Description

[Technical Field]

[0001] This disclosure relates to a packaging box for fresh flowers used in packaging fresh flowers. [Background technology]

[0002] A cardboard packaging box for fresh flowers, such as cut flowers, is known for its use during transportation. This packaging box is equipped with a support that holds the stem portion of the fresh flowers at a certain distance from the back of the box (see, for example, Patent Document 1). In the packaging box for fresh flowers described in Patent Document 1, the opening of the soft resin bag into which the stem portion of the cut flowers is inserted is fixed by the support. Therefore, even if the packaging box is turned on its side for storing or removing cut flowers, the liquid such as water injected into the soft resin bag is prevented from leaking out. This makes the packaging of fresh flowers easier. [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Utility Model Registration No. 3097762 Gazette [Overview of the Initiative] [Problems that the invention aims to solve]

[0004] The support base for the flower packaging box described in Patent Document 1 above is formed by folding a flap (folded plate) that extends from the bottom plate at a predetermined location. The folded flap (folded plate) is fixed in a folded state by inserting a locking piece formed on its leading edge into a locking hole formed at a predetermined location on the flap.

[0005] While this conventional packaging box for fresh flowers can be fixed in place by forming a support base without requiring any additional parts, the process of forming that support base is complicated, time-consuming, and requires a significant amount of time to assemble.

[0006] This disclosure was made to solve the above-mentioned problems and discloses an example of a packaging box for fresh flowers that can form a base for supporting fresh flowers using a simple procedure. [Means for solving the problem]

[0007] To achieve the above objectives, this disclosure provides the following means: The flower packaging box of this disclosure is a rectangular parallelepiped-shaped flower packaging box used for packaging fresh flowers, the flower packaging box having a cylindrical body portion having a front opening which is the front opening through which the fresh flowers are put in and taken out, and a rear opening which is the rear opening opposite to the front, a lid flap which covers at least a part of the front opening, a rear inner flap which covers at least a part of the rear opening, and a rear outer flap which covers at least a part of the rear opening, and a base portion which is arranged inside the body portion and supports at least a part of the fresh flowers at a predetermined distance away from the rear opening toward the front, the body portion being composed of an upper surface portion and a bottom surface portion which face each other in the vertical direction which is the longitudinal direction of the rectangular parallelepiped shape, and a first side portion and a second side portion which face each other in the left-right direction which intersects the vertical direction, the rear inner flap having an upper inner flap which extends from the upper surface portion and a lower inner flap which extends from the bottom portion The rear outer flap has a first rear outer flap extending from the first side portion and a second rear outer flap extending from the second side portion, the lower inner flap has a base portion on the side of the bottom portion and a support portion extending from the end of the base portion in a direction away from the bottom portion, a middle fold is provided at the boundary between the base portion and the support portion in the direction in which the boundary between the bottom portion and the lower inner flap extends, a slit is formed on the side of the first side portion of the lower inner flap that extends linearly across the base portion and the support portion, a bent piece is provided in the portion of the first rear outer flap corresponding to the slit, and the base portion is formed by inserting the bent piece, which is raised toward the first side portion, into the slit of the lower inner flap, which is bent at the middle fold so that the support portion is perpendicular to the base portion.

[0008] According to the flower packaging box of this disclosure, the rear inner flap is folded up along the central fold, and a folded piece is inserted into the slit portion of the folded rear inner flap to form a base. In other words, the base of the flower packaging box can be assembled with simple work.

[0009] In the above, the support portion has a front fold, which is a fold formed at a predetermined distance away from the middle fold in the direction in which the rear inner flap extends, an intermediate portion on the base side of the front fold, and a front portion on the side of the front fold, and it is preferable that the base portion is formed by the front fold being bent toward the upper surface portion at the front fold so as to be perpendicular to the intermediate portion which is arranged perpendicular to the base portion.

[0010] By doing so, the front portion is positioned approximately parallel to the rear surface that closes the rear opening of the flower packaging box. In other words, the front portion is positioned approximately parallel to the rear outer flap that closes the rear opening. That is, a flower packaging box is formed that has a base portion with a front portion that supports the stem portion of the flower being packaged.

[0011] In the above, it is preferable that the second side portion is formed with a first locking portion which prevents the intermediate portion, which is arranged perpendicular to the base portion, from falling toward the upper portion, and a second locking portion which prevents the base portion, which is arranged perpendicular to the bottom portion, from moving toward the front opening.

[0012] By doing this, it is possible to prevent the middle section of the base from tipping upwards with simple work. It also prevents the base section from moving forward. In other words, it prevents the base from moving from its designated position.

[0013] In the above, it is preferable that the bent piece is a portion partitioned by a set of cuts extending from the edge of the first rear outer flap toward the first side surface portion.

[0014] By doing so, the pedestal portion of the flower arrangement packaging box can be assembled with simple operations. Also, the operation of forming the bent piece can be easily performed.

Effect of the Invention

[0015] According to the flower arrangement packaging box of the present disclosure, it is possible to provide a flower arrangement packaging box capable of forming a pedestal portion for supporting a flower arrangement by a simple procedure.

Mode for Carrying Out the Invention

[0017] An example of a fresh flower packaging box according to one embodiment of this disclosure will be described with reference to Figures 1 to 9. In the following description, directions such as front and back, left and right, and up and down will refer to the directions shown in the figures unless otherwise specified. The side of the fresh flower packaging box in which the fresh flowers are contained will be referred to as the inside, and the opposite side will be referred to as the outside.

[0018] At least one of the components or parts described with a reference numeral is provided, unless otherwise specified, such as "one." In other words, if there is no such specification, such as "one," two or more of the component may be provided.

[0019] In the following explanation, "approximately the same length" or "approximately the same distance" includes not only cases where two or more lengths or distances are identical, but also cases where their lengths differ to an extent that does not hinder the assembly of the packaging box 1 or the base 30. For example, when distance X (or length X) is approximately the same as distance Y (or length Y), this includes not only cases where distance X and distance Y are exactly the same length, but also cases where, considering factors such as the thickness of the sheet material and the dimensions when the sheet material is bent, distance X is slightly shorter than distance Y, or distance X is slightly longer than distance Y.

[0020] 1. Description of the packaging box 1 for fresh flowers The fresh flower packaging box 1 is a rectangular cardboard packaging box used to package fresh flowers, such as cut flowers, during transportation. Hereafter, the fresh flower packaging box 1 will also be referred to simply as "packaging box 1".

[0021] Packaging box 1 is used with its rectangular parallelepiped shape oriented so that its longest side is the vertical direction. That is, when packaging box 1 is transported, the side with the flowers of the packaged fresh flowers faces upwards, and the side with the stems faces downwards (see Figure 9).

[0022] The packaging box 1 mainly consists of a main body 5, a lid flap 4, a rear flap 6, and a base 30 (see Figure 1, etc.). The main body 5 is a cylindrical part having a rectangular front opening 2 and a rear opening 3, and is formed by connecting an upper surface 11, a bottom surface 12, a left side surface 13B, and a right side surface 13A (see Figure 1). The upper surface 11 is the upper surface (top surface) of the packaging box 1 when it is being transported, etc. The bottom surface 12 is the lower surface (floor surface) of the packaging box 1 when it is being transported, etc.

[0023] The lid flap 4 is a front (lid side) flap that closes the front opening 2, which is the opening at the front of the main body 5. The lid flap 4 consists of outer lid flaps 15A and 15B and inner lid flaps 16A and 16B, which will be described in detail later. When fresh flowers are packaged, each of the lid flaps 4 is folded inward at the boundary with the main body 5 so as to be approximately perpendicular to the main body 5, and positioned to close the front opening 2.

[0024] The rear flap 6 is a rear flap that closes the rear opening 3, which is the opening at the rear of the main body 5. Figure 1 shows the rear opening 3 closed by the rear flap 6. The rear flap 6 has a rear inner flap 19 and a rear outer flap 17, which will be described in detail later. The rear inner flap 19 has a lower inner flap 19A and an upper inner flap 19B, which will be described in detail later (see Figures 2 and 3). The rear outer flap 17 has a right rear outer flap 17A and a left rear outer flap 17B, which will be described in detail later (see Figures 2 and 3). When fresh flowers are packaged, each of the rear flaps 6 is folded inward at the boundary with the main body 5 so as to be approximately perpendicular to the main body 5, and positioned to close the rear opening 3.

[0025] The base portion 30 is the part inside the main body portion 5 that supports the packaged fresh flowers F. The base portion 30 is positioned at a predetermined distance d from the rear opening 3 and is configured to support a portion of the stem of the fresh flowers F (see Figure 9, etc.). The base portion 30 is formed by folding the lower inner flap 19A, which will be described in detail later, at a predetermined location. Details of the base portion 30 will be described later.

[0026] 2. Description of sheet materials A and B In the following, the sheet materials A and B that make up packaging box 1 will be explained, mainly with reference to Figures 2 and 3. In Figures 2 and 3, the side of the paper on which sheet materials A and B are printed will be referred to as the front side or surface, and the opposite side will be referred to as the back side or reverse side.

[0027] Packaging box 1 is formed by folding a corrugated cardboard sheet that has been shaped into a predetermined form. Specifically, packaging box 1 is assembled by joining sheet material A and sheet material B into a cylindrical shape and folding them according to folds formed at predetermined locations.

[0028] Sheet material A is a corrugated cardboard sheet formed into the shape shown in Figure 2. Sheet material B is a corrugated cardboard sheet formed into the shape shown in Figure 3.

[0029] 2-1 Explanation of Sheet Material A As shown in Figure 2, sheet material A has a long shape in the direction intersecting the front-to-back direction. Hereafter, the direction intersecting the front-to-back direction will also be referred to as the "width direction". In sheet material A, the bottom portion 12 and the right side portion 13A are arranged side by side in the width direction. The bottom portion 12 and the right side portion 13A are connected at the boundary 26a between them. A fold is formed at the boundary 26a.

[0030] An adhesive tab 14A is attached to the bottom portion 12 on the side opposite to the right side portion 13A. A fold is formed at the boundary 25a between the bottom portion 12 and the adhesive tab 14A. The right side portion 13A is an example of a second side portion.

[0031] An outer flap 15A is connected to the front side of the right side portion 13A (see Figure 2). A fold is formed on the edge 23a between the right side portion 13A and the outer flap 15A. A right rear outer flap 17A is connected to the rear side of the right side portion 13A (see Figure 2). A fold is formed on the edge 24a between the right side portion 13A and the right rear outer flap 17A. The right rear outer flap 17A is an example of a second rear outer flap.

[0032] The right side portion 13A is formed so that its length in the front-to-back direction is the same as the length of the bottom portion 12 in the front-to-back direction. The right rear outer flap 17A is also formed so that its length in the front-to-back direction is the same as the widthwise length of the bottom portion 12.

[0033] An inner lid flap 16A is connected to the front side of the bottom portion 12. A fold is formed on the edge 21a between the bottom portion 12 and the inner lid flap 16A. The inner lid flap 16A is formed so that its length in the front-to-back direction is the same as the length of the outer lid flap 15A in the front-to-back direction. A lower inner flap 19A is connected to the rear side of the bottom portion 12. A fold is formed on the edge 22a between the bottom portion 12 and the lower inner flap 19A.

[0034] Adhesive tabs 14c are connected to the front and back sides of adhesive tab 14A, respectively. A fold is formed between adhesive tab 14A and the front adhesive tab 14c. Also, a fold is formed between adhesive tab 14A and the back adhesive tab 14c.

[0035] A middle fold 33 is formed near the approximate center in the front-to-back direction of the lower inner flap 19A, at a distance e1 from the edge 22a towards the rear. The middle fold 33 is a fold that extends parallel to the direction in which the edge 22a extends. Furthermore, a front fold 35 is formed at a predetermined distance d from the middle fold 33 towards the rear. The front fold 35 is a fold that extends parallel to the middle fold 33.

[0036] The lower inner flap 19A is divided into a base portion 31, an intermediate portion 36, and a tip portion 37 by the middle fold 33 and the tip fold 35. The portion of the lower inner flap 19A closest to the bottom surface 12, between the edge 22a and the middle fold 33, is the base portion 31. Hereafter, the side closer to the bottom surface 12 will also be referred to as the "base side," and the side further away from the bottom surface 12 will also be referred to as the "tip side."

[0037] The portion of the lower inner flap 19A that is ahead of the base portion 31 and between the middle fold 33 and the front fold 35 is the intermediate portion 36. The portion of the lower inner flap 19A that is ahead of the front fold 35 is the front portion 37. In the following description, the portion having the intermediate portion 36 and the front portion 37 will also be referred to as the "support portion 32". That is, the intermediate portion 36 and the front portion 37 will also be referred to collectively as the "support portion 32".

[0038] On the side of the lower inner flap 19A closest to the adhesive margin 14A, a slit 34 is formed that spans the base side portion 31 and the support portion 32 and extends linearly in the front-rear direction. In other words, when the packaging box 1 is assembled, a linear slit 34 is formed on the portion of the lower inner flap 19A that is on the side of the left side portion 13B (the side closest to the left side portion 13B). More specifically, a slit 34 is formed at a distance f1 in the width direction from the end edge 70 of the lower inner flap 19A, extending linearly in the front-rear direction, spanning the base side portion 31 and the support portion 32. The end edge 70 is the side of the lower inner flap 19A opposite to the right rear outer flap 17A.

[0039] The slit 34 is an elongated through-hole cut out of the sheet material A. The slit 34 has a width sufficient to allow the bent piece 41, which will be described in detail later, to be inserted. Specifically, the slit 34 is a portion cut out in a long shape in the front-to-back direction, with a width approximately the same as the thickness of the sheet material B that constitutes the bent piece 41. For example, the slit 34 is formed when the sheet material B is punched out using an elongated punching die that has a width approximately the same as the thickness of the sheet material B.

[0040] In the base portion 31, the distance between the front end 34a and the edge 22a of the slit 34 is distance L.11 It is formed in such a way. Also, the distance between the end portion 34a and the middle fold 33 is distance L 12 It is formed in such a way. Furthermore, in the support portion 32 (intermediate portion 36), the distance between the front end 34b (rear side in Figure 2) and the middle fold 33 is distance L. 13 It is formed in such a way (see Figure 2).

[0041] In the base portion 31, a semicircular notch 34c that bulges in the width direction is formed in the slit 34. This notch 34c is to prevent the portion punched out by the punching die from remaining in the sheet material A when the slit 34 is formed by the punching die. In other words, the formation of the notch 34c makes it easier for the portion punched out by the punching die to separate from the sheet material A. That is, when forming the sheet material A, the portion punched out to form the slit 34 is prevented from remaining in the sheet material A, making the sheet material A formation process easier.

[0042] The base portion 31 and the intermediate portion 36 have the same length in the width direction. On the other hand, the width direction length of the front portion 37 is shorter than that of the base portion 31 and the intermediate portion 36. The side of the intermediate portion 36 opposite to the central fold 33 has a recessed shape toward the base portion 31 around the portion to which the front portion 37 extends. In other words, the intermediate portion 36 is formed such that its length in the front-to-back direction gradually decreases from the end of the intermediate portion 36 in the width direction toward the portion to which the front portion 37 extends.

[0043] On both sides of the front portion 37, a pair of protrusions 38 are formed, projecting in the width direction. The protrusions 38 are the parts to which a rubber band or other material used to secure the fresh flowers F is attached when packaging the fresh flowers F. The base side (the side of the front portion 37) of each protrusion 38 is formed such that its length in the front-to-back direction is shorter than its front side (the side in the direction from which the protrusion 38 protrudes).

[0044] A roughly U-shaped notch 39 is formed at the tip of the front portion 37. The notch 39 is the part that secures the opening of the soft resin bag G into which the stem portion of the fresh flower F is inserted. A liquid such as water for the fresh flower F is sealed inside this soft resin bag G along with the stem portion.

[0045] Indentation pieces 27 and 28 are formed on the right side surface 13A, on the side closer to the bottom surface 12. Indentation piece 27 is a roughly square portion enclosed by sides 27a, 27b, 27c, and 27d. Sides 27a and 27c extend parallel to edge 24a, and sides 27b and 27d extend parallel to boundary 26a. Side 27a is the side further from edge 24a than side 27c, and side 27d is the side further from boundary 26a than side 27b. Cuts are formed in the parts of sides 27a, 27b, and 27c, and a fold is formed in the part of side 27d. Hereafter, side 27d will also be referred to as "fold 27d". In other words, the indentation piece 27 is the portion enclosed by the U-shaped cuts formed on sides 27a, 27b, and 27c, and the fold 27d connecting the ends of sides 27a and 27c.

[0046] The pressed-in piece 28 is a roughly square portion enclosed by sides 28a, 28b, 28c, and 28d. Sides 28a and 28c extend parallel to the boundary 26a, and sides 28b and 28d extend parallel to the edge 24a. Side 28a is the side closer to the boundary 26a than side 28c, and side 28d is the side closer to the edge 24a than side 28b. Cuts are formed in the portions of sides 28a, 28b, and 28c, and a fold is formed in the portion of side 28d. Hereafter, side 28d will also be referred to as "fold 28d". In other words, the pressed-in piece 28 is the portion enclosed by the U-shaped cuts formed in sides 28a, 28b, and 28c, and the fold 28d connecting the ends of sides 28a and 28c.

[0047] The indentation piece 27 is formed at a position corresponding to the intermediate portion 36 of the assembled base portion 30. Specifically, the edge 27c of the indentation piece 27 is formed to be in approximately the same position as the edge 24a. Preferably, the edge 27c is formed to be shifted forward (towards the front opening 2) by a dimension equal to the thickness of the sheet material B compared to the edge 24a. Also, the fold 27d is formed at a distance e2 in the width direction from the boundary 26a. Preferably, the distance e2 is approximately the same length as the aforementioned distance e1, but it may be shorter than the distance e1. That is, the indentation piece 27 may be formed such that the fold 27d is closer to the boundary 26a than the position at a distance e1 in the width direction from the boundary 26a. The indentation piece 27 is an example of the second locking portion.

[0048] Similarly, the indentation piece 28 is formed at a position corresponding to the intermediate portion 36 of the assembled base portion 30. Specifically, the fold 28d is formed at a position where the distance between it and the edge 24a is shorter than the predetermined distance d mentioned above (d1). That is, when the base portion 30 is assembled, the fold 28d is formed to be located behind the front fold 35 (rear opening 3). Also, the edge 28a is formed at a position e3 away from the boundary 26a in the width direction. Distance e3 is approximately the same length as the aforementioned distance e1. That is, when the base portion 30 is assembled, the edge 28a is formed to be at the same position as the folded intermediate portion 36. It is preferable that distance e3 is the distance e1 plus the thickness of the sheet material B. The indentation piece 28 is an example of the first locking portion.

[0049] 2-2 Explanation of Sheet Material B As shown in Figure 3, sheet material B has a long shape in the width direction. In sheet material B, the top surface 11 and the left side surface 13B are arranged side by side in the width direction. The top surface 11 and the left side surface 13B are connected at the boundary 26b between them. A fold is formed at the boundary 26b. The left side surface 13B is an example of the first side surface.

[0050] The upper portion 11 is formed such that its length in the front-to-back direction is the same as the length of the bottom portion 12 in the front-to-back direction. Furthermore, the upper portion 11 is formed such that its length in the width direction is the same as the width direction of the bottom portion 12.

[0051] The left side portion 13B is formed so that its length in the front-to-back direction is the same as the length of the top portion 11 in the front-to-back direction. Also, the left side portion 13B is formed so that its length in the width direction is the same as the width direction of the right side portion 13A. An adhesive tab 14B is connected to the side of the top portion 11 opposite to the left side portion 13B. A fold is formed at the boundary 25b between the top portion 11 and the adhesive tab 14B.

[0052] An outer lid flap 15B is connected to the front side of the left side portion 13B (see Figure 3). A fold is formed on the edge 23b between the left side portion 13B and the outer lid flap 15B. A left rear outer flap 17B is connected to the rear side of the left side portion 13B (see Figure 3). A fold is formed on the edge 24b between the left side portion 13B and the left rear outer flap 17B. The left rear outer flap 17B is an example of a first rear outer flap. The outer lid flap 15B is formed so that its length in the front-rear direction is the same as the length in the width direction of the top portion 11.

[0053] An inner lid flap 16B is connected to the front side of the upper surface portion 11. A fold is formed in the edge 21b between the upper surface portion 11 and the inner lid flap 16B. The inner lid flap 16B is formed so that its length in the front-to-back direction is the same as the length of the outer lid flap 15B in the front-to-back direction.

[0054] An upper inner flap 19B is connected to the rear side of the upper surface portion 11. A fold is formed in the edge 22b between the upper surface portion 11 and the upper inner flap 19B. The upper inner flap 19B is formed so that its length in the front-rear direction is the same as the length in the front-rear direction of the left rear outer flap 17B.

[0055] The length of the upper inner flap 19B in the front-rear direction is shorter than the length of the inner flap 16A in the front-rear direction. Also, the length of the outer flap 15A in the front-rear direction is shorter than the length of the outer flap 15B in the front-rear direction. The length of the upper inner flap 19B in the front-rear direction is shorter than the length of the lower inner flap 19A and the base side portion 31 in the front-rear direction. The length of the left rear outer flap 17B in the front-rear direction is shorter than the length of the right rear outer flap 17A in the front-rear direction (see Figures 2 and 3).

[0056] Adhesive tabs 14d are connected to the front and back sides of adhesive tab 14B, respectively. A fold is formed between adhesive tab 14B and the front adhesive tab 14d. Also, a fold is formed between adhesive tab 14B and the back adhesive tab 14d.

[0057] A folded piece 41 is formed on the side of the edge 61 of the left rear outer flap 17B. Edge 61 is the side of the left rear outer flap 17B opposite to the boundary 26b. In other words, the folded piece 41 is formed on the part of the left rear outer flap 17B that is adjacent to the bottom surface 12 when the packaging box 1 is assembled.

[0058] The folded piece 41 is the portion enclosed by a pair of notches 42U, 42L and a fold 43 formed at a position connecting the ends of the notches 42U, 42L on the left side surface portion 13B. The notches 42U, 42L are notches that extend from an edge 45 that extends parallel to the edge 24a of the left rear outer flap 17B, in a direction that intersects with the edge 24a toward the left side surface portion 13B.

[0059] A locking slit 44 is formed near the center of the folded piece 41 in the width direction, extending from the edge between the cuts 42U and 42L toward the left side portion 13B. The locking slit 44 is a slit that is slightly cut out toward the left side portion 13B, with a width approximately the same as the thickness of the sheet material A.

[0060] The folding piece 41 is formed at a position corresponding to the slit 34 of the lower inner flap 19A that is folded to assemble the pedestal portion 30 when the packaging box 1 is assembled. Specifically, it is formed such that the distance f2 between the fold line 43 and the edge 24b is substantially the same length as the aforementioned distance f1. Also, the distance L between the cut 42L and the end side 61 of the folding piece 41 21 is substantially the same length as the aforementioned distance L 11 and is formed to be so. Also, the distance L in the width direction between the locking slit 44 and the cut 42L 22 is substantially the same length as the aforementioned distance L 12 and is formed to be so. Also, the distance L between the front end portion 44a of the locking slit 44 and the fold line 43 23 is substantially the same length as the aforementioned distance L 13 and is formed to be so.

[0061] 3 Explanation of the assembly method 3-1 Assembly of the main body portion Hereinafter, mainly referring to FIGS. 2 to 8, the assembly method of the packaging box 1 will be described. First, the sheet material A and the sheet material B are joined to form the main body portion 5. Specifically, the front-back directions of the sheet material A and the sheet material B are aligned, and the adhesive margin 14A of the sheet material A is connected to the back surface of a portion near the end 60 of the left side surface portion 13B of the sheet material B. When connecting, the adhesive margin 14A may be connected to the back surface of the portion of the left side surface portion 13B of the sheet material B with the adhesive margin 14A folded to the back side at the fold line with the bottom surface portion 12. Also, the adhesive margin 14c is connected to the back surface of the lid outer flap 15B and the back surface of the left rear outer flap 17B, respectively.

[0062] Also, the adhesive margin 14B of the sheet material B is connected to the back surface of a portion near the end 50 of the right side surface portion 13A of the sheet material A. When connecting, the adhesive margin 14B may be connected to the back surface of the portion of the left side surface portion 13B of the sheet material B with the adhesive margin 14B folded to the back side at the fold line. Also, the adhesive margin 14d is connected to the back surface of the lid outer flap 15A and the back surface of the right rear outer flap 17A, respectively.

[0063] Alternatively, the adhesive tab 14B of sheet material B may be connected to sheet material A, and then the adhesive tab 14A of sheet material A may be connected to sheet material B. The connection between sheet material A and sheet material B may be made using adhesive or staples. The connection between sheet material A and sheet material B may also be made using other methods widely used for joining corrugated cardboard.

[0064] After connecting sheet material A and sheet material B as described above, the top portion 11, left side portion 13B, bottom portion 12, and right side portion 13A are folded along the folds in between them to form a cylindrical main body portion 5.

[0065] The front opening of the cylindrical main body 5 is the front opening 2. Specifically, the area enclosed by the edges 21a, 23a, 21b, and 23b, which are the front edges of the top surface 11, left side surface 13B, bottom surface 12, and right side surface 13A, is the front opening 2. The rear opening of the main body 5 is the rear opening 3. Specifically, the area enclosed by the edges 22a, 24a, 22b, and 24b, which are the rear edges of the top surface 11, left side surface 13B, bottom surface 12, and right side surface 13A, is the rear opening 3.

[0066] Next, the rear opening 3 is closed with the rear flap 6. First, the upper inner flap 19B is folded inward towards the main body 5 at the fold of the edge 22b so that it is perpendicular to the top surface 11. Then, the lower inner flap 19A is folded inward towards the main body 5 at the fold of the edge 22a so that it is perpendicular to the bottom surface 12.

[0067] Next, fold the left rear outer flap 17B inward towards the main body 5 at the fold line of edge 24b so that it is perpendicular to the left side portion 13B. Also, fold the right rear outer flap 17A inward towards the main body 5 at the fold line of edge 24a. Since the right rear outer flap 17A has the same width as the width direction (left-right direction) of the top portion 11 and the bottom portion 12, folding the right rear outer flap 17A as described above will completely close the rear opening 3. Once the rear opening 3 is closed, secure the right rear outer flap 17A, which has closed the rear opening 3, to the main body 5 using tape or the like.

[0068] The right rear outer flap 17A may have a different configuration than described above, as long as it can close the rear opening 3 together with the other flaps. For example, if the rear opening 3 can be closed by the left rear outer flap 17B and the right rear outer flap 17A, the length of the right rear outer flap 17A in the front-rear direction may be shorter than the length of the upper surface portion 11 and the bottom surface portion 12 in the width direction (left-right direction). Alternatively, when the rear opening 3 is closed, the left rear outer flap 17B and the right rear outer flap 17A may be configured such that there is a gap between them.

[0069] 3-2 Assembly of the base After closing the rear opening 3, assemble the base portion 30. First, fold the lower inner flap 19A at the middle fold 33 so that the support portion 32 is raised towards the front opening 2. Specifically, fold the lower inner flap 19A at the middle fold 33 so that the support portion 32 is positioned perpendicular to the base portion 31. That is, fold the lower inner flap 19A at the middle fold 33 so that the angle between the middle portion 36 of the support portion 32 and the base portion 31 is 90°. (See Figure 4.) Here, the angle between the support portion 32 (middle portion 36) and the base portion 31 may be greater than or less than 90°, as long as it does not interfere with supporting the fresh flowers F. In other words, the lower inner flap 19A may be bent at an angle that does not interfere with the support of the fresh flowers F, so as to position the support portion 32 relative to the base portion 31.

[0070] Next, the folded piece 41 is raised from the left rear outer flap 17B. Specifically, the folded piece 41 is separated from the rest of the left rear outer flap 17B at the cuts 42U and 42L, and then folded at the fold line 43 so that the leading end of the folded piece 41 faces the front opening 2 (see Figure 5).

[0071] Next, the raised bent piece 41 is inserted into the slit 34 of the folded lower inner flap 19A (see Figure 5). When inserting the bent piece 41 into the slit 34, ensure that the end 34b of the slit 34 is inserted between the locking slits 44. Insert the bent piece 41 into the slit 34 until the end 34b abuts against the end 44a of the locking slits 44. In this way, the support portion 32 is fixed to the bent piece 41 in a state where it is bent at an angle perpendicular to the base portion 31. Because the end 34b of the slit 34 is inserted and fixed between the locking slits 44, the support portion 32 (intermediate portion 36) becomes less likely to move in the vertical direction. That is, the intermediate portion 36 becomes less likely to fall over.

[0072] Next, the front portion 37 is folded at the front fold line 35 so that its front end faces the upper portion 11. When folding at the front fold line 35, the front portion 37 is folded so that it is perpendicular to the middle portion 36 (see Figure 6). In this way, the front portion 37 is approximately parallel to the rear flap 6 that closes the rear opening 3.

[0073] Next, the push-in pieces 27 and 28 are pushed inward to fix the folded lower inner flap 19A. When the push-in piece 27 is pushed inward, it bends inward at the fold line 27d. When the push-in piece 27 bends inward, its edge 27c comes into contact with the inward-facing surface of the base side portion 31 (see Figure 7). The contact of edge 27c with the surface of the base side portion 31 prevents the base side portion 31 from moving inward. In other words, the push-in piece 27 restricts the base side portion 31 from moving toward the front opening 2.

[0074] When the indentation piece 28 is pushed inward, it bends inward at the fold line 28d. When the indentation piece 28 bends inward, its edge 28a comes into contact with the surface of the intermediate portion 36 facing the upper surface portion 11 (see Figure 8). The contact of edge 28a with the surface of the intermediate portion 36 prevents the intermediate portion 36 from moving toward the upper surface portion 11. In other words, the indentation piece 28 prevents the intermediate portion 36, which has been bent relative to the base portion 31, from falling toward the upper surface portion 11.

[0075] 3-3 Packaging of fresh flowers Once the base assembly is complete, the fresh flowers F are packaged. First, the fresh flowers F are placed inside the main body 5 so that the flower side of the fresh flowers F faces the top surface 11 (see Figure 9). At this time, the portion of the opening g of the soft resin bag G that covers the stem side of the fresh flowers F, facing the rear flap 6, may be fixed with a notch 39. That is, a part of the opening g of the resin bag G may be tucked into the gap created by breaking the notch 39.

[0076] Next, the fresh flowers F are secured to the base 30 using a string-like fixing member H, such as a rubber band. For example, the fixing member H is hooked onto the base side (the side of the tip 37) of each protruding part 38 to secure the fresh flowers F to the base 30.

[0077] After securing the fresh flowers F to the base 30, close the front opening 2 with the lid flap 4. First, fold the inner lid flaps 16A and 16B inward, then fold the outer lid flap 15A inward, and then fold the outer lid flap 15B. Since the outer lid flap 15B has the same width as the length in the front-to-back direction of the top surface 11 and the width direction (left-to-right direction) of the bottom surface 12, when the outer lid flap 15B is folded, the front opening 2 is completely closed. After closing the front opening 2, secure the outer lid flap 15B that has closed the front opening 2 to the main body 5 using tape or the like.

[0078] The inner flap 16B is formed such that its length in the front-to-back direction in Figure 3 is the same as that of the outer flap 15B in the front-to-back direction (see Figure 3). That is, when the front opening 2 is closed, the vertical length of the inner flap 16B is longer than the vertical length of the inner flap 16A. Therefore, when the inner flap 16A is folded inward with the fresh flowers F placed on the base 30, the inner flap 16A covers a wide area of ​​the flower side of the fresh flowers F. As a result, the flower side of the fresh flowers F is covered and securely protected by the inner flap 16B and the outer flap 15B.

[0079] The outer lid flap 15B may differ from the above, as long as it can close the front opening 2 together with the other flaps. For example, if the outer lid flaps 15A and 15B can be folded to close the front opening 2, the width of the outer lid flap 15B may be shorter than the width (left-right) length of the top surface 11 and the bottom surface 12. Alternatively, when the top surface 11 is closed, the outer lid flaps 15A and 15B may be configured such that there is a gap between them.

[0080] With the flower packaging box 1 configured as described above, the base portion 30 can be assembled by inserting the folded piece 41, which is raised from the left rear outer flap 17B, into the slit 34 of the lower inner flap 19A, which is folded at a predetermined point. The folded piece 41 can also be used to fix the bent lower inner flap 19A in place. In other words, the base portion 30 can be assembled easily using a simple procedure. As a result, the time required to assemble the flower packaging box 1 is reduced, and the burden of packaging the flowers F can be lessened.

[0081] Furthermore, the folded lower inner flap 19A is fixed in place by the bent piece 41 inserted into the slit 34. This prevents the folded lower inner flap 19A from moving unnecessarily. In other words, the intermediate part 36 of the support part 32 is prevented from moving unnecessarily in the vertical direction, and the stem side of the fresh flower F is supported in a stable state at a predetermined distance d from the rear opening 3.

[0082] Furthermore, a locking slit 44 is formed in the bent piece 41. This locking slit 44 is formed so that the end 34b of the slit 34 of the bent lower inner flap 19A is inserted into it. As a result, the bent lower inner flap 19A is firmly fixed in place by the bent piece 41, preventing it from moving unnecessarily. Also, the distance L between the front end 44a of the locking slit 44 and the fold 43. 23 The distance L between the end 34b of the slit 34 and the middle fold 33. 13 However, they are configured to be approximately the same distance apart. As a result, the bent piece 41 can be firmly inserted into the slit 34, and the bent lower inner flap 19A is securely fixed by the bent piece 41. In other words, it is prevented the bent lower inner flap 19A from moving unnecessarily.

[0083] Furthermore, the front portion 37 of the support portion 32 is bent at the front fold 35 so as to be perpendicular to the middle portion 36. At this time, the front portion 37 is positioned approximately parallel to the rear flap 6 that closes the rear opening 3. As a result, the surface of the front portion 37 on the side of the front opening 2 comes into contact with the stem portion of the fresh flower F. In other words, the base portion 30 can support the fresh flower F with the surface of the front portion 37. To put it another way, since the portion of the fresh flower F is in contact with and fixed to the surface of the front portion 37 on the side of the front opening 2, the fresh flower F is stably supported by the base portion 30.

[0084] Furthermore, a push-in piece 27 and a push-in piece 28 are formed on the right side surface 13A. These push-in pieces 27 and 28 prevent the base portion 30 from moving unnecessarily. For example, the push-in piece 27, which is pushed inward, prevents the base portion 31, which is blocking the rear opening 3, from moving inward toward the main body portion 5. As a result, the base portion 30 is prevented from moving unnecessarily. For example, the front portion 37, which is the part of the support portion 32 that directly supports the fresh flowers F, is prevented from moving unnecessarily, and the fresh flowers F can be supported in a stable state.

[0085] Furthermore, the inwardly pushed-in piece 28 prevents the intermediate section 36 from tipping towards the upper section 11. In other words, it prevents the base section 30 from moving unnecessarily. For example, the front section 37, which is the part of the support section 32 that directly supports the fresh flowers F, is prevented from moving unnecessarily, allowing the fresh flowers F to be supported in a stable state. Also, since the left side of the intermediate section 36 is fixed by the locking slit 44 of the bent piece 41, both the left and right sides of the intermediate section 36 are firmly fixed. In other words, the fresh flowers F can be supported in a stable state by the base section 30.

[0086] Furthermore, the folded piece 41 is formed by notches 42U and 42L formed in the left rear outer flap 17B. In other words, the folded piece 41 can be formed by the simple operation of making notches 42U and 42L in the left rear outer flap 17B. Also, when assembling the base portion 30, it is only necessary to break the notches 42U and 42L, separate the folded piece 41 from the left rear outer flap 17B, and fold it along the crease 43, thus simplifying the assembly of the base portion 30.

[0087] Furthermore, a notch 39 is formed in the front portion 37. By inserting a part of the opening g of the soft resin bag G, which covers the side of the stem of the fresh flower F, into this notch 39, the soft resin bag G can be secured. This prevents liquids such as water sealed inside the resin bag G, along with the stem of the fresh flower F, from leaking out through the opening g during the packaging process or transportation of the fresh flower F.

[0088] Furthermore, protrusions 38 are formed on both sides of the front portion 37, projecting outwards to the left and right. By attaching a fixing member H, such as a rubber band, to the base portion 30, the fresh flowers F can be secured to the base portion 30. In other words, the fresh flowers F can be easily secured.

[0089] Furthermore, adhesive tabs 14c are provided on the front and rear sides of adhesive tab 14A. Also, adhesive tabs 14d are provided on the front and rear sides of adhesive tab 14B. Adhesive tabs 14c are connected to the back side of the outer lid flap 15B and the back side of the left rear outer flap 17B, respectively. Adhesive tabs 14d are connected to the back side of the outer lid flap 15A and the back side of the right rear outer flap 17A, respectively. Because the flower packaging box 1 has a rectangular parallelepiped shape that is long in the vertical direction, it is prone to twisting and deformation. On the other hand, by connecting the adhesive tabs 14c and 14d to the outer lid flaps 15A and 15B, and the right rear outer flap 17A and left rear outer flap 17B as described above, deformation of the flower packaging box 1 due to twisting can be prevented.

[0090] This disclosure is not limited to the embodiments described above, but is consistent with the intent of the disclosures described above. For example, the flower packaging box 1 may be made of a sheet material other than corrugated cardboard suitable for packaging the flowers F. That is, sheet materials A and B may be made from other sheet materials suitable for packaging the flowers F, such as cardboard.

[0091] Furthermore, the folding piece 41 may have a different configuration from the above embodiment, as long as it can be inserted into the slit 34 and secure the folded lower inner flap 19A. For example, the folding piece 41 may be a corrugated cardboard piece formed in a substantially rectangular shape that is large enough to be inserted into the slit 34, and connected to a position corresponding to the fold line 43 in a state that allows it to be folded relative to the left rear outer flap 17B. Also, for example, in the above embodiment, any of the illustrated components or components described with reference numerals may be omitted. [Explanation of Symbols]
