関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a liquid container in which a mouth portion having a diameter smaller than the maximum body diameter of the container body is connected to the upper part of the container body in a case, and a liquid container in the liquid container. This invention relates to a liquid storage container equipped with an air pump, which is equipped with an air pump that sends liquid out of the case.
この種の液体容器(2)の−例である魔法瓶としては、

知の何れのものも、例えば、第28図で示すように次の
[1]、[II]で記載の構成を有するものであった。An example of this type of liquid container (2) is a thermos flask.
There have been various types (for example, Utility Model Act 58-17560)
Publication No. 58-17559, Publication No. 17559, Publication No. 17559, Publication No. 17559-
No. 47091, etc.), but all of these known devices have the configurations described in the following [1] and [II], as shown in FIG. 28, for example.
[1] 液体容器(2)の口部(2b)開口高さ位置
よりも高い位置に前記空気ポンプ(P)の本体を配設す
る。[1] The main body of the air pump (P) is arranged at a position higher than the opening height of the mouth (2b) of the liquid container (2).
[n] 前記空気ポンプ(P)から液体容器(2)へ
の給気通路(D)を、前記ケース(7)内において空気
ポンプ(P)のポンプ室(12)の下部相当位置から導
き出す状態で形成する。[n] A state in which the air supply passage (D) from the air pump (P) to the liquid container (2) is led out from a position corresponding to the lower part of the pump chamber (12) of the air pump (P) in the case (7). to form.
このような従来魔法瓶では、空気ポンプ(P)の本体が
液体容器の口部よりも上方に大きく突出して位置するた
め、これに伴って重心位置が高くて安定性が悪くなるば
かりでなく、嵩高くなり易い。殊に、空気ポンプ(1’
)の操作具が該空気ポンプ(P)の上部に設けられてい
る場合には、ポンプ操作が行ないにくくなる不便さかあ
る。しかも萬か−、前記空気ポンプ(P)のポンプ室(
12)内に外部の水又は他物が入り込むと、これが前記
給気通路(D)を通して液体容器(2)内に流入し易い
欠点があった。In such conventional thermos flasks, the main body of the air pump (P) is positioned to protrude significantly above the mouth of the liquid container, which not only causes the center of gravity to be high, resulting in poor stability, but also bulkiness. It can easily become expensive. In particular, the air pump (1'
) is provided on the top of the air pump (P), there is an inconvenience that it becomes difficult to operate the pump. Moreover, the pump chamber of the air pump (P) (
12) If outside water or other matter enters the liquid container, there is a drawback that it tends to flow into the liquid container (2) through the air supply passageway (D).
また、上述のような魔法瓶のみならず、液体容器の口部
を最大胴径部よりも小径に構成してある霧吹器において
も、容器の口を通る上下下方姿勢の吸上管の、容器口か
ら上方に突出する上部位置にポンプ装置全体の嵩を小に
する上でかくあるべき当然の常識として用いられてきた
ようである。In addition, not only the above-mentioned thermos bottle but also a sprayer in which the opening of the liquid container is configured to have a smaller diameter than the maximum body diameter, the container opening of the suction pipe in a vertically downward position passing through the opening of the container It seems that the upper part of the pump protrudes upward from the top of the pump as a common sense idea that it should be placed in order to reduce the bulk of the pump device as a whole.
本発明は、上述の従来欠点を構成部材の合理的な配置改
良をもって改善する点に目的を有する。It is an object of the present invention to overcome the above-mentioned conventional drawbacks by improving the rational arrangement of the components.
かかる目的を達成するために講じられた本発明による空
気ポンプ付液体収容容器の特徴構成は、前記口部近くの
容器外周面と前記ケースの内周面との間に形成させた空
間内に、前記空気ポンプを大きく入り込み位置させると
ともに、前記空気ポンプから液体容器内への給気通路を
、前記ケース内において、前記空気ポンプのポンプ室上
部から導き出す状態で形成した点にある。A characteristic configuration of the liquid storage container with an air pump according to the present invention, which was taken to achieve such an object, is that in a space formed between the outer circumferential surface of the container near the mouth and the inner circumferential surface of the case, The air pump is placed in a large position, and an air supply passage from the air pump to the liquid container is formed in the case so as to lead out from the upper part of the pump chamber of the air pump.
上記特徴構成による作用効果は次の通りである。The effects of the above characteristic configuration are as follows.
つまり、液体容器の形状について考察すると、容器の口
部面積が容器全体の最大胴径部と等しい場合には、密閉
用開閉蓋も大きくなって全体的に取扱いが不便となり易
い面があり、また、容器内外を断熱する場合には、容器
の口部を極力小さくして、この口部に装着される栓体を
介しての熱の授受を少なくすることが有利となる場合が
ある。更に、容器の口部が上下方向に高さのある場合で
は、栓体と容器との接触面の内外方向長さを大にして、
密封性を良好にする又は断熱容器において栓体を介して
の熱の授受を抑制することができる利点がある。In other words, when considering the shape of a liquid container, if the opening area of the container is equal to the maximum body diameter of the entire container, the opening/closing lid for sealing will also become large, which tends to make handling the whole thing inconvenient. When insulating the inside and outside of a container, it may be advantageous to make the mouth of the container as small as possible to reduce the transfer of heat through the stopper attached to the mouth. Furthermore, if the mouth of the container is high in the vertical direction, the length of the contact surface between the stopper and the container in the internal and external directions is increased.
There is an advantage that the sealing performance can be improved or that heat transfer through the stopper can be suppressed in a heat-insulating container.
本発明は、上述のような不都合を解決するために、或い
は、要求機能を充足するために採られている容器の独特
な口絞り形状に着目して、この独特形状故に存在する空
間、つまり、前記口部近くの容器外周面とケース内周面
との間に存在する比較的大きな肩部空間を利用して空気
ポンプを大きく入り込み配設したことにより、従来に比
して嵩低く構成することができるばかりでなく、重心位
置を低くして安定性の向上を図ることができる。しかも
、前記空気ポンプから液体容器内への給気通路がケース
内において液体容器を貫通させない状態で、かつ、空気
ポンプのポンプ室上部から導き出す状態で形成されてい
るから、給気通路がケース外を通して形成される場合に
生じる他物との接触に起因する破損或いは給気通路が液
体容器の口部に貫通形成される場合の製作面上での不利
益を回避することができるとともに、萬が−、前記ポン
プ室内に外部の水或いは他物等が入り込んだ場合でも、
これらが給気通路を通して液体容器内に流入することを
抑制することができ、衛生的な使用ができるに至った。In order to solve the above-mentioned inconveniences or to satisfy the required functions, the present invention focuses on the unique neck shape of the container, and the space that exists due to this unique shape, that is, By utilizing the relatively large shoulder space existing between the outer circumferential surface of the container near the mouth and the inner circumferential surface of the case, the air pump is disposed in a large space, resulting in a structure that is lower in bulk than before. Not only this, but also the center of gravity can be lowered to improve stability. Moreover, since the air supply passage from the air pump to the liquid container is formed in the case without penetrating the liquid container and led out from the upper part of the pump chamber of the air pump, the air supply passage is outside the case. It is possible to avoid damage caused by contact with other objects when the air supply passage is formed through the opening of the liquid container, or disadvantages in manufacturing when the air supply passage is formed through the opening of the liquid container. - Even if external water or other objects enter the pump chamber,
It is possible to prevent these from flowing into the liquid container through the air supply passage, making it possible to use the product in a sanitary manner.

If the air supply passage (D) is damaged due to contact with other objects that occurs when the air supply passage (D) is formed through the outside, the mouth (2) of the medium bottle (2)
b) It is possible to avoid disadvantages in manufacturing as in the case where the pump chamber (12) is formed through the pump chamber (12).
Even if external water or other substances enter the inside, it is possible to effectively prevent this from flowing into the medium bottle (2) through the air supply passage (D).

After closing the hook valve (22), the bellows (16)
) is compressed. The air pressurized by the bellows (16) is discharged into the medium bottle (2) through the air supply passage (D) and pressurizes the liquid level of the stored liquid. Thereby, the stored liquid is poured out of the case (7) via the inner stopper unit (C) and the liquid injection pipe (1).

2) By letting the steam inside the bottle escape to the outside through the air supply passage (D), it is possible to prevent unexpected pouring of the stored liquid from the injection pipe (1) due to an increase in vapor pressure inside the medium bottle (2). It is possible to prevent this from occurring.
