Description

The present invention relates to a liquid-solid partition member and a carbonated water production apparatus.

In order to produce carbonated water at home or the like, a carbonated water production apparatus that does not use a carbon dioxide gas cylinder has been proposed (see Patent Document 1). In the apparatus described in Patent Document 1, the carbon dioxide gas generating container, the trap, and the carbonated water production container are airtightly connected, and the device is generated by the reaction of sodium hydrogen carbonate with citric acid and water in the carbonated water generating container. Carbonated water is produced by pressurizing and dissolving it in drinking water in a carbonated water production container after removing splashes of the reaction solution by a trap using the gas pressure generated during the reaction. .. Sodium hydrogen carbonate and citric acid are in powder form and are quantitatively packaged with wrapping paper. The purpose of using wrapping paper is to prevent carbon dioxide gas loss before and after water injection before sealing. The wrapping paper is made of a water-soluble material, and does not dissolve before and after water injection, but dissolves immediately after stirring with a closed stopper. In addition, a safety valve is used so that the pressure of the carbon dioxide gas generating container is controlled to a certain value or less.

Japanese Unexamined Patent Publication No. 2014-734666

By the way, when a water-soluble wrapping paper is used as in Patent Document 1, there is a problem that the dissolved state of the wrapping paper changes depending on the water temperature. When the water temperature is relatively high, the dissolution rate of the wrapping paper increases, so that the reaction starts before the sealing, which causes a loss of carbon dioxide gas. On the other hand, when the water temperature is relatively low, the wrapping paper becomes difficult to dissolve and the reaction does not start even after shaking.

The present invention has been made in view of the above circumstances, and an object of the present invention is a liquid-solid partition member and a partition member that are not affected by water temperature and can start a stable reaction after sealing. The present invention is to provide a carbonated water production apparatus having the above.

It is made smaller in the radial direction than the opening, the partition is moved from the outside to the inside of the container through the opening, the force from the outside is released, and the partition is restored to the original shape inside the container. The tubular portion of the partition is brought into contact with the inner peripheral surface of the container, the liquid is filled into the bottom side of the container through the opening of the container and the selective passage portion of the partition, and the powder is filled in the container. Filling the selective passage portion of the partition in the container through the opening of the container, and from a state in which the liquid and the powder are separated, the liquid is passed from the bottom side of the container to the powder side through the selective passage portion. A gas generation method is provided in which a gas is generated by moving the liquid and reacting the powder with the liquid.

As shown in FIG. 1, the carbonated water production apparatus 1 airtightly connects the first pipe portion 10 and the second pipe portion 20, which have airtightness, and the first pipe portion 10 and the second pipe portion 20, respectively. The connection piping unit 30 and the communication piping unit 40 that communicates the first piping unit 10 with the outside of the device are provided. The first piping section 10 is configured to be freely connectable to the first container 50 (see FIG. 6) for generating carbon dioxide gas, and the second piping section 20 is a second container 60 for dissolving carbon dioxide gas in water (FIG. 6). 6) and can be freely connected.

FIG. 2 is an exploded perspective view of the carbonated water production apparatus. When assembling each component shown in FIG. 2, the screwed portion of each component is filled with a sealing material such as sealing tape to maintain airtightness.

As shown in FIG. 2, the first piping portion 10 has a piping portion main body 11 extending in a first direction and a second direction orthogonal to the first direction and formed in a substantially cross shape. Here, the first direction will be described as the left-right direction, and the second direction will be described as the vertical direction. The piping portion main body 11 is integrally molded with resin, for example, and has a first pipe portion 11a extending to the left, a second pipe portion 11b extending to the right, and a third pipe portion 11c extending downward, and upward. It has a fourth pipe portion 11d that extends. The first pipe portion 11a, the second pipe portion 11b, the third pipe portion 11c, and the fourth pipe portion 11d are formed with substantially the same diameter at the proximal end side, and are connected to each other at the proximal end portion.

A diameter-expanded portion 11a1 is formed on the left end side of the first pipe portion 11a, and a female screw portion is formed on the inner peripheral surface of the diameter-expanded portion 11a1. A male screw portion is formed on the outer peripheral surface on the right end side of the second pipe portion 11b, and a female screw portion is formed on the inner peripheral surface on the right end side of the second pipe portion 11b. A male screw portion is formed on the outer peripheral surface of the third pipe portion 11c on the lower end side. A diameter-expanded portion 11d1 is formed on the end side of the fourth pipe portion 11d, and a female screw portion is formed on the inner circumference of the diameter-expanded portion 11d1.

A male threaded portion of the connection piping portion 30, which will be described later, is screwed into the female threaded portion of the first pipe portion 11a. The male threaded portion of the release valve 12 is screwed into the female threaded portion of the second pipe portion 11b. The female threaded portion of the cover 13 that covers the release valve 12 from the outside is screwed into the male threaded portion of the second pipe portion 11b. The female threaded portion of the connection cap 14 is screwed into the male threaded portion of the third pipe portion 11c. The male threaded portion of the communicating pipe portion 40 is screwed into the female threaded portion of the fourth pipe portion 11d.

FIG. 3 is a cross-sectional view of the release valve and the cover when the pressure in the first piping section is within a predetermined value, and FIG. 4 is a cross-sectional view of the release valve and the cover when the pressure in the first piping section exceeds a predetermined value. Is.
The open valve 12 is a valve for discharging the internal fluid to the outside of the apparatus when the pressure in the first piping portion 10 exceeds a predetermined value. As shown in FIG. 3, the release valve 12 includes a substantially cylindrical housing 12a whose left end side is connected to the first piping portion 10 and extends to the left and right, a rod 12b and a spring 12c arranged in the housing 12a, and a housing. It has a lid 12d that closes an end portion of the body 12a opposite to the first piping portion 10.

The housing 12a is made of, for example, resin, and a male screw portion to be screwed with the second pipe portion 11b is formed on the outer peripheral surface on the left end side. Further, a hole 12a1 through which a fluid can flow is formed on the central side of the housing 12a in the longitudinal direction. A convex portion 12a2 that comes into contact with the left end side of the rod 12b is formed on the inner peripheral surface of the housing 12a. Further, a female screw portion is formed on the inner peripheral surface on the right end side of the housing 12a.

The rod 12b is made of, for example, resin, and is arranged coaxially with the housing 12a. The rod 12b is provided with a substantially disk-shaped contact portion 12b1 formed at the left end and projecting outward in the radial direction, and an elastic body 12b2 on the left end surface of the contact portion 12b1. The elastic body 12b2 is made of, for example, silica gel, and in a state where the rod 12b is moved to the left end side, the elastic body 12b2 comes into contact with the corner portion of the convex portion 12a2 of the housing 12a. As a result, the airtightness inside the first piping portion 10 is maintained.

The lid 12d has a disk-shaped lid main body and a cylindrical portion extending to the left from the outer edge side of the lid main body, and a male screw portion is formed on the outer peripheral surface of the cylindrical portion. The male threaded portion of the cylindrical portion of the lid 12d is screwed with the female threaded portion on the inner peripheral surface of the housing 12a. Further, an insertion hole through which the rod 12b is inserted is formed in the center of the lid body.

The spring 12c is formed in a coil shape that winds around the main body of the rod 12b, and is interposed between the contact portion 12b1 of the rod 12b and the lid 12d. Since the spring 12c is set to contract more than the natural length and the lid 12d is screwed and fixed to the housing 12a, the rod 12b is constantly subjected to a urging force to the left from the spring 12c.

When the pressure in the first piping portion 10 is within a predetermined value, the force applied to the rod 12b from the fluid in the first piping portion 10 is less than the urging force of the spring 12c, so that the airtight state of the release valve 12 is maintained. As shown in FIG. 4, when the pressure in the first piping portion 10 exceeds a predetermined value, the force applied to the rod 12b from the fluid in the first piping portion 10 exceeds the urging force of the spring 12c, and the rod 12b moves to the right. The fluid in the first piping portion 10 flows out to the outside through the hole 12a1 of the housing 12a.

The cover 13 is made of, for example, resin, and is formed in a cylindrical shape with the right end closed. A diameter-expanded portion 13a is formed on the left end side of the cover 13, and a female screw portion is formed on the inner circumference of the diameter-expanded portion 13a. The female threaded portion of the cover 13 is screwed with the male threaded portion of the second pipe portion 11b of the first piping portion 11. The cover 13 is arranged at a predetermined distance from the release valve 12.

Further, the cover 13 has a plurality of pores 13b that allow the flow of gas and hinder the flow of liquid. In each hole 13b, the resistance force due to pipe friction when flowing through the hole 13b is set so that the liquid is significantly larger than the gas. Specifically, the smaller the diameter of each hole 13b and the larger the flow velocity of the fluid, the larger the resistance force, and this resistance force can be set according to the radial and axial dimensions of each hole 13b. can. As a result, even if the gas and the liquid flow out from the release valve 12 to the inside of the cover 13, the liquid does not flow out to the outside of the cover 13. It can be said that this solves the problem that the liquid inside the device is ejected together with the gas when the pressure is released by the safety valve, as in the technique described in Patent Document 1. For example, when the liquid is water and the gas is air, the pipe friction loss on the water is about 100 times that of air when the flow velocity is 10 m / s, and about 194 times when the flow velocity is 15 m / s. Can be set.

The connection cap 14 is made of, for example, a resin and has a base end portion 14a having a relatively small diameter and a container connecting portion 14b having a diameter larger than that of the base end portion 14a. A female threaded portion is formed on the inner peripheral surface of the base end portion 14a, and this female threaded portion is screwed with the male threaded portion of the third pipe portion 11c of the first piping portion 11. Further, a female threaded portion is formed on the inner peripheral surface of the container connecting portion 14b, and this female threaded portion is screwed with the male threaded portion of the first container 50.

As shown in FIG. 2, the second piping portion 20 has a substantially T-shaped piping portion main body 21 extending in the left-right direction and extending downward from the center of the left and right. The piping portion main body 21 has, for example, a first pipe portion 21a integrally formed of resin and extending to the right, a second pipe portion 21b extending to the left, and a third pipe portion 21c extending downward. Further, the piping portion main body 21 has a fourth pipe portion 21d extending forward from the meeting portion of the first pipe portion 21a, the second pipe portion 21b, and the third pipe portion 21c. The first pipe portion 21a, the second pipe portion 21b, the third pipe portion 21c, and the fourth pipe portion 11d are formed with substantially the same diameter at the proximal end side, and are connected to each other at the proximal end portion.

A diameter-expanded portion 21a1 is formed on the right end side of the first pipe portion 21a, and a female screw portion is formed on the inner circumference of the diameter-expanded portion 21a1. A male screw portion is formed on the outer peripheral surface of the second pipe portion 21b on the left end side, and a female screw portion is formed on the inner peripheral surface of the second pipe portion 21b on the left end side. A male screw portion is formed on the outer peripheral surface of the third pipe portion 21c on the lower end side. A male screw portion is formed on the outer peripheral surface of the fourth pipe portion 21d on the front end side.

A male threaded portion of the connection piping portion 30, which will be described later, is screwed into the female threaded portion of the first pipe portion 21a. The male threaded portion of the release valve 12 is screwed into the female threaded portion of the second pipe portion 21b. The female threaded portion of the cover 13 covering the release valve 12 is screwed into the male threaded portion of the second pipe portion 21b. The female threaded portion of the connection cap 14 is screwed into the male threaded portion of the third pipe portion 11c. The female threaded portion of the pressure gauge 25 is screwed into the female threaded portion of the fourth pipe portion 11d.

The open valve 12 of the second piping section 20 is a valve for letting the fluid inside escape to the outside when the pressure inside the second piping section 20 exceeds a predetermined pressure. In the present embodiment, the open valve 12 and the cover 13 of the second piping portion 20 are the same as the open valve 12 and the cover 13 of the first piping portion 10 arranged upside down. Further, the connection cap 14 of the second piping portion 20 is the same as the cap of the first piping portion 10, and the female threaded portion of the container connecting portion 14b is screwed with the male threaded portion of the second container 60.

The pressure gauge 25 has a pipe portion extending in the front-rear direction in which a male screw portion is formed on the outer peripheral surface, and displays the pressure in the pipe portion on a display portion provided at the front end of the pipe portion. On the outer peripheral surface on the rear end side of the pipe portion, a male screw portion that is screwed with the female screw portion of the fourth pipe portion 21d of the second piping portion 20 is formed. That is, the pressure gauge 25 displays the pressure in the second piping portion 20.

The connecting piping portion 30 has, for example, a piping portion main body 31 formed of resin and extending in the left-right direction. The right end side of the piping portion main body 31 forms the first pipe portion 31a, and a male screw portion screwing with the first pipe portion 11a of the first piping portion 10 is formed on the outer peripheral surface of the first pipe portion 31a. Further, the left end side of the piping portion main body 31 forms the second pipe portion 31b, and a male screw portion screwing with the first pipe portion 21a of the second piping portion 20 is formed on the outer peripheral surface of the second pipe portion 31b.

Further, the connection piping portion 30 has an on-off valve 32 provided in the center of the piping portion main body 31 to open and close the flow path. The on-off valve 32 can be manually operated by the operation lever. In the present embodiment, the open / closed state of the on-off valve 32 can be operated by rotating the operating lever extending in a predetermined direction about a rotation axis orthogonal to the piping portion main body 31. In the present embodiment, the on-off valve 32 is in an open state when the operating lever is in a state parallel to the piping section main body 31, and is in a closed state when the operating lever is in a state orthogonal to the piping section main body 31.

The communication piping unit 40 has, for example, a piping unit main body 41 that is formed of resin and extends in the vertical direction. The lower end side of the piping portion main body 41 forms the first pipe portion 41a, and a male screw portion screwing with the fourth pipe portion 11d of the first piping portion 10 is formed on the outer peripheral surface of the first pipe portion 41a. Further, the upper end side of the piping portion main body 41 forms the second pipe portion 41b, and a male screw portion to be screwed with the terminal cap 15 is formed on the outer peripheral surface of the second pipe portion 41b.

FIG. 6 is a front view of a carbonated water production apparatus showing a state in which the first container and the second container are connected.
As shown in FIG. 6, in producing carbonated water by the carbonated water production apparatus 1, the first container 50 and the second container 60 are used. Each of the first container 50 and the second container 60 is made of, for example, a transparent resin, has a tubular shape with the lower end closed and the upper side narrowed, and has an opening at the upper end. As the first container 50 and the second container 60, for example, an empty bottle of a commercially available PET bottle beverage can be used.

FIG. 5A is an external perspective view of the partition.
The carbonated water production apparatus 1 has a partition 70 arranged in the first container 50. As shown in FIG. 5A, the partition 70 has a tubular portion 71 extending in the vertical direction and a selective passing portion 72 that closes the upper end of the tubular portion 71. As shown in FIG. 6, the tubular portion 71 comes into contact with the inner peripheral surface of the first container 50, and the selective passing portion 72 allows the passage of liquid inside the tubular portion 71 and hinders the passage of powder.

FIG. 5B is an explanatory view showing a state in which the partition is contracted in the radial direction and passed through the opening of the first container.
As shown in FIG. 5B, the partition 70 has flexibility and can be made smaller in the radial direction than the opening of the first container 50 when an external force is applied. As a result, the partition 70 can be installed in the first container 50 from the outside. As shown in FIG. 6, the partition 70 is moved from the outside to the inside of the first container 50 through the opening of the first container 50 to release the force from the outside, and the partition 70 is originally moved inside the first container 50. The shape is restored, and the tubular portion 71 of the partition 70 is brought into contact with the inner peripheral surface of the first container 50.

In the carbonated water production apparatus 1, in the first container 50, the powder P of sodium hydrogen carbonate and citric acid is reacted with water W1 to generate carbonic acid gas. The partition 70 is made of a material that allows the passage of water W1 and blocks the passage of powder P. As the partition 70, for example, a polyurethane foam having a three-dimensional network structure can be used. In this case, the powder P is clogged at the partition 70, so that the passage of the powder P is hindered.

A carbonated water production method using the carbonated water production apparatus 1 configured as described above will be described.
First, predetermined preparations are made for the first container 50 and the second container 60 (container preparation step). Specifically, as shown in FIG. 6, the partition 70 is inserted into the first container 50 through an opening from the outside into the inside of the first container 50, and the partition 70 is set on the bottom side of the first container 50. At this time, since the tubular portion 71 of the partition 70 comes into contact with the inner peripheral surface of the first container 50, the partition 70 is accurately positioned.

Then, a predetermined amount of water W1 is filled into the bottom side of the first container 50 through the opening of the first container 50 and the selective passage portion 72 of the partition 70. At this time, the partition 70 is wetted with water W1. Here, it is necessary that the water W1 does not exceed the height of the selective passage portion 72 of the partition 70. After that, the carbonate and acid powder P is filled through the opening of the first container 50 and deposited on the selective passage portion 72 of the partition 70 in the first container 50. At this time, since the tubular portion 71 of the partition 70 is in contact with the inner peripheral surface of the first container 50, the powder P does not fall from the outside of the partition 70 to the bottom side. As a result, the water W1 and the powder P are separated in the first container 50. In this embodiment, sodium hydrogen carbonate is used as the carbonate and citric acid is used as the acid. At this time, since the partition 70 is wetted by the water W1 previously filled in the first container 50, the powder P easily adheres to the partition 70 and more effectively passes through the selective passing portion 72 of the powder P. Can be inhibited. Therefore, even if the partition 70 does not sufficiently inhibit the powder when it is not wet with the liquid, the partition 70 may exhibit the inhibitory property of the powder when wet with the liquid.

More specifically, the imposition of some powder P increases the viscous resistance between the powder P or between the powder P and the partition 70. As a result, the water-bearing powder in the vicinity of the mesh of the partition 70 becomes a solidified state, and clogging is likely to occur. Since the amount of water with respect to the powder P is small, the powder P hardly dissolves in the water W1. By adhering the powder P to the partition 70 in this way, the movement of the deposited powder P due to vibration or the like is also hindered.

On the other hand, water W2, which is a raw material for carbonated water, is placed in the second container 60. Here, the lower the temperature, the easier it is for the carbonic acid gas to dissolve in water, so it is desirable to cool the water W2 in advance before putting it in the second container 60.

After the container preparation step, as shown in FIG. 6, the first container 50 is screwed into the first piping section 10 and the second container 60 is screwed into the second piping section 20. After connecting the containers 50 and 60 to the piping portions 10 and 20, as an initial state, the on-off valve 32 of the connecting piping section 30 is opened and the on-off valve 42 of the communicating piping section 40 is closed ( Initial state setting process). As a result, the first container 50 and the second container 60 communicate with each other and are shielded from the outside air.

After the setting of the initial state is completed, as shown in FIG. 7, from the state where the water W1 and the powder P are separated, the first container 50 is shaken in the vertical direction, etc., and the water W1 is passed through the selective passage portion 72. 1 Move from the bottom side of the container 50 to the powder P. At this time, since the amount of water for the powder deposited on the selective passage portion 72 is sufficiently large, the clogging of the partition 70 is eliminated. When a sufficient amount of water W1 and powder P come into contact with each other, the powder P dissolves in water and a chemical reaction starts, and carbon dioxide gas is generated in the first container 50 (carbonic acid gas generation step). With the generation of carbon dioxide gas, the pressure inside the first container 50 and the second container 60 rises, and the carbon dioxide gas dissolves in the water W2 in the second container 60. The pressure in the second container 60 can be confirmed by the pressure gauge 25.

Here, when the pressure inside the first container 50 and the second container 60 exceeds a predetermined value, the internal fluid is discharged to the outside of the device through the release valves 12 of the first piping section 10 and the second piping section 20. NS. At this time, since each release valve 12 is covered with the cover 13, the water inside is not sprayed to the outside to contaminate the periphery of the device.

After the required amount of carbon dioxide gas is generated in the first container 50, the on-off valve 32 of the connecting piping section 30 is closed and the on-off valve 42 of the communicating piping section 40 is opened as shown in FIG. And. As a result, while the inside of the second container 60 is pressurized, the inside of the first container 50 can be decompressed and removed (first container decompression step).

After that, the carbon dioxide gas remaining in the second container 60 is dissolved in water W2 by shaking the second container 60 or the like. At this time, since the on-off valve 32 of the connecting piping portion 30 is in the closed state, even if the second container 60 is violently shaken at various angles, the liquid in the first container 50 is mixed in the second container 60. There is no. As a result, the surface area of water in contact with carbon dioxide gas can be increased, and the time required for vibration of the second container 60 can be shortened. After the carbon dioxide gas is sufficiently dissolved in water W2, the inside of the second container 60 is depressurized by opening the on-off valve 32 of the connecting piping portion 30 as shown in FIG. 9 (second container depressurizing step). As a result, the carbonated water in the second container 60 can be used.

As described above, according to the carbonated water production apparatus 1 of the present embodiment, the pressure inside the first container and the second container can be controlled independently. Further, since the open valve 12 is provided in the first piping portion 10 and the second piping portion 20, the pressure inside the apparatus is kept within a predetermined value. As a result, an excessive load is not applied to each part of the device and each of the containers 50 and 60, and the reliability of the device and the containers 50 and 60 can be ensured. Further, since the cover 13 for covering the release valve 12 is provided, the periphery of the device is not contaminated.

Further, since the water W1 and the powder P are partitioned by the selective passing portion 72 of the partition 70 in the first container 50, carbon dioxide gas can be generated at a desired timing. That is, unlike the case where the water W1 and the powder P are separated using a water-soluble wrapping paper, the dissolved state of the wrapping paper does not change depending on the water temperature, and by using the partition 70 of the present embodiment. It is not affected by the water temperature, and a stable reaction can be started after sealing. Further, carbon dioxide gas is not generated before the first container 50 is attached to the first piping portion 10, and the carbon dioxide gas can be used without waste.

In the above embodiment, the material of the partition 70 itself has a three-dimensional network structure, and the selective passing portion 72 allows the passage of the liquid inside the tubular portion 71 and hinders the passage of the powder. However, as shown in FIG. 10, for example, the partition 170 may structurally allow the passage of liquid and obstruct the passage of powder. The partition 170 of FIG. 10 is structurally flexible and has a structure that does not allow the passage of both liquid and powder.

The partition 170 includes a tubular portion 171 extending in the vertical direction, an upper surface portion 172 formed at the upper end of the tubular portion 171 and having a circular hole portion 172a in the center, and a donut-shaped hole portion 173a formed below the upper surface portion 172. It has a first step portion 173 having a portion, and a second step portion 174 formed below the first step portion 173 and having a predetermined hole portion. The first step portion 173 is formed in the same area or a larger area as the hole portion 172a of the upper surface portion 172 in a plan view, and is formed so as to close directly below the hole portion 172a of the upper surface portion 172. As a result, the liquid can pass through the inside of the cylinder portion 171 through the pore portions 172a and 173a, but the powder is hindered by the first stage portion 173. In particular, the powder tends to accumulate when water droplets adhere and cause clogging. That is, in this partition 170, the upper surface portion 172 and the first step portion 173 form the selective passing portion. By forming the second step portion 174 so as to overlap the hole portion 173a of the first step portion 173 in a plan view, the action of inhibiting powder passage is strengthened in the first step portion 173 and the second step portion 174. can do. As a result, even if the upper surface portion 172 and the first stage portion 173 do not sufficiently inhibit the powder passage, the partition 170 as a whole can exhibit the selective passage function.

Further, in the above-described embodiment, the release valve 12 is provided in the first piping portion 10 and the second piping portion 20, but if it is provided in at least one of these, the internal pressure is a predetermined value. When the pressure exceeds the above, the internal fluid can be discharged to the outside of the device. When it is provided in either one, it is preferably provided in the first piping portion 10. It is also possible to configure the carbonated water production apparatus 1 without the release valve 12.

Further, for example, as shown in FIG. 11, the diameters of the connecting piping portion 130 and the communicating piping portion 140 can be increased. As shown in FIG. 12, in the carbonated water production apparatus 101, the connection piping portion 130 is provided at the center of the piping portion main body 131, which is formed of resin and extends in the left-right direction, and opens and closes the flow path. It has an on-off valve 132 and auxiliary piping portions 133 arranged on the left and right sides of the piping portion main body 131 via a ring-shaped sealing material 134. The right end side of the piping portion main body 131 forms the first pipe portion 131a, and a male screw portion screwed with the female screw portion of the auxiliary piping portion 133 is formed on the outer peripheral surface of the first pipe portion 131a. Further, the left end side of the piping portion main body 131 forms the second pipe portion 131b, and a male screw portion screwing with the female screw portion of the auxiliary piping portion 133 is formed on the outer peripheral surface of the second pipe portion 131b. Each auxiliary piping portion 133 has a diameter-expanded portion 133a in which a female screw portion screwing with the piping portion main body 131 is formed on the inner peripheral surface, and a male screw portion screwing with the first piping portion 10 or the second piping portion 20 on the outer circumference. It has a normal diameter portion 133b formed on the surface.

As shown in FIG. 13, a return portion 133c is formed at an end portion of the auxiliary piping portion 133 on the enlarged diameter portion 133a on the piping portion main body 131 side. The return portion 133c has a closing portion 133c1 that closes the radial outer end of the passage in the diameter expanding portion 133a, and an extending portion 133c2 that extends from the radial inside of the closing portion 133c1 to the side opposite to the piping portion main body 131. .. When the passage of the auxiliary piping portion 133 is installed substantially horizontally, when the liquid is mixed with the gas that normally flows from the diameter portion 133b side to the diameter expansion portion 133a side, the liquid is heavier than the gas, so the auxiliary piping portion 133 Accumulates on the lower side of the passage, and the return portion 133c hinders the flow to the piping portion main body 131 side. As a result, when the carbon dioxide gas generated in the first container 50 flows to the second container 60 side, even if the liquid in the first container 50 infiltrates into the connection piping portion 130, the return portion 133c 2 Distribution to the 60 side of the container is hindered.

Further, as shown in FIG. 13, the communication piping portion 140 includes, for example, a piping portion main body 141 formed of resin and extending in the vertical direction, an on-off valve 142 provided in the center of the piping portion main body 141 to open and close the flow path, and a ring. It has an auxiliary piping portion 143 arranged below the piping portion main body 141 via the shape sealing material 144. The lower end side of the piping portion main body 141 forms the first pipe portion 141a, and the outer peripheral surface of the first pipe portion 141a is formed with a male screw portion to be screwed with the female screw portion of the auxiliary piping portion 143. The auxiliary piping portion 143 has a diameter-expanded portion 143a in which a female screw portion to be screwed with the piping portion main body 141 is formed on the inner peripheral surface, and a normal diameter portion in which a male screw portion to be screwed with the first piping portion 10 is formed on the outer peripheral surface. It has a part 143b and. Further, the upper end side of the piping portion main body 141 forms the second pipe portion 141b, and a male screw portion to be screwed with the terminal cap 115 is formed on the outer peripheral surface of the second pipe portion 141b. The end cap 115 is formed of, for example, resin and covers the outside of the second pipe portion 141b on the upper end side. In this carbonated water production apparatus 101, the piping section main body 141, on-off valve 142 and auxiliary piping section 143 of the communication piping section 140 are the same as the piping section main body 131, on-off valve 132 and auxiliary piping section 143 of the connecting piping section 130.
