Prefab packaging box

Abstract

The present invention provides a prefab packaging box including a side part having an opening formed at an upper or lower side thereof, and a cover part that is formed to extend from an upper or lower corner of the side part and finishes the opening by being folded by an external force, wherein the cover part includes a pair of support covers which are formed to extend from opposite corners of the side part and in which auxiliary insertion grooves are formed, an inner cover which is formed to extend from one corner of the side part in which the support covers are not formed and in which a main insertion groove is formed, an outer cover that is formed to extend from the other corner of the side part in which the support covers are not formed, a main catching member which is formed on one side of the outer cover, is inserted into the main insertion groove, and is then fastened to the inner cover and the support covers; and a pair of auxiliary catching members which are formed on both sides of the outer cover, are inserted into the auxiliary insertion grooves, and are then fastened to the support covers.

1 . A prefab packaging box comprising:
 a side part having an opening formed at an upper or lower side; and   a cover part that is formed to extend from an upper or lower corner of the side part and finishes the opening by being folded by an external force,   wherein the cover part includes:   a pair of support covers which are formed to extend from opposite corners of the side part and in which auxiliary insertion grooves are formed;   an inner cover which is formed to extend from one corner of the side part in which the support covers are not formed and in which a main insertion groove is formed;   an outer cover that is formed to extend from the other corner of the side part in which the support covers are not formed;   a main catching member which is formed on one side of the outer cover, is inserted into the main insertion groove, and is then fastened to the inner cover and the support covers; and   a pair of auxiliary catching members which are formed on both sides of the outer cover, are inserted into the auxiliary insertion grooves, and are then fastened to the support covers.   
     
     
         2 . The prefab packaging box of  claim 1 , wherein the main catching member is inserted into the main insertion groove in a state in which both ends of the main catching member are folded, is then unfolded, and is thus fastened to the inner cover and the support covers. 
     
     
         3 . The prefab packaging box of  claim 1 , wherein the auxiliary catching members are inserted into the auxiliary insertion grooves in a state in which ends of the auxiliary catching members are folded, are then unfolded, and are thus fastened to the support covers. 
     
     
         4 . The prefab packaging box of  claim 2 , wherein both sides of the main insertion groove are bent at a predetermined angle so that an end of the main catching member is inserted thereinto in a folded state. 
     
     
         5 . The prefab packaging box of  claim 3 , wherein sides of the auxiliary catching grooves are bent at a predetermined angle so that ends of the auxiliary catching members are inserted thereinto in a folded state. 
     
     
         6 . The prefab packaging box of  claim 1 , wherein an end of the main catching member or the auxiliary catching members has a predetermined internal angle. 
     
     
         7 . The prefab packaging box of  claim 1 , wherein the side part has a pressing member formed at a position facing a portion in which the auxiliary catching members are arranged when the auxiliary catching members are inserted into the auxiliary insertion grooves.
