[0027] As illustrated in FIG. 1, the beverage container 1 comprises an outer container 2, a lid member 3, and a replacement part 5 including a pouch 58.

[0028] The outer container 2 defines an internal space SP1 in which the replacement part 5 including the bag 58 is placed. The outer container 2 has a container body 22 and a first mouth 27. In the example shown in FIG. 1 , the first mouth 27 extends upward from the container body 22. The outer container 2 is made of, for example, metal (more specifically, stainless steel). Alternatively, the outer container 2 may be made of resin.

[0029] The lid member 3 is attached to the first opening 27 of the outer container 2. In the example shown in Fig. 1, the first opening 27 has a first screw portion 27s (more specifically, a male screw portion). The first opening 27 defines a first opening OP1 through which the replacement part 5 can pass.

[0030] The cover member 3 includes an attachment portion 31 , an upper pipe portion 34 , an annular portion 40 , and a lower pipe portion 37 .

[0031] The attachment portion 31 is attached to the first opening 27 of the outer container 2. In the example shown in FIG. 1, the attachment portion 31 has a second screw portion 31s (more specifically, a female screw portion) that screws into the first screw portion 27s of the first opening 27. The attachment portion 31 is made of, for example, metal (more specifically, stainless steel). Alternatively, the attachment portion 31 may be made of resin.

[0032] As illustrated in Fig. 2, the upper pipe portion 34 is disposed outside the outer container 2. A beverage dispenser 110 or a first closure member 70 (see, for example, Fig. 16) can be attached to the upper pipe portion 34. In the example illustrated in Fig. 2, the upper pipe portion 34 extends upward from the annular portion 40. The upper pipe portion 34 is made of, for example, metal (more specifically, stainless steel). Alternatively, the upper pipe portion 34 may be made of resin.

[0033] The annular portion 40 protrudes outward from the upper pipe portion 34 (in other words, the annular portion 40 protrudes from the upper pipe portion 34 in a direction away from the central axis C1 of the upper pipe portion 34). The annular portion 40 also connects the upper pipe portion 34 and the mounting portion 31. In the example shown in FIG. 1 , the annular portion 40 has an inner portion 401 connected to the upper pipe portion 34 and an outer portion 402 connected to the mounting portion 31.

[0034] Since the cover member 3 has the annular portion 40, the inner diameter of the first opening 27 of the outer container 2 can be made significantly larger than the inner diameter of the upper tube portion 34. When the inner diameter of the first opening 27 is large, it is easy to insert the replacement part 5 having the bag body 58 into the inside of the outer container 2 through the first opening 27.

[0035] 2, the lower pipe portion 37 is disposed lower than the upper pipe portion 34. The inner surface of the lower pipe portion 37 and the inner surface of the upper pipe portion 34 define a beverage flow path F1.

[0036] The lower tube portion 37 extends downward from the annular portion 40. In the example shown in FIG. 2, the lower tube portion 37 protrudes from the annular portion 40 in a direction toward the bottom 23 of the outer container 2. The replacement part 5 is attached to the lower tube portion 37. The lower tube portion 37 is made of, for example, metal (more specifically, stainless steel). Alternatively, the lower tube portion 37 may be made of resin.

[0037] The replacement part 5 is attached to the lower pipe portion 37 and is disposed in the internal space SP1 of the outer container 2. In the example shown in FIG. 2, the entire replacement part 5 is disposed in the internal space SP1 of the outer container 2.

[0038] As illustrated in Fig. 3, the replacement part 5 includes a sealing member 52, a cylindrical body 55, and a bag body 58. The replacement frequency of the replacement part 5 is higher than the replacement frequency of the outer container 2 and the lid member 3. Repeated reuse of the outer container 2 and the lid member 3 reduces the burden on the environment. When one cycle is defined as the period from when the beverage container 1 is filled with a beverage to when the beverage container 1 is next filled with a beverage, the replacement part 5 may be replaced every cycle. In other words, the replacement part 5 may be a disposable part that is used only once.

[0039] The seal member 52 is slidable relative to the lower pipe portion 37. More specifically, the seal member 52 is slidable relative to the lower pipe portion 37 in a direction parallel to the central axis C2 of the lower pipe portion 37. In this case, it is easy to move the seal member 52 toward the attachment position P in the lower pipe portion 37, and it is easy to position the seal member 52 at the attachment position P in the lower pipe portion 37.

[0040] In the final stage when the seal member 52 reaches the mounting position P, the seal member 52 slides relative to the lower pipe portion 37 with the outer surface 37u of the lower pipe portion 37 in annular contact with the seal member 52. In other words, in the final stage when the seal member 52 reaches the mounting position P, a moderate frictional resistance is generated between the seal member 52 and the lower pipe portion 37. If the frictional resistance is too small, the seal member 52 may be determined to be a defective product.

[0041] 4, when the seal member 52 is located at the mounting position P, it comes into annular contact with the outer surface 37u of the lower pipe portion 37. This contact prevents fluid (in other words, beverage or gas) from leaking from between the seal member 52 and the lower pipe portion 37. The seal member 52 is made of an elastic material such as rubber.

[0042] The cylindrical body 55 is disposed outside the seal member 52 and holds the seal member 52. When the seal member 52 is located at the attachment position P in the lower tubular portion 37, the cylindrical body 55 prevents the outer diameter of the seal member 52 from increasing. In this way, the seal member 52 disposed between the cylindrical body 55 and the outer surface 37u of the lower tubular portion 37 is compressed, improving the sealing effect of the seal member 52.

[0043] 4, the cylindrical body 55 is supported by the lower pipe portion 37 via the sealing member 52 located at the attachment position P. In addition, a bag body 58 for containing a beverage is attached to the cylindrical body 55.

[0044] 4, when the sealing member 52 is located at the mounting position P, the cylindrical body 55 to which the bag body 58 is attached is supported by the lower pipe portion 37 via the sealing member 52. In other words, simply by moving the sealing member 52 to the mounting position P, the replacement part 5 including the bag body 58 is supported by the lower pipe portion 37. Therefore, the configuration for preventing the replacement part 5 from falling off from the lower pipe portion 37 is simple.

[0045] In the first embodiment, the replacement part 5 having the seal member 52 is attached to the lower pipe part 37 by sliding the seal member 52 toward the attachment position P in the lower pipe part 37. This makes it easy to attach the replacement part 5 to the lower pipe part 37 (see FIGS. 3 and 4).

[0046] Moreover, in the first embodiment, the cover member 3 has an annular portion 40. The presence of the annular portion 40 allows the inner diameter of the first opening 27 of the outer container 2 to be significantly larger than the inner diameter of the upper tube portion 34 of the cover member 3. When the inner diameter of the first opening 27 is large, it is easy to insert the replacement part 5 having the bag body 58 into the inside of the outer container 2 through the first opening 27 (see FIG. 1).

[0047] As described above, the first embodiment provides a beverage container 1 that is easy to assemble.

[0048] Next, optional additional configurations that can be employed in the first embodiment will be described with reference to FIGS.

[0049] (Outer container 2) In the example shown in Fig. 5, the outer container 2 is a rigid container (in other words, a container whose shape does not change substantially). The container body 22 of the outer container 2 has a bottom 23 and a body 24. The container body 22 may have a shoulder 25 that connects the body 24 and the first opening 27. In the example shown in Fig. 5, the shoulder 25 and the first opening 27 are connected via a weld 26.

[0050] In the example shown in FIG. 5, the outer container 2 is a bottle-shaped container. The aspect ratio of the outer container 2 (in other words, the value obtained by dividing the length L1 of the outer container 2 by the maximum width W1 of the outer container 2) is, for example, 1.5 or more, 1.8 or more, or 2.0 or more. Because the maximum width W1 of the outer container 2 is relatively small, the shape of the bag 58 placed inside the outer container 2 is elongated. In this case, it becomes easier to more completely contract the bag 58, and the amount of beverage that ultimately remains without being removed from the bag 58 can be reduced. However, the aspect ratio of the outer container 2 is not limited to the above example. In other words, the shape of the outer container 2 does not have to be elongated.

[0051] The length L1 of the outer container 2 is, for example, 10 cm or more, 15 cm or more, or 20 cm or more. The inner diameter D1 of the first opening 27 of the outer container 2 is set to a value that allows the replacement part 5 to easily pass through. The inner diameter D1 of the first opening 27 is, for example, 6 cm or more and 12 cm or less, or 7 cm or more and 10 cm or less. When the inner diameter D1 of the first opening 27 is large, it is easy to insert the replacement part 5 having the bag body 58 into the inside of the outer container 2 through the first opening 27. The inner diameter D1 of the first opening 27 may be 0.4 times or more, 0.5 times or more, or 0.6 times or more the maximum width W1 of the outer container 2. Furthermore, from the viewpoint of easily inserting the cylindrical body 55 and the bag body 58 (see FIG. 1, etc.) attached to the cylindrical body 55 into the inside of the outer container 2, it is preferable that the inner diameter D1 of the first opening 27 be sufficiently larger than the maximum outer diameter of the cylindrical body 55 (more specifically, the outer diameter of the first flange portion 553 described below). The difference between the inner diameter D1 of the first opening 27 and the maximum outer diameter of the cylindrical body 55 (more specifically, the outer diameter of the first flange portion 553 described below) is, for example, 15 mm or more, 20 mm or more, or 25 mm or more.

[0052] In the example shown in FIG. 1 , the first screw portion 27s of the first opening 27 is a male screw portion (i.e., an external screw portion), and the second screw portion 31s of the attachment portion 31 that screws onto the first screw portion 27s is a female screw portion (i.e., an internal screw portion). Because the first screw portion 27s is a male screw portion, the inner surface 27n of the first opening 27 can be a smooth surface. If the inner surface 27n of the first opening 27 is a smooth surface, when the replacement part 5 having the bag body 58 is inserted into the outer container 2 through the first opening 27, the bag body 58 is less likely to get caught on the inner surface 27n of the first opening 27. This facilitates assembly of the beverage container 1. Alternatively, the first screw portion 27s of the first opening 27 may be a female screw portion, and the second screw portion 31s of the attachment portion 31 of the lid member 3 may be a male screw portion.

[0053] (Spacer member 63) In the example shown in FIG. 6, the beverage container 1 includes a spacer member 63 disposed between the annular portion 40 and the cylindrical body 55. The spacer member 63 prevents the bag body 58 from excessively deforming toward the annular portion 40. In the example shown in FIG. 6, the spacer member 63 is not attached to the cylindrical body 55. In other words, the cylindrical body 55 is movable relative to the spacer member 63 (more specifically, the cylindrical body 55 is movable relative to the spacer member 63 in the direction along the central axis C2 of the lower pipe portion 37). In this case, the spacer member 63 and the replacement part 5 having the cylindrical body 55 can be handled separately. For example, the replacement frequency of the spacer member 63 can be lower than the replacement frequency of the replacement part 5.

[0054] The spacer member 63 is preferably a non-flexible member (in other words, a member whose substantial deformation is suppressed). The spacer member 63 may be made of resin or metal such as stainless steel.

[0055] In the example shown in FIG. 2, when the internal pressure of the bag body 58 increases, a portion of the bag body 58 enters the annular region AR1 inside the first mouth 27, causing the bag body 58 to over-deform upward. This over-deformation of the bag body 58 may result in breakage of the bag body 58. In response to this, the spacer member 63 occupies a portion of the annular region AR1 inside the first mouth 27, thereby preventing the bag body 58 from over-deforming toward the annular portion 40. In the example shown in FIG. 6, the spacer member 63 is an annular body disposed between the lower pipe portion 37 and the first mouth 27.

[0056] In the example shown in FIG. 7, the height of the lower end 63g of the spacer member 63 is approximately the same as the height of the lower end 27g of the first opening 27. In this case, excessive deformation of the bag body 58 is prevented at the boundary between the lower end 63g of the spacer member 63 and the lower end 27g of the first opening 27. In the example shown in FIG. 7, the spacer member 63 has an upper end 63e that is located higher than the lower end 27g of the first opening 27. The upper end 63e is located in the annular region AR1 between the first opening 27 and the lower tube portion 37. The upper end 63e of the spacer member 63 may be able to come into contact with the annular portion 40 of the cover member 3.

[0057] 7, the spacer member 63 has an inner edge portion 63n that extends inward toward the lower pipe portion 37. The inner edge portion 63n of the spacer member 63 may function as a stopper that defines the upper limit position of the first flange portion 553 of the tubular body 55 of the replacement part 5.

[0058] In the example shown in Fig. 7, the spacer member 63 has a lower surface 63d disposed opposite the bag body 58. The lower surface 63d is preferably an inclined surface (more specifically, an inclined concave surface) whose height decreases with increasing distance from the central axis C2 of the lower pipe portion 37. In this case, when the internal pressure of the bag body 58 increases, the bag body 58 deforms gently along the lower surface 63d of the spacer member 63. As a result, excessive deformation of the bag body 58 is prevented, and damage to the bag body 58 is more effectively prevented.

[0059] 7, the spacer member 63 has a through-hole portion 63h into which the lower pipe portion 37 is inserted. The through-hole portion 63h may be capable of receiving the upper end portion 55e of the cylindrical body 55 of the replacement part 5. The inner diameter of the through-hole portion 63h of the spacer member 63 may be smaller than the outer diameter of the first flange portion 553 of the cylindrical body 55.

[0060] 7, the spacer member 63 is movable relative to the cover member 3. Alternatively, the spacer member 63 may be fixed to the cover member 3. For example, the spacer member 63 may be fixed to the annular portion 40 of the cover member 3 by engagement (e.g., screwing) or welding.

[0061] 8, the spacer member 63 may have an outer shell portion 633 and a reinforcing rib 635 arranged inside the outer shell portion 633. The reinforcing rib 635 reinforces the outer shell portion 633 and suppresses deformation of the outer shell portion 633. As illustrated in FIGS. 7 and 8, the spacer member 63 may have a receiving space 637 capable of receiving the recess 40d formed in the annular portion 40. The receiving space 637 is, for example, a space defined by the two reinforcing ribs 635 and the outer shell portion 633.

[0062] (Cover member 3) The cover member 3 has an annular portion 40 that connects the upper pipe portion 34 and the mounting portion 31. As illustrated in Fig. 9, the annular portion 40 may connect the mounting portion 31 and the upper pipe portion 34, connect the mounting portion 31 and the lower pipe portion 37, and connect the upper pipe portion 34 and the lower pipe portion 37. The upper surface of the annular portion 40 may be a surface parallel to the horizontal plane or a surface inclined relative to the horizontal plane. The annular portion 40 may be a flange.

[0063] 9, the lid member 3 is a part in which the attachment portion 31, the lower tubular portion 37, the upper tubular portion 34, and the annular portion 40 are integrated. In this case, the entire lid member 3 is attached to the outer container 2 by attaching the attachment portion 31 of the lid member 3 to the first opening portion 27 of the outer container 2. Alternatively, the lid member 3 may be divided into multiple parts, and each part may be placed in the outer container 2 in order.

[0064] In the example shown in FIG. 9, the mounting portion 31 extends downward from the outer edge 40u of the annular portion 40. The upper pipe portion 34 extends upward from the inner edge 40n of the annular portion 40. The lower pipe portion 37 extends downward from the inner edge 40n of the annular portion 40. In this case, the inner diameter of the mounting portion 31 can be significantly larger than the inner diameters of the upper pipe portion 34 and the lower pipe portion 37. In the example shown in FIG. 9, the central axis C1 of the upper pipe portion 34, the central axis C2 of the lower pipe portion 37, and the central axis C3 of the mounting portion 31 are arranged on a straight line.

[0065] The outer diameter D2 of the annular portion 40 is, for example, two or more times, three or more times, or four or more times the inner diameter D3 of the annular portion 40. When the difference between the outer diameter D2 of the annular portion 40 and the inner diameter D3 of the annular portion 40 is large, it becomes easy to place the replacement part 5 in the region below the annular portion 40, and it becomes easy to insert the replacement part 5 into the inside of the outer container 2.

[0066] In the example shown in Fig. 9, the upper pipe portion 34 has a first connecting portion 35. The first connecting portion 35 is connectable directly or indirectly to a first connector 111 of the beverage dispenser 110 (see, for example, Fig. 2). As exemplified in Fig. 18 etc., the first connecting portion 35 may be connected to the first connector 111 via a first closing member 70. In the example shown in Fig. 9, the first connecting portion 35 includes a third screw portion 35s (more specifically, a male screw portion formed on the outer circumferential surface of the upper pipe portion 34).

[0067] The size and shape of the first connecting portion 35 may be designed to correspond to the size and shape of a first connector of an existing beverage dispenser. For example, the size and shape of the first connecting portion 35 may be designed to correspond to a connector that can be connected to a general-purpose dispense head.

[0068] 9, the cover member 3 has a gas pipe section 41 through which gas can pass and a second connector 41c disposed on the gas pipe section 41. The second connector 41c can be connected to a connector of a gas supply tool (hereinafter referred to as "second connector").

[0069] 9, the gas pipe section 41 is arranged in the annular portion 40 of the cover member 3. The region where the gas pipe section 41 is arranged is completely separated from the region where the upper pipe section 34 is arranged, which allows the structures of the upper pipe section 34 and the gas pipe section 41 to be simplified.

[0070] The gas pipe section 41 may include a first pipe section 41a disposed outside the outer container 2. Alternatively, or additionally, the gas pipe section 41 may include a second pipe section exposed to the space within the outer container 2.

[0071] 9, the annular portion 40 has a recess 40d recessed downward relative to a top surface 40e of the annular portion 40. At least a portion of the gas pipe portion 41 is disposed in the recess 40d. In this case, at least a portion of the gas pipe portion 41 is protected by a wall surface that defines the recess 40d.

[0072] The upper end of the gas pipe portion 41 may be disposed at substantially the same height as the top surface 40e of the annular portion 40, or may be disposed at a position lower than the top surface 40e of the annular portion 40. In this case, the gas pipe portion 41 is suitably protected by the annular portion 40. Also, it is easy to cover the gas pipe portion 41 with a closing member such as a closing sheet (if necessary, see the second closing member 75 in FIG. 16).

[0073] 7, a gas inlet 40h is formed in the bottom wall of the recess 40d of the annular portion 40. Furthermore, a through-hole 63h of the spacer member 63 is disposed vertically below the gas inlet 40h. In this case, the gas supplied to the inside of the outer container 2 through the gas inlet 40h moves smoothly to the region below the spacer member 63.

[0074] In the example shown in FIG. 7, the seal member 52 of the replacement part 5 is attached to the lower pipe part 37, and the entire replacement part 5 is supported by the lower pipe part 37 via the seal member 52.

[0075] 9, the length L2 of the lower pipe portion 37 is, for example, 5 cm or less, 4 cm or less, or 3 cm or less. When the lower pipe portion 37 is a short pipe, the bag body 58 can be compactly arranged by utilizing the area below the annular portion 40 and the area below the lower pipe portion 37 when inserting the replacement part 5 into the outer container 2. However, in the embodiment, an embodiment in which the lower pipe portion 37 is a long pipe is not excluded.

[0076] In the example shown in Fig. 9, the lower tube portion 37 has a large diameter portion 37a and a small diameter portion 37c. The large diameter portion 37a has a larger outer diameter than the small diameter portion 37c, and the small diameter portion 37c has a smaller outer diameter than the large diameter portion 37a. In the example shown in Fig. 9, the large diameter portion 37a is thicker than the small diameter portion 37c. The inner diameter of the large diameter portion 37a may be the same as the inner diameter of the small diameter portion 37c.

[0077] In the example shown in FIG. 3, the seal member 52 of the replacement part 5 is attached to the small diameter portion 37c. The outer diameter of the small diameter portion 37c is larger than the smallest inner diameter of the seal member 52 before it is attached to the small diameter portion 37c. Due to the elastic properties of the seal member 52, the seal member 52 attempts to return to its original shape after being attached to the outer circumferential surface of the small diameter portion 37c. In this way, the elastic properties of the seal member 52 allow the seal member 52 to be stably held by the small diameter portion 37c. In the example shown in FIG. 3, the outer surface of the small diameter portion 37c is smooth. In this case, a good seal is ensured between the small diameter portion 37c and the seal member 52.

[0078] 3, the lower tubular portion 37 has a stopper surface 37b that defines the upper limit position of the cylindrical body 55. In the example shown in FIG. 3, the stopper surface 37b is configured by a step portion between the large diameter portion 37a and the small diameter portion 37c.

[0079] When the lower pipe portion 37 has the stopper surface 37b, the sealing member 52 can be suitably attached to the lower pipe portion 37 (more specifically, the small diameter portion 37c) by sliding the cylindrical body 55 and the sealing member 52 relative to the lower pipe portion 37 so that the cylindrical body 55 abuts against the stopper surface 37b. Alternatively, or additionally, when the beverage container 1 includes a spacer member 63, the cylindrical body 55 and the sealing member 52 may be slid relative to the lower pipe portion 37 so that the cylindrical body 55 (more specifically, the first flange portion 553 of the cylindrical body 55) abuts against the spacer member 63. In other words, the spacer member 63 may function as a stopper for the cylindrical body 55.

[0080] In the example shown in FIG. 10, the stopper surface 37b is located below the upper surface 27e of the first opening 27 and above the lower end 27g of the first opening 27.

[0081] (Seal ring 65) 10, the beverage container 1 includes a sealing ring 65 disposed between the first mouth 27 and the annular portion 40. The sealing ring 65 prevents gas from leaking through a gap between the outer container 2 and the lid member 3.

[0082] 10, the upper surface 27e of the first mouth portion 27 and the lower surface 40g of the annular portion 40 are in surface contact with each other while the seal ring 65 is compressed. This surface contact maintains the amount of compression of the seal ring 65 at an appropriate value. In other words, damage to the seal ring 65 due to excessive compression is prevented, and a stable sealing effect by the seal ring 65 is maintained.

[0083] 10 , the inner portion 401 of the annular portion 40 and the outer portion 402 of the annular portion 40 are connected via a weld 40w. When the inner portion 401 and the outer portion 402 are manufactured separately, it is easy to form a groove for receiving the seal ring 65 in the lower surface 40g of the annular portion 40. Note that the shape of the weld 40w may be any shape as long as it can suitably connect the inner portion 401 of the annular portion 40 and the outer portion 402 of the annular portion 40.

[0084] (Sealing member 52 of replacement part 5) In the example shown in FIG. 11 (see the lower diagram), the seal member 52 of the replacement part 5 has a lower lip portion 522. The lower lip portion 522 is in annular contact with the outer surface 37u of the lower pipe portion 37. The lower lip portion 522 also has a first outer peripheral surface 522u that receives the internal pressure of the bag body 58 (hereinafter referred to as the "first internal pressure"). The first outer peripheral surface 522u is exposed to the space SP2 within the bag body 58. When the first internal pressure of the bag body 58 increases, the force pressing the lower lip portion 522 toward the lower pipe portion 37 increases. As a result, leakage of the fluid (gas or beverage) in the bag body 58 from between the seal member 52 and the lower pipe portion 37 is effectively prevented.

[0085] As illustrated in FIG. 11 (see the upper diagram), before the sealing member 52 is attached to the lower pipe portion 37, the lower lip portion 522 preferably has an inner surface 522n that slopes inward as it extends downward.

[0086] 11 (see the lower diagram), the seal member 52 of the replacement part 5 has an upper lip portion 526. The upper lip portion 526 is in annular contact with the outer surface 37u of the lower pipe portion 37. The upper lip portion 526 also has a second outer circumferential surface 526u that is disposed outside the bag body 58.

[0087] 11, the top surface 55b of the cylindrical body 55 and the stopper surface 37b are in contact with each other. On the other hand, if a gap is formed between the top surface 55b and the stopper surface 37b, pressurized gas will enter the annular region AR2 between the cylindrical body 55 and the seal member 52 through the gap. When the pressure in the annular region AR2 increases, the force pressing the second outer peripheral surface 526u of the upper lip portion 526 toward the lower pipe portion 37 increases. Therefore, even if the pressure in the annular region AR2 increases, gas will not enter the bag body 58 from the annular region AR2.

[0088] As illustrated in FIG. 11 (see the upper diagram), before the seal member 52 is attached to the lower tube portion 37, the upper lip portion 526 preferably has an inner surface 526n that slopes inward as it extends upward.

[0089] 11 , an annular protrusion 524 is formed on the inner surface of the seal member 52 of the replacement part 5. When the seal member 52 is attached to the lower pipe part 37 (see the lower diagram), the annular protrusion 524 is located between the lower pipe part 37 and the cylindrical body 55. The lower pipe part 37 stably supports the replacement part 5 via the annular protrusion 524, which is compressed between the lower pipe part 37 and the cylindrical body 55.

[0090] 11 , the annular protrusion 524 is disposed between the lower lip portion 522 and the upper lip portion 526. In this case, multiple seals are ensured between the lower pipe portion 37 and the seal member 52. For example, even if a seal failure occurs in at least one of the lower lip portion 522 and the upper lip portion 526, fluid will not leak from the gap between the lower pipe portion 37 and the seal member 52.

[0091] In the example shown in FIG. 11 , the seal member 52 has an overall cylindrical shape. The length L3 of the seal member 52 in a direction parallel to the central axis C2 of the lower tubular portion 37 is, for example, 8 mm or more. The length L3 of the seal member 52 is, for example, 30 mm or less. When the length L3 of the seal member 52 is long, the seal member 52 is stably held by the lower tubular portion 37. When the length L3 of the seal member 52 is long, fluid is less likely to leak from the gap between the lower tubular portion 37 and the seal member 52. The length L4 of the contact surface between the seal member 52 and the cylindrical body 55 in a direction parallel to the central axis C2 of the lower tubular portion 37 is, for example, 6 mm or more. The length L3 of the contact surface is, for example, 28 mm or less. The long length L4 of the contact surface effectively prevents the seal member 52 from separating from the cylindrical body 55. It is preferable that the seal member 52 be firmly fixed to the cylindrical body 55.

[0092] (Cylindrical body 55) The cylindrical body 55 is disposed outside the sealing member 52 and holds the sealing member. The elastic modulus of the cylindrical body 55 is higher than that of the sealing member 52. The cylindrical body 55 is preferably made of a non-flexible member (in other words, a member that is substantially prevented from deforming). The cylindrical body 55 is made of a synthetic resin such as polyethylene or polypropylene. The cylindrical body 55 and the sealing member 52 are integrally molded, for example, in a molding die. Alternatively, the cylindrical body 55 and the sealing member 52 may be molded separately, and then the sealing member 52 may be attached to the cylindrical body 55.

[0093] 11 (see the lower diagram), when the seal member 52 is attached to the lower tubular portion 37, the inner circumferential surface of the cylindrical body 55 is maintained out of contact with the lower tubular portion 37. In other words, of the inner circumferential surfaces of the cylindrical body 55 and the seal member 52, only the inner circumferential surface of the seal member 52 comes into contact with the lower tubular portion 37. In this case, the sealing effect of the seal member 52 is maximized.

[0094] 11 (see the upper diagram), lower end portion 55g of cylindrical body 55 may cover lower lip portion 522 via gap G1. In this case, part or all of lower lip portion 522 is protected by lower end portion 55g of cylindrical body 55, thereby preventing or suppressing unintended damage to lower lip portion 522.

[0095] Upper end portion 55e of cylindrical body 55 may cover upper lip portion 526 via gap G2. In the example shown in Fig. 11, top surface 55b of cylindrical body 55 is located higher than the upper end of upper lip portion 526. In this case, upper end portion 55e of cylindrical body 55 protects the entire upper lip portion 526, thereby preventing or suppressing unintended damage to upper lip portion 526.

[0096] 11 (see the upper diagram), the cylindrical body 55 has a cylindrical portion 551 and a first flange portion 553. Additionally, the cylindrical body 55 may have a second flange portion 555 and an annular groove portion 557.

[0097] The cylindrical portion 551 is a portion that holds the seal member 52. The cylindrical portion 551 holds the seal member 52 and prevents excessive deformation of the seal member 52. The cylindrical portion 551 extends in a direction parallel to the central axis C2 of the lower pipe portion 37. The length of the cylindrical portion 551 in the direction parallel to the central axis C2 of the lower pipe portion 37 may be longer than the length L3 of the seal member 52, may be shorter than the length L3 of the seal member 52, or may be approximately the same as the length L3 of the seal member 52.

[0098] The first flange portion 553 functions as a mounting portion (more specifically, a welded portion) to which the bag body 58 is mounted. The first flange portion 553 and the bag body 58 are welded together by, for example, high-frequency welding. Alternatively, the first flange portion 553 and the bag body 58 may be welded together by heat welding or ultrasonic welding. In the example shown in FIG. 11 , the bag body 58 is welded to the upper surface of the first flange portion 553. Alternatively, the bag body 58 may be welded to the lower surface of the first flange portion 553. The first flange portion 553 has an inner edge connected to the tubular portion 551 and an outer edge which is a free edge.

[0099] Second flange portion 555 is disposed higher than first flange portion 553. In the example shown in FIG. 11, the outer diameter of second flange portion 555 is smaller than the outer diameter of first flange portion 553. In this case, second flange portion 555 is less likely to get in the way when attaching bag body 58 to first flange portion 553. Second flange portion 555 has an inner edge connected to tubular portion 551 and an outer edge which is a free edge.

[0100] The annular groove 557 is disposed between the first flange 553 and the second flange 555 .

[0101] The second flange portion 555 and / or the annular groove portion 557 are portions that are held or gripped by a machine or a jig. The presence of the second flange portion 555 (or the annular groove portion 557) makes it easier to manufacture the replacement part 5 and / or transport the replacement part 5.

[0102] (Bag body 58) The bag body 58 is attached to the cylindrical body 55. In the example shown in FIG. 12 , a mouth portion 58c (the portion indicated by hatching) of the bag body 58 is attached to a first flange portion 553 of the cylindrical body 55. The bag body 58 is placed in the internal space of the outer container 2 while attached to the cylindrical body 55. A beverage D (for example, an alcoholic beverage such as beer) is contained in the bag body 58. The bag body 58 can be filled with the beverage, and the beverage can be taken out from the bag body 58.

[0103] The bag body 58 is made of a synthetic resin such as polyethylene or polypropylene. The bag body 58 may be made of any one of a high-density polyethylene layer, a low-density polyethylene layer, a polyethylene terephthalate layer, and a nylon layer, or may be made of a laminate of these layers. To ensure light-blocking and / or oxygen-barrier properties, the bag body 58 may be made of a laminate film in which a light-blocking layer or an oxygen-barrier layer, such as an aluminum foil or an aluminum-deposited layer, is disposed between multiple synthetic resin layers. The bag body 58 may be made of a laminate film in which an oxygen-barrier layer, such as an ethylene-vinyl alcohol copolymer, is disposed between multiple synthetic resin layers. The bag body 58 may be made of a laminate film including a nylon layer, a polyethylene layer, and an aluminum layer. The material of the bag body 58 is not limited to the above examples.

[0104] (Removal prevention member 43) In the example shown in FIG. 13, the beverage container 1 is provided with a removal prevention member 43 that prevents the cover member 3 from being removed from the outer container 2.

[0105] The lid member 3 itself may be provided with a removal prevention member 43A that prevents the lid member 3 from being removed from the outer container 2. In the example shown in Fig. 13, the removal prevention member 43A has an engagement member 44 that can engage with the outer container 2. The engagement member 44 may be engageable with an engagement portion 28 (for example, an engagement recess) provided on the inner circumferential surface of the first opening 27 of the outer container 2.

[0106] 14, the position of the engaging member 44 can be changed between an engaging position Q1 where it engages with the engaging portion 28 of the outer container 2, and a retracted position Q2 where it is retracted from the engaging portion 28 of the outer container 2. When the engaging member 44 is in the engaging position Q1, the lid member 3 cannot be removed from the outer container 2. On the other hand, when the engaging member 44 is in the retracted position Q2, the lid member 3 can be removed from the outer container 2.

[0107] The removal prevention member 43A may have an operating member 45 that operates the engagement member 44. In the example shown in FIG.

[0108] In the example shown in FIG. 14 , the engagement between the outer container 2 and the engaging member 44 is released by pressing the operating member 45 downward. More specifically, pressing the operating member 45 downward moves the engaging member 44 from the engaging position Q1 to the retracted position Q2. Furthermore, when the downward pressure of the operating member 45 is released, the engaging member 44 returns from the retracted position Q2 to the engaging position Q1. In this case, the lid member 3 cannot be removed from the outer container 2 unless the operating member 45 is pressed downward. Therefore, the lid member 3 is prevented from being removed from the outer container 2 without using a dedicated removal tool 130. In the example shown in FIG. 14 , the removal tool 130 for removing the lid member 3 from the outer container 2 has a holding part 131 that holds the lid member 3 (more specifically, the attachment part 31) and a pressing part 132 (more specifically, a pressing protrusion) that presses the operating member 45. It goes without saying that the shape and structure of removal tool 130 are not limited to the example shown in FIG.

[0109] The removal prevention member 43A preferably has a conversion mechanism that converts the downward movement of the operating member 45 into the movement of the engaging member 44.

[0110] 14, the engagement member 44 has an inclined surface 44c, and the operation member 45 has a pressing surface 45c (e.g., a second inclined surface) that presses the inclined surface 44c. In this case, when the operation member 45 is moved downward, the pressing surface 45c presses the inclined surface 44c. As a result, the engagement member 44 having the inclined surface 44c moves from the engagement position Q1 to the retracted position Q2.

[0111] 14, the conversion mechanism that converts the downward movement of the operating member 45 into the movement of the engagement member 44 is a cam mechanism including an inclined surface 44c and a pressing surface 45c. Alternatively, the conversion mechanism may be a link mechanism having at least one swing arm.

[0112] The removal prevention member 43A may have a biasing member 46 that biases the engaging member 44 in a direction from the retracted position Q2 toward the engaging position Q1. In the example shown in FIG. 14 , the biasing member 46 is disposed on the cover member 3. More specifically, the biasing member 46 is disposed between the engaging member 44 and the lower tube portion 37.

[0113] 13, the spacer member 63 prevents the bag body 58 from directly contacting the removal prevention member 43A. A part of the removal prevention member 43A (for example, the engagement member 44) may be disposed so as to cross the spacer member 63.

[0114] (First modified example of removal prevention member 43) 13, the lid member 3 itself is provided with a removal prevention member 43A that prevents the lid member 3 from being removed from the outer container 2. In contrast, in the example shown in FIG. 15, the beverage container 1 is provided with a removal prevention member 43B that is separate from the lid member 3.

[0115] 15 , the removal prevention member 43B includes an annular member 47 that covers the outer peripheral surface of the attachment portion 31. The annular member 47 prevents access to the outer peripheral surface of the attachment portion 31, thereby preventing the attachment portion 31 of the lid member 3 from being removed from the first opening 27 of the outer container 2.

[0116] In the example shown in FIG. 15, the annular member 47 has an engaging portion 48 that can engage with the lid member 3 (more specifically, the mounting portion 31). When the engaging portion 48 is engaged with the lid member 3, the annular member 47 cannot be removed from the lid member 3. In the example shown in FIG. 15 (see the lower diagram), when the annular member 47 is rotated, the annular member 47 spins freely relative to the lid member 3. In this case, even if the annular member 47 is rotated, the lid member 3 cannot be removed from the first opening 27 of the outer container 2. For these reasons, the lid member 3 is prevented from being removed from the outer container 2 without using a dedicated removal tool or the like.

[0117] It is preferable that the annular member 47 does not have a weakened portion for breaking the annular member 47. In this case, the lid member 3 is effectively prevented from being removed from the outer container 2 without using a dedicated removal tool or dedicated breaking tool. However, in the embodiment, a mode in which a weakened portion is provided in the annular member 47 is not excluded.

[0118] (First closing member 70) As illustrated in Fig. 16, the beverage container 1 may have a first closing member 70 that can close an opening (hereinafter referred to as "second opening OP2") of the upper pipe portion 34. In the example shown in Fig. 16, the first closing member 70 is attached to the upper pipe portion 34 after the beverage container 1 (more specifically, the pouch 58) has been filled with beverage. Attaching the first closing member 70 to the upper pipe portion 34 prevents outside air from entering the beverage container 1 (more specifically, the pouch 58).

[0119] 16, the first closing member 70 is a cap 71. The cap 71 may have a top plate 71a, an annular wall 71b extending downward from the top plate 71a, and a female screw portion 71c provided on the annular wall 71b. The female screw portion 71c screws into a third screw portion 35s provided on the first connecting portion 35 of the upper tube portion 34.

[0120] The cap 71 may be made of resin or metal. Note that the first closing member 70 is not limited to the cap 71. The first closing member 70 may be a plug, a crown, or a closure seal.

[0121] (Second closing member 75) As illustrated in Figure 16, the beverage container 1 may have a second closure element 75 that covers the gas pipe 41. In the example shown in Figure 16, the second closure element 75 is a closure sheet. Alternatively, the second closure element 75 may be a cap or a bung.

[0122] (First Modification of the First Closing Member 70) 17, the first closure member 70 has a closure portion 72 that is movable from a closed position that prohibits the beverage D from being removed from the bag 58 to an open position that allows the beverage D to be removed from the bag 58. The closure portion 72 is moved from the closed position to the open position by being pressed or broken by the first connector 111 of the beverage removal tool 110.

[0123] 17, the closure portion 72 is a closure portion 72A (e.g., a plate or sheet) that can be broken by the first connector 111 of the beverage dispenser 110. The closure portion 72A may be covered by a protective member 73 (e.g., a protective seal) that can be removed from the first closure member 70.

[0124] The closing portion 72A is broken, for example, by the tip portion 111t of the first connector 111 (see FIG. 18). When broken, the closing portion 72A moves from the closed position to the open position.

[0125] 18, the first closure member 70 is a cap with a closing portion 72A. Alternatively, the first closure member 70 may be a plug with a closing portion 72A.

[0126] (Second Modification of the First Closing Member 70) 19, the first closure member 70 has a closure portion 72 that is movable from a closed position that prohibits removal of a beverage from the bag 58 to an open position that allows removal of a beverage from the bag 58. The closure portion 72 is pressed by the first connector 111 of the beverage removal tool 110, thereby moving from the closed position to the open position.

[0127] 19, the closing portion 72 is a first valve body 72B that can be pressed by the first connector 111 of the beverage dispenser 110. The first valve body 72B may be covered by a protective member 73 (e.g., a protective cap) that can be removed from the first closing member 70.

[0128] The first valve body 72B is pressed, for example, by the tip end 111t of the first connector 111 of the beverage extractor 110. In the example shown in Fig. 20, the first valve body 72B is pressed by the tip end 111t of the first connector 111, and thereby the first valve body 72B moves away from the first valve seat 710 of the first closing member 70. In this way, the first valve body 72B moves from the closed position to the open position.

[0129] The first closing member 70 may have a biasing member 74 (e.g., a spring) that biases the first valve body 72B toward the first valve seat portion 710. In this case, when the pressure on the first valve body 72B is released, the closing portion 72 automatically returns from the open position to the closed position.

[0130] 20, the first closing member 70 is a plug with a first valve body 72B. Alternatively, the first closing member 70 may be a cap with a first valve body 72B.

[0131] (Gas valve 42) 21, the cover member 3 has a gas valve 42 in addition to the gas pipe section 41. The gas valve 42 is a valve that can change its state between an open state in which the outside of the cover member 3 is fluidly connected to the inside of the cover member 3, and a closed state in which the outside of the cover member 3 is not fluidly connected to the inside of the cover member 3.

[0132] 21, a gas pipe section 41 is disposed in the annular portion 40, and a gas valve 42 is disposed in the gas pipe section 41. More specifically, the gas pipe section 41 has a second pipe section 41b exposed to the space inside the outer container 2, and the gas valve 42 is disposed in the second pipe section 41b.

[0133] 21, the gas valve 42 is a check valve that allows gas to move from the outside of the cover member 3 to the inside of the cover member 3 and prohibits gas from moving from the inside of the cover member 3 to the outside of the cover member 3. In this case, by making the gas supply pressure to the gas pipe section 41 higher than the internal pressure of the outer container 2, gas can be supplied from the outside of the cover member 3 to the inside of the cover member 3. Furthermore, when the gas supply tool is removed from the gas pipe section 41, the internal pressure of the outer container 2 causes the gas valve 42 to automatically close.

[0134] Alternatively, as illustrated in FIG. 22, the gas valve 42 may be a valve that allows gas to move from the outside of the cover member 3 to the inside of the cover member 3, and from the inside of the cover member 3 to the outside of the cover member 3.

[0135] 22, the gas valve 42 has a second valve body 421 disposed inside the gas pipe section 41 and a second valve seat portion 423 disposed in the gas pipe section 41. The second valve body 421 can be pressed by the second connector 121 of the gas supply tool 120. When the second valve body 421 is pressed by the tip portion 121t of the second connector 121, the second valve body 421 moves away from the second valve seat portion 423. In this way, the state of the gas valve 42 is switched from a closed state to an open state.

[0136] The cover member 3 may have a biasing member 39 (for example, a spring) that biases the second valve body 421 toward the second valve seat portion 423. In this case, when the pressure on the second valve body 421 is released, the state of the gas valve 42 automatically returns from the open state to the closed state.

[0137] In the example shown in FIG. 22, the second valve body 421 and the biasing member 39 are disposed inside the first pipe portion 41a disposed outside the outer container 2.

[0138] (Second embodiment) A method for assembling a beverage container 1 according to the second embodiment will be described with reference to Figures 1 to 26. Figure 23 is a schematic cross-sectional view showing a state during an insertion step. Figure 24 is a schematic cross-sectional view showing a state during a beverage filling step. Figure 25 is a flowchart showing an example of a method for assembling a beverage container according to the second embodiment. Figure 26 is a flowchart showing an example of a method for handling a beverage container according to the second embodiment.

[0139] The beverage container assembly method of the second embodiment constitutes part of the beverage container handling method of the second embodiment. The beverage container 1 assembled by the beverage container assembly method of the second embodiment may be the beverage container 1 of the first embodiment, or may be another beverage container. Each component of the beverage container 1 has already been described in the first embodiment, so repeated description of each component of the beverage container 1 will be omitted.

[0140] In a first step ST1, an outer container 2 having a container body 22 and a first opening 27 is prepared (see, for example, FIG. 5). The first step ST1 is a first preparation step. The outer container 2 prepared in the first preparation step is preferably a rigid container (for example, a stainless steel container). The outer container 2 may be a new container, or may be a reusable container prepared by disassembling a beverage container collected from a user.

[0141] In a second step ST2, a lid member 3 is prepared. The second step ST2 is a second preparation step. The lid member 3 prepared in the second preparation step may be a new lid member 3, or may be a reusable item prepared by disassembling a beverage container collected from a user.

[0142] As illustrated in Figure 9, the lid member 3 prepared in the second preparation step has (1) an attachment portion 31 that can be attached to the first opening portion 27, (2) an upper pipe portion 34 that is positioned outside the outer container 2, (3) an annular portion 40 that protrudes outward from the upper pipe portion 34 and connects the upper pipe portion 34 and the attachment portion 31, and (4) a lower pipe portion 37 that extends downward from the annular portion 40.

[0143] The lid member 3 prepared in the second preparation step may have a gas pipe section 41 arranged in the annular portion 40. The lid member 3 may have a gas valve 42 (see Figures 21, 22, etc.) arranged in the gas pipe section 41. The lid member 3 prepared in the second preparation step may also have a removal prevention member 43 (see Figure 13, etc.).

[0144] In a third step ST3, a replacement part 5 is prepared. The third step ST3 is a third preparation step. The replacement part 5 prepared in the third preparation step is a brand new part.

[0145] As illustrated in FIG. 12, the replacement part 5 includes (1) a sealing member 52, (2) a cylindrical body 55 that holds the sealing member 52, and (3) a bag body 58 that is attached to the cylindrical body 55 and that contains a beverage.

[0146] The first step ST1 (first preparation step), the second step ST2 (second preparation step), and the third step ST3 (third preparation step) may be performed in any order.

[0147] In a fourth step ST4, the replacement part 5 is attached to the lower pipe portion 37. The fourth step ST4 is a first attachment step. As illustrated in FIG. 3 and other figures, the first attachment step includes sliding the seal member 52 and the cylindrical body 55 relative to the lower pipe portion 37. In this specification, "slide" refers to sliding relative to the lower pipe portion 37. Therefore, "slide" includes linearly moving the seal member 52 relative to the lower pipe portion 37, and linearly moving the lower pipe portion 37 relative to the seal member 52.

[0148] 3, the lower tubular portion 37 has a large diameter portion 37a, a small diameter portion 37c, and a stopper surface 37b disposed between the large diameter portion 37a and the small diameter portion 37c. In this case, in the first attachment step, the seal member 52 is attached to the small diameter portion 37c. The stopper surface 37b prevents the cylindrical body 55 of the replacement part 5 from moving upward beyond the stopper surface 37b.

[0149] As illustrated in FIG. 4, the first mounting step includes bringing the seal member 52 into annular contact with the outer surface 37u of the lower pipe portion 37 at the mounting position P.

[0150] The first attachment step includes attaching the seal member 52 to the lower pipe portion 37 by utilizing the frictional force acting between the seal member 52 and the outer surface 37u of the lower pipe portion 37. Since the replacement part 5 and the lower pipe portion 37 are not glued or welded to each other, it is easy to remove the replacement part 5 from the lower pipe portion 37 after the beverage container has been collected.

[0151] 11 , in the first attachment step, the sealing member 52 may be attached to the lower pipe portion 37 at a position below the spacer member 63. More specifically, the lower pipe portion 37 may be inserted into the through-hole portion 63h of the spacer member 63, and then the sealing member 52 may be attached to the lower pipe portion 37 at a position below the spacer member 63. Alternatively, in the second preparation step (second step ST2), the cover member 3 with the spacer member 63 may be prepared, and in the first attachment step (fourth step ST4), the sealing member 52 may be attached to the lower pipe portion 37 at a position below the spacer member 63.

[0152] 23 , in a fifth step ST5, the replacement part 5 and the lower pipe portion 37 are inserted into the outer container 2. The fifth step ST5 is an insertion step. More specifically, the insertion step includes inserting the lower pipe portion 37, the seal member 52 attached to the lower pipe portion 37, the cylindrical body 55 supported by the lower pipe portion 37 via the seal member 52, and the bag body 58 attached to the cylindrical body 55 into the outer container 2 via the first opening 27.

[0153] The lower pipe portion 37 is a long, thin member, and its outer diameter is relatively small. This allows the outer diameter of the replacement part 5 attached to the lower pipe portion 37 to be small. In the example shown in FIG. 23 , the size of the first opening 27 is set to be large due to the presence of the annular portion 40. Therefore, the ability to reduce the outer diameter of the replacement part 5 and the large size of the first opening 27 allow the entire replacement part 5 to be smoothly inserted into the outer container 2 through the first opening 27.

[0154] In a sixth step ST6, the attachment portion 31 of the lid member 3 is attached to the first opening 27 of the outer container 2. The sixth step ST6 is a second attachment step. More specifically, in the second attachment step, the attachment portion 31 of the lid member 3 is screwed into the first opening 27 of the outer container 2.

[0155] In a seventh step ST7, the beverage container 1 is filled with a beverage. The seventh step ST7 is a beverage filling step. In the beverage filling step, the bag 58 placed in the outer container 2 is filled with a beverage.

[0156] In the example shown in FIG. 24, the beverage filling step includes filling the bag 58 with a beverage (e.g., an alcoholic beverage such as beer) via the upper tube portion 34 and the lower tube portion 37 (see arrow E1).

[0157] The beverage filling step may include discharging gas from the space SP3 between the outer container 2 and the pouch 58 to the outside of the outer container 2 via the gas pipe 41 (see arrow E2). Alternatively, the beverage filling step may include pressing the operating member 45 and discharging gas from the space SP3 between the outer container 2 and the pouch 58 to the outside of the outer container 2 via the hole where the operating member 45 was located.

[0158] 24, a spacer member 63 is disposed between the annular portion 40 and the tubular body 55. The spacer member 63 prevents the bag body 58 from being excessively deformed toward the annular portion 40 when the bag body 58 expands due to being filled with beverage. In this way, damage to the bag body 58 is prevented.

[0159] 24, the spacer member 63 prevents the bag body 58 from contacting the removal prevention member 43 when the bag body 58 is inflated. In this way, damage to the bag body 58 is prevented.

[0160] In an eighth step ST8, the first closing member 70 is attached to the upper pipe portion 34. The eighth step ST8 is a third attachment step. In the third attachment step, the first closing member 70, which is capable of closing the second opening OP2 of the upper pipe portion 34, is attached to the upper pipe portion 34.

[0161] In the third attachment step, the first closure member 70 attached to the upper pipe portion 34 may have a closure portion 72 that is movable from a closed position that prohibits removal of a beverage from the bag 58 to an open position that allows removal of a beverage from the bag 58 (see FIGS. 17, 19, etc.). The closure portion 72 moves from the closed position to the open position when pressed or broken by the first connector 111 of the beverage removal tool 110. As exemplified in FIGS. 17 and 19, the closure portion 72 may be covered by a protective member 73.

[0162] Additionally, the method of assembling the beverage container in the embodiment may include attaching a second closure member 75 covering the gas pipe portion 41 to the annular portion 40 of the lid member 3 or the gas pipe portion 41 .

[0163] (How to take out beverages) Next, a step of removing a beverage from the beverage container 1 (in other words, a method of removing a beverage from the beverage container 1) will be described. The step of removing a beverage from the beverage container 1 constitutes part of a method of handling the beverage container 1. In other words, the method of handling the beverage container 1 includes a step of removing a beverage from the beverage container 1.

[0164] After the eighth step ST8 is performed, in the ninth step ST9, the beverage is removed from the beverage container 1. The ninth step ST9 is a beverage removal step. In the beverage removal step, the beverage is removed from the bag body 58 placed in the outer container 2. Each of Figures 2, 18, and 20 shows the beverage removal step being performed. The beverage is removed from the bag body 58 using the beverage removal tool 110 and the gas supply tool 120.

[0165] In the beverage extraction process, first, in sub-step ST9-1, the first connector 111 of the beverage extractor 110 is fluidly connected to the upper pipe portion 34 of the lid member 3, and the second connector 121 of the gas supply tool 120 is fluidly connected to the gas pipe portion 41 of the lid member 3. Sub-step ST9-1 is a connection process. The first connector 111 may be directly or indirectly attached to the upper pipe portion 34 of the lid member 3 by a screw method. Alternatively, the first connector 111 may be directly or indirectly attached to the upper pipe portion 34 of the lid member 3 by a one-touch method. Moreover, the second connector 121 may be attached to the gas pipe portion 41 by a screw method or a one-touch method.

[0166] In the example shown in FIG. 2, sub-step ST9-1 includes directly attaching the first connector 111 of the beverage dispenser 110 to the upper pipe portion 34 of the cover member 3.

[0167] Alternatively, sub-step ST9-1 may include indirectly attaching the first connector 111 of the beverage dispenser 110 to the upper pipe portion 34 of the lid member 3. More specifically, as illustrated in FIGS. 18 and 20, the first connector 111 of the beverage dispenser 110 may be attached to a first closure member 70 disposed on the upper pipe portion 34 of the lid member 3. In the example illustrated in FIGS. 18 and 20, when the first connector 111 is attached to the first closure member 70, the tip 111t of the first connector 111 presses or breaks the closure portion 72. In this way, the closure portion 72 moves from the closed position to the open position. In this case, when the closure portion 72 moves from the closed position to the open position, intrusion of outside air into the bag body 58 is prevented or suppressed.

[0168] Secondly, in the beverage taking-out step, in sub-step ST9-2, gas (e.g., air) is supplied from the gas supply tool 120 to the space SP3 between the outer container 2 and the bag body 58 via the gas pipe part 41. Sub-step ST9-2 is a gas supplying step.

[0169] In the gas supplying step, the gas supplied to the space SP3 via the gas pipe section 41 presses the bag body 58 so that the bag body 58 contracts.

[0170] Thirdly, in the beverage taking-out step, in sub-step ST9-3, the beverage is taken out from the bag body 58. The beverage is taken out via the lower pipe portion 37 of the cover member 3 and the upper pipe portion 34 of the cover member 3.

[0171] In the beverage removal method of the embodiment, a beverage is removed from the bag body 58 by supplying gas to the space SP3 between the outer container 2 and the bag body 58. Therefore, the beverage in the bag body 58 does not come into contact with the supply gas (e.g., air) supplied via the gas pipe section 41. Therefore, the taste, texture, etc. of the beverage are not deteriorated due to contact of the beverage with the supply gas. Furthermore, if the beverage is a sparkling beverage such as beer, the feel of the foam is not deteriorated.

[0172] Furthermore, in the beverage dispensing method of the embodiment, air can be used as the gas supplied to the space SP3 between the outer container 2 and the bag 58. Therefore, unlike conventional beverage dispensing methods, there is no need to prepare a carbon dioxide gas cylinder. Note that using air as the gas supplied to the space SP3 is an optional configuration. In other words, in the embodiment, it is not excluded to use a gas other than air (for example, carbon dioxide gas) as the gas supplied to the space SP3 between the outer container 2 and the bag 58.

[0173] When the outer container 2 is made of stainless steel, the outer container 2 has extremely high durability and corrosion resistance, and also has excellent light-blocking properties. Therefore, the outer container 2 with the bag body 58 disposed therein may be stored outdoors.

[0174] (Method of disassembling beverage container 1) Next, a description will be given of the step of disassembling the beverage container 1 (in other words, a method of disassembling the beverage container 1). The step of disassembling the beverage container 1 constitutes a part of a method of handling the beverage container 1. In other words, the method of handling the beverage container 1 includes the step of disassembling the beverage container 1.

[0175] After the ninth step ST9 is performed, the beverage container 1 is disassembled in a tenth step ST10. The tenth step ST10 is a disassembly step.

[0176] The disassembly step (tenth step ST10) includes removing the cover member 3 from the outer container 2 and removing the replacement part 5 from the lower tube portion 37 of the cover member 3.

[0177] When the beverage container 1 is provided with a removal prevention member 43, the lid member 3 is removed from the outer container 2 with the engagement member 44 of the removal prevention member 43 retracted from the engagement portion 28 of the outer container 2 (see Figure 14). Alternatively, the lid member 3 may be removed from the outer container 2 after the removal prevention member 43 has been broken.

[0178] Removing the replacement part 5 from the lower tubular portion 37 of the cover member 3 involves sliding the sealing member 52 and cylindrical body 55 of the replacement part 5 along the lower tubular portion 37 in a direction toward the lower end of the lower tubular portion 37. In the disassembly process, the replacement part 5 can be removed from the lower tubular portion 37 simply by sliding the sealing member 52 and cylindrical body 55 along the lower tubular portion 37. Therefore, the task of removing the replacement part 5 from the lower tubular portion 37 can be performed quickly and easily.

[0179] The lid member 3 and outer container 2 from which the replacement part 5 has been removed are preferably reused the next time beverage is filled. On the other hand, it is preferable that a replacement part 5 that has been used once is replaced with a new replacement part (more specifically, a brand new replacement part). Note that, since the structure of the replacement part 5 in the embodiment is simple, the manufacturing cost of the replacement part 5 is low.

[0180] In the embodiment, the bag body 58 is filled with the beverage, and the beverage does not come into direct contact with the reusable outer container 2. This reliably ensures the safety of the beverage. Furthermore, since the beverage does not come into direct contact with the reused outer container 2, the adhesion of organic matter (dirt) or odors to the inside of the outer container 2 is suppressed. As a result, the outer container 2 can be easily managed when it is collected and reused. Furthermore, the process of cleaning the outer container 2 can be simplified.

[0181] The present invention is not limited to the above-described embodiments or modifications, and it is clear that each embodiment or modification can be appropriately modified or changed within the scope of the technical concept of the present invention. Furthermore, various techniques used in each embodiment or modification can be applied to other embodiments or modifications as long as no technical contradiction occurs. Furthermore, optional additional configurations in each embodiment or modification can be omitted as appropriate. [Explanation of symbols]
