Description

Beverage server and dispensing materials

The present disclosure relates to beverage servers and pouring components.
This application claims the priority based on Japanese Application No. 2019-175705 on September 26, 2019 and the priority based on Japanese Application No. 2020-044583 on March 13, 2020. All the contents described are incorporated.

Various types of beverage servers and injection members for injecting beverages such as beer have been conventionally known. Japanese Patent Laying-Open No. 2018-127280 describes a beverage server and a pouring member. The beverage server is equipped with a curan provided with a lever, and the beer liquid or foam is dispensed by operating the lever. The curan includes a liquid nozzle for pouring out beer liquid and a foam nozzle for pouring out foam.

The dispensing member includes a columnar fitting protrusion attached to the foam nozzle of the curan and a columnar flow path conversion portion whose diameter is expanded at the lower part of the fitting protrusion. A flow path through which beer foam flows is formed inside the fitting protrusion and the flow path conversion part. This flow path extends in a substantially horizontal direction from the first extending portion extending downward from the upper end of the fitting protrusion, the bent portion bent at the lower end of the first extending portion, and the bent portion. It is provided with a second extending portion. At the tip of the second extending portion, an outlet through which beer foam flows out of the pouring member is formed.

The above-mentioned 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 along the liquid level 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 in the vertical direction with respect to the liquid level of the beer liquid. That is, the flow path is formed so that the pouring angle of the beer foam is 0 ° or more and 45 ° or less in the vertical direction with respect to the horizontal direction.

In the above-mentioned dispensing member, the second extending portion of the flow path is bent by the bent portion formed inside the dispensing member. Therefore, the beer foam in the foam nozzle is poured out from the outlet along the liquid level of the beer liquid. By pouring the beer foam along the liquid surface in this way, it is difficult for the beer foam to mix with the beer liquid.

Japanese Unexamined Patent Publication No. 2018-127280

In the above-mentioned injection member, the foam is injected in the substantially horizontal direction by providing the second extending portion in which the flow path extends in the substantially horizontal direction from the bent portion. Therefore, when the foam is poured out, the foam may pop out in the substantially horizontal direction, so that the foam may pop out to the outside of the beverage container. If the foam is vigorously poured out and the foam has a long pop-out distance, the foam may pop out of the beverage container.

It may be difficult to determine the position of the beverage container so that the foam does not jump out of the beverage container, and skill may be required in the operation of pouring the foam. In order to prevent the foam from jumping out of the beverage container, the foam must be dispensed with the lower end of the pouring member close to the liquid surface, so that the foam is placed at the liquid nozzle or the lower end of the pouring member. Is easy to adhere.

If the foam adheres to the lower end of the liquid nozzle or the pouring member, it does not look good and may cause a problem in terms of hygiene. When the foam pops out in a substantially horizontal direction, the foam may collide with the inner surface of the beverage container, and as a result, there may be a problem that the foam easily slips into the liquid surface. Therefore, it is required to suppress the momentum of the foam injected in the substantially horizontal direction.

One aspect of the present disclosure is a beverage server and Note that can suppress the momentum of the foam injected in a substantially horizontal direction, facilitate the injection operation of the foam, and suppress the adhesion of the foam. The purpose is to provide a protruding member.

The beverage server according to one aspect of the present disclosure includes a curan having a foam nozzle through which a beverage foam injected onto a liquid passes, and a foam attached to the foam nozzle and passing through the foam nozzle. Is provided with a pouring member for pouring the liquid onto the liquid. The injection member has a foam flow path through which the foam passes and a foam outlet through which the foam flows out through the foam flow path. The foam outlet is open in the direction along the liquid level of the liquid, and the area of the foam outlet is 45 mm ² or more and 75 mm ² or less.

In this beverage server, the pouring member attached to the foam nozzle of the curan comprises a foam flow path and a foam outlet. The foam from the foam nozzle passes through the foam flow path, and the foam outlet opens in the direction along the liquid level of the liquid. Therefore, the foam that has passed through the foam flow path of the injection member is injected in the substantially horizontal direction from the foam outlet. In this beverage server, the area of the foam outlet is 45 mm ² or more. Since the area of the foam outlet is 45 mm ² or more, the area of the foam outlet can be increased to suppress the momentum of the foam, thus reducing the possibility of the foam jumping out of the beverage container. be able to. Therefore, even if the lever is normally operated, the foam can be prevented from popping out to the outside of the beverage container, so that the foam can be easily poured out even if the person is not skilled. By suppressing the momentum of pouring the foam, it is possible to prevent the foam from jumping out of the beverage container without bringing the lower end of the pouring member close to the liquid surface, so that the liquid nozzle or the lower end of the pouring member can be suppressed. Adhesion of foam to the foam can be suppressed. By suppressing the momentum of the injected foam, it is possible to alleviate the collision of the foam with the inner surface of the beverage container, and thus it is possible to suppress the infiltration of the foam into the liquid surface. Since the area of the foam outlet is 75 mm ² or less, the momentum of the injected foam can be appropriately maintained, so that the foam can be more reliably suppressed from entering the liquid surface. it can.

The curan may include a liquid nozzle through which a beverage passes, and the liquid nozzle may have a liquid flow path through which the liquid passes and a liquid outlet through which the liquid flows out through the liquid flow path. The distance between the foam outlet and the liquid outlet may be 2 cm or less. By the way, 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 eject the foam after the liquid has been poured into the beverage container. sell. On the other hand, as described above, when 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 close to each other. Therefore, after pouring the liquid into the beverage container, the foam can be dispensed without moving the beverage container, and it is not necessary to move the beverage container, so that the beverage pouring operation can be performed efficiently. It can be carried out.

The curan is provided with a liquid nozzle through which a beverage passes, and the total of the length of the foam nozzle and the length of the pouring member may be longer than the length of the liquid nozzle. In this case, the sum of the length of the foam nozzle and the length of the pouring member is longer than the length of the liquid nozzle, so that the liquid nozzle is separated from the liquid surface when pouring the foam. be able to. Therefore, it is possible to more reliably suppress the adhesion of the foam to the liquid nozzle.

The dispensing member may be a tubular shape extending from the foam nozzle toward the liquid surface. The length of the foam outlet in the width direction of the dispensing member may be equal to or greater than the length of the foam outlet in the longitudinal direction of the dispensing member. In this case, if the length of the foam outlet in the horizontal direction is equal to or greater than the length in the vertical direction, the foam to be injected can be prevented from extending in the vertical direction. As a result, it is possible to more reliably suppress the foam from popping out of the beverage container.

The beverage server may be provided with an air flow path communicating with the foam flow path. In this case, by providing an air flow path communicating 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 pouring of the foam is stopped, the foam is quickly discharged from the foam outlet, so that it is possible to suppress the post-dripping of the foam that continues to drip for a long time.

The air flow path may have a groove shape extending upward with respect to the foam flow path. In this case, since the air flow path has a groove shape extending upward with respect to the foam flow path, it is possible to prevent the foam from leaking from the foam flow path through the air flow path.

The pouring member according to one aspect of the present disclosure is a pouring member attached to a nozzle for foam of curan through which a foam of a beverage to be poured onto a liquid passes. The pouring member has a foam flow path through which the foam passes through the foam nozzle and a foam outlet through which the foam flows out through the foam flow path. The foam outlet is open in the direction along the liquid level of the liquid, and the area of the foam outlet is 45 mm ² or more and 75 mm ² or less.

This pouring member includes a foam flow path and a foam outlet, and the foam outlet opens in a direction along the liquid level. Therefore, the foam is poured out substantially horizontally from the foam outlet. In this pouring member, since the area of the foam outlet is 45 mm ² or more, the area of the foam outlet can be increased to suppress the momentum of the foam. Therefore, as with the beverage server described above, the possibility that the foam will jump out of the beverage container can be reduced. Therefore, the foam can be easily poured out even if the person is not skilled, and the foam can be suppressed from popping out to the outside of the beverage container even if the lower end of the pouring member is not brought close to the liquid surface. As a result, it is possible to suppress the adhesion of the foam to the lower end of the liquid nozzle or the pouring member. Since the momentum of the injected foam can be suppressed and the collision of the foam with the inner surface of the beverage container can be alleviated, it is possible to suppress the infiltration of the foam into the liquid surface. Since the area of the foam outlet is 75 mm ² or less, the momentum of the injected foam can be appropriately maintained, so that the foam can be more reliably suppressed from entering the liquid surface. it can.

The pouring member may be provided with an air flow path communicating with the foam flow path. In this case, as in the case of the beverage server described above, the remaining foam can be quickly discharged by the air passing through the air flow path, so that the dripping of the foam can be suppressed. Since the injection member is provided with the air flow path, it is not necessary to form the air flow path in the curan, so that the existing curan can be used.

According to one aspect of the present disclosure, it is possible to suppress the momentum of the foam injected in a substantially horizontal direction, facilitate the injection operation of the foam, and suppress the adhesion of the foam.

Hereinafter, embodiments of the beverage server and the dispensing member according to one aspect of the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate description will be omitted as appropriate. For ease of understanding, the drawings may be partially simplified or exaggerated, and the dimensional ratios, angles, etc. are not limited to those described in the drawings.

(First Embodiment)
FIG. 1 is a perspective view showing the appearance of the beverage server 1 according to the first embodiment. FIG. 2 is a perspective view showing an example of a state in which a beverage is poured out from the curan 10 of the beverage server 1. The beverage server 1 is, for example, a device provided in a restaurant, and can dispense beverages by operating a lever 11 in response to a customer's order or the like.

The beverage is, for example, effervescent beverage D. The effervescent beverage D includes, for example, a gas-containing fermented liquor such as carbon dioxide. The effervescent beverage D has, for example, a foaming property in which a layer of foam B is formed on the liquid L when poured into a beverage container C, and foaming in which the formed foam B is maintained for a certain period of time or longer. It is a beverage having characteristics.

Happoshu Beverage D is, for example, a beverage having an NIBEM value of 50 seconds or more according to the EBC (European Brewery Convention) method. The NIBEM value is an index value indicating the foaming characteristics of the beverage. The sparkling beverage D may be a beer-taste beverage. Beer-taste beverages include beverages that taste like beer and beverages that give the drinker the sensation of drinking beer. A beer-taste beverage having an alcohol content of 1% or more is also called a beer-taste alcoholic beverage.

Beer-taste beverages include fermented malt beverages such as beer that uses malt as a raw material, sparkling liquor, non-alcoholic beer, liqueur (for example, beverages classified as "liqueur (foaming) (1)" under the Liquor Tax Law). Includes beer-taste beverages that do not use wheat or malt as raw materials (for example, beverages classified as "other brewed liquor (foaming) (1)" under the Liquor Tax Law). The sparkling beverage D may be a beverage that is not a beer-taste beverage. Hereinafter, an example in which the liquid L is a beer liquid and the sparkling beverage D is beer will be described.

For example, the beverage server 1 includes a plurality of (two as an example) currants 10. The beverage server 1 can provide a plurality of types (two types as an example) of beverages. The curan 10 is attached to the housing 2 of the beverage server 1. For example, a beverage hose is connected to the beverage server 1, and a beverage is 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.

FIG. 3 is a side view schematically showing the curan 10. As shown in FIGS. 2 and 3, for example, the curan 10 includes a lever 11 that can be gripped and moved by hand, a curan body 12 to which the lever 11 is attached, a liquid nozzle 13, and a foam. A nozzle 14 and the like are provided. The curan body 12 is fixed to the housing 2. The liquid nozzle 13 extends diagonally downward from the curan main body 12, and the foam nozzle 14 is located on the opposite side of the housing 2 when viewed from the liquid nozzle 13. In FIG. 3, the internal structure of the curan main body 12 is shown in a simplified manner.

The lever 11 is, for example, the opposite side of the housing 2 when the user is located on the opposite side of the housing 2 (the front side of the beverage server 1, for example, the right side of the paper in FIGS. 2 and 3) when viewed from the curan 10. It can be moved to both the side and the housing 2 side (back side, for example, the left side of the paper in FIGS. 2 and 3). In the following, the opposite side of the housing 2 as viewed from the curan 10 may be referred to as the front side, and the housing 2 side may be referred to as the back side. The lever 11 has, for example, a columnar shape, and extends upward from the curan body portion 12. As an example, the lever 11 has a shape in which the diameter gradually increases toward the upper side.

The curan body portion 12 includes, for example, a tubular portion 12b provided with a lever 11, a liquid nozzle 13 and a foam nozzle 14, and a mounting portion 12c whose diameter is increased on the opposite side of the tubular portion 12b from the lever 11. Be prepared. As an example, the mounting portion 12c is mounted on the protruding portion 2b protruding toward the front side in the housing 2.

For example, the mounting portion 12c is rotatable with respect to the tubular portion 12b. As an example, the mounting portion 12c rotates in one direction (for example, clockwise) with respect to the tubular portion 12b and is mounted on the housing 2. The mounting portion 12c can be removed from the housing 2 by rotating in the opposite direction (for example, counterclockwise) of the tubular portion 12b.

Inside the curan main body 12, a slide valve 12d for opening and closing the flow path of the liquid L located inside the curan main body 12 is provided. For example, when the lever 11 moves to the front side, the slide valve 12d moves to the back side and the liquid L is poured out from the liquid nozzle 13. When the lever 11 moves to the back side, the slide valve 12d moves to the front side and the foam B flows into the foam nozzle 14.

The liquid nozzle 13 has, for example, a tubular shape, and is inclined toward the front side (foam nozzle 14 side) as it is separated from the curan body portion 12. As an example, the liquid nozzle 13 has a cylindrical shape and may be tapered toward the tip. However, the shape of the liquid nozzle 13 is not limited to the above example and can be changed 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 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 communicates with the flow path 12f through which the liquid L passes inside the curan main body 12.

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

The beverage server 1 includes a pouring member 20 for pouring out the foam B through the foam nozzle 14. The dispensing member 20 is attached to the foam nozzle 14, and the foam B that has passed through the foam nozzle 14 is dispensed onto the liquid L. The injection member 20 has a hollow structure having a foam flow path 21 through which the foam B passes.

For example, the dispensing member 20 has a bottomed tubular shape. As an example, the dispensing member 20 has a bottomed cylindrical shape, and may be tapered toward the tip 20b of the dispensing member 20 (as it moves away from the foam nozzle 14). In this case, the outer peripheral surface 20c of the dispensing member 20 is reduced in diameter toward the tip 20b. However, the shape of the injection member 20 is not limited to the above example and can be changed as appropriate. As an example, the inner diameter of the pouring member 20 may be the same as the diameter of the foam outlet 22 described later.

The total of the length N1 of the foam nozzle 14 and the length N2 of the dispensing member 20 is longer than, for example, 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 the length N1 from the base portion of the foam nozzle 14 to the curan main body 12 with the pouring member 20. The length to the boundary portion may be shown. For example, the length N2 indicates the distance from the base end 20f of the pouring member 20 to the tip end 20b, and the length N3 is from the base of the liquid nozzle 13 to the curan body 12 to the liquid outlet 13c. Shows the length.

The value of the sum of the length N1 and the length N2 is, for example, 1.5 times or less the value of the length N3. Further, the value of the sum of the length N1 and the length N2 may be 1.4 times or less, 1.3 times or less, 1.2 times or less, or 1.1 times or less the value of the length N3. The value of the sum of the length N1 and the length N2 may be the same as the value of the length N3 or may be smaller than the value of the 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 pouring member 20 may be attached to the foam nozzle 14 by fitting so that the inner peripheral surface of the pouring member 20 comes into contact with the outer peripheral surface of the foam nozzle 14. When the pouring member 20 is attached to the foam nozzle 14 by fitting, the configuration of the pouring member 20 can be simplified, and the pouring member 20 can be easily pushed by pushing the pouring member 20 into the foam nozzle 14. Can be attached to. The pouring member 20 may be attached to the foam nozzle 14 by means other than fitting, such as screwing with a screw. The injection 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 through which the foam B flows out through the foam flow path 21. As shown in FIGS. 3 and 4, the foam outlet 22 opens in the direction along the liquid level L1 of the liquid L. Therefore, the foam B is poured out from the foam outlet 22 in the substantially horizontal direction.

In the foam outlet 22, for example, the pouring angle of the foam B (the angle of the foam B immediately after being poured from the foam outlet 22 with respect to the liquid L) is 0 ° or more up and down with respect to the liquid L. It may be formed so as to have an angle of 45 ° or less. The foam outlet 22 is directed in a direction of 0 ° or more and 45 ° or less up and down with respect to the liquid level L1 of the liquid L, for example.

The angle at which the foam outlet 22 is directed may be 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. The angle at which the foam outlet 22 is directed may 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.

FIG. 5A is an enlarged side view of the liquid nozzle 13 and the pouring member 20. As shown in FIG. 5A, the liquid nozzle 13 and the pouring member 20 extend, for example, so as to approach each other toward the tip. The liquid outlet 13c of the liquid nozzle 13 and the tip 20b of the pouring 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 (a location away 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 distance between the centers 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 dispensing 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 curan body 12 (the direction in which the liquid nozzle 13 and the pouring member 20 are lined up) is, for example, 2 cm or less, similar to the difference H. The distance W may be 1.5 cm or less, 1 cm or less, or 0.5 cm or less. Further, the liquid nozzle 13 and the pouring member 20 may be integrated.

For example, the width A of the foam outlet 22 is larger 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 is, 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 has a circular shape, in which case the width A corresponds to the diameter of the foam outlet 22.

As shown in FIGS. 5 (b), (c) and (d), the shape of the foam outlet of the injection member 20 can be changed as appropriate. For example, the pouring member 20 may include 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. ..

The pouring member 20 may include a rectangular foam outlet 22c instead of the foam outlet 22. For example, the length Y1 of the foam outlets 22, 22b, 22c in the width direction X1 of the pouring 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 pouring member 20. Is. The dispensing member 20 may have a foam outlet 22d in which the 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 ejection of the foam B in a plan view will be described with reference to FIGS. 6 and 7. As shown in FIG. 6, the injection angle of the foam B with respect to the reference line Z passing through the curan main body 12 and the housing 2 is, for example, larger than 0 ° and smaller than 180 °.

When the foam B is dispensed to the right side of the reference line Z in a plan view, the injection angle θ1 of the foam B with respect to the reference line Z is 70 ° or more and 110 ° or less, 85 ° or more and 95 ° or less, 110. It may be greater than or equal to ° and not less than 150 °, or more than or equal to 125 ° and less than or equal to 135 °. The injection angle θ1 may be 90 °.

When the foam B is poured out to the left side of the reference line Z in a plan view, the pouring angle θ2 of the foam B with respect to the reference line Z is 70 ° or more and 110 ° or less, 85 °, like the pouring angle θ1. It may be more than 95 ° and less than 95 °, more than 110 ° and less than 150 °, or more than 125 ° and less than 135 °. The injection angle θ2 may be 90 °. When the pouring angle θ1 and the pouring angle θ2 are within the above angles, the foam B can be pouring out along the inner surface C1 of the beverage container C. As a result, it is possible to suppress the infiltration of the foam B into the liquid surface L1 and the tapping of the foam B into the liquid surface L1.

As shown in FIGS. 7A and 7B, the foam B may be dispensed to the left side or the right side with respect to the beverage container C. The foam B is, for example, injected obliquely with respect to the reference line Z. In this case, since the collision of the foam B with the inner surface C1 of the beverage container C can be alleviated, it is possible to suppress the hitting of the foam B into the liquid L and the infiltration of the foam B.

As an example, when the beverage container C is gripped by the right hand, the foam B is dispensed to the left side, and when the beverage container C is gripped by the left hand, the foam B is dispensed to the right side. As yet another example, when the pouring member 20 is located on the back side (housing 2 side) of the beverage container C, the pouring angles θ1 and θ2 are larger than 90 ° and less than 180 °, and the pouring is performed. When the member 20 is located on the front side of the beverage container C (opposite side of the housing 2), the pouring angles θ1 and θ2 are larger than 0 ° and less than 90 °.

Next, the effects of the beverage server 1 and the dispensing member 20 according to the present embodiment will be described in detail. As shown in FIGS. 4 and 5, in the beverage server 1 and the pouring member 20, the pouring member 20 attached to the foam nozzle 14 of the curan 10 is the foam flow path 21 and the foam outlet 22. To be equipped. The foam B from the foam nozzle 14 passes through the foam flow path 21, and the foam outlet 22 opens in the direction along the liquid level L1 of the liquid L. Therefore, the foam B that has passed through the foam flow path 21 of the injection member 20 is injected in the substantially horizontal direction from the foam outlet 22.

In the beverage server 1, the area of the foam outlet 22 is 45 mm ² or more. Since the area of the foam outlet 22 is 45 mm ² or more, the area of the foam outlet 22 can be increased to suppress the momentum of the foam B, so that the foam B is outside the beverage container C. It is possible to reduce the possibility of popping out.

Therefore, even if the lever 11 is normally operated, the foam B can be prevented from popping out to the outside of the beverage container C, so that the foam B can be easily poured out even if the user is not skilled. Can be done. Further, since the momentum of pouring the foam B is suppressed, it is possible to suppress the foam B from popping out of the beverage container C without bringing the tip 20b, which is the lower end of the pouring member 20, close to the liquid level L1. .. Therefore, it is possible to suppress the adhesion of the foam B to the lower end of the liquid nozzle 13 or the pouring member 20.

By suppressing the momentum of the injected foam B, it is possible to alleviate the collision of the foam B with the inner surface C1 of the beverage container C, so that it is possible to suppress the infiltration of the foam B into the liquid surface L1. .. Since the area of the foam outlet 22 is 75 mm ² or less, the momentum of the injected foam B can be appropriately maintained, so that the foam B can more reliably slip into the liquid level L1. It can be suppressed.

The curan 10 may include a liquid nozzle 13 through which the liquid L of the beverage passes. The liquid nozzle 13 may have a liquid flow path 13b through which the liquid L passes and a liquid outlet 13c through which the liquid L flows out through the liquid flow path 13b. The distance K between the foam outlet 22 and the liquid outlet 13c may be 2 cm or less.

By the way, when the distance K between the liquid outlet 13c and the foam outlet 22 is too long, the beverage container C is moved to eject the foam B after the liquid L has been poured into the beverage container C. It can happen that you have to. Specifically, it is necessary to move the beverage container C under the liquid nozzle 13 to dispense the liquid L, and then remove the beverage container C from the liquid nozzle 13 and replace it with the injection member 20. That is, after pouring out the liquid L, it is 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.

On the other hand, 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 close to each other. Therefore, after the liquid L is poured into the beverage container C, the foam B can be poured out without moving the beverage container C, and the movement of the beverage container C can be unnecessary. That is, the foam B can be dispensed from the foam outlet 22c without replacing the beverage container C with the pouring member 20 from the liquid nozzle 13 after pouring the liquid L from the liquid nozzle 13. .. Therefore, the pouring operation of the sparkling beverage D can be efficiently performed.

As shown in FIG. 3, the curan 10 includes a liquid nozzle 13 through which the liquid L passes, and the total of the length N1 of the foam nozzle 14 and the length N2 of the pouring member 20 is the liquid nozzle 13. It may be longer than the length N3 of. In this case, since the total of the length N1 of the foam nozzle 14 and the length N2 of the pouring member 20 is longer than the length N3 of the liquid nozzle 13, when pouring the foam B, the liquid is used. The nozzle 13 can be separated from the liquid level L1 at a position farther away. Therefore, the adhesion of the foam B to the liquid nozzle 13 can be more reliably suppressed.

As shown in FIG. 5, the dispensing member 20 may have a tubular shape extending from the foam nozzle 14 toward the liquid L. 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. You may. In this case, the length of the foam outlets 22, 22b, 22c in the horizontal direction is equal to or longer than the length in the vertical direction, so that the foam B to be poured out can be prevented from extending in the vertical direction. Then, there is no turbulence in the flow of the foam B at the time of pouring, and the foam having a good appearance can be pouring out.

(Second Embodiment)
Next, the beverage server 31 according to the second embodiment will be described. As shown in FIGS. 8 and 9, the beverage server 31 includes, for example, a dispensing member 40 different from the dispensing member 20 described above. The beverage server 31 includes, for example, a curan 10 and a pouring member 40 attached to the curan 10. The beverage server 31 according to the second embodiment has the same configuration as the beverage server 1 described above in a part thereof. Therefore, the description of the portion overlapping with the beverage server 1 will be omitted as appropriate.

The dispensing member 40 is made of resin, for example. As an example, the injection member 40 is manufactured by injection molding. The injection member 40 includes, for example, a base 41 extending along the extending direction X3 of the curan main body 12, a holding portion 42 extending upward from the base 41 and holding the curan main body 12, and foaming of the curan 10. A mounting portion 43 mounted on the body nozzle 14 is provided. The base 41 has a plate shape extending in the extending direction X3 and the width direction X4 of the curan main body 12 (the depth direction of the paper surface in FIG. 8), for example.

The base 41 has, for example, a through hole 44 through which the liquid nozzle 13 is passed and penetrates in the vertical direction. As an example, the through hole 44 has a circular shape, and the inner diameter of the through hole 44 is larger than the outer diameter of the liquid nozzle 13. The sandwiching portion 42 sandwiches the curan main body portion 12 in a state where the liquid nozzle 13 is passed through the through hole 44, for example.

For example, the holding portion 42 is located on the back side (housing 2 side) of the mounting portion 43. As an example, the sandwiching portion 42 includes a pair of arm portions 42b. The pair of arm portions 42b are arranged along the width direction X4, for example, and extend upward from both ends of the width direction X4 of the base 41. Each arm portion 42b has a plate shape, and a holding portion 42c with respect to the curan main body portion 12 is provided at an end portion of each arm portion 42b on the opposite side of 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 the distance from the base 41 increases, a plate-shaped portion 42f extending upward from the root portion 42d, and a root portion 42d of the plate-shaped portion 42f. It includes a holding portion 42c located at the opposite end. The holding portion 42c projects (curves) inward in the width direction X4 of the base 41 at the upper end of the arm portion 42b. A portion of the holding portion 42c protruding inward in the width direction X4 is caught by the curan main body 12, so that the pair of arm portions 42b sandwich the curan main body 12.

FIG. 10 is a side view of the dispensing member 40 as viewed along the width direction X4. As shown in FIGS. 9 and 10, for example, the base 41 extends diagonally downward from the back side (housing 2 side) toward the front side. As an example, the mounting portion 43 is located closer to the holding 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, in the lower part of the covering portion 46. As an example, the foam flow path portion 45 has a pair of connecting portions 45b connected to the base 41 and arranged along the width direction X4, a diameter-expanded portion 45c extending from each connecting portion 45b to the front side, and a diameter-expanded portion 45c. It has a flow path forming portion 45d extending downward from the surface.

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

The covering portion 46 is formed on, for example, a tubular portion 46b, a first protruding portion 46c protruding from the tubular portion 46b, a second protruding portion 46d protruding from the first protruding portion 46c, and a second protruding portion 46d. It is provided with an air flow path 46f. As an example, the tubular portion 46b extends upward from the foam flow path portion 45 (diameter-expanded portion 45c). For example, the tubular portion 46b has a cylindrical shape.

The first protruding portion 46c protrudes from the upper portion of the tubular portion 46b toward the front side, for example. The first protruding portion 46c has a beak shape as an example. For example, the amount of protrusion of the first protruding portion 46c from the tubular portion 46b increases as it goes upward. The first protruding portion 46c has, for example, an inclined surface 46g that extends obliquely toward the front side as it goes upward.

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

The second protruding portion 46d protrudes further toward the front side from, for example, the first protruding portion 46c. As an example, the second protruding portion 46d protrudes in an arc shape. However, the second protruding portion 46d may project in a rectangular shape, for example, and the protruding shape of the second protruding portion 46d is not particularly limited.

FIG. 11 is a cross-sectional view taken along the line AA of FIG. As shown in FIGS. 10 and 11, the foam flow path portion 45 is formed by foaming through the foam flow path 45f through which the foam B passes through the foam nozzle 14 and the foam flow path 45f. It has a foam outlet (45 g) from which the body B flows out. The foam outlet 45g, like the foam outlet 22 of the pouring member 20, opens in the direction along the liquid level of the liquid, for example. Therefore, the foam B is poured out in the substantially horizontal direction from the foam outlet 45 g. The area of the foam outlet 45 g is, for example, 45 mm ² or more and 75 mm ² or less, similar to the area of the foam outlet 22.

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

For example, the mounting portion 43 is integrated by fitting the covering portion 46 into the recess 45j of the foam flow path portion 45. 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). As an example, the tubular portion 46b of the covering portion 46 includes a first tubular portion 46k located on the upper side and a second tubular portion 46m having an inner diameter smaller than that of the first tubular portion 46k. For example, the first tubular portion 46k corresponds to a portion into which the foam nozzle 14 is fitted. For example, the inner diameter of the second cylinder portion 46 m 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 poured from the second cylinder portion 46 m into the foam flow path portion 45.

FIG. 12 is a front view of the dispensing member 40 as viewed from the front side. FIG. 13 is a sectional view taken along line BB of the pouring member 40. As shown in FIGS. 12 and 13, as an example, at the upper end of each arm portion 42b of the holding portion 42, the holding portion 42c holding the curan main body portion 12 is curved in an arc shape. For example, each of the pair of root portions 42d arranged along the width direction X4 projects downward toward the through hole 44 side. As an example, the inner diameter of the through hole 44 increases downward.

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

FIG. 14A is a perspective view showing the first tubular portion 46k, the first protruding portion 46c, the second protruding portion 46d, and the air flow path 46f. FIG. 14B is a cross-sectional view of the air flow path 46f. As shown in FIGS. 13 and 14, in a state where the injection member 40 is attached to the curan 10, the air flow path 46f communicates with, for example, the foam flow path 45f of the foam flow path portion 45. There is. For example, the air flow path 46f is from the protruding end of the second protruding portion 46d (for example, the front end and the upper end) to the lower end of the first protruding portion 46c (for example, the first cylinder portion 46k and the second cylinder portion 46m). It extends to the boundary with).

The air flow path 46f extends along the inner surface 46p of the first protrusion 46c, for example. As an example, the air flow path 46f extends upward with respect to the foam flow path 45f. In the present disclosure, "upward" includes both vertically above and diagonally above. For example, the air flow path 46f has a groove shape extending diagonally downward from the second protrusion 46d. In the present disclosure, "groove-shaped" means a state in which a linear or curved concave portion extends in a certain direction. The cross section when the air flow path 46f is cut in a plane orthogonal to the extending direction of the air flow path 46f is, for example, a semicircle.

The diameter of the cross section 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 diameter of the cross section of the air flow path 46f may be 2.5 mm or 3.0 mm, and the upper limit of the diameter of the cross section of the air flow path 46f is 4.5 mm, 4.0 mm or 3.5 mm. It may be. 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 depth of the cross section of the air flow path 46f may be, for example, half the diameter of the cross section of the air flow path 46f. For example, the depth of the cross section of the air flow path 46f may be 1.0 mm or more and 2.5 mm or less. Further, 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. The value of the depth of the cross section 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 appropriately changed. However, when the shape of the inner surface 46q of the air flow path 46f is a curved surface, the pouring member 40 can be easily manufactured and the air flow can be performed as compared with the case where the inner surface 46q has a corner portion. Dirt can be further prevented from accumulating on the road 46f.

The number of air flow paths 46f may be singular or plural. By providing the air flow path 46f in which the injection member 40 communicates with the foam flow path 45f, the foam B is poured into the foam flow path 45f via the air flow path 46f after the foam B has been discharged. Outside air enters from the outside of the member 40. Since the foam B is rapidly discharged from the foam flow path 45f by this outside air, it is possible to suppress the residual foam B in the foam flow path 45f.

As described above, in the beverage server 31 and the pouring member 40 according to the second embodiment, as shown in FIGS. 8 and 13, for example, the foam outlet 45g of the pouring member 40 attached to the foam nozzle 14 The area is 45 mm ² or more and 75 mm ² or less. Therefore, since the area of the foam outlet 45 g can be increased to suppress the momentum of the foam B, the possibility that the foam B jumps out of the beverage container can be reduced, and the above-mentioned first embodiment can be reduced. The same effect as is obtained.

The beverage server 31 according to the second embodiment includes an air flow path 46f communicating with the foam flow path 45f. Therefore, by providing the air flow path 46f communicating with the foam flow path 45f through which the foam B passes, the foam B remaining in the foam flow path 45f is quickly discharged by the air passing through the air flow path 46f. can do. Therefore, when the pouring of the foam B is stopped, the foam B is quickly discharged from the foam flow path 45f, so that it is possible to suppress the post-dripping of the foam B that continues to hang for a long time.

If the injection member does not have the air flow path 46f, the foam B may remain in the foam flow path 45f after the injection of the foam B is stopped. Then, the foam B remaining in the foam flow path 45f may continue to drip from the foam outlet 45 g for a long time, resulting in post-dripping. Back dripping can occur, for example, for more than 2 minutes. When dripping occurs, the problem of unsightly appearance can occur. If the back dripping occurs, the foam B due to the back dripping may enter the next time the liquid L is poured into the beverage container. If the back-dripping foam B enters during the pouring of the liquid L, there may be a problem that the liquid L unintentionally foams with the foam B as a nucleus. Therefore, in order to reliably control the injection of the liquid L and the subsequent injection of the foam B, it may be necessary to suppress the back dripping.

Therefore, when the air flow path 46f communicating with the foam flow path 45f is formed as in the beverage server 31 according to the second embodiment, the air flow path 46f is formed after the pouring of the foam B is stopped. Air enters the foam flow path 45f. As a result, the foam B is quickly discharged from the foam flow path 45f and the foam outlet 45g. Therefore, since the back dripping of the foam B can be suppressed, the appearance can be improved, and the foam B of the back dripping can be prevented from entering the next time the liquid L is poured into the beverage container. it can. Therefore, since the pouring of the liquid L and the subsequent pouring of the foam B can be reliably controlled, it is possible to provide a good effervescent beverage in which the liquid L and the foam B are poured.

When the air flow path 46f is provided, when the curan 10 to which the pouring member 40 is attached is removed from the housing 2 and the pouring member 40 is cleaned together with the curan 10, water or detergent is passed through the air flow path 46f. Therefore, the detergency of the foam flow path 45f can be improved. That is, since the air flow path 46f can be used as a water or detergent flow path when cleaning the curan 10 and the pouring member 40, the foam flow path 45f can be efficiently cleaned.

The air flow path 46f may have a groove shape extending upward with respect to the foam flow path 45f. In this case, since the air flow path 46f has a groove shape extending upward with respect to the foam flow path 45f, it is possible to prevent the foam B from leaking from the foam flow path 45f via the air flow path 46f. can do.

The injection member 40 may include an air flow path 46f communicating with the foam flow path 45f. In this case, since the pouring member 40 includes the air flow path 46f, it is not necessary to form the air flow path in the curan 10, so that the existing curan can be used as the curan 10.

The embodiment of the beverage server and the dispensing member according to one aspect of the present disclosure has been described above. However, the beverage server and the dispensing member according to the present disclosure are not limited to the above-described embodiments, and are modified or applied to other objects without changing the gist described in each claim. There may be. The shape, size, number, material, and arrangement of each part of the beverage server and the pouring member can be appropriately changed without departing from the above gist. For example, in the above-described embodiment, the beverage server 1 including the two currants 10 has been described. However, the number of currants provided in the beverage server may be one or three or more, and can be changed as appropriate.

In the above-described embodiment, the beverage server 31 including the injection member 40 having the air flow path 46f communicating with the foam flow path 45f has been described. However, the air flow path communicating with the foam flow path may be provided in something other than the injection member 40. For example, an air flow path may be formed between the curan main body 12 and the pouring member by forming a recess in the curan main body 12 of the curan 10. As described above, the location where the air flow path communicating with the foam flow path is formed can be appropriately changed. Further, in the above-described embodiment, the groove-shaped air flow path 46f has been described. However, the air flow path may be, for example, a hole, and the shape, size, number, and arrangement mode of the air flow path are not particularly limited.

(Example)
Subsequently, an example of the beverage server and the dispensing member according to one aspect of the present disclosure will be described. The present invention is not limited to the following examples. In the experiment according to the embodiment, for example, as shown in FIG. 4, the beverage container C is arranged under the pouring member, the degree of flying of the foam B from the pouring member, and the liquid level L1 of the liquid L. The degree of penetration of the foam B was measured. The measurement was performed on each of the injection members of Examples 1 and 2 and Comparative Examples 1 to 4 below. In this experiment, the injection angle θ2 of the foam B in a plan view was set to 90 °. The specifications of the dispensed members of Examples 1 and 2 and Comparative Examples 1 to 4 are as follows.

(Example 1)
Using an injection member having the same shape as the above-mentioned injection member 20, the foam ^{B was injected with the area of the foam outlet set to 48.0 mm 2.}
(Example 2)
Using an injection member having the same shape as the above-mentioned injection member 20, the foam ^{B was injected with the area of the foam outlet set to 56.7 mm 2.}
(Comparative Example 1)
Using an injection member having the same shape as the above-mentioned injection member 20, the foam ^{B was injected with the area of the foam outlet set to 38.5 mm 2.}
(Comparative Example 2)
Using an injection member having the same shape as the above-mentioned injection member 20, the foam ^{B was injected with the area of the foam outlet set to 28.2 mm 2.}
(Comparative Example 3)
Using an injection member having the same shape as the above-mentioned injection member 20, the foam ^{B was injected with the area of the foam outlet set to 78.5 mm 2.}
(Comparative Example 4)
Using an injection member having the same shape as the above-mentioned injection member 20, the foam ^{B was injected with the area of the foam outlet set to 12.0 mm 2.}

Table 1 below shows the results of an experiment in which the foam B was injected into the beverage container C from the respective injection members of Examples 1 and 2 and Comparative Examples 1 to 4. In Table 1, the case where the horizontal protrusion distance of the foam B is 3 cm or more, or the case where the foam B is found to sneak into the liquid surface L1 is regarded as “NG”. Then, the case where the horizontal protrusion distance of the foam B was less than 3 cm and the foam B did not submerge into the liquid surface L1 was regarded as "OK".

As shown in Table 1, the area of the foam outlet is Comparative Example 1 is 38.5 mm ^2, the area of the foam outlet is Comparative Example is 28.2 mm ² 2, and the area of the foam outlet As a result of injecting the foam B from each of the injection members of Comparative Example 4 having a size of 12.0 mm ^{2, the momentum of the foam B could not be suppressed.} Therefore, in Comparative Example 1, Comparative Example 2, and Comparative Example 4, it was found that the foam B may protrude to the outside of the beverage container C. In Comparative Example 1, Comparative Example 2 and Comparative Example 4, the distance of the foam B protruding in the horizontal direction was 5 to 6 cm.

As a result of injecting the foam B from the injection member of Comparative Example 3 in which the area of the foam outlet is 78.5 mm ² , the momentum of the foam B can be suppressed due to the large area of the foam outlet. It was. However, in the case of the injection member according to Comparative Example 3, since the area of the foam outlet is too large, there are many foams B that directly fall to the liquid surface L1, and the foam B sneaks into the liquid surface L1. It was.

On the other hand, the foam B is provided from each of the pouring members of Example 1 in which the area of the foam outlet is 48.0 mm ² and Example 2 in which the area of the foam outlet is 56.7 mm ^2. It was found that when pouring out, the momentum of the foam B could be suppressed and the foam B could be suppressed from popping out of the beverage container C. In Examples 1 and 2, the distance of the foam B protruding in the horizontal direction was less than 3 cm. Further, in the dispensing members of Examples 1 and 2, the foam B can be dispensed with an appropriate force along the inner surface C1 of the beverage container C, so that the foam B can be suppressed from slipping into the liquid surface L1. I found out.

In order to verify the beverage server 31 according to the second embodiment, an experiment was conducted in which a case having an air flow path 46f communicating with the foam flow path 45f and a case having no air flow path 46f were compared. In this experiment, the foam B was poured into the beverage container C, and the state of the subsequent dripping of the foam B was verified. Specifically, the number of times the foam B drips was measured every 30 seconds from the time when the pouring of the foam B was completed and every 60 seconds from the time when 60 seconds had passed. Hereinafter, the case where the injection member 40 having the air flow path 46f is provided will be described as Example 3, and the case where the injection member without the 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, the back dripping continued 10 times or more per minute even after 120 seconds had passed since the injection of the foam B was stopped, and the back dripping continued even after 180 seconds had passed. It didn't disappear. On the other hand, in Example 3, the number of back drips could be suppressed to 3 times or less by the time when 60 seconds had passed, and the number of back drips could be set to 0 when 180 seconds had passed. Therefore, in the case of Example 3 having the air flow path 46f, it was found that the back dripping can be remarkably reduced as compared with Comparative Example 5 having no air flow path 46f.

Subsequently, in the beverage server 31 according to the second embodiment, the foam B is poured into the beverage container C for each diameter of the air flow path 46f, and the subsequent state of foam dripping of the foam B is verified. I conducted an experiment to do. 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, and Table 6 shows the case where the diameter of the air flow path 46f is 4.0 mm. 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" is the number of times foam B drips from the time when the injection of foam B is completed to 30 seconds, and "from 30 seconds to 60 seconds" is foaming. The number of times the foam B drips from 30 seconds after the injection of the body B to 60 seconds is shown. In each of Tables 4 to 7, "from 60 seconds to 120 seconds" is the number of times the foam B drips from 60 seconds after the injection of the foam B to 120 seconds, "120 seconds". "From to 180 seconds" indicates the number of times the foam B drips from 120 seconds after the injection of the foam B to 180 seconds. "Continuous" in Tables 4 to 7 means that the state in which the foam B hangs down is not a drop, but the state in which the foam B flows out in a linearly continuous manner from the time when the pouring of the foam B is completed. Indicates whether it occurred after a second. “2/60” in Table 5 indicates that the foam B was linearly continuous after 2 seconds and 60 seconds.

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). When the diameter of the air flow path 46f is 2.0 mm or more and 5.0 mm or less as shown in (Diameter 5.0 mm), 120 seconds have passed since the injection of the foam B was stopped. The number of back drips could be suppressed to one or less. Regarding the linear dripping (continuous) of the foam B that occurs after the pouring of the foam B is stopped, if the diameter of the air flow path 46f is large, the linear dripping of the foam B can be reduced. Do you get it. When the diameter of the air flow path 46f was 4.0 mm or more (Tables 6 and 7), the linear drooping of the foam B could be suppressed immediately after the foaming was stopped. Therefore, when the diameter of the air flow path 46f is 4.0 mm or more, the linear back dripping of the foam B can be suppressed, which is more preferable from the viewpoint of suppressing the back dripping.
