JP 2006-290406 A.

  In the above-described beverage dispensing cock, the operation lever is supported by the holding portion so that the ball portion can rotate, and the operation portion can be rotated back and forth. When returning from the foam pouring position to the closing position, it did not stop at the closing position. Therefore, after tilting the operating part of the operating lever from the closed position to the liquid pouring position or the foam pouring position and pouring beverage from the liquid or foam pouring nozzle, the operating part of the operating lever is moved to the liquid pouring position. Alternatively, when trying to return from the foam dispensing position to the closed position, the position of the operation lever operation section is set substantially vertically to a position where the liquid or foam dispensing nozzle is not poured out. Therefore, it is necessary to confirm that it is in the closed position, and it is troublesome to return the operation part of the operation lever while adjusting it to the closed position. In addition, since the operation portion of the operation lever is not stopped at the closed position, if a hand or the like collides unintentionally with the operation portion of the operation lever, a beverage may come out. The present invention aims to solve such problems.

  In order to solve the above-mentioned problems, the present invention provides a cock body having a pouring nozzle having a pouring hole communicating with the inner hole through which the beverage flows from one end side thereof, and a coaxial in the inner hole. A valve mechanism part for inflowing and shutting off the beverage from the inner hole to the dispensing hole by being opened or closed by being accommodated in the valve, and a valve mechanism which is coaxially accommodated in the inner hole and moves in the inner hole The slider that opens or closes the part and the operation part that extends from the ball part with the ball part rotatably supported by the holding part formed in the cock body tilts between the pouring position and the closing position. In the beverage dispensing cock provided with an operation lever that operates to open or close the valve mechanism by moving the valve mechanism, the locking portion is in the ball portion and the operation portion is in the closed position in the holding portion It is characterized by having a locking part of the ball part and a locked part that can be locked. It is intended to provide a beverage dispensing cock.

  In the beverage pouring cock configured as described above, the locking portion can be locked to the ball portion and the holding portion can be locked to the locking portion of the ball portion when the operation portion is in the closed position. Because when the operating part of the operating lever is returned from the pouring position to the closed position, the locking part of the ball part is locked to the locked part of the holding part and stops. The operation lever can be reliably stopped at the closed position without confirming the position where the beverage is not dispensed from the nozzle. This facilitates the operation when the operating lever is set to the closed position. Also, even if the operation lever is in the closed position and the hand hits the control part unintentionally, the locking part of the ball part is locked to the locked part of the holding part, so it is poured out. The beverage is not poured out from the nozzle for use.

When the slider 31 moves to the rear side, the large-diameter portion (foam dispensing valve element) 42a of the valve stem portion 42 is attached to the ring-shaped seal member 32 provided on the rear end surface of the slider (foam dispensing valve seat) 31. Sit down. As a result, the beer sent from the beverage supply conduit 11 is not poured out from a foam dispensing nozzle into a container such as a mug (not shown). At this time, when the arm 53 is tilted from the front side to the substantially vertical position, the large spherical portion 51 moves to the upper side from the lower surface of the step portion of the through hole 24a while rotating, and the large spherical portion 51 of the operation lever 50 The front side portion of the annular protrusion 51a moves into the annular groove 24b and the rear side portion of the annular protrusion 51a is lightly engaged with the upper corner of the rear side portion of the annular groove 24b and stops. Thereby, when returning the operation lever 50 from a bubble extraction position to a closed position, it can be reliably stopped at a closed position.

  As described above, the beverage dispensing cock 20 according to the present invention is large when the large sphere 51 of the operation lever 50 is in the annular protrusion 51a and the holding portion 24 is in the closed position of the operation 52 of the operation lever 50. An annular protrusion 51a of the sphere 51 and an annular groove 24b that can be locked are provided. When the operation portion 52 of the operation lever 50 is returned from the liquid pouring position or the bubble pouring position to the closed position, the annular protrusion 51a of the large spherical portion 51 is locked to the upper corner of the annular groove 24b of the holding portion 24. Therefore, the operation lever 50 can be reliably stopped at the closed position. Thereby, when the operation lever 50 is set to the closed position, the operation lever 50 can be returned to the closed position without confirming the position where the liquid or foamed beer is not discharged from the respective discharge nozzles 22 and 23. . Further, even if the operation part 52 of the operation lever 50 is unintentionally hit by a hand or the like, the annular protrusion 51a of the large sphere part 51 is lightly engaged with the upper corner of the annular groove 24b of the holding part 24 and stopped. Therefore, the beverage is not poured out from each of the dispensing nozzles 22 and 23.

  Further, the operation portion 52 of the operation lever 50 is integrally connected to the large sphere portion 51 in which the annular protrusion 51a is formed. When the operation portion 52 of the operation lever 50 is operated to return from the liquid pouring position or the bubble pouring position to the closed position, the operation portion 52 has a rear side portion or a front side portion of the annular groove 24b. Since the feeling when entering the groove beyond the upper corner is transmitted, it can be seen that the touch of the hand having the operation portion 52 has returned from the liquid dispensing position or the bubble dispensing position to the closed position.

  In the beverage pouring cock of the present embodiment, the locked portion formed on the inner peripheral surface of the holding portion 24 is the annular groove 24b, but the present invention is not limited to this, as shown in FIG. Further, the annular protrusion 24Ab may be formed on the inner peripheral surface of the holding portion 24, and when this is done, the same effects as described above can be obtained.

  The beverage dispensing cock of the present embodiment moves the large spherical portion 51 up and down when tilting the operation portion 52 between the closed position and each dispensing position. If the respective diameters of the annular protrusion 51a and the annular groove 24b are adjusted so that the 51a is slightly locked to the upper corner of the annular groove 24b of the holding part 24, the operation part 52 can be moved between the closed position and the pouring position. It is not necessary to move the large sphere part 51 up and down when tilting between them.
