Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging, and in particular to a folding cardboard packaging box. Background Technology
[0002] Current packaging for individually fragile items typically uses cardboard boxes as the outer packaging, with cushioning materials such as foam board or bubble wrap filling the inside and outside of the box to secure the fragile item. However, this packaging structure requires two or more materials, and the cardboard boxes also take up considerable space when stored. Utility Model Content
[0003] To address the aforementioned issues, this utility model proposes a folding cardboard packaging box. This packaging structure requires only cardboard to package fragile items, and it offers greater stability compared to other folding cardboard box packaging.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A folding cardboard packaging box, the main body of which is a long strip of cardboard body, half of which is an outer peripheral cardboard segment and the other half is a fixed cardboard segment. The fixed cardboard segment includes an eighth cardboard, a fifth cardboard, a sixth cardboard and a seventh cardboard starting from the outer peripheral cardboard segment. The eighth cardboard, the sixth cardboard and the seventh cardboard all have cutouts for fixing the packaged item.
[0006] When the cardboard body is folded, the fifth, sixth and seventh cardboard pieces form a triangular structure, and the outer peripheral cardboard segments can be enclosed to form a cylindrical structure and cover the outer ring of the fixed cardboard segments.
[0007] Preferably, the cardboard body has fold lines so that the cardboard body can be bent along the fold lines.
[0008] Preferably, the outer peripheral cardboard segment has multiple fold lines that run along the width direction of the cardboard body.
[0009] Preferably, the fold lines of the outer peripheral cardboard segment form a plurality of outer peripheral cardboard wall units on the outer peripheral cardboard, wherein the odd-numbered outer peripheral cardboard wall units have the same length, and the even-numbered outer peripheral cardboard wall units have the same length.
[0010] Preferably, the outer peripheral cardboard segment partially overlaps the cardboard body when folded, the cardboard body has a hollowed-out insertion slot at the starting position of the overlap, and the first end of the cardboard body has an insertion lug.
[0011] When the cardboard body is folded, the insertion port is inserted into the insertion ear to fix the outer peripheral cardboard segment in the enclosed state.
[0012] Preferably, the insert has a fold line at the first end of the cardboard body.
[0013] The beneficial effects of using this utility model are:
[0014] This folding cardboard packaging box forms a cylindrical structure by gradually bending and enclosing the outer cardboard ends, achieving the effect of external packaging. In terms of stability, this folding cardboard packaging box uses the eighth cardboard as a base and opens a third fixed cutout in the eighth cardboard, which limits the position of the packaged item and its bottom, thus making the packaged item more securely positioned and less likely to fall out or break. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the unfolded folding cardboard packaging box of this utility model.
[0016] Figure 2 This is a partial rendering of the folding cardboard packaging box of this utility model after packaging.
[0017] The reference numerals in the figures include:
[0018] 10-Outer perimeter cardboard segment, 11-First cardboard, 111-Ear, 12-Second cardboard, 13-Third cardboard, 14-Fourth cardboard;
[0019] 20 - Fixed cardboard segment, 21 - Fifth cardboard, 22 - Sixth cardboard, 221 - First fixed cutout, 23 - Seventh cardboard, 231 - Second fixed cutout, 24 - Eighth cardboard, 241 - Slot, 242 - Third fixed cutout. Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.
[0021] like Figure 1 As shown, this embodiment proposes a folding cardboard packaging box, the main body of which is a long strip of cardboard. Half of the cardboard main body is an outer peripheral cardboard segment 10, and the other half is a fixed cardboard segment 20. The outer peripheral cardboard segment 10 also has three creases arranged along the width direction of the cardboard main body. These three creases divide the outer peripheral cardboard segment 10 into a first cardboard 11, a second cardboard 12, a third cardboard 13, and a fourth cardboard 14. A solid and protruding insert 111 is formed on the side of the first cardboard 11 away from the second cardboard 12.
[0022] Three creases are also set along the width of the cardboard body on the fixed cardboard segment 20. These three creases divide the fixed cardboard segment 20 into the eighth cardboard segment 24, the fifth cardboard segment 21, the sixth cardboard segment 22, and the seventh cardboard segment 23 in sequence, with the eighth cardboard segment 24 being closer to the outer peripheral cardboard segment 10. A first fixed cutout 221 is made on the sixth cardboard segment 22, a second fixed cutout 231 is made on the seventh cardboard segment 23, and a third fixed cutout 242 is made on the eighth cardboard segment 24. A cutout slot 241 is made on the crease of the eighth cardboard segment 24 near the fourth cardboard segment 14.
[0023] In this embodiment, since the folded cardboard packaging box is used to package the water cup, an irregular first fixing cutout 221 is opened at the first fixing cutout 221, and the water cup body and the water cup handle are correspondingly arranged in the first fixing cutout 221.
[0024] like Figure 2 As shown, when folding and using the cardboard box, the fifth cardboard 21, the sixth cardboard 22, and the seventh cardboard 23 are first folded into triangles. The fifth cardboard 21 is set vertically, and the eighth cardboard 24 is laid flat at the bottom. The third fixing cutout 242 on the eighth cardboard 24, the second fixing cutout 231 on the seventh cardboard 23, and the first fixing cutout 221 on the sixth cardboard 22 are vertically opposite each other. Then, a water cup is placed into the third fixing cutout 242, the second fixing cutout 231, and the first fixing cutout 221. Then, the fourth cardboard 14, the third cardboard 13, the second cardboard 12, and the first cardboard 11 are surrounded by the outer ring of the fixed cardboard section 20. At this time, the first cardboard 11 and the eighth cardboard 24 are attached. Then, the insert 111 is inserted into the slot 241 to complete the assembly of the cardboard box.
[0025] Preferably, the fold lines of the outer peripheral cardboard segment 10 form a plurality of peripheral cardboard wall units on the outer peripheral cardboard segment 10, wherein the odd-numbered peripheral cardboard wall units have the same length, and the even-numbered peripheral cardboard wall units have the same length. The last fixed cardboard wall unit on the fixed cardboard segment 20, adjacent to the second end of the cardboard body, has the same length as either the odd-numbered or even-numbered peripheral cardboard wall units. Such a folded cardboard packaging box can be formed into a rectangular packaging box.
[0026] This folding cardboard packaging box forms a cylindrical structure by gradually bending and enclosing the outer cardboard ends, achieving the effect of external packaging. In terms of stability, this folding cardboard packaging box uses the eighth cardboard 24 as a base and opens a third fixed cutout 242 on the eighth cardboard 24 to limit the position of the main body and bottom of the packaged item, thus making the positioning of the packaged item more stable and less likely to fall out or break.
[0027] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
