Abstract: A child-resistant closure for liquid medicaments consisting of two parts, a dosage cup and a bottle adapter. Dosage cup is configured to have cap lugs which reversibly engage helical locking lugs. In thread-on bottle adapter embodiments, helical locking lugs are located on the bottle adapter. In press-in bottle adapter embodiments, helical locking lugs are located on the neck finish of the bottle. A downward force is required to close the system, said force deforming a flexible shoulder, which in turn, creates an upwardly biasing force acting on the dosage cup to lock it in place in a child-resistant manner.

Abstract: A passive valve closure for liquid medicaments, configured to permit irreversible attachment to a pre-existing bottle and reversible engagement with a dosage cup bearing lugs such that when the dosage cup engages skirt lugs on the closure, a child-resistant closure is effected.

Abstract: A system for producing blow molded articles. The system includes an injector nozzle mounted to a parison cavity block having a parison cavity such that the injector nozzle injects molten plastic into the parison cavity to form a parison. The injector nozzle is mounted to the parison block by means of two seats, a distal seat where the distal end of the injector nozzle is seated within an opening in the parison cavity block and a proximal seat, a linear distance inwardly from the distal seat, where a circular flange on the injector nozzle is seated within an annular shelf formed in the parison block. The two spaced apart seats ensure an accurate alignment between the centerline of the injector nozzle and the parison cavity. As a further feature, there is a system to heat the nozzle tip to reduce the temperature differential between the nozzle and the parison cavity.
