  In the conventional storage box, when the target object is stored, the projecting piece supporting the target object may return into the notch of the inner plate, which is troublesome when the target object is stored in the storage box. In addition, since the projecting piece is bent inward so that the lower end edge is mountain-folded, the projecting piece easily returns to the inner plate side by its own restoring force. The projecting piece that has once returned to the inner plate is difficult to return inward again, and in order to ensure that the projecting part comes into contact with the collar part from below, the tip of the projecting piece is positioned below the collar part. It is necessary to support with a finger and is troublesome.

  An object of this invention is to provide the storage box which raised the storage efficiency in view of the above point.

In order to achieve the above-mentioned object, the present invention is a storage box that is assembled by folding upward a side plate that is connected to a side edge of a rectangular bottom plate, and that accommodates an object having a collar portion, and faces each other. Inner plates are respectively provided on the upper edges of the side plates so as to be folded inward to form a double structure, and the inner plates are formed so as to be connected to the inner plates at the upper ends by incisions. By folding back upward, a support portion whose tip is in contact with the flange portion from below is provided, and the support portion does not contact the inner surface of the box formed by the side plate and the inner plate at both lateral edges. And is capable of swinging in a direction away from the inner plate by its own restoring force.

According to the present invention, the support portion connected to the inner plate at the lower end edge is folded back in a V shape so as to overlap the inner surface of the inner plate upward from the inner plate so as to valley-fold the lower end edge. . As a result, the support portion moves in the direction away from the inner plate (the direction of the bottom plate) by its own restoring force, with the lateral side edges of the support portion not contacting the inner surface of the box formed by the side plate and the inner plate. try to. Therefore, the support portion folded back so as to overlap the inner plate does not return into the inner plate, can be appropriately brought into contact with the collar portion of the object from below, and the accommodation efficiency can be improved.

  Here, the support portion may be formed by providing a U-shaped notch so as to form a support portion connected to the inner plate at the upper end. However, in this case, it is difficult to pick the support portion, and it is difficult to pull the support portion from the inner plate and fold it upward. Although it is considered to form a hole part into which a finger can be inserted in correspondence with the U-shaped notch, the part punched for the formation of the hole part becomes garbage, and there is a problem that waste in the manufacturing process of the storage box increases. There is.

  In this case, the front end edge of the support portion may be set so as to be flush with the lower end edge of the inner plate before being folded back from the inner plate. According to this configuration, the tip of the support portion can be picked and folded without being obstructed by the inner plate, and an increase in dust in the manufacturing process can be prevented.

  Further, when the storage box of the present invention is configured so that a plurality of objects can be stored along the side plate and the inner plate, as the support portion, a plurality of support portions are formed on the inner plate corresponding to each object. It is also possible to do. However, as the number of objects to be accommodated increases, the number of support portions increases, and the work of folding back the support portions also becomes troublesome.

  In this case, the support portion is configured so that the tip is brought into contact with the collar portion from the lower side across a plurality of objects, and the inner plate is notched upward from the valley fold line continuously provided with the support portion. A U-shaped notch is provided so that the inner projecting piece formed by being cut out is connected to the support part at the lower end, and when the support part is folded, it is formed by the U-shaped notch, What is necessary is just to comprise so that the front-end | tip of the protrusion piece provided in a row with the lower end of the folded support part can contact | abut to a bottom plate.

  According to such a configuration, since one support portion supports a plurality of objects, the number of times the support portions are folded back with respect to the number of objects to be stored is reduced, and the assembly work of the storage box is facilitated. Further, when a plurality of objects are supported by one support part, the load of the object applied to one support part increases. However, in this invention, a support part can support a several target object firmly, when the lower end of the protrusion piece provided in a row by the lower end of a support part contact | abuts to a baseplate.

  Further, in the present invention, when a partition plate arranged parallel to the inner plate is provided on the bottom plate, the partition plate is positioned so as to face the support portion of the inner plate, and is folded upward on the inner side. The support part with which the front-end | tip contacts can be provided in a collar part from the downward direction.

FIG. 3 shows a development view of the storage box 1 of the present embodiment. On both side edges of the short side plate 3, tongue pieces 3a are provided so as to have a length equal to or less than half the width of the long side plate 4. A shoulder portion 5 that extends slightly larger than the thickness of the cardboard is connected to the upper edge of the longitudinal side plate 4.

  An inner plate 6 is connected to the upper edge of the shoulder 5. At the distal end of the inner plate 6, there are provided J-shaped cut portions 7 that are located at both end portions and are notched in a J-shape that gradually curves inward in the width direction from the distal end toward the proximal end. Yes. A fold line 8 extending so as to connect the base ends of both J-shaped cut portions 7 is provided at the base end of the J-shaped cut portions 7. A portion defined by the two J-shaped cut portions 7 and the folding line 8 is the support portion 9 of the present embodiment.

  Further, the inner plate 6 is provided with a U-shaped cut portion 10 which is cut so as to draw a semicircle from the folding line 8 toward the shoulder portion 5 side of the inner plate 6. The projecting piece 11 is defined by the U-shaped cut portion 10. The projecting piece 11 is connected to the support portion 9 without going through the folding line 8. As a result, when the support portion 9 is folded back so as to overlap the inner surface of the inner plate 6 along the folding line 8, the projecting piece 11 rotates so as to approach the place where the support portion 9 was before being folded back.

  Further, engaging pieces 12 projecting downward are continuously provided at both ends of the lower edge of the inner plate 6. The engagement piece 12 is inserted into an engagement hole 13 provided at a corresponding position of the bottom plate 2, and the inner plate 6 is fixed.

  To assemble the storage box 1, first, the short side plate 3 is erected vertically through the crease line L <b> 1. Then, the tongue piece 3a is bent inward so as to be perpendicular to the short side plate 3 via the crease line L2.

Next, as shown in FIG. 4 , the longitudinal side plate 4 is erected vertically through the crease line L <b> 3 so as to be along the side surface of the tongue piece 3 a. Then, the shoulder 5 is bent inward at a right angle through the crease line L4. Then, the inner plate 6 is bent downward at a right angle through the crease line L5 so that the tongue piece 3a is sandwiched between the inner plate 6 and the long side plate 4. At this time, the engagement piece 12 is inserted into the engagement hole 13 and the inner plate 6 is fixed. In addition, the side plate of the storage box 1 has a double structure with the long side plate 4 and the inner plate 6.

  Further, at the same time as bending the inner plate 6 at a right angle, the support portion 9 is folded back through the folding line 8 so as to be valley-folded upward. A space between the object A and the bottom plate 2 is formed by bringing the flange Aa of the object A such as a tray having a flange into contact with the tip of the support 9.

  Further, a projecting piece 11 is connected to the lower end of the support portion 9. When the object A is supported by the support portion 9, the lower end of the projecting piece 11 comes into contact with the bottom plate 2. Thereby, the target A can be firmly supported by the support portion 9.

  As shown in FIG. 1, the storage box 1 of the present embodiment is provided with a partition plate 14 that rises in parallel with the long side plate 4 and the inner plate 6. The partition plate 14 is configured separately from the main body of the storage box 1. The partition plate 14 includes a pair of partition plate main bodies 15 disposed so as to face the inner plate 6, and a connecting plate 16 that connects the upper ends of both partition plate main bodies 15.

In the same manner as the inner plate 6, both partition plate bodies 15 are provided with a J-shaped cut portion 17, a folding line 18, a support portion 19, a U-shaped cut portion 20, and a protruding piece 21. FIG. 5 shows a development view of the partition plate 14.

Here, with reference to FIG. 6, the assembly method of the partition plate 14 is demonstrated . First, the partition plate body 15 is bent downward through the crease line L6 so as to be perpendicular to the connecting plate 16. Then, the support portion 19 is folded back along the outer surface of the partition plate body 15 with respect to the partition plate body 15 via the folding line 18. A flange portion Aa of the object A such as a tray having the flange portion Aa is brought into contact with the tip of the support portion 19 to form a space between the object A and the bottom plate 2.

  Further, a projecting piece 21 is connected to the lower end of the support portion 19, and when the object A is supported by the support portion 19, the lower end of the projecting piece 21 comes into contact with the bottom plate 2. As a result, the object A can be firmly supported by the support portion 19.

  In addition, insertion pieces 15 a protrude from both ends of each partition plate body 15. Further, the short side plate 3 is provided with insertion holes 3b corresponding to the insertion pieces 15a. The partition plate 14 is fixed to the main body of the storage box 1 by inserting the insertion piece 15a into the insertion hole 3b.

  According to the storage box 1 of the present embodiment, the support portion 9 connected to the inner plate 6 at the lower end edge is formed on the inner surface of the inner plate 6 upward from the inner plate 6 so as to bend the lower end edge. It is folded in a V shape so as to overlap. As a result, the support portion 9 can swing about the folding line 8 and tends to move away from the inner plate 6 (the direction of the bottom plate 2) by its own restoring force.

  Accordingly, the support portion 9 that is folded back so as to overlap the inner plate 6 does not return to the inner plate 6 by its own restoring force alone, and is appropriately brought into contact with the flange Aa of the object A from below. Can do. And since the support part 9 can prevent returning in the inner board 6 unintentionally, the efficiency which accommodates the target object A of the storage box 1 can be improved.

  Further, the support portions 9 and 19 come into contact with the side wall of the object A in an attempt to move away from the inner plate 6 or the partition plate main body 15 by their restoring force. For this reason, even if the object A swells somewhat by stuffing contents such as strawberries and grapes, it is possible to appropriately adjust the tip positions of the support portions 9 and 19, and to properly adjust the tips of the support portions 9 and 19. Can be brought into contact with the flange Aa.

  Further, the support portion 19 of the partition plate 14 is also connected to the partition plate main body 15 at the lower end edge, and the lower end edge of the support portion 19 is valley-folded so that the partition plate main body 15 is upwardly moved upward. It is folded back in a V shape so as to overlap the outer surface (the surface facing the inner plate 6). As a result, the support portion 19 can swing around the folding line 18 and tends to move away from the partition plate main body 15 (in the direction of the bottom plate 2) by its own restoring force. Therefore, the support portion 19 that is folded back so as to overlap the inner plate 6 does not return to the inside of the partition plate main body 15 only by its own restoring force, but is appropriately brought into contact with the flange portion Aa of the object A from below. be able to.

  Here, it is also conceivable that the support portion is formed by providing a U-shaped notch so as to constitute a support portion connected to the inner plate 6 at the upper end. However, in this case, it is difficult to pick the support portion from the inner plate 6, and it is difficult to pull the support portion from the inner plate 6 and return it upward. Although it is considered to form a hole part into which a finger can be inserted corresponding to the U-shaped notch, the part punched for the formation of the hole part becomes new garbage, and waste in the manufacturing process of the storage box increases. There is a problem.

  Therefore, in the storage box 1 of the present embodiment, the front end edges of the support portions 9 and 19 are flush with the lower end edge of the inner plate 6 or the partition plate body 15 before being folded back from the inner plate 6 or the partition plate body 15. It is set to become. With this configuration, the tips of the support portions 9 and 19 can be gripped and folded without being obstructed by the inner plate 6 or the partition plate body 15, and an increase in dust in the manufacturing process can be prevented. .

  Moreover, in the storage box 1 of this embodiment, the support parts 9 and 19 are comprised as what makes a front-end | tip contact | abut on the collar part Aa ranging over the some target object A from the downward direction. The inner plate 6 or the partition plate main body 15 is notched upward from the folding lines 8 and 18 as valley fold lines provided continuously with the support portions 9 and 19, and is formed by being cut out. U-shaped notch portions 10 and 20 are provided so that the protruding pieces 11 and 21 are connected to the support portions 9 and 19 at the lower end.

  When the support portions 9 and 19 are folded back with respect to the inner plate 6 or the partition plate body 15, the support portions 9 and 19 are formed by the U-shaped cut portions 10 and 20, and are connected to the lower ends of the folded support portions 9 and 19. The tips of the projecting pieces 11, 21 come into contact with the bottom plate 2.

  By comprising in this way, since the one support parts 9 and 19 support the some target object A, with respect to the number of the target objects A accommodated, in other words, the support part. The number of turns 9 and 19 can be reduced, and the assembling work of the storage box 1 becomes easy. Moreover, if the several support object A and 19 are supported by the one support part 9 and 19, the load of the target object A added to the one support part 9 and 19 will increase. However, in the storage box 1 of the present embodiment, the lower ends of the projecting pieces 11 and 21 connected to the lower ends of the support portions 9 and 19 come into contact with the bottom plate 2, so that the support portions 9 and 19 are firmly attached to a plurality of objects. The object A can be supported.

  In addition, in this embodiment, the storage box 1 which accommodates four trays, such as a strawberry pack, was demonstrated. However, the storage box of the present invention is not limited to this, and there may be one target object such as a tray or two or more.

Moreover, in this embodiment, the storage box 1 partitioned into two rows by the one partition plate 14 was demonstrated . However, the storage box of the present invention is not limited to this, and may be a single-line storage box without a partition plate, or may be a three-row or more storage box including a plurality of partition plates.
