A ring body 22 for holding the measuring instrument 2a on the cock body 1, a valve body 3 inserted in the center of the lid body 20, the cock body 1 and the measuring instrument 2a, and a coil spring 23 for biasing the valve stem 3a downward. And an operation unit 4 connected to the upper end of the valve stem 3a.

  As shown in FIG. 1, the cock main body 1 includes an empty chamber 24 that penetrates vertically, and a connecting pipe 25 that is inserted into the mouth 10 a of the bottle 10 is provided upright and provided continuously behind the empty chamber 24. It is. A packing 26 corresponding to the inner diameter of the mouth portion 10 a of the bottle 10 is attached to the connecting tube 25. A partition 27 is provided inside the connecting pipe 25 to secure a flow path for liquid and air. The upper and lower portions of the vacant chamber 24 are opened in a circular shape, and the central axis C of the vacant chamber 24 is inclined forward with respect to the vertical direction. The forward tilt angle θ is preferably 5 to 15 °, and the illustrated forward tilt angle θ is 12 °. The liquid inlet 6 to the measuring instrument 2a is provided in a constricted form at the lower part of the empty chamber 24, and a screw 28 that is screwed with the ring body 22 is formed at the outer peripheral part below the liquid inlet 6. . A packing 29 that is in close contact with the upper end surface of the measuring instrument 2 a is provided on the lower end surface of the empty chamber 24.

The measuring device 2a is formed in a substantially bowl shape whose upper surface side is open, and a liquid outlet 5 is provided at the center of the lower surface side. The liquid outlet 5 has an upper opening edge chamfered in an R shape, and is formed in a tapered shape so that the inner diameter becomes smaller as it goes downward. Since the empty chamber 24 of the cock body 1 is tilted forward, the measuring instrument 2a is also tilted forward at the same angle. The weighing instrument 2a is attached in close contact with the cock body 1 by placing the upper end face on the lower end face of the cock body 1 and turning the ring body 22 to tighten the screw 28 so that the packing 29 is slightly crushed. . By rotating the ring body 22 in the reverse direction and removing it from the cock body 1, the measuring instrument 2 a can be separated below the cock body 1.
The lid 20 is detachably attached to the upper opening 19 of the cock body 1 with screws 45.

As shown in FIG. 1, the valve stem 3a is configured by inserting a resin shaft 31 into the center of a silicone rubber valve body 30, and in parallel with the forward tilt of the cock body 1 and the measuring instrument 2a. Move back and forth. The valve body 30 has a vertical interval between a first valve portion 7 that opens and closes the liquid outlet 5 from the meter 2a and a second valve portion 8 that opens and closes the liquid inlet 6 to the meter 2a. It is provided. The 1st valve part 7 and the 2nd valve part 8 are formed in the circular fin shape which thickness became thin as it went to the outer peripheral side, and can deform | transform flexibly. As shown in FIG. 1, in a state where the operation unit 4 is not operated, the valve stem 3a is pushed downward by the coil spring 23, and the first valve unit 7 is deformed so as to bend upward so that the liquid outlet 5 is The second valve portion 8 is closed from above and is spaced downward from the liquid inlet 6. Therefore, the cock body 1 and the measuring instrument 2a are filled with the liquid 32.
The valve body 30 has an accommodating portion 33 for the coil spring 23 at the upper portion, and a flange 34 is formed at the upper end portion. The flange 34 is sandwiched between the upper opening 19 of the cock body 1 and the lid body 20. It is. This prevents the liquid 32 from coming into contact with the coil spring 23. Between the flange 34 and the lid 20, a spacer 35 made of a resin having good slippage is provided. By providing the spacer 35 in this manner, the valve stem 3a and the operation unit 4 can be rotated around the central axis C.
The valve stem 3a protrudes upward from a hole 36 provided in the center of the lid body 20, and a hook portion 37 for connecting to the operation portion 4 is provided on the protruding upper portion.

  As shown in FIGS. 1 to 3, the operation unit 4 includes a connecting part 38 located on the lid 20, an arm part 39 that hangs downward from the connecting part 38, and both sides of the cock 9 from the lower end part of the arm part 39. And a pressing operation portion 40 extending rearward so as to straddle the rod. A horizontal bar 41 provided on the connecting portion 38 is attached to a hook portion 37 of the valve rod 3a.

Next, an operation method of the cock 9 will be described. As shown in FIG. 1, the valve rod 3 a is most lowered when the operation unit 4 is not operated, and the liquid outlet of the meter 2 a is deformed so that the first valve unit 7 is bent upward at this time. 5 is closed from above, and the second valve body 8 is in a position spaced downward from the liquid inlet 6 to the meter 2a. Therefore, the liquid 32 in the bottle 10 flows into the measuring instrument 2a from the liquid inlet 6 and accumulates in the measuring instrument 2a.
As shown in FIG. 8, when the glass 13 or the like is pressed against the pressing operation unit 40 of the operation unit 4, the operation unit 4 rotates around the upper horizontal shaft 41, and accordingly, the connection unit 38 of the operation unit 4 The lower edge tilts forward and pushes the lid 20, and the valve stem 3 a is pulled up by the action of the lever. Initially, since the first valve portion 7 is deformed so as to bend upward (see FIG. 1), the liquid outlet 5 of the meter 2a is the first valve portion 7 at the initial stage of raising the valve stem 3a. As shown in FIG. 8, after the second valve portion 8 blocks the liquid inlet 6 to the meter 2a, the first valve portion 7 becomes the liquid outlet of the meter 2a. It has come away from 5. The timing at which the first valve portion 7 is separated from the liquid outlet 5 may be substantially the same as the timing at which the second valve portion 8 closes the liquid inlet 6.
Thereafter, as shown in FIG. 9, when the pressing operation unit 40 of the operation unit 4 is pushed backward to the limit, the first valve unit 7 is separated upward from the liquid outlet 5 of the measuring instrument 2a, and the second valve unit 8 Closes the liquid inlet 6 to the meter 2a in a state of being bent downward. As a result, a certain amount of the liquid 32 accumulated in the measuring instrument 2a is poured from the liquid outlet 5 into the glass 13 or the like.
Thereafter, when the glass 13 or the like is released from the pressing operation unit 40 of the operation unit 4, the valve rod 3 a is lowered by the urging force of the coil spring 23, and the liquid outlet 5 of the measuring instrument 2 a is blocked by the first valve unit 7, Thereafter, the second valve portion 8 is separated downward from the liquid inlet 6 to the meter 2a, and the liquid 32 in the bottle 10 is metered from the connecting pipe 25 through the liquid inlet 6 as shown by an arrow 42 in FIG. Flows into the vessel 2a. At that time, instead of the liquid 32 flowing into the measuring instrument 2a, the air 43 in the measuring instrument 2a travels along the lower surface of the second valve portion 8 as shown by the arrow 44 in the drawing, and the connecting pipe 25 and into the bottle 10. As described above, the cock 9 has the cock body 1, the measuring instrument 2 a, and the valve stem 3 a tilted forward, so that the liquid 32 and the air 43 can be provided without providing a separate mechanism for introducing the air 43 into the bottle 10. Is replaced smoothly.

Further, as shown in FIG. 5, the cock 9 can be easily disassembled and cleaned for each part. The procedure for disassembling will be described. First, the ring body 22 is removed with a screw 28, and the measuring instrument 2a is separated downward from the cock body 1. Next, while pushing up the valve rod 3a with a finger from below, the horizontal rod 41 of the operation unit 4 is removed from the hook portion 37 of the valve rod 3a, and the operation unit 4 is separated. Next, the lid 20 is removed, the valve stem 3a is pulled upward from the cock body 1, and the spacer 35 and the coil spring 23 are separated from the valve stem 3a. Furthermore, the valve stem 3 a can be separated into a valve body 30 and a shaft 31.
When assembling, reverse the disassembly procedure. Thus, the cock 9 is hygienic because it can be easily disassembled and cleaned for each part.

  FIG. 11 shows a state in which the measuring instrument 2a is replaced with a measuring instrument 2b having a smaller capacity than that of FIG. The measuring instrument 2b has the same vertical dimension as that of the measuring instrument 2a shown in FIG. 1, but has a substantially cylindrical shape with a substantially constant diameter, and the capacity is reduced by the amount that does not swell on the outer peripheral side. The shape of the liquid outlet 5 is the same as that of the measuring instrument 2a in FIG.

In FIG. 12, the valve stem 3a is replaced with a valve stem 3b having a long length between the first valve portion 7 and the second valve portion 8, and the meter 2a is replaced with a length between the first valve portion 7 and the second valve portion 8. The state where it changed to the measuring instrument 2c corresponding to the height and having a long vertical dimension and a large capacity is shown.
13 uses a valve rod 3b having a longer length between the first valve portion 7 and the second valve portion 8 as in FIG. 12, and replaces the measuring instrument with a measuring instrument 2d having a smaller diameter and a smaller capacity than that of FIG. The state is shown.

  As described above, the cock 9 can be selected from two types of the short type 3a and the long type 3b, and the measuring instruments 2a, 2b, 2c, and 2d have two types of large and small for the respective valve rods 3a and 3b. Since it is prepared, by changing the valve rods 3a, 3b and the measuring devices 2a, 2b, 2c, 2d, the amount of one time of dispensing can be changed in four ways. Accordingly, it is possible to easily cope with the difference in the size of the container into which the liquid 32 such as the glass 13 or the mug is poured or to change the concentration of the alcohol.

As described above, in the cock 9, the first valve portion 7 blocks the liquid outlet 5 and the second valve portion 8 is spaced downward from the liquid inlet 6 when the operation portion 4 is not operated. When the operating portion 4 is operated to lift the valve rods 3a and 3b, the first valve portion 7 is separated from the liquid outlet 5 after the second valve portion 8 blocks the liquid inlet 6, so that the operating portion Whenever 4 is operated once, the liquid 32 can be accurately poured out by a fixed amount. Since the cock body 1, the measuring instruments 2a, 2b, 2c, 2d and the valve rods 3a, 3b are tilted forward, the replacement of the liquid 32 and the air 43 is smooth without providing a separate mechanism for introducing air. To be made. Furthermore, since the measuring instruments 2a, 2b, 2c, 2d can be separated downward from the cock body 1 and the valve rods 3a, 3b can be extracted upward from the cock body 1, they can be easily disassembled and cleaned. Since the first valve portion 7 and the second valve portion 8 can be flexibly deformed, the vertical stroke of the valve stems 3a and 3b is absorbed by the deformation of the first valve portion 7 and the second valve portion 8, and the liquid flow The timing at which the inlet 6 and the liquid outlet 5 are opened and closed is set to an optimum state, so that quantitative dispensing can be accurately performed.
In addition, the cock 9 can easily change the amount of the liquid 32 to be dispensed at one time by simply replacing the measuring instruments 2a, 2b, 2c, and 2d with different capacities.
Further, the cock 9 replaces the valve rods 3a, 3b with different lengths between the first valve portion 7 and the second valve portion 8, and replaces the measuring instruments 2a, 2b, 2c, 2d with different capacities. Thus, it is possible to change the amount of one-time dispensing more greatly.
The cock 9 is provided with a pressing operation unit 40 hanging downward from the operation unit 4, and the liquid 32 is poured out by pushing the pressing operation unit 40 backward with the glass 13 or the like. It is easier to operate than the one that pushes up the feeding pipe at the edge of the cup.

  The present invention is not limited to the embodiments described above. The forms of the cock body, the valve stem, the operation unit, and the like can be changed as appropriate. The cock of the present invention can be widely used for dispensing beverages and the like, including the dispensing of alcoholic beverages such as whiskey and shochu. A container such as a beverage to which the cock of the present invention is connected is arbitrary, and is not limited to a bottle but may be a plastic bottle or the like.
