[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 stores an internal container 2 containing a fluid therein, and includes a box body 10, an opening surface 101 thereof, and an adjacent surface 102 adjacent to the opening surface 101, the opening surface 101 having an opening 12 that passes through to the interior, and the adjacent surface 102 having a gripping portion 11 that is held by a user, the gripping portion 11 having a plurality of finger loops 110 on the inside of the hole for the user to loop their fingers around, the finger loops 110 including the adjacent surface 102 on at least a portion of the periphery thereof, or a box X in which the internal container 2 is stored in the box body 1 in this manner. By forming a plurality of finger hooks 110 as holes that partially include the adjacent surface 102, it is possible for the user to easily hold the device in various ways and to easily orient the opening 12 at an appropriate angle.

[0012] As shown in Figures 1 to 3, the box 1 has a pillar-shaped box body 10, a gripping portion 11 for a 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, and a relative closing portion 13 for closing the surface opposite the opening 12. 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-facing surface 104. In addition, an overlapping surface 106 having substantially the same shape as the adjacent surface 102 is provided at a position corresponding to the lower surface of the adjacent surface 102. Here, the box body 10 has a substantially rectangular parallelepiped shape, but the length in the direction parallel to the axial direction in which the opening 12 is provided is the longitudinal direction. On the other hand, the box body 10 may be in the shape of a hexagonal pillar, a cylinder, or any other columnar shape.

[0015] In this embodiment, the grip portion 11 has a plurality of finger hooks 110 that can be gripped by a user with their fingers. These finger hooks 110 are provided so as to be able to transition between a use state in which the user can grip the grip with their fingers and an unused state in which the grip cannot be gripped. Each finger hook 110 has a hole 111 through which the user can insert their finger in the use state, a blocking portion 112 that closes the hole 111 in the unused state, a connecting edge 113 that connects the edge of the hole 111 to the blocking portion 112, and a lifting portion 114 that is adjacent to the blocking portion 112 in the unused state and serves as a starting point for gripping the blocking portion 112. The finger hook 110 includes a hole 111 provided on the adjacent surface 102 and is disposed so that at least a portion of the periphery of the hole 111 includes the adjacent surface 102 .

[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 to the bottom surface of the box body main body 10, a side flap 122 that connects to a surface that stands upright against the bottom surface of the box body main body 10, and a forward-extending flap 123 that connects to the top surface of the box body main body 10. The forward-extending flap 123 has an insertion portion 124 that is inserted between other flaps to secure it in place. The opening flap 121 has a locking portion 125 that locks the discharge port 21 at a predetermined position, and a locking piece 126 provided on the inside of this locking portion 125 is configured to be inserted into the inside of the box body main 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 bottom surface portion of the box body 10, relative side flaps 132 that respectively connect to surfaces that stand upright against the bottom surface of the box body 10, and a rearward extending flap 133 that connects to the top surface of the box body 10, and the rearward extending flap 133 has a relative insertion portion 134 that is inserted between other flaps and fixed in place.

[0018] As shown in Fig. 3, 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 a 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 locking portion 125 and finger insertion portion 14 can be folded inward from the outside of box body 10.

[0019] 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, a middle fixing plate, and a rear fixing plate that are aligned at intervals from the side closest to the open end face of the discharge outlet body (not shown).

[0020] 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 entire opening 12 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 12 opens (hereinafter referred to as the direction of the opening axis) is the longitudinal direction, increasing the capacity of the inner container 2 while narrowing its width, thereby improving handling performance. The opening opposing surface 103 includes each component of the opposing closing portion 13.

[0021] The overlapping surface 106 is provided to be approximately the same size as or slightly smaller than the adjacent surface 102, so that it overlaps with the back surface of the adjacent surface 102. In the embodiment, the overlapping surface 106 is provided with an overlapping hole 111A that overlaps with the hole 111 and at least a portion of which is out of position with the lifting portion 114. 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 portion where the overlapping hole 111A is provided, thereby forming the box body 1.

[0022] In this embodiment, four finger hooks 110 are provided in a line on the adjacent surface 102. The finger hooks 110 are arranged at predetermined intervals so that they are all equally spaced from the corners of the approximately rectangular adjacent surface 102, thereby increasing the strength of the adjacent surface 102 and increasing the degree of freedom in the gripping position. In addition, a pair of finger hooks 110 having opposing connecting sides 113 is referred to as a counter finger hook 110A. The counter finger hooks 110A are line-symmetrical, with one provided on the opening 12 side and one provided on the counter closing portion 13 side.

[0023] The holes 111 are elongated holes provided in plurality on the adjacent surface 102. More specifically, the holes 111 are provided in the shape of a rectangle with rounded corners, and the longitudinal direction of the holes 111 is parallel to the axial direction of the discharge port 21 and also parallel to the longitudinal direction of the adjacent surface 102, making it easy for the user to lift and grip the holes from above.

[0024] Closure portion 112 is made of the same material as box body 10 and is provided in approximately the same shape as the edge of hole 111. When not in use, closure portion 112 is located on the same plane as adjacent surface 102, and when in use, it rotates around connecting edge 113 as an axis and is folded to the outside or inside of hole 111. This makes it easier to distribute the shape of the container when not in use as a simple box. More specifically, when not in use, the closing portion 112 is connected to the adjacent surface 102 via a cut line at the edge other than the connecting edge 113 and the lifting portion 114, thereby preventing the closing portion 112 from being unintentionally put into use.

[0025] The connecting edge 113 is a straight edge that connects a part of the hole 111 and a part of the blocking portion 112. The connecting edge 113 is provided so as to face each other in the finger hook portion 110A. In other words, it is provided on the side of the hole 111 that is closest to the paired finger hook portion 110. In further other words, it is provided on the side of the hole 111 that is closer to the center of the adjacent surface 102. This allows the connecting edges 113 to be multiplexed, thereby increasing strength. Here, in the short-side direction, the distance between the connecting sides 113 of the finger hook portion 110A is preferably longer than the short-side length of the hole 111, which allows one blocking portion 112 to be folded under the other blocking portion 112 as shown in Fig. 5(a), thereby increasing strength. Also, as shown in Fig. 6(a) and Fig. 6(b), it is possible to make the cross section triangular, and by making the grip portion three-dimensional, it becomes easier to hold.

[0026] In this embodiment, the connecting edge 113 is a fold line, but as an alternative, the connecting edge 113 may be a cut line. This allows the user to separate the closing portion 112 when using the box, making it easier to grip, especially for users with small palms. Figure 5(b) is a schematic diagram showing how the box 1 is gripped after the closing portion 112 has been cut off at the connecting edge 113.

[0027] The lifting portion 114 is a portion provided as a starting point for lifting the closure portion 112 when it is not in use. In this embodiment, the lifting portion 114 is provided as a step between the adjacent surface 102 and the overlapping surface 106, and acts as a starting point for gripping the side of the closure portion 112. The lifting portion 114 is cut out adjacent to the side of the hole 111 opposite the connecting side 113, thereby reducing the force required for rotation about the connecting side 113 as an axis.

[0028] When providing a lifting portion 114 assuming that the box body 10 will be pushed inside as shown in Figure 6(b), it is preferable to not form the lifting portion 114 so that the entire edge of the hole 111 is doubled, and to provide the hole 111 and the overlapping hole 111A so that their sizes and positions match.

[0029] Furthermore, by making the width of the blocking portion 112 shorter than half the distance between the connecting edges 113 of the finger hook portions 110A as shown in Figure 6(c), a gap is not created between the adjacent surface 102 and the blocking portion 112 when folded, thereby preventing deformation of the blocking portion 112 during use and further increasing its strength.

[0030] In this embodiment, a finger hook 110 is also provided on the adjacent opposing surface 104. The position, size, and range of the finger hook 110 on the adjacent opposing surface 104 are preferably the same as those on the adjacent surface 102 and symmetrical with respect to a plane parallel to the adjacent surface 102. This allows the herbicide to be held with both hands, as shown in FIG. 5. By placing one hand in the finger hook 110A on the opening 12 side, the tilt of the discharge port 21 can be easily adjusted. Two finger hooks 110A are provided parallel to each side. Referring to FIG. 5(b), an example of how to hold the box 1 is shown. The user can hold the box body 10 at two points close to the diagonal line by grasping the finger hook 110A on one side 105 closer to the opening 12 and the finger hook 110A on the other side closer to the relative closing portion 13. This allows the user to easily tilt or rotate the box body 10. Furthermore, since two finger hooks 110A are arranged in parallel on each surface, the above holding manner can be adopted by either right-handed or left-handed people by changing which finger hook 110A to hold. In this respect, the lifting portion 114 of the finger hook portion 110 is simply a hole through which the user can insert a fingertip, and the user uses this hole to push or pull out the closing portion 112.

[0031] The opening 12 will be described below with reference to FIGS. The opening 120 is provided on an opening flap 121, and the other flaps are provided so as to surround the opening 120. Note that the grip portion 11 is omitted in these figures.

[0032] The opening flap 121 is connected to the bottom surface (side surface 105), its width is approximately equal to the width of the side surface 105, and its height is lower than the height of the surface (adjacent surface 102) that stands upright against the bottom surface, so that the entire opening flap can be inserted into the inside of the box body 10 when folded. In this embodiment, the opening flap 121 is provided to have a concave shape as a whole, with a concave side 121A located at the bottom of the upper edge thereof.

[0033] The side flaps 122 are portions that connect to the surfaces (adjacent surfaces 102, opposing adjacent surfaces 104) that stand up from the bottom surface, and are provided symmetrically. In this embodiment, the shape is a rectangle (hereinafter, rectangular portion) connected to the upper base of a right-angled trapezoid (hereinafter, trapezoidal portion). The trapezoidal portion shares one side with the side of the standing surface, and the side perpendicular to the bottom base is arranged so as to follow the top surface (side surface 105). 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 bottom base and the distance from the recessed side 121A to the boundary between the opening flap 121 and the bottom surface (side surface 105), thereby preventing interference with the locking piece 126 described below, and the opening flap 121 and the side flaps 122 cover approximately the entire opening surface 101, thereby increasing strength.

[0034] The forward-extending flap 123 is a portion extending from the top surface (side surface 105) and covers at least the entire rectangular portion of the side surface flap 122, but is formed to have a shape or height that does not overlap with the oblique side of the side surface flap 122 or the engaging portion 125. The forward-extending flap 123 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 123 is a substantially rectangular surface, has approximately the same height as the rectangular portion, and a width that is approximately the same length as the shared side of the top surface (side surface 105), but is shaped to taper slightly downward. An insertion portion 124 is also integrally formed at the end of this portion so as to protrude from the center in the width direction.

[0035] The insertion portion 124 includes a gap-covering portion disposed between the rectangular portion and the locking portion 125, and a protruding portion protruding 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 recessed side 121A, and its height is approximately the same as or slightly shorter than the distance from the recessed side 121A to the locking portion 125. This allows the insertion portion 124 to be inserted into the recess of the opening flap 121 while preventing part of the box from appearing inside the locking portion 125. The protruding portion is provided with a gap from the forward-extending flap 123 and is provided so that it can deform independently due to the flexibility of the material. The protruding length of the protruding portion is preferably approximately 2 cm to 3 cm, but may have any shape as long as it overlaps with the oblique side of the side flap. This allows the insertion portion 124 to be inserted and supported in the gap formed between the opening flap 121 and the side flap 122 or the oblique side of the trapezoidal portion.

[0036] As described above, the opening flap 121 is held by alternately sandwiching it between the forward extending flap 123 and the insertion portion 124, so that the opening flap 121 does not easily deform even when force is applied from inside or outside.

[0037] The locking portion 125 is provided at approximately the center of the width of the opening flap 121 and is a portion that locks the discharge port 21 at the edge of the opening 120, and includes a part of the bottom surface (side surface 105), making it easy to separate. This also brings the discharge port 21 closer to the bottom surface, lowering the center of gravity and making it easier to aim.

[0038] Locking piece 126 is provided so as to be detachable from opening flap 121 along locking portion 125. That is, before use, a perforation is provided along the locking portion of opening flap 121. Furthermore, when in use, locking piece 126 is cut along the perforation, creating opening 120 in the area where locking piece 126 was located, with the edge of opening 120 becoming locking portion 125. This opening 120 has an upper end as locking upper edge 12A, and includes insertion region 12B which is wider than the diameter of discharge outlet 21 and allows easy insertion of discharge outlet 21, and holding region 12C adjacent thereto for holding discharge outlet 21.

[0039] The upper locking edge 12A is a detachable edge that is provided in the locking portion 125 at a position parallel to and spaced from the common edge of the opening surface 101 and the side surface 105. In the embodiment, the locking portion 125 maintains its strength by providing a gap of about 1 cm to 3 cm from the recessed edge 121A.

[0040] The insertion area 12B includes the upper edge 12A as one of its upper edges, 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 longer than the maximum length of the fixing plate 22, allowing the fixing plate 22 to be held while the outlet 21 is inserted.

[0041] Furthermore, the widthwise length of the holding area 12C is set to be approximately the same as the outer diameter of the outlet body 210, so that it interferes with the fixing plate 22 and restricts movement of the outlet 21 in the opening axial direction. The holding area 12C includes a part of the bottom surface (side surface 105), making it easy to peel off the locking piece 126 from this part. Furthermore, the height of the holding area 12C is set to be at least greater than half the outer diameter of the outlet body 210, so that the outlet 21 can be held.

[0042] 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.

[0043] FIG. 9(b) is an explanatory perspective view showing the state around the discharge port 21 in use. 9(b), the discharge port 21 is held at a position close to the bottom surface in the holding region 12C of the opening 12. In the state of FIG. 9(b), the front fixing plate interferes with the front side of the opening flap 121, preventing the inner container 2 from falling into the box body 10, and the middle fixing plate interferes with the rear side of the opening flap 121, preventing the inner container 2 from unintentionally falling out of the box body 10.

[0044] 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 122, the rearward extending flap 133 corresponding to the forward extending flap 123, and the relative insertion portion 134 corresponding to the insertion portion 124, and therefore a description of the same parts will be omitted.

[0045] 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 top surface (side surface 105) 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, an upper edge (lower base) that is shared with one side of the top surface (side surface 105), and a lower edge (upper base) that is approximately the same length as the turned edge, and the upper and lower bases are connected by symmetrical inclined edges. The upper edge (lower base) of this portion also includes a grip end 116. 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.

[0046] 《Box 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.

[0047] 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 longitudinally. On the shorter sides of each surface, forward-extending flap 123 and rearward-extending flap 133 are connected to side surface 105, which faces the top during box making; opening flap 121 and opposing opening flap 131 are connected to side surface 105, which faces the bottom; and side flap 122 and opposing side flap 132 are connected to adjacent surface 102 and adjacent opposing surface 104, which stand upright from the bottom. In the embodiment, overlapping surface 106 is arranged to overlap adjacent surface 102, but multiple surfaces may be provided so as to overlap adjacent opposing surface 104 and other surfaces as well. Next, in FIG. 2, creases are formed along the folds indicated by the solid lines on the inside of the sheet material S, and further perforations (cut lines) are formed along the perforations indicated by the dashed lines.

[0048] 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. The area of ​​the adjacent surface 102 where the gripping portion 11 is located, including the lifting portion 114, is not glued. Note that gluing may also be applied to the adjacent surface 102.

[0049] 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. 10(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.

[0050] After the manufacturer stores the inner container in the box 1 with only the opening surface 101 open, the manufacturer closes the opening 12 in the state shown in FIG. 7 as an opening closing step. In this step, the manufacturer first folds the side flaps 122 as shown in FIG. 8(a). Next, the manufacturer places the opening flap 121 so that it overlaps the forward extending flap 123 as shown in FIG. 8(b). At this time, the insertion portion 124 is placed on the back surface of the opening flap 121. Furthermore, at this time, it is preferable that the protruding portion is placed on the back surface of the side flaps 122, and the insertion portion 124 abuts against multiple surfaces, thereby more firmly holding the opening flap 121.

[0051] <<Implementation Method>> A method for carrying out the present invention will be described in detail below with reference to the drawings. The present invention is carried out by a user who holds the box 1 and dispenses the fluid in the inner container 2. 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.

[0052] First, as a locking portion operating step, the user separates the locking piece 126 along the locking portion 125 as shown in FIG. 9(a).

[0053] Next, as the outlet pulling-out step, the user pulls out outlet 21 as shown in Figure 9(b). The user finds outlet 21 by inserting their finger into insertion region 12B, then grasps outlet 21 and pulls it out of insertion region 12B. The user then inserts outlet 21 into holding region 12C so that fixing plate 22 is positioned between locking portion 125. At this time, the edges of insertion region 12B and holding region 12C are connected at an angle, which makes it easy to fix outlet 21 to holding region 12C. As a result, outlet 21 is firmly held in a predetermined position in opening 12.

[0054] Next, as a gripping and pulling-out step, the user lifts the finger hook portion 110 on the adjacent surface 102 as shown in Fig. 3(b). That is, the user forms a hole 111 into which a finger can be inserted by pulling or pushing the blocking portion 112 out of the adjacent surface 102 as shown in Fig. 6. At this time, the blocking portion 112 can be easily lifted because it is adjacent to the lifting portion 114.

[0055] Finally, as shown in Fig. 5, the user supports the grip portion 11 with both hands and dispenses the fluid. That is, the user grasps the finger hook portion 110A on the adjacent surface 102 with one hand and the finger hook portion 110A on the adjacent facing surface 104 with the other hand, which makes it easier to hold firmly and adjust the orientation of the discharge port 21, thereby improving usability. Furthermore, the user can switch their hand from the finger hook portion 110A closer to the opening facing surface 103 to the finger hook portion 110A closer to the opening surface 101, making it possible to use the dispenser in a manner that is easy to hold for a variety of users, regardless of whether they are left-handed or right-handed.

[0056] First Change Example A first modified example of the present invention is shown in Fig. 11. In the modified example shown in Fig. 11, adjacent surface 102 is provided on the top surface side of box body 10, and a pair of finger hooks 110 are formed so as to extend in a substantially rectangular shape from a position close to opening surface 101 toward a position close to opening opposing surface 103. The axis of this rectangle is set parallel to the opening axis, and the central axis of finger hook 110A is set so as to substantially coincide with the opening axis in a plan view, making it easier to aim the discharge. Furthermore, the distance between connecting sides 113 of finger hook 110A is shorter than half the length of finger hook 110A in the shorter direction, so that when finger hook 110A is grasped, it forms a truss when viewed from the front, making it easy to hold. This allows the user to grip any position on the long finger hook portion 110, making it possible to use it in a variety of ways.

[0057] Second modification example A second modified example of the present invention is shown in Figure 12. In the second modified example, a tear line 15 is provided for disassembling the box body 10. The tear line 15 extends parallel to the outer periphery of the opening surface 101, surrounding the adjacent surface 102, the opposing adjacent surface 104, and the side surface 105. Furthermore, by providing the tear line 15 between the opening surface 101 and the finger hook 110, the opening 12 can be cut out from the box body 10 to expose the inner container 2 from the box body 10, facilitating separation.

[0058] Third modification example A third modified example of the present invention is shown in Figures 13 to 15. In this third modified example, the adjacent surface 102 is provided on the top surface of the box body 10. The grip portion 11 is provided on the adjacent surface 102 with a slit when not in use, and is provided so that when in use, it can be lifted along the slit and at least partially separated from the adjacent surface 102. The grip portion 11 has a rectangular main grip portion 115 that is gripped by the user at the center, finger hook portions 110 branching from both ends of the main grip portion 115 toward the opening surface 101 and the opening opposing surface 103, and a grip end portion 116 that is provided on the finger hook portion 110 and connects the end portion to the opening surface 101 or the opening opposing surface 103. In addition, a lifting portion 114 is provided adjacent to the main grip portion 115.

[0059] Finger hook 110 is provided so as to branch into two from main gripping portion 115, and the branched portions are arranged in parallel and are positioned closer to side surface 105 in plan view than the side edge of main gripping portion 115, which makes it easier to rotate around the opening axis by holding these gripping portions 110 compared to Patent Document 1. In addition, a crease that allows a valley fold is provided at the boundary with main gripping portion 115, making main gripping portion 115 easier to hold. The finger hook 110 is formed to form a U-shaped portion in a plan view (hereinafter simply referred to as the U-shaped portion), and its edges are smooth and continuous, increasing its strength. This U-shaped portion is formed to occupy approximately 1 / 5 to 1 / 3 of the entire length of the adjacent surface 102, allowing the main gripping portion 115 to be held stably while being gripped. Finger hook 110 includes side 11B that is approximately parallel to opening surface 101, and by gripping this side, the user can easily hold grip portion 11 and enable stable operation. The distance between the protrusions of the U-shaped portion is at least larger than the width of discharge outlet 21, and preferably is set to be approximately the same as or slightly larger than the width of locking portion 125, making it easier to grip the portion between them. Furthermore, on opening surface 101, discharge outlet 21 is positioned between the branching finger hooks 110, making it easier to aim the discharge. Preferably, discharge outlet 21 is positioned on a line that is parallel to and equidistant from the two grip portions that extend in parallel on opening surface 101, making it easier to adjust and aim.

[0060] When separated for use, the finger hooks 110 form holes 111 that partially include the edges of the adjacent surface 102, as shown in the figure. The holes 111 are provided symmetrically with respect to a center line extending in the short direction of the adjacent surface 102, and the pair of finger hooks 110 function as paired finger hooks 110A.

[0061] The lifting portion 114 is a cutout portion provided to include the side edge of the main gripping portion 115, and creates a step between the adjacent surface 102 and the overlapping surface 106. This exposes the side edge of the gripping portion 11 on the adjacent surface 102, making it easier to lift. The lifting portion 114 is provided near the center of the longitudinal direction of the adjacent surface 102, so that when the main gripping portion 115 is lifted, a uniform force is applied to each of the gripping ends 116.

[0062] The grip end 116 is integrally connected to the end of the finger hook 110, and is a part provided on the opening surface 101 or the opposing surface 103 of the opening, and is capable of lifting the entire grip portion 11 by deforming as shown in Figures 17 and 18. Note that, for the sake of simplicity, the side flaps 122 or the opposing side flaps 132 are omitted in Figures 17 and 18.

[0063] 2 and 5, at least one side of the gripping end 116 is a boundary side 116A that includes the boundary between the surfaces. The boundary side 116B opposite the boundary side 116A 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 gripping end 116 is a rectangular member that is wide in the width direction.

[0064] The main gripping portion 115 is a generally rectangular portion provided at approximately the center in the short direction on the adjacent surface 102, extending parallel to the opening axis, and is provided so that at least a portion of it can be separated to a height where a finger can be placed. The main gripping portion 115 is connected to the finger hook portion 110 at both ends.

[0065] By bending the boundary-facing side 116B from the state shown in Fig. 15(a) toward the inside of the box body 10, the gripping end 116 is tilted inward as shown in Fig. 15(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 116 interfere with each other, making it possible to control the maximum angle of tilt. Furthermore, part of the boundary side 116A 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. The box X having the above-described configuration can be held, for example, with the entire palm of the hand from the front and back, making it easy to use for a variety of users.

[0066] Fourth Change A fourth modified example of the present invention is shown in Fig. 18. In this modified example, adjacent surface 102 is located on the top surface side of box body 10, and grip portion 11 is provided with a slit on adjacent surface 102, similar to the third modified example. Grip portion 11 has finger hook portion 110 whose axis is provided parallel to opening surface 101, and has grip end portion 116 at the end of finger hook portion 110.

[0067] Finger hook 110 is a substantially rectangular part arranged so that its axis connects side surfaces 105 at the shortest distance, and in this modified example, it is provided at a position close to opening surface 101 and a position close to opening opposing surface 103, so as to be symmetrical with respect to a center line extending in the short direction of adjacent surface 102, forming finger hook 110A. Finger hook 110 has a width of about 1 cm to 4 cm, which is shorter than the distance between the user's finger joints, making it easy to grip. At the end of the finger hook 110, a gripping end 116 having a configuration similar to that shown in the third modified example is formed, so that the finger hook 110 can be separated and lifted up. As shown in the figure, the finger hook portion 110 has a hole 111 formed by the raised edge and the adjacent surface 102, and the finger can be inserted into the hole 111 to be hooked for support. The user can slide his / her fingers within the range of the finger hook 110, making it easy to use in various ways. Furthermore, a lifting portion 114 may be provided adjacent to the finger hook portion 110 to make it easier to separate from the unused state.

[0068] 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.

[0069] Furthermore, the finger hook portion 110 is arranged to be capable of being transformed from an unused state to a used state, and in the unused state, it is arranged on the surface of the adjacent surface 102, so that it can be stored compactly and securely in the unused state.
