Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated cardboard box having a partition wall, which can be made from a single sheet of raw material, and more specifically, a flat rectangular parallelepiped small box containing pouches is laminated in multiple stages. The present invention relates to a cardboard box which is convenient to be transported in a crushed state.

[0002]

2. Description of the Related Art Food contained in pouches, such as curry and soup, can be eaten simply by removing the pouch from a flat rectangular parallelepiped subdivision box and heating it with boiling water. It is well established.

Such pouch-containing foods are generally
Many subdivided boxes containing this are put in cardboard boxes and transported.

[0004]

The applicant of the present application has made a cardboard box which can accommodate the pouch-containing subdivided boxes in a stacked state of 10 layers, and the subdivided boxes are accommodated in the corrugated cardboard box to perform a vibration drop test. However, although the cause is not always clear, it was found to include the possibility of pinholes occurring in the pouch.

Further, a cardboard box which can accommodate the pouch-containing subdivided boxes in a stacked state of 5 layers is formed, the pouch-containing subdivided boxes are accommodated in the corrugated cardboard box, and the cardboard boxes are stacked vertically. It was found to include the possibility of bag breakage.

That is, for example, when the pouch-containing subdivided boxes are stored in a corrugated cardboard box in 10 layers, it is assumed that one corrugated cardboard box is 7.2 kg, and the same number of the pouch-containing subdivided boxes is stored in the corrugated cardboard box in five layers. In this case, this cardboard box weighs 7.4 kg, and there is no great difference in weight between the two, but the five-tier cardboard box is flatter than the ten-tier cardboard box. Therefore, assuming that it is possible to stack, for example, 6 cardboard boxes stacked in a stack of 10 on the bed of a truck, if the cardboard boxes of 5 stacks are stacked on the bed of the same truck, 12 boxes can be stacked up and down. Since it is possible to stack and stack, the bottom cardboard box is 7.4 kg × 11 boxes = 8 for a 5-tier cardboard box
A load of 1.4 kg will be applied. On the other hand, 10
In the case of a stacked cardboard box, the load of the cardboard box above it, that is, the load of 7.2 kg x 5 boxes = 36.0 kg is applied to the lowermost cardboard box.

As can be understood from the above description, the smaller the number of pouches containing pouches to be stacked in the vertical direction is, the larger the load applied to the lower corrugated cardboard boxes when the corrugated cardboard boxes are stacked is the upper and lower ones. The box is deformed and a load is directly applied to the pouch, which may cause bag breakage in the pouch.

Therefore, an object of the present invention is to reduce the possibility that pinholes or bag breakage will occur in the pouches even when the pouch-containing subdivided boxes are stacked and accommodated in multiple stages. To provide.

A further object of the present invention is to provide a cardboard box suitable for accommodating and transporting pouch-containing subdivided boxes in a five-tier stack.

Another object of the present invention is to provide a cardboard box suitable for accommodating and transporting a total of 30 pouch-containing small-sized boxes in a 5-level stack.

The corrugated cardboard box 1 having the unfolded structure described with reference to FIG. 1 becomes a rectangular parallelepiped box shown in FIG. 2 when assembled. 3 to 5 show the assembling procedure of the cardboard box 1.
Will be described with reference to.

To assemble the cardboard box 1, first, the glue margin 30 of the sheet material in the developed state shown in FIG. 1 is applied to the fourth side wall portion 5 and the lid flap 10 associated therewith by using a double-sided adhesive tape or glue. It is adhered to the edge of the bottom flap 15 (Fig. 3). Next, the short second and fourth bottom flaps 1
Folding 7, 19 and the second and fourth related to this
The partition flaps 18 and 20 are raised (FIG. 4). Then, fold the elongated first and third bottom flaps, and
The associated first and third partition flaps 17, 19 are raised. The first and third partition flaps 17, 19
In the process of standing up, the first and third partition flaps 1
First vertical slits 23, 23 formed in
Enter the lateral slits 24 of the second and fourth partition flaps 18, 20 and finally reach the lateral slits 24.
The second and fourth partition flaps 18 and 20 are received over the range (FIG. 5). As described above, the first to fourth partition flaps 17 to 20 cross each other and stand upright inside the cardboard box 1, so that a total of six sections 40 to 45 of equal size are formed.

That is, inside the cardboard box 1, the elongated first and third partition flaps 17 and 19 extend along the longitudinal direction at the widthwise central portion of the cardboard box 1, and the first and third partition flaps 17 and 19 are provided. Six partitions 40 to 45 are formed inside the corrugated cardboard box 1 by the partition flaps 17 and 19 being traversed by the short second and fourth partition flaps 18 and 20.

As will be readily understood by those skilled in the art, referring to FIG. 1, the first and third partition flaps 1 will be described.
Fold 2 from the deep end of the first vertical slit 23 of Nos. 7 and 19
The distance d1 to 1 is substantially equal to the length d2 of the second and fourth partition flaps 18, 20 side portions of the second vertical slit 24 (d1 = d2). Further, the distance d3 from the deep ends of the horizontal slits of the first and third partition flaps 17 and 19 to the first vertical slit 23 is such that the second and fourth bottom flap portions 13 of the second vertical slit 24, 15 side length d4
Is substantially equal to (d3 = d4). Further, the distance d5 from the ends of the second slits 24 on the second and fourth bottom flap portions 13, 15 side to the folds 16 is the first and the third from the corners of the first and third bottom flaps 12, 14. 3 divider flaps 17,
It is substantially equal to the distance d6 to the deep end of the lateral slit 22 of 19 (d5 = d6). Further, the length d7 of the first vertical slit 23 of the first and third partition flaps 17, 19 is
Second and fourth partition flaps 1 of the second vertical slit 24
From the end on the 8 and 20 side, the second and fourth partition flaps 1
Substantially equal to the distance d8 to the side edges of 8 and 20 (d7
= D8).

With the above configuration, the elongated first and third partition flaps 1 extending in the longitudinal direction inside the corrugated cardboard box 1 are provided.
The longitudinal edges of 7, 19 have end walls 3, due to the notch c.
5 (the second and fifth short side wall portions 3 and 5) are spaced apart from each other. On the other hand, the short second and fourth partition flaps 1
The edges of 8, 20 are located adjacent to the side walls 2, 4.

Further, these partition flaps 17 to 20 are
It has substantially the same height as the height of the cardboard box 1. More specifically, since the partition flaps 17 to 20 close the lid flaps 7 to 10, they are positioned slightly lower than the height of the cardboard box 1 by the thickness of the lid flaps 7 to 10.

The second and fourth partition flaps 18 and 20 which are parallel to each other and traverse the inside of the corrugated board box 1 are arranged so that when the corrugated board box 1 is assembled, the first and third partition flaps extend longitudinally in the center of the corrugated board box 1. Since it is folded before the partition flaps 17 and 19 of the above, the upper edges of the second and fourth partition flaps 18 and 20 that traverse the corrugated board box 1 are the first and third partitioning portions by the thickness of the corrugated cardboard material. The flaps 17 and 19 are located slightly above the upper edges (see FIG. 5).

Further, since the long partition flaps 17 and 19 have a tapered shape, when the cardboard box 1 is assembled, particularly, the first and third partition flaps 17 and 1 are provided.
It is possible to improve workability when inserting 9 into the second vertical slit 24.

Since the short partition flaps 18 and 20 have a tapered shape, the partition flap 1
It is possible to improve workability when the cardboard boxes 8 and 20 are folded to stand up inside the cardboard box 1.

Each of the six sections 40 to 45 of the cardboard box 1 contains pouches stacked in multiple stages, specifically, five stages (n = 5), as can be understood from FIG. A subdivision box 50 is accommodated. That is, the cardboard box 1 can accommodate a total of 30 pouch-containing subdivided boxes 50. FIG. 7 shows a flat rectangular parallelepiped subdivision box 50 accommodating a flat pouch 51 having a rectangular outer contour.
Indicates. The parcel box 50 is generally made from paper having a suitable thickness. This small box 50 is 130mm wide x
It has a size of 165 mm length × 22 mm width (thickness).

This type of pouch 51 is widely used for storing retort foods that can be eaten only by heating with hot water. Specifically, the pouch 51 contains a liquid or paste form. Foods containing solid ingredients as needed,
For example, curry, stew, sauce, soup, etc. are stored.

The pouch 51 generally includes a peripheral web 51a, but the overall size of the pouch 51 is 125 mm in width × 175 mm in length.
× Thickness is about 17 mm. With the pouch 51 of this size,
As a result of the experiment, the weight of the pouch 51 containing the contents is about 11
It has been found that if the amount is from 0 g to about 230 g, it is possible to prevent pinholes from being generated in the pouch 51.

In order to prevent breakage of the pouch 51 and generation of pinholes, the viscosity of the contents of the pouch 51 is 1000 to 15000 mPa · s when measured with a B-type viscometer at room temperature. Experiments have shown that it is preferable. That is,
It was found that if the viscosity is lower than this range, the pouch 51 may be broken, and if the viscosity is higher than this range, a pinhole may be generated on the pouch 51. . Incidentally, the pouch 51 is made of a composite material such as a plastic film, an aluminum foil, and a vapor deposition film.

Pouch 51 and small box 5 for containing it
Regarding the relationship with 0, as can be understood from the above-mentioned example, the width dimension of the pouch 51 is slightly smaller than the subdivision box 50 (width: pouch <subdivision box), and the vertical dimension of the pouch 51 is the subdivision box 50.
Slightly larger (vertical: pouch> subdivided box), pouch 5
The thickness of 1 is slightly thinner than the subdivision box 50 (thickness: pouch <subdivision box). As a result, the pouch 51 is prevented from floating in the sub-packing box 50, a pinhole is prevented from being generated in the pouch 51, and a compressive load is applied to the pouch 51 in the sub-packing box 50. It is possible to reduce the possibility that the pouch 51 will be broken.

In order to prevent the pouch 51 from floating in the sub-compartment box 50, the pouch 51 is not limited to the above-mentioned specific examples.
The following conditions may be satisfied as 1 or 2 or all. (1) Vertical dimension: approx. 3 mm ≤ (pouch 51-small box 5
0) ≤ about 15 mm; (2) Width dimension: 0 ≤ (small box 50-
Pouch 51) ≤ about 10 mm; (3) Thickness: 0 ≤ (parcel box 50-pouch 51) ≤ about 10 mm;

Particularly, the vertical dimension of the pouch 51 is set in the small box 50.
If the pouch 51 is slightly larger than the pouch 51, when the sub-package 50 is opened, at the same time, a part of the peripheral web 51a of the pouch 51 projects to the outside.
There is a secondary advantage that it is easier to take out.

After placing the pouch-containing subdivided boxes 50 in each of the six compartments 40 to 45 of the corrugated cardboard box 5 in a stacked manner of five stages, first, the end walls 3 and 5 (second side wall portion 3,
The short lid flaps 8, 10 extending upward from the fourth side wall portion 5) are closed (Fig. 8). The height dimension of the lid flaps 8 and 10 is substantially the same as the distance between each end wall 3 and 5 and the adjacent transverse partition flaps 18 and 20. Therefore, when the lid flaps 8 and 10 of the end walls 3 and 5 are folded in, the upper end surfaces of the lid flaps 8 and 10 are brought into contact with the outer surfaces of the adjacent partition flaps 18 and 20 or positioned adjacent to the outer surfaces thereof. (See FIG. 9).

In the two central compartments 42, 43 sandwiched by the two short partition flaps 18 and 20, preferably an additional cardboard of substantially the same size as each one of the central compartments 42, 43. It is preferable to prepare two boards 60a and one second additional corrugated board board 60b having substantially the same size as the area of the two compartments including the central compartments 42 and 43. First, two first corrugated board 60a are laid on the bottom of each of the central compartments 42 and 43, and the pouch-containing subdividing boxes 50 are stacked on top of them in five layers, and then the other one second corrugated board is used.
The central compartments 42 and 43 are entirely covered with the corrugated board 60b. The two first additional corrugated board 60a and the second
The additional cardboard box 60b and the two central compartments 42, 4
3 into the other compartments 40, 41, 44,
It can be in the same state as the 5-tier stacked box 50 housed in 45. An additional corrugated board 60 (ceiling corrugated board 6) of substantially the same size as the two central compartments 42, 43.
Both side surfaces of 0b) contact the partition flaps 18 or 20 or are located adjacent to and very close to them (see FIG. 9). Next, the long lid flaps 7 and 9 are closed.

According to such a corrugated cardboard box 1, the partition flaps 17 to 20 having a honeycomb structure crossing each other form a support wall extending vertically from the bottom to the lid. Therefore, even if the pouch-containing subdivided boxes 50 are housed in multiple stages, for example, in a stack of 5, it is possible to prevent the lateral movement, and the cardboard boxes 1 accommodating the pouch-containing subdivided boxes 50 are stacked vertically. Even if it is transported by car, the corrugated cardboard box 1 located below is the corrugated cardboard box 1 above it.
It can be prevented from being flattened by being crushed by the load.

Further, in the 10-tier pouch subdivision box 50 in the corrugated cardboard box 1, the gap between the subdivision box 50 located at the uppermost stage and the lid is such that the lid flaps 8 and 10 and the additional corrugated board 60. Since it is filled with (see FIG. 9),
In the illustrated example, it is possible to prevent the five-tiered pouch-containing subdivision boxes 50 from moving up and down in the cardboard box 1.

From the above, the subdivided box 50 containing the pouch
According to the corrugated cardboard box 1 capable of accommodating a plurality of layers, for example, a stack of 5 layers, when the corrugated cardboard box 1 is conveyed, the partition flaps 17 to 20 having a honeycomb structure extending vertically from the bottom to the lid are provided in It is possible to prevent movement, and even if the cardboard boxes 1 are stacked vertically,
The load of the corrugated cardboard box 1 located above is received by the partition flaps 17 to 20 having a honeycomb structure, whereby it is possible to prevent a compressive load from being directly applied to the subdivision box 50 and the pouch 51 therein. it can. The corrugated cardboard box 1 is preferably capable of accommodating the pouch-containing subdivided boxes 50 stacked in less than 10 stages, for example, 3 to 8, and most preferably 5 stages.

It was confirmed that the corrugated cardboard box 1 of the embodiment can withstand a compressive load about twice as compared with the case where the partition flaps 17 to 20 are omitted. Therefore, according to the corrugated cardboard box 1 having the honeycomb structure extending from the bottom to the lid, even if the corrugated cardboard box 1 is made using a relatively inexpensive raw material sheet, the corrugated cardboard boxes 1 are stacked vertically and transported or stored. Also, since it is possible to prevent the cardboard boxes 1 from being deformed by the load of the stacked cardboard boxes 1 and applying a compressive load to the pouch 51 of the contents, a relatively inexpensive raw material sheet is adopted. Therefore, the manufacturing cost of the cardboard box can be reduced.

Further, since the cardboard box 1 can be assembled from one sheet, the manufacturing cost of the cardboard box including the assembly cost can be reduced as compared with the case where a partition different from the cardboard box is prepared. In addition, it is possible to improve workability during assembly.

In addition, the gap between the subdivided box 50 located at the uppermost stage in the cardboard box 1 and the lid is the lid flaps 8 and 10.
Also, since it is filled with the additional corrugated board 60, it is possible to prevent the pouch-containing subdivided boxes 50 stacked in multiple stages from moving up and down in the corrugated board box 1. Further, the lengths of the lid flaps 8 and 10 may be extended to positions beyond the partition flaps 18 and 20.

Using the corrugated cardboard box 1 as described above, the subdivided boxes 50 containing the pouches were accommodated in a state of being stacked in five stages, and the corrugated cardboard boxes 1 were transported in a multi-tiered stack on a vehicle carrier. No pinhole was found on the pouch 51.

In this cardboard box 1, when the food contained in the pouch 51 is relatively heavy, the weight of the content (food) is, for example, 15 if the pouch 51 has the size illustrated above.
It is suitable in the case of 0 g to 230 g. That is, the heavier the food contained in the pouch 51, the greater the possibility of pinholes and bag breakage occurring in the pouch 51, but the use of the cardboard box 1 causes pinholes and bag breakage in the pouch 51. Possibility can be reduced.

The preferred embodiment of the present invention has been described above. However, the present invention is not limited to this. For example, FIG.
As illustrated in 0, the first slit 23 and / or the second vertical slit 24 as the flap insertion means is provided with first and second cutting lines 65, 66 having vertical cutting lines at their ends. May be replaced by these cutting lines 65,
