         8 . The packaging container according to  claim 2 , wherein
 projections are formed on a bottom of the spacer block structure; and   grooves are formed on the bottom of the container body corresponding to the spacer block structure, such that the projections of the spacer block structure is able to be seated into the grooves.   
     
     
         9 . The packaging container according to  claim 8  wherein
 the grooves extend out of the receiving channel structure in a direction far away from an inner side wall of the container body, and 
 a distance by which they extends out of the receiving channel structure is equal to a length of the spacer block structure. 
 
     
     
         10 . The packaging container according to  claim 1  wherein
 a recess is formed on a bottom of the spacer block structure. 
 
     
     
         11 . The packaging container according to  claim 1  wherein
 the receiving channel structure is integrally formed with the container body. 
 
     
     
         12 . The packaging container according to  claim 1  wherein
 one or more receiving channel structure is arranged on each of four inner side walls of the container body; and 
 in the case where the receiving channel structures are arranged on each inner side wall of the container body, the receiving channel structures have the same construction and are uniformly arranged on the inner side wall of the container body. 
 
     
     
         13 . The packaging container according to  claim 12  wherein
 2 to 4 receiving channel structures are arranged on each of four inner side walls of the container body. 
 
     
     
         14 . A packaging method using the packaging container according to  claim 1 , wherein the method comprises steps of:
 adjusting the position of the spacer block structure within the receiving channel structure, according to the size of the plate shaped article to be placed in the container body;   engaging the spacer block structure with the receiving channel structure; and   placing the plate shaped article into a space within the container body confined by the spacer block structure.   
     
     
         15 . The method according to  claim 14 , wherein
 the receiving channel structure includes a pair of receiving channel bodies which are arranged in parallel at an interval and which are provided with teeth on inner sides thereof, respectively; and   the spacer block structure includes a spacer block body and teeth arranged on opposite sides of the spacer block body, such that the teeth of the spacer block body is able to be engaged with the teeth of the receiving channel bodies.
