2 and is interlocked so as to be interlocked. That is, when the operating member 22 is operated to open the valve (sliding in the direction of arrow A), the slider 34 moves backward (moves to the right in FIG. 1), and the flap 25 is opened by the biasing force of the spring 33. Ru.
次に図示実施例の液体容器(魔法瓶)の作用を
説明する。 Next, the operation of the liquid container (thermos flask) of the illustrated embodiment will be explained.
先ず、第1図図示の状態では、弁体18は開弁
状態にあり且つフラツプ25も閉塞状態にあつ
て、魔法瓶は注出不能となつている。 First, in the state shown in FIG. 1, the valve body 18 is in an open state and the flap 25 is also in a closed state, making it impossible to dispense from the thermos bottle.
そこで、操作部材22の操作部22aを矢印A
方向に移動せしめると、カム部27とカム部41

ある。 Therefore, the operating portion 22a of the operating member 22 is
When moved in the direction, the cam portion 27 and the cam portion 41
2, the valve body 18 is pushed down and the inlet side opening 17a of the liquid passage 17 is opened as shown in FIG. At the same time, the linking portion 22 of the operating member 22
b moves back against the spring 28, and the slider 3
4 becomes free, and the flap 25 is opened by the biasing force of the spring 33 as shown in FIG. Therefore, the thermos becomes ready for dispensing.
上記の如き操作部材22の水平駆動時において

以上の力が必要となる。従つて、弁体18の不用
意な開弁が防止されることとなり、安全性が大幅
に向上する。 When the operating member 22 is driven horizontally as described above, the biasing force of the return spring 28 continues to act in a direction that opposes the horizontal drive, and when the cam parts 27 and 41 constituting the cam mechanism engage with the concave and convex portions, the valve is closed. The open state of the valve body 18 is to be maintained, and a certain amount of force is required to open the valve body 18. Therefore, inadvertent opening of the valve body 18 is prevented, and safety is greatly improved.
上記の場合において、操作部材22はリターン

カム面41a,27aが相互に凹凸係合している
ので、操作部材22はリターンスプリング28に
抗してそのまま位置保持され、弁体18を開放状
態のまま保持する。 In the above case, the operating member 22 attempts to return to its original position due to the biasing force of the return spring 28, but the arcuate cam surfaces 41a and 27a of the cam portions 41 and 27 are engaged with each other. Therefore, the operating member 22 is held in position against the return spring 28, and the valve body 18 is held in the open state.
その後、操作部22aを矢印B方向に移動せし
めると、第1図図示の注出不能状態に復帰する。
この時、操作部材22は、リターンスプリング2
8の付勢力により閉弁方向作動を助長される方向
に付勢されているため、カム部27,41の凹凸
係合を解除するだけで、自動的に復帰せしめられ
るのである。 Thereafter, when the operating portion 22a is moved in the direction of arrow B, the dispensing state shown in FIG. 1 is restored.
At this time, the operating member 22
Since the valve is urged in a direction that promotes the valve-closing operation by the urging force of 8, it is automatically returned to its original position simply by releasing the engagement of the cam parts 27 and 41 with the projections and recesses.
上記の場合において、操作部材22を矢印A−
B方向に操作するとき、操作部材22側のカム部
27は全体が凸円弧状カム面41aとされたカム

ことができる。 In the above case, the operating member 22 is
When operating in direction B, the cam portion 27 on the operating member 22 side moves while abutting against the cam surface 41a of the cam portion 41, which has a convex arc-shaped cam surface 41a as a whole, so its movement is smooth. Moreover, when the top of the convex arc-shaped cam surface 41a and the concave arc-shaped cam surface 27a engage, the operating member 22 is reliably positioned, and the valve body 18 can be reliably held in the open state.

円滑に行われる。 Next, to explain the effects of the present invention, the present invention:
A liquid passage constituting a part of a pouring passage that communicates between the inside and outside of the container body is provided in a stopper that is tightly fitted into a liquid supply port formed in a shoulder member on the upper part of the container body configured to accommodate liquid therein. At the same time, the stopper includes a valve body that is driven in the vertical direction to open and close the liquid passage and is always biased in the valve closing direction by a valve spring, and a valve body that is driven in the vertical direction to open and close the liquid passage and is normally biased in the valve closing direction by a valve spring. (1) A cam operating portion is provided at the upper end of the valve body 18; Since the cam portion 41 is formed with a convex arcuate surface 41a as a whole, and the cam portion 27 on the operating member 22 side slides in contact with the cam portion 41, the operating member 22 can be moved forward and backward smoothly.

易となる。(2) A biasing force is applied to the operating member 22 in a direction that resists the horizontal drive of the operating member 22 when the valve is operated in the valve opening direction, and a biasing force is applied to the operating member 22 when the operating member 22 is operated in the valve closing direction.
Since the return spring 28 is attached to apply a biasing force in a direction that promotes the horizontal drive of the valve body 18, the operation to open the valve body 18 is performed by a force that resists the biasing force of the return spring 28. The operation for opening the valve body 18 is facilitated by the biasing force of the return spring 28, so that inadvertent opening of the valve can be reliably prevented and the valve closing operation can be extremely facilitated.

The stopper 14 includes a valve body 18 which is driven in the vertical direction to open and close the liquid passage 17 and is always biased in the valve closing direction by a valve spring 20, and a valve body 18 which is driven in the vertical direction to open and close the liquid passage 17 and which is normally biased in the valve closing direction by the valve spring 20. The liquid container is provided with an operation member 22 that is driven by a valve element 18 and has an operation member 22 that converts the horizontal displacement into an upward and downward displacement of the valve body 18 via a cam mechanism,
The cam mechanism between the valve body 18 and the operating member 22 is formed at the upper end of the valve body 18, and includes a cam portion 41 whose entire cam action portion is composed of a convex arc-shaped cam surface 41a.
and a cam portion 27 that is integrally formed on the lower surface of the operating member 22 and has a concave arc-shaped cam surface 27a on a part of the cam action portion. 41, 27, the valve body 18 opens against the biasing force of the valve spring 20, and both the arcuate cam surfaces 41a,
The valve body 18 is held open by the convex-concave engagement of the cam parts 27a, while the valve element 18 is held open by the valve spring 20 when the cam parts 41 and 27 are disengaged.
A biasing force is applied to the operating member 22 in a direction that resists the horizontal drive of the operating member 22 when the operating member 22 is operated in the valve opening direction, and a biasing force is applied to the operating member 22 in a direction that opposes the horizontal drive of the operating member 22 when operating the operating member 22 in the valve closing direction. A liquid container characterized in that a return spring 28 is attached that applies a biasing force in a direction that promotes horizontal movement of the member 22.
