Carton with improved folding

Abstract

The present invention provides a carton ( 100 ) made of paperboard having flaps ( 101, 105 ), the carton ( 100 ) comprising, at least one score ( 102 ) along a crease line ( 103 ) of at least one flap ( 101, 105 ), wherein the score ( 102 ) is 25% to 85% of thickness of the paperboard and 5% to 70% of length of the crease line ( 103 ). The invention also provides a method of securing flaps ( 101, 105 ) of the carton ( 100 ).

1 . A carton ( 100 ) made of paperboard, having flaps ( 101 ,  105 ), the carton ( 100 ) comprising,
 at least one score ( 102 ) along a crease line ( 103 ) of at least one flap ( 101 ,  105 ),   wherein the score ( 102 ) is 25% to 85% of thickness ( 104 ) of the paperboard and 5% to 70% of length of the crease line ( 103 ).   
     
     
         2 . A carton as claimed in  claim 1 , wherein the score ( 102 ) is 30% to 70% of the thickness ( 104 ) of the paperboard. 
     
     
         3 . A carton as claimed in  claim 1 , wherein the score ( 102 ) is 50% to 60% of the thickness ( 104 ) of the paperboard. 
     
     
         4 . A carton as claimed in  claim 1 , wherein the score ( 102 ) is 20% to 65% of the length of the crease line ( 103 ). 
     
     
         5 . A carton as claimed in  claim 1 , wherein the score ( 102 ) is 40% to 60% of the length of the crease line ( 103 ). 
     
     
         6 . A carton as claimed  claim 1 , wherein the score ( 102 ) is at the crease line ( 103 ) of each flap ( 101 ,  105 ). 
     
     
         7 . A blank for making the carton ( 100 ) as claimed in  claim 1 . 
     
     
         8 . A method of securing flaps ( 101 ,  105 ) of a carton ( 100 ) made of paperboard, the method comprising,
 making at least one score ( 102 ) along a crease line ( 103 ) of at least one flap ( 101 ,  105 ),   wherein the score ( 102 ) is 25% to 85% of thickness ( 104 ) of the paperboard, and is 5% to 70% of length of the crease line ( 103 ).   
     
     
         9 . A method as claimed in  claim 8 , wherein the score is 30% to 70% of the thickness of the paperboard. 
     
     
         10 . A method as claimed in  claim 8 , wherein the score is 50% to 60% of the thickness ( 104 ) of the paperboard. 
     
     
         11 . A method as claimed in  claim 8 , wherein the score is 20% to 65% of length of the crease line ( 103 ). 
     
     
         12 . A method as claimed in  claim 8 , wherein the score is 40% to 60% of length of the crease line ( 103 ).
