| 主权项 | 1. A system (20; 302) comprising the unitarily molded single-piece combination of: a first portion (24; 324); a living hinge (22; 322); and a second portion (26; 326) coupled by the living hinge to the first portion and shiftable between a first condition and a second condition via rotation about the living hinge,wherein the living hinge comprises: an upper face (88) and a lower face (90); a first end (80) at the first portion; a second end (82) at the second portion; a proximal region wherein the upper face is lengthwise concave and the lower face is lengthwise convex; and a central portion (96), wherein in the as-molded condition a proximal-to-distal median of the hinge is generally upwardly convex and downwardly concave along the central portion and the upper face along the central portion is doubly convex and the lower face along the central portion is doubly concave. | ||
