Description

  The present invention relates to a packaging container.

  Currently, paper packaging containers are widely used for packaging ampoules and the like in medicine. The packaging container is folded so as not to be bulky at the time of disposal and is collected as waste. However, such a packaging container requires a folding operation requiring labor and force, such as peeling off the strongly glued portion or forcibly breaking the side surface. Thus, a structure that facilitates folding has been proposed (Patent Document 1).

  As shown in FIG. 10, the packaging container shown in Patent Document 1 is provided with a paper zipper 958 on one diagonal line of the bottom surface 918 and further provided parallel folds 954 and 956 on the other diagonal side. Yes. As shown in FIG. 11, after the zipper 958 is torn and cut from the center to both ends as shown in FIG. 11, the bottom 918 is pulled out to the front as shown in FIG. 12, and the folds 954 and 956 are projected and folded. It is out.

(Configuration of packaging container 100)

  In the packaging container which concerns on one Embodiment, the perspective view of the state which opened the upper cover surface is shown in FIG. The box-shaped packaging container 100 includes six surfaces, which are an upper lid surface 12, a bottom surface 10, a back surface 11, a front surface 13, a right side surface 14, and a left side surface 15. On the front surface 13, an opening break line 39 that breaks at the time of opening is formed. Further, the upper lid surface 12 is provided with a flap 36.

  The packaging container 100 has a configuration as shown in a development view of FIG. First, the upper lid surface 12 on the left side of the packaging container 100 shown in the figure is provided with adhesive surfaces 33 and 32 on the upper and lower sides, and folding lines 38 and 37 are formed at these joint portions. Further, as described above, the upper lid surface 12 is provided with the flap 36 on the left side, and the crease line 27 is formed at these joint portions.

  Next, the upper lid surface 12 is joined to the rear side 11 on the right side, and a crease line 24 is formed at these joined portions. A left side 15 and a right side 14 are provided above and below the back surface 11 in this figure, and crease lines 22 and 23 are formed at these joints. Further, a flap 35 is provided at the upper end edge of the left side surface 15, and a crease line 26 is formed at these joint portions. Furthermore, the lower end edge of the right side surface 14 is provided with a flap 34, and a crease line 25 is formed at these joints.

  Furthermore, the bottom surface 10 is joined to the right side of the back surface 11, and a crease line 21 is formed at these joint portions. At the top and bottom of the bottom surface 10, there are provided paste pieces 31 and 30, and crease lines 19 and 20 are formed at the respective joint portions.

Furthermore, the front surface 13 is joined to the right side of the bottom surface 10, and a crease line 18 is formed at these joints. Side covers 17 and 16 are provided above and below the front surface 13, and crease lines 29 and 28 are formed at these joints. The above-mentioned crease lines 18 to 29 and fold break lines 37 and 38 are all folded at a 90 ° angle by mountain folds. Here, the unsealing break line 39 and the folding break lines 37 and 38 are formed such that the broken cut line segments and the connecting line segments connecting the cut line segments appear alternately.
(Structure of the bottom surface 10)

Next, FIG. 3 shows as an enlarged plan view only the bottom surface of the packaging container in the above embodiment. As shown in this figure, the bottom surface 10 has a substantially rectangular shape, and each broken line is formed diagonally. The bottom surface 10 of this figure forms a first break line 40 in a diagonal line from the upper left corner to the lower right corner. Further, the bottom surface 10 extends a second break line 41 that bisects the inner angle at the upper right corner from the corner to the first break line 40. The angle α formed by the second break line 41 and the first break line 40 is 90 ° or more on the central portion side of the first break line 40. Further, the bottom surface 10 extends a second break line 42 that bisects the inner angle at the lower left corner from the corner to the first break line 40. The angle α formed by the second break line 42 and the first break line 40 is 90 ° or more on the central portion side of the first break line 40. However, the break line is not limited to the above-described configuration, and the left and right sides can be interchanged. That is, in the embodiment of FIG. 3, the first break line is extended from the upper left to the lower right, and the second break line is extended from the upper right and the lower left, respectively, toward the first break line. The breaking line may be from the upper right to the lower left, and the second breaking line may be extended from the upper left and the lower right to the first breaking line.
(First break line 40)

The first break line 40 and the second break lines 41 and 42 are formed such that the cut line segments that are broken and the connecting line segments that connect the cut line segments appear alternately. Further, as shown in the plan view of FIG. 3, the first break line 40 has a center cut line segment 40A at the center, corner break line portions 40D and 40E at both ends, and further, the center cut line segment 40A and the corner break line. Between the line parts 40D and 40E, it has the fracture | rupture line parts 40B and 40C. In FIG. 3, the corner break line portion 40D, the break line portion 40B, the central cut line segment 40A, the break line portion 40C, and the corner break line portion 40E are arranged in a straight line in this order.
(Center cut line segment 40A)

  The central cut line segment 40A is obtained by inserting only a cut line segment with a certain length at the central part of the diagonal first break line 40. The central cut line segment 40A is formed longer than the other cut line segments. By providing the central cut line segment 40A, the operator can break the entire first break line 40 by pressing the finger in contact with the vicinity of the central cut line segment 40A. In particular, in the vicinity of the central cut line segment 40A, if the cut line segment is made long and the connecting line segment is made short as described later, the entire first break line 40 can be easily broken even with a weak pressing force.

In the embodiment of FIG. 3, the dimension AL of the central cut line segment 40A is about 20 mm. In this embodiment, the length of the first break line 40 is about 260 mm, and the center cut line segment 40A is provided at about 8% of the center. However, this numerical value is only an example, and the first cut of the central cut line segment 40A is taken into consideration in consideration of the dimensions of the packaging container, the paper material, the thickness, the strength, the weight of the stored items and the required strength. The ratio in the break line can be changed as appropriate, and preferably the length of the central cut line segment can be adjusted in the range of 5 to 20% with respect to the total length of the first break line. If it is less than 5%, it is necessary to press more strongly in the vicinity of the central cut line 40A in order to break the entire first break line 40, and if it exceeds 20%, the strength as the bottom member cannot be maintained. An object may fall.
(Corner break line 40D, 40E)

  Moreover, the 1st broken line 40 forms the fixed area and corner broken line part 40D, 40E from each edge part of a diagonal line, as shown in FIG. The corner break line portions 40D and 40E also repeat the connecting line segment and the cut line segment alternately. Thus, a packaging container suitable for automatic assembly by a box making machine can be obtained.

  The packaging container can be adapted for automatic assembly by a box making machine. The box making machine takes the packaging container in the unfolded state shown in FIG. 2 and automatically assembles it into the assembled state shown in FIG. When the diagonal break line is formed on the bottom surface of the packaging container and the box making machine is passed with the same ratio of the connecting line segment and the cut line segment, the perspective view (a) in FIG. As shown to b), the distortion part 50 which swelled in the vicinity of a fracture line arises in the corner part in the bottom face of the packaging container assembled, and becomes defective. Therefore, in the present embodiment, in the vicinity of the end portion of the first break line 40, the connecting line segment is made longer than the cut line segment, thereby increasing the strength of the corner portion, thereby assembling the packaging container 100 with the box making machine. However, the deformation of the corner can be prevented.

The dimension CL of the corner break line portions 40D and 40E in the embodiment shown in FIG. 3 is about 40 mm. In this embodiment, the length of the corner break line portions 40D and 40E is about 15% of the total length of the first break line 40 of about 260 mm. The corner break line portions 40D and 40E have a length shorter than the distance from the intersections P1 and P2 between the first break line 40 and the second break lines 41 and 42 to the end of the first break line 40. The shape of the corner break line portions 40D and 40E is about 3 mm in the length of the connecting line segment and about 1.5 mm in the length of the cut line segment, and is repeated in the section of the dimension CL. By setting in this way, it is possible to prevent the corner from being deformed during assembly by the box making machine. The lengths of the corner break line portions 40D and 40E and the ratio between the connecting line segment and the cut line segment are not limited to the above, and the material and strength of the packaging container used, the required strength, etc. Although it can set suitably according to it, Preferably, the ratio of a corner fracture line part can be set in 10 to 20% of range with respect to the full length of a 1st fracture line. If it is less than 10%, deformation during box making tends to occur, and if it exceeds 20%, derailment from the broken line portion tends to occur. Furthermore, the length of the connecting line segment in the corner break line portion can be set in a range of 150 to 250% with respect to the length of the cut line segment. If it is less than 150%, deformation during box making tends to occur, and if it exceeds 250%, derailment from the fracture line tends to occur.
(Break line 40B, 40C)

  Furthermore, break line portions 40B and 40C are formed between the central cut line segment 40A and the corner break line portions 40D and 40E in the first break line 40. The broken line portions 40B and 40C are formed at a ratio in which the connecting line segment is shorter than the cut line segment, and thus the break can be easily continued from the central cut line segment 40A. In the broken line portions 40B and 40C in this embodiment, the length of the connecting line segment is approximately 1.5 mm and the length of the cut line segment is approximately 3 mm. By setting the length of the connecting line segment to a ratio of about half of the length of the cut line segment, the connecting line segment can be broken by being pressed with a weak pressing force. However, the length and ratio are not limited to the above, and can be appropriately changed depending on the dimensions of the packaging container to be created, the thickness of the paper, and the like. Preferably, the length of the connecting line segment can be set in a range of 25 to 75% with respect to the length of the cut line segment. If it is less than 25%, it will break due to impact from the outside due to transportation, and if it exceeds 75%, it will be difficult to break.

As described above, the first break line 40 includes the lengths of the connecting line segments and the cut line segments in the break line portions 40B and 40C near the center, and the connecting line segments in the corner break line portions 40D and 40E near the end portions. Each length with the cut line segment is reversed. Here, the break line portions 40B and 40C pass through the intersections P1 and P2 with the second break lines 41 and 42 and extend to the contact points with the corner break line portions 40D and 40E. Further, the break line portions 40B and 40C are formed so that the length of the cut line segment is longer than the connecting line segment (in the embodiment in FIG. 3, it is approximately doubled). Accordingly, the break line portions 40B and 40C can be easily broken, and the corner break line portions 40D and 40E continuous with the break line portions 40B and 40C can be easily broken from the break line portions 40B and 40C at a stretch. That is, when the operator presses the vicinity of the center cut line segment 40A, the break line portions 40B and 40C whose cut line segments are longer than the connecting line segments are changed from the center cut line segment 40A to the corner break line portions 40D and 40E. It is easily broken towards. Further, the corner break line portions 40D and 40E are inherently less likely to break than the break line portions 40B and 40C, and the momentum at which the break line portions 40B and 40C are broken from the center side toward the end side is transmitted. As a result, it is continuously broken as it is. As described above, the first break line 40 can easily prevent the break line portions 40B and 40C adjacent to each other while increasing the strength of the corner break line portions 40D and 40E at the end portions to prevent deformation during assembly by the box making machine. By increasing the breakability, at the time of disposal, the break line portion 40B, 40C is continuously broken into the corner break line portions 40D, 40E so that the break operation can be performed.
(Second break line 41, 42)

  Next, the second break lines 41 and 42 of the bottom surface 10 are formed at an angle that bisects the interior angle from each end portion that forms a diagonal line different from the diagonal line provided with the first break line 40 as described above. One broken line 40 is provided. The second break lines 41 and 42 are formed such that the ratio between the connecting line portion and the cut line segment is uniform in the length direction. For example, the second break line can be uniformly repeated from the end portion to the first break line at a ratio in which the length of the cut line segment is shortened with respect to the length of the connecting line segment.

  The second break lines 41 and 42 of this embodiment are formed so that the lengths of the connecting line segment and the cut line segment are substantially equal. The shape of the second break lines 41 and 42 in this form repeats a length of the connecting line segment of about 3 mm and a length of the cut line segment of about 3 mm. However, the lengths of the connecting line segment and the cut line segment in the second break lines 41 and 42 are not limited to this, and can be appropriately changed according to the dimensions of the packaging container 100 to be created, the thickness of the paper, and the like. .

Further, the cut line segments of the second break lines 41 and 42 are formed to be substantially equal to the lengths of the cut line segments in the break line segments 40B and 40C of the first break line 40. The second break line segments 41 and 42 form cut line segments longer than the connecting line segments of the break line segments 40B and 40C, and the lengths of the cut line segments and the connecting line segments of the second break line segments 41 and 42 are set. By equalizing, it can be bent easily. On the other hand, as shown in FIG. 3, the second break lines 41 and 42 are joined to the break line portions 40B and 40C at the intermediate intersections P1 and P2. The first breaking line 40 having such a structure is broken at a stretch through the breaking line portions 40B and 40C by pressing near the center, passes through the intersections P1 and P2, and continuously breaks to the corner breaking line portions 40D and 40E. Is done. In particular, the broken line segments 40B and 40C are not changed in the ratio of the cut line segment and the connecting line segment before and after the intersections P1 and P2 with the second broken lines 41 and 42, and more than the second broken lines 41 and 42. Since the connecting line segment is shortened, it is easier to break. Therefore, the second break lines 41 and 42 are relatively less likely to be broken and are easily bent instead. In this embodiment, the lengths of the cut line segments of the second break lines 41 and 42 and the cut line segments of the break line segments 40B and 40C are both about 3 mm, but the present invention is not limited to this. The length of the cut line segment can be appropriately changed depending on the dimensions of the packaging container 100 to be created, the thickness of the paper, and the like.
(Assembly method of packaging container 100)

Here, a method of assembling the packaging container 100 into a box shape will be described with reference to FIG. First, the surrounding crease lines 21, 22, 23, 24 on the back surface 11 are bent at 90 ° by mountain folding. Next, the paste pieces 30, 31, 32, 33 are applied with glue on the surface, and the crease lines 19, 20 and the fold break lines 37, 38 are folded at 90 ° into the right side surface 14 and the left side. Affixed to the back surface of the surface 15. Further, the flaps 34, 35, and 36 are bent at 90 ° by folding the crease lines 25, 26, and 27. Next, the front surface 13 is bent at 90 ° by folding the crease line 18 into mountains. Thereafter, the side covers 16 and 17 positioned at both ends of the front surface 13 are glued on the back surface, and are folded at 90 ° by folding lines at the crease lines 28 and 29, so that the right side surface 14 and the left side surface 15 Pasted on the outside. Thereby, the packaging container 100 is formed in a box shape. For this reason, the packaging container 100 needs to store the stored items before the front surface 13 is closed.
(How to open the packaging container 100)

The assembled box-shaped packaging container 100 is opened when the packaged contents are used. In this unsealing method, the unsealing break line 39 formed on the front surface 13 is broken so that a finger can be put on the flap 36, and then the upper lid surface 12 is pulled up together with the flap 36. At that time, the glued pieces 32 and 33 glued to the right side surface 14 and the left side surface 15 are separated from the upper lid surface 12 by breaking the folding break lines 37 and 38. Thereby, the paste pieces 32 and 33 are held in a state of being glued to the side surfaces 14 and 15.
(Method of folding packaging container 100)

  On the other hand, the folding method of the packaging container 100 at the time of disposal is demonstrated with the perspective view of FIGS. 4 is a perspective view of the bottom surface of the packaging container shown in FIG. 1, FIG. 5 is a perspective view of the packaging container of FIG. 4 broken along the first breaking line, and FIG. 6 is a perspective view of the packaging container of FIG. FIG. 7 is a perspective view of the folded state of the packaging container of FIG. 6, and FIG. 8 is a perspective view of the folded state of the upper cover surface of the packaging container of FIG. ing.

  First, in FIG. 4, in order to fold the packaging container 100, the bottom surface 10 is directed upward and the vicinity of the center of the bottom surface 10 is easily pressed.

  Next, FIG. 5 shows a state in which the first break line 40 is slightly broken by the operator pressing the vicinity of the center of the bottom surface 10 of the packaging container 100 with a finger. The first breaking line 40 is provided with a central cut line segment 40A that has already been cut at the center. By pressing here, the broken line portions 40B and 40C at both ends of the central cut line segment 40A start to break. Thereby, the 1st breaking line part 40 can be broken by pressing even with a weak force.

  Further, in FIG. 6, by further pressing the central portion of the bottom surface 10 in the packaging container 100, the first break line 40 is broken to the end, and the second break line parts 41 and 42 are starting to bend into valley folds. Indicates the state. The second break lines 41 and 42 are repeatedly formed with substantially equal lengths of the connecting line segment and the cut line segment. As described above, the second break lines 41 and 42 are connected to the break line portions 40B and 40C at the intermediate intersections P1 and P2. By pressing the vicinity of the center, the first break line 40 breaks linearly from the break line portions 40B and 40C, which are easily broken, to the corner cut line portions 40D and 40E. On the other hand, the second break lines 41 and 42 extending from the intersection points P1 and P2 on the break line portions 40B and 40C are not broken by the press but are folded into valley folds.

  Furthermore, in FIG. 7, the state which folded the packaging container 100 is shown. The packaging container 100 can accommodate the bottom surface 10 inside the packaging container 100 because the first breaking line 40 is all broken and the second breaking lines 41 and 42 are folded into valley folds. As a result, the folded packaging container 100 is substantially flat and can have as few protrusions as possible, and is not bulky when collected as waste.

  Furthermore, in FIG. 8, the state which folded the upper cover surface 12 of the packaging container 100 is shown. This packaging container 100 can also fold the upper lid surface 12 together with the flap 36 to the front surface 13 side as needed. Thereby, since the upper cover surface 12 and the flap 36 overlap with the front surface 13 side, it can be made more compact and waste can be more easily collected. The folding method of the upper lid surface 12 and the flap 36 is not limited to mountain folding, and can be folded as valley folding.

  As described above, the packaging container 100 can easily fold the bottom surface 10 into the packaging container 100 in a short time simply by increasing the thickness in the vicinity of the center of the bottom surface 10, thereby shortening the time required for disposal. it can.
