Description

The present invention relates to a carbonated beverage supply mechanism and a carbonated beverage supply system having a carbonated beverage supply unit and a cone.

Conventionally, a carbonated beverage dispenser that supplies carbonated water and supplies a carbonated beverage by mixing the beverage stock solution with the carbonated water has been known, and it has been proposed to use a cylindrical cone for the carbonated beverage dispenser ( Patent Document 1).

In recent years, highballs and the like have become popular, and there is an increasing need to supply carbonated beverages with a high carbon dioxide gas content. The amount of carbon dioxide contained in the carbonated water supplied to a container such as a glass is higher than the concentration when the carbon dioxide is dissolved in water, and the carbonated water is supplied to the glass from the carbonated water storage section where the carbonated water is stored. It is important how carbon dioxide does not escape in the route until it is done. In this respect, the configuration disclosed in Patent Document 1 is insufficient from the viewpoint of supplying a carbonated beverage having a high carbonic acid content.

First Embodiment << Configuration >>
Hereinafter, embodiments according to the present invention will be described with reference to the drawings. In the present embodiment, carbonated water will be used as the carbonated drink, but the present invention is not limited to this, and the present invention can be applied to carbonated drinks other than carbonated water.

As shown in FIGS. 1 and 2, the carbonated water supply mechanism of the present embodiment is provided in the main body 10 and the main body 10 to supply carbonated water directly to the carbonated water supply 20 and the main body 10. It may have a cone 30 attached to the target or indirectly. A carbonated water supply unit 20 may be provided above the main body unit 10. A main body recess 11 may be provided in the main body 10, and the cone 30 may be fitted into the main body recess 11 so that the cone 30 can be attached to the main body 10. The cone 30 may be made of a metal such as stainless steel, or may be made of a resin material.

The cone 30 may extend along the thickness direction (vertical direction in FIG. 1) and may have one or more through holes 39 through which carbonated water passes. The carbonated water supply unit 20 may be a carbonated water supply pipe through which carbonated water supplied from the carbonated water storage unit 110 (see FIG. 8) such as a carbonator passes through. The carbonated water supplied from the carbonated water supply unit 20 may be poured into a container such as a glass or a mug from a nozzle cap 60, which will be described later, via a cone 30. The through hole 39 may be formed by a mold, or may be drilled by machining. By adopting these aspects, it is possible to form a through hole 39 with little variation during mass production. The diameter of the through hole 39 is, for example, 0.3 mm to 1.2 mm, typically 0.8 mm to 1.0 mm. It is conceivable that the number of through holes 39 is 1 to 30 according to the flow rate at the time of pouring.

The through hole 39 may extend along the thickness direction of the cone 30. The phrase "extending along the thickness direction of the cone 30" includes not only a mode provided parallel to the thickness direction (vertical direction in FIG. 1) but also a mode provided inclined with respect to the thickness direction. (See FIG. 9 (a)). However, from the viewpoint of ease of processing, it is advantageous that the through hole 39 is provided in parallel with the thickness direction. The through holes 39 may be provided at equal intervals, that is, in such a manner that the circumferential angles between the through holes 39 are equal when the cone 30 is viewed from the front surface (upper surface) or the back surface (lower surface) (FIG. 7).

As shown in FIG. 1, the filter 90 may be provided so as to be placed on the cone 30. The filter 90 may be a mesh filter made of stainless steel. The number of mesh filters may be, for example, 10 to 200 meshes, typically 80 to 120 meshes. The mesh represents the number of meshes between 1 inch (25.4 mm). The mesh filter opening may be, for example, 0.05 mm to 1.0 mm, typically 0.1 mm to 0.3 mm. The alignment of the mesh filter may be, for example, 0.077 mm to 1.54 mm, typically 0.08 mm to 0.12 mm.

In FIG. 10, the filter 90 is provided on the front surface side (upper side) which is one side of the cone 30, but the present invention is not limited to this mode, and the filter 90 is provided on the other side of the cone 30. It may be provided on a certain back surface side (lower side). A washer 190 may be provided above the cone 30 and the filter 90. The washer 190 may be provided adjacent to the filter 90, but when the cone 30 is located on the front surface side (upper side) of the filter 90, the washer 190 may be provided adjacent to the cone 30. Good. An opening 91 for passing the first liquid supply unit 40, which will be described later, may be provided in the central portion of the filter 90. Similarly, an opening 191 for passing the first liquid supply unit 40 may be provided in the central portion of the washer 190.

As shown in FIG. 1, a first liquid supply unit 40 for supplying the first liquid may be provided. A part (downstream side portion) of the first liquid supply unit 40 may extend along the thickness direction of the cone 30 (in the vertical direction in the embodiment shown in FIG. 1). The first liquid supply unit 40 may be a first liquid supply pipe through which a beverage stock solution such as whiskey or syrup supplied from the first liquid storage unit 120 (see FIG. 8) passes through. In the present embodiment, the downstream portion of the first liquid supply unit 40 means a portion of the first liquid supply unit 40 extending in the vertical direction in FIG. 1.

As shown in FIG. 7, a circular opening 35a may be provided in the center of the cone member 35 described later of the cone 30. Then, as shown in FIG. 1, the downstream portion of the first liquid supply unit 40 may pass through the opening 35a, and the cone 30 may be arranged so as to surround the peripheral edge of the first liquid supply unit 40. A first seal member 51 such as an O-ring made of an elastic member may be provided between the inner peripheral surface of the cone 30 and the outer peripheral surface of the first liquid supply unit 40.

As shown in FIG. 5, the valves include a carbonated water supply valve 70 for controlling the supply of carbonated water, a first liquid supply valve 75 for controlling the supply of a first liquid such as a beverage stock solution, and carbonated water. It may have a lever 80 for controlling the opening and closing of the supply valve 70 and the first liquid supply valve 75. When the user presses the glass or the like against the lever 80, the carbonated water supply valve 70 and the first liquid supply valve 75 are opened, the carbonated water is supplied from the carbonated water supply unit 20, and the first liquid is the first. It may be supplied from the liquid supply unit 40 (see also FIG. 6).

As shown in FIGS. 1 and 2, an umbrella body 5 provided with a plurality of concentric grooves (not shown) may be provided on the lower side of the cone 30. Like the cone 30, the umbrella body 5 may be arranged so as to surround the outer peripheral surface of the downstream portion of the first liquid supply unit 40. The lower end portion of the first liquid supply portion 40 may be positioned below the lower end portion of the umbrella body 5.

As shown in FIGS. 2 and 3, a nozzle cap 60 that surrounds the outside of the cone 30 may be provided. The nozzle cap 60 has a shape in which an internal space is formed, and is provided on the outer peripheral surface of the downstream side portion of the first liquid supply unit 40 and the downstream side portion of the first liquid supply unit 40 in the internal space. The cone 30, the umbrella body 5, and the like will be positioned. Note that the filter 90 is not shown in FIG.

As shown in FIG. 1, a second seal member 52 such as an O-ring made of an elastic member may be provided between the inner peripheral surface of the main body 10 and the outer peripheral surface of the cone 30.

As shown in FIG. 9B, the cone 30 may be composed of a single member such as the cone member 35 described later. However, the present invention is not limited to this aspect, and the cone 30 may be composed of a plurality of members. For example, as shown in FIG. 4, the cone 30 may have an inner cone 31 and an outer cone 32 provided on the outer periphery of the inner cone 31. When such an aspect is adopted, the second seal member 52 may be provided between the inner peripheral surface of the main body 10 and the outer peripheral surface of the outer cone 32. Further, a third seal member 53 such as an O-ring made of an elastic member may be provided between the inner peripheral surface of the outer cone 32 and the outer peripheral surface of the inner cone 31. The thickness of the outer cone 32 is larger than the thickness of the inner cone 31, and the outer cone 32 surrounds the entire outer peripheral surface of the inner cone 31 and extends above the upper end of the inner cone 31. It may extend below the lower end.

As shown in FIG. 4, an inner peripheral recess 31a may be provided on the inner peripheral surface of the inner cone 31, and the first seal member 51 may be provided in the inner peripheral recess 31a. An outer peripheral recess 31b may be provided on the outer peripheral surface of the inner cone 31, and a third seal member 53 may be provided on the outer peripheral recess 31b. An outer peripheral recess 32a may be provided on the outer peripheral surface of the outer cone 32, and a second seal member 52 may be provided in the outer peripheral recess 32a. Note that the filter 90 is not shown in FIG.

In the present embodiment, the inner cone 31 is composed of one cone member 35. The number of through holes 39 provided in the cone member 35 may be adjusted according to the amount of carbonated water to be supplied, or may be determined in relation to the diameter (diameter) of the through holes 39. The number of through holes 39 may be, for example, 1 or more and 30 or less (see the second embodiment described later). The diameter of the through hole 39 may be, for example, about 0.3 mm to 1.2 mm. The surface of the cone member 35 may be unprocessed and may be composed of a flat surface (see FIG. 4). Even when such a flat surface is adopted, it should be noted that the flat surface has unavoidable irregularities.

As the thickness of the cone member 35, for example, one having a thickness of 2 mm to 7 mm can be adopted, and if more limited, one having a thickness of 3.5 mm to 5 mm can be adopted.

As shown in FIG. 10, the concave-convex shape 130 may be formed on the front surface (upper surface or one surface) and / or the back surface (lower surface or the other surface) of the cone member 35 (inner cone 31). The uneven shape 130 may employ a mode in which a plurality of grooves are provided on the front surface and / or the back surface of the cone member 35, or a spiral groove is provided. In the embodiment shown in FIG. 10, the concave-convex shape 130 has a straight concave portion 130a extending linearly from the center in the radial direction and an arc concave portion 130b extending in an arc shape between the straight concave portions 130a.

The uneven shape 130 may be provided only on the surface that comes into contact with the filter 90, and the uneven shape 130 may not be provided on the surface that does not come into contact with the filter 90. In the embodiment shown in FIG. 10, the concave-convex shape 130 may be provided only on the front surface (upper surface) of the cone member 35, and the concave-convex shape 130 may not be provided on the back surface (lower surface).

The inner cone 31 and the outer cone 32 may be made of the same material, but may be made of different materials. As an example, both the inner cone 31 and the outer cone 32 may be made of a metal such as stainless steel, both the inner cone 31 and the outer cone 32 may be made of a resin material, or the inner cone 31 may be made of a resin material. And one of the outer cones 32 may be made of a metal such as stainless steel and the other may be made of a resin material. It should be noted that the case where the resin material is used is less affected by heat such as the outside air than the case where the metal is used, and it is advantageous in that it can be expected to provide carbonated water having a stable carbonic acid content. On the other hand, it is more advantageous to use metal as a material in that it is easy to form a diameter of a small through hole.

As shown in FIG. 8, the carbonated water storage unit 110 may be connected to a pump 181 for applying a driving force to water and a cooling unit 182 for cooling water. A carbon dioxide cylinder 140 containing carbon dioxide may be connected to the carbonated water storage unit 110 via a check valve 116 provided in the carbonated water storage unit 110. The carbonated water storage unit 110 may be provided with a float switch 115 for measuring the amount of water in the carbonated water storage unit 110. Carbonated water may be stored in the carbonated water storage unit 110 at a temperature close to 0 ° C. The carbonated water content in the carbonated water storage unit 110 is determined by the pressure of the gas from the carbon dioxide cylinder 140 and the temperature of the carbonated water. Further, as shown in FIG. 8, a pump 186 for applying a driving force to the first liquid may be connected to the first liquid storage unit 120.

"effect"
Next, the effects of the present embodiment having the above-described configuration, which have not been described yet, will be mainly described.

In the present embodiment, when a cone 30 extending along the thickness direction and having a through hole 39 through which carbonated water passes and a filter 90 mounted on the cone 30 are adopted (see FIG. 10). It is possible to reduce gas loss and supply carbonated water (carbonated beverage) having a high carbon dioxide content.

In the dispenser that produces and dispenses carbonated water, the gas volume after pouring is one of the important parameters. In order to realize a high gas volume, it is important to (1) mix high-pressure carbon dioxide gas and cooled water in the carbonator in the dispenser, and (2) reduce the gas loss at the time of pouring. Regarding (1), the pressure inside the carbonator must be 1 Mpa or less due to the regulation of high pressure gas. Therefore, in the past, in order to realize a high pressure gas, a high pressure gas having a value slightly lower than 1 MPa (for example, 0.95 MPa) was used to realize a high gas volume, but such a high pressure gas is used. For that purpose, it is necessary to introduce an expensive machine (carbonator). On the other hand, according to the present embodiment, even when a machine that supplies a gas pressure of, for example, 0.6 MPa to 0.7 MPa is used without introducing such an expensive machine, a high gas volume can be obtained. An extremely excellent effect can be obtained in terms of realization.

A mode in which a plurality of grooves are provided on the surface of the cone 30 or a spiral groove is provided may be adopted, and the uneven shape 130 may be formed on the surface of the cone 30 by such grooves (FIG. 10). reference). The inventors of the present application have confirmed that a high gas volume can be realized when the concave-convex shape 130 is provided on the surface of the cone 30 and the concave-convex shape 130 and the filter 90 are brought into contact with each other.

It is conceivable to reduce gas loss by using a decompression component or the like provided with knurled fine grooves without providing the through hole 39, but in the structure, the gas loss reduction effect depends on the component accuracy. In addition, it becomes an expensive part due to the demand for accuracy. It is also difficult to adjust the flow rate and gas volume by appropriately changing the shape. On the other hand, in the embodiment of the present embodiment, the gas loss reduction effect can be realized at low cost, and the flow rate and the gas volume can be adjusted by an easy method of changing the number and size of the through holes 39. Further, as shown in the second embodiment described later, the flow rate and the gas volume can also be adjusted by changing the number of the cone member 35 and the filter 90.

When a mode in which a plurality of through holes 39 are provided is adopted, the diameter of the through holes 39 can be reduced even if the amount of carbonated water supplied is the same. Therefore, it can be expected that the impact applied to the carbonated water passing through the through hole 39 can be suppressed, and that the carbonated water having a higher carbon dioxide gas content can be supplied. The amount of carbonated water supplied per unit time is set within a generally fixed range because it affects the serving time of beverages in stores such as pubs and restaurants. For example, a value of 30 cc / sec is set. ing. Therefore, if the number of through holes 39 is increased on the premise that the amount of carbonated water supplied per unit time is within a predetermined range, the diameter of the through holes 39 can be reduced accordingly.

An embodiment is adopted in which a first seal member 51 made of, for example, an elastic member is provided between the inner peripheral surface of the cone 30 and the outer peripheral surface of the downstream portion of the first liquid supply part 40 made of the first liquid supply pipe or the like. In some cases (see FIG. 1), it is possible to prevent carbonated water from passing between the cone 30 and the first liquid supply unit 40. Therefore, it is possible to prevent carbonated water from being poured from the nozzle cap 60 into a container such as a glass or a mug without passing through the through hole 39 of the cone 30.

When a mode in which a second seal member 52 made of, for example, an elastic member, is provided between the inner peripheral surface of the main body 10 and the outer peripheral surface of the cone 30, for example, the main body recess 11 of the main body 10 and the cone 30 It is possible to prevent carbonated water from passing between the spaces. Therefore, even in this case, it is possible to prevent carbonated water from being poured from the nozzle cap 60 into a container such as a glass or a mug without passing through the through hole 39 of the cone 30.

In the case where the cone 30 has the inner cone 31 and the outer cone 32, when the embodiment in which the third sealing member 53 is provided between the inner peripheral surface of the outer cone 32 and the outer peripheral surface of the inner cone 31 is adopted, Even when two members such as the inner cone 31 and the outer cone 32 are adopted, it is possible to prevent carbonated water from passing between the inner cone 31 and the outer cone 32. Therefore, while adopting two members, the inner cone 31 and the outer cone 32, carbonated water is poured from the nozzle cap 60 into a container such as a glass or a mug without passing through the through hole 39 of the cone 30. Can be prevented.

By adopting an embodiment in which the cone 30 has an inner cone 31 and an outer cone 32, the influence of component variations including manufacturing tolerances of the main body 10 is reduced, and the cone 30 is attached to the main body recess 11 of the main body 10. It is beneficial in that it can be done. More specifically, it is inevitable that a manufacturing tolerance will occur when manufacturing the main body 10. In particular, in the main body 10, since a large number of parts are combined, tolerance deviations may be gathered to increase the manufacturing tolerance. In this regard, by adopting the outer cone 32 and the second seal member 52 provided on the outer peripheral surfaces of the outer cone 32, the influence of the component variation of the main body 10 can be absorbed by the second seal member 52. Further, the distance between the outer cone 32 and the inner cone 31 can also be adjusted by the third seal member 53 provided between the outer cone 32 and the inner cone 31. From these facts, it is possible to make it less likely to be affected by the variation of parts including the manufacturing tolerance of the main body 10, and it is advantageous in that it becomes possible to supply carbonated water having a higher carbon dioxide gas content. In the embodiment in which the carbonated water passes through the outer peripheral surface of the cone as in Patent Document 1 without having the through hole 39 as in the present embodiment, due to the influence of component variations including the manufacturing tolerance of the main body 10, It cannot be denied that the carbon dioxide content of the carbonated water provided may also change. Therefore, in such an embodiment, the carbon dioxide gas content of the provided carbonated water may not be uniform, but in the present embodiment, it is advantageous in that such a problem is unlikely to occur.

Second Embodiment Next, a second embodiment of the present invention will be described.

In the present embodiment, as shown in FIGS. 11 and 12, the inner cone 31 has a plurality of cone members 35 laminated in the thickness direction (vertical direction), and each of the cone members 35 has a through hole 39. Will be described with reference to the embodiment having the above. In the present embodiment, any configuration adopted in the first embodiment can be adopted. The members described in the first embodiment will be described with the same reference numerals.

As shown in FIGS. 11 (a) and 12 (a), an embodiment having a rectangular cross section may be adopted, but as shown in FIGS. 11 (b) and 12 (b), the cone member 35 A protrusion 35b is provided on the peripheral edge of the cone member 35b, and a gap may be provided between the cone member 35 and the filter 90 by the protrusion 35b (see also FIG. 7).

By increasing the length of the through hole 39, the resistance to carbonated water can be increased, and the carbonated water can flow slowly. However, when the thickness of the cone member 35 becomes thick, it becomes difficult to form the through hole 39 by injection molding or cutting, and a problem of dimensional stability tends to occur. In particular, when the cone member 35 is made of a resin material and the diameter of the through hole 39 is small, it becomes difficult to process the through hole 39. In this respect, by adopting a plurality of cone members 35 to be laminated as in the present embodiment, the length of the through hole 39 is made to be a predetermined value or more while suppressing the difficulty in forming the through hole 39. It is beneficial in that it can be done.

Further, in the case of adopting the embodiment having a plurality of cone members 35 in this way, the filter 90 may be provided between the cone members 35. In this case, the filter 90 may be provided between the plurality of cone members 35 so as to be in contact with each cone member 35. Further, the filter 90 may be provided above the cone member 35 located at the uppermost position, or the filter 90 may be provided below the cone member 35 located at the lowermost position.

Further, when the outer cone 32 is adopted and the inner cone 31 provided in the outer cone 32 has a plurality of cone members 35, the plurality of cone members 35 are fitted into the outer cone 32. , It is advantageous in that the positional relationship of each cone member 35 can be positioned more accurately.

Two cone members 35 may be provided, three may be provided, or four or more may be provided. Each cone member 35 may be a member having the same thickness or material, or may be a member having a different thickness or material. For example, of the plurality of cone members 35, one or more cone members 35 may be formed of a resin material, and the remaining cone members 35 may be formed of metal.

In the embodiment in which two cone members 35 are provided as shown in FIG. 11, as an example, when the thickness of the cone member 35 is 3.5 mm, 11 through holes 39 having a diameter of 0.5 mm may be provided. Alternatively, six through holes 39 having a diameter of 0.7 mm may be provided, or four through holes 39 having a diameter of 0.9 mm may be provided. Further, in the embodiment in which three cone members 35 are provided as shown in FIG. 12, 14 through holes 39 having a diameter of 0.5 mm may be provided when the thickness of the cone member 35 is 3.5 mm. However, eight through holes 39 having a diameter of 0.7 mm may be provided, or five through holes 39 having a diameter of 0.9 mm may be provided.

11 and 12 have been described using an aspect in which the positions of the through holes 39 in the in-plane direction are completely matched, but the present invention is not limited to this, and as shown in FIG. 13, the through holes 39 are used. The positions of the above in the in-plane direction may be in such a manner that they partially match. By partially matching the positions of the through holes 39 in the in-plane direction in this way, it is advantageous in that it can be expected to obtain the same effect as when the diameter of the through holes 39 is substantially reduced.

As described above, in the present embodiment, any configuration adopted in the first embodiment can be adopted. Therefore, for example, the cone 30 may not be composed of two types of members, the inner cone 31 and the outer cone 32, but the cone 30 may be composed of only the cone member 35 as shown in FIG. Further, also in this aspect, an aspect in which the thicknesses and the like of the laminated cone members 35 are different from each other may be adopted.

As shown in FIGS. 15 to 18, even if the through hole 39 of a certain cone member 35 and the through hole 39 of another cone member 35 laminated on the certain cone member 35 are arranged so as to be displaced in the plane direction. Good. The "plane direction" of the present embodiment means an in-plane direction (direction in the paper surface of FIG. 19 described later) orthogonal to the thickness direction of the cone member 35.

Although a certain cone member 35 and another cone member 35 are the same member, the through hole 39 may be displaced in the plane direction by arranging them at positions shifted along the circumferential direction. In this case, as shown in FIG. 19A, one or a plurality of positioning recesses 132 on the inner peripheral surface of the outer cone 32 are used to position the positions of the cone members 35 along the circumferential direction. Is provided, and one or a plurality of positioning protrusions 131 that fit with the positioning recess 132 may be provided on the outer peripheral surface of the inner cone 31. In addition, in the aspect shown in FIG. 19A, an aspect in which one positioning concave portion 132 and one positioning convex portion 131 are provided is shown.

Further, as shown in FIG. 19B, one or a plurality of positioning convex portions 137 are provided on the inner peripheral surface of the outer cone 32, and one that fits with the positioning convex portion 137 on the outer peripheral surface of the inner cone 31. Alternatively, a plurality of positioning recesses 136 may be provided. In the aspect shown in FIG. 19B, one positioning convex portion 137 and one positioning concave portion 136 are provided.

Further, as a mode in which the through hole 39 is displaced in the plane direction, for example, as shown in FIGS. 20 and 21, the radius where the through hole 39 of the certain cone member 35 is located and the thickness direction (vertical direction) of the certain cone member. ), A mode in which the radius of the through hole 39 of the other adjacent cone member 35 is different from the radius may be used. In addition, in the embodiment shown in FIGS. 20 and 21, the protrusion 35b as described above may be provided.

As in the present embodiment, the through holes 39 of the other cone member 35 laminated with respect to the certain cone member 35 and the certain cone member 35 via the filter 90 are arranged so as to be offset in the plane direction. By doing so, it can be expected that carbonated water slowly flows through the gap in the plane direction between one cone member 35 and another cone member 35. Therefore, it can be expected to prevent carbon dioxide gas from escaping from the carbonated water while adjusting the flow rate per unit time.

Three or more cone members 35 may be provided. In the embodiment in which three or more cone members 35 are provided, as shown in FIGS. 17, 18 and 21, the through holes 39 of the cone members 35 are displaced in the plane direction in the two adjacent cone members 35 via the filter 90. In the two cone members 35 that are not adjacent to each other via the filter 90, the positions of the through holes 39 may be matched in the plane direction (the positions of the through holes 39 may be matched when viewed from above). As an example, when the embodiment in which three cone members 35 are provided is adopted, the through holes 39 in the cone members 35 located at the upper and lower portions are positioned at positions that match when viewed in the plane direction. The through hole 39 of the cone member 35 located between the upper and lower cone members 35 may be displaced in the plane direction from the through hole 39 of the upper and lower cone members 35. When such an embodiment is adopted, carbonated water can be slowly flowed by utilizing the space between the cone members 35. An embodiment in which the radius at which the through hole 39 of a certain cone member 35 is located and the radius at which the through hole 39 of another cone member 35 adjacent to the certain cone member via the filter 90 is located are different in size. By adopting the same member as the cone member 35 located at the upper part and the lower part as shown in FIG. 21, the types of the cone member 35 to be used can be reduced (two types can be used). ) It is beneficial in that respect.

However, the present invention is not limited to such an aspect, and the through holes 39 of each cone member 35 may be displaced in the plane direction when viewed from above.

In the embodiment in which four or more cone members 35 are provided, the through holes 39 of the cone members 35 are displaced in the plane direction in at least one set consisting of two adjacent cone members 35 via the filter 90, but the through holes 39 are displaced in the plane direction through the filter 90. In another set of two adjacent cone members 35, the through holes 39 of the cone members 35 may be aligned in the plane direction (see FIG. 22).

As shown in FIG. 23, the number of through holes 39 of a certain cone member 35 and the number of through holes 39 of another cone member 35 laminated on the certain cone member 35 may be different. In FIG. 23 (a), as an example, eight through holes 39 are arranged at equal intervals, and in FIG. 23 (b), seven through holes 39 are arranged at equal intervals. The cone member 35 shown in (a) and the cone member 35 shown in FIG. 23 (b) are laminated adjacent to each other in the vertical direction. The embodiment shown in FIG. 23 is merely an example. For example, an embodiment in which three cone members 35 are provided is adopted, and the cone members 35 located at the upper and lower portions have a predetermined number of through holes (for example, 14). In the cone member 35 provided and provided between the cone members 35, a number (for example, 13) of through holes different from the predetermined number may be provided. The difference between the number of through holes 39 of a certain cone member 35 and the number of through holes 39 of another cone member 35 laminated on a certain cone member 35 may be "1". The difference may be "2" or more.

When the number of through holes 39 of a certain cone member 35 and the number of through holes 39 of another cone member 35 laminated on a certain cone member 35 are different as in this embodiment, for example, carbonated water The number of through holes 39 can be adjusted according to the ease of flow. Further, since the number of through holes 39 is different, the through holes 39 of one cone member 35 and the through holes 39 of another cone member 35 are likely to be displaced in the plane direction. For example, when the through holes 39 are provided at equal intervals (a mode in which the inscribed angles between the through holes 39 are equal), even if one through hole 39 matches in the plane direction, other through holes 39 may be provided. The through hole 39 is displaced between the adjacent cone members 35 via the filter 90. Therefore, by providing the cone member 35 without worrying about the position of the cone member 35 in the circumferential direction, the position in the surface direction can be inevitably shifted in the other through holes 39.

Also in this embodiment, three or more cone members 35 may be provided. In the embodiment in which three or more cone members 35 are provided, the number of through holes 39 is different between the two adjacent cone members 35 via the filter 90, and the through holes 39 of the cone members 35 that are not adjacent to each other via the filter 90. The numbers may be the same. As an example, when three cone members 35 are provided, the number of through holes 39 in the upper and lower cone members 35 is the same, and the number of through holes 39 is the same between the upper and lower cone members 35. The number of through holes 39 of the positioned cone member 35 may be different from the number of through holes 39 of the upper and lower cone members 35.

Further, in the embodiment in which four or more cone members 35 are provided, the number of through holes 39 of the cone member 35 is different in at least one set consisting of two adjacent cone members 35 via the filter 90, but the filter 90 is used. The number of through holes 39 of the cone member 35 may match in another set of two cone members 35 adjacent to each other.

(Example)
As an example, the results of experiments conducted by the inventor using the aspects shown in FIGS. 24 and 25 are shown in Table 1 below. In the embodiment shown in FIGS. 24 and 25, three cone members 35 and two filters 90 provided between the cone members 35 are provided. Concavo-convex shapes 130 are provided on each of the front surface and the back surface of the cone member 35, and the concave-convex shape 130 is formed between a straight concave portion 130a extending linearly from the center in the radial direction and a straight concave portion 130a. It has an arc recess 130b extending in an arc shape (see FIG. 10). The cone member 35 is provided with eight through holes 39 at equal intervals (same inscribed angle), and the through holes 39 adjacent in the plane direction are arranged at different angles by 45 degrees. The positions of the through hole 39 of the cone member 35 located at the uppermost position and the through hole 39 of the cone member 35 located at the lowermost position match in a plan view (when viewed from above), but at the uppermost position. The positions of the through hole 39 of the cone member 35 located, the through hole 39 of the cone member 35 located at the lowermost position, and the through hole 39 of the cone member 35 located in the center are approximately (when viewed from above). They are arranged with a deviation of 22.5 degrees.

For the gas volume shown in Table 1 below, a gas pressure of 0.7 MPa was supplied from a carbonator, and the gas volume contained in the carbonated water after being poured into a glass was measured using T-03-567 manufactured by TERRISS. It is a thing.

On another occasion, the results of measurement under the same conditions as above are shown in Table 2 below.

As described above, the amount of carbonated water supplied per unit time is set to a value such as 30 cc / sec. Generally, the faster the flow rate, the easier it is for the carbon dioxide contained in the carbonated water to escape, but even at a high speed of 36 cc / sec, the average gas volume of the carbonated water is 5.90 to 5.98, which is extremely high. What was done is very amazing. In order to increase the gas volume of carbonated water to nearly 6, a high-priced carbonator was generally adopted, and a high gas volume was realized by using a high-pressure gas (for example, 0.95 MPa) with a value slightly lower than 1 MPa. From this, it is very surprising that the gas volume was increased to nearly 6 when the gas pressure of 0.7 MPa was supplied from the carbonator. By increasing the gas volume of carbonated water to nearly 6 with a gas pressure of 0.7 MPa in this way, the introduction cost can be significantly reduced, which is extremely beneficial.

For reference, the measurement results using the same embodiment as in the above embodiment except that the two filters 90 are not provided and the flow rate is reduced to 34 cc / sec are shown in Tables 3 and 4 below. In this case, it can be confirmed that the gas volume of carbonated water is about 5.

From this result as well, it is possible to confirm the extremely excellent effect of providing the filter 90. By the way, it has been confirmed that an excellent effect on gas volume can be obtained by Japanese Patent Application No. 2018-001717 filed by one of the applicants, but it has been confirmed that the present application can realize a more excellent effect. Is.

The outer cone 32 shown in FIGS. 24 and 25 has a structure different from that of the first embodiment and the second embodiment, and is an upstream end portion (one side end portion) in the flow of carbonated water. It has an inwardly projecting portion 32d and an expansion portion 32c extending in the radial direction at the downstream end portion (the other side end portion). By providing the inwardly projecting portion 32d, the member located on the uppermost side (washer 190 in FIG. 25) can be pressed against the member located on the lower side (cone member 35 in FIG. 25). Further, by using the expansion portion 32c, the cone member 35 can be easily attached to and detached from the outer cone 32.

Third Embodiment Next, a third embodiment of the present invention will be described.

In this embodiment, as shown in FIGS. 26 and 27, the first carbonated water supply mechanism 200 and the second carbonated water supply mechanism 300 are provided. The first carbonated water supply mechanism 200 is provided in the main body portion 10 and has a first carbonated water supply portion 220 for supplying carbonated water and a first cone 230 attached to the main body portion 10. The second carbonated water supply mechanism 300 is provided in the main body portion 10 and has a second carbonated water supply portion 320 for supplying carbonated water and a second cone 330 attached to the main body portion 10. In FIG. 26, the main body 10 of the first carbonated water supply mechanism 200 and the main body 10 of the second carbonated water supply mechanism 300 will be described using the same member, but the present invention is not limited to this. The main body of the first carbonated water supply mechanism 200 and the main body of the second carbonated water supply mechanism 300 may be provided separately and may be separate members. Also in this embodiment, any configuration adopted in each of the above embodiments can be adopted. The members described in each of the above embodiments will be described with the same reference numerals. In the present embodiment, the embodiment having two carbonated water supply mechanisms of the first carbonated water supply mechanism 200 and the second carbonated water supply mechanism 300 will be described, but the present invention is not limited to this, and three of them are used. An embodiment having the above carbonated water supply mechanism can also be used.

The first cone 230 and the second cone 330 have different configurations. As an example, as the first cone 230, a cone as described in the first embodiment and the second embodiment may be used, and as the second cone 330, a conventionally known known cone may be used. Good (see Figure 26). When such an embodiment is used, the first carbonated water supply mechanism 200 can supply carbonated water having a high carbon dioxide gas content, and the second carbonated water supply mechanism 300 is compared with the first carbonated water supply mechanism 200. It is possible to supply carbonated water with a low carbon dioxide content. Therefore, it is advantageous in that the carbon dioxide gas content can be changed according to the beverage to be provided.

As another example, as the first cone 230, a cone of any of the embodiments described in the first embodiment and the second embodiment is used, and the second cone 330 is adopted in the first cone 230. You may use a cone different from the one shown (see FIG. 27). Even if such an embodiment is used, it is advantageous in that carbonated water having different carbon dioxide gas contents can be supplied. In FIG. 27, as an example, as the first cone 230, the inner cone 31 has two cone members 35, a filter 90 is provided between the two cone members 35, and the through hole 39 is in the plane direction. It shows an aspect in which they are arranged in a staggered manner. As the second cone 330, the inner cone 31 has three cone members 35, and a filter 90 is provided between each of the two adjacent cone members 35. It shows an embodiment in which the through holes 39 are arranged so as to be offset in the plane direction.

As yet another example, carbonated water having different carbon dioxide gas contents can be obtained by making the diameter and number of through holes 39 in the first cone 230 different from the diameter and number of through holes 39 in the second cone 330. It may be possible to supply.
