Besides, the first baseboard 111 and the second baseboard 112 are foldable along a junction of the first baseboard 111 and the second baseboard 112. One side of the third baseboard 113 is joined to the second baseboard 112. The second baseboard 112 and the third baseboard 113 are foldable along a junction of the second baseboard 112 and the third baseboard 113. One side of the forth baseboard 114 is joined to the third baseboard 113. The third baseboard 113 and the fourth baseboard 114 are foldable along a junction of the third baseboard 113 and the fourth baseboard 114. One side of the fifth baseboard 115 is joined to the fourth baseboard 114. The fourth baseboard 114 and the fifth baseboard 115 are foldable along a junction of the fourth baseboard 114 and the fifth baseboard 115. Moreover, the above-mentioned junctions are parallel to each other and these baseboards are made of cardboards. Consequentially, the buffer member 11 is formed by way of connecting the fifth baseboard 115 to the first baseboard 111 (as shown in FIG. 1).
As mentioned above, the first baseboard 111 has a baffle flap 1111 and the fifth baseboard 115 has a fastened hole 1151. For connecting the first baseboard 111 to the fifth baseboard 115, the baffle flap 1111 is inserted into the fastened hole 1151.
With reference to FIG. 3, the second portion 132 of the first supporting board 13 and the first portion 131 of the first supporting board 13 are foldable, and the first portion 131 of the first supporting board 13 is foldable along the first edge 121. When the first baseboard 111 and the fifth baseboard 115 have connected and the second portion 132 have folded to insert into the lateral side 12, the first portion 131 covers at least one portion of the lateral side 12. Then, the first portion 131 is substantially perpendicular to the second portion 132. Similarly, the forth portion 142 of the second supporting board 14 and the third portion 141 of the second supporting board 14 is foldable, and the third portion 141 of the second supporting board 14 is foldable along the second edge 122. When the forth portion 142 have folded to insert into the lateral side 12, the third portion 141 also covers at least one portion of the lateral side 12. Then, the third portion 141 is substantially perpendicular to the forth portion 142.
In conclusion, the first portion 131 of the first supporting board 13 and the third portion 141 of the second supporting board 14 are connected to the first edge 121 and the second edge 122, respectively. By folding the second portion 132 and the forth portion 142 to insert into the lateral side 12, the first portion 131 and the third portion 141 are connected with each other and cover the lateral side 12 jointly.
In addition, with reference to FIG. 1, the first supporting board 13 further has a flap 133 and the second supporting board 14 further has a hole 143. The flap 133 is inserted into the hole 143, so that the first supporting board 13 faces and connects to the second supporting board 14.
In the present embodiment, the first supporting board 13 and the second supporting board 14 respectively have a first buffer breach 134 and a second buffer breach 144. When the first supporting board 13 and the second supporting board 14 cover the lateral side 12 jointly, the first buffer breach 134 is formed on a corner of the lateral side 12 and the second buffer breach 144 is formed on another corner of the lateral side 12 (as shown in FIG. 3). These buffer breaches 134 and 144 are used to buffer the outside stress.
In addition, with reference to FIG. 3, a pair of slots 116 is formed perpendicularly to the junction of the third baseboard 113 and the fourth baseboard 114. The slots 116 are parallel to each other. With reference to FIG. 4, as a result of forming these slots, a part of the third baseboard 113 forms a first tongue flap 1131 defined by those slots 116 and a part of the forth baseboard 114 forms a second tongue flap 1141 defined by those slots 116. When the fifth baseboard 115 and the first baseboard 111 are connected to form a buffer member 11, the first tongue flap 1131 and the second tongue flap 1141 are foldable inwardly to form a mounting base.
Additionally, one end of each slot 116 is a circled end. The buffer device 10 further comprises at least one cut line 117 formed on the buffer member 11. The cut line 117 can be a curve line, a wavy line, or a saw-toothed line. The designs of the circle ends of the slots 116 and the cut line 117 are used for releasing the stress so as to improve the effect of buffering stress.
With reference to FIG. 5, a packing structure 1 according to the preferred embodiment of the invention comprises a plurality of buffer devices 10 and a bearing element 15. In this case, the buffer devices 10 are fastened to two sides of the bearing element 15 so as to assemble the packing structure 1.
In the present embodiment, the structures and the materials of the buffer devices 10 of the packing structure 1 are the same as those previously mentioned, so the detailed descriptions are omitted for concise purpose. To be noted that the laterals of the bearing element 15 are respectively fastened to the mounting base of each buffer device 10 (as shown in FIG. 6). The bearing element 15 is used to hold a product 16 to be transported. Using a pair of the packing structures to cover the top and bottom sides or the left and right sides of the product 16 can protect it from colliding stress in shipment (as shown in FIG. 7). As the packing structure 1 sheathes the laterals of the product 16, the packing structure 1 does not limit to the transported product's size. Consequently, the packing structure 1 can be applied to different sizes of products to be transported.
In conclusion, the buffer device is characterized in using the first supporting board and the second supporting board, which are both connected to the buffer member, face to each other and cover the lateral side of the buffer member. In addition, the corners of lateral side form the first buffer breach and the second buffer breach. Therefore, the buffer device can buffer the stress significantly. Moreover, in this case, at least one cut line and a slot having a circled end are formed on the buffer member to enhance the effect of buffering stress.
Therefore, a packing structure assembled with the buffer devices can be applied to package products to be transported for achieving the objective of protecting products by buffering the colliding stress. Moreover, since the buffer device can be made of cardboards, the assembling process of the buffer device is easier and the objective of environmental protection is achieved. Consequently, the invention further achieves the demand of decreasing manufacturing cost.
