Cushioning member and packaging device

Abstract

[Problem] Provided is a cushioning member and a packaging device which have enough capability of protecting an object to be packaged and improving a packaging efficiency. [Solution] The disclosed cushioning member is arranged in a packaging box and is the cushioning member for protecting the object to be packaged, and includes a plurality of cushion elements in which a holding part which holds said object to be packaged is formed in a surface side and at least one projection part is formed in the other surface side respectively, and a fixing member in which through holes through which said projection part of each said cushion element can pierce are formed at predetermined positions and movements of each said cushion element are restricted by inserting each said projection part in said corresponding through hole, wherein said projection parts pierce said through holes and a tip end part of each said projection part contacts with an inner wall side of said packaging box in the case of arranging each said cushion element which is fixed by said fixing member in said packaging box.

1 . A cushioning member which is arranged in a packaging box and protects an object to be packaged, comprising:
 a plurality of cushion elements in which a holding part which holds said object to be packaged is formed in a surface side and at least a projection part is formed in the other surface side; and   a fixing member in which a through hole which said projection part of each said cushion element can pierce is formed at a predetermined position and movements of each said cushion element are restricted by each said projection part being inserted in said corresponding through hole, wherein   said projection part pierces said through hole and a tip end part of said projection part contacts with an inner wall side of said packaging box in the case of arranging each said cushion element which is fixed by said fixing member in said packaging box.   
     
     
         2 . The cushioning member according to  claim 1 , wherein
 said cushion element is fixed at each end part of a pair of opposing side which faces in a first direction of said fixing member.   
     
     
         3 . The cushioning member according to  claim 2 , wherein
 a bending part is formed at each end part of a pair of opposing side which faces in a second direction which crosses at right angle with said first direction of said fixing member, and wherein   each bending part is inserted in each groove part formed at both of the end parts of each said cushion element.   
     
     
         4 . The cushioning member according to  claim 2 , wherein
 said fixing member is formed by corrugated fiberboard sheets and said first direction is a direction which is the same as a fluted direction of the corrugated fiberboard sheets.   
     
     
         5 . The cushioning member according to  claim 1 , wherein
 said projection part is formed one by one at both of each end part of each said cushion element.   
     
     
         6 . The cushioning member according to  claim 1 , wherein
 a hole part through which a convex part formed in said object to be packaged can pierce is formed at a predetermined position of said fixing member, and a space formed by said projection part, said fixing member and the inner wall side of said packaging box accommodates said convex part.   
     
     
         7 . The cushioning member according to  claim 1 , wherein
 size of said through hole is adjusted to smaller than size of said projection part and cuts are arranged around said through hole.   
     
     
         8 . The cushioning member according to  claim 1 , wherein
 said projection part has a shape which gradually becomes large from a base.   
     
     
         9 . A packaging device, comprising:
 a packaging box; and   the cushioning member according to  claim 1  which is arranged in the packaging box and protects the object to be packaged.   
     
     
         10 . The packaging device according to  claim 9 , further comprising:
 said cushioning member which is arranged at an upper part of said object to be packaged and protects the object to be packaged; and   another cushioning member which is arranged at a bottom part of said packaging box, possesses holding parts corresponding to shape of the bottom part of said object to be packaged and protects said object to be packaged.
