Description

  The present invention relates to a polygonal packaging container.

  Conventionally, rectangular packaging containers such as cubes and rectangular parallelepipeds have been widely used. Since such a packaging container is easy to assemble and can be stacked without any gap, it is preferably used in a wide range of fields such as storage and logistics. In particular, these packaging containers made of corrugated paper are not only light and inexpensive, but are also very widely used because they are durable.

  However, depending on the shape of the contents, such a rectangular container may be inappropriate. For example, when the contents have a round shape such as a pizza pie or cake, an unnecessary space, so-called dead space, is formed in the inside of the container, particularly in the corner of the container. If such a space is present inside the container, the stability of the contents may be deteriorated, and the contents may be damaged due to the contents moving in the box during transportation.

  In order to prevent such an accident, for example, when packing round contents into a rectangular container, a packing such as a box with a triangular prism shape that fits the corner of the container is used. Putting them into the corners or packing rolled newspapers into the gaps of the containers is performed. However, such work is troublesome and causes unnecessary waste.

In order to solve such a problem, for example, a container having a polygonal shape has been proposed (see, for example, Patent Document 1). By using such a container, the problem of dead space when a round-shaped content is stored is solved. Therefore, it is possible to safely transport the luggage without using the filling inside the container.
JP 58-29914 A

  Since the container having a polygonal shape has a large number of sides constituting the bottom surface, the number of side walls provided along the side of the bottom surface of the container is increased. Therefore, when creating such a polygonal container, as shown in the development view of the container described in Patent Document 1, one or more peripheral walls are provided on the bottom plate of the container, and the peripheral wall is erected. In general, individual side walls are formed by bending along the side of the bottom plate of the container. In this case, the end portions of the peripheral walls are finally engaged with each other to form the last side wall and prevent the container from being disassembled.

  However, in a container with such a structure, there is no problem if the contents are light, such as pizza pie or cake, but if the contents are heavy, the contents move and collide with the engaging portion of the container. In this case, the ends of the peripheral walls may be disengaged and the container may be disassembled. Further, even when an impact is applied to the container from the outside, such as when the container is dropped, the ends of the peripheral walls may be disengaged and the container may be disassembled. In these cases, the contents are discharged from the container when the container is disassembled, which causes problems such as damage to the contents.

  The present invention has been made in view of the above situation, and an object thereof is to provide a polygonal packaging container capable of preventing the container from being disassembled even when an impact is applied to the container. And

A first engagement piece is provided at each of at least one pair of end portions located at the end of the peripheral wall, and at least one of the side walls forms a pair. The at least one pair of end portions are not formed with the side walls, and a pair of second engaging pieces for preventing the first engaging pieces from being disengaged are connected. It is provided.

  (2) It is preferable that the second engaging pieces forming a pair engage with each other on the surface of the bottom plate.

  (3) It is preferable that the second engaging pieces forming a pair can be engaged when a convex portion is provided on one of the pair and a concave portion is provided on the other.

  (4) Preferably, a connecting back plate is provided on one side of the bottom plate, and a lid is formed through the connecting back plate.

  (5) It is preferable that the side wall formed by engaging the pair of first engagement pieces exists on the side of the bottom plate on which the connection back plate is provided.

  (6) It is preferable that a first flap for contacting the lid and a second flap for contacting the bottom plate are connected to at least one side wall.

  (7) Embrace the side wall with a winding plate extending from one side of the bottom plate, and fit a fitting portion formed at the tip of the winding plate into a fitting hole formed in the bottom plate. Is preferred.

  (8) There are two peripheral walls, and the two peripheral walls are provided with end pieces at the other end of the first engagement piece, respectively, and the two end pieces are combined to form a side wall. It is preferable that the side wall is embraced by the winding plate.

  (9) The bottom plate is preferably octagonal.

It is preferable from the viewpoint of maintaining the strength. Further, it is particularly preferable to use a double cardboard made of two flutes among the cardboards.

  As a method of manufacturing the container 1, the corrugated cardboard blank is punched into a corrugated cardboard blank, and the corrugated cardboard blank is processed into a developed shape of the container 1, and then a press machine equipped with a mold is used. A method of creating a crease by applying pressure to a portion that becomes a folded portion when assembling the container 1 is exemplified. In this case, it is preferable to perform press punching for simultaneously performing punching and pressing on the corrugated cardboard blank in terms of simplifying the work process. Instead of punching the corrugated cardboard blank, laser cutting may be performed.

  The container 1 is provided such that an octagonal bottom plate 2 and two peripheral walls 3 connected to the bottom plate 2 can stand up so that the bottom plate 2 is sandwiched therebetween. That is, the peripheral wall 3 is provided in a state in which at least a part thereof is connected to the bottom plate 2 so as to be able to stand upright.

  Since the width direction of the peripheral wall 3 becomes the height direction of the container 1 when the container 1 is assembled, the length in the width direction of the peripheral wall 3 may be determined according to the desired height of the container 1. Since the width direction of the connecting back plate 8 also becomes the height direction of the container 1 when the container 1 is assembled, the length of the connecting back plate 8 in the width direction is determined according to the desired height of the container 1. . Therefore, the length in the width direction of the peripheral wall 3 and the length in the width direction of the connecting back plate 8 are substantially the same. Here, “substantially the same” means that the dimensions of each part must be determined in consideration of the thickness of the cardboard, but are the same when the thickness of the cardboard is ignored.

  As described above, two peripheral walls 3 are provided, and a part of the peripheral wall 3 is connected to the bottom plate 2 so as to be able to stand upright. That is, each peripheral wall 3 is provided in a state where one side of the bottom plate 2 is shared. Then, by folding one side of the bottom plate 2 that the peripheral wall 3 shares with the bottom plate 2, the peripheral wall 3 rises and three side walls 4 are formed. The length direction of the side wall 4 is substantially the same as the length of one side of the bottom plate 2, and the side wall 4 having a size corresponding to each side of the bottom plate 2 is formed along each side of the bottom plate 2.

  First engagement pieces 6a and 6b are provided at a pair of ends located at the ends of the two peripheral walls 3, respectively. And the side wall is formed when the 1st engagement piece 6a and the 1st engagement piece 6b mutually engage.

Provided. That is, the second engaging pieces 7a and 7b forming a pair are provided with a convex portion on one of the pair and a concave portion on the other. By combining these convex portions and concave portions, the second engaging pieces 7a and 7b are engaged with each other.

  The second engagement pieces 7 a and 7 b are folded into the container 1 when the first engagement pieces 6 a and 6 b are engaged, and engage with each other on the surface of the bottom plate 2. For this reason, unlike the first engagement pieces 6a and 6b, the second engagement pieces 7a and 7b do not form side walls. That is, the second engagement pieces 7a and 7b are engaged with each other at a position different from that of the first engagement pieces 6a and 6b.

  As described above, the second engaging pieces 7a and 7b forming a pair engage with each other when the first engaging pieces 6a and 6b forming a pair are engaged. Since the first engaging pieces 6a and 6b are connected to the second engaging pieces 7a and 7b, respectively, the first engaging pieces 6a and 6b are engaged by the second engaging pieces 7a and 7b engaging with each other. Is fixed, and disengagement of the first engagement pieces 6a and 6b is prevented.

  In the container 1, when two peripheral walls 3 are arranged on the left and right, a connecting back plate 8 is provided on the side that is the innermost part of the bottom plate 2, and a lid 5 is provided via the connecting back plate 8. The lid 5 has the same octagonal shape as the bottom plate 2 and is substantially the same size as the bottom plate 2. The lid 5 is provided with insertion pieces 17 on every other side with reference to the side of the lid 5 on which the connection back plate 8 is provided. Accordingly, a total of three insertion pieces 17 are provided on the lid 5.

When arranged, the bottom plate 2 is formed on the side that is the innermost part. That is, the side wall formed by the engagement of the first engagement pieces 6a and 6b exists on the side of the bottom plate 2 on which the connection back plate 8 is provided.

  Of the six side walls 4 that are formed on the two peripheral walls 3 from the beginning, the four side walls 4 that do not share the side of the bottom plate 2 are respectively connected to the first flap 9 and the bottom plate 2 for contacting the lid 5. A second flap 10 is formed for contact with. All the first flaps 9 and the second flaps 10 are folded inside the container 1 when the container 1 is assembled, and contact the lid 5 and the bottom plate 2, respectively.

  A winding plate 11 extending from the bottom plate 2 is provided on the side of the bottom plate 2 that faces the side of the bottom plate 2 on which the connecting back plate 8 is provided. Since the winding plate 11 is used for embedding and fixing the side wall, the winding plate 11 is substantially twice as long as the width direction of the peripheral wall 3. A fitting portion 12 is formed at the front end of the winding plate 11, and the winding plate 11 is fixed in an upright state by fitting the fitting portion 12 into a fitting hole 13 provided in the bottom plate 2. .

  Of the two peripheral walls 3, end pieces 16 and 16 are provided at the other ends of the first engaging pieces 6a and 6b. The end pieces 16 and 16 are combined with each other to form a side wall. However, since the end pieces 16 and 16 do not have means for engaging with each other, the formed side wall is not fixed. For this reason, the side wall which consists of the end pieces 16 and 16 is fixed in the standing state by being embraced in the winding board 11 and the fitting part 12 provided in the winding board 11 being fitted in the fitting hole 13.

Therefore, when the container 1 is covered with the lid 5, if only the side of the lid 5 that faces the side having the connecting back plate 8 is fixed to the winding plate 11 with a tape or the like, the lid 5 is completely fixed, and can prevent the container 1 from being opened due to an impact or the like. For this reason, even if not fixing all the sides of the lid 5 with tape, it is only necessary to fix with one tape among the sides of the lid 5, so that the labor of the packing operation is greatly reduced.

  Further, the side wall formed by the engagement of the pair of first engagement pieces 6 a and 6 b exists on the side of the bottom plate 2 on which the connection back plate 8 is provided. Therefore, in the state where the container 1 is covered, the side wall formed by the engagement of the first engagement pieces 6 a and 6 b is covered and protected by the connecting back plate 8. Therefore, in the state where the container 1 is covered, an impact is applied to the portion of the side wall formed by engaging the first engagement pieces 6a and 6b from the outside, or the heavy object stored in the container 1 moves. Even if an impact is applied to the side wall formed by the engagement of the first engagement pieces 6a and 6b, the engagement portions of the first engagement pieces 6a and 6b are protected by the connecting back plate 8, The container 1 is prevented from being disassembled.

  Of the six side walls 4 that are formed on the two peripheral walls 3 from the beginning, the four side walls 4 that do not share the side of the bottom plate 2 are each provided with a first flap 9 for contacting the lid 5 and A second flap 10 for contacting the bottom plate 2 is connected. Therefore, when the container 1 is assembled, the four second flaps 10 overlap the bottom plate 2 and the bottom plate 2 is reinforced. Therefore, the container 1 is prevented from being decomposed when a heavy object is stored in the container 1.

  Further, a winding plate 11 extending from the bottom plate 2 is provided on the side of the bottom plate 2 that faces the side of the bottom plate 2 on which the connecting back plate 8 is provided, and the first engagement piece of the two peripheral walls 3 is provided. A side wall formed by combining end pieces 16 and 16 existing at the other ends of 6a and 6b is embraced by the winding plate 11. Therefore, the side wall composed of the end pieces 16, 16 is fixed in an upright state and is protected by the winding plate 11. Therefore, when a shock is applied from the outside to the side wall portion formed by combining the end pieces 16, 16, or a heavy object stored in the container 1 moves, the side wall formed by combining the end pieces 16, 16 Even if an impact is applied to the portion, the container 1 is prevented from being disassembled.
