DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a beverage container according to the present invention will be described below with reference to the drawings. 1 and 2 show the first invention.
In the container according to this embodiment , a cylindrical adapter 3 is attached to a mouth 2 of a flexible pouch 1 by welding or bonding, and a ball valve 7 is attached to the adapter 3. set,
The pouch 1 is mounted in the container body 4, the adapter 3 is fitted into the mouth 5 of the container body 4, and the outer diameter of the adapter 3 is smaller than the inner diameter of the mouth 3, and Between the container body 4 and the pouch 1 from outside the container body 4.
And a ventilation path 6 leading to the space.

The pouch 1 is made of a film having great flexibility and a high gas barrier property, and is formed in a shape almost inscribed in the container body 4. The film is usually a multi-layer film, depending on the type of beverage to be stored, for example, a polyethylene film laminated on both sides of an aluminum foil or an EVO inside.
A laminate of H (saponified ethylene-vinyl acetate copolymer) films is used. The container body 4 is made of aluminum, glass, or synthetic resin similarly to a conventional large-capacity wine bottle, and a small-diameter mouth portion 5 is formed above a body portion 4a through a shoulder portion 4b whose diameter gradually narrows. Is provided.
A female screw cap 9 having a packing 9a is screwed into the mouth 5 of the container body 4 so that the mouth 5 can be sealed.

The adapter 3 comprises an upper cylindrical body 3a, a tapered portion 3b narrowing in a tapered shape, and a small-diameter lower cylindrical body 3c. The tapered portion 3b is provided with a ball valve 7 for closing the tapered portion 3b, and the diameter of the ball valve 7 is formed larger than the diameter of the lower cylinder 3c. Therefore, when the ball valve 7 is below, that is, when the ball valve 7 is in contact with the tapered portion 3b, the tapered portion 3b
Is closed, and when the ball valve 7 is at the top, the tapered portion 3b
Is open. Further, in order to prevent the ball valve 7 from going out of the upper cylinder 3a, a ball stopper adapter 8 is fitted into the upper cylinder 3a. Since the notch 8a is formed at several locations below the ball stopper adapter 8, the contents can be discharged from the notch 8a.

Next, FIG. 3 is a sectional view showing the second invention. The feature of this invention is that an elliptical valve 1 is used instead of the ball valve 7.
7 is provided in the adapter 3, and the ball stopper 18 is formed integrally with the adapter 3 on the upper cylindrical body 3 a of the adapter 3. This ball stop 18
Are formed with several notches 18a, and similarly, the contents flow out from the notches 18a.

FIG. 4 shows a third invention. The feature of this invention is that an engaging projection 9c is formed on the inner top surface of the cap 9, and the inner peripheral surface of the inner plug 11 is formed on the engaging projection 9c. This is the point where the engagement is easily performed . The ball valve 7 is inserted into the inside plug 11. A projection 11 a is formed on the outer periphery of the inner plug 11. When the cap 9 is screwed into the mouth 5, the projection 11 a is attached to the adapter 3.
Is strongly fitted to the recess 3e. Once fitted, inner plug 1
1 and the adapter 3 are firmly fitted to each other, so that they are not detached again. This allows the cap 9 to be screwed into the mouth 5 and the inner plug 11 to be assembled to the mouth 5 at the same time, which simplifies the manufacturing process. FIG. 4
In the upper part of the adapter 3, the same detent portion as in FIG.
12 are provided.

Next, an example of a method for manufacturing a container and a method for filling a beverage according to the present invention will be described. First, the container body 4 is manufactured by a method such as impact molding or blow molding. Further, the mouth portion 2 of the pouch 1 is bonded or fused to the lower cylinder 3c of the adapter 3. Then, the pouches 1 are grouped into small pieces, inserted into the container body 4 from the mouth 5 of the container body 4, and the adapter 3 is fitted into the mouth 5. A notch 3d is formed at the upper end of the adapter 3, and air is supplied between the container body 4 and the pouch 1 from the notch 3d. Then, a predetermined amount of a beverage 10 such as wine is injected into the pouch 1 through the adapter 3. At this time, with the injection of the beverage 10,
The pouch 1 spreads to a state almost inscribed in the container body 4,
The air between the pouch 1 and the container body 4 is discharged outside through the ventilation path 6. Thereafter, the ball valve 7 is fitted into the adapter 3, and the cap 9 is screwed into the mouth 5 to seal it.

When wine, juice, or the like flows out of the beverage container according to the present invention, the cap 9 is removed, the container body 4 and the mouth 5 are held by hand, and the container body 4 is tilted and the beverage is put into a cup or the like. When the pour 10 is poured, the beverage 10 in the pouch 1 pushes and opens the ball valve 7, flows into the adapter 3, and flows out from the notches 8a and 18a. On this occasion,
Air corresponding to the outflow amount of the beverage 10 passes through the ventilation path 6,
Since it flows between the container body 4 and the pouch 1, the pouch 1
The beverage 10 flows out smoothly while shrinking, and no new air flows into the pouch 1 due to the presence of the ball valve 7 and the elliptical valve 17.

[0014]

As described above, according to the present invention, there is no fear that the beverage remaining in the pouch is oxidized or deteriorated by the inflow of new air. Therefore, even if a drink is left after the beverage container is opened, if the mouth is sealed, the remaining beverage can be held in the same state as before the opening.
