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.

[ What is claimed is:] [1.] A unitary child-resistant closure for pill containers, comprising:a substantially rectangular base portion having opposed first and second end walls and opposed first and second side walls, and defining an opening therebetween;a first fixed cover portion overlying more than 50% of said opening, more than 50% of said first and second side walls, and said second end wall;a second moveable closure member; anda hinge connecting said moveable closure member to said first end wall;wherein said second moveable closure member has first and second major surfaces;wherein said first major surface of said moveable closure member is the upper surface thereof when said moveable closure member is in its operative closure position so as to cover the remaining less then 50% of said opening, the remaining less than 50% of said first and second side walls, and said first end wall;wherein said second major surface of said moveable closure member is the lower surface thereof when said moveable closure member is in its operative closure position;wherein a camming member is upstanding from said second major surface of said moveable closure member at a first end thereof, and presents at least one sliding cam surface having a portion which is sloped in a direction towards said second major surface and having another portion slopped in a direction away from said hinge;wherein said camming member has first and second ends, with said sliding cam surface terminating at said first end thereof;wherein said first end of said camming member has a latch member formed therein, which latch member extends beyond said first end of said moveable closure member and is spaced away from said second major surface; andwherein a flexible spring member is formed between said second end of said camming member and said hinge, and terminates in said hinge at the end of said flexible spring member which is remote from said second end of said camming member;whereby, when said moveable closure member is in its operative closure position, said latch member extends beneath a first end of said fixed cover portion which is remote from said second end wall, and said first end of said moveable closure member is urged against said first end of said first fixed cover portion by the spring action of said flexible spring member.
