Abstract: A closure including an improved hinge includes a cap member selectively coupleable to a container to cover an opening in the container. The cap member includes a first substantially planar member, a depending skirt and an aperture formed through the first substantially planar member. A solid member integrally formed with the cap member projects out of the first substantially planar member. The solid member includes an upper surface and two opposed side surfaces, with each of the opposed side surfaces having an indentation formed therein. The closure further includes a flip top having a plug wherein, when the flip top is in a closed position, the plug seals the aperture formed in the first substantially planar member and the flip top covers substantially all of the first planar member, wherein the flip top includes a cut-out area to accommodate the solid member so that, when the flip top is in the closed position, the flip top and the upper surface of the solid member form a substantially continuous surface.

Abstract: An improved flip top closure device for a dispensing opening of a container, comprising a first body member with a flip top adapted to be mounted on the container, and a second body member mounted on the first body member and having a part which is usually in overlapping relation with the flip top to prevent opening thereof, which part is displaceable from said overlapping relation to expose the edge of the flip top for opening thereof and which, by virtue of spring tabs which provide restorative force, will return to the overlapping position without need for external physical manipulation.

Abstract: This invention relates to two-piece child resistant closures which utilize a ratchet feature to screw on the closure and, more specifically, to a two-piece child resistant closure wherein a particular ratchet configuration and placement of the elements thereof provides negligible reverse torque during undepressed counter-clockwise rotation of the outer closure member. Negligible reverse torque is defined as the torque caused by frictional contact of the outer and inner cap members when the undepressed closure is turned in the removal direction is insufficient to cause the undesired or accidental removal of the closure from the container.
