摘要： Child-resistant closure comprises a closure neck with an opening surrounded by an inner and an outer wall and a closure cap with a skirt matingly engaged by the inner wall and extending to the outer wall, the outer wall including a deformable segment to permit inward finger deformation and upward pressure on the underside of the lip of the closure cap, with improvements comprising reinforcement means in the closure cap and/or closure neck to prevent radial deformation of the closure in the area of the opening, other than at the preselected outer wall deformable segment location. Preferably, the reinforcement means comprises radially disposed ribs associated with the closure cap and also radially disposed ribs extending between the inner and outer walls of the closure neck surrounding the opening thereof. Preferably also the closure includes an upwardly extending rim on the outer wall of the closure neck substantially surrounding the closure cap lip so as to preclude inadvertent or accidental upward movement of the closure due to frictional engagement of the exposed edge of the lip and to transmit inward radial force on the outer wall to the cap lip rather than to other portions of the closure cap.
