Further, each of the first engaging pieces 25 is provided with an disengagement hole 28 at a position adjacent to the free end of the second engaging piece 26. To be precise, each disengagement hole 28 is opened so as to expose the end surface of the upper right corner portion of the second engagement piece 26. Each disengagement hole 28 is formed in a shape forming a part of a circle.

The first engaging folding line 33 and the open folding line 31 are reverse ruled lines in which the corrugated cardboard sheet is crushed from the front liner 9B side in the thickness direction, and the second engaging folding line 34 is the corrugated cardboard sheet crushed in the thickness direction from the back liner 9C side. It is a general-purpose ruled line. Further, the folding curve 30 and the discard ruled line 32 are lead ruled lines in which a plurality of cuts (perforations) are formed on the general-purpose ruled line. The perforations of the fold curve 30 located above the open fold line 31 have shorter cuts than the perforations of the fold curve 30 located below the open fold line 31, and the distance (pitch) between the cuts is also large. It is set short. The general-purpose ruled lines and lead ruled lines described above mainly have a function of bending (normally folding) the corrugated cardboard sheet so that the back liner 9C faces inward. The reverse ruled line mainly has a function of bending (reverse folding) the corrugated cardboard sheet so that the front liner 9B faces inward. Further, the lead ruled line also has a function of cutting the corrugated cardboard sheet. The above-mentioned folding curve 30 and the like are not limited to general-purpose ruled lines, reverse ruled lines, and lead ruled lines, and can be any structure such as perforations that has a function of bending or cutting a corrugated cardboard sheet in a desired direction. good.

As shown in FIG. 4, the blank 3A punched from one corrugated cardboard sheet is folded in half. Specifically, the pair of first side walls 22 (pair of guide pieces 24) are each folded back (normally folded) along the discard ruled line 32, and the second side wall 23 located on the other side in the flow direction is an adhesive (a pair of guide pieces 24). Alternatively, it is overlapped and fixed on the joint piece 27 via a double-sided tape). As a result, the packaging tool 3 (blank 3A) is in a folded state. In this state, each of the first side walls 22 (each guide piece 24) is folded back in about half to form a double layer, and the pair of second side walls 23 overlap each other so as to coincide with each other. Further, the first side wall 22 and the second side wall 23 are not bent at the folding curve 30 and are widened. The folded packaging tool 3 is transported or stored in a state in which a plurality of folded packaging tools 3 are laminated and bundled.

[Assembly of packaging container]
An example of the procedure for assembling the packaging container 1, in other words, an example of the procedure for packaging cut flowers will be described with reference to FIGS. 1 and 5. FIG. 5 is an enlarged cross-sectional view showing a portion in which the packaging tool 3 is connected to the bucket 2. It is assumed that the lower part of the stem of the plurality of cut flowers is inserted into the accommodating portion 10 of the bucket 2. Further, it is assumed that the plurality of cut flowers are not bundled with a rubber band at the lower part of the stem or wrapped with newspaper, film, or the like, but are merely inserted into the accommodating portion 10.

<Formation of packaging>
The operator opens the folded wrapping tool 3 (see FIG. 4) to form a square tubular body 20. Specifically, the operator opens the first side wall 22 which is folded back by the discard ruled line 32 and doubled so as to form one sheet, and opens the first side wall 22 and the second side wall 23 with a folding curve 30. Fold it forward and make it substantially orthogonal (see FIG. 1). The pair of the first side wall 22 and the pair of the second side wall 23 are alternately connected in the circumferential direction to form a cylindrical body 20 having a square tubular shape in which the opening gradually expands from the lower side to the upper side.

In this state, the pair of first side walls 22 face each other in the front-rear direction with the internal space S2 of the cylinder 20 interposed therebetween, and the pair of second side walls 23 face each other in the left-right direction with the internal space S2 of the cylinder 20 interposed therebetween. Since the first side wall 22 is wider in the lateral direction than the second side wall 23, the tubular body 20 is formed in a rectangular tubular shape that is long in the left-right direction when viewed from a plane. The pair of first engaging pieces 25 extend downward from the lower end of the tubular body 20 at positions facing each other in the left-right direction with the internal space S2 interposed therebetween. The pair of guide pieces 24 extend downward from the lower end of the tubular body 20 at positions facing each other in the front-rear direction with the internal space S2 interposed therebetween (positions displaced in the circumferential direction from the pair of first engaging pieces 25). There is.

<Connecting packaging>
Next, the operator connects (attaches) the packaging tool 3 to the bucket 2. Specifically, the worker arranges the wrapping tool 3 above the cut flowers housed in the accommodating portion 10, lowers the wrapping tool 3, and relatively arranges the cut flowers from the lower surface opening of the tubular body 20 to the internal space S2. To enter. As the wrapping tool 3 descends, the pair of guide pieces 24 enter along the inner surface of the accommodating portion 10 in the front-rear direction, and the pair of first engaging pieces 25 slightly outward along the first engaging folding line 33. It descends along the outer side of the outer frame portion 11 in the left-right direction while folding in (see FIG. 1). The operator allows the pair of first engaging pieces 25 to enter the pair of engaging holes 13 of the outer frame portion 11 from above while bending inward so as to approach each other (see FIG. 1).

When the lower end of the tubular body 20 comes into contact with the upper end surface portion 12 of the bucket 2 (see FIG. 1), the lowering of the packaging tool 3 is restricted, and the upper portions of the plurality of cut flowers are surrounded by the tubular body 20. The tubular body 20 is set to a height equal to or higher than the height of a cut flower extending upward from the upper end surface portion 12 of the bucket 2, so that the upper portion of the cut flower does not protrude from the upper surface opening of the tubular body 20. Further, as shown in FIGS. 1 and 5, the pair of first engaging pieces 25 are pressed (engaged) from the inside against the lower edge portion 13D of the pair of engaging holes 13 by their own elastic force.

After engaging each first engaging piece 25 with the lower edge portion 13D of the engaging hole 13, the operator pushes the pair of second engaging pieces 26 into the pair of engaging holes 13. Each of the second engaging pieces 26 bends inward along the second engaging folding line 34 while being hollowed out from the first engaging piece 25, and bends over the upper edge portion 13U of the engaging hole 13 to get over the engaging hole. Enter 13 As shown in FIGS. 1 and 5, the pair of second engaging pieces 26 are pressed (engaged) from the inside against the upper edge portion 13U of the pair of engaging holes 13 by their own elastic force.

As described above, the connection of the packaging tool 3 to the bucket 2 is completed (see FIG. 1). That is, the packaging container 1 is completed. The packaging container 1 containing cut flowers is delivered to users such as retail stores and individuals. Since the upper portions of the plurality of cut flowers housed in the bucket 2 are arranged in the internal space S2 of the tubular body 20, they are protected from an impact or the like applied from the outside during transportation or the like.

According to the packaging tool 3 according to the present embodiment described above, the lower part of the tubular body 20 is arranged in the upper part of the bucket 2, each first engaging piece 25 is inserted into the engaging hole 13, and then each second engagement piece 25 is inserted. By pushing the unit 26 into the engaging hole 13, the packaging tool 3 can be connected to the bucket 2. The pair of first engaging pieces 25 and the pair of second engaging pieces 26 engage with the lower edge portion 13D and the upper edge portion 13U of the pair of engaging holes 13 at positions where the bucket 2 is sandwiched from both the left and right sides ( (See FIG. 5), it is possible to restrict the movement of the packaging tool 3 up and down, left and right, and back and forth with respect to the bucket 2. In this way, the packaging tool 3 can be easily connected to the bucket 2 and the connected state can be maintained. As a result, for example, even if the user grabs the packaging tool 3 and lifts the entire packaging container 1, it is possible to prevent the packaging tool 3 from coming off the bucket 2.

Further, according to the packaging tool 3 according to the present embodiment, the pair of guide pieces 24 is made to enter the inside of the bucket 2, and the pair of first engaging pieces 25 are made to be along the outside of the bucket 2, so that the pair of guide pieces 24 is attached to the bucket 2. The installation position of the cylinder 20 can be accurately adjusted.

Further, according to the packaging tool 3 according to the present embodiment, since the shape is such that the upper part of the cylinder 20 expands, a plurality of cut flowers (petals or the like) whose upper portion expands in the radial direction are strongly pressed against the inner surface of the cylinder 20. Is suppressed. That is, it can be wrapped in the cylinder 20 while suppressing damage to the cut flowers. As a result, even if it is omitted to bundle a plurality of cut flowers with a rubber band or wrap the bundled cut flowers with a film, paper, or the like, the plurality of cut flowers can be appropriately protected. As a result, it becomes possible to efficiently and quickly perform the packing work of cut flowers using the bucket 2 and the wrapping tool 3.

Further, according to the packaging tool 3 according to the present embodiment, even if the tubular body 20 has a square tubular shape extending upward from the lower part, each first side wall 22 is discarded and folded back along the ruled line 32 to make it flat. Can be folded into (see FIG. 4). As a result, the packaging tool 3 can be made compact, so that the transportation cost can be reduced and the storage space can be saved. Further, at the time of use, the square tubular body 20 can be easily formed by making the first side wall 22 and the second side wall 23 orthogonal to each other while opening the folded first side wall 22.

[Opening the packaging container]
Next, opening of the packaging container 1 will be described with reference to FIG. FIG. 6 is a perspective view illustrating a second opening method of the packaging container 1.

<First opening method>
As a first opening method, the user can disconnect the packaging tool 3 from the bucket 2 and remove the packaging tool 3. Specifically, the user hangs a finger inserted into the disengagement hole 28 opened in the first engagement piece 25 on the second engagement piece 26, and pulls out the second engagement piece 26 to the outside. Each of the second engaging pieces 26 is pulled out from the engaging hole 13 while bending over the upper edge portion 13U of the engaging hole 13. As a result, the connection of the packaging tool 3 to the bucket 2 is released.

Subsequently, the user lifts the tubular body 20, pulls out each guide piece 24 from the accommodating portion 10, and pulls out each first engaging piece 25 from the engaging hole 13. As a result, the wrapping tool 3 is separated from the bucket 2, and the upper portions of the plurality of cut flowers supported by the bucket 2 are exposed. After all the cut flowers are taken out, the bucket 2 is collected for reuse, and the packaging tool 3 is discarded (or may be reused).

As described above, the user can insert a finger into the disengagement hole 28 and pull out the second engagement piece 26 engaged with the upper edge portion 13U of the engagement hole 13. As a result, the connection state of the packaging tool 3 with respect to the bucket 2 can be easily released.

<Second opening method>
Further, as a second opening method, the user can expose the upper portions of a plurality of cut flowers without disconnecting the packaging tool 3 from the bucket 2. As shown in FIG. 6, for example, the user grasps the upper end portion of any one of the first side wall 22 and pulls the first side wall 22 outward and downward, and pulls the first side wall 22 on both the left and right sides of the folding curve 30 (square cylindrical corner). It is separated from the pair of second side walls 23 along the boundary line forming the above. Each fold curve 30 has a finer perforation pitch (shorter seam) above the open fold line 31, so that it is easier to cut. The first side wall 22 is bent outward along an open fold line 31 while being cut along a pair of fold curves 30 (boundary lines forming corners of a square cylinder). As a result, substantially the upper half of the first side wall 22 is opened, and the upper portions of the plurality of cut flowers housed in the internal space S2 are exposed. Even when the package is opened by the second opening method, after all the plurality of cut flowers are taken out, the packaging tool 3 is separated from the bucket 2 by the same procedure as the first opening method, and the bucket 2 is collected. And the packaging tool 3 is discarded.

As described above, by opening the substantially upper half of the first side wall 22 to the outside, the upper part of the internal space S2 of the tubular body 20 can be greatly opened. As a result, a plurality of cut flowers housed in the internal space S2 can be easily taken out without removing the wrapping tool 3 from the bucket 2.

In the above-mentioned example of the second opening method, substantially the upper half of one first side wall 22 is open, but the present invention is not limited to this. One of the second side walls 23 may be bent outward along the open folding line 31 while being cut along the pair of folding curves 30, and substantially the upper half of the second side wall 23 may be opened (not shown). In addition, a pair of first side walls 22 (or a pair of second side walls 23) are cut along each folding curve 30, and all side walls 22 and 23 are bent outward along an open folding line 31. May (not shown).

Further, in the packaging tools 3 and 4 according to the present embodiment (including a modified example, the same applies hereinafter), the tubular body 20 is formed in a square cylindrical shape (square columnar shape) in which the opening widens from the lower side to the upper side. , The present invention is not limited to this. The tubular body 20 may be formed in a substantially cylindrical shape that expands in diameter upward, or is formed in a polygonal tubular shape other than a square cylindrical shape, such as a triangular cylindrical shape (triangular columnar shape) that expands upward. It may be (not shown). Even in these cases, it is preferable to provide a discard ruled line 32 for folding the tubular body 20 flat. Further, if the tubular body 20 is not folded, the discard ruled line 32 may be omitted (not shown). Further, the tubular body 20 may have a tubular shape (cylindrical shape, square tubular shape) having substantially the same cross section from the lower side to the upper side (not shown). Further, similarly to the packaging tools 3 and 4 (cylindrical body 20), the bucket 2 may be formed in a polygonal tubular shape other than a cylindrical shape or a square cylindrical shape (not shown).

Further, in the packaging tools 3 and 4 according to the present embodiment, the disengagement hole 28 is formed in the vicinity of the upper corner portion of the second engagement piece 26, but the present invention is not limited to this.
