<2-2. Inner bag>
The inner bag 2 has a bag body 20 and a mouth portion 10 attached to the bag body 20. The bag body 20 is made of a flexible material, and is made of a synthetic resin in this embodiment. Accordingly, the bag body 20 can be folded into a flat shape in an empty state, but as shown in FIG. 1, the bag body 20 is three-dimensional so as to form an internal space S1 that is large enough to accommodate the contents. Can be spread. The internal space S <b> 1 here means the internal space of the main body portion (container main body) of the inner bag 2 formed by the bag main body 20 and the mouth portion 10.

  FIG. 3 shows an external perspective view of the vicinity of the mouth 10. The mouth portion 10 has a cylindrical portion 11 and a base portion 12 connected to one end 11 a in the axial direction of the cylindrical portion 11. The structure of the mouth portion 10 can be easily understood with reference to FIGS. 7A and 7B. The cylindrical portion 11 is open at both ends in the axial direction, and the outer diameter and inner diameter of the cylindrical portion 11 are generally constant along the axial direction. The base portion 12 is an annular portion, and is a member that extends radially outward from the end portion 11a of the cylindrical portion 11 over the entire circumferential direction. That is, the base portion 12 has a flange shape with respect to the cylindrical portion 11.

  On the outer peripheral surface of the cylindrical portion 11, projecting portions 13 and 14 that are arranged in parallel in the axial direction are formed. The protruding portion 13 is an annular portion that extends radially outward from the base portion 12 over the entire circumferential direction of the cylindrical portion 11 at a predetermined interval in the axial direction. The projecting portion 14 is an annular portion that extends radially outward from the projecting portion 13 on the opposite side of the base portion 12 along the axial direction along the entire circumferential direction of the cylindrical portion 11. The cross sections (transverse sections) in the axial direction of the protrusions 13 and 14 have substantially the same shape. The protruding portions 13 and 14 are both flanged with respect to the cylindrical portion 11. As will be described later, when the inner bag 2 is set in the outer box 3, the mouth portion 55 of the outer case 3 is inserted into the space surrounded by the base portion 12 and the protruding portion 13. It is fixed in a state protruding to the outside.

  On the outer peripheral surface of the cylindrical portion 11, a screw thread 15 extending in a spiral shape is formed at a position opposite to the protruding portion 13 along the axial direction from the protruding portion 14. The screw thread 15 is screwed with a screw thread 46 formed on the cap 40 described later.

  The cylindrical portion 11, the base portion 12, the protruding portions 13 and 14, and the screw thread 15 included in the mouth portion 10 are integrally configured. The material of the mouth 10 is not particularly limited as long as it can function as the mouth 10, but is made of a hard synthetic resin in the present embodiment. The bag main body 20 is formed with an opening 20a having substantially the same shape as the outer diameter of the cross section of the protrusions 13 and 14, and the cylindrical portion 11 extends from the inside of the bag main body 20 to the opening 20a. 14 and the screw thread 15 so as to protrude outward. The outer diameter of the base 12 is larger than the outer diameter of the opening 20a. At this time, the base 12 cannot pass through the opening 20a. Therefore, when the cylindrical portion 11 is inserted into the opening 20a, the base portion 12 comes into contact with the bag body 20 and stops. In the present embodiment, the peripheral portion of the opening 20 a in the bag body 20 is thermally welded to the base 12. As a result, the bag body 20 and the mouth portion 10 are firmly connected, and the body portion (container body) of the inner bag 2 is formed by both members. In addition, the outer diameter of the screw thread 15 is smaller than the outer diameter of the base 12 and the protrusions 13 and 14. Therefore, the screw thread 15 does not prevent insertion of the cylindrical portion 11 into the opening 20a.

  An inner cylinder 30 shown in FIGS. 4 to 6 is inserted into the cylindrical portion 11. More specifically, the inner cylinder 30 has a cylindrical side wall 31, and the side wall 31 is inserted into the cylindrical portion 11. The inner cylinder 30 further includes a wall member 32 that spreads in an oblique cross-section with respect to the side wall 31 in the vicinity of the axial center of the side wall 31. That is, the wall member 32 obliquely intersects with the central axis of the side wall 31. The diameter of the side wall 31 of the present embodiment changes with the wall member 32 as a boundary. More specifically, the outer diameter of a portion (hereinafter referred to as an inner portion) 311 of the side wall 31 that is closer to the cylindrical portion 11 than the wall member 32 is larger than the outer diameter of a portion 312 on the opposite side (hereinafter referred to as an outer portion). The same applies to the inner diameter. The outer diameter and inner diameter of the inner portion 311 are generally constant along the axial direction. Moreover, the outer diameter and inner diameter of the outer portion 312 are also substantially constant along the axial direction.

  The internal space of the side wall 31 is separated into two spaces S21 and S22 in the axial direction by a wall member 32 that spreads in the side wall 31. The space S21 is an internal space of the inner part 311 and the space S22 is an internal space of the outer part 312. The inner portion 311 is open at the end on the opposite side of the wall member 32 in the axial direction. Similarly, the outer portion 312 is also open at the opposite end of the wall member 32 in the axial direction.

  The inner portion 311 is formed with a spout S3 that allows the internal space S21 to communicate with the outside. The spout S3 communicates with the inside of the bag body 20 via the internal space S21. Therefore, the contents accommodated in the inner space S1 of the inner bag 2 can be taken out through the spout S3. In the present embodiment, the downstream end of the spout S <b> 3 is defined by the wall member 32. The angle range θ (see FIG. 5) in which the spout S3 spreads in the circumferential direction with respect to the central axis of the side wall 31 is preferably θ <180 °, more preferably θ <160 °, and θ <140. More preferably, it is °. If the spout S3 is too large, the contents may jump out of the spout S3 in various directions, particularly when the contents are gel-like beads, but the contents vary within the above numerical range. It becomes difficult to jump out in the direction. On the other hand, if the spout S3 is too small, the contents may be clogged. Therefore, 60 ° ≦ θ is preferable, 80 ° ≦ θ is more preferable, and 100 ° ≦ θ is further satisfied. preferable. In this embodiment, θ = 120 °.

  The side wall 31 can advance and retreat in the cylindrical portion 11 along the axial direction, thereby opening and closing the spout S3. The side wall 31 moves between the open position (see FIG. 7A) where the spout S3 is opened and the closed position (see FIG. 7B) where the spout S3 is closed while sliding in the cylindrical portion 11. The open position is a position where the side wall 31 has been advanced so as to be pulled out from the internal space S1 through the cylindrical portion 11, and at this position, the spout S3 reaches the outside of the cylindrical portion 11 along the axial direction, Is exposed to the external space. The closed position is a position where the side wall 31 is retracted to the inner space S1 side. In this position, the spout S3 is surrounded by the side wall 31 or inserted into the bag body 20, and the whole is accommodated in the inner space S1. Is done.

  In the above-mentioned open position, the contents can be taken out through the spout S3. When the contents are taken out, the contents travel in the inner space S21 of the inner cylinder 30 along the axial direction B1 of the inner portion 311 (hereinafter referred to as a course direction), collide with the wall member 32, change its direction, and It falls downward from the exit S3. In the present embodiment, the wall member 32 is inclined in the direction from the inner side of the spout S3 (upper side in the state of FIG. 7A) toward the spout S3 along the course direction B1. When the inclination angle of the wall member 32 with respect to the course direction B1 is α (see FIG. 4), it is preferably 30 ° ≦ α ≦ 60 °, more preferably 40 ° ≦ α ≦ 50 °. In form, α = 45 °. In particular, when the contents are gel-like beads, the contents flow out from the spout S3 in the direction indicated by the solid line in FIG. 7A, that is, in the radial direction of the inner cylinder 30. Thereby, the contents are prevented from jumping out from the spout S3 in the direction indicated by the broken line in FIG. 7A, and the contents are less likely to spill.

  The diameter of the passage of the contents in the internal space S21 changes due to the presence of the wall member 32 in the vicinity of the spout S3. When the content is granular like beads, it is preferable that 1.0 <r / R, where r is the minimum diameter of the passage of the content and R is the maximum diameter of the content. The maximum diameter R of the content is the maximum value among the variations when the size of the content varies. In this embodiment, the maximum value of the diameter of the spherical beads that are the contents is R. Further, in the present embodiment, the minimum diameter r of the passage of contents is the length of a perpendicular line extending from the center C of the edge that defines the upstream end of the spout S3 in the inner portion 311 to the wall member 32. It is. According to the above numerical range of r / R, the clogging of the contents in the internal space S21 is suppressed. Moreover, it is preferable that r / R ≦ 2.0. In this numerical range, a large amount of beads are prevented from flowing out, and the contents are less likely to spill.

  As shown in FIGS. 4 to 6, projections 35 and 36 projecting radially outward are formed on the outer surface of the inner portion 311 of the side wall 31. The protrusions 35 and 36 serve as stoppers for preventing the side wall 31 from falling off the cylindrical portion 11 of the mouth portion 10. The protrusions 35 and 36 are arranged at a predetermined interval in the circumferential direction at the inner end of the inner portion 311 (with an interval of 180 ° in the present embodiment). The outer diameter of the inner portion 311 of the inner cylinder 30 is smaller than the inner diameter of the cylindrical portion 11 of the mouth portion 10, and the outer diameter of the inner cylinder 30 at the positions of the projections 35 and 36 is larger than the inner diameter of the cylindrical portion 11. large. Therefore, when an external force is applied so that the side wall 31 is pulled out from the internal space S1 through the mouth portion 10, the movement stops when the projections 35 and 36 come into contact with the base portion 12 of the mouth portion 10 to prevent dropping. Is done.

  The inner portion 311 is formed with slit-shaped cuts 37 and 38 extending from the inner end along the course direction B1. The notches 37 and 38 are arranged at a predetermined interval in the circumferential direction (in the present embodiment, at an interval of 180 °). In addition, the notches 37 and 38 are arranged at a predetermined interval in the circumferential direction from the protrusions 35 and 36 (in the present embodiment, with an interval of 90 °). The cuts 37 and 38 allow the inner portion 311 to be bent into a flat shape so that the cross section (axial cross section) is reduced in diameter in the direction connecting the protrusions 35 and 36. Thereby, the inner cylinder 30 can be easily inserted into the cylindrical part 11 of the mouth part 10 from the inner end side. In order to achieve such an effect, the line connecting the circumferential centers of the protrusions 35 and 36 and the line connecting the circumferential centers of the notches 37 and 38 preferably cross each other and are substantially orthogonal. More preferably.

  The side wall 31, the wall member 32, the protrusions 35 and 36, and the protrusion 39a (described later) included in the inner cylinder 30 are integrally configured. The material of the inner cylinder 30 is not particularly limited as long as the function as the inner cylinder 30 can be achieved, but in the present embodiment, it is made of a hard synthetic resin.

  As shown in FIGS. 7A and 7B, a cap 40 shown in FIGS. 8 to 10 is connected to the outer end of the inner cylinder 30. 8 is a side view of the cap 40, FIG. 9 is a perspective view of the cap 40 viewed from the outside, and FIG. 10 is a perspective view of the cap 40 viewed from the inside. 8 to 10 show external views of the cap 40 alone. As shown in FIGS. 7A and 7B, the cap 40 is finally fixed to the inner cylinder 30 and assembled as one component. .

  The cap 40 includes a cylindrical side wall 41, an upper surface part 42 that closes an opening at the outer end of the side wall 41, and a cylindrical inner ring part 43 that hangs down from the upper surface part 42 in the side wall 41. The inner ring portion 43 is disposed coaxially with the side wall 41 and has a smaller diameter than the side wall 41. Further, the diameter of the inner ring portion 43 is substantially equal to the diameter of the outer portion 312 of the inner cylinder 30, and one of the inner ring portion 43 and the outer portion 312 is inserted into the other and fitted. Further, in order to prevent the cap 40 from falling off from the inner cylinder 30, protrusions and corresponding holes are formed on the opposing surfaces of the inner ring portion 43 and the outer portion 312 in the inserted state. In the present embodiment, since the outer portion 312 is inserted into the inner ring portion 43, the protrusion 39 a and the hole 39 b are formed on the outer peripheral surface of the outer portion 312, and the protrusion 39 a is formed on the inner peripheral surface of the inner ring portion 43. A protrusion 45b corresponding to the hole 45a and the hole 39b is formed.

  A thread 46 corresponding to the thread 15 of the mouth portion 10 is formed on the inner peripheral surface of the side wall 41. Therefore, when the inner cylinder 30 is pushed in the axial direction into the deep part of the inner space S1 through the mouth portion 10, the thread 15 and the thread 46 come into contact with each other, and a state in which the inner cylinder 30 cannot be pushed further occurs. In this state, when the cap 40 is rotated around the central axis together with the inner cylinder 30, the screw thread 15 and the screw thread 46 are screwed, and the cap 40 is fixed to the mouth portion 10. At this time, since the inner cylinder 30 is accommodated in the internal space S1 formed by the mouth portion 10 and the bag body 20, and is further covered by the cap 40, it is confined in the space S1. Thereby, the inner cylinder 30 is locked in the closed position mentioned above. Further, when an operation opposite to the above operation is performed, the coupled state of the screw thread 15 and the screw thread 46 is released, and the inner cylinder 30 is pulled out from the mouth portion 10 and is in an open state. As is clear from the above configuration, the cap 40 is detachable from the mouth portion 10.

  Note that the outer diameter of the inner portion 311 of the inner cylinder 30 is slightly smaller than the inner diameter of the cylindrical portion 11 of the mouth portion 10, and therefore, the inner portion 311 can easily rotate within the cylindrical portion 11. Therefore, when the operation of pulling out the inner cylinder 30 to the open position is performed as described above, the spout S3 does not always face downward. Therefore, the outer surface of the upper surface portion 42 is provided with an indicia indicating the position of the spout S3. In this embodiment, an arrow pattern as shown in FIG. 9 is formed. The operator can easily set the spout S3 to face downward by pulling out the cap 40 and the inner cylinder 30 while adjusting the arrow so that the arrow faces downward.

  The side wall 41, the upper surface portion 42, the inner ring portion 43, the protrusion 45 b and the screw thread 46 included in the cap 40 are integrally configured. The material of the cap 40 is not particularly limited as long as it can function as the cap 40, but is made of a hard synthetic resin in this embodiment.

  The above-described mouth portion 10, the inner cylinder 30, and the cap 40 constitute a structure D that forms an outlet for taking out contents from the inner bag 2.

<2-3. Outer box>
Next, the structure of the outer box 3 will be described. The material of the outer box 3 is not particularly limited, but the outer box 3 of the present embodiment is made of paper, more specifically, cardboard. As shown in FIG. 2, the outer box 3 is formed in a rectangular parallelepiped shape. When assembling the bag-in-box 1, the inner bag 2 with the mouth 10 closed with the cap 40 is accommodated in the outer box 3, and then the opening containing the inner bag 2 is stopped with tape or the like. Pack it. In the use state, the mouth portion 10 is set so as to protrude from the outer box 30, but at the time of packing, the inner bag 2 is completely accommodated in the outer box 3 for transportation and transportation. As shown in FIG. 11, an opening 51 is formed in one side surface portion 50 of the outer box 3. When packing the inner bag 2 in the outer box 3, the structure D serving as a content outlet is disposed in the outer box 3 so as to face the opening 51.

  The opening 51 is formed by making a cut in the side surface portion 50. More specifically, the opening 51 includes window portions 52a and 52b that can be opened like a double-opening window, and a circular portion 53 that is disposed below a mating surface of the window portions 52a and 52b. When the bag-in-box 1 is used, the circular portion 53 is removed along the cut. Further, the windows 52a and 52b are separated along the cuts, and both the windows 52a and 52b are opened. Thereby, the opening formed by removing the circular part 53 and the larger opening formed by opening the window parts 52a and 52b are connected. Then, the structure D is pulled out from the inside of the outer box 3 through the openings corresponding to the window parts 52a and 52b, and is hooked and fixed to the opening corresponding to the circular part 53. More specifically, a portion (referred to as a mouth portion 55) surrounding the circular portion 53 in the side surface portion 50 is inserted into a space surrounded by the base portion 12 and the protruding portion 13 of the mouth portion 10 described above. Thereafter, the use of the bag-in-box 1 can be started by closing the windows 52a and 52b.

<3. Features>
As described above, the structure D of the outlet according to the above embodiment realizes high sealing performance by the cap 40 while having a simple configuration with a pull-out type. In addition, in the case of a cock-type outlet as in Patent Documents 1 and 2, since it is generally not said that the sealing performance is complete, before starting the use of the container, with a cap that is a separate part from the parts that constitute the cock, The container side mouth must be sealed. In use, the cap must be removed and replaced with the components that make up the cock. On the other hand, according to the structure D of the above embodiment, such a problem does not exist and the number of parts is reduced.

  Moreover, although the structure D of the said embodiment can be utilized for the container which accommodates various contents, it is especially suitable for utilizing for the container in which a solid substance is accommodated. In many cases, the cock-type outlets as described in Patent Documents 1 and 2 are good for accommodating a liquid material, but problems may arise when a solid material is accommodated. First, in order to pour out the solid material, it is necessary to make the outlet at a certain size or more, so that the structure of the cock-type outlet for solid matter becomes large. Secondly, the sealing property of the cock-type outlet is easily impaired as the structure of the outlet increases. In this regard, the non-cock type container according to the first aspect does not cause the above problems when the solid substance is accommodated as in the second aspect, and is particularly suitable for the use of accommodating the solid substance.
