Description

[Technical Field]

[0001] The present invention relates to a box body used for a so-called bag-in-box. [Background technology]

[0002] A bag-in-box is a box-shaped device in which a flexible inner container made of polypropylene or other material with high airtightness or watertightness is housed in a rigid box material such as cardboard, and fluids such as liquids or powders inside the flexible container can be dispensed. A box suitable for use as a bag-in-box is described in Patent Document 1, for example. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-70237 Summary of the Invention [Problem to be solved by the invention]

[0004] The box described in Patent Document 1 has a structure in which a single handle is provided in a straight line, which limits how the handle can be held, making it difficult to precisely determine the angle of inclination of the box, hold it at a fixed angle, or swing it from side to side, leaving room for improvement in handling. There is also room for improvement in terms of durability.

[0005] In view of the above problems, the present invention aims to provide a strong box that can further improve the handling performance of an inner container, a sheet for forming the same, and a method for using the same. [Means for solving the problem]

[0006] The present invention, which solves the above-mentioned problems, is a box capable of storing an internal container containing a fluid therein, comprising a box body and a gripping portion to be gripped by a user, wherein the box body has an opening surface on which an opening for attaching and holding the internal container is provided, and an adjacent surface adjacent to the opening surface, and the gripping portion is provided on the adjacent surface and has a first gripping portion and a second gripping portion that are at least partially detachable from the adjacent surface, and is provided in parallel with the first gripping portion and the second gripping portion, or a box that contains an internal container inside the box body. In this way, the configuration in which the gripping portions 11 are arranged side by side and can be partially separated from the adjacent surface allows the user to hold the side by side gripping the gripping portions 11 with the right and left hands, or to insert one hand between them, improving handling properties, and further increasing strength by dispersing the gripping portions.Furthermore, the box body described above is preferably formed from a single sheet.

[0007] Furthermore, the method of using the box described above includes a gripping and pulling out step of lifting the grip portion from the adjacent surface, thereby achieving both ease of storage when not in use and ease of handling when in use. [Effects of the Invention]

[0008] The present invention, which solves the above problems, can provide a box body or box having high strength that can further improve the handling performance of the inner container, a sheet for forming the same, and a method for using the same. [Brief explanation of the drawings]

[0010] Hereinafter, boxes according to various embodiments of the present invention will be described in detail with reference to the drawings. The description will be made in the order of the configuration of the embodiments, the method of implementation, and other examples. The embodiments shown below are examples of the present invention, and the present invention is not limited to the following embodiments. It is also possible to combine some of the configurations of the modified examples. Furthermore, the word "approximately" in the application documents is a concept that means that the shape that follows is chamfered or rounded, and that the elements that make up the shape are deformed or changed in length within a range that does not impede the purpose of the configuration.

[0011] <<Embodiment>> The present invention is a box 1 that can store an internal container 2 containing a fluid therein, and that comprises a box body 10 and a gripping portion 11 that is gripped by a user, wherein the box body 10 has an opening surface 101 that has an opening 12 for attaching the internal container 2 to a predetermined position, and an adjacent surface 102 that is adjacent to the opening surface 101, and the gripping portion 11 is provided on the adjacent surface 102 and has a first gripping portion 111 and a second gripping portion 112 that are at least partially detachable from the adjacent surface, and is arranged in parallel with the first gripping portion 111 and the second gripping portion 112. The present invention also provides a box 1 capable of storing an internal container 2 containing a fluid therein, the internal container 2 having a discharge port 21 for discharging the fluid, the box 1 having an opening surface 101 provided with an opening 12 for mounting and holding the internal container 2, the opening 12 being provided inside the box 1 relative to the opening surface 101, and having a reinforcing member R for reinforcing the mounting portion of the internal container 2, or a box that houses the internal container inside the box. The above-mentioned box is preferably formed from a single sheet. The opening 12 has an opening 120 that connects the inside and outside of the box 1, and locking portions (127, 128) at its edges that lock the discharge port, and these locking portions are provided so that they overlap the surfaces of the material that forms the box 1.

[0012] As shown in Figures 1 to 3, the box 1 has a pillar-shaped box body 10, a gripping portion 11 for the user to grip, an opening 12 for attaching and holding a part of the inner container 2 and for discharging the liquid in the inner container 2 to the outside, a relative closing portion 13 for closing the surface opposite the opening 12, and a finger insertion portion 14 for the user to carry. Here, Figure 3 is a six-sided view of the box body 1, with Figure 3(a) being a plan view showing the adjacent surface 102, Figure 3(b) being a front view showing the side surface 105, Figure 3(c) being a bottom view showing the adjacent opposing surface 104, Figure 3(d) being a right side view showing the opening opposing surface 103, and Figure 3(e) being a left side view showing the opening surface 101.

[0013] The inner container 2 has a soft inner container body 20 that stores a fluid such as a liquid or powder inside, and an outlet 21 that connects the inside and outside of the inner container body 20 and has enough rigidity to not be deformed by a human gripping force.

[0014] The box body 10 is formed in a substantially rectangular parallelepiped shape and has an opening surface 101 in which the opening 12 is provided, an adjacent surface 102 provided adjacent to the opening surface 101, an opening-facing surface 103 facing the opening surface 101, an adjacent-facing surface 104 facing the adjacent surface 102, and a side surface 105 connecting the adjacent surface 102 and the adjacent surface 104. In addition, an overlapping surface 106 having substantially the same shape as the adjacent surface 102 is provided at a position that contacts the underside of the adjacent surface 102. In the embodiment, the adjacent surface 102 is provided on the top surface, but it may be provided on any surface adjacent to the opening surface 101. Here, the box body 10 has a substantially rectangular parallelepiped shape, but is provided so that the longitudinal direction is parallel to the opening axis direction of the opening 12. On the other hand, the box body 10 may be in other columnar shapes such as a hexagonal column or a cylinder.

[0015] The gripping portion 11 has a first gripping portion 111 and a second gripping portion 112, which are generally rectangular and arranged in parallel on the adjacent surface 102, a main gripping portion 113 that is connected to the first gripping portion 111 and the second gripping portion 112 and is arranged to be wider than them, a gripping end portion 114 that connects to the surface of the box body 10, and a cutout portion 115 that makes it easy to lift the gripping portion 11. These are provided by providing cutting lines or cutting out parts along the boundaries of the components on the adjacent surface 102 and on parts of the opening surface 101 and the opening opposing surface 103.

[0016] The opening 12 is a member that forms the opening surface 101 and holds the discharge port 21 so as to be exposed. The opening 12 has an opening 120 that passes through the inside and outside of the box body 1 to expose the discharge port 21, an opening flap 121 that connects with the adjacent opposing surface 104, an overlapping flap 122 that extends from the opening flap 121, and an overlapping extension portion 123 that extends from the overlapping flap 122. The opening 12 also has a side flap 124 that connects with the side surface 105, and a forward-extending flap 125 that connects with the adjacent opposing surface 104. The forward-extending flap 125 has an insertion portion 126 that is inserted between other flaps to secure it in place. The opening flap 121 and the overlapping flap 122 each have an outer locking portion 127 and an inner locking portion 128 that lock the discharge outlet at a predetermined position, and support pieces 129 provided on the inside of these locking portions are arranged so that they can be pushed inside the box body 10.

[0017] The relative closing portion 13 is a portion for closing the opening relative surface 103, and has a relative opening flap 131 that connects to the adjacent relative surface 104, relative side flaps 132 that connect to the side surfaces 105, and a rearward extending flap 133 that connects to the opening relative surface 103, and the rearward extending flap 133 has a relative insert portion 134 that is inserted between other flaps and fixed.

[0018] Finger insertion section 14 is a portion provided on side surface 105, and is provided so that a hole is formed when finger insertion section 14 is pressed into it. Finger insertion section 14 has finger insertion section main body 140 that is actually pressed into, and finger crease line 141 that connects finger insertion section main body 140 and side surface 105.

[0019] Inner container body 20 is a flexible container made of soft plastic such as polypropylene or polyethylene, and is at least watertight. It is filled with a fluid such as liquid or powder. This fluid is expected to be, for example, a herbicide, fertilizer, drinking water, etc., and in this embodiment, it is a herbicide. Furthermore, the volume of inner container body 20 when filled is preferably about 75% to 90% of the volume of box body 10, and outer locking portion 127 and finger insertion portion 14 can be folded inward from the outside of box body 10.

[0020] The discharge outlet 21 has a cylindrical discharge outlet body 210 that communicates with the inner container body 20, and a plurality of fixing plates 22 that are provided so as to protrude outward in the cross-sectional direction from the outer peripheral surface of the discharge outlet body 210. In this embodiment, the fixing plates 22 are a front fixing plate 221, a middle fixing plate 222, and a rear fixing plate 223 that are aligned at intervals from the side closest to the open end face of the discharge outlet body.

[0021] Each surface included in the box body 10 is formed in a substantially rectangular shape. The opening surface 101 includes each component of the opening 12, and the opening 12 as a whole is capable of supporting the discharge port 21 while closing the opening surface 101. The adjacent surface 102 includes at least a part of the gripping portion 11, and the direction in which the opening 120 opens (hereinafter referred to as the opening axis) is the longitudinal direction, thereby increasing the capacity of the inner container 2 while narrowing its width, thereby improving handling performance. In addition, the opening-facing surface 103 includes each component of the relative closing portion 13.

[0022] The overlapping surface 106 is provided so that its width in the short direction is approximately the same as the width of the adjacent surface 102 in the short direction, and its width in the long direction is a rectangle that is shorter than the width of the adjacent surface 102 in the long direction. As a result, the short side of the overlapping surface 106 becomes a separating side 106A that is provided away from the opening surface 101, and enables the gripping portion 11 to operate as described below. In the embodiment, the ends of the adjacent sides of the side surface 105 are connected to the separating side 106A via an inclined side 106B, thereby shortening the distance between the separating sides 106A. In the embodiment, the overlapping surface 106 is joined to the adjacent surface 102 by, for example, an adhesive in an area other than the area where the gripping portion 11 is provided, to form a cylinder.

[0023] The first gripping portion 111 and the second gripping portion 112 are provided in parallel on the opening surface 101 side of the adjacent surface 102, and are each provided separable from the adjacent surface 102 to an extent that at least a finger can be hooked thereon. Furthermore, each gripping end portion 114 extends to the opening surface 101 (forward-extending flap 125), and the other end portion is connected to the main gripping portion 113 via a branch portion 11A. Here, "parallel" is a concept that represents that the axes of the constituent elements are aligned. In the embodiment, the longitudinal axis of the first gripping portion 111 and the longitudinal axis of the second gripping portion 112 are aligned toward the opening surface 101. In the embodiment, each gripping portion is substantially rectangular, and the axes (longitudinal direction) of the elements are parallel to the opening axis, thereby allowing the surface of the gripping end portion 114 to move in a direction parallel to the opening axis, thereby improving strength and operability.

[0024] The main gripping portion 113 is a generally rectangular portion extending parallel to the opening axis on the opening-facing surface 103 side of the adjacent surface 102, and at least a portion thereof is provided separably to a height that allows a finger to be placed over it. A gripping end portion 114 of the main gripping portion 113 extends to the opening-facing surface 103 (rear-extending flap 133), and the other end portion of the main gripping portion 113 is provided wider than at least the first gripping portion 111 and the second gripping portion 112 and is connected to them via the branch portion 11A. In addition, in this embodiment, the main gripping portion 113 is configured so that its width is narrowest at the center in the longitudinal direction and gradually increases toward the ends, thereby enabling the user's gripping position to be guided to the center of the main gripping portion 113.

[0025] Branch portion 11A is a portion that connects main grip portion 113 with first grip portion 111 and second grip portion 112. In the embodiment, branch portion 11A branches into two from wide main grip portion 113, and first grip portion 111 and second grip portion 112 are branched so that they are located closer to side surface 105 than the side edge of main grip portion 113 in a plan view, which makes it easier to rotate the grip portion around the opening axis than in Patent Document 1. In addition, a crease that allows a valley fold is provided at the boundary position with main grip portion 113, making main grip portion 113 easier to hold. Branch portion 11A includes side 11B that is approximately parallel to opening surface 101, and the user can grip grip portion 11 by placing his / her fingers on this side, making it easier to hold and enabling stable operation.

[0026] In this embodiment, the first gripping portion 111, the second gripping portion 112, and the branching portion 11A are arranged to form a U-shaped portion in a plan view (hereinafter simply referred to as the U-shaped portion), and the smooth, continuous edges of the U-shaped portion enhance its strength. The U-shaped portion is arranged to occupy approximately 1 / 5 to 1 / 3 of the entire length of the adjacent surface 102, allowing the main gripping portion 113 to be stably held while being gripped.

[0027] The spacing between the protrusions of the U-shaped portion or the distance between the first gripping portion 111 and the second gripping portion 112 is set to be at least larger than the width of the discharge port 21, and preferably approximately the same as or slightly larger than the width of the outer locking portion 127, making it easier to grip the portion therebetween. Furthermore, the discharge port 21 is positioned between the first gripping portion 111 and the second gripping portion 112 in a plan view on the opening surface 101, making it easier to aim the discharge. Preferably, the discharge port 21 is positioned on a line that is parallel to and equidistant from the first gripping portion 111 and the second gripping portion 112 on the opening surface 101, making it easier to adjust and aim.

[0028] The gripping end 114 is integrally connected to the ends of the first gripping portion 111, the second gripping portion 112, and the main gripping portion 113, and is a portion provided on the opening surface 101 or the opposing surface 103 of the opening, and is capable of lifting the entire gripping portion 11 by deforming as shown in Figures 5 and 6. Note that, for the sake of simplicity, the side flaps 124 and the opposing side flaps 132 are omitted in Figures 5 and 6.

[0029] 2 and 5, at least one side of the grip end 114 is a boundary side 114A that includes the boundary between the surfaces. The boundary side 114B opposite to the boundary side 114A is provided so that it can be folded toward the inside of the box body 10, and an arc-shaped notch is provided at the end to facilitate folding. In this embodiment, the grip end 114 is a rectangular member that is wide in the width direction.

[0030] By bending the boundary-facing side 114B from the state shown in Fig. 5(a) toward the inside of the box body 10, the gripping end 114 is tilted inward as shown in Fig. 5(b), and the entire gripping portion 11 is raised upward by the amount of tilt. At this time, the separating side 106A and the gripping end 114 interfere with each other, thereby controlling the maximum angle of tilt. Furthermore, part of the boundary side 114A interferes with the notch or back surface of the adjacent surface 102, thereby dispersing the tensile force applied from the gripping portion 11 to the opening surface 101 and the opening-facing side 103, improving durability and gripping performance.

[0031] Cutout 115 is a cutout portion provided to include the side edge of main gripping portion 113, and creates a step between adjacent surface 102 and overlapping surface 106. This exposes the side edge of gripping portion 11 on adjacent surface 102, making it easier to lift. Cutout 115 is provided near the longitudinal center of adjacent surface 102, so that when the main gripping portion is lifted, force is applied equally to each of gripping ends 114.

[0032] As shown in Fig. 7, the box of this embodiment can be held by inserting a finger into the downwardly convex part of the U-shaped portion. By moving the hand holding the U-shaped portion, it becomes easy to adjust the inclination of the opening 12, hold it at a certain angle, and swing it left and right, improving operability. Furthermore, durability is improved because the force is distributed between the first grip portion 111 and the second grip portion 112.

[0033] The opening 12 will be described below with reference to FIGS. The opening 120 is provided on an opening flap 121 , and other flaps are provided to surround the opening 120 .

[0034] The opening flap 121 is connected to the adjacent opposing surface 104, and its width is approximately equal to that of the adjacent opposing surface 104, and its height is smaller than that of the side surface 105, so that the entire flap can be inserted into the box body 10 when folded. In this embodiment, the opening flap 121 is provided to have a generally concave shape, and is foldably connected to the overlapping flap 122 via a connecting edge 121A located at the bottom of the upper edge thereof.

[0035] The overlapping flap 122 is foldably connected to the opening flap 121 and reinforces the opening flap as a reinforcing member R. More specifically, the lower edge is formed in a convex shape corresponding to the concave shape of the opening flap 121, and the end of the convex shape is connected to the opening flap 121 as a connecting edge 121A. This reduces loss during sheet creation and maintains strength. The width of the overlapping flap 122 is approximately the same as the width of the opening flap 121, and the height of the overlapping flap 122 (the distance from the connecting edge 121A to the upper edge) is approximately the same as the distance from the connecting edge 121A to the boundary between the opening flap 121 and the adjacent opposing surface 104, so that the entire overlapping flap 122 overlaps with the opening flap 121. The opening flap 121 and the overlapping flap 122 are provided with perforations in the area other than the connecting edge 121A so as to be separable, and are foldable around the connecting edge 121A.

[0036] The overlapping extension 123 is a generally rectangular portion extending from the upper edge of the overlapping flap 122. Its width is roughly the same as that of the overlapping flap 122, and its extension length is approximately 1 to 3 cm. When folded during assembly, the overlapping extension 123 abuts entirely against the adjacent mating surface 104, and acts as a reinforcing member R that holds the overlapping flap 122 in place to prevent it from penetrating inside.

[0037] The side flaps 124 are connected to the side surface 105 and are provided symmetrically. In this embodiment, the shape is such that a rectangle (hereinafter, rectangular portion) is connected to the upper base of a right-angled trapezoid (hereinafter, trapezoid portion). The lower base of the trapezoid portion is shared with the side surface 105, and the side perpendicular to the lower base is disposed along the adjacent surface 102. The height of the rectangular portion is set to be approximately the same as or slightly shorter than the difference between the length of the lower base and the distance from the connecting edge 121A to the boundary between the opening flap 121 and the adjacent opposing surface 104, thereby preventing interference with the support piece 129 and increasing strength by allowing the opening flap 121 and the side flaps 124 to cover almost the entire opening surface 101. In addition, the side flaps 124 are provided with a slight gap from the adjacent opposing surface 104, allowing the side flaps 124 to move in the opening axis direction, preventing the operation of the gripping end portion 114 from being hindered. The oblique side of the trapezoidal portion is inclined so as not to overlap with the outer engaging portion 127, but the entire portion overlaps with the opening flap 121 and is arranged so as to partially interfere with the overlapping extension portion 123 at the lower end, thereby increasing the strength of the opening 12.

[0038] The forward-extending flap 125 is a portion extending from the adjacent surface 102 and covers at least the entire rectangular portion of the side flap 124, but is formed to have a shape and height such that it does not overlap with the oblique side of the side flap 124 or the outer engaging portion 127. The forward-extending flap 125 is also formed so that at least a portion of its edge overlaps with a portion of the opening flap 121. In this embodiment, the forward-extending flap 125 is a substantially rectangular surface, has approximately the same height as the rectangular portion, and is approximately the same length as the shared side of the adjacent surface 102, but is shaped to taper slightly downward. The upper end of this portion also includes a gripping end 114. Furthermore, an insertion portion 126 is integrally formed at the lower end of this portion so as to protrude from the center in the width direction.

[0039] The insertion portion 126 includes a gap-covering portion that covers the gap between the rectangular portion and the outer locking portion 127, and a protruding portion that protrudes from the side of the gap-covering portion. The width of the gap-covering portion is approximately the same as or slightly shorter than the length of the connecting edge 121A, and its height is approximately the same as or slightly shorter than the distance from the locking connecting edge 12A to the connecting edge 121A. This allows the insertion portion 126 to be inserted into the recess of the opening flap 121 while preventing interference with the outer locking portion 127. The protruding portion is provided with a gap from the forward extending flap 125 and is independently bendable due to the flexibility of the material. The protruding length of the protruding portion is preferably approximately 2 cm to 3 cm, but any shape is acceptable as long as it overlaps with the oblique side of the side flap. This allows it to be inserted and supported in the gap formed between the opening flap 121 and the side flap 124 or the oblique side of the trapezoidal portion.

[0040] As described above, opening flap 121 is held by alternately sandwiching it between forward extending flap 125 and insertion portion 126, so that opening flap 121 does not easily deform even when force is applied from inside or outside opening flap 121. In addition, overlapping flap 122 that overlaps opening flap 121 is provided to increase the strength around the opening, and overlapping extending portion 123 makes opening flap 121 less likely to sag inward.

[0041] The outer locking portion 127 is a recessed portion provided at approximately the center in the width direction of the opening flap 121 as part of the locking portion, which locks the discharge port 21 at the edge of the opening 120, and is disposed on the opening surface 101. In addition, the outer locking portion 127 includes an adjacent mating surface 104 as part thereof, which makes it easy to separate.

[0042] The inner locking portion 128 is provided adjacent to the rear surface of the outer locking portion 127 (inside the box body 10) as a reinforcing member R, and the doubling of the locking portion firmly supports the discharge port 21. The inner locking portion 128 is a recessed portion provided as part of the locking portion at approximately the center of the overlapping flap 122 in the width direction. It locks the discharge outlet 21 at its edge and is positioned so that part of it includes the overlapping extension portion 123. This brings the discharge outlet 21 closer to the bottom surface, lowering the center of gravity and making it easier to aim. The inner locking portion 128 has approximately the same shape as the outer locking portion 127. Preferably, the inner locking portion 128 is positioned symmetrically with the outer locking portion 127 with respect to the connecting edge 121A so that the openings overlap. More preferably, the distance to the connecting edge 121A of the inner locking portion 128 is greater than that of the outer locking portion 127 by at least the thickness of the box body 10, making it easier to insert the support piece 129 inside.

[0043] In the opening flap 121, the support piece 129 is connected to a part of the opening flap 121 via the engaging connection edge 12A which is arranged parallel to the connection edge 121A, and the other part is arranged so as to be detachable from the opening flap 121 along the outer engaging portion 127. Furthermore, support piece 129 is provided with a plurality of folds parallel to locking connection side 12A, and is provided so as to be deformable within a predetermined range. In this embodiment, outer locking portion 127 has two folds, and the fold on the side away from connection side 121A is provided so as to be positioned at the boundary between insertion area 12B and holding area 12C, which will be described later. In the overlapping flap 122, the support piece 129 has a fold and a locking connecting edge at the same position as the above-mentioned support piece 129, and can be separated along the inner locking portion 128, so that the two support pieces 129 operate in conjunction with each other. These support pieces 129 are folded inside the box body 10 relative to the opening surface 101, and their ends abut against the top surface side of the fixed plate 22, thereby acting as a reinforcing body R that reinforces the discharge outlet 21 to prevent it from falling inside the box body 10.

[0044] Before use, opening flap 121 and overlapping flap 122 have perforations along the locking portions. When in use, support piece 129 of each flap is pushed into box body 10, creating opening 120 in the area where support piece 129 was located, with the edge of opening 120 becoming the locking portion. This opening includes insertion region 12B, which is wider than the diameter of spout 21 and allows easy insertion of spout 21, and holding region 12C adjacent to it that holds spout 21. As a result, as shown in the figure, the positions where the lid and opening will be provided during assembly overlap, increasing the strength of the area around opening 120 and the lid.

[0045] The locking connection side 12A is a side of the outer locking portion 127 that is provided at a position parallel to and spaced from the common side between the opening surface 101 and the adjacent mating surface 104. This allows the support piece 129 to be pulled out or pushed in using this as a rotation axis, as shown in FIG. 10. In this embodiment, the outer locking portion 127 maintains its strength by providing a gap of approximately 1 cm to 3 cm from the connection 121A. Note that the locking connection side 12A may be provided so as to be detachable.

[0046] The insertion area 12B includes the locking connection edge 12A on one side at its upper end, and its widthwise length is approximately the same as or slightly shorter than the width of the gap-covering portion, with a double edge to increase the strength around the opening. The surface of the insertion area is sized to include at least the outer diameter of the outlet body 210, allowing for easy insertion. Preferably, this size is approximately the same as or slightly larger than the maximum length of the outlet 21, allowing the outlet 21 to be inserted by holding the fixing plate 22.

[0047] Furthermore, the widthwise length of the holding region 12C is set to be approximately the same as the outer diameter of the outlet body 210, thereby interfering with the fixed plate 22 and restricting movement of the outlet 21 in the opening axial direction. The holding region 12C includes the adjacent mating surface 104 in part, making it easy to peel the support piece 129 from this portion. Furthermore, the height of the holding region 12C is set to be at least greater than half the outer diameter of the outlet body 210, enabling the outlet 21 to be firmly held.

[0048] The insertion region 12B is disposed adjacent to the holding region 12C, and both are disposed at the center in the width direction. The edge of the insertion region 12B is connected to the edge of the holding region 12C via an inclined edge so as to smoothly narrow, allowing the ejection port 21 inserted in the insertion region 12B to be easily moved to the holding region 12C. The insertion region 12B, including this connecting region, is arranged to form a surface that includes at least the circumscribing circle of the ejection port body 210, making the insertion process easier.

[0049] When the box 1 is assembled, an opening of a similar shape is also provided on the overlapping flap 122, and is aligned so as to overlap with the opening on the opening flap 121. The overlapping flap 122 may be provided by providing an additional flap extending therefrom, and the opening provided on this flap may overlap the aforementioned opening.

[0050] FIG. 11(a) is an explanatory perspective view showing the state around the discharge port 21 in use. As shown in FIG. 11( a), the discharge port 21 is held in a position close to the bottom surface in the holding region 12C of the opening 12. In the state shown in FIG. 11( a), the front fixing plate 221 is positioned between the opening flap 121 and the overlapping flap 122, and the front fixing plate 221 interferes with the opening axial direction to hold the position. Additionally, the intermediate fixing plate 222 interferes with the rear surface of the overlapping flap 122 to prevent the discharge port 21 from unintentionally falling off. The alignment of the flaps to sandwich the fixing plate 22 significantly improves the holding performance. Meanwhile, as schematically shown in FIG. 11( b), which shows a cross section taken along the AA direction, the front fixing plate 221 may interfere with the front surface of the opening flap 121 to prevent the inner container 2 from falling into the box body 10. In this case, the intermediate fixing plate 222 is positioned between the opening flap 121 and the overlapping flap 122, and the rear fixing plate 223 interferes with the rear surface of the overlapping flap 122, thereby improving the holding performance.

[0051] 11, the support piece 129 of the inner locking portion 128 is folded inward of the box body 10 at the locking connection side 12A and outward at a fold line that corresponds to the boundary between the insertion area 12B and the holding area 12C. As a result, the end of the support piece 129 is positioned to press against the fixing plate 22, further improving the holding performance, as shown schematically in FIG. 12(a), which shows the cross section at the AA position. Here, because the height of the insertion area 12B is higher than the height of the holding area 12C, the end of the support piece 129 can press against the fixing plate 22 from inside the box body 10, and the holding force can be appropriately applied in the opening axis direction. Furthermore, in this embodiment, the support pieces 129 of the inner locking portions 128, which have a similar shape, overlap with the support pieces 129 of the outer locking portions 127 to press the fixed plate 22, thereby further improving the holding performance.

[0052] The relative closing portion 13 has a structure substantially similar to that of the opening 12, and closes the opening relative surface 103. The opening relative surface 103 is provided to have a structure substantially similar to that of the opening surface 101, with the relative opening flap 131 corresponding to the opening flap 121, the relative side flap 132 corresponding to the side flap 124, the rearward extending flap 133 corresponding to the forward extending flap 125, and the relative insertion portion 134 corresponding to the insertion portion 126, and therefore a description of the portions having similar configurations will be omitted.

[0053] The opposing rectangular portions of the opposing side flaps 132 are different in length, so that the inner container 2 can be held on the surface by pressing the center of the opening opposing surface 103 with a hand. The rearwardly extending flap 133 is a portion extending from the adjacent surface 102, and covers at least the entire rectangular portion of the relative side surface flap 132, but is formed with a shape or height that does not overlap with the oblique side of the relative side surface flap 132. The rearwardly extending flap 133 is formed so that at least a portion of its side forms an inclined edge that overlaps with a portion of the relative opening flap 131. In this embodiment, the rearwardly extending flap 133 is a trapezoidal surface, has approximately the same height as the rectangular portion, has an upper edge (lower base) that is shared with one side of the adjacent surface 102, and has a lower edge (upper base) that is approximately the same length as the connecting side, and the upper and lower bases are connected by symmetrical inclined edges. The upper edge (lower base) of this portion includes a grip end 114. Furthermore, a relative insertion portion 134 is integrally formed at the lower end of this portion so as to protrude from the center in the width direction.

[0054] Finger insertion section 14 is a hole provided in side surface 105, and is a portion into which a finger can be inserted and which can be pushed into box body main body 10. Finger insertion section 14 has finger insertion section main body 140 and finger crease line 141, which is a side connecting finger insertion section main body 140 and side surface 105.

[0055] Finger insertion section main body 140 is shaped like an elongated hole, with its long axis parallel to the height direction, and is located close to opening 12. This is located on the side of side surface 105 that is closer to opening surface 101, allowing for easy storage with opening-facing surface 103 as the bottom, and for easy movement associated with this.

[0056] Finger crease line 141 is a side of finger insertion portion main body 140 that is located close to opening surface 101 and is arranged parallel to opening surface 101. Preferably, the width of finger insertion portion main body 140 is arranged to be approximately the same as or slightly longer than the distance from finger crease line 141 to opening surface 101, so that the inside of finger insertion portion main body 140 abuts against opening 12 as shown in Figure 12(b) which shows the BB cross section, thereby further improving the support performance of discharge outlet 21.

[0057] 《Case manufacturing method》 The box manufacturing method of the present invention will be described in detail below with reference to the drawings. The present invention is implemented by a manufacturer who manufactures boxes. The implementation method described below is an example, and the implementation method is not limited to this, and the order of the steps may be reversed.

[0058] First, in the punching process, the manufacturer punches out sheet material S from a cardboard or plastic sheet along the edge as shown in Fig. 2. Here, sheet material S is configured such that adjacent surface 102, side surface 105, adjacent opposing surface 104, side surface 105, and overlapping surface 106 are connected to each other along the longitudinal direction. On the shorter side of each surface, a forward-extending flap 125 and a rearward-extending flap 133 are connected to adjacent surface 102, an opening flap 121 and an opposing opening flap 131 are connected to adjacent opposing surface 104, and a side flap 124 and an opposing side flap 132 are connected to side surface 105. Next, in FIG. 2, the sheet material S is creased along the folds indicated by the solid lines on the inside, and further perforations (cut lines) are formed along the perforations indicated by the dashed lines.

[0059] Next, in the tube-forming process, the manufacturer glues the front side of the overlapping surface 106 and attaches it so that it overlaps with the back side of the adjacent surface 102 to form a tube. No glue is applied to the area of ​​the adjacent surface 102 where the gripping portion 11 is located, including the cutout portion 115. In addition, the separating edge 106A is provided so as to be separated from the edges on both sides of the adjacent surface 102. Note that glue may be applied to the adjacent surface 102.

[0060] Next, the manufacturer closes the relative closing portion 13 as the opening relative surface closing step. In this step, the manufacturer first folds the relative side flaps 132 inward as shown in FIG. 13(b). Next, as shown in FIG. 4(d), the rearward extending flaps 133 are placed so as to overlap the relative opening flaps 131. At this time, the relative inserting portion 134 is positioned so as to abut against the back surface of the relative opening flaps 131. In addition, at this time, it is preferable that the protruding portion of the relative inserting portion 134 is placed on the back surface of the relative side flaps 132, which increases strength.

[0061] After the manufacturer stores the inner container in the box body 1 with only the opening surface 101 open, the manufacturer closes the opening 12 in the state shown in Fig. 8(a) as the opening closing step. In this step, the manufacturer first rotates the overlapping flap 122 around the connecting edge 121A as an axis, as shown in Fig. 8(b), to bring it into contact with the opening flap 121. At this time, the overlapping extension portion 123 is positioned inside the box body 10. Next, the manufacturer folds the side flaps 124 as shown in Figure 9(a) . In this state, the overlapping extensions 123 are positioned so as to abut the underside of the side flaps 124. Next, the manufacturer places the forward-extending flap 125 on top of the opening flap 121 as shown in Figure 9(b). At this time, the insertion portion 126 is placed on the back surface of the opening flap. In addition, at this time, it is preferable that the protruding portion is placed on the back surface of the opposing side flap 132, so that the insertion portion 126 abuts against multiple surfaces and the opening flap 121 is more firmly clamped.

[0062] Through the above steps, the manufacturer can manufacture box X. When lifting or displaying the box, the manufacturer can easily carry it by placing the opening facing surface 103 as the bottom and inserting fingers into finger insertion portion 14.

[0063] <<Implementation Method>> A method for carrying out the present invention will be described in detail below with reference to Figures 10 to 12. The present invention is carried out by a user who dispenses the fluid in the inner container 2 while holding the box 1. The method for carrying out the present invention is an example, and the method for carrying out the present invention is not limited to this, and the order of the steps may be reversed.

[0064] First, as the locking portion operation step, the user separates the support pieces 129 from the adjacent surface 102 along the outer locking portions 127 and inner locking portions 128, causing them to protrude outward, as shown in Figure 10(a). At this time, the support pieces 129 are arranged so that they overlap. Next, the user folds the overlapped support pieces 129 along the fold lines and inserts them into the inside of the box body 10 in this state.

[0065] Next, as the outlet pulling-out step, the user pulls out the outlet 21 as shown in Figure 11. The user finds the outlet 21 by inserting their finger into the insertion region 12B, then grasps the outlet 21 and pulls it out of the insertion region 12B. The user then inserts the outlet 21 into the holding region 12C so that the fixing plate 22 is positioned between the outer locking portion 127 and the inner locking portion 128 (reinforcement R). At this time, the edges of the insertion region 12B and the holding region 12C are connected at an angle, which makes it easy to fix the outlet 21 to the holding region 12C. The outlet 21 is supported by abutting against the reinforcement R and is firmly held in a predetermined position in the opening 12.

[0066] Next, as a discharge outlet pressing step, the user fixes the support pieces 129 of the outer locking portion 127 and the support pieces 129 of the inner locking portion 128 by pressing them against the fixed plate 22 as shown in FIGS. 11 and 12(a). This allows the support pieces 129 to be used as reinforcing members R that do not get in the way even without being removed and that hold the discharge port 21 so that it does not fall. In the embodiment, the support pieces 129 are pressed against the fixed plate 22 so that they overlap, thereby further improving the holding performance.

[0067] Next, as a gripping / pulling step, the user lifts up the grip 11 on the adjacent surface 102. That is, by lifting up the main grip 113 exposed in the cutout 115, the user can form a gap between the grip 11 and the box body 10 while maintaining the shape of the box 1, as shown in Figure 3. At this time, the grip end 114 is inclined, and the box body 10 and the grip 11 are smoothly connected, thereby increasing the strength of the grip 11.

[0068] Finally, the user supports the grip portion 11 with both hands and dispenses the fluid, as shown in Fig. 7. That is, the user can support the weight of the box by holding the main grip portion 113 with one hand, and can also insert the other hand into the U-shaped portion to adjust the direction of the discharge port 21, thereby further improving usability.

[0069] First Change Example A first modified example of the present invention is shown in Fig. 14. In the modified example shown in Fig. 14, the gripping end 114 on the opening surface 101 side is connected to the main gripping part 113, and the gripping end 114 on the opening opposing surface 103 side is connected to the first gripping part 111 and the second gripping part 112. In this way, by holding the main grip portion 113 as an axis and operating the U-shaped portion, the moment from the opening 12 can be lengthened, and the angle of the discharge port 21 can be adjusted more precisely. In this modification, the gripping ends 114 of the first gripping portion 111 and the second gripping portion 112 are parallelograms, and are arranged in parallel such that the spacing between their axes widens toward the gripping ends 114. This makes it easy for the user to insert their hand into the separated U-shaped portion. On the other hand, the spacing between the shafts may be narrowed to increase strength.

[0070] Second modification example A second modified example of the present invention is shown in Fig. 15. In the modified example shown in Fig. 15, a first gripping portion 111 and a second gripping portion 112 are independent of each other and are separably provided on the adjacent surface 102 parallel to the opening axis direction. The configuration of the gripping end portions 114 on both ends is the same as in the embodiment. This allows various parts of each grip to be supported, broadening the range of uses. Also, the grips are symmetrical, making it easy to operate for both right-handed and left-handed people.

[0071] Third modification example A third modified example of the present invention is shown in Fig. 16. As shown, a tear line 15 for disassembling the box body 10 may be provided. The tear line 15 extends perpendicular to the boundary line between the side surface 105 and the adjacent surface 102, and extends from the side surface 105 through the adjacent opposing surface 104 to the boundary between the opposing side surface 105 and the adjacent surface 102. The tear line 15 is also provided between the cutout portion 115 and the finger insertion portion 14. This allows the box body 10 to be rotated about the adjacent surface 102 to expose the opening, making it easy to separate the inner container 2 from the box body 10 for easy sorting.

[0072] Furthermore, the grip portion 11 is provided parallel to the opening direction of the opening 12, which makes it easy to adjust the angle and to aim the discharge.

[0073] Furthermore, the opening of the opening portion 12 is arranged between the axis of the first gripping portion 111 and the axis of the second gripping portion 112 in a plan view, which makes it easier to aim the discharge. It is even more preferable that this opening is arranged on an extension line of the two gripping ends 114 on the opening surface 101.

[0074] Furthermore, the ends of the first gripping portion 111 and the second gripping portion 112 are connected at the opening surface 101, which prevents shear forces from acting at the connection portion compared to when they are connected to the adjacent surface 102, thereby further increasing strength.

[0075] In addition, the gripping portion 11 has a main gripping portion 113, and the first gripping portion 111 and the second gripping portion 112 are branched off from the main gripping portion 113, so that the box body 1 can be easily operated by placing a finger on the branched portion 11A.

[0076] Furthermore, the branched portion 11A branching off from the main gripping portion 113 is located closer to the opening 12 than the center of the adjacent surface 102, making it easier to adjust the center of gravity by placing a finger near the opening 12, and allowing for intuitive discharge operations.

[0077] In addition, the box body 10 has an opening opposing surface 103 opposite to the opening surface 101, and the end of the main gripping portion 113 is connected to the opening opposing surface 103, making it possible to easily grip the main gripping portion 113.

[0078] In addition, an overlapping surface 106 is provided on the back surface of the adjacent surface 102, and the side of the overlapping surface 106 facing the opening surface 101 has at least a portion of a separation edge 106A that is spaced apart from the opening surface 101, and the end of the gripping portion 11 is located on the opening surface 101, is provided on a forward extending flap 125 extending from the adjacent surface 102, and is arranged to be slidable in the direction of the separation edge 106A.

[0079] The locking portion has an outer locking portion 127 that locks the discharge outlet 21 on the outside, and an inner locking portion 128 that locks the discharge outlet 21 on the inside, the outer locking portion 127 being provided on the opening flap 121, and the inner locking portion 128 being provided on the overlapping flap 122, and the opening flap 121 and the overlapping flap 122 being folded and overlapped around the locking connection edge 12A as an axis, thereby forming an overlapping locking portion that achieves both ease of box manufacturing and strength.

[0080] In addition, the opening 12 further includes an overlapping extension portion 123 that extends from the overlapping flap 122 and abuts the inner surface of the box body 1, thereby forming a truss in cross section and preventing the overlapping flap 122 from falling inside the box body 10.

[0081] In addition, the locking portion has an insertion area 12B whose maximum width is larger than the discharge outlet 21, and a holding area 12C that holds the discharge outlet 21, and the edges of the insertion area 12B and the holding area 12C are connected via inclined edges, which makes it easy to pull out the discharge outlet 21 and lock and hold it in the holding area 12C.

[0082] Furthermore, by making the periphery of the opening 120 include the edge of the box body 1 (the boundary between surfaces, for example, the boundary between the opening surface 101 and the adjacent opposing surface 104), the load in the direction of gravity on the edge of the box body 1 is suppressed, making it easier to peel off the support piece 129.

[0083] Furthermore, the opening 12 further has a support piece 129 that presses and supports the discharge port 21 toward the outside of the box body, thereby making it difficult for the inner container 2 to fall into the box body 1 . Furthermore, support piece 129 is cut out along the locking portion when in use and is provided so that it can be folded inside the box, thereby improving the functionality of the opening. Also, by connecting support piece 129 to the locking portion using locking connection edge 12A as a fold line, support piece 129 does not need to be disposed of as separate waste and can be used more effectively.
