ABSTRACT:
A child resistant package includes a plastic container and a plastic closure. The container includes a body and a finish having an opening. The closure includes a base wall, an outer flexible peripheral skirt and an inner peripheral skirt. Interengaging retaining means on the finish of the container and the inner skirt of said closure restrict relative movement between said container and closure to rotary movement. The plastic closure also includes opposed flexible portions on said outer skirt and opposed lugs on the inner surface of the outer skirt. The container has opposed lugs on the finish engaging said lugs on said closure precluding rotation of said closure unless said flexible portions of said skirt are squeezed. A portion of the base wall of the closure is hinged to the base wall and normally lies in the same plane as the base wall. The container has a securing bead on the finish and the top portion has means engaging the securing bead. The container includes an inclined ramp. A cam follower is provided on said top portion of the closure such that when the outer skirt of the closure is squeezed and rotated, the cam follower engages the inclined ramp and the top portion is released from said securing bead.
