DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box in which a hanger for hanging display is connected to a main body for accommodating an object to be packaged, and a method for stacking and packaging the packaging box.

[0002]

2. Description of the Related Art At present, various types of photographic films are used, and 135 types of photographic film cartridges are widely used for general photographing. In this photographic film patrone, a spool is rotatably provided inside a cylindrical patrone main body, and the end of a 35 mm wide strip-shaped photographic film is fixedly wound around the spool.

Recently, a spool around which a photo film is wound is housed in a cartridge body assembled from a resin molded product. When not in use, all of the photo film is wound into the cartridge body, and the spool is used at the time of use. Photographic film cartridges in which a photographic film is fed by rotating the photographic film are sold. The photo film cartridges are individually housed in containers having a moisture-proof property called P cases, and one by one.
Or a plurality of them are sold together in a packaging box. As a packaging box, besides simply having a cube shape,
In some cases, a box-shaped storage unit is provided with hanging pieces for hanging at a store for display. These packaging boxes are collected in a transport bin, packed, and shipped to retail stores.

FIG. 5 shows a photographic film cartridge containing a P case. Photo film cartridge 1
0 is a photo film 1 inside the cartridge body 11.
The spool 13 around which the spool 2 is wound is housed rotatably. The cartridge body 11 is provided with a projecting film passage 14 for allowing the photo film 12 to enter and exit, and the film passage 14 incorporates a lid member 15 for preventing light from entering therethrough. I have. The cover member 15 is rotatably assembled between an open position where the film passage 14 is opened to allow the photo film 12 to enter and exit, and a closed position where the film passage 14 is closed.

The photographic film cartridges 10 are individually housed in a moisture-proof P case 17. P case 1
Reference numeral 7 denotes a container body 18 and a lid 19, each of which is made of an integrally molded resin product. The container body 18 is a cylindrical body having a bottom. After the photographic film cartridge 10 is stored in the cylindrical body, a lid 19 is attached to the opening end side.

FIG. 6 shows a packaging box for a photo film cartridge, in which three photo film cartridges 10 housed in a P case 17 are integrally packaged. The packaging box 20 has a vertically long box-shaped main body 21.
And a hanger portion 22 is integrally provided above the upper portion. The main body 21 is configured to have a size that allows three P cases 17 to be stacked and stored in a horizontal posture. The hanger part 22 is formed with a hole 23 through which a hanger is inserted at a store and the packaging box 20 is hung and displayed.

[0007]

As shown in FIG. 7, when packing boxes 20 each having a hanger section 22 are stacked in a transport box 25 for packing, the packing box 20 is placed with the hanger section 22 facing upward. It is common to align 20. However, in this method, a gap is formed in the upper part in the shipping box 25, so that not only the space efficiency is poor, but also the shipping box 25 becomes large. Moreover, the transport box 25 has a low strength against compression and the number of loading stages is limited, so that the transport efficiency is extremely poor.

[0008] Therefore, as shown in FIG.
0 is alternately combined, and each hanger part 22 is arranged so as to be superimposed on the front surface of the other main body part 21 and packed in the transport box 26. According to this method, since no gap is formed in the storage portion of the hanger portion 22, the space efficiency in the transport box 26 can be improved, and the compressive strength of the transport box 26 can be improved.
However, in this method, at least one side of the transport box 26 is twice as long as the length of the main body 21 of the packaging box 20, so that the outer shape is also likely to increase in size.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a packaging box with a hanger which can improve the compressive strength of a transport box and improve transport efficiency, and a method of stacking and packaging the same. Aim.

[0010]

In order to achieve the above object, a packaging box with a hanger of the present invention has a ruled line or perforation formed on a boundary between a main body and a hanger, and the hanger is oriented vertically. It can be bent freely.

Further, in the method of the present invention, a predetermined number of packaging boxes are aligned so that the hanger portions project in the same direction and the hanger portions are parallel to each other. Thereafter, each of the hanger portions protruding on the same surface of the packaged object is vertically bent at the base portion, and is integrally packed in a state of being superimposed on an adjacent packaging box. Also, after a predetermined number of packaging boxes are aligned so that the respective hanger portions are arranged side by side, the aligned body is stacked so that the hanger portions projecting side by side are parallel to produce a packaged body. Thereafter, each of the hanger portions protruding on the same surface of the packaged object may be vertically bent at the base portion, and may be integrally packaged in a state of being superimposed on the adjacent alignment body. Preferably, the hanger portion is bent inward from the outer peripheral side of the packaged object.

[0012]

FIG. 1 is an exploded view of a packaging box for a photo film cartridge according to the present invention. The photo film cartridge 10 containing a P case shown in FIG.
It is to be packaged together individually. The packaging box 30 is configured by integrally providing a hanger section 32 above a vertically elongated box-shaped main body section 31, and is assembled by folding one sheet of paper. The main body 31 includes a rear cover 33, a right side cover 34, a front cover 35, a left side cover 36, a bottom cover 37, and a folding top cover 38. The back cover portion 33 is provided with adhesive margin pieces 39a and 39b.
After gluing the glue margin piece 39a and the left side cover part 36, the glue margin piece 39b and the bottom cover 37 are glued, and the upper lid 38 is folded in, whereby the packaging box 30 is completed.

The hanger part 32 is provided continuously on the upper end side of the back cover part 33, and is bent substantially at the center to the front side to form a double structure of a front part 32a and a back part 32b. . The front portion 32a is formed to be longer than the back portion 32b. When the packaging box 30 is assembled, the lower portion of the front portion 32a is overlapped with the back cover portion 33 and enters the main body portion 31. Has become. The hanger part 32 is formed with a hole 43 through which a hanger is inserted at a store and the packaging box 30 is hung and displayed. The front part 32a and the back part 32b have
A ruled line 40 is formed on the boundary with the back cover part 33. The ruled line 40 is, for example, as shown in FIG.
The paper material 30a of the packaging box 30 is sandwiched between the mold and the female mold 42, and is formed by compression and deformation.

FIGS. 3 and 4 show a packaging box 30 containing three photographic film cartridges 10 each containing a P case.
Are schematically shown in a stacking and packing process in which (m × n) pieces are stacked and packed in a shipping box. In this embodiment, m = 6 and n = 5. The packaging box 30 is transported to the alignment and collection position with the hanger portions 32 projecting in the same direction,
The hanger portions 32 are integrated so as to be arranged side by side (FIG. 3
(A)). In the present embodiment, the packaging boxes 30 are arranged such that the hanger portions 32 protrude rightward in the drawing. Then, when the number m of aligned stacks of the packaging boxes 30 becomes six, the stacks 51 are transferred to the stacking position and stacked (FIG. 3C).

When stacking and stacking are repeated and the number n of stacking stacks at the stacking position becomes three, the direction of protrusion of the hanger portion 32 of the stack 51 manufactured at the alignment stacking position is shown in the figure. The direction is reversed so as to be the left direction (FIG. 3
(B)). Thereafter, the inverted stack 52 is transferred to the stacking position and stacked.

When the number n of stacked stacks becomes five, the stacked stack 53 is a surface on which the hanger portion 32 of the stacked stack 51 in the lower layer protrudes (right side in the figure). It is rolled over with a ridge 53a consisting of a bottom and a bottom as a support axis (FIG. 4D). As a result, the hanger portion 32 of the stack 51 protruding from the stack 53 is bent toward the center of the stack 53 and overlaps the adjacent stack 51 and the inverted stack 52. . At this time, since the ruled line 40 is formed at the base of the hanger part 32, the hanger part 32 is reliably bent along the ruled line 40. Thereby, the hanger part 32 is not broken at a part other than the root part, and the appearance of the packaging box 30 is not spoiled.

The overturned stack 53 is transferred to a packing position and packed in a shipping box 50. At the packing position, a corrugated cardboard sheet 54 serving as a material of the transport box 50 is positioned.
3 is placed (FIG. 4E). Then, when the corrugated stack 53 is wrapped by the corrugated cardboard sheet 54, the stacking and packing of the packaging box 30 is completed (FIG. 4F).

At this time, the hanger part 32 of the reversal stack 52 protruding above the stack 53 is pressed by the corrugated cardboard sheet 54 placed on the upper surface thereof, and is directed toward the center of the stack 53. Is folded and superimposed on the adjacent inverted stack 52 and stack 51. Also in this case, each hanger part 32 is reliably bent along the ruled line 40. Thus, no (6 × 5) packaging boxes 30 are formed in the transport box 50 without any gaps.
Is stored.

In the above embodiment, the example in which the ruled line 40 is formed on both surfaces of the front part 32a and the back part 32b constituting the hanger part 32 has been described.
The hanger 32 can be sufficiently prevented from being bent at a portion other than the root by simply forming the hanger 32 on either the 2a or the back surface 32b.

In the above embodiment, the main body 31
Although the ruled line 40 is formed on the boundary between the hanger 32 and the hanger 32, a perforation may be formed as long as the hanger can be easily bent at the base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the integrated packing method of the present invention, the size and volume of a shipping box and the amount of packing material used when packing a box of a photo film cartridge containing a P case are measured.
A comparison was made with the transport box according to the conventional integrated packing method shown in FIG. The packaging box to be packed has the shape shown in FIG. 1, and a "three pack" product for storing three P-cased photo film cartridges and a "five pack" for storing five photo film cartridges.
Each of the two types of packaging boxes was packed. Table 1 shows the sizes of the two types of packaging boxes, "three packs" and "five packs", and also summarizes the size, volume, and amount of packing materials used for the shipping boxes when each packing box is packed. Table 2
Shown in

[0022]

[Table 1]

[0023]

[Table 2]

As shown in Table 2, the volume of the shipping box according to the integrated packing method of the present invention is smaller in both the "three packs" and the "five packs" than in the conventional method. In the case of "3 pieces", it was about 22.3%, and in the case of "5 pieces", it was about 16.2%. Thus, according to the integrated packing method of the present invention, it was confirmed that the size of the shipping box can be reduced, and for example, the loading space in the transport vehicle can be reduced and the shipping efficiency can be improved. In addition, as the size of the shipping box is reduced, the amount of packing material used is also reduced. In the case of "3 pieces", about 17.0% of the conventional method, and in the case of "5 pieces", about 14% It was found that 0.3% of the packaging material was saved. Thereby, it was confirmed that the integrated packing method of the present invention also contributed to reduction of packing cost.

Next, in order to confirm the compressive strength of the shipping box according to the integrated packing method of the present invention, a compression test was performed to measure the critical load value of the shipping box. For comparison, FIG.
The critical load value was also measured for the transport box according to the conventional method shown in Table 3 and the results are shown in Table 3.

[0026]

[Table 3]

As shown in Table 3, the critical load values of the shipping containers according to the integrated packing method of the present invention are "3 packs" and "5 packs".
It can be seen that in each case, the improvement is almost twice as large as that of the conventional method. This is presumed to be because there was no extra gap in the shipping box. Therefore, according to the integrated packing method of the present invention, since the compressive strength of the shipping box is greatly improved as compared with the conventional method, it is possible to increase the number of loading stages of the shipping box, and it is confirmed that the transport efficiency can be further improved. Was done.

The photographic film cartridge packaging box of the present invention has a ruled line or perforation formed on the boundary between the main body and the hanger, and the hanger is easily bent at the base. However, since the packaging box is displayed hanging at the storefront, the base of the hanger may be damaged when ruled lines or perforations are formed or when the hanger is bent during stacking and packing. Must be avoided.

Then, ten types of packaging box sample products A to J having different formation depths of the ruled lines were prepared,
The relationship between the formability of the ruled line and the bending strength of the ruled line portion was confirmed. The formability of the ruled line was evaluated based on the presence or absence of a ruled line crack immediately after formation. The bending strength of the ruled line portion was evaluated based on whether or not the ruled line portion was damaged when the hanger portion was bent in the stacking and packing process, and whether or not the bending position was appropriate. Sample products A to J have a basis weight of 270 to
400g / m ² paper material, male width W1, female width W2
, And forming depth D (see FIG. 2)
0.5-0.8mm, 1.1-1.4mm, 0.3-
Ruled lines were formed using a 0.7 mm punch.

Table 4 shows the formation depths of the ruled lines and the evaluation results of the sample products A to J. In the table, the evaluation symbol “○” indicates good, the symbol “部分” indicates that the crease is partially broken or broken, or the bending position is inappropriate, and the symbol “×” indicates that it is not practical.

[0031]

[Table 4]

According to the results shown in Table 4, the ruled line formation depth was 0.3
It has been found that setting the thickness within the range of mm to 0.7 mm can surely prevent occurrence of breakage of the ruled line at the time of forming the ruled line and breakage of the root portion due to bending of the hanger portion.

[0033]

As described above, according to the method for stacking packaging boxes with hangers according to the present invention, the packaging boxes are aligned with the hangers protruding in the same direction to produce a packaged body. Each hanger protruding on the same surface is vertically bent at the base and packed together in a state of being stacked on the adjacent packaging box, so there is no extra gap in the shipping box, and the size of the shipping box is small. For example, it is possible to save space for loading in a transport vehicle. In addition, since there is no gap in the shipping box, the compressive strength of the shipping box is improved, and the number of loading stages of the shipping box can be increased. Thus, the transportation efficiency of the packaging box with the hanger can be improved.

Further, according to the packaging box with a hanger of the present invention, a ruled line or perforation is formed on the boundary between the main body and the hanger, and the hanger is easily bent along the ruled line or perforated line. The hanger portion is prevented from being bent at a portion other than the base portion, and does not impair the appearance of the packaging box.
