ABSTRACT:
A closable type container for packaging items is constructed of a one piece flat sheet of carton material which is cut and scored to facilitate erection into a box like structure. The closable or clam shell type structure includes an ergonomic toggle action tab having a circular or generally oval shape and a fold line which divides the tab into two tab sections. This ergonomic toggle action tab is movable from a normal position by inward digital pressure on the fold line. Further, radius score lines each have an arc shape which causes a depressed tab section to have a slightly concave surface. An offset fold line between the two tab sections is also disclosed.
