Child-resistant screw closure

摘要

A squeeze and turn child resistant package including a container having a finish (46) and a closure having a base wall (26) and an outer peripheral flexible wall (28) depending from the base wall. The wall has an internal thread on the inner surface thereof, the finish has an external thread thereon. The closure has an internal surface with spaced flexible chordal lugs (70) extending circumferentially in the direction of removal of the closure. The container finish has opposed radially extending abutments (52). Each abutment includes a radial abutting surface (54). The finish of the container includes an integral radial projection (56) adjacent the radial abutting surface of the abutment which has a lesser radial extent than the abutment. The radial projection has a chordal surface extending to the intersection of the radial abutting surface on he finish such that the chordal lug (70) on the closure is forced toward the intersection when a closure is rotated in a retrograde direction to remove the closure without flexing the peripheral wall. The finish has stops (50) below the threads engaging a blunt end leading end (51) of the thread on the closure to limit the movement of the closure and orient the closure. <IMAGE>
