[0009]

[Action]

 In the liquid container of the present invention, each time the operation button provided on the handle upper position is pressed once, the valve element is sequentially displaced between the valve closing position and the valve opening position via the valve element operating member. In addition, the valve body position holding mechanism holds the valve body in the closed position and the open position. Therefore, even if you release your finger from the operation button in the valve-opened state, the valve body remains in the valve-opened position, and the liquid injection operation can be performed without touching the operation button with your finger. Further, since the valve body, the valve body operating member and the valve body position holding mechanism are provided in the stopper body, these members can be unitized together with the stopper body. Furthermore, since the operating end of the operation button returns to the outside of the plug by the urging force of the spring in the non-operation state, the operation button may interfere with the opening / closing operation of the plug regardless of the open / closed state of the valve. Absent.

To do.

Next, the valve body position holding mechanism 5 of the individual embodiment will be described. First, the valve body position holding mechanism 5 of the first embodiment shown in FIGS. 1 and 2 employs what is called a push-push mechanism. That is, the valve body position holding mechanism 5 of the first embodiment is provided at a position closer to the front part of the valve body operating member 4, and the rotating body 51 provided on the valve body operating member 4 side is connected to the plug body. It is slidably inserted into a horizontally-oriented cylindrical guide tube 52 which is fixed inside 2. A push-push mechanism of this type has been conventionally used as shown in, for example, Japanese Utility Model Laid-Open No. 58-98033 or Japanese Utility Model Laid-Open No. 2-116239. Each time the body operating member 4) is pressed once, the rotator 51 rotates by a predetermined small angle, and the rotator 51 moves toward the guide cylinder 52 sequentially toward the front position (FIG. 1) and the rear position (FIG. 1). 2) and the valve element operating member 4 are retained in the retracted position and the advanced position, respectively. As shown in FIG. 1, when the valve body operating member 4 is in the retracted position, the valve body 3 is held in the closed position, and conversely, as shown in FIG. The valve body 3 is held in the open position when the valve is in the position.

The valve body position holding mechanism 5 of the second embodiment shown in FIG. 3 is provided at a position near the rear part of the valve body operating member 4. The valve body position holding mechanism 5 of the second embodiment basically has the same structure as the valve body position holding mechanism 5 of the first embodiment, and the formation position thereof is the front portion of the valve body operating member 4. Only the difference between the leaning position and the rearward position.

The valve body position holding mechanism 5 of the third embodiment shown in FIG. 4 is provided in the valve body valve rod 32 portion. That is, in the valve body position holding mechanism 5 of the third embodiment, the rotating body 51 is attached to the valve body valve rod 32, and the rotating body 51 moves up and down in the vertically oriented guide cylinder 52 together with the valve body 3. To be able to slide into.

In the fourth embodiment shown in FIG. 5, the valve body position holding mechanism 5 has the same structure as that of the third embodiment (FIG. 4), but the operating force of the valve body operating member 4 is used to hold the valve body position. A lever member 46 is used to transmit to the mechanism 5. That is, in the fourth embodiment, when the valve element operating member 4 is slid, the lever member 46 is operated by the cam 41 provided on the upper surface of the valve element operating member 4 to operate the valve element position holding mechanism. The rotating body 51 of No. 5 is pushed down.

The valve body position holding mechanism 5 of the fifth embodiment shown in FIGS. 6 and 7 includes a needle-shaped body 54 projecting downward from the lower surface of the upper plate 25 of the plug body 2 and a valve body operating member 4. It is composed of a substantially heart-shaped annular groove 55 formed on the upper surface. The lower end of the needle-shaped body 54 is fitted in the annular groove 55, and the needle-shaped body 54 follows the annular groove 55 as the valve body operating member 4 is slid to move the annular groove 55 in the front-rear direction. Then, it swings only in the left-right direction (direction of arrow A or B in the state shown in FIG. 7). When the valve body operating member 4 is at the retracted position (arrow D side), the needle-shaped body 54 is locked by the front side locking portion 55a of the annular groove 55 to move the valve body operating member 4 to the retracted position (valve). When the valve body operating member 4 is slid in the direction of arrow C from the retracted position to the advanced position while the position is maintained at the valve closed position of the body 3, the needle-shaped body 54 is displaced as shown by arrow P (substantially the annular groove). 55 is moved), the needle-shaped body 54 is locked by the rear side locking portion 55b of the annular groove 55 as shown by reference numeral 54 ', and the valve body operating member 4 is moved to the forward position (the valve body 3 is opened). Position). Further, when the valve body operating member 4 in the forward movement position is pushed forward again, the needle-shaped body 54 which has been locked by the rear locking portion 55b of the annular groove 55 is unlocked, and subsequently the valve 43 is driven by the spring 43. The body operating member 4 is moved rearward (arrow D side) (at that time, the needle-shaped body 54 moves in the annular groove 55 as indicated by arrow Q), and the needle-shaped body 54 is engaged with the front side of the annular groove 55. When locked by the stopper 55a, the valve body operating member 4 is held in the retracted position (the valve closing position of the valve body 3).

The method of use and the operation of the liquid container of each embodiment shown in FIGS. 1 to 7 will be described. First, when the operation button 8 is not operated, the operation button 8 (pressing portion 82) is retracted by the spring 80, and the plug body 2 can be screw-rotated regardless of the open / close state of the valve body 3. It is like this. When the valve body 3 is closed (the valve body operating member 4 is in the retracted position), the handle 7 is grasped with the hand, and the thumb pushes the push button portion 81 of the operation button 8 once. The valve body operating member 4 is slid forward by the pressing portion 82. Then, the cam 41 of the valve body operating member 4 operates the valve body 3 to move downward, and the valve body position holding mechanism 5 holds the valve body 3 in the open position. Incidentally, in the state where the push button portion 81 is still pushed in, for example, as shown in FIG. 2, the tip end portion of the pressing portion 82 penetrates into the hole 24 of the side wall 23 of the plug body. Then, when the finger is released from the push button portion 81, the operation button 8 is urged outward by the spring 80, so that the operation button 8 retreats from the position shown by the solid line in FIG. 2 as shown by the chain line 8 '. As a result, the pressing portion 82 is also retracted rearward to a position where it does not interfere with the plug body 2. In this state, if the handle 7 is grasped and the liquid container is tilted forward, the liquid in the inner container 12 will be discharged from the injection port 17 through the injection passage 22 and the liquid guide portion 16 in the stopper. become.

Further, in the liquid container of each of the embodiments, the valve body 3, the valve body operating member 4, and the valve body position holding mechanism 5 are respectively provided in the plug body 2 and are unitized. This makes it easier to work at times or during after-sales service.
