Abstract

A child resistant closure apparatus between a container and a cap comprises a separate safety lock ring. The lock ring is mounted over the container neck and the cap is mounted on the container neck and engages with a pair of lock clasps on opposite sides of the lock ring. Finger pads on opposite sides of the lock ring are squeezed and compressed by one hand of the user while the cap is rotated on the container neck by the other hand of the user to separate the cap from the container. The lock ring is designed to be employed with container and cap closure assemblies of at least two different sizes, reducing their manufacturing costs. Additionally, the lock ring may be removed from the container if it is desired that the container and cap not have a child resistant closure apparatus.

Claims25

Dependent claims

A child resistant closure apparatus comprising:

a container having an interior volume, an opening in the container providing access to the container interior volume through the opening, and a cylindrical neck on the container extending around the container opening, the neck having a center axis that defines mutually perpendicular axial and radial directions relative to the container;
a cap mounted on the container neck for rotation of the cap about the container neck axis, the cap having a lug that projects outwardly from a surface of the cap;
and
a clasp on the container adjacent the container neck and the cap, the clasp being resiliently movable along the radial direction between a first position of the clasp relative to the container and a second position of the clasp relative to the container where the clasp engages with the cap lug in the first position of the clasp preventing the cap from rotating on the container neck and the clasp is displaced from the cap lug in the second position of the clasp where the clasp does not prevent rotation of the cap on the container neck.
