Safety closure assembly

摘要: In a safety screw closure device an axially projecting skirt portion (20) of the outer cap (12) loosely encompasses (34) inner (14) to allow relative rotary movement between caps (12,14). Integrally molded with circular domeshaped top panel (47) there are provided plurality upwardly extending ratchet lugs (40) which in engagement (22) on interior end wall (18) (12). Thus removal is prevented unless pressed down overcome bias dome-shaped and thereby bring drive (26) downwardly from into members (52) integrally periphery (47). A reduced thickness annular may facilitate slippage (22,40), stop means be prevent overstressing deformation
