Description

Technical Field

[0001] The utility model relates to the field of packaging, in particular to a honeycomb paperboard packaging box with light weight and high strength. Background Art

[0002] As a container for protecting and storing items, packaging boxes are usually made of cardboard, wood, plastic or other materials. They are mainly used to protect items from damage, facilitate the handling and storage of items, and provide product information and brand display. They can be customized into different sizes and shapes to accommodate a variety of different types of items.

[0003] As the most common type of packaging box, cardboard packaging boxes are mostly made of corrugated cardboard / hardboard, glue and tape. They are lightweight, foldable and recyclable, and can be used to package various small and medium-sized items. However, traditional cardboard packaging boxes also have the disadvantage of poor load-bearing capacity, making it difficult to package some large and heavy items, and the packaging boxes are easily deformed during transportation and storage, affecting the appearance.

[0004] Honeycomb paperboard is a new type of packaging material with a paper honeycomb sandwich structure as its core. It can be used to improve the load-bearing defects of traditional paperboard packaging boxes and is mostly used to place some medium and large-sized items as packaged objects. However, honeycomb paperboard in the prior art is mostly formed by directly bonding its edges with adhesives or with F-type connectors in combination with adhesives. The outer side of the bonding surface is prone to collapse after being subjected to force. At the same time, honeycomb paper has strength defects on the side, so it is very inconvenient to place large items. It is easy to damage the corners and cause the honeycomb paperboard to collapse. In addition, the packaging box needs to be broken when taking out, which is also very inconvenient. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a honeycomb paperboard packaging box to solve the technical defects in the above background.

[0009] As a further limitation, the side panels, top panels and side cover panels are sealed with U-shaped edging strips at the outer edges of the honeycomb paperboard serving as the base plate; corner guards are formed at the corners of the box body; the edging and corner guards are both made of hot-pressed paperboard or calcium plastic material.

[0010] As a further limitation, the reinforcing clip strip is formed with a guide structure with an oblique angle on the outer side of the annular section; correspondingly, the side cover plate is provided with an oblique section matching the guide structure to facilitate covering.

[0011] As a further limitation, the inner side of the base plates of the side plates, top plate and side cover plates of the box body is formed with lining plates, and the lining plates are formed by overlapping and bonding multiple layers of honeycomb cardboards, and by overlapping honeycomb cardboards of different sizes, the lining plates have a fitting surface that matches the corresponding side of the item to be packaged.

[0012] As a further definition, the guide wheel includes a wheel body, and both sides of the wheel body have wheel seats that match the size of the openings on the lining plate. The wheel seat has an outward expansion panel on the outer side of the top surface, and a glue layer is molded on the lower surface of the outward expansion panel.

[0019] See also Figure 1 A schematic diagram of a preferred embodiment of a honeycomb paperboard packaging box is shown. In this embodiment, the main body of the honeycomb paperboard packaging box is a box body, which includes independently formed left side panels, right side panels, rear side panels, top panels and bottom panels.

[0020] The left side panel, right side panel, rear side panel and top panel of the box body are similar in structure, and the difference lies only in structure and size; the aforementioned left side panel, right side panel, rear side panel and top panel all include a substrate and a lining panel formed on the surface of the substrate, namely, the corresponding left side panel substrate (viewing side, not marked), left side panel lining panel (viewing side, not marked), right side panel substrate 4, right side panel lining panel 3, rear side panel substrate 14, rear side panel lining panel 13, top panel substrate 1 and top panel lining panel 2 respectively; the aforementioned left side panel substrate, right side panel substrate 4, rear side panel substrate 14 and top panel substrate 1 are honeycomb paperboards cut and formed according to size and then spliced, and after splicing, they are bonded into the structural body of a rectangular box body, while the left side panel lining panel, right side panel lining panel 3, rear side panel lining panel 13 and top panel lining panel 2 are multi-layer honeycomb paperboards cut and overlapped, and after overlapping, they are bonded and formed on the corresponding substrate surface, and the function of the lining panel is to form a buffer structure against the surface of the object to limit the position of the packaged object in the box space.

[0021] In the present embodiment, the bottom plate constituting the box body is a combined plate body, which includes a bottom plate substrate 9 and a bottom plate panel 10, wherein the bottom plate substrate 9 is a high-density plastic plate integrally formed in one piece, and the surface of the bottom plate substrate 9 is formed with the bottom plate panel 10 in a surface bonding manner, and the bottom plate panel 10 is formed by cutting and forming honeycomb paperboard, and the bottom plate panel 10 is formed with four square holes, and guide wheels are embedded and fixed in the holes; the structural style of the guide wheel is shown in the figure, which includes a wheel seat 11 matching the hole size, and the wheel seat 11 is used to be embedded in the hole, and a wheel body 12 higher than the upper surface of the wheel seat 11 is arranged in the middle position of the wheel seat 11, and in addition, an outward expansion panel 8 is provided on the outer side of the top surface of the wheel seat 11, and a glue layer is formed on the lower surface of these outward expansion panels 8, and when the guide wheel is assembled in the above-mentioned hole as a whole through the wheel seat 11, it is adhered to the surface of the bottom plate panel 10 through the glue layer on the lower surface of the outward expansion panel 8.
