FIG. 3 is a longitudinal sectional view of the cock in an exploded state.
The beverage pouring cock includes a cock main body 2 that is detachably attached to a pouring pipe 19 provided protruding from the beverage container 1 via a mounting screw 20, and a valve that opens and closes the spout 3 formed in the cock main body 2. A function unit 4 and an operation lever 5 for opening and closing the valve function unit 4 are provided.

  As shown in FIG. 2, the cock body 2 includes a joint 22 that is continuous with the pouring pipe 19 of the beverage container 1, and a pipe-shaped spout 3 that extends continuously downward from the joint 22. 21 is formed in an L shape. The upper part of the spout 3 is cylindrical and protrudes upward, and is formed in a mortar-shaped tapered surface 33 whose upper end surface becomes lower toward the center side. Above the spout 3, there is an accommodating part 23 for the valve function part 4. As shown in FIG. 3, the accommodating part 23 of the valve function part 4 is formed so that the upper surface side is opened, and a cap 7 is detachably attached to the upward opening part 6 via a male screw 24a and a female screw 24b. ing. The cap 7 is provided with a cylindrical guide part 25 through which the valve function part 4 is inserted.

The valve function part 4 is formed by two members, a round rod-shaped valve body 26 formed of a hard resin and a plug body 27 formed of silicon rubber in a bottomed cylindrical shape. As shown in FIG. The valve tip portion 28 formed at the lower end portion of 26 is fitted into the valve tip receiving portion 29 formed at the bottom portion of the plug body 27 to couple them together. As shown in FIG. 3, the plug body 27 is formed with a flat portion on the outer peripheral portion of the lower surface that closes the inlet side of the spout 3, and the outer diameter of the plug 8 is the inlet of the spout 3. It is slightly larger than the diameter of the cylindrical portion on the side. A flange 9 is provided on the upper part of the valve body 26, and the flange 9 is inserted through the guide 25 of the cap 7 and protrudes from the cap 7. A flange portion 30 is provided at an intermediate portion of the valve body 26, and the coil spring 31 is disposed in a compressed state between the flange portion 30 and the upper wall of the cap 7.
The valve function part 4 is always urged downward by the coil spring 31, and the closing part 8 of the plug 27 is pressed against the upper end surface of the spout 3 by the force of the coil spring 31 to close the spout 3. At this time, since the upper end surface of the spout 3 is a mortar-shaped tapered surface 33, as shown in FIG. 2, the closing portion 8 of the plug body 27 is deformed and is in close contact with the tapered surface 33. Since the portion 8 is crushed and expanded so as to surround the outer periphery of the tapered surface 33, the inlet of the spout 3 is surely blocked by the plug 27, and the beverage is spouted even if the shaft of the valve 26 is slightly inclined. No leakage from 3 A ring-shaped flange edge portion 32 is provided on the upper edge of the plug body 27 toward the outer peripheral side, and the flange edge portion 32 is sandwiched between the upper edge of the cock body 2 and the cap 7.

As shown in FIG. 1, the operation lever 5 has an operation unit 10 in the upper part and a connection part 11 to the valve function part 4 in the lower part. The connecting portion 11 includes two opposing side walls 12 and 12 and a horizontal shaft 13 extending between the side walls, and inserts the hook-like portion 9 of the valve function unit 4 between the side walls 12 and 12. The valve function unit 4 and the operation lever 5 are connected by being hooked on the horizontal shaft 13.
The side wall 12 comes into contact with the upper surface of the cap 7 when the operation lever 5 is tilted to the rear side with the horizontal shaft 13 as a fulcrum, and the horizontal front end surface 14 that comes into contact with the upper surface of the cap 7 when the operation lever 5 stands up. And a restraining contact portion 16 that restrains the lever to fall, and allows the operation lever 5 to come into contact with the upper surface of the cap 7 when the operation lever 5 is tilted forward and to return to the standing state by the urging force of the valve function portion 4. The non-restraining contact portion 17 is provided. The non-restraining contact portion 17 is an arcuate surface provided at the corner between the front edge 15 of the side wall 12 and the tip surface 14, and the non-restraining contact portion 17 is the front edge 15 of the side wall 12. It protrudes slightly to the front side and is continuously formed up to a position higher than the horizontal shaft 13. The restraining contact portion 16 is provided at the rear edge of the side wall 12, and is continuous at a right angle via the tip surface 14 and the corner portion 18. As shown in FIG. 4, the distance X1 between the restraining contact portion 16 and the horizontal shaft 13 and the distance X2 between the non-restraining contact portion 17 and the horizontal shaft 13 are larger than the distance Y between the tip surface 14 and the horizontal shaft 13. It is long.
The corner 18 between the front end surface 14 of the side wall 12 and the restraining contact portion 16 may be chamfered with a small R, so that when the operation lever 5 is tilted rearward, the catch at the corner 18 is small. In this case, the size of R needs to be smaller than the distance Y between the front end surface 14 of the side wall 12 and the horizontal shaft 13 in order to restrain the operation lever 5 in the lying state. . Further, the angle between the front end surface 14 of the side wall 12 and the restraining contact portion 16 may be formed at an angle slightly larger or smaller than 90 °.

  As shown in FIG. 2, the operation lever 5 is pulled downward by the urging force of the coil spring 31, the tip end surface 14 of the side wall 12 abuts on the upper surface of the cap 7, and stands on the cap 7. In this state, the spout 3 is closed by the closing portion 8 of the plug body 27 of the valve function portion 4.

As shown in FIG. 5, when the operation lever 5 is tilted 90 ° toward the rear side, the distance X1 between the restraining contact portion 16 and the horizontal shaft 13 is made longer than the distance Y between the tip surface 14 and the horizontal shaft 13. Therefore, the valve function portion 4 is pulled upward against the urging force of the coil spring 31 to open the spout 3, and the restraining contact portion 16 formed at right angles to the tip surface 14 is formed on the upper surface of the cap 7. By abutting, the operation lever 5 is restrained in a lying state, and the beverage can be poured continuously into the cup C with the hand released from the operation lever 5.
On the other hand, as shown in FIG. 6, when the operation lever 5 is tilted forward while pressing the operation unit 10 by hand, the non-restraining contact portion 17 contacts the upper surface of the cap 7, and the non-restraining contact portion 17 and the horizontal shaft 13 are moved. Since the distance X2 is longer than the distance Y between the tip surface 14 and the horizontal shaft 13, the valve function unit 4 is similarly lifted upward against the urging force of the coil spring 31, and the spout 3 Opens and the beverage is poured into the cup C. At this time, as the angle at which the operation lever 5 is tilted is increased, the amount by which the valve function unit 4 is pulled up increases, so that the beverage can be poured out while adjusting the flow rate. When the hand is released from the operation lever 5, the unconstrained contact portion 17 formed on the arcuate surface is in contact with the upper surface of the cap 7, so that the operation lever 5 rises and returns by the force of the coil spring 31 and pours out the beverage. Stops.

  Since the operation lever 5 and the valve function unit 4 rotate freely around the vertical axis (the central axis of the valve body 26), the direction in which the operation lever 5 is tilted is a direction that can be easily operated according to the shape of the beverage container 1 and the like. It can be changed freely. For example, the beverage can be poured out by tilting the operation lever 5 in the left-right direction or the diagonally front-back direction.

  The beverage pouring cock is configured so that the cap 7, the valve function unit 4 and the operation lever 5 are integrated with each other by turning the cap 7 and removing the screws 24a and 24b and then pulling it straight upward. As shown in FIG. 7, the lever 9 of the valve function unit 4 is pulled out of the horizontal shaft 13 of the operation lever 5 while the valve function unit 4 is pushed upward, so that the operation lever 5 can be easily removed. Can be removed. Thereafter, the valve function unit 4 is pulled out below the cap 7, the plug 27 is pulled down and separated from the valve body 26, so that each component can be disassembled very easily as shown in FIG. 3. . The cock body 2 can also be removed from the beverage container 1. Assembly may be performed in the reverse order of disassembly. By disassembling and cleaning in this way after daily use, it can always be used in a hygienic state.
