Abstract

<P>PROBLEM TO BE SOLVED: To inhibit a hand pump for dispensing the content from a storage container from carrying the open air, bacteria, dust, or the like with itself into the container, because nitrogen gas is sealed in the storage container and sealed storage is preferred for avoiding quality degradation due to oxidation in storage of drinking liquid such as alcohol. <P>SOLUTION: The inside of the pump is completely shut off from the open air by arranging bellows 6b, a float valve 8 and a relief valve 9 in a piston mechanism of the hand pump. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は容器から液体を汲み上げるための手押しポンプに関する。  The present invention relates to a hand pump for pumping liquid from a container.

酒などの飲用液の保存には酸化による品質劣化を防ぐため、保存容器内に窒素ガス等を封入し密閉保存することが望ましい。保存容器から直接コップなどの小容器に分注する際には手押しポンプなどが必要になるが、このポンプを使用することにより、外気や細菌、ちり、ほこり等を飲用液内に取り込んでしまう可能性が高い。  In order to prevent the deterioration of quality due to oxidation, it is desirable to store a liquid such as liquor in a storage container sealed with nitrogen gas. When dispensing directly from a storage container to a small container such as a cup, a hand pump is required, but by using this pump, outside air, bacteria, dust, dust, etc. can be taken into the drinking liquid. High nature.

従来の方法を図3、図4に示す。図において1は容器、2は内容液、3は窒素ガス等の封入されたガス、4は吐出管、5はシリンダー管体、6はピストン、7はピストン棒である。  A conventional method is shown in FIGS. In the figure, 1 is a container, 2 is a content liquid, 3 is a sealed gas such as nitrogen gas, 4 is a discharge pipe, 5 is a cylinder tube, 6 is a piston, and 7 is a piston rod.

図3の方式は封入ガス3の圧力を上げて吐出管4より必要量を押し出すものであるがこの方式では容器全体の高気密性が必要となる。しかし、伝統的容器である陶器製の甕などを使用する場合、高気密にすることに困難をともない、ガスの圧力を上げることによりガスの消費にムダを発生させるとともに容器の強度にも悪影響となる引っ張り応力を与えることになる。  The method shown in FIG. 3 increases the pressure of the sealed gas 3 and pushes out a necessary amount from the discharge pipe 4, but this method requires high airtightness of the entire container. However, when using a ceramic container such as a traditional container, it is difficult to achieve high airtightness, and increasing the gas pressure causes waste in gas consumption and adversely affects the strength of the container. Will be given a tensile stress.

図4の方式は容器1の中にポンプ機構(4〜7)を挿入し内容液2を押し出すものであるがこの方法では封入ガス3の圧力は大気圧程度に留めることが可能であるが、シリンダー管体5内のピストン6の上部は大気に開放されたままになる。また、ピストン6摺動部を完璧に水密にすることは困難で、内容液2はピストン6の上側に漏れ出てくる。また、ピストン摺動面を介して外部の細菌やちり、ほこり等を内容液に取り込んでしまう可能性がある。  The method of FIG. 4 inserts the pump mechanism (4-7) into the container 1 and pushes out the content liquid 2. In this method, the pressure of the sealed gas 3 can be kept at about atmospheric pressure. The upper part of the piston 6 in the cylinder tube 5 remains open to the atmosphere. Further, it is difficult to make the sliding portion of the piston 6 completely watertight, and the content liquid 2 leaks to the upper side of the piston 6. Moreover, there is a possibility that external bacteria, dust, dust and the like are taken into the content liquid through the piston sliding surface.

本発明は上記図4の方式によるポンプ機構の問題点を解決することを目的とする。  An object of the present invention is to solve the problems of the pump mechanism according to the method shown in FIG.

本発明は上記目的を達成するためにピストン部にジャバラ機構を使い、シリンダー管体端面を完全に密封し、シリンダー管体内部を外気から完全に遮断することを可能にしたものである。  In order to achieve the above object, the present invention uses a bellows mechanism in the piston portion, completely seals the end surface of the cylinder tube body, and makes it possible to completely block the inside of the cylinder tube body from the outside air.

上述したようにシリンダー管体内を外気から遮断することにより、内容液の酸化の防止、細菌やちり、ほこり等の進入の防止が可能となる。また、ピストンをシリンダー内壁面に摺動させず、内壁面との間に空隙を設けるので摺動抵抗が無くなる。  As described above, by blocking the inside of the cylinder tube from the outside air, it is possible to prevent the content liquid from being oxidized and prevent the entry of bacteria, dust, dust and the like. Further, since the piston is not slid on the inner wall surface of the cylinder and a gap is provided between the piston and the inner wall surface, the sliding resistance is eliminated.

以下、本発明の実施の形態を図1、図2に基づいて説明する。  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

図において6a、6b、6cはそれぞれピストン、ジャバラ、フランジであるがこれらは一体に構成され、接合部は完全に気密である。ピストン6aにはピストン棒7が接合している。ピストン棒7は中空でありピストン6aの中心の貫通孔に連通している。ピストン6aの下面にはフロート8が、ピストン棒7の上端にはリリーフ弁9がそれぞれ取付けてある。5はシリンダー管体である。10はピストン棒7のガイドリングであり11はシリンダーカバーである。フランジ6cはガイドリング10を介してシリンダーカバー11によりシリンダー管体5の端面に密着されている。シリンダー管体5の下部には吐出管4が、最下部にはフート弁12が付いている。吐出管4は容器外まで導かれていて管路にチェック弁13を設けてある。ポンプ機構は図中4〜13によって構成される。  In the figure, 6a, 6b, and 6c are a piston, bellows, and flange, respectively, but these are integrally formed, and the joint is completely airtight. A piston rod 7 is joined to the piston 6a. The piston rod 7 is hollow and communicates with a through hole at the center of the piston 6a. A float 8 is attached to the lower surface of the piston 6a, and a relief valve 9 is attached to the upper end of the piston rod 7. 5 is a cylinder tube. 10 is a guide ring of the piston rod 7, and 11 is a cylinder cover. The flange 6 c is in close contact with the end surface of the cylinder tube 5 by the cylinder cover 11 via the guide ring 10. A discharge pipe 4 is attached to the lower part of the cylinder tube 5 and a foot valve 12 is attached to the lowermost part. The discharge pipe 4 is led out of the container, and a check valve 13 is provided in the pipe line. A pump mechanism is comprised by 4-13 in the figure.

1は容器、2は内容液、3は容器内空間に満たされた窒素ガス等である。  1 is a container, 2 is a content liquid, and 3 is nitrogen gas filled in the space in the container.

以下、〔図1〕〔図2〕を用いて上記構成の動作を説明する。容器1内にポンプ機構4〜12を装着し、容器内空間に有った空気を排出し窒素ガス等3で置換する。この時点では、ガス圧をほぼ大気圧とするとシリンダー管体5内には空気が残っている。ここでピストン棒7を押下げると、シリンダー管体5内容積が減少した分の空気がピストン棒7内の中空路を通ってリリーフ弁9を押上げ大気中に放出される。次にピストン棒7を引上げるとリリーフ弁9は閉じ中空路を塞ぐため大気の管体内への侵入が防がれ、管体内容積の増加に応じ内容液がフート弁12を押上げて管体内に入る。このようにしてピストン棒7を上下に動かすことを繰り返すと、終には内容液2は管体内を上昇しピストン6aの下面まで達する。この時、内容液2の浮力によりフロート8が上がりピストン6aの下面に密着する。(ピストン6a下面とフロート8はフロート弁を構成する。)これにより管体内部は外気からピストン6aの下面で遮断される。  The operation of the above configuration will be described below with reference to FIG. 1 and FIG. The pump mechanisms 4 to 12 are mounted in the container 1, and the air in the container space is discharged and replaced with nitrogen gas or the like 3. At this time, if the gas pressure is almost atmospheric pressure, air remains in the cylinder tube 5. When the piston rod 7 is pushed down, the air corresponding to the reduced volume of the cylinder tube 5 is pushed through the hollow passage in the piston rod 7 and the relief valve 9 is pushed up and released into the atmosphere. Next, when the piston rod 7 is pulled up, the relief valve 9 is closed and the hollow passage is closed, so that the intrusion of the atmosphere into the tubular body is prevented, and the content liquid pushes up the foot valve 12 as the tubular body volume increases, and the tubular body. to go into. When the movement of the piston rod 7 up and down is repeated in this way, the content liquid 2 eventually rises in the tube and reaches the lower surface of the piston 6a. At this time, the float 8 rises due to the buoyancy of the content liquid 2 and comes into close contact with the lower surface of the piston 6a. (The lower surface of the piston 6a and the float 8 constitute a float valve.) As a result, the inside of the tubular body is blocked from the outside air by the lower surface of the piston 6a.

一旦この状態になった後ピストン棒7を押下げると、その圧力は直接内容液2に伝わり、管体内部の容積が減少した分量の内容液が吐出管4から吐出される。次にピストン棒7を引上げると管体内部の容積が増加した分量の内容液2が管体下端のフート弁12を押上げて管体内部に流入し吐出された分を補充する。以上のように、シリンダー管体5の内部はその上端面に密着したフランジ6c、ジャバラ6b、ピストン6a、フロート8により完全に外気と遮断された環境を実現でき、その環境のもとで内容液の汲出しが可能となる。  Once the piston rod 7 is pushed down after this state is reached, the pressure is directly transmitted to the content liquid 2 and the content liquid in an amount corresponding to the reduced volume inside the tube is discharged from the discharge pipe 4. Next, when the piston rod 7 is pulled up, the amount of the content liquid 2 whose volume is increased inside the tube pushes up the foot valve 12 at the lower end of the tube to replenish the amount discharged and discharged into the tube. As described above, the inside of the cylinder tube body 5 can realize an environment in which it is completely shut off from the outside air by the flange 6c, the bellows 6b, the piston 6a, and the float 8 that are in close contact with the upper end surface thereof, and the content liquid can be obtained in that environment. Can be pumped out.
