Description

The present invention relates to a packaging container that stores a stored item in a fixed state.

Bottled beverages such as wine and concentrated beverages may be stored in a box. Bottles of this type are often cylindrical with a bottom (bottomed). Therefore, if it is stored in the box as it is, the bottle is not stable inside the box. In order to store the bottle stably, for example, Japanese Utility Model Laid-Open No. 6-49319 discloses a bottle holder that is placed inside a box to hold the bottle.

In Japanese Utility Model Laid-Open No. 6-49319, a paper bottle body holder formed in a frame shape and a paper bottle shoulder holder formed in a horizontal triangular cylinder are housed in a gift box. There is. The bottle shoulder holding body includes a shoulder holding plate having a shoulder holding semi-elliptical hole and a body holding plate having a body holding semi-elliptical hole communicating with the shoulder holding semi-elliptical hole. The shoulder holding plate is arranged obliquely with respect to the bottom of the gift box, and the body holding plate is provided upright with respect to the bottom. By fitting the upper portion of the bottle into the shoulder-holding semi-elliptical hole and the body-holding semi-elliptical hole, the bottle is stably held.

Japanese Utility Model Publication No. 6-49319

However, in Japanese Utility Model Laid-Open No. 6-49319, a holder for holding a bottle must be additionally provided in addition to the box, and the amount of paper required for assembling the box increases. Further, since the holder itself is supported only by the bottom surface, the bottle may move during transportation.

It is an object of the present invention to provide a packaging container that can hold a stored item in a stable manner and can easily attach and detach the stored item.

In order to achieve the above-mentioned object, the packaging container of the present invention includes a storage portion having a peripheral wall including a pair of opposing first and second side walls standing on a bottom wall and having an open top surface. The first side wall and the second side wall include an outer surface plate bent upward from the bottom wall, an upper surface plate bent inward from an upper end of the outer surface plate, and a lower surface extending from an inner end of the upper surface plate. And an inner face plate that is bent into. The inner surface plates facing each other have through holes for holding the stored items by fitting.

With this configuration, it is possible to hold the stored item without providing a holding member for holding the stored item inside the storage section. Therefore, it is possible to reduce the amount of materials used, reduce the cost, and reduce the weight of the packaging container itself. Further, since the stored items are held by fitting the two places (both ends) into the through holes, it is possible to stably hold the stored items. Therefore, even when the stored items are transported while being stored, the stored items are unlikely to shift or move. Therefore, it is possible to suppress deformation and deterioration of the stored items. Further, since the stored item can be held only by fitting it into the through hole, the stored item can be easily attached and detached. Therefore, it is possible to improve the convenience of the user.

In the above configuration, the first side wall may be capable of tilting the upper end toward the outer peripheral side with the lower end as the center. With this configuration, it is possible to easily remove the holding of the stored item by the through hole provided on the first side wall side. This makes it easier to attach and detach the stored items and further enhances the convenience of the user.

In the above configuration, at least one of the outer surface plate and the inner surface plate of the first side wall includes a side surface flap bent inward from a side end. The peripheral wall adjacent to the first side wall is formed by bending so that the side surface flap can be inserted. The upper end of the side flap is inclined downward toward the free end. With this configuration, since the side surface flap of the first side wall is housed in the peripheral wall, it is possible to increase the strength of the corner portion of the packaging container. Further, the first side wall can be easily tilted to the outer peripheral side. Therefore, the strength of the packaging container can be increased and the stored items can be easily attached and detached, and the convenience of the user can be further increased.

The through hole may have a shape that includes a part of a polygon that allows the stored item to be inscribed. With this configuration, the through hole can hold the outer surface of the stored item at a plurality of points. Further, at least one side of the polygon may be curved inwardly at least on one side of the through hole provided in at least one of the inner surface plate of the first side wall and the inner surface plate of the second side wall. Thereby, when inserting the stored item, the side portions of the polygon can be deformed, and the stored item is more firmly held.

In the above configuration, a lid member that covers the upper surface of the storage unit is further provided. The lid member includes at least an outer fitting plate that is fitted onto the outer surface plate of the first side wall. With this configuration, when the lid member is attached, the outer fitting plate presses the outer surface plate of the first side wall. Therefore, even when vibration or force acts on the packaging container during transportation or the like, tilting of the first side wall toward the outer peripheral side is suppressed. As a result, the packaging container can suppress misalignment and movement of stored items during transportation.

In the above structure, a bottom surface flap that is bent inward from the lower end of the inner surface plate, and a support piece that is formed by a notch provided in the inner surface plate and that projects outward from the bottom surface flap and contacts the inner surface of the outer surface plate. And may be further provided. With this configuration, the outer surface plate and the inner surface plate are connected such that the upper end thereof is connected by the upper surface plate and the lower end thereof is held by the support piece at a constant interval. Therefore, the distance between the outer surface plate and the inner surface plate can be kept constant. This makes it possible to keep the length of the portion protruding from the through hole of the stored item constant, and to hold the stored item more stably.

In the above configuration, the cut may extend from a fold line of a boundary between the bottom surface flap and the inner surface plate to form a side edge of the through hole. With this configuration, the support piece and the bottom flap can be formed on the same surface. Therefore, by bending the bottom flap along the fold line provided at the boundary between the lower end of the inner face plate and the bottom face flap, the support piece can be projected toward the outer face plate. This makes it possible to reduce the assembly work. Further, the amount of material can be reduced as compared with the case where the support piece is separately provided.

According to the packaging container of the present invention, the stored items can be stably held and the stored items can be easily attached and detached.

As shown in FIGS. 2 and 3, the storage box 100 has a rectangular bottom portion 101, and a peripheral wall 102 extending upward from each of the four sides of the bottom portion 101. The storage box 100 is provided with a storage portion 60 having an opening at the top. As shown in FIGS. 2 and 3, the peripheral wall 102 includes a first side wall 1, a second side wall 2, a third side wall 3, and a fourth side wall 4, and the bottom portion 101 includes a bottom wall 5 ( (See FIG. 4 etc.). The storage box 100 has a rectangular parallelepiped shape in plan view, and the first side wall 1 and the second side wall 2 face each other. Further, the third side wall 3 and the fourth side wall 4 face each other. That is, the first side wall 1 and the second side wall 2 form a pair, and the third side wall 3 and the fourth side wall 4 form a pair.

As shown in FIG. 4, the storage box 100 is formed by bending a paper sheet Ps. In addition, in the paper sheet Ps shown in FIG. 4, the edge portion is shown by a solid line, and the folding line which is a folding line is shown by a one-dot chain line.

As shown in FIG. 4, the bottom wall 5 has a rectangular shape. The first side wall 1 and the second side wall 2 are connected to each of the pair of long sides of the bottom wall 5. The third side wall 3 and the fourth side wall 4 are connected to each of the pair of short sides of the bottom wall 5. That is, the peripheral wall 102 is erected on the bottom wall 5.

(2.1 About the first side wall 1)
As shown in FIGS. 2 to 4, the first side wall 1 includes a first outer face plate 11, a first upper face plate 12, a first inner face plate 13, and a first side face flap 14 (see FIGS. 4 and 5 and the like). ), a first bottom surface flap 15 (see FIGS. 4 and 5), and a first support piece 16.

The first outer surface plate 11 has a rectangular shape. The first outer surface plate 11 is connected to the long side of the bottom wall 5. The first outer surface plate 11 is bent upward along the long side of the bottom wall 5. The first upper surface plate 12 is connected to the upper end of the first outer surface plate 11. The first upper surface plate 12 is bent inward at the upper end of the first outer surface plate 11. The inner surface of the first upper surface plate 12 is shorter than the outer surface thereof, and has a trapezoid shape. Although details will be described later, the shape is such that interference with the third upper surface plate 32 of the third side wall 3 and the fourth upper surface plate 42 of the fourth side wall 4 is suppressed.

The first inner surface plate 13 is connected to the inner end of the first upper surface plate 12. The first inner surface plate 13 is bent downward at the inner end of the first upper surface plate 12. The lower end of the first inner surface plate 13 contacts the bottom wall 5. The first inner surface plate 13 has three first through holes 131 formed therein. The first through holes 131 are formed at equal intervals in the longitudinal direction of the first inner surface plate 13, here, the front-rear direction. The number of the first through holes 131 is not limited to three.

As shown in FIG. 4, the first through hole 131 has a combination of an octagonal shape arranged on the upper side and a trapezoidal shape arranged on the lower side. More specifically, the first through hole 131 has a shape in which an octagon and a trapezoid are stacked so that one side of the lower end of the octagon matches the upper base of the trapezoid. That is, the first through hole 131 includes an octagonal portion arranged in the upper portion and a trapezoidal portion arranged in the lower portion. The octagonal part has the same length on five sides except the side that matches the trapezoidal upper base and the two adjacent sides. Further, the octagonal portion is a shape having a circle inscribed on all sides. Then, the first through hole 131 is a line-symmetrical figure with respect to a vertical line passing through the center of the octagonal portion.

The trapezoidal portion reaches the boundary (fold line) between the first inner surface plate 13 and the first bottom surface flap 15. In the paper sheet Ps illustrated in FIG. 4, the oblique side of the trapezoidal portion is the cut 133, and the cut 133 forms the edge of the first through hole 131. The trapezoidal portion sandwiched by the cuts 133 is the first support piece 16.

The first bottom surface flap 15 is connected to the lower end of the first inner surface plate 13. The first bottom surface flap 15 is bent inward at the lower end of the first inner surface plate 13 (see FIG. 5). The first bottom surface flap 15 has a rectangular shape with a notch 151 at the end on the fourth sidewall 4 side. The notch 151 is provided to suppress interference with the third bottom surface flap 34 of the third side wall 3 described later.

The first support piece 16 is formed integrally with the first bottom surface flap 15. That is, when the first bottom surface flap 15 is bent at the lower end of the first inner surface plate 13, the first support piece 16 falls toward the outside of the first inner surface plate 13. Then, the free end of the first support piece 16 contacts the first outer surface plate 11 (see FIG. 2 ).

The first side surface flap 14 includes a first outer side flap 141 and a first inner side flap 142 (see FIG. 4, FIG. 5, etc.). In the storage box 100, the first outer flap 141 and the first inner flap 142 are paired in the front-rear direction. The first side flap 14 of the present embodiment includes both the first outer flap 141 and the first inner flap 142, but either one may be provided. That is, the first side surface flap 14 may include at least one of the first outer side flap 141 and the first inner side flap 142.

The pair of first outer flaps 141 are continuously provided on both side ends of the first outer face plate 11, here, front and rear ends. The upper end of the first outer flap 141 is inclined downward toward the free end. The upper end of the first outer flap 141 can be, for example, an arc shape, an elliptic arc shape, a complex arc shape including arcs having a plurality of curvatures, but is not limited thereto. Further, it may be a part of a straight line or a polygonal line having a plurality of corners.

The pair of first inner flaps 142 are continuously provided on both end sides of the first inner surface plate 13, here, front and rear ends. The first inner flap 142 has substantially the same configuration as the first outer flap 141 except that the first inner flap 142 is connected to the first inner face plate 13. Therefore, details of the first inner flap 142 are omitted.

At the boundary of the first inner surface plate 13 and the first inner flap 142, a vertically extending rectangular locking hole 132 is provided. The locking hole 132 is a through hole, and has a locking claw 331 provided on a third inner surface plate 33 of the third side wall 3 described later and a locking claw provided on a fourth inner surface plate 43 of the fourth side wall 4 described later. 431 can be inserted.

(2.2 Regarding the second side wall 2)
As shown in FIGS. 3 and 4, the second side wall 2 includes a second outer surface plate 21, a second upper surface plate 22, a second inner surface plate 23, a second side surface flap 24, a folded portion 25, The second bottom surface flap 26 and the second support piece 27 are provided.

The second outer surface plate 21 has a rectangular shape. The second outer plate 21 is connected to the long side of the bottom wall 5. The second outer surface plate 21 is bent upward along the long side of the bottom wall 5.

The second upper surface plate 22 is connected to the upper end of the second outer surface plate 21. The second upper surface plate 22 is bent inward at the upper end of the second outer surface plate 21. The second upper surface plate 22 includes a pair of convex portions 221 protruding inward at both ends, that is, both front and rear ends (see FIG. 6 ). The pair of convex portions 221 partially overlaps the third upper surface plate 32 of the third side wall 3 and the fourth upper surface plate 42 of the fourth side wall 4, respectively. The second side wall 2 and the third side wall 3 are firmly fixed by the protrusion 221 and the third upper surface plate 32 overlapping each other. Similarly, the convex portion 221 and the fourth upper surface plate 42 overlap each other, so that the second side wall 2 and the fourth side wall 4 are firmly fixed.

The second inner surface plate 23 is connected to the inner end of the second upper surface plate 22. The second inner surface plate 23 is bent downward at the inner end of the second upper surface plate 22. The lower end of the second inner surface plate 23 contacts the bottom wall 5. The second inner surface plate 23 is formed with three second through holes 231. The second through holes 231 are formed at equal intervals in the longitudinal direction of the second inner surface plate 23, here, the front-rear direction. The number of second through holes 231 is not limited to three.

As shown in FIG. 4, the second through hole 231 has a shape obtained by combining a decagon arranged on the upper side and a rectangle arranged on the lower side. More specifically, the second through hole 231 has a shape in which a decagon and a rectangle are stacked so that one side of the lower end of the decagon coincides with the long side of the rectangle. That is, the second through hole 231 includes a decagonal portion arranged in the upper portion and a rectangular portion arranged in the lower portion. In addition, the shape of the decagonal portion is, here, a shape in which the sides connected to both ends of one side of the lower end of the regular octagon are bent outward. The decagonal portion is a shape having a circle that can be inscribed on all sides.

With such a configuration, the number of sides that come into contact with the stored item S increases and the lower end portion of the stored item S can be held more firmly than in the case of the octagonal shape. In addition, when the stored item S has a sufficient strength to support the stored item S in the second through hole 231, such as the stored item S is lightweight, the second inner face plate 23 is thick, and the like, the side bent outward is linear. That is, it may have an octagonal shape. The second through hole 231 is a line-symmetrical figure with respect to a vertical line passing through the center of the decagonal portion.

The rectangular portion reaches the boundary (fold line) between the second inner surface plate 23 and the second bottom surface flap 26. As shown in FIG. 4, one side of the lower end of the decagonal portion of the second through hole 232 and the short side of the rectangle are continuous. The two sides adjacent to one side of the lower end of the decagonal portion and the short sides of the rectangle are part of the cut 232. The cut 232 forms a part of the edge of the second through hole 231. In the second inner surface plate 23, the upper portion of the portion sandwiched by the cuts 232 of the second through hole 231 is removed. That is, the portion sandwiched by the cuts 232 is the second support piece 27. The second support piece 27 is formed integrally with the second bottom surface flap 26. The rectangular portion may be omitted, and the lower end side of the decagonal portion may be aligned with the boundary with the second bottom surface flap 26. In this case, the side adjacent to both ends of the lower side of the decagonal portion is the cut 232.

The second through hole 231 is larger than the first through hole 131. In addition, the three first through holes 131 and the three second through holes 231 are paired, respectively. That is, the first inner surface plate 13 of the first side wall 1 and the second inner surface plate 23 of the second side wall 2 are provided with three pairs of through holes (first through hole 131 and second through hole 231). The three pairs of through holes respectively fit and hold the upper end portion and the lower end portion of the stored item S. Then, in the storage box 100 of the present embodiment, the distance from the center bottom 101 of the octagonal portion of the first through hole 131 and the distance from the center bottom 101 of the decagonal portion of the second through hole 231. Are equal. By doing so, the stored item S is stored in the storage box 100 with the central axis parallel to the bottom portion 101. Thereby, the storage box 100 can hold the storage item S more stably.

The second bottom surface flap 26 is connected to the lower end of the second inner surface plate 23. The second bottom surface flap 26 is bent inward at the lower end of the second inner surface plate 23 (see FIG. 6). As shown in FIG. 4, the second bottom surface flap 26 has a rectangular shape having a notch 261 in the end portion on the third side wall 3 side. The notch 261 suppresses interference with the third bottom surface flap 34 of the third side wall 3, which will be described later.

The second support piece 27 has a side extending from the corner of the lower end side of the decagon-shaped portion and the side opposite to the adjacent side toward the inside of the decagon-shaped portion, and the tip of the side. It has a connected side (free end). The second support piece 27 is formed integrally with the second bottom surface flap 26. When the second bottom surface flap 26 is bent at the lower end of the second inner surface plate 23, the second support piece 27 moves together with the second bottom surface flap 26 and falls toward the outside of the second inner surface plate 23. Then, the free end of the second support piece 27 contacts the second outer surface plate 21 (see FIG. 3, FIG. 6, etc.).

In the storage box 100, the second side flaps 24 are provided in pairs. The pair of second side surface flaps 24 are continuously provided on both side ends of the second inner surface plate 23, here, front and rear ends. The second side flap 24 has a rectangular shape, and the two corners of the free end thereof are chamfered with curves (arcs). However, the shape is not limited to this, and chamfering may be omitted. The second side flap 24 is not limited to the rectangular shape, but may be a semi-ellipse, a triangle, a trapezoid, or the like.

The pair of folding parts 25 are provided at both ends of the second outer surface plate 21, respectively. One of the folded portions 25 communicates with the front end of the second outer plate 21 and the side end of the third outer plate 31 of the third side wall 3. The other folded portion 25 communicates with the rear end of the second outer plate 21 and the side end of the fourth outer plate 41 of the fourth side wall 4. The folding part 25 has a folding line extending outward from the apex of the bottom wall 5, and the folding part 25 can be overlapped by folding at this folding line (see FIGS. 7 and 8).

(2.3 About the third side wall 3)
As shown in FIGS. 2, 3, and 4, the third side wall 3 includes a third outer surface plate 31, a third upper surface plate 32, a third inner surface plate 33, and a third bottom surface flap 34.

The third outer surface plate 31 has a rectangular shape. The third outer surface plate 31 is connected to the short side of the bottom wall 5. The third outer surface plate 31 is bent upward at the short side of the bottom wall 5. The third upper surface plate 32 is connected to the upper end of the third outer surface plate 31. The third upper surface plate 32 is bent inward at the upper end of the third outer surface plate 31.

The third inner surface plate 33 is connected to the inner end of the third upper surface plate 32. The third inner surface plate 33 is bent downward at the inner end of the third upper surface plate 32. The lower end of the third inner surface plate 33 contacts the bottom wall 5. A locking claw 331 is provided at an end of the third inner surface plate 33 on the first side wall 1 side. The locking claw 331 is a wedge type in which the third inner surface plate 33 is bent downward from the inner end of the third upper surface plate 32 and protrudes outward as it goes upward (see FIG. 4 and the like).

The third bottom surface flap 34 is connected to the lower end of the third inner surface plate 33. The third bottom surface flap 34 is bent inward at the lower end of the third inner surface plate 33. Both ends of the free end of the third bottom surface flap 34 are obliquely cut. By being cut, the interference with the first bottom surface flap 15 and the second bottom surface flap 26 is suppressed. Further, a U-shaped cut is formed at the lower end of the third inner surface plate 33, and the fixing hole 332 is formed by bending the third bottom surface flap 34.

(2.4 About Fourth Side Wall 4)
As shown in FIGS. 2, 3, and 4, the fourth side wall 4 includes a fourth outer surface plate 41, a fourth upper surface plate 42, a fourth inner surface plate 43, and a bottom surface cover 44.

In the fourth side wall 4, the fourth outer surface plate 41, the fourth upper surface plate 42, and the fourth inner surface plate 43 are respectively the third outer surface plate 31, the third upper surface plate 32, and the third inner surface plate 33 of the third side wall 3. It has substantially the same configuration. Therefore, detailed description of the fourth outer plate 41, the fourth upper plate 42, and the fourth inner plate 43 will be omitted. Like the third inner surface plate 33, the fourth inner surface plate 43 is provided with a locking claw 431 on the side of the first side wall 1 and can be inserted into the locking hole 132 of the first inner surface plate 13.

The bottom cover 44 is connected to the lower end of the fourth inner surface plate 43. The bottom cover 44 is bent inward at the lower end of the fourth inner surface plate 43. The bottom cover 44 has a rectangular shape having substantially the same size as the portion of the bottom wall 5 surrounded by the peripheral wall 102. The bottom cover 44 has a convex portion 441 at its free end. The bottom cover 44 covers the inner surface of the bottom wall 5 and inserts the convex portion 441 into a fixing hole 332 provided in the third inner surface plate 33 (see FIG. 3 ). As a result, the bottom cover 44 is fixed to the inner surface of the bottom wall 5. The bottom cover 44 reinforces the bottom wall 5 of the storage box 100. That is, by making the bottom wall 5 and the bottom cover 44 double, the strength of the bottom portion 101 of the storage box 100 is increased.

(3. Assembling the storage box 100)
Next, a procedure for assembling the storage box 100 will be described with reference to the drawings.

In the storage box 100 of this embodiment, the first side wall 1, the second side wall 2, the third side wall 3, and the fourth side wall 4 are assembled in this order. The assembly procedure is not limited to this. For example, the procedure of assembling the first side wall 1 and the second side wall 2 may be reversed. That is, if the fourth side wall 4 is finally assembled, the order of assembling the other side walls is not particularly limited.

(3.1 Assembly of the first side wall 1)
As shown in FIG. 5, each plate material of the first outer surface plate 11, the first upper surface plate 12, the first inner surface plate 13, and the first bottom surface flap 15 is bent along a folding line to form the first side wall 1. The bending direction of each plate material has been described above, and thus detailed description thereof will be omitted.

The first support piece 16 is formed integrally with the first bottom surface flap 15. When the first bottom surface flap 15 is bent inward with respect to the first inner surface plate 13, the first support piece 16 is displaced integrally with the first bottom surface flap 15. The first support piece 16 moves to the side opposite to the first bottom surface flap 15 and contacts the inner surface of the first outer surface plate 11. As a result, the first support piece 16 supports the first inner surface plate 13 so as to maintain a constant distance with respect to the first outer surface plate 11.

The first outer surface plate 11 and the first inner surface plate 13 are substantially parallel to each other. In this state, the first bottom surface flap 15 is bonded to the bottom wall 5. The adhesion may be performed by an adhesive or an adhesive tape may be used. Further, it is not limited to adhesion, and a part of the first bottom surface flap 15 is surely attached to the bottom wall 5 by inserting a part of the first bottom surface flap 15 into a through hole (not shown) provided in the bottom wall 5. A wide range of fixing methods can be adopted. The first support piece 16 may also be bonded to the bottom wall 5. Further, finally, since the bottom cover 44 covers the upper portion of the first bottom flap 15, when the first side wall 1 has sufficient strength to support the stored item S, the first bottom flap 15 is fixed to the bottom wall 5. Need not be fixed to.

In the first side wall 1, the first outer surface plate 11 is integrated with the bottom wall 5, and the first inner surface plate 13 is fixed to the bottom wall 5 via the first bottom surface flap 15. Therefore, the upper end of the first side wall 1 can be tilted outward with the lower end as the center. Details of the tilting of the first side wall 1 will be described later.

(3.2 Assembly of Second Sidewall 2)
Next, the second side wall 2 is assembled. As shown in FIG. 6, each plate material of the second outer surface plate 21, the second upper surface plate 22, the second inner surface plate 23, and the second bottom surface flap 26 is bent along a folding line to form the second side wall 2. The bending direction of each plate material has been described above, and thus the details will be omitted.

The second support piece 27 is formed integrally with the second bottom surface flap 26. When the second bottom surface flap 26 is bent inward with respect to the second inner surface plate 23, the second support piece 27 is displaced together with the second bottom surface flap 26. The second support piece 27 moves to the side opposite to the second bottom surface flap 26 and contacts the inner surface of the second outer surface plate 21. As a result, the second support piece 27 supports the second inner surface plate 23 so as to maintain a constant distance with respect to the second outer surface plate 21.

The second outer surface plate 21 and the second inner surface plate 23 are substantially parallel to each other. In this state, the second bottom surface flap 26 is bonded to the bottom wall 5. The bonding is the same as that of the first bottom surface flap 15. That is, as long as the second bottom surface flap 26 can be fixed to the bottom wall, the adhesion is not limited. The second support piece 27 may also be bonded to the bottom wall 5. Further, since the bottom cover 44 covers the upper portion of the second bottom flap 26, if the second side wall 2 has sufficient strength to support the stored item S, the second bottom flap 26 is not fixed to the bottom wall 5. May be.

(3.3 Assembly of Third Side Wall 3)
After assembling the first side wall 1 and the second side wall 2, the third side wall 3 is formed. As shown in FIG. 7, the first outer flap 141 and the first inner flap 142 on the front side of the first side wall 1 are folded inward at the fold lines of the side ends of the first outer face plate 11 and the first inner face plate 13, respectively. It will be tuned. The second side flap 24 is bent inward at the side end of the second inner face plate 23.

The folding portion 25 is connected to both the second outer surface plate 21 and the third outer surface plate 31. Therefore, the folding portion 25 is bent along the folding line at the boundary with the second outer surface plate 21 and the folding line at the boundary with the third outer surface plate 31. The folding part 25 is bent along the central folding line at the same time as this folding. As a result, the folding section 25 is folded in half along the center folding line.

In this state, the third upper surface plate 32, the third inner surface plate 33, and the third bottom surface flap 34 are bent along the fold line to form the third side wall 3. The third bottom surface flap 34 includes notches with both ends cut obliquely. This cutout does not interfere with the cutout 151 of the first bottom surface flap 15 and the cutout 261 of the second bottom surface flap 26. Therefore, it is possible to prevent the sheets from overlapping and becoming partially thick. As a result, the entire surface of the third bottom surface flap 34 comes into contact with the bottom wall 5, so that the third bottom surface flap 34 is unlikely to rise.

By forming the third side wall 3 by bending, the first outer flap 141, the first inner flap 142, the second side flap 24, and the folded folding portion 25 form the third outer surface plate 31 and the third inner surface plate. It is inserted in the space between 33. Further, due to the formation of the third side wall 3, one part of the convex portion 221 of the second upper surface plate 22 of the second side wall 2 is covered with the third upper surface plate 32. Further, the locking claws 331 provided on the third inner surface plate 33 are inserted into the locking holes 132 of the first inner surface plate 13.

(3.4 Assembly of Fourth Side Wall 4)
Finally, the fourth side wall 4 is assembled. As shown in FIG. 8, the first outer flap 141 and the first inner flap 142 on the rear side and the second side flap 24 on the rear side are bent inward. Further, the rear folding part 25 is folded in two.

Then, the fourth outer surface plate 41, the fourth upper surface plate 42, the fourth inner surface plate 43, and the bottom surface cover 44 are each folded along a folding line.

The bottom cover 44 has substantially the same size as a rectangle surrounded by the first inner surface plate 13, the second inner surface plate 23, the third inner surface plate 33, and the fourth inner surface plate 43. Therefore, the bottom cover 44 is a portion surrounded by the first inner surface plate 13, the second inner surface plate 23, the third inner surface plate 33, and the fourth inner surface plate 43 on the bottom surface of the storage box 100 after being folded along the folding line. It is arranged so as to cover. Then, the convex portion 441 provided on the free end of the bottom cover 44 is inserted into the fixing hole 332 provided on the third inner surface plate 33.

One of the short sides of the rectangular bottom cover 44 is connected to the fourth inner surface plate 43. The remaining short side of the bottom cover 44 contacts the third inner surface plate 33. That is, the third inner surface plate 33 is pushed by the bottom surface cover 44. The bottom cover 44 is prevented from floating by inserting the protrusion 441 into the fixing hole 332. Further, since it is held by the bottom surface cover 44, the floating of the third bottom surface flap 34 is also suppressed. Thereby, even if the third side wall 3 and the fourth side wall 4 are not adhered to the bottom wall 5, they are not easily disassembled.

Then, the first side surface flap 14, the second side surface flap 24, and the folding portion 25 on the front side are provided in a space surrounded by the third outer surface plate 31, the third upper surface plate 32, and the third inner surface plate 33 of the third side wall 3. Is inserted. A space in which the first side surface flap 14, the second side surface flap 24, and the folded portion 25 on the rear side are surrounded by the fourth outer surface plate 41, the fourth upper surface plate 42, and the fourth inner surface plate 43 of the fourth side wall 4. Inserted in. As a result, the first side wall 1, the second side wall 2, the third side wall 3, and the fourth side wall 4 are connected in an upright state.

Next, the storage of the storage item S in the storage box 100 will be described. FIG. 9 is a perspective view showing a state where the storage item S is stored in the storage box 100. As shown in FIG. 9, the stored item S is a cylindrical container having different upper and lower outer diameters. Examples of the stored items S include, but are not limited to, juices, beverages such as alcohol, cosmetics, pharmaceuticals, and the like.

As shown in FIG. 9, the storage item S is stored in the storage part 60 by inserting the lower end portion of the storage item S into the second through hole 231 and the upper end portion into the first through hole 131. Be seen. At this time, the body of the stored item S is supported by the bottom cover 44 that covers the bottom wall 5, that is, the bottom 101 of the storage box 100.

The lower end of the stored item S is inserted into the second through hole 231. At this time, each side of the decagonal portion of the second through hole 231 contacts the outer surface of the lower end of the stored item S. That is, the lower end of the stored item S is fitted into the decagonal portion of the second through hole 231. Therefore, the lower end of the stored item S is stably held by the peripheral portion of the second through hole 231, that is, the rotation of the lower end of the stored item S is suppressed.

In addition, the lower end of the stored item S is held by each side of the decagonal portion, so that the diameter of the circle inscribed in the decagonal portion of the second through hole 231 and the outer diameter of the stored item S are increased. Insertion is possible even when the sizes of the and are different. For example, when the outer diameter of the lower end of the stored item S is larger than the diameter of the circle inscribed in the second through hole 231, the lower end of the stored item S deforms the decagonal portion of the second through hole 231. Can be inserted. As a result, the lower end of the stored item S is firmly held by the peripheral edge of the second through hole 231. On the contrary, when the outer diameter of the lower end of the stored item S is smaller than the diameter of the circle inscribed in the second through hole, the lower end of the stored item S has a plurality of decagonal portions of the second through hole 231. Supported by the side of. From this, even if there is an error in the outer diameter of the lower end of the stored item S and the diameter of the circle inscribed in the second through hole 231, the lower end of the stored item S is firmly held.

Further, the upper end of the stored item S is inserted into the first through hole 131. At this time, each side of the octagonal portion of the first through hole 131 comes into contact with the outer surface of the upper end of the stored item S. That is, the upper end of the stored item S is fitted into the octagonal portion of the first through hole 131. Therefore, the upper end of the stored item S is stably held by the peripheral portion of the first through hole 131, that is, the rotation of the upper end of the stored item S can be suppressed.

In addition, since the upper end of the stored item S is held by each side of the octagonal portion, the diameter of the circle inscribed in the octagonal portion of the first through hole 131 and the outer diameter of the stored item S are Insertion is possible even in different cases. For example, when the outer diameter of the upper end of the stored item S is larger than the diameter of the circle inscribed in the octagonal portion of the first through hole 131, the stored item S deforms the octagonal portion of the first through hole 131. Can be inserted. Accordingly, the upper end portion of the stored item S is firmly held by the peripheral edge portion of the first through hole 131. On the contrary, when the outer diameter of the upper end of the stored item S is smaller than the diameter of the circle inscribed in the octagonal portion of the first through hole 131, the first through hole 131 includes the octagonal portion, and thus the octagonal shape is formed. The storage item S can be supported by a plurality of sides of the portion. Therefore, even if there is an error in the outer diameter of the upper end portion of the stored item S and the diameter of the circle inscribed in the first through hole 131, the edge portion of the first through hole 131 causes the lower end portion of the stored item S to move. Hold firmly.

As a result, as shown in FIG. 9, even when three stored items S are stored, the stored items S are held inside the storage box 100. The shape and size of the octagonal portion of the first through hole 131 and the shape and size of the decagonal portion of the second through hole 231 are determined according to the shape of the stored item S.

Further, when the upper end of the stored item S is inserted, the octagonal portion may be formed so as to be easily deformed by the stored item S. As such a shape, for example, as the shape of the octagonal portion of the first through hole 131, a shape in which each side of the octagonal portion is convexly curved inward can be cited. In this way, by bending each side of the octagonal portion inwardly, the octagonal portion of the first through hole 131 is easily deformed when the storage item S is inserted. Note that the shape is not limited to the curved shape, and may be a configuration in which it is convexly bent inward, or may be a shape in which a part thereof projects in a convex shape. It is possible to widely adopt a shape in which the octagonal portion is easily deformed by inserting the storage item S.

As a result, the upper end of the stored item S is more strongly held in the first through hole 131, and the effect of suppressing the rotation of the stored item S is further enhanced. The curved sides may be all sides or some sides of the octagonal portion of the first through hole 131. Further, the side of the decagonal portion of the second through hole 231 may also be curved inwardly convex like the side of the octagonal portion of the first through hole 131. By configuring the second through hole 231 in this way, the lower end portion of the stored item S is also firmly held.

The stored item S is held by fitting the upper end portion into the first through hole 131 and the lower end portion into the second through hole 231. As described above, the stored items S stored in the storage box 100 are held while being prevented from rotating. For example, the outer diameter of the upper end of the stored item S is smaller than the diameter of the circle inscribed in the octagonal portion of the first through hole 131, or the circle inscribed in the decagonal portion of the second through hole 231 is inscribed. The outer diameter of the lower end of the stored item S may be smaller than the diameter. Even in this case, since the other is configured to firmly hold the stored item S, the stored item S stored in the storage section 60 is held stably, that is, in a state in which the rotation is suppressed.

Further, as described above, by holding the upper end of the stored item S at the peripheral edge of the first through hole 131 and the lower end of the stored item S at the peripheral edge of the second through hole 231, the packaging container A Even if the orientation of the storage container 100 is changed or the packaging container A is moved, the orientation of the storage object S in the storage box 100 does not easily change.

For example, a pattern (not shown) may be provided on the trunk of the stored item S. By storing the symbol of the stored item S in a predetermined direction (for example, facing upward) when storing in the storage box 100, even if the packaging container A (the storage box 100) is moved, the symbol of the stored item S is stored. The orientation in box 100 is maintained. The design may be directly formed on the surface of the storage item S, or a sheet-shaped member on which the design is formed by printing or the like may be attached to the surface of the storage item S.

In the storage box 100, by inserting the storage item in the through hole formed in the inner surface plate, the movement of the storage item S can be suppressed without using a fixing member attached to the bottom portion. That is, the storage box 100 is configured of one paper sheet Ps and can stably hold the storage item S. Then, the stored item S includes a side edge portion of the first through hole 131 of the first inner surface plate 13 of the first side wall 1, a side edge portion and a bottom portion of the second through hole 231 of the second inner surface plate 23 of the second side wall 2. Held at 101. That is, the storage box 100 is supported by the three walls. Therefore, the stored item S is stably held in the storage box 100 as compared with the case where it is held by using a fixing member attached to the bottom.

In the present embodiment, as the stored item S, a cylindrical container having different upper and lower outer diameters is described as an example. Therefore, the first through hole 131 and the second through hole 231 have different sizes. However, the present invention is not limited to this, and may be a cylindrical container having a constant outer diameter in the axial direction. In this case, the first through hole 131 and the second through hole 231 may have the same size and shape.

(4. Operation of the storage box 100)
Next, other operations of the storage box 100 of the packaging container A according to the present embodiment will be described with reference to the drawings. FIG. 10 is a perspective view showing a state in which the first side wall 1 of the storage box 100 is tilted. FIG. 11 is a perspective view showing a state in which the first side wall 1 is tilted with the stored item S stored therein.

As shown in FIGS. 7 and 8, the second side surface flap 24 has a chamfered rectangular shape, and its upper end is in contact with the third upper surface plate 32 and the fourth upper surface plate 42. Further, the folded portion 25 is inserted inside the third side wall 3 and the fourth side wall 4 in a folded state. Then, the third upper surface plate 32 and the fourth upper surface plate 42 overlap with a part of the convex portion 221 of the second upper surface plate 22. Therefore, the second side wall 2 is firmly connected to the third side wall 3 and the fourth side wall 4. That is, in the storage box 100, the second side wall 2, the third side wall 3, and the fourth side wall 4 are strong U-shaped structures forming a part of the peripheral wall 102.

On the other hand, the first outer side flap 141 and the first inner side flap 142 of the first side surface flap 14 are inclined downward as the upper end goes to the free end. As shown in FIGS. 7 and 8, there is a gap between the upper ends of the first outer flap 141 and the first inner flap 142 on the front side and the third upper surface plate 32. There is a gap between the upper ends of the first outer flap 141 and the first inner flap 142 on the rear side and the fourth upper surface plate 42. This gap becomes larger toward the free ends of the first outer flap 141 and the first inner flap 142.

Therefore, in the storage box 100, even if the upper ends of the first side walls 1 are tilted toward the outer peripheral side, the upper ends of the first outer flap 141 and the first inner flap 142 contact the third upper surface plate 32 and the fourth upper surface plate 42. It is hard to be restricted by movement. That is, the upper end of the first side wall 1 can be tilted toward the outer peripheral side (see FIG. 10). By adjusting the shapes of the upper ends of the first outer flap 141 and the first inner flap 142, when the first side wall 1 is tilted by a certain angle, further tilting can be restricted.

As shown in FIG. 10, in the storage box 100, the upper end of the first side wall 1 is tilted toward the outer peripheral side while maintaining the U-shaped connection of the second side wall 2, the third side wall 3, and the fourth side wall 4. be able to. As shown in FIG. 11, by tilting the upper end of the first side wall 1 toward the outer peripheral side, the fitting between the upper end of the stored item S and the first through hole 131 is released. Thereby, the stored item S can be easily taken out from the storage box 100. Since the stored item S is supported by the bottom portion 101, it is easy to disengage the upper end portion of the stored item S from the first through hole 131. Also in this respect, the convenience for the user is high.

In addition, when the first side wall 1 is returned from the tilted state to the upright state (the state in which the first through hole 131 holds the upper end portion of the stored item S), the locking claws 331 of the third inner surface plate 33 and The locking claws 431 of the fourth inner surface plate 43 are inserted into the locking holes 132 provided at both ends of the first inner surface plate 13. Thereby, the first side wall 1 is held in an upright state. That is, the locking of the locking claws 331, 431 and the locking hole 132 restricts the free tilting of the first side wall 1. For example, when a certain force or more acts on the first side wall 1 in the tilting direction, the engagement between the locking claws 331 and 431 and the locking hole 132 is released, and the first side wall 1 is tilted. In addition, the first side wall 1 may be tilted after the locking claws 331 and 431 are deformed (flexed) so as to be easily disengaged from the locking hole 132.

(5. About lid material 200)
Details of the lid member 200 will be described with reference to the drawings. FIG. 12 is a perspective view of the lid member 200 provided in the packaging container A shown in FIG. The lid member 200 includes a bottom surface portion 201, a top surface portion 202, and a pair of outer fitting plates 203. The bottom surface portion 201 and the top surface portion 202 have a rectangular shape. The bottom surface portion 201 and the top surface portion 202 have substantially the same shape as the bottom portion 101 of the storage box 100. The bottom surface portion 201 and the top surface portion 202 are arranged vertically side by side, and the long sides corresponding to the top and bottom are connected to the outer fitting plate 203, respectively.

The lid member 200 includes a bottom surface portion 201, an upper surface portion 202, and a pair of outer fitting plates 203, and is formed in a tubular shape having an opening in the front and rear. The storage box 100 is inserted from the front or rear end through the front or rear opening to store the storage box 100 in the lid member 200. Note that one of the openings may be closed. With this configuration, it is possible to prevent the storage box 100 stored in the lid member 200 from falling off. As shown in FIGS. 1 and 12, the upper surface portion 202 is provided with a window portion 204 which is a through hole.

Note that the lid material 200 is not limited to this shape. For example, a lid member 300 as shown in FIG. 13 may be used. FIG. 13 is a perspective view of another example of the lid member 300 as seen from below. The lid member 300 shown in FIG. 6 includes an upper surface portion 301, an outer fitting plate 302, and a window portion 303. The upper surface portion 301 has a rectangular shape. The outer fitting plate 302 is a rectangular parallelepiped tubular body connected to each side of the upper surface portion 301. The window portion 303 is a through hole provided in the upper surface portion 301. That is, the lid member 300 has a cylindrical shape with a lid having an opening at the bottom. By inserting the storage box 100 into the opening from the upper surface side, the upper opening of the storage box 100 is closed with the lid member 300.

The lid member 200 (300) is attached in a state where the storage item S is stored in the storage box 100. When the lid member 200 is attached to the storage box 100, the user can confirm the stored item S stored inside through the window portion 204 (303). The window portion 204 (303) may be a through hole as it is, or a transparent resin film that covers the window portion 204 (303) may be attached. Alternatively, a partially visible member such as a mesh may be attached.

As described above, the stored item S may have a pattern formed on its surface. The pattern on the surface of the stored item S stored in the packaging container A is visually recognized by the user through the window portion 204 (303) of the lid member 200 (300). For example, in the packaging container A, a pattern (not shown) arranged around the window portion 204 (303) of the lid member 200 (300) and a pattern arranged in the stored item S and/or the stored item S are included. In some cases, one design (designated as a design for distinction from the design formed on each member) may be configured.

For example, in the packaging container A, it is assumed that the lid member 200 (300), the stored item S, and/or a design that is a pattern arranged on the stored item S is formed. In the packaging container A, the rotation of the stored item S is suppressed even when the packaging container A is transported, displayed on a product shelf, or the like. Therefore, in the packaging container A after the movement, the pattern formed before the movement is less likely to be disturbed. Therefore, by using the packaging container A, the user recognizes the pattern formed by the seller from the storage box 100, the lid member 200 (300) and the storage item S while being displayed on a shelf for sale or the like. It is possible to That is, by using the packaging container A, it is possible to enhance the appealing effect of the product (the stored item S) to the user (purchaser). Further, since the design is not easily disturbed even after purchase, the design of the packaging container A can be used for decoration in a living space of a user such as a living room or an office. That is, by using the packaging container A, the stored items S can be reliably held without impairing the design.

Further, when the lid member 200 (300) is attached to the storage box 100, the first side wall 1 is fitted onto the outer fitting plate 203 (302). Thereby, when the lid member 200 (300) is attached to the storage box 100, the tilting of the first side wall 1 is suppressed. That is, when the lid member 200 (300) is attached to the storage box 100, in the storage box 100, by the first through hole 131 of the first inner face plate 13 and the second through hole 231 of the second inner face plate 23, The stored item S is stably held. Further, by removing the lid member 200 (300), the storage box 100 can tilt the upper portion of the first side wall 1 outward. This makes it easy to take out the stored item S.

As described above, by using the packaging container A of the present embodiment, it is not necessary to arrange a holding member in the storage portion 60 when the storage item S is stored. Further, the stored item S is held so that the stored item S does not shift or move (rotate), that is, in a stable state. Further, by tilting the upper end of the first side wall 1 toward the outer peripheral side, the holding of the upper end portion of the stored item S by the first through hole 131 is released. Thereby, the stored item S can be easily taken out. This can prevent the stored item S from moving inside the packaging container A during transportation, for example. As a result, it is possible to suppress deterioration of the stored items S and the like. Further, the stored items S can be taken out from the packaging container A by tilting the first side wall 1. From these things, it is possible to improve the convenience of the user.

In the packaging container A of the present embodiment, the first side wall 1 is tilted, but the present invention is not limited to this. For example, when the first side wall 1 is not tilted, the first side surface flap 14 may have the same shape as the second side surface flap 24. Further, a folding portion having the same configuration as the folding portion 25 may be provided between the first outer surface plate 11 and the third outer surface plate 31 and the fourth outer surface plate 41. Further, the lid member 200 (300) may be attached as needed. When the lid material 200 (300) is unnecessary, the packaging container A is configured by the storage box 100 alone.

(6. Modification 1)
A modified example of the present embodiment will be described with reference to the drawings. FIG. 14 is a development view of another example of the storage box 100 according to the present embodiment. FIG. 14 is a paper sheet Ps before the storage box 100 is assembled. The storage box 100 shown in FIG. 14 has the same configuration as the paper sheet Ps shown in FIG. 4 except that the shapes of the first through hole 134 and the second through hole 233 are different. Therefore, the substantially same parts of the paper sheet Ps of FIG. 14 as the paper sheet Ps shown in FIG. 4 are denoted by the same reference numerals.

The storage box 100 of the present embodiment is configured to store a cylindrical storage item S. Therefore, as shown in FIG. 14, the first through hole 134 and the second through hole 233 may have a circular shape (arc shape) instead of the octagonal shape and/or the decagonal shape. By configuring the first through hole 134 and the second through hole 233 to include a circular shape (arc shape), stress is less likely to be concentrated at the edge portions of the first through hole 134 and the second through hole 233, and collapse Hateful. As such a storage item S to be stored in the storage box 100 having the first through hole 134 and the second through hole 233 including the circular portion, for example, a pattern that does not change or does not substantially change even when rotated. An example is a stored item S in which is formed. Further, it may be a stored item S whose pattern may be changed by rotating.

(7. Modification 2)
The storage box 100 according to the present embodiment has been described by taking as an example a configuration in which a cylindrical shape having a circular cross section cut along a plane orthogonal to the central axis is stored as the storage object S. However, the stored item S is not limited to the cylindrical shape. For example, the shape of the cross section cut along the plane orthogonal to the central axis may be a configuration that accommodates a storage item other than a circle such as a polygon such as a triangle, a quadrangle, and a hexagon, or an ellipse. In this case, the first through hole and the second through hole may have a shape corresponding to the sectional shape of the stored item. Further, the stored item may have a flexible outer surface, that is, a deformable structure, such as a pillow bag-shaped packaging bag containing the contents. In this case, the first through hole and the second through hole have a shape that can be reliably fixed according to the stored item.

The packaging container A described above is formed by cutting and bending a paper sheet. However, it is not limited to this. For example, a resin sheet may be used instead of the paper sheet.

The length from the boundary between the first bottom surface flap 15 and the first inner surface plate 13 to the free end is longer than the length from the boundary between the second bottom surface flap 26 and the second inner surface plate 23 to the free end. That is, the first bottom surface flap 15 has a larger area than the second bottom surface flap 26.

In the above-described embodiment, the first bottom surface flap 15 and the second bottom surface flap 26 are bonded. On the other hand, the first bottom surface flap 15 and the second bottom surface flap 26 may not be adhered. In this case, by increasing the area of the first bottom surface flap 15, the frictional force between the bottom wall 5 and the bottom surface cover 44 can be increased.

Thereby, when the first side wall 1 is tilted in a state where the first bottom surface flap 15 is not adhered, the displacement of the first bottom surface flap 15 can be suppressed. This makes it easier to return the original shape after tilting the first side wall 1.

Various technical features disclosed in this specification can be variously modified without departing from the gist of the technical creation. In addition, the plurality of embodiments and modifications shown in the present specification may be combined and implemented within a possible range.

The packaging container A having the above-described configuration includes a storage portion 60 having a pair of first side wall 1 and second side wall 2 facing each other and a peripheral wall 102 standing on the bottom wall 5 and having an open top surface. The first side wall 1 and the second side wall 2 are outer surface plates 11 and 21 that are bent upward from the bottom wall 5, and upper surface plates 12 and 22 that are bent inward from the upper ends of the outer surface plates 11 and 21. Inner surface plates 13 and 23 bent downward from inner ends of the upper surface plates 12 and 22. The inner surface plate 13 and the inner surface plate 23 that face each other include through holes 131 and 231 that hold the stored items S by fitting.

According to this configuration, the stored item S can be held without the holding member for holding the stored item S inside the storage section 60. Therefore, the materials used can be reduced, the cost can be reduced, and the weight of the packaging container A itself can be reduced. Further, since the two places (both ends) of the stored item S are fitted into the through holes 131, 231, the stored item S can be stably held. Therefore, even when the stored item S is transported in a stored state, the stored item S is unlikely to shift or move. Therefore, it is possible to suppress deformation and deterioration of the stored items S. Furthermore, since the stored item S can be held only by fitting it into the through holes 131 and 231, the stored item S can be easily attached and detached. Therefore, it is possible to improve the convenience of the user.

In the above configuration, the first side wall 1 may be capable of tilting the upper end toward the outer peripheral side around the lower end. With this configuration, it is possible to easily remove the holding of the stored item S by the through hole 131 provided on the first side wall 1 side. As a result, the storage item S can be easily attached and detached, and the convenience of the user can be further enhanced.

In the above configuration, at least one of the outer surface plate 11 and the inner surface plate 13 of the first side wall 1 includes the side surface flap 141 (142) bent inward from the side end. The peripheral wall 3 (4) adjacent to the first side wall 1 is formed by bending so that the side surface flap 141 (142) can be inserted. The upper end of the side flap 141 (142) inclines downward toward the free end. With this configuration, since the side surface flaps 141 (142) of the first side wall 1 are housed in the peripheral wall 3 (4), it is possible to increase the strength of the corner portion of the packaging container. Further, the first side wall 1 can be easily tilted to the outer peripheral side. Therefore, the strength of the packaging container A can be increased, and the stored items S can be easily attached and detached, and the convenience of the user can be further increased.

The through hole 131 (231) may have a shape including a part of a polygon with which the stored item S can be inscribed. With this configuration, the through hole 131 (231) can hold the outer surface of the stored item S at a plurality of points. Further, at least one side of the polygon of the through hole 131 (231) provided in at least one of the inner surface plate 13 of the first side wall 1 and the inner surface plate 23 of the second side wall 2 is curved in a convex shape toward the inside. Good. Thereby, when inserting the storage item S, the polygonal side portions can be deformed, and the storage item S is more firmly held.

In the above configuration, a lid member 200 that covers the upper surface of the storage section 60 is further provided. The lid member 200 includes at least an outer fitting plate 203 that is fitted onto the outer surface plate 11 of the first side wall 1. With this configuration, the outer fitting plate 203 presses the outer surface plate 11 of the first side wall 1 when the lid member 200 is attached. Therefore, even when vibration or force acts on the packaging container A during transportation or the like, tilting of the first side wall 1 toward the outer peripheral side is suppressed. As a result, the packaging container A can prevent the stored items S from being displaced or moved during transportation.

In the above configuration, the bottom surface flap 15 (26) bent inward from the lower end of the inner surface plate 13 (23) is further provided. The length of the bottom surface flap 15 connected to the first side wall 1 in the direction in which the first side wall 1 and the second side wall 2 face each other may be longer than that of the bottom surface flap 26 connected to the second side wall 2.

In the above configuration, the bottom surface flap 15 (26) bent inward from the lower end of the inner surface plate 13 (23) and the bottom surface flap 15 (26) formed by the notch 133 (232) provided in the inner surface plate 13 (23). 26), and a support piece 16 (27) that projects outward from the outer surface plate 11 (21) and abuts the inner surface of the outer surface plate 11 (21). With such a configuration, the outer surface plate 11 (21) and the inner surface plate 13 (23) are connected at their upper ends by the upper surface plate 12 (22) and at their lower ends by the support pieces 16 (27) at regular intervals. Be supported to make. Therefore, the space between the outer surface plate 11 (21) and the inner surface plate 13 (23) can be kept constant. As a result, the length of the portion of the stored item S that protrudes from the through hole 131 (231) can be kept constant, and the stored item S can be held more stably.

In the above structure, the notch 133 (232) may extend from the fold line of the boundary between the bottom surface flap 15 (26) and the inner surface plate 13 (23) to form the edge of the through hole 131 (231). With this configuration, the support piece 16 (27) and the bottom flap 15 (26) can be formed on the same surface. Therefore, by bending the bottom surface flap 15 (26) along a fold line provided at the boundary between the lower end of the inner surface plate 13 (23) and the bottom surface flap 15 (26), the support piece 16 (27) is moved to the outer surface plate 11. It can be projected to the (21) side. This makes it possible to reduce the assembly work. Further, the amount of material can be reduced as compared with the case where the support piece 16 (27) is separately provided.

According to the present invention, it can be used as a packaging container for stably storing a storage item having a certain length.
