This specification provides a technique for suppressing a handle arranged in a packaging container from falling into the packaging container.

Disclosed herein is a packaging container. A packaging container assembled from a single flat plate, comprising: a main body; a first cover plate bendably connected to the main body; A second cover plate that overlaps upward and is bendably connected to the main body, and a third cover plate that overlaps above the second cover plate and the second cover plate and the main body are connected. An insertion piece that is bendably connected to the second cover plate at the edge opposite to the location with the second cover plate therebetween and is inserted into the main body, and a handle. , the handle portion is connected to a handle base portion arranged on the same flat plate as the second lid plate, and a first handle portion arranged on the same flat plate as the main body, and is connected to the handle base portion via a folding line. at least one end of an end and a second end connected to the handle base via a folding line and arranged on the same flat plate as the insertion piece; The lid plate may have a handle through hole in a portion overlapping the handle portion.

In this configuration, the user inserts his or her finger through the through-hole for the handle, hooks it on the base of the handle, and pulls the base of the handle upward. As a result, at least one of the first end and the second end of the handle is pulled, and the handle is lifted from the handle through-hole above the third cover plate. A first cover plate is arranged below the second cover plate and the handle base. Therefore, it is possible to prevent the handle base from falling into the packaging container. As a result, it is possible to avoid a situation in which it is difficult for the user to pull up the base of the handle.

The handle may comprise the first end and the second end.

By arranging the first end and the second end on each of both ends of the handle, compared to a configuration in which only one of the first end and the second end is arranged , the balance of the packaging container can be improved when the handle is gripped.

The first lid plate includes a contact portion that contacts the handle portion in a state in which the handle portion is pulled upward from the handle through hole, and a portion other than the contact portion and the first lid plate. A pair of cuts may be provided spaced apart between and each extending along the direction in which the handle extends.

When the handle part is pulled up, the contents of the packaging container can be prevented from being exposed by arranging the first cover plate so as to overlap the place where the handle part was arranged before being pulled up. In the above configuration, the first lid plate can be arranged up to a position where it contacts the handle portion in the pulled up state. In this configuration, the contact portion is easily deformed by being pushed by the handle portion by arranging the pair of cuts between the contact portion and the other portion of the first cover plate. As a result, it is possible to prevent damage to the handle due to strong contact between the first cover plate and the handle.

The contact portion may be curved so as to protrude toward the handle portion.

According to the above configuration, it is possible to suppress breakage of the handle portion compared to a configuration in which the contact portion is formed in a straight line.

The second cover plate may have an engagement projection that engages with the upper edge of the main body on the edge on the side where the insertion piece is connected.

According to said structure, it can suppress that a 2nd lid plate falls in a packaging container. Thereby, it is possible to suppress the handle portion arranged on the same flat plate as the second lid plate from falling into the packaging container.

The main body may have an opening penetrating from the inside to the outside of the main body at its lower end.

According to this configuration, the contents of the packaging container can be taken out of the packaging container through the opening.

A deployment body for producing the packaging container described above is also novel and useful.

Of the two partial cover plates 58a, 58a, the partial cover plate 58a arranged closer to the locking piece 34 is provided with a notch 58d for avoiding contact with the locking piece 34. It is

In the packaging container 10, the first cover plate 52, the second cover plate 58, and the third cover plate 56 are stacked in this order from the bottom. In the handle portion 100, the through hole 56a is arranged above the handle base portion 102, and a part of the front-back direction center of the handle base portion 102 is exposed to the outside. A portion of the first cover plate 52 that is sandwiched between the contact portions 52 a in the front-rear direction is arranged below the handle base portion 102 .

As shown in FIG. 6, the user inserts his or her finger through the notch 56b and hooks the finger on the handle base 102. As shown in FIG. A notch 58b is formed in the partial cover plate 58a below the notch 56b. The notch 58b is arranged at a position overlapping the notch 56b. The notches 56b and 58b expose the side surfaces of the handle base 102 so that they can be contacted from above. As a result, the user can easily hook the finger on the handle base 102 . Thereby, the user can easily pull up the handle base 102 .

As shown in FIG. It is folded and angled inwardly of the body 20 with respect to the insert piece 68 . Similarly, as shown in FIG. 8, as the handle base 102 moves, the handle end 106 is bent with respect to the side plate 28 and inclined toward the inside of the main body 20 with respect to the side plate 28 . As a result, the handle portion 100 can be pulled upward.

As shown in FIG. 7, one partial cover plate 58a is placed on the upper edge of the side plate 24 and engaged with the upper edge of the side plate 24 at the end edge of the side where the insertion piece 68 is connected. An engagement projection 58c is arranged. The engaging convex portion 58c protrudes toward the side plate 24 from the edge of the partial cover plate 58a. This can prevent the second cover plate 58 from falling downward. As a result, it is possible to avoid a situation in which the handle portion 100 drops downward along with the second cover plate 58 and the user finds it difficult to pull up the handle portion 100 .

As shown in FIG. 9 , when the handle portion 100 is pulled up and the handle end portion 106 is inclined toward the inside of the main body 20 , the handle portion 100 contacts the contact portion 52 a of the first cover plate 52 . On both sides of the contact portion 52a, a pair of cuts 52b extend in the direction in which the handle portion 100 extends, that is, in the front-rear direction. The distance between the pair of cuts 52b is greater than the length of the handle base 102 in the left-right direction. Therefore, when the contact portion 52 a is brought into contact with the handle portion 100 and pushed, the contact portion 52 a can be easily inclined with respect to other portions of the first cover plate 52 . As a result, it is possible to prevent the contact portion 52 a from strongly abutting the handle portion 100 . When the handle portion 100 is pulled up, a gap is created between the two partial cover plates 58a, 58a. By enlarging the portion of the first cover plate 52 that overlaps the handle portion 100, it is possible to prevent the inside of the main body 20 from being exposed when the handle portion 100 is pulled up. In the packaging container 10, by arranging the contact portion 52a, even if the first lid plate 52 and the handle portion 100 come into contact with each other, the handle portion 100 is not subjected to an excessive load, and the contact portion 52a is not applied to the handle portion 100. 1 The cover plate 52 can be enlarged.

The contact portion 52a contacts the handle portion 100 at the tip on the handle portion 100 side, and does not contact the handle portion 100 at other portions. A portion of the contact portion 52a that contacts the handle portion 100 has a curved shape. Through experiments, it has been found that damage to the handle portion 100 is suppressed as compared with a configuration in which the portion of the contact portion 52a that contacts the handle portion 100 is linear.

A user stores, for example, a powdery substance such as an agricultural dusting agent in the packaging container 10 . A user pulls up the portion surrounded by the notch 32 of the side plate 26 from below to form an opening, grasps the handle 100, and carries the packaging container 10 across a farm such as a field. can be disseminated.

The packaging container 10 is produced from one unfolded body BL1. Thereby, for example, it is not necessary to prepare the handle portion 100 as a separate component.

In the handle portion 100 , handle end portions 104 and 106 are respectively arranged at both ends of the handle portion 100 in the front-rear direction. As a result, the balance of the packaging container 10 is improved when the packaging container 10 is lifted by gripping the handle 100, compared to a structure in which one of the handle ends 104, 106 is arranged on one side of the handle 100 in the front-rear direction. be able to. Further, when the handle portion 100 is pulled upward, the corners between the handle base portion 102 and the handle end portions 104 and 106 are linearly extended, so that the handle portion 100 protrudes above the lid portion 50. can do. By arranging the handle end portions 104 and 106 at both ends of the handle portion 100 in the front-rear direction, respectively, the protruding portion of the handle portion 100 can be increased. Note that, in a modified example, the handle portion 100 may include only one of the handle end portions 104 and 106 .

In the packaging container 10 , the first cover plate 52 is arranged below the second cover plate 58 and the handle portion 100 . This can prevent the second cover plate 58 and the handle portion 100 from falling downward. Therefore, it is possible to avoid a situation in which the handle part 100 is depressed and it becomes difficult for the user to pull it up. According to this configuration, at least one of the handle portion 100 and the second cover plate 58 does not need to be adhered and fixed to the third cover plate 56 or the like in order to prevent the handle portion 100 from falling down. As a result, it is not necessary to use an adhesive or the like to prevent the handle portion 100 from falling down when closing the lid portion 50 after the lid portion 50 is opened and contents are stored in the main body 20 . Although it is possible to prevent the second cover plate 58 and the handle portion 100 from falling downward, at least one of the handle portion 100 and the second cover plate 58 may be fixed to the third cover plate 56 or the like. Moreover, by stacking the first cover plate 52, the second cover plate 58, and the third cover plate 56, it is possible to suppress the deformation of the main body 20 when the handle portion 100 is grasped and the packaging container 10 is lifted. .

A plurality of folding lines 108 c are arranged on the handle base 102 . According to this configuration, the handle base portion 102 is easily bent when the handle portion 100 is pulled up.
