Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to beer, cola, tomato juice, etc.
The present invention relates to a beverage container for mainly storing carbonated drinks and fruit juice drinks.

[Conventional technology]

As is well known, beer is sold in bottles and aluminum cans, but aluminum cans are increasingly used due to ease of handling. There are many types of this aluminum can, from a small capacity of about 200 ml to a large capacity of several liters. In small- to medium-capacity can containers, the upper end of the bottomed can body is fixed by covering it with a lid with an annular handle, pulling the annular handle to remove a part of the lid, and directly or beer from the opening. They are transferred to cups and drink. Also, in a large-capacity can, a small-diameter mouth is provided above a large-diameter body via a shoulder having a gradually narrowing inner diameter, and a male screw-shaped stopper is fitted around the outer periphery of the mouth. There is a type in which a female screw-shaped cap is screwed and caulked to the mouth to seal the mouth, and the cap is removed at the time of drinking, and the container is tilted and beer is poured into a cup or the like.

[Problems to be solved by the invention]

By the way, the beer in the above-mentioned container with a relatively large capacity may sometimes be left behind, but if you try to drink it later, it will be oxidized or carbonic acid will be lost,
It was bad and not very drinkable. This is because in the conventional container, air flows into the container as beer is poured out, so even if the spout is closed with a cap etc., carbon dioxide gas may escape into the new air entering the container. It is considered that the beer is oxidized by oxygen contained in fresh air. Such drawbacks are also present in containers for storing carbonated drinks such as cola containing carbonated carbonated drinks and beer as well as fruit juice drinks that are remarkably degraded by oxidation, especially in the case of large-capacity containers that are often left behind. Had been a problem.

Also, large containers are heavy if they contain contents,
It was cumbersome when tilting containers to dispense stored beverages.

Therefore, the present invention has been made based on the above circumstances, it is possible to easily and reliably pour the contents into a cup or the like,
It is an object of the present invention to provide a beverage container that can be deliciously stored without being oxidized or carbonated even when the contents are left unreacted.

Next, an example of a method for manufacturing the container of the present invention and a method for filling a beverage will be briefly described. First, while the container body 5 is manufactured in the same manner as before, the packings 18 and 25 having substantially the same diameter as the annular piece 19 are fitted to the adapter 3 from above and below, and the lower end of the adapter 3 is fitted to the opening 2 of the pouch 1. Adhering or fusing in communication. The packing 18 fitted from above is entirely in close contact with the upper surface of the annular piece 19, and has a plurality of small holes 21 opposed to the through holes 20 via the annular groove 17. Further, the lower packing 25 is fitted on the outer periphery of the thick portion 16 and contacts the lower surface of the annular piece 19. Then, the pouch 1 is put together in a small size,
At the same time, the adapter 3 is fitted into the mouth 6, and the annular piece 19 is brought into contact with the rim of the container body 5 via the packing 25. Then, the adapter 3 has the mouth 6 only at the thick portion 16.
Between the adapter 3 and the mouth 6 of the container body 5,
An air passage 7 communicating with the outside of the container body 5 through the through hole 20 and the small hole 21 of the packing 18 is formed.
And pouch 1. Thereafter, a predetermined amount of a beverage 27 such as beer is injected into the pouch 1 through the adapter 3. At this time, with the infusion of the beverage 27, the pouch 1 spreads to a state almost inscribed in the container main body 5, and the air between the pouch 1 and the container main body 5 is discharged through the ventilation path 7. Then, the spout 4 having the nozzle 13 and the holder 12 is screwed into the mouth 6. At this time, it is not necessary to mount the aerosol can 11 on the holder 12.

The container of the present invention has the above structure. At the time of drinking, the aerosol can 11 is attached to the holder 12 and the spout 4
When a cup or the like is placed at the tip of the nozzle 13 and the tip of the lever 31 is pushed down, the flow path 23 of the spout 8 opens only while the lever 31 is pushed down, and the aerosol can 11 passes through the through hole 22 and the through hole 22. The compressed gas filled between the container body 5 and the pouch 1 through the hole 20 and the ventilation path 7 crushes the pouch 1, and the beverage 27 in the pouch 1 is discharged from the channel 23 through the nozzle 13 to a cup or the like. I do. By inserting the straw 47 into the pouch 1, the contents at the bottom of the pouch 1 can be reliably discharged. Release the lever 31 and the coil spring 32
Lever 31 is pushed up by the urging force of the valve 31, the valve 24 connected to the lever 31 comes into close contact with the valve seat 33, closes the flow path 23, and the beverage 27
Stops pouring. Thereafter, when the drink 27 is left unreacted, the lever 31 is stored in a cool place or the like so as not to be pushed down. Here, since no new air flows into the pouch 1 even after the pouch 1 is opened, there is no possibility that the beverage 27 will lose carbonic acid or the beverage 27 will be oxidized.

Although the beer can container has been described in the above embodiment, the present invention can be applied to other carbonated beverages and juice-containing beverage containers, and the material of the container body 5 can be appropriately changed. As described above, a push button may be provided instead of the lever 31.

〔The invention's effect〕

In the beverage container according to the present invention, the aerosol can is mounted on the holder as described above, and the beverage in the container is poured out from the nozzle tip simply by pressing down the lever. And the beverage can be poured very easily.

In addition, the container of the present invention crushes the pouch containing the beverage by the compressed gas filled between the container body and the pouch, pours the beverage from the spout nozzle, and stops the spout when the spout is stopped. Because it is closed, new air does not flow into the pouch at the time of pouring and after the pouring, so that the beverage can be smoothly poured out. In this way, it is possible to prevent oxidation by the air that has newly flowed in after opening the package and the escape of carbonic acid contained in the beverage.

Further, the beverage is contained within the pouch and does not mix with the compressed gas that extrudes the beverage.

Therefore, in the container of the present invention, even if an undrinked drink occurs after opening, the remaining drink can be stored in a state almost the same as before opening, and can be tasted and drink later.
