[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage container for mainly storing carbonated drinks such as beer, cola and juice.

[0002]

2. Description of the Related Art Conventionally, beer and the like have been sold in bottles and aluminum cans. However, beer or the like stored in a large container is sometimes left behind, and the remaining beer has a drawback that it is oxidized and deteriorates with time, and carbon dioxide is removed.

[0003] Therefore, a beverage container for preventing deterioration of the contents and removal of carbonic acid has conventionally been developed. FIG. 4 is a partially cutaway sectional view showing one embodiment of such a conventional container. Reference numeral 50 denotes a flexible pouch, and an opening 51 of the pouch 50 has an adapter 5 formed at a lower end of a housing 52.
3, and the main body of the pouch 50 is mounted inside the container main body 54. An air passage 55 communicating between the pouch 50 and the container body 54 is formed between the adapter 53 and the mouth 64 of the container body 54. The housing 52 has a holder 57 for holding an aerosol can 56 and a nozzle 58, and is fixed to an opening 64 of the container body 54. Further, a valve 59 biased by a spring body is provided at the center axis position of the housing 52 so as to be vertically movable, and an operation body 60 for pushing down the valve 59 is fitted to the upper end of the valve 59. At the lower end of the valve 59, a valve seat 62 for opening and closing the opening 63 of the housing 52 is provided.

Accordingly, the contents such as beer are filled in the pouch 50 mounted in the container body 54,
When the operating body 60 is pressed, the contact between the valve seat 62 and the opening 63 of the housing 52 is released. At this time, the aerosol can 5
Since the surface of the pouch 50 is constantly pressed by the pressure of the propellant continuously supplied from the nozzle 6, the contents in the pouch 50 vigorously pass through the nozzle 61 through the flow path 61 simultaneously with the opening operation of the valve 59. It flows out from 58.

[0005]

However, in such a conventional beverage container, the propellant ejected from the aerosol can 56 continuously connects the container body 54 and the pouch 50 from the time of installation of the aerosol can. Since the pouch 50 is supplied in between, the pressing force of the propellant always acts on the pouch 50. When the valve 59 is opened in such a state,
Pouch 50 already pressed by propellant
There was a disadvantage that beer and the like inside suddenly flowed out of the nozzle 58 to the outside.

The present invention has been made in view of such a conventional problem. In the case where contents such as beer are stored in a large container and taken out at the time of drinking, suddenly, when the valve is opened, the contents are suddenly changed. It is an object of the present invention to provide a beverage container having a simple structure while preventing the contents from flowing out to the outside.

[0007]

In order to solve this problem, the present invention provides an adapter at the mouth of a flexible pouch which is crushed by a propellant, and mounts the pouch in the container body and attaches the adapter. It is fixed to the mouth of the container body, forms a ventilation path between the adapter and the mouth, and supplies the propellant ejected from the aerosol can to the gap between the container body and the pouch via the ventilation path to press the pouch. A housing is fixed to the mouth of the container body, the housing includes a holder chamber for holding the nozzle and the aerosol can, and a valve adjacent to the holder chamber for opening and closing the flow path of the housing and controlling ejection of the contents. In addition, an operating body for stepwise pressing the valve head and the bottom of the aerosol can is provided at the upper part of the housing.

[0008]

The operation of the present invention having the above configuration will be described. As shown in FIG. 2, when the operating body is pressed, the valve pressing portion first comes into contact with the valve head, pushes down the valve, and opens the housing opening. However, at this time, the aerosol can pressing portion is not yet in contact with the bottom of the aerosol can (a gap h is formed as shown in FIG. 2 and h can be adjusted by the initial ejection state of the contents). In this state, even if the valve is open, the propellant does not squirt from the aerosol can,
The contents do not flow out of the pouch. Next, when the pressing of the operating body is advanced and the operating body is further lowered, as shown in FIG. 3, the aerosol can pressing section contacts the bottom of the aerosol can and opens the valve of the aerosol can. At this time, for the first time, the propellant is supplied from the aerosol can to the ventilation path, and is filled between the container body and the pouch. Then, the pouch is gradually pressed as the propellant increases, so that the contents in the pouch gradually flow out to the outside from the flow passage and the nozzle formed in the housing. That is, the momentum of the outflow of the contents gradually increases as the amount of propellant filled in the outer periphery of the pouch increases.

Then, when the pressing of the operating body is stopped, the aerosol can pressing portion and the bottom of the aerosol can first come off closely with time, and the outflow of the propellant stops. At this time, the housing opening is still in the open state, but the content of the pouch gradually decreases as the propellant decreases, and finally stops flowing. That is, in the beverage container according to the present invention, the pressing force acts on the pouch by the amount of the propellant supplied from the aerosol can, and the contents flow out. Therefore, unlike the conventional beverage container shown in FIG. 4, the pressing force by the propellant does not always act on the pouch. In addition, the valve body mounted in the valve chamber provided at the tip of the stem of the aerosol can is lowered by the ejection power of the propellant from the aerosol can, and the propellant is supplied to the ventilation passage through the valve chamber, and Filled between body and pouch.

[0010]

Next, the present invention will be described with reference to the drawings.
In the beverage container according to the present invention, a tubular adapter 5 is welded to the mouth 3 of the flexible pouch 2, the pouch body 2 is mounted in the container body 1, and the flange 8 of the adapter 5 is attached to the packing 23. And is fixed between the mouth 6 of the container main body 1 and the housing 7 via the. An air passage 4 is formed between the adapter 5 and the mouth 6 of the container body 1, and the air passage 4 communicates between the container body 1 and the pouch 2. Further, the ventilation path 4 communicates with the stem 24 of the aerosol can 12 through the valve chamber 9 of the housing 7. The valve element 10 mounted in the valve chamber 9 is easily opened by the propellant injection power. The flow of the propellant in the opposite direction is blocked by the valve element 10. Valve body 10
May be a valve body having any structure as long as it is opened by the propellant injection power, and may be a commonly used plate valve or the like.

The pouch 2 is made of a film having flexibility and gas barrier properties, and is formed in a shape substantially inscribing the container body 1. The film is usually a multi-layer film, and depending on the type of beverage to be stored, for example, a film in which a polyethylene film is laminated on both sides of an aluminum foil or a film of EVOH (a saponified ethylene vinyl alcohol copolymer) is used.

The housing 7 is formed in a cap shape, and is provided with a nozzle 22 protruding in a radial direction on a side surface.
On the opposite side of the nozzle 22, a holder chamber 11 for engaging and mounting a small aerosol can 12 is formed. In the embodiment, the aerosol can 12 is provided in reverse. Further, a valve chamber 25 is provided adjacent to the holder chamber 11, and a valve 18 for controlling ejection of contents is provided in the valve chamber 25.
Are provided vertically so as to block the flow path 26, and the spring 2
Energized by 0. When the valve seat 19 with packing attached to the lower end of the valve 18 comes into close contact with or separates from the housing opening 21, the housing opening 21 is opened and closed, so that the contents can flow out or are prevented from flowing in. can do. A female screw is formed at a lower portion of the housing 7 and is screwed to the mouth 6 of the container body 1.

Further, a feature of the present invention lies in the structure of the operating body 13 provided on the upper part of the housing 7 so as to be vertically movable. That is, when the valve pressing portion 16 contacts the valve head 17, a gap h is provided between the aerosol can pressing portion 15 and the aerosol can bottom 14. Then, even if the operating body 13 is pressed, the propellant does not immediately flow out of the aerosol can 12. That is,
The valve pressing portion 16 and the aerosol can pressing portion 15 formed on the operating body 13 have such a structure that the contact with the valve head 17 or the aerosol can bottom 14 by the pressing operation differs with time.

In the embodiment, the aerosol can 1
Liquefied gas (for example, Freon gas or the like) was filled in 2.
By using such a liquefied gas, the pressing force on the pouch 2 is integrated, and the pressing force on the pouch 2 is stabilized. Compared with a conventional case using a compressed gas (for example, carbon dioxide gas), a pressure regulating valve is not required and the structure of the entire apparatus is simple, so that the apparatus can be manufactured at low cost. Further, by setting the capacity of the liquefied gas to 30 cc or less, the application of the High Pressure Gas Control Law can be excluded.

As described above, according to the present invention, when beer or the like is stored in a large container, the contents of the beer or the like suddenly flow out when the valve is opened as in the prior art, and the clothes, etc. There is no danger of soiling. Further, since the structure is simple and the number of parts is small, there is an effect that it can be manufactured at low cost.
