Includes being at right angles and approximately at right angles as long as the above is not lost.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 5 attached.

1 (a) and 1 (b) are diagrams schematically showing a state in which a packaging box 7 and a partition plate 1 according to an embodiment of the present invention are used to partition stored articles. is there.

As shown in FIG. 1A, for example, the pouch-wrapped article B indicated by the alternate long and short dash line is stored in the packaging box 7 in a state of being divided into two by the partition plate 1. Here, the packaging box 7 used is a so-called type A type.

Further, as shown in FIG. 1B, a set of first edge L1 of the partition plate 1 is parallel to the width direction of the packaging box, and a set of second edge L2 is the height of the packaging box. It is parallel to the direction. The side end plate 3 and the side end plate 4 are substantially orthogonal to the surface portion 2 and run parallel to the first side wall portion of the packaging box. As a result, as will be described later, the partition plate 1 is easily fixed to the packaging box.

As shown in FIG. 2A, the partition plate 1 according to the embodiment of the present invention is composed of a centrally located surface portion 2, a side end plate 3, a side end plate 4, a tongue piece 5, and a tongue piece 6. Therefore, the bottom portion 11 of the packaging box 7 is composed of a set of bottom inner flaps 11b and a set of bottom outer flaps 11a. The partition plate 1 is inserted into the packaging box 7 along the direction of the arrow D.

Further, FIG. 2B shows how the partition plate 1 is fixed to the bottom portion 11 of the packaging box 7 as a whole after being inserted into the packaging box 7.

A set of bottom inner flaps 11b of the bottom 11 of the packaging box 7 slightly floats from the set of bottom outer flaps 11a to form a step 12. Further, the tongue piece 5 and the tongue piece 6 of the partition plate 1 are also fixed to the set of the bottom outer flaps 11a, but are slightly floating and not in contact with the set of the bottom outer flaps 11a. Understand.

By adopting such a fixing method, it becomes easy to insert the partition plate 1 into the packaging box 7 and fix it, and the work efficiency is improved.

FIG. 3 is an enlarged view showing in detail how the tongue piece 5 is fixed to the flap 11b in the bottom of the packaging box 7 in FIG. 2 (b), and is an enlarged view showing III in FIG. 2 (b). The part of is shown.

As described above, the tongue piece 5 of the partition plate 1 is formed by the bottom inner flap 11b of the set of packaging boxes 7 at the step 12 with the bottom outer flap 11a of the set of packaging boxes 7. The bottom is not attached to 11a. This is because the edge L7 of the bottom inner flap 11b slightly raised from the bottom outer flap 11a and the vicinity of the bottom of the side upper edge R1 of the tongue piece 5 are pressed against each other, so that the tongue piece 5 is slightly lifted from the bottom outer flap 11a. This is because it is fixed to the edge L7 of the flap 11b in the bottom in the state of being fixed.

At this time, the tongue piece 5 can push the edge L7 of the flap 11b in the bottom because the length of the integrated side end plate 3 is approximately half the length in the length direction of the packaging box. Since the side end plate 3 projects in the direction opposite to the tongue piece 5 and is orthogonal to the surface portion 2 and is parallel to the first side wall portion, the side end plate 3 pushes the second side wall portion of the packaging box. Is. Further, since the length of the tongue piece 5 is approximately half the length of the step 12, the total length of the tongue piece 5 and the side end plate 3 is inside the bottom portion of the packaging box 7 at a position facing the second side wall portion. It is approximately equal to the distance of the flap 11b to the edge L7, and is also for fitting between the edge L7 of the bottom inner flap 11b located at a position facing the second side wall portion. These are the same for the tongue piece 6 and the side end plate 4.

Then, the tongue piece 5 and the tongue piece 6 fix the face portion 2 in the direction in which the tongue piece 5 and the tongue piece 6 are protruding, so that the side end plate 3 and the side end plate 4 are facing in the side end. Since the plates 3 and 4 fix the surface portion 2, the surface portion 2 is hindered from moving, so that the entire partition plate 1 fixes the stored articles without shifting during transportation of the packaging box 7 containing the articles. ..

Although the case where the partition plate 1 has the side end plate 3 and the side end plate 4 has been described, the case where the partition plate 1 has only the tongue piece 5 and the tongue piece 6 without the side end plate 3 and the side end plate 4 The tongue piece 5 and the tongue piece 6, which are oriented in opposite directions and whose length is approximately half the width of the step 12, are larger than the width of the step 12 formed by the set of edges L7 of the flap 11b in the bottom when combined. The tongue piece 5 and the tongue piece 6 are slightly longer than the thickness of the face portion 2, the tongue piece 5 and the tongue piece 6 are fitted into the step 12, and a set of edge L7, the tongue piece 5 and the tongue piece 6 are fixed to each other, and the side end plate 3 and the side Even in the embodiment without the end plate 4, the partition plate 1 is fixed.

FIG. 4 shows a blank sheet 1B of the partition plate 1.

As shown in FIG. 4, the side end plates 3 and the side end plates 4 are connected to both side ends of the face portion 2 via a set of crease lines L2. A notch R1 and a notch R2 are provided at the lower part of the set of crease lines L2, whereby the tongue piece 5 and the tongue piece 6 protruding between the side end plate 3 and the side end plate 4 and the face portion 2 are provided. Each is provided. The tongue piece 5 and the tongue piece 6 are separated from the face portion 2 by the notch R1 and the notch R2, and are integrated with the side end plate 3 and the side end plate 4, respectively.

Here, to explain how to bend the partition plate 1, the partition plate 1 in the state of the blank sheet 1B is formed by the side end plate 3 and the tongue piece 5 and the side end plate 4 and the tongue piece 6 which are integrally integrated with each other. The partition plate 1 as shown in FIG. 1B is obtained by bending the partition plate 1 at a substantially right angle along the ruled line and the notch groove so as to be substantially orthogonal to each other and facing opposite directions.

At this time, the ruled line and the notch groove provided for bending are in a direction substantially orthogonal to the step. As a result, the side end plate 3 and the tongue piece 5 and the side end plate 4 and the tongue piece 6 can be folded at an accurate right angle with respect to the surface portion 2, and high folding accuracy can be obtained. Then, when the blank sheet 1B is bent to create the partition plate 1, it is possible to easily take an appropriate shape for fixing the partition plate 1 without shifting the bending position, and the partition plate can be easily formed inside the packaging box. 1 can be firmly fixed. Further, since it does not take time to bend, work efficiency can be improved.

Further, explaining the side surface shapes of the tongue piece 5 and the tongue piece 6, the side bottoms of the tongue piece 5 and the tongue piece 6 are linear like the lower ends of the side end plates 3 and the side end plates 4. , The upper side edge R1 and the upper side surface R2 of the tongue piece 5 and the tongue piece 6 are curved. This is because when the pouch-wrapped article B is stored in the packaging box 7, the tongue piece 5 and the side upper edge R1 and the side upper edge R2 of the tongue piece 6 are caught, so that the bag is damaged or the work is performed. This is to prevent the efficiency from decreasing.

Here, in FIG. 4 and the like, the side upper edge R1 and the side upper edge R2 of the tongue piece 5 and the tongue piece 6 are curved, but when the pouch-wrapped article B is stored in the packaging box 7. The side surface shape may be triangular or trapezoidal as long as the upper parts of the tongue piece 5 and the tongue piece 6 are not caught.

When the partition plate 1 does not have the side end plate 3 and the side end plate 4 and only the tongue piece 5 and the tongue piece 6 are integrally provided on the face portion 2, the blank sheet has a set of crease lines. The tongue piece 5 and the tongue piece 6 connected to L2 are in a state of protruding from the surface portion 2. By bending the protruding tongue piece 5 and the tongue piece 6 so as to be substantially orthogonal to the surface portion 2 and facing in opposite directions, the partition plate 1 having no side end plate 3 and side end plate 4 can be obtained.

When the partition plate 1 has the side end plate 3 and the side end plate 4, the blank sheet 1B of the partition plate 1 has no protrusion to the outside of the partition plate 1 as shown in FIG. 4, and is a single corrugated cardboard. Since it is made of a sheet, the material cost can be suppressed as compared with the case where the protruding portion is formed by cutting off the other part while leaving the necessary part of the corrugated cardboard sheet.

FIG. 5 shows a blank sheet 7B of the packaging box 7.

As shown in FIG. 5, the blank sheet 7B of the packaging box 7 has a second side wall portion 9 connected to the first side wall portion 8 via a body crease line L3 and a bottom crease line L4. It has a bottom outer flap 11a connected via a bottom outer flap 11a, a bottom inner flap 11b connected via a second side wall portion 9 and a bottom crease line L5, and an adhesive portion 10.

After folding the body crease line L3 of the side wall of the blank sheet 7B of the packaging box, the adhesive portion 10 is adhered to the second side wall 9, and a set of the bottom outer flap 11a and the bottom inner flap 11b are folded to the outside of the bottom. By fixing the flap 11a with adhesive tape or staples, a square-body type packaging box 7 having a body portion 13 shown in FIG. 1A is completed.

At this time, as described above, the folded set of the bottom inner flaps 11b are not in contact with each other, a gap is formed between the edges L7 of the bottom inner flaps, and the folded and fixed set of the bottom outer flaps is folded. A step 12 is formed between the vehicle and the product 11a. Further, the edge L7 of the bottom inner flap is slightly raised because it is not fixed to the set of bottom outer flaps 11a constituting the bottom of the step 12. By using this step 12, the tongue piece 5 and the tongue piece 6 of the partition plate 1 and the edge L7 of the set of flaps in the bottom can be fixed to each other.

Here, a procedure for packing the pouch-wrapped article B in the packaging box 7 will be described with reference to FIGS. 1 to 5.

First, as described above, the blank sheet 1B shown in FIG. 4 is folded into a partition plate 1, and the packaging box 7 is assembled from the blank sheet 7B shown in FIG. Next, as shown in FIG. 2A, the partition plate 1 is inserted into the packaging box 7 along the arrow D. At this time, as shown in FIGS. 2B and 3, in the step 12, the tongue piece 5 and the tongue piece 6 of the partition plate 1 are placed on the edge L7 of the flap 11b in the bottom of the tongue piece 5 and the tongue piece 6. The vicinity of the bottom of each of the side surface upper edge R1 and the side surface upper edge R2 is fixed, and the bottom outer flap 11a is slightly lifted. After the partition plate 1 is fixed, the pouch-wrapped article B is stored in each of the partitioned parts of the packaging box 7. Then, the state shown in FIG. 1 (a) is obtained. After storage, close the upper inner flap and outer flap of the packaging box 7 and fix them with adhesive tape or staples. Then, the packaged pouch-wrapped article B is transported in a state of being stored in the packaging box 7.

After the transportation is completed and the stored items are taken out, the partition plate 1 is released from the fixed state and taken out from the packaging box 7.

In such a procedure, the blank sheet 1B may be folded to form the partition plate 1, and the partition plate 1 can be inserted and fixed into the packaging box 7 by a simple procedure as described above. , Preparation for storing articles is not troublesome, and work efficiency can be improved.

Further, when the partition plate 1 and the packaging box 7 are discarded after the article is taken out after transportation, the partition plate 1 is only bent, so that it can be easily discarded by returning it to the blank sheet state again and putting it together. be able to.

As described above, according to the embodiment of the present invention, the packaging box 7 is provided by using the partition plate 1 including the face portion 2, the side end plate 3, the side end plate 4, the tongue piece 5, and the tongue piece 6. The partition plate 1 can be fixed before the goods are stored in the box, and the stored items do not move during transportation. Further, since the partition plate 1 is completed by simply bending it and can be easily inserted into the packaging box 7 and fixed to the step 12, it does not require labor for assembling, inserting and fixing, and improves work efficiency. ..
