Abstract
A safety closure and container assembly provided with a safety closure having a top wall and a downwardly-depending annular skirt.

The locking lugs are radially offset from the squeeze pads by about 90.degree. and are furthermore sized to engage a pair of cooperating locking tabs provided on the container neck. The locking lugs are back-angled and form an interior angle of at least 30.degree. with an imaginary line extending inwardly and normally from the inner surface of the annular skirt at respective base ends of the locking lugs.

The annular slots are located unsymmetrically between the locking lugs and the squeeze pads and are disposed through an arcuate distance of about 75.degree. beginning about 13.degree. from a centerpoint of each squeeze pad and extending in the direction of each respective locking lug. A safety closure is even further provided with a retaining bead projecting inwardly and downwardly from the inner surface o…
