A packaging box having a lid plate and capable of storing light-weight sachet-packed foods, confectionery, and other products side by side is known (see, for example, Patent Document 1).

The packaging box is provided with a pair of cut lines that go around the tubular body, and a cut band portion formed between the pair of cut lines is cut off and the upper half portion is removed to remove the lower half portion. The product stored in the box can be displayed in a state that can be seen by consumers.

Japanese Unexamined Patent Publication No. 2006-27660

However, in the packaging box described in Patent Document 1, in order to make the product stored in the lower half portion visible to the consumer by removing the upper half portion, it is necessary to make the product visible to the consumer between the pair of cut lines. It is necessary to cut off the formed cut band portion, and there is an inconvenience that it takes time to remove the upper half portion.

It is an object of the present invention to provide a packaging box capable of eliminating such inconvenience and performing an operation of removing the upper half portion in a short time.

In order to achieve such an object, the packaging box of the present invention has a cylindrical body extending in the height direction consisting of a rear plate, a pair of side plates, and a front plate facing the rear plate, and the tubular body. It is a packaging box that has a bottom plate that closes the bottom of the cylinder, a lid plate that closes the top of the cylinder, and a cut line that goes around the cylinder, and can store products packed in sachets side by side. The cut line formed on the side plate runs diagonally upward from above the center in the height direction of the portion where the side plate is connected to the rear plate toward the front plate, and diagonally downward in front of the front plate. The apex of the ridge is connected to the cut line formed on the front plate by forming a chevron shape biased toward the side view front plate, and the cut line formed on the front plate is such that the side plate is on the front plate. It runs diagonally downward along the extension line of the cut line formed on the side plate from the connecting portion, and is characterized in that it is connected at the central portion.

The packaging box of the present invention is suitable for opening while tilting from a vertically placed state in which the front plate is attached to the floor side to a flat placed state in which the bottom plate is attached to the floor side with the boundary line between the front plate and the bottom plate as a rotation axis. ..

That is, when the operation of removing the upper half of the packaging box of the present invention is performed, the lower half of the packaging box in the vertically placed state is held by the operator and the boundary line between the front plate and the bottom plate is used as the rotation axis. By tilting the half part to the floor side, the upper half part and the lower half part are separated from each other, and the cut line is broken from the rear plate side.

At this time, in the packaging box of the present invention, the side plate of the lower half portion after being broken at the cut line is above the center in the height direction of the packaging box, that is, even for the product stored in the packaging box. Since the side wall is higher than half in the height direction, it is possible to reduce the possibility of the product spilling even if the upper half is started to be removed from the vertical installation state.

In addition, since the cut line formed on the side plate of the packaging box runs diagonally upward toward the front plate, the front plate that serves as the base among the many products stacked inside the packaging box in the vertical installation state. The product on the side can be supported by the higher side wall, and the possibility of the product spilling can be reduced even if the upper half is started to be removed from the vertical installation state.

Therefore, in the packaging box of the present invention, the product can be easily lifted in a very short time by simply rotating the packaging box from the vertical installation state to the flat installation state with the boundary line between the front plate and the bottom plate as the rotation axis. Half can be removed.

Further, in the packaging box of the present invention, it is preferable that the position of the apex in the front-rear direction coincides with the rear end of the product stored in the front row of the products or is arranged on the front plate side thereof.

According to the packaging box having this configuration, among the many products stacked inside the packaging box in the vertical installation state, the product in the front row, which is the base, is at least one of the side walls of the lower half of the packaging box. Since it is supported at the highest point, it is possible to further reduce the possibility of product spilling even if the upper half is started to be removed from the vertical position, so it is possible to remove the upper half more quickly and easily in a very short time. can.

Here, the paper pattern 11 has a grain in the direction in which the rear plate 2, the first side plate 3, the front plate 4, the second side plate 5, and the side plate glue margin piece 5a are connected to each other, and the first cut line 9 is formed. Is formed along the grain direction.

When making the packaging box 1 using the paper pattern 11, first, the first side plate 3, the front plate 4, the second side plate 5, and the side plate glue margin piece 5a are formed along the crease lines 12, 13, 14, and 15. The tubular portion 6 shown in FIG. 1 is formed by bending to the inner side of the packaging box 1 and attaching the side plate glue margin piece 5a to the side surface opposite to the first side plate 3 inside the rear plate 2. do.

Next, along the crease lines 16, 17, 18, and 19, the first bottom plate piece 7a, the second bottom plate piece 7b, the third bottom plate piece 7c, and the fourth bottom plate piece 7d are placed inside the packaging box 1. The first bottom plate glue margin piece 7e is attached onto the first bottom plate piece 7a, and the second bottom plate glue margin piece 7f is attached onto the third bottom plate piece 7c. Then, the first bottom plate piece 7a and the second bottom plate piece 7b attached via the first bottom plate glue allowance piece 7e, and the third bottom plate adhesive piece 7f attached via the second bottom plate glue allowance piece 7f. The bottom plate 7 is formed by combining the bottom plate piece 7c and the fourth bottom plate piece 7d.

Next, the lid receiving pieces 2a and 4a and the lid plate 8 are bent toward the inside of the packaging box 1 along the crease lines 22, 23 and 24, and the lid plate 8 is positioned on the lid receiving pieces 2a and 4a. To do. Then, the insertion piece 8a is bent toward the inside of the packaging box 1 along the crease line 8b and inserted into the inside of the first side plate 3, whereby the packaging box 1 shown in FIG. 1 is completed.

Next, when performing an operation of removing the upper half of the packaging box 1, first, the front plate 4 is placed on a desk, floor, or the like and placed vertically. Then, the operator presses the finger insertion portion 10 formed on the rear plate 2 of the packaging box 1 shown in FIG. 1 inward with the fingers of one of the left and right hands. In this way, the shallow V-shaped first cut line 9 and the second cut line 10a surrounding the finger insertion portion 10 are broken, while the finger insertion portion 10 becomes the crease line 2b. Along the inside of the packaging box 1, it is bent and opened.

Therefore, the operator grasps the fold line 2b side of the finger insertion portion 10 with the fingers of one of the left and right hands (explained by taking the left hand as an example), and the other hand (explained by taking the right hand as an example). Grasp the portion where the first cut line 9 on the opposite side of the crease line 2b of the finger insertion portion 10 is broken.

Next, the left hand is not moved while being gripped, and the right hand is moved in the direction of bringing the bottom plate 7 closer to the floor side with the boundary line between the front plate 4 and the bottom plate 7 as the rotation axis, and the fingers of both hands are moved to the sides separated from each other. ..

In this way, the first cut line 9 formed on the first side plate 4 and the second side plate 6 is torn from the rear plate 2 side and gradually broken.

At this time, the first side plate 4 and the second side plate 6 remaining on the lower half portion 1b side are above the center in the height direction of the packaging box 1 (even with respect to the product G stored in the packaging box 1). Since it is a side wall (higher than half in the height direction), the product G does not easily spill even if the upper half portion 1a is started to be removed from the vertical installation state.

Further, since the first cut line 9 formed on the first side plate 4 and the second side plate 6 of the packaging box 1 runs diagonally upward toward the front plate, the packaging box 1 is placed vertically. Of the large number of commodities G piled up inside, the commodities G on the front plate side, which is the base, are supported by the higher side wall. In particular, the apex of the first cut line 9 formed on the first side plate 4 and the second side plate 6 forming the chevron shape is the product G whose position in the front-rear direction is stored in the front row of the product G. Since it coincides with the rear end, the product G in the front row, which is the base of the most foundation, is supported at the highest part of the side wall of the lower half portion 1b at least in part. Therefore, even if the upper half portion 1a is started to be removed from the vertical installation state, the product G is unlikely to spill.

Further, when the bottom plate 7 is moved closer to the floor side by moving the right hand, the first cut line 9 of the front plate 4 becomes the first cut line 9 formed on the first side plate 4 and the second side plate 6. Since it is formed along the extension line, it is smoothly broken from the side edge side toward the center.

Finally, the front plate 4 is bent in two by the portion extending in the horizontal direction at the center of the shallow U-shaped portion of the first cut line 9 formed on the front plate 4 as the rotation axis. The character portion is broken and the upper half portion 1a is removed.

As described above, in the packaging box 1, the product G is simply towed by the right hand so as to rotate the packaging box 1 from the vertical installation state to the flat installation state with the boundary line between the front plate 4 and the bottom plate 7 as the rotation axis. The upper half 1a can be easily removed in a very short time without spilling.

As a result, as shown in FIG. 3, it is possible to make the product G, such as food or confectionery in a pouch, contained in the lower half portion 1b left after the upper half portion 1a is removed so as to be visible to the consumer. can.

In the above embodiment, the apex of the first cut line 9 formed on the first side plate 4 and the second side plate 6 forming the chevron is located in the front row of the product G in the front-back direction. Although the one that coincides with the rear end of the stored product G has been described as an example, it is more preferable that this apex is arranged on the front plate side of the rear end of the product G.

Further, in the above embodiment, the first cut line 9 formed on the front plate 4 is connected to a shallow U-shaped portion in the central portion, but the central portion may extend linearly in the horizontal direction. , It may run diagonally downward along the extension line of the first cut line 9 formed on the first side plate 4 and the second side plate 6 to the center, and may be formed in a V shape as a whole.

Further, in the above embodiment, for the sake of facilitation of explanation, the description has been made on the premise that the left hand is not moved, but the present invention is not limited to this. Half portion 1a may be removed.
