PROBLEM TO BE SOLVED: To provide an easily openable container so devised that the container can be easily opened even by an infant up to an elderly person, when a seal end carton having zipper is to be opened. SOLUTION: In the easily openable container, the tab of an opening zipper is easily picked up by being more broadened than other sections, two-row parallel sections of the opening zipper are of a shape where slanted ruled lines are continuously provided in a plurality of intermittently cut ruled lines at an obtuse angle in opposite internal directions. An slantly broadened section near the tab is of a shape where slanted ruled lines are continuously provided at a plurality of intermittently cut ruled lines at an obtuse angle in opposite external directions, so that the opening zipper is easily torn by allowing a slantly cut ruled line in the knob section to be continuously and smoothly torn. In addition, an inwardly depressed recess formed section is provided at a side plate section contacting the tab by the folded line or the ruled line and the folded line so as to be easily bent inside the side plate contacting the tab by pressing it with a finger.
