ABSTRACT:
A closure system for threaded containers wherein the closure is of the dispensing type and is child resistant in two aspects. Interengaging lugs on the closure skirt and container neck are so arranged that a squeezing force is required to permit the closure being unthreaded from the container. A dispensing opening in the closure top is closed by a hinged cap that meets with the upper rim of the closure in a parting line. At this parting line both the hinged cap and the top of the closure have matching protruberances that require the squeezing of the lower one in order to push up or release the cap. The plastic material of the cap and the closure are sufficiently strong that a child is unable to flex or squeeze the closure enough to open the cap or unthread the closure from the container.
