Transport box

Abstract

A transport box includes: an outer box formed in a rectangular parallelepiped shape and capable of packing a packed object; and a buffer body disposed between the outer box and the packed object, wherein the buffer body includes medium enclosing buffer members having a resin sheet welded in a bag shape and a medium sealed in the resin sheet, each medium enclosing buffer member of the medium enclosing buffer members includes buffer parts each having a bag shape and enclosing a medium, and a communication flow path that allows the buffer parts adjacent to each other to communicate with each other, the buffer parts are disposed in a straight line, the communication flow path is formed between the buffer parts adjacent to each other and is bendable, and each of the medium enclosing buffer members is disposed in the outer box.

What is claimed is: 
     
         1 . A transport box comprising:
 an outer box formed in a rectangular parallelepiped shape and capable of packing a packed object; and   a buffer body disposed between the outer box and the packed object,   wherein the buffer body includes   a plurality of medium enclosing buffer members having a resin sheet welded in a bag shape and a medium sealed in the resin sheet,   each medium enclosing buffer member of the plurality of medium enclosing buffer members includes   a plurality of buffer parts each having a bag shape and enclosing a medium, and   a communication flow path that allows the buffer parts adjacent to each other among the plurality of buffer parts to communicate with each other,   the plurality of buffer parts is disposed in a straight line,   the communication flow path is formed between the buffer parts adjacent to each other and is bendable, and   each of the medium enclosing buffer members is disposed in the outer box in a state where the buffer parts of the medium enclosing buffer member is in contact with one of six inner surfaces of the outer box and the communication flow path is bent.   
     
     
         2 . The transport box according to  claim 1 , wherein
 the buffer body includes three medium enclosing buffer members as the plurality of medium enclosing buffer members, and   each of the three medium enclosing buffer members has two buffer parts as the plurality of buffer parts.   
     
     
         3 . The transport box according to  claim 2 , wherein
 the buffer body includes two medium enclosing buffer members as the plurality of medium enclosing buffer members, and   each of the two medium enclosing buffer members has three buffer parts as the plurality of buffer parts.   
     
     
         4 . The transport box according to  claim 1 , further comprising a fixing member that fixes the buffer parts to the inner surface of the outer box. 
     
     
         5 . The transport box according to  claim 1 , wherein
 each of the buffer parts includes   at least one buffer chamber in which the medium is sealed, and   an edge part formed around the at least one buffer chamber.   
     
     
         6 . The transport box according to  claim 5 , wherein the at least one buffer chamber includes a plurality of buffer chambers arranged in a direction orthogonal to a direction in which the plurality of buffer parts is arranged with the communication flow path interposed therebetween. 
     
     
         7 . The transport box according to  claim 5 , wherein at least a portion of the edge part in one of the plurality of medium enclosing buffer members is connected to a portion of the edge part in another of the plurality of medium enclosing buffer members. 
     
     
         8 . The transport box according to  claim 6 , wherein the resin sheet constituting one of the plurality of buffer chambers in one of the plurality of medium enclosing buffer members is connected to the resin sheet constituting one of the plurality of buffer chambers in another of the plurality of medium enclosing buffer members. 
     
     
         9 . The transport box according to  claim 1 , wherein the communication flow path is bent or curved. 
     
     
         10 . The transport box according to  claim 1 , wherein the resin sheet has airtightness.
