Description

Description: TECHNICAL FIELD The present invention relates to an improvement of a beer quantitative dispensing device that dispenses a fixed amount of beer into a container such as a jug.

[Prior Art] In a conventional beer dispensing device A, as shown in FIG. 1, a dispensing faucet c is usually attached to a support b that is vertically installed on a support base a such as a counter. For the spout c,
A piston e that slides back and forth in the main body cavity of the spout faucet c by turning the lever d back and forth (left and right in FIG. 1) is provided, and the piston e has a base end side of the spout faucet c. The valve shaft 20 of the valve body 2 inserted in the valve chamber 1 formed in
As a result, by holding the lever d in the upright posture, the valve body 2 collides with the valve seat 3 and shuts off the communication between the spouting conduit 4 in the spouting faucet c and the valve chamber 1. From this state, by tilting the lever d forward (to the left in FIG. 1) and pushing the valve shaft 20 backward, the valve body 2 is moved to the valve seat 3 as shown in FIG.
The valve body 2 is fitted so as to slide in the axial direction with respect to the valve shaft 20 so that the pouring pipe line 4 and the valve chamber 1 are in communication with each other. A spring 22 provided between the screw 21 provided at the rear end and a spring 22 is urged so as to push it forward, and when the lever d in an upright posture is tilted rearward, the valve body 2 in the closed position is pushed. Is left in that position, the valve shaft 20 moves forward with respect to the valve body 2 against the bias of the spring 22, and a small hole opened in the fitting portion of the valve shaft 20 with the valve body 2.
As shown in FIG. 3, 23 is exposed on the side of the outlet pipe 4, and the valve chamber 1
And the pouring output line 4 communicate with each other through the small hole 23 which is the open end of the communication passage opened at the center of the screw 21 at the rear end of the valve shaft 20 and the axial center of the valve shaft 20. Is configured so that

Then, by this, the base end side of the spout faucet c is filled with beer and pressurized to a constant pressure in the tank T.
If the valve body 2 is connected to the valve seat 3 via the conduit P, the valve body 2 is pressed against the valve seat 3 by the pressure of beer flowing into the valve chamber 1,
When the lever d is tilted forward from this state, beer is discharged from the pouring faucet c, and when the lever d is tilted backward, beer spouts from the small hole 23, resulting in a very small amount. By pouring out in the form of cream in which small air bubbles gather, it becomes in the form of cream in which extremely fine small air bubbles gather and is discharged from the pouring faucet c.

Therefore, this conventional means places a container f such as a jug below the spout faucet c, tilts the lever d forward, and when the beer is poured to a predetermined level in the container f, returns the lever d and then By tilting the lever d later, the bubbles of beer in a state where extremely fine small bubbles are gathered are poured out onto the liquid surface of the beer poured into the container f.

[Problems to be Solved by the Invention] However, this means is operated by operating the lever d.
It is difficult to dispense a certain amount of beer while visually observing the amount of beer to be dispensed to the valve body 2 provided in the dispensing faucet c.
Since a mechanism for bubbling beer into small bubbles is incorporated, a member that forms a small gap such as the spring 22 around the valve body 2 is provided, and the lever d is tilted forward to prevent bubbles. When the liquid beer is about to be poured out into the container f, bubbles are inevitably generated, and the beer liquid level below the bubbles in the container f is kept at a constant level. I have a difficult problem to pour out my beer.

In addition, the pipe for pouring out beer is provided with an automatic opening / closing valve, and a bypass pipe that straddles the automatic opening / closing valve is branched, and a bypass valve is provided in the line of the bypass pipe to pour out the foamed beer. There is also a means for automatically controlling.

However, this means is that the beer is poured into a container such as a jug of the first cup, which is performed in a state where the inside of the pipe for pouring beer and the tap for connecting the beer and the bypass pipes is clean. Weighing out a predetermined amount and placing the creamy beer foam in which fine small bubbles gather on the liquid surface of the beer will be done cleanly, but once the fine foam is passed through the bypass pipe. When pouring into the container after the second cup after pouring, when pouring liquid beer without bubbling from the pouring faucet, the beer will be in a frothy state, There is a problem that it is difficult to pour out a certain amount of beer so that the liquid level of the beer below is at a certain level.

The present invention has been made in order to solve these problems that have occurred in the conventional means, in order to be able to accurately pour a certain amount of beer into the container, first, Accurately pour the liquid beer to a certain level, then on the beer level in the container,
It is an object of the present invention to provide a new means by which beer bubbles can be arranged in the form of cream that is extremely fine and small.

[Means for Solving the Problems] The present invention has been made based on the results obtained by conducting various studies and experiments in order to achieve the above-mentioned object.

That is, beer has a characteristic that bubbles are called bubbles, and when pouring beer into a container, when bubbles are adhered to the wall surface of the container, beer should be carefully poured so as not to foam liquid beer. But, foaming will start to occur.
And, from this, even if the beer is poured into the container f such as a jug in a froth-free state from the tap spout c provided in the draft, the cause of the beer being infused by necessity is The spout c
In order to raise the fine bubbles on the liquid surface of the beer poured into the container f, it is also used as a bubble discharge nozzle for discharging the fine bubbles, so that the previous bubble discharge on the inner surface of the vessel wall of this spout faucet c. Since I noticed that it was due to the adhesion and remaining of fine bubbles in the case of, the branch line for foaming was branched from the conduit P that leads the beer to the tap faucet c, and A valve mechanism for foam discharge is provided on the way, a foam discharge nozzle formed separately from the discharge faucet c is provided on the tip side, and the bubble discharge nozzle is arranged in parallel with the discharge faucet c. Liquid beer and bubbling beer were poured into the container through each separate conduit and spout, after pouring the beer into the container in a predetermined amount in a liquid state without bubbling. , Pour so that the creamy beer that is finely foamed on the liquid surface of the beer rises Go is by results.

From this, in the present invention, as a means for achieving the above-mentioned object, the beer that is pressurized on the base end side of the spout that is supported on the upper end side of the pillar installed on the support base is pressed. Is connected with a conduit that communicates with the tank that is filled with, and the spout has a valve body that switches between a valve open state and a valve closed state by the operation of a lever. The branch is provided with a branch, and a bubble outlet nozzle formed separately from the pouring faucet is provided at the tip side of the duct, and the foam ejecting nozzle is provided along the outer surface of the pouring faucet. The present invention proposes a beer metering device which is arranged in parallel with a faucet.
