When the valve is opened as shown in FIGS. 10 and 2, the protrusion 51 is inserted in the guide rail 47, and the elastic force of the spring 40 urges the rotary slider 37 upward. Therefore, the valve body 11 is pressed against the valve seat 14A via the valve rod 18 to close the valve. At this time, the thick portion 45B of the short engaging portion 45 is inserted into the guide rail 47, and the thick portion 44B of the long engaging portion 44 is inserted into the proposed rail 46.

The process from the valve closed state to the valve opened state shown in FIGS. 14 and 1 will be described with reference to FIGS. 11, 12, and 13. As shown in FIG. 11, when the plate portion 20A of the elastic body 20 is pressed by the finger A, the plate portion 20A is slightly crushed, and as a result, the operation button 19 is pressed. For this reason, the engagement short portion 45 along with the engagement long portion 44 descends along the guide rails 46 and 47, and the engagement short portion 45 causes the protrusion 51 to move along the guide rail 47. To the bottom of the bottom. At this time, the valve body 11 itself also descends. Then, as shown in FIG. 12, the state in which the operation button 19 is slightly returned by the sliding of the tip 45A of the short engagement portion 45 and the inclined surface 51A of the protrusion 51 is shown in FIG. Transfer to the lower end of the inclined surface 48A of the portion 48. At the same time, the protrusion 51 contacts the inclined surface 44C of the engagement long portion 44. After this, when the finger is released from the elastic body 20 of the operation button 19, the protrusion 51 of the rotary slider 37, which is urged upward by the spring 40 as shown in FIG. 13, rises as the operation button 19 returns. It rotates while rising as the lengthening portion 44 rises. At this time, the valve body 11 also rises. Then, as shown in FIG. 14, when the protrusion 51 reaches the step portion 50, the step portion 50 causes the protrusion 51 to be positioned below the valve seat 14A, and the liquid inlet 15 is opened to open the valve. At this time, the engaging long portion 44 is pushed up by the protrusion 51, so that the top portion 41 of the operation button 19 projects from the upper lid 33 with the collar portion 43 locked to the upper lid 33. Even if an impact is applied to the finger A from the operation button 19 during this valve opening operation, the impact can be buffered because the elastic body 20 is interposed between the operation button 19 and the finger A. Then, the liquid contained in the liquid container 1 can be tilted and poured into the cup 24 or the like which has been previously removed from the liquid outlet 16 through the liquid passage 10.

To close the valve again, when the operation button 19 in the state shown in FIG. 14 is pressed with the finger A, as shown in FIG. 15, the engagement long portion 44 descends, and the protrusion 51 causes the protrusion 51 to descend. It descends below the step 50 along the guide rail 46, and the abutment of the tip 45A and the inclined surface 51A causes the protrusion 51 to transfer to the engagement short receiving portion 49, and further the spring 40 causes the protrusion 51 to incline. Ascends along the surface 49A, and finally is guided into the guide rail 47 and rapidly ascends, resulting in the valve closed state shown in FIG. Then, when the operation button 19 is pressed against the spring 40, the projection 51 moves onto the engagement short receiving portion 49, and at the same time, the operation button 19 is rapidly lowered by the pressing force to apply an impact to the finger A. However, since the elastic body 20 is interposed between the top portion 19A of the operation button 19 and the finger A, the impact can be buffered and prevented from being applied to the finger A. When the operation button 19 is forgotten to be pressed and the cup 24 and the outer lid 21 are screwed onto the shoulder member 4 in the valve open state shown in FIG. 14, the protrusion 25 of the cup 24 is changed as shown in FIG. When the lid is closed, the operation button 19 is pressed via the elastic body 20 to automatically close the valve.

As described above, the operation button 19 is provided on the upper part of the plug body 9 which is detachably provided in the mouth portion 5 of the liquid container 1, and the operation button 19 is provided so as to be movable up and down. By providing the valve body 11 for opening and closing the broken liquid passage 10 and further providing the elastic body 20 on the top portion 19A of the operation button 19, the valve body 11 is operated by putting a finger on the operation button 19. At this time, since the elastic body 20 is interposed between the top portion 19A of the operation button 19 and the finger A, the elastic body 20 can absorb a shock or the like generated during the operation. Therefore, the operation button 19 can be pressed with confidence.

16 and 17 show a second embodiment and a third embodiment of the present invention. The same parts as those of the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

In the elastic body 61 of the second embodiment, a thin wall-shaped protrusion 61A protruding on the top 19A of the operation button 19 is formed with an edge 61B that abuts against the top 19A, and the center of the protrusion 61A is formed. A shaft portion 61C is vertically provided from the above, and a retaining portion 61D is formed at the lower end of the shaft portion 61C. Therefore, in this elastic body 61, since the hollow portion 61E is provided between the protrusion 61A and the top portion 19A, the cushioning action can be further enhanced.

In the elastic body 71 of the third embodiment, a protrusion 71B is provided at the center of a flat plate portion 71A placed on the top portion 19A of the operation button 19, and a shaft portion 71C is hung from the flat plate portion 71A. A retaining portion 71D is formed at the lower end of the shaft portion 71C. Therefore, in this elastic body 71, by providing the protrusion 71B at the portion of the flat plate portion 71A where the finger is put, the cushioning action can be further enhanced.

The present invention is not limited to the above-described embodiment. For example, the elastic body may not be provided separately from the operation button but may be integrally provided, and the elastic body may be adhered to the operation button. Further, the stopper may press the operation button with a finger to close the fluid passage with the valve body when the operation button is in the upper stop position, and press the operation button again with the finger to perform the operation.
