Description

This disclosure relates to a beverage server and a dispensing member.

Various types of beverage servers and dispensing members for dispensing beverages such as beer have been known in the past. JP 2018-127280 A describes a beverage server and dispensing member. The beverage server is equipped with a faucet equipped with a lever, and beer liquid or foam is dispensed by operating the lever. The faucet is equipped with a liquid nozzle for dispensing beer liquid and a foam nozzle for dispensing foam.

The pouring member has a cylindrical fitting protrusion that is attached to the foam nozzle of the faucet, and a cylindrical flow path conversion portion that is expanded in diameter at the bottom of the fitting protrusion. A flow path through which the beer foam flows is formed inside the fitting protrusion and the flow path conversion portion. This flow path has a first extension portion that extends downward from the upper end of the fitting protrusion, a bent portion that is bent at the lower end of the first extension portion, and a second extension portion that extends approximately horizontally from the bent portion. An outlet through which the beer foam flows out to the outside of the pouring member is formed at the tip of the second extension portion.

The aforementioned pouring member has a bent portion at the lower end of the first extending portion, so that the flow path through which the beer foam passes is bent so as to follow the liquid surface of the beer liquid in the beverage container. The tip of the flow path is bent so as to form an angle of 0° or more and 45° or less above and below the liquid surface of the beer liquid. In other words, the flow path is formed so that the pouring angle of the beer foam is an angle of 0° or more and 45° or less above and below the horizontal direction.

In the above-mentioned pouring member, the second extension part of the flow path is bent by a bend formed inside the pouring member, so that the beer foam in the foaming nozzle is poured out from the outlet so as to follow the liquid surface of the beer liquid. By pouring the beer foam out so as to follow the liquid surface in this way, it is made difficult for the beer foam to mix with the beer liquid.

JP 2018-127280 A

In the above-mentioned pouring member, the flow path is provided with a second extending portion that extends from the bent portion in a substantially horizontal direction, so that the foam is poured in a substantially horizontal direction. Therefore, when the foam is poured, the foam may fly out in a substantially horizontal direction, and may fly out of the beverage container. If the foam is poured out with force and the foam jumps out a long distance, there is a possibility that the foam may fly out of the beverage container.

As a result, it may be difficult to determine the position of the beverage container so that the foam does not fly out of the beverage container, and skill may be required to pour the foam. In addition, in order to prevent the foam from flying out of the beverage container, the bottom end of the pouring member must be brought close to the liquid surface when pouring the foam, which means that the foam is likely to adhere to the liquid nozzle or the bottom end of the pouring member.

If foam adheres to the bottom end of the liquid nozzle or the dispensing member, it not only looks bad, but it can also be a problem from a hygiene standpoint. Furthermore, if the foam shoots out in a roughly horizontal direction, it may collide with the inner surface of the beverage container, which can result in the foam easily sinking into the liquid surface. Therefore, it is necessary to suppress the momentum of the foam being dispensed in a roughly horizontal direction.

The present disclosure aims to provide a beverage server and dispensing member that can suppress the momentum of foam dispensed in a substantially horizontal direction, facilitate the foam dispensing operation, and prevent foam adhesion.

The beverage server of the present disclosure comprises a faucet having a foam nozzle through which the foam of the beverage passes to be poured onto the liquid, and a pouring member attached to the foam nozzle and pouring the foam that has passed through the foam nozzle onto the liquid, the pouring member having a foam flow path through which the foam passes, and a foam outlet from which the foam that has passed through the foam flow path flows out, the foam outlet opening in a direction along the liquid surface of the liquid, and the area of the foam outlet being 45 ^mm2 or more and 75 ^mm2 or less.

In this beverage server, the pouring member attached to the foam nozzle of the faucet includes a foam flow path and a foam outlet. The foam from the foam nozzle passes through the foam flow path, and the foam outlet is open in a direction along the liquid surface. Therefore, the foam that passes through the foam flow path of the pouring member is poured from the foam outlet in a substantially horizontal direction. In this beverage server, the area of the foam outlet is set to 45 ^mm2 or more. By setting the area of the foam outlet to ⁴⁵ mm2 or more, the area of the foam outlet can be increased to suppress the momentum of the foam, thereby reducing the possibility of the foam popping out of the beverage container. Therefore, even if the lever is normally operated, the foam does not pop out of the beverage container, so that even an unskilled person can easily perform the foam pouring operation. Furthermore, by suppressing the momentum of the foam pouring, the foam can be suppressed from popping out of the beverage container even if the lower end of the pouring member is not brought close to the liquid surface, so that the adhesion of the foam to the liquid nozzle or the lower end of the pouring member can be suppressed. In addition, by suppressing the momentum of the poured foam, it is possible to mitigate the impact of the foam on the inner surface of the beverage container, thereby suppressing the foam from sinking under the liquid surface. Furthermore, by setting the area of the foam outlet to ⁷⁵ mm2 or less, it is possible to appropriately maintain the momentum of the poured foam, thereby more reliably suppressing the foam from sinking under the liquid surface.

The faucet may also have a liquid nozzle through which the beverage passes, the liquid nozzle having a liquid flow path through which the liquid passes and a liquid outlet from which the liquid that has passed through the liquid flow path flows out, and the distance between the foam outlet and the liquid outlet may be 2 cm or less. However, if the distance between the liquid outlet and the foam outlet is too long, it may happen that the beverage container must be moved to pour the foam after the liquid has been poured into the beverage container. In contrast, as described above, if the distance between the foam outlet and the liquid outlet is 2 cm or less, the foam outlet and the liquid outlet can be brought closer to each other. Therefore, the foam can be poured without moving the beverage container after the liquid has been poured into the beverage container, and since it is not necessary to move the beverage container, the beverage pouring operation can be performed efficiently.

The faucet may also be equipped with a liquid nozzle through which the beverage passes, and the sum of the length of the foam nozzle and the length of the dispensing member may be longer than the length of the liquid nozzle. In this case, by making the sum of the length of the foam nozzle and the length of the dispensing member longer than the length of the liquid nozzle, the liquid nozzle can be moved farther away from the liquid surface when dispensing the foam. This makes it possible to more reliably prevent the foam from adhering to the liquid nozzle.

The pouring member may be tubular and extend from the foam nozzle toward the liquid surface, and the length of the foam outlet in the width direction of the pouring member may be equal to or greater than the length of the foam outlet in the longitudinal direction of the pouring member. In this case, by making the horizontal length of the foam outlet equal to or greater than the vertical length, the poured foam can be prevented from extending vertically, and the foam can be more reliably prevented from popping out of the beverage container.

The beverage server may also be provided with an air flow path that communicates with the foam flow path. In this case, by providing an air flow path that communicates with the foam flow path through which the foam passes, the foam remaining in the foam flow path can be quickly discharged by the air passing through the air flow path. Therefore, when the foam is stopped being poured, the foam is quickly discharged from the foam outlet, which can suppress dripping, which is the foam continuing to drip for a long period of time.

The air flow path may also be a groove extending upward relative to the foam flow path. In this case, since the air flow path is a groove extending upward relative to the foam flow path, leakage of foam from the foam flow path through the air flow path can be suppressed.

The pouring member of the present disclosure is a pouring member that is attached to a foam nozzle of a faucet through which the foam of a beverage passes to be poured onto a liquid, and has a foam flow path through which the foam that has passed through the foam nozzle passes, and a foam outlet from which the foam that has passed through the foam flow path flows out, the foam outlet opening in a direction along the liquid surface of the liquid, and the area of the foam outlet being ⁴⁵ mm2 or more and ⁷⁵ mm2 or less.

This pouring member includes a foam flow path and a foam outlet, and the foam outlet is open in a direction along the liquid surface. Therefore, the foam is poured from the foam outlet in a substantially horizontal direction. In this pouring member, the area of the foam outlet is set to 45 ^mm2 or more, so that the momentum of the foam can be suppressed by increasing the area of the foam outlet. Therefore, as with the beverage server described above, the possibility of the foam jumping out of the beverage container can be reduced. Therefore, even if one is not skilled, the foam can be easily poured out, and the foam can be prevented from jumping out of the beverage container even if the lower end of the pouring member is not brought close to the liquid surface. As a result, the adhesion of the foam to the liquid nozzle or the lower end of the pouring member can be suppressed. In addition, the momentum of the poured foam can be suppressed to mitigate the impact of the foam on the inner surface of the beverage container, so that the foam can be prevented from sinking into the liquid surface. Furthermore, since the area of the foam outlet is set to 75 ^mm2 or less, the momentum of the poured foam can be appropriately maintained, so that the foam can be more reliably prevented from sinking into the liquid surface.

The dispensing member may also have an air flow path that communicates with the foam flow path. In this case, as with the beverage server described above, the remaining foam can be quickly expelled by air passing through the air flow path, thereby preventing the foam from dripping. Furthermore, by providing the dispensing member with this air flow path, there is no need to form an air flow path in the faucet, making it possible to use an existing faucet.

According to the present disclosure, the force of the foam being poured in a substantially horizontal direction can be suppressed, making it easier to pour the foam and preventing the foam from adhering.

Below, an embodiment of a beverage server and a dispensing member according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are given the same reference numerals, and duplicated descriptions will be omitted as appropriate. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios and angles, etc. are not limited to those shown in the drawings.

First Embodiment
Fig. 1 is a perspective view showing the exterior of a beverage server 1 according to a first embodiment. Fig. 2 is a perspective view showing an example of a state in which a beverage is dispensed from a faucet 10 of the beverage server 1. The beverage server 1 is a device installed in, for example, a restaurant, and is capable of dispensing a beverage by operating a lever 11 in response to a customer's order, etc.

The beverage is, for example, a sparkling beverage D. The sparkling beverage D contains, for example, a fermented alcoholic drink containing a gas such as carbon dioxide gas, and has a foaming characteristic in which a layer of foam B is formed on the liquid L when poured into a beverage container C, and in which the formed foam B is maintained for a certain period of time or more.

Sparkling beverage D is, for example, a beverage that has a NIBEM value of 50 seconds or more according to the EBC (European Brewery Convention) method. The NIBEM value is an index value that indicates the foam retention characteristics of a beverage. Sparkling beverage D may be a beer-flavored beverage. Beer-flavored beverages include beverages that taste like beer and beverages that give the drinker the sensation of drinking beer. Beer-flavored beverages with an alcohol content of 1% or more are also called beer-flavored alcoholic beverages.

Furthermore, beer-taste beverages include malt fermented beverages that use malt as an ingredient, such as beer, happoshu, non-alcoholic beer, and liqueurs (e.g., beverages classified as "liqueur (sparkling) (1)" under the Liquor Tax Act), as well as beer-taste beverages that do not use barley or malt as an ingredient (e.g., beverages classified as "other brewed alcoholic beverages (sparkling) (1)" under the Liquor Tax Act). Note that sparkling beverage D may be a beverage other than a beer-taste beverage. Below, an example will be described in which liquid L is a beer liquid and sparkling beverage D is beer.

For example, the beverage server 1 is equipped with multiple (for example, two) faucets 10, and the beverage server 1 is capable of serving multiple types of beverages (for example, two types). The faucets 10 are attached to the housing 2 of the beverage server 1. For example, a beverage hose is connected to the beverage server 1, and beverages are supplied from the beverage hose to the inside of the beverage server 1. The beverage server 1 cools the supplied beverage. As an example, the beverage server 1 is an electric instant-cooling server.

Figure 3 is a side view showing the faucet 10. As shown in Figures 2 and 3, for example, the faucet 10 includes a lever 11 that can be gripped by hand to move it, a faucet body 12 to which the lever 11 is attached and which is fixed to the housing 2, a liquid nozzle 13 that extends diagonally downward from the faucet body 12, and a foam nozzle 14 that is located on the opposite side of the housing 2 from the liquid nozzle 13. Note that Figure 3 shows a simplified internal structure of the faucet body 12.

The lever 11 can be moved, for example, to both the opposite side of the housing 2 and to the housing 2 side (the rear side, for example the left side of the paper in Figures 2 and 3) when the user is positioned on the opposite side of the housing 2 as viewed from the faucet 10 (the front side of the beverage server 1, for example the right side of the paper in Figures 2 and 3). In what follows, the opposite side of the housing 2 as viewed from the faucet 10 may simply be referred to as the front side, and the housing 2 side may simply be referred to as the rear side. The lever 11 is, for example, cylindrical, and extends upward from the faucet body 12. As an example, the lever 11 is shaped so that its diameter gradually increases as it moves upward.

The faucet body 12 includes, for example, a cylindrical portion 12b in which the lever 11, the liquid nozzle 13, and the foam nozzle 14 are provided, and an attachment portion 12c that expands in diameter on the side of the cylindrical portion 12b opposite the lever 11. As an example, the attachment portion 12c is attached to a protruding portion 2b that protrudes toward the front of the housing 2.

For example, the attachment portion 12c is rotatable relative to the cylindrical portion 12b. As an example, the attachment portion 12c can be attached to the housing 2 by rotating in one direction (e.g., clockwise) relative to the cylindrical portion 12b, and can be removed from the housing 2 by rotating in the opposite direction (e.g., counterclockwise) relative to the cylindrical portion 12b.

A slide valve 12d is provided inside the faucet body 12 to open and close the flow path of liquid L located inside the faucet body 12. For example, when the lever 11 moves to the front, the slide valve 12d moves to the back and liquid L is poured from the liquid nozzle 13, and when the lever 11 moves to the back, the slide valve 12d moves to the front and foam B flows into the foam nozzle 14.

The liquid nozzle 13 is, for example, cylindrical, and inclines toward the front (foam nozzle 14 side) as it moves away from the faucet body 12. As an example, the liquid nozzle 13 may be cylindrical and taper toward the tip. However, the shape of the liquid nozzle 13 is not limited to the above example and can be modified as appropriate.

The liquid nozzle 13 has a liquid flow path 13b through which the liquid L passes, and a liquid outlet 13c through which the liquid L flows out after passing through the liquid flow path 13b. The liquid flow path 13b is formed inside the liquid nozzle 13, and the liquid outlet 13c opens at the lower end of the liquid nozzle 13. The liquid flow path 13b is connected to a flow path 12f through which the liquid L passes inside the faucet body 12.

The liquid outlet 13c opens, for example, at the lower end of the liquid flow path 13b, and the liquid L is poured from the liquid outlet 13c to the outside of the faucet 10. The foam nozzle 14 extends downward from the faucet body 12 in front of the liquid nozzle 13, and the foam B flows into the foam nozzle 14 via the slide valve 12d.

The beverage server 1 is equipped with a dispensing member 20 that dispenses foam B that has passed through the foam nozzle 14. The dispensing member 20 is attached to the foam nozzle 14 and dispenses the foam B that has passed through the foam nozzle 14 onto the liquid L. The dispensing member 20 has a hollow structure that has a foam flow path 21 inside through which the foam B passes.

For example, the dispensing member 20 is in the form of a cylinder with a bottom. As an example, the dispensing member 20 may be in the form of a cylinder with a bottom, and may taper toward the tip 20b of the dispensing member 20 (as it moves away from the foam nozzle 14). In this case, the outer circumferential surface 20c of the dispensing member 20 has a smaller diameter toward the tip 20b. However, the shape of the dispensing member 20 is not limited to the above example and can be changed as appropriate. As an example, the inner diameter of the dispensing member 20 may be the same as the diameter of the foam outlet 22 described below.

The sum of the length N1 of the foam nozzle 14 and the length N2 of the dispensing member 20 is, for example, longer than the length N3 of the liquid nozzle 13. The length N1 of the foam nozzle 14 indicates the length of the exposed portion of the foam nozzle 14, and may indicate the length from the base of the foam nozzle 14 to the junction with the dispensing member 20. For example, the length N2 indicates the distance from the base end 20f to the tip 20b of the dispensing member 20, and the length N3 indicates the length from the base of the liquid nozzle 13 to the faucet body 12 to the liquid outlet 13c.

The value of the sum of length N1 and length N2 is, for example, 1.5 times or less than the value of length N3. The value of the sum of length N1 and length N2 may also be 1.4 times or less, 1.3 times or less, 1.2 times or less, or 1.1 times or less than the value of length N3. The value of the sum of length N1 and length N2 may be the same as the value of length N3, or may be smaller than the value of length N3.

The inner diameter of the dispensing member 20 may be equal to or larger than the outer diameter of the foam nozzle 14. The dispensing member 20 may be attached to the foam nozzle 14 by fitting such that the inner peripheral surface of the dispensing member 20 abuts against the outer peripheral surface of the foam nozzle 14. When the dispensing member 20 is attached to the foam nozzle 14 by fitting, the configuration of the dispensing member 20 can be simplified, and the dispensing member 20 can be easily attached by pushing the dispensing member 20 into the foam nozzle 14. Note that the dispensing member 20 may be attached to the foam nozzle 14 by a means other than fitting, such as screwing. The dispensing member 20 may be fixed to the foam nozzle 14, or may be detachable from the foam nozzle 14.

The pouring member 20 has a foam flow path 21 through which the foam B passes, and a foam outlet 22 from which the foam B flows out after passing through the foam flow path 21. As shown in Figures 3 and 4, the foam outlet 22 opens in a direction along the liquid level L1 of the liquid L. Therefore, the foam B is poured out from the foam outlet 22 in a substantially horizontal direction.

The foam outlet 22 may be formed, for example, so that the pouring angle of the foam B (the angle of the foam B with respect to the liquid L immediately after being poured from the foam outlet 22) is an angle of 0° or more and 45° or less above and below the liquid L. The foam outlet 22 is oriented, for example, in a direction of 0° or more and 45° or less above and below the liquid level L1 of the liquid L.

The angle at which the foam outlet 22 is directed is preferably 0° or more and 30° or less above the liquid level L1, or 0° or more and 30° or less below the liquid level L1, and may further be 0° or more and 15° or less above the liquid level L1, or 0° or more and 15° or less below the liquid level L1. The direction along the liquid level L1 and the horizontal direction may be the same direction.

Figure 5(a) is an enlarged side view of the liquid nozzle 13 and the dispensing member 20. As shown in Figure 5(a), the liquid nozzle 13 and the dispensing member 20 extend, for example, at an angle so that they approach each other toward the tip. In other words, the liquid outlet 13c of the liquid nozzle 13 and the tip 20b of the dispensing member 20 are close to each other.

The liquid outlet 13c located at the lower end of the liquid nozzle 13 is provided, for example, vertically above the tip 20b of the pouring member 20 (at a location farther from the liquid level L1). For example, the distance K between the liquid outlet 13c of the liquid nozzle 13 and the foam outlet 22 of the pouring member 20 is 2 cm or less. As an example, the distance K indicates the center-to-center distance between the center of the liquid outlet 13c and the center of the foam outlet 22. The lower limit of the distance K is, for example, 0.5 cm, and may be 1 cm or 1.5 cm. The upper limit of the distance K may be 3 cm or 2.5 cm.

The height difference H between the liquid outlet 13c and the foam outlet 22 is, for example, 2 cm or less, and may be 1.5 cm or less, 1 cm or less, 0.5 cm or less, 0 cm or less, or -1 cm. If the height difference H exceeds 2 cm, the pouring member 20 may come into contact with the liquid level L1. The distance W between the liquid outlet 13c and the tip 20b in the longitudinal direction of the faucet body 12 (the direction in which the liquid nozzle 13 and the pouring member 20 are aligned) is, like the difference H, for example, 2 cm or less, and may be 1.5 cm or less, 1 cm or less, or 0.5 cm or less. Furthermore, the liquid nozzle 13 and the pouring member 20 may be integrated.

For example, the width A of the foam outlet 22 may be greater than 7.0 mm, and may be 7.1 mm or more, 7.5 mm or more, or 8.0 mm or more. The upper limit of the width A may be, for example, less than 10 mm, and may be 9.5 mm, 9 mm, or 8.5 mm. As an example, the foam outlet 22 is circular, and in this case, the width A corresponds to the diameter of the foam outlet 22.

As shown in Figures 5(b), 5(c) and 5(d), the shape of the foam outlet of the pouring member 20 can be changed as appropriate. For example, the pouring member 20 may have a square foam outlet 22b instead of the foam outlet 22, in which case the width A corresponds to the length of one side of the foam outlet 22.

Instead of the foam outlet 22, the dispensing member 20 may have a rectangular foam outlet 22c. For example, the length Y1 of the foam outlets 22, 22b, 22c in the width direction X1 of the dispensing member 20 is equal to or greater than the length Y2 of the foam outlets 22, 22b, 22c in the length direction X2 of the dispensing member 20. The dispensing member 20 may have a foam outlet 22d whose length Y1 in the width direction X1 is shorter than the length Y2 in the length direction X2.

The area of the foam outlet 22 is, for example, 45 mm ² or more and 75 mm ² or less. The lower limit of the area of the foam outlet 22 may be 50 mm ² , 55 mm ² , or 60 mm ^2. The upper limit of the area of the foam outlet 22 may be 70 mm ² , 65 mm ² , or 60 mm ^2. As an example, the area of the foam outlet 22 may be 48 mm ² or more and 58 mm ² or less.

Next, the angle of the foam B when viewed from above will be described with reference to Figures 6, 7(a) and 7(b). As shown in Figure 6, the angle of the foam B with respect to the reference line Z passing through the faucet body 12 and the housing 2 is, for example, greater than 0° and less than 180°.

Specifically, when foam B is poured to the right of the reference line Z in a plan view, the pouring angle θ1 of foam B with respect to the reference line Z may be 70° or more and 110° or less, 85° or more and 95° or less, 110° or more and 150° or less, or 125° or more and 135° or less. The pouring angle θ1 may also be 90°.

When foam B is poured to the left of reference line Z in plan view, the pouring angle θ2 of foam B with respect to reference line Z may be 70° or more and 110° or less, 85° or more and 95° or less, 110° or more and 150° or less, or 125° or more and 135° or less, or may be 90°, similar to pouring angle θ1. When pouring angle θ1 and pouring angle θ2 are within the above angle ranges, foam B can be poured along the inner surface C1 of beverage container C, thereby preventing foam B from sinking into liquid surface L1 and preventing foam B from hitting liquid surface L1.

As shown in Figures 7(a) and 7(b), foam B may be poured out to the left or right of beverage container C. Foam B may be poured out at an angle to reference line Z, for example. In this case, the impact of foam B against the inner surface C1 of beverage container C can be mitigated, thereby preventing foam B from hitting liquid L and from sinking into liquid L.

As an example, when the beverage container C is held in the right hand, the foam B is preferably poured out to the left, and when the beverage container C is held in the left hand, the foam B is preferably poured out to the right. As yet another example, when the pouring member 20 is located on the rear side of the beverage container C (the side facing the housing 2), the pouring angles θ1, θ2 are preferably greater than 90° and less than 180°, and when the pouring member 20 is located on the front side of the beverage container C (the side opposite the housing 2), the pouring angles θ1, θ2 are preferably greater than 0° and less than 90°.

Next, the effects of the beverage server 1 and the dispensing member 20 according to this embodiment will be described in detail. As shown in Figures 4 and 5, in the beverage server 1 and the dispensing member 20, the dispensing member 20 attached to the foam nozzle 14 of the faucet 10 has a foam flow path 21 and a foam outlet 22. Foam B from the foam nozzle 14 passes through the foam flow path 21, and the foam outlet 22 opens in a direction along the liquid level L1 of the liquid L. Therefore, foam B that has passed through the foam flow path 21 of the dispensing member 20 is dispensed from the foam outlet 22 in an approximately horizontal direction.

In the beverage server 1, the area of the foam outlet 22 is set to 45 ^mm2 or more. By setting the area of the foam outlet 22 to ⁴⁵ mm2 or more, the area of the foam outlet 22 can be increased to suppress the momentum of the foam B, thereby reducing the possibility of the foam B flying out of the beverage container C.

As a result, even when the lever 11 is operated normally, the foam B does not pop out of the beverage container C, so even those without experience can easily pour the foam B. Furthermore, by suppressing the force of the foam B being poured out, the foam B can be prevented from popping out of the beverage container C even if the tip 20b, which is the lower end of the pouring member 20, is not brought close to the liquid surface L1, so that adhesion of the foam B to the liquid nozzle 13 or the lower end of the pouring member 20 can be suppressed.

By suppressing the momentum of the poured out foam B, it is possible to mitigate the collision of the foam B with the inner surface C1 of the beverage container C, thereby suppressing the foam B from sinking into the liquid surface L1. Furthermore, by setting the area of the foam outlet 22 to ⁷⁵ mm2 or less, it is possible to appropriately maintain the momentum of the poured out foam B, thereby more reliably suppressing the foam B from sinking into the liquid surface L1.

The faucet 10 also includes a liquid nozzle 13 through which the beverage liquid L passes, and the liquid nozzle 13 has a liquid flow path 13b through which the liquid L passes and a liquid outlet 13c from which the liquid L flows out after passing through the liquid flow path 13b, and the distance K between the foam outlet 22 and the liquid outlet 13c may be 2 cm or less.

However, if the distance K between the liquid outlet 13c and the foam outlet 22 is too long, it may happen that the beverage container C must be moved in order to pour out the foam B after the liquid L has been poured into the beverage container C. Specifically, after moving the beverage container C under the liquid nozzle 13 and pouring out the liquid L, it is necessary to remove the beverage container C from the liquid nozzle 13 and replace it with the pouring member 20. In other words, after pouring out the liquid L, it becomes necessary to remove the beverage container C from the liquid nozzle 13 and move the beverage container C under the pouring member 20 before pouring out the foam B.

In contrast, when the distance K between the foam outlet 22 and the liquid outlet 13c is 2 cm or less, the foam outlet 22 and the liquid outlet 13c can be brought closer to each other. Therefore, after pouring the liquid L into the beverage container C, the foam B can be poured without moving the beverage container C, making it unnecessary to move the beverage container C. In other words, after pouring the liquid L from the liquid nozzle 13, the foam B can be poured from the foam outlet 22c without replacing the beverage container C from the liquid nozzle 13 to the pouring member 20. Therefore, the pouring operation of the sparkling beverage D can be performed efficiently.

Also, as shown in FIG. 3, the faucet 10 is provided with a liquid nozzle 13 through which the liquid L passes, and the sum of the length N1 of the foam nozzle 14 and the length N2 of the pouring member 20 may be longer than the length N3 of the liquid nozzle 13. In this case, by making the sum of the length N1 of the foam nozzle 14 and the length N2 of the pouring member 20 longer than the length N3 of the liquid nozzle 13, the liquid nozzle 13 can be moved farther away from the liquid surface L1 when pouring out the foam B. Therefore, adhesion of the foam B to the liquid nozzle 13 can be more reliably suppressed.

As shown in FIG. 5, the dispensing member 20 is tubular and extends from the foam nozzle 14 toward the liquid L, and the length Y1 of the foam outlets 22, 22b, 22c in the width direction X1 of the dispensing member 20 may be equal to or greater than the length Y2 of the foam outlets 22, 22b, 22c in the length direction X2 of the dispensing member 20. In this case, by making the horizontal length of the foam outlets 22, 22b, 22c equal to or greater than the vertical length, the foam B to be dispensed does not extend vertically, and there is no disturbance in the flow of the foam B during dispensing, allowing for the dispensing of foam with a good appearance.

Second Embodiment
Next, a beverage server 31 according to a second embodiment will be described. As shown in Fig. 8 and Fig. 9, the beverage server 31 includes, for example, a pouring member 40 different from the above-mentioned pouring member 20. The beverage server 31 includes, for example, a faucet 10 and a pouring member 40 attached to the faucet 10. The beverage server 31 according to the second embodiment has a part of its configuration that is the same as the above-mentioned beverage server 1. Therefore, the description of the parts that overlap with the beverage server 1 will be omitted as appropriate.

The pouring member 40 is made of resin, for example. As an example, the pouring member 40 is produced by injection molding. The pouring member 40 includes, for example, a base 41 extending along the extension direction X3 of the faucet body 12, a clamping portion 42 extending upward from the base 41 and clamping the faucet body 12, and an attachment portion 43 attached to the foam nozzle 14 of the faucet 10. The base 41 is, for example, plate-shaped extending in the extension direction X3 and in the width direction X4 of the faucet body 12 (the depth direction of the paper in FIG. 8).

The base 41 has a through hole 44 through which the liquid nozzle 13 passes and which penetrates in the vertical direction. As an example, the through hole 44 is circular, and the inner diameter of the through hole 44 is larger than the outer diameter of the liquid nozzle 13. The clamping portion 42 clamps the faucet main body 12 with the liquid nozzle 13 passed through the through hole 44, for example.

For example, the clamping portion 42 is located further back (closer to the housing 2) than the mounting portion 43. As an example, the clamping portion 42 includes a pair of arm portions 42b. The pair of arm portions 42b are aligned, for example, along the width direction X4 and extend upward from both ends of the base 41 in the width direction X4. Each arm portion 42b is plate-shaped, and a holding portion 42c for the faucet main body portion 12 is provided at the end of each arm portion 42b opposite the base 41.

The arm portion 42b includes, for example, a root portion 42d in which the width of the arm portion 42b narrows as it moves away from the base 41, a plate-shaped portion 42f extending upward from the root portion 42d, and a holding portion 42c located at the end of the plate-shaped portion 42f opposite the root portion 42d. The holding portion 42c protrudes (curves) inward in the width direction X4 of the base 41 at the upper end of the arm portion 42b. The part of the holding portion 42c protruding inward in the width direction X4 hooks onto the faucet body 12, causing the pair of arms 42b to sandwich the faucet body 12.

Figure 10 is a side view of the dispensing member 40 when viewed along the width direction X4. As shown in Figures 9 and 10, for example, the base 41 extends diagonally downward from the rear side (the housing 2 side) toward the front side. As an example, the mounting portion 43 is located closer to the front than the clamping portion 42.

The mounting portion 43 includes, for example, a foam flow path portion 45 that is continuous with the base 41 and extends downward from the base 41, and a covering portion 46 that covers the foam nozzle 14. The foam flow path portion 45 is provided, for example, at the bottom of the covering portion 46. As an example, the foam flow path portion 45 has a pair of connection portions 45b that are connected to the base 41 and aligned along the width direction X4, an enlarged diameter portion 45c that extends forward from each connection portion 45b, and a flow path forming portion 45d that extends downward from the enlarged diameter portion 45c.

Each connection portion 45b is curved downward, for example, from the end on the front side of the base 41. The enlarged diameter portion 45c connects a pair of connection portions 45b to each other. The enlarged diameter portion 45c is curved, for example, from the lower end of each connection portion 45b toward the front side. As an example, the enlarged diameter portion 45c is curved in an arc shape. For example, the enlarged diameter portion 45c is enlarged in diameter relative to the flow path forming portion 45d above the flow path forming portion 45d.

The covering portion 46 includes, for example, a tubular portion 46b extending upward from the foam flow path portion 45 (expanded diameter portion 45c), a first protruding portion 46c protruding from the tubular portion 46b, a second protruding portion 46d protruding from the first protruding portion 46c, and an air flow path 46f formed in the second protruding portion 46d. As an example, the tubular portion 46b is cylindrical.

The first protrusion 46c, for example, protrudes toward the front from the upper part of the cylindrical portion 46b. As an example, the first protrusion 46c is beak-shaped. For example, the amount of protrusion of the first protrusion 46c from the cylindrical portion 46b increases as it moves upward. The first protrusion 46c has, for example, an inclined surface 46g that extends obliquely toward the front as it moves upward.

The cylindrical portion 46b has an opening 46h, for example, at the end opposite the foam flow path portion 45 (for example, the upper side). As an example, the opening 46h has an arc shape with a central angle of 180° or more. For example, the first protruding portion 46c has an opening 46j that is continuous with the opening 46h, at the end opposite the foam flow path portion 45. As an example, the opening 46j is U-shaped.

The second protrusion 46d, for example, protrudes further forward from the first protrusion 46c. As an example, the second protrusion 46d protrudes in an arc shape. However, the second protrusion 46d may protrude in a rectangular shape, for example, and the protruding shape of the second protrusion 46d is not particularly limited.

Fig. 11 is a cross-sectional view of line A-A in Fig. 10. As shown in Fig. 10 and Fig. 11, the foam flow path section 45 has a foam flow path 45f through which the foam B passes after passing through the foam nozzle 14, and a foam outlet 45g from which the foam B passes after passing through the foam flow path 45f. The foam outlet 45g opens in a direction along the liquid surface, similar to the foam outlet 22 of the pouring member 20, for example. Therefore, the foam B is poured out from the foam outlet 45g in a substantially horizontal direction. The area of the foam outlet 45g is, similar to the area of the foam outlet 22, for example, ⁴⁵ mm2 or more and 75 ^mm2 or less.

As an example, in the mounting portion 43, the covering portion 46 is a separate member from the foam flow path portion 45. In other words, the covering portion 46 is a separate member from the portions other than the covering portion 46 (the base 41, the clamping portion 42, and the foam flow path portion 45). The foam flow path portion 45 has, for example, a recess 45j that is recessed downward inside the enlarged diameter portion 45c.

For example, the covering portion 46 is fitted into the recess 45j of the foam flow path portion 45 to integrate the mounting portion 43. The height of the portion of the covering portion 46 that fits into the recess 45j is, for example, 1.0 mm or more and 7.0 mm or less (for example, about 4.0 mm). For example, the cylindrical portion 46b of the covering portion 46 includes a first cylindrical portion 46k located on the upper side and a second cylindrical portion 46m having an inner diameter smaller than that of the first cylindrical portion 46k. For example, the first cylindrical portion 46k corresponds to the portion into which the foam nozzle 14 is fitted. For example, the inner diameter of the second cylindrical portion 46m is the same as the inner diameter of the foam flow path portion 45 (foam flow path 45f). Therefore, the foam B flowing out of the foam nozzle 14 can be smoothly flowed from the second cylindrical portion 46m into the foam flow path portion 45.

Figure 12 is a front view of the dispensing member 40 as viewed from the front side. Figure 13 is a cross-sectional view of the dispensing member 40 taken along line B-B. As shown in Figures 12 and 13, as an example, at the upper end of each arm portion 42b of the clamping portion 42, the holding portion 42c that holds the faucet main body portion 12 is curved in an arc shape. For example, each of a pair of root portions 42d aligned along the width direction X4 protrudes toward the through hole 44 as it extends downward. As an example, the inner diameter of the through hole 44 increases as it extends downward.

The shape of the first protrusion 46c as viewed from the front side is, for example, U-shaped. The shape of the second protrusion 46d as viewed from the front side is, for example, a straight line extending vertically. As an example, the first protrusion 46c is provided in an area including the center of the width direction X4 of the dispensing member 40, and the second protrusion 46d is provided in an area including the center of the first protrusion 46c in the width direction X4.

Figure 14(a) is a perspective view showing the first cylindrical portion 46k, the first protruding portion 46c, the second protruding portion 46d, and the air flow path 46f. Figure 14(b) is a cross-sectional view of the air flow path 46f. As shown in Figures 13, 14(a), and 14(b), when the spouting member 40 is attached to the faucet 10, the air flow path 46f is connected to, for example, the foam flow path 45f of the foam flow path portion 45. For example, the air flow path 46f extends from the protruding end of the second protruding portion 46d (for example, the front end, upper end) to the lower end of the first protruding portion 46c (for example, the boundary portion between the first cylindrical portion 46k and the second cylindrical portion 46m).

The air flow path 46f extends, for example, along the inner surface 46p of the first protrusion 46c. As an example, the air flow path 46f extends upward relative to the foam flow path 45f. In this disclosure, "upward" includes both vertically upward and diagonally upward. For example, the air flow path 46f has a groove shape that extends linearly diagonally downward from the second protrusion 46d. In this disclosure, "groove shape" refers to a state in which a linear or curved recess extends in a certain direction. The cross section of the air flow path 46f when cut on a plane perpendicular to the extension direction of the air flow path 46f is, for example, semicircular.

The cross-sectional diameter of the air flow path 46f is, for example, 2.0 mm or more and 5.0 mm or less. However, for example, the lower limit of the cross-sectional diameter of the air flow path 46f may be 2.5 mm or 3.0 mm, and the upper limit of the cross-sectional diameter of the air flow path 46f may be 4.5 mm, 4.0 mm, or 3.5 mm. In addition, the value of the diameter of the air flow path 46f is not limited to the above example and can be changed as appropriate.

The cross-sectional depth of the air flow path 46f may be, for example, half the cross-sectional diameter of the air flow path 46f. For example, the cross-sectional depth of the air flow path 46f may be 1.0 mm or more and 2.5 mm or less. In addition, the lower limit of the cross-sectional depth of the air flow path 46f may be 1.5 mm, and the upper limit of the cross-sectional depth of the air flow path 46f may be 2.0 mm. Note that the value of the cross-sectional depth of the air flow path 46f is not limited to the above example and can be changed as appropriate.

The cross-sectional shape of the air flow path 46f is not limited to a semicircular shape, but may be a semi-elliptical shape, a parabolic shape, a rectangular shape, a U-shape, or a V-shape, and can be modified as appropriate. However, when the shape of the inner surface 46q of the air flow path 46f is curved, the production of the discharge member 40 can be performed more easily and dirt can be prevented from accumulating in the air flow path 46f, compared to when the inner surface 46q has corners.

The number of air flow paths 46f may be one or more. By providing the air flow path 46f in communication with the foam flow path 45f in the dispensing member 40, after the foam B has been dispensed, outside air enters the foam flow path 45f from outside the dispensing member 40 via the air flow path 46f. This outside air quickly expels the foam B from the foam flow path 45f, making it possible to suppress the foam B from remaining in the foam flow path 45f.

As described above, in the beverage server 31 and the dispensing member 40 according to the second embodiment, for example as shown in Fig. 8 and Fig. 13, the area of the foam outlet 45g of the dispensing member 40 attached to the foam nozzle ¹⁴ is 45 mm2 or more and ⁷⁵ mm2 or less. Therefore, the area of the foam outlet 45g can be increased to suppress the momentum of the foam B, thereby reducing the possibility of the foam B flying out of the beverage container, and the same effect as that of the first embodiment described above can be obtained.

The beverage server 31 according to the second embodiment is provided with an air flow path 46f that communicates with the foam flow path 45f. Therefore, by providing an air flow path 46f that communicates with the foam flow path 45f through which the foam B passes, the foam B remaining in the foam flow path 45f can be quickly discharged by the air passing through the air flow path 46f. Therefore, when the pouring of the foam B is stopped, the foam B is quickly discharged from the foam flow path 45f, so that dripping, in which the foam B continues to drip for a long period of time, can be suppressed.

In the case of a pouring member that does not have an air flow path 46f, foam B may remain in the foam flow path 45f after the pouring of foam B is stopped, and thus dripping may occur, in which the foam B remaining in the foam flow path 45f continues to drip from the foam outlet 45g for a long time. Dripping may occur for, for example, two minutes or more. Dripping may cause a problem of poor appearance. Furthermore, if dripping occurs, the foam B may get into the beverage container the next time liquid L is poured. If dripping foam B gets into the beverage container when liquid L is poured, the foam B may become a nucleus and cause liquid L to unintentionally foam. Therefore, in order to reliably control the pouring of liquid L and the subsequent pouring of foam B, it may be necessary to suppress dripping.

Therefore, when an air flow path 46f communicating with the foam flow path 45f is formed as in the beverage server 31 according to the second embodiment, air flows from the air flow path 46f into the foam flow path 45f after the dispensing of the foam B is stopped, and the foam B is quickly discharged from the foam flow path 45f and the foam outlet 45g. This prevents the foam B from dripping, improving the appearance and preventing dripping foam B from entering the beverage container the next time liquid L is dispensed. This allows the dispensing of liquid L and the subsequent dispensing of foam B to be reliably controlled, providing a sparkling beverage with good liquid L and foam B dispensed.

Furthermore, when the air flow path 46f is provided, when the faucet 10 to which the dispensing member 40 is attached is removed from the housing 2 and the dispensing member 40 is washed together with the faucet 10, the washability of the foaming agent flow path 45f can be improved by passing water or detergent through the air flow path 46f. In other words, since the air flow path 46f can be used as a flow path for water or detergent when washing the faucet 10 and the dispensing member 40, the foaming agent flow path 45f can be washed efficiently.

The air flow path 46f may also be a groove extending upward relative to the foam flow path 45f. In this case, since the air flow path 46f is a groove extending upward relative to the foam flow path 45f, leakage of the foam B from the foam flow path 45f through the air flow path 46f can be suppressed.

The outlet member 40 may also have an air flow path 46f that communicates with the foam flow path 45f. In this case, since the outlet member 40 has the air flow path 46f, it is not necessary to form an air flow path in the faucet 10, so that an existing faucet can be used as the faucet 10.

The above describes the embodiments of the beverage server and dispensing member according to the present disclosure. However, the beverage server and dispensing member according to the present disclosure are not limited to the above-described embodiments, and may be modified or applied to other things without changing the gist of the claims. The shape, size, number, material, and arrangement of each part of the beverage server and dispensing member can be changed as appropriate without departing from the gist of the above. For example, in the above-described embodiment, a beverage server 1 equipped with two faucets 10 was described. However, the number of faucets equipped in the beverage server may be one or three or more, and can be changed as appropriate.

In the above embodiment, the beverage server 31 is described with a dispensing member 40 having an air passage 46f that communicates with the foam passage 45f. However, the air passage that communicates with the foam passage may be provided in something other than the dispensing member 40. For example, a recess may be formed in the faucet body 12 of the faucet 10 to form an air passage between the faucet body 12 and the dispensing member. In this way, the location where the air passage that communicates with the foam passage is formed can be changed as appropriate. In the above embodiment, the groove-shaped air passage 46f is described. However, the air passage may be, for example, a hole, and the shape, size, number, and arrangement of the air passage are not particularly limited.

(Example)
Next, examples of the beverage server and the dispensing member according to the present disclosure will be described. The present invention is not limited to the following examples. In the experiments according to the examples, for example as shown in FIG. 4, a beverage container C was placed under the dispensing member, and the degree to which the foam B jumped from the dispensing member and the degree to which the foam B penetrated into the liquid surface L1 of the liquid L were measured for each of the dispensing members of Examples 1 and 2 and Comparative Examples 1 to 4 below. In this experiment, the dispensing angle θ2 of the foam B in a plan view was set to 90°. The specifications of the dispensing members of Examples 1 and 2 and Comparative Examples 1 to 4 are as follows.

Example 1
A pouring member having the same shape as the above-mentioned pouring member 20 was used, and the foam B was poured out with the area of the foam outlet being 48.0 ^mm2 .
Example 2
A pouring member having the same shape as the above-mentioned pouring member 20 was used, and the foam B was poured out with the area of the foam outlet being 56.7 ^mm2 .
(Comparative Example 1)
A pouring member having the same shape as the above-mentioned pouring member 20 was used, and the foam B was poured out with the area of the foam outlet being 38.5 ^mm2 .
(Comparative Example 2)
A pouring member having the same shape as the above-mentioned pouring member 20 was used, and the foam B was poured out with the area of the foam outlet being 28.2 ^mm2 .
(Comparative Example 3)
A pouring member having the same shape as the above-mentioned pouring member 20 was used, and the foam B was poured out with the area of the foam outlet being 78.5 ^mm2 .
(Comparative Example 4)
A pouring member having the same shape as the above-mentioned pouring member 20 was used, and the foam B was poured out with the area of the foam outlet being 12.0 ^mm2 .

The results of experiments in which foam B was poured into a beverage container C from each of the pouring members of Examples 1 and 2 and Comparative Examples 1 to 4 are shown in Table 1 below. In Table 1, a case in which the foam B protruded horizontally a distance of 3 cm or more or foam B was observed to sink into the liquid surface L1 was rated "NG", and a case in which the foam B protruded horizontally a distance of less than 3 cm and foam B was not observed to sink into the liquid surface L1 was rated "OK".

As shown in Table 1, when foam B was poured from each of the pouring members of Comparative Example 1, in which the foam outlet area was 38.5 ^mm2, Comparative Example 2, in which the foam outlet area was 28.2 ^mm2 , and Comparative Example 4, in which the foam outlet area was 12.0 ^mm2 , it was found that the momentum of foam B could not be controlled and there was a possibility that foam B would fly out of beverage container C. In Comparative Examples 1, 2, and 4, the distance that foam B flew out horizontally was 5 to 6 cm.

As a result of pouring out foam B from the pouring member of Comparative Example 3, which has a foam outlet area of 78.5 ^mm2 , the large foam outlet area made it possible to suppress the momentum of foam B. However, in the case of the pouring member of Comparative Example 3, the foam outlet area was too large, so much of the foam B fell directly onto the liquid level L1, and foam B was also seen to sink into the liquid level L1.

In contrast, it was found that when foam B was poured from each of the pouring members of Example 1, in which the area of the foam outlet was ^{48.0 mm2} , and Example 2, in which the area of the foam outlet was ^56.7 mm2, the momentum of the foam B could be suppressed and the foam B could be prevented from popping out of the beverage container C. In Examples 1 and 2, the distance that the foam B popped out in the horizontal direction was less than 3 cm. Furthermore, it was found that the pouring members of Examples 1 and 2 could pour the foam B with an appropriate force so as to follow the inner surface C1 of the beverage container C, thereby preventing the foam B from sinking into the liquid level L1.

In addition, to verify the beverage server 31 according to the second embodiment, an experiment was conducted to compare the case where the server has an air flow path 46f communicating with the foam flow path 45f with the case where the server does not have the air flow path 46f. In this experiment, foam B was poured into the beverage container C, and the state of dripping of foam B thereafter was verified. Specifically, the number of times foam B dripped was measured every 60 seconds from the time when the foam B was finished being poured out, 30 seconds and 60 seconds after that. In the following, the case where the pouring member 40 having the air flow path 46f is provided will be described as Example 3, and the case where the pouring member having no air flow path 46f is provided will be described as Comparative Example 5. The results of this experiment in Comparative Example 5 are shown in Table 2 below, and the results of this experiment in Example 3 are shown in Table 3 below.

As shown in Table 2, in Comparative Example 5, even 120 seconds after the stop of the pouring of Foam B, dripping continued at least 10 times per minute, and even after 180 seconds, dripping did not stop. In contrast, in Example 3, the number of drips was reduced to 3 or less by the time 60 seconds had passed, and dripping was reduced to zero at the time 180 seconds had passed. Therefore, it was found that in the case of Example 3, which has air flow path 46f, dripping was significantly reduced compared to Comparative Example 5, which does not have air flow path 46f.

Next, in the beverage server 31 according to the second embodiment, foam B was poured into the beverage container C for each diameter of the air flow path 46f, and an experiment was conducted to verify the state of foam dripping of the foam B thereafter. Table 4 shows the case where the diameter of the air flow path 46f is 2.0 mm, Table 5 shows the case where the diameter of the air flow path 46f is 3.0 mm, Table 6 shows the case where the diameter of the air flow path 46f is 4.0 mm, and Table 7 shows the case where the diameter of the air flow path 46f is 5.0 mm.

In each of Tables 4 to 7, "up to 30 seconds" indicates the number of times that foam B dripped between the time when the dispensing of foam B was completed and 30 seconds, "from 30 seconds to 60 seconds" indicates the number of times that foam B dripped between 30 seconds after the dispensing of foam B was completed and 60 seconds, "from 60 seconds to 120 seconds" indicates the number of times that foam B dripped between 60 seconds after the dispensing of foam B was completed and 120 seconds, and "from 120 seconds to 180 seconds" indicates the number of times that foam B dripped between 120 seconds after the dispensing of foam B was completed and 180 seconds. "Continuous" in Tables 4 to 7 indicates how many seconds after the dispensing of foam B was completed, foam B started to drip not in drops but in a continuous line. "2/60" in Table 5 indicates that a continuous line of foam B occurred 2 seconds and 60 seconds later.

As shown in Table 4 (air flow path 46f diameter 2.0 mm), Table 5 (air flow path 46f diameter 3.0 mm), Table 6 (air flow path 46f diameter 4.0 mm), and Table 7 (air flow path 46f diameter 5.0 mm), when the diameter of the air flow path 46f is 2.0 mm or more and 5.0 mm or less, the number of drips 120 seconds after the pouring of foam B is stopped can be suppressed to 1 or less. In addition, it was found that the linear dripping (continuous) of foam B that occurs after the pouring of foam B is stopped can be reduced when the diameter of the air flow path 46f is large. Furthermore, when the diameter of the air flow path 46f is 4.0 mm or more (Tables 6 and 7), the linear dripping of foam B can be suppressed immediately after foaming is stopped. Therefore, it was found that when the diameter of the air flow path 46f is 4.0 mm or more, linear trailing of the foam B can be suppressed, which is more preferable from the standpoint of suppressing trailing.
