ABSTRACT:
A unitary dispensing closure having a lid mounted on a closure part or base in such a manner that the lid will automatically move toward either a closed or an opened position when it is released after being manipulated to any position between these two positions can be constructed so as to utilize the resiliency within a "live" hinge to provide the force necessary to move the lid. In any position intermediate these two positions the hinge connects to the lid and closure part or base so that contact between the lid and closure part causes temporary deformation of the hinge. As a result of the resiliency of the material in the hinge such temporary deformation is adequate to move the lid as described.
