Elastic composite structure having low-density foam material and reinforcement structure, and anti-collision packing object including the same

Abstract

An anti-collision packing object includes at least one base portion and at least one elastic composite structure that can be connected to the base portion and includes at least one main body and at least one reinforcement structure. The main body can made of a low-density foam material having a density lower than 30 kg/m 3 . The reinforcement structure can be made of a paper material, a plastic material, a softwood material, etc., and can be placed in the main body, so that the structural strength of the low-density foam material is enhanced to allow a higher vertical compressive strength for the elastic composite structure and to provide better cushioning effects and supporting strength.

What is claimed is: 
     
         1 . An elastic composite structure, comprising:
 at least one main body formed with at least one opening and made of a low-density foam material having a density lower than 30 kg/m 3 ; and   at least one reinforcement structure made of a material including at least one of a paper material, a plastic material and a softwood material, in a columnar shape or formed as a plate, and configured to be inserted into the opening to be placed in the main body.   
     
     
         2 . The elastic composite structure according to  claim 1 , wherein the opening is adjacent to a corner of the main body. 
     
     
         3 . The elastic composite structure according to  claim 1 , wherein the reinforcement structure is made of corrugated paperboard. 
     
     
         4 . The elastic composite structure according to  claim 3 , wherein a bursting strength of the corrugated paperboard is 4-12 kgf/cm 2 . 
     
     
         5 . The elastic composite structure according to  claim 3 , wherein a thickness of the reinforcement structure is 2-4 mm. 
     
     
         6 . The elastic composite structure according to  claim 1 , wherein the reinforcement structure is shaped as a triangular column. 
     
     
         7 . An anti-collision packing object configured to be placed in a case and including at least one base portion and the elastic composite structure according to  claim 1  that is disposed on the base portion. 
     
     
         8 . The anti-collision packing object according to  claim 7 , wherein the base portion is made of a paper material. 
     
     
         9 . The anti-collision packing object according to  claim 7 , wherein the base portion is made of a foam material. 
     
     
         10 . The anti-collision packing object according to  claim 7 , wherein the elastic composite structure is configured to be placed between the case and the base portion.
