ABSTRACT:
A double wall squeeze-and-turn child-resistant safety closure wherein skirt flexure stiffening web ribs are integrally molded into the closure so as to extend radially between the mutually facing wall surfaces of the skirts. The ribs are arranged in two sets of diametrically opposed web pairs generally angularly registered with an associated one of the pair of diametrically opposed outer wall squeeze zones. Each rib is also integrally joined to the closure base wall and protrudes therefrom axially of the closure a predetermined distance greater than the axial thickness of the peripheral region of the closure base wall that is joined to the ribs to thereby shift the outer skirt wall flexure swing point. Each pair of ribs is angularly spaced from one another on the closure base wall one on either side of and closely adjacent to a plane oriented at about 90 degrees to a plane intersecting the closure CR lugs to further localize the squeeze zone area. A pair of pressure pads are located one in each of the outer skirt wall squeeze zones and form a radially thickened portion that further stiffens and localizes the flexure mode of the outer skirt. The outer skirt wall preferably also has wall thickening portions radially inwardly protruding from the inner surface thereof and generally angularly registered with the pressure pads and web ribs to further enhance the outer skirt flexure mode and further localize effective squeeze activation area of the outer skirt wall.
