この状態では、容器本体1の内部は液体流路Cを介して
外気と連通するため、容器本体1を傾ければ、注口Bか
ら内部の湯等を注ぎ出すことが可能となる。Then, as shown in FIG. 10, when the spout B is completely opened and the upper end of the valve rod 42 is snap-fitted and locked in the recess 52 of the pressing piece 49, the opening / closing operation member 13 causes the spout B to be closed. Is held in the open state, and the valve body 12 is held in the open state of the outflow port A, so that the valve body 12 is opened. Also,
As shown in FIG. 10, the projecting member 14 projects outward from the inner peripheral surface of the cup 3 a that covers the outer surface of the shoulder body 5.
In this state, the inside of the container body 1 communicates with the outside air via the liquid flow path C, so that if the container body 1 is tilted, the hot water or the like inside can be poured out from the spout B.
流出口A及び注口Bを閉じて閉栓状態とするには、開閉

回動によりカバー45の後端が突出部材14から離れる
ため、突出部材14はコイルばね54の付勢力により内
方に引き戻され、第1図に示す状態に復帰する。In order to close the outflow port A and the injection port B to be in the closed state, the pressing portion 46 of the opening / closing operation member 13 may be lightly pressed obliquely downward. That is, when the pressing portion 46 of the opening / closing operation member 13 is pressed, the valve rod 42 is slightly pushed down by the inflection portion D of the inclined portion 51 of the pressing piece 49 and the concave portion 52 and the concave portion 52.
Since the lock with is released by snap, the valve rod 4
The urging force of the coil spring 44 pushes up the slanted portion 51 of the pressing piece 49 while sliding it. As a result, the opening / closing operation member 13 rotates counterclockwise in FIG. 10 to close the inlet B, while the valve body 12 makes pressure contact with the valve packing 16 to close the outlet A. Further, since the rear end of the cover 45 is separated from the projecting member 14 by the rotation of the opening / closing operation member 13, the projecting member 14 is pulled back inward by the biasing force of the coil spring 54, and returns to the state shown in FIG. .
開閉操作部材13の押圧部46を指で押圧する替わり
に、突出部材14の先端を押圧して開閉操作部材13を
回動させるようにしても、前記同様に閉栓することがで
きる。Instead of pressing the pressing part 46 of the opening / closing operation member 13 with a finger, the opening / closing operation member 13 can be rotated by pressing the tip of the protruding member 14, and the cap can be closed in the same manner as described above.
ところで、以上のような開閉操作部材13又は突出部材
14による閉栓操作をし忘れたまま、コップ3aを被せ
たとする。このとき、突出部材14の先端が、肩体5の
外面に被せられるコップ3aの内周面より外方に突出し
ているため、このままではコップ3aを肩体5に被せる
ことができない。By the way, it is assumed that the cup 3a is put on while forgetting to perform the capping operation by the opening / closing operation member 13 or the projecting member 14 as described above. At this time, since the tip of the projecting member 14 projects outward from the inner peripheral surface of the cup 3a that covers the outer surface of the shoulder body 5, the cup body 3a cannot be covered with the cup 3a as it is.
そこで、第10図に示すように、コップ3aを斜め上方
から肩体5に被せてゆくと、コップ3aの内面が突出部
材14の先端を押圧する。これにより、突出部材14が
内方に移動して開閉操作部材13を第10図において反
時計回りに回動させる結果、前記同様に閉栓される。Therefore, as shown in FIG. 10, when the cup 3a is slid over the shoulder body 5, the inner surface of the cup 3a presses the tip of the protruding member 14. As a result, the projecting member 14 moves inward to rotate the opening / closing operation member 13 counterclockwise in FIG. 10, and as a result, it is closed as described above.
次に、コップ3aを被せることなく開栓状態にある魔法
瓶に蓋体3bを装着したとする。この場合、第11図に
示すように、蓋体3bの把手部55が正規の位置より上
方から見て反時計回り方向に僅か一ひねり分だけずれた
ところに位置する状態で、被せるようにすればよい。Next, it is assumed that the lid 3b is attached to the thermos bottle in the open state without covering the cup 3a. In this case, as shown in FIG. 11, the grip portion 55 of the lid body 3b is placed so as to be covered in a state in which it is displaced from the normal position by a slight twist in the counterclockwise direction when viewed from above. Good.

内面の突部57が突出部材14の先端を押圧するため、
前記同様に閉栓される。When the lid 3b is put on, as shown in FIG. 12, the bayonet protrusion 56 contacts the second protrusion 9b of the shoulder body 5. When the lid body 3b is pressed against the shoulder body 5 and twisted in the clockwise direction, the projection 57 on the inner surface of the lid body 3b pushes the tip of the projecting member 14 as shown in FIG.
The cap is closed as described above.
さらに蓋体3bを回転させると、第12図に示すよう

嵌まり込み確実に取り付けられる。When the lid 3b is further rotated, as shown in FIG. 12, the bayonet protrusion 56 slides on the slope of the inclined member 9d from the second protrusion 9b of the shoulder 5 and fits into the bayonet groove 9. . At the same time, the lower end of the lock member 58 of the lid 3b comes into pressure contact with the upper end surface of the body ring 6 and is pushed up against the biasing force of the coil spring 59 (see FIG. 1). Then, the bayonet protrusion 56 slides into the bayonet groove 9 and abuts on the stopper 9c, and at the same time, the lower end of the lock member 58 is fitted into the lock recess 6a of the upper end surface of the body ring 6 and is securely attached.

6aから離脱し、ロックが解除される。In order to remove the lid 3a, first, the operation button 60 (see FIG. 1) of the lid 3b may be pushed in, whereby the lock member 58 is urged by the coil spring 59 (see FIG. 1). As a result of being pushed up against it, the lower end of the lock member 58 retracts into the handle portion 55 and separates from the lock concave portion 6a of the body ring 6, and the lock is released.
そして、この操作ボタン60を押したまま蓋体3bを反
時計回りにひねると、蓋体3bは同方向に回動し、第1

るため、蓋体3bは肩体5から取り外される。When the lid body 3b is twisted counterclockwise while the operation button 60 is being pressed, the lid body 3b rotates in the same direction, and
As shown in FIG. 2, the bayonet protrusion 56 slides in the bayonet groove 9 of the shoulder body 5 and rides on the second protrusion 9b along the inclined member 9d, and is detached from the bayonet groove 9 so that the lid body 3b is removed from the shoulder body 5.

を動作させることができるという効果を有している。(Effect of the Invention) As is apparent from the above description, according to the present invention, even if the lid is attached while the opening / closing operation member is forgotten to be operated, it is provided on the inner peripheral surface of the lid. Since the protrusion automatically and smoothly presses the protruding member, and the protruding member moves the opening / closing operation member in the closing direction, the fluid passage is closed by simply mounting the lid, and the closed state is obtained. Leakage
It is safe because it does not overflow when the lid is removed. Further, the spout is opened and closed in response to the operation of the opening / closing operation member, that is, the spout is opened only when it is used, which is sanitary. Further, the valve body is opened and closed by the cam mechanism provided on the opening / closing operation member, and the projecting member for closing the opening / closing operation member is also held by the plug body by the spring force. Thus, the valve body can be operated reliably for a long period of time.
