Description

[Detailed description of the invention] The present invention relates to a simple detachable liquid dispensing tap that is attached to a container such as a barrel or a large can to dispense carbonated drinks such as draft beer in a gravity flow method. .

When carbonated beverages in a container are poured out using the gravity flow method, the internal pressure of the container is reduced, resulting in a reduction in the pouring speed or the inability to pour out, so to avoid this situation, an air flow path is provided in the container. When pouring, it is necessary to let outside air flow into the container.

However, if the airflow path is kept open all the time, the carbon dioxide gas dissolved in the beverage will escape and the original flavor will be lost, so the airflow path must be opened and closed each time it is poured.

The present invention was developed with this point in mind, and its main feature is that the main body has a built-in valve body in order to simultaneously allow atmospheric air to be introduced into the container and allow the internal liquid to flow naturally due to its own weight. The valve body is located outside the fluid container, and the valve body is operated by an opening/closing means located above the valve body, so that the liquid flow path and the air flow path can be opened and closed simultaneously with a single touch.

The present invention will be explained in detail below with reference to illustrated embodiments.

In this embodiment, the partition wall part 6, the spout nozzle part 15, and the valve body part 1 are
Although the valve-equipped nozzle 18 is integrally formed with the valve 6 and the flexible elastic body, the present invention is not necessarily limited to this.

Reference numeral 19 denotes a casing, which is composed of an upper casing 20 and a lower casing 21.
The main body 1 provided with a nozzle 2 and a valve-equipped nozzle 18 is housed inside this casing 19.

Reference numeral 22 denotes a valve opening/closing means for opening and closing the valve body part 13. This valve opening/closing means 22 has a lower end that fits into the valve body part 13 and an upper end that is movable up and down above the casing upper part 20. a spring 24 loaded between the upper stem 23 and the casing upper part 20 for urging the stem 23 downward; and a spring 24 for urging the stem 23 downward;
It consists of a bundle 25 pivotally attached to the upper end of 3.

The bundle 25 has both bases 26 having an inverted U-shaped cross section and this base 2.
The upper end of the stem 23 is pivotally connected to the base 26 by a pin 28, such as an arm 27 connected to the stem 27.

The bundle 25 moves the undulation system 23 up and down, and in order to make the undulation movement smooth, the base 2
A rounded portion 29 is formed at the lower corner of 6.

30 is a joint with two inner holes 31 and 32;
This joint 30 is connected to the liquid container 9 via the gasket 33.
It is attached to the outflow hole 34 formed on the bottom wall of the.

The inner hole 31 of the joint 30 is connected to the communication port 10 of the main body 1 through a communication W35, and the inner hole 32 is connected to the communication port 11 of the main body 1 through a communication pipe 36, and its upper end is connected to the uppermost layer in the liquid container 9. It is connected to the lower end of the communicating pipe 37 that reaches the terminal.

Reference numeral 38 denotes a mounting bracket for attaching the liquid pouring tap of the present invention to the bottom of the liquid container 9 as described above;
The lower part 21 of the casing is screwed to 8, and the joint 30 is fixed with a mounting ring 39.

Thus, the liquid container 9 equipped with the liquid pouring tap of the present invention
is placed on a saucer 41 supported by a stand 40.

At that time, a cold storage body 42 made of a container filled with refrigerant is provided between the liquid container 9 and the receiver 41, and the liquid container 9 is covered with a cold insulator 43 made of a heat insulating material.

The structure of the liquid pouring tap according to the present invention is as described above.

Next, its effects will be explained. In FIG. 1, when the bundle 25 is in the raised state shown by the solid line, the stem Δ23 is lowered by the downward biasing force of the spring 24, and the valve body 13 is lowered accordingly to open the inner hole 14. The liquid flow path A is closed by sealing.

At the same time, the valve body part 13 bends the partition wall part 6 slightly downward, and accordingly, the valve body part 16 slightly descends and the valve seat part 1
7 and the air flow path B is closed.

Next, when the bundle 25 is pushed down by hand into the prone state shown by the dotted line, the stem 23 rises against the downward biasing force of the spring 24, and accordingly, the valve body 13 rises and the inner hole 14 Open the liquid flow path A.

At the same time, the partition wall portion 6 that had been bent downward returns upward, and the valve body portion 16 rises slightly and the valve seat portion 17
to open the air flow path B.

Therefore, at this time, the liquid in the container 9 passes through the liquid flow path A and flows out from the pouring nozzle 15, and at the same time, the outside air enters from the lower opening 3 and flows into the uppermost layer of the container 9.

Next, when the hand holding the bundle 25 is released, the bundle 25 automatically returns to the raised state shown by the solid line due to the interaction between the rounded part 29 formed at the lower corner and the spring 24, and at this time, As mentioned above, the liquid flow path A
and air flow path B are closed at the same time.

As described above, since the liquid dispensing tap of the present invention opens and closes the liquid flow path A and the air flow path B simultaneously each time it is dispensed, this tap can be used to pour carbonated drinks such as beer in a gravity flow manner. When dispensing, the beverage can be dispensed extremely smoothly without slowing down the dispensing speed or being unable to dispense, and the airflow path B is closed except during dispensing to prevent air from escaping the beverage inside the container. The original flavor of the drink can be retained for a long time.

Incidentally, due to an increase in outside temperature or vibration, the carbonated beverage inside the container emits a large amount of carbon dioxide gas, which considerably increases the internal pressure of the container.

When the internal pressure of the container increases, the beverage may leak from the connection between each member in the liquid flow path A, the sealed portion between the valve body 13 and the inner hole 14, and the like.

In order to prevent this, as shown in FIG.
The outer edge of the lower end may be the thin portion 45.

By doing so, the thin wall portion 45 blows out the gas in the container which has reached a certain pressure or higher by its valve action, thereby lowering the container internal pressure and preventing the beverage from leaking.

When pouring beer, the pouring nozzle part 15 is deeply inserted into the mug to reduce foaming of the beer.
Jotsuki - Usually, it is poured along the inner wall.

Since the pouring tap of the present invention blows outside air into the air flow path B from the lower opening 3 of the main body 1 during pouring, at this time the pouring tap
If the spout nozzle part 15 is inserted too deeply into the
There is a risk that the foam from the beer in the inner upper layer may be blown in with the outside air.

In order to prevent this, the valve seat 17 must be removed as shown in FIG.
An intake inner opening 46 is formed in the main body 1 at a position below the intake opening 46, and an intake rising opening 47 is formed in the casing lower part 21 at a position facing the intake inner opening 46. may be positioned below the intake/external ports 46, 47.

By doing so, when pouring beer, outside air is sucked in from the intake/outside ports 46, 47, while the upper end of the jockey is positioned at the lower end of the rib 48, so that the beer foam in the upper part of the inside of the jockey is removed. It is possible to prevent air from being blown into the air flow path B together with outside air.
