Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a packaging box with partitions in which the box body is divided into a plurality of sections by partition plates.

[Prior art] When storing items such as bottles in this type of packaging box,
Widely used is an automatic insertion device that grasps multiple items at once with a clamp, releases the clamps above each compartment separated by a partition plate, and inserts the items into each compartment. .

When inserting items into each compartment in the box body using such an automatic insertion device, if you want to ensure that the items are inserted into each compartment, the upper part of each compartment must be inserted when the clamp is released. The bottom part of the item must be inserted.

On the other hand, partitions used in packaging boxes for products such as bottles do not need to have the same height as the bottle;
The height of the body of the bottle is sufficient.

However, the height of the partition plate inserted into the box body in relation to the automatic insertion device is approximately the same as the height of the cylindrical side wall of the packaging box.

[Problem to be solved by the invention] To improve the reliability of automatically inserting items into a packaging box with a partition plate, or to reduce the amount of thick paper such as cardboard used for forming the partitions while maintaining the reliability.

[Means for Solving the Problems] In order to solve the above problems, this invention consists of a box body and a partition inserted into the box body, and the box body is divided into a rectangular cylindrical side wall and a partition body inserted into the box body. It is formed by a bottom wall provided on the lower edge of the cylindrical side wall and four lid flaps provided on the upper edge of the cylindrical side wall, and the above-mentioned partition body is connected by the bottom wall to form at least two lid flaps that stand up. A first partition plate having a partition wall and a flat second partition plate
The first partition plate and the second partition plate are formed by fitting slits provided in both so that the first partition plate is suspended from the second partition plate, and the first and second partition plates are The height dimension is lower than the side wall of the box main body, and the second partition plate is provided with a protrusion at the side end that can lock the partition in a suspended manner at the upper part of the box main body. .

[Operation] A partition is inserted into the box main body, and the partition is suspended in the upper part of the box main body through contact between the cylindrical side wall and the projecting piece.

When the article clamped by the clamp section of the automatic article insertion machine is inserted into each compartment divided by the partitions, the moment when the bottom of the article contacts the top surface of the bottom wall of the first partition plate. Then, the first partition plate is pushed in, and the second partition plate is dragged by the first partition plate, and the partition body is lowered together with the goods.

[Example] In the figure, A is a partition body formed of thick paper such as cardboard to be inserted into the box body B.

The above-mentioned partition A includes a first partition plate 3 having at least two partition walls 2 connected by a bottom wall 1 and standing upright, and a flat second partition plate 4. 4, the first partition plate 3 is formed by fitting the slits 5 provided on both sides so that the first partition plate 3 is suspended, and the height dimensions of the first and second partition plates 3, 4 are set as a box. A projecting piece 6 lower than the side wall of the main body B and at the side end of the second partition plate 4 is provided to suspend the partition A at the upper part of the inside of the box main body B.
is provided.

The slit 5, in which the first partition plate 3 is suspended from the second partition plate 4, extends from the lower edge of the partition wall 2 across the bottom wall 1, as shown in FIGS. 1 to 5. The slits 5 are provided facing upward and downward from the upper edge of the second partition plate 4, and can be assembled by inserting both slits 5 so as to mesh with each other.

Further, as shown in FIGS. 3 and 4, the protruding pieces 6 are made to protrude from the lower part of both side edges of the second partition plate 4 in a row, and the protruding pieces 6 are fitted into the embankment hole 7 of the box body B. , when the lower edge of the projecting piece 6 is engaged with the lower edge of the embankment hole 7 to receive the partition A, and when the lower edge of the projecting piece 6 is engaged with the lower edge of the embankment hole 7, and as shown in FIG. There are two cases: a case in which tapered protrusions 6 with increasing amounts are connected to push the peripheral wall apart and stop due to frictional resistance, and a case in which the protrusions 6 are engaged with the upper edge of the peripheral wall of the box body B (not shown). be.

Furthermore, the box body B has a rectangular cylindrical side wall 11 and a bottom wall 1 provided at the lower edge of this cylindrical side wall 11.
2 and four lid flaps 13 provided on the upper edge of the cylindrical side wall 11.

The packaging box with partitions according to this invention has the above structure, and how to use it will be explained next.

First, insert the partition A into the box body B, and
The partition body A is stopped at the top of the box body B via a protruding piece 6.

Therefore, when an item clamped by the clamp section of the automatic item insertion machine is inserted into each compartment divided by the partition A, the bottom of the item comes into contact with the top surface of the bottom wall 1 of the first partition plate 3. From this point on, the first partition plate 3 is pushed in, and the second partition plate 4 is dragged by the first partition plate 3, and when the clamp of the article is released, the partition body A descends together with the article.

Further, even if the clamp of the article is released before the lower surface of the article comes into contact with the upper surface of the bottom wall 1 of the first partition plate 3, the partition A can be pushed through the article in the same manner as described above.

As described above, according to the packaging box with partitions according to this invention, the partition can be inserted into the packaging box and locked to the upper part of the packaging box through the protrusion, so that the partition can be automatically inserted. When an item is inserted by the machine, the lower part of the item can be reliably inserted into each compartment of the partition by the slight downward stroke of the automatic insertion machine, and as the item is lowered, the bottom of the item and the first partition are The second partition plate can be dragged through the first partition plate that descends by contacting the upper surface of the bottom wall of the plate, and the second partition plate can be dragged through the descending first partition plate. The resistance reduces the rate of descent of the item (due to its own weight) and prevents damage or breakage of the item.

Therefore, the article can be inserted reliably.

Moreover, since the height dimensions of the first and second partition plates are made lower than the side walls of the box body, it is possible to save materials and reduce costs.

Furthermore, as the lifting stroke of the automatic insertion machine is shortened, the efficiency of inserting items can be improved.
