A plastic dispensing closure including a closure body, a lid, a resilient 'living' hinge joining the lid to the closure body, and camming members defined between the lid and the closure body to temporarily deform the hinge, within its elastic limits, as the lid is moved between its opened and closed position. One end of the hinge is secured to a flexible holder situated at the rear of the closure. Such holder functions as a cantilever beam and serves as a spring to minimize the stress forces imposed upon the 'living' hinge. The closure body, lid, and hinge may be integrally molded, and the holder may be situated upon the closure body, or upon the lid, as design considerations dictate.
