Carton for granular materials

摘要

Disclosed is a carton for containing granular materials comprising a box having front, back and side panels to form an opening and a lid attached to an upper portion of the back panel for closing the opening. The lid comprises (a) a top panel for covering the opening upon closure of the lid, (b) font and side flaps extending fore the respective edges of the top panel for coveting the respective upper portions of the font and side panels upon closure of the lid, (c) an adhesion flap adhering to the back panel, and (d) a back flap attached to the top panel and the adhesion flap. A cutting line which is extending toward the top panel is formed at least in the back flap so that the lid can be opened completely (about 270 degrees from its closed position) without any damage to the carton structure.
