether the bubble generating device is on or off, ie, the presence or absence of driving of the ultrasonic wave generating device 31 . The display unit 60 includes, for example, a light source such as an LED, and notifies the driving state of the ultrasonic wave generator 31 to the outside by lighting of the light source. According to such a structure, a user can grasp|ascertain the driving state of the ultrasonic generator 31 easily. The bubble generating apparatus of each of the above embodiments and modifications may also include the display unit 60 .

Although the position of the display part 60 is not specifically limited, For example, as shown in FIGS. 16 and 17, when viewed from the direction along the axial direction of the ring which the fitting part 20 comprises, the ultrasonic wave with respect to the center of the said ring. A display unit 60 is disposed on the opposite side to the generating unit 30 . By disposing the display unit 60 at such a position, the user can easily see the display unit 60 even while the user holds the foam generating device 14 and the container 80 and pours the effervescent beverage into the glass 90 .

[Protection of the ultrasonic generator 31]

As described in the first embodiment, if the ultrasonic generator 30 is configured to be separated from the upper end of the container 80, the effervescent beverage flowing out from the spout 83a is unlikely to adhere to the foam generating device. However, if the foamed beverage is attached to the ultrasonic generator 30, it is preferable that the ultrasonic generator 31, which is an electronic component, is protected from intrusion of the attached foamed beverage or liquid such as moisture used for cleaning it. do. The structure for protection of this ultrasonic generator 31 is demonstrated.

The foam generating apparatus 17 shown in FIG. 22 is equipped with the protective sheet 70 which covers the ultrasonic generator 31 from the inside of the fitting part 20. As shown in FIG. The protective sheet 70 has covered the ultrasonic generator 31 and the part which surrounds the outer periphery of the ultrasonic generator 31 among the inner surface 20S of the fitting part 20. As the protective sheet 70 , a sheet made of a material that does not easily impede the transmission of ultrasonic waves and does not allow liquids to pass therethrough is used. For example, as the protective sheet 70, a sheet made of a resin such as polyethylene terephthalate is used. In addition, the part to which the protective sheet 70 is pasted among the inner side surface 20S of the fitting part 20 comprises the inner side surface of the ultrasonic generator 30 .

23 , the bubble generating device 17 does not include the ultrasonic wave propagating member 32 , and the ultrasonic wave generating device 31 has an opening ( It is arranged so that the front end surface of the ultrasonic generator 31 protrudes from 20a). In detail, the ultrasonic generator 30 is equipped with the elastic member 33 which is a spring, for example. The base end of the ultrasonic generator 31 is connected to the elastic member 33, and the protrusion amount of the ultrasonic generator 31 from the opening part 20a changes with the expansion/contraction of the elastic member 33. Moreover, the wiring (not shown) which connects the ultrasonic generator 31 and the drive part 41 is passed through the inside of the fitting part 20. As shown in FIG.

The protective sheet 70 is affixed to the inner surface 20S of the fitting portion 20 via an adhesive layer 71 . It is preferable that the adhesive layer 71 is disposed only between the inner surface 20S of the fitting portion 20 and the protective sheet 70 , and is not disposed between the ultrasonic wave generator 31 and the protective sheet 70 . do. That is, it is preferable that the ultrasonic generator 31 and the protective sheet 70 are in direct contact. According to such a structure, since attenuation of an ultrasonic wave is suppressed by passing through the adhesion layer 71, the transmission efficiency of the ultrasonic wave from the ultrasonic generator 31 to the container 80 becomes high. In addition, it is preferable that the protective sheet 70 has flexibility and expands and contracts according to the change in the amount of protrusion of the ultrasonic generator 31 following the tip surface of the ultrasonic generator 31 . When the foam generating device 17 is not mounted on the container 80 , the protrusion amount of the ultrasonic generator 31 is maximum, and the front end surface of the ultrasonic generator 31 abuts against the protective sheet 70 . .

24 , when the foam generating device 17 is attached to the container 80 , the protective sheet 70 , the ultrasonic generator 31 , and the elastic member 33 are formed of the container 80 . pressed from the side. At this time, the ultrasonic generator 31 receives the restoring force of the elastic member 33 and is pressed against the side surface of the container 80 together with the protective sheet 70 .

When the elastic member 33 is not formed, if the ultrasonic wave generating device 31 protrudes excessively from the opening 20a, it fits into the container 80, especially when the elasticity of the fitting portion 20 is small. It is difficult to mount the part 20 . On the other hand, if the ultrasonic wave generating device 31 does not protrude from the opening 20a, a gap is formed between the side surface of the container 80 and the ultrasonic wave generating device 31 after the fitting portion 20 is mounted, so that the ultrasonic wave difficult to convey On the other hand, in the bubble generating device 17, when the fitting portion 20 is attached, the amount of protrusion of the ultrasonic generating device 31 is finely adjusted by the deformation of the elastic member 33, so that the ultrasonic generating device ( The formation of a gap between the side surface of the container 80 and the ultrasonic wave generating device 31 is suppressed while suppressing that the projection of the 31 ) becomes an obstacle to the mounting of the fitting portion 20 . Therefore, the transmission efficiency of the ultrasonic wave from the ultrasonic generator 31 to the container 80 becomes high.

And in the bubble generating device 17, since the protective sheet 70 covers the ultrasonic generator 31 and its periphery from the inside of the fitting part 20, liquid in the vicinity of the ultrasonic generator 31. intrusion is inhibited. In order to smoothly change the amount of protrusion of the ultrasonic generator 31 , it is preferable that a minute gap is formed between the opening 20a and the ultrasonic generator 31 . Even when such a gap is formed, when the protective sheet 70 covers the ultrasonic wave generator 31 and its periphery from the inside of the fitting portion 20 , the liquid enters the vicinity of the ultrasonic wave generator 31 . is properly restrained.

In addition, the bubble generating device 17 is not provided with the elastic member 33, and the position of the ultrasonic wave generating device 31 may be fixed. Further, as in each of the above embodiments, a form in which the amount of protrusion of the ultrasonic wave generator 31 from the opening 20a can be changed by the elastic member 33 may be applied to the form not provided with the protective sheet 70 . .

Another example of the structure for protecting the ultrasonic wave generating device 31 from intrusion of a liquid will be described.

In the bubble generating device 18 shown in FIG. 25 , the opening 20a is not formed in the inner surface 20S of the fitting portion 20 , and the ultrasonic generator 31 is always connected to the fitting portion 20 . is housed inside of In other words, the ultrasonic wave generating device 31 is accommodated inside the case of the bubble generating device 18 . And, the ultrasonic generator 30 includes an elastic member 33 which is, for example, a spring, and an inner protrusion 34 protruding from the side wall 20W of the fitting portion 20 to the inside of the fitting portion 20 . and an external projection 35 protruding from the side wall 20W of the fitting portion 20 to the outside of the fitting portion 20 . The outer projection 35 protrudes from the inner surface 20S. Further, a portion of the sidewall 20W of the fitting portion 20 in which the inner projection 34 and the outer projection 35 are located constitutes the sidewall of the ultrasonic generator 30 .

The tip of the ultrasonic generator 31 is in contact with the inner projection 34 , and the base end of the ultrasonic generator 31 is connected to the elastic member 33 . The ultrasonic generator 31 is pressed against the inner protrusion 34 by the restoring force of the elastic member 33 . The elastic member 33 in the present modification finely adjusts the position of the ultrasonic wave generating device 31 inside the fitting portion 20 so that the ultrasonic wave generating device 31 abuts against the inner protrusion 34 . formed to do If fine adjustment of the position of the ultrasonic generator 31 is unnecessary, the elastic member 33 may not be provided.

In order to increase the transmission efficiency of ultrasonic waves, it is preferable that the inner protrusion 34 has a cylindrical shape having a diameter smaller than that of the front end surface of the ultrasonic generator 31 . In the front end surface of the ultrasonic generator 31, the closer to the center, the stronger the ultrasonic wave is emitted, so that the inner protrusion 34 is in contact with the central portion of the front end surface of the ultrasonic generator 31, so that the ultrasonic transmission efficiency can increase

The outer protrusion 35 is formed at a position overlapping the inner protrusion 34 with the side wall 20W of the fitting portion 20 interposed therebetween. In order to increase the transmission efficiency of ultrasonic waves, it is preferable that the outer protrusion 35 has a hemispherical shape having a bottom surface in the inner surface of the fitting portion 20 . Since the side surface of the container 80 is a curved surface, rather than a form in which the tip of the external projection 35 is flat, the tip of the external projection 35 is a curved surface, and the side surfaces of the external projection 35 and the container 80 are at this point. The contact form can raise the transmission efficiency of an ultrasonic wave. Moreover, if the outer protrusion 35 is hemispherical, when the outer protrusion 35 comes into contact with the side surface of the container 80, it is suppressed that the side surface of the container 80 is damaged by the tip of the outer protrusion 35 do.
