For example, a condition “A or B” is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present). In addition, whenever open-ended transitional phrases are used, such as “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variant thereof, it is understood that transitional phrases such as “consisting essentially of” and “consisting of” are also disclosed and included.

[0067] In this description, the terms first, second and the like are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances, and the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein.

[0068] The following terms or definitions are provided solely to aid in the understanding of the invention. These definitions should not be construed to have a scope less than understood by a person of ordinary skill in the art.

[0069] According to the composite board structure and its box structure according to the present invention, please refer to FIG. 1A and FIG. 1B, the composite board structure includes a supporting board 10 and a structural plate 20. The supporting board 10 is essentially a flat plate shape, and the structural plate 20 has a plurality of pits 21. Therefore, the structural plate 20 will be defined a plate surface side 201 and a pit side 202. According to the structure, the pit 21 includes the pit wall 211 and the pit bottom 212. The structural plate 20 is disposed on one side of the supporting board 10 with the pit side 202 by various ways such as gluing, radio frequency bonding, ultrasonic bonding, thermal compression, clamping and the likes, which depended on the materials and applications. However, the above is only for example, and it is not limited to only adopt these methods. The materials can be plastics, papers, foamed materials, polymers, metals or a combinations thereof.

[0070] Therefore, the composite board formed by the supporting board 10 and the structural plate 20, due to the lateral structure provided by the pits 21, has improved bending resistance, external force twisting resistance and torsional strength the resistance. Please be noted that the so-called lateral structure of the pits 21 is respectively to the planes of the supporting board 10 and the structural plate 20. In other words, because the pit 21 is formed with substantially perpendicular to the surface of the structural plate 20, the supporting supporting board 10 and the structural plate 201 will inevitably form an angle with the surface of the planes (either generally or nearly perpendicular, but are not limited to being perpendicular, and the arrangement of the inclined surfaces can be employed). Therefore, when the whole composite board is bent by an external force, the pit wall 211 can provide a corresponding resistance to against the force. Therefore, the bending resistance, the external force twisting resistance and the torsional strength the resistance can be improved. It should be noted that the pit 21 is a three-dimensional columnar structure, so that the resistance provided by the pit 21 is also multi-directional.

[0071] After the supporting board 10 and the structural plate 20 are bonded, the pit bottoms 212 of the structural plate 20 and the supporting board 10 do not disengage after being bonded. Due to the tensile resistance of the supporting board 10 and the structural plate 20, combined with the bonding force between the pit bottom 212 and the supporting board 10, the bending expansion or bending compression of the surface of the supporting board 10 and the structural plate 20 will be restricted to further improve bending resistance structural performance. On the other hand, in addition to the three-dimensional structure of the pit 21 itself, due to the relationship of the multiple pits 21 on the structural plate 20, even if the force is applied without passing the position of the pit 21 (pit wall 211), rather than passes through the plane between the pits 21, it will still be restricted and influenced by the pits 21 to achieve the purpose of improving the bending resistance, the resistance to the external force distortion and the bending resistance.

[0072] Moreover, for the shape and configuration of the pits 21, in addition to the square structure in FIG. 1A as above-mentioned, it may also be circular (see FIG. 2A) or hexagonal (see FIG. 2B), long square, etc. Excepting for the regular distribution (see FIG. 1A), it may also be staggered (see FIG. 2A), or a honeycomb-like minimum packing arrangement (see FIG. 2B). Except for the shapes and arrangements described above, the present invention is not limited to such arrangements or shapes, and any other shape, arrangement is applicable. Also, the depths of the pits 21 may also be equal or unequal. The shape, and arrangement may also be a mixture of any of the foregoing types. The density of the configuration of the pits 21 can also be determined according to actual needs. As previously mentioned, when the configuration of the pits 21 is more dense, the restriction is greater between the pits 21, and the structural strength is greater. Further, referring to FIG. 2C, if the arrangement between the pits 21 is relatively loose in the case of a square and linear arrangement, the restriction between the pits 21 are relatively weaker. But if the strength of the material itself is sufficient, or where the strength requirement is lower, the arrangement can also be adapted. However, if considering the requirement of the better strength and resistance, the staggered arrangement is better (see FIG. 2A and FIG. 2B).

[0073] As for the forming of the pit 21, it is also possible to determine various methods based on different materials of the plate material, such as stamping, vacuum forming, hot pressing, radio frequency or ultrasonic pressing, rolling, direct forming, etc. Also, the present invention is not limited to such manufacturing methods, and other forming methods may also be applied.

[0074] Furthermore, the above-mentioned pits 21 are independent of each other, ie, each pit 21 is not mutually communicated with each other. In order to further increase the strength based on the same concept, referring to FIG. 3, the connecting ribs 22 would also be added between the pits 21 to connect at least two pits 2 to further increase the strength. As a result, the plane between the pits 21 is not restricted only by the pits 21, but also due to the existence of the connecting ribs 22, which further improves the strength. The depth of the connecting rib 22 may be lower than that of the pit 21, or equal. The shape and the amount of the pits to be connected are also not specifically limited. The configuration position of the connecting rib 22 can be arranged according to the position needing to be strengthened. So that It is not necessarily necessary that all the pits 21 on the structural plate 20 have the connecting ribs 22.

[0075] In addition, as shown in FIG. 4A, the pit 21 can also be in a closed annular shape. There are a protrusion 213 inside the pit 21. The shape of the protrusion 213 can be the same as or different from the pit 21, and the height of the protrusion 213 can also be equal to or less than the depth of the pit 21. Please refer to FIG. 4B, the supporting board 10 corresponding to the structural plate 20 may also have a plurality of pillars 11, and the pillars 11 can be combined (inserted) with the bottom of the protrusions 213 of the pits 21 to increase the bonding strength. Also the pillars 11 may correspond to the positions of the pits 21 or not. As described above, its shape, position, arrangement, height, etc. can be changed, and not limited to the type shown in the figures.

[0076] On the other hand, the above-mentioned pits 21, the protrusions 213, the pillars 11 or the structural plate 20 can be punched to form different perforations on the wall, bottom, or the surface to increase the strength and greatly reduce used materials.

[0077] Furthermore, please refer to FIG. 5A, if it is a thick plate (for example, a foamed material), it can be formed by hot pressing, direct forming, etc., to form a structural plate 20 with pits 21. Also, if the side wall of the pit 21 is hollowed out, it will form a structure similar to that shown in FIG. 1A and FIG. 1B. The structural plate 20 can also be punched directly to form the perforation 214, as shown in FIG. 6, which can also achieve the purpose of reducing the amount of material used while providing the ability to resist bending, external force twisting and torsion. Variations of the remaining arrangements, shapes, positions, etc. may be altered as previously described, and will not be repeated herein.

[0078] The box made of the composite board of any one of the foregoing embodiments, please refer to FIG. 7, which can replace the most common corrugated paper box. The strength can be greatly improved, the usage amount of the material is reduced, and the specific strength is high. And if the box is made of a waterproof material, the waterproof and moisture-proof performance are achieved. And the box has more durable performance, which is quite conducive to repeated use.

[0079] Please refer to FIG. 8, which is another embodiment of the present invention. The box structure is formed by only one layer of a structural plate 20 (also referred to as a structural sheet) of the composite plate of any one of the foregoing embodiments. Likewise, the structural plate 20 has a plurality of pits (also referred to as pit bodies) 21. Because of the lateral structure provided by the pits 21, the resistance to bending, external force twisting and torsional resistance can be improved. Please be noted that the so-called lateral structure of the pits 21 is respectively to the plane of the structural plate 20. In other words, because the pit 21 is formed with substantially perpendicular to the surface of the structural plate 20, the structural plate 201 will inevitably form an angle with the surface of the planes (either generally or nearly perpendicular, but are not limited to being perpendicular, and the arrangement of the inclined surfaces can be employed). Therefore, when the whole box structure is applied by an external force or a loading, the pit wall 211 can provide a corresponding resistance to against the force or the loading. Therefore, the bending resistance, the external force twisting resistance and the torsional strengththe resistance can be improved. Therefore, this box can replace the most common corrugated paper box. The strength can be greatly improved, the usage amount of the material is reduced, and the specific strength is high. The difficulty of production is significantly reduced, which is beneficial to improve production efficiency. And if the box is made of a waterproof material, the waterproof and moisture-proof performance are achieved. And the box has more durable performance, which is quite conducive to repeated use.

[0080] The box is formed by folding a single structural plate 20, and connecting at the joint, or directly engaging with a plurality of structural plates 20. The bonding method between the structural plates 20 does not need to be limited, and can be used, for example, for thermal bonding, adhering, clamping, locking, nailing and the like. In addition, the reinforcing strips 23 can be used to reinforce between adjacent structural plates 20, and the reinforcing strips 23 can even be extended to form a frame plate 24, as shown in FIG. 9.

[0081] In addition, please refer to FIG. 10, if the pits 21 on the structural plate 20 are directional (for example, the elongated strips as shown in the figure). In order to balance the stress and increase the strength, the pits 21 of adjacent structural plates 20 have different orientations or types. FIG. 10 is merely an illustration, which may be any shape and arrangement configuration, in addition to the aforementioned regular patterns, other irregular or non-geometric patterns or logos, special trademarks, patterns, etc. and whose depth, position, angle can be varied. The design and configuration can also be modified according to the requirements of each face. For example, the bottom surface can be designed with high-strength patterns and configurations (such as hexagonal honeycomb arrangement), and the side surface can be configured with medium-strength patterns or arrangements, and the top surface can also be designed as LOGO, special trademark, pattern, etc. Furthermore, as shown in FIG. 11, the pits 21 of the adjacent structural plates 20 are engaged with each other at a contact location of the interior of the box to further improve the strength of the engagement and the whole box, or can replace the reinforcing strips 23 or the frame plates 24, etc.

[0082] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims
