【考案の詳細な説明】 本考案は液体をコツプ等の容器に注出する際、容器の高
さに合せて注出口の位置を上下に移動できるようにした
エアーポットの改良に係るものである。[Detailed description of the invention] This invention relates to an improvement of an air pot that allows the position of the spout to be moved up and down according to the height of the container when pouring liquid into a container such as a pot. .

現在一般に市販に市販されているエアーポットは注出口
の位置が高いので、机に置いたコツプに注湯するときお
湯が飛散して危険であり、またコツプが注出口の下部位
置からずれていたりすると外部に流失することもあった
。Air pots that are currently on the market have spouts located high up, so when pouring hot water into a pot placed on a desk, hot water may scatter, creating a danger.Also, the spout may be displaced from the bottom of the spout. In some cases, it was washed away outside.

従って最近では注出口の位置を液体を受けるコツプの高
さに合せて上下動できるようにして上記欠点を解消しよ
うと試みられている。Therefore, attempts have recently been made to overcome the above-mentioned drawbacks by making the position of the spout movable up and down in accordance with the height of the tip that receives the liquid.

しかし液体を誘導する注出管を連続させて注出口を下方
位置まで延出させた場合には、サイフオン作用によりエ
アーポンプを押すと、手を離しても保温瓶内の液面が注
出口と同一高さに低下するまで注出を続けることになる
とともに、保温瓶内の蒸気圧が高くなると自然吐出現象
が生じとても危険性が高いものとなっていた。However, if the spout tube that guides the liquid is continuous and the spout is extended to the lower position, when the air pump is pushed by the siphon action, the liquid level in the thermos bottle will remain at the spout even if the hand is removed. In addition to having to continue dispensing until the temperature drops to the same level, as the vapor pressure inside the bottle increases, a spontaneous discharge phenomenon occurs, which is extremely dangerous.

そこで本考案は、注出口の位置を液体を受けるコツプ等
の容器の高さに合せて上下動できるポットでありながら
、自然吐出やサイフオン現象を無くした安全なエアーポ
ットを提供しようとするものである。Therefore, the present invention aims to provide a safe air pot that eliminates spontaneous discharge and siphon phenomenon, although the position of the spout can be moved up and down to match the height of the container such as a cup that receives liquid. be.

以下本考案の一実施例を図面に基づいて説明すれば、エ
アーポット１において、本体２内部には保温瓶３を装着

気を送り込むための蛇腹式エアーポンプ４が設けられて
いる。An embodiment of the present invention will be described below based on the drawings. In an air pot 1, a heat insulating bottle 3 is installed inside the main body 2, and compressed air is stored in the heat insulating bottle 3 in the upper lid body 5. A bellows type air pump 4 is provided for feeding the air.

貫通孔１３内に上下方向摺動自在に設けている。Then, the discharge hole 6 at the lower part of the air pump 4 is communicated with the ventilation hole 9 of the stopper 8 fitted into the mouth part 7 of the thermos bottle 3, and the air is connected through the valve 11 provided in the intake hole 10 at the upper part of the air pump 4. A pressurizing body 12 for pressing and moving the air pump 4 is provided in a through hole 13 of the lid body 5 so as to be slidable in the vertical direction.

１４は注出管であり、上記栓体８に一体的に設けられ、
その上部は本体２内部で略コの字形に屈曲し、下方に垂
下した端部１５の下端開口部は閉栓した状態で保温瓶３

定されている。14 is a pouring pipe, which is provided integrally with the stopper 8;
The upper part is bent into a substantially U-shape inside the main body 2, and the lower end opening of the end 15 that hangs downward is closed when the thermos bottle 3 is closed.
It is set at a position that is the same as or slightly higher than the top of the .

１６は略り字状に屈曲して下端が後述する注出体１８内

体のオーバーフローを無くすため両者の内径比率は注出
管１４を１とすれば連絡管１６は、１．５以上に設計さ
れている。Reference numeral 16 designates a connecting pipe which is bent in an oval shape and whose lower end opens into a spouting body 18 which will be described later, and whose upper part is fixed to the main body upper tray 17 and whose upper part widens in a trumpet shape. Part 15
The communication pipe 16 is designed to have a larger diameter than the outer diameter of the pipe, and in order to eliminate overflow of liquid at the connecting part, the ratio of the inner diameters of the two is set to be 1.5 or more, assuming that the spout pipe 14 is 1. There is.

そしてこの連絡管１６の上部には注出管端部１５が挿入
され、注出管端部１５の外周と連絡管１６内周の間には
空気流通用の隙間αが形成されており、連絡管１６の下
端は注出体１８内に開口している。The spouting pipe end 15 is inserted into the upper part of the communicating pipe 16, and a gap α for air circulation is formed between the outer periphery of the spouting pipe end 15 and the inner periphery of the communicating pipe 16. The lower end of tube 16 opens into spout body 18 .

前記注出体１８は、本体２に形成した窓孔１９に沿って
上下方向に適度な摩擦力をもって摺動固定し得るように
取付けたものであり、その下部にはコツプ等の容器２１
に注水するための注出口２０を有している。The pouring body 18 is attached so that it can be slid and fixed in the vertical direction along a window hole 19 formed in the main body 2 with an appropriate frictional force, and a container 21 such as a pot is placed at the bottom of the spouting body 18.
It has a spout 20 for pouring water into it.

り高められ蒸気圧が高くなっても自然吐出が生じること
かない。When pouring hot water using the air pot configured as described above, by moving the spout body 18 up and down according to the height of the container 21, the distance between the spout 20 and the container 21 can be kept constant, and hot water can be poured. Although it is possible to pour hot water without causing it to scatter outside, in the air pot of the present invention, the opening position of the spout pipe end 15 that hangs downward from the top of the spout pipe 14 is kept warm when the plug is closed. By setting the height at approximately the same height as the upper end of the bottle 3, spontaneous discharge will not occur even if the air inside the heat-insulating bottle 3 is increased by the liquid and the vapor pressure becomes high.

またエアーポンプが押圧作動し、保温瓶３内に空気を送
り込んで液体を注出する場合も、注出管端部１５の外周

体流出をとめることができる。Also, when the air pump operates under pressure to send air into the thermos bottle 3 and dispense liquid, air enters from the outside between the outer periphery of the dispensing pipe end 15 and the inner periphery of the connecting pipe 16. Since a sufficient gap α is formed, the siphon phenomenon does not occur, and the liquid outflow can be immediately stopped when the pressure of the pump is released.

更にエアーポンプの作用による注出管１４内の強制注出
から、前記接続部の隙間αから空気が流れ込み自然流下
に移る連絡管１６の径を大きく設計したので、接続部で
のオーバーフローが生じることもない。Furthermore, the diameter of the connecting pipe 16 is designed to be large so that air flows from the gap α in the connecting part and flows naturally from the forced pouring in the spouting pipe 14 by the action of the air pump, so overflow at the connecting part does not occur. Nor.

方向からでも確認し易く、注ぎ過ぎて液体が容器からこ
ぼれたりすることが少なくなる。Moreover, since the spout pipe end opening at the top of the spout pipe is loosely fitted into the connecting pipe inside the main body, only the spout body protrudes from the front of the main body, and there is no flow into the container. It is easy to check the amount of liquid dispensed from any direction, and it is less likely that the liquid will spill out of the container due to over-pouring.
