Description

BACKGROUND

Technical Field

The present invention relates to the packing field, and in particular, to a heterogeneous composite cushioning packing box and a heterogeneous composite cushioning structure used thereby.

Related Art

At the back end of modern industry, before shipment, packing needs to be performed by using paper boxes or paper cases for stacking and transportation. Cushioning packing materials are bundled for objects in the paper boxes or paper cases to avoid sliding and vibration during transportation, so that breakage of the objects can be avoided. Common cushioning materials include expandable polystyrene (EPS), foamed plastics, air column sheets, soft cushions, molded pulps, paper fillers, and the like.
However, with the increasing awareness of environmental protection, currently, the regulations on packing in countries all over the world tend to be strict. For example, it is required that the cushioning packing materials used are materials that can be naturally decomposed or the use quantity of cushioning packing materials is reduced. Therefore, the use quantity of cushioning packing materials that can be hardly naturally decomposed or recycled, for example, materials such as EPS and foamed plastics, is gradually limited.
Different packing materials have different material properties, and have advantages as well as disadvantages. Therefore, under the premise that the packing regulations tend to be strict, it is difficult to satisfy both the supporting and cushioning effects. For example, the EPS can provide stable supporting and cushioning effects, but a disadvantage of the EPS is that when the EPS is subject to a force and is damaged, the EPS will rupture and break. Therefore, when the EPS breaks, corners wrapped by the EPS cannot be protected through cushioning, and the object is easily subject to an external force and gets damaged. In addition, the EPS needs mold opening and precasting, and has relatively high costs. For another example, an air column sheet has good force dispersion, a relatively good cushioning effect, and a low price, and is convenient for transportation, but the air column sheet alone cannot be completely adhered to the object, and does not have sufficient supporting.

DETAILED DESCRIPTION

FIG. 1 is a schematic perspective view of a first embodiment of a heterogeneous composite cushioning packing box. FIG. 2 is a schematic perspective view of the first embodiment of a heterogeneous composite cushioning packing box. As shown in FIG. 1 and FIG. 2, the heterogeneous composite cushioning packing box 1 includes an outer box 200 and a plurality of cushioning structures 101 and 103. Herein, for example, the heterogeneous composite cushioning packing box 1 is a packing flat panel display 500, but actually is not limited thereto. As shown in FIG. 1 and FIG. 2, the outer box 200 includes a bottom surface 210, a top surface 220, first side surfaces 230, and second side surfaces 240. Each first side surface 230 is connected to the bottom surface 210 and the second side surfaces 240, the two first side surfaces 230 are opposite to each other, and the two second side surfaces 240 are opposite to each other. The top surface 220 is connected to the first side surfaces 230 and the second side surfaces 240. The bottom surface 210, one of the first side surfaces 230, and one of the second side surfaces 240 enclose a bottom angle accommodating area 251. The top surface 220, one of the first side surfaces 230, and one of the second side surfaces 240 enclose a vertex angle accommodating area 253.
Herein, the cushioning structure 101 is a corner column type cushioning structure, and the cushioning structure 103 is a base type cushioning structure. The cushioning structures 101 and 103 are fastened in the vertex angle accommodating area 253 and the bottom angle accommodating area 251. The cushioning structure 101 is fastened in the vertex angle accommodating area 253. The cushioning structure 103 is fastened in a space formed by the bottom surface 210, the first side surfaces 230, and the second side surfaces 240, and two ends of the cushioning structure 103 are fastened in the bottom angle accommodating area 251. The cushioning structure 103 may be an elongated structure with a recessed middle part, and may further extend upward at two ends, so that presents a concave structure in appearance. The materials of the cushioning structures 101 and 103 are different from the material of the outer box 200. Herein, the material of the outer box 200 may be a high-strength corrugated paper board, or the like, to provide relatively high rigidity and strength. The cushioning structure 101 may be an air column base, and the cushioning structure 103 may be EPS. This is an example herein. The cushioning structures 101 and 103 may be molded pulps, EPS, air column bases, foamed plastics, or the like, to provide cushioning at the bottom or the corner. In this way, a heterogeneous composite structure is achieved by means of a combination of a cushioning structure and an outer box, and supporting strength and cushioning of impact force are also provided.
FIG. 3 is a schematic perspective view of a second embodiment of a heterogeneous composite cushioning packing box. Further, cushioning structures 102 and 104 of the heterogeneous composite cushioning packing box 1 may also be directly heterogeneous composite cushioning structures. An outer box 200 is wrapped outside the cushioning structures 102 and 104. As shown in FIG. 3, the corner column type cushioning structure 102 includes a supporting body 10 and a cushioning base 20. The supporting body 10 and the cushioning base 20 are different materials, and provide supporting and cushioning functions. The base type cushioning structure 104 includes a supporting body 10 and two cushioning bases 20. Herein, to facilitate differentiation, the two cushioning bases 20 are defined as a first cushioning base 20 and a second cushioning base 30. The second cushioning base 20 and the third cushioning base 30 are fastened on two sides inside the supporting body 10.
FIG. 4 is a schematic perspective view of a third embodiment of a heterogeneous composite cushioning packing box. FIG. 5 is a schematic perspective view of a fourth embodiment of a heterogeneous composite cushioning packing box. As shown in FIG. 4 and FIG. 5, in addition to manners of the first embodiment and the second embodiment, as shown in FIG. 4, a base type cushioning structure 102 may be further fastened on two upper sides of an outer box 200, and as shown in FIG. 5, a base type cushioning structure 103 may alternatively be fastened on left and right sides of the outer box 200.
Further, referring to FIG. 1 and FIG. 2 again, the heterogeneous composite cushioning packing box 1 further includes a cushion sheet 40. The cushion sheet 40 may be fastened on the first side surface 230 of the outer box 200, or may be fastened on a wall surface of the base type cushioning structure 104, to provide surface wrapping for the flat panel display 500, to cushion the impact force. The heterogeneous composite cushioning packing box 1 is merely an example, and this application is not limited thereto. Actually, adjustment may be further performed based on the shape and the weight of an object to be packed. For example, four cushioning structures 102 may alternatively be fastened only in the bottom angle accommodating area 251 and the vertex angle accommodating area 253.
The cushioning structure will be described more specifically below. FIG. 6 is a schematic exploded view of a first embodiment of a heterogeneous composite cushioning structure. FIG. 7 is a schematic stereogram of the first embodiment of a heterogeneous composite cushioning structure. FIG. 8 is a schematic top view of the first embodiment of a heterogeneous composite cushioning structure. As shown in FIG. 6 to FIG. 8, the heterogeneous composite cushioning structure 100 of the first embodiment may be a corner column type cushioning structure and includes a supporting body 10 and a cushioning base 20. The supporting body 10 includes a bottom wall 11, a first side wall 13, a second side wall 15, and a third side wall 17. The first side wall 13, the second side wall 15, and the third side wall 17 are located on the bottom wall 11. The first side wall 13 and the third side wall 17 are respectively connected to two sides of the second side wall 15. The bottom wall 11, the first side wall 13, the second side wall 15, and the third side wall 17 enclose an accommodating area 111. The cushioning base 20 is fastened in the accommodating area 111, and the cushioning base 20 includes a cushioning bottom wall 21 and a cushioning side edge 23. The cushioning bottom wall 21 is in contact with the bottom wall 11, the cushioning side edge 23 is located on a part of a periphery of the cushioning bottom wall 21, and is in contact with the first side wall 13, the second side wall 15, and the third side wall 17, and the first cushioning side edge 23 encloses a first clamping opening 231. In addition, the material of the cushioning base 20 is different from the material of the supporting body 10, so that materials suitable for supporting and cushioning are used based on factors such as the shape and weight of the object.
As shown in FIG. 6 to FIG. 8, referring to both FIG. 1 and FIG. 2, corners of the object and the flat panel display 500 may be clamped to the clamping opening 231. In this embodiment, the supporting body 10 is formed by a paper board, and the paper board may be a high-strength corrugated paper board, and may be a part of the outer box 200. That is, the heterogeneous composite cushioning structure 100 of the first embodiment may be formed by using a part of the outer box 200 of FIG. 1 as the supporting body 10, and using the cushioning structure 101 of FIG. 1 as the cushioning base 20. Herein, support for the corner of the object can be provided by means of better rigidity and strength of the corrugated paper board. The first side wall 13, the second side wall 15, and the third side wall 17 of the supporting body 10 enclose a concave shape herein, and enclose the accommodating area 111. The first side wall 13 and the third side wall 17 are mirrored. However, this is only an example, and this application is not limited thereto. In addition, the cushioning base 20 is an air column base with a bent and formed air column sheet. The air column base may include a plurality of air columns independent of each other, and therefore when an external force is received, breakage of a single air column does not cause complete damage of the overall cushioning effect. In addition, the volume can be adjusted by using an air column, so that the cushioning base 20 is fastened and clamped in the accommodating area 111. The cushioning side edge 23 of the cushioning base 20 may be a single-sheet air column, or may be a multi-sheet air column. Herein, the cushioning side edge 23 encloses an arc-shaped clamping opening 231, and the direction of the clamping opening 231 is approximately the same as the direction of the concave shape enclosed by the first side wall 13, the second side wall 15, and the third side wall 17. When the corner of the object is clamped to the clamping opening 231, the air column can tightly wrap the corner of the object. This is merely an example herein, and this application is not limited thereto.
FIG. 9 is a schematic exploded view of a second embodiment of a heterogeneous composite cushioning structure. FIG. 10 is a schematic stereogram of the second embodiment of a heterogeneous composite cushioning structure. FIG. 11 is a schematic top view of the second embodiment of a heterogeneous composite cushioning structure. As shown in FIG. 9 to FIG. 11, also referring to FIG. 2, the heterogeneous composite cushioning structure 102 of the second embodiment is also a corner column type cushioning structure. The heterogeneous composite cushioning structure 102 includes a supporting body 10 and a cushioning base 20. A supporting body 10 of the second embodiment is made from EPS. The cushioning base 20 is an air column base with a bent and formed air column sheet, and is fastened in an accommodating area 111. The structure is suitable to support an object with a larger height and a large area. In addition, a first side wall 13 and a third side wall 17 of the supporting body 10 further include fastening blocks 131 and 171. The fastening blocks 131 and 171 extend toward the accommodating area 111 respectively from the first side wall 13 and the third side wall 17, so as to limit the cushioning base 20, thereby preventing the cushion base 20 from separating with the supporting body 10. The fastening blocks 131 and 171 may be integrally formed when EPS is precast. Further, the heterogeneous composite cushioning structure 102 of the second embodiment has a cushioning base 20, and the supporting body 10 can reduce the thickness of the first side wall 13, the second side wall 15, and the third side wall 17. Therefore, use of EPS (EPS) can be reduced, material costs can be reduced, and environmental problems about subsequent recycling are also reduced. In addition, the cushioning base 20 is an air column base, and a gap of the precast supporting body 10 may be filled by means of inflation, to further achieve a cushioning effect.
FIG. 12 is a schematic exploded view of a third embodiment of a heterogeneous composite cushioning structure. FIG. 13 is a schematic stereogram of the third embodiment of a heterogeneous composite cushioning structure. The heterogeneous composite cushioning structure 105 of the third embodiment is opposite to the heterogeneous composite cushioning structure 100 of the first embodiment, and the heterogeneous composite cushioning structure 102 of the second embodiment. A supporting body 10 thereof is an air column base, and a cushioning base 20 is precast EPS, a molded pulp, or a paper board. By using this implementation, the cushioning base 20 can be attached more closely to an edge of an object, for example, the flat panel display 500, or moderate a sharp part, shape an irregular shape, or increase the overall thickness, and the external supporting body 10 can support the cushioning base 20, so that the cushioning base 20 does not easily fall off or get broken. A double-effect of supporting and cushioning can also be achieved.
The foregoing first embodiment, second embodiment, and third embodiment are merely examples, and are not intended for limitation. The supporting body 10 may be a paper board, a molded pulp, EPS, an air column base, or a combination thereof. The cushioning base 20 may be an air column base, foamed plastic, EPS, or a combination thereof. In this way, materials suitable for supporting and cushioning can be selected for different objects.

FIG. 15 is a schematic top view of the fourth embodiment of a heterogeneous composite cushioning structure. As shown in FIG. 14 and FIG. 15, also referring to FIG. 2, the heterogeneous composite cushioning structure 104 of the fourth embodiment may be a base type cushioning structure. In addition, the heterogeneous composite cushioning structure 104 of the fourth embodiment may be considered as extending in two directions in the first embodiment or the second embodiment. In the fourth embodiment, the heterogeneous composite cushioning structure 104 include a supporting body 10, a first cushioning base 20, and a second cushioning base 30. Herein, actually, the first cushioning base 20 and the foregoing cushioning base 20 indicate the same cushioning base. However, for ease of subsequent descriptions, "first" is added to facilitate differentiation from the second cushioning base 30. In addition, the structure of the first cushioning base 20 is approximately the same as the structure of the second cushioning base 30, but the placing directions are different.
In the fourth embodiment, the supporting body 10 of the heterogeneous composite cushioning structure 104 includes a bottom wall 11, a first side wall 13, a second side wall 15, a third side wall 17, and a fourth side wall 19.

The first side wall 13 and the third side wall 17 are respectively connected to two sides of the second side wall 15. In addition, the fourth side wall 19 is connected to the other side of the first side wall 13 and the other side of the third side wall 17 relative to the second side wall 15. The bottom wall 11, the first side wall 13, the second side wall 15, and the third side wall 17 enclose a first accommodating area 111. The bottom wall 11, the first side wall 13, the third side wall 17, and the fourth side wall 19 enclose a second accommodating area 113. Herein, the first accommodating area 111 and the second accommodating area 113 may be opposite to each other, and may be further mirrored. However, this is merely an example, and this application is not limited thereto. Further, the supporting body 10 may also be a part of the outer box 200 in FIG. 1.
The first cushioning base 20 is fastened in the first accommodating area 111, and the second cushioning base 30 is fastened in the second accommodating area 113.
