[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispenser for dispensing a beverage in a keg by the pressure of carbon dioxide gas, and more particularly to a desktop dispenser which can be directly attached to a beverage keg placed on a table.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 5, a dispense head 1 is connected to a spear valve mounted on a base of a barrel T, as shown in FIG.
The dispensing head 1 is connected to a carbon dioxide gas cylinder 2 and a dispenser 3, and the carbon dioxide gas is injected into the barrel T from the carbon dioxide gas cylinder 2. As a result, the beverage in the barrel T is pressed downward by the carbon dioxide gas injected from the carbon dioxide gas cylinder 2 into the upper space in the barrel T, and a siphon pipe (not shown) of a spear valve attached to the mouth of the barrel T is provided. After being supplied to the dispenser 3 via the hose 4 and passing through the cooling coil 3A of the dispenser 3 to be cooled, it is poured from a tap 3B into a mug or the like.

[0003] In the case of draft beer, for example, such a facility for dispensing drinks is provided in a kitchen such as a beer garden or a pub, and draft beer is poured from a draft beer barrel into a mug in accordance with a customer's order. After that, they are brought to the customer's table.

[0004]

In recent years, there has been an increasing demand for the taste of draft beer. In particular, many people want to appreciate the taste of fresh draft beer.

However, as described above, in the method of pouring draft beer into a mug in a beer garden or the like and transporting the draft beer to a customer table, it takes time to receive an order, or after pouring from a draft beer barrel into a mug, until it reaches the customer table. There is a problem that it takes a long time for the beer to lose its foam, which is the life of the beer, and the customer cannot enjoy the fresh taste of the draft beer. Especially when the store is crowded during the peak of summer or when a group of large numbers enters the store at once, it is necessary to pour draft beer into many mugs at once and carry it to the customer's table. As a result, it has become increasingly difficult for customers to enjoy the draft beer while maintaining the fresh taste.

[0006] In addition, there is a demand on the store side to improve the efficiency of transporting orders and mugs, and to reduce labor costs. The present invention has been made in order to meet the above-mentioned demands, and has as its object to provide a tabletop dispenser that allows a customer to pour a drink such as draft beer into a mug by himself on a table. I do.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a table-top dispenser 10 according to an embodiment of the present invention, which is mounted on a draft beer barrel T.

The tabletop dispenser 10 has a dispensing head 11, a tap 12 having a pouring lever 12A, and a detachable carbon dioxide gas cylinder 13 which are integrally assembled. The main body is covered by a main body case 14. A cylinder cap 15 for accommodating and covering the carbon dioxide gas cylinder 13 is detachably attached to the main body case 14.

The tabletop dispenser 10 is mounted by connecting a dispense head 11 to a spear valve of a draft beer barrel T (the barrel shown is a 7-liter barrel) cooled in a refrigerator and stored in a cool case K in advance. You.

FIG. 2 is a side view showing the desktop dispenser 10 with the main body case 14 and the cylinder cap 15 removed. In FIG. 2, a frame 16 having a lower end fixed to the dispense head 11 stands upright so as to extend upward from the dispense head 11, and a tap 12 is fixed to the upper end of the frame 16. Further, a tap 1 is provided at the upper end of the frame 16.
A pressure reducing valve 17 is fixed to a rear portion of the pressure reducing valve 2, and a carbon dioxide gas cylinder 13 is detachably attached to a rear portion of the pressure reducing valve 17 from an obliquely lower rear side so that a gas outlet thereof faces upward. .

The tap 12 and the beer outlet 11A of the dispense head 11 are connected by a hose 18, and as described later, the beer pushed out of the draft beer barrel by the pressure of carbon dioxide gas is supplied from the beer outlet 11A through the hose. A plastic hose having a length of several tens of cm from the beer outlet 11A to the tap 12 and an inner diameter of 3.5 mm is used as the hose 18 which is to be sent to the tap 12 via 18. It is wound in a coil shape and stored in the main body case 14.

As described above, the reason why the dimensions of the hose 18 are determined and the coil 18 is wound in a coil shape is that when the flow velocity is high, the beer becomes turbulent in the pipe and bubbles are easily generated, and when the flow velocity at the tap outlet is high, the beer is generated. When poured into the mug, a large amount of foam is generated by violently hitting the wall of the mug, but the fluid resistance of the beer in the hose 18 is proportional to the length of the hose, inversely proportional to the diameter of the hose, and due to the curvature of the flow path. By increasing the flow rate, the fluid resistance in the flow path from the beer outlet 11A to the tap 12 is increased, so that foam is not excessively generated when beer is discharged.

The hose 18 is connected to the beer outlet 11A and the tap 12 via one-touch joints 19, respectively. As shown in FIG. 3, in the one-touch joint 19, an opening sleeve 19B is slidably fitted in one end side opening of the joint main body 19A, and a nail 19C is formed on an inner peripheral edge of the opening sleeve 19B. Have been. A cap nut 19D is provided on the other end of the joint body 19A, and the cap nut 19D is screwed into the cap nut 19D so as to be attached to the beer outlet 11A and the tap 12, respectively.

The hose 18 is inserted from the opening sleeve 19B side as shown by a chain line in FIG.
Fixed by C. When the hose 18 is detached, the pawl 19C is opened by pushing the opening sleeve 19B toward the joint body 19A, thereby allowing the hose 18 to be pulled out.

The liquid leak in the one-touch joint 19 is as follows.
It is prevented by the V seal 19E and the rubber packing 19F. As described above, the use of the one-touch joint 19 for connection of the hose 18 may deteriorate the quality of beer flowing through the hose 18 if the hose 18 becomes dirty.
If the hose 18 becomes very dirty, it can be easily replaced with a new one. In addition, in particular, in the desk-top dispenser 10, the dispensing head 11 does not have a dedicated cleaning port to reduce the size of the dispenser, as described later, so that the hose 18 can be easily replaced. Deterioration of beer quality can be prevented.

The pressure reducing valve 17 and the gas inlet 11B of the dispense head 11 are connected by a gas hose 20, and the carbon dioxide in the carbon dioxide gas cylinder 13 flows from the pressure reducing valve 17 through the gas hose 20 to the gas inlet 11B into the dispense head 11. Has been introduced.

As shown in FIG. 4, the dispense head 11 has a through hole 11C 'formed coaxially in the center of a housing 11C, and a cylindrical slider 11E having a beer flow hole 11e in the through hole 11C'. Is inserted vertically movably in the vertical direction, and a beer outlet 11A is formed at the upper end of the slider 11E.
The gas inlet 11B is formed on the side of 1C.

On top of the housing 11C, a handle 1 is provided.
1F is rotatably mounted by pivotally supporting one end thereof. Opposing protrusions 11G provided near the pivotal support of the handle 11F slide in grooves formed on the side portions of the slider 11E. By freely fitting, the slider 11E moves up and down with respect to the housing 11C with rotation of the handle 11F.

The handle 11F is provided with a slider 11E.
In the depressed position (the position indicated by the solid line in FIG. 4), the retractable protrusion 11F 'provided on the handle 11F engages with the engaging portion 11c of the housing 11C and is held at the depressed position. Have . Gas inlet 11
A check valve 11b is mounted in B. The check valve 11b is made of a material having a rubber-like flexibility, other, whatever if those having a check function may, or may be for example using Chakki ball.

The lower portion of the housing 11C has a conical shape whose diameter gradually increases as it goes downward, and a packing 11H is fixed to the lower end of the conical portion.

A flange 11E 'is formed on the outer periphery of the lower portion of the slider 11E, and a plurality of communication holes 11J are formed in the flange 11E' in parallel with the axial direction of the slider 11E.

A check ball 11K is provided in the beer circulation hole 11e of the slider 11E so as to allow only the fluid flow from the lower side to the upper side and prevent the flow in the opposite direction.

The pressure reducing valve 17 has a secondary pressure of 1.1 to 1.2 kg.
/ Cm ² is used. This is because by eliminating the need for pressure adjustment, a person who is not accustomed to operation can apply a constant pressure to the barrel.

The carbon dioxide gas cylinder 13 detachably attached to the pressure reducing valve 17 is a mini gas cylinder for a 7-liter barrel, weighing 160 g, having an outer diameter of about φ25 mm, and a length of 15 mm.
Although it is 0 mm, a mini-gas cylinder having an appropriate capacity can be mounted according to the size of the draft beer barrel T.

The tabletop dispenser 10 includes a pressure reducing valve 1
7 is connected to a spear valve (not shown) of the draft beer barrel T in a state where the handle 11F of the dispense head 11 is pulled up as shown by a chain line in FIG.

At this time, carbon dioxide gas introduced into the pressure reducing valve 17 from the carbon dioxide gas cylinder 13 and reduced in pressure so that the secondary pressure becomes 1.1 to 1.2 kg / cm ² is supplied to the gas in the dispense head 11 through the gas hose 20. Although introduced into the inlet 11B, the inner opening of the gas inlet 11B is closed by the outer peripheral wall of the slider 11E and is not introduced into the housing 11C.

After the table-top dispenser 10 is connected to the draft beer barrel T, when the handle 11F is pushed down, the slider 11E is lowered with respect to the housing 11C, and the lower end thereof pushes down the opening and closing packing of the spear valve, and the draft beer barrel T is opened. Open your mouth.

At this time, the lower opening of the slider 11E opens the inner opening of the gas inlet 11B (see FIG. 4). Thereby, the pressure reducing valve 17 is removed from the carbon dioxide gas cylinder 13.
The carbon dioxide gas supplied to the gas inlet 11B through the inlet is introduced into the housing 11C, and furthermore, the flange portion 11E '
Is introduced into the draft beer barrel T from the opening of the spear valve through the communication hole 11J formed in the beer.

The draft beer in the draft beer barrel T, when the tapping lever 12A is tilted down and the tap 12 is opened, flows through the siphon pipe of the spear valve and the beer circulation hole 11e of the slider 11E due to the pressure of the introduced carbon dioxide gas. It rises and is supplied to the tap 12 via the hose 18 from the beer outlet 11A, and is poured into a mug.

At this time, since the hose 18 has a sufficiently long length and is spirally wound, the pipe frictional resistance between the hose 18 and the beer flowing through the hose 18 is increased. Therefore, it becomes turbulent in the pipe and generates bubbles,
When the beer is poured into the mug, it is prevented from vigorously hitting the wall of the mug and generating a large amount of foam.

As described above, the tabletop dispenser 10 is provided with the carbon dioxide gas cylinder 13 for pouring draft beer, and is compactly configured. The draft beer can be poured into the mug by operating the tap 12 by himself.

When the draft beer barrel T is empty, the tabletop dispenser 10 moves the handle 11 of the dispense head 11.
After raising the slider F and raising the slider 11E to close the spear valve and the gas inlet 11B, the spoon valve of the draft beer barrel T is disconnected from the draft beer T by disconnecting the dispense head 11 from the spear valve of the draft beer barrel T.

After the residual pressure has been discharged, the tabletop dispenser 10 removed from the draft beer barrel T removes the carbon dioxide gas cylinder 13.
Is removed, and the tap 12 is further removed for cleaning. This washing is performed by a method such as inserting a water hose from below the dispense head 11. And after washing,
A new carbon dioxide gas cylinder 13 is installed and used.

The hose 18 is replaced when the inside thereof is extremely dirty and cannot be washed. At this time,
The hose 18 includes the dispense head 11 and the tap 1
2 is connected by a one-touch joint 19,
Easy to replace. That is, in FIG. 3, when the opening sleeve 19B is pushed into the joint body 19A, the claws 19C
Opens to disengage from the hose 18, and the hose 18 can be pulled out from the joint body 19A. Then, in this state, when the end of the new hose 18 is inserted into the joint main body 19A and the opening sleeve 19B is released, the claws 19C are closed and the hose 18 is fixed.

In the above embodiment, the case of pouring draft beer has been described. However, the desktop dispenser according to the present invention is also applicable to pouring of soft drinks, for example, soft carbonated drinks such as cola in addition to beer. it can.
