  Hereinafter, a packaging box according to an embodiment of the present invention will be described with reference to the drawings. In the following embodiments, the same reference numerals are given to the same components.

(First embodiment)
As shown in FIG. 1, the packaging box 1 according to the present embodiment includes a main body 10 that forms an accommodation space that accommodates an object to be packaged, and a sheet 20 that partitions the accommodation space.
Here, below, a packaging target object is demonstrated as a board | substrate.

  The main body 10 is made of a resin such as polyethylene or polypropylene. The main body 10 includes a bottom plate 11 on which the substrate is placed, a cylinder 12 that accommodates the substrate, a first fixing member 13 that fixes the bottom plate 11 to the cylinder 12, and a lid plate that covers the substrate accommodated in the cylinder 12 14 and a second fixing member 15 that fixes the cover plate 14 to the cylindrical body 12.

The bottom plate 11 is a rectangular plate-like member, and is a member that supports the substrate accommodated in the cylindrical body 10. One end of the bottom plate 11 is connected to a later-described first side wall plate 121 of the cylindrical body 12 by a hinge.
Further, the free end 111 of the bottom plate 11 is connected to the first fixing member 13 by a hinge.

  The cylindrical body 12 is formed by arranging four side wall plates 121 to 124 in four directions. Hereinafter, these four side wall plates are referred to as a first side wall plate 121, a second side wall plate 122, a third side wall plate 123, and a fourth side wall plate 124. In FIG. 1 and FIG. 2, the first side wall plate 121 and the third side wall plate 123 are hidden and are not directly visible, and therefore the lead lines are indicated by broken lines.

  The first side wall plate 121 is connected to the third side wall plate 123 and the fourth side wall plate 124 by a hinge. Further, the second side wall plate 122 is connected to the third side wall plate 123 and the fourth side wall plate 124 by a hinge. That is, the side wall plates 121 to 124 are connected to adjacent side wall plates by hinges. As described above, the first side wall plate 121 is connected to one end portion of the bottom plate 11 by a hinge.

  Two hook-and-loop fasteners 3 a and 4 a are attached to one surface of the second side wall plate 122. The hook-and-loop fasteners 3a and 4a are members called by names such as Velcro (registered trademark) and Velcro (registered trademark). The same applies to other hook-and-loop fasteners described later.

  The first fixing member 13 is a member that fixes the bottom plate 11 to the cylindrical body 12. As described above, one end of the bottom plate 11 is connected to the first side wall plate 121 of the cylindrical body 12. Therefore, the bottom plate 11 can be fixed to the cylindrical body 12 by connecting the free end 111 of the bottom plate 11 to the second side wall plate 122. As a result, the opening of the cylindrical body 12 facing the bottom plate 11 is covered with the bottom plate 11.

  A hook-and-loop fastener 3 b is attached to one surface of the first fixing member 13. The hook-and-loop fastener 3b is a member that engages with the hook-and-loop fastener 3a.

  The hook-and-loop fastener 3b is attached to a position that engages with the hook-and-loop fastener 3a in a state where the free end 111 of the bottom plate 11 is connected to the second side wall plate 122. And the bottom plate 11 is fixed to the cylinder 12 by the hook-and-loop fastener 3a and the hook-and-loop fastener 3b engaging.

  The cover plate 14 is a rectangular plate-like member, and is a member that covers the cylindrical body 12 from the side opposite to the bottom plate 11. Of the four end portions of the cover plate 14, one end portion 141 is connected to the first side wall plate 121. And the end part 141 and the 1st side wall board 121 are connected with the hinge. Therefore, the cover plate 14 is formed so as to be swingable with respect to the cylindrical body 12 around the hinge. Further, the free end 142 of the cover plate 14 with the end 141 is connected to the second fixing member 15. The free end 142 and the second fixing member 15 are connected by a hinge. Therefore, the second fixing member 15 is formed to be swingable with respect to the cover plate 14 around the hinge.

  The second fixing member 15 is a member that fixes the cover plate 14 to the cylindrical body 12. Here, the end portion 141 of the cover plate 14 is connected to the cylindrical body 12. Therefore, if the free end 142 of the cover plate 14 is connected to the second side wall plate 122, the cover plate 14 can be fixed to the cylindrical body 12 as shown in FIG.

  Similar to the first fixing member 13, a surface fastener (not shown) is attached to one surface of the second fixing member 15 shown in FIG. 1. This hook-and-loop fastener is attached to a position where it engages with the hook-and-loop fastener 4a in a state where the free end 142 of the lid plate 14 is connected to the second side wall plate 122. Then, when a hook-and-loop fastener (not shown) attached to the second fixing member 15 is engaged with the hook-and-loop fastener 4a, the cover plate 14 is fixed to the cylindrical body 12 as shown in FIG. Then, the opening of the cylindrical body 12 facing the cover plate 14 is covered with the cover plate 14.

  Then, the bottom plate 11 covers the opening on one end side of the cylindrical body 12 shown in FIG. 1, and the cover plate 14 covers the opening on the other end side of the cylindrical body 12, so that the accommodation space is closed as shown in FIG.

  The sheet 20 shown in FIG. 1 is formed of a foamed resin sheet made of polyethylene, polypropylene, or the like, a bubble cushioning material, or the like, and is a member that holds a substrate housed in the housing space of the main body 10. Here, the bubble cushioning material is a member called by a name such as an air cap (registered trademark) or bubble wrap (registered trademark).

Four sheets 20 are arranged in the accommodation space formed by the main body 10 with an interval D therebetween.
One end of each sheet 20 is fixed to the inner wall of the third side wall plate 123 so that the first side wall plate 121 and the second side wall plate 122 are parallel to each other. It is fixed to the inner wall of the side wall plate 124.

The interval D of the sheets 20 is set to a size that can accommodate and hold the thinnest one of the substrates 2 in this example, which is to be stored in the storage box 1.
Moreover, the sheet | seat 20 has the size W larger than the size L of the front horizontal direction of the storage box 1 originally, as shown to Fig.3 (a). In the initial state, the sheet 20 is arranged in a state where it is folded in three along the folding lines FL1 and FL2 in the width direction as shown in FIG.

  The size of the seat 20 in the horizontal direction after folding is equal to L, and as shown in FIG. On the other hand, the width W of the sheet 20 is set in accordance with the maximum size of the product to be accommodated. When the maximum size has a thickness 2 · D, as shown in FIG. 5, the length W of the sheet 20 can accommodate the substrate 2A of the maximum size, can accommodate the substrate 2A between the two sheets 20, and A large empty space is not formed between the two sheets 20, and the size is set such that the two sheets 20 can hold the substrate 2 </ b> A.

  1, 3 </ b> B, and 4, the sheet 20 is simply folded for easy visual recognition, but the folded sheets 20 overlap with a relatively weak conductive adhesive. The parts may be bonded and adhered to form a single sheet. In this case, as shown in FIG. 5, when the thick substrate 2 </ b> A is accommodated in the packaging box 1, the folded sheet 20 may be peeled off and used as a sheet having a width W.

  Next, the usage method of the packaging box 1 which has the said structure is demonstrated. First, from the state shown in FIG. 1, the bottom plate 11 is closed, and the hook-and-loop fasteners 3a and 3b are fixed to each other.

  Here, when the substrate 2 having the reference thickness is accommodated, the substrate 2 is inserted between the adjacent sheets 20 as shown in FIG. The substrate 2 is held by the sheet 20, another substrate 2 accommodated in the main body 10, and the like in a standing state. However, since the seat 20 serves as a cushion, a situation where the seats 20 collide with each other does not occur.

  On the other hand, as shown in FIG. 5, when accommodating the relatively thick substrate 2 </ b> A, a part of the folded sheet 20 is expanded to form a space for accommodation between the two sheets 20.

  According to the above configuration, the horizontal length of the sheet 20 has an extra length. Therefore, as shown in FIG. 4 and FIG. 5, it becomes possible to accommodate the accommodation in the accommodation space formed by the main body 10 regardless of the thickness of the accommodation.

  Further, the four side wall plates 121 to 124 are respectively connected to adjacent side wall plates by hinges. Each of the bottom plate 11 and the cover plate 14 is also connected to only one side wall plate 121 that forms the cylindrical body 12. Therefore, as shown in FIG. 6, the packaging box 1 is formed by bending the corners 5 and 6 of the pair of diagonal portions into acute angles and obtuse the corner portions 7 and 8 of the other pair of diagonal portions as shown in FIG. It can be folded into a plate shape after being folded into two. Thereby, when the packaging box 1 is stored, the storage space for storing the packaging box 1 can be made smaller than when the packaging box 1 is stored without being folded.

  Furthermore, about the used packaging box 1 in a folded state, the corners 5 to 8 are bent at a right angle, and as shown in FIG. 1, the cylindrical body 12 is formed into a cylindrical shape so that it can be reused. Become. When the packaging box 1 is reused, the sheet 20 is tri-folded again as necessary.

  In addition, this invention is not limited to said embodiment, A various deformation | transformation and application are possible.

  For example, the main body 10 does not have to be formed of resin as long as it forms an accommodation space for accommodating the substrate 2, and may be formed of, for example, a corrugated cardboard material or a foamed resin. However, when a cardboard material is used, a piece of cardboard material may adhere to the substrate 2 accommodated in the accommodation space. And when handling the board | substrate 2 conveyed by the packaging box 1 in the clean room of a factory, it is not preferable to bring the board | substrate 2 which such a piece of paper adhered into the clean room. Therefore, when handling the board | substrate 2 in the clean room of a factory, it is preferable to form the main body 10 with resin.

  Moreover, when forming the main body 10 with foamed resin, in order to protect the board | substrate 2 from the impact at the time of transport, it is preferable that the foaming ratio of foamed resin is about 2-3 times.

  Furthermore, you may prevent the electrostatic breakdown of the board | substrate 2 by forming the main body 10 and the sheet | seat 20 from a conductor. Specifically, when the material forming the main body 10 is a cardboard material, electrostatic breakdown of the substrate 2 may be prevented by using a liner containing carbon. Moreover, when the material which forms the main body 10 is resin, the electrostatic breakdown of the substrate 2 may be prevented by reducing the surface resistivity by including a surfactant on the surface of the resin.

  In addition, the sheet 20 does not need to be formed from the bubble cushioning material as long as the substrate 2 can be sandwiched, and may be formed from, for example, cloth or resin. In addition, although the sheet | seat 20 was folded in three and arrange | positioned in the accommodation space of the main body 10, since it is necessary to fold as flat as possible, it is desirable to select as thin a material as possible. Furthermore, although the board | substrate 2 was inserted between the adjacent sheets 20 and the board | substrate 2 was clamped by the sheet | seat 20 and it will be in the standing state, the board | substrate 2 may be leaned on the sheet | seat 20 and may be in the standing state.

  As long as the packaging object can be accommodated in the accommodating space of the main body 10, anything such as a glass product or a medicine kit may be used. Further, the packaging object may be one in which a coil, a capacitor, or the like is mounted on the substrate as long as it can be accommodated in the accommodating space of the main body 10.

  The bottom plate 11 is connected to the first side wall plate 121 by a hinge. However, if the bottom plate 11 can be fixed to the cylindrical body 12, the second side wall plate 122, the third side wall plate 123, Or you may connect with the 4th side wall board 124 with a hinge. That is, the bottom plate 11 only needs to be connected to any one of the four side wall plates 121 to 124 by a hinge.

  In addition, the cover plate 14 is connected to the first side wall plate 121 by the hinge. However, if the cover plate 14 can be fixed to the cylindrical body 12, the second side wall plate 122, the third side plate The side wall plate 123 or the fourth side wall plate 124 may be connected by a hinge. That is, the lid plate 14 may be connected to any one of the four side wall plates 121 to 124 by the hinge.

  In addition, a hook-and-loop fastener is used to fix the cover plate 14 and the bottom plate 11 to the cylinder 12. However, if the cover plate 14 and the bottom plate 11 can be fixed to the cylinder 12, other than buttons, magnets, etc. The locking member may be used.

  In addition, the direction in which the plane of the sheet 20 faces is the same as the direction in which the planes of the first side wall plate 121 and the second side wall plate 122 face, but the sheet 20 supports the packaging object. If possible, the direction of the planes of the third side wall plate 123 and the fourth side wall plate 124 may be the same, and the direction of the planes of the four side wall plates 121 to 124 may be the same. It does not have to be the same. Furthermore, although the number of sheets 20 is four, an arbitrary number such as three or five may be selected according to the thickness of the substrate to be accommodated.

(Second Embodiment)
In the first embodiment, the main body 10 includes the bottom plate 11, the cylindrical body 12, the first fixing member 13, the lid plate 14, and the second fixing member 15. In order to improve, other components may be further provided. Hereinafter, as an example, an example in which a reinforcing plate is further provided as a component of the main body 10 in order to increase the bending strength of the cylindrical body 12 of the main body 10 will be described. In addition, the same code | symbol is attached | subjected to FIG. 1-FIG. 6 and an identical part.

  The packaging box 100 according to the embodiment of the present invention shown in FIG. 7 includes a reinforcing plate 16 at the end of the third side wall plate 123 facing the lid plate 14. In addition, the packaging box 100 includes a reinforcing plate 16 at the end of the fourth side wall plate 124 that faces the lid plate 14. And the 3rd side wall board 123 and the 4th side wall board 124, and the reinforcement board 16 are connected with the hinge.

  Further, as shown in FIG. 8, the packaging box 100 includes a reinforcing plate 17 at the end of the third side wall plate 123 that faces the bottom plate 11. Further, the packaging box 100 includes a reinforcing plate 17 at an end portion of the fourth side wall plate 124 facing the bottom plate 11. And the 3rd side wall board 123 and the 4th side wall board 124, and the reinforcement board 17 are connected with the hinge.

  Thereby, compared with the case where the main body 10 does not include the reinforcing plates 16 and 17, the plane sectional modulus of the third side wall plate 123 and the fourth side wall plate 124 is increased, and the bending strength of the cylindrical body 12 is increased. Can be increased.

  In addition, this invention is not limited to said embodiment, A various deformation | transformation and application are possible. For example, although the example which folds the sheet | seat 20 was shown, the number of folding is arbitrary and it should just be partly folded. In addition, although an example in which a weak adhesive is stacked and bonded is used as a temporary fixing and substantially one sheet is shown, bonding may not be performed. Moreover, although the example which folds the sheet | seat 20 was shown, the sheet | seat 20 does not need to be folded. In this case, as shown in FIG. 3A, the sheet 20 has a size W larger than the size L in the front horizontal direction of the packaging box 1, and thus one end thereof is fixed to the inner wall of the third side wall plate 123. In a state where the other end is fixed to the inner wall of the fourth side wall plate 124, it becomes a bumpy state. Moreover, although the size of the accommodation was made into two steps, it may be larger. In this case, for example, the degree of adhesion of a portion overlapping with the number of folds may be adjusted so that the substantial length of the sheet 20 can be changed in multiple stages.

  Further, although the reinforcing plate 16 and the reinforcing plate 17 are members that increase the bending strength, they may be used as a fixing member that fixes the bottom plate 11 and the cover plate 14 to the cylindrical body 12. Specifically, as shown in FIG. 9, the notch portions 151 are provided at both ends of the second fixing member 15, and the cover plate 14 is folded on the reinforcement plate 16 in a state where the reinforcement plate 16 is folded inside the main body 10. The lid plate 14 may be fixed to the cylindrical body 12 by inserting the reinforcing plate 16 into the notch 151. Thereby, a hook-and-loop fastener does not need to be used.

  Similarly, notch portions 131 are provided at both ends of the first fixing member 13, the bottom plate 11 is folded on the reinforcing plate 17 in a state where the reinforcing plate 17 is folded inside the main body 10, and the reinforcing plate 17 is attached to the notch portion 151. The bottom plate 11 may be fixed to the cylindrical body 12 by being inserted. Thereby, a hook-and-loop fastener does not need to be used.

  Further, the reinforcing plate 16 and the reinforcing plate 17 shown in FIG. 7 and FIG. 8 are connected to the end portions of the third side wall plate 123 and the fourth side wall plate 124. You may connect with the edge part of the 2 side wall board 122. FIG. In this case, the reinforcing plate 16 and the reinforcing plate 17 are connected to the end portion of the first side wall plate 121 facing the cover plate 14 and the end portion facing the bottom plate 11 by hinges, respectively. The reinforcing plate 16 and the reinforcing plate 17 are connected to the end of the second side wall plate 122 facing the cover plate 14 and the end facing the bottom plate 11 by a hinge.
