Description

TECHNICAL FIELD The present invention relates to a partition plate for partitioning packaging boxes.

Conventionally, in a packaging box for storing bagged goods, the interior of the packaging box is divided into two along the long side of the packaging box at the time of storage, and the goods are packed in each part of the divided packaging box. are being stored. At this time, a partition plate is generally used to divide the interior into two with respect to the long sides of the packaging box.

As such partition plates, there are those in which a simple flat plate is inserted, and those in which a single flat plate is bent into a Z shape and inserted. Since they are not rigidly secured, there is a risk that the bagged items may move within the packaging box during transport and damage the bag. Furthermore, when inserting the partition plate after the bagged items are put in, it is necessary to carefully insert the partition plate along the shape of the packed items so as not to damage the bag itself. There is also the problem of reduced efficiency.

As an invention for solving such problems, in Patent Document 1, a filling plate is provided at the bottom of a single flat plate that is bent in a Z shape, and the bottom inner flap and the bottom outer flap of the packaging box are attached to each other. An invention is described in which the partition plate is fixed by filling the step.

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

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

As shown in FIG. 1( a ), for example, a pouch-packaged article B indicated by a chain double-dashed line is housed in a packaging box 7 in a state of being divided into two by a partition plate 1 . The packaging box 7 used here is of the so-called A type.

Also, as shown in FIG. 1(b), the pair of first edges L1 of the partition plate 1 is parallel to the width direction of the packaging box, and the pair of second edges L2 is the height of the packaging box. parallel to the direction. The side end plate 3 and the side end plate 4 are substantially perpendicular to the surface portion 2 and extend parallel to the first side wall portion of the packaging box. Thereby, as will be described later, the partition plate 1 is easily fixed to the packaging box.

As shown in FIG. 2( a ), the partition plate 1 of the embodiment of the present invention consists of a central surface portion 2 , side end plates 3 , side end plates 4 , tongues 5 , and tongues 6 . The bottom 11 of the packaging box 7 consists of a set of inner bottom flaps 11b and a set of outer bottom flaps 11a. The partition plate 1 is inserted along the direction of arrow D into the packaging box 7 .

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

A pair of bottom inner flaps 11b of the bottom portion 11 of the packaging box 7 forms a step 12 slightly above the pair of bottom outer flaps 11a. Furthermore, the tongues 5 and 6 of the partition plate 1 are also fixed to the pair of bottom outer flaps 11a, but are slightly lifted from the pair of bottom outer flaps 11a and are not in contact with each other. Recognize.

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

FIG. 3 is an enlarged view showing in detail how the tongue 5 is fixed to the bottom inner flap 11b of the packaging box 7 in FIG. shows the part of

As described above, the tongue 5 of the partition plate 1 is positioned at the step 12 between the bottom inner flaps 11b of the pair of packaging boxes 7 and the bottom outer flaps 11a of the pair of packaging boxes 7. 11a is not bottomed. This is because the edge L7 of the bottom inner flap 11b, which is slightly lifted from the bottom outer flap 11a, and the vicinity of the bottom of the side upper edge R1 of the tongue 5 press against each other, so that the tongue 5 is slightly lifted from the bottom outer flap 11a. This is because it is fixed to the edge L7 of the bottom inner flap 11b in the folded state.

At this time, the tongue piece 5 can push the edge L7 of the bottom inner flap 11b only when the length of the integrated side end plate 3 is approximately half of the length in the longitudinal direction of the packaging box. , projecting in a direction perpendicular to the surface portion 2 in a direction opposite to the tongue 5 and extending parallel to the first side wall portion, the side end plate 3 pushes the second side wall portion of the packaging box. is. In addition, 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 within the bottom portion of the packaging box 7 facing the second side wall portion. This is also because it is approximately equal to the distance to the edge L7 of the flap 11b and fits between the edge L7 of the bottom inner flap 11b opposite the second side wall. These are the same for the tongues 6 and the side end plates 4 as well.

The tongue 5 and the tongue 6 fix the surface portion 2 in the direction in which the tongue 5 and the tongue 6 protrude, so that the side end plate 3 and the side end plate 4 face in the direction in which the side end plate 3 and the side end plate 4 face. By fixing the surface part 2 by the plates 3 and 4, the movement of the surface part 2 is prevented, 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 plates 3 and 4 has been described, the case where the partition plate 1 does not have the side end plates 3 and 4 and has only the tongues 5 and 6 , the tongues 5 and 6 facing in opposite directions and having a length approximately half the width of the step 12, when combined, are wider than the width of the step 12 formed by a pair of edges L7 of the bottom inner flap 11b. The tongue 5 and the tongue 6 are fitted into the step 12, and the set of edge L7 and the tongue 5 and the tongue 6 are fixed to each other, and the side end plate 3 and the side In embodiments without end plates 4, the partition plate 1 is also fixed.

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

As shown in FIG. 4, side end plates 3 and 4 are connected to both side ends of the face portion 2 via a pair of folding lines L2. A notch R1 and a notch R2 are provided in the lower part of the set of fold lines L2. provided respectively. The tongues 5 and 6 are separated from the surface portion 2 by the cuts R1 and R2, and are integrated with the side end plates 3 and 4, respectively.

Here, the method of folding the partition plate 1 will be described. 1(b), the partition plate 1 shown in FIG.

At this time, the creases and cut grooves provided for folding are in a direction substantially perpendicular 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 accurately folded substantially perpendicularly to the surface portion 2, and high folding accuracy can be obtained. Then, when the blank sheet 1B is folded to create the partition plate 1, the shape suitable for fixing the partition plate 1 can be easily obtained without shifting the bending position, and the partition plate can be formed inside the packaging box. 1 can be firmly fixed. Furthermore, since it does not take time to bend, it is possible to improve work efficiency.

Also, explaining the side shapes of the tongues 5 and 6, the bottoms of the sides of the tongues 5 and 6 are linear like the lower ends of the side end plates 3 and 4, whereas the bottoms of the side end plates 3 and 4 are linear. , the upper side edge R1 and the upper side edge R2 of the tongue 5 and the tongue 6 are curved. This is because the upper side edge R1 and the upper side edge R2 of the tongue 5 and the tongue 6 are caught when the pouch-packaged article B is put into the packaging box 7, which may damage the bag or cause work problems. This is to prevent a decrease in efficiency.

Here, in FIG. 4 and the like, the upper side edge R1 and the upper side edge R2 of the tongue 5 and tongue 6 are curved. As long as the tops of the tongues 5 and 6 are not caught, the side shape may be triangular or trapezoidal.

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 surface portion 2, the blank sheet has a set of folding 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 tongues 5 and 6 so as to be substantially orthogonal to the surface portion 2 and facing in opposite directions, the partition plate 1 without the side end plates 3 and 4 can be formed.

As shown in FIG. 4, the blank sheet 1B of the partition plate 1 when the partition plate 1 has the side end plate 3 and the side end plate 4 has no projecting portion outside the partition plate 1, and is a piece of corrugated cardboard. Since it is made of a sheet, the material cost can be reduced compared to the case where the projecting portion is formed by cutting off the rest of the corrugated cardboard sheet while leaving the necessary portion.

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

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 the trunk fold line L3 and a bottom fold line L4. It has a bottom outer flap 11a connected via the second side wall portion 9, a bottom inner flap 11b connected via the bottom folding line L5, and an adhesive portion 10. As shown in FIG.

After folding the trunk folding line L3 of the side wall of the blank sheet 7B for packaging, the adhesive part 10 is adhered to the second side wall 9, and a pair of bottom outer flaps 11a and bottom inner flaps 11b are folded to fold the bottom outer part. By fixing the flaps 11a with an adhesive tape or staples, a square-shaped packaging box 7 having a body portion 13 shown in FIG. 1(a) is completed.

At this time, as described above, the set of folded bottom inner flaps 11b are not in contact with each other, and a gap is formed between the edges L7 of the bottom inner flaps, and the set of folded and fixed bottom outer flaps is formed. A step 12 is generated between the 11a. In addition, the edge L7 of the bottom inner flap is not fixed to the pair of bottom outer flaps 11a forming the bottom of the step 12, so it is slightly raised. By using this step 12, the tongues 5 and 6 of the partition plate 1 and the edge L7 of the pair of bottom inner flaps can be fixed to each other.

Here, the procedure for packing the pouch-packaged article B into the packaging box 7 will be described with reference to FIGS. 1 to 5. FIG.

First, as described above, the blank sheet 1B shown in FIG. 4 is folded to form the partition plate 1, and the packaging box 7 is assembled from the blank sheet 7B shown in FIG. Next, the partition plate 1 is inserted into the packaging box 7 along the arrow D as shown in FIG. 2(a). At this time, as shown in FIGS. 2(b) and 3, within the step 12, the tongues 5 and 6 of the partition plate 1 are attached to the edge L7 of the bottom inner flap 11b. The vicinity of the bottom of each side upper edge R1 and side upper edge R2 is fixed and slightly lifted from the bottom outer flap 11a. After the partition plate 1 is fixed, the pouch-packaged article B is stored in each partitioned portion of the packaging box 7 . Then, the state shown in FIG. 1(a) is obtained. When storage is completed, the upper inner flap and outer flap of the packaging box 7 are closed and fixed with adhesive tape or staples. Then, the packed pouch-packaged article B is transported while being stored in the packaging box 7. - 特許庁

After transportation is finished and the stored items are taken out, the fixed state of the partition plate 1 is released and the items are taken out from the packaging box 7.例文帳に追加

In such a procedure, the partition plate 1 can be formed by folding the blank sheet 1B, and the insertion and fixing of the partition plate 1 into the packaging box 7 can be performed by the easy procedure as described above. The work efficiency can be improved without making preparations until the articles are stored.

Further, when the partition plate 1 and the packaging box 7 are discarded after the article is taken out after transportation, since the partition plate 1 is merely folded, it can be easily discarded by returning it to the state of a blank sheet and putting it together again. be able to.

As described above, according to the embodiment of the present invention, by using the partition plate 1 having the surface portion 2, the side end plate 3, the side end plate 4, the tongue piece 5, and the tongue piece 6, the packaging box 7 can be The partition plate 1 can be fixed before the articles are stored in the container, so that the stored articles do not move during transportation. In addition, the partition plate 1 can be completed simply by folding, and can be easily inserted into the packaging box 7 and fixed to the step 12, so that labor for assembling, insertion and fixing is not required, and work efficiency is improved. .

In addition, this invention is not limited to embodiment mentioned above, and its modification.

For example, the side end plate 3 and the side end plate 4 may be provided with notches so that the tongues 5 and 6 fit into the gap between the edges L7 of the pair of bottom inner flaps.
