  Next, the operation of this embodiment will be described. Since a known structure is basically used except for the opening / closing means 12, description thereof is omitted.

  In the neutral position of FIG. 5, the crushing portion 35 of the long arm portion 33 of the driven portion 17 crushes the flexible tube 11. The driven portion 17 is moved by the holding mechanism 41, that is, when the first contact portion 32 of the rotation operation portion 16 and the second contact portion 38 of the driven portion 17 are in contact with each other. 35 is held in a state where the flexible tube 11 is crushed. In this state, the second pressed portion 42 is slightly separated from the pressing protrusion 29. That is, in this state, the second pressed portion 42 is not pressed by the pressing protrusion 29. And the flexible tube 11 is crushed in this way, the said extraction path | route 10 is closed, and drinks, such as beer in the said drink storage part 5, are not poured out from this extraction path | route 10. Yes.

  Then, as shown in FIG. 6, when the cock lever 14 is rotated counterclockwise and tilted slightly forward, the first contact portion 32 of the rotation operation portion 16 is moved to the second contact of the driven portion 17. Separate from the contact 38. At this time, due to the elastic restoring force of the flexible tube 11 itself, the long arm portion 33 of the driven portion 17 is rotated counterclockwise about the second rotation shaft 21 and pushed up. At the same time, the second inclined portion 28 of the pressing protrusion 29 of the rotation operation portion 16 abuts on the second pressed portion 42 of the driven portion 17, and the second pressed portion 42 and the second inclined portion 28. The second pressed portion 42 is pushed down by the pressing protrusion 29 while sliding. As a result, the short arm portion 34 rotates counterclockwise around the second rotation shaft 21 and is pushed down. In this state, the dispensing path 10 in the flexible tube 11 is in a half-open state, and beverages such as beer in the beverage storage unit 5 are poured out from the dispensing path 10.

  Then, as shown in FIG. 7, when the cock lever 14 is tilted forward to the end, the short arm portion 34 of the driven portion 17 rotates counterclockwise around the second rotation shaft 21, It is pushed down to the lower position. At the same time, the long arm portion 33 of the driven portion 17 rotates counterclockwise about the second rotation shaft 21 and is pushed up to the uppermost position. At this time, the protruding portion 36 provided on the long arm portion 33 of the driven portion 17 enters the concave portion 26 formed in the rotating operation portion 16. In addition, since the distance from the second rotating shaft 21 to the pressed portion 40 is shorter than the distance from the second rotating shaft 21 to the crushed portion 35, the distance from the ascending distance of the pressed portion 40 is increased. The rising distance of the crushing portion 35 is larger. Therefore, by optimizing the length condition of the distance from the second rotating shaft 21 of the driven portion 17 to the pressed portion 40 and the distance to the crushing portion 35, the crushing portion 35 in the state of FIG. However, the flexible tube 11 is not pushed. Thus, when the crushing part 35 does not push the flexible tube 11, that is, when the dispensing path 10 in the flexible tube 11 is in a fully open state, the inside of the beverage storage section 5 from the dispensing path 10. Beverages such as beer are poured out at the maximum flow rate.

  When stopping the dispensing of the beverage, the user only has to release his hand from the cock lever 14. As described above, when the user releases his / her hand from the cock lever 14, the rotation operation unit 16 is rotated clockwise by the biasing force of the torsion coil spring (not shown). When the rotation operation unit 16 rotates clockwise, the inclined portion 27 of the pressing portion 31 comes into contact with the pressed portion 40 of the driven portion 17, and the pressed portion 40 and the inclined portion 27 slide. The pressed part 40 is pushed down by the pressing part 31 while moving. Accordingly, the long arm portion 33 is rotated clockwise around the second rotation shaft 21 and pushed down. Thus, when the long arm portion 33 is pushed down, the crushing portion 35 provided at the distal end portion of the long arm portion 33 crushes the flexible tube 11. Then, as shown in FIG. 8, the rotation is further performed in a state where the convex curved surface portion 30 of the pressing portion 31 of the rotational operation portion 16 and the convex curved surface portion 39 of the pressed portion 40 of the driven portion 17 are in contact with each other. When the operation part 16 rotates clockwise, the convex curved surface part 30 of the rotational operation part 16 exceeds the convex curved surface part 39 of the driven part 17, and the rotational operation part 16 as shown in FIG. The first contact portion 32 and the second contact portion 38 of the driven portion 17 are in contact with each other. Thus, since the said flexible tube 11 is crushed by the said crushing part 35, the said extraction path | route 10 is closed, Therefore Drinks, such as beer in the said drink storage part 5, are poured from this extraction path | route 10. It will not be issued. When the flexible tube 11 is crushed, the holding mechanism 41, that is, the first contact portion 32 of the rotation operation portion 16 and the second contact portion 38 of the driven portion 17 are in contact with each other. It is held by touching. As described above, since the distance from the second rotation shaft 21 to the pressed portion 40 is shorter than the distance from the second rotation shaft 21 to the crushing portion 35, The descending distance of the crushing portion 35 is larger than the descending distance. Therefore, by optimizing the length condition of the distance from the second rotating shaft 21 of the driven portion 17 to the pressed portion 40 and the distance to the crushed portion 35, the crushed portion 35 is From the state where the flexible tube 11 is not pushed, the flexible tube 11 can be crushed as shown in FIG. 5 to completely close the dispensing path 10 in the flexible tube 11.

  From the state shown in FIG. 5 to the state shown in FIG. 9, the cock lever 14 can be tilted to turn the turning operation unit 16 clockwise about the first turning shaft 19. At this time, the first abutting portion 32 (third cylindrical portion 25) and the second abutting portion 38 are each arc-shaped, and their radii are substantially equal. Even if it is rotated, the first contact portion 32 only slides with the second contact portion 38, and the driven portion 17 does not rotate about the second rotation shaft 21. . When the rotation operation unit 16 is rotated clockwise, the other opening / closing means (not shown) is operated. Since the opening / closing means has the same structure as the opening / closing means 12 as described above, description thereof is omitted.
