Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a beverage container that mainly stores carbonated drinks such as beer, cola or juice.

[0002]

[Prior Art]

 Conventionally, beer and the like are sold in bottles or aluminum cans filled with them. However, beer and the like stored in a large container are sometimes left undrinked, and the unfilled beer has a drawback that it is oxidized and deteriorated with time, or carbonic acid is removed.

Therefore, a beverage container for preventing deterioration of the contents and loss of carbonic acid has been developed. FIG. 4 is a partially cutaway sectional view showing an example of such a conventional container. Reference numeral 50 denotes a flexible pouch, the mouth portion 51 of the pouch 50 is welded to an adapter 53 formed at the lower end of the housing 52, 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 opening 64 of the container body 54. The housing 52 has a holder 57 for holding the aerosol can 56 and a nozzle 58, and is fixed to the opening 64 of the container body 54. Further, a valve 59 urged by a spring body is vertically movable at a central axis position of the housing 52, and an operating body 60 for pushing down the valve 59 is fitted to an upper end of the valve 59. A valve seat 62 that opens and closes the opening 63 of the housing 52 is provided at the lower end of the valve 59.

Therefore, when the contents such as beer are filled in the pouch 50 mounted in the container main body 54 and the operating body 60 is pressed, the valve seat 62 and the opening 63 of the housing 52 come into contact with each other. Come off. At this time, since the surface of the pouch 50 is constantly pressed by the pressure of the propellant continuously supplied from the aerosol can 56, the contents in the pouch 50 flow vigorously at the same time when the valve 59 is opened. It flows out of the nozzle 58 through the passage 61.

[0005]

[Problems to be solved by the device]

 However, in such a conventional beverage container, the propellant ejected from the aerosol canister 56 is continuously supplied between the container body 54 and the pouch 50 since the aerosol canister was installed. The pressure of the propellant always acts on 50. When the valve 59 is opened in such a state, there is a drawback that beer or the like in the pouch 50 already pressed by the propellant suddenly flows out from the nozzle 58.

The present invention has been made in view of such a conventional problem, and when the contents such as beer are stored in a large container and taken out at the time of drinking, a sudden discharge occurs when the valve is opened. The purpose of the present invention is to prevent the contents from leaking to the outside and to provide a drinking container having a simple structure.

[0007]

[Means for Solving the Problems]

 In order to solve this problem, this invention attaches an adapter to the mouth of a flexible pouch that is crushed by a propellant, mounts the pouch in the container body, and fixes the adapter to the mouth of the container body. An air passage is formed between the adapter and the mouth, and the propellant ejected from the aerosol can is supplied to the gap between the container body and the pouch via the air passage to press the pouch and press the mouth of the container body. The housing is fixed to the housing, the housing has a holder chamber that holds the nozzle and the aerosol can, and a valve that is adjacent to the holder chamber and that opens and closes the flow path of the housing to control the ejection of the contents. The upper part is characterized by an operating body for gradually pressing the valve head and the aerosol can bottom.

[0008]

[Action]

 The operation of the present invention having the above structure 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 portion to push down the valve and open 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. h can be adjusted depending on the initial ejection condition of the contents). In this state, even if the valve is open, the propellant does not squirt out of the aerosol can, so the contents do not flow out from the pouch. Next, when the pushing of the operating body is advanced and the operating body is further lowered, as shown in FIG. 3, the aerosol can pressing portion comes into contact with 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 passage and filled between the container body and the pouch. Since the pouch is gradually pressed as the propellant increases, the contents inside the pouch gradually flow out to the outside from the flow passage and the nozzle formed in the housing. That is, the force of the contents to flow out gradually increases as the amount of the propellant filling the outer periphery of the pouch increases.

When the pressing of the operating body is stopped, the aerosol can pressing portion and the aerosol can bottom part first come out of contact with time, and the propellant stops flowing out. At this time, the housing opening is still open, but the content in the pouch gradually decreases as the propellant decreases, and eventually the outflow stops. That is, in the beverage container according to the present invention, only the amount of the propellant supplied from the aerosol can is applied to the pouch by the pressing force, and the contents flow out. Therefore, unlike the conventional drinking container shown in FIG. 4, the pressing force of the propellant does not always act on the pouch. The valve element installed in the valve chamber provided at the tip of the stem of the aerosol can drops due to the jetting force of the propellant from the aerosol can, and the propellant is supplied to the ventilation passage through the valve chamber, Filled between the body and the pouch.

【Example】

 Next, the 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 portion 3 of the flexible pouch 2, the pouch body 2 is mounted in the container body 1, and the collar portion 8 of the adapter 5 is packed 23. It is sandwiched and fixed between the mouth portion 6 of the container body 1 and the housing 7 via. A ventilation passage 4 is formed between the adapter 5 and the mouth 6 of the container body 1, and the ventilation passage 4 communicates between the container body 1 and the pouch 2. Furthermore, this ventilation path 4 communicates with the stem 24 of the aerosol can 12 via the valve chamber 9 of the housing 7. The valve body 10 mounted in the valve chamber 9 is easily opened by the propellant jetting force. The flow of the propellant in the opposite direction is blocked by this valve body 10. The valve body 10 may be a valve body of any structure as long as it is opened by the propellant jetting force, and may be a normally 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 that is substantially inscribed in the container body 1. The film is usually a multilayer film, for example, a polyethylene film laminated on both sides of an aluminum foil or an EVOH (saponified ethylene vinyl alcohol copolymer) film is used depending on the type of beverage to be stored.

The housing 7 is formed in a cap shape, and a nozzle 22 protruding in a radial direction is attached to a side surface of the housing 7. On the opposite side of the nozzle 22, a holder chamber 11 for engaging and mounting a small aerosol can 12 is formed, and in the embodiment, the aerosol can 12 is installed upside down. Further, a valve chamber 25 is provided adjacent to the holder chamber 11, and a valve 18 for controlling ejection of contents is vertically provided in the valve chamber 25 so as to block the flow path 26, and a spring 20 is provided. Being energized. The valve seat 19 with a packing attached to the lower end of the valve 18 is closely contacted with or separated from the housing opening 21 so that the housing opening 21 is opened and closed to allow the contents to flow out or to flow in. Can be stopped. A female screw is formed in the lower part of the housing 7 and is screwed into the mouth 6 of the container body 1.

Further, the feature of the present invention resides 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 is in contact with the valve head 17, there is a gap of h 2 between the aerosol can pressing portion 15 and the aerosol can bottom portion 14. Then, even if the operating body 13 is pressed, the propellant does not flow out from the air can 12 immediately. In other words, 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 portion 14 by the pressing operation is different over time. Has become.

In the embodiment, the aerosol can 12 is filled with a liquefied gas (for example, chlorofluorocarbon). 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. Further, compared with the conventional case where a compressed gas (for example, carbon dioxide gas) is used, a pressure regulating valve is not required and the structure of the entire device is simple, so that it can be manufactured at low cost. Furthermore, by setting the volume of 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 content of beer or the like suddenly flows out at the moment when the valve is opened as in the conventional case, There is no risk of soiling clothes. Moreover, the structure is simple and the number of parts is small, so that it can be manufactured at low cost.
