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, the present invention is a beverage container in which propellant ejected from an aerosol can is supplied to a pouch in a container body via an air passage and the contents are ejected by expanding the pouch, A housing is attached to the mouth of the container body, and the housing has a holder chamber for holding the nozzle and the aerosol can, and is adjacent to the holder chamber and has a valve for opening and closing the flow path of the housing to control the outflow of contents. In addition, an operating body that presses the valve head and the aerosol can bottom together in a stepwise manner is provided on the upper part of the housing.

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 contacts the valve head 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. The gap H can be adjusted depending on the initial outflow 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 inside of the container body. Further, when the pushing of the operating body is advanced and the operating body is lowered, as shown in FIG. 3, the aerosol can pressing portion contacts the bottom of the aerosol can and opens the valve of the aerosol can. At this time, the propellant is first filled into the container body and the pouch from the aerosol can. Then, the pouch gradually expands as the propellant increases, and the expansion pressure pushes away and presses the contents, which then flows out of the container body.

Next, when the pressing of the operating body is stopped, the aerosol can pressing part and the aerosol can bottom part first come out of contact with time, the propellant stops flowing out, and thereafter the volume of the pouch 2 increases. Nor does it decrease. At this time, the housing opening is open, but after a certain amount of the contents has flowed out, the pressure decreases, so the momentum of the outflow gradually decreases, and eventually the outflow stops. .. That is, in the beverage container according to the present invention, the pouch expands by the amount of the propellant supplied from the aerosol can, and the contents are pushed away by the expanded amount and flow out to the outside. Therefore, unlike the conventional beverage container shown in FIG. 4, the pressing force of the propellant does not always act on the pouch. As shown in Fig. 3, the valve element installed in the valve chamber provided at the tip of the stem of the aerosol can drops due to the jet pressure of propellant from the aerosol can, and the propellant passes through the valve chamber and vents. It is supplied to the road and filled in the pouch.

【Example】

 Next, the invention will be described with reference to the drawings. In the beverage container according to the present invention, a mouth portion 3 of a flexible pouch 2 is welded to an opening 5a of an adapter 5 hanging from a housing 4, and the pouch 2 is suspended in a container body 1. A vent passage 6 is formed in the adapter 5, and the vent passage 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 propellant jet pressure from the aerosol can 9. Further, the valve element 8 blocks the flow of the propellant in the opposite direction. As shown in FIG. 3, the valve body 8 may have any structure as long as it has a function of releasing the outlet of the stem 9a by the ejection pressure of the propellant from the aerosol can 9. Alternatively, a plate valve or the like which is normally used may be used.

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

The housing 4 is formed in a cap shape, and a nozzle 15 protruding in the radial direction is attached to the side surface of the housing 4. On the opposite side of the nozzle 15, a holder chamber 19 for mounting and fixing a small aerosol can 9 is formed, and in the embodiment, the aerosol can 9 is installed upside down. Further, a valve chamber 12 is provided adjacent to the holder chamber 19, and a valve 16 for controlling ejection of the contents is vertically provided in the valve chamber 12 so as to block the flow passage 14, and a spring 13 is provided. Being energized. When the valve seat 18 with a packing attached to the lower end of the valve 16 is brought into close contact with or separated from the housing opening 17, the housing opening 17 is opened and closed to allow the contents to flow out or to flow out. Can be blocked.

Further, the feature of the present invention resides in the structure of the operating body 20 provided on the upper portion of the housing 4 so as to be vertically movable. That is, when the valve pressing portion 11 contacts the valve head 16a, a gap H is provided between the aerosol can pressing portion 10 and the aerosol can bottom portion 9b as shown in FIG. Then, even if the operating body 20 is pressed, the propellant does not immediately jet from the aerosol can 9. That is, the valve pressing part 11 and the aerosol can pressing part 10 formed on the operating body 20 have such a structure that the contact with the valve head 16a or the aerosol can bottom part 9b due to the pressing operation is different with time. ing.

Further, in the embodiment, the aerosol can 9 is filled with liquefied gas (for example, CFC gas). By using such a liquefied gas, the pressing force to the contents in the container body 1 becomes constant and the ejection pressure of the contents becomes stable. Further, compared with the conventional case where a compressed gas (for example, carbon dioxide gas) is used, a pressure adjusting valve is not required and the structure of the entire apparatus is simple, so that it can be manufactured at low cost. Furthermore, by setting the volume of liquefied gas to be 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 etc. Also, the structure is simple and the number of parts is small, so it has the effect of being inexpensive to manufacture.
