Abstract: Child resistant closures are typically two-piece assemblies or squeeze and turn closures with an inside wall and an outside wall. The current squeeze and turn child resistant closures are expensive and difficult for seniors to operate. The preferred design is a child-resistant single wall cap and container assembly that is preferably easy for seniors to open and difficult for children to open or is substantially child-resistant. In addition, due to the single wall of the cap and relatively low cap height, the preferred assembly is light, requires less material and relatively less expensive to manufacture than prior art container assemblies. Like many child resistant closure systems, the preferred container assembly design includes a container with specifically designed neck finish to lock the closure on the container. However, the preferred design includes two small lugs, which generally do not add significantly to the bottle complexity or bottle cost.

Abstract: A container and child-resistant closure assembly includes a cap formed from a single piece, a cup shaped inner member having a top wall, an outer wall, and a depending sidewall. The sidewall includes a threaded interior surface. The outside wall of the inner member includes connection members for securing to an outer member. The outer member has a ring-shape with a plurality of inwardly facing lugs. Each of the plurality of inwardly facing lugs is cylindrically-shaped and protrudes radially inwardly from the outer member. The container assembly also includes a container including a neck forming an opening. The neck has a threaded exterior surface and a plurality of ramps. Each of the plurality of ramps faces radially outwardly from the neck and has a gently sloping face and a steeply sloping face.

Abstract: A child-resistant container assembly for selectively storing materials is provided. The child-resistant container assembly includes a cap and a container. The cap has a top wall and a sidewall. First and second levers are positioned in respective gaps in the sidewall and are pivotably connected thereto via hinges. The container includes a neck positioned at an upper end thereof, having a radially outwardly extending, circumferentially tapering locking rib. The locking rib defines at least one locking edge, at a largest diameter of the locking rib, and at least one base edge, at a smallest diameter of the locking rib. To remove the cap from the container, the first and second levers are manually pivoted to clear the at least one locking edge, in order to permit sufficient rotation of the cap relative to the container to remove the cap from the container.
