Description

炭酸水用卓上ポットTabletop pot for carbonated water
　本発明は、卓上に配置され、予め貯留された炭酸水を、適時に供給するために用いられる炭酸水用卓上ポットに関する。 The present invention relates to a tabletop pot for carbonated water that is placed on a tabletop and used to supply prestored carbonated water in a timely manner.
　飲食店においては、原液を炭酸水で希釈する、いわゆるソーダ割りの飲料が提供されている。
　かかるソーダ割りの飲料は、通常、店員が、原液に対し、予め定めた希釈率で炭酸水を注入することにより作製される。このため、ソーダ割りの飲料を提供する店舗においては、ソーダ割りの原液の濃度が一律となっており、客の好みに応じてソーダ割り飲料における原液の濃さを調整することは、一般的には行われていない。 In restaurants, so-called soda-mixed beverages, in which the undiluted solution is diluted with carbonated water, are provided.
Such soda-mixed beverages are usually prepared by a store clerk injecting carbonated water into the undiluted solution at a predetermined dilution rate. For this reason, the concentration of the undiluted solution of soda-wari is uniform at stores that offer beverages mixed with soda. is not done.
　これに対し、例えば、炭酸水を大量に貯留したポットを、卓上に載置しておいて、客に利用してもらう方法が考えられる。すなわち、客には原液を提供し、これをポットの炭酸水を用いて希釈してもらうという方法である。
　この場合、客は、原液の濃度を自分の好みに調整することが可能となる。 On the other hand, for example, a method is conceivable in which a pot containing a large amount of carbonated water is placed on a table and used by customers. In other words, customers are provided with the undiluted solution, which is then diluted with a pot of carbonated water.
In this case, the customer can adjust the concentration of the undiluted solution to their liking.
　ところが、炭酸水を貯留するために、いわゆるピッチャーのような公知のポットを採用した場合は、貯留された炭酸水の炭酸ガスが抜け易いという欠点がある。
　そうすると、この場合、ポットに注入した直後の炭酸水と、客に提供した時点での炭酸水と、提供後且つ一定時間経過後の炭酸水とでは、それぞれ炭酸の強さが大きく異なることになる。 However, when a known pot such as a so-called pitcher is used to store carbonated water, there is a drawback that the carbon dioxide gas in the stored carbonated water is easily released.
If so, in this case, the carbonated water immediately after being poured into the pot, the carbonated water at the time of serving to the customer, and the carbonated water after the serving and after a certain period of time have passed will all have significantly different strengths of carbonation. .
　一方で、炭酸水とは異なるが、ビール等の飲料の炭酸ガスが抜けることを抑制するサーバが知られている。
　例えば、ビール容器に装着する分配手段と、加圧ガスを封入するガスボンベと、分配手段とガスボンベを連結して加圧ガスを所定の圧力に調圧して容器内の液面を加圧するガス供給手段を備えるビールサーバにおいて、ガスボンベは、１ＭＰａ未満の圧力でガスを封入するガスボンベであるビールサーバ（サーバ）が知られている（例えば、特許文献１参照）。
　また、高圧ガスボンベから低圧ガスボンベへの圧力ガス移充填装置と、該圧力ガス移充填装置により圧力ガスが移充填された低圧ガスボンベを装着可能であり、かつ、ディスペンサの操作により所望量の飲料を抽出可能な卓上飲料サーバとを備えてなり、かつ、低圧ガスボンベがガス放出後再充填可能なものである飲料提供設備（サーバ）が知られている（例えば、特許文献２参照）。 On the other hand, although different from carbonated water, there is known a server that suppresses the release of carbon dioxide from beverages such as beer.
For example, a distribution means attached to a beer container, a gas cylinder for enclosing a pressurized gas, and a gas supply means for connecting the distribution means and the gas cylinder to adjust the pressure of the pressurized gas to a predetermined pressure to pressurize the liquid level in the container. A beer server (server), which is a gas cylinder that seals gas at a pressure of less than 1 MPa, is known (see, for example, Patent Document 1).
In addition, it is possible to install a pressure gas transfer filling device from a high pressure gas cylinder to a low pressure gas cylinder and a low pressure gas cylinder filled with pressure gas by the pressure gas transfer filling device, and extract a desired amount of beverage by operating a dispenser. Beverage serving installations (servers) are known, comprising a tabletop beverage server capable of serving beverages, and in which the low-pressure gas cylinders are refillable after gas release (see, for example, US Pat.

　しかしながら、特許文献１及び２に記載のサーバは、何れもガスボンベを備える必要があるため、持ち運びが困難であり、卓上に配置するにもスペースを要するという問題がある。 However, the servers described in Patent Documents 1 and 2 are both difficult to carry because they need to be equipped with a gas cylinder, and there is a problem that they require space even when placed on a table.
　本発明は上記事情に鑑みてなされたものであり、持ち運びが容易であり、且つ、経時的に炭酸水の炭酸ガスが抜けることを抑制することができる炭酸水用卓上ポットを提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a tabletop pot for carbonated water that is easy to carry and that can suppress the release of carbon dioxide from carbonated water over time. and

　本発明の炭酸水用卓上ポットにおいては、第１容器部の第１容器本体部が、第２容器部の第２容器本体部に内蔵されており、第１容器本体部及び第２容器本体部の共通する開口部には蓋部が取り付けられており、蓋部には、流通管が取り付けられた流通継手部が設けられており、第１容器本体部には、連通管が取り付けられた第１連通継手部が設けられており、第２容器本体部には、連通管が取り付けられた第２連通継手部と、第２空間部に外部から炭酸ガスを注入するための炭酸ガス継手部とが設けられていることが好ましい。 In the tabletop pot for carbonated water of the present invention, the first container main body of the first container is incorporated in the second container main body of the second container, and the first container main body and the second container main body A lid is attached to the common opening of the lid, the lid is provided with a circulation joint to which a circulation pipe is attached, and the first container body is provided with a communication pipe to which a communication pipe is attached. A first communication joint is provided, and the second container main body has a second communication joint to which a communication pipe is attached, and a carbon dioxide gas joint for injecting carbon dioxide from the outside into the second space. is preferably provided.
　本発明の炭酸水用卓上ポットにおいては、第１空間部及び第２空間部が、炭酸ガスにより、大気圧よりも高い圧力で維持されている。
　そして、第１空間部に貯留された炭酸水は、流通管内にも充填され、その状態で注出ノズル部の栓を付勢している。
　このため、炭酸水用卓上ポットにおいては、注出ノズル部の止め栓を開放させることにより、簡単に炭酸水を注出することが可能となっている。 In the tabletop pot for carbonated water of the present invention, the first space and the second space are maintained at a pressure higher than the atmospheric pressure by carbon dioxide gas.
The carbonated water stored in the first space also fills the inside of the flow pipe, and in this state, biases the plug of the pouring nozzle.
Therefore, in the tabletop pot for carbonated water, carbonated water can be easily poured out by opening the stopcock of the pouring nozzle portion.
　ここで、炭酸水を注出することにより、第１空間部の第１圧力が低下すると考えられるが、炭酸水用卓上ポットにおいては、減圧弁により、第２空間部における第２圧力が、第１空間部における第１圧力よりも大きくなるように調整されているので、第１空間部の圧力の低下分を、第２空間部から炭酸ガスを流入させることで補充することが可能となる。

　これにより、経時的に炭酸水の炭酸ガスが抜けることを抑制することができる。また、一定量の炭酸ガスを含む炭酸水を、一定の勢いで注出させることが可能となる。 Here, it is considered that the first pressure in the first space decreases by pouring out the carbonated water. Since it is adjusted to be higher than the first pressure in the first space, it is possible to make up for the pressure drop in the first space by introducing carbon dioxide gas from the second space.
Further, the pressure reducing valve makes it possible to keep the first pressure in the first space substantially constant.
Thereby, it is possible to suppress the release of carbon dioxide from carbonated water over time. In addition, carbonated water containing a certain amount of carbon dioxide gas can be poured out at a certain rate.

Not always connected. Therefore, the tabletop pot for carbonated water has a compact structure and is extremely easy to carry. As a result, for example, it can be easily placed on a table according to a customer's order, and can be easily retrieved from there after use.
　本発明の炭酸水用卓上ポットにおいては、第２圧力を、第１圧力よりも１．４倍以上大きいものとすることにより、第１圧力の低下を十分に補充することが可能となるので、第１空間部に十分な量の炭酸水を貯留させることが可能となる。これにより、炭酸水用卓上ポットに炭酸水を補充する頻度を減らすことができる。
　また、第２圧力を１．８ＭＰａ以下とすることにより、過度な耐圧性を要しないので、第１容器部及び第２容器部を比較的軽量なものとすることができる。 In the tabletop pot for carbonated water of the present invention, by setting the second pressure to be 1.4 times or more higher than the first pressure, it is possible to sufficiently replenish the decrease in the first pressure. A sufficient amount of carbonated water can be stored in the first space. As a result, it is possible to reduce the frequency of replenishing the carbonated water desktop pot with carbonated water.
Further, by setting the second pressure to 1.8 MPa or less, excessive pressure resistance is not required, so the first container portion and the second container portion can be made relatively lightweight.

　また、第１蓋部を取り外すことにより、第１容器本体部の内部を容易に洗浄することができ、第２蓋部を取り外すことにより、第２容器本体部の内部を容易に洗浄することが可能となる。 In the tabletop pot for carbonated water of the present invention, the first container portion and the second container portion are independent from each other, and the opening portion of the first container main body portion is provided with the first communication joint portion and the circulation joint portion. In the case of a structure in which the first lid is attached and the second lid provided with the second communication joint and the carbon dioxide gas joint is attached to the opening of the second container main body, taking in and out of carbon dioxide, etc. Since this can be done at the joints of the corresponding lids, the structure of the container body can be simplified.
Further, the inside of the first container body can be easily washed by removing the first lid, and the inside of the second container body can be easily washed by removing the second lid. It becomes possible.

　このように、炭酸水用卓上ポット１００においては、炭酸ガスの出し入れ等を、対応する各蓋部の継手部で行うことができるので、容器本体部の構造をシンプルなものとすることができる。
　また、第１蓋部１ｂを取り外すことにより、第１容器本体部１ａの内部を容易に洗浄することができ、第２蓋部２ｂを取り外すことにより、第２容器本体部２ａの内部を容易に洗浄することが可能である。 As described above, in the tabletop pot for carbonated water 100, carbon dioxide can be taken in and out at the corresponding joints of the respective lids, so that the structure of the container main body can be simplified.
Further, by removing the first lid portion 1b, the inside of the first container body portion 1a can be easily washed, and by removing the second lid portion 2b, the inside of the second container body portion 2a can be easily cleaned. It can be washed.
　ここで、炭酸水用卓上ポット１００における第１空間部Ｓ１の第１圧力及び第２空間部Ｓ２の第２圧力について説明する。
　炭酸水用卓上ポット１００において、第１空間部Ｓ１の第１圧力及び第２空間部Ｓ２の第２圧力は、いずれも大気圧よりも高い圧力で維持されている。これにより、炭酸水は、流通管５内にも充填され、更に、注出ノズル部４側を付勢した状態となっている。その結果、注出ノズル部４の止め栓を開放するだけで、炭酸水を注出することが可能となる。 Here, the first pressure of the first space S1 and the second pressure of the second space S2 in the tabletop pot for carbonated water 100 will be described.
In the tabletop pot for carbonated water 100, both the first pressure of the first space S1 and the second pressure of the second space S2 are maintained at a pressure higher than the atmospheric pressure. As a result, the carbonated water is filled also in the flow pipe 5, and furthermore, the pouring nozzle portion 4 side is biased. As a result, carbonated water can be poured out simply by opening the stopcock of the pouring nozzle portion 4 .
　炭酸水用卓上ポット１００において、第１圧力の大きさは、常圧より大きくなっていればよいが、０．５ＭＰａ以上であることが好ましい。なお、第１圧力は一定の幅のある範囲であってもよい。
　第１圧力の大きさが０．５ＭＰａ未満であると、第１圧力の大きさが上記範囲内にある場合と比較して、炭酸水Ｗが注出ノズル部４を付勢する力が弱いため、止め栓を開いた際に十分な勢いで炭酸水Ｗが注出されない傾向にある。 In the tabletop pot for carbonated water 100, the magnitude of the first pressure may be higher than normal pressure, but is preferably 0.5 MPa or higher. Note that the first pressure may be in a certain range.
When the magnitude of the first pressure is less than 0.5 MPa, compared to when the magnitude of the first pressure is within the above range, the force with which the carbonated water W urges the pouring nozzle portion 4 is weak. , the carbonated water W tends not to be poured out with sufficient force when the stopper is opened.
　なお、第１圧力及び第２圧力は、１．８ＭＰａ以下であることが好ましい。この場合、安全性に優れると共に、過度な耐圧性を要しないので、第１容器部１及び第２容器部２を比較的軽量なものとすることができる。 It should be noted that the first pressure and the second pressure are preferably 1.8 MPa or less. In this case, the first container part 1 and the second container part 2 can be made relatively light because they are excellent in safety and do not require excessive pressure resistance.
　第２圧力の大きさは、第１圧力よりも大きければよいが、１．４倍以上大きいことが好ましく、１．６倍以上大きいことがより好ましい。なお、第２圧力は一定の幅のある範囲であってもよい。
　第２圧力の大きさを第１圧力より大きくすることにより、炭酸水Ｗを注出後、第２空間部Ｓ２から第１空間部Ｓ１に炭酸ガスを補充することが可能となる。すなわち、炭酸水Ｗの注出に伴い第１空間部Ｓ１の圧力が第１圧力よりも低下したとしても、炭酸ガスを補充することにより、第１圧力を維持することが可能となる。
　また、第２圧力を、第１圧力よりも１．４倍以上大きいものとすることにより、第１圧力の低下を十分に補充することが可能となるので、第１空間部Ｓ１に十分な量の炭酸水を貯留させることが可能となる。これにより、炭酸水用卓上ポット１００に炭酸水Ｗを補充する頻度を減らすことができる。 The magnitude of the second pressure may be higher than the first pressure, preferably 1.4 times or more, more preferably 1.6 times or more. Note that the second pressure may be in a certain range.
By making the magnitude of the second pressure larger than the first pressure, it becomes possible to replenish carbon dioxide gas from the second space S2 to the first space S1 after the carbonated water W is poured. That is, even if the pressure in the first space S1 becomes lower than the first pressure as the carbonated water W is poured out, the first pressure can be maintained by replenishing the carbon dioxide gas.
Further, by setting the second pressure to be 1.4 times or more higher than the first pressure, it is possible to sufficiently replenish the decrease in the first pressure. of carbonated water can be stored. As a result, the frequency of replenishing the carbonated water tabletop pot 100 with the carbonated water W can be reduced.
　このように、炭酸水用卓上ポット１００においては、第１圧力が維持されるので、経時的に炭酸水Ｗの炭酸ガスが抜けることを抑制することができる。また、一定量の炭酸ガスを含む炭酸水Ｗを、一定の勢いで注出させることが可能となる。
　また、第２容器部２に貯留された炭酸ガスを利用して、第１圧力の低下分を補充できるので、コンパクトな構造とすることができ、持ち運びも極めて容易となる。 Thus, in the tabletop pot for carbonated water 100, the first pressure is maintained, so it is possible to suppress the release of carbon dioxide gas from the carbonated water W over time. Further, it becomes possible to pour out the carbonated water W containing a certain amount of carbon dioxide gas at a certain force.
In addition, since the carbon dioxide gas stored in the second container part 2 can be used to replenish the first pressure drop, the structure can be made compact and the portability is extremely easy.
　炭酸水用卓上ポット１００において、炭酸水Ｗが貯留されていない場合の第１空間部Ｓ１の容積は、コンパクトでありながら、十分な量の炭酸水Ｗを貯留するという観点から、３５０～３５００ｃｍ３であることが好ましい。
　また、第２空間部Ｓ２の容積は、コンパクトでありながら、十分な量の炭酸水Ｗが注出された場合であっても第１圧力を維持するための十分な炭酸ガスを貯留するという観点から、４９０～５６００ｃｍ３であることが好ましい。 In the tabletop pot for carbonated water 100, the volume of the first space S1 when carbonated water W is not stored is 350 to 3500 cm 3 from the viewpoint of storing a sufficient amount of carbonated water W while being compact. is preferred.
In addition, the volume of the second space S2 is compact, but from the viewpoint of storing enough carbon dioxide gas to maintain the first pressure even when a sufficient amount of carbonated water W is poured out. Therefore, it is preferably 490 to 5600 cm 3 .
　炭酸水用卓上ポット１００において、注出ノズル部４は、流通管５（詳しくは外側流通管５ａ）の先端に設けられる。
　具体的には、注出ノズル部４は、炭酸水Ｗを注出するノズル口部４ａと、炭酸水Ｗの流路に設けられた止め栓（図示しない）と、該止め栓を開閉させるための注出レバー４ｂとを有する。 In the tabletop pot for carbonated water 100, the pouring nozzle part 4 is provided at the tip of the flow pipe 5 (specifically, the outer flow pipe 5a).
Specifically, the pouring nozzle portion 4 includes a nozzle mouth portion 4a for pouring out the carbonated water W, a stopcock (not shown) provided in the flow path of the carbonated water W, and a stopper for opening and closing the stopcock. and a pouring lever 4b.
　注出ノズル部４においては、第１空間部Ｓ１の圧力により、流通管５内の炭酸水Ｗが、注出ノズル部４側に付勢されているので、注出レバー部４ｂを操作して、止め栓を開放することにより、ノズル口部４ａから炭酸水Ｗが注出されるようになっている。
　また、注出レバー部４ｂを操作して、止め栓で閉鎖することにより、ノズル口部４ａからの炭酸水Ｗの注出は停止される。 In the pouring nozzle portion 4, the carbonated water W in the flow pipe 5 is urged toward the pouring nozzle portion 4 by the pressure in the first space S1, so that the pouring lever portion 4b is operated. , the carbonated water W is poured out from the nozzle opening 4a by opening the stopper.
Further, by operating the pouring lever portion 4b and closing it with a stopcock, the pouring of the carbonated water W from the nozzle mouth portion 4a is stopped.
　保持部６は、第１容器部１及び第２容器部２を保持するためのものである。
　図３は、第１実施形態に係る炭酸水用卓上ポットにおいて、容器部が保持部に取り付けられる状態を説明するための説明図である。
　図３に示すように、保持部６は、いわゆるホルダーであり、二つの穴部６ａを有している。そして、各穴部６ａから、第１蓋部１ｂの螺合部１ｂ１及び第２蓋部２ｂの螺合部２ｂ１が垂下するように、第１蓋部１ｂ及び第２蓋部２ｂが保持部６に取り付けられる。このとき、保持部６と第１蓋部１ｂ及び第２蓋部２ｂとは、ボルト等の留め具（図示しない）により固定される。
　一方で、第１容器部１の第１開口部１ａ１、及び、第２容器部２の第２開口部２ａ１、の内面には、それぞれ、螺旋状の溝部が設けられている。

At this time, since the communication pipe 3 is provided with the check valve 3b, the air does not flow from the first space S1 to the second space S2, and the pressure in the first space S1 rises. do.
When the pressure in the first space S1 rises too much, the first safety valve 13c operates to release the air in the first space S1 to the outside, thereby returning the pressure to a predetermined level.
　次に、第２容器部２の第２空間部Ｓ２に、炭酸ガス継手部２３ｂから炭酸ガスを注入する炭酸ガス注入ステップを行う。
　このとき、第２空間部２の圧力が十分に高くなると、連通管３には減圧弁３ａが設けられているので、第２空間部２の炭酸ガスの一部が、減圧弁３ａ、逆止弁３ｂを介して、第１空間部１に注入される。
　その結果、逆止弁３ａにより、第１空間部Ｓ１の圧力と第２空間部２の圧力とが所定の値となるように調整される。
　なお、第２空間部Ｓ２内の圧力が上昇し過ぎた場合は、第２安全弁２３ｃが作動して、第１空間部Ｓ１内の空気を外部に放出することにより、所定の圧力に戻される。
　こうして、炭酸水用卓上ポット１００に炭酸水Ｗ及び炭酸ガスが充填される。 Next, a carbon dioxide gas injection step of injecting carbon dioxide gas from the carbon dioxide gas coupling portion 23b into the second space S2 of the second container portion 2 is performed.
At this time, when the pressure in the second space 2 becomes sufficiently high, since the communication pipe 3 is provided with the pressure reducing valve 3a, part of the carbon dioxide gas in the second space 2 is It is injected into the first space 1 through the valve 3b.
As a result, the check valve 3a adjusts the pressure in the first space S1 and the pressure in the second space 2 so as to have predetermined values.
When the pressure in the second space S2 rises too much, the second safety valve 23c operates to release the air in the first space S1 to the outside, thereby returning the pressure to a predetermined level.
Thus, the tabletop pot 100 for carbonated water is filled with the carbonated water W and the carbon dioxide gas.
　炭酸水用卓上ポット１００における炭酸水Ｗの注出方法においては、注出ノズル部４の注出レバー部ｂ４を操作して、止め栓を開放することにより、止め栓に付勢された流通管５内の炭酸水Ｗが注出される。
　このとき、上述したように、炭酸水Ｗの注出により、第１空間部Ｓ１の第１圧力が低下することになるが、この場合は、減圧弁３ａを介して、第２空間部Ｓ２から炭酸ガスが第１空間部Ｓ１に補充されることで、一定の第１圧力が維持される。なお、炭酸水Ｗが十分に少なくなるまで、第２空間部Ｓ２から第１空間部Ｓ１に炭酸ガスを補充することを踏まえて、上述したように、第２圧力は高く設定される。 In the pouring method of the carbonated water W in the tabletop pot for carbonated water 100, the pouring lever portion b4 of the pouring nozzle portion 4 is operated to open the stopcock, whereby the flow pipe urged by the stopcock is opened. Carbonated water W in 5 is poured out.
At this time, as described above, the first pressure in the first space S1 is reduced by pouring out the carbonated water W. A constant first pressure is maintained by replenishing the first space S1 with carbon dioxide gas. Note that the second pressure is set high, as described above, in consideration of replenishing carbon dioxide from the second space S2 to the first space S1 until the amount of carbonated water W becomes sufficiently low.
　そして、第１空間部Ｓ１の炭酸水Ｗが十分に少なくなった場合は、炭酸水注入ステップと同様にして、第１空間部Ｓ１に、流通継手部１３ｂから炭酸水を注入し、炭酸ガス注入ステップと同様にして、第２空間部２に、炭酸ガス継手部２３ｂから炭酸ガスを注入することにより、これらを補充する。 Then, when the amount of carbonated water W in the first space S1 is sufficiently low, in the same manner as in the carbonated water injection step, carbonated water is injected into the first space S1 from the flow joint portion 13b to inject carbon dioxide gas. In the same manner as the step, the second space 2 is replenished by injecting carbon dioxide gas from the carbon dioxide joint 23b.
（第２実施形態）
　次に、本発明に係る炭酸水用卓上ポットの第２実施形態について説明する。

In the tabletop pot for carbonated water 101 , the carbonated water W stored inside is poured out from the pouring nozzle portion 54 .
　炭酸水用卓上ポット１０１においては、第１容器部５１の第１容器本体部５１ａが、第２容器部５２の第２容器本体部５２ａに内蔵されており、第１容器本体部５１ａ及び第２容器本体部５２ａの共通する開口部（第１開口部５１ａ１及び第２開口部５２ａ１）には蓋部５１ｂが取り付けられている。
　そして、第１容器部５１は、その内部に、第１空間部Ｓ１を有している。すなわち、第１空間部Ｓ１は、第１容器本体部５１ａ及び蓋部５１ｂにより密閉された空間となっている。
　また、第２容器部５２は、その内部の第１容器本体部５１ａの外側に、第２空間部Ｓ２を有している。すなわち、第２空間部Ｓ２は、第１容器本体部５１ａと第２容器本体部５２ａとの間の密閉された空間となっている。
　そして、第１空間部Ｓ１には、炭酸ガスが充填され、且つ、炭酸水Ｗが貯留されている。また、第２空間部Ｓ２には、炭酸ガスが充填されている。なお、第１容器部５１には、第１空間部Ｓ１の第１圧力を測定するための圧力計（図示しない）が設けられていてもよく、第２容器部２には、第２空間部Ｓ２の第２圧力を測定するための圧力計（図示しない）が設けられていてもよい。 In the tabletop pot for carbonated water 101, the first container body portion 51a of the first container portion 51 is incorporated in the second container body portion 52a of the second container portion 52. A lid portion 51b is attached to a common opening portion (first opening portion 51a1 and second opening portion 52a1) of the container main body portion 52a.
And the 1st container part 51 has the 1st space part S1 in the inside. That is, the first space S1 is a space sealed by the first container main body 51a and the lid 51b.
Further, the second container portion 52 has a second space portion S2 outside the first container main body portion 51a therein. That is, the second space S2 is a closed space between the first container body 51a and the second container body 52a.
Carbon dioxide gas is filled in the first space S1, and carbonated water W is stored. Further, the second space S2 is filled with carbon dioxide gas. Note that the first container portion 51 may be provided with a pressure gauge (not shown) for measuring the first pressure in the first space portion S1, and the second container portion 2 may be provided with a second space portion. A pressure gauge (not shown) may be provided to measure the second pressure of S2.
　このように、第１容器本体部５１ａと第２容器本体部５２ａとの二重構造とすることにより、炭酸水用卓上ポット１０１自体をよりコンパクトなものとすることができる。
　また、開口部が共通するので、開口部に蓋部５１ｂを取り付けることにより、開口部の開口が封止され、第１容器部５１及び第２容器部５２を同時に密閉することができる。
　また、蓋部５１ｂを取り外すことにより、第１容器本体部５１ａの内部を容易に洗浄することが可能となる。
　また、第２空間部Ｓ２を有しているので、炭酸水Ｗに温度変化が生じることを極力抑制することができる。 In this way, by forming the double structure of the first container main body 51a and the second container main body 52a, the desktop pot for carbonated water 101 itself can be made more compact.
In addition, since the openings are shared, the openings of the openings are sealed by attaching the lid portion 51b to the openings, so that the first container portion 51 and the second container portion 52 can be sealed at the same time.
Further, by removing the lid portion 51b, the inside of the first container main body portion 51a can be easily washed.
Moreover, since it has the 2nd space part S2, it can suppress that the carbonated water W changes in temperature as much as possible.
　炭酸水用卓上ポット１０１において、第１容器部５１は、開口した第１開口部５１ａ１を有する円柱状の第１容器本体部５１ａを有しており、第２容器部５２は、開口した第２開口部５２ａ１を有する円柱状の第２容器本体部５２ａを有している。
　ここで、第１容器本体部５１ａ及び第２容器本体部５２ａの材質は、耐圧性を有するものであれば、特に限定されず、公知の金属や樹脂を採用することができる。それらの中でも、第１容器本体部５１ａ及び第２容器本体部５２ａの材質としては、気密性、耐酸性の観点から、ステンレス鋼を採用することが好ましく、若しくは、耐酸性、軽量化の観点から、アクリル樹脂、ポリアセタール樹脂又はポリプロピレン樹脂を採用することが好ましい。なお、第１容器本体部５１ａ及び第２容器本体部５２ａの材質は、互いに同一であっても異なっていてもよい。 In the tabletop pot for carbonated water 101, the first container portion 51 has a cylindrical first container body portion 51a having a first opening portion 51a1, and the second container portion 52 has a second opening portion 51a1. It has a cylindrical second container main body 52a having an opening 52a1.
Here, the material of the first container body portion 51a and the second container body portion 52a is not particularly limited as long as it has pressure resistance, and known metals and resins can be used. Among them, as the material of the first container body 51a and the second container body 52a, it is preferable to adopt stainless steel from the viewpoint of airtightness and acid resistance, or from the viewpoint of acid resistance and weight reduction. , acrylic resin, polyacetal resin or polypropylene resin. The materials of the first container body portion 51a and the second container body portion 52a may be the same or different.
　炭酸水用卓上ポット１０１においては、第１開口部５１ａ１及び第２開口部５２ａ１の周縁に、共通するように、環状の蓋受け部５２ｂが設けられている。すなわち、蓋受け部５２ｂは、第１容器本体部５１ａの第１開口部５１ａ１周縁に取り付けられ、同時に、第２容器本体部５２ａの第２開口部５２ａ１周縁に取り付けられている。
　なお、第１容器本体部５１ａ又は第２容器本体部５２ａへの蓋受け部５２ｂの取付け方法は、特に限定されず、ボルト等の留め具を用いてもよく、溶接等により一体化してもよい。 In the tabletop pot for carbonated water 101, an annular lid receiving portion 52b is provided so as to be common to the periphery of the first opening portion 51a1 and the second opening portion 52a1. That is, the lid receiving portion 52b is attached to the periphery of the first opening 51a1 of the first container body 51a, and at the same time, is attached to the periphery of the second opening 52a1 of the second container body 52a.
The method of attaching the lid receiving portion 52b to the first container body portion 51a or the second container body portion 52a is not particularly limited. .
　炭酸水用卓上ポット１０１において、蓋受け部５２ｂには、蓋部５１ｂが嵌合されている。
　このとき、蓋受け部５２ｂと蓋部５１ｂとは、例えば、ボルト等の留め具（図示しない）により固定される。これにより、第１容器部５１の内部、及び、第２容器部５２の内部は同時に密閉される。なお、この場合、気密性を向上させる観点から、蓋受け部５２ｂと蓋部５１ｂとの間に、Ｏリング、パッキン等を介在させることが好ましい。
　なお、蓋部５１ｂは、留め具を取り外すことにより、蓋受け部５２ｂに対して脱着可能となっている。 In the tabletop pot for carbonated water 101, the lid portion 51b is fitted to the lid receiving portion 52b.
At this time, the lid receiving portion 52b and the lid portion 51b are fixed by fasteners (not shown) such as bolts. Thereby, the inside of the first container part 51 and the inside of the second container part 52 are sealed at the same time. In this case, from the viewpoint of improving airtightness, it is preferable to interpose an O-ring, a packing, or the like between the lid receiving portion 52b and the lid portion 51b.
The lid portion 51b can be attached to and detached from the lid receiving portion 52b by removing the fastener.
　炭酸水用卓上ポット１０１において、蓋部５１ｂには、蓋部５１ｂを上下方向に貫通する、流通継手部６３ｂと、安全弁６３ｃとが設けられている。すなわち、流通継手部６３ｂ及び安全弁６３ｃは、第１空間部Ｓ１と、第１容器部５１の外部とを連絡することが可能となっている。
　また、第１容器本体部５１ａには、第１連通継手部６３ａが設けられており、第２容器本体部５２ａには、第２連通継手部７３ａと、炭酸ガス継手部７３ｂとが設けられている。 In the tabletop pot for carbonated water 101, the lid portion 51b is provided with a circulation joint portion 63b and a safety valve 63c, which penetrate the lid portion 51b in the vertical direction. That is, the flow joint portion 63b and the safety valve 63c can communicate the first space portion S1 and the outside of the first container portion 51 with each other.
Further, the first container body portion 51a is provided with a first communication joint portion 63a, and the second container body portion 52a is provided with a second communication joint portion 73a and a carbon dioxide gas joint portion 73b. there is
　蓋部５１ｂにおいて、流通継手部６３ｂには、流通管５５が取り付けられる。また、流通継手部６３ｂには、第１開閉弁が内蔵されている。
　具体的には、流通管５５は、流通継手部６３ｂに取り付けられた、第１空間部Ｓ１の外側に位置する外側流通管５５ａと、第１空間部Ｓ１の内側に位置する内側流通管５５ｂ（サイフォン管）とを有する。なお、外側流通管５５ａは、流通継手部６３ｂから着脱可能となっている。 In the lid portion 51b, the circulation pipe 55 is attached to the circulation joint portion 63b. Further, a first on-off valve is incorporated in the flow joint portion 63b.
Specifically, the flow pipe 55 includes an outer flow pipe 55a located outside the first space S1 and an inner flow pipe 55b ( siphon tube). The outer circulation pipe 55a is detachable from the circulation joint portion 63b.
　すなわち、外側流通管５５ａは、一端が、注出ノズル部５４に取り付けられ、他端が、流通継手部６３ｂに取り付けられる。
　また、内側流通管５５ｂは、一端が、流通継手部６３ｂに取り付けられ、他端が、第１空間部Ｓ１に貯留された炭酸水Ｗに浸漬される。
　これにより、第１容器部５１の第１空間部Ｓ１と、注出ノズル部５４内とが流通継手部６３ｂの第１開閉弁を介して連通し、炭酸水Ｗの第１空間部Ｓ１から注出ノズル部５４への流入が可能となる。 That is, the outer circulation pipe 55a has one end attached to the pouring nozzle portion 54 and the other end attached to the circulation joint portion 63b.
One end of the inner circulation pipe 55b is attached to the circulation joint portion 63b, and the other end is immersed in the carbonated water W stored in the first space S1.
As a result, the first space portion S1 of the first container portion 51 and the inside of the pouring nozzle portion 54 communicate with each other through the first on-off valve of the flow joint portion 63b, and the carbonated water W is poured from the first space portion S1. Flow into the outlet nozzle portion 54 becomes possible.
　例えば、流通継手部６３ｂにおいては、第１開閉弁を開放し、且つ、外側流通管５５ｂを取り外すことにより、流通継手部６３ｂを介して、第１空間部Ｓ１を大気に開放することができる。
　また、第１開閉弁を開放し、且つ、外側流通管５５ｂを取り付けることにより、流通継手部６３ｂを介して、第１空間部Ｓ１と注出ノズル部５４ｂ内とを連通させることができる。
　また、第１開閉弁を閉鎖することにより、流通継手部６３ｂを封鎖することができる。 For example, in the circulation joint portion 63b, the first space S1 can be opened to the atmosphere via the circulation joint portion 63b by opening the first on-off valve and removing the outer circulation pipe 55b.
Further, by opening the first on-off valve and attaching the outer circulation pipe 55b, the first space S1 and the inside of the pouring nozzle 54b can be communicated with each other via the circulation joint 63b.
Also, by closing the first on-off valve, the flow joint portion 63b can be blocked.
　蓋部５１ｂにおいて、安全弁６３ｃは、第１空間部Ｓ１の圧力を開放するための弁である。
　安全弁６３ｃにおいては、第１空間部Ｓ１の第１圧力が一定値を超えると、安全弁６３ｃが開き、第１空間部Ｓ１の炭酸ガスを自動的に外部に放出するようになっている。すなわち、安全弁６３ｃは、第１圧力を一定に保つ機能を有する。なお、かかる一定値は任意に設定することができる。
　なお、安全弁６３ｃは、第１圧力の異常時に炭酸ガスを放出する際に利用することの他、使用前の第１空間部Ｓ１に炭酸ガスを充填する際、若しくは、使用後の第１空間部Ｓ１から炭酸ガスを抜く際に利用することも可能である。 In the lid portion 51b, the safety valve 63c is a valve for releasing the pressure in the first space portion S1.
In the safety valve 63c, when the first pressure in the first space S1 exceeds a certain value, the safety valve 63c opens to automatically release the carbon dioxide in the first space S1 to the outside. That is, the safety valve 63c has a function of keeping the first pressure constant. Note that such a constant value can be set arbitrarily.
The safety valve 63c is used not only for releasing carbon dioxide gas when the first pressure is abnormal, but also for filling carbon dioxide gas into the first space S1 before use or after use. It can also be used when removing carbon dioxide from S1.
　連通管５３は、一端が、第１容器本体部５１ａの第１連通継手部６３ａに取り付けられ、他端が、第２容器本体部５２ａの第２連通継手部７３ａに取り付けられる。これにより、第１容器部５１の第１空間部Ｓ１と、第２容器部５２の第２空間部Ｓ２とが連通し、炭酸ガスの第２空間部Ｓ２から第１空間部Ｓ１への流入が可能となる。
　また、連通管５３には、逆止機能を有する減圧弁５３ａが設けられている。このとき、必要に応じて、連通管５３には圧力計が設けられていてもよい。
　これにより、連通管５３においては、減圧弁３ａが設けられているので、炭酸ガスの流通量を制限することが可能となっている。
　また、連通管５３においては、減圧弁３ａが逆止機能を有するので、炭酸ガスが、第１空間部Ｓ１から第２空間部Ｓ２に流れ込み、第１圧力や第２圧力が安定しない状況が生じることを防止することができる。 One end of the communicating pipe 53 is attached to the first communicating joint portion 63a of the first container body portion 51a, and the other end is attached to the second communicating joint portion 73a of the second container body portion 52a. As a result, the first space portion S1 of the first container portion 51 and the second space portion S2 of the second container portion 52 are communicated with each other, and the inflow of carbon dioxide gas from the second space portion S2 into the first space portion S1 is prevented. It becomes possible.
Further, the communication pipe 53 is provided with a pressure reducing valve 53a having a check function. At this time, the communication pipe 53 may be provided with a pressure gauge, if necessary.
Since the communication pipe 53 is provided with the pressure reducing valve 3a, it is possible to limit the flow rate of the carbon dioxide gas.
Further, in the communication pipe 53, the pressure reducing valve 3a has a check function, so carbon dioxide gas flows from the first space S1 into the second space S2, causing a situation in which the first pressure and the second pressure are not stable. can be prevented.
　これらのことにより、連通管３においては、逆止弁３ｂにより炭酸ガスが一方向に流通し、且つ、流量が制限されることになるので、第２空間部Ｓ２における第２圧力が第１空間部Ｓ１における第１圧力よりも大きくなるように調整することが可能となっている。
　なお、減圧弁５３ａは、炭酸ガスの流通を制限することにより圧力を調整することの他、連通管５３を全開にすることも全閉にすることも可能となっている。
　また、減圧弁５３ａは、上述したことと同様に、公知のものを適宜採用することができる。 As a result, in the communication pipe 3, the check valve 3b causes the carbon dioxide gas to flow in one direction and the flow rate to be restricted. It can be adjusted to be greater than the first pressure in section S1.
The pressure reducing valve 53a is capable of adjusting the pressure by restricting the flow of carbon dioxide gas, and also allowing the communication pipe 53 to be fully opened or fully closed.
Further, as for the pressure reducing valve 53a, a well-known one can be appropriately adopted as described above.
　第２容器部２においては、外部から炭酸ガスを注入するための炭酸ガス継手部７３ｂが設けられている。
　炭酸ガス継手部７３ｂは、例えば、ガスボンベ等から炭酸ガスを注入する際に用いられる継手である。
　炭酸ガス継手部７３ｂには、図示しない第２開閉弁が内蔵されている。
　例えば、炭酸ガス継手部７３ｂにおいては、第２開閉弁を開放し、且つ、ガスボンベの管を炭酸ガス継手部７３ｂに取り付けることにより、当該ガスボンベから炭酸ガス継手部７３ｂを介して、第２空間部Ｓ２に炭酸ガスを注入することができる。
　また、炭酸ガスの注入を行わない場合は、第２開閉弁は、閉鎖される。 The second container portion 2 is provided with a carbon dioxide joint portion 73b for injecting carbon dioxide gas from the outside.
The carbon dioxide joint portion 73b is a joint used, for example, when injecting carbon dioxide gas from a gas cylinder or the like.
A second on-off valve (not shown) is incorporated in the carbon dioxide joint 73b.
For example, in the carbon dioxide joint portion 73b, by opening the second on-off valve and attaching a pipe of a gas cylinder to the carbon dioxide joint portion 73b, the gas cylinder is connected to the second space portion via the carbon dioxide joint portion 73b. Carbon dioxide can be injected into S2.
Moreover, when not injecting carbon dioxide gas, the second on-off valve is closed.
　このように、炭酸水用卓上ポット１０１においては、炭酸ガスの出し入れ等を、対応する各蓋部の継手部で行うことができるので、容器本体部の構造をシンプルなものとすることができる。
　なお、炭酸水用卓上ポット１０１における第１空間部Ｓ１の第１圧力及び第２空間部Ｓ２の第２圧力の関係については、上述した第１実施形態に係る炭酸水用卓上ポット１００の第１圧力及び第２圧力と同じであるので説明を省略する。 As described above, in the tabletop pot for carbonated water 101, carbon dioxide can be taken in and out at the corresponding joints of the respective lids, so that the structure of the container main body can be simplified.
Regarding the relationship between the first pressure in the first space S1 and the second pressure in the second space S2 in the tabletop pot for carbonated water 101, the first pressure in the tabletop pot for carbonated water 100 according to the above-described first embodiment Since it is the same as the pressure and the second pressure, the explanation is omitted.
　炭酸水用卓上ポット１０１においては、第１圧力が維持されるので、経時的に炭酸水Ｗの炭酸ガスが抜けることを抑制することができる。また、一定量の炭酸ガスを含む炭酸水Ｗを、一定の勢いで注出させることが可能となる。
　また、第２容器部５２に貯留された炭酸ガスを利用して、第１圧力の低下分を補充できるので、コンパクトな構造とすることができ、持ち運びも極めて容易となる。 Since the first pressure is maintained in the tabletop pot for carbonated water 101, it is possible to suppress the release of carbon dioxide from the carbonated water W over time. Further, it becomes possible to pour out the carbonated water W containing a certain amount of carbon dioxide gas at a certain force.
In addition, since the carbon dioxide stored in the second container portion 52 can be used to replenish the first pressure drop, the structure can be made compact and the portability is extremely easy.
　炭酸水用卓上ポット１０１において、炭酸水Ｗが貯留されていない場合の第１空間部Ｓ１の容積は、コンパクトでありながら、十分な量の炭酸水Ｗを貯留するという観点から、３５０～３５００ｃｍ３であることが好ましい。
　また、第２空間部Ｓ２の容積は、コンパクトでありながら、十分な量の炭酸水Ｗが注出された場合であっても第１圧力を維持するための十分な炭酸ガスを貯留するという観点から、４９０～５６００ｃｍ３であることが好ましい。 In the tabletop pot for carbonated water 101, the volume of the first space S1 when carbonated water W is not stored is 350 to 3500 cm 3 from the viewpoint of storing a sufficient amount of carbonated water W while being compact. is preferred.
In addition, the volume of the second space S2 is compact, but from the viewpoint of storing enough carbon dioxide gas to maintain the first pressure even when a sufficient amount of carbonated water W is poured out. Therefore, it is preferably 490 to 5600 cm 3 .
　炭酸水用卓上ポット１００において、注出ノズル部５４は、流通管５５（詳しくは外側流通管５５ａ）の先端に設けられる。
　具体的には、注出ノズル部５４は、炭酸水Ｗを注出するノズル口部５４ａと、炭酸水Ｗの流路に設けられた止め栓（図示しない）と、該止め栓を開閉させるための注出レバー５４ｂとを有する。 In the tabletop pot for carbonated water 100, the pouring nozzle portion 54 is provided at the tip of the flow pipe 55 (specifically, the outer flow pipe 55a).
Specifically, the pouring nozzle portion 54 includes a nozzle mouth portion 54a for pouring out the carbonated water W, a stopcock (not shown) provided in the flow path of the carbonated water W, and a stopcock for opening and closing the stopcock. and a pouring lever 54b.
　注出ノズル部５４においては、第１空間部Ｓ１の圧力により、流通管５５内の炭酸水Ｗが、注出ノズル部５４側に付勢されているので、注出レバー部５４ｂを操作して、止め栓を開放することにより、ノズル口部５４ａから炭酸水Ｗが注出されるようになっている。
　また、注出レバー部５４ｂを操作して、止め栓で閉鎖することにより、ノズル口部５４ａからの炭酸水Ｗの注出は停止される。
　なお、炭酸水用卓上ポット１０１における炭酸水Ｗ及び炭酸ガスの充填方法、及び、炭酸水Ｗの注出方法については、第１実施形態に係る炭酸水用卓上ポット１００における炭酸水Ｗ及び炭酸ガスの充填方法、及び、炭酸水Ｗの注出方法と同様に行うことができる。 In the pouring nozzle portion 54, the carbonated water W in the flow pipe 55 is urged toward the pouring nozzle portion 54 by the pressure of the first space S1. The carbonated water W is poured out from the nozzle opening 54a by opening the stopcock.
Further, by operating the pouring lever portion 54b and closing it with a stopcock, the pouring of the carbonated water W from the nozzle mouth portion 54a is stopped.
