Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a separation-type carbonated beverage extractor, and more particularly, a model for extracting the carbonated beverage in a container to the outside without causing a so-called gas releasing action using the gas pressure of a carbon dioxide cartridge having an internal volume of about 10 cc. The present invention relates to a type that removes a gas supply unit from a beverage extraction unit without gas leakage.
[0002]
[Prior art]
The present applicant has previously proposed a carbonated beverage extractor of the type disclosed in Japanese Patent Application Laid-Open No. 7-35954, in which a cap with a detachable carbon dioxide cartridge is attached to a container and carbonated beverage is extracted out of the container by the pressure of carbon dioxide gas. Yes.
[0003]
[Problems to be solved by the invention]
Containers targeted for this proposed carbonated beverage extractor have a large capacity of 2 to 3 liters, and are usually not drunk at a single time. After each use, the rest is refrigerated in a refrigerator or the like, resulting in several It is a common usage pattern to drink in divided times.
However, when the carbonated beverage is stored in a refrigerated state, the container can be stored upright in a pocket if it is a large refrigerator. However, the size of a general household refrigerator cannot be accommodated unless the container is laid down. When the extraction of carbonated beverages is stopped, the gas supply unit and the internal pressure of the container are balanced, so if the container is placed on its side, the liquid in the container flows back to the decompression unit through the check valve of the gas supply unit. , Causing the function to be impaired.
The present invention is intended to solve these problems.
[0004]
[Means for Solving the Problems]
The separation type carbonated beverage extractor according to the present invention includes a beverage extraction unit and a gas supply unit. The beverage extraction unit has a cap, a siphon tube, an on-off valve, and an extraction port. The cap has an attachment portion for the opening of the container, a gas introduction passage with a check valve, and a beverage outlet passage. The siphon tube has an upper end portion connected to the beverage lead-out path and a decompression extraction portion at the lower end. The on-off valve has a valve seat and a valve body in the beverage outlet path. One end of the extraction port opens outside the cap, and the other end communicates with the beverage outlet path on the downstream side of the valve seat.
The gas supply unit is separate from the beverage extraction unit, and is disposed in the main body, a gas cartridge mounting unit, a plug opening unit, a gas extraction unit, a decompression unit, a gas outlet, and the gas outlet, and the gas supply unit is uncoupled. It has a self-closing valve that closes the outlet (36).
When the gas supply unit is connected to the beverage extraction unit, the gas outlet is connected to the gas introduction path of the cap.
[0005]
The siphon tube and the decompression extraction unit of the beverage extraction unit of the present invention are put into this container through the opening of the container containing the carbonated beverage, and the cap is attached to the opening by the mounting unit. Generally, this attachment portion is a screw, but it may be a one-touch type such as a click mechanism.
[0006]
A gas cartridge filled with gas is attached to the mounting portion of the gas supply unit. This attachment may be after the gas supply unit is coupled to the beverage extraction unit. The volume of this cartridge is about 10 cc, and the gas is generally CO ₂ gas. The cartridge is opened by the opening portion when the attachment is completed. The opening portion is a needle-piercing type in the case where the cartridge is sealed with a sealing plate, and a push-bar type in the case of a refill-type sealing mechanism type.
[0007]
High-pressure gas flows out from the opened cartridge, is decompressed by the decompression section through the gas extraction section, and flows to the gas outlet. Since the self-closing valve is disposed at the gas outlet, the gas is prevented from flowing out by the self-closing valve.
[0008]
When this gas supply unit is coupled to the beverage extraction unit, the gas outlet is connected to the gas introduction path. When the pressure in the container is lower than the pressure reduced in the decompression section, the gas opens the check valve in the gas introduction path and enters the container to pressurize the surface of the carbonated beverage.
[0009]
This check valve prevents the gas in the container from flowing out when the gas outlet is separated from the gas introduction path during pressurization. Further, if the outer end of the gas introduction path is closed with a lid, it is possible to prevent foreign substances from entering and to some extent prevent gas leakage. When the pressure in the container and the pressure in the decompression section are balanced, the outflow of gas from the cartridge stops.
[0010]
When it is desired to take out the carbonated beverage, a container, for example, a cup is applied to the extraction port, and the on-off valve is opened. When a nozzle is connected to the extraction port, the container is applied to the tip of this nozzle. For the operation of the on-off valve, for example, a lever, a push button or a screw rod is employed. The beverage outlet path is opened by opening the on-off valve. Therefore, the carbonated beverage whose surface is reduced by the pressure of the gas in the container flows into the siphon tube through the decompression extraction unit, rises inside thereof, and is extracted into the container through the beverage outlet path from the extraction port.
If the on-off valve is closed, the beverage outlet path is closed and the beverage extraction stops.
[0011]
When the pressure in the container is lowered by the extraction of the beverage and becomes lower than the pressure in the decompression part of the gas supply part, the gas flows into the container from the decompression part by opening the check valve of the gas introduction path. This inflow continues until both pressures are balanced.
[0012]
When it is desired to stop drinking carbonated beverages and store the container in the refrigerator, the gas supply unit is separated from the beverage extraction unit. Since a check valve is provided in the gas introduction path of the beverage extraction unit, the outflow of gas in the container is always prevented, and even if the gas supply unit is separated from the beverage extraction unit, the gas in the container leaks to the outside. There is nothing. If the outer end of the gas introduction path is closed with a lid, foreign substances can be prevented from entering and gas can be prevented from coming out.
[0013]
Similarly, the gas outlet of the gas supply unit is also prevented from being opened by the self-closing valve when it is separated from the gas introduction path, and the outflow of gas is stopped. Therefore, even if the container is placed in the refrigerator in a lying state, the internal gas or carbonated beverage does not flow back to the gas supply unit. In addition, since the gas supply unit can be separated from the container, the bulk is reduced accordingly, and it is easy to secure the accommodation space.
[0014]
When the beverage is extracted and the container is empty, the gas supply unit is separated from the beverage extraction unit. Subsequently, the cap of the beverage extraction unit is removed from the opening of the container. In this state, only the beverage extraction part that is easily soiled can be washed, and it becomes hygienic.
[0015]
A carbonated beverage can be extracted as in the previous case by preparing a container filled with a beverage, attaching the beverage extraction unit to the container, and combining the gas supply unit with the beverage extraction unit. If the gas supply unit that has not used up the gas is used for the next extraction, the waste of gas can be saved.
[0016]
The gas supply unit and the beverage extraction unit may be coupled by a cap nut disposed on one of the gas outlet and the gas introduction path and a screw formed on the other.
In this case, the coupling between the gas supply unit and the beverage extraction unit becomes direct, and handling becomes easy.
[0017]
The gas outlet may be provided at an end of a tube extending from the main body. In this case, the coupling between the gas supply unit and the beverage extraction unit becomes indirect, and the degree of freedom in selecting the place where the gas supply unit is installed is increased.
[0018]
A valve rod is connected to the gas outlet, the self-closing valve is accommodated in the valve rod, the cap nut is loosely fitted to the valve rod, and the screw is an edge of the gas introduction passage of the cap Formed on the outer periphery, and by screwing the cap nut and the screw, the thrust bar in the gas introduction path moves through the self-closing valve so that the gas outlet is connected to the gas introduction path. Also good.
In this case, the self-closing valve can be easily arranged, and the gas supply unit and the beverage extraction unit can be easily coupled and separated by screwing the cap nut or unscrewing.
[0019]
The gas supply unit may include a hook that engages with a groove inside the joint curl portion of the container.
In this case, the gas supply unit can be suspended from the container, and there is no difficulty in finding the installation location of the gas supply unit.
[0020]

An elastic check valve 10 whose lower end is closed is press-fitted to the outer periphery of the cylindrical portion 41. The check valve 10 has a crack 42 formed at the lower end, and when a prescribed pressure is applied to the gas introduction path 11 from the outside, the crack 42 is opened and gas flows from the outside to the inside of the container 7. When the value is less than the specified value, the crack 42 is closed to prevent the gas inside the container 7 from flowing out.
[0029]
Instead of the crack 42, a hole may be formed in the side surface of the cylinder part 41 to close the lower end, and an elastic cylinder may be fitted into the cylinder part 41 to close the hole.
[0030]

When the pressure in the container 7 and the pressure of the decompressed gas are balanced, the gas flow stops.
[0031]
Since this gas pressure is applied to the liquid level of the carbonated beverage in the container 7, if the valve body 22 is separated from the valve seat 21 by the lever 24, the carbonated beverage in the container 7 flows in the decompression extraction unit 13 by the gas pressure. It flows uniformly through the passage gap 17, rises in the siphon tube 4, passes through the extraction port 6, and is extracted from the nozzle 28.
When the lever 24 is released, the valve element 22 is seated on the valve seat 21 by the spring 27, and the beverage extraction stops.
