Description

  This device is provided, for example, in a beer spout of a container containing beer, and is dispensed with a function of maintaining beer in a state where it is fed to a cooling device during store operations and switching to a non-delivery state when the store is closed Regarding the head.

For beer or carbonated beverages, it is necessary to apply a gas pressure in the container to suppress the outflow of gaseous components from the beverage. For this reason, a dispensing head is provided at the beverage outlet of the beverage container, the beverage is poured out of the container via the dispensing head, the dispensed beverage is fed to a cooling device called a dispenser, and the beverage cooled by the cooling device is The form which inject | pours into a cup etc. and sells is taken.
This is shown in FIG. In the figure, 10 is a gas cylinder, 20 is a beverage container, 30 is a dispensing head attached to the mouth of the beverage container 20, and 40 is a cooling device. The gas cylinder 10 is generally filled with carbon dioxide gas. The carbon dioxide gas is applied to the dispense head 30 through the pressure reducing valve 11, and the carbon dioxide gas is applied to the beverage container 20 by the operation of the dispense head 30 and the non-application state. Be controlled.

The dispensing head 30 is connected to the upper end of a siphon tube 21 attached to the beverage container 20 and includes a control valve that switches between applying a gas pressure toward the beverage container 20 and a non-applying state. The control valve is operated by a lever, and the gas pressure is applied to the beverage container 20 from the gas cylinder 10 during the opening of the store, and the beverage container 20 is opened each time the dispensing cock 41 provided in the cooling device 40 is opened. Then, the beverage is pushed up by gas pressure and poured into a container 50 such as a mug.
The dispense head 30 is always kept open during the store operation, and the gas pressure in the beverage container 20 is maintained at a constant value.

  While the store is open, the dispense head 30 is kept open as described above and the gas pressure is applied to the beverage container 20 from the gas cylinder 10, but when the store is closed, the dispense head 30 is closed. The gas pressure from the gas cylinder 10 is shut off. In this state, the inside of the beverage container 20 is maintained at the atmospheric pressure given from the gas cylinder 10 by the valve of the dispense head 30. When opening the store the next day, the valve of the dispensing head 30 is operated again to apply gas pressure from the gas cylinder 10 to the beverage container 20 so that the beverage can be poured out.

  Here, the structure of the dispensing head 30 and the siphon tube connected to the dispensing head 30 will be briefly described. As shown in FIG. 5, the dispensing head 30 has a double tube structure including an outer tube 31 and an inner tube 32. O-rings 33A and 33B are mounted between the inner tube 32 and the outer tube 31, and a region sandwiched between the O-rings 33A and 33B is kept airtight. A small-diameter portion 32 </ b> A is formed on the peripheral surface of the inner tube 32 at this airtight portion. A branch pipe 31A communicating with the outside is provided in the outer pipe 31 so as to face the small diameter portion 32A, and a gas pressure is applied from the gas cylinder 10 to the branch pipe 31A.

In a state where the small diameter portion 32A is disposed at a position surrounded by the O-rings 33A and 33B, the gas applied through the branch pipe 31A is maintained in a state in which neither leaks. On the other hand, when the inner tube 32 moves downward by the operation of the lever 34 and the small diameter portion 32A moves below the lower O-ring 33B, the gas applied to the branch tube 31A is separated from the outer tube 31. It is ejected downward through a gap between the inner tube 32 and applied to the beverage container 20.
Next, the structure of the siphon tube 21 will be described. As shown in FIG. 6, the siphon tube 21 includes a first valve 22 and a second valve 23. The first valve 22 and the second valve 23 are always biased upward by springs 22A and 23A, and are closed. The state is maintained (see FIG. 6A).

  The first valve 22 is engaged with the lower end of the inner tube 32 provided in the dispensing head 30 shown in FIG. 5, and when the inner tube 32 moves downward by the operation of the lever 34, the first valve 22 moves downward from the inner tube 32. The first valve 22 is moved downward against the biasing force of the spring 22 </ b> A in response to the biasing force to face. By this movement, a first gap 24 (see FIG. 6B) is formed between the first valve 22 and the second valve 23, and a beverage flow path is formed by the first gap 24. The beverage spouted through the first gap 24 is injected into the hollow portion of the inner tube 32 through the notch 32B shown in FIG. 5, rises upward, and is carried to the cooling device 40 through the hose 37.

On the other hand, when the downward movement of the inner pipe 32 further proceeds, the first rubber packing 35 (see FIG. 5) covering the outer side of the inner pipe 32 is engaged with the step portion 23A (see FIG. 6B) of the second valve 23. The beverage flow path and the gas flow path are shielded.
When the movement of the inner pipe 32 further proceeds, the second valve 23 starts to move downward against the biasing force of the spring 23B, and a second gap 26 is formed between the second valve 23 and the holder 25 ( (See FIG. 6C). The second gap 26 acts as a gas flow path, and the gas ejected from the dispensing head 30 is applied to the inside of the beverage container 20 through the hole 27. The dispense head 30 is provided with a second rubber packing 36 at the lower end of the outer tube 31, and the second rubber packing 36 is pressed against the step portion 25 </ b> A of the holder 25 of the siphon tube 21 to connect the gas flow path and the outside. Shield between. The holder 25 and the dispense head 30 are locked by a vanette mechanism constituted by a claw 25B provided on the inner periphery of the holder 25 and a claw 31B (see FIG. 5) provided on the outer periphery of the outer tube 31 of the dispense head 30. The upper end portion of the inner pipe 32 is a beverage delivery outlet, and a hose 37 leading to the cooling device 40 is connected. As is clear from the above description, the hollow portion of the inner tube 32 acts as a beverage pouring path, and the gap between the outer tube 21 and the inner tube 22 acts as a passage through which gas pressure is applied. The small diameter portion 32A formed in the pipe 32 and the O-ring 33B act as a control valve for opening and closing the gas pressure application passage.

As described above, in this type of beverage dispensing apparatus, the beverage staying in the pipe line from the dispensing head 30 through the cooling device 40 to the dispensing cock 41 is left in a state where no gas pressure is applied during closing. Although there is no portion that comes into contact with air in the pipe line between the dispensing head 30 and the dispensing cock 41, the pressure of the beverage staying in this portion is left low, and the carbonic acid or gas component contained in the beverage is vaporized. And the so-called unintentional state. For this reason, at the beginning of the store opening, the beverage staying in the cooling device 40 must be discarded, resulting in waste.
In addition, in summer or stores where heating is good, there is a risk that the beverage staying in the store will be altered. For this reason, as a regular handling method, the dispense head 30 is replaced with a washing barrel containing washing water when the store is closed, and the washing water is poured out from the washing barrel using gas pressure, and the washing water is cooled by the cooling device 40 through the hose 37. The beverage remaining in the hose 37 and the conduit in the cooling device 40 is discharged with the cleaning water, and the operation of cleaning the conduit with the cleaning water is required.

However, every time the store is closed, the dispensing head 30 must be replaced with a washing barrel every day, and the operation of washing the pipeline with washing water must be performed. For this reason, generally, there are many cases in which a beverage poured out at the beginning of opening a store is disposed of and a method of wasting beverages is often used. The pipe for cooling in the cooling device 40 is relatively long, and therefore, the amount of beverage that is wasted is large, which is about one full of a mug. When this amount of beverage is discarded at a large number of restaurants, the total amount becomes large and wasteful.
An object of the present invention is to provide a dispensing head that can draw out a beverage staying in a cooling device with a simple operation, and thus can draw out a fresh beverage when the store is closed.

  In the first embodiment of the present invention, a gas pressure application passage is connected to the upper end of a siphon tube that is suspended and supported from the outlet of the beverage container toward the bottom of the beverage container, and applies a gas pressure toward the beverage container. A beverage pouring path for pouring the beverage from the inside of the beverage container to the outside through the siphon tube, a beverage feeding port for feeding the beverage poured through the beverage pouring path to the beverage cooling device, and a gas pressure applying passage A dispensing head provided with a control valve that switches between a state in which a gas pressure is applied to a beverage container and a state in which a gas pressure is not applied is communicated with a beverage dispensing path and applies a gas pressure to the beverage dispensing path from the outside We propose a dispense head with a gas pressure supply pipe.

In the second embodiment of the present invention, a structure is proposed in which a gas pressure supply pipe that communicates with a beverage dispensing path and applies a gas pressure to the beverage dispensing path from the outside is added on the beverage delivery port side of the dispensing head.
In the third embodiment of the present invention, a structure in which a gas pressure supply pipe is connected to the beverage dispensing path on the connection point side with the siphon tube from the control valve of the dispensing head and applies gas pressure to the beverage dispensing path from the outside. suggest.

According to this device, since the gas pressure supply pipe connected to the dispensing head of the dispense head is added to the dispense head, a pipe for supplying gas pressure via the gas cock is provided to the gas pressure supply pipe. After the control valve provided in the gas supply path of the dispense head is operated to be closed, the gas pressure is applied to the beverage container, the gas cock is opened, and the gas pressure is applied to the beverage dispensing path. By doing so, it is possible to discharge all the beverage remaining in the pipe line in the cooling device from the dispensing head to the dispensing cock.
Therefore, all the beverages staying in the cooling device can be extracted only by performing the operation of closing the dispense head and the operation of opening the gas cock. Therefore, since it is possible to easily extract the beverage from the cooling device even when the store is busy, it is possible to extract the beverage in a fresh state, so that the beverage is not wasted and wasted. It can be prevented from occurring.

The dispense head according to this device applies gas pressure to a beer barrel, pours beer from the beer barrel by gas pressure, cools the poured beer with a cooling device, and provides the cooled beer to customers. It is suitable for application to a dispensing device.
In this case, since the dispense head is provided with a second gas pressure supply pipe communicating with the beverage pouring path separately from the normal gas pressure supply pipe, by connecting a gas cylinder to the gas pressure supply pipe through the gas cock, When the gas cock is opened, the beverage staying in the beverage passage leading to the cooling device can be pushed out by the gas pressure. The effort required here is only the operation of closing the dispensing head and the operation of opening the gas cock.

  FIG. 1 shows a first embodiment of the present invention. In FIG. 1, the structure of the operation lever 31 is simply shown, but the structure is the same as that described in FIG. 5, and the inner tube 32 is moved up and down. This device is characterized by a structure in which a gas supply pipe 38 is added to a beverage pouring path constituted by an inner pipe 32. In particular, the first embodiment has a structure in which a gas pressure supply pipe 38 communicating with the beverage dispensing path between the valve position of the dispensing head 30 and the beverage delivery outlet is added. The gas pressure supply pipe 38 is connected to the pressure reducing valve 11 through the hose 13 and the gas cock 12, and the gas cock 12 is operated in an open state so that the gas pressure can be applied to the beverage dispensing path.

In order to control the gas cock 12 to open, first, the control valve of the dispensing head 30 is operated to the closed state (the small diameter portion 32A of the inner tube 32 described in FIG. 5 is moved to the upper side from the position of the O-ring 33B). By opening the gas cock 12 after operating the head 30 in the closed state and further opening the dispensing cock 41, the gas pressure does not go to the beverage container 20 but goes to the cooling device 40 through the hose 37 and stays in the cooling device 40. The drinking beverage can be discharged from the dispensing cock 41.
Therefore, according to this device, since the hose 13 and the gas cock 12 are connected, the remaining beverage can be discharged only by performing the operation of the dispensing head 30 and the operation of opening the gas cock 12 and the dispensing cock 41. Drinks can be withdrawn every day even during busy times when the store is closed. Since the extracted beverage is fresh, it does not have to be disposed of in vain, and the effect of reducing the waste of resources generated by disposal in many stores can be obtained.

FIG. 2 shows a second embodiment of the present invention. The second embodiment shows a case where the gas pressure supply pipe 38 is added to the connection point side with the siphon pipe 21 from the branch position of the branch pipe 31A. That is, the case where the outer pipe 31 is extended downward from the position of the O-ring 33B and the gas pressure supply pipe 38 is branched and added to this extended portion is shown.
Even if the expansion is performed in this way, if the dispensing head 30 is operated to the closed state, the first valve 22 and the second valve 23 provided on the siphon tube 21 side in conjunction with this will be described. Since the gas cock 12 is opened in this state, the gas pressure is applied to the beverage dispensing passage, pushes up the beverage from the notch 32B (see FIG. 5) formed at the lower end of the inner pipe 32, and reaches the cooling device 40. The beverage can be discharged from the dispensing cock 41.

FIG. 3 shows a third embodiment of the present invention. The third embodiment shows a case where an attachment 39 is attached to the upper end of the inner pipe 32 and a gas pressure supply pipe 38 is added by the attachment 39. That is, the attachment 39 having a branch pipe is attached to the upper end of the inner pipe 32. The branch pipe acts as a gas pressure supply pipe 38. A gas cock 12 is mounted on the gas pressure supply pipe 38, and the gas pressure can be intermittently connected with the gas cock 12. Therefore, in this case, the gas pressure supply pipe 38 may be directly connected to the pressure reducing valve 11 by the hose 13.
Also in this embodiment, if the gas cock 12 is opened with the dispense head 30 in the closed state, all the beverages remaining in the beverage passage from the dispense head 30 to the cooling device 40 can be discharged from the dispensing cock 41.

  The dispensing head according to this device is used for a draft beer pouring device used in restaurants.
