[0002] For octagonal packaging boxes, the existing technology mostly adopts a top and bottom cover structure formed by gray board. However, this structure has certain limitations, especially for gift boxes that need to hold milk bags or other block-shaped items. The carrying space it provides is too large, which is not conducive to the positioning of the placed items. In addition, there is an octagonal packaging box in the existing technology, which is composed of an inner box and an outer box, wherein the material of the inner box and the outer box are both gray boards with facial tissue on the surface. The inner box is designed in the form of a partition, and the positioning is achieved by squeezing together several inner boxes in the outer box. Although this design has a certain limiting effect on the items, its material cost is relatively high. Therefore, it is necessary to develop a new solution that can not only solve the problem of lack of item positioning in the existing technology, but also reduce material and production costs.

DETAILED DESCRIPTION

[0024] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] An octagonal inner support packaging box, such as Figure 1-3As shown, the inner box 1 comprises an inner tray 2 and an outer box 3. The inner box 1 is formed by folding a first sheet 11 and comprises an upper octagonal bottom plate 12, an inner folding portion 13, a lower octagonal bottom plate 14, and side panels. A receiving groove 121 is defined in the center of the upper octagonal bottom plate 12. The inner folding portion 13 extends from the upper octagonal bottom plate 12 into the receiving groove 121. The inner folding portion 13 folds down along the fold line between the upper octagonal bottom plate 12 and the upper octagonal bottom plate 12 to form the receiving groove 121 in the center of the upper octagonal bottom plate 12. The lower octagonal bottom plate 14 is located below the upper octagonal bottom plate 12. The side panels are used to form the side surfaces of the upper octagonal bottom plate 12 and the lower octagonal bottom plate 14. The inner tray 2 is shaped to match the receiving groove 121 and can be engaged in the receiving groove 121 and contact the inner folding portion 13. The outer box 3 is connected to the inner box 1 and covers at least the upper and lower surfaces of the inner box 1. The side panels can be formed by extending the upper and lower octagonal bottom panels, or they can be folded and wrapped around the side corners between the upper and lower octagonal bottom panels. The present invention only limits the inner box to being formed by folding, but the specific folding method can be selected by those skilled in the art from various conventional means.

[0027] The inner surface of the inner box 1 is reinforced with corrugated steel. This reinforced steel ensures the inner box's strength while saving material costs. Furthermore, it increases the thickness of the contact surface, making it more secure when squeezed, such as between the latch 153, the folding tongue and the side panels, the side panels, and the inner fold 13 and the inner support.

[0028] The inner support 2 has an opening at its top, and is formed by folding the second sheet 21. Folding can save costs.

[0029] like Figure 6 As shown, one of the folding methods is as follows: the second sheet 21 includes four inner support side panels 211 connected in sequence laterally, wherein the two inner support side panels 211 opposite to each other after folding have inner support bottom panels 212 extending to the same side. When the inner support 2 is formed, the inner support bottom panels 212 on both sides are folded inward to form the bottom surface of the inner support 2, and the side panels at the outermost edges of the four inner support side panels 211 are extended with connecting tongues 213.

[0030] The side panels include extended side panels 151, positive side panels 152 and latches 153. The shape of the lower octagonal bottom panel 14 matches that of the upper octagonal bottom panel 12. When the inner box 1 is in the first sheet 11 state, the latches 153 are formed by extending the extended side panels 151 to the upper and lower sides respectively. The upper octagonal bottom panel 12 or the lower octagonal bottom panel 14 includes alternating positive edges and side edges. The positive edges of the upper and lower sides of the upper octagonal bottom panel 12 and the lower octagonal bottom panel 14 extend outward to form the positive side panels 152, and the side edges of the upper octagonal bottom panel 12 and the lower octagonal bottom panel 14 extend outward to form gaskets 154; one of the extended side panels 151 is located between the upper octagonal bottom panel 12 and the lower octagonal bottom panel 14, and the other extended side panel is formed by extending the positive edge of the upper octagonal bottom panel 12 or the lower octagonal bottom panel 14 to the side.

[0031] like Figure 4 As shown, when the inner box 1 is formed, the front side panels 152 of the upper octagonal bottom panel 12 and the lower octagonal bottom panel 14 are folded inward and overlapped, wherein the inner front side panel 152 is provided with a notch 1521, and the outer front side panel 152 is extended with an inserting plate 1522, which is folded inward and inserted into the notch 1521 and locked therewith.

[0032] As another embodiment, the difference is that, Figure 5 As shown, when the inner box 1 is formed, the front side panels 152 of the upper octagonal bottom panel 12 and the lower octagonal bottom panel 14 are folded inward, and the front side panels 152 are provided with crease lines in the transverse direction. The front side panels 152 are folded along the crease lines so that the folded-in parts of the upper and lower front side panels 152 are elastically squeezed against each other; the folded-in parts of the front side panels 152 are approximately horizontal and abutted together, and the unfolded parts of the front side panels 152 form the sides of the inner box 1.

[0033] The latch 153 has side surfaces that partially form the upper octagonal bottom plate 12 and the lower octagonal bottom plate 14 . An inner folding tongue 1531 extends outward from the latch 153 . The inner folding tongue 1531 folds inward and is inserted between the gasket 154 and the front side plate 152 to form a lock.

[0034] The receiving groove 121 is rectangular, and a cutting line 131 is provided between adjacent inward folding portions 13 . The cutting line 131 separates the upper octagonal bottom plate 12 into trapezoidal or triangular inward folding portions 13 .

[0035] A handle 155 is provided on the extended side panel 151 or the front side panel 152 , and a slot 31 is correspondingly provided in the outer box 3 for exposing the handle 155 .

[0036] The outer box 3 is a top and bottom cover or an integrated type. If the outer box 3 is an integrated type, the outer box 3 has at least four cover plates 32 connected in sequence. The four cover plates 32 surround the inner box 1, corresponding to the upper octagonal bottom plate 12, the lower octagonal bottom plate 14 and the positive side plates 152 on both sides.

[0037] When in use, first fold the inner box 1, place the inner support on top of the receiving groove, and press the inner folding part 13 downwards to install the inner support into the receiving groove. At this time, the inner folding part 13 provides some support to the inner box 1 due to its own elastic restoring force, helping to better fix the inner box 1. Then, wrap the outer box over the inner box outer 1 to cover the inner support. If the outer box and the inner box are connected by gluing, etc., if the outer box 3 is an integrated type, the outer box and the inner box can be connected by gluing, adding an iron block and magnets to the opening, or gluing, etc. The methods are conventional operations of those skilled in the art and are not limited here.
