ABSTRACT:
A unitary child-resistant closure for pill containers, comprises a substantially rectangular base having an opening therein. A first fixed cover portion overlies more than 50% of the opening. There is a moveable closure member, and a hinge--usually, a living hinge--connecting the moveable closure member to the rectangular base. The moveable closure member has first and second major surfaces, which are its upper surface and lower surface when the moveable closure member is in its operative closure position. A camming member is upstanding from the second major surface of the moveable closure member at a first end thereof, and presents a sliding cam surface which is sloped in a direction towards the second major surface and away from the hinge. The first end of the camming member has a latch member formed therein, which extends beyond the first end of the moveable closure member and is spaced away from the second major surface by a distance which is at least equal to the thickness of the first fixed cover portion. A flexible spring member is formed between the second end of the camming member and the hinge, and terminates at one end thereof in the 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.
