Abstract
A packing container having an outer casing and a package body disposed within the outer casing is disclosed. A wall portion of the package body is folded over and affixed to itself in the folded position, and a thin cutting thread is arranged within the folded wall portion so that the cutting thread is accessible from outside the packing container. Upon being pulled away from the wall portion, the cutting thread cuts through the wall portion to provide an opening in the package body.
