(First embodiment)
As a first embodiment, a beverage container before filling with a beverage will be described. FIG. 1 is a schematic cross-sectional view of a beverage container 1 in the first embodiment.

  The beverage container 1 includes an outer container 10, an inner bag 20, a cap member 30, a first seal member 40, and a lid member 50. The outer container 10 is a container having rigidity capable of maintaining its shape, and is, for example, a resin container such as a plastic bottle or a metal container such as a stainless steel container. For example, the shape of the outer container 10 does not substantially change even when the pressure inside the container is increased to about 1.3 atm. The outer container 10 includes a first opening 12. In the example illustrated in FIG. 1, the first opening 12 is the neck of the outer container 10, and an outer peripheral screw portion 14 is formed on the lateral outer surface of the first opening 12.

  The outer container 10 has a shoulder 16. The shape of the shoulder portion 16 includes a shape corresponding to the side surface of the cone (a shape complementary to the side surface of the cone). For this reason, the line of intersection between the shoulder 16 and an arbitrary plane passing through the longitudinal center axis C of the outer container 10 includes a straight portion.

  The shoulder 16 of the outer container 10 may be provided with a plurality of reinforcing ribs (not shown) that suppress deformation of the shoulder 16. Similarly, the body portion 18 of the outer container 10 may be provided with a plurality of reinforcing ribs (not shown) that suppress deformation of the body portion 18. The reinforcing rib of the shoulder portion 16 is provided, for example, along a line of intersection between the shoulder portion 16 and a predetermined plane passing through the longitudinal central axis of the outer container. Further, the reinforcing ribs of the body portion 18 are provided along a direction parallel to the longitudinal central axis C, for example.

  The inner bag 20 is a bag-like container whose shape changes as the beverage is filled. The inner bag 20 is made of, for example, a sheet of nylon or the like coated with aluminum foil or the like. The inner bag 20 can be formed by superimposing two sheets (nylon sheet or the like) and welding the peripheral portions of the two sheets by high-frequency welding.

  FIG. 2A is a schematic plan view of the inner bag 20. The peripheral edges 24 of the two sheets are welded together. The inner bag 20 includes a second opening 22. In the second opening 22, one or a plurality of reinforcing sheets 26 may be laminated by welding or the like on the outer side of each of the two sheets (nylon sheets or the like) superimposed. The reinforcing sheet 26 disposed on one side of the two sheets and the reinforcing sheet 26 disposed on the other side of the two sheets are welded together. The strength of the second opening 22 is improved by the reinforcing sheet 26.

  The inner bag 20 includes a shoulder portion 27 and a trunk portion 28. In the example shown in FIG. 2A, the angle formed by the peripheral edge 24 of the shoulder 27 and the peripheral edge 24 of the body 28 is an obtuse angle greater than 90 °.

  2B is a cross-sectional view taken along the line AA in FIG. The inner bag 20 is arrange | positioned in the outer container 10 before drink filling. 2B, in order to facilitate the insertion of the inner bag 20 into the outer container 10 or to facilitate the expansion of the inner bag 20 during beverage filling, the inner bag 20 You may insert in the outer container 10 in the state wound by the spiral shape. In addition, the method of winding the inner bag 20 is not limited to the example illustrated in FIG. 2B and is arbitrary.

  As shown in FIG. 1, the inner bag 20 is bent in the longitudinal center axis C in a state of being arranged in the outer container 10, that is, a curved shape (see the waveform shape in FIG. 1). ). The length of the inner bag 20 in the non-filled state of the beverage (for example, the length from the upper surface of the plug member to the lower end of the inner bag 20 with respect to the inner bag 20 with the plug member 30 attached) is the outer container. It is longer than the length of 10 (the length in the direction along the central axis C in the longitudinal direction). As a result, in a state where the inner bag 20 is filled with a beverage, in other words, in a state where the length of the inner bag 20 is shortened by the expansion of the inner bag 20, the outer surface of the bottom of the inner bag 20 and the outer container 10 It is possible to reduce the gap between the inner surface of the bottom portion.

  When the inner bag 20 is filled with a beverage, in other words, when the inner bag 20 is in an expanded state, the shoulder portion 27 of the inner bag 20 includes a shape complementary to the side surface of the cone. Since the shape of the shoulder 27 when the inner bag is inflated and the shape of the shoulder 16 of the outer container 10 are complementary to each other, a gap between the inner surface of the outer container 10 and the outer surface of the inner bag 20 Can be reduced.

  The inner surface shape of the outer container 10 and the outer surface shape of the inner bag 20 at the time of maximum expansion are not limited to the above-described example, but are arbitrary. However, in order to reduce the gap between the inner surface of the outer container 10 and the outer surface of the inner bag 20, the inner surface shape of the outer container 10 (excluding the first opening 12) and the inner bag 20 at the time of maximum expansion are used. It is preferable that the outer shape (excluding the second opening 22) of each other is the same shape. In the present specification, the same shape includes substantially the same shape.

  In addition, air between the bottom of the outer container 10 and the bottom of the inner bag passes between the inner side surface of the outer container 10 and the outer side surface of the inner bag 20 so as to be easily discharged from a vent 32 described later. A plurality of protrusions or a plurality of protrusions may be formed on the inner surface of the bottom of the outer container 10 or the inner surface of the body.

  As shown in FIG. 1, the plug member 30 is attached to the second opening 22 of the inner bag 20 and is attached to the first opening 12 of the outer container 10. The bonding between the plug member 30 and the second opening 22 may be welding between the lower outer peripheral surface 31 of the plug member 30 and the inner peripheral surface 23 of the second opening 22. Further, the bonding between the outer container 10 and the first opening 12 may be welding between the upper outer peripheral surface 37 of the plug member 30 and the inner peripheral surface 33 of the first opening 12. In the example illustrated in FIG. 1, the plug member 30 includes an upper flange portion 36 </ b> A and a lower cylinder portion 36 </ b> B. The outer peripheral surface of the upper flange portion 36 </ b> A is the upper outer peripheral surface 37, and the outer peripheral surface of the lower cylindrical portion 36 </ b> B is the lower outer peripheral surface 31.

  The plug member 30 includes a vent hole 32 and a beverage passage hole 34. The vent hole 32 communicates with an opening provided on the upper surface of the plug member 30. The vent hole 32 communicates with an opening provided on the lower surface of the plug member 30 (more specifically, an opening provided on the lower surface of the upper flange portion 36A). The lower end of the vent hole 32 faces the space between the first opening 12 and the second opening 22 and communicates with the space 60 between the outer container 10 and the inner bag 20. As will be described later, the cap member 30 is provided with a vent hole 32 so that the inner bag 20 is filled with a beverage in a state where the pressure of the space 60 between the outer container 10 and the inner bag 20 is adjusted. Is possible. Further, as will be described later, it is possible to pour a beverage from the inner bag 20 by injecting a gas such as air into the space 60 through the vent hole 32 of the plug member 30.

  The beverage passage hole 34 is a hole used for filling beverage into the inner bag 20 and for pouring the beverage from the inner bag 20. In other words, the beverage passage hole 34 is a beverage filling hole / beverage pouring hole and is a hole that can communicate with the internal space of the inner bag 20. The beverage passage hole 34 may be provided with a tearable sealing film 38 that seals the beverage passage hole 34. In the case where the sealing film 38 is attached, it is possible to prevent foreign matter from entering the inner bag 20 until just before the beverage is filled into the inner bag 20. In addition, at the time of beverage filling, the sealing film 38 is broken, and the spaces separated from each other by the sealing film 38 communicate with each other. The position where the sealing film 38 is disposed may be the upper end of the beverage passage hole 34, the lower end of the beverage passage hole 34, or the middle portion of the beverage passage hole 34. Good.

  3 is a BB arrow view of the plug member 30 as viewed along the direction of the arrow BB in FIG. In the example illustrated in FIG. 3, the beverage passage hole 34 is a hole provided in the central portion of the plug member 30, and is a hole concentric with the central axis C in the longitudinal direction of the plug member 30. In the example shown in FIGS. 1 and 3, the longitudinal center axis C of the plug member 30 coincides with the longitudinal center axis C of the outer container 10. An annular groove 35 centering on the central axis C is provided on the upper surface of the plug member 30. The annular groove 35 communicates with the vent hole 32. More specifically, an opening provided at the bottom of the annular groove 35 communicates with the vent hole 32. A portion of the upper surface of the plug member 30 located between the annular groove 35 and the beverage passage hole 34 constitutes an annular seal surface 39 that contacts the first seal member 40. The contact between the first sealing member 40 and the annular sealing surface 39 prevents communication between the vent hole 32 and the beverage passage hole 34. In the example shown in FIG. 3, the number of the vent holes 32 is one, but the number of the vent holes 32 may be two or more.

  As shown in FIG. 1, the first seal member 40 is a member disposed in contact with the upper surface of the plug member 30 and can prevent communication between the vent hole 32 and the beverage passage hole 34. It is an important member. In the example illustrated in FIG. 1, the first seal member 40 is a member that can seal or close the vent hole 32 and the beverage passage hole 34 at the same time, and has a disk shape. The first seal member 40 may be integrated with the lid member 50 by bonding or the like. The first seal member 40 is a member having elasticity.

  The lid member 50 is a member that is attached to the first opening 12 of the outer container 10. In the example illustrated in FIG. 1, the lid member 50 is a bottomed cylindrical cap including a top plate portion 51 and a skirt portion 52. The skirt portion 52 is formed with an inner peripheral screw portion 54. The inner peripheral screw portion 54 is screwed into the outer peripheral screw portion 14 of the first opening 12 of the outer container 10, whereby the lid member 50 is attached to the first opening 12. When the lid member 50 is attached to the first opening 12 (in other words, when the lid member 50 is screwed into the first opening 12), the top plate portion 51 of the lid member 50 causes the first seal member 40 to move. Press against the upper surface of the plug member 30. As a result, communication between the vent hole 32 and the beverage passage hole 34 is prevented. Even if the sealing film 38 is not provided by preventing the communication between the vent hole 32 and the beverage passage hole 34, or even after the sealing film 38 is broken. The air is prevented from entering the inner space of the inner bag 20 from the outside of the beverage container 1.

In the example illustrated in FIG. 4, the filling joint 70 includes a skirt portion, a top plate portion, a beverage supply path 76 (beverage supply pipe), and a vent path 74 (vent pipe).

  The skirt portion of the filling joint 70 is provided with an inner peripheral screw portion 73 that is screwed into the outer peripheral screw portion 14 of the first opening 12. The filling joint 70 is attached to the first opening 12 by screwing the outer peripheral screw portion 14 and the inner peripheral screw portion 73. By attaching the filling joint 70 to the first opening 12, communication between the vent hole 32 and the vent path 74 and communication between the beverage passage hole 34 and the beverage supply path 76 are realized at the same time. .

  The filling joint 70 includes a beverage supply path 76. In the example shown in FIG. 4, a hollow needle is provided at the lower end of the beverage supply path 76. The filling needle 70 is attached to the first opening 12 so that the hollow needle breaks the sealing film 38. The other end side of the beverage supply path 76 is connected to a beverage supply device (not shown) via a filling pipe 78 and the like.

  The filling joint 70 includes an air passage 74. A pressure regulating valve 72 is disposed in the ventilation path 74. The pressure regulating valve 72 opens the air passage 74 when the pressure in the portion of the air passage 74 on the side communicating with the air vent 32 becomes equal to or higher than a predetermined set pressure higher than the atmospheric pressure, and a pressure lower than the predetermined set pressure. Then, the air passage 74 is configured to be closed. The set pressure can be adjusted by an adjusting mechanism such as a set pressure adjusting screw 75. The set pressure is set to, for example, a predetermined pressure within a range of 1.1 to 3 atmospheres, 1.1 to 2 atmospheres, or 1.2 to 1.5 atmospheres. The lower end of the air passage 74 communicates with an annular groove 77 provided on the lower surface of the top plate portion of the filling joint 70. The annular groove 77 is provided at a position overlapping the annular groove 35 when viewed in the direction along the central axis C.

  The filling joint 70 may be provided with a gas supply path 71 and a closing member 79 that can open and close the gas supply path 71. The closing member 79 may be a lid or a valve.

  A second seal member 80 is disposed between the lower surface of the top plate portion of the filling joint 70 and the upper surface of the plug member 30. The second seal member 80 is a member disposed in contact with the upper surface of the cap member 30 and is a member capable of preventing communication between the vent hole 32 and the beverage passage hole 34. The second seal member 80 may be integrated with the filling joint 70 by bonding or the like. The second seal member 80 is a member having elasticity.

  FIG. 5 is a schematic plan view of the second seal member 80. The second seal member 80 is a ring-shaped member. The second seal member 80 is provided with a first through hole 82 that communicates with the beverage passage hole 34 when disposed between the filling joint 70 and the plug member 30. In addition, the second seal member 80 is provided with a second through hole 84 that communicates with both the annular groove 77 and the annular groove 35 when disposed between the filling joint 70 and the plug member 30. Yes. The region on the inner peripheral side of the second seal member 80 with respect to the second through hole 84 is an annular seal region 85 that contacts the annular seal surface 39 of the plug member 30 (see the hatched portion). The contact between the sealing region 85 and the annular sealing surface 39 prevents communication between the vent hole 32 and the beverage passage hole 34. In the example illustrated in FIG. 5, the number of the second through holes 84 is one, but the number of the second through holes 84 may be two or more.

  Next, with reference to FIG. 4 and FIG. 6, the filling method of the drink to the drink container 1 is demonstrated. In the first step S <b> 1, the lid member 50 is removed from the first opening 12 of the outer container 10. At this time, the first seal member 40 may be removed together with the lid member 50.

  In the second step S <b> 2, an air passage 74 in which a pressure regulating valve 72 is disposed is connected to the vent hole 32 of the plug member 30 so as to be in fluid communication, and a beverage is supplied to the beverage passage hole 34 of the plug member 30. A passage 76 is connected to be in fluid communication. In the example shown in FIG. 4, by attaching the filling joint 70 to the first opening 12, communication between the vent hole 32 and the vent path 74, and between the beverage passage hole 34 and the beverage supply path 76. Communication is realized at the same time. In the second step S <b> 2, the sealing film 38 may be broken by the beverage supply path 76 by inserting the beverage supply path 76 into the beverage passage hole 34.

  In the third step S3, the set pressure (open pressure) of the pressure regulating valve 72 is adjusted. Note that the third step can be omitted when the opening pressure of the pressure regulating valve 72 is set in advance.

  In the fourth step S <b> 4, the beverage is supplied from the beverage supply device, and the inner bag 20 is filled with the beverage through the beverage supply path 76 and the beverage passage hole 34. As the inner bag 20 is filled with a beverage, the inner bag 20 expands. The volume of the space 60 between the outer container 10 and the inner bag 20 decreases due to the expansion of the inner bag 20. Due to the volume reduction of the space 60, the atmospheric pressure in the space 60 increases until reaching the set pressure of the pressure regulating valve 72, and then the atmospheric pressure in the space 60 is maintained at the set pressure. Since beverage filling into the inner bag 20 is performed with the set pressure acting on the outer surface of the inner bag 20, bubbles (for example, carbon dioxide when the beverage is a carbonated beverage) may be generated from the beverage. It is suppressed. As a result, the beverage state is suppressed from changing during beverage filling. The filling joint 70, the second seal member 80, the filling pipe 78, and the beverage supply device that supplies the beverage to the filling pipe 78 constitute a beverage filling apparatus.

  When the gas supply path 71 is provided in the filling joint 70, immediately before the fourth step S4, the air is introduced into the space 60 via the gas supply path 71, the vent path 74, and the vent hole 32. A gas such as carbon dioxide may be supplied. By supplying the gas to the space 60, it is possible to make the air pressure in the space 60 higher than the atmospheric pressure before the beverage is supplied to the inner bag 20. By increasing the atmospheric pressure in the space 60 in advance, it is further suppressed that bubbles are generated from the beverage when filling the beverage.
