The inverted beverage container 2 is suspended from the mounting portion 31. To ensure that the piercing is performed, it is preferable that the tip of the discharge pipe 34 be formed sharp as shown in FIG.
[0033]
Since the laminated film 11A constituting the pouring port portion 11 is a laminated film obtained by laminating a stretched nylon film and a polyolefin-based resin film as described above, when the pouring conduit 34 is pierced, The hole (penetration) in the piercing portion of the laminated film 11A is tightly attached to the pouring conduit 34 without tearing, and the airtightness and liquid tightness can be maintained even in a pressurized state.
[0034]
The airtightness and liquid tightness of the beverage container 2 and the server 3 in the pressurized state are ensured only at the close contact portion at the penetrating portion between the pipe 34 for pouring and the laminate film 11A. Therefore, a mechanism having a complicated structure with a large number of parts as in the related art is not necessary to ensure airtightness and liquid tightness in a pressurized state at the connection part. You can easily solve your problems.
[0035]
In particular, in the present invention, since the beverage container 2 can be connected to the server 3 by piercing the extraction conduit 34 into the laminated film 11A without opening the beverage container 2, the foamed beverage inside is completely exposed to air. , And can be kept in a state where the flavor from the factory is maintained.
[0036]

However, the spout 21 provided with the lid 1 is not a spout for a sparkling beverage, but a spout is provided in the main body of the beverage container 2. In this case, the spout structure in which the laminated film 11A is disposed at an arbitrary position of the main body of the beverage container 2 is provided.
[0040]
Further, in the case where the beverage container 2 is not a two-member structure of the container body and the lid 1, but is a sealed container without the lid 1 to be opened, the beverage container 2 having the laminated film 11A as the lid may be used. .
[0041]
Further, in the above embodiment, the laminated film 11A is pressed and fixed by the film fixing member 12, but the laminated film 11A may be directly fixed to the lid 1 by means of adhesion, fusion, welding or the like. . In this case, the membrane fixing member 12 is not required, but may be added for improving the airtightness and liquid tightness with the upper end of the mouth 20 of the beverage container 2. Even if the laminated film 11A is fixed to the lid 1 or pressed and fixed by the membrane fixing member 12, a new one can be obtained simply by replacing only the laminated film 11A with an unperforated new one. It can be reused as the beverage container 2 (of course, washing and sterilization of the beverage container 2 is necessary).
[0042]
Further, as the film capable of maintaining the liquid tightness and the air tightness, the laminate film 11A formed by laminating an unstretched nylon film and a polyolefin resin film has been described. Other materials, such as natural rubber, synthetic rubber, and synthetic resin, may be used as long as they can maintain airtightness.
[0043]
