Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and in particular to a paper buffer protection member suitable for packaging thin electronic products.

Background Art

[0002] With the development of network technology, the growth of e-commerce has become increasingly prosperous; before handing over goods to freight carriers, e-commerce operators must properly package them in packaging boxes. When packaging, generally, the goods are placed in packaging boxes, boxes, bags, etc. (hereinafter collectively referred to as packaging boxes), and then the cover plate of the packaging box is covered and then pasted and sealed with tape; other postal services are generally the same. The general structure of the packaging box is a rectangular box in a three-dimensional form formed by folding along the folding lines pre-formed on the paper board, and then the three-dimensional packaging box is glued and fixed with adhesive.

[0003] As Figure 1 and Figure 2 shown, the general structure of the packaging box has a main board A. On the same side of the main board A, a first side board A1, a second side board A2, a third side board A3, and a fourth side board A4 are sequentially foldably formed. On the same other side, a fifth side board A5, a sixth side board A6, a seventh side board A7, and an eighth side board A8 are sequentially foldably formed. And the first side board A1 corresponds to the fifth side board A5, the second side board A2 corresponds to the sixth side board A6, the third side board A3 corresponds to the seventh side board A7, and the fourth side board A4 corresponds to the eighth side board A8. One end of the main board A forms a protruding board A9; with this structure, after folding along the folding lines (such as the dotted lines shown in Figure 1 ), a rectangular box in a three-dimensional form can be formed, and then adhesive is applied to the protruding board A9 and the protruding board A9 is adhered to the other end of the main board A to fix the three-dimensional packaging box.

[0004] In order to prevent the electronic products placed in the packaging box from being damaged due to shaking or external impact during transportation and handling, some electronic products must be equipped with protection members before being packed into the packaging box; traditionally, the protection members are mainly made of polystyrene foam materials, and the light weight and impact resistance of the polystyrene materials provide good protection effects for electronic products. However, since the disadvantage of the polystyrene material is that it does not meet environmental protection specifications and has a large volume, before packaging the electronic products, a large amount of warehouse space must be prepared to store the polystyrene foam materials as protection members.

[0005] In order to overcome the problems of environmental unfriendliness and excessive space occupation of Styrofoam foam materials as protective components, many electronic product protection devices made of paper materials are provided in the market. However, the known paper cushioning materials are much more expensive than the cushioning materials made of traditional Styrofoam foam materials, etc., because of problems such as high costs due to complex structures and difficult assembly. For example, if paper cushioning material manufacturers are required to pre-assemble in a three-dimensional shape during production, it will occupy a large amount of space during transportation and storage, which is extremely uneconomical and causes great trouble to commercial factories.

[0006] In addition, for the packaging of thin electronic products such as notebook computers, tablet computers, flat-panel TVs, etc., because better protection is needed to avoid damage to electronic products, the traditional packaging cushioning materials are even more insufficient in terms of the protective force of the structure.

Summary of the Invention

[0007] The object of the present invention is to improve on the basis of the known paper packaging box structure to form a paper protective component suitable for the packaging of thin electronic products, so that the present invention can be flattened to reduce transportation and storage space when not in use, and when in use, a cushioning protective component can be quickly formed through simple assembly. It has a simple structure, low cost, and meets environmental protection specifications, and has more excellent product characteristics compared with traditional Styrofoam foam materials.

[0061] Embodiment 1

[0062] Figure 3 and Figure 4 shown are respectively the plan view and three-dimensional view of the planar unfolded form of the buffer protection part of the present invention after being cut from a paper board and then further stamped and formed by a machine. Through the formed plural broken lines (such as Figure 3 and Figure 4As shown by the dashed lines in [Figure 0], the paper material forms a main board 1, a first side plate 11, a second side plate 12, a third side plate 13, a fourth side plate 14, a fifth side plate 15, a sixth side plate 16 and a protruding plate 17. Among them, the main board 1 is basically a long rectangular plate body, on which there are formed a first folding line 1A, a second folding line 1B, a third folding line 1C and a fourth folding line 1D that are spaced apart from each other and parallel.

And the protruding plate 17 is connected to one end of the first plate 10A by the fourth folding line 1D.

[0063] The two opposite sides of the first plate 10A in the length direction X are respectively foldably connected to the first side plate 11 and the fifth side plate 15 by folding lines. Among them, there are formed a plurality of folding lines parallel to the connecting side of the first plate 10A (i.e., parallel to the width direction Y) on the first side plate 11. By the plurality of folding lines parallel to each other distributed on the first side plate 11, the first side plate 11 is partitioned into a first side surface 111 of the first side plate, a second side surface 112 of the first side plate, a third side surface 113 of the first side plate, and a fourth side surface 114 of the first side plate that are arranged in sequence from the direction away from the first plate 10A (i.e., the length direction X) (as Figure 4 shown); the lengths of the first side surface 111 of the first side plate, the second side surface 112 of the first side plate, the third side surface 113 of the first side plate, and the fourth side surface 114 of the first side plate can all be the same, so that the first side plate 11 can be bent into a first side frame body with a square end face, or the first side surface 111 of the first side plate and the third side surface 113 of the first side plate have the same smaller length, while the second side surface 112 of the first side plate and the fourth side surface 114 of the first side plate have the same larger length, so that the first side plate 11 can be bent into a first side frame body 11A with a rectangular end face (as Figures 6 to 11as shown); in addition, a plurality of first inserting plates 115 may be further disposed on the third side surface 113 of the first side plate.

A plurality of folding lines parallel to the connection edge with the first plate 10A (i.e., parallel to the width direction Y) are formed on the fifth side plate 15. The fifth side plate 15 is partitioned by the plurality of parallel folding lines distributed on the fifth side plate 15 into a first side surface 151 of the fifth side plate, a second side surface 152 of the fifth side plate, a third side surface 153 of the fifth side plate, and a fourth side surface 154 of the fifth side plate, which are arranged in sequence in the direction away from the first plate 10A (i.e., the length direction X); the lengths of the first side surface 151 of the fifth side plate, the second side surface 152 of the fifth side plate, the third side surface 153 of the fifth side plate, and the fourth side surface 154 of the fifth side plate may be all the same, so that the fifth side plate 15 can be bent into a fifth side frame body with a square end surface, or the first side surface 151 of the fifth side plate and the third side surface 153 of the fifth side plate have the same larger length, while the second side surface 152 of the fifth side plate and the fourth side surface 154 of the fifth side plate have the same smaller length, so that the fifth side plate 15 can be bent into a fifth side frame body 15A with a rectangular end surface (as Figures 6 to 11 shown). Furthermore, the first side plate 11 has a first width W1, the fifth side plate 15 has a fifth width W5, and the first width W1 of the first side plate 11 is less than the fifth width W5 of the fifth side plate 15; in addition, a plurality of first inserting holes 155 may be further disposed on the third side surface 153 of the fifth side plate. The first inserting hole 155 is preferably a long and narrow hole cut on the third side surface 153 of the fifth side plate by stamping technology for the first inserting plate 115 to pass through, and the width of the first inserting hole 155 is greater than or equal to the width of the neck portion a, so that the first inserting plates 115 are not easily separated from each other after passing through the first inserting holes 155.

[0083] Embodiment III

[0084] As Figure 25 shown, the difference between Embodiment III and Embodiment I is that each of the first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 has at least one fitting structure 4 formed by bending for fitting and supporting non-planar protruding components. The fitting structure 4 is one of a round hole, an oblong hole, an oval hole, a rectangular oval hole, a rectangular hole, a round hole with a plurality of teeth 41 provided on one side inside the hole, an oblong hole with a plurality of teeth 41 provided on one side of the circular edge inside the hole, an oval hole with a plurality of teeth 41 provided on one side of the elliptical edge inside the hole, and a rectangular oval hole with a plurality of teeth 41 provided on one side of the elliptical edge inside the hole. The hole structure 41 involves the first side, the second side and / or the third side of the first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14, and there is no interference with the jack or the plug board. The number of the fitting structures 4 provided on the same side plate is set according to the positions and the number of the non-planar protruding components on the electronic product 2. Taking the fitting structure 4 as an oval hole with a plurality of teeth 41 provided on one side of the elliptical edge involving the first side and the second side as an example, the provision of a plurality of teeth 41 can not only facilitate the smooth loading of the electronic product 2 with non-planar protruding components into the protection member, but also increase the stability of the electronic product 2 after being loaded into the protection member. Since some thin electronic products mainly have protruding components on both sides, in this embodiment, the fitting structures 4 are only provided on the first side plate 11 and the third side plate 13.

[0085] Embodiment IV

[0086] As Figure 26As shown, the difference between the third embodiment and the first embodiment lies in that each of the first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 has at least one adaptation structure 4 formed after bending for adapting to and supporting non-planar protruding components. The adaptation structure 4 is one of the following hole structures 41: a round hole, an oblong hole, an oval hole, a rectangular-oval hole, a rectangular hole, a round hole with a plurality of teeth 42 provided on one side inside the hole, an oblong hole with a plurality of teeth 42 provided on the circular edge on one side inside the hole, an oval hole with a plurality of teeth 42 provided on the oval edge on one side inside the hole, or a rectangular-oval hole with a plurality of teeth 42 provided on the oval edge on one side inside the hole. The hole structure 41 involves the first side, the second side and / or the third side on the first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14. The number of adaptation structures 4 provided on the same side plate is set according to the positions and numbers of the non-planar protruding components on the electronic product 2. Taking the oval hole with a plurality of teeth 42 provided on the oval edge on one side inside the hole involving the first side and the second side as an example of the adaptation structure 4 of the present invention, the provision of a plurality of teeth 42 can not only facilitate the smooth insertion of the electronic product 2 with non-planar protruding components into the protective member, but also increase the stability of the electronic product 2 after being inserted into the protective member. Since some thin electronic products mainly have protruding components on both sides, in this embodiment, the adaptation structures 4 are only provided on the first side plate 11 and the third side plate 13.

[0087] The above are only preferred embodiments for explaining the present invention, and are not intended to limit the present invention in any form. Therefore, any modification or change made to the present invention under the same creative spirit should still be included in the scope intended to be protected by the present invention.
