【発明の属する技術分野】
本発明は炭酸飲料抽出器、殊に内容積が１０cc程度の炭酸ガスカートリッジのガス圧を利用して容器内の炭酸飲料を、所謂ガス抜け作用を起こさせずに、外部へ抽出する型式のものの改良に関する。
【０００２】
【従来の技術】
本件出願人は先に特開平７−３５９５４号で炭酸ガスカートリッジが着脱自在のキャップを容器に装着して炭酸飲料を炭酸ガスの圧力で容器外へ抽出する型式の炭酸飲料抽出器を提案している。
また、本件出願人は同じく特願平１０−２１１７３６号で、炭酸飲料を炭酸ガスの圧力で容器外へ抽出する型式の炭酸飲料抽出器において、不使用時にガス供給部を容器から取り外すことにより、容器を倒した状態で家庭の冷蔵庫にも納められるようにした発明を提案している。
炭酸飲料抽出器は飲料抽出時の発泡を防ぐために、抽出圧力を制御する減圧手段を必要とする。一般的には管路の長さを適当に取り、その管路抵抗により減圧するか、ＵＳＰＡＴ２８９９１７０のように減圧器を構成して減圧制御し、抽出を行っている。上記のいずれの場合にも、発泡を防ぐための減圧手段が設けられている。
【０００３】
【発明が解決しようとする課題】
飲料抽出時の発泡防止を管路抵抗による減圧でする場合、構造が簡単になるので制御は確実であるが、その構造から飲料通路を確実に洗浄することは難しくなってしまう。
また、減圧器を使用する場合、この減圧器は分離できる構造となっているため、飲料通路の洗浄は確実に行うことができるが、構造上飲料通路の隙間は非常に狭く、流量を正確に制御するのが大変困難となっている。
本発明は、減圧抽出部に管状の流路を採用して制御の容易さでは管路型と同様にし、更に減圧抽出部に分解構成を採用して洗浄の可能性の点で減圧器型と同様にして、これらの課題を解決することを意図するものである。
【０００４】
【課題を解決するための手段】
本発明にかかる炭酸飲料抽出器は飲料抽出部とガス供給部を備えている。該飲料抽出部はキャップ、サイホン管、開閉弁及び抽出口を有している。該キャップは容器の開口部に対する取付部、逆止弁付きガス導入路及び飲料導出路を有している。該サイホン管は上端部が該飲料導出路に導結されると共に管路型でかつ分解型の減圧抽出部を備えている。
該減圧抽出部はケースと中子を有している。該ケースは閉環状の内壁面を備え、軸線上の一端に開放口を有し、他端が端壁で閉塞され、該端壁に通孔が開口し、該開放口側で周壁の一部が軸線方向へ突き出た一対の耳を備え、該耳にだぼ穴が穿たれている。また該中子は該ケースの内壁面に密嵌する外壁面を有し、該開放口を通して該ケースに嵌合され、該ケースとの嵌合時に該耳を弾発して該だぼ穴に嵌合するだぼを備えている。そして、該ケースの内壁面と該中子の該外壁面の少なくとも一方に螺旋状の溝が形成され、該溝は該ケースと該中子を密嵌した状態でその両端が該ケースの外部と連通して流体通路を現出するようになっている。
該開閉弁は該飲料導出路内の弁座と弁体を有している。該抽出口は一端が該キャップ外に開口し、他端が該飲料導出路と該弁座の下流側で連通している。
そして、該ガス供給部はそのガス流出口が該キャップの該ガス導入路と導通するようになっている。
【０００５】
本発明抽出器の飲料抽出部のサイホン管を炭酸飲料が入った容器の開口部を通してこの容器に入れ、キャップを開口部にその取付部で取付ける。一般的にこの取付部はねじとなっているが、クリック機構等のワンタッチ型でもよい。
【０００６】
また、ガス供給部の取付部にガスが充填されたガスカートリッジを取付ける。このカートリッジの容積は１０cc程度のもので、ガスはＣＯ₂ガスが一般的である。このカートリッジは取付完了時点で開栓部により開栓される。この開栓部は、カートリッジが封板で密封される型式の場合は穿針型で、再充填型封止機構型の場合は押し棒型となる。
【０００７】
開栓されたカートリッジから高圧ガスが流出し、ガス取出部を通って減圧部で減圧され、ガス流出口へ流れる。このガス流出口に自閉弁を配設しておけば、ガスはこの自閉弁により流出を阻止されるので、ガス供給部と飲料抽出部を分離型とすることもできる。
【０００８】
容器内の圧力がこの減圧部で減圧された圧力より低いときはガスがガス導入路を通って容器内に入り、炭酸飲料の表面を加圧する。
【０００９】
分離型の場合、ガス導入路に逆止弁を設けておけば、加圧時にガス流出口をガス導入路と分離した際に、容器内ガスの流出を防ぐ。また、ガス導入路の外端を蓋で閉塞するようにすると、異物の侵入を防げ、ガス抜け予防にもある程度役立つ。容器内の圧力と減圧部での圧力が均衡するとカートリッジからのガスの流出は止む。
【００１０】
炭酸飲料を取出したいときは、抽出口に容れ物、例えばコップを当てがい開閉弁を開放する。抽出口にノズルを接続した場合はこのノズルの先端に容れ物を当てがう。開閉弁の操作には例えばレバー、押し釦又はネジ棒が採用される。開閉弁の開放により飲料導出路が開通する。そのため、容器内ガスの圧力で表面を圧下された炭酸飲料は管路型でかつ分解型の減圧抽出部を通ってサイホン管に流れる。
【００１１】
この場合、螺旋状の溝が炭酸飲料の通路となり、この溝はケースと中子を嵌合するだけで両者の内外壁面間に形成されるので、流路断面は常に一定となり、正確な流量制御が可能となる。
この減圧抽出部を通った炭酸飲料はサイホン管の内部を上昇し、飲料導出路を通って抽出口から容れ物に抽出される。
開閉弁を閉じれば、飲料導出路が閉止されて飲料の抽出が止む。
【００１２】
飲料の抽出により容器内の圧力がガス供給部の減圧部内の圧力より低くなると、減圧部よりガスがガス導入路を通って容器内に流入する。そして、この流入は両圧力がバランスするまで続く。
【００１３】
飲料の抽出を終えて容器が空になった場合は、飲料抽出部の減圧抽出部を分解し、これを洗浄すれば衛生的となる。
【００１４】
飲料を満たした容器を用意してガス供給部と飲料抽出部をこの容器に取付ければ、前回と同様にして炭酸飲料を抽出できる。
【００１５】
該ケースは軸線上の一端に開放口を有し、他端が端壁で閉塞され、該端壁に通孔が開口し、該中子は該開放口を通して該ケースに嵌合されているので、中子をケースの一端の開放口からこのケースに嵌合するだけで容器内から減圧抽出部を通ってサイホン管に通じる飲料の通路が開通できる。
【００１６】
該ケースは該開放口側で周壁の一部が軸線方向へ突き出た一対の耳を備え、該耳にだぼ穴が穿たれ、該中子は該ケースとの嵌合時に該耳を弾発して該だぼ穴に嵌合するだぼを備えているので、中子とケースはだぼとだぼ穴の弾発係合により一体化され、供用中に両者が離脱することがない。
【００１７】
該ケースと該中子は、該内壁面と外壁面が両者を嵌合する方向に向かって縮径するテーパー面に形成され、かつ両者の嵌合時点で相対する該ケースの該端壁と該中子の端面間に隙間が形成されるようになっていてもよい。
この場合、減圧抽出部の作動中、炭酸飲料の入口と出口間に発生する圧力差が中子をケース内へ押し込むので、両テーパー面が圧着して隙間が発生せず、正確な流量制御が可能となる。
【００１８】
該ケースと該中子の少なくとも一方が弾性材で構成されていてもよい。
この場合、該ケースの該内壁面と該中子の該外壁面同士の密着性が高まり、流量制御が一層正確となる。
【００１９】
該中子は該ケースに対する嵌合方向と反対側の端部にフランジを備え、該フランジは該中子及び該だぼの両軸線を含む平面上に該耳と係合するための切欠を備えていてもよい。
この場合、中子の挿脱をこのフランジに指をかけて行え、中子のだぼとケースのだぼ穴の係合も耳をフランジの切欠に嵌合するだけで行える。
【００２０】
該ケースはシール材を介して該開放口を気密に閉塞自在の蓋を有し、該溝は該中子に設けられ、該溝の一端は該ケースの該通孔に連通し、他端は該蓋の周壁の内面に設けられた環状溝に連通し、該環状溝は該周壁に貫設した通孔と連通していてもよい。
この場合、中子をケースに入れて蓋で押さえるだけで、中子とケースの相対位置関係は簡単に一定に保たれて流体通路も確保され、特別の位置合わせは不要である。
【００２１】
【発明実施の形態】
１は飲料抽出部、２はガス供給部である。
飲料抽出部１はキャップ３、サイホン管４、開閉弁５及び抽出口６を有している。
【００２２】
キャップ３は容器７の開口部８に対する取付部９、弾性の逆止弁１０付きガス導入路１１及び飲料導出路１２を有している。このサイホン管４は上端部が飲料導出路１２に導結され、下端に管路型でかつ分離型の減圧抽出部１３を備えている。飲料導出路１２はキャップ３の頂部１４に、その内外に貫通して設けられている。
【００２３】
減圧抽出部１３はケース５１と中子５２を有し、ケース５１は円筒状の内壁面５３を備え、中子５２はケース５１の内壁面５３に密嵌する外壁面５４を有している。そして、ケース５１の内壁面５３と中子５２の外壁面５４の少なくとも一方、図示の場合は中子５２の外壁面５４、に螺旋状の溝５５が形成される。この溝５５はケース５１と中子５２を密嵌した状態でその両端がケース５１の外部と連通して流体通路５６を現出するようになっている。
【００２４】
開閉弁５は飲料導出路１２内の弁座１５と弁体１６を有している。弁体１６はキャップ３から上方へ突出し、ピン１７によってレバー１８に連結される。このレバー１８は弁体１６を閉位置又は開位置に保つ各別の保持面１９と２０を備えている。また弁体１６とキャップ３の間に弁体１６を閉位置に戻そうとするスプリング２１が介装される。
【００２５】
抽出口６は一端がキャップ３外に開口してノズル２２が接続され、他端が飲料導出路１２と弁座１５の下流側で連通している。
【００２６】
ガス供給部２は本体３１、ガスカートリッジ３２の取付部３３、開栓部３４、ガス取出部３５、減圧部３６及びガス流出口３７を有する通常型で、このガス流出口３７に自閉弁３８が配設されている。この自閉弁３８はガス供給部２と飲料抽出部１が分離型の場合、分離時にガス流出口３７を常に閉止するようになっている。
そして、このガス供給部２はガス流出口３７がキャップ３のガス導入路１１と導通するようになっている。
【００２７】
図示の抽出器は、減圧抽出部１３を備えたサイホン管４を炭酸飲料の入った容器７に入れて、飲料抽出部１のキャップ３をこの容器７の開口部８に取付部９で気密に取付ける。図示の例では、このキャップ３は環状シール部材３９を介して開口部８に取付けられ、ガスシールがなされる。
【００２８】
ガス導入路１１はキャップ３の頂部１４に貫設され、キャップ３内では筒部４１で囲まれている。この筒部４１の外周に下端を閉塞した弾性の逆止弁１０が圧嵌している。この逆止弁１０は下端に割れ目４２が形成されており、ガス導入路１１に外部から規定された圧力がかかるとこの割れ目４２が開いて外部から容器７の内部へガスを流し、圧力がこの規定値以下になるとこの割れ目４２が閉じて容器７の内部のガスが外部へ流出するのを阻止する。
【００２９】
この割れ目４２の替りに、筒部４１の側面に孔をあけて下端を閉塞し、弾性筒体をこの筒部４１に嵌め込んでこの孔を塞ぐようにしてもよい。
【００３０】
次に、ガス供給部２ではガスカートリッジ３２をその取付部３３に取付ける。ガスカートリッジ３２は開栓部３４で開栓され、圧力ガスがガス取出部３５に出て減圧部３６で減圧される。減圧されたガスがガス流出口３７を通って飲料抽出部１のガス導入路１１に入り、容器７に流れ込む。そして、容器７内の圧力と減圧されたガスの圧力が均衡するとガスの流れは停止する。
【００３１】
容器７内の炭酸飲料はその液面にこのガス圧がかかるので、レバー１８で弁体１６を弁座１５から離別させれば、容器７内の炭酸飲料はガス圧により減圧抽出部１３内を均一に流れ、サイホン管４内を昇流して抽出口６を通り、ノズル２２から抽出される。
レバー１８を放せばスプリング２１により弁体１６が弁座１５に着座し、飲料の抽出は停止する。
減圧抽出部１３では螺旋状の溝５５が炭酸飲料を通す流体通路５６を形成するので、流路断面は常に一定となり、正確な流量制御が可能となる。
【００３２】
ケース５１は軸線上の一端に開放口５７を有し、他端が端壁５８で閉塞され、この端壁５８に通孔５９が開口し、中子５２はこの開放口５７を通してケース５１に嵌合されている。中子５２をケース５１の一端の開放口５７からこのケース５１に嵌合するだけで容器７内から減圧抽出部１３を通ってサイホン管４に通じる飲料の通路が開通できる。
【００３３】
ケース５１は開放口５７側で周壁の一部が軸線方向へ突き出た一対の耳６５を備え、これらの耳６５にだぼ穴６６が穿たれ、中子５２はこのケース５１との嵌合時に耳６５を弾発してだぼ穴６６に嵌合するだぼ６７を備えている。
中子５２とケース５１はだぼ６７とだぼ穴６６の弾発係合により一体化されるので、供用中に両者が離脱することがない。
【００３４】
図３から図８は減圧抽出部の別の形態を示してある。ケース５１と中子５２は、ケース５１の内壁面５３と中子５２の外壁面５４が、両者を嵌合する方向に向かって角度θで縮径して行くテーパー面６１及び６２に形成され、かつ両者の嵌合時点で相対するケース５１の端壁５８と中子５２の端面６３間に隙間６４が形成されるようになっている。
こうすると、減圧抽出部１３の作動中、炭酸飲料の入口と出口間に発生する圧力差が中子５２をケース５１内へ押し込むので、両テーパー面６１と６２が圧着して隙間が発生せず、正確な流量制御が可能となる。
【００３５】
ケース５１と中子５２の少なくとも一方が弾性材で構成されている。
こうすると、ケース５１の内壁面５３と中子５２の外壁面５４同士の密着性が高まり、流量制御が正確となる。
【００３６】
中子５２は端面６３と反対側の端部にフランジ６８を備え、このフランジ６８は中子５２及びだぼ６７の両軸線を含む平面上に耳６５と係合するための切欠６９を備えている。
こうすると、中子５２の挿脱をこのフランジ６８に指をかけて行え、中子５２のだぼ６７とケース５１のだぼ穴６６の弾発係合も耳６５をフランジ６８の切欠６９に嵌合するだけで行える。
【００３７】
図９は減圧抽出部１３の更に別の形態を示してある。ケース５１はシール材７１を介して開放口５７を気密に閉塞自在の蓋７２を有し、溝５５は中子５２に設けられ、この溝５５の一端はケース５１の通孔５９に連通し、他端は蓋７２の周壁７３の内面に設けられた環状溝７４に連通し、この環状溝７４は周壁７３に貫設した通孔７５と連通している。
こうすると、中子５２をケース５１に入れて蓋７２で押さえるだけで、中子５２とケース５１の相対位置関係は簡単に一定に保たれて流体通路５６も確保され、特別の位置合わせは不要である。
【００３８】

BACKGROUND OF THE INVENTION
The present invention relates to a carbonated beverage extractor, in particular, a type that extracts the carbonated beverage in a container to the outside without causing a so-called gas escape action using the gas pressure of a carbon dioxide cartridge having an internal volume of about 10 cc. Regarding improvement.
[0002]
[Prior art]
The present applicant has previously proposed a carbonated beverage extractor of the type disclosed in Japanese Patent Application Laid-Open No. 7-35954, in which a cap with a detachable carbon dioxide cartridge is attached to a container and carbonated beverage is extracted out of the container by the pressure of carbon dioxide gas. Yes.
Further, the present applicant is also Japanese Patent Application No. 10-211736, and in a carbonated beverage extractor of a type that extracts carbonated beverages outside the container with the pressure of carbon dioxide gas, by removing the gas supply unit from the container when not in use, It proposes an invention that can be stored in a household refrigerator with the container down.
Carbonated beverage extractors require decompression means for controlling the extraction pressure in order to prevent foaming during beverage extraction. In general, the length of the pipe line is taken appropriately and the pressure is reduced by the pipe resistance, or extraction is performed by controlling the pressure reduction by configuring a pressure reducer like US PAT 2899170. In any of the above cases, a decompression means for preventing foaming is provided.
[0003]
[Problems to be solved by the invention]
When the prevention of foaming at the time of beverage extraction is performed by reducing the pressure by pipe resistance, the structure becomes simple and the control is reliable, but it is difficult to reliably wash the beverage passage from the structure.
In addition, when using a pressure reducer, the pressure reducer has a structure that can be separated, so that the beverage passage can be reliably cleaned, but the gap in the beverage passage is structurally very narrow, and the flow rate is accurate. It is very difficult to control.
The present invention adopts a tubular flow path in the decompression extraction unit and is similar to the pipe type in terms of ease of control, and further adopts a disassembly configuration in the decompression extraction unit to reduce the possibility of cleaning. Similarly, it is intended to solve these problems.
[0004]
[Means for Solving the Problems]
The carbonated beverage extractor according to the present invention includes a beverage extraction unit and a gas supply unit. The beverage extraction unit has a cap, a siphon tube, an on-off valve, and an extraction port. The cap has an attachment portion for the opening of the container, a gas introduction passage with a check valve, and a beverage outlet passage. The siphon tube has an upper end portion connected to the beverage outlet passage and a duct-type and decomposition-type decompression extraction portion.
The decompression extraction unit has a case and a core. The case has a closed annular inner wall surface, has an open port at one end on the axis , is closed at the other end by an end wall, has a through hole in the end wall, and is part of the peripheral wall on the open port side. Is provided with a pair of ears projecting in the axial direction, and a dowel hole is formed in the ear. In addition, the core has an outer wall surface that fits closely to the inner wall surface of the case, is fitted into the case through the opening, and is snapped into the dowel hole by repelling the ear when fitted to the case. It has a dowel. Then, a spiral groove is formed in at least one of the inner wall surface of the case and the outer wall surface of the core, and both ends of the groove are connected to the outside of the case in a state where the case and the core are closely fitted. The fluid passage is exposed in communication.
The on-off valve has a valve seat and a valve body in the beverage outlet path. One end of the extraction port opens outside the cap, and the other end communicates with the beverage outlet path on the downstream side of the valve seat.
The gas supply unit is configured such that the gas outlet is electrically connected to the gas introduction path of the cap.
[0005]
The siphon tube of the beverage extraction part of the extractor of the present invention is put into this container through the opening of the container containing the carbonated beverage, and the cap is attached to the opening by the attachment part. Generally, this attachment portion is a screw, but it may be a one-touch type such as a click mechanism.
[0006]
A gas cartridge filled with gas is attached to the mounting portion of the gas supply unit. The volume of this cartridge is about 10 cc, and the gas is generally CO ₂ gas. The cartridge is opened by the opening portion when the attachment is completed. The opening portion is a needle-piercing type in the case where the cartridge is sealed with a sealing plate, and a push-bar type in the case of a refill-type sealing mechanism type.
[0007]
High-pressure gas flows out from the opened cartridge, is decompressed by the decompression section through the gas extraction section, and flows to the gas outlet. If a self-closing valve is provided at the gas outlet, the gas is prevented from flowing out by the self-closing valve, so that the gas supply unit and the beverage extraction unit can be separated.
[0008]
When the pressure in the container is lower than the pressure reduced in the decompression section, gas enters the container through the gas introduction path and pressurizes the surface of the carbonated beverage.
[0009]
In the case of the separation type, if a check valve is provided in the gas introduction path, the outflow of the gas in the container is prevented when the gas outlet is separated from the gas introduction path during pressurization. Further, if the outer end of the gas introduction path is closed with a lid, it is possible to prevent foreign substances from entering and to some extent prevent gas leakage. When the pressure in the container and the pressure in the decompression section are balanced, the outflow of gas from the cartridge stops.
[0010]
When it is desired to take out the carbonated beverage, a container, for example, a cup is applied to the extraction port to open the on-off valve. When a nozzle is connected to the extraction port, the container is applied to the tip of this nozzle. For the operation of the on-off valve, for example, a lever, a push button or a screw rod is employed. The beverage outlet path is opened by opening the on-off valve. Therefore, the carbonated beverage whose surface has been reduced by the pressure of the gas in the container flows into the siphon tube through the duct-type and decomposition-type decompression extraction unit.
[0011]
In this case, the spiral groove becomes a carbonated beverage passage, and this groove is formed between the inner and outer wall surfaces just by fitting the case and core, so the cross section of the flow path is always constant and accurate flow control Is possible.
The carbonated beverage that has passed through the decompression extraction unit ascends inside the siphon tube, and is extracted from the extraction port into a container through the beverage outlet path.
If the on-off valve is closed, the beverage outlet path is closed and the beverage extraction stops.
[0012]
When the pressure in the container becomes lower than the pressure in the decompression unit of the gas supply unit due to the extraction of the beverage, the gas flows from the decompression unit through the gas introduction path into the container. This inflow continues until both pressures are balanced.
[0013]
When the container is emptied after the extraction of the beverage, the decompression extraction unit of the beverage extraction unit is disassembled and washed to be sanitary.
[0014]
If a container filled with a beverage is prepared and a gas supply unit and a beverage extraction unit are attached to the container, a carbonated beverage can be extracted in the same manner as the previous time.
[0015]
The case has an open mouth at one end of the axis, the other end is closed by an end wall, a through hole is opened to the end wall, the tang is being fitted to the casing through the open mouth Runode By simply fitting the core into the case from the opening at one end of the case, a beverage passage that leads from the container to the siphon tube through the reduced pressure extraction unit can be opened.
[001 6 ]
The case has a pair of ears with a part of the peripheral wall protruding in the axial direction on the open mouth side, the ear has a dowel hole, and the core repels the ear when fitted to the case. Since the dowel hole is provided in the dowel hole, the core and the case are integrated by the elastic engagement of the dowel and dowel hole, so that they do not come off during service.
[001 7 ]
The case and the core are formed in a tapered surface in which the inner wall surface and the outer wall surface are reduced in diameter in a direction in which the two are fitted together, and the end wall of the case and the opposing wall at the time when the two are fitted together A gap may be formed between the end faces of the core.
In this case, the pressure difference generated between the carbonated beverage inlet and outlet during operation of the vacuum extraction unit pushes the core into the case. It becomes possible.
[001 8 ]
At least one of the case and the core may be made of an elastic material.
In this case, the adhesion between the inner wall surface of the case and the outer wall surface of the core is enhanced, and the flow rate control becomes more accurate.
[0019]
The core includes a flange at an end opposite to the fitting direction with respect to the case, and the flange includes a notch for engaging the ear on a plane including both the core and the dowel axis. It may be.
In this case, the core can be inserted and removed by placing a finger on the flange, and the core dowel and the case dowel hole can be engaged simply by fitting the ear into the notch of the flange.
[0020]
The case has a lid that is airtightly closing the opening through a sealing material, the groove is provided in the core, one end of the groove communicates with the through hole of the case, and the other end The annular groove may be communicated with an annular groove provided on the inner surface of the peripheral wall of the lid, and the annular groove may be communicated with a through-hole penetrating the peripheral wall.
In this case, simply by placing the core in the case and pressing it with the lid, the relative positional relationship between the core and the case is easily maintained constant, a fluid passage is secured, and no special alignment is required.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
1 is a drink extraction part, 2 is a gas supply part.
The beverage extraction unit 1 has a cap 3, a siphon tube 4, an on-off valve 5 and an extraction port 6.
