ABSTRACT:
A package formed from a film of relatively stiff material is provided having an upwardly opening recess for containing an article. At least a portion of opposite side walls of the recess are inclined inwardly to engage and hold the article in the recess. An integral hinge is provided in the package along an axis of the recess permitting the base of the package to be bent along the hinge line to a position where the normally inwardly inclined side walls are parallel to one another to allow insertion of article into the recess. Thereafter, when the package assumes its flat position the walls of the recess incline inwardly and retain the article in the package. Also disclosed is a mold for forming the package and a method for inserting an article into the package.
