DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a plug for a liquid container according to the present invention will be described in detail with reference to several examples. (Embodiment 1) FIG. 1 is a sectional view of a plug for explaining a first embodiment of the present invention, showing a closed state. The plug according to the first embodiment relates to the improvement of the conventional plug illustrated and described with reference to FIGS. 7 and 8. In the drawing, the same components as those illustrated in FIGS. 7 and FIG.
The same reference numerals are given and the detailed description is omitted. The plug 1 according to the first embodiment illustrated in FIG. 1 includes a conventional one-touch plug 51 illustrated and described in FIGS. 7 and 8, a plug body 5, a valve rod 8, a valve 9, a push button 12, a flap 13, and the like. Has a common structure and arrangement. However, the plug 1 of the first embodiment has a spring coil spring S supported on the lower surface of the push button 12 and on the flat surface 3c of the space 5b in the upper portion of the plug main body 5 whose lower end is connected to the guide cylinder 3a of the inner cylinder 3.
And push button 12 is urged upward. Thus, the end portion 13a of the flap 13 that is rotatably supported on the shaft 15 and connected to the push button 12 is urged upward.

Thus, when pouring out the hot and cold water contained in the liquid container 50, in FIG. 1, when the push button 12 is pressed downward, the urging force of the spring coil spring S is overcome and the push button 12 is pressed. The operating rod body 12a connected continuously slides downward in the guide cylinder 3a of the inner cylinder part 3, and its lower end contacts the upper end of the valve rod 8 to push the valve rod 8 downward. As a result, the valve element 9 connected to the valve rod 8 moves downward and separates from the lower inlet 7, and the liquid passage 4 in the plug body 5 passes through the lower inlet 7 of the liquid container 50. Communicate with the inside.

At the same time, when the push button 12 is pressed downward, the flap end 13a rotatably connected to the push button 12 rotates about the shaft 15 and pushes down, and as a result, the flap 13 The covering portion 13b, which has covered the upper outlet 6 of the above, abuts at the opening edge and rises above the opening of the upper outlet 6 with the portion as a fulcrum, leaves the upper outlet 6 and leaves the upper outlet 6. Is open. The push button 12 is connected to the projection 13 on the side of the flap 13.
By locking d to the locking claw 14c below the guide groove 14b (see FIG. 8), the repulsive force of the spring coil 11 that is urging the valve rod 8 is received, and the vertical movement is stopped. In this state, the inside of the container 50 communicates with the outside through the lower inlet 7, the liquid passage 4, and the upper outlet 6, so that the liquid such as hot water stored in the container 51 can be poured out.

When the upper and lower outlets 6 and 7 are closed after the hot and cold water is poured out, the cover 13 of the upper outlet 6 of the flap 13 opened upward in FIG.
b (see FIG. 7), the end 13 of the flap 13 supported on the push button 12 by the shaft 15
a is actuated upward, and pushes the push button 12 connected thereto upward so as to disengage it from the engaged locking member. At the same time, the spring coil spring S pushes the push button 12 upward. The valve stem 8, which has been stopped moving along with the

At the same time, the push button 12 is urged upward by an urging member such as a spring coil spring S and is pushed up, and the end 13a of the flap 13 supported and connected to the push button 12 by the shaft 15 is also pushed up. . As a result, the upper outlet coating portion 13b of the flap 13 is pushed downward, and the upper outlet 6
And the outlet 6 is closed in a watertight manner.

If the packing is arranged on the contact surface of the upper outlet 6 and the outlet covering portion 13b of the flap 13 covering the outlet 6, the outlet 6 can be closed with better watertightness. Also, place the packing on one side where it abuts,
A further watertight closure is ensured by arranging a rib projecting in a position corresponding to the position of the packing on the other side in contact with the packing. In addition, the first embodiment
Has shown an example in which the spring coil spring S is used as the urging member, but the spring coil spring S is used as the urging member.
Instead of using a leaf spring, a member having elasticity such as rubber or synthetic resin can be used, and the same operation and effect can be obtained.

As described above, the plug 1 according to the first embodiment of the present invention has the upper and lower outlets 6 and 7 which communicate with the liquid passage 4 formed in the stopper body 5 when the push button 12 is pressed. Is opened, and the upper and lower outlets 6 and 7 are closed by pushing down a flap 13 covering the upper outlet 6 connected to the push button 12, thereby simplifying the structure. The assembly cost is low and the operation is easy. In addition, the flap 13 which is open upward in the open state is inevitably pushed down from above by carrying a lid cap on the part when carrying, so that the upper and lower outlets 6 and Since the entrance 7 is closed,
Even if the user forgets to close the valve body, the closing can be surely guaranteed. Further, since an urging member is provided so that the flap 13 for closing the upper outlet 6 is forcibly brought into close contact with the upper outlet 6, hot water remaining when the plug is closed in the plug body is externally provided. It does not scatter and is more suitable for carrying. In addition, since the urging member such as the spring coil spring S is disposed by effectively utilizing the space below the conventionally arranged push button 12, the conventional plug can be easily installed without any design change. .

(Embodiment 2) Next, as Embodiment 2, another example in which the arrangement position of the urging member is directly arranged on the flap will be described with reference to FIG. In addition, the plug 2 of the second embodiment
1 is different from the plug 1 of the first embodiment shown in FIG. 1 only in the arrangement position of the spring coil spring S which is an urging member, and the other components are the same as those of the plug 1 of the first embodiment shown in FIG. Therefore, these common components are denoted by the same reference numerals as those in FIG. 1 and detailed description is omitted. That is, in the plug 21 of the second embodiment, as shown in FIG. 2, one end has a covering portion 13b for covering the outlet 6 on the upper part of the plug body 5, and the other end 13a is provided on the push button. The connecting end 13a of the flap 13 rotatably supported and connected by the shaft 15 is supported on the lower surface of the end 13a and the upper surface of the operating rod 12a connected to the push button 12 at the lower end. A spring coil spring S is arranged and urged upward to push up.

The opening and closing operation of the plug 21 is performed by depressing the push button 12 as in the first embodiment, whereby the valve 9 is separated from the lower inlet 7 and communicates with the liquid passage 4 in the plug main body 5. At the same time, the end 13a of the flap 13 descends as the push button 12 descends,
The covering portion 13b that covers the upper outlet 6 is opened upward with the edge of the upper outlet 6 as a fulcrum, the upper outlet 6 is opened, and the liquid passage 4 communicates with the outside. As a result, the liquid passage 4 of the stopper main body 5 allows the liquid to flow through the lower inlet 7 and the upper outlet 6.

The closing operation of the plug 21 is also performed by pushing down the covering portion 13b of the open flap 13 in the same manner as in the first embodiment, by using the edge of the upper outlet 6 as a fulcrum. The edge 13a rises upward, and the push button 12 which is pivotally supported and connected so as to rotate is pushed upward, and the engagement locking the valve rod 8 at the bottom dead center is released, The valve rod 8 is urged upward by the spring coil 11, whereby the valve element 9 contacts the lower inlet 7 and closes the inlet 7. At the same time, the upper outlet 6 is covered with the covering portion 13b of the flap 13, and the upper end of the upper outlet 6 is urged upward by the spring coil spring S disposed at the end 13a of the flap 13. The covering portion 13b of the flap 13 is forcibly pressed against the upper outlet 6 with the fulcrum as a fulcrum, and the outlet 6 is tightly closed. As a result, the cover 13b is tightly closed and remains in the liquid passage 4 after the closing. The liquid does not scatter outside the inside of the stopper body 5.

The packing P is arranged on the contact surface of the upper outlet 6 and the outlet covering portion 13b of the flap 13 covering the outlet 6, and the packing is arranged on the other side in contact with the packing. It is the same as in the first embodiment that a more watertight closure is ensured by arranging the protruding ribs at positions corresponding to the positions. In the first embodiment, the example in which the spring coil spring S is used as the urging member is shown.
