ABSTRACT:
A child-resistant molded plastic container lid for open head containers wherein a threaded connection is provided between the container and lid. The lid is provided with at least one and in certain instances with a pair of diametrically disposed resiliently biased locking members, pivotally connected to the closure, which cooperate with locking teeth on the container. The lever arms of the locking members are offset and substantially parallel to each other on opposite sides of the pivotal connection. An elliptical spring is integrally connected to each lever arm and cooperates with portions of a gusset wall enclosing the lever arm to provide continued biasing memory on the locking member. A seal arrangement is also provided between the lid and the container to provide a tight and rigid seal and to reinforce the top of the container and lid to prevent the lid from popping off the container when it is dropped while full of liquid or powder material.
