Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging box, and more particularly to a packaging box provided with a support piece capable of directly supporting a stored product or a partition body fitted in the box.

[0002]

[Prior art and problems of the invention]

 As a corrugated cardboard packaging box for product packaging, as shown in FIG. 8, a body 52 is formed on the periphery of a bottom wall 51, and a lid wall 53 is provided on the body 52. Is.

In such a packaging box, as shown in FIG. 9, since the bottom wall 51 receives the entire load of the stored goods, the bottom wall 51 is easily bent, and the bottom wall 51 has such strength as to withstand the load. Is required. However, if part of the load of the stored products can be received by the body portion 52, the burden on the bottom wall 51 is reduced, and the thickness of the corrugated board used can be reduced. Be advantageous

Further, in the above packaging box, as shown in FIG. 10, the partition body 60 may be fitted in the body portion 52 to store the product in two upper and lower stages.

The partition body 60 in this case is generally one in which a support plate 62 along the body 52 of the packaging box is continuously provided on the periphery of the partition plate 61 as shown in the figure. When the support plates 62 are provided on the entire circumference, it is necessary to fit the support plates 62, which are spread out in all directions, into the packaging box while pressing the support plates 62 inward, which is extremely inferior in workability.

Therefore, if the support plate 62 is provided only on the opposite edges of the partition plate 61 in consideration of the ease of fitting, the center portion of the partition plate 61 between both support plates 62 will bend downward. As shown in Fig. 11, if the lower end of the support plate 62 gets inside due to some reason, the end of the partition plate 61 may go down and the lower products may be damaged by the load. is there.

Even when the partition body 60 is used in this manner, if a part of the partition plate 61 can be supported by the body portion, as in the above case, the support plate 62 is small and the partition body that is easy to fit can be held in a stable state. it can.

Therefore, an object of the present invention is to improve a packaging box of this type so that a part of a stored product itself or a partition body can be supported by a body portion.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a pair of opposing side walls 12 and a pair of opposing lower end walls 14b on a peripheral edge of a bottom wall 11 so that both side edges and an upper edge of the side wall 12 are provided. The folding piece 13 and the lid wall 17 are continuously provided to the upper end edge of the lower end wall 14b at the upper end edge of the lower end wall 14b by being folded in two at the inner end of the lower end wall 14b. The lower end edge of the projecting support piece 16 is continuously provided via a fold line 25, the upper end wall 14a is provided continuously to the upper end edge of this support piece 16 via a fold line 27, and the upper end of this upper end wall 14a is provided. An inner end wall 15 to be overlapped with the folding piece 13 is continuously provided at an edge via a fold line 28, and the folding piece 13 is provided with a notch 13a into which a supporting piece 16 is inserted, and the supporting piece 16 is folded. Form the slit 16a along the line of sight 27 and engage with this slit 16a Is a projecting piece 15a was provided a cardboard packaging Sobako cardboard or the like provided in said end wall 15.

[0010]

[Action]

 In the packaging box configured as described above, the stored pieces and a part of the partition body are placed on and supported by the support piece 16 projecting inward.

[0011]

【Example】

 Hereinafter, embodiments will be described with reference to the drawings. As shown in FIG. 1, this packaging box 10 is a hot plate packaging box formed of cardboard or other cardboard, and is assembled from the blank shown in FIG. As shown in the figure, a pair of side walls 12 facing each other and a pair of end walls 14 facing each other through the fold lines 21 and 22 are continuously provided on the peripheral edge of the bottom wall 11. A folding piece 13 and a lid wall 17 are continuously provided on both side edges and an upper edge of the sheet via fold lines 23 and 24, respectively.

The end wall 14 is composed of an upper end wall 14 a and a lower end wall 14 b connected by a support piece 16, and the upper end wall of the upper end wall 14 a has a fold line 28 at the upper end edge thereof. An inner end wall 15 having the same shape as 14a is continuously provided.

The support piece 16 is folded in two along a fold line 26 and protrudes into the packaging box 10. The upper end edge and the lower end edge of the support piece 16 are folded along the fold lines 27 and 25 to the upper end wall 14 a. Of the lower end wall 14b and the upper end edge of the lower end wall 14b.

A slit 16 a is formed on the support piece 16 along the fold lines 25 and 27, and a projection piece 15 a that engages with the slit 16 a is continuously provided at the tip of the inner end wall 15. ing. Further, the folding piece 13 is formed with a notch 13a into which the folded piece 16 is inserted.

As shown in FIG. 2, in the packaging box 10 configured as described above, the folding piece 13 is bent while the side walls 12 are erected, and the supporting piece 16 is folded in two along a crease line 26. Then, when the supporting piece 16 folded in two is inserted into the cut 13b of the folding piece 13, the slit 16a is exposed along the inner surface of the folding piece 13 as shown in FIG. When the projection piece 15a is folded over 13 and the projecting piece 15a is engaged with the slit 16a, the folding piece 13 is sandwiched between the upper end wall 14a and the inner end wall 15 and the standing state of the side wall 12 and the end wall 14 is maintained. Then, the assembly of the packaging box 10 is completed.

When the hot plate A is stored in the packaging box configured as described above, as shown in FIG. 5, the foot a of the hot plate A is placed on the bottom wall 11 and the handle b is supported by the support piece 16. Since it is supported, the total load of the hot plate A is not applied to the bottom wall 11, and the bottom wall 11 is less likely to bend.

6 and 7 show a case in which a partition 40 is fitted in a packaging box 30 having the same structure as that of the above-described embodiment so that products can be stored vertically in two stages.

The partition body 40 includes a partition plate 41 having substantially the same shape as that of the bottom wall 31 of the packaging box 30, and a support plate 42 facing each other on both side edges of the partition plate 41 via fold lines 43. The support plate 42 is formed to have a length reaching the bottom wall 31 with both ends of the partition plate 41 placed on the support pieces 36. At the center of the partition plate 41, a hole 41a for pulling up the partition body 40 fitted in the packaging box 30 is provided.

Therefore, when the partition body 40 is fitted into the packaging box 30, both ends of the partition plate 41 are supported by the support pieces 36 and both side edges are supported by the support plates 42, so that the partition plate 41 moves downward. I'm not depressed.

[0020]

【effect】

 With the above-described structure, the packaging box 10 of the present invention can support the stored products, the partition body, and the like by the support piece 16 protruding from the body portion to the inside.

Therefore, for example, in the case of supporting the stored product itself, the total load of the stored product is not applied to the bottom wall 11, and the thickness of the corrugated cardboard used can be reduced. In terms of advantages.

Further, in the case of supporting the partition body, it is possible to reduce the number of support plates that are connected to the partition body, which makes it easier to fit the partition body in the packaging box and stabilizes the partition body in the packaging box. Can be held in the open state.
