It pivots around the tip of the shaft. By this rotation, the pressed portion 45 at the upper end of the tubular portion 42 of the valve member 41 is pressed down, the valve member 41 is lowered, and the flow port 22 at the lower end of the main body member 21 is opened.

  At this time, the pressing portion 75 of the dispensing opening / closing operation member 71 presses the rear side from the center of the pressed portion 45 having the highest height, so that the valve member 41 has the cylindrical portion 42 and the inner cylinder of the main body member 21. It descends with a slight inclination according to the clearance with the portion 24. For this reason, the entire circumference of the circulation port 22 is not opened at a time, but a part thereof is opened first and opened stepwise.

  When the liquid container 11 is tilted with the circulation port 22 opened, the liquid in the liquid container main body 12 exits from the spout 26 through the opened circulation port 22.

  At the time of this pouring, air is introduced through the flow opening 47a on the side opposite to the pouring port 26, so that the pouring is performed smoothly.

  When the dispensing opening / closing operation member 71 is pushed down, the injection opening / closing operation member 61 loses its support and falls due to its own weight.

  As described above, the liquid can be injected as a result of the valve member 41 opening the flow port 22 when the injection opening / closing operation member 61 is pushed down. At this time, since the liquid is allowed to flow in through the circulation port portion 47a provided on the upper surface side of the closing plate 43 without providing a hole for allowing the liquid to pass through the closing plate 43 of the valve member 41, the structure is simplified. Therefore, it is possible to reduce the number of parts and to save the time and effort of assembly.

  In addition, there is no compression coil spring 51 for urging the valve member 41 in the tubular portion 42 of the valve member 41, which is a passage for injection, and the spring is exposed to other parts through which the liquid passes. So it is easy to keep clean.

  Further, when the plug body 15 is disassembled, as shown in FIG. 7, a member including the main body member 21, the valve member 41, the compression coil spring 51, the spring pressing member 44, the dispensing opening / closing operation member 71, and the lid member 31. It is divided into three members, the injection opening / closing operation member 61, and is easy to assemble and disassemble, and as described above, a fine member such as a spring can be omitted at the portion where the liquid touches. Easy to care for.

  Further, the spring that holds the valve closed state is constituted by one compression coil spring provided outside the cylindrical portion 42 of the valve member 41, and the injection opening / closing operation member 61 and the dispensing opening / closing operation member 71 are provided. Since this function is also used, further effects of simplification of the structure and reduction of the number of parts can be obtained.

  When the liquid is poured out, the flow opening 47a at the lower end of the communication passage 47 serves as an air inlet that smoothly dispenses the liquid, so that the operability is also good.

  In addition, the pressed portion 45 provided at the upper end of the tubular portion 42 of the valve member 41 protrudes upward in a substantially arc shape, and the dispensing opening / closing operation member 71 is provided at the operation lever portion at the rear end. When 74 is pushed down, the rear side of the pressed part 45 is pushed down (see FIG. 6), so that the valve member 41 is slightly inclined, and only a part of the flow port 22 at the lower end of the body member 21 is the other part. Even if the internal pressure in the liquid container body 12 is increased, the valve can be opened without any unexpected ejection.

In correspondence between the configuration of the present invention and the configuration of the one aspect,
The lower end of the communication path of the present invention corresponds to the flow port 47a,
Similarly,
The biasing member corresponds to the compression coil spring 51,
The present invention is not limited to the above-described configuration, and other configurations can be adopted.

  For example, instead of the compression coil spring, the urging member may be constituted by a torsion spring that is attached to the tip of the dispensing opening / closing member, and the valve member may be interlocked with the dispensing opening / closing member. .
