Auxiliary unit

Abstract

An auxiliary unit that is disposed between a first packing material including a plurality of side surfaces and a second packing material loaded onto the first packing material in a direction of gravity and assists in loading the second packing material onto the first packing material, the auxiliary unit including a load receiving portion that is provided along the side surfaces of the first packing material on an upper side in a direction of gravity and receives a load of the second packing material.

What is claimed is: 
     
         1 . An auxiliary unit that is disposed between a first packing material including a plurality of side surfaces and a second packing material loaded onto the first packing material in a direction of gravity and assists in loading the second packing material onto the first packing material, the auxiliary unit comprising:
 a load receiving portion that is provided along the side surfaces of the first packing material on an upper side in a direction of gravity and receives a load of the second packing material.   
     
     
         2 . The auxiliary unit according to  claim 1 ,
 wherein the load receiving portion is disposed at upper ends of the side surfaces of the first packing material.   
     
     
         3 . The auxiliary unit according to  claim 2 ,
 wherein the load receiving portion is disposed above a groove-shaped connector that is connected in a case where the upper ends of the side surfaces of the first packing material are inserted into the connector.   
     
     
         4 . The auxiliary unit according to  claim 3 ,
 wherein a groove width of the connector is partially increased to correspond to a portion where thickness directions of the side surfaces of the first packing material overlap with each other.   
     
     
         5 . The auxiliary unit according to  claim 1 ,
 wherein the second packing material includes a plurality of side surfaces, and the auxiliary unit includes a load portion that is provided along the side surfaces of the second packing material on a lower side in a direction of gravity and is in contact with the load receiving portion.   
     
     
         6 . The auxiliary unit according to  claim 5 ,
 wherein in a case where the second packing material is loaded onto the first packing material, only the load portion and the load receiving portion are in contact with each other and a gap is formed between an upper portion of the first packing material and a lower portion of the second packing material.   
     
     
         7 . The auxiliary unit according to  claim 5 ,
 wherein the load receiving portion protrudes upward, and   
       the load portion is recessed upward. 
     
     
         8 . The auxiliary unit according to  claim 7 ,
 wherein the load receiving portion is formed in a shape of a linear projection extending in a horizontal direction, and   the load portion is formed in a shape of a groove to which the load receiving portion is fitted.   
     
     
         9 . The auxiliary unit according to  claim 5 ,
 wherein the load portion is formed integrally with a support part that supports the second packing material on an upper surface thereof.   
     
     
         10 . An auxiliary unit that is disposed between a first packing material including a plurality of side surfaces and a second packing material loaded onto the first packing material in a direction of gravity and assists in loading the second packing material onto the first packing material, the auxiliary unit comprising:
 a load receiving portion that is provided along the side surfaces of the first packing material on an upper side in a direction of gravity and receives a load of the second packing material.
