Abstract
A reclosable package comprises a body member of semi-rigid preformed plastic with a first planar marginal portion and a central portion shaped to provide a packaging chamber. A base member has a corresponding second planar marginal portion and a central panel to provide a closure for the packaging chamber. The body member and base member are permanently bonded along one pair of adjacent sides of the first and second planar marginal portions. A hinge is situated within the pair of adjacent sides, which automatically locks when the package is open and unlocks when the package is closed. The hinge may comprise a line of perforations with integral locking tabs situated in one of the sides, or in a mat interposed between the sides. Different patterns of cut configurations may be employed as the hinge as long as the hinge includes areas which protrude to hold the package open when the lid is rotated past 90 to the open position.
