A unitary child-resistant closure (10, 100) for pill containers (12), comprises a substantially rectangular base (20) having an opening (34) therein. A first fixed cover portion (30) overlies more than 50 % of the opening. There is a moveable closure member (40), and a hinge (32, 33) connecting the moveable closure member to the rectangular base. A camming member (46) is upstanding from the second major surface of the moveable closure member at the first end thereof, and presents a sliding cam surface (50) which is sloped in a direction towards the lower major surface and in t he direction away from the hinge. The first end camming member has a latch memb er formed therein. A flexible spring member (54) is formed between the second e nd of the camming member and the hinge, and terminates at one end thereof in th e hinge. When the moveable closure member is in its operative closure position , the latch member extends beneath a first end of the fixed cover portion, and the first end of the moveable closure member is urged against the first end of the first fixed cover portion by the spring action of the flexible spring member.
