Description

Low-cost easy-to-assemble paper cushioning protector with high strength and impact resistance

The invention relates to the technical field of packaging, in particular to a low-cost, easy-to-assemble paper cushioning protector with high strength and impact resistance.

With the development of network technology, the growth of e-commerce is becoming more and more prosperous; e-commerce operators must properly pack the goods in packing boxes before handing over the goods to the freight forwarders. Bags, ... etc. (hereinafter collectively referred to as packaging boxes), and then cover the cover of the packaging box and then stick it with tape to seal it; other postal services are roughly the same. As shown in Figures 1 and 2, a general packing box structure has a main board A, and the same side of the main board A is sequentially bendable to form a first side board A1, a second side board A2, a third side board A3 and a fourth side board A4, the same other side is then sequentially bendable to form the fifth side panel A5, the sixth side panel A6, the seventh side panel A7 and the eighth side panel A8, and the first side panel A1 corresponds to the fifth side panel A5, and the second side panel A5 corresponds to the fifth side panel A5. The side panel A2 corresponds to the sixth side panel A6, the third side panel A3 corresponds to the seventh side panel A7, and the fourth side panel A4 corresponds to the eighth side panel A8, and one end of the main board A forms a protruding panel A9; by this structure , after bending according to the fold line (dotted line shown in Figure 1), a three-dimensional rectangular packing box can be formed, and then glue the protruding plate A9 to the other end of the main board A to fix the three-dimensional shape after coating the adhesive box.

In order to prevent the goods packed in the packing box from shaking or being damaged by external shocks during transportation and handling, some goods must be equipped with protective parts before packing them into the packing box Inside; the protective parts are traditionally made of styrofoam foam material, which provides good protection effect for goods due to the light weight, elasticity and impact resistance of styrofoam material. However, due to the disadvantages of Styrofoam material that it is not environmentally friendly and bulky, before the goods are packaged, a huge warehouse space must be prepared to store the Styrofoam foam material as a protective part.

In order to overcome the problem of using styrofoam foam as a protective part, which is not environmentally friendly and takes up too much space, there are many other product protection devices made of paper on the market, but the known paper cushioning materials are more expensive than traditional protective materials. Cushioning materials made of Lilong foam materials are much more expensive because of their complex structure and difficulty in assembly, resulting in high costs; Both transportation and storage will take up a lot of space, which is extremely uneconomical and troublesome for the factory.

The purpose of the present invention is to improve on the basis of the known paper packing box structure to form a paper protective member, so that the present invention can be flattened to reduce transportation and storage space when not in use, and can be used when it is to be used. The protective part can be quickly formed by simple assembly, and has a simple structure, low cost, and environmental protection, and has better characteristics than traditional polystyrene foam materials.

The low-cost, easy-to-assemble paper cushioning protector with high strength and impact resistance provided by the present invention is integrally formed with paper boards to include: a main board, which is a rectangular board body, on which are formed a plurality of fold lines of the main board that are spaced apart from each other and parallel To form the first board, the second board, the third board and the fourth board arranged in sequence, the main board can be bent to form a main rectangular frame by the folding lines of the main board, wherein the first board is symmetrically opposite The two sides are respectively bendably connected to the first side plate and the fifth side plate, and the first side plate and the fifth side plate are respectively formed with a plurality of folding lines parallel to the connecting edge with the first plate, so that the first side plate The side plate and the fifth side plate can be bent to form a first side frame body and a fifth side frame body respectively, wherein a first adhesive layer is provided on the first side plate, and a protruding plate is formed on one end of the first plate; The symmetrical opposite sides of the second plate are respectively bendably connected to the second side plate and the sixth side plate, and the second side plate and the sixth side plate are respectively formed with A plurality of folding lines on the edge allow the second side panel and the sixth side panel to be bent to form the second side frame body and the sixth side frame body respectively, wherein the second side panel is provided with a second adhesive layer; The symmetrical opposite sides of the third plate are respectively bendably connected to the third side plate and the seventh side plate, and the third side plate and the seventh side plate are respectively formed with a plurality of strips parallel to the connecting edge with the third plate folding line, so that the third side plate and the seventh side plate can be bent to form the third side frame body and the seventh side frame body, wherein, the third side plate is provided with a third adhesive layer; the fourth plate is symmetrical The opposite two sides are respectively bendably connected to the fourth side plate and the eighth side plate, and the fourth side plate and the eighth side plate are respectively formed with a plurality of folding lines parallel to the connecting edge with the fourth plate, so that the first The four side panels and the eighth side panel can be bent to form the fourth side frame body and the eighth side frame body, wherein, the fourth side panel is provided with a fourth adhesive layer; wherein, when the first side panel and the fifth side panel When the side panels are respectively bent to form the first side frame body and the fifth side frame body and are both accommodated in the main rectangular frame body, the first side frame body and the fifth side frame body are connected by the first adhesive layer. The opposite surfaces are adhered and fixed to each other; wherein, when the second side plate and the sixth side plate are respectively bent to form the second side frame body and the sixth side frame body and are both accommodated in the main rectangular frame, by the second The adhesive layer adheres and fixes the opposite surfaces of the second side frame and the sixth side frame; wherein, when the third side plate and the seventh side plate are respectively bent to form the third side frame and the seventh side frame body and are both accommodated in the main rectangular frame, the opposite surfaces of the third side frame and the seventh side frame are adhered and fixed to each other by the third adhesive layer; wherein, when the fourth side plate and the first When the eight side panels are respectively bent to form the fourth side frame and the eighth side frame and are all accommodated in the main rectangular frame, the fourth side frame and the eighth side frame are connected by the fourth adhesive layer The opposite surfaces of each other are adhered and fixed; and wherein a first side frame body, the second side frame body, the third side frame body and the fourth side frame body are jointly formed in the main rectangular frame body to form a first A buffer positioning part, and a second buffer positioning part is jointly formed in the main rectangular frame by the fifth side frame body, the sixth side frame body, the seventh side frame body and the eighth side frame body. Due to the structure of the protector, the paper protector can be folded into a flat state for transportation and storage when not in use for packaging goods, and can quickly assemble, fix and match the goods when packaging is required, and Simple structure, low cost and environmental protection.

In one embodiment, the first side panel, the third side panel, the fifth side panel and the The seven side panels have the same first width, the second side panel, the fourth side panel, the six side panels and the eighth side panel have the same second width, and the second width is smaller than the first width.
