Angled cushioning structure for packaging

Abstract

An angled cushioning structure for packaging includes a cushioning body, a first side plate and a second side plate. The cushioning body includes a bending line , which includes a plurality of connecting sections and a plurality of protruding cut sections arranged at an interval. The first and second side plates are connected to two opposite sides of the cushioning body, respectively. The first and second side plates are bent towards the cushioning body to become overlapped, and the bending line on the cushioning body is bent. Thus, a position at which the cushioning body corresponds to each protruding cut section forms an assembly space for locking and fastening the first or second fastening portion therein. The cushioning body is caused to have a bending angle after the first and second fastening portions are locked and fastened in the assembly space.

What is claimed is: 
     
         1 . An angled cushioning structure for packaging, comprising:
 a cushioning body, comprising a bending line connecting two opposite sides of the cushioning body, the bending line comprising a plurality of connecting sections and a plurality of protruding cut sections arranged at an interval, openings of two of the protruding cut sections being in different directions; and   a first side plate and a second side plate, connected to two corresponding sides of the cushioning body parallel to the bending line, respectively, the first side plate comprising a first fastening portion disposed in a protruding manner at one side of the first side plate away from the cushioning body and disposed correspondingly to one of the protruding cut sections, the second side plate comprising a second fastening portion disposed in a protruding manner at one side of the second side plate away from the cushioning body and disposed correspondingly to one of the protruding cut sections;   wherein, when the first side plate and the second side plate are bent towards the cushioning body to become overlapped, the bending line on the cushioning body is bent to cause a position at which the cushioning body corresponds to each protruding cut section to form an assembly space for locking and fastening the first fastening portion or the second fastening portion therein, and the cushioning body is caused to have a bending angle after the first fastening portion and the second fastening portion are locked and fastened in the assembly space.   
     
     
         2 . The angled cushioning structure for packaging of  claim 1 , wherein the first side plate comprises a first abutting section, which is disposed in a protruding manner at one side of the first side plate away from the cushioning body and connected to the first fastening portion, and abuts against the cushioning body when the first side plate is bent towards the cushioning body. 
     
     
         3 . The angled cushioning structure for packaging of  claim 2 , wherein a distance by which the first protruding portion protrudes out of the first side plate is greater than a distance by which the first abutting portion protrudes out of the first side plate. 
     
     
         4 . The angled cushioning structure for packaging of  claim 2 , wherein the second side plate comprises a first abutting section, which is disposed in a protruding manner at one side of the second side plate away from the cushioning body and connected to the second fastening portion, and abuts against the cushioning body when the second side plate is bent towards the cushioning body. 
     
     
         5 . The angled cushioning structure for packaging of  claim 4 , wherein a distance by which second protruding portion protrudes out of the second side plate is greater than a distance by which the second abutting portion protrudes out of the second side plate. 
     
     
         6 . The angled cushioning structure for packaging of  claim 1 , wherein the first fastening portion comprises an inclined surface at the end away from the cushioning body, and the second fastening portion comprises the inclined surface at the end away from the cushioning body. 
     
     
         7 . The angled cushioning structure for packaging of  claim 1 , wherein between surfaces of the first fastening portion and the first side plate is a drop, and between surfaces of the second fastening portion and the second side plate is the drop. 
     
     
         8 . The angled cushioning structure for packaging of  claim 1 , wherein the cushioning body, the first side plate and the second side plate are a formed integral. 
     
     
         9 . The angled cushioning structure for packaging of  claim 1 , wherein the connecting sections on the bending line are in a semi-detached form after having been cut, and the protruding cut sections are in a fully detached form. 
     
     
         10 . The angled cushioning structure for packaging of  claim 8 , wherein the first side plate is connected to the cushioning body by a first bending line, and the second side plate is connected to the cushioning body by a second bending line. 
     
     
         11 . The angled cushioning structure for packaging of  claim 1 , further comprising a plurality of connecting adhesive pads for connecting the first side plate or the second side plate to the cushioning body. 
     
     
         12 . The angled cushioning structure for packaging of  claim 1 , wherein a total width of the first side plate and the second side plate is smaller than a width of the cushioning body.
