Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a corrugated cardboard box with a partition plate suitable for storing two bags filled with powder or granules.

[0002]

[Prior art]

 Conventionally, a partition plate has been inserted inside a cardboard box to store a plurality of articles. However, there is no special device for the partition board, and, for example, it is general that a plurality of paperboards are crossed and combined.

[0003]

[Problems to be solved by the device]

 By the way, since the conventional partition plate does not have the effect of suppressing the bulging of the side part of the cardboard box when the article is stored, if the article to be stored is a bag filled with powder, granules, etc. As a result of such deformation, the side surface of the cardboard box bulges. For this reason, the corrugated box and the bag filled with powder and granules are significantly deformed during transportation, etc., and a space is created at the top of the corrugated box, which is mistaken as a lack of volume of powder and granules in the bag. There are also problems that arise.

In view of the above points, an object of the present invention is a step with a partition plate, which is less likely to be deformed even when a bag or the like filled with powder or granules is stored and which can surely pack and protect the stored items inside. To provide a carton.

Other objects and novel features of the present invention will be clarified in the embodiments described later.

[Embodiment of the invention]

 Hereinafter, an embodiment of a cardboard box with a partition plate according to the present invention will be described with reference to the drawings.

1 to 4 show an embodiment of a corrugated cardboard box with a partition plate according to the present invention, in which a corrugated box body 1 and the inside of the corrugated cardboard box body 1 are divided into two regular square pillars. The partition plate 10 forms a space.

As shown in FIG. 1, the corrugated board box body 1 includes four side surface portions, that is, a wide side surface portion 2a which is a front surface and a back surface facing each other, and a narrow side surface portion 2b which is a left and right side surface. It has a wide bent portion 3a and a narrow bent portion 3b formed above and below the portions 2a and 2b, respectively. A dotted line A indicates a bending line (bending position) of each of the bent portions 3a and 3b.

On the other hand, the partition plate 10 made of a corrugated board is composed of a cross section 11 that crosses a position that divides the inside of the corrugated box body 1 into two equal parts, and the cross section in opposite directions on both sides of the cross section 11. 11 is an L-shaped crank and is provided with a creeping portion 12 that is in contact with the inner wall of the wide side surface portion 2a of the corrugated cardboard box body, and three portions including the crossing portion 11 and the two creeping portions 12. It has inner bent pieces 13 formed above and below any two of them (in this example, the crossing portion and the creeping portion on one side). In other words, the inner bent pieces 13 are provided at two places on the upper side and two places on the lower side of the three parts.

Then, as shown in FIG. 2, the bent portions 3 a and 3 b on the bottom surface side of the corrugated board box body 1 are bent and closed. Usually, the narrow bent portion 3b is bent at a right angle to the side surface portion, and then the wide bent portion 3a is bent, and the bottom surface of the corrugated box body 1 is kept closed by an adhesive tape or the like. After that, a necessary part of the partition plate 10 is bent in advance and inserted and arranged inside the corrugated board box body 1. At this time, since the crossing portion 11 is located at a position that divides the width of the wide side surface portion 2a into two, the inside of the corrugated board box body 1 is divided into two equal parts by the partition plate 10 as shown in FIG. Is set to be twice the lateral width of the narrow side surface portion 2b, the two equal-volume internal spaces 20 and 21 partitioned by the partition plate 10 become regular prismatic columns. Further, the inner folding pieces 13 on the lower side of the partition plate 10 are respectively folded along the inner sides of the bottom surfaces of the internal spaces 20 and 21, so that almost the entire area is formed on the bottom portion of the lower folding parts 3a and 3b of the corrugated box body 1. Overlaps (substantially double bottom). Further, each creeping portion 12 is in contact with and reinforced approximately half of the inside of each wide side surface portion.

As shown in FIG. 4, bags 25 filled with powder and granules are housed in the internal spaces 20 and 21 of the same volume partitioned by the partition plate 10, respectively. After the side-folding piece 13 is bent to close the ceiling surfaces (upper surfaces) of the internal spaces 20 and 21, the folding portions 3a and 3b on the ceiling surface side of the cardboard box body 1 are folded and closed as shown in FIG. Normally, the narrow folding portion 3b is bent at right angles to the side surface portion, and then the wide folding portion 3a is bent, and the ceiling surface (upper surface) of the cardboard box body 1 is kept closed by an adhesive tape or the like. At this time, the inner bent pieces 13 on the upper side of the partition plate 10 are folded along the inner side of the ceiling surfaces of the internal spaces 20 and 21, respectively, and are almost located inside the ceiling surface portion formed of the upper bent portions 3a and 3b of the cardboard box body 1. Since it overlaps over the entire area, it has a double ceiling.

According to this embodiment, the following effects can be obtained.

(1) When the bag 25 filled with powder and granules is stored in the two internal spaces 20, 21 obtained by dividing the inside of the cardboard box body 1 by the partition plate 10, the bags 25 on the left and right in FIG. The bulge causes a force pressing the creeping portion 12 of the partition plate 10 and the wide side surface portion 2a of the corrugated cardboard box body 1 in the directions of the arrows P1 and P2, respectively. Since it is a structure that is integrally bent into an L-shaped crank, the pressing force in the direction of arrow P1 applied to the left side contact portion 12 is applied to the right side contact part 12 in the direction of arrow P2. A force in the direction of arrow Q2 that cancels out is generated. Similarly, the pressing force in the direction of arrow P2 applied to the right side creeping portion 12 causes a force in the direction of arrow Q1 that cancels the pressing force of the arrow P1 applied to the left side creeping portion 12. As a result, even if the bag 25 filled with powder or granules is about to be deformed, the partition plate 10 works to suppress the deformation of expanding the side portions 2a of the corrugated box 12 and the wide side surface 2a of the cardboard box body 1 to the outside. , It is possible to reliably protect the items stored inside by packing.

(2) The width of the wide side surface 2a of the cardboard box body 1 is set to twice the width of the narrow side surface 2b, and the partition plate 10 is placed at a position where the width of the wide side surface 2a is divided into two. As a result, the two internal spaces 20 and 21 partitioned by the partition plate 10 can be made into regular square columnar spaces having equal volumes to each other, and a substantially cylindrical powder, a bag filled with granules, and the like. Other cylindrical or prismatic articles can be efficiently stored.

In the above-described embodiment, the upper and lower inner bent pieces 13 of the partition plate 10 are formed so as to be bendable above and below the crossing portion 11 and above and below the one side contact portion 12, respectively. Need only be overlapped with the bottom surface and the ceiling surface of the two internal spaces 20, 21, respectively, so that the upper two positions and the lower side of the three parts consisting of the crossing part 11 and the two contact parts 12 are located. It suffices if they are respectively formed at two locations.

Although the embodiment of the present invention has been described above, it is obvious to those skilled in the art that the present invention is not limited to this and various modifications and changes can be made within the scope of the claims. Ah
