[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 supplies a propellant ejected from an aerosol can to a pouch in a container body through an air passage, and expands the content of the pouch. A spouting beverage container, wherein a housing is attached to the mouth of the container body, the housing includes a holder chamber for holding a nozzle and an aerosol can, and is adjacent to the holder chamber, and opens and closes a flow path of the housing to open the contents. And an operating body for stepwise pressing the head of the valve and the bottom of the aerosol can in an interlocked manner at the top of the housing.

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 contacts the valve head,
Depress the valve to open the housing opening.
However, at this time, the pressing portion of the aerosol can has not yet contacted the bottom portion of the aerosol can (a gap H is formed as shown in FIG. 2. The gap H can be adjusted by an initial outflow condition of the contents). In this state, even when the valve is open, the propellant does not squirt out of the aerosol can, so that the contents do not flow out of the container body. Further, when the operating body is further pressed and the operating body is lowered, the aerosol can pressing part contacts the bottom of the aerosol can and opens the valve of the aerosol can as shown in FIG. At this time, the propellant is filled from the aerosol can into the container body and the pouch for the first time. Then, the pouch gradually expands with the increase in the propellant, and the content is pushed out and pressed by the expansion pressure, and flows out of the container body.

Next, when the pressing of the operating body is stopped, the aerosol can pressing portion and the bottom of the aerosol can first come loosely with time, the outflow of the propellant stops, and the volume of the pouch 2 increases and decreases thereafter. Not sure. At this time, the housing opening is in the open state, but after the content has flowed out to the outside by a certain amount, the pressure decreases, so the momentum flowing out to the outside gradually decreases, and finally the flow stops. . That is, the beverage container according to the present invention, the amount of the propellant supplied from the aerosol can, the pouch expands,
The content is pushed away by the expanded amount and flows out. Therefore, unlike the conventional beverage container shown in FIG. 4, the pressing force by the propellant does not always act on the pouch. The valve body mounted in the valve chamber provided at the tip of the stem of the aerosol can drops as shown in FIG. 3 due to the pressure of the propellant ejected from the aerosol can, and the propellant passes through the valve chamber and is ventilated. It is supplied to the road and filled in the pouch.

[0010]

Next, the present invention will be described with reference to the drawings.
In the beverage container according to the present invention, the opening 3a of the flexible pouch 2 is welded to the opening 5a of the adapter 5 hanging down from the housing 4, and the pouch 2 is suspended in the container body 1.
A ventilation path 6 is formed in the adapter 5, and the ventilation path 6 communicates with the valve chamber 7, and further communicates with the aerosol can 9 via the valve chamber 7. The valve element 8 mounted in the valve chamber 7 is easily opened by the pressure of the propellant ejected from the aerosol can 9. The valve element 8 prevents the flow of the propellant in the reverse direction. As shown in FIG. 3, the valve element 8 may have any structure as long as it has a function of releasing the outlet of the stem 9 a by the ejection pressure of the propellant from the aerosol can 9. It may be a commonly used plate valve or the like.

The pouch 2 is made of a multilayer film having flexibility and gas barrier properties, and is made of aluminum foil, EVOH so that the propellant does not mix with the contents in the container body.
(A saponified ethylene vinyl alcohol copolymer), nylon and the like are laminated inside.

The housing 4 is formed in a cap shape, and a nozzle 15 protruding in a radial direction is attached to a side surface thereof. On the opposite side of the nozzle 15, a holder chamber 19 for mounting and fixing a small aerosol can 9 is formed. In the embodiment, the aerosol can 9 is provided in reverse. further,
A valve chamber 12 is provided adjacent to the holder chamber 19, and a valve 16 for controlling ejection of contents is provided in the valve chamber 12.
Are provided vertically so as to shut off the flow path 14, and the spring 1
3 energized. When the valve seat 18 with packing attached to the lower end of the valve 16 comes into close contact with or separates from the housing opening 17, the housing opening 17 is opened and closed, and the outflow of the contents becomes possible or the outflow is prevented. can do.

Further, a feature of the present invention lies in the structure of the operating body 20 which is provided on the upper part of the housing 4 so as to be vertically movable. That is, when the valve pressing portion 11 abuts on the valve head 16a, a gap H is provided between the aerosol can pressing portion 10 and the aerosol can bottom 9b as shown in FIG. Then, even if the operating body 20 is pressed, the propellant is not immediately ejected from the aerosol can 9. That is, the valve pressing portion 11 and the aerosol can pressing portion 10 formed on the operation body 20 are in contact with the valve head 16a or the aerosol can bottom 9b by the pressing operation.
Each of them has a structure different from time to time.

In the embodiment, the aerosol can 9
The inside was filled with a liquefied gas (for example, Freon gas or the like). By using such a liquefied gas, the pressing force on the contents in the container body 1 is made constant, and the ejection pressure of the contents 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 leaks when the valve is opened as in the prior art. There is no risk 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.
